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. As of June 2016, we have $34.4 million in investment grade corporate and municipal bonds with maturity dates ranging from 2016 through mid-2018. 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 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 fair value of this investment is based on valuations using Level III, unobservable inputs that are supported by little or no market value activity and that are significant to the fair value of the investment. This investment is included in non-current investments and other assets.
