This work intends to study some problems in relation to the issuance of letters of credit. Those problems are the delay of issuing letters of credit, the reissuing letters of credit, and the issuing letters of credit in the third party's name. Sellers and buyers must keep in mind that the supply of letter of credit by buyer is the condition precedent for a seller's shipment obligation. A seller has no obligation to ship the goods until he receives the letter of credit by buyer's bank, issuing bank. An issuing bank can have the risk that an original letter of credit and a reissued letter of credit can be used double in the exporting country. The most safe method for issuing bank is to cancel the original letter of credit and to reissue a new letter of credit. When an issuing bank issues a letter of credit in the third party's name, the bank should investigate the background of the transaction and give the buyer a proper line of credit.

Most researches on the corporate credit rating are generally classified into the area of bankruptcy prediction and bond rating. The studies on bankruptcy prediction have focused on improving the performance in binary classification problem, since the criterion variable is categorical, bankrupt or non-bankrupt. The other studies on bond rating have predicted the credit ratings, which was already evaluated by bond rating experts. The financial institute, however, should perform effective loan evaluation and risk management by employing the corporate credit rating model, which is able to determine the credit of corporations. Therefore, this study presents a corporate credit rating method using business failure probability map(BFPM) and AHP(Analytic Hierarchy Process). The BFPM enables us to rate the credit of corporations according to business failure probability and data distribution or frequency on each credit rating level. Also, we developed AHP model for credit rating using non-financial information. For the purpose of completed credit rating model, we integrated the BFPM and the AHP model using both financial and non-financial information. Finally, the credit ratings of each firm are assigned by our proposed method. This method will be helpful for the loan evaluators of financial institutes to decide more objective and effective credit ratings.

This paper proposes an integrated risk-management framework that includes 1) measuring the risk of credit portfolios, 2) implementing a (macro) stress test, and 3) setting risk limits using the estimated systematic latent factor specific to capture the housing market cycle. To this end, we extract information from a set of real-estate market variables based on the FAVAR methodology proposed by Bernanke, Boivin and Eliasz (2005). Then, we show the method by which the estimated systematic factor is applied to risk management in the housing market in an integrated manner within the Vasicek one-factor credit model. The proposed methodology is well fitted to analyze the risk of slow-moving and low-defaultable forms of capital, such as alternative investments.

수출신용보증은 수출계약과 관련하여 외국환은행이 중소기업자인 수출업자에게 수출신용보증서를 담보로 대출함에 따라 발생하는 수출자의 상환채무에 대하여 한국무역보험공사가 그 지급을 연대보증하는 것으로 외국환은행은 안심하고 수출금융을 취급할 수 있다. 또한 중소기업 수출자도 별도의 담보를 제공하지 않아 현재 중소기업은 전용보증제도인 수출보험제도를 가장 선호하고 있다. 하지만 한국무역보험공사가 지원하는 수출신용보증의 경우 최근 5년간 인수실적이 공사 전체 인수실적(보험 및 보증인수 총액, 총 604조여 원)의 2.64%(16조여 원)에 불과한데도 5,262억 원의 보험수지 적자가 발생하는 등 무역기금손실의 주요 요인으로 작용하고 있다. 따라서 본고에서는 중소기업의 건전한 수출지원 정책으로서 안정적인 무역금융지원기반을 마련하고 기금운용의 건전성 확보와 절감 방안을 검토하기 위해 2011년 11월 감사원의 무역보험실태 보고서를 토대로 수출신용보증제도의 사례분석을 통해 문제점을 고찰하고 무역보험운용상의 개선방안을 도출하고자 한다.

정부는 신용평가시스템을 객관화하여 회생가능성이 있는 기업은 자금을 지원하고, 회생가능성이 없는 기업은 조기에 구조조정을 추진하는 방안을 발표하였다. 이러한 정부발표는 자본시장을 통한 구조조정의 기반을 강화하여 신속한 구조조정이 이루어질 수 있는 기틀을 마련함으로써 재무건전성이 낮은 중견건설사는 구조조정 위험에 확대될 수 있다. 본 연구는 2019년 기준으로 주택사업에 집중된 10개 중견건설사를 선정하여 은행의 재무심사기법을 통해 재무건전성을 분석하였고, 이러한 분석결과를 통해 구조조정 위험에 노출될 가능성이 높음을 확인할 수 있었다. 2020년에는 경제성장률 하락과 부동산규제 강화로 건설업 성장률이 전반적으로 하락될 것으로 판단되어 자본금 납입비율이 낮은 중견건설사는 안정적인 신용등급을 유지할 가능성이 낮아 구조조정에 포함될 가능성이 높다. 본 연구는 중견건설사가 구조조정 위험에서 벗어날 수 있도록 공신력 있는 연구기관의 자료를 활용하여 KCSI 평가모델을 설정하였고, 실무전문가 설문조사를 통해 각 항목마다 차별화된 위험비율을 나타냈다. 이러한 연구결과는 중견건설사 경영진에게 신용리스크 저감방안을 실천하도록 제언할 수 있었고, 구조조정 위험에 벗어날 수 있는 기틀을 마련하였다.

