Based on the Company's evaluation of such securities, it has determined that certain unrealized losses represented other-than-temporary impairments. This determination was based on several factors, including adverse changes in the market conditions and economic environments in which the entities operate. The Company recognized impairment charges of approximately $7.9 million and $30.6 million for the three and nine months ended September 30, 2015 , respectively, equal to the costs basis of such securities in excess of their fair values. The Company has determined that there was no indication of other-than-temporary impairments on its other investments with unrealized losses as of September 30, 2015 . This determination was based on several factors, including the length of time and extent to which fair value has been less than the cost basis, the financial condition and near-term prospects of the entity, and the Company's intent and ability to hold the corporate securities for a period of time sufficient to allow for any anticipated recovery in market value. The amortized cost and estimated fair value of available-for-sale debt securities and marketable securities with no contractual maturities at September 30, 2015 , by contractual maturity, were as follows: Cost Estimated Fair Value (in thousands) Debt securities that mature in more than three years $ 34,034 $ 29,844 Securities with no contractual maturities 139,077 141,989 Total $ 173,111 $ 171,833 Financial Instrument Obligations Financial instrument obligations consisted of the following: September 30, 2015 December 31, 2014 Initial Obligation Estimated Fair Initial Obligation Estimated Fair (in thousands) Corporate securities $ 675 $ 1,024 $ 666 $ 621 Market indices 18,685 19,067 18,685 20,451 Covered call options 113 80 7 4 Naked put options — — 109 235 Total $ 19,473 $ 20,171 $ 19,467 $ 21,311 For the three and nine months ended September 30, 2015 , the Company recognized gains on the financial instrument obligations totaling $1.3 million and $1.1 million , respectively, and for the three and nine months ended September 30, 2014 , the Company incurred losses on the financial instrument obligations totaling $0.1 million and $0.8 million , respectively, all of which are included as a component of "Other income (expense), net" in the Company's consolidated statements of operations. Equity-Method Investments In January 2013, the Company acquired a 40% membership interest in Again Faster LLC ("Again Faster"), a fitness equipment company. In response to adverse developments in its business, in 2015 Again Faster began seeking out additional investors or buyers for the business and is currently pursuing other strategic alternatives, including liquidation. Based on the current state of the business and the available strategic alternatives, the Company fully impaired its investment in Again Faster as of September 30, 2015 . In August 2013, the Company acquired approximately 44.7% of the common stock of iGo, Inc.

In May 2014, the Company increased its holdings of the common stock of API Technologies Corp. (“API”), a designer and manufacturer of high performance systems, subsystems, modules, and components, to 11,377,192 shares through the acquisition of 1,666,666 shares on the open market. Upon acquiring such shares the Company held approximately 20.6% of the total outstanding common stock of API. Effective as of that date the investment in API has been accounted for as an equity-method investment using the fair value option, with changes in fair value based on the market price of API's common stock recognized currently as income or loss from equity method investees. The Company elected the fair value option to account for its investment in API in order to more appropriately reflect the value of API in its financial statements. Prior to such time the investment in API was accounted for as an available-for-sale security, and upon the change in classification the Company recognized a loss of approximately $0.6 million that had previously been included as a component of "accumulated other comprehensive income".

("Aviat"), a global provider of microwave networking solutions. At the time of the appointment, the Company held 8,042,892 shares of Aviat, or approximately 12.9% of the total outstanding common stock. Effective as of the date of the appointment, the investment in Aviat has been accounted for as an equity-method investment as the Company’s voting interest and board representation provide it with significant influence over Aviat's operations. The Company elected the fair value option to account for its investment in Aviat, with changes in fair value based on the market price of Aviat's common stock recognized currently as income or loss from equity method investees, in order to more appropriately reflect the value of Aviat in its financial statements. Prior to such time the investment in Aviat was accounted for as an available-for-sale security, and upon the change in classification the Company recognized a loss of approximately $2.8 million that had previously been included as a component of "accumulated other comprehensive income".
