(3) FAIR VALUE MEASUREMENTS

The three-tier fair value hierarchy utilized prioritizes the inputs used in measuring fair value as follows: Level 1) observable inputs such as quoted prices in active markets; Level 2) inputs other than the quoted prices in active markets that are observable either directly or indirectly; and Level 3) unobservable inputs in which there is little or no market data, which require us to develop our own assumptions. The hierarchy requires us to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. On a recurring basis, we measure our available-for-sale securities at fair value. We used quoted prices in active markets (Level l) to measure the fair value of our cash equivalents on our Condensed Balance Sheets as of September 30, 2012 and December 31, 2011. Cash equivalents consist of highly rated money market funds with maturities of ninety days or less. Due to the high ratings and short-term nature of these funds, we consider the inputs used to value all cash equivalents as Level 1 inputs.
