Insolvency Assessments Most of the jurisdictions in which the Company is admitted to transact business require insurers doing business within the jurisdiction to participate in guaranty associations, which are organized to pay contractual benefits owed pursuant to insurance policies issued by impaired, insolvent or failed insurers.
These associations levy assessments, up to prescribed limits, on all member insurers in a particular state on the basis of the proportionate share of the premiums written by member insurers in the lines of business in which the impaired, insolvent or failed insurer engaged.
Some states permit member insurers to recover assessments paid through full or partial premium tax offsets.
Assets and liabilities held for insolvency assessments are as follows:

Assessments levied against the Company were $2 million, ($1) million and $2 million for the years ended December 31, 2008, 2007 and 2006, respectively.
Effects of Inflation The Company does not believe that inflation has had a material effect on its consolidated results of operations, except insofar as inflation may affect interest rates.
Inflation in the United States has remained contained and been in a general downtrend for an extended period.
However, in light of recent and ongoing aggressive fiscal and monetary stimulus measures by the U. S.  federal government and foreign governments, it is possible that inflation could increase in the future.
An increase in inflation could affect our business in several ways.
During inflationary periods, the value of fixed income investments falls which could increase realized and unrealized losses.
Inflation also increases expenses for labor and other materials, potentially putting pressure on profitability if such costs can not be passed through in our product prices.
Inflation could also lead to increased costs for losses and loss adjustment expenses in our Auto & Home business, which could require us to adjust our pricing to reflect our expectations for future inflation.
If actual inflation exceeds the expectations we use in pricing our policies, the profitability of our Auto & Home business would be adversely affected.
Prolonged and elevated inflation could adversely affect the financial markets and the economy generally, and dispelling it may require governments to pursue a restrictive fiscal and monetary policy, which could constrain overall economic activity, inhibit revenue growth and reduce the number of attractive investment opportunities.
Adoption of New Accounting Pronouncements Fair Value Effective January 1, 2008, the Company adopted SFAS No.157, Fair Value Measurements.
SFAS 157 which defines fair value, establishes a consistent framework for measuring fair value, establishes a fair value hierarchy based on the observability of inputs used to measure fair value, and requires enhanced disclosures about fair value measurements and applied the provisions of the statement prospectively to assets and liabilities measured at fair value.
The adoption of SFAS 157 changed the valuation of certain freestanding derivatives by moving from a mid to bid pricing convention as it relates to certain volatility inputs as well as the addition of liquidity adjustments and adjustments for risks inherent in a particular input or valuation technique.
The adoption of SFAS 157 also changed the valuation of the Company’s embedded derivatives, most significantly the valuation of embedded derivatives associated with certain riders on variable annuity contracts.
The change in valuation of embedded derivatives associated with riders on annuity contracts resulted from the incorporation of risk margins associated with non capital market inputs and the inclusion of the Company’s own credit standing in their valuation.
At January 1, 2008, the impact of adopting SFAS 157 on assets and liabilities measured at estimated fair value was $30 million ($19 million, net of income tax) and was recognized as a change in estimate in the accompanying consolidated statement of income where it was presented in the respective income statement caption to which the item measured at estimated fair value is presented.
There were no significant changes in estimated fair value of items measured at fair value and reflected in accumulated other comprehensive income (loss).
The addition of risk margins and the Company’s own credit spread in the valuation of embedded derivatives associated with annuity contracts may result in significant volatility in the Company’s consolidated net income in future periods.
Note 24 of the Notes to the
At December 31, 2008 and 2007, the Company’s gross unrealized losses related to its fixed maturity and equity securities of $29.8 billion and $4.7 billion, respectively, were concentrated, calculated as a percentage of gross unrealized loss, as follows:
## Table 2 ##
Writedowns.
The components of fixed maturity and equity securities net investment gains (losses) are as follows:
## Table 3 ##
(1) Other than credit-related writedowns include items such as equity securities where the primary reason for the writedown was the severity and/or the duration of an unrealized loss position and fixed maturity securities where an interest-rate related writedown was taken.
Overview of Fixed Maturity and Equity Security Writedowns.
