Business Combinations [Abstract]
Acquisitions	NOTE 3 – Acquisitions Rand & Associates On October 1, 2018, the Company completed the acquisition of Rand & Associates (“Rand”), an independent investment adviser that provides comprehensive wealth management and investment counsel services to individuals, families, and institutions. The acquisition was funded with cash from operations. The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805 (“ASC Topic 805”), “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $8.3 million of goodwill in the consolidated statement of financial condition, which has been allocated to our company’s Global Wealth Management segment. Identifiable intangible assets purchased by our company consisted of customer relationships with an acquisition-date fair value of $4.6 million. The allocation of the purchase price of Rand is preliminary and will be finalized upon completion of the analysis of the fair values of the net assets of Rand as of the acquisition date and the identified intangible assets. The final goodwill recorded on the consolidated statement of financial condition may differ from that reflected herein as a result of future measurement period adjustments and the recording of identified intangible assets. The goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of the Rand business and of the hired financial advisors and the conversion of the customer accounts to our platform. Goodwill is expected to be deductible for federal income tax purposes. We recognized a liability for estimated earn-out payments. These payments will be based on the performance of Rand over a five-year period. The liability for earn-out payments was $4.1 million at December 31, 2018. The contingent consideration accrual is included in accounts payable and accrued expenses in the consolidated statements of financial condition. Pro forma information is not presented, because the acquisition is not considered to be material, as defined by the SEC. The results of operations of Rand have been included in our results prospectively from the date of acquisition. Business Bancshares, Inc. On August 31, 2018, the Company completed the acquisition of Business Bancshares, Inc. (“BBI”) and its wholly owned subsidiary, The Business Bank of St. Louis, a full-service banking facility that operates from a single location. Upon the closing of the transaction, the Business Bank of St. Louis was renamed “Stifel Bank” and Business Bancshares, Inc. was renamed “Stifel Bancorp, Inc.” Stifel Bancorp, Inc. (“Stifel Bancorp”) is the holding company for Stifel Bank & Trust, and its wholly owned subsidiaries, and Stifel Bank. Under the terms of the merger agreement, each outstanding share of BBI common stock (except for shares of BBI common stock held by BBI as treasury stock) were converted into the right to receive 0.705 shares of our company’s common stock, with fractional shares settled with cash. We issued approximately 2.0 million shares for acquisition of BBI. We acquired approximately $507.8 million of loans, and $85.7 million of other assets (primarily cash and due from banks and investment securities). In addition, we assumed approximately $501.1 million of deposits and $21.9 million of other liabilities. Assets acquired and liabilities assumed were recorded at fair value. The fair values for loans were estimated using discounted cash flow analyses using interest rates currently being offered for loans with similar terms. This value was reduced by an estimate of probable losses and the credit risk associated with the loans. The fair values of deposits were estimated by discounting cash flows using interest rates currently being offered on deposits with similar maturities. The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805, “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $38.4 million of goodwill and intangibles in the consolidated statement of financial condition, which has been allocated to our company’s Global Wealth Management segment. Identifiable intangible assets purchased by our company consisted of core deposits with an acquisition date fair value of $8.6 million. The allocation of the purchase price of BBI is preliminary and will be finalized upon completion of the analysis of the fair values of the net assets of BBI as of the acquisition date and the identified intangible assets. The final goodwill recorded on the consolidated statement of financial condition may differ from that reflected herein as a result of future measurement period adjustments and the recording of identified intangible assets. The goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of the BBI business and its customer base.
