2023, our net cash flows used in financing activities were $13.9 million, primarily reflecting the payment of $14.0 million in cash dividends.
During the three months ended March 31, 2022, our net cash flows used in financing activities were $5.4 million.
Liquidity
At March 31, 2023, we had $318.5 million in unrestricted cash and $743.4 million available for borrowing in the aggregate under our revolving credit facility and the OEG revolving credit facility. During the three months ended March 31, 2023, we incurred capital expenditures of $36.8 million and paid $14.0 million in cash dividends. These changes, partially offset by the cash flows provided by operations discussed above, were the primary factors in the decrease in our cash balance from December 31, 2022 to March 31, 2023.
We anticipate investing in our operations during the remainder of 2023 by spending between approximately $175 million and $215 million in capital expenditures, which primarily includes enhancements at Gaylord Rockies to better position the property for our group customers, enhancements to the offerings at Block 21, the construction of Ole Red Las Vegas, and ongoing maintenance capital for each of our existing properties. In addition, we intend to contribute up to an additional $8.2 million in capital to the Circle joint venture for working capital needs. Further, our dividend policy provides that we will make minimum dividends of 100% of REIT taxable income annually. Future dividends are subject to our board of directors’ future determinations as to amount and timing. We currently have no debt maturities until July 2023. We believe we will be able to refinance our debt agreements prior to their maturities, including extension options.
We believe that our cash on hand and cash flow from operations, together with amounts available for borrowing under each of our revolving credit facility and the OEG revolving credit facility, will be adequate to fund our general short-term commitments, as well as: (i) current operating expenses, (ii) interest expense on long-term debt obligations, (iii) financing lease and operating lease obligations, (iv) declared dividends and (v) the capital expenditures described above. Our ability to draw on our credit facility and the OEG revolving credit facility is subject to the satisfaction of provisions of the credit facility, as amended, and the OEG revolving credit facility, as applicable.
Our outstanding principal debt agreements are described below. At March 31, 2023, there were no defaults under the covenants related to our outstanding debt.
