Includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Entity may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits should not be reported as cash and cash equivalents.

Accounting Changes and Reclassification |
Accounting
Changes
Consolidation of Variable Interest Entities —
In June 2009, the Financial Accounting Standards Board, or FASB,
issued revised authoritative guidance associated with the
consolidation of variable interest entities. The new guidance
primarily uses a qualitative approach for determining whether an
enterprise is the primary beneficiary of a variable interest
entity, and is, therefore, required to consolidate the entity.
This new guidance generally defines the primary beneficiary as
the entity that has (i) the power to direct the activities
of the variable interest entity that can most significantly
impact the entity’s performance and (ii) the
obligation to absorb losses and the right to receive benefits
from the variable interest entity that could be significant from
the perspective of the entity. The new guidance also requires
that we continually reassess whether we are the primary
beneficiary of a variable interest entity rather than conducting
a reassessment only upon the occurrence of specific events.
As a result of our implementation of this guidance, effective
January 1, 2010, we deconsolidated certain capping,
closure, post-closure and environmental remediation trusts
because we share power over significant activities of these
trusts with others. Our financial interests in these entities
are discussed in Note 20. The deconsolidation of these
trusts has not materially affected our financial position,
results of operations or cash flows during the periods presented.
Business Combinations — In December 2007, the
FASB issued revisions to the authoritative guidance associated
with business combinations. This guidance clarified and revised
the principles for how an acquirer recognizes and measures
identifiable assets acquired, liabilities assumed, and any
noncontrolling interest in the acquiree. This guidance also
addressed the recognition and measurement of goodwill acquired
in business combinations and expanded disclosure requirements
related to business combinations. Effective January 1,
2009, we adopted the FASB’s revised guidance associated
with business combinations. The portions of this guidance that
relate to business combinations completed before January 1,
2009 did not have a material impact on our consolidated
financial statements. Further, business combinations completed
subsequent to January 1, 2009, which are discussed in
Note 19, have not been material to our financial position,
results of operations or cash flows. However, to the extent that
future business combinations are material, our adoption of the
FASB’s revised authoritative guidance associated with
business combinations may significantly impact our accounting
and reporting for future acquisitions, principally as a result
of (i) expanded requirements to value acquired assets,
liabilities and contingencies at their fair values when such
amounts can be determined and (ii) the requirement that
acquisition-related transaction and restructuring costs be
expensed as incurred rather than capitalized as a part of the
cost of the acquisition.
Noncontrolling Interests in Consolidated Financial
Statements — In December 2007, the FASB issued
authoritative guidance that established accounting and reporting
standards for noncontrolling interests in subsidiaries and for
the de-consolidation of a subsidiary. The guidance also
established that a noncontrolling interest in a subsidiary is an
ownership interest in the consolidated entity that should be
reported as equity in the consolidated financial statements. We
adopted this guidance on January 1, 2009. The presentation
and disclosure requirements of this guidance, which must be
applied retrospectively for all periods presented, resulted in
reclassifications to our prior period consolidated financial
information and the remeasurement of our 2008 effective tax
rate, which is discussed in Note 9.
Fair Value Measurements — In September 2006,
the FASB issued authoritative guidance associated with fair
value measurements. This guidance defined fair value,
established a framework for measuring fair value, and expanded
disclosures about fair value measurements. In February 2008, the
FASB delayed the effective date of the guidance for all
non-financial assets and non-financial liabilities, except those
that are measured at fair value on a recurring basis.
Accordingly, we adopted this guidance for assets and liabilities
recognized at fair value on a recurring basis effective
January 1, 2008 and adopted the guidance for non-financial
assets and liabilities measured on a non-recurring basis
effective January 1, 2009. The application of the fair
value framework did not have a material impact on our
consolidated financial position, results of operations or cash
flows.
Employers’ Accounting for Defined Benefit Pension and
Other Post-retirement Plans — In September 2006,
the FASB issued revisions to the authoritative guidance
associated with the accounting and reporting of post-retirement
benefit plans. This guidance required companies to recognize the
overfunded or underfunded status of their defined benefit
pension and other post-retirement plans as an asset or liability
and to recognize changes in that funded status through
comprehensive income in the year in which the changes occur. We
adopted these recognition provisions effective December 31,
2006. The FASB’s revised guidance also required companies
to measure the funded status of defined benefit pension and
other post-retirement plans as of their year-end reporting date.
These measurement date provisions were effective for us as of
December 31, 2008. We applied the measurement provisions by
measuring our benefit obligations as of September 30, 2007,
our prior measurement date, and recognizing a pro-rata share of
net benefit costs for the transition period from October 1,
2007 to December 31, 2008 as a cumulative effect of change
in accounting principle in retained earnings as of
December 31, 2008. The application of the recognition and
measurement provisions of this revised authoritative guidance
did not have a material impact on our financial position or
results of operations for the periods presented.
Subsequent Events — We have evaluated
subsequent events through the date and time the financial
statements were issued. No material subsequent events have
occurred since December 31, 2010 that required recognition
or disclosure in our current period financial statements.
Reclassifications
Certain minor reclassifications have been made to our prior
period consolidated financial information in order to conform to
the current year presentation.

