Subsequent Events [Abstract]
Subsequent Events	16. Subsequent Events On July 22, 2021, a company in which we were a preferred equity investor—Matterport, Inc.—completed a business combination with a public company. The carrying value of our investment, which was classified as a non-marketable equity investment, was approximately $8.7 million as of June 30, 2021. Our preferred shares were converted into common shares of the public company upon completion of the business combination. The common shares will be measured at fair value with unrealized gains and losses recorded to other income (expense), net. As of the date of the business combination, the unrealized gain on the investment was approximately $54 million. The impact of the investment on our results will vary as the share price fluctuates.

The entire disclosure for significant events or transactions that occurred after the balance sheet date through the date the financial statements were issued or the date the financial statements were available to be issued. 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.
