Deferred Costs Capitalized Prepaid And Other Assets Disclosure [Abstract]
Other Assets	(3) Other Assets Cash and cash equivalents consist of cash on deposit with several domestic banks and money market funds. In June 2015, we invested $6.4 million in investment grade corporate and municipal bonds with maturity dates ranging from 2015 through mid-2017. 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 value 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 other current assets and other non-current assets. On January 30, 2015, we made a $15.0 million investment in convertible preferred stock representing a 20% interest in Record Holdings Pty Limited (“Record Holdings”), a privately held Australian company specializing in digitizing the spoken word in court and legal settings. We do not believe we have the ability to significantly influence the day-to-day activities of Record Holdings and are accounting for this investment under the cost method.
