Registration Statement No. 333-219206

		The Goldman Sachs Group, Inc.   $500,000   Floating Rate Notes due 2021

We will pay interest quarterly on the last calendar day of each February, May, August and November of each year, commencing on November 30, 2018 to, and including, the stated maturity date (August 31, 2021) at a floating rate equal to the then-applicable 30-year CMS rate plus the spread of 0.05% per annum, subject to the minimum interest rate of 0% per annum. Your quarterly interest payments will be determined in accordance with the 30/360 (ISDA) day count convention and, therefore, on any quarterly interest payment date, interest will be paid for greater than or less than 90 days. See page S-12.

The notes will mature on the stated maturity date. On the stated maturity date, you will receive $1,000, plus any accrued and unpaid interest, for each $1,000 of the face amount of your notes. The 30-year CMS rate is based on a hypothetical interest rate swap referencing 3-month USD LIBOR. LIBOR is being modified, see page S-6.

Your investment in the notes involves certain risks, including our credit risk. See page S-6.

You should read the disclosure herein to better understand the terms and risks of your investment.

In addition to offers and sales at the initial price to public, the underwriters may offer the notes from time to time for sale in one or more transactions at market prices prevailing at the time of sale, at prices related to market prices or at negotiated prices.

Neither the Securities and Exchange Commission nor any other regulatory body has approved or disapproved of these securities or passed upon the accuracy or adequacy of this prospectus. Any representation to the contrary is a criminal offense. The notes are not bank deposits and are not insured by the Federal Deposit Insurance Corporation or any other governmental agency, nor are they obligations of, or guaranteed by, a bank.

Prospectus Supplement No. 177 dated August 29, 2018.

The issue price, underwriting discount and net proceeds listed on the cover page hereof relate to the notes we sell initially. We may decide to sell additional notes after the date of this prospectus supplement, at issue prices and with underwriting discounts and net proceeds that differ from the amounts set forth above. The return (whether positive or negative) on your investment in notes will depend in part on the issue price you pay for such notes.

Goldman Sachs may use this prospectus in the initial sale of the offered notes. In addition, Goldman Sachs & Co. LLC, or any other affiliate of Goldman Sachs may use this prospectus in a market-making transaction in a note after its initial sale. Unless Goldman Sachs or its agent informs the purchaser otherwise in the confirmation of sale, this prospectus is being used in a market-making transaction.

Supplemental discussion of U.S. federal income tax consequences: The notes will be treated as variable rate debt instruments for U.S. federal income tax purposes. Under this characterization, it is the opinion of Sidley Austin LLP that you should include qualified stated interest (i.e., the interest payments) in ordinary income at the time you receive or accrue such payments, depending on your regular method of accounting for tax purposes. In addition, any gain or loss you recognize upon the sale, exchange or maturity of your notes should be capital gain or loss. Please see “Supplemental Discussion of Federal Income Tax Consequences” below for a more detailed discussion.

Interest rate: a rate per annum equal to the base rate, determined on the relevant interest determination date, plus the spread, subject to the minimum interest rate; for the initial interest period the base rate shall be the initial base rate

Base rate: 30-year CMS rate (as described under “Historical 30-Year CMS Rates”, “Additional Information About the Notes – 30-Year CMS Rate” and “Discontinuance of the CMS base rate” below).

Initial base rate: 30-year CMS rate in effect on August 29, 2018

Discontinuance of the CMS base rate: if the calculation agent determines on an interest determination date that the CMS base rate has been discontinued, then the calculation agent will use a substitute or successor base rate that it has determined in its sole discretion is most comparable to the CMS base rate, provided that if the calculation agent determines there is an industry-accepted successor base rate, then the calculation agent shall use such successor base rate. If the calculation agent has determined a substitute or successor base rate in accordance with the foregoing, the calculation agent in its sole discretion may determine the business day convention, the applicable business days and the interest determination dates to be used, and any other relevant methodology for calculating such substitute or successor base rate comparable to the CMS base rate, including any adjustment factor needed to make such substitute or

S-3

successor rate comparable to the CMS base rate, in a manner that is consistent with industry-accepted practices for such substitute or successor base rate.

HYPOTHETICAL EXAMPLES

The following table is provided for purposes of illustration only. It should not be taken as an indication or prediction of future investment results and is intended merely to illustrate the method we will use to calculate the amount of interest accrued during each interest period.

