Cyn belled bod y Cynulliad yn ei gymeradwyo, rwy'n disgwyl cyhoeddi'r Cod ADY cyn diwedd 2019, a gweithredu'r system ADY newydd dros gyfnod o dair blynedd gan ddechrau ym mis Medi 2020.
Subject to its approval by the Assembly, I expect to publish the ALN Code before the end of 2019, with the new ALN system implemented over a period of three years beginning in September 2020.
