Dow Jones & Co. said its profit plunged 85% in the fourth quarter and 32.5% for the year because of a previously disclosed charge related to a currency trading service.

But the publisher of the Wall Street Journal said its operating profit, excluding the one-time charge, climbed 44.4% in the fourth quarter and 5% for the year.

Dow Jones earned $3.5 million, or 3 cents a share, in the three months ended Dec. 31, compared to $23.4 million, or 23 cents a share, a year earlier.

The earnings reflected a $32-million charge associated with Trading Service, a foreign exchange dealing service of its Telerate Inc. subsidiary.

Revenue for the quarter rose 3% to $456.1 million, from $442.9 million a year ago. Operating profit for the quarter rose to $78.7 million from $54.5 million a year earlier.