The table below is based on 30-year CMS rates that are entirely hypothetical; no one can predict what the 30-year CMS rate will be on any day during the interest periods, and no one can predict the interest that will accrue on your notes in any interest period.

For these reasons, the actual 30-year CMS rates during the interest periods, as well as the interest payable on each interest payment date, may bear little relation to the hypothetical table shown below or to the historical 30-year CMS rates shown elsewhere in this prospectus supplement. For information about the 30-year CMS rates during recent periods, see “Historical 30-year CMS Rates” on page S-11. Before investing in the offered notes, you should consult publicly available information to determine the 30-year CMS rates between the date of this prospectus supplement and the date of your purchase of the offered notes.

The following table illustrates the method we will use to calculate the interest rate at which interest will accrue on each day included in each interest period, subject to the key terms and assumptions below.

The percentage amounts in the left column of the table below represent hypothetical 30-year CMS rates on a given interest determination date. The right column of the table below represent the hypothetical interest rate that would be payable on a given interest payment date, based on the corresponding hypothetical 30-year CMS rate. The information in the table also reflects the key terms and assumptions in the box below.

Also, the hypothetical examples shown below do not take into account the effects of applicable taxes.

* Interest is floored at the minimum interest rate of 0.00% per annum for the interest payment dates.

Payments on the notes are economically equivalent to the amounts that would be paid on a combination of other instruments. For example, payments on the notes are economically equivalent to the amounts that would be paid on a combination of an interest-bearing bond bought, and an option bought, by the holder (with an implicit option premium paid over time by the holder). The discussion in this paragraph does not modify or affect the terms of the notes or the United States income tax treatment of the notes, as described elsewhere in this prospectus supplement.

ADDITIONAL RISK FACTORS SPECIFIC TO YOUR NOTES

The Notes Are Subject to the Credit Risk of the Issuer

Although the return on the notes will be based in part on the performance of the 30-year CMS rate, the payment of any amount due on the notes is subject to our credit risk. The notes are our unsecured obligations. Investors are dependent on our ability to pay all amounts due on the notes, and therefore investors are subject to our credit risk and to changes in the market’s view of our creditworthiness. See “Description of the Notes We May Offer — Information About Our Medium-Term Notes, Series N Program — How the Notes Rank Against Other Debt” on page S-5 of the accompanying prospectus supplement.

We May Sell an Additional Aggregate Face Amount of the Notes at a Different Issue Price

At our sole option, we may decide to sell an additional aggregate face amount of the notes subsequent to the date of this prospectus supplement. The issue price of the notes in the subsequent sale may differ substantially (higher or lower) from the issue price you paid as provided on the cover of this prospectus supplement.

The Amount of Interest Payable on Your Notes Will Not Be Affected by the 30-Year CMS Rate on Any Day Other Than an Interest Determination Date

For each interest period, the amount of interest payable on each interest payment date is calculated based on the 30-year CMS rate on the applicable interest determination date plus the spread. Although the actual 30-year CMS rate on an interest payment date or at other times during an interest period may be higher than the 30-year CMS rate on the applicable interest determination date, you will not benefit from the 30-year CMS rate at any time other than on the interest determination date for such interest period.

Recent Regulatory Investigations Regarding Potential Manipulation of ISDAfix May Adversely Affect Your Notes

It has been reported that the U.K. Financial Conduct Authority and the U.S. Commodity Futures Trading Commission are working together to investigate potential manipulation of ISDAfix. If such manipulation occurred, it may have resulted in the 30-year CMS rate being artificially lower (or higher) than it would otherwise have been. Any changes or reforms affecting the determination or supervision of ISDAfix (or ICE Swap Rate) in light of these investigations may result in a sudden or prolonged increase or decrease in reported ISDAfix (or ICE Swap Rate), which could have an adverse impact on the trading market for ISDAfix (or ICE Swap Rate)-benchmarked securities such as your notes, the value of your notes and any payments on your notes.

