Yes, they will merge at the end of the year. Even better, however, is that you can link the accounts today and the combined accrual will take effect as it happens. If you have 40K in UA and 20K on CO and you link the accounts you will get 1P and Gold instead of 2P and nothing. There is a sticky in the PMCO forum and a tread in the PMUA forum though I don't recall if it is a sticky or not with details about the link that provides the linking.
