Bank Ratings Methodology
Rating Analysis Methodology Profile
Credit analysis of a bank includes
a wide range of quantifiable and nonquantifiable factors. The weight
given each in the analysis of a particular institution will vary,
depending on its competitive position within its specific sector,
the characteristics and the risk profile of the sector itself, and
the overall regulatory environment. Thus, there is no standard group
of ratios that set minimum requirements for each rating category.
Taiwan Ratings Corporation (TRC) takes the following key areas into
consideration when rating a bank:
INDUSTRY RISK
The industry risk category contains
many elements, and for each type of financial institution there
will be both positive and negative factors. While it is difficult
to say which factors will outweigh others in any one category, generally
Taiwan Ratings Corporation gauges the dynamics of the financial
services industry and to what extent those dynamics lead to more
or less risk from the debtholder's or counterparty's point of view.
Following is a list of considerations for the industry risk category.
Structure.
- The basic structure of the banking
system, which includes the number and relative sizes of institutions
and restrictions on geographic or product expansion;
- Proportion of finance in the economy
that is intermediated through the banks; nonbank competitors in
the market and the extent to which they pose a serious challenge
to the banks in their role as intermediary in the economy;
- Depth of publicly traded capital
markets and the trends in this area;
- Dynamics of interindustry and intraindustry
competition, barriers to entry, expectation of change, and degree
of disintermediation in industry;
- Consolidation trends in banking
system, the number of banks and branches in relation to the population,
and impediments such as labor laws that negatively impact the
banks' ability to reduce overheads;
- Strategic stakes in industrial companies
and types of benefits and risks posed by these holdings;
- Extent to which political or other
interests are able to influence the decisionmaking process at
the bank;
- Quality and transparency of accounting
and reporting systems and the quality of external auditing; and
- Strength and efficiency of country's
legal system
Ownership structure of banks
- Degree of
government ownership within the banking system, the extent to
which government involvement in the system affects the competitive
dynamics in the banking market; and
- Degree of
ownership of banks by corporate or individuals and advantages
and disadvantages of or dangers stemming from these relationships.
Market
position and diversification
Market position:
Focuses on the evaluation of benefits or weakness stemming from
institution's market position.
- Bank's market shares in key businesses and the size of these
markets;
- Real advantages stemming from bank's market position (e.g.
pricing power, funding base, quality of business etc.); and
- Vulnerability of market position.
Diversification:
- Analysis
of diversity of a bank's business and benefits stemming from it;
identification of any geographic or business concentrations;
- Diversity
of products/business lines/customer base;
- Geographical
spread of bank's business base;
- Economic
diversity of bank's home market(s); and
- International
diversification: size and extent to which this adds real franchise
value.
Credit Risk
Looks at an institution's credit risk across the entire spectrum
of the institution's activities (including loans, debt securities,
equity investments, on- and off- balance-sheet counterparty exposure
etc.)
- Structure
of balance sheet, including relative proportion in different low
credit risk assets (e.g. government bills or interbank deposits)
compared with higher risk assets (e.g. loans or equities);
- Fixed-income
securities (breakdown by type, largest positions, and market value
and maturity structure);
- Equity securities
(breakdown by economic sector, largest exposures, proportion of
investment portfolio relating to previous underwriting positions,
investment strategy, book value compared with market value);
- Credit portfolio
broken down by maturity, loan type, collateral, customer base,
economic sector, size, currency, and country;
- Concentrations
of credit risk, such as large exposures to specific industries,
markets, and individual borrowers, or in specific loan types;
- Problem
loans: large problem-credit exposures, levels in and changes of
nonperforming assets, past-due loans, restructured loans, and
other problem-asset categories and expected future trends;
- Loan loss
reserves, broken down by type, such as general and specific, reserves
against on- and off-balance sheet exposures, taxed and untaxed;
- Reconciliation
of each type of loan loss reserve over the past five years, showing
new provisions, liquidations of provisions, charge-offs, and recoveries;
and
- Reserving
policy and adequacy
Market Risk
Level of market risk over the entire range of financial institution's
activities, whether on- or off-balance sheet, e.g., in its asset
and liability structure, trading activities, securities underwriting
business, etc. Management's strategy and general risk appetite in
these areas.
Structural
risks
- Management's
philosophy regarding asset and liability management and balance-sheet
structure;
- Levels of
interest rate, foreign exchange, equity risks in the balance sheet;
- Role of
the treasury department and objectives and risk appetite;
- Reasons
for structural risk: legal restrictions, regulatory requirements,
limitations of local funding or hedging markets, or position taking;
- Use of non-cash
market instruments, such as futures, forwards, and swaps; and
- Past and
future position taking and balance sheet flexibility.
Trading risk
- Description
of current organization
- Trading
strategy on group basis and by individual products
- Review of
historic trading activities by products and market, including
size of positions, volatility of net revenues, and profitability.
Proportion of revenues from sales, jobbing, arbitrage, and directional
view. Liquidity of markets in which the banks deals;
- Perceived
market strengths and weaknesses; market position and appetite
for position taking;
- Future products
and market expansion plans; and
- Breakdown
of products by currency, credit quality, volume and maturity.
Funding and
Liquidity
Represent
the evaluation of the bank's sources of funds and factors influencing
its liquidity position.
