Alaska Transaction. On July 22, 2021, Alaska Communications entered into a new debt financing in connection with the Alaska Transaction. See Acquisition of Alaska Communications System Group, Inc.
We continue to explore opportunities to expand our telecommunications business or acquire new businesses and telecommunications licenses in the United States, the Caribbean and elsewhere. Such acquisitions may require external financing. While there can be no assurance as to whether, when or on what terms we will be able to acquire any such businesses or licenses or make such investments, such acquisitions may be completed through the issuance of shares of our capital stock, payment of cash or incurrence of additional debt. From time to time, we may raise capital ahead of any definitive use of proceeds to allow us to move more quickly and opportunistically if an attractive investment materializes.
Cash used in investing activities. Cash used in investing activities increased by $49.4 million to $74.7 million from $25.3 million for the six months ended June 30, 2022 and 2021, respectively. Capital expenditures for the six months ended June 30, 2022 and 2021 were $75.1 million and $41.9 million, respectively. Of these capital expenditure amounts, $3.9 million and $6.5 million for the six months ended June 30, 2022 and 2021, respectively, are reimbursable. We also incurred expenditures of $1.4 million and $5.2 million during the six months ended June 30, 2022 and 2021, respectively, for strategic investments. Partially offsetting these expenditures were cash receipts of $1.8 million and $18.6 million during the six months ended June 30, 2022 and 2021, respectively, for the proceeds from the Vibrant Transaction and a receipt of $3.3 million during the six months ended June 30, 2021 for certain government grants.
Cash provided by (used in) financing activities. Our financing activities provided us with $15.4 million during the six months ended June 30, 2022. For the six months ended June 30, 2021, we used $11.2 million for our financing activities. The net change of $26.6 million was primarily a result of an increase in borrowings from our credit facilities of $39.4 million partially offset by the increase in our repayments under those facilities of $25.4 million. Other significant changes in financing activities included the decreases in payments made for the repurchase of noncontrolling interests in our less than wholly-owned subsidiaries, distributions made to the minority stockholders of our less than wholly-owned subsidiaries and the repurchase of our common stock of $8.2 million, $3.1 million and $1.3 million, respectively.
Working Capital. Historically, we have internally funded our working capital needs. Pursuant to the FirstNet Agreement, AT&T has the option to repay construction costs, with interest, over an eight-year period. To fund the working capital needs created by AT&T’s option to extend its payment terms, we completed the Receivables Credit Facility, as discussed below, on March 26, 2020.
Capital expenditures. Historically, a significant use of our cash has been for capital expenditures to expand and upgrade our telecommunications networks and to expand our previously owned renewable energy operations.
For the six months ended June 30, 2022 and 2021, we spent approximately $75.1 million and $41.9 million, respectively, on capital expenditures relating to our telecommunications networks and our business support systems of which $3.9 million and $6.5 million, respectively, are reimbursable. The following notes our capital expenditures, by operating segment, for these periods (in thousands):

We are continuing to invest in our telecommunication networks along with our operating and business support systems in many of our markets. Such investments primarily relate to the upgrade and expansion of our networks and are expected to total approximately $150 million to $160 million, net of reimbursable amounts, for the full year 2022.
We expect to fund our current capital expenditures primarily from our current cash balances, cash generated from operations and our existing credit facilities including the Receivables Credit Facility.
