HUMANA INC | 2013 | FY | 3


2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

Our financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America. Our consolidated financial statements include the accounts of Humana Inc. and subsidiaries that the Company controls, including variable interest entities associated with medical practices for which we are the primary beneficiary. We do not own many of our medical practices but instead enter into exclusive long-term management agreements with the affiliated Professional Associations, or P.A.s, that operate these medical practices. Based upon the provisions of these agreements, these affiliated P.A.s are variable interest entities and we are the primary beneficiary, and accordingly we consolidated the affiliated P.A.s. All significant intercompany balances and transactions have been eliminated.

The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires us to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The areas involving the most significant use of estimates are the estimation of benefits payable, future policy benefits payable, the impact of risk sharing provisions related to our Medicare contracts, the valuation and related impairment recognition of investment securities, and the valuation and related impairment recognition of long-lived assets, including goodwill. These estimates are based on knowledge of current events and anticipated future events, and accordingly, actual results may ultimately differ materially from those estimates.

Business Segment Reclassifications

On January 1, 2013, we reclassified certain of our businesses to correspond with internal management reporting changes and renamed our Health and Well-Being Services segment as Healthcare Services. Our Employer Group segment now includes our health and wellness businesses, including HumanaVitality and Lifesynch’s employee assistance programs, which had historically been reported in our Healthcare Services segment. The Retail segment now includes our contract with the Centers for Medicare and Medicaid Services, or CMS, to administer the Limited Income Newly Eligible Transition, or LI-NET, prescription drug plan program as well as our state-based contracts for Medicaid members, both of which had historically been reported in our Other Businesses category. Prior period segment financial information has been recast to conform to the 2013 presentation. See Note 16 for segment financial information.

Cash and Cash Equivalents

Cash and cash equivalents include cash, time deposits, money market funds, commercial paper, other money market instruments, and certain U.S. Government securities with an original maturity of three months or less. Carrying value approximates fair value due to the short-term maturity of the investments.

Investment Securities

Investment securities, which consist entirely of debt securities, have been categorized as available for sale and, as a result, are stated at fair value. Investment securities available for current operations are classified as current assets. Investment securities available for our long-term insurance products and professional liability funding requirements, as well as restricted statutory deposits, are classified as long-term assets. For the purpose of determining gross realized gains and losses, which are included as a component of investment income in the consolidated statements of income, the cost of investment securities sold is based upon specific identification. Unrealized holding gains and losses, net of applicable deferred taxes, are included as a component of stockholders’ equity and comprehensive income until realized from a sale or other-than-temporary impairment.

Under the other-than-temporary impairment model for debt securities held, we recognize an impairment loss in income in an amount equal to the full difference between the amortized cost basis and the fair value when we have the intent to sell the debt security or it is more likely than not we will be required to sell the debt security before recovery of our amortized cost basis. However, if we do not intend to sell the debt security, we evaluate the expected cash flows to be received as compared to amortized cost and determine if a credit loss has occurred. In the event of a credit loss, only the amount of the impairment associated with the credit loss is recognized currently in income with the remainder of the loss recognized in other comprehensive income.

When we do not intend to sell a security in an unrealized loss position, potential other-than-temporary impairment is considered using a variety of factors, including the length of time and extent to which the fair value has been less than cost; adverse conditions specifically related to the industry, geographic area or financial condition of the issuer or underlying collateral of a security; payment structure of the security; changes in credit rating of the security by the rating agencies; the volatility of the fair value changes; and changes in fair value of the security after the balance sheet date. For debt securities, we take into account expectations of relevant market and economic data. For example, with respect to mortgage and asset-backed securities, such data includes underlying loan level data and structural features such as seniority and other forms of credit enhancements. A decline in fair value is considered other-than-temporary when we do not expect to recover the entire amortized cost basis of the security. We estimate the amount of the credit loss component of a debt security as the difference between the amortized cost and the present value of the expected cash flows of the security. The present value is determined using the best estimate of future cash flows discounted at the implicit interest rate at the date of purchase.

Receivables and Revenue Recognition

We generally establish one-year commercial membership contracts with employer groups, subject to cancellation by the employer group on 30-day written notice. Our Medicare contracts with CMS renew annually. Our military services contracts with the federal government and our contracts with various state Medicaid programs generally are multi-year contracts subject to annual renewal provisions.

