After decent rally, perhaps time for a pause

NEW YORK (Reuters) - Stocks could struggle to extend their seven-week winning streak as the quarterly earnings period draws to a close and the market bumps into strong technical resistance.

Many analysts say the market could spend the next few weeks consolidating gains that have lifted the benchmark Standard & Poor's 500 <.spx> by 6.6 percent since the start of the year.

The S&P 500 ended up 0.1 percent for the week, recovering from a late sell-off on Friday after a Bloomberg report about slow February sales at Wal-Mart triggered a slide in the retailer's shares. It was the index's seventh week of gains.

Odds of a pullback are increasing, with the market in slightly overbought territory, said Bruce Zaro, chief technical strategist at Delta Global Asset Management in Boston.

"I do suspect the closing of the earnings season will lead to at least a pause and possibly a pullback," Zaro said. The S&P 500 could shave 3 to 5 percent between now and early April, he said.

Fourth-quarter earnings have mostly beaten expectations. Year-over-year profit growth for S&P 500 companies is now estimated at 5.6 percent, up from a January 1 forecast for 2.9 percent growth, and 70 percent of companies are exceeding analyst profit expectations, above the 62 percent long-term average, according to Thomson Reuters data.

On Thursday, Wal-Mart, the world's largest retailer, is due to report results, unofficially closing out the earnings period. Investors will be keen to see its quarterly numbers, especially after the Friday's news report that rattled investors.

The S&P 500 has gained 4.3 percent since Alcoa kicked off the earnings season on January 8.

The approaching March 1 deadline for across-the-board federal budget cuts unless Congress reaches a compromise adds another reason for caution, especially with recent economic data indicating the recovery remains bumpy.

Manufacturing output fell 0.4 percent last month, the Federal Reserve said on Friday, but production in November and December was much stronger than previously thought.

TESTING RESISTANCE

The S&P 500 has been trading near five-year highs, and it notched its highest level since November 2007 this week. But the gains have pushed the benchmark index almost as far as it is likely to go in the near term, with strong resistance hovering around 1,525 and 1,540, one analyst said.

As a result, the index is set to move sideways, said Dave Chojnacki, market technician at Street One Financial in Huntington Valley, Pennsylvania. "We just don't have the volume or the catalyst right now" to go above those levels, he said.

At the same time, other analysts say, the market has not shown significant signs of slowing, including a break below 15- and 30-day moving averages.

Such moves would be needed to show that momentum is slowing or that the market is at risk of a correction, said Todd Salamone, director of research for Schaeffer's Investment Research in Cincinnati, Ohio. The S&P 500's 14-day moving average is at 1,511 while the 30-day is at 1,494. The index closed Friday at 1,519.

Recent M&A activity, including news this week of a merger between American Airlines and US Airways Group , helped provide some strength for the market this week and optimism that more deals may be on the way.

In the coming days, the market will focus on minutes from the latest Federal Reserve meeting, due to be released on Wednesday, which could provide support if they suggest the Fed will remain on its current course of aggressive monetary easing.

The Fed minutes released in January spooked markets a bit when they revealed that some Fed officials thought it would be appropriate to consider ending asset purchases later in 2013. U.S. Treasury yields rose on that news, though market worries about a near-term end to quantitative easing have since faded.

Among other companies expected to report earnings next week are Nordstrom , Hewlett-Packard and Marriott International

Pakistan faces growing anger over sectarian bombings

QUETTA, Pakistan (Reuters) - Pakistan's unpopular government, which is gearing up for elections expected within months, came under fire on Sunday for failing to improve security after a sectarian bombing in the city of Quetta killed 81 people.

The nuclear-armed country's leaders have done little to contain hardline Sunni Muslim groups which have stepped up a campaign of bombings and assassinations of minority Shi'ites.

On Saturday, Lashkar-e-Jhangvi (LeJ), seen as the most ruthless Sunni sectarian group, claimed responsibility for the attack in Quetta, which deepened suspicions among Shi'ites that Pakistan's intelligence agencies were turning a blind eye to the bloodshed or even supporting extremists.

