NOTE I – FAIR VALUE

Our financial instruments include cash and cash equivalents, accounts receivable, marketable securities, accounts payable, short-term and long-term debt and two interest rate swap agreements. The carrying amount of these instruments approximates fair value due to the immediate or short-term maturities or, with respect to our debt and related interest rate swaps, variable interest rates associated with these instruments. The interest rate swap agreements have been recorded at their fair value based on a valuation received from an independent third party. Marketable securities are carried at their fair value as determined by quoted market prices.

Effective June 1, 2008, we adopted an accounting policy regarding fair value. Under this policy, fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. This policy establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The policy describes three levels of inputs that may be used to measure fair value which are provided in the table below. The adoption of this policy had no impact on our financial statements other than the disclosures presented herein.

 

Level 1

    Quoted prices in active markets for identical assets or liabilities. Level 1 assets include bank time deposits, money market funds, mutual funds and U.S. Treasury securities that are traded in an active exchange market.

Level 2

   

Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices 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 Include US government securities and corporate bonds. When quoted market prices are unobservable, we obtain pricing information from an independent pricing vendor. The pricing vendor uses various pricing models for each asset class that are consistent with what other market participants would use. The inputs and assumptions to the model of the pricing vendor are derived from market observable sources including: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, benchmark securities, bids, offers, and other market-related data. Since many fixed income securities do not trade on a daily basis, the methodology of the pricing vendor uses available information as applicable such as benchmark curves, benchmarking of like securities, sector groupings, and matrix pricing. The pricing vendor considers all available market observable inputs in determining the evaluation for a security. Thus, certain securities may not be priced using quoted prices, but rather determined from market observable information. These investments are included in Level 2 and primarily comprise our portfolio of corporate and government fixed income securities. Additionally included in Level 2 are interest rate swap agreements which are valued using a mid-market valuation model.

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 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination

of fair value requires significant management judgment or estimation. This category currently only includes auction rate securities where independent pricing information was not able to be obtained. Our investments in auction-rate securities were classified as Level 3 as quoted prices were unavailable since these auction rate securities issued by New York state and local government authorities failed auction. Due to limited market information, we utilized a discounted cash flow ("DCF") model to derive an estimate of fair value for all periods presented. The assumptions used in preparing the DCF model included estimates with respect to the amount and timing of future interest and principal payments, forward projections of the interest rate benchmarks, the probability of full repayment of the principal considering the credit quality and guarantees in place, and the rate of return required by investors to own such securities given the current liquidity risk associated with auction-rate securities.

 

There were no significant transfers in and out of Level 1 and 2 measurements for the three months ended August 31, 2011. There were no changes in Level 3 fair value instruments for the three months ended August 31, 2011.

The following tables provide information by level for assets and liabilities that are measured at fair value on a recurring basis (in thousands):

We are exposed to market risk due to changes in interest rates. To reduce this risk, we periodically enter into certain derivative financial instruments to hedge the underlying economic exposure. We use derivative instruments as part of our interest rate risk management strategy. The derivative instruments used are floating-to-fixed rate interest rate swaps, which are subject to cash flow hedge accounting treatment. We recognized interest expense of $123,000 for the three months ended August 31, 2011 and interest expense of $191,000 for the three months ended August 31, 2010 on the cash flow hedge.

In accordance with authoritative guidance on Accounting for Derivatives and Hedging Activities, as amended, our 2002 interest rate swap agreement qualifies for hedge accounting under GAAP and the 2006 interest rate swap agreement does not. Both are presented in the consolidated financial statements at their fair value. Changes in the fair value of derivative financial instruments are either recognized periodically in income or in stockholders' equity as a component of accumulated other comprehensive income (loss) depending on whether the derivative financial instrument qualifies for hedge accounting and, if so, whether it qualifies as a fair value or cash flow hedge. Generally, the changes in the fair value of derivatives accounted for as fair value hedges are recorded in income along with the portions of the changes in the fair value of hedged items that relate to the hedged risks. Changes in the fair value of derivatives accounted for as cash flow hedges, to the extent they are effective as hedges, are recorded in accumulated other comprehensive income (loss).
