Purchases of property, plant, and equipment and acquisitions (refer to Note F for Business Combinations) and comprised most of our cash used in investing activities during the first three months of 2022 and totaled $32.1 million and $24.6 million, respectively. Total proceeds from the sales of property, plant, and equipment were $1.2 million. Outstanding purchase commitments on existing capital projects totaled approximately $68.7 million on March 26, 2022. Capital spending primarily consists of several projects to expand capacity to manufacture new and value-added products, achieve efficiencies through automation, make improvements to a number of facilities, and increase our transportation capacity (tractors, trailers) in order to meet higher volumes and replace old rolling stock. We intend to fund capital expenditures and purchase commitments through our operating cash flows for the balance of the year. We currently plan to spend between $175 million to $225 million on capital projects for the year with variability due to uncertainty about supplier lead times. Notable areas of capital spending include projects to increase the capacity and efficiency of our plants that produce our Deckorators mineral-based composite and wood-plastic composite decking and our UFP Edge siding, pattern and trim products, expand the capacity of machine-built pallet and site-built business units, and take advantage of automation opportunities.
Cash flows from financing activities primarily consisted of net borrowings of debt of approximately $101.5 million, the payment of quarterly dividends totaling $12.5 million ($0.20 per share), cash paid for repurchases of common stock of $0.5 million, and distributions to noncontrolling interests of $2.1 million. On April 20, 2022, our board of directors approved an increase in our second quarter dividend to $0.25 per share, payable on June 15, 2022, to shareholders of record on June 1, 2022. Additionally, in April 2022, we repurchased approximately 756,000 shares for $58.5 million, at an average share price of $77.40.
On March 26, 2022, we had $109.7 million outstanding on our $550 million revolving credit facility, and we had approximately $433.2 million in remaining availability after considering $7.1 million in outstanding letters of credit. Financial covenants on the unsecured revolving credit facility and unsecured notes include minimum interest tests and a maximum leverage ratio. The agreements also restrict the amount of additional indebtedness we may incur and the amount of assets which may be sold. We were in compliance with all our covenant requirements on March 26, 2022.
At the end of the first quarter of 2022, we have approximately $445.3 million in total liquidity, consisting of our net cash surplus and remaining availability under our revolving credit facility. As lumber prices normalize and we move beyond our peak selling season we anticipate the increase in net working capital will turn into strong operating cash flow in the third and fourth quarters.