Premiums Revenue

We bill and collect premium remittances from employer groups and members in our Medicare and other individual products monthly. We receive monthly premiums from the federal government and various states according to government specified payment rates and various contractual terms. Changes in revenues from CMS for our Medicare products resulting from the periodic changes in risk-adjustment scores derived from medical diagnoses for our membership are recognized when the amounts become determinable and the collectibility is reasonably assured.

Premiums revenue is estimated by multiplying the membership covered under the various contracts by the contractual rates. Premiums revenue is recognized as income in the period members are entitled to receive services, and is net of estimated uncollectible amounts, retroactive membership adjustments, and adjustments to recognize rebates under the minimum benefit ratios required under the Health Care Reform Law. We estimate policyholder rebates by projecting calendar year minimum benefit ratios for the individual, small group, and large group markets, as defined by the Health Care Reform Law using a methodology prescribed by the Department of Health and Human Services, separately by state and legal entity. Beginning in 2014, Medicare Advantage are also subject to minimum benefit ratio requirements under the Health Care Reform Law. Estimated calendar year rebates recognized ratably during the year are revised each period to reflect current experience. Retroactive membership adjustments result from enrollment changes not yet processed, or not yet reported by an employer group or the government. We routinely monitor the collectibility of specific accounts, the aging of receivables, historical retroactivity trends, estimated rebates, as well as prevailing and anticipated economic conditions, and reflect any required adjustments in current operations. Premiums received prior to the service period are recorded as unearned revenues.

Medicare Part D

We cover prescription drug benefits in accordance with Medicare Part D under multiple contracts with CMS. The payments we receive monthly from CMS and members, which are determined from our annual bid, represent amounts for providing prescription drug insurance coverage. We recognize premiums revenue for providing this insurance coverage ratably over the term of our annual contract. Our CMS payment is subject to risk sharing through the Medicare Part D risk corridor provisions. In addition, receipts for reinsurance and low-income cost subsidies as well as receipts for certain discounts on brand name prescription drugs in the coverage gap represent payments for prescription drug costs for which we are not at risk.

The risk corridor provisions compare costs targeted in our bids to actual prescription drug costs, limited to actual costs that would have been incurred under the standard coverage as defined by CMS. Variances exceeding certain thresholds may result in CMS making additional payments to us or require us to refund to CMS a portion of the premiums we received. As risk corridor provisions are considered in our overall annual bid process, we estimate and recognize an adjustment to premiums revenue related to these provisions based upon pharmacy claims experience to date as if the annual contract were to terminate at the end of the reporting period. Accordingly, this estimate provides no consideration to future pharmacy claims experience. We record a receivable or payable at the contract level and classify the amount as current or long-term in the consolidated balance sheets based on the timing of expected settlement.

Reinsurance and low-income cost subsidies represent funding from CMS in connection with the Medicare Part D program for which we assume no risk. Reinsurance subsidies represent funding from CMS for its portion of prescription drug costs which exceed the member’s out-of-pocket threshold, or the catastrophic coverage level. Low-income cost subsidies represent funding from CMS for all or a portion of the deductible, the coinsurance and co-payment amounts above the out-of-pocket threshold for low-income beneficiaries. Monthly prospective payments from CMS for reinsurance and low-income cost subsidies are based on assumptions submitted with our annual bid. A reconciliation and related settlement of CMS’s prospective subsidies against actual prescription drug costs we paid is made after the end of the year. The Health Care Reform Law mandates consumer discounts of 50% on brand name prescription drugs for Part D plan participants in the coverage gap. These discounts are funded by CMS and pharmaceutical manufacturers while we administer the application of these funds. We account for these subsidies and discounts as a deposit in our consolidated balance sheets and as a financing activity in our consolidated statements of cash flows. We do not recognize premiums revenue or benefit expenses for these subsidies or discounts. Receipt and payment activity is accumulated at the contract level and recorded in our consolidated balance sheets in other current assets or trade accounts payable and accrued expenses depending on the contract balance at the end of the reporting period.

Settlement of the reinsurance and low-income cost subsidies as well as the risk corridor payment is based on a reconciliation made approximately 9 months after the close of each calendar year. Settlement with CMS for brand name prescription drug discounts is based on a reconciliation made approximately 14 to 18 months after the close of each calendar year. We continue to revise our estimates with respect to the risk corridor provisions based on subsequent period pharmacy claims data. See Note 6 for detail regarding amounts recorded to the consolidated balance sheets related to the risk corridor settlement and subsidies from CMS.

