Artículo B7.2.2. IFRS 9 Paragraph B7.2.2

On transition, an entity should seek to approximate the credit risk on initial recognition by considering all reasonable and supportable information that is available without undue cost or effort. An entity is not required to undertake an exhaustive search for information when determining, at the date of transition, whether there have been significant increases in credit risk since initial recognition. If an entity is unable to make this determination without undue cost or effort paragraph 7.2.20 applies.
