Biographical and other information regarding Ms. Cohn and Mr. Kimmel is set forth in Part III of the Partnership's Annual Report on [Form 10-K](http://www.sec.gov/Archives/edgar/data/../../../ix?doc=/Archives/edgar/data/0000926660/000162828025013828/airc-20241231.htm) for year ended December 31, 2024, filed with the Securities and Exchange Commission on March 19, 2025, and such information is incorporated by reference herein.
