Certificate validity and renewal: custodian registration, updated fee regime, asset-based annual fee and safekeeping conditions. Amendments set a uniform multi-year validity for custodian certificates and require renewal applications to be filed before expiry and treated as fresh applications with applicable fees. The fee regime is revised to specify application, registration and an annual fee, the latter payable after each financial year and calculated as the higher of a fixed sum or an asset-linked charge based on assets under custody; payment must include a certified statement of assets. Custodians may subcontract physical safekeeping of gold for mutual fund gold ETF schemes, while retaining full responsibility and record-keeping obligations.
