Item 2.02
Results of Operations and Financial Condition.
In connection with the resignation of John W. Chamberlain described below, and the costs associated therewith, American Assets Trust, Inc. (the “REIT”) and American Assets Trust, L.P. (together with the REIT, the “Company”) expects to record a severance charge of approximately $0.04 per diluted share in the third quarter of 2015 and the Company expects to update its 2015 guidance together with the release of third quarter earnings in November 2015.
The foregoing estimates are forward-looking and reflect management’s view of current and future market conditions, operating results and other factors described in the Company’s reports filed with the Securities and Exchange Commission. The Company’s actual results may differ materially from these estimates.
Item 5.02
Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.
Effective September 14, 2015, John W. Chamberlain ceased serving as President and Chief Executive Officer of the Company and resigned from the Board of Directors of the Company. Ernest W. Rady, the Company’s Executive Chairman, assumed the role of Chairman, President and Chief Executive Officer, effective September 14, 2015. The Company does not plan to replace Mr. Chamberlain at this time. Mr. Chamberlain tendered his resignation on September 10, 2015.
In connection with his separation from the Company, the Company and Mr. Chamberlain intend to enter into a release agreement, pursuant to which Mr. Chamberlain will be entitled to receive a lump sum cash separation payment in the amount of $2,402,242, continued health benefits at Company expense for a period of twelve months and accelerated vesting of 50% of his outstanding restricted stock awards (which will result in a total of 17,390 shares vesting).
Mr. Chamberlain’s receipt of the separation benefits is conditioned on his execution of the release agreement, which contains a general release of claims against the Company, as well as confidentiality, non-disparagement and other customary provisions.
The foregoing description of the release agreement is qualified in its entirety by reference to the full text of the release agreement, which will be filed as an exhibit to the Company’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2015.