"The terrorist attack on the Hazara Shi'ite community in Quetta is a failure of the intelligence and security forces," Nawab Zulfiqar Ali Magsi, governor of Baluchistan province, said while touring a hospital.

Leaders of the ethnic Shi'ite Hazara community called on the government to take decisive action, and Pakistanis warned that sectarian violence was spiraling out of control.

"The government is responsible for terrorist attacks and killings in the Hazara community because its security forces have not conducted operations against extremist groups," said Aziz Hazara, vice president of the Hazara Democratic Party.

"We are giving the government 48 hours to arrest the culprits involved in the killing of our people and after that we will launch strong protests."

The death toll from Saturday's bombing rose overnight, with most of the casualties in the main bazaar of the town, capital of Baluchistan, near the border with Afghanistan.

Most of the dead were Hazaras. A senior security official said the figure could rise as 20 people were critically wounded.

On Sunday, people searched for survivors under blocks of cement torn off buildings by the blast. A large blood stain could be seen on a wall near the site.

Many shops and bazaars were closed. Relatives of the wounded responded for an appeal for blood made by hospitals.

"The government knows exactly who is doing what and who is behind all this," said Mohammad Imran, a local trader. "If the government wants (to prevent it), no one can take even a kitchen knife into any market."

POVERTY, CORRUPTION, POWER CUTS

Critics say Pakistan's intelligence agencies previously supported groups like LeJ to fight against Indian forces in Kashmir and failed subsequently to control them.

Now Shi'ites in Quetta and other cities say they are under siege. "We have grown tired of picking up the bodies of our loved ones," said Nasir Ali, 45, a government employee. "I have lost three family members so far in such blasts."

LeJ has also said it was behind a bombing last month in Quetta which killed nearly 100 people, one of Pakistan's worst sectarian attacks.

After that incident, Shi'ite leaders called on Pakistan's military to take over security in Quetta and take on the LeJ.

Growing sectarian violence is piling pressure on the U.S.-backed administration, which already faces a Taliban insurgency, to deliver stability.

"This is a case of barbarity and heartlessness. This is happening because we are divided and not supporting each other," said Malik Afzal, a Sunni student.

"Unless we decide to unite, we will continue to get killed. Today they (Shi'ites) have died. Tomorrow we (Sunni Muslims) will die. The next day, others will get killed."

Pakistani intelligence officials say extremist groups, led by LeJ, want to destabilise the nation through sectarian violence and pave the way for a Sunni theocracy.

More than 400 Shi'ites were killed in Pakistan last year, many by hitmen or bombs. Some hardline Shi'ite groups have struck back by killing Sunni clerics.

"If the government cannot give protection to our community then allow us to protect our own," said Ghulam Abbas, 32, a political worker for the Hazara Democratic Party.

The schism between Sunnis and Shi'ites developed after the Prophet Muhammad died in 632 when his followers could not agree on a successor.

Beyoncé's Life Is But a Dream: The Best Moments

TV Watch

By Aaron Parsley

02/16/2013 at 11:05 PM EST

I am ... still singing!

Beyoncé's HBO documentary, Life Is But a Dream, aired Saturday night and it was a 90-minute whirlwind of music, dance and emotion. And though the singer, 31, has been everywhere recently (the Inauguration, the Super Bowl halftime show, Oprah's Next Chapter), the film was full of new and exciting moments. Here are my favorites:

Baby Bey: A home movie of Beyoncé as a little girl playing with bees made my jaw drop. The scene seems to prove what her fans believe: that she was born to be a superstar known as Queen B. I also loved seeing her singing – and being a typical, giggling teenager – with her sister Solange and Kelly Rowland.

The Heartbreak: From her frank discussion of firing her father as a manager to hearing "the saddest song" she's ever written after having miscarriage, the film – which Beyoncé produced and directed herself – had raw, emotional moments.

Mrs. Carter: Life is like a dream for Beyoncé and husband Jay-Z, who surprisingly shared intimate moments together – giddy over her pregnancy, singing Coldplay's "Yellow" to each other, enjoying solitude on a boat in an undisclosed, exotic location. You could feel the love when she toasted him on his birthday.