The credit rating represents an assessment of the relative level of risk associated with the timely payments required by the debt obligation. In this paper, we present a new approach to credit rating of customers based on the rough set theory. The concept of a rough set appeared to be an effective tool for the analysis of customer information systems representing knowledge gained by experience. The customer information system describes a set of customers by a set of multi-valued attributes, called condition attributes. The customers are classified into groups of risk subject to an expert's opinion, called decision attribute. A natural problem of knowledge analysis consists then in discovering relationships, in terms of decision rules, between description of customers by condition attributes and particular decisions. The rough set approach enables one to discover minimal subsets of condition attributes ensuring an acceptable quality of classification of the customers analyzed and to derive decision rules from the customer information system which can be used to support decisions about rating new customers. Using the rough set approach one analyses only facts hidden in data, it does not need any additional information about data and does not correct inconsistencies manifested in data; instead, rules produced are categorized into certain and possible. A real problem of the evaluation of the evaluation of credit rating by a department store is studied using the rough set approach.

국내 외에서 지급보증과 관련 모회사의 지원 중단으로 신용평가사로부터 높은 등급을 받았던 자회사가 법정관리에 갔던 사태로 투자자의 피해가 발생한 사례가 존재하여 이에 모기업 계열사의 지원 가능성을 배제한 기업의 자체신용도 또는 독자신용등급에 대한 관심이 높아지고 있다. 본 연구에서는 해외자회사를 둔 국내 기업을 대상으로 판별력 분석, 등급화 분석 그리고 안정성 분석을 통해 기업 신용평가모형의 적합성검증을 실시하였으며 주요 실증분석결과 해외자회사의 부도 현황을 볼 때 부도율측면에 있어서 국내모회사보다 상대적으로 낮은 부도율을 나타내고 있는 것을 확인할 수 있었고, 한국모회사가 지급보증을 하는데 있어 해외자회사보다 신용등급이 일반적으로 높은 것으로 나타났다.

Currently, Korean firms are making a lot of effort to invest in research and development (R&D) by spending a lot of development costs in order to cope with the 4th industrial revolution. On the other hand, the capital market of Korea, which is the main source of funding, has caused a lot of cost of capital for firms by its reorganization mainly with safe assets in the experience of foreign exchange crisis at the end of 1997, the sub-prime mortgage crisis in 2007 and the bankruptcy of Lehman Brothers in September 2008. Thus, this study empirically analyzed the effect of development expenses on credit rating and firm value. The credit rating was measured by commercial paper(CP) credit rating which is sensitive for investors in terms of risk because it is issued only by the credit of the firms. Firm value was defined as Tobin's Q, which has been widely used in prior studies. The results of the analysis are summarized as follows; Firstly, development expenses did not affect credit rating. Development expenses are recognized as intangible assets for uncertainty of economic benefits and long-term investment. Thus, it seems that there is no effect of development expenses on CP credit rating as CP credit rating is evaluated by short-term credit rating.

In this paper, we deal with the pricing of vulnerable power exchange option. We consider the hybrid model as the credit risk model. The hybrid model consists of a combination of the reduced-form model and the structural model. We derive the closed-form pricing formula of vulnerable power exchange option based on the change of measure technique.

The study uses the audited financial statements of 26 Vietnamese commercial banks listed on the Ho Chi Minh City Stock Exchange (HOSE) and Hanoi Stock Exchange (HOSE) during the 2008-2018 period to estimate the system GMM model, which provides empirical evidence on the effect of the variables of customer deposit to total assets (DEPO) ratio, loan to assets (LTA) ratio, liquidity of commercial banks (LIQ), credit development (CRD) ratio, external funding (EFD) ratio, and credit loss provision (LLP) ratio on liquidity risk. The study confirms that commercial banks' internal factors play the most important role, and there is no empirical evidence on macro variables that affect liquidity risk. Finally, in accordance with the theoretical framework, the study uses an estimation method with the R language and the bootstrap methodology to give empirical proof of the nonlinear correlation and U-shaped graph between commercial bank size and liquidity risk. The importance of commercial bank size in absorbing and moderating the effects of liquidity shocks is demonstrated, however, excessive growth in commercial bank size would increase liquidity risk in commercial bank operations.