Military services

Military services premiums and services revenue primarily is derived from our TRICARE South Region contract with the Department of Defense, or DoD. On April 1, 2012, we began delivering services under the current TRICARE South Region contract with the DoD. Under the current contract, we provide administrative services, including offering access to our provider networks and clinical programs, claim processing, customer service, enrollment, and other services, while the federal government retains all of the risk of the cost of health benefits. Under the terms of the current TRICARE South Region contract, we do not record premiums revenue or benefits expense in our consolidated statements of income related to these health care costs and related reimbursements. Instead, we account for revenues under the current contract net of estimated health care costs similar to an administrative services fee only agreement.

Our TRICARE members are served by both in-network and out-of-network providers in accordance with the current contract. We pay health care costs related to these services to the providers and are subsequently reimbursed by the DoD for such payments. We account for the payments of the federal government’s claims and the related reimbursements under deposit accounting in our consolidated balance sheets and as a financing activity under receipts (withdrawals) from contract deposits in our consolidated statements of cash flows. For the first nine months of the current contract, April 1, 2012 to December 31, 2012, health care cost payments were $2.1 billion, exceeding reimbursements of $2.0 billion by $56 million. For 2013, health care cost reimbursements were $3.2 billion, exceeding payments of $3.2 billion by $5 million.

Our previous TRICARE South Region contract that expired on March 31, 2012 provided a financial interest in the underlying health care cost; therefore, we reported revenues on a gross basis. We shared the risk with the federal government for the cost of health benefits incurred under our previous contract, earning more revenue or incurring additional cost based on the variance of actual health care costs from an annually negotiated target health care cost. TRICARE revenues consisted generally of (1) an insurance premium for assuming underwriting risk for the cost of civilian health care services delivered to eligible beneficiaries; (2) health care services provided to beneficiaries which were in turn reimbursed by the federal government; and (3) administrative services fees related to claim processing, customer service, enrollment, and other services. We recognized the insurance premium as revenue ratably over the period coverage was provided. Health care services reimbursements were recognized as revenue in the period health services were provided. Administrative services fees were recognized as revenue in the period services were performed. We deferred the recognition of any contingent revenues for favorable variances until the end of the contract period when the amount was determinable and the collectibility was reasonably assured. We estimated and recognized contingent benefits expense for unfavorable variances currently in our results of operations.

Services Revenue

Patient services revenue

Patient services include workers’ compensation injury care and related services as well as other healthcare services related to employer needs or statutory requirements. Patient services revenues are recognized in the period services are provided to the customer when the sales price is fixed or determinable, and are net of contractual allowances.

Administrative services fees

Administrative services fees cover the processing of claims, offering access to our provider networks and clinical programs, and responding to customer service inquiries from members of self-funded groups. Revenues from providing administration services, also known as administrative services only, or ASO, are recognized in the period services are performed and are net of estimated uncollectible amounts. ASO fees are estimated by multiplying the membership covered under the various contracts by the contractual rates. Under ASO contracts, self-funded employers retain the risk of financing substantially all of the cost of health benefits. However, many ASO customers purchase stop loss insurance coverage from us to cover catastrophic claims or to limit aggregate annual costs. Accordingly, we have recorded premiums revenue and benefits expense related to these stop loss insurance contracts. We routinely monitor the collectibility of specific accounts, the aging of receivables, as well as prevailing and anticipated economic conditions, and reflect any required adjustments in current operations. ASO fees received prior to the service period are recorded as unearned revenues.

On April 1, 2012, we began delivering services under our current TRICARE South Region contract with the DoD. As discussed previously, under the current contract, we provide administrative services, including offering access to our provider networks and clinical programs, claim processing, customer service, enrollment, and other services, while the federal government retains all of the risk of the cost of health benefits. We account for revenues under the current contract net of estimated health care costs similar to an administrative services fee only agreement. The current contract includes fixed administrative services fees and incentive fees and penalties. Administrative services fees are recognized as services are performed.

 

Receivables

Receivables, including premium receivables, patient services revenue receivables, and ASO fee receivables, are shown net of allowances for estimated uncollectible accounts, retroactive membership adjustments, and contractual allowances.

