5. Cash, Cash Equivalents and Investments

Cash and cash equivalents consist of highly liquid investments with maturities of three months or less at date of purchase. Cash equivalents are carried at cost, which approximates their fair market value. Cash and cash equivalents consisted of the following:

	As of December 31,
	2013		2012
Cash	$	13,805	$	15,064
Money market funds		1,607		33,345
Total cash and cash equivalents	$	15,412	$	48,409

The Company’s short and long-term investments are accounted for as available for sale securities. These investments are recorded at fair value with the related unrealized gains and losses included in accumulated other comprehensive income (loss), a component of stockholders’ equity, net of tax. The unrealized gain, net of taxes, was $10, $14 and $12 as of December 31, 2013, 2012 and 2011, respectively. Realized gains and losses on the sale of these investments are determined using the specific identification method. There were realized gains of approximately $23 in 2013; there were no realized gains or losses in 2012 or 2011.

Short and long-term investments consisted of the following:

The Company had two debt securities in an unrealized loss position at December 31, 2013. Both of these securities have been in such a position for no more than 20 months. The unrealized loss on those securities was approximately $1 and the fair value was $1.8 million. As of December 31, 2013, the Company does not consider these investments to be other-than-temporarily impaired.

Municipal and government agency bonds have contractual maturity dates that range from June 2014 to December 2015. All income generated from these investments is recorded as interest income.
