Stock Plans	Stock Plans: Under the Philip Morris International Inc. 2008 Performance Incentive Plan (the “Plan”), PMI may grant to certain eligible employees stock options, stock appreciation rights, restricted stock, restricted stock units, deferred stock and deferred stock units and other stock-based awards based on PMI’s common stock, as well as performance-based incentive awards. Up to 70 million shares of PMI’s common stock may be issued under the Plan. At March 31, 2012, shares available for grant under the Plan were 26,074,253. PMI also adopted the Philip Morris International Inc. 2008 Stock Compensation Plan for Non-Employee Directors (the “Non-Employee Directors Plan”). A non-employee director is defined as each member of the PMI Board of Directors who is not a full-time employee of PMI or of any corporation in which PMI owns, directly or indirectly, stock possessing at least 50% of the total combined voting power of all classes of stock entitled to vote in the election of directors in such corporation. Up to 1 million shares of PMI common stock may be awarded under the Non-Employee Directors Plan. As of March 31, 2012, shares available for grant under the plan were 819,195. During the three months ended March 31, 2012, PMI granted 3.2 million shares of restricted and deferred stock awards to eligible employees at a weighted-average grant date fair value of $79.42 per share. During the three months ended March 31, 2011, PMI granted 3.8 million shares of restricted and deferred stock awards to eligible employees at a weighted average grant date fair value of $59.39 per share. PMI recorded compensation expense for restricted stock and deferred stock awards of $77 million and $38 million during the three months ended March 31, 2012 and 2011, respectively. Compensation expense for the three months ended March 31, 2012, includes approximately $27 million of accelerated expense primarily associated with employees approaching or reaching certain age milestones that accelerate the vesting. As of March 31, 2012, PMI had $392 million of total unrecognized compensation cost related to non-vested restricted and deferred stock awards. The cost is recognized over the original restriction period of the awards, which is typically three or more years after the date of the award, subject to earlier vesting on death or disability or normal retirement, or separation from employment by mutual agreement after reaching age 58. During the three months ended March 31, 2012, 3.6 million shares of PMI restricted stock and deferred stock awards vested. The grant date fair value of all the vested shares was approximately $141 million. The total fair value of restricted stock and deferred stock awards that vested during the three months ended March 31, 2012 was approximately $287 million.
