Investor losses include lost principal and interest, decreased cash flow, and increased collection costs, which arise in a number of circumstances:
A consumer does not make a payment due on a mortgage loan, credit card, line of credit, or other loan.
A business does not make a payment due on a mortgage, credit card, line of credit, or other loan
A business does not make a payment due on a mortgage, credit card, line of credit, or other loan
A business or consumer does not pay a trade invoice when due
A business does not pay an employee's earned wages when due
A business or government bond issuer does not make a payment on a coupon or principal payment when due
An insolvent insurance company does not pay a policy obligation
An insolvent bank won't return funds to a depositor
A government grants bankruptcy protection to an insolvent consumer or business.
Assessing credit risk
Significant resources and sophisticated programs are used to analyze and manage risk. Some companies run a credit risk department whose job is to assess the financial health of their customers, and extend credit (or not) accordingly. They may use in house programs to advise on avoiding, reducing and transferring risk. They also use third party provided intelligence. Companies like Standard & Poor's, Moody's, Fitch Ratings, and Dun and Bradstreet provide such information for a fee.
Most lenders employ their own models (credit scorecards) to rank potential and existing customers according to risk, and then apply appropriate strategies. With products such as unsecured personal loans or mortgages, lenders charge a higher price for higher risk customers and vice versa. With revolving products such as credit cards and overdrafts, risk is controlled through the setting of credit limits. Some products also require security, most commonly in the form of property.
Credit scoring models also form part of the framework used by banks or lending institutions grant credit to clients. For corporate and commercial borrowers, these models generally have qualitative and quantitative sections outlining various aspects of the risk including, but not limited to, operating experience, management expertise, asset quality, and leverage and liquidity ratios, respectively. Once this information has been fully reviewed by credit officers and credit committees, the lender provides the funds subject to the terms and conditions presented within the contract (as outlined above).
Sovereign risk
Sovereign risk is the risk of a government becoming unwilling or unable to meet its loan obligations, or reneging on loans it guarantees.[1] The existence of sovereign risk means that creditors should take a two-stage decision process when deciding to lend to a firm based in a foreign country. Firstly one should consider the sovereign risk quality of the country and then consider the firm's credit quality.
Five macroeconomic variables that affect the probability of sovereign debt rescheduling are:
Debt service ratio
Import ratio
Investment ratio
Variance of export revenue
Domestic money supply growth
The probability of rescheduling is an increasing function of debt service ratio, import ratio, variance of export revenue and domestic money supply growth. Frenkel, Karmann and Scholtens also argue that the likelihood of rescheduling is a decreasing function of investment ratio due to future economic productivity gains. Saunders argues that rescheduling can become more likely if the investment ratio rises as the foreign country could become less dependent on its external creditors and so be less concerned about receiving credit from these countries/investors.
Counterparty risk
Counterparty risk, otherwise known as default risk, is the risk that an organization does not pay out on a bond, credit derivative, credit insurance contract, or other trade or transaction when it is supposed to.Even organizations who think that they have hedged their bets by buying credit insurance of some sort still face the risk that the insurer will be unable to pay, either due to temporary liquidity issues or longer term systemic issues.
Large insurers are counterparties to many transactions, and thus this is the kind of risk that prompts financial regulators to act, e.g., the bailout of insurer AIG.
On the methodological side, counterparty risk can be affected by wrong way risk, namely the risk that different risk factors be correlated in the most harmful direction. Including correlation between the portfolio risk factors and the counterparty default into the methodology is not trivial.
Mitigating credit risk
Lenders mitigate credit risk using several methods:
Risk-based pricing: Lenders generally charge a higher interest rate to borrowers who are more likely to default, a practice called risk-based pricing. Lenders consider factors relating to the loan such as loan purpose, credit rating, and loan-to-value ratio and estimates the effect on yield (credit spread).
Covenants: Lenders may write stipulations on the borrower, called covenants, into loan agreements:
Periodically report its financial condition.
Refrain from paying dividends, repurchasing shares, borrowing further, or other specific, voluntary actions that negatively affect the company's financial position.
Repay the loan in full, at the lender's request, in certain events such as changes in the borrower's debt-to-equity ratio or interest coverage ratio.
Credit insurance and credit derivatives: Lenders and bond holders may hedge their credit risk by purchasing credit insurance or credit derivatives. These contracts the transfer risk from the lender to the seller (insurer) in exchange for payment. The most common credit derivative is the credit default swap.

These contracts the transfer risk from the lender to the seller (insurer) in exchange for payment. The most common credit derivative is the credit default swap.
Tightening: Lenders can reduce credit risk by reducing the amount of credit extended, either in total or to certain borrowers. For example, a distributor selling its products to a troubled retailer may attempt to lessen credit risk by reducing payment terms from net 30 to net 15.
Diversification: Lenders to a small number of borrowers (or kinds of borrower) face a high degree of unsystematic credit risk, called concentration risk. Lenders reduce this risk by diversifying the borrower pool.
Deposit insurance: Many governments establish deposit insurance to guarantee bank deposits of insolvent banks. Such protection discourages consumers from withdrawing money when a bank is becoming insolvent, to avoid a bank run), and encourages consumers to holding their savings in the banking system instead of in cash.
