OREANDA-NEWS. September 22, 2011. BM&FBOVESPA announces the conclusion of the first stage of development and integrated tests with the market of its new trading platform, named the BM&FBOVESPA PUMA Trading System. This is a multi-asset electronic trading platform that has been developed by BM&FBOVESPA and CME Group. BM&FBOVESPA PUMA Trading System will replace the Global Trading System (GTS), Mega Bolsa, BOVESPA FIX and SISBEX, integrating them into a single system with greater processing capacity, extremely low latency, and new functions. The implementation will occur in stages:

1st Stage: Substitution of GTS (derivatives and spot foreign exchange);

2nd Stage: Substitution of Mega Bolsa (equities and equity derivatives);

3rd Stage: Substitution of BOVESPA FIX (fixed-income corporate securities) and SISBEX (government securities).

The Exchange implemented the BM&FBOVESPA PUMA Trading System in the spot foreign exchange market on August 29, 2011. The other stages will be executed in the following weeks, at dates to be announced at an opportune moment. As part of the GTS replacement effort, instruments will migratein four-stages. At each stage, orders sent to the Exchange for these contracts will be processed exclusively by the new system. The migration stages are:

1st Migration: Spot foreign exchange contracts.

2nd Migration: Agricultural derivatives.

3rd Migration: Financial derivatives (interest rates, foreign exchange, inflation indices, gold etc.), except for derivatives based on stock indices.

4th Migration: Derivatives based on stock indices.