Blue Ivy: How cute is she?! When Beyoncé and Jay's baby girl, who turned 1 in January, appeared on the screen at the premiere of Life Is But a Dream at New York's Ziegfeld Theater, the crowd gasped and then let out a collective "aww." And I jammed my fingers on the TV screen the first time I watched, trying to pinch those cheeks. Seeing Beyoncé at home with a baby on her hip was a powerful reminder that the fierce superstar is human afterall.

The Music: Of course! Seeing her sing "Listen" with a gorgeously altered ending in a car convinced me of one thing: Beyoncé is definitely not human! I also loved seeing everything that went into her epic Billboard Music Awards performance of "Run the World (Girls)." I just wish I could do that dance. And is it me or does "Resentment" get grittier and angrier every time she performs it?

Praise Beysus and long live the Queen B!

UN warns risk of hepatitis E in S. Sudan grows

GENEVA (AP) — The United Nations says an outbreak of hepatitis E has killed 111 refugees in camps in South Sudan since July, and has become endemic in the region.

U.N. refugee agency spokesman Adrian Edwards says the influx of people to the camps from neighboring Sudan is believed to be one of the factors in the rapid spread of the contagious, life-threatening inflammatory viral disease of the liver.

Edwards said Friday that the camps have been hit by 6,017 cases of hepatitis E, which is spread through contaminated food and water.

He says the largest number of cases and suspected cases is in the Yusuf Batil camp in Upper Nile state, which houses 37,229 refugees fleeing fighting between rebels and the Sudanese government.

G20 defuses talk of "currency war", no accord on debt

MOSCOW (Reuters) - The Group of 20 nations declared on Saturday there would be no 'currency war' and deferred plans to set new debt-cutting targets in an indication of concern about the fragile state of the world economy.

Japan's expansive policies, which have driven down the yen, escaped criticism in a statement thrashed out in Moscow by financial policymakers from the G20, which groups developed and emerging markets and accounts for 90 percent of the world economy.

After late night talks, finance ministers and central bankers agreed on wording closer than expected to a joint statement issued last Tuesday by the Group of Seven rich nations backing market-determined exchange rates.

A draft communique seen by delegates on Friday had steered clear of the G7's call for fiscal and monetary policy not to be targeted at exchange rates but the later version included a G20 commitment to refrain from competitive devaluations and stated monetary policy would be directed at price stability and growth.

"The language has been strengthened since our discussions last night," Canadian Finance Minister Jim Flaherty told reporters. "It's stronger than it was, but it was quite clear last night that everyone around the table wants to avoid any sort of currency disputes."

The communique, seen by Reuters ahead of publication, did not single out Japan for aggressive monetary and fiscal policies that have seen the yen drop 20 percent.

The statement reflected a substantial, but not complete, endorsement of Tuesday's statement by the G7 nations - the United States, Japan, Britain, Canada, France, Germany and Italy.

"We all agreed on the fact that we refuse to enter any currency war," French Finance Minister Pierre Moscovici told reporters.

NO FISCAL TARGETS

The text also contained a commitment to credible medium-term fiscal strategy, but stopped short of setting specific goals.

A debt-cutting pact struck in Toronto in 2010 will expire this year if leaders fail to agree to extend it at a G20 summit of leaders in St Petersburg in September.

"Advanced economies will develop credible medium-term fiscal strategies ... by the St. Petersburg summit," the communique said.

The United States says is on track to meet its Toronto pledge but argues that the pace of future fiscal consolidation must not snuff out demand. Germany and others are pressing for another round of binding debt-cutting goals.

Backing in the communique for the use of domestic monetary policy to support economic recovery reflected the U.S. Federal Reserve's commitment to monetary stimulus through quantitative easing, or QE, to promote recovery and jobs.

QE entails large-scale bond buying -- $85 billion a month in the Fed's case -- that helps economic growth but creates money, much of which has leaked into emerging markets, threatening to destabilize them.

That was offset in the communique by a commitment to minimize "negative spillovers" of the resulting financial flows that emerging markets fear may pump up asset bubbles and ruin their export competitiveness.

