Subsequent Events [Abstract]
Subsequent Event	24)Subsequent Event (amounts not in millions) On February 4, 2021, we made a proposal to acquire in a cash and stock transaction Coherent, Inc. (“Coherent”), which had previously announced that it had entered into a definitive agreement with Lumentum Holdings, Inc. (“Lumentum”) pursuant to which Lumentum would acquire Coherent. Under the terms of our proposal to Coherent, if accepted by Coherent, Coherent shareholders would receive $115 cash and .7473 of a share of our common stock per share of Coherent common stock. We would expect to fund the potential transaction with cash on hand and debt financing. The execution of a definitive merger agreement between Coherent and us would be subject to approval of each party’s board of directors and completion of the transaction would be subject to customary closing conditions, including receipt of required regulatory approvals and approval of our and Coherent’s respective stockholders. Completion of the transaction would not be subject to any financing condition. On February 12, 2021, II-VI Incorporated (“II-VI”) submitted a separate proposal to acquire Coherent. While Coherent has publicly announced that both our proposal and that of II-VI could lead to a transaction that is superior to its pending transaction with Lumentum, it has not yet determined that either proposal is in fact superior. No assurances can be made that Coherent will accept our proposal.
