(1)During the year ended December 31, 2021, changes in non-cash working capital include a $0.3 billion, (2020: $0.3 billion, 2019: $nil) reduction to cash related to the impact of finance lease receivables signed at our North American residential energy infrastructure operation. The operation presents an outflow for the cost of inventory within the operating cash flows, and given the business has been securitized since 2019, the corresponding cash outflows are more than offset by increases in non-recourse borrowings under financing activities on the Consolidated Statements of Cash Flows.