The 30-Year CMS Rate is Based on a Hypothetical Interest Rate Swap Referencing 3-Month USD LIBOR; U.K. Regulators Will No Longer Persuade or Compel Banks to Submit Rates for Calculation of LIBOR After 2021; Interest Rate Benchmark May Be Discontinued

The 30-year CMS rate represents the fixed rate of interest payable on a hypothetical interest rate swap with a floating leg based on 3-month USD LIBOR. On July 27, 2017, the Chief Executive of the U.K. Financial Conduct Authority (FCA), which regulates LIBOR, announced that the FCA will no longer persuade or compel banks to submit rates for the calculation of LIBOR (which includes the 3-month USD LIBOR rate) after 2021. Such announcement indicates that the continuation of LIBOR on the current basis cannot and will not be guaranteed after 2021. Notwithstanding the foregoing, it appears highly likely that LIBOR will be discontinued or modified by 2021. It is not possible to predict the effect that this announcement or any such discontinuance or modification will have on the 3-month USD LIBOR rate, the 30-year CMS rate or your notes. If the calculation agent determines on an interest determination date that the 30-year CMS rate has been discontinued, then the calculation agent will use a substitute or successor base rate that it has determined in its sole discretion is most comparable to the 30-year CMS rate, provided that if the calculation agent determines there is an industry-accepted successor base rate, then the calculation agent shall use such successor base rate. If the calculation agent has determined a substitute or successor base rate in accordance with the foregoing, the calculation agent in its sole discretion may determine the business day convention, the applicable business days and the interest determination dates to be used, and any other relevant methodology for calculating such substitute or successor base rate, including any adjustment factor needed to make such substitute or successor base rate comparable to the 30-year CMS rate, in a

S-7

manner that is consistent with industry-accepted practices for such substitute or successor base rate. See “Specific Terms of Your Notes — Key Terms — Discontinuance of the CMS base rate” on page S-4.

Even if the 30-Year CMS Rate is Not Discontinued, Such Rate May Not Be Published on an Interest Determination Date and, If Such Rate is Not Published, it May Be Calculated Based on Dealer Quotations or by the Calculation Agent in its Sole Discretion

Even if the 30-year CMS rate is not discontinued, it is possible that such rate may not be available on the applicable interest determination date because such rate is not published by the Intercontinental Exchange (ICE). Non-publication by ICE of the applicable CMS rate (ICE Swap Rate) could occur for a number of reasons, such as a lack of available market data and an inability to use available market data to estimate rates for index maturities that are not available, or for other reasons. For example, on February 6, 2018, no CMS Rate (ICE Swap Rate) was published for any index maturity. If the 30-year CMS rate cannot be determined using the Reuters ICESWAP1 page due to the non-publication of such rate on a given interest determination date, the calculation agent will determine such rate on the basis of the mid-market semi-annual swap rate quotations provided by five leading swap dealers in the New York City interbank market at approximately 11:00 a.m., New York City time, on that date. If fewer than three quotations are provided as requested (as occurred in relation to the February 6, 2018 non-publication of the 10-year CMS rate), the 30-year CMS rate will be determined by the calculation agent in its sole discretion. See “Additional Information About the Notes — 30-Year CMS Rate” on page S-12. If, after an interest determination date, you would like to know the level of the 30-year CMS rate on such interest determination date, please call GS&Co. at (212) 902-0300.

Regulation and Reform of “Benchmarks”, Including LIBOR and Other Types of Benchmarks, May Cause Such “Benchmarks” to Perform Differently Than in the Past, or to Disappear Entirely, or Have Other Consequences Which Cannot be Predicted

LIBOR and other interest rate, equity, foreign exchange rate and other types of indices which are deemed to be “benchmarks” are the subject of recent national, international and other regulatory guidance and proposals for reform. Some of these reforms are already effective while others are still to be implemented. These reforms may cause such “benchmarks” to perform differently than in the past, or to disappear entirely, or have other consequences which cannot be predicted. Any such consequence could have a material adverse effect on your notes.

Any of the international, national or other proposals for reform or the general increased regulatory scrutiny of “benchmarks” could increase the costs and risks of administering or otherwise participating in the setting of a “benchmark” and complying with any such regulations or requirements. Such factors may have the effect of discouraging market participants from continuing to administer or contribute to certain “benchmarks”, trigger changes in the rules or methodologies used in certain “benchmarks” or lead to the disappearance of certain “benchmarks”. The disappearance of a “benchmark” or changes in the manner of administration of a “benchmark” could result in discretionary valuation by the calculation agent or other consequence in relation to your notes. Any such consequence could have a material adverse effect on the value of and return on your notes.

