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. The Fund has agreed that each of Class A and Class C will repay NBM for fees and expenses waived or reimbursed for the class provided that repayment does not cause annual operating expenses to exceed 1.21% and 1.96% of the class' average net assets, respectively. Any such repayment must be made within three years after the year in which NBM incurred the expense.falseAnnual Fund Operating Expenses Neuberger Berman International Equity FundUnKnownUnKnownUnKnownUnKnownfalsefalsefalseSheet2661026018ColumnperiodPeriod*Columndei_LegalEntityAxisAxisnbef_S000007842MemberColumnrr_ProspectusShareClassAxisAxis*ColumnunitUnit*RowprimaryElement*falseus-types:textBlockItemTypestringContains a command for the SEC Viewer for the role corresponding to OperatingExpensesData.No definition available.false0Annual Fund Operating Expenses [Table]8false 4rr_ExpenseExampleWithRedemptionTableTextBlockrr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalse1falsefalsefalse00~ http://nb.com/20130628/role/ScheduleExpenseExampleTransposed20003 column dei_LegalEntityAxis compact nbef_S000007842Member row primary compact * ~falsefalse~ http://nb.com/20130628/role/ScheduleExpenseExampleTransposed20003 column dei_LegalEntityAxis compact nbef_S000007842Member row primary compact * ~truehttp://nb.com/20130628/role/ScheduleExpenseExampleTransposed20003020003 - Schedule - Expense Example {Transposed}truefalsefalse1falseColumnprimaryElement*3false 4rr_ExpenseExampleYear01rr_falsenadurationfalsefalsefalsefalsefalsefalsefalsefalseterseLabelrr:NonNegativeMonetaryTypemonetaryThe Example assumes that you invest $10,000 in the Fund for the time periods indicated and then you redeem all of your shares at the end of those periods.
