PRINCIPAL INVESTMENT STRATEGIES AND BENCHMARK

Effective January 23, 2017, all references to the Fund's name in the Prospectus and the SAI are deleted and replaced with the following:

PIMCO Low Duration Income Fund

In addition, effective January 23, 2017, the "Investment Objective" section of the Fund's Fund Summary in the Prospectus is deleted in its entirety and replaced with the following:

The Fund's primary investment objective is to maximize current income. Long-term capital appreciation is a secondary objective.

In addition, effective January 23, 2017, the supervisory and administrative fee for each share class of the Fund, stated as a percentage of the Fund's average daily net assets, will decrease by 0.05%. These supervisory and administrative fee reductions will result in the Management Fees decreasing by 0.05% for each share class of the Fund. In addition, effective January 23, 2017, Pacific Investment Management Company LLC ("PIMCO") has contractually agreed, through July 31, 2018, to reduce its advisory fee by 0.05% of the average daily net assets of the Fund. Accordingly, effective January 23, 2017, in the Prospectus, corresponding changes are made to the Fund's Annual Fund Operating Expenses table and the Expense Examples following the table. Also, effective January 23, 2017, in the Prospectus, corresponding changes are made to the "Management of the Funds—Management Fees—Management Fee," "Management of the Funds—Management Fees—Advisory Fee" and "Management of the Funds—Management Fees—Supervisory and Administrative Fee" sections. In addition, effective January 23, 2017, corresponding changes are made to the "Management of the Trust—Supervisory and Administrative Fee Rates" section of the SAI.

In addition, effective January 23, 2017, the "Principal Investment Strategies" section of the Fund's Fund Summary in the Prospectus is deleted in its entirety and replaced with the following:

The Fund seeks to achieve its investment objective by investing under normal circumstances at least 65% of its total assets in a multi-sector portfolio of Fixed Income Securities of varying maturities, which may be represented by forwards or derivatives such as options, futures contracts or swap agreements. "Fixed Income Instruments" include bonds, debt securities and other similar instruments issued by various U.S. and non-U.S. public- or private-sector entities. The Fund will seek to maintain a high and consistent level of dividend income by investing in a broad array of fixed income sectors and utilizing income efficient implementation strategies. The capital appreciation sought by the Fund generally arises from decreases in interest rates or improving credit fundamentals for a particular sector or security.

The Fund will generally allocate its assets among several investment sectors, without limitation, which may include: (i) high yield securities ("junk bonds") and investment grade corporate bonds of issuers located in the United States and non-U.S. countries, including emerging market countries; (ii) fixed income securities issued by U.S. and non-U.S. governments (including emerging market governments), their agencies and instrumentalities; (iii) mortgage-related and other asset backed securities; and (iv) foreign currencies, including those of emerging market countries. However, the Fund is not required to gain exposure to any one investment sector, and the Fund's exposure to any one investment sector will vary over time. The average portfolio duration of this Fund normally varies from zero to three years based on Pacific Investment Management Company LLC's ("PIMCO") forecast for interest rates. Duration is a measure used to determine the sensitivity of a security's price to changes in interest rates. The longer a security's duration, the more sensitive it will be to changes in interest rates.

The Fund may invest up to 30% of its total assets in high yield securities rated below investment grade but rated at least Caa by Moody's Investors Service, Inc. ("Moody's"), or equivalently rated by Standard & Poor's Ratings Services ("S&P") or Fitch, Inc. ("Fitch"), or, if unrated, determined by PIMCO to be of comparable quality (except such 30% limitation shall not apply to the Fund's investments in mortgage- and asset-backed securities). In addition, the Fund may invest, without limitation, in securities of foreign issuers and may invest up to 15% of its total assets in securities and instruments that are economically tied to emerging market countries (this limitation does not apply to investment grade sovereign debt denominated in the local currency with less than 1 year remaining to maturity, which means the Fund may invest in such instruments without limitation subject to any applicable legal or regulatory limitation). The Fund will normally limit its foreign currency exposure (from non-U.S. dollar-denominated securities or currencies) to 10% of its total assets.

The Fund may invest, without limitation, in derivative instruments, such as options, futures contracts or swap agreements, or in mortgage- or asset-backed securities, subject to applicable law and any other restrictions described in the Fund's prospectus or Statement of Additional Information. The Fund may purchase or sell securities on a when-issued, delayed delivery or forward commitment basis and may engage in short sales. The Fund may, without limitation, seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as buy backs or dollar rolls). The Fund may also invest up to 10% of its total assets in preferred stock.

