Fund Summary Information

Federated Hermes Government Money Fund II (the “Fund”)

RISK/RETURN SUMMARY: INVESTMENT OBJECTIVE

The Fund is a money market fund that seeks to maintain a stable net asset value (NAV) of $1.00 per Share. The Fund’s investment objective is to provide current income consistent with stability of principal and liquidity.

RISK/RETURN SUMMARY: FEES AND EXPENSES

Note: The Table below and the Example that follows it relate exclusively to the Service Shares (S) of the Fund. They do not reflect any additional fees or expenses that may be imposed by separate accounts of insurance companies or in connection with any variable annuity or variable life insurance contract. If these had been included, your costs would be higher.

This table describes the fees and expenses that you may pay if you buy, hold and sell S class of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.

Shareholder Fees (fees paid directly from your investment)

	S
Maximum Sales Charge (Load) Imposed on Purchases (as a percentage of offering price)	N/A
Maximum Deferred Sales Charge (Load) (as a percentage of original purchase price or redemption proceeds, as applicable)	N/A
Maximum Sales Charge (Load) Imposed on Reinvested Dividends (and other Distributions) (as a percentage of offering price)	N/A
Redemption Fee (as a percentage of amount redeemed, if applicable)	N/A
Exchange Fee	N/A

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

	S
Management Fee	0.15%
Distribution (12b-1) Fee	None
Other Expenses	0.57%1
Total Annual Fund Operating Expenses	0.72%
Fee Waivers and/or Expense Reimbursements2	(0.09)%
Total Annual Fund Operating Expenses After Fee Waivers and/or Expense Reimbursements	0.63%

The Fund may incur and pay administrative service fees of up to 0.25% of average net assets to insurance companies for providing recordkeeping,

shareholder and administrative services.

The Adviser and certain of its affiliates, on their own initiative, have agreed to waive certain amounts of their respective fees and/or reimburse expenses. Total

annual fund operating expenses (excluding acquired fund fees and expenses, interest expense, extraordinary expenses, and proxy-related expenses, if any)

paid by the Fund’s S class (after the voluntary waivers and/or reimbursements) will not exceed 0.63% (the “Fee Limit”) up to but not including the later of (the

“Termination Date”): (a) May 1, 2027; or (b) the date of the Fund’s next effective Prospectus. While the Adviser and its affiliates currently do not anticipate terminating or increasing these arrangements prior to the Termination Date, these arrangements may only be terminated or the Fee Limit increased prior to the Termination Date with the approval of the Trustees.

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 for the time periods indicated and then redeem or hold all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that operating expenses remain the same. The Example does not reflect sales charges (loads) on reinvested dividends. If these sales charges (loads) were included, your costs would be higher. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year	$74
3 Years	$230
5 Years	$401
10 Years	$894

RISK/RETURN SUMMARY: INVESTMENTS, RISKS and PERFORMANCE

What are the Fund’s Main Investment Strategies?

The Fund invests in a portfolio of U.S. Treasury and government securities maturing in 397 days or less, as well as repurchase agreements collateralized fully by U.S. Treasury and government securities. The Fund may also hold cash.

Certain of the government securities in which the Fund invests are not backed by the full faith and credit of the U.S. government, such as those issued by the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal National Mortgage Association (“Fannie Mae”) and the Federal Home Loan Bank System. These entities are, however, supported through federal subsidies, loans or other benefits. The Fund may also invest in government securities that are supported by the full faith and credit of the U.S. government, such as those issued by the Government National Mortgage Association (“Ginnie Mae”). Finally, to a lesser extent, the Fund may invest in certain government securities that are issued by entities whose activities are sponsored by the federal government, but that have no explicit financial support.

In pursuing its investment objective and implementing its investment strategies, the Fund will comply with Rule 2a-7 under the Investment Company Act of 1940 (“Rule 2a-7”).

The Fund will operate as a “government money market fund,” as such term is defined in or interpreted under Rule 2a-7 under the Investment Company Act of 1940, as amended (the “1940 Act”). “Government money market funds” are required to invest at least 99.5% of their total assets in: (i) cash; (ii) securities issued or guaranteed by the United States or certain U.S. government agencies or instrumentalities; and/or (iii) repurchase agreements that are collateralized fully. Government money market funds are not required to adopt a liquidity fee framework.

Under normal conditions, the Fund will invest its assets so that at least 80% of its net assets (plus any borrowings for investment purposes) are invested in government securities and/or repurchase agreements that are collateralized fully by government securities. The Fund will notify shareholders at least 60 days in advance of any change in this investment policy.

