We maintain an agreement with a clearing organization that enables us to net securities purchased under resale agreements and sold under repurchase agreements with counterparties that are also members of the clearing organization when specific netting criteria are met. As a result of this netting, the average balances of securities purchased under resale agreements and securities sold under repurchase agreements were reduced by $62.15 billion in 2021 compared to the $100.45 billion reduction in 2020. The decrease in average balance sheet netting, in 2021 compared to 2020, is primarily due to lower FICC repo volumes and lower short-term interest rates.

State Street Bank currently maintains a line of credit of CAD 1.40 billion, or approximately $1.11 billion, as of December 31, 2021, to support its Canadian securities processing operations. The line of credit has no stated termination date and is cancellable by either party with prior notice. As of December 31, 2021 and 2020, there was no balance outstanding on this line of credit.
