[1] Gain on sale of subsidiary for the three months ended March 31, 2021 and nine months ended March 31, 2022 and 2021 was due to the sale of the Blow-Fill-Seal Business

[2] The additions to goodwill arise from the Bettera (Softgel and Oral Technologies) and RheinCell and Delphi (Biologics) acquisitions. For further details, see Note 3, Business Combinations and Divestitures.

[3] The note receivable, which provides for interest at a rate of 5.0% paid in kind, had an estimated fair value of $47 million, which is the $50 million aggregate principal amount less a $3 million discount determined using a discounted cash flow model with the market interest rate as a significant input.

[4] The Company determined that the estimated fair value of the contingent consideration from the sale of the Blow-Fill-Seal Business at March 31, 2022 is zero, and therefore, no contingent consideration was recorded as a result of the divestiture of the Blow-Fill-Seal Business. If any contingent consideration is subsequently received, it will be recorded in the period in which it is received. The Company has elected an accounting policy to recognize increases in the carrying amount of the contingent consideration asset using the gain contingency guidance in ASC 450, Contingencies.

[5] Other includes $8 million of transaction expenses, a working capital adjustment of $6 million, and a $2 million assumption of liabilities to create cumulative net cash proceeds of $284 million.
