Senator Quinn raised the issue of non-executive directors and the problems that this section could introduce to the field of foreign direct investment. The committee is mandatory for public limited companies, but not for private companies that meet the thresholds of balance sheet value of €25 million and turnover of €15 million per annum. If those companies do not establish a committee, they have to explain why they have not done so. The compliance statement is not required to be signed by the non-executive directors, but by the directors as a whole.
