In a press statement, the firm says, "UBS issued a press release announcing its financial results for the third quarter of 2007. In the days following this announcement, the price of UBS stock declined to as low as $49.27 per share. Then, on December 10, 2007, UBS announced writedowns of around $10 billion as a result of its subprime mortgage related positions. Following this announcement, the price of UBS stock declined to $48.78 per share, a 26% decline from the Class Period high."

Moe Gibbs, 35, pleaded guilty to six felony counts involving five inmates at the Barnes County Jail.

Last month, a jury found him guilty in the death of Valley City State University Mindy Morgenstern. His first murder trial on the charge, in July in Minot, ended in a deadlocked jury.

Defense attorney Ross Brandborg would not say why Gibbs changed his pleas to guilty. The plea deal calls for a 25-year prison sentence with 10 years suspended.

Prosecutor Jonathan Byers Byers said Gibbs' "acceptance of responsibility" figured into the lower sentence. "There has to be some benefit to him for doing that," Byers said.

Authorities say the assaults took place from May to September last year. Under questioning from Byers on Friday, Gibbs said he had sexual contact with two inmates while they were either asleep or waking up.

The judge agreed to Brandborg's request to delay sentencing on the assault charges. Gibbs is to be sentenced on the murder conviction Monday and for a 2004 rape next Thursday.

Denison first tried to log into the ISO's computer system, but was unsuccessful because his computer privileges had been suspended, investigators said. Denison broke a glass cover that protected an emergency shut-off button, meant for use in case of fire or other calamity, according to the release.

Denison allegedly went home after shutting off the power to the computers, and told a friend the next morning that he had pressed the emergency button and had tried to "shut off the power grid," according to prosecutors.

The ISO manages high-voltage lines owned by Pacific Gas and Electric Co., Southern California Edison and San Diego Gas & Electric Co. The April 15 outage disrupted CalISO communications for about two hours, leaving the grid vulnerable to electricity shortages. The ISO used back-up systems to reconnect to the energy market.

Denison is scheduled to be sentenced by U.S. District Judge Garland E. Burrell Jr. at 9 a.m. on Feb. 29. The maximum penalty for attempting to damage an energy facility is five years imprisonment, a $250,000 fine and a three-year term of supervised release. Denison originally had also been charged with making a bomb threat.

The case was investigated by the Federal Bureau of Investigations's Joint Terrorism Task Force, composed of federal, state and local law enforcement agencies.

Kevin James, 31, and Levar Haley Washington, 28, entered their pleas in separate appearances before U.S. District Court Judge Cormac J. Carney. Washington also pleaded guilty to using a firearm to further the conspiracy. Prosecutors said he used a shotgun to rob a Torrance gas station on July 4, 2005.

James faces up to 20 years in prison when he is sentenced March 31. Washington faces up to 20 years in prison on the conspiracy charge and five years to life for the firearms offense when he is sentenced April 28.

Authorities say James, Washington and two others were part of a California prison gang cell of radical Muslims that planned the attacks in the Los Angeles area.

"Homegrown terrorism remains a grave concern to the security of our country, and this cell was closer to going operational at the time than anyone since 9/11," Los Angeles Deputy Police Chief Michael Downing told reporters at a news conference after the two men entered their pleas.

Police uncovered the plot in July 2005 while investigating a string of gas station robberies that authorities say were committed to finance the attacks. Torrance Police Chief John Neu told reporters at the news conference that authorities linked about 10 holdups to the plot.

The plotters were within weeks of being able to carry out an attack, officials said, when they were discovered about two months before the Jewish holiday Yom Kippur.

Washington and James, who arrived in court in chains and prison jumpsuits, said little during their separate hearings. Both men wore goatees and Washington's face was covered in tattoos.

Washington's attorney, Ellen Barry, said outside court that her client decided it was "in his best interests" to plead guilty. James' attorney, Robert Carlin, declined to comment.

Also indicted in the case were Gregory Vernon Patterson and Hammad Riaz Samana. All but Samana, a Pakistani national, are American-born Muslim converts.

Patterson and Samana are charged with conspiracy to levy war against the U.S. government through terrorism, conspiracy to possess and discharge firearms in a violent crime, conspiracy to kill members of the U.S. government uniformed services and conspiracy to kill foreign officials. Patterson is also charged with a robbery count and using a firearm in a violent crime.

U.S. Attorney Thomas O'Brien said Samana has been declared mentally unfit to stand trial and is undergoing psychiatric care at a federal prison facility. Patterson is expected to plead guilty to a terrorism conspiracy charge on Monday.

Prosecutors say the plot was orchestrated by Washington, Patterson and Samana at the behest of James, a California State Prison, Sacramento, inmate who founded the radical group Jamiyyat Ul-Islam Is-Saheeh, or JIS.

Court of Criminal Appeals Presiding Judge Sharon Keller contends that while she ordered the clerk's office closed promptly at 5 p.m., state law clearly gave attorneys for death row inmate Michael Wayne Richard the power to contact judges on the court directly.

In papers filed in U.S. district court in Austin, Keller said Richard's lawyers made no attempt to contact any judges on the court, even though three were available Sept. 25, the date of Richard's execution in 1986 rape and murder of Marguerite Dixon, a Houston-area mother of seven. Keller said the clerk's office was closed but the court's building remained open.

Richard's lawyers were in Houston. The court is in Austin.

Keller has garnered national attention for refusing to extend the court's closing time prior to Richard's execution, despite calls from Richard's attorneys alerting her office they were experiencing computer problems and begging for extra time. But in a motion, Keller said Texas law "provides a clear and unambiguous avenue for litigants to file documents with the (Court of Criminal Appeals) directly through any of its judges, so Richard did not need the CCA clerk's office to stay open after hours to file his motion."

This is the first time Keller has claimed Richard's lawyers could have directly gone to other judges on the court. She previously has tried to shift blame to Richard's lawyers by saying they had all day to file.

Jim Harrington, director of the Texas Civil Rights Project, called Keller's argument "shameless."

"Everyone knows that the key is the clerk's office," said Harrington, whose office is representing Richard's daughter, Doreen Anderson, as well as other attorneys who have filed complaints against Keller for her handling of the appeal.

"The clerks are the ones who intercept the calls, who say 'it's shut down,' " Harrington said. "The rules of procedure in the law are supposed to serve justice and here you have a case where a guy's life is at stake. It's literally a matter of life or death and to fall back on some off-the-wall assertion, 'go find a judge and file it that way' is absurd. It makes a farce of the law."

American Tower Corp. said Thursday that it will pay $14 million to settle a consolidated securities class action filed against the company in May 2006 that concerns its historical stock option granting practices and related accounting.

The broadcast and communications tower operator said that under the settlement, claims against the company will dismissed.

American Tower said it will continue to communicate with its insurers about the insurers' contribution to the settlement.

American Tower expects to report an income statement charge for the amount of the settlement, plus certain related legal fees and expenses.