The Historical Levels of the 30-Year CMS Rate Are Not an Indication of the Future Levels of the

30-Year CMS Rate

In the past, the level of the 30-year CMS rate has experienced significant fluctuations. You should note that historical levels, fluctuations and trends of the 30-year CMS rate are not necessarily indicative of future levels. Any historical upward or downward trend in the 30-year CMS rate is not an indication that the 30-year CMS rate is more or less likely to increase or decrease at any time during an interest period, and you should not take the historical levels of the 30-year CMS rate as an indication of its future performance.

If You Purchase Your Notes at a Premium to Face Amount, the Return on Your Investment Will Be Lower Than the Return on Notes Purchased at Face Amount and the Impact of Certain Key Terms of the Notes Will be Negatively Affected

The amount you will be paid for your notes on the stated maturity date will not be adjusted based on the issue price you pay for the notes. If you purchase notes at a price that differs from the face amount of the notes, then the return on your investment in such notes held to the stated maturity date will differ from, and may be substantially less than, the return on notes purchased at face amount. If you purchase your notes at a premium to face amount and hold them to the stated maturity date, the return on your investment in the notes will be lower than it would have been had you purchased the notes at face amount or a discount to face amount.

The Market Value of Your Notes May Be Influenced by Many Unpredictable Factors

When we refer to the market value of your notes, we mean the value that you could receive for your notes if you chose to sell them in the open market before the stated maturity date. A number of factors, many of which are beyond our control, will influence the market value of your notes, including:

S-8

These factors, and many other factors, will influence the price you will receive if you sell your notes before maturity, including the price you may receive for your notes in any market making transaction. If you sell your notes before maturity, you may receive less than the face amount of your notes.

You cannot predict the future performance of the 30-year CMS rate based on its historical performance. The actual performance of the 30-year CMS rate over the life of the offered notes may bear little or no relation to the historical levels of the 30-year CMS rate or to the hypothetical examples shown elsewhere in this prospectus supplement.

If the 30-Year CMS Rate Changes, the Market Value of Your Notes May Not Change in the Same Manner

The price of your notes may move differently than the 30-year CMS rate. Changes in the 30-year CMS rate may not result in a comparable change in the market value of your notes. We discuss some of the reasons for this disparity under “— The Amount of Interest Payable on Your Notes Will Not Be Affected by the 30-year CMS rate on Any Day Other Than an Interest Determination Date” and “— The Market Value of Your Notes May Be Influenced by Many Unpredictable Factors” above.

Anticipated Hedging Activities by Goldman Sachs or Our Distributors May Negatively Impact Investors in the Notes and Cause Our Interests and Those of Our Clients and Counterparties to be Contrary to Those of Investors in the Notes

Goldman Sachs expects to hedge our obligations under the notes by purchasing futures and/or other instruments linked to 30-year CMS rate. Goldman Sachs also expects to adjust the hedge by, among other things, purchasing or selling any of the foregoing, and perhaps other instruments linked to 30-year CMS rate, at any time and from time to time, and to unwind the hedge by selling any of the foregoing on or before the final interest determination date for your notes. Alternatively, Goldman Sachs may hedge all or part of our obligations under the notes with unaffiliated distributors of the notes which we expect will undertake similar market activity. Goldman Sachs may also enter into, adjust and unwind hedging transactions relating to other 30-year CMS rate-linked notes whose returns are linked to 30-year CMS rate.

In addition to entering into such transactions itself, or distributors entering into such transactions, Goldman Sachs may structure such transactions for its clients or counterparties, or otherwise advise or assist clients or counterparties in entering into such transactions. These activities may be undertaken to achieve a variety of objectives, including: permitting other purchasers of the notes or other securities to hedge their investment in whole or in part; facilitating transactions for other clients or counterparties that may have business objectives or investment strategies that are inconsistent with or contrary to those of investors in the notes; hedging the exposure of Goldman Sachs to the notes including any interest in the notes that it reacquires or retains as part of the offering process, through its market-making activities or otherwise; enabling Goldman Sachs to comply with its internal risk limits or otherwise manage firmwide, business unit or product risk; and/or enabling Goldman Sachs to take directional views as to relevant markets on behalf of itself or its clients or counterparties that are inconsistent with or contrary to the views and objectives of the investors in the notes.

