Cash and Cash Equivalents [Abstract]
Cash, Cash Equivalents, and Short-Term Investments	NOTE 6. CASH, CASH EQUIVALENTS, AND SHORT-TERM INVESTMENTS Cash and cash equivalents consist of cash on deposit with banks, money market funds, and all highly liquid investments with a remaining maturity of three months or less at the time of purchase. The Company considers all highly liquid investments with a remaining maturity at the time of purchase of more than three months but no longer than 12 months to be short-term investments. The Company classifies its short-term investments as available-for-sale securities and reports them at fair value with related unrealized gains and losses included as a component of comprehensive income. The amortized cost of debt securities in this category is adjusted for amortization of premiums and accretion of discounts to maturity, which is included in other income (expense), net, on the condensed consolidated statements of operations. Realized gains and losses and declines in value judged to be other-than-temporary, if any, on available-for-sale securities are included in other income (expense), net. The cost of securities sold is based on the specific identification method. Interest and dividends on securities classified as available-for-sale are included in other income (expense), net. For the three and nine months ended September 30, 2015, total realized gains and losses on sales of available-for-sale securities were not material. There were no realized gains or losses from sales of available-for-sale securities for the three and nine months ended September 30, 2014.

NOTE 6. CASH, CASH EQUIVALENTS, AND SHORT-TERM INVESTMENTS

Cash and cash equivalents consist of cash on deposit with banks, money market funds, and all highly liquid investments with a remaining maturity of three months or less at the time of purchase.

The Company considers all highly liquid investments with a remaining maturity at the time of purchase of more than three months but no longer than 12 months to be short-term investments. The Company classifies its short-term investments as available-for-sale securities and reports them at fair value with related unrealized gains and losses included as a component of comprehensive income. The amortized cost of debt securities in this category is adjusted for amortization of premiums and accretion of discounts to maturity, which is included in other income (expense), net, on the condensed consolidated statements of operations. Realized gains and losses and declines in value judged to be other-than-temporary, if any, on available-for-sale securities are included in other income (expense), net. The cost of securities sold is based on the specific identification method. Interest and dividends on securities classified as available-for-sale are included in other income (expense), net.

For the three and nine months ended September 30, 2015, total realized gains and losses on sales of available-for-sale securities were not material. There were no realized gains or losses from sales of available-for-sale securities for the three and nine months ended September 30, 2014.
