Equity	Equity In October 2016, the board of directors authorized a share repurchase program that allows Federated to buy back up to 4 million shares of Federated Class B common stock with no stated expiration date. No other programs existed as of September 30, 2017. The program authorizes executive management to determine the timing and the amount of shares for each purchase. The repurchased stock is to be held in treasury for employee share-based compensation plans, potential acquisitions and other corporate activities, unless Federated's board of directors subsequently determines to retire the repurchased stock and restore the shares to authorized but unissued status (rather than holding the shares in treasury). During the first nine months of 2017, Federated repurchased 1.6 million shares of Class B common stock for $42.3 million, the majority of which were repurchased in the open market. The remaining repurchased shares represent restricted stock forfeited by employees and are not counted against the board-approved share repurchase program. At September 30, 2017, 2.3 million shares remain available to be purchased under Federated's buyback program.
