This is normally published the following Autumn once all financial and performance information have been checked - this is a self evaluation and we try to be as open and honest as we can.
Cyhoeddir hyn fel arfer yn yr hydref, unwaith y bydd yr holl wybodaeth ariannol a pherfformiad wedi'i gwirio - hunanwerthusiad yw hwn ac rydym yn ceisio bod mor agored a gonest ag y gallwn.
