The Singapore Exchange will require listed shipping and maritime companies to disclose the exact pay of their chief executives under new rules just unveiled.

Information to be disclosed must include base or fixed salary, variable or performance-related income or bonuses, benefits in kind, stock options granted, share-based incentives and awards, and other long-term incentives.

The SGX has said it will also limit to nine years the tenure of independent directors serving on the boards of listed issuers.
