The BM&FBOVESPA Basic Materials Index (IMAT) is compiled as a weighted average of a theoretical portfolio of stocks pursuant to criteria set forth in this methodology.
The indices compiled by BM&FBOVESPA adopt concepts and practices set forth in the Concepts and Practices Manual for BM&FBOVESPA Indices.
The BM&FBOVESPA IMAT is designed to track changes in the prices of the more actively traded benchmark basic materials stocks, so as to gauge average stock performance specific to the basic materials sector.
The BM&FBOVESPA IMAT is a total return index (see the Concepts and Practices Manual for BM&FBOVESPA Indices).
The BM&FBOVESPA IMAT is composed exclusively of shares and units representing shares of BM&FBOVESPA-listed issuers that meet the inclusion criteria set forth below.
The index universe excludes Brazilian Depositary Receipts (BDRs) and shares of issuers under judicial or extrajudicial reorganization, government- or court-ordered administration or intervention, as well as shares otherwise designated to be under exceptional trading status (see the Concepts and Practices Manual for BM&FBOVESPA Indices).
