(a) | In connection with our acquisition of Advanced Disposal, we and Advanced Disposal entered into an agreement that provided for GFL Environmental to acquire a combination of assets from us and Advanced Disposal to address divestitures required by the U.S. Department of Justice. Upon acquisition these assets met the criteria for reporting discontinued operations and were classified as held for sale and included within the “Assets held for sale” and “Liabilities held for sale” line items in the above final allocation of purchase price. Immediately following the
| acquisition, the divestiture transactions were consummated and the Company subsequently received cash proceeds from the sale of $856 million.
​
(b) | At the time of acquisition, Advanced Disposal had outstanding $425 million of 5.625% senior notes due November 2024, the fair value of which was $438 million. In November 2020, we redeemed the notes pursuant to an optional redemption feature.
