Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]

We recognize the fair value of stock-based compensation as expense over the requisite service period of the individual grantees, which generally equals the vesting period. We provide newly issued shares of our common stock and treasury stock to satisfy the issuance of PA, SVA, and RSU shares. We classify tax benefits resulting from tax deductions in excess of the compensation cost recognized for stock-based compensation as a financing cash flow in the consolidated statements of cash flows.
