Subsequent Events [Abstract]
Subsequent Event	Subsequent EventOn October 7, 2020, we entered into a definitive agreement to purchase the outstanding shares of Bisnode Business Information Group AB ("Bisnode"), for an estimated purchase price upon closing of approximately SEK 7.2 billion (approximately $818 million). Bisnode is a leading European data and analytics firm and long-standing member of the Dun & Bradstreet Worldwide Network. We expect the acquisition to position us to expand across Europe, increase our client base, and expand and enhance our Data Cloud. The transaction is expected to close in January 2021, subject to required regulatory approvals and customary closing conditions. Upon the close of the transaction, it is expected that 75% of the consideration for the equity value would be paid in cash and the remaining 25% would be paid in newly issued shares of common stock of the Company in a private placement. We will account for the transaction in accordance with ASC 805, "Business Combinations." In anticipation of the close of the transaction, we entered into a zero-cost foreign currency collar with the notional amount of SEK 4.8 billion to reduce our foreign currency exposure.
