Chaori Solar, the first company in China to default on a corporate bond, said it would sell assets to repay debt and would try to avoid bankruptcy. The markets took a chilled approach to the solar-equipment company's default, which the authorities may have permitted as a message to investors about pricing risk adequately. China's corporate-bond market has grown rapidly since 2008's credit binge.

UniCredit surprised even the most grizzled observers of Italy's troubled banking industry when it reported a $21 billion net loss for the fourth quarter.

The share price of Herbalife, a U.S. seller of dietary supplements, fell after it said it was being investigated by the Federal Trade Commission. Bill Ackman, an activist investor, has shorted Herbalife's shares; the company rejects his claim that it is a "pyramid scheme."

The banana world was split over the merits of a merger between Chiquita and Fyffes that will create the fruit's biggest distributor. Antitrust regulators will look closely at the deal, especially in Europe, which imposed stiff tariffs on Latin American bananas until 2012. But some say a merger makes sense, given the costs of tackling potentially disastrous diseases in banana crops.

Bank is terminating its planned acquisition of Eddie Bauer, a clothing brand.

Martin Winterkorn, Volkswagen's boss, warned that new technologies being installed in cars could create a "data monster." Smart cars have gadgets that link easily with smartphones, but other features, such as onboard cameras and systems could alert insurers to aggressive-driving patterns, worrying privacy advocates.

Political economy

China's annual rate of inflation slowed to 2 percent in February from 2.5 percent in January, and producer prices continued to decline, providing more evidence of slackening demand in the economy. Chinese exports unexpectedly fell in February, by 18 percent, the most since 2009 and leaving the country with a rare trade deficit. The central bank made further moves to weaken the yuan, possibly to help exporters.

Puerto Rico's $3.5 billion sale of municipal bonds was more than four times oversubscribed, giving the heavily indebted island a few months' breathing room before it risks a default. The junk-rated bonds mature in 2035, and offer investors high yields and tax breaks.
