•
Any additional perpetual preferred stock not allowed
in Tier 1
Subordinated notes and debentures (up to 50
percent of Tier 2 capital)
Allowance for loan and lease losses (up to 1.25% of
risk-weighted assets)
Mandatory convertible subordinated debt

Definitions of Capital Adequacy
Regulatory Capital Ratios (minimum)
•
•
•
Tier 1 capital/Total assets ratio = 4%
Tier 1 capital/Total risk-based assets ratio = 4%
Tier 1 + Tier 2 capital/total risk-based assets ratio = 8%

Credit risk overall
Riskiness of various assets
Basel I does not take into account
•
•
•
•

Operating risk
Credit risk variance between different loans

Table 6.3 Calculating a Risk-Based
Capital Ratio for Mega Bank
6-13
Capital standards are based in part on the riskiness of an institution's assets and on the degree of its
off-balance-sheet involvement. Depositories with lower-risk assets and lower-risk off-balance-sheet
activities will have more favorable capital ratios than higher-risk institutions.

Minimum Capital Requirements
Minimum capital required for a $100 million commercial loan of quality
AAA
Pre-1982 All judgemental by Regulators
Basel I (Current Rules)
$8
Basel II Advanced IRB
$0.37 to $4.45
BBB-
B
$8
$1.01 to $14.13
$8
$3.97 to $41.65
Notes: The quality of loans refers to one-year default probabilities corresponding to the historical average for a
given credit rating, in this case an unsecured credit with an assumed loss given a default (LGD) of 45 percent.
The one-year probability of default used is 0.03 percent for AAA, 0.35 percent for BBB, 8.38 percent for B,
based on a maturity of 2.5 years. Lower bounds reflect an LGD of 10 percent for high recovery for a one-year
loan and 90percent for a five-year loan. All Basel II capital calculations (standardized and IRB) include an
operational risk charge (under the Basic Indicator Approach, the operational capital charge is equal to 15
percent of the institution's average gross income over the previous three years). As a proxy for gross income,
the calculations in this table use dthe current industry average ROA (1.41% X the amount of the loan, $100)
for an estimated operational risk charge of $0.21 (15 percent of $1.41).
