FRANKFURT, Jan. 5 (Xinhua) -- Germany's largest commercial bank Deutsche Bank expected to record a small full-year after-tax loss in 2017, according to its latest estimate released on Friday.

Deutsche Bank has estimated the impacts of U.S. tax reforms on its financial results, concluding that 1.5 billion non-cash tax would be charged in the bank's results for the fourth quarter 2017.

Moreover, the bank expects to report positive operating profit for the full year 2017.

The bank will report preliminary fourth quarter and full year results on Feb. 2.

The reduction in the U.S. federal tax rate from 35 percent to 21 percent is expected to reduce its effective tax rate on average to the lower end, the bank said.

However, the revaluation of U.S. Deferred Tax Assets is expected to reduce the capital ratio of the bank by approximately 10 basis points.
