Business Combination, Provisional Information, Initial Accounting Incomplete, Reasons | The estimated fair values of assets acquired and liabilities assumed are based on preliminary calculations and valuations using estimates and assumptions at the time of acquisition. The determination of the fair values of assets acquired and liabilities assumed, especially those related to identifiable intangible assets, is preliminary due to the complexity of combining multibillion dollar businesses. Accordingly, as the Company obtains additional information during the measurement period (not to exceed one year from the acquisition date), estimates and assumptions for the preliminary purchase consideration allocations may change materially. |  |
Business Combination, Reason for Business Combination | The Merger brought together two companies with highly compatible capabilities and characteristics. The combination of WESCO and Anixter created an enterprise with scale and should afford the Company the opportunity to digitize its business, and expand its services portfolio and supply chain offerings. |  |
Business Acquisition, Description of Acquired Entity | Anixter is a leading distributor of network and security solutions, electrical and electronic solutions, and utility power solutions with locations in over 300 cities across approximately 50 countries, and 2019 annual sales of more than $8 billion. |  |
Business Combination, Goodwill Recognized, Description | The resulting goodwill is primarily attributable to Anixter's workforce, significant cross-selling opportunities in additional geographies, enhanced scale, and other operational efficiencies.Since the initial measurement of the identified assets acquired and liabilities assumed, the Company has recognized adjustments to trade accounts receivable of $9.2 million, inventories of $8.5 million, operating lease assets of $18.0 million, total identifiable intangible assets of $5.4 million, other noncurrent assets of $15.5 million, accounts payable of $7.2 million, operating lease liabilities of $17.0 million, deferred income taxes of $30.9 million and other noncurrent liabilities of $40.0 million. Certain other measurement period adjustments were made to the identified assets acquired and liabilities assumed, none of which were significant, individually or in aggregate. The net impact of these adjustments was an increase to goodwill of $3.0 million. |  |
