Fair Value Measurements

(6) Fair Value Measurements

The Company holds certain assets that are required to be measured at fair value in accordance with United States GAAP. The Company determined fair value of these assets based on the following three levels of inputs:

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

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. Some of the Company's marketable securities primarily utilize broker quotes in a non-active market for valuation of these securities.

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, therefore requiring an entity to develop its own assumptions.

As of December 31, 2013, the Company held certain assets that are required to be measured at fair value on a recurring basis. Assets measured at fair value on a recurring basis are summarized below (in thousands):

(a): Auction rate securities included in "Other assets" in the Consolidated Balance Sheet

Based on market conditions, the Company uses a discounted cash flow valuation methodology for auction rate securities. Accordingly, for purposes of the foregoing consolidated financial statements, these securities were categorized as Level 3 securities. The Company's "Marketable Securities" classified as Level 2 primarily utilize broker quotes in a non-active market for valuation of these securities.

No significant transfers between Level 1, Level 2 and Level 3 occurred during the year ended December 31, 2013. The Company's policy regarding the recording of transfers between levels is to record any such transfers at the end of the reporting period.

The following table presents the Company's assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3) at December 31, 2013 (in thousands):
