Business Combinations [Abstract]
PENDING ACQUISITION OF AEROJET ROCKETDYNE	PENDING ACQUISITION OF AEROJET ROCKETDYNEOn December 20, 2020, we entered into an agreement to acquire Aerojet Rocketdyne Holdings, Inc. (“Aerojet Rocketdyne”) for $51.00 per share, which is net of a $5.00 per share special cash dividend Aerojet Rocketdyne paid to its stockholders on March 24, 2021. This represents a post-dividend equity value of approximately $4.6 billion, on a fully diluted as-converted basis, and a transaction value of approximately $4.4 billion after the assumption of Aerojet Rocketdyne’s projected net cash. We expect to finance the acquisition through a combination of cash on hand and new debt issuances. The transaction was approved by Aerojet Rocketdyne’s stockholders on March 9, 2021, which was a closing condition. The transaction is expected to close in the later part of 2021, subject to receipt of regulatory approval under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and satisfaction of other closing conditions specified in the acquisition agreement. Our financial results will not include Aerojet Rocketdyne’s results until the acquisition is closed.
