Subsequent Events [Abstract]
Subsequent Events	SUBSEQUENT EVENT During the second quarter of 2022, we entered into two arrangements to license intellectual property. Under one arrangement we paid $45.0 million and expect to issue subsequent milestone payments during 2022 of $10.0 million . Under the second arrangement, we paid $30.0 million for an equity investment and license rights, with expected subsequent milestone payments of $20.0 million. We estimate approximately $80.0 million in the aggregate will be charged to research and development expense for these license rights during the second quarter.

Examples include: the sale of a capital stock issue, purchase of a business, settlement of litigation, catastrophic loss, significant foreign exchange rate changes, loans to insiders or affiliates, and transactions not in the ordinary course of business.
