In certain cases, we participate in securities finance transactions as a principal. As a principal, we borrow securities from the lending client and then lend such securities to the subsequent borrower, either our client or a broker/dealer. Our right to receive and obligation to return collateral in connection with our securities lending transactions are recorded in other assets and other liabilities, respectively, in our consolidated statement of condition. As of March 31, 2019 and December 31, 2018, we had approximately $23.93 billion and $19.58 billion, respectively, of collateral provided and approximately $14.01 billion and $11.52 billion, respectively, of collateral received from clients in connection with our participation in principal securities finance transactions.
