Deferred Costs, Capitalized, Prepaid, and Other Assets Disclosure [Abstract] |
Other Assets | Other Assets Cash and cash equivalents consist of cash on deposit with several domestic banks and money market funds. As of March 31, 2018, we have $96.5 million in investment grade corporate and municipal bonds with maturity dates ranging from 2017 through early 2020. We intend to hold these bonds to maturity and have classified them as such. We believe cost approximates fair value because of the relatively short duration of these investments. The fair values of these securities are considered Level II as they are based on inputs from quoted prices in markets that are not active or other observable market data. These investments are included in short-term investments and non-current investments and other assets. We have a $15.0 million investment in convertible preferred stock representing a 20% interest in Record Holdings Pty Limited, a privately held Australian company specializing in digitizing the spoken word in court and legal proceedings. The investment in convertible preferred stock is accounted under the cost method because we do not have the ability to exercise significant influence over the investee and the securities do not have readily determinable fair values. Our investment is carried at cost less any impairment write-downs. Annually, our cost method investments are assessed for impairment. We do not reassess the fair value of cost method investments if there are no identified events or changes in circumstances that may have a significant adverse effect on the fair value of the investments. This investment is included in non-current investments and other assets.