Policy Acquisition Costs

Policy acquisition costs are those costs that relate directly to the successful acquisition of new and renewal insurance policies. Such costs include commissions, costs of policy issuance and underwriting, and other costs we incur to acquire new business or renew existing business. We expense policy acquisition costs related to our employer-group prepaid health services policies as incurred. These short-duration employer-group prepaid health services policies typically have a one-year term and may be cancelled upon 30 days notice by the employer group.

Life insurance, annuities, and certain health and other supplemental policies sold to individuals are accounted for as long-duration insurance products because they are expected to remain in force for an extended period beyond one year and premium received in the earlier years is intended to pay anticipated benefits to be incurred in future yearsAs a result, we defer policy acquisition costs, primarily consisting of commissions, and amortize them over the estimated life of the policies in proportion to premiums earned. Deferred acquisition costs are reviewed to determine if they are recoverable from future income. See Note 17.

Beginning in 2014, health policies sold to individuals that conform to the Health Care Reform Law are accounted for under a short-duration model and accordingly policy acquisition costs are expensed as incurred because premiums received in the current year are intended to pay anticipated benefits in that year.

Long-Lived Assets

Property and equipment is recorded at cost. Gains and losses on sales or disposals of property and equipment are included in operating costs. Certain costs related to the development or purchase of internal-use software are capitalized. Depreciation is computed using the straight-line method over estimated useful lives ranging from 3 to 10 years for equipment, 3 to 7 years for computer software, and 20 to 40 years for buildings. Improvements to leased facilities are depreciated over the shorter of the remaining lease term or the anticipated life of the improvement.

We periodically review long-lived assets, including property and equipment and other intangible assets, for impairment whenever adverse events or changes in circumstances indicate the carrying value of the asset may not be recoverable. Losses are recognized for a long-lived asset to be held and used in our operations when the undiscounted future cash flows expected to result from the use of the asset are less than its carrying value. We recognize an impairment loss based on the excess of the carrying value over the fair value of the asset. A long-lived asset held for sale is reported at the lower of the carrying amount or fair value less costs to sell. Depreciation expense is not recognized on assets held for sale. Losses are recognized for a long-lived asset to be abandoned when the asset ceases to be used. In addition, we periodically review the estimated lives of all long-lived assets for reasonableness.

Goodwill and Other Intangible Assets

Goodwill represents the unamortized excess of cost over the fair value of the net tangible and other intangible assets acquired. We are required to test at least annually for impairment at a level of reporting referred to as the reporting unit, and more frequently if adverse events or changes in circumstances indicate that the asset may be impaired. A reporting unit either is our operating segments or one level below the operating segments, referred to as a component, which comprise our reportable segments. A component is considered a reporting unit if the component constitutes a business for which discrete financial information is available that is regularly reviewed by management. We aggregate the components of an operating segment into one reporting unit if they have similar economic characteristics. Goodwill is assigned to the reporting unit that is expected to benefit from a specific acquisition.

We use a two-step process to review goodwill for impairment. The first step is a screen for potential impairment, and the second step measures the amount of impairment, if any. Impairment tests are performed, at a minimum, in the fourth quarter of each year supported by our long-range business plan and annual planning process. We rely on an evaluation of future discounted cash flows to determine fair value of our reporting units. Impairment tests completed for 2013, 2012, and 2011 did not result in an impairment loss.

Other intangible assets primarily relate to acquired customer contracts/relationships and are included with other long-term assets in the consolidated balance sheets. Other intangible assets are amortized over the useful life, based upon the pattern of future cash flows attributable to the asset. This sometimes results in an accelerated method of amortization for customer contracts because the asset tends to dissipate at a more rapid rate in earlier periods. Other than customer contracts, other intangible assets generally are amortized using the straight-line method. We review other finite-lived intangible assets for impairment under our long-lived asset policy.

Benefits Payable and Benefits Expense Recognition

Benefits expense includes claim payments, capitation payments, pharmacy costs net of rebates, allocations of certain centralized expenses and various other costs incurred to provide health insurance coverage to members, as well as estimates of future payments to hospitals and others for medical care and other supplemental benefits provided prior to the balance sheet date. Capitation payments represent monthly contractual fees disbursed to primary care and other providers who are responsible for providing medical care to members. Pharmacy costs represent payments for members’ prescription drug benefits, net of rebates from drug manufacturers. Receivables for such pharmacy rebates are included in other current assets in the consolidated balance sheets. Other supplemental benefits include dental, vision, and other supplemental health and financial protection products.

