Letter from the President

Dear Shareholder:

We hope you find the semiannual report for PGIM Government Income Fund informative and useful. The report covers performance for the six-month period ended August 31, 2019.

Regarding your investments with PGIM, we believe it is important to maintain a diversified portfolio of funds consistent with your tolerance for risk, time horizon, and financial goals.

Your financial advisor can help you create a diversified investment plan that may include funds covering all the basic asset classes and that reflects your personal investor profile and risk tolerance. However, diversification and asset allocation strategies do not assure a profit or protect against loss in declining markets.

At PGIM Investments, we consider it a great privilege and responsibility to help investors participate in opportunities across global markets while meeting their toughest investment challenges. PGIM is a top-10 global investment manager with more than $1 trillion in assets under management. This investment expertise allows us to deliver actively managed funds and strategies to meet the needs of investors around the globe.

Thank you for choosing our family of funds.

Sincerely,

Stuart S. Parker, President

PGIM Government Income Fund

The investment return and principal value of an investment 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 the past performance data quoted.

*Not annualized

Since Inception returns are provided for any share class with less than 10 fiscal years of returns. Since Inception returns for the Indexes and the Lipper Average are measured from the closest month-end to the class’ inception date.

The returns in the tables do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or following the redemption of Fund shares. The average annual total returns take into account applicable sales charges, which are described for each share class in the table below.

*Class B shares are closed to all purchase activity and no additional Class B shares may be purchased or acquired except by exchange from Class B shares of another Fund or through dividend or capital gains reinvestment.

Benchmark Definitions

Bloomberg Barclays US Government Bond Index—The Bloomberg Barclays US Government Bond Index is an unmanaged index of securities issued or backed by the US government, its agencies, and instrumentalities

Your Fund’s Performance (continued)

with between one and 30 years remaining to maturity. It gives a broad look at how US government bonds have performed. The average annual total return for the Index measured from the month-end closest to the inception date of the Fund’s Class R6 shares is 2.27%.

Bloomberg Barclays US Aggregate ex-Credit Index—The Bloomberg Barclays US Aggregate ex-Credit Index is an unmanaged index that represents securities that are SEC registered, taxable, and dollar denominated. The Index covers the US 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 indexes that are calculated and reported on a regular basis. The average annual total return for the Index measured from the month-end closest to the inception date of the Fund’s Class R6 shares is 2.35%.

Lipper General US Government Funds Average—The Lipper General US Government Funds Average (Lipper Average) is based on the average return of all funds in the Lipper General US Government Funds universe for the periods noted. Funds in the Lipper Average invest primarily in US government and agency issues. The average annual total return for the Lipper Average measured from the month-end closest to the inception date of the Fund’s Class R6 shares is 1.81%.

Investors cannot invest directly in an index or average. The returns for the Indexes would be lower if they included the effects of sales charges, operating expenses of a mutual fund, or taxes. Returns for the Lipper Average reflect the deduction of operating expenses of a mutual fund, but not sales charges or taxes.

Credit ratings reflect the highest rating assigned by a nationally recognized statistical rating organization (NRSRO) such as Moody’s Investors Service, Inc. (Moody’s), S&P Global Ratings (S&P), or Fitch, Inc. (Fitch). Credit ratings reflect the common nomenclature used by both S&P and Fitch. Where applicable, ratings are converted to the comparable S&P/Fitch rating tier nomenclature used by both S&P and Fitch. These ratings agencies are independent and are widely used. The Not Rated category consists of securities that have not been rated by a NRSRO and may include derivative instruments that could have a negative value. Credit ratings are subject to change.

*SEC 30-Day Subsidized Yield (%)—A standardized yield calculation created by the Securities and Exchange Commission, it reflects the income earned during a 30-day period, after the deduction of the Fund’s net expenses (net of any expense waivers or reimbursements). The investor experience is represented by the SEC 30-Day Subsidized Yield.

**SEC 30-Day Unsubsidized Yield (%)—A standardized yield calculation created by the Securities and Exchange Commission, it reflects the income earned during a 30-day period, after the deduction of the Fund’s gross expenses. The investor experience is represented by the SEC 30-Day Subsidized Yield.

Fees and Expenses

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments and redemptions, as applicable, and (2) ongoing costs, including management fees, distribution and/or service (12b-1) fees, and other Fund expenses, as applicable. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 held through the six-month period ended August 31, 2019. The example is for illustrative purposes only; you should consult the Prospectus for information on initial and subsequent minimum investment requirements.

Actual Expenses

The first line for each share class in the table on the following page provides information about actual account values and actual expenses. You may use the information on this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value ÷ $1,000 = 8.6), then multiply the result by the number on the first line under the heading “Expenses Paid During the Six-Month Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line for each share class in the table on the following page provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

The Fund’s transfer agent may charge additional fees to holders of certain accounts that are not included in the expenses shown in the table on the following page. These fees apply to individual retirement accounts (IRAs) and Section 403(b) accounts. As of the close of the six-month period covered by the table, IRA fees included an annual maintenance fee of $15 per account (subject to a maximum annual maintenance fee of $25 for all accounts held by the same shareholder). Section 403(b) accounts are charged an annual $25 fiduciary maintenance fee. Some of the fees may vary in amount, or may be waived, based on your total account balance or the number of PGIM funds, including the Fund, that you own. You should consider the additional fees that were charged to your Fund account

over the six-month period when you estimate the total ongoing expenses paid over the period and the impact of these fees on your ending account value, as these additional expenses are not reflected in the information provided in the expense table. Additional fees have the effect of reducing investment returns.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs such as sales charges (loads). Therefore, the second line for each share class in the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

*Fund expenses (net of fee waivers or subsidies, if any) for each share class are equal to the annualized expense ratio for each share class (provided in the table), multiplied by the average account value over the period, multiplied by the 184 days in the six-month period ended August 31, 2019, and divided by the 366 days in the Fund’s fiscal year ending February 29, 2020 (to reflect the six-month period). Expenses presented in the table include the expenses of any underlying portfolios in which the Fund may invest.
