Der Umgang mit Risiken im Unternehmen der Realwirtschaft und die nachhaltige Steuerung dieser Risiken haben aufgrund der wirtschaftlichen Entwicklungen seit 2008 stark an Bedeutung gewonnen, so die Experten des Wirtschaftsprüfers PricewaterhouseCoopers (PWC) in der Studie "Risk-Management-Benchmarking 2010". Unternehmen müssen auch in wirtschaftlich volatilen Situationen in der Lage sein, Risiken frühzeitig zu erkennen, die Gesamtrisikosituation zu bewerten und durch Einleiten adäquater Gegenmaßnahmen auf sie zu reagieren. Die Benchmark-Studie zeigt auf, wie sich deutsche Großunternehmen der Realwirtschaft aktuell dieser Herausforderung stellen und wie ihr Risikomanagementsystem (RMS) ausgestaltet ist.

Um im zunehmend dynamischeren Umfeld flexibler auf Chancen und Risiken reagieren zu können, sind Delegation und Dezentralisierung wichtige Maßnahmen. Es ist jedoch nur ein Teil des Weges: Nur wer dieses kombiniert mit der gedanklichen Auseinandersetzung und Integration von Chancen und Risiken über Organisationseinheiten hinweg, wird auch langfristig erfolgreich sein. Szenarien und betriebswirtschaftliche Simulationen sind geeignete Methoden mit unbestrittenem Nutzen für das Management von Chancen und Risiken, aber bisher eher sporadischer Anwendung. Dabei ist ihre Nutzung bei Berücksichtigung einiger Kriterien zur Auswahl des passenden Ansatzes überraschend unkompliziert.

"Arbitrage CDOs" have recorded an explosive growth during the years before the outbreak of the financial crisis. In the present paper we discuss potential sources of such arbitrage opportunities, in particular arbitrage gains due to mispricing. For this purpose we examine the risk profiles of Collateralized Debt Obligations (CDOs) in some detail. The analyses reveal significant differences in the risk profile between CDO tranches and corporate bonds, in particular concerning the considerably increased sensitivity to systematic risks. This has farreaching consequences for risk management, pricing and regulatory capital requirements. A simple analytical valuation model based on the CAPM and the single-factor Merton model is used in order to keep the model framework simple. Then, the conditional expected loss curve (EL profile) is studied in some detail. In the next step, the asset correlation associated with a CDO tranche is estimated treating the structured instrument as a single-name credit instrument (i.e., a loan equivalent). While tractable, the loan-equivalent approach requires appropriate parameterization to achieve a reasonable approximation of the tranche´s risk profile. We consider the tranche as a "virtual" borrower or bond for which a single-factor model holds. Then, the correlation parameter is calculated via a non-linear optimization. This "bond representation" allows to approximate the risk profile (expressed by the EL profile) using a single-factor model and to express the dependence on the systematic risk factor via the corresponding asset correlation. It turns out that the resulting asset correlation is many times higher than that of straight bonds. Then, the Merton type valuation model for the corresponding bond representations is applied for valuation of the CDO tranches. Using a sample CDO portfolio, some opportunities for "CDO arbitrage" are described where it is assumed that investors are guided solely by the tranches’ rating and ignore the increased systematic risk for pricing. In the next section we discuss how tranches with high systematic risk can be generated and how CDO arrangers can exploit this to their advantage. It comes as no surprise that precisely these types of structures featured in many of the CDOs issued prior to the outbreak of the financial crisis.

Spätestens 2007/2008 ist offensichtlich geworden, dass Risikokonzentrationen in den Finanzinstituten noch nicht ausreichend berücksichtigt werden. Expliziten Handlungsbedarf signalisiert auch die Bankenaufsicht, zuletzt durch den MaRisk-Entwurf vom 9. Juli 2010. Die Integration von Risikokonzentrationen in die Prozesse des Risikomanagements- und -controllings ist wohl ein wesentlicher Meilenstein für den Ausbruch aus dem Denken in einzelnen Risikoarten-Silos. Auf diesem Weg sind jedoch noch einige Hürden zu überwinden. Dies wird nachfolgend am Beispiel der Bewertung von Risikokonzentrationen gezeigt.

