The RSU grant vests in equal portions over a three year period, and are received by the Reporting Person upon vesting, on a one-for-one basis. This report reflects the vesting of one-third portion of the original RSU grant and the acquisition by the Reporting Person of the underlying shares minus sufficient shares withheld to pay applicable income taxes. The grant of Restricted Stock Units (RSUs), reported herein, entitles the Reporting Person to receive shares of the issuer common stock in equal installments of one-third of the original RSU grant on each of the first three anniversaries of the grant date. The RSUs automatically convert into shares of common stock on a one-for-one basis at no conversion cost to the Reporting Person. This Restricted Stock Units (RSUs) grant is issued pursuant to a provision of the issuers Management Stock Purchase Plan (MSPP) whereby, pursuant to an advanced election by the executive, he or she receives RSUs in lieu of a specified percentage or dollar amount of his or her annual incentive cash bonus. The RSUs are issued in whole units at a 33 percent discount from fair market value of the issuers common stock on the award date and generally vest 3 years from the date of the grant, at which time the RSUs convert into shares of common stock on a one-for-one basis unless the executive previously elected a longer deferral period.
