On February 14, 2014, the Company's Board of Directors authorized a two-for-one split of the Company's common stock. The two-for-one common stock split will be accomplished by means of a stock dividend, to be distributed March 18, 2014 to stockholders of record as of February 28, 2014. The common stock split will require retroactive revision of all historical per share data beginning in the first quarter ending March 31, 2014. All references to the number of shares outstanding and per share data in these Consolidated Financial Statements are presented on a pre-split basis. Unaudited pro forma basic and diluted earnings per share, after giving retroactive effect to the stock split, are as follows:
