SUPPLEMENT TO THE CURRENTLY EFFECTIVE SUMMARY PROSPECTUS

Deutsche Enhanced Global Bond Fund

Effective August 1, 2016, the following information replaces the existing disclosure contained under the “AVERAGE ANNUAL TOTAL RETURNS” sub-heading of the “PAST PERFORMANCE” section of the fund’s summary prospectus.

Average Annual Total Returns
(For periods ended 12/31/2015 expressed as a %)

After-tax returns (which are shown only for Class A and would be different for other classes) reflect the historical highest individual federal income tax rates, but do not reflect any state or local taxes. Your actual after-tax returns may be different. After-tax returns are not relevant to shares held in an IRA, 401(k) or other tax-advantaged investment plan.

Barclays Global Aggregate Bond Index (reflects no deduction for fees, expenses or taxes)		-3.15	0.90	3.74

On August 1, 2016, the Barclays Global Aggregate Bond Currency Hedged Index replaced the Barclays Global Aggregate Bond Index as the fund’s comparative broad-based securities market index because the Advisor believes the Barclays Global Aggregate Bond Currency Hedged Index more closely reflects the fund’s investment strategies.
