  • US rules regarding offshore accounts

    The Hiring Incentives to Restore Employment Act 2010, enacted on 18 March 2010, imposes a new US withholding tax and reporting regime, known as the Foreign Account Tax Compliance Act (FATCA). The FATCA regime applies generally to payments made after 31 December 2012, except on obligations (to be defined in future guidance) outstanding on 18 March 2012. Substantial effort is required by foreign entities to bring their worldwide operations and policies into compliance with the FATCA rules as of the effective date.

In this context, a wave of draft laws is to be passed and implemented within the following months, amongst which, the Law No. 53.08, setting up a new financial authority, and the Law No. 54.08, reforming public offering rules, are of paramount importance to Moroccan and foreign issuers, and financial institutions.

    The opportunities offered to foreign investors by the Chinese mergers and acquisitions market are increasing every year: in 2010, transactions involving foreign companies came to 60.1 billion euros, an increase of 21.2% compared with 2009. Seen from the West, where markets are declining, all sectors of the Chinese economy seem to be undergoing promising development and the statistics indicate that the Middle Empire will be a lasting springboard for growth.
