Each of these undertakings lasts until 8/31/2016 and may not be terminated during its term without the consent of the Board of Trustees.

Any such repayment must be made within three years after the year in which NBM incurred the expense.falseRisk/Return Detail Data - Neuberger Berman International Equity Fund (Neuberger Berman International Equity Fund, USD $)NoRoundingUnKnownUnKnownUnKnowntruefalsefalseSheethttp://nb.com/20130628/role/DisclosureRiskReturnDetailDataElementsNeubergerBermanInternationalEquityFund142
