As of September 30, 2024, we had seven floating-rate debt-related investments with a weighted-average interest rate of 9.5% and a weighted-average remaining life of 1.1 years. As of September 30, 2024, the aggregate outstanding principal was $313.4 million, the aggregate carrying amount was $312.3 million and total aggregate commitments were up to $357.2 million.
As of September 30, 2024, we had three available-for-sale debt securities, which were comprised of one CRE CLO, one CMBS and one preferred equity investment. As of September 30, 2024, the aggregate fair value of these investments was $134.0 million.
We currently focus our investment activities primarily across the major U.S. property sectors (residential (which includes and/or may include multi-family and other types of rental housing such as manufactured, student and single-family rental housing), industrial, retail and office (which includes and/or may include medical office and life science laboratories)), self-storage properties and investments in real estate debt and securities. To a lesser extent, we strategically invest in and/or intend to invest in geographies outside of the U.S., which may include Canada, Mexico, the United Kingdom, Europe and other foreign jurisdictions, and in other sectors such as triple net lease, properties in sectors adjacent to our primary investment sectors and/or infrastructure, to create a diversified blend of current income and long-term value appreciation. Our near-term investment strategy is likely to prioritize new investments in the residential, industrial and self-storage sectors due to relatively attractive fundamental conditions. We also intend to continue to hold an allocation of properties in the retail and office sectors, the former of which is largely grocery-anchored.
Net Asset Value
Our board of directors, including a majority of our independent directors, has adopted valuation procedures, as amended from time to time, that contain a comprehensive set of methodologies to be used in connection with the calculation of our NAV. With the approval of our board of directors, including a majority of our independent directors, we have engaged Altus Group U.S. Inc., a third-party valuation firm, to serve as our independent valuation advisor (“Altus Group” or the “Independent Valuation Advisor”) with respect to helping us administer the valuation and review process for the real properties in our portfolio, providing monthly real property appraisals and valuations for certain of our debt-related assets, reviewing annual third-party real property appraisals, reviewing the internal valuations of DST Program Loans and debt-related liabilities performed by our Advisor, providing quarterly valuations of our properties subject to master lease obligations associated with the DST Program, and assisting in the development and review of our valuation procedures. See Exhibit 4.5 of this Quarterly Report on Form 10-Q for a more detailed description of our valuation procedures, including important disclosure regarding real property valuations provided by the Independent Valuation Advisor.
Our valuation procedures, which address specifically each category of our assets and liabilities and are applied separately from the preparation of our financial statements in accordance with GAAP, involve adjustments from historical cost. There are certain factors which cause NAV to be different from total equity or stockholders’ equity on a GAAP basis. Most significantly, the valuation of our real assets, which is the largest component of our NAV calculation, is provided to us by the Independent Valuation Advisor. For GAAP purposes, these assets are generally recorded at depreciated or amortized cost. Another example that will cause our NAV to differ from our GAAP total equity or stockholders’ equity is the straight-lining of rent, which results in a receivable for GAAP purposes that is not included in the determination of our NAV. The fair values of our assets and certain liabilities are determined using widely accepted methodologies and, as appropriate, the GAAP principles within the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification under Topic 820, Fair Value Measurements and Disclosures and are used by ALPS in calculating our NAV per share. However, our valuation procedures and our NAV are not subject to GAAP and will not be subject to independent audit. We did not develop our valuation procedures with the intention of complying with fair value concepts under GAAP and, therefore, there could be differences between our fair values and the fair values derived from the principal market or most advantageous market concepts of establishing fair value under GAAP. The aggregate real property valuation of $5.06 billion compares to a GAAP basis of real properties (net of intangible lease liabilities and before accumulated amortization and depreciation) of $4.86 billion, representing a difference of approximately $207.0 million, or 4.3%.
As used below, “Fund Interests” means our outstanding shares of common stock, along with OP Units, which may be or were held directly or indirectly by the Advisor, the Former Sponsor, members or affiliates of the Former Sponsor, and third parties, and “Aggregate Fund NAV” means the NAV of all the Fund Interests.
