In 2013, in connection with the Company’s review of its equity method investments for other-than-temporary impairment, the Company determined that its equity investment in a privately-held company had experienced an other-than-temporary decline in value, due to recurring losses from operations, significant personnel reductions, and a change in the underlying business model. Accordingly, the Company wrote down the $3.7 million carrying value of the investment to zero, resulting in a loss.

The gain on third party bankruptcy settlement related to amounts received in connection with ongoing distributions from the Lehman Brothers estate, of which the Company is a creditor.
