Capital Funds
Equity contribution of owners. The basic approach of capital adequacy framework is that a bank should have sufficient capital to provide a stable resource to absorb any losses arising from the risks in its business. Capital is divided into different tiers according to the characteristics / qualities of each qualifying instrument. For supervisory purposes capital is split into two categories: Tier I and Tier II.
Tier I Capital
A term used to refer to one of the components of regulatory capital. It consists mainly of share capital and disclosed reserves (minus goodwill, if any). Tier I items are deemed to be of the highest quality because they are fully available to cover losses Hence it is also termed as core capital.
Tier II Capital
Refers to one of the components of regulatory capital. Also known as supplementary capital, it consists of certain reserves and certain types of subordinated debt. Tier II items qualify as regulatory capital to the extent that they can be used to absorb losses arising from a bank's activities. Tier II's capital loss absorption capacity is lower than that of Tier I capital.
Revaluation reserves
Revaluation reserves are a part of Tier-II capital. These reserves arise from revaluation of assets that are undervalued on the bank's books, typically bank premises and marketable securities. The extent to which the revaluation reserves can be relied upon as a cushion for unexpected losses depends mainly upon the level of certainty that can be placed on estimates of the market values of the relevant assets and the subsequent deterioration in values under difficult market conditions or in a forced sale.
Ratio of assets to capital.
Capital reserves
That portion of a company's profits not paid out as dividends to shareholders. They are also known as undistributable reserves and are ploughed back into the business.
Deferred Tax Assets
Unabsorbed depreciation and carry forward of losses which can be set-off against future taxable income which is considered as timing differences result in deferred tax assets. The deferred Tax Assets are accounted as per the Accounting Standard 22.
Deferred Tax Liabilities
Deferred tax liabilities have an effect of increasing future year's income tax payments, which indicates that they are accrued income taxes and meet definition of liabilities.
Subordinated debt
Refers to the status of the debt. In the event of the bankruptcy or liquidation of the debtor, subordinated debt only has a secondary claim on repayments, after other debt has been repaid.
Hybrid debt capital instruments
In this category, fall a number of capital instruments, which combine certain characteristics of equity and certain characteristics of debt. Each has a particular feature, which can be considered to affect its quality as capital. Where these instruments have close similarities to equity, in particular when they are able to support losses on an ongoing basis without triggering liquidation, they may be included in Tier II capital.
BASEL Committee on Banking Supervision
The BASEL Committee is a committee of bank supervisors consisting of members from each of the G10 countries. The Committee is a forum for discussion on the handling of specific supervisory problems. It coordinates the sharing of supervisory responsibilities among national authorities in respect of banks' foreign establishments with the aim of ensuring effective supervision of banks' activities worldwide.
BASEL Capital accord
The BASEL Capital Accord is an Agreement concluded among country representatives in 1988 to develop standardised risk-based capital requirements for banks across countries. The Accord was replaced with a new capital adequacy framework (BASEL II), published in June 2004. BASEL II is based on three mutually reinforcing pillars hat allow banks and supervisors to evaluate properly the various risks that banks face. These three pillars are:
 Minimum capital requirements, which seek to refine the present measurement framework
 supervisory review of an institution's capital adequacy and internal assessment process;
 market discipline through effective disclosure to encourage safe and sound banking practices
Risk Weighted Asset
The notional amount of the asset is multiplied by the risk weight assigned to the asset to arrive at the risk weighted asset number. Risk weight for different assets vary e.g. 0% on a Government Dated Security and 20% on a AAA rated foreign bank etc.
CRAR(Capital to Risk Weighted Assets Ratio)
Capital to risk weighted assets ratio is arrived at by dividing the capital of the bank with aggregated risk weighted assets for credit risk, market risk and operational risk. The higher the CRAR of a bank the better capitalized it is.
Credit Risk
The risk that a party to a contractual agreement or transaction will be unable to meet its obligations or will default on commitments. Credit risk can be associated with almost any financial transaction. BASEL-II provides two options for measurement of capital charge for credit risk
1.standardised approach (SA) - Under the SA, the banks use a risk-weighting schedule for measuring the credit risk of its assets by assigning risk weights based on the rating assigned by the external credit rating agencies.
2. Internal rating based approach (IRB) - The IRB approach, on the other hand, allows banks to use their own internal ratings of counterparties and exposures, which permit a finer differentiation of risk for various exposures and hence delivers capital requirements that are better aligned to the degree of risks. The IRB approaches are of two types:
a) Foundation IRB (FIRB): The bank estimates the Probability of Default (PD) associated with each borrower, and the supervisor supplies other inputs such as Loss Given Default (LGD) and Exposure At Default (EAD).
b) Advanced IRB (AIRB): In addition to Probability of Default (PD), the bank estimates other inputs such as EAD and LGD. The requirements for this approach are more exacting. The adoption of advanced approaches would require the banks to meet minimum requirements relating to internal ratings at the outset and on an ongoing basis such as those relating to the design of the rating system, operations, controls, corporate governance, and estimation and validation of credit risk components, viz., PD for both FIRB and AIRB and LGD and EAD for AIRB. The banks should have, at the minimum, PD data for five years and LGD and EAD data for seven years. In India, banks have been advised to compute capital requirements for credit risk adopting the SA.
Market risk
Market risk is defined as the risk of loss arising from movements in market prices or rates away from the rates or prices set out in a transaction or agreement. The capital charge for market risk was introduced by the BASEL Committee on Banking Supervision through the Market Risk Amendment of January 1996 to the capital accord of 1988 (BASEL I Framework). There are two methodologies available to estimate the capital requirement to cover market risks:
1) The Standardised Measurement Method: This method, currently implemented by the Reserve Bank, adopts a ‘building block’ approach for interest-rate related and equity instruments which differentiate capital requirements for ‘specific risk’ from those of ‘general market risk’. The ‘specific risk charge’ is designed to protect against an adverse movement in the price of an individual security due to factors related to the individual issuer. The ‘general market risk charge’ is designed to protect against the interest rate risk in the portfolio.
2) The Internal Models Approach (IMA): This method enables banks to use their proprietary in-house method which must meet the qualitative and quantitative criteria set out by the BCBS and is subject to the explicit approval of the supervisory authority.
Operational Risk
The revised BASEL II framework offers the following three approaches for estimating capital charges for operational risk:
1) The Basic Indicator Approach (BIA): This approach sets a charge for operational risk as a fixed percentage ("alpha factor") of a single indicator, which serves as a proxy for the bank’s risk exposure.
2) The Standardised Approach (SA): This approach requires that the institution separate its operations into eight standard business lines, and the capital charge for each business line is calculated by multiplying gross income of that business line by a factor (denoted beta) assigned to that business line.
3) Advanced Measurement Approach (AMA): Under this approach, the regulatory capital requirement will equal the risk measure generated by the banks’ internal operational risk measurement system. In India, the banks have been advised to adopt the BIA to estimate the capital charge for operational risk and 15% of average gross income of last three years is taken for calculating capital charge for operational risk.
