Our casinos are our primary sources of income and operating cash flows and they were closed for approximately three months as a result of COVID-19. Since reopening, our casinos have performed well, though there can be no assurance that our reopened casinos will continue to generate sufficient cash flow from operations or that future borrowings will be available in amounts sufficient to enable us to pay our indebtedness or fund our other liquidity needs. In this section, we have described actions with respect to our liquidity that we have taken as a result of COVID-19.
Cash flows – operating activities. On a consolidated basis, cash used in operations during the six months ended June 30, 2020 was $6.4 million, compared to cash used in operations of $1.7 million in the prior-year period. Trends in our operating cash flows tend to follow trends in operating income, excluding non-cash charges, but are also affected by changes in working capital. Comparing the 2020 and 2019 periods, our operating cash flows decreased primarily due to the unforeseen business interruption from the COVID-19 pandemic. As discussed above, all of the Company’s casinos were closed for approximately three months beginning in mid-March 2020.
Cash flows – investing activities. On a consolidated basis, cash used in investing activities during the six months ended June 30, 2020 was $1.4 million, which primarily related to the garage construction at Bronco Billy’s that was suspended in March 2020 amidst the COVID-19 pandemic. Cash used in investing activities during the prior-year period was $3.1 million, which primarily related to capital expenditures for maintenance and certain growth-related projects, including the expansion at Bronco Billy’s and the remodeling of the Silver Slipper casino.
Cash flows – financing activities. On a consolidated basis, cash provided by financing activities during the six months ended June 30, 2020 was $4.4 million, compared to cash provided by financing activities of $8.1 million in the prior-year period. Comparing the 2020 and 2019 periods, we received proceeds totaling $5.6 million related to unsecured loans under the CARES Act in 2020 and the additional $10 million of incremental debt to our Notes was sold in May 2019, offset in both periods by payments for the Notes and the finance lease at Rising Star.
Other Factors Affecting Liquidity
We have significant outstanding debt and contractual obligations, in addition to potential future capital expenditures. Our principal debt matures in February 2024 and we anticipate needing to refinance this debt prior to its maturity, as we are unlikely to generate sufficient cash flow in the interim to completely repay these obligations. Certain planned capital expenditures designed to grow the Company, if pursued, would likely require additional financing, including perhaps the issuance of additional debt and potentially some form of equity financing, if available at such time. Our operations are subject to financial, economic, competitive, regulatory and other factors, many of which are beyond our control. If we are unable to generate sufficient operating cash flow and/or access the capital markets, including as a result of COVID-19, we could be required to adopt one or more alternatives, such as reducing, delaying, or eliminating certain planned capital expenditures, selling assets, obtaining additional equity financing, or borrowing at higher costs of capital. See “Bronco Billy’s Expansion Suspended” for measures that have been implemented as a result of COVID-19.
Long-term Debt. As discussed above in the “Executive Overview,” we executed the Waivers and Amendments in April 2020 and August 2020 to amend the Indenture governing the Notes, which included an amendment to delete our total leverage covenant requirement for the periods ended March 31, 2020 and June 30, 2020, among other items.
On February 2, 2018, we issued $100 million of Notes and on May 10, 2019, we issued an additional $10 million of Notes. The Notes are collateralized by substantially all of our assets and are guaranteed by all of our material subsidiaries. The total $110 million of Notes bear interest at the greater of the three-month LIBOR or 1.0%, plus a margin rate of 7.0%. The Indenture governing the Notes provides for a 50 basis point interest premium if Mr. Lee reduces his equity interests by 50% or more while serving as our CEO. Mr. Lee has no current intention to sell any shares. Interest on the Notes is payable quarterly in arrears, on March 31, June 30, September 30 and December 31 of each year until the Notes mature on February 2, 2024. On each interest payment date (as amended), we are required to make principal payments of $275,000 with a balloon payment for the remaining $103.5 million due upon maturity. The Waivers and Amendments also increased the amount due upon prepayment or maturity by a total of 40 basis points, applied to the aggregate principal amount of the Notes repaid. As of June 30, 2020, the total balance of the Notes was $107.4 million, currently accruing interest at a rate of 8.00%. Mandatory prepayments of the Notes will be required upon the occurrence of certain events, including sales of certain assets. We may redeem the Notes, in whole or in part, at any time at the applicable redemption price plus accrued and unpaid interest. The
