We don't like percentage methods of merging lists and have never employed it. We do however like ratios by category and status which is essentially how the last three mergers were done. The exception was the NWA merger where category and status were used with the addition of a retirement credit on the NWA side. I would be quite happy if they used the exact same method in a merger with AS. Sadly I believe that merger is going to happen sooner rather then later.
