Deutsche Bank, Germany\'s biggest bank, said on Tuesday its net profits were halved in the second quarter, as it made massive provisions to meet litigation costs. The bank\'s net profits fell to 335 million euros ($444 million) for the three months ending June, down from 666 million in the second quarter last year. This missed market expectations by a wide margin. Analysts polled by Dow Jones Newswires had forecast about 869 million euros in profits. But 630 million euros set aside by the bank had eaten into its profits for the quarter. Deutsche Bank is currently facing several legal challenges including a case in the Uited States related to subprime mortgages, as well as a tax fraud case linked to the trading of carbon emission permits in Europe. The bank, one of the biggest in Europe, has been making provisions for legal costs, with 600 million euros set aside in the last quarter of 2012. In the second quarter, its revenues were up 2 percent to 8.2 billion euros, according to its earnings report Tuesday.
