RECENT DEVELOPMENTS, INCLUDING MERGERS AND ACQUISITIONS | (2) RECENT DEVELOPMENTS, INCLUDING MERGERS AND ACQUISITIONS On January 19, 2012, Council Oak Investment Corporation, a wholly-owned subsidiary of BancFirst, completed the sale of one of its investments that resulted in a pretax gain of approximately $4.5 million. After related expenses and income taxes, the increase in net income approximated $2.6 million. On July 12, 2011, the Company completed the acquisition of FBC Financial Corporation and its subsidiary bank, 1st Bank Oklahoma with banking locations in Claremore, Verdigris, and Inola, Oklahoma. The Company paid a premium of $1.5 million above the equity capital of FBC Financial Corporation. At acquisition, 1st Bank Oklahoma had approximately $217 million in total assets, $116 million in loans, $178 million in deposits and $18 million in equity capital. 1st Bank Oklahoma operated as a subsidiary of BancFirst Corporation until it was merged into BancFirst on February 17, 2012. The acquisition did not have a material effect on the Company’s consolidated financial statements. In November 2009, the FDIC issued a rule that required insured depository institutions to prepay their estimated quarterly risk-based assessments for the fourth quarter of 2009 and for all of 2010, 2011 and 2012. Prepaid deposit insurance of approximately $9.7 million was included in other assets in the accompanying consolidated balance sheet for the year ended December 31, 2012. In June 2013, the Company received a refund of $9.6 million for overpayment of this assessment.
