Temporary Equity Disclosure [Abstract]
Convertible Preferred Stock	Convertible Preferred Stock On 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 our Series A Convertible Preferred Stock, par value $0.10 per share (the “Series A Convertible Preferred Stock”), for an aggregate purchase price of up to $125,000,000, or $1,000 per share. On October 19, 2021, pursuant to the terms of the Subscription Agreement, the Investors purchased an aggregate of 100,000 shares of Series A Convertible Preferred Stock for an aggregate purchase price of $100,000,000. White Hat Capital Partners LP is affiliated with Mark Quinlan, who serves as Chairman of our Board of Directors. On December 13, 2023, we and the Investors agreed to change certain terms of the Series A Convertible Preferred Stock, effected through an Exchange Agreement (the “Exchange Agreement”), pursuant to which the Investors exchanged (the “Series A Exchange”) all 100,000 shares of Series A Convertible Preferred Stock outstanding for 100,000 shares of our newly issued Series A-1 Convertible Preferred Stock, par value $0.10 per share (the “Series A-1 Convertible Preferred Stock”), with an initial liquidation preference of $1,134.20 per share. As a result of the Series A Exchange, no shares of Series A Convertible Preferred Stock remain outstanding. On January 22, 2024, we entered into a Subscription and Exchange Agreement (the “Subscription and Exchange Agreement”) with the Investors, relating to: (i) the issuance and sale of 45,000 shares of Series B Convertible Preferred Stock, par value $0.10 per share (the “Series B Convertible Preferred Stock”), for an aggregate purchase price of $45,000,000, or $1,000 per share (the “Primary Issuance”), (ii) the exchange of 100,000 shares of our Series A-1 Convertible Preferred Stock for 115,721.22 shares of Series B Convertible Preferred Stock (the “Series B Exchange”) and (iii) the issuance to the Investors of 5,400 shares of Series B Convertible Preferred Stock in lieu of cash for certain expense reimbursements (the “Additional Issuance” and, together with the Primary Issuance and the Series B Exchange, the “Series B Issuance”). As a result of the Series B Exchange, no shares of Series A-1 Convertible Preferred Stock remain outstanding. We received $43,200,000 of cash proceeds from the Primary Issuance, net of $1,800,000 for certain expense reimbursements. The Series B 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 Series B Convertible Preferred Stock has an initial liquidation preference of $1,000 per share with each share entitled to a cumulative dividend (the “Dividend”) at the rate of 9.00% per annum, compounding quarterly, paid-in-kind, or 7.75% per annum, compounding quarterly, paid in cash, at our election, or 6.50% per annum, in respect of any shares of Series B Convertible Preferred Stock that remain outstanding following the redemption of at least fifty percent (50%) of the Series B Preferred Stock pursuant to the exercise of an asset sale put right and/or an asset sale call right as described below. For any quarter in which we elect not to pay the Dividend in cash, such Dividend becomes part of the liquidation preference of the Series B Convertible Preferred Stock. In addition, no dividend or other distribution on our common stock will be declared or paid on our common stock unless, at the time of such declaration and payment, an equivalent dividend or distribution is declared and paid on the Series B 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 Series B Convertible Preferred Stock. Such Participating Dividend results in the Series B Convertible Preferred Stock meeting the definition of a "participating security" for purposes of our earnings per share calculations. The shares of Series B Convertible Preferred Stock are convertible into shares of common stock at the option of the holder thereof at any time. At any time after July 22, 2027, we have the right to mandate conversion of the Series B Convertible Preferred Stock, subject to certain restrictions based on the price of our common stock in the preceding thirty (30) trading days. The conversion price for the Series B Convertible Preferred Stock is $7.99, subject to certain adjustments set forth in the certificate of designations governing the Series B Convertible Preferred Stock (the "Series B Certificate of Designations"). Holders of the Series B Convertible Preferred Stock are entitled to vote with the holders of our common stock on an as-converted basis, and 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 Series B Convertible Preferred Stock, authorizations or issuances of securities of the Company (other than the issuance of up $50,000,000 of shares of common stock), the payment of dividends, related party transactions, repurchases or redemptions of securities of the Company, dispositions of businesses or assets involving consideration having a fair value in excess of $75,000,000, the incurrence of certain indebtedness and certain amendments or extensions of our Credit Facility on terms and conditions that, taken as a whole, (A) are materially different from the existing Credit Facility or (B) adversely affect our ability to perform our obligations in connection with an optional repurchase of the Series B Convertible Preferred Stock, in each case, subject to the exceptions and qualifications set forth in the Series B Certificate of Designations. Holders have the right to require us to repurchase their Series B Convertible Preferred Stock (at 1.0x the liquidation preference, plus accrued and unpaid dividends) on a date occurring either: (a) on or after October 31, 2028 or (b) upon the consummation