Parnassus Fixed Income Fund

Investor Shares


High level of current income consistent with safety and preservation of capital.


The Parnassus Fixed Income Fund invests in approximately 95 holdings, primarily allocated among government, agency- and non-agency mortgages, and corporate bonds. A top-down view of the economy to assess future interest rates informs the Fund's duration target, which remains similar to that of the benchmark under normal circumstances. The Fund focuses on identifying:

  • Investing primarily in investment grade corporate bonds held in the Parnassus equity funds
  • Securities with superior credit quality that are undervalued
  • Bonds issued by companies with improving cash flows and credit metrics
  • Security analysis incorporates environmental, social, and governance factors

By investing primarily in investment-grade bonds, the Fund provides investors an opportunity for an attractive level of current income consistent with safety and preservation of capital. No derivatives are used in implementing the Fund's strategy.


The Fund’s share price may change daily based on the value of its security holdings. Bond prices are inversely related to interest rates. As interest rates drop, bond prices will increase, and as interest rates go up, the value of bonds will decrease. A security’s value may also be affected by the possibility that issuers of debt obligations will not pay the Fund interest or principal, or that their credit rating may be downgraded by a ratings agency. In addition, up to 20% of the Fund’s total net assets may be invested in convertible securities, which may not have an investment-grade rating. This would make them riskier than securities with an investment-grade rating.

-0.27 % 0.00 %

A measurement of a fund's trailing 36-month returns in relation with the market as a whole. A beta of 1 means that the share price moves exactly inline with the market. A beta over 1 suggests that the share price will typically be more volatile than the market, and conversely, a beta below 1 indicates that the share price will typically be less volatile than the market.

A measurement of how closely the portfolio's performance correlates with the performance of a benchmark index such as the S&P 500.

* Expenses based on total net assets, net of reimbursement.

As described in the Fund's current prospectus dated May 1, 2018, Parnassus Investments has contractually agreed to reduce its investment advisory fee to the extent necessary to limit total operating expenses to 0.68% of net assets for the Parnassus Fixed Income Fund—Investor Shares. This agreement will not be terminated prior to May 1, 2019, and may be continued indefinitely by the investment adviser on a year-to-year basis. The net expense ratio is what investors pay.

2 The Unsubsidized 30-Day SEC Yield is computed under an SEC standardized formula based on net income earned over the past 30 days. It excludes contractual expense reimbursements, resulting in a lower yield.

3 The beta shown for the benchmark is a blended five-year calculation including the Fund’s prior benchmark, Barclays Capital U.S.Government/Credit Bond Index, prior to May 1, 2013 and the current benchmark, Barclays U.S. Aggregate Bond Index thereafter.

The Barclays U.S. Aggregate Bond Index is an unmanaged index of bonds. An individual cannot invest directly in an index. An index reflects no deductions for fees, expenses or taxes, but mutual fund returns do.
