Case study - 2 : Calculation of Capital Fund (Non-Fund based)
Calculation of Capital Fund (Non-Fund based)

Universal Bank has allowed non-fund based credit facilities to its borrowers, the details of which are as under:
a) letters of credit for imports of goods and buying of domestic goods to various parties within the retail portfolio — Rs.1000 cr (out of this, to AAA rated companies 20% and the balance for BBB rated).
b) standby letters of credit serving as financial guarantees for credit enhancements — Rs.500 cr (Entire amount is to A rated companies)
c) Standby letters of credit related to particular transactions — Rs.200 cr (out of this to AA rated is 50% and balance amount is for unrated companies).
d) Performance bonds and bid bonds on behalf of their customers Rs.1000 cr (out of this 50% is to A rated and the balance for unrated
e) Financial guarantees—Rs.400 cr (on behalf of AA rated companies)
f) Letters of credit of other banks confirmed by Universal Bank for imports — Rs.100 cr

RBI guidelines on credit conversion factor (CCF) are as under:
1. Direct credit substitutes e.g. general guarantees of indebtedness(including standby L/Cs serving as financial guarantees for loans and
securities, credit enhancements, liquidity facilities for securitisation transactions), and acceptances (including endorsements with the
character of acceptance). (i.e., the risk of loss depends on the credit worthiness of the counterparty or the party against whom a potential
claim is acquired) : 100%
2. Certain transaction-related contingent items (e.g. performance bonds, bid bonds, warranties, indemnities, standby LC related to particular transaction) : 50%
3. Short-term self-liquidating trade letters of credit arising from the movement of goods (e.g. documentary credits collateralised by the
underlying shipment) for both issuing bank and confirming bank : 20% The rules relating to risk weight for corporates based on rating provide
as under:AAA rated — 20%, AA-30%, A-50%, BBB-100%, BB & Below-150%, unrated- 100%

Please calculate the total amount of risk weighted assets and the total capital fund requirement.
Solution: To calculate the risk weight and provide for capital, the non-fund based exposure will be first converted into the funded exposure by
applying the credit conversion factor.
Calculation of credit exposure using CCF:
a) Rs.1000 cr x 20% = 200 cr.
b) Rs.500 cr x 100% = 500 cr
c) Rs.200 cr x 50% = 100 cr
d) Rs.1000 cr x 50% = 500 cr
e) Rs.400 cr x 100% = 400 cr t) Rs.100 cr x 20% = 20 cr

Calculation of Risk weight on the above credit exposure:
a) Rs. 200 crOut of this for 20% i.e. Rs.40 cr x 20% = 8 cr (20% is for AAA rated companies where risk weight is 20%)
Out of this for 80% i.e. Rs.160 cr x 100% = 160 cr (for this the risk weight is 100%)
b) Rs.500 cr x 50% = 250 cr (for A rated companies, the risk weight is 50%)
c) Rs.100 crOut of this for 50% i.e. Rs.50 cr x 30% = 15 cr (risk weight is 30% for AA rated companies)
Out of this for 50% i.e. Rs.50 cr x 100 = 50 cr (risk weight is 100% for unrated companies)
d) Rs.500 crOut of this for 50% i.e. Rs.250 cr x 50% = 125 cr (risk weight is 50% for A rated companies)
Out of this for 50% i.e. Rs.250 cr x 100% = 250 cr (risk weight is 100% for unrated companies)
e) Rs.400 cr x 30% = 120 cr (risk weight is 30% for AA ratedcompanies)
f) 20 cr x 20% = 4 cr (risk weight for confirming banks is 20%).
Total amount of risk weight assets from (a) to. (f)
8+ 160 + 250 + 15 + 50 + 125 + 250 + 120 4= 982
Minimum capital fund required for risk weighted assets of Rs.982 cr = 982 x 9% = Rs.88.38 cr
