Liquidity and Capital Resources
Our primary funding requirements are for our ongoing operations, capital expenditures, outstanding debt obligations, including lease agreements, and strategic investments. At March 31, 2022 the principal amount of our outstanding consolidated debt aggregated to $740.3 million, of which $18.1 million is classified as current in our unaudited condensed consolidated balance sheet as of such date. As of March 31, 2022, we had borrowing capacity of $245.6 million under our new Revolving Credit Facility. We are required to prepay principal amounts if we generate excess cash flow, as defined in the Credit Agreement.
Our primary funding requirements are for our ongoing operations, capital expenditures, outstanding debt obligations, including lease agreements, and strategic investments. As of March 31, 2022, we had $190.7 million of cash and cash equivalents. We believe that our existing cash balances, available borrowing capacity under our Revolving Credit Facility, and operating cash flows will provide sufficient resources to fund our obligations and anticipated liquidity requirements over the next 12 months.
We expect to utilize free cash flow and cash on hand as funding sources, as well as potentially engage in future refinancing transactions to further extend the maturities of our debt obligations. The timing and terms of any refinancing transactions will be subject to market conditions among other considerations.
As potential acquisitions or dispositions arise, we actively review such transactions against our objectives including, among other considerations, improving our operational efficiency, geographic clustering of assets, product development or technology capabilities of our business and achieving appropriate strategic objectives, and we may participate in such transactions to the extent we believe these possibilities present attractive opportunities. However, there can be no assurance that we will actually complete any acquisitions or dispositions, or that any such transactions will be material to our operations or results.
Our ability to fund operations, make capital expenditures, repay debt obligations and make future acquisitions and strategic investments depends on future operating performance and cash flows, which are subject to prevailing economic conditions and to financial, business and other factors, some of which are beyond our control.
Historical Operating, Investing, and Financing Activities
Operating Activities
Net cash provided by operating activities decreased from $77.6 million for the three months ended March 31, 2021 to $49.4 million for the three months ended March 31, 2022. The decrease is primarily due to the reduction in operating income, including the impact from the aforementioned sale, and timing differences of our receivables and payables, partially offset by the decrease in interest paid.
Investing Activities
Net cash used in investing activities was $58.9 million for the three months ended March 31, 2021 and $41.6 million for the three months ended March 31, 2022. The decrease is primarily attributable to a decrease in capital expenditures relating to our smaller footprint following the sales of our service areas.
We have ongoing capital expenditure requirements related to the maintenance, expansion and technological upgrades of our network. Capital expenditures are funded primarily through a combination of cash on hand and cash flow from operations. Our capital expenditures from continuing operations were $42.1 million and $44.0 million for the three months ended March 31, 2022 and 2021, respectively. The $1.9 million decrease from the three months ended March 31, 2021 to the three months ended March 31, 2022 is related to a reduction in customer premise equipment (“CPE”) and network enhancement expenditures partially offset by increases in line extensions as we focus on expanding our network.
