European shares edged lower on Monday, with persistent concerns about Greece's debt situation prompting some investors to take profits after recent strong gains, Reuters reported. There were also stock-specific declines. Deutsche Bank fell 4.9 percent as investors doubted whether co-chief executives Anshu Jain and Juergen Fitschen would meet their new targets. The German lender plans to cut 200 billion euros ($217.5 billion) in investment bank assets and exit a tenth of the countries in which it operates as part of a restructuring programme designed to boost earnings and cut risk. The FTSEurofirst 300 index reached its highest level in nearly 15 years earlier this month and is up nearly 20 percent so far this year.