"Major developed nations (should) pay attention to their monetary policy spillover," Vice Finance Minister Zhu Guangyao was quoted by state news agency Xinhua as saying in Moscow.

"Major developed countries' implementation of excessively relaxed currency policy has an influence on the world economy."

Russia, this year's chair of the G20, said the group had failed to reach agreement on medium-term budget deficit levels and also expressed concern about ultra-loose policies that it and other big emerging economies say could store up trouble for later.

Finance Minister Anton Siluanov said a rebalancing of global growth required more than an adjustment of exchange rates.

"Structural reforms in all countries, either with a positive or negative balance of payments, should play a bigger role," he said in an address to Saturday's talks, also highlighting the risk of spillover effects from unconventional monetary policy.

The G20 put together a huge financial backstop to halt a market meltdown in 2009 but has failed to reach those heights since. At successive meetings, Germany has pressed the United States and others to do more to tackle their debts. Washington in turn has urged Berlin to do more to increase demand.

On currencies, the G20 text reiterated its commitment last November, to move towards "exchange rate flexibility to reflect underlying fundamentals and avoid persistent exchange rate misalignments".

"The G7 made a very clear statement this week. I think you'll see the G20 echo what was said, and say that currencies should not be used as a tool of competitive devaluation," Britain's finance minister, George Osborne, said in Moscow.

"Countries shouldn't make the mistake of the past of using currencies as a tool of economic warfare."

Exclusive: North Korea tells China of preparations for fresh nuclear test - source

BEIJING (Reuters) - North Korea has told its key ally, China, that it is prepared to stage one or even two more nuclear tests this year in an effort to force the United States into diplomatic talks, said a source with direct knowledge of the message.

Further tests could also be accompanied this year by another rocket launch, said the source, who has direct access to the top levels of government in both Beijing and Pyongyang.

North Korea conducted its third nuclear test on Tuesday, drawing global condemnation and a stern warning from the United States that it was a threat and a provocation.

"It's all ready. A fourth and fifth nuclear test and a rocket launch could be conducted soon, possibly this year," the source said, adding that the fourth nuclear test would be much larger than the third, at an equivalent of 10 kilotons of TNT.

The tests will be undertaken, the source said, unless Washington holds talks with North Korea and abandons its policy of what Pyongyang sees as attempts at regime change.

North Korea also reiterated its long-standing desire for the United States to sign a final peace agreement with it and establish diplomatic relations, he said. North Korea remains technically at war with both the United States and South Korea after the Korean war ended in 1953 with a truce.

In Washington, U.S. State Department spokeswoman Victoria Nuland urged North Korea to "refrain from additional provocative actions that would violate its international obligations" under three different sets of U.N. Security Council resolutions that prohibit nuclear and missile tests.

North Korea "is not going to achieve anything in terms of the health, welfare, safety, future of its own people by these kinds of continued provocative actions. It's just going to lead to more isolation," Nuland told reporters.

The Pentagon also weighed in, calling North Korea's missile and nuclear programs "a threat to U.S. national security and to international peace and security."

"The United States remains vigilant in the face of North Korean provocations and steadfast in our defense commitments to allies in the region," said Pentagon spokeswoman Major Catherine Wilkinson.

Initial estimates of this week's test from South Korea's military put its yield at the equivalent of 6-7 kilotons, although a final assessment of yield and what material was used in the explosion may be weeks away.

North Korea's latest test, its third since 2006, prompted warnings from Washington and others that more sanctions would be imposed on the isolated state. The U.N. Security Council has only just tightened sanctions on Pyongyang after it launched a long-range rocket in December.

Pyongyang is banned under U.N. sanctions from developing missile or nuclear technology after its 2006 and 2009 nuclear tests.

North Korea worked to ready its nuclear test site, about 100 km (60 miles) from its border with China, throughout last year, according to commercially available satellite imagery. The images show that it may have already prepared for at least one more test, beyond Tuesday's subterranean explosion.

"Based on satellite imagery that showed there were the same activities in two tunnels, they have one tunnel left after the latest test," said Kune Y. Suh, a nuclear engineering professor at Seoul National University in South Korea.