We estimate the costs of our benefits expense payments using actuarial methods and assumptions based upon claim payment patterns, medical cost inflation, historical developments such as claim inventory levels and claim receipt patterns, and other relevant factors, and record benefit reserves for future payments. We continually review estimates of future payments relating to claims costs for services incurred in the current and prior periods and make necessary adjustments to our reserves.

We reassess the profitability of our contracts for providing insurance coverage to our members when current operating results or forecasts indicate probable future losses. We establish a premium deficiency liability in current operations to the extent that the sum of expected future costs, claim adjustment expenses, and maintenance costs exceeds related future premiums under contracts without consideration of investment income. For purposes of determining premium deficiencies, contracts are grouped in a manner consistent with our method of acquiring, servicing, and measuring the profitability of such contracts. Losses recognized as a premium deficiency result in a beneficial effect in subsequent periods as operating losses under these contracts are charged to the liability previously established. Because the majority of our member contracts renew annually, we do not anticipate recording a material premium deficiency liability, except when unanticipated adverse events or changes in circumstances indicate otherwise.

We believe our benefits payable are adequate to cover future claims payments required. However, such estimates are based on knowledge of current events and anticipated future events. Therefore, the actual liability could differ materially from the amounts provided.

 

Future policy benefits payable

Future policy benefits payable include liabilities for long-duration insurance policies including long-term care, life insurance, annuities, and certain health and other supplemental policies sold to individuals for which some of the premium received in the earlier years is intended to pay anticipated benefits to be incurred in future years. At policy issuance, these reserves are recognized on a net level premium method based on interest rates, mortality, morbidity, and maintenance expense assumptions. Interest rates are based on our expected net investment returns on the investment portfolio supporting the reserves for these blocks of business. Mortality, a measure of expected death, and morbidity, a measure of health status, assumptions are based on published actuarial tables, modified based upon actual experience. Changes in estimates of these reserves are recognized as an adjustment to benefits expense in the period the changes occur. We perform loss recognition tests at least annually in the fourth quarter, and more frequently if adverse events or changes in circumstances indicate that the level of the liability, together with the present value of future gross premiums, may not be adequate to provide for future expected policy benefits and maintenance costs. We adjust future policy benefits payable for the additional liability that would have been recorded if investment securities backing the liability had been sold at their stated aggregate fair value and the proceeds reinvested at current yields. We include the impact of this adjustment, if any, net of applicable deferred taxes, with the change in unrealized investment gain (loss) in accumulated other comprehensive income in stockholders’ equity. As discussed above, beginning in 2014, health policies sold to individuals that conform to the Health Care Reform Law are accounted for under a short-duration model under which policy reserves are not established because premiums received in the current year are intended to pay anticipated benefits in that year.

Book Overdraft

Under our cash management system, checks issued but not yet presented to banks that would result in negative bank balances when presented are classified as a current liability in the consolidated balance sheets. Changes in book overdrafts from period to period are reported in the consolidated statement of cash flows as a financing activity.

Income Taxes

We recognize an asset or liability for the deferred tax consequences of temporary differences between the tax bases of assets or liabilities and their reported amounts in the consolidated financial statements. These temporary differences will result in taxable or deductible amounts in future years when the reported amounts of the assets or liabilities are recovered or settled. We also recognize the future tax benefits such as net operating and capital loss carryforwards as deferred tax assets. A valuation allowance is provided against these deferred tax assets if it is more likely than not that some portion or all of the deferred tax assets will not be realized. Future years’ tax expense may be increased or decreased by adjustments to the valuation allowance or to the estimated accrual for income taxes.

We record tax benefits when it is more likely than not that the tax return position taken with respect to a particular transaction will be sustained. A liability, if recorded, is not considered resolved until the statute of limitations for the relevant taxing authority to examine and challenge the tax position has expired, or the tax position is ultimately settled through examination, negotiation, or litigation. We classify interest and penalties associated with uncertain tax positions in our provision for income taxes.

