Abstract

Increased exposure to risk has been an inevitable consequence of recent economic, technological, and financial changes, the defining themes of the 1990s. In the face of such developments, the viability of long-term capital investments - particularly in the core infrastructure sectors of power, transport, and telecommunications - hinges critically on how the risks associated with such investments are evaluated and managed.

Few issues in modern finance have inspired the interest of both practitioners and theoreticians more than risk evaluation and management. The basic principle governing risk management in an infrastructure project finance deal is intuitive and well-articulated: Allocate project-specific risks to parties best able to bear them (taking into account each party's appetite for, and aversion to, risk); control performance risk through incentives; and use market hedging instruments (derivatives) for covering marketwide risks arising from fluctuations in, for instance, interest and exchange rates, among other things.

In practice, however, governments have been asked to provide guarantees for various kinds of projects, often at no charge, because of problems associated with market imperfections:

Derivative markets (swaps, forwards) for currency and interest-rate risk hedging either do not exist or are inadequately developed in most developing countries.

Limited contracting possibilities (because of problems with credibility or enforcement).

Differing methods for risk measurement and evaluation.

Two factors distinguish the financing of infrastructure projects from corporate and traditional limited-recourse project finance: 1) a high concentration of project risk early in the project life cycle (pre-completion), and 2) a risk profile that changes as the project comes to fruition, with a relatively stable cash flow subject to market and regulatory risk once the project is completed. Dailami, Lipkovich, and Van Dyck introduce INFRISK, a computer-based risk-management approach to infrastructure project finance transactions that involve the private sector. Developed in-house in the Economic Development Institute of the World Bank, INFRISK is a guide to practitioners in the field and a training tool for raising awareness and improving expertise in the application of modern risk management techniques.

INFRISK can analyze a project's exposure to a variety of market, credit, and performance risks from the perspective of key contracting parties (project promoter, creditor, and government). Their model is driven by the concept of the project's economic viability. Drawing on recent developments in the literature on project evaluation under uncertainty, INFRISK generates probability distributions for key decision variables, such as a project's net present value, internal rate of return, or capacity to service its debt on time during the life of the project.

Computationally, INFRISK works in conjunction with Microsoft Excel and supports both the construction and the operation phases of a capital investment project. For a particular risk variable of interest (such as the revenue stream, operations and maintenance costs, and construction costs, among others) the program first generates a stream of probability distributions for each year of a project's life through a Monte Carlo simulation technique. One of the key contributions made by INFRISK is to enable the use of a broader set of probability distributions (uniform, normal, beta, and lognormal) in conducting Monte Carlo simulations rather than relying only on the commonly used normal distribution. A user's guide provides instruction on the use of the package.

This paper - a product of the Regulatory Reform and Private Enterprise Division, Economic Development Institute - is part of a larger effort in the institute to address the training needs of Bank client countries as well as support the Bank`s own lending and advisory services in promoting infrastructure development and modernization in developing countries.