Analysis of satellite imagery released on Friday by specialist North Korea website 38North showed activity at a rocket site that appeared to indicate it was being prepared for a launch (http://38north.org/2013/02/tonghae021413/).

NORTH 'NOT AFRAID' OF SANCTIONS

President Barack Obama pledged after this week's nuclear test "to lead the world in taking firm action in response to these threats" and diplomats at the U.N. Security Council have already started discussing potential new sanctions.

North Korea has said the test was a reaction to "U.S. hostility" following its December rocket launch. Critics say the rocket launch was aimed at developing technology for an intercontinental ballistic missile.

"(North) Korea is not afraid of (further) sanctions," the source said. "It is confident agricultural and economic reforms will boost grain harvests this year, reducing its food reliance on China."

North Korea's isolated and small economy has few links with the outside world apart from China, its major trading partner and sole influential diplomatic ally.

China signed up for international sanctions against North Korea after the 2006 and 2009 nuclear tests and for a U.N. Security Council resolution passed in January to condemn the latest rocket launch. However, Beijing has stopped short of abandoning all support for Pyongyang.

Sanctions have so far not discouraged North Korea from pursuing its nuclear ambitions.

"It is like watching the same movie over and over again," said Lee Woo-young, a professor at Seoul's University of North Korean Studies. "The idea that stronger sanctions make North Korea stop developing nuclear programs isn't effective in my view."

The source with ties to Beijing and Pyongyang said China would again support U.N. sanctions. He declined to comment on what level of sanctions Beijing would be willing to endorse.

"When China supported U.N. sanctions ... (North) Korea angrily called China a puppet of the United States," he said. "There will be new sanctions which will be harsh. China is likely to agree to it," he said, without elaborating.

He said however that Beijing would not cut food and fuel supplies to North Korea, a measure it reportedly took after a previous nuclear test.

He said North Korea's actions were a distraction for China's leadership, which was concerned that the escalations could inflame public opinion in China and hasten military build-ups in the region.

The source said he saw little room for compromise under North Korea's youthful new leader, Kim Jong-un. The third Kim to rule North Korea is just 30 years old and took over from his father in December 2011.

He appears to have followed his father, Kim Jong-il, in the "military first" strategy that has pushed North Korea ever closer to a workable nuclear missile at the expense of economic development.

"He is much tougher than his father," the source said.

Microsoft says it has no backup plan if mobile efforts continue to sputter

Microsoft’s (MSFT) mobile operating system finally saw slight growth last quarter after failing to gain any real traction for two years, but it still only accounts for an estimated 3% of the global smartphone market. On the tablet front, its Windows RT operating system has not managed to attract serious attention from vendor partners or consumers. As shaky as Microsoft’s mobile comeback attempt has been, it stands to reason that the company might have a backup plan in the works — especially considering how important the smartphone and tablet spaces are right now. According to Microsoft CFO Peter Klein, however, the company has no “plan B” in place and it isn’t even considering one.

[More from BGR: Flagship HTC One smartphone revealed in leaked photo]

During the annual Goldman Sachs Technology and Internet Conference this week, Reuters asked Klein if Microsoft has new game plan in the works in light of Windows RT and Windows Phone’s muted receptions.

[More from BGR: After using Microsoft’s Surface Pro, going back to the first Surface is agonizing]

“It’s less ‘Plan B’ than how you execute on the current plan,” the executive responded. “We aim to evolve this generation of Windows to make sure we have the right set of experiences at the right price points for all customers.”

When asked to elaborate, Klein noted that Microsoft is working with vendors to go beyond hitting lower price points and ensure that Windows RT and Windows 8 succeed on a wide range of devices, thus strengthening the Windows ecosystem and making its mobile offering more appealing.

“It’s probably more nuanced than just you lower prices or raise prices,” Klein said. “It’s less a Plan B and more, how do you tweak your plan, how do you bring these things to market to make sure you have the right offerings at the right price points?”

Molly Sims: I Nursed a Little Vampire!

Mom & Babies
Celebrity Baby Blog

02/15/2013 at 01:00 PM ET

Following the birth of her baby boy, Molly Sims was ready to sink her teeth into breastfeeding.

The only problem? Her son Brooks Alan had beaten her to it.

