"Did you know that one of our mutual funds just changed managers?"

I didn't know, so I took the mail from her, snuck a peak at the open paperwork, and started laughing.

The fund firm that handles my Roth Individual Retirement Account was changing the fund administrator, accountant and transfer agent. My wife had mistakenly assumed that "administrator" and "manager" must be the same thing.

They're not, and while a change in the firms handling a fund's backroom operations is no reason for alarm - especially when compared with a change in money managers - it is worth noting: It means you should make changes in your files.

Back-office changes are routine and common in the fund world, particularly for smaller fund firms looking to negotiate better deals for the basic services they need to run a fund. Few people would ever consider a change in back-room functionaries as a big deal, let alone something to worry about.

Ironically, funds typically are not required to tell you when they change managers - most only notify shareholders in their next regularly scheduled report - but must send out notice when the transfer agent and other backroom functions change. As twisted as that seems - with the important news being hidden and the inconsequential stuff requiring the special mailing - it does highlight why an investor cannot ignore a change in functionaries completely. Investors can stay on in a fund no matter who is in charge, but could have problems making deposits or calling in redemptions if they do not have current information on the transfer agent.

The fund's transfer agent - typically listed in the back of the semiannual report - is the record keeper, processing purchases and redemptions, tracking what you own, issuing statements, calculating tax information, and, generally, handling anything to do with your personal account.

The biggest fund firms act as their own transfer agent, rather than farming out the work. But management companies want transfer agents that can do the job effectively and efficiently, and they will make changes when it helps them hold the line or even lower fund expenses, or when it allows them to offer more services for the same money.

Transfer-agency firms sometimes do everything for the funds, right down to providing the phone reps.

Management does not need your approval to change transfer agents, but it does need to let you in on the switch because it typically means a different address for submitting deposits, and it may mean different numbers to call for information or to process redemptions.

Ideally, the service you receive from the fund will improve when a new transfer agent takes over, but that is not always the case, particularly in the few weeks after the switch as reps from the next agent are getting a handle on their jobs. Ask whether the new agent has services that the old provider was lacking, such as average cost-of-shares record keeping on your statement, cross-reinvestment (where your distribution from one fund is automatically reinvested in a sister issue) and more.

You can help improve the service by throwing out all old envelopes for the fund, as sending your money to the old transfer agent will mean at least a two-week delay in getting your money to work, no matter how the firm resolves the problem. You should also make sure that any automatic deposits taken from your bank accounts will continue with the new transfer agent in place, and you should make note of any change in phone numbers so that you have the right information when you want to process a redemption.

Sometimes, after a change in agents, fund firms change your account numbers; if that happens, you will want to make sure your records reflect it.

Your fund's administrator or custodian is a bank or financial institution that actually takes possession of the securities the fund trades, holding them for safekeeping. While the function is critical - because if the management company runs into financial trouble or goes afoul of regulators, the custodian ensures you are not exposed to those losses - the administrator typically has no contact with shareholders, ever. The custodian is protecting your assets, but doesn't deal directly with shareholders anymore than the fund's accountant or auditor.

Unlike a management change, which puts the fund on your "watch list" until new leadership can prove itself, you can toss out the notice of changes in the back room and stop worrying as soon as you have all necessary contact information and know where to look for it. That usually happens with the first account statement after the switch.
