(1) Certain amounts above have been reclassified to conform to the current year’s presentation.
We believe that it is more likely than not that the benefit from certain state net operating loss carryforwards will not be realized.
In recognition of this risk, we have provided a valuation allowance of $156.4 million on deferred tax assets relating to these state net operating loss carryforwards.
In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized after the initial recognition of the deferred tax asset.
We provide valuation allowances, as needed, to offset portions of deferred tax assets due to uncertainty surrounding the future realization of such deferred tax assets.
We adjust the valuation allowance in the period management determines it is more likely than not that deferred tax assets will or will not be realized.
We have recorded $107.1 million of deferred tax assets and $774.1 million of deferred income taxes and other long-term tax liabilities as part of our preliminary purchase price allocation for our acquisition of Allied.
This allocation is subject to change until we finalize our valuations and other estimates in 2009.

OTHER COMPREHENSIVE INCOME Fuel Hedges We have entered into multiple option agreements related to forecasted diesel fuel purchases.
Under SFAS 133, the options qualified for, and were designated as, effective hedges of changes in the prices of forecasted diesel fuel purchases (fuel hedges).
The following table summarizes our outstanding fuel hedges at December 31, 2008 and 2007:
## Table 2 ##
If the national U. S.  on-highway average price for a gallon of diesel fuel (average price) as published by the Department of Energy exceeds the contract price per gallon, we receive the difference between the average price and the contract price (multiplied by the notional gallons) from the counter-party.
If the national U. S.  on-highway average price for a gallon of diesel fuel is less than the contract price per gallon, we pay the difference to the counter-party.
The fair values of the fuel hedges are obtained from third-party counter-parties and are determined using standard option valuation models with assumptions about commodity prices being based on those observed in underlying markets (Level 2 in the fair value hierarchy).
The aggregated fair values of the outstanding fuel hedges at December 31, 2008 and 2007 were $11.7 million and $11.4 million, respectively, and have been recorded in other current liabilities and other current assets in our consolidated balance sheets, respectively.

REPUBLIC SERVICES, INC.  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued) high quality financial institutions.
Such balances may be in excess of FDIC insured limits.
To manage the related credit exposure, we continually monitor the credit worthiness of the financial institutions where we have deposits.
Concentrations of credit risk with respect to trade accounts receivable are limited due to the wide variety of customers and markets in which we provide services, as well as the dispersion of our operations across many geographic areas.
We provide services to commercial, industrial, municipal and residential customers in the United States and Puerto Rico.
We perform ongoing credit evaluations of our customers, but do not require collateral to support customer receivables.
We establish an allowance for doubtful accounts based on various factors including the credit risk of specific customers, age of receivables outstanding, historical trends, economic conditions and other information.
No customer exceeded 5% of our outstanding accounts receivable balance at December 31, 2012 and 2011.
Accounts Receivable, Net of Allowance for Doubtful Accounts Accounts receivable represent receivables from customers for collection, transfer, recycling, disposal and other services.
Our receivables are recorded when billed or when the related revenue is earned, if earlier, 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 their estimated net realizable value.
Provisions for doubtful accounts are evaluated on a monthly basis and are recorded based on our historical collection experience, the age of the receivables, specific customer information and economic conditions.
We also review outstanding balances on an account-specific basis.
In general, reserves are provided for accounts receivable in excess of ninety days old.
Past due receivable balances are written-off when our collection efforts have been unsuccessful in collecting amounts due.
The following table reflects the activity in our allowance for doubtful accounts for the years ended December 31, 2012, 2011 and 2010:

Restricted Cash and Marketable Securities As of December 31, 2012, we had $164.2 million of restricted cash and marketable securities.
We obtain funds through the issuance of tax-exempt bonds for the purpose of financing qualifying expenditures at our landfills, transfer stations, collection and recycling centers.
The funds are deposited directly into trust accounts by the bonding authorities at the time of issuance.
As the use of these funds is contractually restricted, and we do not have the ability to use these funds for general operating purposes, they are classified as restricted cash and marketable securities in our consolidated balance sheets.
In the normal course of business, we may be required to provide financial assurance to governmental agencies and a variety of other entities in connection with municipal residential collection contracts, closure or postclosure of landfills, environmental remediation, environmental permits, and business licenses and permits as a financial guarantee of our performance.
At several of our landfills, we satisfy financial assurance requirements by depositing cash into restricted trust funds or escrow accounts.