Summary of Significant Accounting Policies |
Principles
of Consolidation
The accompanying Consolidated Financial Statements include the
accounts of WM, its wholly-owned and majority-owned subsidiaries
and certain variable interest entities for which we have
determined that we are the primary beneficiary. All material
intercompany balances and transactions have been eliminated.
Investments in entities in which we do not have a controlling
financial interest are accounted for under either the equity
method or cost method of accounting, as appropriate.
Estimates
and Assumptions
In preparing our financial statements, we make numerous
estimates and assumptions that affect the accounting for and
recognition and disclosure of assets, liabilities, equity,
revenues and expenses. We must make these estimates and
assumptions because certain information that we use is dependent
on future events, cannot be calculated with a high degree of
precision from data available or simply cannot be readily
calculated based on generally accepted methods. In some cases,
these estimates are particularly difficult to determine and we
must exercise significant judgment. In preparing our financial
statements, the most difficult, subjective and complex estimates
and the assumptions that present the greatest amount of
uncertainty relate to our accounting for landfills,
environmental remediation liabilities, asset impairments,
deferred income taxes, and reserves associated with our insured
and self-insured claims. Each of these items is discussed in
additional detail below. Actual results could differ materially
from the estimates and assumptions that we use in the
preparation of our financial statements.
Cash
and Cash Equivalents
Cash and cash equivalents consist primarily of cash on deposit
and money market funds that invest in U.S. government
obligations with original maturities of three months or less.
Concentrations
of Credit Risk
Financial instruments that potentially subject us to
concentrations of credit risk consist primarily of cash and cash
equivalents, investments held within our trust funds and escrow
accounts, accounts receivable and derivative instruments. We
make efforts to control our exposure to credit risk associated
with these instruments by (i) placing our assets and other
financial interests with a diverse group of credit-worthy
financial institutions; (ii) holding high-quality financial
instruments while limiting investments in any one instrument;
and (iii) maintaining strict policies over credit extension
that include credit evaluations, credit limits and monitoring
procedures, although generally we do not have collateral
requirements for credit extensions. We also control our exposure
associated with trade receivables by discontinuing service, to
the extent allowable, to non-paying customers. However, our
overall credit risk associated with trade receivables is limited
due to the large number of geographically diverse customers we
service. At December 31, 2010 and 2009, no single customer
represented greater than 5% of total accounts receivable.
Trade
and Other Receivables
Our receivables are recorded when billed or when cash is
advanced and represent claims against third parties that will be
settled in cash. The carrying value of our receivables, net of
the allowance for doubtful accounts, represents the estimated
net realizable value. We estimate our allowance for doubtful
accounts based on historical collection trends; type of
customer, such as municipal or commercial; the age of
outstanding receivables; and existing economic conditions. If
events or changes in circumstances indicate that specific
receivable balances may be impaired, further consideration is
given to the collectibility of those balances and the allowance
is adjusted accordingly. Past-due receivable balances are
written off when our internal collection efforts have been
unsuccessful. Also, we recognize interest income on long-term
interest-bearing notes receivable as the interest accrues under
the terms of the notes.
Landfill
Accounting
Cost Basis of Landfill Assets — We capitalize
various costs that we incur to make a landfill ready to accept
waste. These costs generally include expenditures for land
(including the landfill footprint and required landfill buffer
property); permitting; excavation; liner material and
installation; landfill leachate collection systems; landfill gas
collection systems; environmental monitoring equipment for
groundwater and landfill gas; and directly related engineering,
capitalized interest,
on-site road
construction and other capital infrastructure costs. The cost
basis of our landfill assets also includes asset retirement
costs, which represent estimates of future costs associated with
landfill capping, closure and post-closure activities. These
costs are discussed below.
Capping, Closure and Post-Closure Costs —
Following is a description of our asset retirement activities
and our related accounting:
We develop our estimates of these obligations using input from
our operations personnel, engineers and accountants. Our
estimates are based on our interpretation of current
requirements and proposed regulatory changes and are intended to
approximate fair value. Absent quoted market prices, the
estimate of fair value is based on the best available
information, including the results of present value techniques.
In many cases, we contract with third parties to fulfill our
obligations for capping, closure and post-closure. We use
historical experience, professional engineering judgment and
quoted and actual prices paid for similar work to determine the
fair value of these obligations. We are required to recognize
these obligations at market prices whether we plan to contract
with third parties or perform the work ourselves. In those
instances where we perform the work with internal resources, the
incremental profit margin realized is recognized as a component
of operating income when the work is performed.
Once we have determined the capping, closure and post-closure
costs, we inflate those costs to the expected time of payment
and discount those expected future costs back to present value.
During the years ended December 31, 2010, 2009 and 2008, we
inflated these costs in current dollars until the expected time
of payment using an inflation rate of 2.5%. We discount these
costs to present value using the credit-adjusted, risk-free rate
effective at the time an obligation is incurred, consistent with
the expected cash flow approach. Any changes in expectations
that result in an upward revision to the estimated cash flows
are treated as a new liability and discounted at the current
rate while downward revisions are discounted at the historical
weighted-average rate of the recorded obligation. As a result,
the credit-adjusted, risk-free discount rate used to calculate
the present value of an obligation is specific to each
individual asset retirement obligation. The weighted-average
rate applicable to our asset retirement obligations at
December 31, 2010 is between 6.0% and 8.0%, the range of
the credit-adjusted, risk-free discount rates effective since we
adopted the FASB’s authoritative guidance related to asset
retirement obligations in 2003. We expect to apply a
credit-adjusted, risk-free discount rate of 5.5% to liabilities
incurred in the first quarter of 2011.
We record the estimated fair value of capping, closure and
post-closure liabilities for our landfills based on the capacity
consumed through the current period. The fair value of capping
obligations is developed based on our estimates of the airspace
consumed to date for each capping event and the expected timing
of each capping event. The fair value of closure and
post-closure obligations is developed based on our estimates of
the airspace consumed to date for the entire landfill and the
expected timing of each closure and post-closure activity.
Because these
obligations are measured at estimated fair value using present
value techniques, changes in the estimated cost or timing of
future capping, closure and post-closure activities could result
in a material change in these liabilities, related assets and
results of operations. We assess the appropriateness of the
estimates used to develop our recorded balances annually, or
more often if significant facts change.
Changes in inflation rates or the estimated costs, timing or
extent of future capping and closure and post-closure activities
typically result in both (i) a current adjustment to the
recorded liability and landfill asset; and (ii) a change in
liability and asset amounts to be recorded prospectively over
either the remaining capacity of the related discrete capping
event or the remaining permitted and expansion airspace (as
defined below) of the landfill. Any changes related to the
capitalized and future cost of the landfill assets are then
recognized in accordance with our amortization policy, which
would generally result in amortization expense being recognized
prospectively over the remaining capacity of the capping event
or the remaining permitted and expansion airspace of the
landfill, as appropriate. Changes in such estimates associated
with airspace that has been fully utilized result in an
adjustment to the recorded liability and landfill assets with an
immediate corresponding adjustment to landfill airspace
amortization expense.
During the years ended December 31, 2010, 2009 and 2008,
adjustments associated with changes in our expectations for the
timing and cost of future capping, closure and post-closure of
fully utilized airspace resulted in $13 million,
$14 million and $3 million in net credits to landfill
airspace amortization expense, respectively, with the majority
of these credits resulting from revised estimates associated
with capping changes. In managing our landfills, our engineers
look for ways to reduce or defer our construction costs,
including capping costs. The benefit recognized in these years
was generally the result of (i) concerted efforts to
improve the operating efficiencies of our landfills and volume
declines, both of which have allowed us to delay spending for
capping activities; (ii) effectively managing the cost of
capping material and construction; or (iii) landfill
expansions that resulted in reduced or deferred capping costs.
Interest accretion on capping, closure and post-closure
liabilities is recorded using the effective interest method and
is recorded as capping, closure and post-closure expense, which
is included in “Operating” costs and expenses within
our Consolidated Statements of Operations.
Amortization of Landfill Assets — The
amortizable basis of a landfill includes (i) amounts
previously expended and capitalized; (ii) capitalized
landfill capping, closure and post-closure costs;
(iii) projections of future purchase and development costs
required to develop the landfill site to its remaining permitted
and expansion capacity; and (iv) projected asset retirement
costs related to landfill capping, closure and post-closure
activities.
Amortization is recorded on a
units-of-consumption
basis, applying expense as a rate per ton. The rate per ton is
calculated by dividing each component of the amortizable basis
of a landfill by the number of tons needed to fill the
corresponding asset’s airspace. For landfills that we do
not own, but operate through operating or lease arrangements,
the rate per ton is calculated based on expected capacity to be
utilized over the lesser of the contractual term of the
underlying agreement or the life of the landfill.
We apply the following guidelines in determining a
landfill’s remaining permitted and expansion airspace:
For unpermitted airspace to be initially included in our
estimate of remaining permitted and expansion airspace, the
expansion effort must meet all of the criteria listed above.
These criteria are evaluated by our field-based engineers,
accountants, managers and others to identify potential obstacles
to obtaining the permits. Once the unpermitted airspace is
included, our policy provides that airspace may continue to be
included in remaining permitted and expansion airspace even if
these criteria are no longer met, based on the facts and
circumstances of a specific landfill. In these circumstances,
continued inclusion must be approved through a landfill-specific
review process that includes approval by our Chief Financial
Officer and a review by the Audit Committee of our Board of
Directors on a quarterly basis. Of the 33 landfill sites
with expansions at December 31, 2010, 14 landfills
required the Chief Financial Officer to approve the inclusion of
the unpermitted airspace. Eight of these landfills required
approval by our Chief Financial Officer because of community or
political opposition that could impede the expansion process.
The remaining six landfills required approval primarily due to
the permit application processes not meeting the one- or
five-year requirements.
When we include the expansion airspace in our calculations of
remaining permitted and expansion airspace, we also include the
projected costs for development, as well as the projected asset
retirement costs related to capping, closure and post-closure of
the expansion in the amortization basis of the landfill.
Once the remaining permitted and expansion airspace is
determined in cubic yards, an airspace utilization factor, or
AUF, is established to calculate the remaining permitted and
expansion capacity in tons. The AUF is established using the
measured density obtained from previous annual surveys and is
then adjusted to account for settlement. The amount of
settlement that is forecasted will take into account several
site-specific factors including current and projected mix of
waste type, initial and projected waste density, estimated
number of years of life remaining, depth of underlying waste,
anticipated access to moisture through precipitation or
recirculation of landfill leachate, and operating practices. In
addition, the initial selection of the AUF is subject to a
subsequent multi-level review by our engineering group, and the
AUF used is reviewed on a periodic basis and revised as
necessary. Our historical experience generally indicates that
the impact of settlement at a landfill is greater later in the
life of the landfill when the waste placed at the landfill
approaches its highest point under the permit requirements.
After determining the costs and remaining permitted and
expansion capacity at each of our landfills, we determine the
per ton rates that will be expensed as waste is received and
deposited at the landfill by dividing the costs by the
corresponding number of tons. We calculate per ton amortization
rates for each landfill for assets associated with each capping
event, for assets related to closure and post-closure activities
and for all other costs capitalized or to be capitalized in the
future. These rates per ton are updated annually, or more often,
as significant facts change.
It is possible that actual results, including the amount of
costs incurred, the timing of capping, closure and post-closure
activities, our airspace utilization or the success of our
expansion efforts could ultimately turn out to be significantly
different from our estimates and assumptions. To the extent that
such estimates, or related assumptions, prove to be
significantly different than actual results, lower profitability
may be experienced due to higher amortization rates or higher
expenses, or higher profitability may result if the opposite
occurs. Most significantly, if it is determined that expansion
capacity should no longer be considered in calculating the
recoverability of a landfill asset, we may be required to
recognize an asset impairment or incur significantly higher
amortization expense. If it is determined that the likelihood of
receiving an expansion permit has become remote, the capitalized
costs related to the expansion effort are expensed immediately.
Environmental
Remediation Liabilities
We are subject to an array of laws and regulations relating to
the protection of the environment. Under current laws and
regulations, we may have liabilities for environmental damage
caused by operations, or for damage caused by conditions that
existed before we acquired a site. These liabilities include
potentially responsible party (“PRP”) investigations,
settlements, and certain legal and consultant fees, as well as
costs directly associated with site investigation and clean up,
such as materials, external contractor costs and incremental
internal costs directly related to the remedy. We provide for
expenses associated with environmental remediation obligations
when such amounts are probable and can be reasonably estimated.
We routinely review and evaluate sites that require remediation
and determine our estimated cost for the likely remedy based on
a number of estimates and assumptions.
Where it is probable that a liability has been incurred, we
estimate costs required to remediate sites based on
site-specific facts and circumstances. We routinely review and
evaluate sites that require remediation, considering whether we
were an owner, operator, transporter, or generator at the site,
the amount and type of waste hauled to the site and the number
of years we were associated with the site. Next, we review the
same type of information with respect to other named and unnamed
PRPs. Estimates of the costs for the likely remedy are then
either developed using our internal resources or by third-party
environmental engineers or other service providers. Internally
developed estimates are based on:
Estimating our degree of responsibility for remediation is
inherently difficult. We recognize and accrue for an estimated
remediation liability only when we determine that such liability
is both probable and reasonably estimable. Determining the
method and ultimate cost of remediation requires that a number
of assumptions be made. There can sometimes be a range of
reasonable estimates of the costs associated with the
investigation of the extent of environmental impact and
identification of likely site-remediation alternatives. In these
cases, we use the amount within a range that constitutes our
best estimate. If no amount within the range appears to be a
better estimate than any other, we use the amount that is the
low end of such range. If we used the high ends of such ranges,
our aggregate potential liability would be approximately
$150 million higher than the $284 million recorded in
the Consolidated Financial Statements as of December 31,
2010. Our ultimate responsibility may differ materially from
current estimates. It is possible that technological, regulatory
or enforcement developments, the results of environmental
studies, the inability to identify other PRPs, the inability of
other PRPs to contribute to the settlements of such liabilities,
or other factors could require us to record additional
liabilities. Our ongoing review of our remediation liabilities
could result in revisions to our accruals that could cause
upward or downward adjustments to income from operations. These
adjustments could be material in any given period.
Where we believe that both the amount of a particular
environmental remediation liability and the timing of the
payments are reliably determinable, we inflate the cost in
current dollars (by 2.5% at both December 31, 2010 and
2009) until the expected time of payment and discount the
cost to present value using a risk-free discount rate, which is
based on the rate for United States Treasury bonds with a term
approximating the weighted average period until settlement of
the underlying obligation. We determine the risk-free discount
rate and the inflation rate on an annual basis unless interim
changes would significantly impact our results of operations.
For remedial liabilities that have been discounted, we include
interest accretion, based on the effective interest method, in
“Operating” costs and expenses in our Consolidated
Statements of Operations. The following table summarizes the
impacts of revisions in the risk-free discount rate applied to
our environmental remediation liabilities and recovery assets
during the reported periods (in millions) and the risk-free
discount rate applied as of each reporting date:
The portion of our recorded environmental remediation
liabilities that has never been subject to inflation or
discounting, as the amounts and timing of payments are not
readily determinable, was $81 million at December 31,
2010 and $44 million at December 31, 2009. Had we not
inflated and discounted any portion of our environmental
remediation liability, the amount recorded would have increased
by $15 million and $20 million at December 31,
2010 and 2009, respectively.
Property
and Equipment (exclusive of landfills, discussed
above)
We record property and equipment at cost. Expenditures for major
additions and improvements are capitalized and maintenance
activities are expensed as incurred. We depreciate property and
equipment over the estimated useful life of the asset using the
straight-line method. We assume no salvage value for our
depreciable property and equipment. When property and equipment
are retired, sold or otherwise disposed of, the cost and
accumulated depreciation are removed from our accounts and any
resulting gain or loss is included in results of operations as
an offset or increase to operating expense for the period.
The estimated useful lives for significant property and
equipment categories are as follows (in years):
We include capitalized costs associated with developing or
obtaining internal-use software within furniture, fixtures and
office equipment. These costs include direct external costs of
materials and services used in developing or obtaining the
software and internal costs for employees directly associated
with the software development project. As of December 31,
2010, capitalized costs for software placed in service, net of
accumulated depreciation, were $44 million. In addition,
our furniture, fixtures and office equipment includes
$51 million as of December 31, 2010 and
$46 million as of December 31, 2009 for costs incurred
for software under development.
Leases
We lease property and equipment in the ordinary course of our
business. Our most significant lease obligations are for
property and equipment specific to our industry, including real
property operated as a landfill, transfer station or
waste-to-energy
facility. Our leases have varying terms. Some may include
renewal or purchase options, escalation clauses, restrictions,
penalties or other obligations that we consider in determining
minimum lease payments. The leases are classified as either
operating leases or capital leases, as appropriate.
Operating Leases (excluding landfills discussed
below) — The majority of our leases are operating
leases. This classification generally can be attributed to
either (i) relatively low fixed minimum lease payments as a
result of real property lease obligations that vary based on the
volume of waste we receive or process or (ii) minimum lease
terms that are much shorter than the assets’ economic
useful lives. Management expects that in the normal course of
business our operating leases will be renewed, replaced by other
leases, or replaced with fixed asset expenditures. Our rent
expense during each of the last three years and our future
minimum operating lease payments for each of the next five years
for which we are contractually obligated as of December 31,
2010 are disclosed in Note 11.
Capital Leases (excluding landfills discussed
below) — Assets under capital leases are
capitalized using interest rates determined at the inception of
each lease and are amortized over either the useful life of the
asset or the lease term, as appropriate, on a straight-line
basis. The present value of the related lease payments is
recorded as a debt obligation. Our future minimum annual capital
lease payments are included in our total future debt obligations
as disclosed in Note 7.
Landfill Leases — From an operating
perspective, landfills that we lease are similar to landfills we
own because generally we own the landfill’s operating
permit and will operate the landfill for the entire lease term,
which in many cases is the life of the landfill. As a result,
our landfill leases are generally capital leases. The most
significant portion of our rental obligations for landfill
leases is contingent upon operating factors such as disposal
volumes and often there are no contractual minimum rental
obligations. Contingent rental obligations are expensed as
incurred. For landfill capital leases that provide for minimum
contractual rental obligations, we record the present value of
the minimum obligation as part of the landfill asset, which is
amortized on a
units-of-consumption
basis over the shorter of the lease term or the life of the
landfill.
Acquisitions
We generally recognize assets acquired and liabilities assumed
in business combinations, including contingent assets and
liabilities, based on fair value estimates as of the date of
acquisition.
Contingent Consideration — In certain
acquisitions, we agree to pay additional amounts to sellers
contingent upon achievement by the acquired businesses of
certain negotiated goals, such as targeted revenue levels,
targeted disposal volumes or the issuance of permits for
expanded landfill airspace. For acquisitions completed in 2009
and 2010, we have recognized liabilities for these contingent
obligations based on their estimated fair value at the date of
acquisition with any differences between the acquisition-date
fair value and the ultimate settlement of the obligations being
recognized as an adjustment to income from operations. For
acquisitions completed before 2009, these obligations were
recognized as incurred and accounted for as an adjustment to the
initial purchase price of the acquired assets.
Acquired Assets and Assumed Liabilities —
Assets and liabilities arising from contingencies such as
pre-acquisition environmental matters and litigation are
recognized at their acquisition-date fair value when their
respective fair values can be determined. If the fair values of
such contingencies cannot be determined, they are recognized at
the acquisition date if the contingencies are probable and an
amount can be reasonably estimated. Acquisition-date fair value
estimates are revised as necessary and accounted for as an
adjustment to income from operations if, and when, additional
information regarding these contingencies becomes available to
further define and quantify assets acquired and liabilities
assumed.
Beginning in 2009, all acquisition-related transaction costs
have been expensed as incurred. For acquisitions completed
before 2009, direct costs incurred for a business combination
were accounted for as part of the cost of the acquired business.
Goodwill
and Other Intangible Assets
Goodwill is the excess of our purchase cost over the fair value
of the net assets of acquired businesses. We do not amortize
goodwill, but as discussed in the “Asset Impairments”
section below, we assess our goodwill for impairment at least
annually.
Other intangible assets consist primarily of customer contracts,
customer lists, covenants
not-to-compete,
licenses, permits (other than landfill permits, as all
landfill-related intangible assets are combined with landfill
tangible assets and amortized using our landfill amortization
policy), and other contracts. Other intangible assets are
recorded at cost and are generally amortized using either a 150%
declining balance approach or a straight-line basis as we
determine appropriate. Customer contracts and customer lists are
typically amortized over ten years. Covenants
not-to-compete
are amortized over the term of the non-compete covenant, which
is generally two to five years. Licenses, permits and other
contracts are amortized over the definitive terms of the related
agreements. If the underlying agreement does not contain
definitive terms and the useful life is determined to be
indefinite, the asset is not amortized.
Asset
Impairments
We monitor the carrying value of our long-lived assets for
potential impairment and test the recoverability of such assets
whenever events or changes in circumstances indicate that their
carrying amounts may not be recoverable. These events or changes
in circumstances are referred to as impairment indicators. If an
impairment indicator occurs, we perform a test of recoverability
by comparing the carrying value of the asset or asset group to
its undiscounted expected future cash flows. If cash flows
cannot be separately and independently identified for a single
asset, we will determine whether an impairment has occurred for
the group of assets for which we can identify the projected cash
flows. If the carrying values are in excess of undiscounted
expected future cash flows, we measure any impairment by
comparing the fair value of the asset or asset group to its
carrying value. Fair value is generally determined by
considering (i) internally developed discounted projected
cash flow analysis of the asset or asset group; (ii) actual
third-party valuations;
and/or
(iii) information available regarding the current market
for similar assets. If the fair value of an asset or asset group
is determined to be less than the carrying amount of the asset
or asset group, an impairment in the amount of the difference is
recorded in the period that the impairment indicator occurs and
is included in the “(Income) expense from divestitures,
asset impairments and unusual items” line item in our
Consolidated Statement of Operations. Estimating future cash
flows requires significant judgment and projections may vary
from the cash flows eventually realized, which could impact our
ability to accurately assess whether an asset has been impaired.
There are additional considerations for impairments of landfills
and goodwill, as described below.
Landfills — Certain impairment indicators
require significant judgment and understanding of the waste
industry when applied to landfill development or expansion
projects. For example, a regulator may initially deny a landfill
expansion permit application though the expansion permit is
ultimately granted. In addition, management may periodically
divert waste from one landfill to another to conserve remaining
permitted landfill airspace. Therefore, certain events could
occur in the ordinary course of business that are not
necessarily considered indicators of impairment of our landfill
assets due to the unique nature of the waste industry.
Goodwill — At least annually, we assess our
goodwill for impairment. We assess whether an impairment exists
by comparing the fair value of each operating segment to its
carrying value, including goodwill. We use a combination of two
valuation methods, a market approach and an income approach, to
estimate the fair value of our operating segments. Fair value
computed by these two methods is arrived at using a number of
factors, including projected future operating results, economic
projections, anticipated future cash flows, comparable
marketplace data and the cost of capital. There are inherent
uncertainties related to these factors and to our judgment in
applying
them to this analysis. However, we believe that these two
methods provide a reasonable approach to estimating the fair
value of our operating segments.
The market approach estimates fair value by measuring the
aggregate market value of publicly-traded companies with similar
characteristics to our business as a multiple of their reported
cash flows. We then apply that multiple to our operating
segments’ cash flows to estimate their fair values. We
believe that this approach is appropriate because it provides a
fair value estimate using valuation inputs from entities with
operations and economic characteristics comparable to our
operating segments.
The income approach is based on the long-term projected future
cash flows of our operating segments. We discount the estimated
cash flows to present value using a weighted-average cost of
capital that considers factors such as the timing of the cash
flows and the risks inherent in those cash flows. We believe
that this approach is appropriate because it provides a fair
value estimate based upon our operating segments’ expected
long-term performance considering the economic and market
conditions that generally affect our business.
Additional impairment assessments may be performed on an interim
basis if we encounter events or changes in circumstances that
would indicate that, more likely than not, the carrying value of
goodwill has been impaired. Refer to Note 6 for additional
information related to goodwill impairment considerations made
during the reported periods.
Restricted
Trust and Escrow Accounts
As of December 31, 2010, our restricted trust and escrow
accounts consist principally of (i) funds deposited for
purposes of settling landfill capping, closure, post-closure and
environmental remediation obligations; and (ii) funds
received from the issuance of tax-exempt bonds held in trust for
the construction of various projects or facilities. As of
December 31, 2010 and 2009, we had $146 million and
$306 million, respectively, of restricted trust and escrow
accounts, which are primarily included in long-term “Other
assets” in our Consolidated Balance Sheets. The decrease in
restricted trust and escrow accounts from December 31, 2009
is due to our implementation of revised accounting guidance
related to the consolidation of variable interest entities.
Additional information can be found in Note 2 and
Note 20.
Capping, Closure, Post-Closure and Environmental Remediation
Funds — At several of our landfills, we provide
financial assurance by depositing cash into restricted trust
funds or escrow accounts for purposes of settling capping,
closure, post-closure and environmental remediation obligations.
Balances maintained in these trust funds and escrow accounts
will fluctuate based on (i) changes in statutory
requirements; (ii) future deposits made to comply with
contractual arrangements; (iii) the ongoing use of funds
for qualifying closure, post-closure and environmental
remediation activities; (iv) acquisitions or divestitures
of landfills; and (v) changes in the fair value of the
financial instruments held in the trust fund or escrow accounts.
Tax-Exempt Bond Funds — We obtain funds from
the issuance of industrial revenue bonds for the construction of
collection and disposal facilities and for equipment necessary
to provide waste management services. Proceeds from these
arrangements are directly deposited into trust accounts, and we
do not have the ability to use the funds in regular operating
activities. Accordingly, these borrowings are treated as
non-cash financing activities and are excluded from our
Consolidated Statements of Cash Flows. As our construction and
equipment expenditures are documented and approved by the
applicable bond trustee, the funds are released and we receive a
cash reimbursement. These cash reimbursements are reported in
the Consolidated Statements of Cash Flows as an investing
activity when the cash is released from the trust funds.
Generally, the funds are fully expended within a few years of
the debt issuance. When the debt matures, we repay our
obligation with cash on hand and the debt repayments are
included as a financing activity in the Consolidated Statements
of Cash Flows.
Foreign
Currency
We have operations in Canada. The functional currency of our
Canadian subsidiaries is Canadian dollars. The assets and
liabilities of our foreign operations are translated to
U.S. dollars using the exchange rate at the balance
sheet date. Revenues and expenses are translated to
U.S. dollars using the average exchange rate during the
period. The resulting translation difference is reflected as a
component of comprehensive income.
Derivative
Financial Instruments
We primarily use derivative financial instruments to manage our
risk associated with fluctuations in interest rates, foreign
currency exchange rates and market prices for electricity. We
use interest rate swaps to maintain a strategic portion of our
long-term debt obligations at variable, market-driven interest
rates. In 2009, we entered into interest rate derivatives in
anticipation of senior note issuances planned for 2010 through
2014 to effectively lock in a fixed interest rate for those
anticipated issuances. Foreign currency exchange rate
derivatives are used to hedge our exposure to changes in
exchange rates for anticipated cash transactions between
WM Holdings and its Canadian subsidiaries. We use
electricity commodity derivatives to mitigate the variability in
our revenues and cash flows caused by fluctuations in the market
prices for electricity.
We obtain current valuations of our interest rate, foreign
currency and electricity commodity hedging instruments from
third-party pricing models. The estimated fair values of
derivatives used to hedge risks fluctuate over time and should
be viewed in relation to the underlying hedged transaction and
the overall management of our exposure to fluctuations in the
underlying risks. The fair value of derivatives is included in
other current assets, other long-term assets, accrued
liabilities or other long-term liabilities, as appropriate. Any
ineffectiveness present in either fair value or cash flow hedges
is recognized immediately in earnings without offset. There was
no significant ineffectiveness in 2010, 2009 or 2008.
Insured
and Self-Insured Claims
We have retained a significant portion of the risks related to
our health and welfare, automobile, general liability and
workers’ compensation insurance programs. The exposure for
unpaid claims and associated expenses,
including incurred but not reported losses, generally is
estimated with the assistance of external actuaries and by
factoring in pending claims and historical trends and data. The
gross estimated liability associated with settling unpaid claims
is included in “Accrued liabilities” in our
Consolidated Balance Sheets if expected to be settled within one
year, or otherwise is included in long-term “Other
liabilities.” Estimated insurance recoveries related to
recorded liabilities are reflected as current “Other
receivables” or long-term “Other assets” in our
Consolidated Balance Sheets when we believe that the receipt of
such amounts is probable.
Revenue
Recognition
Our revenues are generated from the fees we charge for waste
collection, transfer, disposal and recycling services and the
sale of recycled commodities, electricity, steam and landfill
gas. The fees charged for our services are generally defined in
our service agreements and vary based on contract-specific terms
such as frequency of service, weight, volume and the general
market factors influencing a region’s rates. The fees we
charge for our services generally include fuel surcharges, which
are intended to pass through to customers increased direct and
indirect costs incurred because of changes in market prices for
fuel. We generally recognize revenue as services are performed
or products are delivered. For example, revenue typically is
recognized as waste is collected, tons are received at our
landfills or transfer stations, recycling commodities are
delivered or as kilowatts are delivered to a customer by a
waste-to-energy
facility or independent power production plant.
We bill for certain services prior to performance. Such services
include, among others, certain residential contracts that are
billed on a quarterly basis and equipment rentals. These advance
billings are included in deferred revenues and recognized as
revenue in the period service is provided.
Capitalized
Interest
We capitalize interest on certain projects under development,
including internal-use software and landfill expansion projects,
and on certain assets under construction, including operating
landfills, landfill
gas-to-energy
projects and
waste-to-energy
facilities. During 2010, 2009 and 2008, total interest costs
were $490 million, $443 million and $472 million,
respectively, of which $17 million in each year was
capitalized. The interest capitalized in 2009 and 2008 was
primarily for landfill construction costs. In 2010, interest was
capitalized primarily for landfill construction costs and
landfill
gas-to-energy
construction projects.
Income
Taxes
The Company is subject to income tax in the United States,
Canada and Puerto Rico. Current tax obligations associated with
our provision for income taxes are reflected in the accompanying
Consolidated Balance Sheets as a component of “Accrued
liabilities,” and the deferred tax obligations are
reflected in “Deferred income taxes.”
Deferred income taxes are based on the difference between the
financial reporting and tax basis of assets and liabilities. The
deferred income tax provision represents the change during the
reporting period in the deferred tax assets and deferred tax
liabilities, net of the effect of acquisitions and dispositions.
Deferred tax assets include tax loss and credit carry-forwards
and are reduced by a valuation allowance if, based on available
evidence, it is more likely than not that some portion or all of
the deferred tax assets will not be realized. Significant
judgment is required in assessing the timing and amounts of
deductible and taxable items. We establish reserves for
uncertain tax positions when, despite our belief that our tax
return positions are fully supportable, we believe that certain
positions may be challenged and potentially disallowed. When
facts and circumstances change, we adjust these reserves through
our provision for income taxes.
To the extent interest and penalties may be assessed by taxing
authorities on any underpayment of income tax, such amounts have
been accrued and are classified as a component of income tax
expense in our Consolidated Statements of Operations.
Contingent
Liabilities
We estimate the amount of potential exposure we may have with
respect to claims, assessments and litigation in accordance with
accounting principles generally accepted in the United States.
We are party to pending or threatened legal proceedings covering
a wide range of matters in various jurisdictions. It is
difficult to predict the outcome of litigation, as it is subject
to many uncertainties. Additionally, it is not always possible
for management to make a meaningful estimate of the potential
loss or range of loss associated with such contingencies.
Supplemental
Cash Flow Information
Non-cash investing and financing activities are excluded from
the Consolidated Statements of Cash Flows. For the years ended
December 31, 2009 and 2008, non-cash activities included
proceeds from tax-exempt borrowings, net of principal payments
made directly from trust funds, of $105 million and
$169 million, respectively. During the year ended
December 31, 2010, we also had a $215 million non-cash
increase in our debt obligations as a result of the issuance of
a note payable in return for a noncontrolling interest in a
limited liability company established to invest in and manage
low-income housing properties. This investment is discussed in
detail in Note 9.

