Examples of Payment at Maturity Calculations
 
Set forth below are three hypothetical examples of Payment at Maturity calculations (rounded to two decimal places), reflecting the following values and hypothetical data:
 
 
·
the Minimum Payment per Security of $1,000;
 
 
·
the Participation Rate of 100%; and
 
 
·
the Initial Value of 112.70.
 
Any payment at maturity is subject to the ability of RBS, as the issuer of the securities, and RBSG, as the guarantor of the issuer’s obligations under the securities, to pay their respective obligations as they become due.
 
EXAMPLE 1 — The hypothetical Final Value is 78.89 (which is 30% below the Initial Value):
 
Reference Return
=
78.89 – 112.70
=
-30%
112.70
 
Payment at Maturity (per security) will be equal to the greater of:
 
(a) $1,000 (the Minimum Payment per Security); and
 
(b) $1,000 + ($1,000 x -30%) = $700.
 
Payment at Maturity (per security) = $1,000 (i.e., a 100% repayment of principal).
 
The Payment at Maturity is equal to the Minimum Payment per Security of $1,000 (100% of the Original Offering Price).
 
EXAMPLE 2 — The hypothetical Final Value is 146.51 (which is 30% above the Initial Value):
 
Reference Return
=
146.51 – 112.70
=
30%
112.70
 
Payment at Maturity (per security) will be equal to:
 
$1,000 + ($1,000 x 100% x 30%) = $1,300.
 
Payment at Maturity (per security) = $1,300 (i.e., a 30% return).
 
EXAMPLE 3 — The hypothetical Final Value is 169.05 (which is 50% above the Initial Value):
 
Reference Return
=
169.05 – 112.70
=
50%
112.70
 
Payment at Maturity (per security) will be equal to:
 
$1,000 + ($1,000 x 100% x 50%) = $1,500.00.
 
Payment at Maturity (per security) = $1,500.00 (i.e., a 50% return).

Hypothetical Payout Profile and Payment at Maturity
 
For purposes of illustration only, the Hypothetical Payout Profile and Hypothetical Payment at Maturity below reflect the hypothetical returns at maturity and hypothetical payments at maturity per security for a range of hypothetical Final Values of the Underlying Equity Fund from +100% to -100%.  The hypothetical Final Values presented below will not include any income generated by dividends paid on the units of the Underlying Equity Fund, which you would otherwise be entitled to receive if you invested in those units directly.
 
The graph and chart reflect the Participation Rate of 100%, the Initial Value of 112.70, and the Minimum Payment per Security of $1,000.  The actual Payment at Maturity that you are entitled to receive and the resulting return on your investment will depend on the actual Final Value, which will be determined on the Valuation Date.
 
Any payment at maturity is subject to the ability of RBS, as the issuer of the securities, and RBSG, as the guarantor of the issuer’s obligations under the securities, to pay their respective obligations as they become due.
 
HYPOTHETICAL PAYOUT PROFILE
 
 
This graph reflects the hypothetical returns on the securities at maturity.  The green line reflects the hypothetical returns on the securities, while the dotted line reflects the return of a hypothetical direct investment in the Underlying Equity Fund, excluding dividends.

Risk Factors
 
There are important differences between the securities and a conventional debt security.  An investment in the securities involves significant risks, including those listed below.  You should carefully review the more detailed explanation of risks relating to the securities in the “Risk Factors” sections beginning on page S-14 of the product supplement.  We also urge you to consult with your investment, legal, accounting, tax, and other advisors before you invest in the securities.
 
·
The securities are not conventional debt securities—they do not pay interest.
 
·
The credit risk of The Royal Bank of Scotland plc and The Royal Bank of Scotland Group plc, and their credit ratings and credit spreads may adversely affect the value of the securities.
 
·
The Payment at Maturity will depend on the Final Value, which is determined only on a valuation date shortly before the maturity date.
 
·
The securities may not be a suitable investment for you.
 
·
Although we are a bank, the securities are not bank deposits and are not insured or guaranteed by the Federal Deposit Insurance Corporation, the Deposit Insurance Fund or any other government agency.
 
·
The securities will not be listed on any securities exchange and there may be little or no secondary market for the securities.
 
·
The value of the securities prior to maturity will be influenced by many unpredictable factors, and may be less than the Original Offering Price.
 
