RATINGS RATIONALE

"The review for upgrade of Turkcell's ratings reflects, firstly, our guidance that an upgrade would be linked to an upgrade of Turkey's sovereign rating, which is now Ba1, and, secondly, the company's maintenance of a strong fundamental credit profile," says Martin Kohlhase, a Moody's Vice President -- Senior Analyst and lead analyst for Turkcell. "We have decided to review the ratings for upgrade rather than positioning them in the Ba1 category immediately because, firstly, this will allow us to assess how Turkcell's financial profile develops with regard to a number of potential cash calls that the company could face in the next year," explains Mr. Kohlhase. "Secondly, the review for upgrade will allow us to gauge how well Turkcell's current and evolving financial profile will be able to absorb the anticipated deterioration in the company's key credit metrics, given its slightly increased leverage and the competition in the Turkish market."

Amongst Turkcell's potential cash calls are (i) dividend payouts for financial years 2010 and 2011, which have not yet been declared and paid, but could result in a combined outflow of approximately USD1.063 billion; (ii) potential recapitalisations of any of the company's international subsidiaries in the wake of deteriorating local currencies, financial covenant breaches or weakening operating performances; and (iii) small to medium-sized acquisitions or greenfield investments of up to USD500 million.

WHAT COULD CHANGE THE RATING UP/DOWN

Ratings could also be upgraded if the current strong financial profile is maintained with Debt to EBITDA below 1.5 times, interest cover (FFO and EBITDA-Capex) of at least 7 times and positive free cash flow on a sustainable basis. Should Turkcell spend the bulk of its cash, ratings could reach a higher debt level, provided that the company at the same time establishes sufficiently strong back-stop liquidity, e.g., in the form of a multi-year revolving credit facility.

Were Turkcell to step up its investment and acquisition plans - e.g. new licenses, privatisation bids - or increase shareholder returns with a subsequent weakening of RCF to debt below 35%, debt to EBITDA above 2 times and (EBITDA - Capex) to interest expense of less than 5 times this could exert pressure on both the rating and outlook. Concurrently, Turkcell's rating outlook could be moved back to stable in the event that the Turkish sovereign rating outlook were to be changed to stable.

The principal methodology used in rating Turkcell was the Global Telecommunications Industry Methodology published in December 2010. Please see the Credit Policy page on www.moodys.com for a copy of this methodology.

Turkcell Iletisim Hizmetleri A.S. ("Turkcell"), headquartered in Istanbul, Turkey, and established in 1993, started operations as a mobile telephony service provider in Turkey in 1994 and acquired a 25-year GSM licence in 1998. Today, Turkcell shares its domestic market with two other players and captures more than half of the country's mobile subscriber base. Over the years, Turkcell has expanded into Eastern Europe and Central Asia, where it is active in eight countries, as well as northern Cyprus. Its mobile virtual network operator (MVNO) business in Germany started in the first quarter of 2011. Turkcell also has a growing business in adjacent telephony services such as broadband in Turkey.
