Section 50.21 - High-quality liquid asset amount(a)Calculation of the HQLA amount. As of the calculation date, a national bank's or Federal savings association's HQLA amount equals: (1) The level 1 liquid asset amount; plus(2) The level 2A liquid asset amount; plus(3) The level 2B liquid asset amount; minus(4) The greater of:(i) The unadjusted excess HQLA amount; and(ii) The adjusted excess HQLA amount.(b)Calculation of liquid asset amounts - (1)Level 1 liquid asset amount. The level 1 liquid asset amount equals the fair value of all level 1 liquid assets held by the national bank or Federal savings association as of the calculation date that are eligible HQLA, less the amount of the reserve balance requirement under section 204.5 of Regulation D (12 CFR 204.5 ) .(2)Level 2A liquid asset amount. The level 2A liquid asset amount equals 85 percent of the fair value of all level 2A liquid assets held by the national bank or Federal savings association as of the calculation date that are eligible HQLA.(3)Level 2B liquid asset amount. The level 2B liquid asset amount equals 50 percent of the fair value of all level 2B liquid assets held by the national bank or Federal savings association as of the calculation date that are eligible HQLA.(c)Calculation of the unadjusted excess HQLA amount. As of the calculation date, the unadjusted excess HQLA amount equals: (1) The level 2 cap excess amount; plus(2) The level 2B cap excess amount.(d)Calculation of the level 2 cap excess amount. As of the calculation date, the level 2 cap excess amount equals the greater of: (1) The level 2A liquid asset amount plus the level 2B liquid asset amount minus 0.6667 times the level 1 liquid asset amount; and(e)Calculation of the level 2B cap excess amount. As of the calculation date, the level 2B excess amount equals the greater of: (1) The level 2B liquid asset amount minus the level 2 cap excess amount minus 0.1765 times the sum of the level 1 liquid asset amount and the level 2A liquid asset amount; and(f)Calculation of adjusted liquid asset amounts -(1)Adjusted level 1 liquid asset amount. A national bank's or Federal savings association's adjusted level 1 liquid asset amount equals the fair value of all level 1 liquid assets that would be eligible HQLA and would be held by the national bank or Federal savings association upon the unwind of any secured funding transaction (other than a collateralized deposit), secured lending transaction, asset exchange, or collateralized derivatives transaction that matures within 30 calendar days of the calculation date where the national bank or Federal savings association will provide an asset that is eligible HQLA and the counterparty will provide an asset that will be eligible HQLA; less the amount of the reserve balance requirement under section 204.5 of Regulation D (12 CFR 204.5 ) .(2)Adjusted level 2A liquid asset amount. A national bank's or Federal savings association's adjusted level 2A liquid asset amount equals 85 percent of the fair value of all level 2A liquid assets that would be eligible HQLA and would be held by the national bank or Federal savings association upon the unwind of any secured funding transaction (other than a collateralized deposit), secured lending transaction, asset exchange, or collateralized derivatives transaction that matures within 30 calendar days of the calculation date where the national bank or Federal savings association will provide an asset that is eligible HQLA and the counterparty will provide an asset that will be eligible HQLA.(3)Adjusted level 2B liquid asset amount. A national bank's or Federal savings association's adjusted level 2B liquid asset amount equals 50 percent of the fair value of all level 2B liquid assets that would be eligible HQLA and would be held by the national bank or Federal savings association upon the unwind of any secured funding transaction (other than a collateralized deposit), secured lending transaction, asset exchange, or collateralized derivatives transaction that matures within 30 calendar days of the calculation date where the national bank or Federal savings association will provide an asset that is eligible HQLA and the counterparty will provide an asset that will be eligible HQLA.(g)Calculation of the adjusted excess HQLA amount. As of the calculation date, the adjusted excess HQLA amount equals: (1) The adjusted level 2 cap excess amount; plus(2) The adjusted level 2B cap excess amount.(h)Calculation of the adjusted level 2 cap excess amount. As of the calculation date, the adjusted level 2 cap excess amount equals the greater of:(1) The adjusted level 2A liquid asset amount plus the adjusted level 2B liquid asset amount minus 0.6667 times the adjusted level 1 liquid asset amount; and(i)Calculation of the adjusted level 2B excess amount. As of the calculation date, the adjusted level 2B excess liquid asset amount equals the greater of: (1) The adjusted level 2B liquid asset amount minus the adjusted level 2 cap excess amount minus 0.1765 times the sum of the adjusted level 1 liquid asset amount and the adjusted level 2A liquid asset amount; and