·
In the event that we or RBSG, as guarantor, exercise our option to redeem the securities, as described in the section of the product supplement entitled “Description of the Securities—Optional Tax Redemption,” the amount of cash you will be entitled to receive upon redemption of the securities is uncertain.
 
·
An increase in the price per unit of the Underlying Equity Fund may not increase the value of your securities.
 
·
The value of your securities on the pricing date is less than the Original Offering Price due to the underwriting discount and our cost of hedging, both of which can be expected to be reflected in secondary market prices.
 
·
Hedging and trading activities by us or our affiliates may adversely affect your return on the securities and the value of the securities.
 
·
The holding of securities by our affiliates and future sales by our affiliates could be in conflict with your interests.
 
·
There may be potential conflicts of interest between security holders and the calculation agent or other of our affiliates.
 
·
RBSSI and its affiliates may publish reports, express opinions or provide recommendations that are inconsistent with investing in or holding the securities.  Any such reports, opinions or recommendations could affect the value of the Underlying Equity Fund and/or the securities held by the Underlying Equity Fund and therefore the value of the securities.
 
·
An investment in the securities is not the same as a direct investment in the Underlying Equity Fund or in the securities that comprise the Underlying Equity Fund.
 
·
Adjustments to the Underlying Equity Fund could adversely affect the securities.
 
·
We may engage in business with or involving one or more of the issuers of the securities comprising the Underlying Equity Fund or Target Index without regard to your interests.
 
·
We do not control the Underlying Equity Fund or any issuer whose securities comprise the Target Index and we are not responsible for any of their disclosure.
 
·
There may be limited anti-dilution protection.
 
·
The policies of the investment manager for the Underlying Equity Fund could affect the value of the securities.
 
·
There are risks associated with the specific Underlying Equity Fund to which your securities are linked.
 
·
The Underlying Equity Fund may not always be able exactly to replicate the performance of the Target Index.
 
·
The return of the Underlying Equity Fund will be reduced by its expense ratio.

Investor Considerations
 
You may wish to consider an investment in the securities if:
 
·
You anticipate that the price per unit of the Underlying Equity Fund will increase from the Initial Value to the Final Value.
 
·
You do not seek a current income stream from your investment.
 
·
You are willing to forgo interest payments on the securities such as fixed or floating rate interest paid on traditional interest bearing debt securities.
 
·
You seek exposure to the performance of the Underlying Equity Fund with no expectation of dividends or other benefits of owning the securities comprising the Underlying Equity Fund or Target Index.
 
·
You are willing to accept that a trading market is not expected to develop for the securities and you understand that secondary market prices for the securities, if any, will be affected by various factors, including our actual and perceived creditworthiness.
 
·
You are able to and willing to hold the securities until maturity.
 
·
You are willing to make an investment, the payments on which depend on the creditworthiness of RBS, as the issuer of the securities, and RBSG, as the guarantor of the issuer’s obligations under the securities.
 
The securities may not be an appropriate investment for you if:
 
·
You are not willing to be exposed to the performance of the Underlying Equity Fund.
 
·
You believe that the price per unit of the Underlying Equity Fund will not increase sufficiently over the term of the securities to provide you with your desired return.
 
·
You seek interest payments or other current income on your investment.
 
·
You want to receive dividends or other distributions paid on the securities included in the Underlying Equity Fund or Target Index.
 
·
You seek assurances that there will be a liquid market if and when you want to sell the securities prior to maturity.
 
·
You are unwilling or are unable to assume the credit risk associated with RBS, as the issuer, and RBSG, as the guarantor of the issuer’s obligations under the securities.

The Underlying Equity Fund
 
We have derived all information contained in this document regarding the SPDR® Dow Jones Industrial AverageSM ETF Trust (the “Trust”), including, without limitation, its make-up, method of calculation and changes in its components, from publicly available information.  According to publicly available information, the Trust is an exchange-traded fund designed to generally correspond, before expenses, to the price and yield performance of the Dow Jones Industrial AverageSM (the “DJIA”).  The Trust currently has an expense ratio of approximately 0.18% per year.
 
