Note 3 - Fair Value Measurements and Marketable Securities

We, in accordance with U.S. GAAP, define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). Effective January 1, 2008, we elected the fair value option for certain of our marketable securities purchased since such adoption. Management initially elected the fair value option for certain of our marketable securities because it views such investment securities as highly liquid and available to be drawn upon for working capital purposes making them similar to cash and cash equivalents. Accordingly, for such investments, we record net unrealized gain or loss in the other income - investment and interest caption in our consolidated statements of comprehensive income. We have not elected the fair value option for marketable securities acquired after December 31, 2009. Although these assets continue to be highly liquid and available, we do not believe these assets are representative of our operating activities. These assets are representative of our investing activities, and they will be available for future needs of the Company to support its current and projected growth.

Certain of our assets and liabilities are reported at fair value in the accompanying balance sheets. Such assets and liabilities include cash and cash equivalents, marketable securities, accounts and notes receivable, accounts payable, income taxes payable and other accrued expenses. The following tables provide fair value measurement information for our marketable securities and deferred compensation fund investment assets as of June 30, 2012 and December 31, 2011.

The fair value of the municipal bonds is measured using pricing service data from an external provider. The fair value of equity investments in the funded deferred compensation plan are valued (Level 1) based on quoted market prices. The money market fund in the funded deferred compensation plan is valued (Level 2) at the net asset value (“NAV”) of the shares held by the plan at the end of the period. As a practical expedient, fair value of our money market fund is valued at the NAV as determined by the custodian of the fund. The money market fund includes short-term United States dollar denominated money-market instruments. The money market fund can be redeemed at its NAV at its measurement date as there are no significant restrictions on the ability of participants to sell this investment.

For the three and six month periods ended June 30, 2012, the other income - investment and interest caption on our consolidated statements of comprehensive income includes unrealized losses from marketable securities of $26,000 and $82,000, respectively, for investments recorded under the fair value option.

For the three and six month periods ended June 30, 2011, the other income—investment and interest caption on our consolidated statements of income includes unrealized losses from marketable securities of $107,000 and $252,000, respectively, for investments recorded under the fair value option.
