  • The new French regulation applying to national insurance contributions for managers and shareholders

    French insurance contributions on executive and shareholder remuneration (pay + dividends) have been substantially increased by the National Insurance Funding for 2013 Act, No. 2012-1404, of 17th December 2012. Until 31st December 2012, all dividends were subject to national insurance contributions on unearned income but henceforth, under Article L136-3 of the National Insurance Code, amended by Act No. 2012-1404, certain dividends   are considered as pay received by executives and shareholders and are therefore subject to the national insurance contributions on pay. The Act also abolished the ceiling on health insurance contributions payable by the self-employed and all this means that businesses must rethink the way that they have been structured until now.

    The People's Republic of China has initiated an overhaul of its social security system, reformed the personal taxation regime and has extended the scope of these laws to foreigners residing in China.

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.