Derivative Financial Instruments

At times, we may use interest-rate swap agreements to manage our exposure to interest rate risk. The differential between fixed and variable rates to be paid or received is accrued and recognized over the life of the agreements as adjustments to interest expense in the consolidated statements of income. We were not party to any interest-rate swap agreements in 2013, 2012, or 2011.

 

Stock-Based Compensation

We generally recognize stock-based compensation expense, as determined on the date of grant at fair value, on a straight-line basis over the period during which an employee is required to provide service in exchange for the award (the vesting period). However, for awards granted to retirement eligible employees, the compensation expense is recognized on a straight-line basis over the shorter of the requisite service period or the period from the date of grant to an employee’s eligible retirement date. We estimate expected forfeitures and recognize compensation expense only for those awards which are expected to vest. We estimate the grant-date fair value of stock options using the Black-Scholes option-pricing model. In addition, we report certain tax effects of stock-based compensation as a financing activity rather than an operating activity in the consolidated statement of cash flows. Additional detail regarding our stock-based compensation plans is included in Note 12.

Earnings Per Common Share

We compute basic earnings per common share on the basis of the weighted-average number of unrestricted common shares outstanding. Diluted earnings per common share is computed on the basis of the weighted-average number of unrestricted common shares outstanding plus the dilutive effect of outstanding employee stock options and restricted shares, or units, using the treasury stock method.

Fair Value

Assets and liabilities measured at fair value are categorized into a fair value hierarchy based on whether the inputs to valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our own assumptions about the assumptions market participants would use. The fair value hierarchy includes three levels of inputs that may be used to measure fair value as described below.

Level 1 – Quoted prices in active markets for identical assets or liabilities. Level 1 assets and liabilities include debt securities that are traded in an active exchange market.

Level 2 – Observable inputs other than Level 1 prices such as quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 assets and liabilities include debt securities with quoted prices that are traded less frequently than exchange-traded instruments as well as debt securities whose value is determined using a pricing model with inputs that are observable in the market or can be derived principally from or corroborated by observable market data.

Level 3 – Unobservable inputs that are supported by little or no market activity and are significant to the fair value of the assets or liabilities. Level 3 includes assets and liabilities whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques reflecting our own assumptions about the assumptions market participants would use as well as those requiring significant management judgment.

Fair value of actively traded debt securities are based on quoted market prices. Fair value of other debt securities are based on quoted market prices of identical or similar securities or based on observable inputs like interest rates generally using a market valuation approach, or, less frequently, an income valuation approach and are generally classified as Level 2. We obtain at least one quoted price for each security from a third party pricing service. These prices are generally derived from recently reported trades for identical or similar securities, including adjustments through the reporting date based upon observable market information. When quoted prices are not available, the third party pricing service may use quoted market prices of comparable securities or discounted cash flow analyses, incorporating inputs that are currently observable in the markets for similar securities. Inputs that are often used in the valuation methodologies include benchmark yields, reported trades, credit spreads, broker quotes, default rates, and prepayment speeds. We are responsible for the determination of fair value and as such we perform analysis on the prices received from the third party pricing service to determine whether the prices are reasonable estimates of fair value. Our analysis includes a review of monthly price fluctuations as well as a quarterly comparison of the prices received from the pricing service to prices reported by our third party investment advisor. In addition, on a quarterly basis we examine the underlying inputs and assumptions for a sample of individual securities across asset classes, credit rating levels, and various durations.

Fair value of privately held debt securities, as well as auction rate securities, are estimated using a variety of valuation methodologies, including both market and income approaches, where an observable quoted market does not exist and are generally classified as Level 3. For privately-held debt securities, such methodologies include reviewing the value ascribed to the most recent financing, comparing the security with securities of publicly-traded companies in similar lines of business, and reviewing the underlying financial performance including estimating discounted cash flows. Auction rate securities are debt instruments with interest rates that reset through periodic short-term auctions. From time to time, liquidity issues in the credit markets have led to failed auctions. Given the liquidity issues, fair value could not be estimated based on observable market prices, and as such, unobservable inputs were used. For auction rate securities, valuation methodologies include consideration of the quality of the sector and issuer, underlying collateral, underlying final maturity dates, and liquidity.

Recently Issued Accounting Pronouncements

There are no recently issued accounting standards that apply to us or that will have a material impact on our results of operations, financial condition, or cash flows.
