Marketable Securities

Note 7.    Marketable Securities

As of December 31, 2012, the marketable securities were recorded at amortized cost which approximates fair market value which was based on Level 1 inputs. All investments mature in one year or less.

The Company would recognize an impairment loss when the decline in the estimated fair value of a marketable security below the amortized cost is determined to be other-than-temporary. The Company considers various factors in determining whether to recognize an impairment charge, including the duration of time and the severity to which the fair value has been less than the amortized cost, any adverse changes in the issuer’s financial conditions and the Company’s intent to sell or whether it is more likely than not that it would be required to sell the marketable security before its anticipated recovery. Investments with unrealized losses have been in an unrealized loss position for less than a year.

At December 31, 2012, the gross unrealized losses of $8 was primarily due to changes in interest rates and not credit quality of the issuer.
