Pursuant to the Loan Agreement, AEC gave to ESW a security interest in all of AEC’s assets, and GlassBridge pledged to ESW all of GlassBridge’s AEC stock and 30% of GlassBridge’s SportBLX stock. The Loan Agreement provides that, upon AEC’s default, AEC may elect to cooperate with ESW to effect a prearranged reorganization of AEC in bankruptcy, pursuant to which ESW acquires from GlassBridge all equity in AEC and certain of its assets, most notably property and equipment consisting of quantitative trading software, as well as deferred tax assets resulting from net operating losses, which amount would be used to satisfy the claims of all valid creditors and certain administrative expenses associated with the bankruptcy case, with all residual funds to be paid to GlassBridge. On April 22, 2021, AEC filed a voluntary petition for relief under chapter 11 of the United States Bankruptcy Code in the Bankruptcy Court for the District of Delaware. AEC’s prepackaged chapter 11 plan of reorganization was confirmed at a hearing on June 9, 2021 and became effective on June 15, 2021 (the “Effective Date”). Upon the occurrence of the Effective Date, ESW paid $8.5 million in consideration, less $325,000 that ESW had previously funded in the form of a postpetition debtor-in-possession loan to AEC to fund the costs of administration associated with AEC’s bankruptcy case. Also on the Effective Date, 50% of the equity in reorganized AEC was issued to ESW, and the other 50% of the equity in reorganized AEC was issued to ESW’s affiliate, ESW Capital LLC. Finally, on the Effective Date, GlassBridge received a release of its guaranty obligations to ESW as well as a license to use AEC’s quantitative trading software in connection with the sports industry. The license is world-wide, non-exclusive, transferable, assignable, perpetual, irrevocable, fully-paid, royalty-free and sublicensable, subject to certain limitations and conditions. On May 20, 2021, the Company received notice from OTCMarkets that, because we had not yet filed Form 10-K for 2020, quotation of the Company’s shares would be moved from the OTCQB market to Pink at market open on May 21, 2021. Upon the filing of this Form 10-K and our Quarterly Report on Form 10-Q for the quarter ended March 31, 2021, the Company will seek to restore quotation of the Company’s shares to the OTCQB market.
