Supplement to Prospectus [Text Block]	rr_SupplementToProspectusTextBlock	DELAWARE GROUP^® EQUITY FUNDS V Delaware Small Cap Core Fund (the “Fund”) Supplement to the current Statutory Prospectus (the “Prospectus”) and Statement of Additional Information (the “SAI”) The Board of Trustees (“Trustees” or “Board”) of Delaware Group Equity Funds V (the “Trust”) approved the appointment of Macquarie Investment Management Global Limited (“MIMGL”) and Macquarie Funds Management Hong Kong Limited (“MFMHKL”) to serve as sub-advisors and provide certain sub-advisory services to the Fund from time to time at the discretion of Delaware Management Company (the “Manager”). In connection therewith, the following replaces the information in the section of the Fund’s Prospectus entitled “Fund summary — What are the Fund’s principal investment strategies?”: The Fund invests primarily in stocks of small companies that its investment manager, Delaware Management Company (Manager), believes have a combination of attractive valuations, growth prospects, and strong cash flows. Under normal circumstances, at least 80% of the Fund’s net assets, plus the amount of any borrowings for investment purposes, will be in investments of small-capitalization companies (80% policy). The Fund considers small-capitalization companies to be companies within the market capitalization range of the Russell 2000® Index at the time of purchase. The Manager may permit its affiliates, Macquarie Investment Management Global Limited (MIMGL) and Macquarie Funds Management Hong Kong Limited, to execute Fund security trades on behalf of the Manager. The Manager may also seek quantitative support from MIMGL. The Fund’s 80% policy is nonfundamental and may be changed without shareholder approval. Fund shareholders would be given at least 60 days’ notice prior to any such change. The following information is added into the section of the Fund’s Prospectus entitled “Fund summary — Who manages the Fund?”: Sub-advisors Macquarie Investment Management Global Limited Macquarie Funds Management Hong Kong Limited The following replaces the information in the section of the Fund's Prospectus entitled "How we manage the Fund — Our principal investment strategies”: The Manager researches individual companies and analyzes economic and market conditions, seeking to identify the securities or market sectors that it believes are the best investments for the Fund. The following are descriptions of how the portfolio management team pursues the Fund’s investment objective. The Manager strives to identify stocks of small companies that it believes offer above-average opportunities for long-term price appreciation based on: (1) attractive valuations, (2) growth prospects, and (3) strong cash flow. The Fund employs bottom-up (stock-by-stock) security selection utilizing quantitative screens, fundamental research, and risk control to evaluate stocks based on both growth and value characteristics. The Manager typically uses a quantitative screen that ranks the attractiveness of an investment based on a combination of valuation measures, earnings expectations, cash flow, and balance-sheet quality. In further evaluating the attractiveness of an investment, the Manager considers factors such as business conditions in the company’s industry and its competitive position in that industry. The Manager conducts fundamental research on certain investments, which often includes reviewing US Securities and Exchange Commission (SEC) filings, examining financial statements, and meeting with top-level company executives. When constructing the portfolio, the Manager applies controls to ensure the portfolio has risk characteristics that it deems acceptable. These characteristics include, but are not limited to, size, valuation, growth, yield, and earnings consistency. This risk profile is then compared to the benchmark index to ensure the portfolio does not have any unintended risk exposure. The Manager may permit its affiliates, Macquarie Investment Management Global Limited (MIMGL) and Macquarie Funds Management Hong Kong Limited, to execute Fund security trades on behalf of the Manager. The Manager may also seek quantitative support from MIMGL. Under normal market conditions, at least 80% of the Fund’s net assets, plus the amount of any borrowings for investment purposes, will be invested in small-cap companies. While the Fund will generally invest primarily in common stock of small-cap companies, from time to time the Fund may also invest in convertible securities, futures contracts, options on futures contracts, and warrants. The Fund will limit investments in non-US securities to 10% of the Fund’s total assets. The Fund’s investment objective is nonfundamental. This means that the Fund’s Board of Trustees (Board) may change the objective without obtaining shareholder approval. If the objective were changed, the Fund would notify shareholders at least 60 days before the change became effective. The following information is added after the section of the Fund’s Prospectus entitled “Who manages the Fund — Investment manager”: Sub-advisors Macquarie Investment Management Global Limited (MIMGL), is located at 50 Martin Place, Sydney, Australia.
