Business Combination and Asset Acquisition [Abstract] |
Business Combinations | Business Combinations On November 15, 2021, the Company completed its acquisition of certain assets from The Allstate Corporation (“Allstate”). Through this business combination, the Company acquired approximately $581.6 million of loans, net of allowance for credit losses measured on the acquisition date. The loan portfolio was comprised of approximately 1,800 loans to Allstate agents nationally. In addition to acquiring the loans, the Company became the national preferred provider of loans to Allstate agents. In connection with the loan acquisition, a team of Allstate agency lending specialists joined the Company to augment and expand Wintrust’s existing insurance agency finance business. As the transaction was determined to be a business combination, the Company recorded goodwill of approximately $9.3 million on the purchase.
