Each Restricted Stock Unit represents a contingent right to receive one share of Altera common stock at no cost. The Compensation Committee of Altera Corporation's Board of Directors previously approved a grant effective on March 2, 2009 of performance-based Restricted Stock Units such that 100% of the vesting would be contingent on the Company achieving net income from continuing operations as a percentage of net sales of 17% or greater for fiscal year 2009. After achievement of the performance metric, the RSUs are still subject to a service requirement such that they will vest 25% annually commencing July 31, 2010. Effective February 1, 2010 the Compensation Committee certified that the Company achieved the performance metric for fiscal year 2009. Twenty five percent (25%) of the Restricted Stock Unit granted on 1/30/2006 became vested on January 30, 2010 and shares were delivered to the reporting person on that date. George A. Papa 2010-02-02
