RISK FACTORS The Issuer believes that the following factors may affect the value of the Notes issued under the Programme. Most of these factors are contingencies which may or may not occur and the Issuer is not in a position to express a view on the likelihood of any such contingency occurring. In addition, factors which are material for the purpose of assessing the market risks associated with Notes issued under the Programme are also described below. The Issuer believes that the factors described below represent the principal risks inherent in investing in Notes issued under the Programme, but the inability of the Issuer to pay interest, principal or other amounts on or in connection with any Notes may occur for other reasons and which may not be considered significant risks by the Issuer based on information currently available to it or which it may not currently be able to anticipate. Prospective investors should also read the detailed information set out elsewhere in this Base Prospectus and reach their own views prior to making any investment decision. Factors that may affect the value of the Notes issued under the Programme Investment considerations Relating to the business of Fortis Banque Luxembourg S.A. As part of the financial services industry, the Issuer faces substantial competitive pressures which could adversely affect the Issuer s results of operations. There is substantial competition in Luxembourg and the other regions in which the Issuer does business for the types of banking and other products and services which the Issuer provides. As a result, the Issuer s strategy is to maintain customer loyalty and retention which can be influenced by a number of factors, including service levels, the prices and attributes of products and services, financial strength and claims-paying ratings and actions taken by competitors. If the Issuer is unable to compete with attractive product and service offerings that are profitable, the Issuer may lose market share or incur losses on some or all activities. Competition in the financial services industry is affected by the high level of consolidation, both at a national and an international level, in the markets in which the Issuer operates as well as the emergence of alternative distribution channels for many of the products the Issuer offers. Consumer demand, technological changes, regulatory actions and other factors also affect competition. The implementation of the euro also resulted in increased cross-border competition. Competitive pressures could result in increased pricing pressures on a number of the Issuer s products and services, particularly as competitors seek to win market share, and may harm the Issuer s ability to maintain or increase profitability. Market conditions can adversely affect the Issuer s results. The Issuer s business segments are affected by market conditions, which can cause results to fluctuate from year to year as well as on a long-term basis. These conditions include economic cycles such as financial market cycles, including volatile movements in market prices, and banking industry cycles. Fluctuations in interest rates and exchange rates, monetary policy, consumer and business spending and demographics and competitive and other factors also influence the Issuer s performance. As a result of changing market conditions and the influence of financial and industry cycles, the Issuer s results of operations are subject to volatility that may be outside the control of the Issuer. In particular, the Issuer s merchant banking activities income and profit or loss before taxation may vary significantly from year to year depending on market conditions. Market risk can adversely affect the Issuer s banking activities. Market risk can negatively affect the Issuer s merchant banking activities. Market risk is the risk of losses due to sharp fluctuations on the financial markets in share prices, interest rates, exchange rates or property prices. These fluctuations also create risks which impact on the structural positions of the banking activities and on the trading positions taken by the banking business (trading risk). In the banking activities, the fixed-rate period of the assets is longer than that of the liabilities, since banks traditionally receive funds in the shorter term and reinvest them for the longer term. As a result, an upward 12

movement in the yield curve on the capital market will lead to a more pronounced fall in the value of the assets than in the value of the liabilities. This also has the effect of reducing the value of the Issuer (which is after all the difference between its assets and liabilities). A movement in the opposite direction naturally increases the Issuer s value. A decline in the stock or bond markets would adversely affect investments, could reduce market liquidity, and could reduce the popularity of products linked to financial assets. Market downturns and high volatility can occur not only as a result of purely economic factors, but also as a result of war, acts of terrorism, natural disasters, or other similar events. As mentioned above, the results of the Issuer s banking operations are also affected by its management of interest rate sensitivity. Interest rate sensitivity refers to the relationship between changes in market interest rates and changes in net interest income. The composition of the Issuer s banking assets and liabilities, and any gap position resulting from the composition, causes the banking operations net interest income to vary with changes in interest rates. In addition, variations in interest rate sensitivity may exist within the repricing periods or between the different currencies in which the Issuer s holds interest rate positions. A mismatch of interest-earning assets and interest-bearing liabilities in any given period may, in the event of changes in interest rates, have a material effect on the financial condition or result from operations of the Issuer s banking business. Asset illiquidity can adversely affect the Issuer s business. Liquidity risk is inherent in much of the Issuer s business. Each asset purchased and liability sold has liquidity characteristics that are unique. Some liabilities are surrenderable while some assets have low liquidity such as privately placed loans, mortgages loans, real estate and limited partnership interests. Additionally, protracted market declines can reduce the liquidity of markets that are typically liquid. If, in the course of its insurance or other activities, the Issuer requires significant amounts of cash on short notice in excess of anticipated cash requirements, the Issuer may have difficulty selling these investments at attractive prices, in a timely manner, or both. While the Issuer manages its operational risks, these risks remain an inherent part of all of its businesses. The operational risks that the Issuer faces include the possibility of inadequate or failed internal or external processes or systems, human error, regulatory breaches, employee misconduct or external events such as fraud. These events can potentially result in financial loss as well as harm to the Issuer s reputation. Additionally, the loss of key personnel could adversely affect the Issuer s operations and results. The Issuer s business inherently generates operational risks. The business is dependent on processing a large number of complex transactions across numerous and diverse products, and is subject to a number of different legal and regulatory regimes. Additionally, because of the long-term nature of much of the Issuer s business, accurate records have to be maintained for significant periods. The Issuer attempts to keep operational risks at appropriate levels by maintaining a sound and well controlled environment in light of the characteristics of its business, the markets and the regulatory environments in which it operates. While these control measures mitigate operational risks they do not eliminate them. The Issuer has significant counterparty risk exposure. The Issuer is subject to general credit risks, including credit risks of borrowers. Third parties that owe the Issuer money, securities or other assets may not pay or perform under their obligations. These parties include borrowers under loans made, the issuers whose securities the Issuer holds, customers, trading counterparties, counterparties under swaps and credit and other derivative contracts, clearing agents, exchanges, clearing houses and other financial intermediaries. These parties may default on their obligations to the Issuer due to bankruptcy, lack of liquidity, downturns in the economy or real estate values, operational failure or other reasons. Catastrophic events, terrorist attacks and other acts of war could have a negative impact on the Issuer s business and results. Catastrophic events, terrorist attacks, other acts of war or hostility, and responses to those acts may create economic and political uncertainties, which could have a negative impact on economic conditions in the regions in which the Issuer operates and, more specifically, on the business and results of the Issuer in ways that cannot be predicted. 13
