Shares of Deutsche Bank are slipping in Monday trading after the bank announced an 8 billion-euro, or nearly $11 billion, capital increase. Deutsche Bank plans to issue 360 million new shares, 60 million of which are being purchased by the royal family of Qatar for about 1.7 billion euros. The bank said it plans to raise another 6.3 billion euros in a rights issue to existing shareholders. The move will increase the bank's Common Equity Tier 1 ratio to 11.8% from 9.5% at the end of the first quarter. The ratio is considered a measure of a bank's ability to withstand stress.
