Mexico’s congress approved a bill to reform the country’s existing stock market law in a bid to spur more debt and equity listings.

The country’s lower house approved the legislation on Wednesday with 452 votes in favor and zero against. The reform aims to make it easier for smaller companies to sell debt or stock to institutional investors by streamlining regulations. It also allows for classes of shares with different voting rights, so-called dual-class shares, to entice family-controlled companies to go public.
