Development and Expansion Activities

During and subsequent to the quarter ended September 30, 2022, the Company acquired four land parcels located in the United States and UK for the potential development of nearly 800 sites, for an aggregate purchase price of $20.0 million. During the quarter and nine months ended September 30, 2022, the Company completed the construction of over 170 sites and over 300 sites, respectively, at two ground-up developments and six expansion properties.

Impact of Hurricane Ian

On September 28, 2022, Hurricane Ian made landfall on Florida's western coast. The storm primarily affected four properties in the Fort Myers area. Three RV properties, comprising approximately 2,500 sites, sustained significant flooding and wind damage from the hurricane, and the sea wall and certain docks at one marina were damaged. At other affected MH and RV properties, most of the damage was limited to trees, roofs, fences, skirting and carports. At other affected marina properties, docks, buildings, and landscaping sustained limited wind and water damage.

The Company recognized $29.9 million for impaired assets. The Company expects these charges to be partially offset by insurance recoveries, currently estimated at $17.7 million. The estimated net charges of $12.2 million are classified as Catastrophic event-related charges, net, in the Consolidated Statements of Operations. The Company maintains property, casualty, flood and business interruption insurance for its properties, subject to customary deductibles and limits. Expected insurance recoveries for loss of income and redevelopment costs greater than the impairment charges cannot be estimated at this time.

The foregoing impairment, expected insurance recovery, and net charge estimates are based on current information available, and the Company continues to assess these estimates. The actual final impairment, insurance recoveries and net charges could vary significantly from these estimates. Any changes to these estimates will be recognized in the period(s) in which they are determined.

BALANCE SHEET, CAPITAL MARKETS ACTIVITY AND OTHER ITEMS

Debt

As of September 30, 2022, the Company had $6.7 billion in debt outstanding with a weighted average interest rate of 3.4 percent and a weighted average maturity of 8.8 years. At September 30, 2022, the Company's net debt to trailing twelve-month Recurring EBITDA⁽¹⁾ ratio was 5.7 times.

Additionally, the Company has negotiated fixed rate mortgages with an existing lender on certain properties with existing loans that have low loan-to-value ratios and are scheduled to mature between 2026 and 2029. The additional financings are expected to close before year-end and provide proceeds to the Company of approximately $310.0 million. The Company intends to use the proceeds to repay borrowings outstanding under its senior credit facility.
