Examples.

 The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the noted class of shares for the time periods indicated, your investment has a 5% return each year, and the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, the Examples show what your costs would be based on these assumptions.

Expense Example Institutional, Class P, Administrative, Class D AllianzGI U.S. Managed Volatility Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Institutional	62	195	340	762
P	73	227	395	883
Administrative	88	274	477	1,061
D	98	306	531	1,178

Portfolio Turnover.

 The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The Fund’s portfolio turnover rate for the fiscal year ended June 30, 2013 was 86%. High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Examples above, can adversely affect the Fund’s investment performance.

Principal Investment Strategies

The Fund seeks to achieve its investment objective by normally investing at least 80% of its net assets (plus borrowings made for investment purposes) in equity securities of U.S. companies. The Fund currently defines “U.S. companies” as those companies that (i) are incorporated in the U.S., (ii) derive at least 50% of their revenue or profits from business activities in the U.S. or (iii) maintain at least 50% of their assets in the U.S. The Fund expects to invest typically in companies with market capitalizations at or above the lowest market capitalization of companies represented in the Russell 1000 Index (approximately $487 million as of June 30, 2013). The Fund intends to utilize an investment strategy that focuses on the overall management of portfolio volatility. This focus may result in the Fund outperforming the general securities market during periods of flat or negative market performance, and underperforming the general securities market during periods of strong positive market performance.

The portfolio managers use a dynamic quantitative process combined with a fundamentals-based, actively-managed security selection process to make individual security and sector selection decisions. Under the Sub-Adviser’s managed volatility strategy, the portfolio managers seek to emphasize stocks that exhibit a lower sensitivity to broader market movements (or “beta”), as they believe that stocks with higher betas are not rewarded with commensurately higher returns by the market. The portfolio construction process is iterative in nature. Initially, the portfolio managers build a fully invested and diversified portfolio subject to sector, capitalization and security constraints with a goal of minimizing total volatility as measured by the standard deviation of returns. The team then overlays a proprietary stock selection model and seeks to build a final portfolio of stocks that considers the trade off between volatility and sources of relative performance (or “alpha”). The portfolio managers consider whether to sell a particular security when any of the above factors materially changes, or when a more attractive investment candidate is available.

In addition to equity securities (such as preferred stocks, convertible securities and warrants) and equity-related instruments, the Fund may invest in securities issued in initial public offerings (IPOs), and utilize foreign currency exchange contracts, options, stock index futures contracts, warrants and other derivative instruments. Although the Fund does not expect to invest significantly in derivative instruments during its current fiscal year, it may do so at any time.

Principal Risks

The principal risks of investing in the Fund, which could adversely affect its net asset value, yield and total return, are (in alphabetical order after the first three risks):

Market Risk: The Fund will be affected by factors influencing the U.S. or global economies and securities markets or relevant industries or sectors within them.

Issuer Risk: The Fund will be affected by factors specific to the issuers of securities and other instruments in which the Fund invests, including actual or perceived changes in the financial condition or business prospects of such issuers.

Equity Securities Risk: Equity securities may react more strongly to changes in an issuer’s financial condition or prospects than other securities of the same issuer.

Credit and Counterparty Risk: An issuer or counterparty may default on obligations.

Derivatives Risk: Derivative instruments are complex, have different characteristics than their underlying assets and are subject to additional risks, including leverage, liquidity and valuation.

Focused Investment Risk: Focusing on a limited number of issuers, sectors, industries or geographic regions increases risk and volatility.

IPO Risk: Securities purchased in initial public offerings have no trading history, limited issuer information and increased volatility.

Liquidity Risk: The lack of an active market for investments may cause delay in disposition or force a sale below fair value.

Management Risk: The Fund will be affected by the allocation determinations, investment decisions and techniques of the Fund’s management.

Smaller Company Risk: Securities issued by smaller companies may be more volatile and present increased liquidity risk relative to securities issued by larger companies.

Turnover Risk: High levels of portfolio turnover increase transaction costs and taxes and may lower investment performance.

    Please see “Summary of Principal Risks” in the Fund’s statutory prospectus for a more detailed description of the Fund’s risks. It is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Performance Information

The performance information below provides some indication of the risks of investing in the Fund by showing changes in its total return from year to year and by comparing the Fund’s average annual total returns with those of a broad-based market index and a performance average of similar mutual funds. The bar chart and the information to its right show performance of the Fund’s Institutional Class shares. Class P, Administrative Class and Class D performance would be lower than Institutional Class performance because of the lower expenses paid by Institutional Class shares. For periods prior to the inception date of a share class, performance information shown for such class may be based on the performance of an older class of shares that dates back to the Fund’s inception, as adjusted to reflect certain fees and expenses paid by the newer class. These adjustments generally result in estimated performance results for the newer class that are higher or lower than the actual results of the predecessor class due to differing levels of fees and expenses paid. Details regarding the calculation of the Fund’s class-by-class performance, including a discussion of any performance adjustments, are provided under “Additional Performance Information” in the Fund’s statutory prospectus and SAI. Past performance, before and after taxes, is not necessarily predictive of future performance. Visit us.allianzgi.com for more current performance information. Prior to December 1, 2011, the Fund was managed pursuant to a different investment strategy and would not necessarily have achieved the performance results shown below under its current investment strategy.

    After-tax returns are estimated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts. In some cases the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period. After-tax returns are for Institutional Class shares only. After-tax returns for other share classes will vary.