Any of these hedging or other activities may adversely affect the levels of 30-year CMS rate — and therefore the market value of your notes and the amount we will pay on your notes at maturity. In addition, you should expect that these transactions will cause Goldman Sachs or its clients, counterparties or distributors to have economic interests and incentives that do not align with, and that may be directly contrary to, those of an investor in the notes. Neither Goldman Sachs nor any distributor will have any obligation to take, refrain from taking or cease taking any action with respect to these transactions based on the potential effect on an investor in the notes, and may receive substantial returns on hedging or other activities while the value of your notes declines. In addition, if the distributor from which you purchase notes is to conduct hedging activities in connection with the notes, that distributor may otherwise profit in connection with such hedging activities and such profit, if any, will be in addition to the compensation that the distributor receives for the sale of the notes to you. You should be aware that the potential to earn fees in connection with hedging activities may

S-9

create a further incentive for the distributor to sell the notes to you in addition to the compensation they would receive for the sale of the notes.

As Calculation Agent, Goldman Sachs & Co. LLC Will Have the Authority to Make Determinations that Could Affect the Value of Your Notes and the Amount You May Receive On Any Interest Payment Date

As calculation agent for your notes, Goldman Sachs & Co. LLC will have discretion in making certain determinations that affect your notes, including determining the 30-year CMS rate on any interest determination date, which we will use to determine the amount we will pay on any applicable interest payment date. Further, if Goldman Sachs & Co. LLC determines on an interest determination date that the 30-year CMS rate has been discontinued, then Goldman Sachs & Co. LLC will use a substitute or successor base rate that it has determined in its sole discretion is most comparable to the 30-year CMS rate, provided that if Goldman Sachs & Co. LLC determines there is an industry-accepted successor base rate, then Goldman Sachs & Co. LLC shall use such successor base rate. If Goldman Sachs & Co. LLC has determined a substitute or successor base rate in accordance with the foregoing, Goldman Sachs & Co. LLC in its sole discretion may determine the business day convention, the applicable business days and the interest determination dates to be used, and any other relevant methodology for calculating such substitute or successor base rate, including any adjustment factor needed to make such substitute or successor base rate comparable to the 30-year CMS rate, in a manner that is consistent with industry-accepted practices for such substitute or successor base rate. See “Specific Terms of Your Notes — Key Terms — Discontinuance of the CMS base rate” on page S-4. The exercise of this discretion by Goldman Sachs & Co. LLC could adversely affect the value of your notes and may present Goldman Sachs & Co. LLC with a conflict of interest. We may change the calculation agent at any time without notice and Goldman Sachs & Co. LLC may resign as calculation agent at any time upon 60 days’ written notice to Goldman Sachs.

Your Notes May Not Have an Active Trading Market

Your notes will not be listed or displayed on any securities exchange or included in any interdealer market quotation system, and there may be little or no secondary market for your notes. Even if a secondary market for your notes develops, it may not provide significant liquidity and we expect that transaction costs in any secondary market would be high. As a result, the difference between bid and asked prices for your notes in any secondary market could be substantial.

Certain Considerations for Insurance Companies and Employee Benefit Plans

Any insurance company or fiduciary of a pension plan or other employee benefit plan that is subject to the prohibited transaction rules of the Employee Retirement Income Security Act of 1974, as amended, which we call “ERISA”, or the Internal Revenue Code of 1986, as amended, including an IRA or a Keogh plan (or a governmental plan to which similar prohibitions apply), and that is considering purchasing the offered notes with the assets of the insurance company or the assets of such a plan, should consult with its counsel regarding whether the purchase or holding of the offered notes could become a “prohibited transaction” under ERISA, the Internal Revenue Code or any substantially similar prohibition in light of the representations a purchaser or holder in any of the above categories is deemed to make by purchasing and holding the offered notes. This is discussed in more detail under “Employee Retirement Income Security Act” below.

Foreign Account Tax Compliance Act (FATCA) Withholding May Apply to Payments on Your Notes, Including as a Result of the Failure of the Bank or Broker Through Which You Hold the Notes to Provide Information to Tax Authorities

Please see the discussion under “United States Taxation — Taxation of Debt Securities — Foreign Account Tax Compliance Act (FATCA) Withholding” in the accompanying prospectus for a description of the applicability of FATCA to payments made on your notes.

