Frequently Asked Questions

There are two types of shares in the Brazilian market: Common and Preferred.

Common shares are those that confer shareholders the right to participate in a company´s earnings and the right to vote at shareholders´ meetings.

Preferred shares are characterized for having priority upon the distribution of dividends and, in the event the company is dissolved, they have priority in receiving the distribution of its capital. Preferred shares do not confer the right of vote in shareholders´ meetings, except in special situations. In general, a larger percentage is set aside for preferred shares than for common shares for the purpose of the distribution of dividends. Braskem preferred shares are divided into two different classes: Class A (PNA) and Class B (PNB).

Regarding form, shares are nominative or book entry

Braskem chose the book entry form for its shares since the system offers greater safety and convenience for shareholders.

The most important trading market for Braskem's common shares (BRKM3), class A preferred shares (BRKM5) and class B preferred shares (BRKM6) is the São Paulo Stock Exchange, BM&Bovespa. Its common shares and class A preferred shares began traded on the São Paulo Stock Exchange on November 11, 1980. Our class B preferred shares began traded on the São Paulo Stock Exchange on August 19, 1983.

On December 21, 1998, ADSs representing our class preferred shares (BAK) began being traded on The New York Stock Exchange.

On October 8, 2003, Braskem listed its class A preferred shares (XBRK) on the LATIBEX, a stock market for Latin American issuers that is quoted in euros on the Madrid Stock Exchange. Our class A preferred shares are traded on the LATIBEX in unitary lots.

According to the third paragraph of Braskem´s Bylaws, class B preferred shares can be converted into class A preferred shares at any time at a ratio of two class B preferred shares for each class A preferred share.

These rules are designed to increase shareholders´ rights and enhance the quality of information provided by Brazilian corporations.

Earnings may be paid in two ways: dividends or interest on own capital.

The distribution of dividends is conducted on an annual basis, as long as the company has posted profits during the period in question and the balance of the accumulated profit / loss account is positive.

The interest on own capital may be distributed in lesser intervals than on an annual basis.

The dividends may be received through a credit deposit in their bank account, for which the shareholder need only maintain an updated registration of the account data with Banco Itaú, the depositary institution for the Braskem Group´s shares. Earnings will be available to shareholders for a period of 3 (three) years as of the initial date of payment. At the end of this term, the dividends are extinguished and the amounts revert to the company.

An ex-dividend share is that which is acquired after the holding of the shareholders´ meeting that decided about the distribution of dividends. The dividends are credited in favor of the prior shareholder; that is, the one who held the rights to the share upon the date of the meeting, with the rights belonging to those who were shareholders before the meeting.
