Risk arising from single issuer credit events
So far we have described a rather intuitive way of combining individual views in a portfolio. Top-down and bottom-up analyses have determined the overall strategy for the portfolio, spread class and sector selection and finally issuer weightings. This qualitative methodology does not require estimates of returns, risks and correlations between the investments, and therefore is easy to implement. Yet, it is not able to capture the full benefits of diversification and to tailor the expected risk/return profile of the portfolio to the preferences of the investor. Since the seminal work of Markowitz (1952), diversification is a central tenet of modern investment theory. In the context of credit portfolios it plays a crucial role, because it helps to control downside risk arising from single issuer credit events. Since the mid-1990s debt-financed M&A activities, share buybacks, and the introduction of new technologies have fueled the new issue pipeline and broadened the corporate bond universe. Meanwhile, the European corporate bond market offers sufficient market breadth and depth for institutional investors to construct thoroughly diversified portfolios. If the portfolio manager is capable of quantifying the risk and return characteristics of his investment alternatives, portfolio optimization approaches present a formalized and thus objective way of deriving investment recommendations. This applies irrespective of the performance target of the investor. Portfolio optimization can be used with respect to portfolios that are managed in absolute risk/ return terms as well as portfolios that are managed relative to a benchmark index.. Various constraints can be included, for example a short sales restriction for real money investors, maximum concentration limits or desired duration ranges.
Assessments of an issuer’s credit quality
The rating agencies have been criticized for being too slow to react to changes in the credit quality of an issuer, leading to serially correlated rating patterns and limiting the value of ratings as a risk management tool. As a reaction, Moody’s decided to put its rating process under review, and acquired KMV to be able to provide investors with additional, marketbased assessments of an issuer’s credit quality. The feedback from market participants was surprising. Since investors themselves tend to use spreads and spread volatility as indicators for credit risk, the vast majority does not want Moody’s or the other rating agencies to switch to a more marketbased approach when assessing the credit quality of an issuer. There is really a need for, according to the feedback, more transparency with regard to the rating process. This would allow investors to use rating agency information in their risk management most efficiently.
Perceived credit quality and risk exposure
For purposes of risk management bonds are often grouped according to agency ratings based on the assumption that bonds with similar ratings tend to show a high degree of comovement. Breger et al. (2003) examine whether the correlation between individual bonds increases if they are grouped by implied ratings, that is by spread classes rather than by agency ratings. The rationale for this would be that market valuations are a better indicator for the drivers of credit spread changes, namely perceived credit quality and risk exposure, than are agency ratings. In their empirical study they find that bonds of the same spread class are more similar than bonds with the same rating from a risk/return perspective. Breger et al. (2003) conclude that the classification of bonds based on market data provides a more reliable basis for modeling return relationships than does a classification by agency ratings. However, one has to note that the motivation behind this study differs significantly from the rating agencies’ approach. The objective is not to predict default risk, but rather to improve the classification of corporate borrowers and provide a basis for reliable spread risk forecasts.
Downgrading your loan is a good solution
The addition of the individual contributions to expected excess return in Experience yields an expected 1-year excess return of 88.2 bp for A-rated corporate bonds with a maturity of 5-years. This is significantly below the initial spread of 100 bps. The difference reflects the fact that a downgrade is more probable for A-rated corporate bonds than an upgrade, and that the associated spread changes are not symmetric. The magnitude of spread widenings due to downgrades is usually much higher than the spread tightening after rating upgrades. It is interesting to note that among investment grade bonds the ratio of upgrades to downgrades is most favorable for Baa-rated bonds. However, in the case of a downgrade these bonds often suffer massive price declines, because they fall below investment
grade levels.
Credit exposure to foreign currencies
European telecom companies have their operations primarily in Europe. Therefore, exposure to foreign currencies is very limited with the exception of Telefonica’s exposure to Latin America and Deutsche Telekom’s US subsidiaries. While in other industries an appreciating Euro increases competition, it appears that this effect should be negligible for the established European telecom services companies. The barriers of entry seem to be high enough to guarantee broadly stable market shares in the coming years. Since many of the telecom companies have a material fraction of their debt in US dollars, they would benefit from a strengthening Euro.
It is in the nature of financial institutions to have exposure to a variety of currencies. Exchange rate risk is therefore translational rather than transactional. By and large, long-term currency risk is primarily taken in the form of subsidiaries. Currency fluctuations change the value of the equity invested, hence are reflected in the balance sheet rather than in the P&L. Of the larger European banking groups, ABN Amro, BNP Paribas and Royal Bank of Scotland have substantial retail banking operations in the United States. In the insurance sector, Aegon, AXA, ING Verzekeringen and Prudential stand out in terms of US exposure.
The impact of credit on operating income
The paper sector is only mildly exposed, since in general companies generate no more than 20 percent of their revenues in the United States. The more internationally oriented technology and chemical companies like Siemens, Philips and Akzo generate about 30 percent of sales in the United States, and have substantial further sales outside the Euro area. Yet, the impact on operating income is reduced by the fact that a significant part of costs accrues in US operations. Additionally, most industrial companies engage in hedging activities. Among the companies with a high exposure to currency risk are UK companies FKI and Pearson that both generate more than 60 percent of sales in the United States. When the US dollar depreciates significantly, these companies are hit hardest.
