Subsequent Events [Abstract]
Subsequent Events	Subsequent Events We consider events or transactions that occur after the balance sheet date but prior to the issuance of the financial statements to provide additional evidence for certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated as required. Trusted Labs, Inc. On July 12, 2018, we entered into a stock purchase agreement with Trusted Labs, Inc. (“Trusted”), an on-demand child care provider offering service in the San Francisco Bay Area and New York City, pursuant to which we acquired the outstanding shares of Trusted for total potential consideration of $8.0 million, consisting of an up-front payment of $4.5 million, up to $2.2 million in retention payments, earn-out payments of up to $1.0 million in aggregate to be earned consecutively over three-quarters following the closing, and payments of $0.3 million to settle liabilities. Given that the acquisition closed on July 12, 2018, we determined it was impractical to provide all the disclosure required for a business combination pursuant to ASC 805, Business Combinations, and we will provide applicable disclosures required under ASC 805, Business Combinations in a future filing.