- Composition
of the bank's funding (core retail compared with other retail,
semi-professional, and professional markets);
- Diversity
of funding sources, such as deposits broken down by geography
and size, access to and importance in local and national capital
and money markets;
- Flow of
funds (net deposit flows, deposit maturates, stability of funding);
- Asset liquidity,
which includes short-term deposits and securities, long-term marketable
securities, extent of pledged assets, ability to sell or securitize
loans, liquidity facilities at the central bank, and other sources
of asset liquidity;
- Management's
philosophy with regard to liquidity as well as liquidity planning.
Capitalization
Analytical emphasis is on capital that provides a cushion for
the bank on a going-concern basis. Thus, Taiwan Ratings Corporation's
perception of a bank's capital position may differ from that of
a regulator, which accepts, as capital, instruments that provide
a cushion for depositors only in the case of liquidation. Regulatory
capital remains an important measure, however, as it influences
the actions of bank management and the regulators.
- Capital
composition. Quality of capital: levels of common equity, preferred
stock, convertibles, subordinate debt, perpetual debt, minority
interests, goodwill and other intangibles, revalued assets, unrealized
capital gains, loan loss reserves in excess of probable losses,
and other types of quasi-equity. If a holding company structure
is involved, level of double leverage;
- Comparison
of capital with perceived level of risk in institution's business:
Bank for International Settlements (BIS) risk-weighted assets
adjusted for high credit risk assets (e.g. equities or specific
types of lending) or market-risk activities;
- Bank's capital
position with respect to domestic capital requirements and the
requirements of the BIS;
- Dividend
layout ratio, internal growth rate of capital
- Absolute
size of bank's capital base and its ability to absorb extraordinary,
unexpected losses that could arise, given the bank's business
mix;
- Ability
to tap external sources of capital and long-term funding. Bank's
market capitalization compared with book value; and
- Management's
philosophy regarding risk asset and loan leveraging of its capital
base and capital projections.
Earnings
Key considerations are earnings levels, trends, and stability;
the basic long-term earnings power of the company.
- Net interest
income: margin trends and ability to maintain volume;
- Noninterest
income: diversity and sustainability of other income sources and
growth potential;
- Operating
expenses: level and trend of overhead relative to the company's
business mix and distribution network, degree of automation in
comparison to peers', ability of earnings to meet current and
future needs;
- Loan loss
provision (current level, past volatility, and ability to absorb
future requirements);
- Net operating
income analysis (level and trend);
- Quality
of earnings: Proportion of income recognized as core earnings,
proportion of earnings from trading activities, ability to price
risk into various products, and actual return on the perceived
risk in the book;
- Impact of
extraordinary gains and/or charges;
- Tax position:
management's philosophy toward tax payment position and cushion,
including historical and future use of net operating loss carrybacks
and carryforwards, other strategies that affect tax position;
- Impact of
inflation on earnings, return on equity versus the reporting period's
inflation rate;
- Earnings
outlook, year-to-date budget versus actual, projections for following
year and medium-term plan; and
- Quality
of bank's accounting practices.
Risk Management
Looks
at the bank's systems for managing all types of risk: credit, treasury,
trading, liquidity etc. In these areas, not only are the rules and
guidelines on how risks are to be managed important, but also the
degree to which the rules and guidelines are actually enforced at
all levels.
Credit risk
- Underwriting
criteria, the approval process for different types of products
or customer groups (for example, fixed-income securities, investment
or trading equities, mortgage loans, customer loans, and corporate
loans), delegation of approval authorities down through the organization
and collateral valuation;
- Monitoring
of credit exposure: control at time of loan disbursement, review
function, internal rating system, delegation of responsibility
for identifying potential problem exposures, and the role of the
audit department; and
- Problem
assets: responsibility for follow-up, collections, aggressiveness
with which problem credits are handled, and collateral foreclosure
policies.
Market risk
- Senior management's
understanding of market-risk issues and its involvement in risk
management decisions;
- Membership
of the asset-liability committee (ALCO) or other decision-making
body, reports filed with ALCO, how its decisions interact with
daily risk management, limits set by ALCO for different types
of risks;
- Information
technology: description of software used to monitor structural
and trading risks, adequacy of computer systems in relation to
the current and projected levels of market risk inherent in the
bank's business as well as management's risk appetite;
- Strategy
regarding intentional position-taking, limits, and authorities
required for breaching limits;
- How traders
and desk heads monitor positions and how the system interacts
with the overall risk management system;
- Hedging
strategies;
- Description
of method(s) by which market risk is measured and assumptions
used;
- Stress testing:
frequency and assumptions, flexibility;
- Back office
and operations: organization vis-a-vis the trading floor, valuation
of positions, and disaster recovery;
- Audit function;
- Accounting
policies; and
- Track record
versus intended risk exposure. Major errors over the past five
years in position-taking, hedging, and accounting.
Financial
flexibility
Evaluates
a bank's ability to meet unexpected demands on capital and earnings.
- Ability
to assess various funding markets and raise capital from public
or private sources, generally and in a difficult environment;
- Internal
reserves that could be used to cover unexpected losses;
- Franchise
value of discrete business, assets where the market value is significantly
greater than the book value, ability to sell, likely value in
stressed situations; and
- Likelihood
of support from governmental or private shareholders