With respect to their vulnerability against currency movements, companies from the consumer sector benefit from their broad geographic diversification.
It appears to be common policy to match assets and liabilities in the various regions to minimize overall currency risk. However, while transaction risk is accounted for, companies tend to leave translation risk unhedged. But many of the well-known European consumer companies like Nestle and Unilever have been able to raise funds in US dollars. Thus US dollar denominated debt exceeds assets and earnings. During the US dollar weakness those companies have seen their debt and interest burden diminish faster than their earnings. UK tobacco companies tend to finance a significant part of their business with Euro denominated debt, leaving them exposed to a strengthening of the Euro versus Sterling.
Loans are particularly exposed to currency movements
Being one of the most global sectors, the automotive sector is particularly exposed to currency movements. Significant changes of major exchange rates therefore may have a material impact on earnings. Yet, some manufacturers are better positioned than others due to a number of factors that do not only relate to natural or derivatives hedging. Awell-filled model pipeline, restructuring plans, cost reduction issues and a high degree of flexibility in the use and sourcing of raw materials and intermediate goods may outweigh negative effects due to currency fluctuations. With regard to transaction risk, those companies that have no foreign exchange exposure or are hedged, either naturally or through derivatives, clearly have the lowest risk. In terms of translation risk, companies whose assets and liabilities are well matched have the lowest risk and will have the lowest volatility of operating profits.
During the 2002/03 US dollar weakness, revenues and to a lesser extent operating profits of most European industrial issuers suffered significantly due to substantial US operations. However, exposure to US markets varies across industries.
Credit and the appreciation of the local currency
The third effect of currency fluctuations refers to the fact that the appreciation of the local currency attracts imports from abroad. Usually, the import competition effect only becomes apparent, when the currency appreciation has been sustained for some time. While companies are quick to cite the impact of exchange rate movements on revenues, profits and liabilities, the longer term effects with regard to market share and prices are hard to quantify.
Ultimately increased competition through cheaper imports can cause earnings erosion in the domestic markets. On the other hand, European car makers benefited from the weak Euro in 2000 and 2001 through increased exports to the United States.
Although in the age of globalization, currency fluctuations may have an impact on most companies earnings, some sectors are more vulnerable to the currency issue than others. In general, the industrial, and here most notably the capital goods sector, and the automotive sector are particularly exposed. Especially from a longer perspective, the impact varies on the company level, when (natural) hedges are taken into account. While the European utilities and telecom sector have a relatively low exposure to the US dollar, they are more impacted by fluctuations of emerging market currencies.
When payday translation risk arises
When financial accounts are converted from one currency to another, translation risk arises. Typically, the financial accounts of foreign subsidiaries have to be translated back in the reporting currency to be included in the consolidated financial accounts. Since most companies do not hedge translation risk, significant changes in exchange rates during the reporting period can cause volatility in revenues and operating income. Usually companies present constant exchange rate revenues as an addition to reported revenues, to allow investors and creditors to analyze the effect of currency fluctuations.
However, a secular depreciation of the US dollar positively affects those European companies with part of their liabilities denominated in US dollars. Not only the amount of debt shown on the balance sheet is reduced, but also the associated interest burden is lessened. In terms of credit ratios, the issuance of debt in a currency, in which part of the revenues are generated, can provide an effective natural hedge against exchange rate volatility. For example, if profits of a European company operating in the United States were reduced by a weakening US dollar, it may be offset by a contemporaneous reduction of the level of US dollar denominated debt. In this case, credit ratios as well as interest coverage ratios could remain constant or even improve. It should be noted that revenues and earnings typically accrue gradually, hence they are translated at average exchange rates, while balance sheet figures are usually determined at the end of reporting period spot rates.
A currency mismatch between credit and revenues
Transaction risk arises when a company has a currency mismatch between its costs and revenues, that is, revenues are generated in one currency while costs are denominated in another, the reporting currency. The sustained depreciation of the US dollar since February 2002, for example, has negatively affected the P&L and cash flow statements of European exporters.
Although it proves difficult to obtain a breakdown of the cost structure of a company by currency, the automotive sector and the aerospace sector seem to be hit most by transaction risk.
Therefore, many companies try to offset at least a part of their currency exposure via natural hedging. That is, they try to match currency flows that result from exports and imports of goods and services. A high degree of flexibility with respect to input factors and capacity utilization of plants in different regions also provides an effective hedge against adverse currency movements. Another possibility of reducing currency risk is through derivatives, primarily forward exchange contracts and currency options. In our experience most companies that are significantly exposed to currency risk use some form of derivatives hedging. Yet, most contracts are set up for a period of 1–2 years at most. In the long term, it is difficult for companies to assess their demand for hedging because they have no reliable information
about the future demand for their products and services so that the future cost and earnings situation is unknown. For longer term trends in exchange rates, natural hedging usually is more effective. Credit analysts often lack a thorough insight in currency hedging strategies, especially with regard to derivatives hedging. Since they are hardly able to assess the true currency exposure in the short term, they tend to prefer the longer term and more transparent natural hedging strategies.
