On July 5, 2012, Equity LifeStyle Properties, Inc. (the “Company”) issued a news release announcing that, after almost 20 years of outstanding service, Ellen Kelleher, Executive Vice President-Property Management, has decided to retire on December 31, 2012; that until then she will transition her duties to others; and other changes to its management team. That news release is attached as Exhibit 99.1 to this report on Form 8-K.

The Company has elevated the three most senior property management officers who currently report to Ms. Kelleher as follows: Peter Underhill has been appointed Senior Vice President-Revenue Management, Ron Bunce has been appointed Senior Vice President West Operations, and Brad Nelson has been appointed Senior Vice President East Operations. Mr. Underhill, Mr. Bunce and Mr. Nelson will each now report directly to Chief Executive Officer Tom Heneghan. Mr. Heneghan, in addition to his other responsibilities as CEO, will assume overall responsibility for the property management function. Marguerite Nader, the Company’s president and chief financial officer, will also continue to report to Mr. Heneghan.

Mr. Underhill, age 57, originally joined the Company in 1994. He has served in a variety of roles, including most recently overseeing California and Colorado properties, resident leasing and renewals, and the home rental program. In his new role, Mr. Underhill will have responsibility for supervising revenue management throughout the country, including lease administration and customer information.

Mr. Bunce, age 55, has been with the Company since 1999. He has served in a variety of roles, including most recently as a Regional Vice President of Operations. In his new role, Mr. Bunce will have day-to-day responsibility for property operations in the western region of the country.

Mr. Nelson, age 57, has been with the Company since 2008 serving as a Regional Vice President of Operations. Before joining the Company, Mr. Nelson had been with Thousand Trails and related companies since 1985, serving among other roles as Thousand Trails’ Vice President of Operations for all properties. In his new role, Mr. Nelson will have day-to-day responsibility for property operations in the eastern region of the country.

In addition, the Company has appointed Seth Rosenberg Senior Vice President of Marketing, Jim Phillips Senior Vice President of Sales, and Dave Kozy Vice President of Customer Relations. Mr. Rosenberg, Mr. Phillips and Mr. Kozy will each report directly to Ms. Nader. Ms. Nader, in addition to her other responsibilities as President and CFO, will assume overall responsibility for the sales and marketing function.

Mr. Phillips, age 63, has been with the Company since 2008. He served most recently as Vice President of Sales and Membership Marketing. Before joining the Company, Mr. Phillips had been with Thousand Trails and related companies, which he originally joined in 1984, serving among other roles as Thousand Trails’ Senior Vice President of Sales. In his new role, Mr. Phillips will oversee all sales activity.

Mr. Kozy, age 52, has been with the Company since 2004. He has served in a variety of roles, including most recently as Vice President directing the operations of the Company’s RV Home and Marine Solutions subsidiary. In his new role, Mr. Kozy will oversee all customer relations activity.

In order to achieve closer comparability with the compensation of the sales and marketing officers who report directly to Ms. Nader, the Company has adjusted the compensation of Mr. Rosenberg, who previously served as Senior Vice President of Sales and Marketing and on the management committee. Mr. Rosenberg will no longer be eligible to vest in the restricted stock awarded on January 31, 2012 and his bonus potential will be 50% of his current base salary.