of an asset sale meeting certain criteria. We have the right to repurchase all, or less than all, of the Series B Convertible Preferred Stock upon the consummation of an asset sale meeting the same criteria, other than an asset sale that would result in a change of control. In addition, each holder will have the right to cause us to repurchase its Series B Convertible Preferred Stock in connection with a change of control at 1.5x (or 1.0x in the case of Series B Convertible Preferred Stock issued in the Additional Issuance) the liquidation preference, plus accrued and unpaid dividends. Any repurchase described above would be subject to the terms set forth in the Series B Certificate of Designations. Upon a repurchase of the Series B Convertible Preferred Stock occurring as a result of an asset sale described above, we will issue each respective holder a warrant (a “Warrant”). A Warrant will represent the right to acquire our common stock, as further described in the Subscription and Exchange Agreement, for a term of five years and six months from the issuance of such Warrant, at an initial exercise price equal to the conversion price on the date of issuance of such Warrant, subject to certain adjustments. We determined that our obligation to issue a Warrant met the definition of a freestanding financial instrument that should be accounted for as a liability. We established an initial Warrant liability of $6,440,000, which was included in the consideration given to the Investors for purposes of determining the loss on extinguishment of the Series A-1 Convertible Preferred Stock as of January 31, 2024. The Warrant liability is classified in "Other Liabilities" on the Condensed Consolidated Balance Sheets and is remeasured to its estimated fair value each reporting period, using Level 3 fair value inputs, until the Warrant is exercised or expires. Changes in the estimated fair value of the Warrant will be recognized in our Condensed Consolidated Statement of Operations as a non-cash expense or benefit. As of April 30, 2024, the Warrant liability was remeasured, resulting in a $6,439,000 reduction to its estimated fair value. We accounted for the Series B Issuance and cancellation of Series A-1 Convertible Preferred Stock as an extinguishment based on a qualitative assessment of the terms of the preferred shares exchanged. We recognized a $13,640,000 loss on extinguishment, representing the aggregate value of the Warrant, the Additional Issuance and certain expense reimbursements. As the Series A-1 Convertible Preferred Stock was classified as temporary equity, the loss on extinguishment was accounted for as a dividend to the holders and charged against retained earnings, and included in net loss attributable to common shareholders. 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 classified the Series B 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 Series B Issuance, the initial redemption value (and estimated fair value) of the Series B Convertible Preferred Stock was $166,121,000, which was recorded at an initial carrying value of $161,848,000, net of initial issuance costs of $4,273,000. We have elected to adjust the carrying value of the Series B Convertible Preferred Stock to its current redemption value of $170,254,000, which includes $2,866,000 of cumulative dividends paid in kind and $1,267,000 of accumulated and unpaid dividends. During the nine months ended April 30, 2024, the adjustments charged against retained earnings to increase the carrying value of outstanding convertible preferred stock to their respective redemption values totaled $11,992,000, of which $8,482,000 related to the Series B Convertible Preferred Stock and $3,510,000 related to the Series A and A-1 Convertible Preferred Stock (while outstanding). Subsequent Event In connection with entering into the New Credit Facility discussed in Note (10) - "Credit Facility," on June 17, 2024, we and the Investors agreed to change certain terms of the Series B Convertible Preferred Stock. The changes altered the preferred holders’ existing consent rights and existing put rights alongside payments upon a change of control following specified asset sales, in each case consistent with the New Credit Facility. To effect these changes, we and the Investors entered into a Subscription and Exchange Agreement (the “Series B-1 Exchange”), pursuant to which the Investors: (i) exchanged, in a transaction exempt from registration under the Securities Act of 1933, all of the 166,121.22 shares of Series B Convertible Preferred Stock outstanding for 166,121.22 shares of our newly issued Series B-1 Convertible Preferred Stock, par value $0.10 per share, with an initial liquidation preference of $1,036.58 per share, and (ii) received 5,705.83 additional shares of Series B-1 Convertible Preferred Stock. Also, on June 17, 2024, we and the Investors entered into a Voting Agreement and Registration Rights Agreement and filed a Series B-1 Certificate of Designations with the Secretary of State of Delaware, complete copies of which are documented and filed with the SEC. Except for the changes described above, the powers, preferences and rights of the Series B-1 Convertible Preferred Stock are substantially the same as those of the Series B Convertible Preferred Stock, including, without limitation, that the shares of Series B-1 Convertible Preferred Stock are convertible into shares of common stock at a conversion price of $7.99 per share (the same as the current conversion price of the Series B Convertible Preferred Stock, and subject to the same adjustments). We did not receive any cash proceeds from the Series B-1 Exchange.
