Fair Value Disclosures [Abstract]
Fair Value Option	7. Fair Value Option During the first quarter of FY 2018, the Company elected to account for its 5.75% Convertible Notes under the fair value option. The fair value carrying amount and the contractual principal outstanding balance of the 5.75% Convertible Notes accounted for under the fair value option as of December 31, 2019 is $47.3 million and $94.4 million, respectively. The change of $3.9 million and $81.0 million in the fair value of the 5.75% Convertible Notes accounted for under the fair value option are included in the Company’s consolidated statement of operations for FY 2019 and FY 2018 respectively, within Other Income. The primary reason for electing the fair value option is for simplification and cost-benefit considerations of accounting for the 5.75% Convertible Notes (the hybrid financial instrument) at fair value in its entirety versus bifurcation of the embedded derivatives. The 5.75% Convertible Notes contain bifurcatable embedded derivatives and do not require settlement by physical delivery of non-financial assets. The significant inputs to the valuation of the 5.75% Convertible Notes at fair value are Level 1 inputs, as they are based on the quoted prices of the notes in the active market.