What are the Main Risks of Investing in the Fund?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund. The primary factors that may negatively impact the Fund’s ability to maintain a stable NAV, delay the payment of redemptions by the Fund, or reduce the Fund’s daily dividends include:

■ Interest Rate Risk. Prices of fixed-income securities generally fall when interest rates rise. Recent and potential future changes in monetary policy made by central banks and/or their governments are likely to affect the level of interest rates. Very low or negative interest rates magnify interest rate risk. During periods when interest rates are low or there are negative interest rates, the Fund’s yield (and total return) also is likely to be lower or the Fund may be unable to maintain a positive return, or yield, or a stable NAV.

■ Issuer Credit Risk. It is possible that interest or principal on securities will not be paid when due. Money market funds try to minimize this risk by purchasing higher-quality securities.

■ Counterparty Risk. A party to a transaction involving the Fund may fail to meet its obligations. This could cause the Fund to lose money or to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategies.

■ Call Risk. The Fund’s performance may be adversely affected by the possibility that an issuer of a security held by the Fund may redeem the security prior to maturity at a price below its current market value.

■ Risk Associated with Investing Share Purchase Proceeds. On days during which there are net purchases of Fund Shares, the Fund must invest the proceeds at prevailing market yields or hold cash. If the Fund holds cash, or if the yield of the securities purchased is less than that of the securities already in the portfolio, the Fund’s yield will likely decrease. Conversely, net purchases on days on which short-term yields rise will likely cause the Fund’s yield to increase. In the event of significant changes in short-term yields or significant net purchases, the Fund retains the discretion to close to new investments. However, the Fund is not required to close, and no assurance can be given that this will be done in any given circumstance.

■ Risk Associated with Use of Amortized Cost. In the unlikely event that the Fund’s Board of Trustees (“Board”) were to determine, pursuant to Rule 2a-7, that the extent of the deviation between the Fund’s amortized cost per Share and its market-based NAV per Share may result in material dilution or other unfair results to shareholders, the Board will cause the Fund to take such action as it deems appropriate to eliminate or reduce to the extent practicable such dilution or unfair results.

■ Additional Factors Affecting Yield. There is no guarantee that the Fund will provide a certain level of income or that any such income will exceed the rate of inflation. Further, the Fund’s yield will vary. Periods of very low or negative interest rates impact, in a negative way, the Fund’s ability to maintain a positive return, or yield, or pay dividends to Fund shareholders.

■ Risk Related to the Economy. The value of the Fund’s portfolio may decline in tandem with a drop in the overall value of the markets in which the Fund invests and/or other markets. Global economic, political and financial conditions, including geopolitical and other events (e.g., wars, tensions, sanctions and terrorism), legislative changes or shifts in fiscal or monetary policy or reform, industry or economic trends and developments, grid congestion or capacity constraints, natural disasters or public health risks, such as epidemics or pandemics, may, from time to time, and for varying periods of time, have a significant effect on the economies of many nations, including the U.S., and financial markets generally and cause the Fund to experience volatility, illiquidity, loss of value, shareholder redemptions and/or other potentially adverse effects.

■ Technology Risk. The Adviser uses various technologies in managing the Fund, consistent with its investment objective(s) and strategy described in this Prospectus. For example, proprietary and third-party data and systems are utilized to support decision-making for the Fund. Data imprecision, software or other technology malfunctions, programming inaccuracies and similar circumstances may impair the performance of these systems, which may negatively affect Fund performance.

You could lose money by investing in the Fund. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. An investment in the Fund is not a bank account and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund’s sponsor is not required to reimburse the Fund for losses, and you should not expect that the sponsor will provide financial support to the Fund at any time, including during periods of market stress.

FUND MANAGEMENT

The Fund’s Investment Adviser is Federated Investment Management Company.

PURCHASE AND SALE OF FUND SHARES

Shares are used solely as an investment vehicle for separate accounts of participating insurance companies offering variable annuity contracts and variable life insurance policies. The general public has access to the Fund only by purchasing a variable annuity contract or variable life insurance policy (thus becoming a contract owner). Shares are not sold directly to the general public.

Shares of the Fund can be purchased or redeemed by participating insurance companies on any day the New York Stock Exchange (NYSE) is open.

Tax Information

The Fund expects, based on its investment objectives and strategies, that its distributions, if any, will consist of ordinary income, capital gains or some combination of both. Because shares of the Fund must be purchased through variable annuity contracts or variable life insurance contracts, such distribution will be exempt from current taxation if left to accumulate within the variable contract. You should ask your own tax advisor for more information on your own tax situation, including possible state or local taxes.

Payments to Insurance companies or qualifying dealers

Fund Shares are generally available only through participating insurance companies offering variable annuity contracts and variable life insurance policies. Life insurance policies and variable annuities are generally purchased through a broker-dealer or other financial intermediary. The Fund and/or its related companies may make payments to the participating insurance companies for services; some of the payments may go to broker-dealers and other intermediaries. These payments may create a conflict of interest for an intermediary, or be a factor in the participating insurance companies’ decision to include the Fund as an underlying investment option in a variable contract. Ask your salesperson or visit your financial intermediary’s website for more information.
