The last two committees were created following reviews by Price Waterhouse Coopers on behalf of the Board of Trustees (March 2015), and Wales Audit Office (February 2016).
Crëwyd y ddau bwyllgor olaf yn sgil adolygiadau gan Price Waterhouse Coopers ar ran Bwrdd yr Ymddiriedolwyr (Mawrth 2015), a Swyddfa Archwilio Cymru (Chwefror 2016).
