To mitigate this risk, we monitor our investments through a variety of methods determined by the type of property. Our asset management process for seniors housing properties generally includes review of monthly financial statements and other operating data for each property, review of obligor/partner creditworthiness, property inspections and review of covenant compliance relating to licensure, real estate taxes, letters of credit and other collateral. Our internal property management division manages and monitors the outpatient medical portfolio with a comprehensive process, including review of tenant relations, lease expirations, the mix of health service providers, hospital/health system relationships, property performance, capital improvement needs and market conditions, among other things. We evaluate the operating environment in each property’s market to determine the likely trend in operating performance of the facility. When we identify unacceptable trends, we seek to mitigate, eliminate or transfer the risk. Through these efforts, we generally aim to intervene at an early stage to address any negative trends, and in so doing, support both the collectability of revenue and the value of our investment.

For the year ended December 31, 2024, resident fees and services and rental income represented 75% and 20% of total revenues, respectively. Substantially all of our operating leases are designed with escalating rent structures. Leases with fixed annual rental escalators are generally recognized on a straight-line basis over the initial lease period, subject to a collectability assessment. Rental income related to leases with contingent rental escalators is generally recorded based on the contractual cash rental payments due for the period. Our yield on loans receivable depends upon a number of factors, including the stated interest rate, the average principal amount outstanding during the term of the loan and any interest rate adjustments.

We also continuously evaluate opportunities to finance future investments. New investments are generally funded from temporary borrowings under our unsecured revolving credit facility and commercial paper program, internally generated cash and the proceeds from investment dispositions. Our investments generate cash from NOI and principal payments on loans receivable. Permanent financing for future investments, which replaces funds drawn under our unsecured revolving credit facility and commercial paper program, has historically been provided through a combination of the issuance of debt and equity securities and the incurrence or assumption of secured debt. Given the general economic conditions during 2023 and 2024, investments were generally funded proactively via issuances of common stock.

The following is a summary of our results of operations for the Triple-net segment for the years presented (in thousands):

Previous wording

Rental income decreased primarily due to agreements to convert Triple-net properties to Seniors Housing Operating RIDEA structures and the write-off of straight-line rent receivable balances of $139,652,000 and $16,642,000 during the years ended December 31, 2024 and 2023, respectively. These write-offs relate to leases for which the collection of substantially all contractual lease payments was no longer deemed probable, due primarily to agreements reached to convert Triple-net properties to Seniors Housing Operating RIDEA structures. These decreases are partially offset by acquisitions during the relevant periods.

Current wording

The increase in rental income is primarily related to acquisitions that occurred during the year ended December 31, 2025. See Note 3 to our consolidated financial statements for additional information. Additionally, during the year ended December 31, 2024, we recognized a write-off of straight-line rent receivable and unamortized lease incentive balances of $139,652,000 related to leases for which the collection of substantially all contractual lease payments was no longer deemed probable due primarily to agreements reached to convert Triple-net properties to Seniors Housing Operating RIDEA structures.

Previous wording

Certain of our leases contain annual rental escalators that are contingent upon changes in the Consumer Price Index and/or changes in the gross operating revenues of the tenant’s properties. These escalators are not fixed, so no straight-line rent is recorded; however, rental income is recorded based on the contractual cash rental payments due for the period. If gross operating revenues at our facilities and/or the Consumer Price Index do not increase, a portion of our revenues may not continue to increase. For the year ended December 31, 2024, we had 64 leases with rental rate increases ranging from 0.05% to 20.05% in our Triple-net portfolio.
