We issued 18,458,700 shares of common stock in connection with the private placement. A total of 108,506,312 shares of common stock were issued in the IPO and concurrent private placement for gross proceeds of $2,381.0 million.

Also on August 8, 2018, The Dun & Bradstreet Corporation ("Dun & Bradstreet") entered into an Agreement and Plan of Merger (the ‘‘Merger Agreement’’) with Parent and Merger Sub. On February 8, 2019, pursuant to the terms of the Merger Agreement, Merger Sub merged with and into Dun & Bradstreet with Dun & Bradstreet continuing as the surviving corporation. The transaction is referred to as the ‘‘Take-Private Transaction. ’’See further discussion on Note 15.</span></div><div style="margin-top:9pt;text-indent:24.75pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">As a result of the Take-Private Transaction on February 8, 2019, the merger was accounted for in accordance with ASC 805, ‘‘Business Combinations’’ (‘‘ASC 805’’), and Dun & Bradstreet Holdings, Inc. was determined to be the accounting acquirer. The accompanying condensed consolidated financial statements and information are presented on a Successor and Predecessor basis. References to Predecessor refer to the results of operations, cash flows and financial position of The Dun & Bradstreet Corporation and its subsidiaries prior to the closing of the Take-Private Transaction. References to Successor refer to the consolidated financial position of Dun & Bradstreet Holdings, Inc. and its subsidiaries as of September 30, 2020 and December 31, 2019, and the results of operations and cash flows of Dun & Bradstreet Holdings, Inc. and its subsidiaries for the three and nine months ended September 30, 2020, the three months ended September 30, 2019 and the period from January 1, 2019 to September 30, 2019. During the period from January 1, 2019 to February 7, 2019, Dun & Bradstreet Holdings, Inc. had no significant operations and limited assets and had only incurred transaction related expenses prior to the Take-Private Transaction. The Successor period includes the consolidated results of operations, cash flows and financial position of Dun & Bradstreet and its subsidiaries on and after February 8, 2019. The Predecessor and Successor consolidated financial information presented herein is not comparable primarily due to the impacts of the Take-Private Transaction including the application of acquisition accounting in the Successor financial statements as of February 8, 2019, as further described in Note 15, of which the most significant impacts are (i) the increased amortization expense for intangible assets; (ii) additional interest expense associated with debt financing arrangements entered into in connection with the Take-Private Transaction; (iii) higher non-recurring transaction costs and the pension settlement charge attributable to the Take-Private Transaction; and (iv) a shorter Successor period for our International operations.</span></div><div style="margin-top:9pt;text-indent:24.75pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">All intercompany transactions and balances have been eliminated in consolidation.</span></div><div style="margin-top:9pt;text-indent:24.75pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Since the Take-Private Transaction, management has made changes to transform our business. As a result, during the fourth quarter of 2019, we changed the composition of our reportable segments, the classification of revenue by solution set and our measure of segment profit (from operating income to adjusted EBITDA (see Note 18 for further discussion of adjusted EBITDA) in the information that we provide to our chief operating decision makers ("CODMs") to better align with how they assess performance and allocate resources. Latin America Worldwide Network, which was previously included in the Americas reportable segment, is currently included in the International segment. Accordingly, prior period results have been recast to conform to the current presentation of segments, revenue by solution, and the measure of segment profit.
