Introduction
• Historically, central banks played active role in lending directions
• Since 1980s, banks given less prescriptive credit direction
• Systemic stability encouraged by setting capital requirements for different lending activities
• APRA regulates capital adequacy
![Page 6: Credit Management Chap 12](https://reader033.vdocument.in/reader033/viewer/2022061120/546c0b41af795971298b4de9/html5/thumbnails/6.jpg)
Capital Adequacy
• Recent evidence shows poor credit decisions play a major part in bank failures
• Generally, banks required to allocate a minimum of 8% of a loan’s value from Capital
• As some loans riskier than others, risk weighting system adopted
![Page 7: Credit Management Chap 12](https://reader033.vdocument.in/reader033/viewer/2022061120/546c0b41af795971298b4de9/html5/thumbnails/7.jpg)
Capital Adequacy
– Capital defined in two broad terms• Tier 1: Capital of a permanent nature such
as shareholder’s equity, general reserves, retained earnings etc
• Tier 2: Capital of a less permanent nature such as provisions for doubtful debts, asset revaluation reserves, convertible notes etc.
• At least 50% of capital must be Tier 1
![Page 8: Credit Management Chap 12](https://reader033.vdocument.in/reader033/viewer/2022061120/546c0b41af795971298b4de9/html5/thumbnails/8.jpg)
Capital Adequacy
– To allow for different risk profiles, risk-weighted capital placed into four categories
• Category 1 (0% Weight): notes and coins, balances with RBA, Commonwealth Government securities less than 12 months to maturity
• Category 2 (10% Weight): Commonwealth Government securities greater than 12 months to maturity, claims on semi government authorities
![Page 9: Credit Management Chap 12](https://reader033.vdocument.in/reader033/viewer/2022061120/546c0b41af795971298b4de9/html5/thumbnails/9.jpg)
Capital Adequacy
• Category 3 (20% Weight): Claims on other banks
• Category 4 has two components:– 50% Weight: Loans fully secured by residential
mortgages with LVR of 80% or less;– 100% Weight: Loans fully secured by residential
mortgages with LVR greater than 80%
• Risk-based capital ratio is then:
Assets Adjusted-Risk
2)Tier 1(Tier Capital Total ratio capital based-Risk
![Page 10: Credit Management Chap 12](https://reader033.vdocument.in/reader033/viewer/2022061120/546c0b41af795971298b4de9/html5/thumbnails/10.jpg)
Capital Adequacy
• Capital Adequacy Example: Assume a bank has the following loan assets• Housing Loans
Risk-Weighted Asset = Notional Amt x Risk Weighting
= $75m x 50%
= $37.5m
• Commercial LoansRisk-Weighted Asset = Notional Amt x Risk Weighting
= $20m x 100%
= $20m
![Page 11: Credit Management Chap 12](https://reader033.vdocument.in/reader033/viewer/2022061120/546c0b41af795971298b4de9/html5/thumbnails/11.jpg)
Capital Adequacy
• If the bank currently has total capital of $15m to support the loan assets, the banks risk based capital ratio is then:
%1.26 ratio capital based-Risk$37.5m $20m
m15$ ratio capital based-Risk
Assets Adjusted-Risk
2)Tier 1(Tier Capital Total ratio capital based-Risk
• While this approach is a useful approximation, it fails to discriminate between AAA-rated and D-rated (ie companies in default) corporates.