S-10

USE OF PROCEEDS

We will use the net proceeds we receive from the sale of the offered notes for the purposes we describe in the accompanying prospectus under “Use of Proceeds”.

HEDGING

In anticipation of the sale of the offered notes, we and/or our affiliates have entered into or expect to enter into hedging transactions involving purchases of instruments linked to the 30-year CMS rate. In addition, from time to time, we and/or our affiliates expect to enter into additional hedging transactions and to unwind those we have entered into, in connection with the offered notes and perhaps in connection with other notes we issue, some of which may have returns linked to the 30-year CMS rate. Consequently, with regard to your notes, from time to time, we and/or our affiliates:

We and/or our affiliates may also acquire a long or short position in securities similar to your notes from time to time and may, in our or their sole discretion, hold or resell those securities.

In the future, we and/or our affiliates expect to close out hedge positions relating to the offered notes and perhaps relating to other notes with returns linked to the 30-year CMS rate. These steps may also involve sales and/or purchases of some or all of the listed or over-the-counter options, futures or other instruments linked to the 30-year CMS rate.

S-11

ADDITIONAL INFORMATION ABOUT THE NOTES

30-Year CMS Rate

In this prospectus supplement, when we refer to the 30-year CMS rate, we mean the rate as it appears on Reuters screen ICESWAP1 page under the heading 30-year index maturity for rates at approximately 11:00 a.m. New York time, on each interest determination date.

If the calculation agent determines on an interest determination date that the CMS base rate has been discontinued, then the calculation agent will use a substitute or successor base rate that it has determined in its sole discretion is most comparable to the CMS base rate, provided that if the calculation agent determines there is an industry-accepted successor base rate, then the calculation agent shall use such successor base rate. If the calculation agent has determined a substitute or successor base rate in accordance with the foregoing, the calculation agent in its sole discretion may determine the business day convention, the applicable business days and the interest determination dates to be used, and any other relevant methodology for calculating such substitute or successor base rate, including any adjustment factor needed to make such substitute or successor base rate comparable to the CMS base rate, in a manner that is consistent with industry-accepted practices for such substitute or successor base rate.

Unless the calculation agent uses a substitute or successor base rate as so provided, if the 30-year CMS rate cannot be determined in the manner described above on the relevant interest determination date, the following procedures will apply to your notes.

“Reuters screen” means the display on the Thomson Reuters Eikon service, or any successor or replacement service, on the page specified in this prospectus supplement, or any successor or replacement page on that service.

Day Count Convention

As further described under “Description of Debt Securities We May Offer – Calculations of Interest on Debt Securities – Interest Rates and Interest” in the accompanying prospectus, for each interest period the amount of accrued interest will be calculated by multiplying the principal amount of the note by an accrued interest factor for the interest period. The accrued interest factor will be determined by multiplying the per annum interest rate by a factor resulting from the 30/360 (ISDA) day count convention. The factor is the number of days in the interest period in respect of which payment is being made divided by 360, calculated on a formula basis as follows, as described in Section 4.16(f) of the 2006 ISDA Definitions published by the International Swaps and Derivatives Association, without regard to any subsequent amendments or supplements:

where:

“Y₁” is the year, expressed as a number, in which the first day of the interest period falls;

S-12

“Y₂” is the year, expressed as a number, in which the day immediately following the last day included in the interest period falls;

“M₁” is the calendar month, expressed as a number, in which the first day of the interest period falls;

“M₂” is the calendar month, expressed as a number, in which the day immediately following the last day included in the interest period falls;

“D₁” is the first calendar day, expressed as a number, of the interest period, unless such number would be 31, in which case D1 will be 30; and

“D₂” is the calendar day, expressed as a number, immediately following the last day included in the interest period, unless such number would be 31 and D1 is greater than 29, in which case D2 will be 30.

Due to the 30/360 (ISDA) day count convention, the factor applicable to each interest payment date will vary, as illustrated in the table below.