Investors should be aware that, during the Fund's transition from the principal investment strategies in effect prior to January 23, 2017 to the currently-effective principal investment strategies described above, certain of the Fund's holdings may represent a greater or lesser proportion of the Fund's overall net assets than is intended to be the case, under normal conditions, once the new principal investment strategies are fully implemented. As a result, during this transition period, the Fund may experience performance that is not reflective of the performance expected based on full implementation of the principal investment strategies described above. There is the risk that, during such transition period, the Fund could experience losses, including losses greater than, or gains less than, the losses or gains that would otherwise be incurred were the strategies fully implemented.

In addition, effective January 23, 2017, "Contingent Convertible Securities Risk" and "Basis Risk" are deleted from the "Principal Risks" section of the Fund's Fund Summary in the Prospectus.

In addition, effective January 23, 2017, the Fund's primary broad-based securities market index is the Bloomberg Barclays U.S. Aggregate 1-3 Years Index, and the Fund will no longer compare its performance to a secondary benchmark index. In addition, effective January 23, 2017, the Fund will compare its performance to the Lipper Short Investment Grade Debt Funds Average, and the Fund will no longer compare its performance to the Lipper Multi-Sector Income Funds Average. Accordingly, effective January 23, 2017, the first, second, third and fourth paragraphs of the "Performance Information" section of the Fund's Fund Summary in the Prospectus are deleted in their entirety and replaced with the following:

The performance information shows summary performance information for the Fund in a bar chart and an Average Annual Total Returns table. The information provides some indication of the risks of investing in the Fund by showing changes in its performance from year to year and by showing how the Fund's average annual returns compare with the returns of a broad-based securities market index and an index of similar funds. Absent any applicable fee waivers and/or expense limitations, performance would have been lower. The bar chart shows performance of the Fund's Institutional Class shares. For periods prior to the inception date of Class P shares (April 30, 2008), Administrative Class shares (December 30, 2005) and Class C shares (September 30, 2004), performance information shown in the table for these classes is based on the performance of the Fund's Institutional Class shares, adjusted to reflect the actual distribution and/or service (12b-1) fees and other expenses paid by these classes of shares. Performance for Class A and Class C shares in the Average Annual Total Returns table reflects the impact of sales charges. The Fund's past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future.

Effective January 23, 2017, the Fund's primary broad-based securities market index is the Bloomberg Barclays U.S. Aggregate 1-3 Years Index. The Bloomberg Barclays U.S. Aggregate 1-3 Years Index is the 1-3 Year component of the Bloomberg Barclays U.S. Aggregate Index. The Bloomberg Barclays U.S. Aggregate Index represents securities that are SEC-registered, taxable and dollar denominated. The index covers the U.S. investment grade fixed rate bond market, with index components for government and corporate securities, mortgage pass-through securities and asset-backed securities. These major sectors are subdivided into more specific indices that are calculated and reported on a regular basis. Prior to January 23, 2017, the Fund's primary benchmark index was the 3 Month USD LIBOR (London Interbank Offered Rate) Index. The 3 Month USD LIBOR Index is an average interest rate, determined by the ICE Benchmark Administration, that banks charge one another for the use of short-term money (3 months) in England's Eurodollar market.

The Lipper Short Investment Grade Debt Funds Average is a total return performance average of funds tracked by Lipper, Inc. that invest at least 65% of their assets in investment-grade debt issues (rated in the top four grades) with dollar-weighted average maturities of less than three years.

In addition, effective January 23, 2017, corresponding changes are made to the Average Annual Total Returns Table in the "Performance Information" section of the Fund's Fund Summary in the Prospectus, and the following is added above the row relating to the 3 Month USD LIBOR Index:

	1 Year	5 Years	10 Years
Bloomberg Barclays U.S. Aggregate 1-3 Years Index (reflects no deductions for fees, expenses or taxes)	0.67%	1.04%	2.83%

In addition, effective January 23, 2017, the following is added below the row relating to the 3 Month USD LIBOR Index:

	1 Year	5 Years	10 Years
Lipper Short Investment Grade Debt Funds Average (reflects no deductions for taxes)	0.24%	1.37%	2.53%

