Collateralized Transactions

Collateralized transactions

5. Collateralized transactions:

Nomura enters into collateralized transactions, including reverse repurchase agreements, repurchase agreements, securities borrowing transactions, securities lending transactions, other secured borrowings and similar transactions mainly to meet clients’ financing needs, finance trading inventory positions and obtain securities for settlement.

Reverse repurchase agreements, repurchase agreements, securities borrowing transactions and securities lending transactions are typically documented under industry standard master netting agreements which mitigate Nomura’s credit exposure to counterparties. For certain centrally-cleared reverse repurchase and repurchase agreements, the clearing or membership agreements entered into by Nomura provide similar rights to Nomura in the event of default of the relevant central clearing counterparty. Nomura generally seeks to obtain an external legal opinion in order to ascertain the enforceability of such close-out and offsetting rights within these agreements.

Nomura may enter into reverse repurchase agreements, repurchase agreements, securities borrowing and securities lending transactions with certain types of counterparties and in certain jurisdictions which are not documented under a master netting agreement. Even when these transactions are documented under such master netting agreements, Nomura may not have obtained, or may not be able to obtain, evidence to determine with sufficient certainty that the close-out and offsetting rights in the agreements are legally enforceable. This may be the case where relevant local laws explicitly prohibit such close-out and offsetting rights, or where local laws are complex, ambiguous or silent on the enforceability of such rights. This may include reverse repurchase agreements, repurchase agreements, securities borrowing and securities lending transactions executed with certain foreign governments, agencies, municipalities, central clearing counterparties, agent banks and pension funds.

Nomura considers the enforceability of a master netting agreement in determining how credit risk arising from transactions with a specific counterparty is hedged, how counterparty credit exposures are calculated and applied to credit limits and the extent and nature of collateral requirements from the counterparty.

In all of these transactions, Nomura either receives or provides collateral, including Japanese and non-Japanese government, agency, mortgage-backed, bank and corporate debt securities and equities. In most cases, the party receiving the collateral is free to sell or repledge the securities received through repurchase agreements, securities lending transactions or to cover short positions. In repurchase and reverse repurchase agreements, the value of collateral typically exceeds the amount of cash transferred, where collateral is generally in the form of securities. Securities borrowing transactions generally require Nomura to provide the counterparty with collateral in the form of cash or other securities. For securities lending transactions, Nomura generally receives collateral in the form of cash or other securities. Nomura monitors the market value of the securities either received from or provided to the counterparty. Additional cash or securities are exchanged as necessary, to ensure that such transactions are adequately collateralized throughout the life of the transactions.

Offsetting of certain collateralized transactions

Reverse repurchase agreements and repurchase agreements, securities borrowing and lending transactions with the same counterparty documented under a master netting agreement are offset in the consolidated balance sheets where specific criteria as defined by ASC 210-20 are met. These criteria include requirements around maturity of transactions, underlying systems on which collateral is settled, associated banking arrangements and legal enforceability of close-out and offsetting rights under relevant master netting agreements.

The following tables present information about offsetting of these transactions in the consolidated balance sheets as of March 31, 2025 and September 30, 2025, together with the extent to which master netting agreements entered into with counterparties and central clearing parties permit additional offsetting in the event of counterparty default. Transactions which are not documented under a master netting agreement or are documented under a master netting agreement for which Nomura does not have sufficient evidence of enforceability are not offset in the following tables.
