The Company retained the current par value of $0.01 per share for all shares of common stock after the stock split, and accordingly, stockholders’ equity on the accompanying consolidated balance sheets and consolidated statements of changes in stockholders’ equity reflects the stock split by reclassifying from “Additional paid-in capital” to “Common stock” an amount equal to the par value of the additional shares arising from the split. The Company’s historical share and per share information has been retroactively adjusted to give effect to this stock split.

Contemporaneously with the stock split, on April 8, 2013, the Company’s Board of Directors approved an increase in the number of authorized shares of common stock to 1 billion shares.