Landfill and Environmental Remediation Liabilities |
Liabilities for landfill and environmental remediation costs are
presented in the table below (in millions):
The changes to landfill and environmental remediation
liabilities for the years ended December 31, 2009 and 2010
are reflected in the table below (in millions):
Our recorded liabilities as of December 31, 2010 include
the impacts of inflating certain of these costs based on our
expectations for the timing of cash settlement and of
discounting certain of these costs to present value. Anticipated
payments of currently identified environmental remediation
liabilities as measured in current dollars are $43 million
in 2011; $37 million in 2012; $21 million in 2013;
$30 million in 2014; $24 million in 2015; and
$141 million thereafter.
At several of our landfills, we provide financial assurance by
depositing cash into restricted trust funds or escrow accounts
for purposes of settling capping, closure, post-closure and
environmental remediation obligations. Generally, these trust
funds are established to comply with statutory requirements and
operating agreements and we are the sole beneficiary of the
restricted balances. However, certain of the funds have been
established for the benefit of both the Company and the host
community in which we operate.
The fair value of trust funds and escrow accounts for which we
are the sole beneficiary was $124 million at
December 31, 2010 and $231 million as of
December 31, 2009. As discussed in Note 20, effective
January 1, 2010, we deconsolidated the trusts for which
power over significant activities of the trust is shared, which
reduced our restricted trust and escrow accounts by
$109 million as of January 1, 2010. Beginning in 2010,
our interests in these variable interest entities have been
accounted for as investments in unconsolidated entities and
receivables. The fair value of our investment in these entities
was $103 million as of December 31, 2010. These
amounts are included in “Other receivables” and as
long-term “Other assets” in our Consolidated Balance

Goodwill and Other Intangible Assets [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Goodwill and Other Intangible Assets |
Goodwill was $5,726 million as of December 31, 2010
compared with $5,632 million as of December 31, 2009.
The $94 million increase in our goodwill during 2010 was
primarily related to consideration paid for acquisitions in
excess of net assets acquired of $77 million and accounting
for foreign currency translation.
We incurred no impairment of goodwill as a result of our annual,
fourth quarter goodwill impairment tests in 2010, 2009 or 2008.
Additionally, we did not encounter any events or changes in
circumstances that indicated that an impairment was more likely
than not during interim periods in 2010, 2009 or 2008. However,
there can be no assurance that goodwill will not be impaired at
any time in the future.
Our other intangible assets as of December 31, 2010 and
2009 were comprised of the following (in millions):
Amortization expense for other intangible assets was
$41 million for 2010, $29 million for 2009, and
$24 million for 2008. At December 31, 2010, we had
$41 million of intangible assets that are not subject to
amortization, which are primarily operating permits that do not
have stated expirations or that have routine,
administrative renewal processes. Additional information related
to intangible assets acquired through 2010 business combinations
is included in Note 19. As of December 31, 2010,
expected annual amortization expense related to intangible
assets is $43 million in 2011; $39 million in 2012;
$34 million in 2013; $26 million in 2014; and
$22 million in 2015.

Debt [Abstract] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Debt |
The following table summarizes the major components of debt at
December 31 (in millions) and provides the maturities and
interest rates of each major category as of December 31:
Debt
Classification
As of December 31, 2010, we had (i) $502 million
of debt maturing within twelve months, including
U.S.$212 million under our Canadian credit facility and
$147 million of 7.65% senior notes that mature in
March 2011; and (ii) $405 million of fixed-rate
tax-exempt borrowings subject to re-pricing within the next
twelve months. Under accounting principles generally accepted in
the United States, this debt must be classified as current
unless we have the intent and ability to refinance it on a
long-term basis. We have the intent and ability to refinance
$674 million of this debt on a long-term basis. We have
classified the remaining $233 million as current
obligations as of December 31, 2010.
As of December 31, 2010, we also have $565 million of
variable-rate tax-exempt bonds and $46 million of
variable-rate tax-exempt project bonds. The interest rates on
these bonds are reset on either a daily or weekly basis through
a remarketing process. If the remarketing agent is unable to
remarket the bonds, the remarketing agent can put the bonds to
us. These bonds are supported by letters of credit guaranteeing
repayment of the bonds in this event. We classified these
borrowings as long-term in our Consolidated Balance Sheet at
December 31, 2010 because the borrowings are supported by
letters of credit issued under our three-year, $2.0 billion
revolving credit facility, which is long-term.
Access
to and Utilization of Credit Facilities
Revolving Credit Facility — In June 2010, we
entered into a three-year, $2.0 billion revolving credit
facility, replacing the $2.4 billion credit facility that
would have matured in August 2011. This facility provides us
with credit capacity to be used for either cash borrowings or to
support letters of credit. At December 31, 2010, we had no
outstanding borrowings and $1,138 million of letters of
credit issued and supported by the facility. The unused and
available credit capacity of the facility was $862 million
as of December 31, 2010.
Letter of Credit Facilities — As of
December 31, 2010, we had an aggregate committed capacity
of $505 million under letter of credit facilities with
maturities that extend from June 2013 to June 2015. These
facilities are currently being used to back letters of credit
issued to support our bonding and financial assurance needs. Our
letters of credit generally have terms providing for automatic
renewal after one year. In the event of an unreimbursed draw on
a letter of credit, the amount of the draw paid by the letter of
credit provider generally converts into a term loan for the
remaining term of the respective facility. Through
December 31, 2010, we had not experienced any unreimbursed
draws on letters of credit under these facilities. As of
December 31, 2010, no borrowings were outstanding under
these letter of credit facilities and we had no unused or
available credit capacity.
Canadian Credit Facility — In November 2005,
Waste Management of Canada Corporation, one of our wholly-owned
subsidiaries, entered into a credit facility agreement to
facilitate WM’s repatriation of accumulated earnings and
capital from its Canadian subsidiaries. As of December 31,
2010, the agreement provides available credit capacity of up to
C$340 million and matures in November 2012.
As of December 31, 2010, we had U.S.$216 million of
principal (U.S.$212 million net of discount) outstanding
under this credit facility. The proceeds we initially received
represented the net present value of the principal amount of the
advances based on the term outstanding, and the debt was
initially recorded based on the net proceeds received. The
advances have a weighted average effective interest rate of 2.2%
at December 31, 2010, which is being amortized to interest
expense with a corresponding increase in our recorded debt
obligation using the effective interest method. During the year
ended December 31, 2010, we increased the carrying value of
the debt for the recognition of U.S.$3 million of interest
expense. A total of U.S.$56 million of net advances under
the facility matured during 2010 and were repaid with available
cash. Accounting for changes in the Canadian currency
translation rate increased the carrying value of these
borrowings by U.S.$10 million during 2010.
Debt
Borrowings and Repayments
The significant changes in our debt balances from
December 31, 2009 to December 31, 2010 are related to
the following:
Senior Notes — In June 2010, we issued
$600 million of 4.75% senior notes due June 2020. The
net proceeds from the debt issuance were $592 million. We
used the proceeds together with cash on hand to repay
$600 million of 7.375% senior notes that matured in
August 2010.
The remaining change in the carrying value of our senior notes
from December 31, 2009 to December 31, 2010 is
principally due to accounting for our
fixed-to-floating
interest rate swap agreements, which are accounted for as fair
value hedges resulting in all fair value adjustments being
reflected as a component of the carrying value of the underlying
debt. For additional information regarding our interest rate
derivatives, refer to Note 8.
Tax-Exempt Bonds — Tax-exempt bonds are used as
a means of accessing low-cost financing for capital
expenditures. The proceeds from these debt issuances may only be
used for the specific purpose for which the money was raised,
which is generally to finance expenditures for landfill
construction and development, equipment, vehicles and facilities
in support of our operations. Proceeds from bond issues are held
in trust until such time as we incur qualified expenditures, at
which time we are reimbursed from the trust funds. During the
year ended December 31, 2010, $52 million of our
tax-exempt bonds were repaid with available cash.
Tax-Exempt Project Bonds — Tax-exempt project
bonds have been used by our Wheelabrator Group to finance the
development of
waste-to-energy
facilities. These facilities are integral to the local
communities they serve, and, as such, are supported by long-term
contracts with multiple municipalities. The bonds generally have
periodic amortizations that are supported by the cash flow of
each specific facility being financed. During the year ended
December 31, 2010, we repaid $39 million of our
tax-exempt project bonds with available cash.
Capital Leases and Other — The significant
increase in our capital leases and other debt obligations in
2010 is primarily related to our federal low-income housing
investment discussed in Note 9, which increased our debt
obligations by $215 million. This increase was offset by
$49 million of repayments of various borrowings at their
scheduled maturities.
Scheduled Debt and Capital Lease Payments —
Scheduled debt and capital lease payments for the next five
years are as follows: $511 million in 2011; $614 million in
2012; $203 million in 2013; $459 million in 2014; and
$452 million in 2015. Our recorded debt and capital lease
obligations include non-cash adjustments associated with
discounts, premiums and fair value adjustments for interest rate
hedging activities, which have been excluded from these amounts
because they will not result in cash payments.
Secured
Debt
Our debt balances are generally unsecured, except for
$30 million of the tax-exempt project bonds outstanding at
December 31, 2010 that were issued by certain subsidiaries
within our Wheelabrator Group. These bonds are secured by the
related subsidiaries’ assets, which have a carrying value
of $295 million, and the related subsidiaries’ future
revenue.
Debt
Covenants
Our revolving credit facility and certain other financing
agreements contain financial covenants. The most restrictive of
these financial covenants are contained in our revolving credit
facility. The following table summarizes the requirements of
these financial covenants, as defined by the revolving credit
facility:
Our revolving credit facility and senior notes also contain
certain restrictions intended to monitor our level of
indebtedness, types of investments and net worth. We monitor our
compliance with these restrictions, but do not believe that they
significantly impact our ability to enter into investing or
financing arrangements typical for our business. As of
December 31, 2010 and December 31, 2009, we were in
compliance with the covenants and restrictions under all of our
debt agreements.

Derivative Instruments and Hedging Activities |
The following table summarizes the fair values of derivative
instruments recorded in our Consolidated Balance Sheet as of
December 31 (in millions):
For information related to the methods used to measure our
derivative assets and liabilities at fair value, refer to
Note 18.
Interest
Rate Derivatives
Interest
Rate Swaps
We use interest rate swaps to maintain a portion of our debt
obligations at variable market interest rates. As of
December 31, 2010, we had approximately $5.4 billion
in fixed-rate senior notes outstanding. The interest payments on
$500 million, or 9%, of these senior notes have been
swapped to variable interest rates to protect the debt against
changes in fair value due to changes in benchmark interest
rates. As of December 31, 2009, we had approximately
$5.4 billion in fixed-rate senior notes outstanding, of
which $1.1 billion, or 20%, had been swapped to variable
interest rates. The significant terms of our interest rate swap
agreements as of December 31, 2010 and 2009 are summarized
in the table below (in millions):
The decrease in the notional amount of our interest rate swaps
from December 31, 2009 to December 31, 2010 was due to
the scheduled maturity of interest rate swaps with a notional
amount of $600 million in August 2010.
We have designated our interest rate swaps as fair value hedges
of our fixed-rate senior notes. Fair value hedge accounting for
interest rate swap contracts increased the carrying value of
debt instruments by $79 million as of December 31,
2010 and $91 million as of December 31, 2009. The
following table summarizes the fair value adjustments from
interest rate swap agreements at December 31 (in millions):
Gains or losses on the derivatives as well as the offsetting
losses or gains on the hedged items attributable to our interest
rate swaps are recognized in current earnings. We include gains
and losses on our interest rate swaps as adjustments to interest
expense, which is the same financial statement line item where
offsetting gains and losses on the related hedged items are
recorded. The following table summarizes the impact of changes
in the fair value of our interest rate swaps and the underlying
hedged items on our results of operations (in millions):
We also recognize the impacts of (i) net periodic
settlements of current interest on our active interest rate
swaps and (ii) the amortization of previously terminated
interest rate swap agreements as adjustments to interest
expense.
The following table summarizes the impact of periodic
settlements of active swap agreements and the impact of
terminated swap agreements on our results of operations (in
millions):
Treasury
Rate Locks
During the third quarter of 2009, we entered into Treasury rate
locks with a total notional amount of $200 million to hedge
the risk of changes in semi-annual interest payments for a
portion of the senior notes that the Company planned to issue in
June 2010. The Treasury rate locks were terminated in the second
quarter of 2010 contemporaneously with the actual issuance of
senior notes, and we paid cash of $7 million upon
settlement. In 2009, we recognized pre-tax and after-tax gains
of $4 million and $2 million, respectively, to other
comprehensive income for changes in the fair value of these
Treasury rate locks. In 2010, we recognized pre-tax and
after-tax losses of $11 million and $7 million,
respectively, to other comprehensive income for changes in the
fair value of these Treasury rate locks. There was no
significant ineffectiveness associated with these hedges during
2009 or 2010.
At December 31, 2010 and 2009, our “Accumulated other
comprehensive income” included $16 million and
$14 million, respectively, of deferred losses, net of taxes
associated with the Treasury rate locks mentioned above and with
Treasury rate locks that had been executed in previous years in
anticipation of senior note issuances. These deferred losses are
reclassified to interest expense over the life of the related
senior note issuances, which extend through 2032. Pre-tax
amounts of $8 million, $9 million and $6 million
were reclassified out of accumulated other comprehensive income
and into interest expense in 2010, 2009 and 2008, respectively.
As of December 31, 2010, $7 million (on a pre-tax
basis) is scheduled to be reclassified into interest expense
over the next twelve months.
Forward-Starting
Interest Rate Swaps
The Company currently expects to issue fixed-rate debt in March
2011, November 2012 and March 2014 and has executed
forward-starting interest rate swaps for these anticipated debt
issuances with notional amounts of $150 million,
$200 million and $175 million, respectively. We
entered into the forward-starting interest rate swaps during the
fourth quarter of 2009 to hedge the risk of changes in the
anticipated semi-annual interest payments due to fluctuations in
the forward ten-year LIBOR swap rate. Each of the
forward-starting swaps has an effective date of the anticipated
date of debt issuance and a tenor of ten years.
We have designated our forward-starting interest rate swaps as
cash flow hedges. As of December 31, 2010, the fair value
of these interest rate derivatives is comprised of
$11 million of current liabilities and $13 million of
long-term liabilities. We recognized pre-tax and after-tax
losses of $33 million and $20 million, respectively,
to other comprehensive income for changes in the fair value of
our forward-starting interest rate swaps during the year ended
December 31, 2010. There was no ineffectiveness associated
with these hedges during the year ended December 31,
2010. The reclassification of deferred losses into earnings will
begin when related forecasted senior note issuances occur and
will continue over the life of the related senior note
issuances, which are expected to extend through 2024.
As of December 31, 2009, the fair value of these interest
rate derivatives was comprised of $9 million of long-term
assets. We recognized pre-tax and after-tax gains of
$9 million and $5 million, respectively, to other
comprehensive income for changes in the fair value of our
forward-starting interest rate swaps during the year ended
December 31, 2009. There was no ineffectiveness associated
with these hedges during the year ended December 31, 2009.
Credit-Risk
Features
Certain of our interest rate derivative instruments contain
provisions related to the Company’s credit rating. If the
Company’s credit rating were to fall to specified levels
below investment grade, the counterparties have the ability to
terminate the derivative agreements, resulting in immediate
settlement of all affected transactions. As of December 31,
2010, we had not experienced any credit events that would
trigger these provisions. The net liabilities of our derivative
instruments with credit-risk-related features were immaterial as
of December 31, 2010.
Foreign
Exchange Derivatives
We use foreign currency exchange rate derivatives to hedge our
exposure to changes in exchange rates for anticipated
intercompany cash transactions between WM Holdings and its
Canadian subsidiaries. We had foreign currency forward contracts
outstanding as of December 31, 2010 and 2009 for
anticipated cash flows associated with outstanding debt
arrangements with these wholly-owned subsidiaries.
As of December 31, 2009, the hedged cash flows included
C$370 million of principal payments and C$22 million
of interest payments scheduled for December 31, 2010. The
intercompany note and related forward contracts matured as
scheduled in December 2010 and we paid cash of $37 million
to settle the forward contracts.
In December 2010, we also executed a new C$370 million
intercompany debt arrangement and entered into new forward
contracts for the related principal and interest cash flows. The
total notional value of the forward contracts is
C$401 million. Scheduled interest payments are as follows:
C$10 million on November 30, 2011, C$11 million
on November 30, 2012 and C$10 million on
October 31, 2013. The principal is scheduled to be repaid
on October 31, 2013. We designated these forward contracts
as cash flow hedges.
Gains or losses on the underlying hedged items attributable to
foreign currency exchange risk are recognized in current
earnings. We include gains and losses on our foreign currency
forward contracts as adjustments to other income and expense,
which is the same financial statement line item where offsetting
gains and losses on the related hedged items are recorded. The
following table summarizes the pre-tax impacts of our foreign
currency cash flow derivatives on our results of operations and
comprehensive income (in millions):
Amounts reported in other comprehensive income and accumulated
other comprehensive income are reported net of tax. Adjustments
to other comprehensive income for changes in the fair value of
our foreign currency cash flow hedges resulted in the
recognition of an after tax-loss of $14 million during the
year ended December 31, 2010; an after-tax loss of
$28 million during the year ended December 31, 2009;
and an after-tax gain of $40 million during the year ended
December 31, 2008. Adjustments for the reclassification of
gains or (losses) from accumulated other comprehensive income
into income were $(11) million during the year ended
December 31, 2010; $(28) million during the year ended
December 31, 2009; $44 million during the year ended
December 31,
2008. Ineffectiveness has been included in other income and
expense during each of the reported periods. There was no
significant ineffectiveness associated with these hedges during
the years ended December 31, 2010, 2009 or 2008.
Electricity
Commodity Derivatives
As a result of the expiration of certain long-term, above-market
electricity contracts at our
waste-to-energy
facilities, we use short-term “receive fixed, pay
variable” electricity commodity swaps to mitigate the
variability in our revenues and cash flows caused by
fluctuations in the market prices for electricity. The swaps
executed in 2010 hedged 672,360 megawatt hours, or approximately
26%, of our Wheelabrator Group’s 2010 merchant electricity
sales and are expected to hedge about 1 million megawatt
hours, or 33%, of the Group’s 2011 merchant electricity
sales. There was no significant ineffectiveness associated with
these cash flow hedges during 2010. All financial statement
impacts associated with these derivatives were immaterial for
the year ended December 31, 2010.

