Investment Objective

The Fund seeks to provide total return through a combination of current income and capital appreciation.

Fees and Expenses of the Fund

This table describes the fees and expenses that you pay if you buy, hold and sell shares of the Fund. The table and expense example do not reflect any transaction fees or commissions that may be charged by a shareholder’s financial intermediary when buying or selling shares.

Shareholder Fees (fees paid directly from your investment)

	Investor	Advisor	Institutional
Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)	None	None	None
Exchange Fee	None	None	None
Redemption Fee (as a percentage of amount redeemed or exchanged within 90 days or less)	2.00%	2.00%	2.00%

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

	Investor	Advisor	Institutional
Management Fees	0.68%	0.68%	0.68%
Distribution (12b-1) Fees	None	None	None
Total Other Expenses1	0.27	0.12	0.03
Total Annual Fund Operating Expenses	0.95	0.80	0.71

1 “Other Expenses" include "Acquired Fund Fees and Expenses,” which were less than 0.01% of the average net assets of the Fund. “Acquired Fund Fees and Expenses” are indirect expenses the Fund incurred from the Fund’s investment in one or more money market funds (acquired funds). To the extent that the Fund invests in acquired funds, Total Annual Fund Operating Expenses in the table above may not match the ratios of expenses to average net assets shown in the “Financial Highlights” in the Fund’s prospectus, since the Financial Highlights reflect the operating expenses of the Fund and do not include fees and expenses of acquired funds.

Expense Example

The example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The

example also assumes a 5% return each year, and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	1 Year	3 Years	5 Years	10 Years
Investor	$97	$303	$525	$1,166
Advisor	$82	$255	$444	$990
Institutional	$73	$227	$395	$883

Portfolio Turnover

The Fund incurs transaction costs when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 55.84% of the average value of its portfolio.

Principal Investment Strategies

The Fund seeks to invest in issuers with high quality business models that have compelling risk-adjusted return characteristics. The Fund employs a fundamental investment process to construct a diversified portfolio of attractively valued high yield corporate bonds (often referred to as “junk bonds”) and secured and unsecured loans, including, without limitation, bridge financing, senior and subordinated loans, delayed funding loans and revolving credit facilities, and loan participations and assignments.

The Fund’s investment team’s research process has four primary pillars:

◾

Business Quality—The team uses a variety of sources to understand the resiliency of an issuer’s business model. The team analyzes the general health of the industry in which an issuer operates, the issuer’s competitive position, barriers to entry, the dynamics of industry participants, and the decision-making history of the issuer’s management and, when applicable, financial equity sponsor. As part of the team’s analysis of a company’s business quality, among other factors, the team considers certain environmental, social and governance (“ESG”) factors relating to the company. These ESG factors may include the impact of environmental regulatory change, the use of human, natural and physical resources and corporate governance structures and practices. When the team deems a factor material to the value of a company, the team incorporates it into its decision-making process.

◾

Financial Strength and Flexibility—The team believes that analyzing the history and trend of free cash flow generation is critical to understanding an issuer’s financial health. The team’s financial analysis also considers an issuer’s capital structure, refinancing options, asset or collateral coverage, financial covenants, amortization schedules and overall financial transparency.

◾

Downside Analysis—The team believes that credit instruments by their nature have an asymmetric risk profile. The risk of loss is often greater than the potential for gain, particularly when looking at below investment grade issuers. The team seeks to manage this risk with what it believes to be conservative financial projections that account for industry position, competitive dynamics and positioning within the capital structure.

◾

Value Identification—The team uses multiple metrics to determine the value of an investment opportunity. The team looks for credit improvement potential, relative value within an issuer’s capital structure and against industry peers, catalysts for business improvement and potential value stemming from market or industry dislocations and/or mergers and acquisitions (“M&A”).

Under normal circumstances, the Fund will invest primarily in instruments that are rated, at the time of purchase, below investment grade (below BBB- by Standard & Poor’s Rating Services (“S&P”) or Fitch, Inc. (“Fitch”) or below Baa3 by Moody’s Investors Service, Inc. (“Moody’s”)), or comparably rated by another nationally recognized statistical rating organization (“NRSRO”), or unrated but determined by Artisan Partners to be of comparable quality, commonly known as “junk bonds.” The Fund may invest a significant portion of its assets in high-yield securities that are rated in the lower rating categories by one or more NRSRO (for example, CCC+ or lower by S&P or Fitch or Caa1 or lower by Moody’s) or, if unrated, are determined by Artisan Partners to be of comparable quality. The Fund may invest in debt securities of any maturity.

The Fund may invest without limit in securities and other instruments of US and non-US issuers, including issuers economically tied to “emerging market” countries, securities traded principally outside of the United States, and securities denominated in currencies other than the US dollar. The Fund usually seeks (but is not required) to hedge against the risk of loss resulting from currency fluctuation. The Fund may invest in private placements and other restricted securities (i.e., securities that are purchased in private placements and, accordingly, are subject to restrictions on resale as a matter of contract or under federal securities laws).

In addition to high yield corporate bonds and loans, the Fund also may invest in other corporate fixed income instruments of varying maturities, including fixed-, variable- and floating-rate bonds, debentures, notes, commercial paper and other types of corporate debt instruments across the credit quality spectrum, such as stressed and distressed debt securities.

The Fund may use derivatives for investment, duration management or hedging purposes, or with the purpose or effect of creating investment leverage. The Fund also may invest in debt obligations issued by governments (including, without limitation, obligations issued or guaranteed by the US government) and/or their agencies and instrumentalities.

Summary Prospectus—Artisan Partners Funds

Principal Risks

Like all mutual funds, the Fund takes investment risks and it is possible for you to lose money by investing in the Fund. Investors in the Fund should have a long-term perspective and be able to tolerate potentially sharp declines in value. The Fund’s principal risks include:

◾

Market Risks—Markets may perform poorly and the securities in which the Fund invests may underperform the general securities markets. Securities markets may experience periods of high volatility and reduced liquidity in response to governmental actions, intervention and/or policies, economic or market developments, or other external factors. The value of a company’s securities may rise or fall in response to company, market, economic, political, regulatory or other news.

◾

Active Management Risks—The success of the Fund is dependent on the team’s investment decisions, which are based, in part, on the research process employed by the team. The portfolio securities selected by the team may decline in value or not increase in value when the market indices, including relevant benchmark indices, are rising, in which case the Fund could experience losses regardless of the performance of the market indices. When the team considers ESG factors in its research process, the Fund may forgo certain investment opportunities and underperform funds that do not consider ESG factors.

◾

Debt Securities Risks—The value of a debt security changes in response to various factors, including, for example, market-related factors, such as changes in interest rates or changes in the actual or perceived ability of an issuer to meet its obligations. Investments in debt securities are subject to, among other risks, credit risk, interest rate risk and high yield securities (“junk bond”) risk, as described below.

◾

Credit Risks—An issuer or counterparty may fail to pay its obligations to the Fund when they are due. Financial strength and solvency (or the perceived financial strength or solvency) of an issuer are the primary factors influencing credit risk. Changes in the financial condition of an issuer or counterparty, changes in specific economic, social or political conditions that affect a particular type of security or other instrument or an issuer, and changes in economic, social or political conditions generally can increase the risk of default by an issuer or counterparty, which can affect a security’s or other instrument’s credit quality or value and an issuer’s or counterparty’s ability to pay interest and principal when due. The values of lower quality debt, including loans, tend to be particularly sensitive to these changes.

◾

High Yield Securities (“Junk Bond”) Risks—Fixed income instruments rated below investment grade, or unrated securities that are determined by Artisan Partners to be of comparable quality, are high yield, high risk bonds, commonly known as “junk bonds.” These bonds are predominantly speculative. They are usually issued by companies without long track records of sales and earnings, or by companies with questionable credit strength. These bonds have a higher degree of default risk and may be less liquid than higher-rated bonds. These securities may be subject to greater price volatility due to such factors as specific corporate developments, interest rate sensitivity, negative perceptions of junk bonds generally and less secondary market liquidity. This potential lack of liquidity may make it more difficult for the Fund to accurately value these securities.

◾

Interest Rate Risks—The values of debt instruments held by the Fund generally will fall in response to increases in interest rates. The value of a security with a longer duration will be more sensitive to changes in interest rates than a similar security with a shorter duration. The Fund may be subject to a greater risk of rising interest rates due to the recent period of historically low interest rates. If interest rates rise, repayments of principal on certain debt securities, including loans, may occur at a slower rate than expected and the expected length of repayment of those securities could increase as a result.

◾

Loan Risks—Investments in loans, including floating or adjustable rate loans, are generally subject to the same risks as investments in other types of debt obligations, including, among others, the credit risk of nonpayment of principal and interest. In addition, in many cases loans are subject to the risks associated with below investment grade securities. The Fund may invest in loans made in connection with highly leveraged transactions, which are subject to greater credit and liquidity risks than other types of loans. Although the loans in which the Fund invests may be secured by specific collateral, there can be no assurance that liquidation of such collateral would satisfy the borrower’s obligation in the event of nonpayment of scheduled interest or principal, or that such collateral could be readily liquidated. In the event of the bankruptcy of a borrower, the Fund could experience delays or limitations with respect to its ability to realize the benefits of the collateral securing a loan or could recover nothing of what it is owed on the loan. Uncollateralized (i.e., non-secured) loans are subject to greater risk of loss (i.e., nonpayment) in the event of default than secured loans since they do not afford the Fund recourse to collateral. Investments in loans may be difficult to value and may be illiquid, including due to legal or contractual restrictions on resale. Transactions in many loans settle on a delayed basis, and the Fund may not receive the proceeds from the sale of a loan for a substantial period after the sale. As a result, sale proceeds related to the sale of loans may not be available to make additional investments or meet redemption obligations until a substantial period after the sale of the loans.

◾

Liquidity Risks—Liquidity risk is the risk that the Fund may be unable to sell a portfolio investment at a desirable time or at the value the Fund has placed on the investment. It may be more difficult for the Fund to determine a fair value of an illiquid investment than that of a more liquid comparable investment.

◾

Valuation Risks—The Fund’s investments are valued in accordance with Artisan Partners’ valuation policies. The valuation of any investment involves inherent uncertainty. The value of a security determined in accordance with the valuation policies may differ materially from the value that could have been realized in an actual sale or transfer for a variety of reasons, including the timing of the transaction and liquidity in the market.

◾

Stressed and Distressed Instruments Risks—Investments in the securities of financially stressed or distressed issuers involve substantial risks, including the risk that all or a portion of principal will not be repaid. These securities may present a substantial risk of default or may be

Summary Prospectus—Artisan Partners Funds

in default at the time of investment. The Fund may incur additional expenses to the extent it is required to seek recovery upon a default in the payment of principal or interest on its portfolio holdings. As with any issuer, the team’s judgments about the credit quality of a financially stressed or distressed issuer and the relative value of its securities may prove to be wrong.

◾

Futures Contract Risks—The Fund may enter into futures contracts, in which the Fund agrees to buy or sell a security or other asset on a specified future date at a specified price or rate. There are risks associated with futures contracts, including that the success of such an investment strategy may depend on an ability to predict movements in the prices of individual securities, fluctuations in markets and movements in interest rates; there may be an imperfect or no correlation between the changes in market value of the securities held by the Fund and the prices of futures; there may not be a liquid secondary market for a futures contract; trading restrictions or limitations may be imposed by an exchange; and government regulations may restrict trading in futures contracts.

◾

Counterparty Risks—The Fund will be subject to credit risk with respect to the counterparties to the derivative contracts and other instruments entered into by the Fund. If a counterparty becomes bankrupt or insolvent or otherwise fails to perform its obligations to the Fund due to financial difficulties, the Fund may experience significant losses or delays in obtaining any recovery (including recovery of any collateral it has provided to the counterparty) from the counterparty.

◾

Foreign Investing Risks—Foreign securities may underperform US securities and may be more volatile than US securities. Risks relating to investments in foreign securities and to securities of issuers with significant exposure to foreign markets include currency exchange rate fluctuation; less available public information about the issuers of securities; less stringent regulatory standards; lack of uniform accounting, auditing and financial reporting standards; and country risks, including less liquidity, high inflation rates, unfavorable economic practices, political instability and expropriation and nationalization risks.

◾

Emerging and Developing Markets Risks—Investment risks typically are greater in emerging and less developed markets, including “frontier markets”, which are a subset of emerging markets and less developed markets that, generally, have smaller economies and less mature capital markets. For example, in addition to the risks associated with investments in any foreign country, political, legal and economic structures in these less developed countries may be new and changing rapidly, which may cause instability and greater risk of loss. Their securities markets may be less developed, and securities in those markets are generally more volatile and less liquid than those in the developed markets. Investing in emerging market countries may involve substantial risk due to, among other reasons, limited information; higher brokerage costs; different accounting, auditing and financial reporting standards; less developed legal systems and thinner trading markets as compared to those in developed countries; different clearing and settlement procedures and custodial services; and currency blockages or transfer restrictions. Emerging market countries also are more likely to experience high levels of inflation, deflation or currency devaluations, which could hurt their economies and securities markets. Certain emerging markets also may face other significant internal or external risks, including a heightened risk of war or ethnic, religious or racial conflicts. In addition, governments in many emerging market countries participate to a significant degree in their economies and securities markets, which may impair investment and economic growth of companies in those markets. Such markets may also be heavily reliant on foreign capital and, therefore, vulnerable to capital flight. Such risks may be greater in frontier markets.

◾

Currency Risks—Foreign securities usually are denominated and traded in foreign currencies and the exchange rates between foreign currencies and the US dollar fluctuate continuously. The Fund’s performance will be affected by its direct or indirect exposure to a particular currency due to favorable or unfavorable changes in currency exchange rates relative to the US dollar. The Fund’s direct or indirect exposure to a particular currency may be hedged to mitigate currency volatility or because the Fund believes a currency is overvalued. There can be no guarantee that any hedging activity will be successful. Hedging activity and/or use of forward foreign currency contracts may reduce or limit the opportunity for gain and involves counterparty risk, which is the risk that the contracting party will not fulfill its contractual obligation to deliver the currency contracted for at the agreed upon price to the Fund.

◾

Private Placement and Restricted Securities Risks—In addition to the general risks to which all securities are subject, securities acquired in a private placement generally are subject to strict restrictions on resale, and there may be no liquid secondary market or ready purchaser for such securities, and a liquid secondary market may never develop. Therefore, the Fund may be unable to dispose of such securities when it desires to do so or at a favorable time or price. This potential lack of liquidity may make it more difficult for the Fund to accurately value these securities. Issuers of private placements or other restricted securities may include special purpose vehicles (“SPVs”) that hold underlying assets to which the Fund wants to gain exposure. The Fund may have the right to receive payments only from the SPV, and may not have direct rights against the issuer of the underlying assets. Investors in such SPVs generally pay their share of the SPV’s administrative and other expenses, including management fees.

◾

Leverage Risks—Certain transactions, including, for example, the use of certain derivatives and borrowing money, can result in leverage. Leverage generally has the effect of increasing the amounts of loss or gain the Fund might realize and creates the likelihood of greater volatility of the value of the Fund’s investments. There is risk of loss in excess of invested capital.

◾

Risks of Emphasizing a Region, Country, Sector or Industry—If the Fund has invested a higher percentage of its total assets in a particular region, country, sector or industry, changes affecting that region, country, sector or industry may have a significant impact on the performance of the Fund’s overall portfolio.

◾

Impact of Actions by Other Shareholders—The Fund, like all mutual funds, pools the investments of many investors. Actions by one investor or multiple investors in the Fund may have an adverse effect on the Fund and on other investors. For example, shareholder purchase and redemption activity may affect the per share amount of the Fund’s distributions of its net income and net realized gains, if any, thereby increasing or reducing the tax burden on the Fund’s shareholders subject to income tax who receive Fund distributions.

Summary Prospectus—Artisan Partners Funds

◾

Operational and Cybersecurity Risks—Operational failures, cyber-attacks or other disruptions that affect the Fund’s service providers, the Fund’s counterparties, other market participants or the issuers of securities held by the Fund may adversely affect the Fund and its shareholders, including by causing losses for the Fund or impairing Fund operations.
