(2) | RECENT DEVELOPMENTS, INCLUDING MERGERS AND ACQUISITIONS
Effective June 1, 2017, the Company organized a new captive insurance company named BancFirst Risk and Insurance Company ("the Captive"). The Captive is a wholly-owned subsidiary of BancFirst Corporation and is regulated by the Oklahoma Insurance Department. It insures certain risks of the Company and has entered into reinsurance agreements with a risk-sharing pool. On July 31, 2017, the Company completed a two-for-one stock split of the Company’s outstanding shares of common stock. The stock was payable in the form of a dividend on or about July 31, 2017 to shareholders of record of the outstanding common stock as of the close of business record date of July 17, 2017. Stockholders received one additional share for each share held on that date. This represents the second stock split for the Company since going public. All share and per share amounts in these consolidated financial statements and related notes have been retroactively adjusted to reflect this stock split for all periods presented. On September 7, 2017, the Company announced it had entered into an agreement to acquire First Wagoner Corp. and its subsidiary bank, First Bank & Trust Company, with locations in Carney, Disney, Grove, Ketchum, Luther, Tulsa and Wagoner. First Bank & Trust Company has approximately $280 million in total assets, $258 million in loans, $244 million in deposits, and $36 million in equity capital. The transaction is expected to be completed in January 2018 upon regulatory approval. The bank will operate as First Bank & Trust Company until it is merged into BancFirst, which is expected to be during the first quarter of 2018. The acquisition will not have a material effect on the Company’s consolidated financial statements. On September 7, 2017, the Company announced it had entered into an agreement to acquire First Chandler Corp. and its subsidiary bank, First Bank of Chandler, with two locations in Chandler. First Bank of Chandler has approximately $90 million in total assets, $82 million in loans, $79 million in deposits, and $11 million in equity capital. The transaction is expected to be completed in January 2018 upon regulatory approval. The bank will operate as First Bank of Chandler until it is merged into BancFirst, which is expected to be during the second quarter of 2018. The acquisition will not have a material effect on the Company’s consolidated financial statements.