A major source of risk in project management is inaccurate forecasts of project costs, demand, and other impacts. The paper presents a promising new approach to mitigating such risk based on theories of decision-making under uncertainty, which won the 2002 Nobel Prize in economics. First, the paper documents inaccuracy and risk in projectmanagement.
Second, it explains inaccuracy in terms of optimism bias and strategic misrepresentation. Third, the theoretical basis is presented for a promising new method called "reference class forecasting", which achieves accuracy by basing forecasts on actual performance in a reference class of comparable projects and thereby bypassing both optimism bias and strategic misrepresentation. Fourth, the paper presents the first instance of practical reference class forecasting, which concerns cost forecasts for large transportation infrastructure projects. Finally, potentials for and barriers to reference class forecasting are assessed.

The liberalization of electricity markets has forced the energy producing companies to react to the new situation. The abolishment of monopolies and the launch of open markets have increased the need of calculating costs closer to the profit frontier to be still competitive, not only against the other German but also against foreign suppliers. Thus, an efficient risk management and risk controlling are needed to ensure the financial survival of the company even during bad times. In this work we use the RAROC methodology to develop a Monte Carlo Simulation based model to quantify risks related to wholesale electricity contracts, also called full load contracts. We do not only consider risk due to market price fluctuations but also due to correlation effects between the spot market price and the load curve of a single customer.

Risk management is an increasingly important business driver and stakeholders have become much more concerned about risk. Risk may be a driver of strategic decisions, it may be a cause of uncertainty in the organisation or it may simply be embedded in the activities of the organisation. An enterprise-wide approach to risk management enables an organisation to consider the potential impact of all types of risks on all processes, activities, stakeholders, products and services. Implementing a comprehensive approach will result in an organisation benefiting from what is often referred to as the ‘upside of risk’. The global financial crisis in 2008 demonstrated the importance of adequate risk management. Since that time, new risk management standards have been published, including the international standard, ISO 31000 ‘Risk management – Principles and guidelines’. This guide draws together these developments to provide a structured approach to implementing enterprise risk management (ERM).

SEI Mission-Oriented Success Analysis and Improvement Criteria (MOSAIC) is a management approach for establishing and maintaining confidence that objectives will be achieved successfully. It comprises a suite of risk-based methods for assessing and managing complex projects and processes. The Mission Diagnostic Protocol (MDP) is one of the assessments included in MOSAIC. MDP provides a time-efficient means of analyzing the potential for success in complex and uncertain environments and can be applied across the life cycle and throughout the supply chain. It produces a broad overview of the current state of risk and opportunity for a project or process. With MDP, a set of key drivers is evaluated to establish current conditions and circumstances that can affect performance. Then, a simple algorithm is used to estimate the likelihood of achieving the objectives being pursued. An MDP assessment is straightforward to conduct, and it can be self-applied by people who are responsible for overseeing projects and processes. The purpose of this document is to describe the core set of activities and outputs that defines MDP.

Um nachhaltig eine risikoadjustierte Outperformance im Private Wealth Management zu erzielen, ist die kontinuierliche Weiterentwicklung des Portfoliomanagements erforderlich. Notwendig sind spezielle Instrumente, die moderne Bewertungsmethoden und Ergebnisse der empirischen Kapitalmarktforschung nutzen und insbesondere nicht auf den Standardannahmen der Theorie vollkommener Kapitalmärkte basieren.

Der Deutsche Bundestag und der Bundesrat haben 2009 das "Gesetz zur Änderung des Bundesdatenschutzgesetzes" (BDSG-Novelle I) betreffend Scoring und Auskunfteien beschlossen, das zum 1. April 2010 in Kraft getreten ist. Ziel der neuen Regelungen ist es unter anderem die Transparenz beim Einsatz von Scoring-Verfahren zu erhöhen. Unternehmen und Auskunfteien sind somit seit Anfang April 2010 dazu verpflichtet, ihren Kunden auf Anfrage deren Scoring schriftlich und verständlich offen zu legen. Wir stellen in diesem Beitrag den rechtlichen Rahmen dieser Gesetzesnovelle vor und entwickeln daraufhin ein Modell, welches eine Offenlegung für Scoringsysteme aller Art ermöglicht. Das entwickelte Konzept garantiert, dass der Kunde ausreichend in die Stärken und Schwächen seiner Bonität Einsicht nehmen kann, ohne gleichzeitig methodisch die Grundlagen multivariater Merkmalsanalysen oder Regressionsmodelle verstehen zu müssen. In einem Beispiel aus dem Bereich des Konsumentenkredit-Scoring wird das Konzept ausgeführt und zeigt eine technische Lösung, so wie sie von Banken jeder Größe implementiert werden kann.
