Four Cs of credit

Also written 4 Cs of credit · Four Cs of credit analysis

The workbook's own credit-analysis framework — Capacity, Collateral, Covenants and Capital — used by a portfolio manager to independently assess default risk rather than rely on a rating alone.

In plain language

A credit rating is a useful starting point for judging a bond issuer, but a serious portfolio manager does not stop there. The workbook gives a framework for going deeper: the four Cs.

Each C is a different lens on the same question — can this issuer actually pay what it owes? Looking at capacity, collateral, covenants and capital together builds a fuller picture than any single rating letter can give, and feeds directly into two numbers a manager actually needs: the chance the issuer defaults, and how much would be lost if it did.

How it works

Section 19.3.2 states it directly: in practice, portfolio managers do not entirely depend on credit rating but do their own credit research to evaluate an issuer's financial condition and future prospects. That research revolves around the four Cs: Capacity, Collateral, Covenants and Capital.

The workbook ties this framework to two specific outputs: (a) probability of default and (b) loss given default — the two components a portfolio manager needs to actually price and monitor credit risk in a bond holding, beyond simply reading off a rating agency's letter grade.

A worked example

Illustrative, following the workbook's own four-Cs framework. A portfolio manager evaluates a Rs 5,00,00,000 exposure to a proposed AA-rated NCD issue from a mid-sized NBFC, going beyond the rating itself:

CWhat the manager checksFinding
CapacityCash flow adequacy to service debtInterest coverage ratio of 2.1x — adequate but thinner than peers
CollateralSecurity backing the issueSecured by receivables worth 1.2x the issue size
CovenantsRestrictive terms protecting lendersAsset-cover and leverage covenants present, tested quarterly
CapitalThe issuer's own equity cushionCapital adequacy ratio of 16%, above the regulatory floor

Weighing all four together, the manager estimates a probability of default of around 1.5% over the bond's five-year tenor, and a loss given default of roughly 35% given the receivables collateral — allowing the manager to decide whether the AA rating's implied spread (say, 200 basis points over the G-Sec) adequately compensates for that specific combination of capacity, collateral, covenant strength and capital, rather than accepting the rating agency's letter grade at face value.

Why NISM asks about it

Chapter 19, section 19.3.2 (Credit Analysis), names the four Cs directly and links them to probability of default and loss given default, immediately after the credit yield spread illustration. Expect a question asking the manager to name the four Cs, or one distinguishing this framework's two outputs (probability of default, loss given default).

Common exam traps

  • The workbook's four Cs are Capacity, Collateral, Covenants and Capital — not the widely-taught five-Cs mnemonic, which also includes Character and Conditions. Answer with the workbook's own list of four on this paper.
  • Credit rating and independent credit research are complementary, not substitutes — the workbook explicitly says managers do not rely on the rating alone, not that they ignore it.
  • Probability of default and loss given default are two separate numbers, both needed to price credit risk — a high probability of default with strong collateral (low loss given default) can be less costly than a lower probability of default with weak collateral.
  • This framework sits inside the broader discussion of credit yield spread — the four Cs explain why a spread should be wide or narrow, not a separate, unrelated topic.
