In July 2017, the Financial Conduct Authority (“FCA”) that regulates LIBOR announced it intends to stop compelling banks to submit rates for the calculation of LIBOR after 2021. As a result, the Federal Reserve Board and the Federal Reserve Bank of New York organized the Alternative Reference Rates Committee (“ARRC”), which identified the Secured Overnight Financing Rate (“SOFR”) as its preferred alternative rate for LIBOR in derivatives and other financial contracts. We are not able to predict when LIBOR will cease to be available or when there will be sufficient liquidity in the SOFR markets. Any changes adopted by the FCA or other governing bodies in the method used for determining LIBOR may result in a sudden or prolonged increase or decrease in reported LIBOR. If that were to occur, our interest payments could change. In addition, uncertainty about the extent and manner of future changes may result in interest rates and/or payments that are higher or lower than if LIBOR were to remain available in the current form.
LIBOR is expected to be phased out or modified by June 2023, and the writing of contracts using LIBOR is expected to stop by the end of 2021. As of September 30, 2021, our line of credit, term loans, and $209.3 million mortgage note are our only consolidated indebtedness with initial or extended maturity dates beyond 2023 that have exposure to LIBOR. The agreements governing the term loans provide procedures for determining a replacement or alternative base rate in the event that LIBOR is discontinued. However, there can be no assurances as to whether such replacement or alternative base rate will be more or less favorable than LIBOR. As of September 30, 2021, we have interest rate swaps in place to hedge LIBOR on $350.0 million of commitments under our $415.0 million term loan and on $225.0 million of commitments under our $600.0 million term loan. Additionally, we have one interest rate cap in place on $170.0 million of borrowings under our $209.3 million mortgage note, as of September 30, 2021. We intend to monitor the developments with respect to the potential phasing out of LIBOR after 2023 and work with our lenders to seek to ensure any transition away from LIBOR will have minimal impact on our financial condition, but can provide no assurances regarding the impact of the discontinuation of LIBOR.
Mortgage Notes. As of September 30, 2021, we had property-level borrowings of approximately $377.0 million of principal outstanding with a weighted-average remaining term of 4.5 years. These borrowings are secured by mortgages or deeds of trust and related assignments and security interests in the collateralized properties, and had a weighted-average interest rate of 2.27%. Refer to “Note 6 to the Condensed Consolidated Financial Statements” for additional information regarding the mortgage notes.
Debt Covenants. Our line of credit, term loan and mortgage note agreements contain various property-level covenants, including customary affirmative and negative covenants. In addition, the agreements governing our line of credit and term loans contain certain corporate level financial covenants, including leverage ratio, fixed charge coverage ratio, and tangible net worth thresholds. These covenants may limit our ability to incur additional debt, to make borrowings under our line of credit, or to pay distributions. We were in compliance with all of our debt covenants as of September 30, 2021.
Leverage. We use financial leverage to provide additional funds to support our investment activities. We may finance a portion of the purchase price of any real estate asset that we acquired with borrowings on short or long-term basis from banks, institutional investors and other lenders. We calculate our leverage for reporting purposes as the outstanding principal balance of our borrowings divided by the fair value of our real property plus our investment in our unconsolidated joint venture partnership plus cash and cash equivalents. We had leverage of 32.8% as of September 30, 2021. Our management believes our strong equity raise and the timing of our deployment of capital accounts for our lower leverage as of September 30, 2021 and expects that as we deploy capital going forward, our leverage will near approximately 50%.
Offering Proceeds. As of September 30, 2021, aggregate gross proceeds raised since inception from our public offerings, including proceeds raised through our distribution reinvestment plan, were $2.50 billion ($2.40 billion net of direct selling costs).
Distributions. We intend to continue to accrue and make distributions on a regular basis. For the nine months ended September 30, 2021, approximately 47.0% of our total gross distributions were paid from cash flows from operating activities, as determined on a GAAP basis, and 53.0% of our total gross distributions were funded from sources other than cash flows from operating activities, as determined on a GAAP basis; specifically, 2.5% were funded with proceeds from financing activities, and 50.5% of our total gross distributions were funded with proceeds from shares issued pursuant to our distribution reinvestment plan. Some or all of our future distributions may be paid from sources other than cash flows from operating activities, such as cash flows from financing activities, which include borrowings (including borrowings secured by our assets), proceeds from the issuance of shares pursuant to our distribution reinvestment plan, proceeds from sales of assets, interest income from our cash balances, and the net proceeds from primary shares sold in our public offerings. We have not established a cap on the amount of our distributions that may be paid from any of these sources. The amount of any distributions will be determined by our board of directors, and will depend on, among other things, current and projected cash requirements, tax considerations and other factors deemed relevant by our board.
For the fourth quarter of 2021, our board of directors authorized monthly distributions to all common stockholders of record as of the close of business on the last business day of each month for the fourth quarter of 2021, or October 31, 2021, November 30, 2021 and December 31, 2021 (each a “Distribution Record Date”). The distributions were authorized at a quarterly rate of (i) $0.13625 per Class I share of common stock and (ii) $0.13625 per Class T share and per Class W share of common stock, less the respective annual distribution fees that are payable monthly with respect to such Class T shares and Class W shares. This quarterly rate is equal to a monthly rate of (i) $0.04542 per Class I share of common stock and (ii) $0.04542 per Class T share and per Class W share of common stock, less the respective annual distribution fees that are payable with respect to such Class T shares and Class W shares. Distributions for each month of the fourth quarter of 2021 have been or will be paid in cash or reinvested in shares of our common stock for those electing to participate in our distribution reinvestment plan following the close of business on the respective Distribution Record Date applicable to such monthly distributions.
