U.S. authorities say the shipping company Horizon Lines LLC has agreed to plead guilty to fixing prices and to pay a $45 million fine.

A Justice Department statement Thursday says the company was accused of conspiring to fix rates and surcharges for freight transportation between the United States and Puerto Rico from May 2002 until April 2008.

Five former executives have been sentenced after pleading guilty in 2008 to charges related to the shipping conspiracy.

The Charlotte, North Carolina-based company has a fleet of 20 U.S.-flagged cargo ships that carry items including heavy equipment, medicines and consumer goods.

In June 2009, the company agreed to pay $20 million to settle a class action price-fixing lawsuit.

A former public relations employee has sued Publicis Groupe SA for $100 million, saying the French advertising company discriminates against women in pay and promotions.

Women make up 70 percent of the company's public relations staff but hold only about 15 percent of leadership positions, the lawsuit says.

"A Publicis woman's place is in the back of the line, far removed from senior management positions, almost all of which are reserved for the men," the complaint contends.

The case was filed in U.S. District Court in Manhattan and seeks class-action status. It was filed by Monique da Silva Moore, who was global healthcare director in the Boston office of the company's public relations division MSLGroup.

"We generally do not comment on pending litigation, but we can say that the fact that the Equal Employment Opportunity Commission dismissed Ms da Silva's charge reflects the lack of merit to her claims," a spokeswoman for MSLGroup said.

A measure that would bar Iowa county officials from issuing marriage licenses to same-sex couples faces a bleak future as it sits in a House committee.

Top Republicans on Thursday said they have no plans to debate the issue, viewing it a nod to the party's social conservative wing. Top Democrats argue the measure is unconstitutional and violates a 2009 Iowa Supreme Court decision striking down a state law defining marriage as being between one man and one woman.

Backers say introducing the measure is one more opportunity to voice their displeasure with how the marriage issue has been handled.

Republican Rep. Betty De Boef (dee-BUFF') says the issue has been handled badly and that some lawmakers want to take every opportunity to make that point.