“Early on in the hospital, they really want you to breastfeed, so I’m trying everything,” the model mama, 39, shared during a Wednesday appearance on Anderson Live.

“And I’m like, ‘Gosh, this really, really hurts.’ And they’re like, ‘Oh, we know.’”

Determined to find the root of the pain, Sims went searching in her newborn’s mouth — and was shocked at her discovery.

“I’m like, ‘Is there any way a baby could be born with a tooth?’” she recalls. “And they went, ‘Oh sweetie, I know you’re a model, but … babies aren’t born with teeth!’”

She continues: “Come to find out, my baby was born with a tooth!”

Courtesy ANDERSON LIVE

Despite countless attempts to successfully nurse — “I did nipple shields, nipple guards, supplemental nursing system, it was horrible,” the new mom says — Sims eventually decided to call it quits.

“He was literally like a vampire on me for three months — it was unbelievable,” she says with a laugh. “Cut to I’m not breastfeeding and I’m proud of it.”

Now Brooks, 7 months, has moved on to other milestones — including crawling — and is already taking after his dad, Scott Stuber.

“He has the hairline of my husband. It’s like an Eddie Munster kind of hairline. It’s not so attractive, but [he'll] end up growing into it,” Sims says.

Study: Fish in drug-tainted water suffer reaction

BOSTON (AP) — What happens to fish that swim in waters tainted by traces of drugs that people take? When it's an anti-anxiety drug, they become hyper, anti-social and aggressive, a study found. They even get the munchies.

It may sound funny, but it could threaten the fish population and upset the delicate dynamics of the marine environment, scientists say.

The findings, published online Thursday in the journal Science, add to the mounting evidence that minuscule amounts of medicines in rivers and streams can alter the biology and behavior of fish and other marine animals.

"I think people are starting to understand that pharmaceuticals are environmental contaminants," said Dana Kolpin, a researcher for the U.S. Geological Survey who is familiar with the study.

Calling their results alarming, the Swedish researchers who did the study suspect the little drugged fish could become easier targets for bigger fish because they are more likely to venture alone into unfamiliar places.

"We know that in a predator-prey relation, increased boldness and activity combined with decreased sociality ... means you're going to be somebody's lunch quite soon," said Gregory Moller, a toxicologist at the University of Idaho and Washington State University. "It removes the natural balance."

Researchers around the world have been taking a close look at the effects of pharmaceuticals in extremely low concentrations, measured in parts per billion. Such drugs have turned up in waterways in Europe, the U.S. and elsewhere over the past decade.

They come mostly from humans and farm animals; the drugs pass through their bodies in unmetabolized form. These drug traces are then piped to water treatment plants, which are not designed to remove them from the cleaned water that flows back into streams and rivers.

The Associated Press first reported in 2008 that the drinking water of at least 51 million Americans carries low concentrations of many common drugs. The findings were based on questionnaires sent to water utilities, which reported the presence of antibiotics, sedatives, sex hormones and other drugs.

The news reports led to congressional hearings and legislation, more water testing and more public disclosure. To this day, though, there are no mandatory U.S. limits on pharmaceuticals in waterways.

The research team at Sweden's Umea University used minute concentrations of 2 parts per billion of the anti-anxiety drug oxazepam, similar to concentrations found in real waters. The drug belongs to a widely used class of medicines known as benzodiazepines that includes Valium and Librium.

The team put young wild European perch into an aquarium, exposed them to these highly diluted drugs and then carefully measured feeding, schooling, movement and hiding behavior. They found that drug-exposed fish moved more, fed more aggressively, hid less and tended to school less than unexposed fish. On average, the drugged fish were more than twice as active as the others, researcher Micael Jonsson said. The effects were more pronounced at higher drug concentrations.

"Our first thought is, this is like a person diagnosed with ADHD," said Jonsson, referring to attention deficit-hyperactivity disorder. "They become asocial and more active than they should be."

Tomas Brodin, another member of the research team, called the drug's environmental impact a global problem. "We find these concentrations or close to them all over the world, and it's quite possible or even probable that these behavioral effects are taking place as we speak," he said Thursday in Boston at the annual meeting of the American Association for the Advancement of Science.

