least the third quarter of 2021. As previously noted, operations continue to be suspended at one of the 18 Hotels, with the remainder operating at reduced, albeit increasing, capacities due to COVID-19; therefore, our traditional source of cash from operating activities has been significantly reduced. Despite these challenges, we believe that we have sufficient liquidity, as well as access to our credit facility and capital markets, to withstand the current decline in our operating cash flow. We expect our primary sources of cash will continue to be our working capital and credit facility, dispositions of hotel properties, and proceeds from public and private offerings of debt securities and common and preferred stock. However, there can be no assurance that the capital markets will be available to us in the future on favorable terms or at all.
We expect our primary uses of cash to be for operating expenses, including funding the cash flow needs at our hotels, capital investments in our hotels, repayment of principal on our notes payable and possibly on our unsecured debt, interest expense, dividends on our preferred stock and acquisitions of hotels or interests in hotels.
At this time, we do not expect to pay a quarterly common stock dividend in 2021. The resumption in quarterly common stock dividends will be determined by our board of directors after considering our obligations under our various financing agreements, projected taxable income, compliance with our debt covenants, long-term operating projections, expected capital requirements and risks affecting our business. We have taken additional steps to preserve our liquidity, including the deferral of portions of our planned 2021 non-essential capital improvements into our portfolio, as well as the temporary suspension of our stock repurchase program.
In April 2021, we acquired the Montage Healdsburg for $265.0 million. We funded the acquisition with $198.8 million of cash on hand and through the issuance of 2,650,000 shares of our Series G preferred stock with an aggregate liquidation preference of $66.3 million. The Series G preferred stock, which is callable at the liquidation preference plus accrued and unpaid dividends by us at any time, accrues dividends at an initial rate equal to the Montage Healdsburg’s annual net operating income yield on our investment in the hotel. The Series G preferred stock is not convertible into any other security.
In May 2021, we issued 4,600,000 shares of our 6.125% Series H preferred stock for gross proceeds of $115.0 million. The Series H preferred stock has a redemption price of $25.00 per share, and can be redeemed by us on or after May 24, 2026. We used the proceeds received from this issuance to redeem all 4,600,000 shares of our 6.950% Series E preferred stock. Because the redemption of the Series E preferred stock was a redemption in full, trading of the Series E preferred stock on the New York Stock Exchange ceased on the June 11, 2021 redemption date.
In June 2021, we utilized our February 2017 ATM Program to issue 2,913,682 shares of our common stock for gross proceeds of $38.4 million, leaving $137.0 million available for sale under the February 2017 ATM Program.
In July 2021, we issued 4,000,000 shares of our 5.70% Series I Cumulative Redeemable Preferred Stock (the “Series I preferred stock”) for gross proceeds of $100.0 million. The Series I preferred stock has a redemption price of $25.00 per share, and can be redeemed by us on or after July 16, 2026. We expect to use $75.0 million of the proceeds received from this issuance to redeem all 3,000,000 shares of our 6.450% Series F preferred stock in August 2021.
We believe that the steps we have taken to maintain an appropriate cash position and preserve our financial flexibility, combined with the amendments to our unsecured debt, our already strong balance sheet and our low leverage will be sufficient to allow us to navigate through this crisis. Given the unprecedented impact of COVID-19 on the global market and our hotel operations, we cannot, however, assure you that our forecast or the assumptions we used to estimate our liquidity requirements will be correct. In addition, the magnitude and duration of the COVID-19 pandemic is uncertain. We cannot accurately estimate the impact on our business, financial condition or operational results with reasonable certainty.
Cash Balance. As of June 30, 2021, our unrestricted cash balance was $162.9 million. We believe that our current unrestricted cash balance and our ability to draw the $500.0 million of capacity available for borrowing under the unsecured revolving credit facility will enable us to successfully manage our Company while operations at the 18 Hotels are either reduced or temporarily suspended.
Certain of our loan agreements contain cash trap provisions that may be triggered if the performance of the hotels securing the loans decline. These provisions were triggered for the loans secured by the Embassy Suites La Jolla and the JW Marriott New Orleans in January 2021, and at the Hilton San Diego Bayfront in May 2021. As of June 30, 2021, only a nominal amount of excess cash was held in lockbox accounts for the benefit of the lenders and included in restricted cash on our consolidated balance sheet. The cash trap provisions triggered on these three loans will remain until the hotels reach profitability levels that terminate the cash traps.
Debt. As of June 30, 2021, we had $746.3 million of consolidated debt, $210.4 million of cash and cash equivalents, including restricted cash, and total assets of $3.0 billion. We believe that by maintaining appropriate debt levels, staggering maturity dates and maintaining a highly flexible structure, we will have lower capital costs than more highly leveraged companies, or companies with limited flexibility due to restrictive corporate-level financial covenants.
