One objective of credit analysis is to look at both the borrower and the lending facility being proposed and to assign a
risk rating. The risk rating is derived by estimating the
probability of default by the borrower at a given
confidence level over the life of the facility, and by estimating the
amount of loss that the lender would suffer in the event of default. Credit analysis involves a wide variety of
financial analysis techniques, including
ratio and trend analysis as well as the creation of projections and a detailed analysis of cash flows. Credit analysis also includes an examination of
collateral and other sources of repayment as well as credit history and management ability. As mentioned, analysts attempt to predict the probability that a borrower will default on its debts, and also the severity of losses in the event of default. The
credit spread is the difference in
interest rates between theoretically "risk-free" investments such as U.S. treasuries or LIBOR and investments that carry some risk of default—reflect credit analysis by financial market participants. Before approving a
commercial loan, a bank will look at all of these factors with the primary emphasis being the cash flow of the borrower. A typical measurement of repayment ability is the
debt service coverage ratio or DSCR. A
credit analyst at a bank will measure the cash generated by a business (before interest expense and excluding
depreciation and any other non-cash or extraordinary expenses). The DSCR divides this cash flow amount by the debt service (both principal and
interest payments on all loans) that will be required to be met. Commercial bankers prefer a DSCR of at least 120 percent. In other words, the debt service coverage ratio should be 1.2 or higher to show that an extra cushion exists and that the business can afford its debt requirements. == Classic credit analysis ==
