If they charge a 1% fee to manage funds, they will earn that 1% regardless. Unless they are charging extra fees, it should not increase their earnings beyond that.
If they are charging a yearly 1% fee, a swap won’t affect them unless there are front-end or back-end load fees. If that is the case, you should make a change as soon as possible.
That is simply a terrible advising firm. They most likely hold second registrations as brokers in order to receive kickbacks and commissions on those money.
However, there are also many excellent companies in the field. In addition to charging about 1%, the firm where I work builds out stock and bond portfolios for our clients instead of just placing them in funds. We have also outperformed our benchmarks net of fees.
