Temporary Equity Disclosure [Abstract]
Convertible Preferred Stock	Convertible Preferred StockOn October 18, 2021, we entered into a Subscription Agreement (the “Subscription Agreement”) with certain affiliates and related funds of White Hat Capital Partners LP and Magnetar Capital LLC (collectively, the “Investors”), relating to the issuance and sale of up to 125,000 shares of a new series of the Company's Series A Convertible Preferred Stock, par value $0.10 per share (the “Convertible Preferred Stock”), for an aggregate purchase price of up to $125,000,000, or $1,000 per share. On October 19, 2021 (the “Initial Closing Date”), pursuant to the terms of the Subscription Agreement, the Investors purchased an aggregate of 100,000 shares of Convertible Preferred Stock (the “Initial Issuance”) for an aggregate purchase price of $100,000,000. The Investors had a one-time option exercisable at any time on or prior to March 31, 2023 to purchase additional shares of Convertible Preferred Stock for an aggregate purchase price of $25,000,000. This purchase option, commonly referred to as a “Green Shoe” expired unexercised and together with the Initial Issuance, is collectively referred to as the “Issuance.” The adjusted conversion price for the shares issued in the Initial Issuance is $23.97, subject to certain adjustments set forth in the Certificate of Designations filed with the Secretary of State of the State of Delaware. The Convertible Preferred Stock ranks senior to the shares of our common stock, with respect to the payment of dividends and the distribution of assets upon a liquidation, dissolution or winding up of the Company. The Convertible Preferred Stock initially had a liquidation preference of $1,000 per share with each share entitled to a cumulative dividend (the “Dividend”) at the rate of 6.5% per annum, compounding quarterly, paid-in-kind or paid in cash, at our election. For any quarter in which we elect not to pay the Dividend in cash with respect to a share of Convertible Preferred Stock, such Dividend becomes part of the liquidation preference of such share. In addition, no dividend or other distribution on our common stock in excess of our $0.10 per share per quarter will be declared or paid on the common stock unless, at the time of such declaration and payment, an equivalent dividend or distribution is declared and paid on the Convertible Preferred Stock (the “Participating Dividend”), provided that in the case of any such dividend in the form of cash, in lieu of a cash payment, such Participating Dividend will become part of the liquidation preference of the shares of the Convertible Preferred Stock. Such Participating Dividend results in the Convertible Preferred Stock meeting the definition of a "participating security" for purposes of our earnings per share calculations. As of October 12, 2023, the Convertible Preferred Stock is convertible into shares of common stock at the option of the holders. At any time after October 19, 2024, we have the right to mandate the conversion of the Convertible Preferred Stock, subject to certain restrictions, based on the price of the common stock in the preceding thirty trading days. Holders of the Convertible Preferred Stock are entitled to vote with the holders of the common stock on an as-converted basis, as well as are entitled to a separate class vote with respect to, among other things, amendments to our organizational documents that have an adverse effect on the Convertible Preferred Stock, authorizations or issuances of securities of the Company, the payment of dividends other than dividends on common stock in the ordinary course consistent with past practice on a quarterly basis in an amount not to exceed our current dividend rate of $0.10 per share per quarter, related party transactions, repurchases or redemptions of securities of the Company (other than the repurchase of up to $25,000,000 of shares of common stock), dispositions of businesses or assets, the incurrence of certain indebtedness and certain amendments or extensions of our existing Credit Facility. Holders will have the right to require the Company to repurchase such holder's Convertible Preferred Stock on a date occurring either (a) on or after October 19, 2026 (the “Optional Repurchase Trigger Date”) at a price equal to the liquidation preference or (b) in connection with a conversion of Convertible Preferred Stock, pursuant to which the number of shares of common stock issuable upon such conversion would exceed 19.99% of the issued and outstanding shares of common stock as of October 18, 2021 (such excess shares, "Excess Conversion Shares"), at any time after the date that is 91 days after the maturity date of the Company's existing Credit Facility, at a price per share equal to the number of Excess Conversion Shares multiplied by the Last Reported Sales Price (as defined) of common stock on the applicable conversion date. In addition, each holder will have the right to cause the Company to repurchase its shares of Convertible Preferred Stock in connection with a Change of Control, at a price equal to the liquidation preference. We determined that our obligation to issue the Green Shoe at any time on or prior to March 31, 2023 met the definition of a freestanding financial instrument that should be accounted for as a liability. As such, we established an initial convertible preferred stock purchase option liability of $1,005,000 and reduced the proceeds from the Initial Issuance by such amount. The liability was remeasured to its estimated fair value each reporting period until such instrument expired. Changes in its estimated fair value were recognized as a non-cash charge or benefit and presented on the consolidated statement of operations. In accordance with ASC 480, "Distinguishing Liabilities from Equity," specifically ASC 480-10-S99-3A(2), SEC Staff Announcement: Classification and Measurement of Redeemable Securities, we have classified the Convertible Preferred Stock outside of permanent equity as temporary equity since the redemption of such shares is not solely within our control and we could be required by the holder to redeem the shares for cash or other assets, at their option. Upon the Initial Issuance, we recorded the Convertible Preferred Stock, net of issuance costs of $4,007,000 and net of the portion of such proceeds allocated to the convertible preferred stock purchase option liability described above, which resulted in an initial carrying value of the Convertible Preferred Stock less than its initial redemption value of $100,000,000. We have elected to adjust the carrying value of the Convertible Preferred Stock to its current redemption value of $112,211,000, which includes $11,607,000 of cumulative dividends paid in kind and $604,000 of accumulated and unpaid dividends. As such, a total adjustment of $7,007,000 to increase the carrying value of the Convertible Preferred Stock was recorded against retained earnings during fiscal 2023. On October 9, 2023, we received a non-binding term sheet from the Investors proposing (i) an exchange of their outstanding Series A Convertible Preferred Stock for a new series of convertible preferred stock on amended terms and (ii) purchase an additional amount of such new series of convertible preferred stock, on terms, conditions and assumptions described therein. No assurances can be given that a transaction will be consummated and the Investors reserve the right to withdraw the proposal at any time.