The Trust is a unit investment trust created under the laws of the State of New York and is governed by a trust agreement (the “Trust Agreement”) between State Street Bank and Trust Company, as trustee (the “Trustee”) and PDR Services LLC, as sponsor (the “Sponsor”).  The Trust is an investment company registered under the Investment Company Act of 1940, as amended.  The Trust was created to provide investors with the opportunity to purchase units of beneficial interest in the Trust representing proportionate undivided interests in the portfolio of securities consisting of substantially all of the component common stocks that comprise the DJIA (such common stocks, the “Index Securities”).  Each unit of fractional undivided interest in the Trust is referred to as a “Unit”.  Individual Units are listed for trading on the NYSE Arca, Inc. (“NYSE Arca”) and are bought and sold in the secondary market like ordinary shares of stock at any time during the trading day.  Units are traded on the NYSE Arca in 100 Unit round lots, but can be traded in odd lots of as little as one Unit.  The Trust commenced operations on January 14, 1998 upon the initial issuance of 500,000 Units in exchange for a portfolio of securities assembled to reflect the intended portfolio composition of the Trust.
 
Information provided to or filed with the Commission by the Trust pursuant to the Securities Act of 1933, as amended, and the Investment Company Act of 1940 can be located by reference to Commission file numbers 333-31247 and 811-09170, respectively, through the SEC’s website at http://www.sec.gov.  Information from outside sources is not incorporated by reference in, and should not be considered a part of, this pricing supplement.  We make no representation or warranty as to the accuracy or completeness of such information.  In addition, information may be obtained from other sources including, but not limited to, press releases, newspaper articles and other publicly disseminated documents.  As a prospective purchaser of securities, you should undertake an independent investigation of the Trust as in your judgment is appropriate to make an informed decision with respect to an investment linked to the Trust.
 
Composition of the Trust

Because the objective of the Trust is to provide investment results that, before expenses, generally correspond to the price and yield performance of the DJIA, the composition and weightings of stocks held by the Trust (each a “Portfolio Security” and collectively, the “Portfolio”) at any time will consist of as many of the Index Securities as is practicable.  It is anticipated that cash or cash items (other than dividends held for distribution) normally would not be a substantial part of the Trust’s net assets.  Although the Trust may at any time fail to own certain of the Index Securities, the Trust will be substantially invested in the Index Securities and the Sponsor believes that such investment should result in a close correspondence between the investment performance of the DJIA and that derived from ownership of Units.  Current information regarding the value of the DJIA is available from market information services.  Dow Jones & Company, Inc. (“Dow Jones”) obtains information for inclusion in, or for use in the calculation of, the DJIA from sources Dow Jones considers reliable.
 
The Trust holds the Portfolio and cash and is not actively “managed” by traditional methods, which would typically involve effecting changes in the Portfolio on the basis of judgments made relating to economic, financial and market considerations.  To maintain the correspondence between the Portfolio and the Index Securities, the Trustee adjusts the Portfolio from time to time to conform to periodic changes in the identity and/or relative weightings of the Index Securities.  The Trustee directs its stock transactions only to brokers or dealers, which may include affiliates of the Trustee, from whom it expects to obtain the most favorable prices or execution of orders.  Adjustments are made more frequently in the case of significant changes to the DJIA.  Specifically, the Trustee is required to adjust the composition of the portfolio whenever there is a change in the identity of any Index Security (i.e., a substitution of one security for another) within three (3) business days before or after the day on which the change is scheduled to take effect.  While other changes to the DJIA may lead to adjustments in the Portfolio, the most common changes are likely to occur as a result of changes in the Index Securities included in the DJIA and as a result of stock splits.  The Trust Agreement sets forth the method of adjustments which may occur thereunder as a result of corporate actions to the DJIA, such as stock splits or changes in the identity of the component stocks.

The value of Trust Units fluctuates in relation to changes in the value of the Portfolio.  The market price of each individual Unit may not be identical to the net asset value (“NAV”) of such Unit.

The Dow Jones Industrial AverageSM
 
We have derived all information relating to the DJIA, including, without limitation, its make-up, performance, method of calculation and changes in its components, from publicly available sources.  That information reflects the policies of and is subject to change by, CME Group Index Services LLC (“CME”).  CME is under no obligation to continue to publish, and may discontinue or suspend the publication of the DJIA at any time.
 
