RISK FACTORS
You should read this entire prospectus supplement and the accompanying prospectus carefully. Words and expressions
defined elsewhere in this prospectus supplement and the accompanying prospectus have the same meanings in this section. Investing
in the notes involves certain risks. In addition, the purchase of the notes may involve substantial risks and be suitable only for
investors who have the knowledge and experience in financial and business matters to enable them to evaluate the risks and merits of
an investment in the notes. You should make your own inquiries as you deem necessary without relying on the Republic or any
underwriter and should consult with your financial, tax, legal, accounting and other advisers, prior to deciding whether to make an
investment in the notes. You should consider, among other things, the following:
Risks Relating to the Notes
The trading market for the notes may be volatile and may be adversely impacted by many events.
The market for the notes is expected to be influenced by economic and market conditions and, to varying degrees, interest
rates, currency exchange rates and inflation rates in the United States and Europe and other countries. There can be no assurance that
events in Turkey, the United States, Europe or elsewhere will not cause market volatility or that such volatility will not adversely
affect the price of the notes or that economic and market conditions will not have any other adverse effect.
There may be no active trading market for the notes.
There can be no assurance that an active trading market for the notes will develop, or, if one does develop, that it will be
maintained. If an active trading market for the notes does not develop or is not maintained, the market or trading price and liquidity of
the notes may be adversely affected. If the notes are traded after their initial issuance, they may trade at a discount to their initial
offering price, depending upon prevailing interest rates, the market for similar securities, general economic conditions and the
financial condition of the Republic. Although an application will be made to list on the Official List and trade the notes on the
Regulated Market "Bourse de Luxembourg" of the Luxembourg Stock Exchange, there is no assurance that such application will be
accepted or that an active trading market will develop.
The notes may not be a suitable investment for all investors.
You must determine the suitability of investment in the notes in the light of your own circumstances. In particular, you
should:
(i) have sufficient knowledge and experience to make a meaningful evaluation of the notes and the merits and risks
of investing in the notes;
(ii) have access to, and knowledge of, appropriate analytical tools to evaluate, in the context of its particular financial
situation, an investment in the notes and the impact the notes will have on your overall investment portfolio;
(iii) have sufficient financial resources and liquidity to bear all of the risks of an investment in the notes, including
where the currency for principal or interest payments is different from your currency;
(iv) understand thoroughly the terms of the notes and be familiar with the behavior of any relevant indices and
financial markets; and
(v) be able to evaluate (either alone or with the help of a financial adviser) possible scenarios for economic, interest
rate and other factors that may affect your investment and your ability to bear the applicable risks.
The notes are unsecured.
The notes constitute unsecured obligations of the Republic.

S-9

The notes contain provisions that permit the Republic to amend the payment terms without the consent of all holders.
The notes contain provisions regarding acceleration and voting on amendments, modifications, changes and waivers, which
are commonly referred to as "collective action clauses". Under these provisions, certain key provisions of the notes may be amended,
including the maturity date, interest rate and other payment terms, with the consent of the holders of 75% of the aggregate principal
amount of the outstanding notes. See "Description of the Notes -- Default; Acceleration of Maturity" and "-- Amendments and
Waivers" in this prospectus supplement and "Debt Securities -- Collective Action Securities Issued Prior to January 1, 2015" in the
accompanying prospectus.
There can be no assurance that the laws of the State of New York in effect as at the date of this prospectus supplement will
not be modified.
The conditions of the notes are based on the laws of the State of New York in effect as at the date of this prospectus
supplement. No assurance can be given as to the impact of any possible judicial decision or change to New York law or administrative
practice after the date of this prospectus supplement.
Legal investment considerations may restrict certain investments.
The investment activities of certain investors are subject to legal investment laws and regulations, or review or regulation by
certain authorities. Prospective investors should consult their legal advisers to determine whether and to what extent: (1) the notes are
legal investments for such prospective investors; (2) the notes can be used as collateral for various types of borrowing; and (3) other
restrictions apply to their purchase or pledge of any notes. Financial institutions should consult their legal advisors or the appropriate
regulators to determine the appropriate treatment of notes under any applicable risk based capital or similar rules.
Risks Relating to the Republic
The Republic is a foreign sovereign state and accordingly it may be difficult to obtain or enforce judgments against it.
The Republic is a sovereign state. Consequently, the ability of noteholders to sue the Republic may be limited.
The Republic has not consented to service or waived sovereign immunity with respect to actions brought against it under
United States federal securities laws or any State securities laws. In the absence of a waiver of immunity by the Republic with respect
to these actions, it would not be possible to obtain judgment in such an action brought against the Republic in a court in the United
States unless the court were to determine that the Republic is not entitled under the Foreign Sovereign Immunities Act to sovereign
immunity with respect to such action. Further, even if a United States judgment could be obtained in such an action, it may not be
possible to enforce in the Republic a judgment based on such a United States judgment. Execution upon property of the Republic
located in the United States to enforce a United States judgment may not be possible except under the limited circumstances specified
in the Foreign Sovereign Immunities Act.
There can be no assurance that the Republic's credit ratings will not change.
Long-term foreign currency debt of the Republic is currently rated BB+ by Standard and Poor's Credit Market Services
Europe Limited ("Standard and Poor's") (which changed the Republic's long-term foreign currency debt rating on March 27, 2013
from BB), Baa3 by Moody's Investors Service Limited ("Moody's") (which changed the Republic's long-term foreign and local
currency rating on May 16, 2013 from Ba1) and BBB- by Fitch Ratings Limited ("Fitch") (which changed the Republic's long-term
foreign currency rating on November 5, 2012 from BB+). On February 7, 2014, Standard & Poor's revised its outlook on the long-
term debt ratings of the Republic to negative from stable (while affirming the BB+ long-term foreign currency sovereign credit rating),
due to perceived increased risks of a hard economic landing in Turkey as external conditions tighten and unfavorable exchange and
interest rate dynamics pose downside risks to GDP forecasts, the country's declining reserve coverage of net external financing needs,
and the view that Turkey's policy environment is becoming less predictable, and that this could weigh on the economy's resilience
and long-term growth potential. On November 6, 2015, Standard & Poor's affirmed the Republic's long-term foreign and local
currency ratings at BB+ and BBB-, respectively, each with a negative outlook. Standard & Poor's indicated that the negative outlook
incorporates the risks of an alternative scenario in which external financing becomes both more expensive and scarcer, and
institutional checks and balances deteriorate further. On April 4, 2014, Moody's changed the outlook on Turkey's Baa3 government
bond rating to negative from stable. Moody's indicated that key drivers of outlook change were: (i) increased pressure on the
