I. Analytical Framework, Concepts, Definitions, and Classifications

2.1.1 Concepts and definitions       Main Indices:           LuxX Index Lux General         The LuxX index is a basket index with a twofold computation, ie the price LuxX index and the return LuxX index. The price index is published as of 4 January 1999. The return LuxX index is similar to the price index except that it takes into account the stripped net dividends. In so doing it enables the investors to assess their return on investment. The return index has been published since 31 March 1999.

II. Scope of the data

2.2.1 Scope Scope of the data       The components of the LuxX index are established as follows:               all shares issued by Luxembourg companies listed on the Luxembourg Stock Exchange having directly or indirectly an economic activity in Luxembourg, and whose part of the share-holders is Luxembourg-based are eligible. The Stock Exchange Committee decides on the eligibility in respect of each company by assessing whether both requirements are adequately met;           the shares issued by a foreign company listed on the Luxembourg Stock Exchange and which, on one hand, has acquired a Luxembourg company formerly retained among the LuxX index constituents, and, on the other hand, will continue to have directly or indirectly an economic activity in Luxembourg and whose part of the shareholders will remain Luxembourg-based. The Stock Exchange Committee decides whether for each company the requirements are adequately met;           the LuxX index is an open index, which means that the number of eligible constituent companies is not limited. As a matter of fact, any company meeting the requirements specified in paragraphs above can be retained among the index constituents.           The Lux General index comprises all listed domestic shares. Its basis is 1,000 as at January 4, 1999. The shares of the Lux General Index are weighted on the basis of their market capitalisation, i.e. the total number of issued shares multiplied by the price of the day.

III. Accounting Conventions

2.4.2 Recording basis       The LuxX price index is computed and published in real-time.         The LuxX index is based at 1,000 points on 4 January 1999.

IV. Nature of the Basic Data Sources

3.1.2 Source data definitions, scope, classifications, valuation, and time of recording       The data used for the calculation are prices from the electronic trading system of the Bourse de Luxembourg.

V. Compilation Practices

3.3.2 Other statistical procedures           the weight of the Luxembourg companies in the basket used to calculate the LuxX index is assessed on the basis of their individual free-float market capitalization;         the weight of the foreign companies in the basket used to calculate the LuxX index is assessed on the basis of 15% of their individual free-float market capitalization;         should the weight of a company be on top of  20%, it would be reduced to 20% and the excess would be distributed proportionately between the other index constituent companies. If several companies are subject to a limit of 20%, the Stock Exchange Committee may resolve, on the basis of the actual weight of the companies concerned, to readjust the weight of these companies by applying a scale of +/- 2.50% steps. The sum of the readjusted weights shall be a multiple of 20.         The LuxX index is a basket index. The LuxX index has been constructed in order to be used as a benchmark by the investors and possibly to enable it to be used as an underlying asset for derivatives. To this end the LuxX index relies on a basket of easily tradable securities meeting the requirements defined above. The number of securities included in the basket for a given share is obtained by applying its weight to the basis capitalization of the index basket. The resulting amount is then divided by the last stock exchange price of the month preceding the index update date.               Revision of the index constituents A revision of the LuxX index constituents is made annually by the Stock Exchange Committee in accordance with the procedures set out above. However, the Stock Exchange Committee may proceed to a revision in June in case of substantial variation of at least one of its components.

VI. Other Aspects

5.3.2 Availability of documents and services catalogs       The brochure The Indices of the Luxembourg Stock Exchange published by the Luxembourg Stock Exchange contains the methodology of the indices.