Writedowns of fixed maturity and equity securities were $1.7 billion, $97 million and $80 million for the years ended December 31, 2008, 2007 and 2006, respectively.
Writedowns of fixed maturity securities were $1.3 billion, $78 million and $56 million for the years ended December 31, 2008, 2007 and 2006, respectively.
Writedowns of equity securities were $430 million, $19 million and $24 million for the years ended December 31, 2008, 2007 and 2006, respectively.
The Company’s credit-related writedowns of fixed maturity and equity securities were $1.2 billion, $77 million and $80 million for the years ended December 31, 2008, 2007 and 2006, respectively.
The Company’s credit-related writedowns of fixed maturity securities were $1.1 billion, $58 million and $56 million for the years ended December 31, 2008, 2007 and 2006, respectively.
The Company’s creditrelated writedowns of equity securities were $90 million, $19 million and $24 million for the years ended December 31, 2008, 2007 and 2006, respectively.
The $90 million of credit-related equity securities writedowns in 2008 were primarily on non-redeemable preferred securities.
The Company’s three largest impairments totaled $528 million, $19 million and $33 million for the years ended December 31, 2008, 2007 and 2006, respectively.
The Company records impairments as investment losses and adjusts the cost basis of the fixed maturity and equity securities accordingly.
The Company does not change the revised cost basis for subsequent recoveries in value.
Failure to comply with the financial and other covenants under our Credit Facilities, as well as the occurrence of certain material adverse events, would constitute defaults and would allow the lenders under our Credit Facilities to accelerate the maturity of all indebtedness under the related agreements.
This could also have an adverse impact on the availability of financial assurances.
In addition, maturity acceleration on our Credit Facilities constitutes an event of default under our other debt instruments, including our senior notes, and, therefore, our senior notes would also be subject to acceleration of maturity.
If such acceleration were to occur, we would not have sufficient liquidity available to repay the indebtedness.
We would likely have to seek an amendment under our Credit Facilities for relief from the financial covenants or repay the debt with proceeds from the issuance of new debt or equity, or asset sales, if necessary.
We may be unable to amend our Credit Facilities or raise sufficient capital to repay such obligations in the event the maturities are accelerated.
Financial assurance We are required to provide financial assurance to governmental agencies and a variety of other entities under applicable environmental regulations relating to our landfill operations for capping, closure and post-closure costs, and related to our performance under certain collection, landfill and transfer station contracts.
We satisfy these financial assurance requirements by providing surety bonds, letters of credit, insurance policies or trust deposits.
The amount of the financial assurance requirements for capping, closure and post-closure costs is determined by applicable state environmental regulations.
The financial assurance requirements for capping, closure and post-closure costs may be associated with a portion of the landfill or the entire landfill.
Generally, states will require a third-party engineering specialist to determine the estimated capping, closure and postclosure costs that are used to determine the required amount of financial assurance for a landfill.
The amount of financial assurance required can, and generally will, differ from the obligation determined and recorded under U. S.  GAAP.
The amount of the financial assurance requirements related to contract performance varies by contract.
Additionally, we are required to provide financial assurance for our insurance program and collateral for certain performance obligations.
We do not expect a material increase in financial assurance requirements during 2010, although the mix of financial assurance instruments may change.
These financial instruments are issued in the normal course of business and are not debt of our company.
Since we currently have no liability for these financial assurance instruments, they are not reflected in our consolidated balance sheets.
However, we record capping, closure and post-closure liabilities and self-insurance liabilities as they are incurred.
The underlying obligations of the financial assurance instruments, in excess of those already reflected in our consolidated balance sheets, would be recorded if it is probable that we would be unable to fulfill our related obligations.
We do not expect this to occur.
Off-Balance Sheet Arrangements We have no off-balance sheet debt or similar obligations, other than financial assurance instruments and operating leases that are not classified as debt.
We do not guarantee any third-party debt.
Free Cash Flow We define free cash flow, which is not a measure determined in accordance with U. S.  GAAP, as cash provided by operating activities less purchases of property and equipment, plus proceeds from sales of property and equipment as presented in our consolidated statements of cash flows.
Our free cash flow for the years ended December 31, 2009, 2008 and 2007 is calculated as follows (in millions):