Most previous research on trace drugs and marine life has focused on biological changes, such as male fish that take on female characteristics. However, a 2009 study found that tiny concentrations of antidepressants made fathead minnows more vulnerable to predators.

It is not clear exactly how long-term drug exposure, beyond the seven days in this study, would affect real fish in real rivers and streams. The Swedish researchers argue that the drug-induced changes could jeopardize populations of this sport and commercial fish, which lives in both fresh and brackish water.

Water toxins specialist Anne McElroy of Stony Brook University in New York agreed: "These lower chronic exposures that may alter things like animals' mating behavior or its ability to catch food or its ability to avoid being eaten — over time, that could really affect a population."

Another possibility, the researchers said, is that more aggressive feeding by the perch on zooplankton could reduce the numbers of these tiny creatures. Since zooplankton feed on algae, a drop in their numbers could allow algae to grow unchecked. That, in turn, could choke other marine life.

The Swedish team said it is highly unlikely people would be harmed by eating such drug-exposed fish. Jonsson said a person would have to eat 4 tons of perch to consume the equivalent of a single pill.

Researchers said more work is needed to develop better ways of removing drugs from water at treatment plants. They also said unused drugs should be brought to take-back programs where they exist, instead of being flushed down the toilet. And they called on pharmaceutical companies to work on "greener" drugs that degrade more easily.

Sandoz, one of three companies approved to sell oxazepam in the U.S., "shares society's desire to protect the environment and takes steps to minimize the environmental impact of its products over their life cycle," spokeswoman Julie Masow said in an emailed statement. She provided no details.

Buffett, Brazil's 3G team up for $23 billion Heinz buyout

(Reuters) - Warren Buffett and Brazilian financier Jorge Paulo Lemann are teaming up to buy ketchup maker H.J. Heinz Co for $23.2 billion, in what could be the first step of a wave of mergers for the food and beverage industry.

Analysts and people close to the deal said Heinz could be a good starting point to consolidate similar staple food companies, particularly given the larger ambitions of Lemann's private equity firm 3G Capital.

Including debt assumption, Heinz valued the transaction, which it called the largest in its industry's history, at $28 billion. Buffett's Berkshire Hathaway and 3G will pay $72.50 per share, a 19 percent premium to the stock's previous all-time high.

Heinz shares initially rose slightly above the offer price, although Buffett cautioned he had no intention of raising his bid and the stock fell back below that mark by midday. The stock has been on a tear, almost doubling over the last four years, though analysts said the price seemed fair.

They also said the deal could be the first step in a broader wave of mergers for the food and beverage industry.

"Maybe for the consumer staples group in general this may start some talk about consolidation. Even corporate entities are flush with cash, interest rates are low, it would seemingly make sense," Edward Jones analyst Jack Russo said.

Companies like General Mills and Campbell Soup - itself long seen as a potential Heinz merge partner - rose on the news.

Any acquisition could help Heinz further diversify and broaden its international profile. It already dominates the ketchup business, with a nearly 26 percent share of the global market and a 59 percent share domestically, according to Euromonitor International.

The company actually generates the largest portion of its sales in Europe, though its traditional North American consumer products business is the most profitable.

But its real growth engine has been the Asia/Pacific region, where sales increased nearly 11 percent in the last fiscal year, in part on demand for sauces and infant foods in China.

BUFFETT HUNTING GROWTH

The surprise purchase satisfies, at least in part, Buffett's hunt for growth through acquisition. He was frustrated in 2012 by the collapse of at least two unnamed deals in excess of $20 billion and said he might have to do a $30 billion deal this year to help fuel Berkshire's growth engine.

In a regulatory filing late on Thursday, Berkshire said it was providing $12.12 billion in equity, including common stock, warrants and preferred shares with a liquidation preference of $8 billion and a 9 percent dividend.

Barclays Capital's Jay Gelb the deal's valuation appeared high at 19 times Heinz's expected 2014 earnings per share, but that it would enhance Berkshire's consumer portfolio.