Income Taxes |
Provision
for Income Taxes
Our “Provision for income taxes” consisted of the
following (in millions):
The U.S. federal statutory income tax rate is reconciled to
the effective rate as follows:
The comparability of our income taxes for the reported periods
has been primarily affected by variations in our income before
income taxes, tax audit settlements, changes in effective state
and Canadian statutory tax rates, realization of state net
operating loss and credit carry-forwards, utilization of a
capital loss carry-back and miscellaneous federal tax credits.
For financial reporting purposes, income before income taxes
showing domestic and foreign sources was as follows (in
millions) for the years ended December 31, 2010, 2009 and
2008:
Tax Audit Settlements — The Company and its
subsidiaries file income tax returns in the United States,
Canada and Puerto Rico, as well as various state and local
jurisdictions. We are currently under audit by the IRS and from
time to time we are audited by other taxing authorities. Our
audits are in various stages of completion.
In the fourth quarter of 2010, we effectively settled an IRS
audit for the 2009 tax year as well as various state tax audits.
In addition, during the third quarter of 2010, we finalized
audits in Canada through 2005. The settlement of these tax
audits resulted in a reduction to our “Provision for income
taxes” of $8 million, or $0.02 per diluted share, for
the year ended December 31, 2010.
During 2009, we settled the IRS audit for the 2008 tax year as
well as various state tax audits. The settlement of these tax
audits resulted in a reduction to our “Provision for income
taxes” of $11 million, or $0.02 per diluted share, for
the year ended December 31, 2009.
During 2008, we settled IRS audits for the 2006 and 2007 tax
years as well as various state tax audits. In addition, we
settled the majority of the issues with respect to Canadian
audits for the tax years 2002 through 2005. The settlement of
these tax audits resulted in a reduction to our “Provision
for income taxes” of $26 million, or $0.05 per diluted
share, for the year ended December 31, 2008.
We are currently in the examination phase of IRS audits for the
tax years 2010 and 2011 and expect these audits to be completed
within the next 12 and 24 months, respectively. We
participate in the IRS’s Compliance Assurance Program,
which means we work with the IRS throughout the year in order to
resolve any material issues prior to the filing of our year-end
tax return. We are also currently undergoing audits by various
state and local jurisdictions that date back to 2000. In the
third quarter of 2010, we finalized audits in Canada through the
2005 tax year and are not currently under audit for any
subsequent tax years.
Effective State Tax Rate Change — During 2010,
our current state tax rate increased from 6.25% to 6.75%
resulting in an increase to our provision for income taxes of
$5 million. In addition, our state deferred income taxes
increased $37 million to reflect the impact of changes in
the estimated tax rate at which existing temporary differences
will be realized. During 2009, our current state tax rate
increased from 6.0% to 6.25% and our deferred state tax rate
increased from 5.5% to 5.75%, resulting in an increase to our
income taxes of $3 million and $6 million,
respectively. During 2008, our current state tax rate increased
from 5.5% to 6.0%, resulting in an increase to our income taxes
of $5 million. The increases in these rates are primarily
due to changes in state law. The comparison of our effective
state tax rate during the reported periods has also been
affected by
return-to-accrual
adjustments, which increased our “Provision for income
taxes” in 2010 and reduced our “Provision for income
taxes” in 2009 and 2008.
Canada Statutory Tax Rate Change — During 2009,
the provincial tax rates in Ontario were reduced, which resulted
in a $13 million tax benefit as a result of the revaluation
of the related deferred tax balances.
State Net Operating Loss and Credit
Carry-Forwards — During 2010, 2009, and 2008, we
released state net operating loss and credit carry-forwards
resulting in a reduction to our “Provision for income
taxes” for those periods of $4 million,
$35 million and $3 million, respectively.
Capital Loss Carry-Back — During 2009, we
generated a capital loss from the liquidation of a foreign
subsidiary. We determined that the capital loss could be
utilized to offset capital gains from 2006 and 2007, which
resulted in a reduction to our 2009 “Provision for income
taxes” of $65 million.
Federal Low-income Housing Tax Credits — In
April 2010, we acquired a noncontrolling interest in a limited
liability company established to invest in and manage low-income
housing properties. Our consideration for this investment
totaled $221 million, which was comprised of a
$215 million note payable and an initial cash payment of
$6 million. The entity’s low-income housing
investments qualify for federal tax credits that are expected to
be realized through 2020 in accordance with Section 42 of
the Internal Revenue Code.
We account for our investment in this entity using the equity
method of accounting, and we recognize a charge to “Equity
in net losses of unconsolidated entities,” within our
Consolidated Statement of Operations, for reductions in the
value of our investment. The value of our investment decreases
as the tax credits are generated and utilized. During the year
ended December 31, 2010, we recognized a total of
$19 million of losses for reductions in the value of our
investment. We also recognized $5 million of interest
expense related to this investment during 2010. However, our tax
provision for the year ended December 31, 2010 was reduced
by $26 million (including $16 million of tax credits)
as a result of this investment, which more than offset the
pre-tax expense realized during the period.
Unremitted Earnings in Foreign Subsidiaries —
At December 31, 2010, remaining unremitted earnings in
foreign operations were approximately $644 million, which
are considered permanently invested and, therefore, no provision
for U.S. income taxes has been accrued for these unremitted
earnings.
Deferred
Tax Assets (Liabilities)
The components of the net deferred tax assets (liabilities) at
December 31 are as follows (in millions):
At December 31, 2010, we had $27 million of federal
net operating loss, or NOL, carry-forwards and $1.3 billion
of state NOL carry-forwards. The federal and state NOL
carry-forwards have expiration dates through the year 2030. We
also have a $76 million capital loss carry-forward that
expires in 2014. In addition, we have $39 million of state
tax credit carry-forwards at December 31, 2010.
We have established valuation allowances for uncertainties in
realizing the benefit of certain tax loss and credit
carry-forwards and other deferred tax assets. While we expect to
realize the deferred tax assets, net of the valuation
allowances, changes in estimates of future taxable income or in
tax laws may alter this expectation. The valuation allowance
decreased $7 million in 2010 due to changes in our gross
deferred tax assets due to changes in state NOL and credit
carry-forwards.
Liabilities
for Uncertain Tax Positions
A reconciliation of the beginning and ending amount of gross
unrecognized tax benefits, including accrued interest for 2010,
2009 and 2008 is as follows (in millions):
These liabilities are primarily included as a component of
long-term “Other liabilities” in our Consolidated
Balance Sheets because the Company generally does not anticipate
that settlement of the liabilities will require payment of cash
within the next twelve months. As of December 31, 2010,
$35 million of net unrecognized tax benefits, if recognized
in future periods, would impact our effective tax rate.
We recognize interest expense related to unrecognized tax
benefits in tax expense. During the years ended
December 31, 2010, 2009 and 2008 we recognized
approximately $3 million, $4 million and
$4 million, respectively, of such interest expense as a
component of our “Provision for income taxes.” We had
approximately $8 million and $11 million of accrued
interest in our Consolidated Balance Sheets as of
December 31, 2010 and 2009, respectively. We do not have
any accrued liabilities or expense for penalties related to
unrecognized tax benefits for the years ended December 31,
2010, 2009 and 2008.
We anticipate that approximately $9 million of liabilities
for unrecognized tax benefits, including accrued interest, and
$3 million of related deferred tax assets may be reversed
within the next 12 months. The anticipated reversals are
related to state tax items, none of which are material, and are
expected to result from audit settlements or the expiration of
the applicable statute of limitations period.
Legislation updates — The Small Business
Jobs Act, signed into law in September 2010, contains a tax
incentive package that includes a one-year extension through
2010 of the 50 percent bonus, or accelerated, depreciation
provision first enacted in 2008 and subsequently renewed in
2009. The provision had expired at the end of 2009. Under the
bonus depreciation provision, 50 percent of the basis of
qualified capital expenditures may be deducted in the year the
property is placed in service and the remaining 50 percent
deducted under normal depreciation rules. The acceleration of
deductions on 2010 capital expenditures resulting from the bonus
depreciation provision had no impact on our effective tax rate.
However, the ability to accelerate depreciation deductions did
decrease our 2010 cash taxes by $60 million. Taking the
accelerated tax depreciation will result in increased cash taxes
in future periods when the accelerated deductions for these
capital expenditures would have otherwise been taken.
In addition, new tax law signed on December 17, 2010
includes an extension of the bonus depreciation allowance
through the end of 2011, and increases the amount of qualifying
capital expenditures that can be depreciated immediately from
50 percent to 100 percent. The 100 percent
depreciation deduction applies to qualifying property placed in
service between September 8, 2010 and December 31,
2011.

Employee Benefit Plans [Abstract] | |||||
Employee Benefit Plans |
Defined Contribution Plans — Our Waste
Management retirement savings plans are 401(k) plans that cover
employees, except those working subject to collective bargaining
agreements that do not allow for coverage under such plans.
Employees are generally eligible to participate in the plans
following a
90-day
waiting period after hire
and may contribute as much as 25% of their annual compensation,
subject to annual contribution limitations established by the
IRS. Under our largest retirement savings plan, we match, in
cash, 100% of employee contributions on the first 3% of their
eligible compensation and match 50% of employee contributions on
the next 3% of their eligible compensation, resulting in a
maximum match of 4.5%. Both employee and Company contributions
vest immediately. Charges to “Operating” and
“Selling, general and administrative” expenses for our
defined contribution plans were $55 million in 2010,
$50 million in 2009 and $59 million in 2008.
Defined Benefit Plans — Certain of the
Company’s subsidiaries sponsor pension plans that cover
employees not otherwise covered by the Waste Management
retirement savings plans. These employees are members of
collective bargaining units. In addition, Wheelabrator
Technologies Inc., a wholly-owned subsidiary, sponsors a pension
plan for its former executives and former Board members. As of
December 31, 2010, the combined benefit obligation of these
pension plans was $81 million, and the plans had
$60 million of plan assets, resulting in an unfunded
benefit obligation for these plans of $21 million.
In addition, WM Holdings and certain of its subsidiaries
provided post-retirement health care and other benefits to
eligible employees. In conjunction with our acquisition of
WM Holdings in July 1998, we limited participation in these
plans to participating retired employees as of December 31,
1998. The unfunded benefit obligation for these plans was
$45 million at December 31, 2010.
Our accrued benefit liabilities for our defined benefit pension
and other post-retirement plans are $66 million as of
December 31, 2010 and are included as components of
“Accrued liabilities” and long-term “Other
liabilities” in our Consolidated Balance Sheet.
We are a participating employer in a number of trustee-managed
multiemployer, defined benefit pension plans for employees who
participate in collective bargaining agreements. Contributions
of $35 million in 2010, $34 million in 2009 and
$35 million in 2008 were charged to operations for our
subsidiaries’ ongoing participation in these defined
benefit plans. Our portion of the projected benefit obligation,
plan assets and unfunded liability of the multiemployer pension
plans is not material to our financial position. However, the
failure of participating employers to remain solvent could
affect our portion of the plans’ unfunded liability.
Specific benefit levels provided by union pension plans are not
negotiated with or known by the employer contributors.
In connection with our ongoing renegotiations of various
collective bargaining agreements, we may discuss and negotiate
for the complete or partial withdrawal from one or more of these
pension plans. If we elect to withdraw from these plans, we may
incur expenses associated with our obligations for unfunded
vested benefits at the time of the withdrawal. As discussed in
Note 11, in 2010, 2009 and 2008, we recognized aggregate
charges of $26 million, $9 million and
$39 million, respectively, to “Operating”
expenses for the withdrawal of certain bargaining units from
multiemployer pension plans.

Commitments and Contingencies |
Financial Instruments — We have obtained
letters of credit, performance bonds and insurance policies and
have established trust funds and issued financial guarantees to
support tax-exempt bonds, contracts, performance of landfill
capping, closure and post-closure requirements, environmental
remediation, and other obligations. Letters of credit generally
are supported by our revolving credit facility and other credit
facilities established for that purpose. These facilities are
discussed further in Note 7. We obtain surety bonds and
insurance policies from an entity in which we have a
noncontrolling financial interest. We also obtain insurance from
a wholly-owned insurance company, the sole business of which is
to issue policies for us. In those instances where our use of
financial assurance from entities we own or have financial
interests in is not allowed, we have available alternative
financial assurance mechanisms.
Management does not expect that any claims against or draws on
these instruments would have a material adverse effect on our
consolidated financial statements. We have not experienced any
unmanageable difficulty in obtaining the required financial
assurance instruments for our current operations. In an ongoing
effort to mitigate
risks of future cost increases and reductions in available
capacity, we continue to evaluate various options to access
cost-effective sources of financial assurance.
Insurance — We carry insurance coverage for
protection of our assets and operations from certain risks
including automobile liability, general liability, real and
personal property, workers’ compensation, directors’
and officers’ liability, pollution legal liability and
other coverages we believe are customary to the industry. Our
exposure to loss for insurance claims is generally limited to
the per incident deductible under the related insurance policy.
Our exposure, however, could increase if our insurers are unable
to meet their commitments on a timely basis.
We have retained a significant portion of the risks related to
our automobile, general liability and workers’ compensation
insurance programs. For our self-insured retentions, the
exposure for unpaid claims and associated expenses, including
incurred but not reported losses, is based on an actuarial
valuation and internal estimates. The accruals for these
liabilities could be revised if future occurrences or loss
development significantly differ from our assumptions used. As
of December 31, 2010, our general liability insurance
program carried self-insurance exposures of up to
$2.5 million per incident and our workers’
compensation insurance program carried self-insurance exposures
of up to $5 million per incident. As of December 31,
2010, our auto liability insurance program included a
per-incident base deductible of $5 million, subject to
additional deductibles of $4.8 million in the
$5 million to $10 million layer. Self-insurance claims
reserves acquired as part of our acquisition of WM Holdings
in July 1998 were discounted at 3.50% at December 31, 2010,
3.75% at December 31, 2009 and 2.25% at December 31,
2008. The changes to our net insurance liabilities for the three
years ended December 31, 2010 are summarized below (in
millions):
The Directors’ and Officers’ Liability Insurance
policy we choose to maintain covers only individual executive
liability, often referred to as “Broad Form Side A,”
and does not provide corporate reimbursement coverage, often
referred to as “Side B.” The Side A policy covers
directors and officers directly for loss, including defense
costs, when corporate indemnification is unavailable. Side
A-only coverage cannot be exhausted by payments to the Company,
as the Company is not insured for any money it advances for
defense costs or pays as indemnity to the insured directors and
officers.
We do not expect the impact of any known casualty, property,
environmental or other contingency to have a material impact on
our financial condition, results of operations or cash flows.
Operating Leases — Rental expense for leased
properties was $121 million during 2010 and
$114 million during both 2009 and 2008. Minimum contractual
payments due for our operating lease obligations are
$82 million in 2011, $76 million in 2012,
$62 million in 2013, $51 million in 2014 and
$40 million in 2015.
Our minimum contractual payments for lease agreements during
future periods is significantly less than current year rent
expense due to short-term leases and because our significant
lease agreements at landfills have variable terms based either
on a percentage of revenue or a rate per ton of waste received.
Other
Commitments
Our unconditional obligations are established in the ordinary
course of our business and are structured in a manner that
provides us with access to important resources at competitive,
market-driven rates. Our actual future obligations under these
outstanding agreements are generally quantity driven, and, as a
result, our associated financial obligations are not fixed as of
December 31, 2010. For these contracts, we have estimated
our future obligations based on the current market values of the
underlying products or services. Our estimated minimum
obligations for the above-described purchase obligations are
$85 million in 2011, $84 million in 2012,
$58 million in 2013, $21 million in 2014 and
$16 million in 2015. We currently expect the products and
services provided by these agreements to continue to meet the
needs of our ongoing operations. Therefore, we do not expect
these established arrangements to materially impact our future
financial position, results of operations or cash flows.
Guarantees — We have entered into the following
guarantee agreements associated with our operations:
We currently do not believe it is reasonably likely that we
would be called upon to perform under these guarantees and do
not believe that any of the obligations would have a material
effect on our financial position, results of operations or cash
flows.
Environmental Matters — A significant portion
of our operating costs and capital expenditures could be
characterized as costs of environmental protection, as we are
subject to an array of laws and regulations relating to the
protection of the environment. Under current laws and
regulations, we may have liabilities for environmental damage
caused by our operations, or for damage caused by conditions
that existed before we acquired a site. In addition to
remediation activity required by state or local authorities,
such liabilities include PRP investigations.
The costs associated with these liabilities can include
settlements, certain legal and consultant fees, as well as
incremental internal and external costs directly associated with
site investigation and
clean-up.
Estimating our degree of responsibility for remediation is
inherently difficult. We recognize and accrue for an estimated
remediation liability when we determine that such liability is
both probable and reasonably estimable. Determining the method
and ultimate cost of remediation requires that a number of
assumptions be made. There can sometimes be a range of
reasonable estimates of the costs associated with the
investigation of the extent of environmental impact and
identification of likely site-remediation alternatives. In these
cases, we use the amount within the range that constitutes our
best estimate. If no amount within a range appears to be a
better estimate than any other, we use the amount that is the
low end of such range. If we used the high ends of such ranges,
our aggregate potential liability would be approximately
$150 million higher than the $284 million recorded in
the Consolidated Financial Statements as of December 31,
2010. Our ongoing review of our remediation liabilities, in
light of relevant internal and external facts and circumstances,
could result in revisions to our accruals that could cause
upward or downward adjustments to income from operations. These
adjustments could be material in any given period.
As of December 31, 2010, we had been notified that we are a
PRP in connection with 75 locations listed on the EPA’s
National Priorities List, or NPL. Of the 75 sites at which
claims have been made against us, 17 are sites we own. Each of
the NPL sites we own was initially developed by others as a
landfill disposal facility. At each of these facilities, we are
working in conjunction with the government to characterize or
remediate identified site problems, and we have either agreed
with other legally liable parties on an arrangement for sharing
the costs of remediation or are working toward a cost-sharing
agreement. We generally expect to receive any amounts due from
other participating parties at or near the time that we make the
remedial expenditures. The other 58 NPL sites, which we do not
own, are at various procedural stages under the Comprehensive
Environmental Response, Compensation and Liability Act of 1980,
as amended, known as CERCLA or Superfund.
The majority of these proceedings involve allegations that
certain of our subsidiaries (or their predecessors) transported
hazardous substances to the sites, often prior to our
acquisition of these subsidiaries. CERCLA generally provides for
liability for those parties owning, operating, transporting to
or disposing at the sites. Proceedings arising under Superfund
typically involve numerous waste generators and other waste
transportation and disposal companies and seek to allocate or
recover costs associated with site investigation and
remediation, which costs could be substantial and could have a
material adverse effect on our consolidated financial
statements. At some of the sites at which we have been
identified as a PRP, our liability is well defined as a
consequence of a governmental decision and an agreement among
liable parties as to the share each will pay for implementing
that remedy. At other sites, where no remedy has been selected
or the liable parties have been unable to agree on an
appropriate allocation, our future costs are uncertain.
Litigation — In April 2002, two former
participants in the ERISA plans of WM Holdings filed a
lawsuit in the U.S. District Court for the District of
Columbia in a case entitled William S. Harris, et al. v.
James E. Koenig, et al. The lawsuit named as defendants
WM Holdings; the members of WM Holdings’ Board of
Directors prior to July 1998; the administrative and investment
committees of WM Holdings’ ERISA plans and their
individual members; WM’s retirement savings plan; the
investment committees of WM’s plan and its individual
members; and State Street Bank & Trust, the trustee
and investment manager of the ERISA plans. The lawsuit attempts
to increase the recovery of a class of ERISA plan participants
based on allegations related to both the events alleged in, and
the settlements relating to, the securities class action against
WM Holdings that was settled in 1998 and the securities
class action against WM that was settled in 2001. During the
second quarter of 2010, the Court dismissed certain claims
against individual defendants, including all claims against each
of the current members of our Board of Directors.
Mr. Simpson, our Chief Financial Officer, is a named
defendant in these actions by virtue of his membership on the WM
ERISA plan Investment Committee at that time. Recently,
plaintiffs dismissed all claims related to the settlement of the
securities class action against WM that was settled in 2001, and
the court certified a limited class of participants who may
bring claims on behalf of the plan, but not individually. All of
the remaining defendants intend to continue to defend themselves
vigorously.
Two separate wage and hour lawsuits were commenced in October
2006 and March 2007, respectively, that are pending against
certain of our subsidiaries in California, each seeking class
certification. The actions were coordinated to proceed in
San Diego County Superior Court. Both lawsuits make the
same general allegations that the defendants failed to comply
with certain California wage and hour laws, including allegedly
failing to provide meal and rest periods and failing to properly
pay hourly and overtime wages. We have executed a settlement
agreement in connection with this matter; however, such
settlement remains subject to final court approval and other
contingencies.
Additionally, in July 2008, we were named as a defendant in a
purported class action in the Circuit Court of Bullock County,
Alabama, which was subsequently removed to the United States
District Court for the Northern District of Alabama. This suit
pertains to our fuel and environmental charge and generally
alleges that such charges were not properly disclosed, were
unfair, and were contrary to contract. We filed a motion to
dismiss that was partially granted during the third quarter of
2010, resulting in dismissal of the plaintiffs’ RICO and
national class action claims. We deny the claims in all of these
actions and intend to continue to oppose class certification and
will vigorously defend these matters. Given the inherent
uncertainties of litigation, the ultimate outcome of these cases
cannot be predicted at this time, nor can possible damages, if
any, be reasonably estimated.
From time to time, we also are named as defendants in personal
injury and property damage lawsuits, including purported class
actions, on the basis of having owned, operated or transported
waste to a disposal facility that is alleged to have
contaminated the environment or, in certain cases, on the basis
of having conducted environmental remediation activities at
sites. Some of the lawsuits may seek to have us pay the costs of
monitoring of allegedly affected sites and health care
examinations of allegedly affected persons for a substantial
period of time even where no actual damage is proven. While we
believe we have meritorious defenses to these lawsuits, the
ultimate resolution is often substantially uncertain due to the
difficulty of determining the cause, extent and impact of
alleged contamination (which may have occurred over a long
period of time), the potential for successive groups of
complainants to emerge, the diversity of the individual
plaintiffs’ circumstances, and the potential contribution
or indemnification obligations of co-defendants or other third
parties, among other factors.
As a large company with operations across the United States and
Canada, we are subject to various proceedings, lawsuits,
disputes and claims arising in the ordinary course of our
business. Many of these actions raise complex factual and legal
issues and are subject to uncertainties. Actions filed against
us include commercial, customer, and employment-related claims,
including, as noted above, purported class action lawsuits
related to our customer service agreements and purported class
actions involving federal and state wage and hour and other
laws. The plaintiffs in some actions seek unspecified damages or
injunctive relief, or both. These actions are in various
procedural stages, and some are covered in part by insurance. We
currently do not believe that any such actions will ultimately
have a material adverse impact on our consolidated financial
statements.
WM’s charter and bylaws require indemnification of its
officers and directors if statutory standards of conduct have
been met and allow the advancement of expenses to these
individuals upon receipt of an undertaking by the individuals to
repay all expenses if it is ultimately determined that they did
not meet the required standards of conduct. Additionally, WM has
entered into separate indemnification agreements with each of
the members of its Board of Directors as well as its President
and Chief Executive Officer, and its Chief Financial Officer.
The Company may incur substantial expenses in connection with
the fulfillment of its advancement of costs and indemnification
obligations in connection with current actions involving former
officers of the Company or its subsidiaries or other actions or
proceedings that may be brought against its former or current
officers, directors and employees.
Item 103 of the SEC’s
Regulation S-K
requires disclosure of certain environmental matters when a
governmental authority is a party to the proceedings, or such
proceedings are known to be contemplated, unless we reasonably
believe that the matter will result in no monetary sanctions, or
in monetary sanctions, exclusive of
interest and costs, of less than $100,000. The following matters
pending as of December 31, 2010 are disclosed in accordance
with that requirement:
On April 4, 2006, the EPA issued a Notice of Violation
(“NOV”) to Waste Management of Hawaii, Inc., an
indirect wholly-owned subsidiary of WM, and to the City and
County of Honolulu for alleged violations of the federal Clean
Air Act, based on alleged failure to submit certain reports and
design plans required by the EPA, and the failure to begin and
timely complete the installation of a gas collection and control
system (“GCCS”) for the Waimanalo Gulch Sanitary
Landfill on Oahu. The EPA has also indicated that it will seek
penalties and injunctive relief as part of the NOV enforcement
for elevated landfill temperatures that were recorded after
installation of the GCCS. The parties have been in confidential
settlement negotiations. Pursuant to an indemnity agreement, any
penalty assessed will be paid by the Company, and not by the
City and County of Honolulu.
The Massachusetts Attorney General’s Office has commenced
investigations into allegations of violations of the Clean Air
Act, the Clean Water Act, solid waste regulations and permits at
Wheelabrator Group facilities in Saugus and North Andover,
Massachusetts. The Attorney General’s Office is also
considering intervening in two private lawsuits alleging
potential claims under the Massachusetts False Claims Act. No
formal enforcement action has been brought against the Company,
although we potentially could be subject to sanctions, including
requirements to pay monetary penalties. We are cooperating with
the Attorney General’s office in the investigations.
Multiemployer, Defined Benefit Pension Plans —
Over 20% of our workforce is covered by collective bargaining
agreements, which are with various union locals across the
United States. As a result of some of these agreements, certain
of our subsidiaries are participating employers in a number of
trustee-managed multiemployer, defined benefit pension plans for
the affected employees. One of the most significant
multiemployer pension plans in which we participate is the
Central States Southeast and Southwest Areas Pension Plan
(“Central States Pension Plan”), which has reported
that it adopted a rehabilitation plan as a result of its
actuarial certification for the plan year beginning
January 1, 2008. The Central States Pension Plan is in
“critical status,” as defined by the Pension
Protection Act of 2006.
In connection with our ongoing renegotiation of various
collective bargaining agreements, we may discuss and negotiate
for the complete or partial withdrawal from one or more of these
pension plans. We recognized charges to “Operating”
expenses of $26 million in 2010, $9 million in 2009
and $39 million in 2008 associated with the withdrawal of
certain bargaining units from underfunded multiemployer pension
plans. Our partial withdrawal from the Central States Pension
Plan accounted for all of our 2010 charges and $35 million
of our 2008 charges. We are still negotiating and litigating
final resolutions of our withdrawal liability for these previous
withdrawals, which could be materially higher than the charges
we have recognized. We do not believe that our withdrawals from
the multiemployer plans, individually or in the aggregate, will
have a material adverse effect on our financial condition or
liquidity. However, depending on the number of employees
withdrawn in any future period and the financial condition of
the multiemployer plans at the time of withdrawal, such
withdrawals could materially affect our results of operations in
the period of the withdrawal.
Tax Matters — We are currently in the
examination phase of IRS audits for the tax years 2010 and 2011
and expect these audits to be completed within the next 12 and
24 months, respectively. We participate in the IRS’s
Compliance Assurance Program, which means we work with the IRS
throughout the year in order to resolve any material issues
prior to the filing of our year-end tax return. We are also
currently undergoing audits by various state and local
jurisdictions that date back to 2000. In the third quarter of
2010, we finalized audits in Canada through the 2005 tax year
and are not currently under audit for any subsequent tax years.
To provide for certain potential tax exposures, we maintain a
liability for unrecognized tax benefits, the balance of which
management believes is adequate. Results of audit assessments by
taxing authorities are not currently expected to have a material
adverse impact on our results of operations or cash flows.

