| History of SAX Index |
| |
The Slovak share index (SAX) is the official share index of the BSSE. The SAX is a capital-weighted index that compares the market capitalization of a selected set of shares with the market capitalization of the same set of shares as of a given reference day. The SAX index reflects an overall change of assets connected with an investment in shares that are included in the index. This means that, besides fluctuations of prices, the index also includes dividend payments and revenues connected with changes of share capital amount (that is, the difference between current market price and the issue price of new shares).
The initial value of the SAX index - 100 points - refers to September 14, 1993. The index reflects development only on the BSSE, and until June 30, 2001 it was based on average prices stated in the price lists. Effective as from July 1, 2001 the official daily index value is calculated on the base of last prices of shares. |

Fi = correction factor for i-th share
Piact = last price of i-th share as of the given day
Pir = last price of i-th share as of the reference day (September 14, 1993)
Gi = number of shares of i-th company as of the given day |

| The SAX index formula is flexible and allows for participation of various companies in the index, as well as changes in the number of companies, proportional to changes in their tradeability, or in the case of a new company entering the capital market. In the case of a change in the index's structure, the correction factors are set in such a way that the index with the new structure continuously follows the development of the index with the previous structure. |
