Temporary Equity Disclosure [Abstract]
Class A Redeemable Convertible Preferred Stock	Class A Redeemable Convertible Preferred Stock On December 30, 2015, (“Original Issue Date”), the Company issued 14,666,667 shares of its Series A Preferred Stock as part of the consideration given to acquire all of the outstanding stock of Clarient Inc. The Series A Preferred Stock has a face value of $7.50 per share for a total liquidation value of $110.0 million. During the first year, the Series A Preferred Stock had a liquidation value of $100.0 million if the shares were redeemed prior to December 29, 2016. On December 22, 2016, the Company redeemed 8,066,667 shares of the Series A Preferred Stock for $55.0 million in cash. The redemption amount per share equaled $6.82 ($7.50 minus the liquidation discount of 9.09%). In December 2017, the Company issued 264,000 additional shares of Preferred Stock as a Paid-in-Kind (“PIK”) dividend, resulting in a balance of 6,864,000 shares of Series A Preferred Stock outstanding at December 31, 2017. On June 25, 2018, the Company redeemed the remaining outstanding Series A Preferred Stock for an aggregate redemption amount of $50.1 million, prior to consideration of any transaction related expenses. The shares were redeemed at $7.30 per share, representing the applicable 4.55% redemption discount on the original liquidation preference plus an additional $0.14 per share in respect of accrued and unpaid dividends for 2018. Following the redemption, no shares of Series A Preferred Stock remain outstanding. The $9.1 million gain was calculated as the carrying value of the shares of preferred stock before the redemption of $37.8 million plus the amount of the BCF originally recorded with the redeemed shares of $21.3 million, as compared to the total consideration being paid, in this case the $50.1 million. Issue Discount The Company recorded the Series A Preferred Stock at a fair value of approximately $73.2 million, or $4.99 per share, on the Original Issue Date. The difference between the fair value of $73.2 million and the liquidation value of $110 million represents a discount of $36.8 million from the initial face value representing the impact the rights and features of the instrument had on the value to the Company. After the partial redemption, the Series A Preferred stock had a fair value of approximately $32.9 million, or $4.99 per share. The difference between the fair value of $32.9 million and the liquidation value of $49.5 million represented a discount of approximately $16.6 million. Beneficial Conversion Features The fair value of the common stock into which the Series A Preferred Stock was convertible exceeded the allocated purchase price fair value of the Series A Preferred Stock at the Original Issue Date and after the partial redemption in December of 2016 by approximately $44.7 million and $20.1 million, respectively, resulting in a BCF. The Company recognized the BCF as non-cash, deemed dividends to the holder of Series A Preferred Stock over the first three years the Series A Preferred Stock was outstanding, as the date the stock first became convertible was three years from the Original Issue Date. In addition to the BCF recorded at the Original Issue Date, we recorded additional BCF discounts for PIK shares accrued for the quarter ended March 31, 2018 as dividends. Automatic Conversion Absent an early redemption, each share of Series A Preferred Stock issued and outstanding as of the tenth anniversary of the Original Issue Date would have automatically converted into fully paid and non-assessable shares of common stock.