Restructuring [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
Restructuring |
2009 Restructuring — In January 2009, we took
steps to further streamline our organization by
(i) consolidating many of our Market Areas;
(ii) integrating the management of our recycling operations
with our other solid
waste business; and (iii) realigning our Corporate
organization with this new structure in order to provide support
functions more efficiently.
Our principal operations are managed through our Groups, which
are discussed in Note 21. Each of our four geographic
Groups had been further divided into 45 Market Areas. As a
result of our restructuring, the Market Areas were consolidated
into 25 Areas. We found that our larger Market Areas generally
were able to achieve efficiencies through economies of scale
that were not present in our smaller Market Areas, and this
reorganization has allowed us to lower costs and to continue to
standardize processes and improve productivity. In addition,
during the first quarter of 2009, responsibility for the
oversight of
day-to-day
recycling operations at our material recovery facilities and
secondary processing facilities was transferred from our Waste
Management Recycle America, or WMRA, organization to our four
geographic Groups. By integrating the management of our
recycling facilities’ operations with our other solid waste
business, we are able to more efficiently provide comprehensive
environmental solutions to our customers. In addition, as a
result of this realignment, we have significantly reduced the
overhead costs associated with managing this portion of our
business and have increased the geographic Groups’ focus on
maximizing the profitability and return on invested capital of
our business on an integrated basis.
This reorganization eliminated over 1,500 employee
positions throughout the Company. During 2009, we recognized
$50 million of pre-tax charges associated with this
restructuring, of which $41 million were related to
employee severance and benefit costs. The remaining charges were
primarily related to operating lease obligations for property
that will no longer be utilized. The following table summarizes
the charges recognized in 2009 for this restructuring by each of
our reportable segments and our Corporate and Other
organizations (in millions):
In 2010, we recognized $2 million of income related to the
reversal of pre-tax restructuring charges. Through
December 31, 2010, we had paid all of the employee
severance and benefit costs incurred as a result of this
restructuring.
2008 Restructuring — The $2 million of
restructuring expenses recognized during 2008 was related to a
reorganization of customer service functions in our Western
Group and the realignment of certain operations in our Southern
Group.

(Income) Expense from Divestitures, Asset Impairments and Unusual Items |
The following table summarizes the major components of
“(Income) expense from divestitures, asset impairments and
unusual items” for the year ended December 31 for the
respective periods (in millions):
Income from Divestitures — The net gain from
divestitures during 2008 was a result of our focus on selling
underperforming businesses and primarily related to the
divestiture of underperforming collection operations in our
Southern Group.
Asset Impairments — Through December 31,
2008, we capitalized $70 million of accumulated costs
associated with the development of a new waste and recycling
revenue management system. A significant portion of these costs
was specifically associated with the purchase of a license for
waste and recycling revenue management software and the efforts
required to develop and configure that software for our use.
After a failed pilot implementation of the software in one of
our smallest Market Areas, the development efforts associated
with the revenue management system were suspended in 2007.
During 2009, we determined to enhance and improve our existing
revenue management system and not pursue alternatives associated
with the development and implementation of the licensed
software. Accordingly, in 2009, we recognized a non-cash charge
of $51 million, $49 million of which was recognized
during the first quarter of 2009 and $2 million of which
was recognized during the fourth quarter of 2009, for the
abandonment of the licensed software.
We recognized an additional $32 million of impairment
charges during 2009, $27 million of which was recognized by
our Western Group during the fourth quarter of 2009 to fully
impair a landfill in California as a result of a change in our
expectations for the future operations of the landfill. The
remaining impairment charges were primarily attributable to a
charge required to write down certain of our investments in
portable self-storage operations to their fair value as a result
of our acquisition of a controlling financial interest in those
operations.
During 2008, we recognized a $4 million impairment charge,
primarily as a result of a decision to close a landfill in our
Southern Group.
Other — We filed a lawsuit in March 2008
related to the revenue management software implementation that
was suspended in 2007 and abandoned in 2009. In April 2010, we
settled the lawsuit and received a one-time cash payment. The
settlement resulted in an increase in income from operations for
the year ended December 31, 2010 of $77 million.

Capital Stock, Share Repurchases and Dividends |
Capital
Stock
As of December 31, 2010, we have 475.0 million shares
of common stock issued and outstanding. We have 1.5 billion
shares of authorized common stock with a par value of $0.01 per
common share. The Board of Directors is authorized to issue
preferred stock in series, and with respect to each series, to
fix its designation, relative rights (including voting,
dividend, conversion, sinking fund, and redemption rights),
preferences (including dividends and
liquidation) and limitations. We have ten million shares of
authorized preferred stock, $0.01 par value, none of which
is currently outstanding.
Share
Repurchases
The following is a summary of activity under our stock
repurchase programs for each year presented:
In July 2008, we suspended our share repurchases in connection
with a proposed acquisition. In the fourth quarter of 2008, we
determined that, given the state of the economy and the
financial markets, it would be prudent to suspend repurchases
for the foreseeable future. In June 2009, we decided that the
improvement in the capital markets and the economic environment
supported a decision to resume repurchases of our common stock
during the second half of 2009.
Our Board of Directors approved a capital allocation program for
2010 that included the authorization for expenditures of up to
$1.3 billion, comprised of approximately $615 million
in cash dividends and up to $685 million in common stock
repurchases. All of the common stock repurchases in 2010 were
made pursuant to this capital allocation program. In December
2010, the Board of Directors approved up to $575 million in
share repurchases for 2011 and we entered into plans under SEC
Rule 10b5-1
to effect market purchases of our common stock in the first
quarter of 2011. We repurchased approximately $26 million
of our common stock pursuant to these plans, through
February 14, 2011.
Future share repurchases will be made within the limits approved
by our Board of Directors at the discretion of management, and
will depend on factors similar to those considered by the Board
in making dividend declarations.
Dividends
Our quarterly dividends have been declared by our Board of
Directors and paid in accordance with our capital allocation
programs. Cash dividends declared and paid were
$604 million in 2010, or $1.26 per common share,
$569 million in 2009, or $1.16 per common share and
$531 million in 2008, or $1.08 per common share.
In December 2010, we announced that our Board of Directors
expects to increase the per share quarterly dividend from $0.315
to $0.34 for dividends declared in 2011. However, all future
dividend declarations are at the discretion of the Board of
Directors, and depend on various factors, including our net
earnings, financial condition, cash required for future business
plans and other factors the Board may deem relevant.

Stock-Based Compensation |
Employee
Stock Purchase Plan
We have an Employee Stock Purchase Plan under which employees
that have been employed for at least 30 days may purchase
shares of our common stock at a discount. The plan provides for
two offering periods for purchases: January through June and
July through December. At the end of each offering period,
employees are able to purchase shares of our common stock at a
price equal to 85% of the lesser of the market value of the
stock on the first and last day of such offering period. The
purchases are made through payroll deductions, and the number of
shares that may be purchased is limited by IRS regulations. The
total number of shares issued under the plan for the offering
periods in each of 2010, 2009 and 2008 was approximately
911,000, 969,000 and 839,000, respectively. Including the impact
of the January 2011 issuance of shares associated with the July
to December 2010 offering period, approximately 1.6 million
shares remain available for issuance under the plan.
Accounting for our Employee Stock Purchase Plan increased annual
compensation expense by approximately $7 million, or
$4 million net of tax, for 2010 and by $6 million, or
$4 million net of tax, for both 2009 and 2008.
Employee
Stock Incentive Plans
We grant equity and equity-based awards to our officers,
employees and independent directors. The Company’s 2004
Stock Incentive Plan, which authorized the issuance of up to
34 million shares of our common stock, terminated by its
terms in May 2009, at which time our stockholders approved our
2009 Stock Incentive Plan. The 2009 Plan provides for the
issuance of up to 26.2 million shares of our common stock.
As of December 31, 2010, approximately 16.0 million
shares remain available for issuance under the 2009 Plan. We
currently utilize treasury shares to meet the needs of our
equity-based compensation programs.
Pursuant to the 2009 Plan, we have the ability to issue stock
options, stock appreciation rights and stock awards, including
restricted stock, restricted stock units, or RSUs, and
performance share units, or PSUs. The terms and conditions of
equity awards granted under the 2009 Plan are determined by the
Management Development and Compensation Committee of our Board
of Directors.
The Company grants equity awards to certain key employees as
part of its long-term incentive plan, or LTIP. The annual LTIP
awards granted in 2008 and 2009 included a combination of RSUs
and PSUs. In 2010, we
re-introduced
stock options as a component of equity compensation, and key
employees were granted a combination of PSUs and stock options.
Beginning in 2008, the annual LTIP award made to the
Company’s senior leadership team, which generally includes
the Company’s executive officers, was comprised solely of
PSUs. We continued this practice in 2009; however, in 2010, the
annual LTIP award to the Company’s senior leadership team
included a combination of PSUs and stock options. During the
reported periods, the Company has also granted restricted stock
units and stock options to employees working on key initiatives;
in connection with new hires and promotions; and to field-based
managers.
Restricted Stock Units — A summary of our RSUs
is presented in the table below (units in thousands):
RSUs provide award recipients with dividend equivalents during
the vesting period, but the units may not be voted or sold until
time-based vesting restrictions have lapsed. RSUs provide for
three-year cliff vesting. Unvested units are subject to
forfeiture in the event of voluntary or for-cause termination.
RSUs are subject to pro-rata vesting upon an employee’s
retirement or involuntary termination other than for cause and
become immediately vested in the event of an employee’s
death or disability.
Compensation expense associated with RSUs is measured based on
the grant-date fair value of our common stock and is recognized
on a straight-line basis over the required employment period,
which is generally the vesting period. Compensation expense is
only recognized for those awards that we expect to vest, which
we estimate based upon an assessment of current period and
historical forfeitures.
Performance Share Units — PSUs are payable in
shares of common stock after the end of a three-year performance
period and after the Company’s financial results for the
entire performance period are reported, typically in mid to late
February of the succeeding year. At the end of the performance
period, the number of shares awarded can range from 0% to 200%
of the targeted amount, depending on the Company’s
performance against pre-established financial targets. A summary
of our PSUs is presented in the table below (units in thousands):
PSUs have no voting rights. Beginning with the PSU awards made
in 2007, PSUs receive dividend equivalents that are paid out in
cash based on actual performance at the end of the awards’
performance period. In the case of the PSUs with the performance
period ended December 31, 2010 that expired without
vesting, no dividend equivalents will be paid. PSUs are payable
to an employee (or his beneficiary) upon death or disability as
if that employee had remained employed until the end of the
performance period, are subject to pro-rata vesting upon an
employee’s retirement or involuntary termination other than
for cause and are subject to forfeiture in the event of
voluntary or for-cause termination.
Compensation expense associated with PSUs that continue to vest
based on future performance is measured based on the grant-date
fair value of our common stock. Compensation expense is
recognized ratably over the performance period based on our
estimated achievement of the established performance criteria.
Compensation expense is only recognized for those awards that we
expect to vest, which we estimate based upon an assessment of
both the probability that the performance criteria will be
achieved and current period and historical forfeitures.
Stock Options — Prior to 2005, stock options
were the primary form of equity-based compensation we granted to
our employees. In 2010, the Management Development and
Compensation Committee decided to re-introduce stock options as
a component of our LTIP awards. All of our previously granted
stock option awards have vested, with the exception of any
grants pursuant to the reload feature discussed in footnote
(a) to the table below. The stock options will vest in 25%
increments on the first two anniversaries of the date of grant
and the remaining 50% will vest on the third anniversary. The
exercise price of the options is the fair market value of our
common stock on the date of grant, and the options have a term
of 10 years. A summary of our stock options is presented in
the table below (shares in thousands):
We received cash proceeds of $54 million, $20 million
and $37 million during the years ended December 31,
2010, 2009 and 2008, respectively, from our employees’
stock option exercises. We also realized tax benefits from these
stock option exercises during the years ended December 31,
2010, 2009 and 2008 of $10 million, $5 million and
$6 million, respectively. These amounts have been presented
as cash inflows in the “Cash flows from financing
activities” section of our Consolidated Statements of Cash
Flows.
Exercisable stock options at December 31, 2010, were as
follows (shares in thousands):
All unvested stock options granted in 2010 shall become
exercisable upon the award recipient’s death or disability.
In the event of a recipient’s retirement, stock options
shall continue to vest pursuant to the original schedule set
forth in the award agreement. If the recipient is terminated by
the Company without cause, the recipient
shall be entitled to exercise all 2010 stock options outstanding
and exercisable prior to such termination. All outstanding stock
options, whether exercisable or not, are forfeited upon
termination with cause.
We account for our employee stock options under the fair value
method of accounting using a Black-Scholes methodology to
measure stock option expense at the date of grant. The fair
value of the stock options at the date of grant is amortized to
expense over the vesting period. The following table presents
the assumptions used to value employee stock options granted
during the year ended December 31, 2010 under the
Black-Scholes valuation model:
The Company bases its expected option life on the expected
exercise and termination behavior of its optionees and an
appropriate model of the Company’s future stock price. The
expected volatility assumption is derived from the historical
volatility of the Company’s common stock over the most
recent period commensurate with the estimated expected life of
the Company’s stock options, combined with other relevant
factors including implied volatility in market-traded options on
the Company’s stock. The dividend yield is the annual rate
of dividends per share over the exercise price of the option as
of the grant date.
For the years ended December 31, 2010, 2009 and 2008, we
recognized $28 million, $22 million, and
$42 million, respectively, of compensation expense
associated with RSU, PSU and stock option awards as a component
of “Selling, general and administrative” expenses in
our Consolidated Statement of Operations. Our “Provision
for income taxes” for the years ended December 31,
2010, 2009 and 2008 includes related deferred income tax
benefits of $11 million, $9 million and
$16 million, respectively. We have not capitalized any
equity-based compensation costs during the years ended
December 31, 2010, 2009 and 2008.
Compensation expense recognized in 2009 was significantly less
than expense recognized in 2008 primarily due to the
Company’s determination that it was no longer probable that
the targets established for PSUs granted in 2008 would be met.
Accordingly, during the second quarter of 2009, we recognized an
adjustment to “Selling, general and administrative”
expenses for the reversal of all previously recognized
compensation expense associated with this award. Additionally,
we did not recognize any compensation expense in 2010 associated
with the PSUs granted in 2008. These PSUs expired without
vesting on December 31, 2010. As of December 31, 2010,
we estimate that a total of approximately $40 million of
currently unrecognized compensation expense will be recognized
in future periods for unvested RSU, PSU and stock option awards
issued and outstanding. Unrecognized compensation expense
associated with all unvested awards currently outstanding is
expected to be recognized over a weighted average period of
approximately two years.
Non-Employee
Director Plans
Our non-employee directors currently receive annual grants of
shares of our common stock, payable in two equal installments,
under the 2009 Plan described above. Prior to 2008, our
directors received deferred stock units and were allowed to
elect to defer a portion of their cash compensation in the form
of deferred stock units, to be paid out in shares of our common
stock at the termination of board service, pursuant to our
2003 Directors’ Deferred Compensation Plan. In late
2007, each member of the Board of Directors elected to receive
payment of shares for his deferred stock units at the end of
December 2008 and recognized taxable income on such payment. The
Board of Directors terminated the 2003 Directors’ Plan
in 2009 and, as a result, no shares remain available for
issuance under that plan.

