A line of credit is one of the most flexible financing tools for companies. Banks give companies lines of credit to strengthen their profitability and competitive ability. On the other hand, companies draw the lines of credit that will increase banks' credit risk. It is very difficult for banks to determine the lines of credit for an enterprise group. Based on principle of credit risk evaluation and structural model, this paper first defines bank's tolerable default risk and lines of credit, and then analyzes integrated lines of credit of parent and subsidiary companies. The results of this research indicate that the lines of credit of single company is related to its asset value growth, and integrated lines of credit of an enterprise group is also related to member's asset value growth and the associated relationships. Furthermore, this study shows that the integrated lines of credit of an enterprise group can be determined by the weighted sum of member's lines of credit and the computational formula of weight. This study provides a quantitative analysis tool to ascertain the enterprise group's integrated lines of credit and analyze how the associated relationships affect the integrated lines of credit.

AbstractThis article proposes a structural model for sovereign credit risk with endogenous sovereign debt and default policies. A maximum-likelihood estimation of the model with local stock market prices generates daily model-implied sovereign spreads. This approach explains two-thirds of the daily variation in observed sovereign spreads for emerging and European economies over the 2000–2011 period. Global factors help to further explain the time variation in sovereign credit risk. In particular, sovereign spreads in emerging markets vary with U.S. market uncertainty, whereas European spreads depend on Euro-zone bond factors.

Limiting Case

In this paper, we develop a new structural model that allows for a distinction between default and liquidation to be made. Default occurs when firm’s asset value process crosses a bankruptcy barrier. Here, we do not assume that default immediately triggers liquidation. Instead, the firm is allowed to continue operating even if it is in default. Liquidation is triggered as soon as the firm’s asset value has cumulatively spent a prespecified amount of time below the default barrier or has dropped below the liquidation barrier. The proposed model includes the Black–Cox model as a limiting case. A semi-analytical formula of the liquidation probability is derived for the case where firm’s asset value follows a geometric Brownian motion. Nonlinear volatility diffusion models are discussed as well.

Payoff Condition

This paper develops a simple model to study the credit risk premiums of credit-linked notes using the structural model. Closed-form solutions of credit risk premiums of the credit-linked notes derived from the model as functions of firm values and the short-term interest rate, with time-dependent model parameters governing the dynamics of the firm values and interest rate. The numerical results show that the credit spreads of a credit-linked note increase non-linearly with the decrease in the correlation between the asset values of the note issuer and the reference obligor when the final payoff condition depends on the asset values of the note issuer and the reference obligor. When the final payoff condition depends on the recovery rate of the note issuer upon default, the credit spreads could increase with the correlation. In addition, the term structures of model parameters and the correlations involving interest rate are clearly the important factors in determining the credit spreads of the notes.

Model Approach

Liability drives insurers' businesses. This paper examines the structural model approach of credit risk for the valuation of insurance liabilities and insurers' equity, and considers a stochastic process for liability. Grosen and Jørgensen's (2002) study presents the current approach taken by insurers; however, the model's structure is very simple, and its liability structure in particular has a deterministic time function. In contrast, we analyze a model that analytically evaluates an insurer's liability with the stochastic process. Furthermore, we analyze the model's default option originally presented by Myers and Read (2001).

At the core of the recent global financial and economic crisis marked by its magnitude, credit risk turned out to be a powerful catalyst. The objective of this paper is mainly to follow up on the evolution of credit risk on the Jordanian market during the recent economic and financial international crisis. Based on the linear discriminant Z-Score model and KMV structural model, we recognize the increase in credit risk during the crisis period. On the whole, the confrontation between models highlights the robust correlation between the accounting results of a company and its market value and therefore indicates the need to consider the macroeconomic context in an open economy for the evaluation of the risk of credit.   JEL codes: E551, G3, C1
