We had certain available-for-sale securities in a gross unrealized loss position, substantially all of which had been in such position for less than 12 months. There were no impairments considered "other-than-temporary" as it is more likely than not we will hold the securities until maturity or a recovery of the cost basis. The following table shows the fair values and the gross unrealized losses of these available-for-sale securities aggregated by investment types (in thousands):
Strategic investment During the nine months ended September 30, 2015, we purchased a non-marketable equity investment in a privately-held company. This investment is accounted for under the cost method as we have less than a 20% ownership interest and we do not have the ability to exercise significant influence over the operations of the company. The carrying value of our investment was $10.0 million as of September 30, 2015, which is included in "Other assets" on the condensed consolidated balance sheets. We monitor this non-marketable equity investment for impairment and will make an appropriate reduction in carrying value if we determine that an impairment charge is required based primarily on the financial condition and near-term prospects of the privately-held company. |