Fair Value Measurements |
Assets
and Liabilities Accounted for at Fair Value
Authoritative guidance associated with fair value measurements
provides a framework for measuring fair value and establishes a
fair value hierarchy that prioritizes the inputs used to measure
fair value, giving the highest priority to unadjusted quoted
prices in active markets for identical assets or liabilities
(Level 1 inputs) and the lowest priority to unobservable
inputs (Level 3 inputs).
We use valuation techniques that maximize the use of observable
inputs and minimize the use of unobservable inputs. In measuring
the fair value of our assets and liabilities, we use market data
or assumptions that we believe market participants would use in
pricing an asset or liability, including assumptions about risk
when appropriate. Our assets and liabilities that are measured
at fair value on a recurring basis include the following (in
millions):
Cash
Equivalents
Cash equivalents are reflected at fair value in our Consolidated
Financial Statements based upon quoted market prices and consist
primarily of money market funds that invest in
U.S. government obligations with original maturities of
three months or less.
Available-for-Sale
Securities
Available for-sale securities are recorded at fair value based
on quoted market prices. These assets include restricted trusts
and escrow accounts invested in money market mutual funds,
equity-based mutual funds and other equity securities. As
discussed in Note 20, effective January 1, 2010, we
deconsolidated the trusts for which power over significant
activities of the trust is shared, which reduced our restricted
trust and escrow accounts by $109 million as of
January 1, 2010. Beginning in 2010, our interests in these
variable interest entities have been accounted for as
investments in unconsolidated entities and receivables.
The cost basis of our direct investment in equity securities,
included as a component of
“Available-for-sale
securities” above, was $2 million as of
December 31, 2010 and 2009. The cost basis of investments
in equity-based mutual funds was $75 million as of
December 31, 2010 and 2009 and is included above as a
component of “Interest in
available-for-sale
securities of unconsolidated entities” as of
December 31, 2010, and as a component of
“Available-for-sale
securities” as of December 31, 2009. Unrealized
holding gains and losses on these instruments are recorded as
either an increase or decrease to the asset balance and deferred
as a component of “Accumulated other comprehensive
income” in the equity section of our Consolidated Balance
Sheets. The net unrealized holding gains on equity-based mutual
funds, net of taxes, were $5 million and $2 million as
of December 31, 2010 and 2009, respectively. The net
unrealized holding losses on equity securities, net of taxes,
were immaterial as of December 31, 2010 and 2009. The fair
value of our remaining
available-for-sale
securities approximates our cost basis in the investments.
Interest
Rate Derivatives
As of December 31, 2010, we are party to
(i) fixed-to-floating
interest rate swaps that are designated as fair value hedges of
our currently outstanding senior notes; and
(ii) forward-starting interest rate swaps that are
designated as cash flow hedges of anticipated interest payments
for future fixed-rate debt issuances. Our
fixed-to-floating
interest rate swaps and forward-starting interest rate swaps are
LIBOR-based instruments. Accordingly, these derivatives are
valued using a third-party pricing model that incorporates
information about LIBOR yield curves for each instrument’s
respective term. The third-party pricing model used to value our
interest rate derivatives also incorporates Company and
counterparty credit valuation adjustments, as appropriate.
Counterparties to our interest rate derivatives are financial
institutions who participate in our $2.0 billion revolving
credit facility. Valuations of our interest rate derivatives may
fluctuate significantly from
period-to-period
due to volatility in underlying interest rates, which are driven
by market conditions and the scheduled maturities of the
derivatives. Refer to Note 8 for additional information
regarding our interest rate derivatives.
Foreign
Currency Derivatives
Our foreign currency derivatives are valued using a third-party
pricing model that incorporates information about forward
Canadian dollar exchange prices as of the reporting date. The
third-party pricing model used to value our foreign currency
derivatives also incorporates Company and counterparty credit
valuation adjustments, as appropriate. Counterparties to these
contracts are financial institutions who participate in our
$2.0 billion revolving credit facility. Valuations may
fluctuate significantly from
period-to-period
due to volatility in the Canadian dollar to U.S. dollar
exchange rate. Refer to Note 8 for additional information
regarding our foreign currency derivatives.
Fair
Value of Debt
At both December 31, 2010 and 2009, the carrying value of
our debt was approximately $8.9 billion. The carrying value
of our debt includes adjustments for both the unamortized fair
value adjustments related to terminated hedge arrangements and
fair value adjustments of debt instruments that are currently
hedged.
The estimated fair value of our debt was approximately
$9.2 billion at December 31, 2010 and approximately
$9.3 billion at December 31, 2009. The estimated fair
value of our senior notes is based on quoted market prices. The
carrying value of remarketable debt approximates fair value due
to the short-term nature of the interest rates. The fair value
of our other debt is estimated using discounted cash flow
analysis, based on rates we would currently pay for similar
types of instruments.
Although we have determined the estimated fair value amounts
using available market information and commonly accepted
valuation methodologies, considerable judgment is required in
interpreting market data to develop the estimates of fair value.
Accordingly, our estimates are not necessarily indicative of the
amounts that we, or holders of the instruments, could realize in
a current market exchange. The use of different assumptions
and/or
estimation methodologies could have a material effect on the
estimated fair values. The fair value estimates are based on
information available as of December 31, 2010 and
December 31, 2009. These amounts have not been revalued
since those dates, and current estimates of fair value could
differ significantly from the amounts presented.

Acquisitions and Divestitures |
Acquisitions
We continue to pursue the acquisition of businesses that are
accretive to our solid waste operations and enhance and expand
our existing service offerings. We have seen the greatest
opportunities for realizing superior returns from tuck-in
acquisitions, which are primarily the purchases of collection
operations that enhance our existing route structures and are
strategically located near our existing disposal operations.
In 2010, we acquired businesses primarily related to our
collection and
waste-to-energy
operations. Total consideration, net of cash acquired, for
acquisitions was $427 million, which included
$379 million in cash payments, $20 million in
contributed assets, a liability for additional cash payments
with an estimated fair value of $23 million, and assumed
liabilities of $5 million. The additional cash payments are
contingent upon achievement by the acquired businesses of
certain negotiated goals, which generally included targeted
revenues. At the date of acquisition, our estimated maximum
obligations for the contingent cash payments were
$23 million. As of December 31, 2010, we had paid
$8 million of this contingent consideration. In 2010, we
also paid $20 million of contingent consideration
associated with acquisitions completed in 2009.
The allocation of purchase price was primarily to “Property
and equipment,” which had an estimated fair value of
$279 million; “Other intangible assets,” which
had an estimated fair value of $98 million; and
“Goodwill” of $77 million. Goodwill is primarily
a result of expected synergies from combining the acquired
businesses with our existing operations and is tax deductible.
In 2009, we acquired businesses primarily related to our
collection operations. Total consideration, net of cash
acquired, for acquisitions was $329 million, which included
$259 million in cash payments, a liability for additional
cash payments with an estimated fair value of $46 million,
and assumed liabilities of $24 million. The additional cash
payments are contingent upon achievement by the acquired
businesses of certain negotiated goals, which generally included
targeted revenues. At the date of acquisition, our estimated
obligations for the contingent cash payments were between
$42 million and $56 million. As of December 31,
2009, we had paid $15 million of this contingent
consideration. In 2009, we also paid $7 million of
contingent consideration associated with acquisitions completed
in 2008.
The allocation of purchase price was primarily to “Property
and equipment,” which had an estimated fair value of
$102 million; “Other intangible assets,” which
had an estimated fair value of $105 million; and
“Goodwill” of $125 million. Goodwill is primarily
a result of expected synergies from combining the acquired
businesses with our existing operations and is tax deductible.
Our 2009 acquisitions included the purchase of the remaining
equity interest in one of our portable self-storage investments,
increasing our equity interest in this entity from 50% to 100%.
As a result of this acquisition, we recognized a $4 million
loss for the remeasurement of the fair value of our initial
equity investment, which was determined to be $5 million.
This loss was recognized as a component of “(Income)
expense from divestitures, asset impairments and unusual
items” in our Statement of Operations.
In 2008, we completed several acquisitions for a cost, net of
cash acquired, of $280 million.
Divestitures
The aggregate sales price for divestitures of operations was
$1 million in 2010, $1 million in 2009 and
$59 million in 2008. The proceeds from these sales were
comprised substantially of cash. We recognized net gains on
these divestitures of $1 million in 2010 and
$33 million in 2008. The impact to our 2009 income from
operations of gains and losses on divestitures was less than
$1 million. These divestitures were made as part of our
initiative to improve or divest certain underperforming and
non-strategic operations.

Variable Interest Entities |
Following is a description of our financial interests in
variable interest entities that we consider significant,
including (i) those for which we have determined that we
are the primary beneficiary of the entity and, therefore, have
consolidated the entities into our financial statements; and
(ii) those that represent a significant interest in an
unconsolidated entity.
Consolidated
Variable Interest Entities
Waste-to-Energy
LLCs — In June 2000, two limited liability
companies were established to purchase interests in existing
leveraged lease financings at three
waste-to-energy
facilities that we lease, operate and maintain. We own a 0.5%
interest in one of the LLCs (“LLC I”) and a 0.25%
interest in the second LLC (“LLC II”). John Hancock
Life Insurance Company owns 99.5% of LLC I and 99.75% of LLC II
is owned by LLC I and the CIT Group. In 2000, Hancock and CIT
made an initial investment of $167 million in the LLCs,
which was used to purchase the three
waste-to-energy
facilities and assume the seller’s indebtedness. Under the
LLC agreements, the LLCs shall be dissolved upon the occurrence
of any of the following events: (i) a written decision of
all members of the LLCs; (ii) December 31, 2063;
(iii) a court’s dissolution of the LLCs; or
(iv) the LLCs ceasing to own any interest in the
waste-to-energy
facilities.
Income, losses and cash flows of the LLCs are allocated to the
members based on their initial capital account balances until
Hancock and CIT achieve targeted returns; thereafter, we will
receive 80% of the earnings of each of the LLCs and Hancock and
CIT will be allocated the remaining 20% proportionate to their
respective equity interests. All capital allocations made
through December 31, 2010 have been based on initial
capital account balances as the target returns have not yet been
achieved.
Our obligations associated with our interests in the LLCs are
primarily related to the lease of the facilities. In addition to
our minimum lease payment obligations, we are required to make
cash payments to the LLCs for differences between fair market
rents and our minimum lease payments. These payments are subject
to adjustment based on factors that include the fair market
value of rents for the facilities and lease payments made
through the
re-measurement
dates. In addition, we may also be required under certain
circumstances to make capital contributions to the LLCs based on
differences between the fair market value of the facilities and
defined termination values as provided for in the underlying
lease agreements, although we believe the likelihood of the
occurrence of these circumstances is remote.
We have determined that we are the primary beneficiary of the
LLCs and consolidate these entities in our Consolidated
Financial Statements because (i) all of the equity owners
of the LLCs are considered related parties for purposes of
applying this accounting guidance; (ii) the equity owners
share power over the significant activities of the LLCs; and
(iii) we are the entity within the related party group
whose activities are most closely associated with the LLCs.
As of December 31, 2010, our Consolidated Balance Sheet
includes $319 million of net property and equipment
associated with the LLCs’
waste-to-energy
facilities and $240 million in noncontrolling interests
associated with Hancock’s and CIT’s interests in the
LLCs. As of December 31, 2010, all debt obligations of the
LLCs have been paid in full and, therefore, the LLCs have no
liabilities. During the years ended December 31, 2010,
2009, and 2008, we recognized expense of $50 million,
$50 million and $41 million, respectively, for
Hancock’s and CIT’s noncontrolling interests in the
LLCs’ earnings. The LLCs’ earnings relate to the
rental income generated from leasing the facilities to our
subsidiaries, reduced by depreciation expense. The LLCs’
rental income is eliminated in WM’s consolidation.
Significant
Unconsolidated Variable Interest Entities
Trusts for Capping, Closure, Post-Closure or Environmental
Remediation Obligations — We have significant
financial interests in trust funds that were created to settle
certain of our capping, closure, post-closure or environmental
remediation obligations. We have determined that we are not the
primary beneficiary of certain of these trust funds because
power over the trusts’ significant activities is shared.
The deconsolidation of these variable interest entities as of
January 1, 2010, in accordance with the new FASB guidance
discussed in Note 2, decreased our restricted trust and
escrow accounts by $109 million; increased investments in
unconsolidated entities by $27 million; increased
receivables, principally long-term, by $51 million; and
decreased noncontrolling interests by $31 million.
Beginning in 2010, our interests in these variable interest
entities have been accounted for as investments in
unconsolidated entities and receivables. These amounts are
recorded in “Other receivables” and as long-term
“Other assets” in our Consolidated Balance Sheet. Our
investments and receivables related to the trusts had a fair
value of $105 million as of January 1, 2010 and
$103 million as of December 31, 2010. We continue to
reflect our interests in the unrealized gains and losses on
marketable securities held by these trusts as a component of
accumulated other comprehensive income. The deconsolidation of
these variable interest entities has not materially affected our
financial position, results of operations or cash flows for the
periods presented.
As the party with primary responsibility to fund the related
capping, closure, post-closure or environmental remediation
activities, we are exposed to risk of loss as a result of
potential changes in the fair value of the assets of the trust.
The fair value of trust assets can fluctuate due to
(i) changes in the market value of the investments held by
the trusts; and (ii) credit risk associated with trust
receivables. Although we are exposed to changes in the fair
value of the trust assets, we currently expect the trust funds
to continue to meet the statutory requirements for which they
were established.
Investment in Federal Low-income Housing Tax
Credits — In April 2010, we acquired a
noncontrolling interest in a limited liability company
established to invest in and manage low-income housing
properties. Along with the other equity investor, we support the
operations of the entity in exchange for a pro-rata share of the
tax credits it generates. Our target return on the investment is
guaranteed and, therefore, we do not believe that we have
any material exposure to loss. Our consideration for this
investment totaled $221 million, which was comprised of a
$215 million note payable and an initial cash payment of
$6 million. At December 31, 2010, our investment
balance was $202 million. We determined that we are not the
primary beneficiary of this entity as we do not have the power
to direct the entity’s activities. Accordingly, we account
for this investment under the equity method of accounting and do
not consolidate the entity. Additional information related to
this investment is discussed in Note 9.

Quarterly Financial Data (Unaudited) |
The following table summarizes the unaudited quarterly results
of operations for 2010 and 2009 (in millions, except per share
amounts):
Basic and diluted earnings per common share for each of the
quarters presented above is based on the respective weighted
average number of common and dilutive potential common shares
outstanding for each quarter and the sum of the quarters may not
necessarily be equal to the full year basic and diluted earnings
per common share amounts.
Our operating revenues normally tend to be somewhat higher in
the summer months, primarily due to the traditional seasonal
increase in the volume of construction and demolition waste. The
volumes of industrial and residential waste in certain regions
where we operate also tend to increase during the summer months.
Our second and third quarter revenues and results of operations
typically reflect these seasonal trends, although we saw a
significantly weaker seasonal volume increase during 2009 than
we generally experience. Additionally, from time to time, our
operating results are significantly affected by certain
transactions or events that management believes are not
indicative or representative of our results. The following

New Accounting Pronouncement (Unaudited) |
Multiple-Deliverable Revenue Arrangements — In
October 2009, the FASB amended authoritative guidance associated
with multiple-deliverable revenue arrangements. This amended
guidance addresses the determination of when individual
deliverables within an arrangement may be treated as separate
units of accounting and modifies the manner in which
consideration is allocated across the separately identifiable
deliverables. The amendments to authoritative guidance
associated with multiple-deliverable revenue arrangements became
effective for the Company on January 1, 2011. The new
accounting standard may be applied either retrospectively for
all periods presented or prospectively to arrangements entered
into or materially modified after the date of adoption. We do
not expect that the adoption of this guidance will have a
material impact on our consolidated financial statements.
However, our adoption of this guidance may significantly impact
our accounting and reporting for future revenue arrangements to
the extent they are material.

