This prospectus supplement addendum relates to $25,000,000 principal amount of notes, which we call the “reopened notes,” which are being initially offered on the date of this prospectus supplement addendum.  $25,000,000 principal amount of the notes, which we call the “original notes,” were issued on January 13, 2015, as described in the accompanying prospectus supplement no. 3424 dated January 6, 2015.  The original notes and the reopened notes have identical terms and conditions and have the same CUSIP (38148L148) and ISIN (US38148L1483) numbers. In this prospectus supplement addendum, the term “notes” means, collectively, the reopened notes and the original notes.

The following information supplements, and should be read with, the accompanying prospectus supplement no. 3424 dated January 6, 2015, the accompanying prospectus supplement dated September 15, 2014 and the accompanying prospectus dated September 15, 2014.

Your investment in the notes involves certain risks, including, among other things, our credit risk.  See page S-6 of the accompanying prospectus supplement no. 3424 dated January 6, 2015.  You should read the additional disclosure regarding the terms of the notes, risk factors and the index in the accompanying prospectus supplement no. 3424 so that you may better understand the risks of your investment.

The estimated value of your notes at the time the terms of the reopened notes were set on the trade date for the reopened notes (as determined by reference to pricing models used by Goldman, Sachs & Co. (GS&Co.) and taking into account our credit spreads) was equal to approximately $992 per $1,000 face amount, which is less than the original issue price.  The value of your notes at any time will reflect many factors and cannot be predicted.

We may decide to sell additional notes after the date the reopened notes were traded (January 20, 2015) 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 the notes will depend in part on the issue price you pay for such notes.

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 supplement addendum, the accompanying prospectus supplement no. 3424, the accompanying prospectus supplement or the accompanying 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.

The Index

The TOPIX, also known as the Tokyo Stock Price Index, is a capitalization weighted index of all the domestic common stocks listed on the First Section of the Tokyo Stock Exchange, Inc., which we refer to as the TSE.  Domestic stocks admitted to the TSE are assigned either to the TSE First Section Index, the TSE Second Section Index or the TSE Mothers Index.  Stocks listed in the First Section, which number approximately 1,700, are among the most actively traded stocks on the TSE.  The TOPIX is calculated and published by TSE. Additional information about the TOPIX is available on the following website: http://www.tse.or.jp/english/market/topix/index.html.   We are not incorporating by reference the website or any material it includes in this prospectus supplement addendum.

As of December 31, 2014, the 33 industry sectors which comprise the TOPIX Index represent the following weights in the index:

* Sector designations are determined by the index sponsor using criteria it has selected or developed. Index sponsors may use very different standards for determining sector designations. In addition, many companies operate in a number of sectors, but are listed in only one sector and the basis on which that sector is selected may also differ. As a result, sector comparisons between indices with different index sponsors may reflect differences in methodology as well as actual differences in the sector composition of the indices.

** Information provided by TSE. Percentages may not sum to 100% due to rounding.

The above information supplements the description of the TOPIX found in the accompanying prospectus supplement no. 3424.

Historical Closing Levels of the Index

The closing level of the index has fluctuated in the past and may, in the future, experience significant fluctuations.  Any historical upward or downward trend in the closing level of the index during the period shown below is not an indication that the index is more or less likely to increase or decrease at any time during the life of your notes.

You should not take the historical closing levels of the index as an indication of the future performance of the index.  We cannot give you any assurance that the future performance of the index or the index stocks will result in your receiving an amount greater than the outstanding face amount of your notes on the stated maturity date.

Neither we nor any of our affiliates make any representation to you as to the performance of the index.  Before investing in the offered notes, you should consult publicly available information to determine the relevant index levels between the date of this prospectus supplement and the date of your purchase of the offered notes.  The actual performance of the index over the life of the offered notes, as well as the payment amount at maturity may bear little relation to the historical levels shown below.

The graph below shows the daily historical closing levels of the index from January 20, 2005 through January 20, 2015. We obtained the closing levels in the graph below from Bloomberg Financial Services, without independent verification.

Supplemental Plan of Distribution

The Goldman Sachs Group, Inc. has agreed to sell to Goldman, Sachs & Co., and Goldman, Sachs & Co. has agreed to purchase from The Goldman Sachs Group, Inc., the aggregate face amount of the reopened notes specified above.  Goldman, Sachs & Co. proposes initially to offer the reopened notes to the public at the original issue price specified above, and to certain securities dealers at such prices less a concession not in excess of 0.22% of the face amount of the reopened notes.

The Goldman Sachs Group, Inc. estimates that its share of the total offering expenses for the reopened notes, excluding underwriting discounts and commissions, will be approximately $5,000.

We will deliver the reopened notes against payment therefor in New York, New York on January 27, 2015, which is the fifth scheduled business day following the date of this prospectus supplement addendum and of the pricing of the reopened notes.  Under Rule 15c6-1 of the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the reopened notes on any date prior to three business days before delivery will be required, by virtue of the fact that the reopened notes are initially expected to settle in five business days (T + 5), to specify alternative settlement arrangements to prevent a failed settlement.

We have been advised by Goldman, Sachs & Co. that it intends to make a market in the notes. However, neither Goldman, Sachs & Co. nor any of our other affiliates that makes a market is obligated to do so and any of them may stop doing so at any time without notice. No assurance can be given as to the liquidity or trading market for the notes.
