1. Trouble in Germany: Shares in German automakers dropped by about 3% Monday over worries about an investigation into collusion.

European antitrust officials confirmed Saturday that they are investigating claims that the country's major carmakers may have been operating a cartel since the 1990s, colluding on everything from vehicle development and engines, to suppliers and diesel emissions systems.

News of the probe was broken by German news magazine Der Spiegel on Friday. It reported that hundreds of executives from BMW (BMWYY), Mercedes-Benz owner Daimler (DMLRY) and Volkswagen (VLKAY) (plus its subsidiaries Audi and Porsche) had participated in 60 industry working groups.

The motive for the meetings, the magazine reported, was to suspend competition. It cited a letter it said Volkswagen had sent to German antitrust officials last summer in which the world's biggest carmaker admitted to possible anti-competitive behavior.

Volkswagen and Daimler have declined to comment since the news broke Friday.

In a statement on Sunday, BMW said its diesel emissions system differed significantly from others in the market, and none of its vehicles were manipulated to pass emissions tests. A spokesperson declined to comment on the broader cartel allegations.