Summary of Significant Accounting Policies (Policies) [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Consolidation of Variable Interest Entities |
Consolidation of Variable Interest Entities —
In June 2009, the Financial Accounting Standards Board, or FASB,
issued revised authoritative guidance associated with the
consolidation of variable interest entities. The new guidance
primarily uses a qualitative approach for determining whether an
enterprise is the primary beneficiary of a variable interest
entity, and is, therefore, required to consolidate the entity.
This new guidance generally defines the primary beneficiary as
the entity that has (i) the power to direct the activities
of the variable interest entity that can most significantly
impact the entity’s performance and (ii) the
obligation to absorb losses and the right to receive benefits
from the variable interest entity that could be significant from
the perspective of the entity. The new guidance also requires
that we continually reassess whether we are the primary
beneficiary of a variable interest entity rather than conducting
a reassessment only upon the occurrence of specific events.
As a result of our implementation of this guidance, effective
January 1, 2010, we deconsolidated certain capping,
closure, post-closure and environmental remediation trusts
because we share power over significant activities of these
trusts with others. Our financial interests in these entities
are discussed in Note 20. The deconsolidation of these
trusts has not materially affected our financial position,
results of operations or cash flows during the periods presented.
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Fair Value Measurements |
Fair Value Measurements — In September 2006,
the FASB issued authoritative guidance associated with fair
value measurements. This guidance defined fair value,
established a framework for measuring fair value, and expanded
disclosures about fair value measurements. In February 2008, the
FASB delayed the effective date of the guidance for all
non-financial assets and non-financial liabilities, except those
that are measured at fair value on a recurring basis.
Accordingly, we adopted this guidance for assets and liabilities
recognized at fair value on a recurring basis effective
January 1, 2008 and adopted the guidance for non-financial
assets and liabilities measured on a non-recurring basis
effective January 1, 2009. The application of the fair
value framework did not have a material impact on our
consolidated financial position, results of operations or cash
flows.
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Business Combinations |
Business Combinations — In December 2007, the
FASB issued revisions to the authoritative guidance associated
with business combinations. This guidance clarified and revised
the principles for how an acquirer recognizes and measures
identifiable assets acquired, liabilities assumed, and any
noncontrolling interest in the acquiree. This guidance also
addressed the recognition and measurement of goodwill acquired
in business combinations and expanded disclosure requirements
related to business combinations. Effective January 1,
2009, we adopted the FASB’s revised guidance associated
with business combinations. The portions of this guidance that
relate to business combinations completed before January 1,
2009 did not have a material impact on our consolidated
financial statements. Further, business combinations completed
subsequent to January 1, 2009, which are discussed in
Note 19, have not been material to our financial position,
results of operations or cash flows. However, to the extent that
future business combinations are material, our adoption of the
FASB’s revised authoritative guidance associated with
business combinations may significantly impact our accounting
and reporting for future acquisitions, principally as a result
of (i) expanded requirements to value acquired assets,
liabilities and contingencies at their fair values when such
amounts can be determined and (ii) the requirement that
acquisition-related transaction and restructuring costs be
expensed as incurred rather than capitalized as a part of the
cost of the acquisition.
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Noncontrolling Interests in Consolidated Financial Statements |
Noncontrolling Interests in Consolidated Financial
Statements — In December 2007, the FASB issued
authoritative guidance that established accounting and reporting
standards for noncontrolling interests in subsidiaries and for
the de-consolidation of a subsidiary. The guidance also
established that a noncontrolling interest in a subsidiary is an
ownership interest in the consolidated entity that should be
reported as equity in the consolidated financial statements. We
adopted this guidance on January 1, 2009. The presentation
and disclosure requirements of this guidance, which must be
applied retrospectively for all periods presented, resulted in
reclassifications to our prior period consolidated financial
information and the remeasurement of our 2008 effective tax
rate, which is discussed in Note 9.
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Employers' Accounting for Defined Benefit Pension and Other Post-retirement Plans |
Employers’ Accounting for Defined Benefit Pension and
Other Post-retirement Plans — In September 2006,
the FASB issued revisions to the authoritative guidance
associated with the accounting and reporting of post-retirement
benefit plans. This guidance required companies to recognize the
overfunded or underfunded status of their defined benefit
pension and other post-retirement plans as an asset or liability
and to recognize changes in that funded status through
comprehensive income in the year in which the changes occur. We
adopted these recognition provisions effective December 31,
2006. The FASB’s revised guidance also required companies
to measure the funded status of defined benefit pension and
other post-retirement plans as of their year-end reporting date.
These measurement date provisions were effective for us as of
December 31, 2008. We applied the measurement provisions by
measuring our benefit obligations as of September 30, 2007,
our prior measurement date, and recognizing a pro-rata share of
net benefit costs for the transition period from October 1,
2007 to December 31, 2008 as a cumulative effect of change
in accounting principle in retained earnings as of
December 31, 2008. The application of the recognition and
measurement provisions of this revised authoritative guidance
did not have a material impact on our financial position or
results of operations for the periods presented.

subsequent events through the date and time the financial

Estimates and Assumptions |
Estimates
and Assumptions
In preparing our financial statements, we make numerous
estimates and assumptions that affect the accounting for and
recognition and disclosure of assets, liabilities, equity,
revenues and expenses. We must make these estimates and
assumptions because certain information that we use is dependent
on future events, cannot be calculated with a high degree of
precision from data available or simply cannot be readily
calculated based on generally accepted methods. In some cases,
these estimates are particularly difficult to determine and we
must exercise significant judgment. In preparing our financial
statements, the most difficult, subjective and complex estimates
and the assumptions that present the greatest amount of
uncertainty relate to our accounting for landfills,
environmental remediation liabilities, asset impairments,
deferred income taxes, and reserves associated with our insured
and self-insured claims. Each of these items is discussed in
additional detail below. Actual results could differ materially
from the estimates and assumptions that we use in the
preparation of our financial statements.

Cash and Cash Equivalents |
Cash

Cash and cash equivalents consist primarily of cash on deposit
and money market funds that invest in U.S. government
obligations with original maturities of three months or less.
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Concentrations of Credit Risk |
Concentrations
of Credit Risk
Financial instruments that potentially subject us to
concentrations of credit risk consist primarily of cash and cash
equivalents, investments held within our trust funds and escrow
accounts, accounts receivable and derivative instruments. We
make efforts to control our exposure to credit risk associated
with these instruments by (i) placing our assets and other
financial interests with a diverse group of credit-worthy
financial institutions; (ii) holding high-quality financial
instruments while limiting investments in any one instrument;
and (iii) maintaining strict policies over credit extension
that include credit evaluations, credit limits and monitoring
procedures, although generally we do not have collateral
requirements for credit extensions. We also control our exposure
associated with trade receivables by discontinuing service, to
the extent allowable, to non-paying customers. However, our
overall credit risk associated with trade receivables is limited
due to the large number of geographically diverse customers we
service. At December 31, 2010 and 2009, no single customer
represented greater than 5% of total accounts receivable.
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Trade and Other Receivables |
Trade
and Other Receivables
Our receivables are recorded when billed or when cash is
advanced and represent claims against third parties that will be
settled in cash. The carrying value of our receivables, net of
the allowance for doubtful accounts, represents the estimated
net realizable value. We estimate our allowance for doubtful
accounts based on historical collection trends; type of
customer, such as municipal or commercial; the age of
outstanding receivables; and existing economic conditions. If
events or changes in circumstances indicate that specific
receivable balances may be impaired, further consideration is
given to the collectibility of those balances and the allowance
is adjusted accordingly. Past-due receivable balances are
written off when our internal collection efforts have been
unsuccessful. Also, we recognize interest income on long-term
interest-bearing notes receivable as the interest accrues under
the terms of the notes.

Landfill Accounting |
Landfill
Accounting
Cost Basis of Landfill Assets — We capitalize
various costs that we incur to make a landfill ready to accept
waste. These costs generally include expenditures for land
(including the landfill footprint and required landfill buffer
property); permitting; excavation; liner material and
installation; landfill leachate collection systems; landfill gas
collection systems; environmental monitoring equipment for
groundwater and landfill gas; and directly related engineering,
capitalized interest,
on-site road
construction and other capital infrastructure costs. The cost
basis of our landfill assets also includes asset retirement
costs, which represent estimates of future costs associated with
landfill capping, closure and post-closure activities. These
costs are discussed below.
Capping, Closure and Post-Closure Costs —
Following is a description of our asset retirement activities
and our related accounting:
We develop our estimates of these obligations using input from
our operations personnel, engineers and accountants. Our
estimates are based on our interpretation of current
requirements and proposed regulatory changes and are intended to
approximate fair value. Absent quoted market prices, the
estimate of fair value is based on the best available
information, including the results of present value techniques.
In many cases, we contract with third parties to fulfill our
obligations for capping, closure and post-closure. We use
historical experience, professional engineering judgment and
quoted and actual prices paid for similar work to determine the
fair value of these obligations. We are required to recognize
these obligations at market prices whether we plan to contract
with third parties or perform the work ourselves. In those
instances where we perform the work with internal resources, the
incremental profit margin realized is recognized as a component
of operating income when the work is performed.
Once we have determined the capping, closure and post-closure
costs, we inflate those costs to the expected time of payment
and discount those expected future costs back to present value.
During the years ended December 31, 2010, 2009 and 2008, we
inflated these costs in current dollars until the expected time
of payment using an inflation rate of 2.5%. We discount these
costs to present value using the credit-adjusted, risk-free rate
effective at the time an obligation is incurred, consistent with
the expected cash flow approach. Any changes in expectations
that result in an upward revision to the estimated cash flows
are treated as a new liability and discounted at the current
rate while downward revisions are discounted at the historical
weighted-average rate of the recorded obligation. As a result,
the credit-adjusted, risk-free discount rate used to calculate
the present value of an obligation is specific to each
individual asset retirement obligation. The weighted-average
rate applicable to our asset retirement obligations at
December 31, 2010 is between 6.0% and 8.0%, the range of
the credit-adjusted, risk-free discount rates effective since we
adopted the FASB’s authoritative guidance related to asset
retirement obligations in 2003. We expect to apply a
credit-adjusted, risk-free discount rate of 5.5% to liabilities
incurred in the first quarter of 2011.
We record the estimated fair value of capping, closure and
post-closure liabilities for our landfills based on the capacity
consumed through the current period. The fair value of capping
obligations is developed based on our estimates of the airspace
consumed to date for each capping event and the expected timing
of each capping event. The fair value of closure and
post-closure obligations is developed based on our estimates of
the airspace consumed to date for the entire landfill and the
expected timing of each closure and post-closure activity.
Because these
obligations are measured at estimated fair value using present
value techniques, changes in the estimated cost or timing of
future capping, closure and post-closure activities could result
in a material change in these liabilities, related assets and
results of operations. We assess the appropriateness of the
estimates used to develop our recorded balances annually, or
more often if significant facts change.
Changes in inflation rates or the estimated costs, timing or
extent of future capping and closure and post-closure activities
typically result in both (i) a current adjustment to the
recorded liability and landfill asset; and (ii) a change in
liability and asset amounts to be recorded prospectively over
either the remaining capacity of the related discrete capping
event or the remaining permitted and expansion airspace (as
defined below) of the landfill. Any changes related to the
capitalized and future cost of the landfill assets are then
recognized in accordance with our amortization policy, which
would generally result in amortization expense being recognized
prospectively over the remaining capacity of the capping event
or the remaining permitted and expansion airspace of the
landfill, as appropriate. Changes in such estimates associated
with airspace that has been fully utilized result in an
adjustment to the recorded liability and landfill assets with an
immediate corresponding adjustment to landfill airspace
amortization expense.
During the years ended December 31, 2010, 2009 and 2008,
adjustments associated with changes in our expectations for the
timing and cost of future capping, closure and post-closure of
fully utilized airspace resulted in $13 million,
$14 million and $3 million in net credits to landfill
airspace amortization expense, respectively, with the majority
of these credits resulting from revised estimates associated
with capping changes. In managing our landfills, our engineers
look for ways to reduce or defer our construction costs,
including capping costs. The benefit recognized in these years
was generally the result of (i) concerted efforts to
improve the operating efficiencies of our landfills and volume
declines, both of which have allowed us to delay spending for
capping activities; (ii) effectively managing the cost of
capping material and construction; or (iii) landfill
expansions that resulted in reduced or deferred capping costs.
Interest accretion on capping, closure and post-closure
liabilities is recorded using the effective interest method and
is recorded as capping, closure and post-closure expense, which
is included in “Operating” costs and expenses within
our Consolidated Statements of Operations.
Amortization of Landfill Assets — The
amortizable basis of a landfill includes (i) amounts
previously expended and capitalized; (ii) capitalized
landfill capping, closure and post-closure costs;
(iii) projections of future purchase and development costs
required to develop the landfill site to its remaining permitted
and expansion capacity; and (iv) projected asset retirement
costs related to landfill capping, closure and post-closure
activities.
Amortization is recorded on a
units-of-consumption
basis, applying expense as a rate per ton. The rate per ton is
calculated by dividing each component of the amortizable basis
of a landfill by the number of tons needed to fill the
corresponding asset’s airspace. For landfills that we do
not own, but operate through operating or lease arrangements,
the rate per ton is calculated based on expected capacity to be
utilized over the lesser of the contractual term of the
underlying agreement or the life of the landfill.
We apply the following guidelines in determining a
landfill’s remaining permitted and expansion airspace:
For unpermitted airspace to be initially included in our
estimate of remaining permitted and expansion airspace, the
expansion effort must meet all of the criteria listed above.
These criteria are evaluated by our field-based engineers,
accountants, managers and others to identify potential obstacles
to obtaining the permits. Once the unpermitted airspace is
included, our policy provides that airspace may continue to be
included in remaining permitted and expansion airspace even if
these criteria are no longer met, based on the facts and
circumstances of a specific landfill. In these circumstances,
continued inclusion must be approved through a landfill-specific
review process that includes approval by our Chief Financial
Officer and a review by the Audit Committee of our Board of
Directors on a quarterly basis. Of the 33 landfill sites
with expansions at December 31, 2010, 14 landfills
required the Chief Financial Officer to approve the inclusion of
the unpermitted airspace. Eight of these landfills required
approval by our Chief Financial Officer because of community or
political opposition that could impede the expansion process.
The remaining six landfills required approval primarily due to
the permit application processes not meeting the one- or
five-year requirements.
When we include the expansion airspace in our calculations of
remaining permitted and expansion airspace, we also include the
projected costs for development, as well as the projected asset
retirement costs related to capping, closure and post-closure of
the expansion in the amortization basis of the landfill.
Once the remaining permitted and expansion airspace is
determined in cubic yards, an airspace utilization factor, or
AUF, is established to calculate the remaining permitted and
expansion capacity in tons. The AUF is established using the
measured density obtained from previous annual surveys and is
then adjusted to account for settlement. The amount of
settlement that is forecasted will take into account several
site-specific factors including current and projected mix of
waste type, initial and projected waste density, estimated
number of years of life remaining, depth of underlying waste,
anticipated access to moisture through precipitation or
recirculation of landfill leachate, and operating practices. In
addition, the initial selection of the AUF is subject to a
subsequent multi-level review by our engineering group, and the
AUF used is reviewed on a periodic basis and revised as
necessary. Our historical experience generally indicates that
the impact of settlement at a landfill is greater later in the
life of the landfill when the waste placed at the landfill
approaches its highest point under the permit requirements.
After determining the costs and remaining permitted and
expansion capacity at each of our landfills, we determine the
per ton rates that will be expensed as waste is received and
deposited at the landfill by dividing the costs by the
corresponding number of tons. We calculate per ton amortization
rates for each landfill for assets associated with each capping
event, for assets related to closure and post-closure activities
and for all other costs capitalized or to be capitalized in the
future. These rates per ton are updated annually, or more often,
as significant facts change.
It is possible that actual results, including the amount of
costs incurred, the timing of capping, closure and post-closure
activities, our airspace utilization or the success of our
expansion efforts could ultimately turn out to be significantly
different from our estimates and assumptions. To the extent that
such estimates, or related assumptions, prove to be
significantly different than actual results, lower profitability
may be experienced due to higher amortization rates or higher
expenses, or higher profitability may result if the opposite
occurs. Most significantly, if it is determined that expansion
capacity should no longer be considered in calculating the
recoverability of a landfill asset, we may be required to
recognize an asset impairment or incur significantly higher
amortization expense. If it is determined that the likelihood of
receiving an expansion permit has become remote, the capitalized
costs related to the expansion effort are expensed immediately.

Environmental Remediation Liabilities |
Environmental
Remediation Liabilities
We are subject to an array of laws and regulations relating to
the protection of the environment. Under current laws and
regulations, we may have liabilities for environmental damage
caused by operations, or for damage caused by conditions that
existed before we acquired a site. These liabilities include
potentially responsible party (“PRP”) investigations,
settlements, and certain legal and consultant fees, as well as
costs directly associated with site investigation and clean up,
such as materials, external contractor costs and incremental
internal costs directly related to the remedy. We provide for
expenses associated with environmental remediation obligations
when such amounts are probable and can be reasonably estimated.
We routinely review and evaluate sites that require remediation
and determine our estimated cost for the likely remedy based on
a number of estimates and assumptions.
Where it is probable that a liability has been incurred, we
estimate costs required to remediate sites based on
site-specific facts and circumstances. We routinely review and
evaluate sites that require remediation, considering whether we
were an owner, operator, transporter, or generator at the site,
the amount and type of waste hauled to the site and the number
of years we were associated with the site. Next, we review the
same type of information with respect to other named and unnamed
PRPs. Estimates of the costs for the likely remedy are then
either developed using our internal resources or by third-party
environmental engineers or other service providers. Internally
developed estimates are based on:
Estimating our degree of responsibility for remediation is
inherently difficult. We recognize and accrue for an estimated
remediation liability only when we determine that such liability
is both probable and reasonably estimable. Determining the
method and ultimate cost of remediation requires that a number
of assumptions be made. There can sometimes be a range of
reasonable estimates of the costs associated with the
investigation of the extent of environmental impact and
identification of likely site-remediation alternatives. In these
cases, we use the amount within a range that constitutes our
best estimate. If no amount within the range appears to be a
better estimate than any other, we use the amount that is the
low end of such range. If we used the high ends of such ranges,
our aggregate potential liability would be approximately
$150 million higher than the $284 million recorded in
the Consolidated Financial Statements as of December 31,
2010. Our ultimate responsibility may differ materially from
current estimates. It is possible that technological, regulatory
or enforcement developments, the results of environmental
studies, the inability to identify other PRPs, the inability of
other PRPs to contribute to the settlements of such liabilities,
or other factors could require us to record additional
liabilities. Our ongoing review of our remediation liabilities
could result in revisions to our accruals that could cause
upward or downward adjustments to income from operations. These
adjustments could be material in any given period.
Where we believe that both the amount of a particular
environmental remediation liability and the timing of the
payments are reliably determinable, we inflate the cost in
current dollars (by 2.5% at both December 31, 2010 and
2009) until the expected time of payment and discount the
cost to present value using a risk-free discount rate, which is
based on the rate for United States Treasury bonds with a term
approximating the weighted average period until settlement of
the underlying obligation. We determine the risk-free discount
rate and the inflation rate on an annual basis unless interim
changes would significantly impact our results of operations.
For remedial liabilities that have been discounted, we include
interest accretion, based on the effective interest method, in
“Operating” costs and expenses in our Consolidated
Statements of Operations. The following table summarizes the
impacts of revisions in the risk-free discount rate applied to
our environmental remediation liabilities and recovery assets
during the reported periods (in millions) and the risk-free
discount rate applied as of each reporting date:
The portion of our recorded environmental remediation
liabilities that has never been subject to inflation or
discounting, as the amounts and timing of payments are not
readily determinable, was $81 million at December 31,
2010 and $44 million at December 31, 2009. Had we not
inflated and discounted any portion of our environmental
remediation liability, the amount recorded would have increased
by $15 million and $20 million at December 31,
2010 and 2009, respectively.

