В статье рассматривается методология построения и валидации модели EAD (Exposure at Default) – ключевого компонента системы оценки кредитного риска наряду с PD (Probability of Default) и LGD (Loss Given Default). Представлены основные этапы расчета коэффициента конверсии кредитного лимита (CCF), выявлены проблемы классической методологии и предложен модифицированный подход, повышающий стабильность и интерпретируемость модели. Показано, что использование устойчивого расчета CCF позволяет применять интерпретируемые модели, соответствующие требованиям Банка России и международным стандартам.</p></abstract><trans-abstract xml:lang="en"><p>In connection with the reform of credit risk regulation, the Bank of Russia has established that all systemically important credit institutions should switch to an internal ratings approach by January 1, 2030. The article discusses the methodology for constructing and validating the EAD (Exposure at Default) model, a key component of the credit risk assessment system along with PD (Probability of Default) and LGD (Loss Given Default). The main stages of calculating the credit limit conversion rate (CCF) are presented, the problems of the classical methodology are identified, and a modified approach is proposed that increases the stability and interpretability of the model. It is shown that the use of stable CCF calculation makes it possible to apply interpretable models that meet the requirements of the Bank of Russia and international standards.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кредитный риск</kwd><kwd>IRB</kwd><kwd>EAD-модель</kwd><kwd>CCF</kwd><kwd>валидация</kwd><kwd>Банк России</kwd><kwd>Basel II</kwd><kwd>риск-менеджмент</kwd></kwd-group><kwd-group xml:lang="en"><kwd>credit risk</kwd><kwd>IRB</kwd><kwd>EAD model</kwd><kwd>CCF</kwd><kwd>validation</kwd><kwd>Bank of Russia</kwd><kwd>Basel II</kwd><kwd>risk management</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Бобров 2011 – Бобров Д.В.