PIMCO Total Return ESG Fund

In addition, effective January 6, 2017, the first paragraph of the "Principal Investment Strategies" section of the Fund's Fund Summary in the Prospectus is deleted in its entirety and replaced with the following:

The Fund seeks to achieve its investment objective by investing under normal circumstances at least 65% of its total assets in a diversified portfolio of Fixed Income Instruments of varying maturities, which may be represented by forwards or derivatives such as options, futures contracts, or swap agreements. "Fixed Income Instruments" include bonds, debt securities and other similar instruments issued by various U.S. and non-U.S. public- or private-sector entities. The average portfolio duration of this Fund normally varies within two years (plus or minus) of the portfolio duration of the securities comprising the Barclays U.S. Aggregate Index, as calculated by PIMCO, which as of May 31, 2016 was 5.35 years. Duration is a measure used to determine the sensitivity of a security's price to changes in interest rates. The longer a security's duration, the more sensitive it will be to changes in interest rates. The Fund will not invest in the securities of any issuer determined by PIMCO to be engaged principally in the manufacture of alcoholic beverages, tobacco products or military equipment, the operation of gambling casinos, the production of coal, or in the production or trade of pornographic materials. In addition, the Fund will not invest in the securities of any issuer determined by PIMCO to be engaged principally in the provision of healthcare services or the manufacture of pharmaceuticals, unless the issuer derives 100% of its gross revenues from products or services designed to protect and improve the quality of human life, as determined on the basis of information available to PIMCO. To the extent possible on the basis of information available to PIMCO, an issuer will be deemed to be principally engaged in an activity if it derives more than 10% of its gross revenues from such activities. In addition, the Fund will not invest directly in securities of issuers that are engaged in certain business activities in or with the Republic of the Sudan.

In analyzing whether an issuer meets any of the criteria described above, PIMCO may rely upon, among other things, information provided by an independent third party.

The Fund may avoid investment in the securities of issuers whose business practices with respect to the environment, social responsibility, and governance ("ESG practices") are not to PIMCO's satisfaction. In determining the efficacy of an issuer's ESG practices, PIMCO will use its own proprietary assessments of material ESG issues and may also reference standards as set forth by recognized global organizations such as entities sponsored by the United Nations. Additionally, PIMCO may engage proactively with issuers to encourage them to improve their ESG practices. PIMCO's activities in this respect may include, but are not limited to, direct dialogue with company management, such as through in-person meetings, phone calls, electronic communications, and letters. Through these engagement activities, PIMCO seeks to identify opportunities for a company to improve its ESG practices, and will endeavor to work collaboratively with company management to establish concrete objectives and to develop a plan for meeting these objectives. The Fund may invest in securities of issuers whose ESG practices are currently suboptimal, with the expectation that these practices may improve over time either as a result of PIMCO's engagement efforts or through the company's own initiatives. It may also exclude those issuers that are not receptive to PIMCO's engagement efforts, as determined in PIMCO's sole discretion.

In addition, effective January 6, 2017, the following is added to the "Principal Risks" section of the Fund's Fund Summary in the Prospectus:

Responsible Investing Risk: the risk that, because the Fund's responsible investment strategy may select or exclude securities of certain issuers for reasons other than performance, the Fund may underperform funds that do not utilize a responsible investment strategy. Responsible investing is qualitative and subjective by nature, and there is no guarantee that the criteria utilized by PIMCO or any judgment exercised by PIMCO will reflect the beliefs or values of any particular investor

In addition, the Fund may invest, without limitation, in securities of foreign issuers and may invest up to 15% of its total assets in securities and instruments that are economically tied to emerging market countries (this limitation does not apply to investment grade sovereign debt denominated in the local currency with less than 1 year remaining to maturity, which means the Fund may invest in such instruments without limitation subject to any applicable legal or regulatory limitation). The Fund will normally limit its foreign currency exposure (from non-U.S. dollar-denominated securities or currencies) to 10% of its total assets.

The Fund may invest, without limitation, in derivative instruments, such as options, futures contracts or swap agreements, or in mortgage- or asset-backed securities, subject to applicable law and any other restrictions described in the Fund's prospectus or Statement of Additional Information.

There is the risk that, during such transition period, the Fund could experience losses, including losses greater than, or gains less than, the losses or gains that would otherwise be incurred were the strategies fully implemented.
