(8)On 29 March 2016, the Commission notified the Joint Committee of the ESAs of its intention to endorse the draft implementing technical standards with amendments in order to ensure a balance between a solid prudential approach and the need to avoid further concentration in an already very concentrated credit rating market dominated by three large ECAIs with a combined market share of around 90 %. In its notification, the Commission highlighted in particular the need to avoid the automatic application after three years of a more conservative mapping to all ECAIs which did not produce sufficient ratings and irrespective of the quality of their ratings, as this approach would risk creating a regulatory barrier to market entry and undermine the competitive position of smaller/newer ECAIs simply because they do not produce as many ratings as large incumbent firms. In its formal opinion of 12 May 2016, the Joint Committee of the ESAs confirmed its initial position and did not resubmit implementing technical standards amended in a way consistent with the Commission's proposed amendments.
