    Returns for periods less than one year are not annualized. 

    Past performance does not guarantee and is not a reliable indicator of future results. Investment returns and principal values will fluctuate so that an investor's shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than that shown. Performance may reflect agreements to limit a Fund’s expenses, which would reduce performance if not in effect. The Fund's investments in initial public offerings (IPOs) made a material contribution to the Fund's performance. IPO investments are not an integral component of the Fund's investment process and may not be available in the future.

    International investments involve special risks, including currency fluctuation, lower liquidity, different accounting methods and economic and political systems, and higher transaction costs. These risks typically are greater in emerging markets.  Securities of small- and medium-sized companies tend to have a shorter history of operations, be more volatile and less liquid and may have underperformed securities of large companies during some periods.  Growth securities may underperform other asset types during a given period.  These risks are discussed in the prospectus. Please read it carefully before you invest or send money. 

    Performance Source: Artisan Partners/MSCI. Data & Statistics Sources: Artisan Partners/FactSet/MSCI/GICS. Sector exposure percentages reflect sector designations as currently classified by GICS. Portfolio turnover is reported as of the Fund’s fiscal year end. Artisan Partners may exclude outliers when calculating portfolio statistics. If information is unavailable for a particular security Artisan may use data from a related security to calculate portfolio statistics. For the purpose of determining the Fund's holdings, securities of the same issuer are aggregated to determine the weight in the Fund. Totals may not sum due to rounding. 

    Median  is the data's midpoint value.  Market Cap  is the aggregate value of all of a company's outstanding equity securities. Weighted Average  is the average of values weighted to the data set's composition. Weighted Harmonic Average is a calculation of weighted average commonly used for rates or ratios. Price-to-Earnings Ratio (P/E Ratio) measures how expensive a stock is. Earnings figures used for FY1 and FY2 are estimates for the current and next unreported fiscal years. LT EPS Growth Rate is the average of the 3-5 year forecasted EPS growth rate of a company. Return on Equity (ROE) is a profitability ratio that measures the amount of net income returned as a percentage of shareholders equity. Active Share is defined as the percentage of a portfolio that differs from its benchmark index. Active Share can range from 0% for an index fund that perfectly mirrors its benchmark to 100% for a portfolio with no overlap with an index. Portfolio Turnover  is a measure of the trading activity in an investment portfolio—how often securities are bought and sold by a portfolio.

    MSCI All Country World Index measures the performance of developed and emerging markets. The index(es) are unmanaged; include net reinvested dividends; do not reflect fees or expenses; and are not available for direct investment.

    The Morningstar RatingTM for funds, or "star rating", is calculated for managed products (including mutual funds, variable annuity and variable life subaccounts, exchange-traded funds, closed-end funds, and separate accounts) with at least a three-year history. Exchange-traded funds and open-ended mutual funds are considered a single population for comparative purposes. It is calculated based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a managed product's monthly excess performance, placing more emphasis on downward variations and rewarding consistent performance. The top 10% of products in each product category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars, and the bottom 10% receive 1 star. The Overall Morningstar Rating for a managed product is derived from a weighted average of the performance figures associated with its three-, five-, and 10-year (if applicable) Morningstar Rating metrics. The weights are: 100% three-year rating for 36-59 months of total returns, 60% five-year rating/40% three-year rating for 60-119 months of total returns, and 50% 10-year rating/30% five-year rating/20% three-year rating for 120 or more months of total returns. While the 10-year overall star rating formula seems to give the most weight to the 10-year period, the most recent three-year period actually has the greatest impact because it is included in all three rating periods. 

    The Morningstar Analyst Rating is not a credit or risk rating. It is a subjective evaluation performed by the mutual fund analysts of Morningstar, Inc. Morningstar evaluates funds based on five key pillars, which are process, performance, people, parent, and price. Morningstar's analysts use this five pillar evaluation to identify funds they believe are more likely to outperform over the long term on a risk-adjusted basis. Analysts consider quantitative and qualitative factors in their research, and the weighting of each pillar may vary. The Analyst Rating ultimately reflects the analyst's overall assessment and is overseen by Morningstar's Analyst Rating Committee. The approach serves not as a formula but as a framework to ensure consistency across Morningstar's global coverage universe.

    The Analyst Rating scale ranges from Gold to Negative, with Gold being the highest rating and Negative being the lowest rating. A fund with a "Gold" rating distinguishes itself across the five pillars and has garnered the analysts' highest level of conviction. A fund with a 'Silver' rating has notable advantages across several, but perhaps not all, of the five pillars-strengths that give the analysts a high level of conviction. A "Bronze"-rated fund has advantages that outweigh the disadvantages across the five pillars, with sufficient level of analyst conviction to warrant a positive rating. A fund with a 'Neutral' rating isn't seriously flawed across the five pillars, nor does it distinguish itself very positively. A "Negative" rated fund is flawed in at least one if not more pillars and is considered an inferior offering to its peers. Analyst Ratings are reevaluated at least every 14 months.
