As part of the share repurchase programs, in February 2014, the Company entered into an accelerated share repurchase (“ASR”) contract with a commercial bank to purchase $140 million of the Company’s common stock. The Company paid $140 million to the bank, inclusive of fees, and received an initial delivery of approximately 2 million shares, which reduced the Company’s shares outstanding.
