101 Certain ef fects on diluted net income per common share may result in future periods as a result of the Company’ s (i) $355.0 million in 0.875% Convertible Notes and the Company’ s entry into note hedge and warrant agreements and (ii) the $429.5 million in Subordinated Convertible Notes. Refer to Note 9 - Long-T erm Debt for a description of the key terms of these transactions. Under ASC 260 - Earnings per Shar e and ASC 470 - Debt and because of the Company’ s obligation to settle the par value of the 0.875% Convertible Notes, 1.00% Senior Convertible Notes, and the Subordinated Convertible Notes in cash, the Company is not required to include any shares underlying the 0.875% Convertible Notes, 1.00% Senior Convertible Notes and Subordinated Convertible Notes in its weighted average shares outstanding — assuming dilution until the average stock price per share for the quarter exceeds the $50.36 , $83.93 , and $36.75 conversion price of the 0.875% Convertible Notes, 1.00% Senior Convertible Notes and the Subordinated Convertible Notes, respectively , and only to the extent of the additional shares that the Company may be required to issue in the event that the Company’ s conversion obligation exceeds the principal amount of the 0.875% Convertible Notes, the 1.00% Senior Convertible Notes and the Subordinated Convertible Notes. Regarding the 0.875% Convertible Notes, the average stock price threshold conditions had not been met as of December 31, 2012 . At any such time in the future that the threshold conditions are met, only the number of shares issuable under the “treasury” method of accounting for the share dilution would be included in the Company’ s earnings per share — assuming dilution calculation, which is based upon the amount by which the average stock price exceeds the conversion price. In addition, shares underlying the warrants will be included in the weighted average shares outstanding — assuming dilution when the average stock price per share for a quarter exceeds the $76.00 strike price of the warrants, and shares underlying the note hedges, will not be included in the weighted average shares outstanding — assuming dilution because the impact of the shares will always be anti-dilutive. The following table provides examples of how changes in the Company’ s stock price would require the inclusion of additional shares in the denominator of the weighted average shares outstanding — assuming dilution calculation for the 0.875% Convertible Notes. The table also reflects the impact on the number of shares that the Company would expect to issue upon concurrent settlement of the 0.875% Convertible Notes and the note hedges and warrants.

(2) Represents the number of incremental shares to be issued by the Company upon conversion of the 0.875% Convertible Notes, assuming concurrent settlement of the note hedges and warrants. Regarding the 1.00% Senior Convertible Notes, the average stock price threshold conditions had not been met as of December 31, 201 1 . The 1.00% Senior Convertible Notes had been repaid as of December 31, 2012 . At any such time in the future the threshold conditions are met, only the number of shares issuable under the “treasury” method of accounting for the share dilution would be included in the Company’ s earnings per share — assuming dilution calculation, which is based upon the amount by which the average stock price exceeds the conversion price. The following table provides examples of how changes in the Company’ s stock price would require the inclusion of additional shares in the denominator of the weighted average shares outstanding — assuming dilution calculation for the 1.00% Senior Convertible Notes.
