The Company retained control in the Partnership based on the delegation of control provisions, as described in Note 2, Summary of Significant Accounting Policies and Basis of Presentation. As a result of the equity offering transactions described above, we recognized adjustments increasing the amount of the Class A shareholders’ capital balance by $27.0 million (2021: $52.4 million) and decreasing the carrying amount of noncontrolling interest by an equal amount to reflect the change in ownership interest. Class B Unit Repurchases On July 27, 2021, the Company, the Partnership and our Sponsors entered into a unit repurchase agreement pursuant to which the Partnership agreed to purchase from each Sponsor 15,625,000 Class B Units representing limited partner interests in the Partnership for an aggregate purchase price of $750.0 million. The purchase price per Class B Unit was $24.00, representing an approximate 4% discount to the 30-day volume weighted average trading price of Class A shares representing limited partner interests in the Company through July 27, 2021. Pursuant to the terms of the repurchase agreement, immediately following the purchase of the Class B Units from the Sponsors, the Partnership cancelled those units, and the Company cancelled, for no consideration, an equal number of Class B Shares representing limited partner interests in the Company held by the Company’s general partner. The repurchase transaction closed on August 10, 2021 and was funded through issuance by the Partnership of $750.0 million aggregate principal amount of senior unsecured notes (see Note 7, Debt and Interest Expense). On March 29, 2022, the Company, the Partnership and our Sponsors entered into a unit repurchase agreement pursuant to which the Partnership agreed to purchase from the Sponsors, subject to the secondary equity offering transaction described above, an aggregate number of Class B Units representing limited partner interests in the Partnership to be determined by dividing (a) $400.0 million by (b) the public offering price of the Class A Shares to be set in the secondary offering. On April 4, 2022, the repurchase transaction closed, and the Partnership purchased directly from the Sponsors 13,559,322 Class B Units at a purchase price per Class B Unit of $29.50, which is equal to the public offering price per Class A Share in the transaction described above. Pursuant to the terms of the repurchase agreement, immediately following the purchase of the Class B Units from the Sponsors, the Partnership cancelled those units, and the Company cancelled, for no consideration, an equal number of Class B Shares representing limited partner interests in the Company held by the Company’s general partner. The repurchase transaction was funded using borrowings under the Partnership’s revolving credit facility, which were subsequently repaid with proceeds from an issuance by the Partnership of $400.0 million senior unsecured notes (see Note 7, Debt and Interest Expense). The repurchase transactions were accounted for in accordance with ASC 810 whereby changes in a parent’s ownership interest while the parent retains its controlling financial interest in its subsidiary are accounted for as equity transactions. The carrying amounts of the noncontrolling interest were adjusted to reflect the changes in the ownership interest with the difference between the amounts of consideration paid and the amounts by which the noncontrolling interest were adjusted recognized as a reduction in equity attributable to Class A shareholders. We incurred approximately $1.5 million of costs directly attributable to the repurchase transaction (2021: $2.1 million) that were charged to equity. As a result of the equity offering transactions and the repurchase transactions described above, we also recognized an additional deferred tax asset of $86.4 million (2021: $89.0 million) related to the change in the temporary difference between carrying amount and tax basis of our investment in the Partnership. The effect of recognizing the additional deferred tax asset was included in Class A shareholders’ equity balance in the accompanying consolidated statement of changes in partners’ capital due to the transaction being characterized as a transaction among or with shareholders.
