Investments And Fair Value Measurements |
Investments And Fair Value Measurements | B. INVESTMENTS AND FAIR VALUE MEASUREMENTS Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (i.e., 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. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value which are the following: Level 1 – Quoted prices in active markets for identical assets or liabilities. Level 2 – Inputs other than Level 1 that are observable, either directly or indirectly, 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 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The following table represents the Company's fair value hierarchy for its financial assets (cash equivalents and investments) measured at fair value on a recurring basis as of July 31, 2011 and 2010:
|  | July 31, 2011 |  |  |  | July 31, 2010 |
|  | Cash and Cash Equivalents |  |  | Auction Rate Securities |  |  |  | Cash and Cash Equivalents |  |  | Auction Rate Securities and Put Rights |
Levels of Input |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Level 1 |  |  | $ 215,435 |  |  | $ – |  |  |  |  | $ 247,751 |  |  |  | $ – |
Level 2 |  |  | – |  |  | – |  |  |  |  | – |  |  |  | – |
Level 3 |  |  | – |  |  | 2,042 |  |  |  |  | – |  |  |  | 5,327 |
|  |  | $ 215,435 |  |  | $ 2,042 |  |  |  |  | $ 247,751 |  |  |  | $ 5,327 |
The Company's cash equivalents are comprised of money market funds traded in an active market with no restrictions. In addition to the above investments, the Company holds non-qualified retirement plan assets of $8,715 at July 31, 2011 ($7,499 at July 31, 2010). These assets, which are held for the benefit of certain employees of the Company, represent Level 1 investments primarily in mutual funds which are valued using observable market prices in active markets. They are included in other assets on the Consolidated Balance Sheets. Level 3 assets consist of bonds with an auction reset feature ("auction rate securities" or "ARS") whose underlying assets are primarily student loans which are substantially backed by the federal government. Auction rate securities are long-term floating rate bonds tied to short-term interest rates. After the initial issuance of the securities, the interest rate on the securities is reset periodically, at intervals established at the time of issuance based on market demand for a reset period. Auction rate securities are bought and sold in the marketplace through a competitive bidding process often referred to as a "Dutch auction." If there is insufficient interest in the securities at the time of an auction, the auction may not be completed and the rates may be reset to pre-determined "penalty" or "maximum" rates based on mathematical formulas in accordance with each security's prospectus. The following table provides a reconciliation of the beginning and ending balances for the assets measured at fair value using significant unobservable inputs (Level 3 financial assets):
|  | 2011 |  |  | 2010 |
Balances at beginning of year |  | $ | 5,327 |  |  | $ | 120,578 |
Net change in other comprehensive income |  |  | 415 |  |  |  | 599 |
Net loss included in earnings |  |  | – |  |  |  | – |
Purchases |  |  | – |  |  |  | – |
Sales/Maturities |  |  | (3,700) |  |  |  | (115,850) |
Balances at end of year |  | $ | 2,042 |  |  | $ | 5,327 |
Auction Rate Securities At July 31, 2011, we held $2,150 (par value) of long-term investments comprised of tax-exempt ARS, which are variable-rate debt securities and have a long-term maturity with the interest being reset through Dutch auctions that are typically held every 7, 28 or 35 days. The securities have historically traded at par and are callable at par at the option of the issuer. Interest is typically paid at the end of each auction period or semi-annually. At July 31, 2011, the majority of the ARS we held were AAA rated or equivalent, and none were below A rated or equivalent, with most collateralized by student loans substantially backed by the U.S. Federal government. Since February 12, 2008, most auctions have failed for these securities and there is no assurance that future auctions on the ARS in our investment portfolio will succeed and, as a result, our ability to liquidate our investment and fully recover the par value of our investment in the near term may be limited or not exist. An auction failure means that the parties wishing to sell securities could not. In November 2008, the Company elected to participate in a rights offering by UBS AG ("UBS"), a Swiss bank which is one of the Company's investment providers, that provided the Company with the right (the "Put Rights") to sell to UBS at par value ARS purchased from UBS at any time during a two-year sale period beginning June 30, 2010. We have sold $3,700 of ARS at par since August 1, 2010, and as of July 31, 2011 all our ARS held by UBS had been sold at par. The Put Rights were not transferable or marginable. By electing to participate in the rights offering, the Company granted UBS the right, exercisable at any time prior to June 30, 2010 or during the two-year sale period, to purchase or cause the sale of the Company's ARS (the "Call Right"). At July 31, 2011, there was insufficient observable ARS market information available to determine the fair value of our ARS investments. Therefore, management, assisted by Houlihan, Smith & Company, Inc., an independent consultant, determined an estimated fair value. In determining the estimate, consideration was given to credit quality, final stated maturities, estimates on the probability of the issue being called prior to final maturity, impact due to extended periods of maximum auction rates and broker quotes. Based on this analysis, we recognized a total temporary impairment of $108 ($67 total net of tax in other comprehensive income which is in the equity section of the balance sheet) related to our long-term ARS investments of $2,150 (par value). We have no reason to believe that any of the underlying issuers of our ARS are presently at risk of default. Through July 31, 2011, we have continued to receive interest payments on the ARS in accordance with their terms. We believe we will be able to liquidate our investments without significant loss primarily due to the government guarantee of the underlying securities; however, it could take until the final maturity of the underlying notes (up to 30 years) to realize our investments' par value. Based on the terms of the UBS Call Right, which was exercisable at any time after June 30, 2010, effective June 30, 2009 the ARS held by UBS were classified as short-term. The remaining ARS held by another institution remains classified as long-term at July 31, 2011. Although there is uncertainty with regard to the short-term liquidity of these securities, the Company continues to believe that the carrying amount represents the fair value of these marketable securities because of the overall quality of the underlying investments and the anticipated future market for such investments. In addition, the Company has the intent and ability to hold these securities until the earlier of: when the market for ARS stabilizes, the issuer refinances the underlying security, a buyer is found outside of the auction process at acceptable terms or the underlying securities have matured.