In March 2010, CME Group Inc. and Dow Jones announced the launch of a new joint venture company, CME Group Index Services LLC.  CME Group Inc. has a 90% ownership interest and Dow Jones has a 10% ownership interest in CME, which continues to do business as Dow Jones Indexes and publish the DJIA.
 
Composition of the DJIA
 
The DJIA is a price-weighted index of 30 blue-chip stocks that represent various economic sectors.
 
According to CME, the composition of the DJIA is determined by the “Averages Committee,” comprised of the managing editor of The Wall Street Journal, the head of Dow Jones Indexes research and the head of CME Group Inc. research.  There are no pre-determined criteria except that components should be established U.S. companies that are leaders in their respective industries.  In selecting a company’s stock to be included in the DJIA, the Averages Committee looks for a leading industrial company with a successful history of growth and a wide interest among investors.  The inclusion of any particular company in the DJIA does not constitute a prediction as to the company’s future results of operations or stock market performance.  For the sake of continuity, changes to the composition of the DJIA are rare, and generally occur only after corporate acquisitions or other dramatic shifts in a component’s core business.  When such an event necessitates that one component be replaced, the composition of the entire DJIA is reviewed.  As a result, multiple component changes are often implemented simultaneously.
 
The DJIA does not reflect the payment of dividends on the stocks included in the DJIA.
 
Computation of the DJIA
 
The DJIA is a price-weighted index rather than market capitalization-weighted index.  Thus, the weightings of the components of the DJIA are affected only by changes in their prices, while the weightings of stocks in other indices are affected by price changes and changes in shares outstanding.
 
The DJIA is calculated by adding up the prices of the 30 constituent stocks and dividing the total by a divisor.  The divisor is adjusted to ensure the continuity of the DJIA.  The divisor is now an arbitrary number that reflects adjustments over time resulting from spin-offs, stock splits, stock dividends and other corporate actions, as well as additions to and deletions from the DJIA.  Accordingly, the divisor is no longer equal to the number of components in the DJIA.
 
The formula for calculating a divisor change is as follows:
 
Dt+1 =D t * Σ C a t / Σ C t
Where:
 
Dt+1 is the divisor to be effective on trading session t+1
 
Dt is the divisor on trading session t
 
Ca t is the closing price of an Index Security on trading session t, adjusted for stock dividends, splits, spin-offs and other applicable corporate actions on trading session t
 
Ct is the unadjusted closing price of an Index Security on trading session t
 
While CME currently employs the above methodology to calculate the DJIA, no assurance can be given that CME will not modify or change this methodology in a manner that may affect the performance of the DJIA.

Summary Tax Consequences
 
You should review carefully the section in the accompanying product supplement entitled “U.S. Federal Income Tax Consequences.” The securities should be treated for U.S. federal income tax purposes as “contingent payment debt instruments,” and the discussion that follows assumes this treatment.
 
Interest accruals.  Regardless of your method of accounting, you will be required to accrue interest in each year on a constant yield to maturity basis at the “comparable yield,” as determined by us, although we will not make any payment with respect to the securities until maturity. The comparable yield generally is the yield at which, in similar general market conditions, we could issue a fixed-rate debt instrument with terms similar to those of the securities, including the level of subordination, term and timing of payments, but excluding any adjustments for the riskiness of the contingencies or the liquidity of the securities.
 
Sale, exchange or retirement.  Upon a sale, exchange or retirement of a security (including at maturity), you will recognize income or loss equal to the difference between the amount you receive and your tax basis in the security. Your tax basis in a security will equal its cost, increased by the amount of interest income you have accrued.  Accordingly, at maturity your tax basis will equal the projected payment discussed below.  Income recognized upon a sale, exchange or retirement of the securities (including at maturity) will be treated as interest income.  Any loss will be treated first as ordinary loss, to the extent of previous interest inclusions, and then as capital loss.
 
