BOSTON (AP) _ Fidelity Investments has sent out revised tax statements to some shareholders in two of its mutual funds following the recent sharp decline in the value of the Mexican peso.

But the revisions have drawn no complaints from the 23,000 shareholders affected, Fidelity says, because it means they owe less in taxes.

``I don't know anyone who wants to pay more taxes,'' Fidelity spokeswoman Marilyn Morrison said Tuesday.

The gaffe involves year-end projections on distributions for Fidelity's Global Bond and Short-Term World Income funds, which were stung by the drop in value of the peso back in December.

Fidelity already had started preparing tax forms based on estimates that were made using just 11 months of data. The estimates usually are accurate, but the unexpected crash in Mexico knocked the numbers out of whack, Morrison said.

``Even though this happened in mid-December and we knew about the problem, compiling all the tax information for our shareholders is such a complex process that we couldn't just switch gears,'' she said.

That would have meant redoing statements for all of Fidelity's 7 million shareholders, since each year-end tax statement covers a client's entire portfolio.

The mutual fund company has mailed revised tax forms to about half the shareholders in the two fixed-income funds. Other shareholders received accurate tax statements.

``It's not unusual. It has happened before,'' said Janet Yuen, of Lipper Analytical Services Inc. in New York.

``Certainly, the less it happens the better it is,'' she said. ``But the fact they come out and told people what happened means they are on top of the situation and are managing the problem.''

Yuen said the year-end revisions represent a much different situation than the $2.6 billion accounting error made on Fidelity's Magellan Fund in December.

Fidelity had projected a year-end distribution of $4.32 a share on Magellan, but wound up withdrawing the payment entirely when the accounting error was realized. An omitted minus sign turned a $1.3 billion loss into a $1.3 billion gain on the spreadsheet.

``In terms of the magnitude of dollars involved, this is not in the same league at all,'' she said.

For the Global Bond fund, the revision means 59 percent _ not 31 percent _ of the distribution should be considered a non-taxable return of capital. Sixty-five percent of the distribution from the Short-Term World Income fund should be considered non-taxable, up from 51 percent.