S-13

HISTORICAL 30-YEAR CMS RATES

The level of the 30-year CMS rate has fluctuated in the past and may, in the future, experience significant fluctuations. Any historical upward or downward trend in the level of the 30-year CMS rate during any period shown below is not an indication that the 30-year CMS rate is more or less likely to increase or decrease at any time during the life of your notes. See “Additional Risk Factors Specific to Your Notes — The 30-year CMS Rate is Based on a Hypothetical Interest Rate Swap Referencing 3-month USD LIBOR; U.K. Regulators Will No Longer Persuade or Compel Banks to Submit Rates for Calculation of LIBOR After 2021; Interest Rate Benchmark May Be Discontinued”, “Additional Risk Factors Specific to Your Notes — Recent Regulatory Investigations Regarding Potential Manipulation of ISDAfix May Adversely Affect Your Notes” and “Additional Risk Factors Specific to Your Notes — Regulation and Reform of “Benchmarks”, Including LIBOR and Other Types of Benchmarks, May Cause such “Benchmarks” to Perform Differently Than in the Past, or to Disappear Entirely, or Have Other Consequences Which Cannot be Predicted” for more information relating to the 30-year CMS rate.

You should not take the historical levels of the 30-year CMS rate as an indication of future levels of the 30-year CMS rate. We cannot give you any assurance that the future levels of the 30-year CMS rate will result in your receiving a return on your notes that is greater than the return you would have realized if you invested in a debt security of comparable maturity that bears interest at a prevailing market rate.

Neither we nor any of our affiliates make any representation to you as to the performance of the 30-year CMS rate. Before investing in the offered notes, you should consult publicly available information to determine the levels of the 30-year CMS rate between the date of this prospectus supplement and the date of your purchase of the offered notes. The actual levels of the 30-year CMS rate during the interest periods may bear little relation to the historical levels of the 30-year CMS rate shown below.

The graph below shows the daily historical last levels of the 30-year CMS rate from August 29, 2008 through August 29, 2018. We obtained the last levels in the graph below from Reuters, without independent verification.

SUPPLEMENTAL DISCUSSION OF FEDERAL INCOME TAX CONSEQUENCES

The following section supplements the discussion of U.S. federal income taxation in the accompanying prospectus.

The following section is the opinion of Sidley Austin LLP, counsel to The Goldman Sachs Group, Inc. It applies to you only if you hold your notes as a capital asset for tax purposes. This section does not apply to you if you are a member of a class of holders subject to special rules, such as:

This section is based on the U.S. Internal Revenue Code of 1986, as amended, its legislative history, existing and proposed regulations under the Internal Revenue Code, published rulings and court decisions, all as currently in effect. These laws are subject to change, possibly on a retroactive basis.

United States Holders

This subsection describes the tax consequences to a United States holder. You are a United States holder if you are a beneficial owner of notes and you are:

If you are not a United States holder, this section does not apply to you and you should refer to “— United States Alien Holders” below.

Tax Treatment. The notes will be treated as variable rate debt instruments for U.S. federal income tax purposes. Under this characterization, it is the opinion of Sidley Austin LLP that you should include qualified stated interest (i.e., the interest payments) in ordinary income at the time you receive or accrue such payments, depending on your regular method of accounting for tax purposes.

You will generally recognize capital gain or loss upon the sale, exchange or maturity of your notes in an amount equal to the difference, if any, between the amount of cash you receive at such time and your adjusted basis in your notes. See the discussion under “United States Taxation — Taxation of Debt Securities — United States Holders — Purchase, Sale and Retirement of the Debt Securities” for more information.

You should consult your tax advisor concerning the U.S. federal income tax consequences to you of acquiring, owning, and disposing of the notes, as well as any tax consequences arising under the laws of any state, local, foreign, or other tax jurisdiction and the possible effects of changes in U.S. federal or other tax laws.

If you purchase the notes at a price lower than the original issue price, you will be subject to the rules governing market discount as described under “United States Taxation — Taxation of Debt Securities — United States Holders —

S-16

Market Discount” in the accompanying prospectus. If you purchase the notes at a price higher than the original issue price, you will be subject to the rules governing premium as described under “United States Taxation —Taxation of Debt Securities — United States Holders — Debt Securities Purchased at a Premium” in the accompanying prospectus. The original issue price of your notes is equal to the principal amount of the notes.

