(A) For the three months ended September 30, 2013, there were no remaining contingently issuable shares outstanding.

For the nine months ended September 30, 2013 and 2012, 2.3 million and 3.6 million as-if converted shares associated with the Company's convertible senior notes were excluded from the calculation as their effect would have been anti-dilutive.
