Note 19.

Fair Value Measurements

FASB ASC 820, "Fair Value Measurements and Disclosures," defines fair value, establishes a framework for measuring fair value in accordance with accounting principles generally accepted in the United States, and expands disclosures about fair value measurements.   The Company applies the provisions of ASC 820 to all its assets and liabilities that are being measured and reported on a fair value basis.

ASC 820 discusses valuation techniques, such as the market approach (comparable market prices), the income approach (present value of future income or cash flow) and the cost approach (cost to replace the service capacity of an asset or replacement cost).  ASC 820 enables readers of financial statements to assess the inputs used to develop those measurements by establishing a hierarchy, which prioritizes those inputs used, for ranking the quality and reliability of the information used to determine fair values.  The standard requires that each asset and liability carried at fair value be classified into one of the following categories:

Level 1: Quoted market prices in active markets for identical assets or liabilities.

Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data.

Level 3: Unobservable inputs that are not corroborated by market data.

The Company has an established process for determining fair value for its financial assets and liabilities, principally cash and cash equivalents and IDSI acquisition notes.  Fair value is based on quoted market prices, where available.  If quoted market prices are not available, fair value is based on assumptions that use as inputs market-based parameters.  The following sections describe the valuation methodologies used by the Company to measure different financial instruments at fair value, including an indication of the level in the fair value hierarchy in which each instrument is generally classified.  Where appropriate the description includes details of the key inputs to the valuations and any significant assumptions.

Cash equivalents.  Included within "Cash and cash equivalents" are principally investments in tax-free and taxable money market funds with municipal bond issuances as the underlying securities as well as government agency obligations and corporate bonds, all of which maintain AAA credit ratings.  Also included within cash equivalents were our investments in non-domestic bank certificates of deposit.  The Company uses quoted market prices to determine the fair value of these investments and they are classified in Level 1 of the fair value hierarchy.  The carrying amounts approximate fair value because of the short maturity of the instruments.

IDSI acquisition notes.  The Company issued non-interest bearing notes associated with its acquisition of IDSI.  The Company determined the fair value of these notes by computing the present value of the note payments using an interest rate formula applicable to the Company's long-term debt.  The short-term note is included within "Current maturities of other long-term debt", the long-term note was included within "Other long-term debt" and are classified in Level 2 of the fair value hierarchy.

The following assets and liabilities of the Company were measured at fair value on a recurring basis subject to the disclosure requirements of ASC Topic 820 at December 31, 2011 and December 31, 2010:
