Definitions and Notes

Capital Expenditures and Investment Activity - The Company classifies its investments in properties into the following categories:

Recurring Capital Expenditures - Property recurring capital expenditures are necessary to maintain asset quality, including purchasing and replacing assets used to operate the communities and marinas. Recurring capital expenditures at the Company's MH and RV properties include items such as: major road, driveway and pool improvements; clubhouse renovations; adding or replacing streetlights; playground equipment; signage; maintenance facilities; manager housing and property vehicles. Recurring capital expenditures at the Company's marinas include items such as: dredging, dock repairs and improvements, and equipment maintenance and upgrades. The minimum capitalized amount is five hundred dollars.
Non-Recurring Capital Expenditures - The following investment and reinvestment activities are non-recurring in nature:
- Lot Modifications - Lot modification capital expenditures are incurred to modify the foundational structures required to set a new home after a previous home has been removed. These expenditures are necessary to create a revenue stream from a new site renter and often improve the quality of the community. Other lot modification expenditures include land improvements added to annual RV sites to aid in the conversion of transient RV guests to annual contracts. See page 12 for move-out rates.
- Growth Projects - Growth projects consist of revenue-generating or expense-reducing activities at MH, RV and marina properties. These include, but are not limited to, utility efficiency and renewable energy projects, site, slip or amenity upgrades such as the addition of a garage, shed or boat lift, and other special capital projects that substantiate an incremental rental increase.
- Rebranding - Rebranding includes new signage at the Company's RV communities and costs of building an RV mobile application and updated website.
- Acquisitions - Capital expenditures related to acquisitions represent the purchase price paid for the existing operating properties and land parcels for future ground-up development and expansions activities (detailed for the current calendar year on page 13), plus the capital improvements identified during due diligence that will be needed to bring acquired properties up to the Company's operating standards.

For the quarter ended March 31, 2023, the components of total acquisition investment are as follows (in millions):

	Quarter Ended March 31, 2023

^(b)Includes the value allocated to infrastructure improvements associated with acquired land, when applicable.

Improvements subsequent to acquisition include upgrading clubhouses; landscaping; new street light systems; new mail delivery systems; pool renovations including larger decks, heaters and furniture; new maintenance facilities; lot modifications; and new signage including main signs and internal road signs. These are considered acquisition costs and although identified during due diligence, often require 24 to 36 months after closing to complete.

Expansions and Developments - Expansion and development expenditures consist primarily of construction costs such as roads, activities, and amenities, and costs necessary to complete home and RV site improvements, such as driveways, sidewalks and landscaping at the Company's MH and RV communities. Expenditures also include costs to rebuild after damage has been incurred at MH, RV or marina properties, and research and development.

Non-GAAP Supplemental Measures

Investors and analysts following the real estate industry use non-GAAP supplemental performance measures, including net operating income ("NOI"), earnings before interest, tax, depreciation and amortization ("EBITDA") and funds from operations ("FFO") to assess REITs. The Company believes that NOI, EBITDA and FFO are appropriate measures given their wide use by and relevance to investors and analysts. Additionally, NOI, EBITDA and FFO are commonly used in various ratios, pricing multiples, yields and returns and valuation calculations used to measure financial position, performance and value.

NOI provides a measure of rental operations that does not factor in depreciation, amortization and non-property specific expenses such as general and administrative expenses.

EBITDA provides a further measure to evaluate ability to incur and service debt; EBITDA also provides further measures to evaluate the Company's ability to fund dividends and other cash needs.

FFO, reflecting the assumption that real estate values rise or fall with market conditions, principally adjusts for the effects of GAAP depreciation and amortization of real estate assets.

Net Operating Income ("NOI")
- Total Portfolio NOI - The Company calculates NOI by subtracting property operating expenses and real estate taxes from operating property revenues. NOI is a non-GAAP financial measure that the Company believes is helpful to investors as a supplemental measure of operating performance because it is an indicator of the return on property investment and provides a method of comparing property performance over time. The Company uses NOI as a key measure when evaluating performance and growth of particular properties and / or groups of properties. The principal limitation of NOI is that it excludes depreciation, amortization, interest expense and non-property specific expenses such as general and administrative expenses, all of which are significant costs. Therefore, NOI is a measure of the operating performance of the properties of the Company rather than of the Company overall. The Company believes that NOI provides enhanced comparability for investor evaluation of properties performance and growth over time.

The Company believes that GAAP net income (loss) is the most directly comparable measure to NOI. NOI should not be considered to be an alternative to GAAP net income (loss) as an indication of the Company's financial performance or GAAP cash flow from operating activities as a measure of the Company's liquidity; nor is it indicative of funds available for the Company's cash needs, including its ability to make cash distributions. Because of the inclusion of items such as interest, depreciation and amortization, the use of GAAP net income (loss) as a performance measure is limited as these items may not accurately reflect the actual change in market value of a property, in the case of depreciation and in the case of interest, may not necessarily be linked to the operating performance of a real estate asset, as it is often incurred at a parent company level and not at a property level.

Same Property NOI - This is a key management tool used when evaluating performance and growth of the Company's Same Property portfolio. The Company believes that Same Property NOI is helpful to investors as a supplemental comparative performance measure of the income generated from the Same property portfolio from one period to the next. Same Property NOI does not include the revenues and expenses related to home sales, service, retail, dining and entertainment activities at the properties.

Earnings before interest, tax, depreciation and amortization ("EBITDA")
- EBITDAre - NAREIT refers to EBITDA as "EBITDAre" and calculates it as GAAP net income (loss), plus interest expense, plus income tax expense, plus depreciation and amortization, plus or minus losses or gains on the disposition of depreciated property (including losses or gains on change of control), plus impairment write-downs of depreciated property and of investments in nonconsolidated affiliates caused by a decrease in value of depreciated property in the affiliate, and adjustments to reflect the entity's share of EBITDAre of nonconsolidated affiliates. EBITDAre is a non-GAAP financial measure that the Company uses to evaluate its ability to incur and service debt, fund dividends and other cash needs and cover fixed costs. Investors utilize EBITDAre as a supplemental measure to evaluate and compare investment quality and enterprise value of REITs. Investors utilize EBITDAre as a supplemental measure to evaluate and compare investment quality and enterprise value of REITs.
- Recurring EBITDA - The Company also uses EBITDAre excluding certain gain and loss items that management considers unrelated to measurement of the Company's performance on a basis that is independent of capital structure ("Recurring EBITDA"). The Company believes that GAAP net income (loss) is the most directly comparable measure to EBITDAre. EBITDAre is not intended to be used as a measure of the Company's cash generated by operations or its dividend-paying capacity, and should therefore not replace GAAP net income (loss) as an indication of the Company's financial performance or GAAP cash flow from operating, investing and financing activities as measures of liquidity.
Funds from Operations - ("FFO")
- FFO - NAREIT defines FFO as GAAP net income (loss), excluding gains (or losses) from sales of depreciable operating property, plus real estate related depreciation and amortization, real estate related impairments, and after adjustments for nonconsolidated partnerships and joint ventures. FFO is a non-GAAP financial measure that management believes is a useful supplemental measure of the Company's operating performance. By excluding gains and losses related to sales of previously depreciated operating real estate assets, real estate related impairment and real estate asset depreciation and amortization (which can vary among owners of identical assets in similar condition based on historical cost accounting and useful life estimates), FFO provides a performance measure that, when compared period-over-period, reflects the impact to operations from trends in occupancy rates, rental rates and operating costs, providing perspective not readily apparent from GAAP net income (loss). Management believes the use of FFO has been beneficial in improving the understanding of operating results of REITs among the investing public and making comparisons of REIT operating results more meaningful.
- Core FFO - In addition to FFO, the Company uses FFO excluding certain gain and loss items that management considers unrelated to the operational and financial performance of the Company's core business ("Core FFO"). The Company believes that Core FFO provides enhanced comparability for investor evaluations of period-over-period results.

The Company believes that GAAP net income (loss) is the most directly comparable measure to FFO. The principal limitation of FFO is that it does not replace GAAP net income (loss) as a financial performance measure or GAAP cash flow from operating activities as a measure of the Company's liquidity. Because FFO excludes significant economic components of GAAP net income (loss) including depreciation and amortization, FFO should be used as a supplement to GAAP net income (loss) and not as an alternative to it. Furthermore, FFO is not intended as a measure of a REIT's ability to meet debt principal repayments and other cash requirements, nor as a measure of working capital. FFO is calculated in accordance with the Company's interpretation of standards established by NAREIT, which may not be comparable to FFO reported by other REITs that interpret the NAREIT definition differently.

Utility Revenue - Results for the Company's Same Property portfolio net certain utility revenue against the related utility expense in Property operating expense as follows (in millions):

	Quarter Ended March 31, 2023								Quarter Ended March 31, 2022
	MH		RV		Marina		Total		MH		RV		Marina		Total
Utility revenue netted against related utility expense	$	18.2	$	4.1	$	5.0	$	27.3	$	16.1	$	3.9	$	4.2	$	24.2
