Note 4 - Fair Value of Financial Instruments | 3 Months Ended

Mar. 31, 2016
Fair Value Disclosures [Abstract] |
Fair Value of Financial Instruments | Fair Value of Financial Instruments Available for sale securities, trading securities and certain other assets are recorded at fair value. All changes in the fair value of trading securities and certain other assets are included in our condensed consolidated statements of operations. All changes in the fair value of available for sale securities are recorded in AOCI. There were no significant changes to our fair value methodologies during the three months ended March 31, 2016. In accordance with GAAP, we established a three-level valuation hierarchy for disclosure of fair value measurements based on the transparency of inputs to the valuation of an asset or liability as of the measurement date. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level I measurements) and the lowest priority to unobservable inputs (Level III measurements). The level in the fair value hierarchy within which the fair value measurement falls is determined based on the lowest level input that is significant to the measurement in its entirety. The three levels of the fair value hierarchy are defined below:
Level I | — Unadjusted quoted prices for identical assets or liabilities in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;
Level II | — Prices or valuations based on observable inputs other than quoted prices in active markets for identical assets and liabilities; and
Level III | — Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable. Level III inputs are used to measure fair value only to the extent that observable inputs are not available.
The level of market activity used to determine the fair value hierarchy is based on the availability of observable inputs market participants would use to price an asset or a liability, including market value price observations. We provide a qualitative description of the valuation techniques and inputs used for Level II recurring and non-recurring fair value measurements in our audited annual financial statements as of December 31, 2015. For a complete understanding of the valuation techniques and inputs used as of March 31, 2016, these unaudited condensed consolidated financial statements should be read in conjunction with the audited annual financial statements and notes thereto included in our 2015 Form 10-K. The following is a list of assets that are measured at fair value by hierarchy level as of March 31, 2016:
