Shareholder Fees (fees paid directly from your investment) Example This 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 you redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return per year and that the Fund's operating expenses remained the same.

If these sales charges (loads) were included, your costs would be higher. Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. 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 __% of the average value of its whole portfolio. Instructions. A.3.instructions.6 New Funds.

However, the Fund may invest up to 20% of its total assets in Municipal Securities that are exempt from Federal income tax, but are subject to the Federal alternative minimum tax.</p><p>Under normal market conditions, the Fund invests at least 75% of its total assets in investment grade bonds, but may invest up to 25% of its total assets in debt securities rated below investment grade (commonly called “junk bonds”). Investment grade debt securities are rated within the four highest grades by at least one of the major rating agencies, such as Standard & Poor’s (at least BBB-), Moody’s (at least Baa3) or Fitch (at least BBB-), or are securities that Payden determines to be of comparable quality.

The following risks could also affect the value of your investment in the Fund:</p><p>As with most bond funds, the income on and value of your shares in the Fund will fluctuate along with interest rates. When interest rates rise, the market prices of the debt securities the Fund owns usually decline. When interest rates fall, the prices of these securities usually increase. Generally, the longer the Fund’s average portfolio maturity, the greater the price fluctuation. The price of any security owned by the Fund may also fall in response to events affecting the issuer of the security, such as its ability to continue to make principal and interest payments, or its credit ratings.</p><p>Investing in the Municipal Securities market involves certain risks. The amount of public information available about Municipal Securities is generally less than that for corporate equities or bonds, and the Fund’s investment performance may therefore be more dependent on Payden’s analytical abilities than if the Fund were to invest in stocks or taxable bonds. The secondary market for Municipal Securities also tends to be less well-developed and less liquid than many other securities markets, which may adversely affect the Fund’s ability to sell its bonds at attractive prices or at prices approximating those at which the Fund currently values them.</p><p>Below investment grade securities (commonly called “junk bonds”) are speculative and involve a greater risk of default and price change due to changes in the issuer’s creditworthiness. The market prices of these debt securities may fluctuate more than the market prices of investment grade debt securities and may decline more significantly in periods of general economic difficulty.</p><p> As a temporary defensive measure, the Fund may also invest up to 20% of its total assets in debt securities that pay interest income subject to Federal income tax.</p><p>The Fund is “non-diversified,” which means that compared with diversified funds, the Fund may invest a greater percentage of its assets in a particular issuer. Accordingly, events that affect a few — or even one — of the Fund’s investments may have a greater impact on the value of the Fund’s shares than they would if the Fund were diversified.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringNarrative Risk Disclosure.
