Adequate loan classification practices are an essential part of a sound and effective credit risk-management process in a bank. Failure to identify deterioration in credit quality in a timely manner can aggravate and prolong the problem. Two key issues arise with regard to the use of collateral in the context of loan classification and provisioning. In particular, the questions arise whether collateral should be taken into account in classifying a collateralized loan, and whether it should be considered in calculating provisions. This paper surveys country practices in the role of collateral in loan classification and provisioning, and suggests good practices on these issues.

This research report looks at the loan classification and provisioning practices used in a broad variety of countries in terms of size, location and level of financial development. Aspects covered include: classifications of individual and multiple loans, treatment of guarantees and collateral, bank loan review processes, loan loss provisioning, tax treatment of loan loss provisions, disclosure standards, and the role of external auditors.

Recent debate about the pro-cyclical effects of bank capital requirements, has ignored the important role that bank loan loss provisions play in the overall framework of minimum capital regulation. It is frequently observed that under-provisioning, due to inadequate assessment of expected credit losses, aggravates the negative effect of minimum capital requirements during recessions, because capital must absorb both expected, and unexpected losses. Moreover, when expected losses are properly reflected in lending rates, but not in provisioning practices, fluctuations in bank earnings magnify true oscillations in bank profitability. The relative agency problems faced by different stakeholders, may help explain the prevailing, and often unsatisfactory institutional arrangements. The authors test their hypotheses with a sample of 1,176 large commercial banks - 372 of them in non-G10 countries - for the period 1988-99. After controlling for different country-specific macroeconomic, and institutional features, they find robust evidence among G10 banks, of a positive association between loan loss provisions, and banks' pre-provision income. Such evidence is not confirmed for non-G10 banks, which on average, provision too little in good times, and are forced to increase provisions in bad times. The econometric evidence shows that the protection of outsiders' claims - the claims of minority shareholders in common law countries, and of fiscal authorities in countries with high public debt - on bank income, has negative effects on the level of bank provisions.

The NBRB revised in 2018 its regulation on asset classification and provisioning (the Regulation). One of the main changes was the introduction of a new definition for NPLs based on the current framework of risk groups (RGs). This definition substitutes the previous term “problem assets.” One of the intentions of the replacement is to promote international comparability by using it as a financial soundness indicator (FSI). The reported levels of this new NPLs indicator are, however, relatively low and, more important, much lower than the previous indicator, based on problem assets. The new NPL indicator levels are relatively stable, around 4 percent. The previous indicator was also stable, but the levels were more than three times higher, about 13 percent.

High and persistent levels of nonperforming loans (NPLs) have featured prominently in recent financial crises. This book traces NPL trends during and after crises, examines the economic impact of high NPLs, and compares the effectiveness of NPL resolution strategies across economies in Asia and Europe. The book distills important lessons from the experiences of economies using case studies and empirical investigation of ways to resolve NPLs. These findings can be invaluable in charting a course through the financial and economic fallout of the coronavirus disease (COVID-19) pandemic to recovery and sustained financial stability in Asia, Europe, and beyond.