Comparable yield and projected payment schedule.  The comparable yield is an annual rate of 3.500%, compounded semiannually.  Based on this comparable yield, the “projected payment schedule” per $1,000 security consists of a single payment at maturity, equal to $1,169.12.  Assuming a semiannual accrual period, the following table sets out the amount of interest that will accrue with respect to a security during each calendar year, based upon this comparable yield and the corresponding projected payment schedule:

Calendar Period
Accrued Interest
During Calendar
Period (Per $1,000 Security)
Total Accrued Interest from
Issue Date (Per $1,000 Security) as of End of Calendar Period
8/31/11 through 12/31/11
$11.70
$11.70
1/1/12 through 12/31/12
$35.72
$47.42
1/1/13 through 12/31/13
$36.98
$84.40
1/1/14 through 12/31/14
$38.29
$122.69
1/1/15 through 12/31/15
$39.64
$162.33
1/1/16 through 3/1/16
$6.78
$169.12
 
Neither the comparable yield nor the projected payment schedule constitutes a representation by us regarding the actual amount that we will pay on the securities.  The amount you actually receive upon disposition or retirement of your securities will affect your income for that year, as described above under “Sale, exchange or retirement.”
 
For a discussion of U.K. tax considerations relating to the securities, you should refer to the section in the accompanying product supplement entitled “Taxation in the United Kingdom.”

We do not provide any advice on tax matters. You should consult your tax adviser regarding the U.S. federal tax consequences of an investment in the securities, as well as tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

RBSSI is an affiliate of ours and RBSG.  RBSSI will conduct this offering in compliance with the requirements of Rule 5121 of the Financial Industry Regulatory Authority, Inc., which is commonly referred to as FINRA, regarding a FINRA member firm’s distribution of the securities of an affiliate.  Following the initial distribution of any of these securities, RBSSI may offer and sell those securities in the course of its business as a broker-dealer.  RBSSI may act as principal or selling agent in those transactions and will make any sales at varying prices related to prevailing market prices at the time of sale or otherwise.  RBSSI may use this pricing supplement and the accompanying prospectus and product supplement, in connection with any of those transactions.  RBSSI is not obligated to make a market in any of these securities and may discontinue any market-making activities at any time without notice.
 
We and our affiliates, including RBSSI, may enter into one or more hedging transactions in connection with this offering of securities.  See “Use of Proceeds; Hedging” in the accompanying product supplement.

Four Categories of RBS Investor Products
 
RBS Investor Products is the brand name for RBS’s securities offerings that provide market-driven investment solutions across different asset classes and investor risk profiles to help meet your portfolio needs.  RBS Investor Products are divided into four broad categories depending on the level of risk to your principal invested at maturity:  Protection, Fixed Buffer, Contingent Buffer and Full Exposure.  These broad categories are intended to help you to first understand the degree of your principal at risk at maturity, before you consider the upside potential of RBS Investor Products.  The following description is only an overview of the four categories of RBS Investor Products, and does not represent any particular security nor guarantee performance.  All payments due on RBS Investor Products are subject to the credit risk of RBS, as the issuer, and RBSG, as the guarantor of the issuer’s obligations under the securities.
 
Protection investments provide for full or partial protection on your invested principal at maturity against downside market movements, subject to the creditworthiness of the issuer and the guarantor.  These securities are designed for investors who place a priority on the preservation of principal at maturity, while potentially offering better returns than traditional fixed income investments.  These securities tend to have a longer term than securities that do not offer protection, and principal invested is not protected prior to maturity.
 
Fixed Buffer investments provide a modest buffer at maturity against downside market movements.  These securities are designed for investors who seek potential growth or income, and who also seek some cushion against modest market declines up to a specified buffer.  You are exposed to the full market decline in the underlying asset beyond the specified buffer, and you can lose some or a substantial portion of your investment.
 
Contingent Buffer investments provide some protection against downside market movements only if the underlying asset does not fall to or below a specified level during the term of the securities.  If the underlying asset falls to or below this specified level, you are exposed to the full market decline in the underlying asset at maturity without any cushion against downside market movements.  These investments are for more aggressive investors who can tolerate full downside risk but find the contingent buffer to be an appealing form of tactical cushion.  You can lose some or all of your investment.
 
Full Exposure investments expose investors to full downside risk to any decline in the underlying asset.  These investments are meant for investors who are willing to take full market risk in return for either enhanced appreciation or access to a unique underlying asset or strategy.  You can lose some or all of your investment.
 
RBS Investor Products can provide access to a range of asset classes and risk and potential return profiles.  These investments can play an important role as a portion of a diversified investment portfolio.  In assessing the potential return of any RBS Investor Product, you should understand that these securities involve significant investment risks, and you should carefully review the applicable pricing supplement, product supplement and prospectus before investing.