Large Credit Exposures
– APRA governs approved deposit-taking institutions (ADIs) and the risks of large credit exposures defined in Prudential Standard APS 221 such as:
• Individual counterparties; or• Groups of related counterparties
– For the purposes of APS 221, a large exposure must not exceed 10% of the bank’s consolidated capital base.
![Page 13: Credit Management Chap 12](https://reader033.vdocument.in/reader033/viewer/2022061120/546c0b41af795971298b4de9/html5/thumbnails/13.jpg)
Securitisation
– As securitisation has the capacity to remove loan assets from the Statement of financial position, APRA has released APS 120 and Guidance Note AGN 120.3 concerning clean sales which:
• Absolves the institution from any legal recourse from the sale of loans;
• Results in the financial institution not holding capital against the loan
![Page 14: Credit Management Chap 12](https://reader033.vdocument.in/reader033/viewer/2022061120/546c0b41af795971298b4de9/html5/thumbnails/14.jpg)
Securitisation
• Clean sale supply of assets:
– Should be no beneficial interest in the sold assets and absolutely no obligation on institution
– Should be no recourse (including costs) to the institution and no obligation to repurchase loan asset
![Page 15: Credit Management Chap 12](https://reader033.vdocument.in/reader033/viewer/2022061120/546c0b41af795971298b4de9/html5/thumbnails/15.jpg)
Securitisation
– Amount paid for loans should be fixed and received at time asset is transferred from lending institution
– Any assets provided to the Special Purpose Vehicle (SPV) as a substitute or sold below book value do not relieve credit risk
![Page 16: Credit Management Chap 12](https://reader033.vdocument.in/reader033/viewer/2022061120/546c0b41af795971298b4de9/html5/thumbnails/16.jpg)
Securitisation
• Revolving Facilities: – Defined as assets with ongoing credit
relationship such as credit cards and home loans
– Rights, details of cashflows and obligations of each party must be clearly specified
– As with normal securitisation, institution cannot supply additional assets to the pool
![Page 17: Credit Management Chap 12](https://reader033.vdocument.in/reader033/viewer/2022061120/546c0b41af795971298b4de9/html5/thumbnails/17.jpg)
Securitisation
– Liquidity shortfalls for the institution share must not exceed the interest receivable
– Institution retains right to cancel undrawn amounts
– Institution must have no obligation to repurchase
![Page 18: Credit Management Chap 12](https://reader033.vdocument.in/reader033/viewer/2022061120/546c0b41af795971298b4de9/html5/thumbnails/18.jpg)
Credit Derivatives
– As credit derivatives are relatively new, APRA has adopted a conservative stance through AGN 112.4
– Product must not be overly restrictive and must allow sufficient risk transfer
– Any mismatches between exposures and risk protected by the product, eg maturity mismatch, will reduce effectiveness of capital charge reduction
![Page 19: Credit Management Chap 12](https://reader033.vdocument.in/reader033/viewer/2022061120/546c0b41af795971298b4de9/html5/thumbnails/19.jpg)
Developments in Regulation
– The first Basel Accord on capital standards (known as Basel I) treated all corporate loan risk the same
– Clearly inadequate for capital charges to be identical for corporations of varying credit quality
– The new proposed accord, known as Basel II addresses this by incorporating published credit ratings information
![Page 20: Credit Management Chap 12](https://reader033.vdocument.in/reader033/viewer/2022061120/546c0b41af795971298b4de9/html5/thumbnails/20.jpg)
Credit Ratings
– These are provided by many companies including S&P, Moody’s, Fitch’s etc
– Generally fall into two types, short and long-term and S&P ratings are:
Long Term Short Term
AAA BBB CCC A-1 B
AA BB CC A-2 C
A B C & D A-3 D
![Page 21: Credit Management Chap 12](https://reader033.vdocument.in/reader033/viewer/2022061120/546c0b41af795971298b4de9/html5/thumbnails/21.jpg)
Credit Ratings
• Ratings Criteria– Business Risks examined include:
• Industry Characteristics: Considered according to profitability, diversification factors, size, geographic and market dominance
• Management Evaluation: Management’s ability to create and follow plan and any excessive reliance on one person
• Industry-Specific Factors: Regulations, markets, operations and competitiveness
![Page 22: Credit Management Chap 12](https://reader033.vdocument.in/reader033/viewer/2022061120/546c0b41af795971298b4de9/html5/thumbnails/22.jpg)
Credit Ratings
• Financial Risk– Accounting Quality: Are accounting standards
and controls of sufficient quality– Financial Policy: Does the firm have a financial
policy and how are risks treated– Profitability and Coverage: Factors include pre-
tax interest return on capital, operating income as percentage of sales and earnings on business segment’s assets. Also considers trends, reconciling historical trends with projected earnings and earnings in relation to fixed charges.

Credit Ratings
– Capital Structure/Leverage and Asset Protection: Considers following ratios:
» Total Debt / (Total Debt + Equity)» (Total Debt + Off-Balance-Sheet Liabilities) /
(Total Debt + Off-Balance-Sheet Liabilities + Equity)
» Total Debt / (Total Debt + Market Value of Equities)
– Asset Valuation: How do asset valuations affect key ratios and viability
![Page 24: Credit Management Chap 12](https://reader033.vdocument.in/reader033/viewer/2022061120/546c0b41af795971298b4de9/html5/thumbnails/24.jpg)
Credit Ratings
– Off-Statement of Financial Position Financing: Techniques that may affect leverage include:
» Operating Leases» Debt of joint ventures and unconsolidated
subsidiary’s guarantees» Take or pay contracts and obligations under
throughput and deficiency agreements» Receivables that have been factored,
transferred and securitised» Contingent liabilities
– Preferred Stock: Cashflow characteristics of Preference shares issued by the firm
![Page 25: Credit Management Chap 12](https://reader033.vdocument.in/reader033/viewer/2022061120/546c0b41af795971298b4de9/html5/thumbnails/25.jpg)
Credit Ratings
– Cashflow Adequacy and Ratios: As cashflow, and not accounting earnings, repays debt the following ratios are considered:
» Funds from Operations / Total Debt» EBITDA / Interest» (Free Operating Cashflow + Interest) / (Interest +
annual principal repayment obligations)» Total debt / Discretionary Cashflow» Funds from Operations / Capital Spending
Requirements » Capital Expenditure / Capital Maintenance

Credit Ratings
– The Need for Capital: Considers business requirements for equity and working capital relative to capital works needs
– Financial Flexibility: does the firm have excessive reliance on one capital source
• This list is not exhaustive, but does cover some of the main areas considered by S&P
• Exactly how all of the above ingredients are put together and the weightings of each element remains a commercial secret

Basel II
– The Bank for International Settlements (BIS) is currently evaluating the new capital proposals
– Banks can use two approaches to capital allocation, internal and external. Internal approach must possess:Objectivity International Access
Independence Resources
Transparency Recognition (BIS)
