Sexual abuse by priests has cost the Catholic Church in the United States more than $1 billion, a figure guaranteed to rise - possibly by tens of millions of dollars - because of hundreds of still unsettled claims.

Tallies by American bishops and an Associated Press review of known settlements put the actual pricetag at $1.06 billion.

The money was used by dioceses to pay settlements with victims, legal fees, counseling and other expenses since 1950, the AP found. A $120 million compensation fund announced last week by the Diocese of Covington, Ky., pushed the total past the billion-dollar mark.

At least $378 million has been spent in just the past three years, when the crisis erupted in the Boston Archdiocese and spread nationwide.

The Rev. Thomas Doyle, who left a promising career with the church to help represent victims, had warned the bishops in 1985 that abuse costs eventually could exceed $1 billion.

"Nobody believed us," said Doyle, a canon lawyer. "I remember one archbishop telling me, 'My feeling about this, Tom, is no one's ever going to sue the Catholic Church.'"

Asked about the dollar amount, a spokesman for the U.S. Conference of Catholic Bishops, Monsignor Francis Maniscalco, said church leaders believe the payouts "should be just to all sides." He said victims deserve compensation, but the church also must have enough money to continue serving parishioners.

The bishops are set to meet in Chicago next week to review their plan for protecting youngsters.

The exact financial effect on the church is hard to determine, since each diocese owns property separately and settles cases on its own. Insurance policies cover some costs, but policies differ from diocese to diocese. And in many places, the coverage has run out.

Also, many dioceses already had financial problems because of rising labor costs, maintenance for old churches and other expenses, said Charles Zech, an economics professor at Villanova University who studies church finances.

The church, however, avoided a feared widespread boycott by donors, Zech said. The number of donors has fallen in the past few years, but the amount contributed overall has held steady, he said.

Still, some of the damage is plain.

The Boston Archdiocese and several others have agreed to sell property to cover their multimillion-dollar settlements. Three dioceses - Portland, Tucson, Ariz., and Spokane, Wash. - have filed for bankruptcy, and more are expected to follow.

The billion-dollar cost does not come close to other major legal settlements in recent years. The tobacco industry, for example, has agreed to hundreds of billions of dollars in payouts.

The AP calculated the price from settlement announcements by dioceses and from reports commissioned by the nation's bishops, including a study by the John Jay College of Criminal Justice of claims from 1950 to 2002. Victims' groups believe the church reports have underestimated the total.

Among religious groups confronting abuse, the Catholic Church is the only one to release settlement figures covering decades. But experts believe that Catholics have paid more to victims than any other denomination. Researchers commissioned by the bishops found more than 11,500 abuse claims against priests since 1950.

Catholics disagree over whether the church is being forced to pay too much for its failures.

Barbara Blaine, founder of the Survivors Network of those Abused by Priests, noted that most recent agreements have been reached before trial - a sign, she said, that bishops know the true scope of the wrongdoing and are trying to minimize the cost.

"That the settlements could go that high shows us the seriousness of the harm and the cover-up," Blaine said.

But defense attorneys say public opinion has moved so far against the church that the bishops have little choice.

Several states extended the statutes of limitation for suing over the abuse; California abolished the time restriction for one year, leading to hundreds of new claims that have yet to be resolved.
