(3)Indian toll roads include our investments in BIF India Holdings Pte Ltd

(4)Our partnership’s cash from operating activities include reduction to cash related to the impact of our finance lease receivables signed at our North American residential decarbonization infrastructure business. 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 offset by increases in non-recourse borrowings under financing activities on the Consolidated Statements of Cash Flows.
