Which among the following is NOT a constituent of  Tier-II capital of banks according to BASEL Accord?

Tier 2 capital must be at least 2% of RWAs on an ongoing basis. Tier 2 Capital: represents “supplementary capital” such as undisclosed reserves, revaluation reserves, general loan-loss reserves, hybrid (debt/equity) capital instruments, and subordinated debt of the financial institution. Tier 2 Capital is generally less reliable or secure than Tier 1 capital, and therefore must be considered separately when evaluating the riskiness of a bank. Capital reserve is a disclosed reserve and forms a part of the Tier I capital of the bank.