United States Alien Holders

If you are a United States alien holder, please see the discussion under “United States Taxation — Taxation of Debt Securities — United States Alien Holders” in the accompanying prospectus for a description of the tax consequences relevant to you. You are a United States alien holder if you are the beneficial owner of the notes and are, for U.S. federal income tax purposes:

Backup Withholding and Information Reporting

Please see the discussion under “United States Taxation — Taxation of Debt Securities — Backup Withholding and Information Reporting” in the accompanying prospectus for a description of the applicability of the backup withholding and information reporting rules to payments made on your notes.

Foreign Account Tax Compliance Act (FATCA) Withholding

Pursuant to Treasury regulations, Foreign Account Tax Compliance Act (FATCA) withholding (as described in “United States Taxation—Taxation of Debt Securities—Foreign Account Tax Compliance Act (FATCA) Withholding” in the accompanying prospectus) will generally apply to obligations that are issued on or after July 1, 2014; therefore, the notes will generally be subject to FATCA withholding. However, according to published guidance, the withholding tax described above will not apply to payments of gross proceeds from the sale, exchange or other disposition of the notes made before January 1, 2019.

S-17

EMPLOYEE RETIREMENT INCOME SECURITY ACT

This section is only relevant to you if you are an insurance company or the fiduciary of a pension plan or an employee benefit plan (including a governmental plan, an IRA or a Keogh Plan) proposing to invest in the notes.

The U.S. Employee Retirement Income Security Act of 1974, as amended (“ERISA”) and the U.S. Internal Revenue Code of 1986, as amended (the “Code”), prohibit certain transactions (“prohibited transactions”) involving the assets of an employee benefit plan that is subject to the fiduciary responsibility provisions of ERISA or Section 4975 of the Code (including individual retirement accounts, Keogh plans and other plans described in Section 4975(e)(1) of the Code) (a “Plan”) and certain persons who are “parties in interest” (within the meaning of ERISA) or “disqualified persons” (within the meaning of the Code) with respect to the Plan; governmental plans may be subject to similar prohibitions unless an exemption applies to the transaction. The assets of a Plan may include assets held in the general account of an insurance company that are deemed “plan assets” under ERISA or assets of certain investment vehicles in which the Plan invests. Each of The Goldman Sachs Group, Inc. and certain of its affiliates may be considered a “party in interest” or a “disqualified person” with respect to many Plans, and, accordingly, prohibited transactions may arise if the notes are acquired by or on behalf of a Plan unless those notes are acquired and held pursuant to an available exemption. In general, available exemptions are: transactions effected on behalf of that Plan by a “qualified professional asset manager” (prohibited transaction exemption 84-14) or an “in-house asset manager” (prohibited transaction exemption 96-23), transactions involving insurance company general accounts (prohibited transaction exemption 95-60), transactions involving insurance company pooled separate accounts (prohibited transaction exemption 90-1), transactions involving bank collective investment funds (prohibited transaction exemption 91-38) and transactions with service providers under Section 408(b)(17) of ERISA and Section 4975(d)(20) of the Code where the Plan receives no less and pays no more than “adequate consideration” (within the meaning of Section 408(b)(17) of ERISA and Section 4975(f)(10) of the Code). The person making the decision on behalf of a Plan or a governmental plan shall be deemed, on behalf of itself and the plan, by purchasing and holding the notes, or exercising any rights related thereto, to represent that (a) the plan will receive no less and pay no more than “adequate consideration” (within the meaning of Section 408(b)(17) of ERISA and Section 4975(f)(10) of the Code) in connection with the purchase and holding of the notes, (b) none of the purchase, holding or disposition of the notes or the exercise of any rights related to the notes will result in a nonexempt prohibited transaction under ERISA or the Code (or, with respect to a governmental plan, under any similar applicable law or regulation), and (c) neither The Goldman Sachs Group, Inc. nor any of its affiliates is a “fiduciary” (within the meaning of Section 3(21) of ERISA) or, with respect to a governmental plan, under any similar applicable law or regulation) with respect to the purchaser or holder in connection with such person’s acquisition, disposition or holding of the notes, or as a result of any exercise by The Goldman Sachs Group, Inc. or any of its affiliates of any rights in connection with the notes, and neither The Goldman Sachs Group, Inc. nor any of its affiliates has provided investment advice in connection with such person’s acquisition, disposition or holding of the notes.