Property and Equipment (exclusive of landfills) |
Property
and Equipment (exclusive of landfills, discussed
above)
We record property and equipment at cost. Expenditures for major
additions and improvements are capitalized and maintenance
activities are expensed as incurred. We depreciate property and
equipment over the estimated useful life of the asset using the
straight-line method. We assume no salvage value for our
depreciable property and equipment. When property and equipment
are retired, sold or otherwise disposed of, the cost and
accumulated depreciation are removed from our accounts and any
resulting gain or loss is included in results of operations as
an offset or increase to operating expense for the period.
The estimated useful lives for significant property and
equipment categories are as follows (in years):
We include capitalized costs associated with developing or
obtaining internal-use software within furniture, fixtures and
office equipment. These costs include direct external costs of
materials and services used in developing or obtaining the
software and internal costs for employees directly associated
with the software development project. As of December 31,
2010, capitalized costs for software placed in service, net of
accumulated depreciation, were $44 million. In addition,
our furniture, fixtures and office equipment includes
$51 million as of December 31, 2010 and
$46 million as of December 31, 2009 for costs incurred
for software under development.

||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Leases |
Leases
We lease property and equipment in the ordinary course of our
business. Our most significant lease obligations are for
property and equipment specific to our industry, including real
property operated as a landfill, transfer station or
waste-to-energy
facility. Our leases have varying terms. Some may include
renewal or purchase options, escalation clauses, restrictions,
penalties or other obligations that we consider in determining
minimum lease payments. The leases are classified as either
operating leases or capital leases, as appropriate.
Operating Leases (excluding landfills discussed
below) — The majority of our leases are operating
leases. This classification generally can be attributed to
either (i) relatively low fixed minimum lease payments as a
result of real property lease obligations that vary based on the
volume of waste we receive or process or (ii) minimum lease
terms that are much shorter than the assets’ economic
useful lives. Management expects that in the normal course of
business our operating leases will be renewed, replaced by other
leases, or replaced with fixed asset expenditures. Our rent
expense during each of the last three years and our future
minimum operating lease payments for each of the next five years
for which we are contractually obligated as of December 31,
2010 are disclosed in Note 11.
Capital Leases (excluding landfills discussed
below) — Assets under capital leases are
capitalized using interest rates determined at the inception of
each lease and are amortized over either the useful life of the
asset or the lease term, as appropriate, on a straight-line
basis. The present value of the related lease payments is
recorded as a debt obligation. Our future minimum annual capital
lease payments are included in our total future debt obligations
as disclosed in Note 7.
Landfill Leases — From an operating
perspective, landfills that we lease are similar to landfills we
own because generally we own the landfill’s operating
permit and will operate the landfill for the entire lease term,
which in many cases is the life of the landfill. As a result,
our landfill leases are generally capital leases. The most
significant portion of our rental obligations for landfill
leases is contingent upon operating factors such as disposal
volumes and often there are no contractual minimum rental
obligations. Contingent rental obligations are expensed as
incurred. For landfill capital leases that provide for minimum
contractual rental obligations, we record the present value of
the minimum obligation as part of the landfill asset, which is
amortized on a
units-of-consumption
basis over the shorter of the lease term or the life of the
landfill.

||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Acquisitions |
Acquisitions
We generally recognize assets acquired and liabilities assumed
in business combinations, including contingent assets and
liabilities, based on fair value estimates as of the date of
acquisition.
Contingent Consideration — In certain
acquisitions, we agree to pay additional amounts to sellers
contingent upon achievement by the acquired businesses of
certain negotiated goals, such as targeted revenue levels,
targeted disposal volumes or the issuance of permits for
expanded landfill airspace. For acquisitions completed in 2009
and 2010, we have recognized liabilities for these contingent
obligations based on their estimated fair value at the date of
acquisition with any differences between the acquisition-date
fair value and the ultimate settlement of the obligations being
recognized as an adjustment to income from operations. For
acquisitions completed before 2009, these obligations were
recognized as incurred and accounted for as an adjustment to the
initial purchase price of the acquired assets.
Acquired Assets and Assumed Liabilities —
Assets and liabilities arising from contingencies such as
pre-acquisition environmental matters and litigation are
recognized at their acquisition-date fair value when their
respective fair values can be determined. If the fair values of
such contingencies cannot be determined, they are recognized at
the acquisition date if the contingencies are probable and an
amount can be reasonably estimated. Acquisition-date fair value
estimates are revised as necessary and accounted for as an
adjustment to income from operations if, and when, additional
information regarding these contingencies becomes available to
further define and quantify assets acquired and liabilities
assumed.
Beginning in 2009, all acquisition-related transaction costs
have been expensed as incurred. For acquisitions completed
before 2009, direct costs incurred for a business combination
were accounted for as part of the cost of the acquired business.
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Goodwill and Other Intangible Assets |
Goodwill
and Other Intangible Assets
Goodwill is the excess of our purchase cost over the fair value
of the net assets of acquired businesses. We do not amortize
goodwill, but as discussed in the “Asset Impairments”
section below, we assess our goodwill for impairment at least
annually.
Other intangible assets consist primarily of customer contracts,
customer lists, covenants
not-to-compete,
licenses, permits (other than landfill permits, as all
landfill-related intangible assets are combined with landfill
tangible assets and amortized using our landfill amortization
policy), and other contracts. Other intangible assets are
recorded at cost and are generally amortized using either a 150%
declining balance approach or a straight-line basis as we
determine appropriate. Customer contracts and customer lists are
typically amortized over ten years. Covenants
not-to-compete
are amortized over the term of the non-compete covenant, which
is generally two to five years. Licenses, permits and other
contracts are amortized over the definitive terms of the related
agreements. If the underlying agreement does not contain
definitive terms and the useful life is determined to be
indefinite, the asset is not amortized.
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Asset Impairments |
Asset
Impairments
We monitor the carrying value of our long-lived assets for
potential impairment and test the recoverability of such assets
whenever events or changes in circumstances indicate that their
carrying amounts may not be recoverable. These events or changes
in circumstances are referred to as impairment indicators. If an
impairment indicator occurs, we perform a test of recoverability
by comparing the carrying value of the asset or asset group to
its undiscounted expected future cash flows. If cash flows
cannot be separately and independently identified for a single
asset, we will determine whether an impairment has occurred for
the group of assets for which we can identify the projected cash
flows. If the carrying values are in excess of undiscounted
expected future cash flows, we measure any impairment by
comparing the fair value of the asset or asset group to its
carrying value. Fair value is generally determined by
considering (i) internally developed discounted projected
cash flow analysis of the asset or asset group; (ii) actual
third-party valuations;
and/or
(iii) information available regarding the current market
for similar assets. If the fair value of an asset or asset group
is determined to be less than the carrying amount of the asset
or asset group, an impairment in the amount of the difference is
recorded in the period that the impairment indicator occurs and
is included in the “(Income) expense from divestitures,
asset impairments and unusual items” line item in our
Consolidated Statement of Operations. Estimating future cash
flows requires significant judgment and projections may vary
from the cash flows eventually realized, which could impact our
ability to accurately assess whether an asset has been impaired.
There are additional considerations for impairments of landfills
and goodwill, as described below.
Landfills — Certain impairment indicators
require significant judgment and understanding of the waste
industry when applied to landfill development or expansion
projects. For example, a regulator may initially deny a landfill
expansion permit application though the expansion permit is
ultimately granted. In addition, management may periodically
divert waste from one landfill to another to conserve remaining
permitted landfill airspace. Therefore, certain events could
occur in the ordinary course of business that are not
necessarily considered indicators of impairment of our landfill
assets due to the unique nature of the waste industry.
Goodwill — At least annually, we assess our
goodwill for impairment. We assess whether an impairment exists
by comparing the fair value of each operating segment to its
carrying value, including goodwill. We use a combination of two
valuation methods, a market approach and an income approach, to
estimate the fair value of our operating segments. Fair value
computed by these two methods is arrived at using a number of
factors, including projected future operating results, economic
projections, anticipated future cash flows, comparable
marketplace data and the cost of capital. There are inherent
uncertainties related to these factors and to our judgment in
applying
them to this analysis. However, we believe that these two
methods provide a reasonable approach to estimating the fair
value of our operating segments.
The market approach estimates fair value by measuring the
aggregate market value of publicly-traded companies with similar
characteristics to our business as a multiple of their reported
cash flows. We then apply that multiple to our operating
segments’ cash flows to estimate their fair values. We
believe that this approach is appropriate because it provides a
fair value estimate using valuation inputs from entities with
operations and economic characteristics comparable to our
operating segments.
The income approach is based on the long-term projected future
cash flows of our operating segments. We discount the estimated
cash flows to present value using a weighted-average cost of
capital that considers factors such as the timing of the cash
flows and the risks inherent in those cash flows. We believe
that this approach is appropriate because it provides a fair
value estimate based upon our operating segments’ expected
long-term performance considering the economic and market
conditions that generally affect our business.
Additional impairment assessments may be performed on an interim
basis if we encounter events or changes in circumstances that
would indicate that, more likely than not, the carrying value of
goodwill has been impaired. Refer to Note 6 for additional
information related to goodwill impairment considerations made
during the reported periods.

Restricted Trust and Escrow Accounts |
Restricted
Trust and Escrow Accounts
As of December 31, 2010, our restricted trust and escrow
accounts consist principally of (i) funds deposited for
purposes of settling landfill capping, closure, post-closure and
environmental remediation obligations; and (ii) funds
received from the issuance of tax-exempt bonds held in trust for
the construction of various projects or facilities. As of
December 31, 2010 and 2009, we had $146 million and
$306 million, respectively, of restricted trust and escrow
accounts, which are primarily included in long-term “Other
assets” in our Consolidated Balance Sheets. The decrease in
restricted trust and escrow accounts from December 31, 2009
is due to our implementation of revised accounting guidance
related to the consolidation of variable interest entities.
Additional information can be found in Note 2 and
Note 20.
Capping, Closure, Post-Closure and Environmental Remediation
Funds — At several of our landfills, we provide
financial assurance by depositing cash into restricted trust
funds or escrow accounts for purposes of settling capping,
closure, post-closure and environmental remediation obligations.
Balances maintained in these trust funds and escrow accounts
will fluctuate based on (i) changes in statutory
requirements; (ii) future deposits made to comply with
contractual arrangements; (iii) the ongoing use of funds
for qualifying closure, post-closure and environmental
remediation activities; (iv) acquisitions or divestitures
of landfills; and (v) changes in the fair value of the
financial instruments held in the trust fund or escrow accounts.
Tax-Exempt Bond Funds — We obtain funds from
the issuance of industrial revenue bonds for the construction of
collection and disposal facilities and for equipment necessary
to provide waste management services. Proceeds from these
arrangements are directly deposited into trust accounts, and we
do not have the ability to use the funds in regular operating
activities. Accordingly, these borrowings are treated as
non-cash financing activities and are excluded from our
Consolidated Statements of Cash Flows. As our construction and
equipment expenditures are documented and approved by the
applicable bond trustee, the funds are released and we receive a
cash reimbursement. These cash reimbursements are reported in
the Consolidated Statements of Cash Flows as an investing
activity when the cash is released from the trust funds.
Generally, the funds are fully expended within a few years of
the debt issuance. When the debt matures, we repay our
obligation with cash on hand and the debt repayments are
included as a financing activity in the Consolidated Statements
of Cash Flows.

Foreign Currency |
Foreign
Currency
We have operations in Canada. The functional currency of our
Canadian subsidiaries is Canadian dollars. The assets and
liabilities of our foreign operations are translated to
U.S. dollars using the exchange rate at the balance
sheet date. Revenues and expenses are translated to
U.S. dollars using the average exchange rate during the
period. The resulting translation difference is reflected as a
component of comprehensive income.
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Derivative Financial Instruments |
Derivative
Financial Instruments
We primarily use derivative financial instruments to manage our
risk associated with fluctuations in interest rates, foreign
currency exchange rates and market prices for electricity. We
use interest rate swaps to maintain a strategic portion of our
long-term debt obligations at variable, market-driven interest
rates. In 2009, we entered into interest rate derivatives in
anticipation of senior note issuances planned for 2010 through
2014 to effectively lock in a fixed interest rate for those
anticipated issuances. Foreign currency exchange rate
derivatives are used to hedge our exposure to changes in
exchange rates for anticipated cash transactions between
WM Holdings and its Canadian subsidiaries. We use
electricity commodity derivatives to mitigate the variability in
our revenues and cash flows caused by fluctuations in the market
prices for electricity.
We obtain current valuations of our interest rate, foreign
currency and electricity commodity hedging instruments from
third-party pricing models. The estimated fair values of
derivatives used to hedge risks fluctuate over time and should
be viewed in relation to the underlying hedged transaction and
the overall management of our exposure to fluctuations in the
underlying risks. The fair value of derivatives is included in
other current assets, other long-term assets, accrued
liabilities or other long-term liabilities, as appropriate. Any
ineffectiveness present in either fair value or cash flow hedges
is recognized immediately in earnings without offset. There was
no significant ineffectiveness in 2010, 2009 or 2008.

Insured and Self-Insured Claims |
Insured
and Self-Insured Claims
We have retained a significant portion of the risks related to
our health and welfare, automobile, general liability and
workers’ compensation insurance programs. The exposure for
unpaid claims and associated expenses,
including incurred but not reported losses, generally is
estimated with the assistance of external actuaries and by
factoring in pending claims and historical trends and data. The
gross estimated liability associated with settling unpaid claims
is included in “Accrued liabilities” in our
Consolidated Balance Sheets if expected to be settled within one
year, or otherwise is included in long-term “Other
liabilities.” Estimated insurance recoveries related to
recorded liabilities are reflected as current “Other
receivables” or long-term “Other assets” in our
Consolidated Balance Sheets when we believe that the receipt of
such amounts is probable.

Revenue Recognition |
Revenue
Recognition
Our revenues are generated from the fees we charge for waste
collection, transfer, disposal and recycling services and the
sale of recycled commodities, electricity, steam and landfill
gas. The fees charged for our services are generally defined in
our service agreements and vary based on contract-specific terms
such as frequency of service, weight, volume and the general
market factors influencing a region’s rates. The fees we
charge for our services generally include fuel surcharges, which
are intended to pass through to customers increased direct and
indirect costs incurred because of changes in market prices for
fuel. We generally recognize revenue as services are performed
or products are delivered. For example, revenue typically is
recognized as waste is collected, tons are received at our
landfills or transfer stations, recycling commodities are
delivered or as kilowatts are delivered to a customer by a
waste-to-energy
facility or independent power production plant.
We bill for certain services prior to performance. Such services
include, among others, certain residential contracts that are
billed on a quarterly basis and equipment rentals. These advance
billings are included in deferred revenues and recognized as
revenue in the period service is provided.

were $490 million, $443 million and $472 million,
respectively, of which $17 million in each year was
capitalized. The interest capitalized in 2009 and 2008 was
primarily for landfill construction costs. In 2010, interest was
capitalized primarily for landfill construction costs and
landfill

Income Taxes |
Income
Taxes
The Company is subject to income tax in the United States,
Canada and Puerto Rico. Current tax obligations associated with
our provision for income taxes are reflected in the accompanying
Consolidated Balance Sheets as a component of “Accrued
liabilities,” and the deferred tax obligations are
reflected in “Deferred income taxes.”
Deferred income taxes are based on the difference between the
financial reporting and tax basis of assets and liabilities. The
deferred income tax provision represents the change during the
reporting period in the deferred tax assets and deferred tax
liabilities, net of the effect of acquisitions and dispositions.
Deferred tax assets include tax loss and credit carry-forwards
and are reduced by a valuation allowance if, based on available
evidence, it is more likely than not that some portion or all of
the deferred tax assets will not be realized. Significant
judgment is required in assessing the timing and amounts of
deductible and taxable items. We establish reserves for
uncertain tax positions when, despite our belief that our tax
return positions are fully supportable, we believe that certain
positions may be challenged and potentially disallowed. When
facts and circumstances change, we adjust these reserves through
our provision for income taxes.
To the extent interest and penalties may be assessed by taxing
authorities on any underpayment of income tax, such amounts have
been accrued and are classified as a component of income tax
expense in our Consolidated Statements of Operations.

We are party to pending or threatened legal proceedings covering
a wide range of matters in various jurisdictions. It is
difficult to predict the outcome of litigation, as it is subject
to many uncertainties. Additionally, it is not always possible
for management to make a meaningful estimate of the potential
loss or range of loss associated with such contingencies.

A description of a company's cash and cash equivalents accounting policy. An entity shall disclose its policy for determining which items are treated as cash equivalents. Other information that may be disclosed includes (1) the nature of any restrictions on the entity's use of its cash and cash equivalents, (2) whether the entity's cash and cash equivalents are insured or expose the entity to credit risk, (3) the classification of any negative balance accounts (overdrafts), and (4) the carrying basis of cash equivalents (for example, at cost) and whether the carrying amount of cash equivalents approximates fair value. Cash includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the customer may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. In addition, cash equivalents include short-term, highly liquid investments that are both readily convertible to known amounts of cash and so near their maturity that they present insignificant risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three-years ago does not become a cash equivalent when its remaining maturity is three months. For a bank, may include explanation and amount of requirement to maintain reserves against deposits. Reference 1: http://www.xbrl.org/2003/role/presentationRef

For defined benefit pension plans, the actuarial present value of benefits (whether vested or nonvested) attributed by the pension benefit formula to employee service rendered before a specified date and based on employee service and compensation (if applicable) before that date. The accumulated benefit obligation differs from the projected benefit obligation in that it includes no assumption about future compensation levels. For plans with flat-benefit or nonpay-related pension benefit formulas, the accumulated benefit obligation and the projected benefit obligation are the same.

- Definition
Includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Entity may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits should not be reported as cash and cash equivalents.

The sum of adjustments which are added to or deducted from net income or loss, including the portion attributable to noncontrolling interest, to reflect cash provided by or used in operating activities, in accordance with the indirect cash flow method.

- Definition
Includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Entity may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits should not be reported as cash and cash equivalents.
