Fair Value of Financial Instruments

3. Fair Value of Financial Instruments

The carryingvalue of the Company’s cash and cash equivalents, accounts receivable and accounts payable approximate fair value because of their short-term nature. Investments are carried at fair market value and are classified as available-for-sale.  Investments consist of U.S. treasury notes with maturities up to approximately two years.  Fair value of investments is measured using Level 1 inputs (quoted prices for identical assets in active markets).

The following is a summary of available-for-sale securities:

	June 30,		December 31,
	2016		2015
Amortized cost	$	455,084	$	1,040,850
Gross unrealized gains (losses)		1,464		(2,712)
Fair market value	$	456,548	$	1,038,138

There were no realized gains (losses) from sales of available-for-sale securities during the three months ended June 30, 2016 and 2015.

The Company records realized gains and losses from sales of available-for-sale securities in interest and other income (expense) in the consolidated statement of operations.

The Company also maintains a rabbi trust to fund obligations under a deferred compensation plan. Amounts in the rabbi trust are invested in mutual funds, which are designated as trading securities and carried at fair value, and are included in other assets in the consolidated balance sheet.

The fair value of the investments in the rabbi trust was $17,111 and $18,331 as of June 30, 2016 and December 31, 2015, respectively.