Berkshire Hathaway already has a variety of food assets, including Dairy Queen ice cream chain, chocolatier See's Candies and food distributor McLane. Buffett, famed for a love of cheeseburgers, joked he was well acquainted with Heinz's products already and that this was "my kind of deal."

It does represent an unusual teaming of Berkshire with private equity, though; historically, Buffett's purchases have been outright his own. He and 3G founder Jorge Paulo Lemann have known each other for years, and Buffett said Lemann approached him with the Heinz idea in December.

One Berkshire investor said he had mixed feelings about the deal because of the limited growth prospects domestically.

"We're a little hesitant on the staple companies because they don't have any leverage in the United States," said Bill Smead, chief investment officer of Smead Capital Management in Seattle. But at the same time, he said, Buffett was likely willing to accept a bond-like steady return even if it was not necessarily a "home run."

A second investor, Michael Yoshikami of Destination Wealth Management in Walnut Creek, California, said he liked the purchase because it provided cash flow for other deals.

"This is a better use of cash than current money market instruments," said Yoshikami, the firm's CEO and chairman of its investment committee.

3G EXPANDS

For 3G, a little-known firm with Brazilian roots, the purchase is something of a natural complement to its investment in fast-food chain Burger King, which it acquired in late 2010 and in which it still holds a major stake.

Historically, 3G was more of an investor than an acquirer. Its biggest shareholdings include Delphi Automotive, Newell Rubbermaid and Anadarko Petroleum.

Lemann, a globe-trotting financier with Swiss roots, made his money in banking and gained notoriety for helping to pull together the deals that ultimately formed the beer brewing giant AB InBev. Forbes ranks him as the world's 69th-richest billionaire, with a fortune of $12 billion.

3G's Alex Behring runs the fund out of New York. He appeared at a Pittsburgh news conference on Thursday with Heinz management to discuss the deal - and to reassure anxious local crowds that the company will remain based there and will continue to support local philanthropy.

But at the same time, Behring said it was too soon to talk about cost cuts at the company. Unlike Berkshire, which is a hands-off operator, 3G is known for aggressively controlling costs at its operations.

PITTSBURGH ROOTS

Also to be determined is whether CEO Bill Johnson would stay on. Only the fifth chairman in the company's history, Johnson is widely credited with Heinz's recent strong growth.

"I am way too young to retire," he told the news conference, adding that discussions had not yet started with 3G over the details of Heinz's future management.

The company, known for its iconic ketchup bottles, Heinz 57 sauces as well as other brands including Ore-Ida frozen potatoes, has increased net sales for the last eight fiscal years in a row.

Heinz said the transaction would be financed with cash from Berkshire and 3G, debt rollover and debt financing from J.P. Morgan and Wells Fargo. Buffett told CNBC that Berkshire and 3G would be equal equity partners.

That would imply roughly $6 billion to $7 billion of new debt needs to be raised.

Heinz shares soared 19.9 percent, or $12.02, to $72.50 on the New York Stock Exchange.

A week ago the stock hit a long-term high of $61 a share - near records it set in 1998 - having risen almost 5 percent this year and nearly 12 percent since the beginning of 2012.

The Heinz Endowments, a pillar in Pennsylvania philanthropy, said the sale of the company would have virtually no impact on their work. Heinz shares represent just over 1 percent of the endowment's $1.4 billion in holdings.

The deal is also a potential boon for new U.S. Secretary of State John Kerry, whose wife, Teresa, is the widow of H.J. Heinz Co heir John Heinz. Kerry's most recent financial disclosures from his time in the U.S. Senate show a position in Heinz shares of more than $1 million, although the precise size is unclear.

Centerview Partners and BofA Merrill Lynch were financial advisers to Heinz, with Davis Polk & Wardwell LLP the legal adviser. Moelis & Company was financial adviser to the transaction committee of Heinz's board and Wachtell, Lipton, Rosen & Katz served as its legal adviser.

Lazard served as lead financial adviser. J.P. Morgan and Wells Fargo also served as financial advisers to the investment consortium. Kirkland & Ellis LLP was legal adviser to 3G Capital, and Munger, Tolles & Olson LLP was legal adviser to Berkshire Hathaway.
