** | Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a). |
(1) | The original Form 3 erroneously reported that the Reporting Person indirectly owns 3,507 shares in a 401(k) plan. The Reporting Person does not hold any such shares, and this amendment is accordingly filed to delete references to those shares. |
(2) | Includes 144,244 restricted share units that vest as follows: 4,000 that vest on February 5, 2014; 3,000 that vest on December 7, 2013; an aggregate of 30,000 that vest ratably on each of November 7, 2013, 2014 and 2015; an aggregate of 75,000 that vest ratably on each of February 12, 2014, 2015 and 2016; and an aggregate of 32,244 that vest ratably on each of March 7, 2014, 2015 and 2016. |
(3) | The Reporting Person holds 32,244 performance share units. Each performance unit represents a contingent right to receive 0 to 2 shares. The conversion ratio ultimately applied to these performance units will be determined based on the absolute increase in the issuer's share price over the performance period (fiscal years 2013-2015). The units are scheduled to vest on January 1, 2016. |
