OREANDA-NEWS. December 5, 2011. Within the framework of the MICEX and RTS integration process, new versions of the Rules of Sectoral Indices calculation and methodologies for calculation of the RTS Index and the RTS Standard Index were approved.  The Rules are planned to be in effect since December 16, 2011.

The new procedure for calculation of sectoral indices implies that MICEX will use prices generated during the main trading mode to obtain ruble and dollar values of the sectoral indices. Whereby historical values of the MICEX and RTS sectoral indices will serve, respectively, as ruble and dollar historical values for the united sectoral indices.  This document establishes  a unified procedure for drawing up lists of securities employed in the indices calculation, their implementation, information disclosure, determination of the weighting coefficients and free-float factors has been established. In addition, it sets forth a single procedure for unscheduled amendments to be introduced. The constituents lists will be reviewed each quarter and will come into force on the 16th day of the last month in a quarter.

Ruble-denominated sectoral indices will be calculated on the basis of the updated constituent lists as of December 16, 2011, while the calculation of sectoral indices based on dollar-denominated prices will be launched on December 19, 2011.

MICEX also approved the Methodologies for calculating the RTS Index and RTS Standard Index.

The Methodologies were reviewed, due to the transfer of the RTS indices to MICEX. As a result of the move the RTS Index and RTS Standard Index will be calculated in accordance with the documents approved by MICEX using prices from the Standard and Classica markets which will operate within the MICEX structure.  The methodologies provide for a unified approach for determining free-float factors which will be employed for the calculation of all indices of the integrated exchange.

These Methodologies will become effective on December 19, 2011.
