(1) Represents conversion of 34% of earned Performance Share Award Units (PSA Units) granted 1/28/2011, of which the earned amount was determined on 2/1/2012, based upon achievement of company and individual goals. After the earned amount was determined, the earned PSA Units have a vesting schedule of 34% on 1/28/2012, and 33% on each of 1/28/2013 and 1/28/2014. Earned PSA Units convert into Prologis common shares on a 1-for-1 basis, and have no exercise price or expiration date.
(2) Shares withheld for payment of the tax liability associated with the receipt of common stock acquired upon the vesting of the PSA Units and DEUs.
(3) PSA Units awarded 1/28/2011 were earned for the performance period from 1/1/2011 through 12/31/2011. This transaction represents the unvested portions of the earned PSA Units and DEUs that will continue to vest and payout in common shares on a 1-for-1 basis, 50% on each of 1/28/2013 and 1/28/2014.
(4) Restricted Share Units (RSUs) which vest 34% on 2/1/2013 and 33% on each of 2/1/2014 and 2/1/2015. The RSUs convert into Prologis common shares upon vesting on a 1-for-1 basis. RSUs have no exercise price or expiration date.
