Cost method investments

In 2015 and 2014, the Company recorded $4.5 million and $66.6 million, respectively, of other-than-temporary impairment charges for certain cost method investments as a result of our assessment of the near-term prospects and financial condition of the investees. These charges are included in "Other income (expense), net" in the accompanying consolidated statement of operations.

The Company, through Match Group, has a 21% interest in the voting common stock of Zhenai Inc. ("Zhenai"), a leading provider of online dating and matchmaking services in China. However, given the significance of our interest relative to other shareholders, we do not have the ability to exercise significant influence over the operating and financial matters of Zhenai and this investment is accounted for as a cost method investment.

Equity method investments

In 2014, the Company recorded a $4.2 million other-than-temporary impairment charge on one of its investments following the sale of a majority of the investee's assets. These charges are included in "Equity in losses of unconsolidated affiliates" in the accompanying consolidated statement of operations.

Long-term marketable equity security

The cost basis of the Company's long-term marketable equity security at December 31, 2015 and 2014 is $5.0 million and $8.7 million, respectively, with a gross unrealized gain of $2.6 million and a gross unrealized loss of $1.2 million, respectively. The gross unrealized gain at December 31, 2015 and gross unrealized loss at December 31, 2014 are included in "Accumulated other comprehensive loss" in the accompanying consolidated balance sheet.
