Article 104a 2.

Competent authorities shall grant permission to reclassify a trading book position as a non-trading book position or conversely a non-trading book position as a trading book position for the purpose of determining their own funds requirements only where the institution has provided the competent authorities with written evidence that its decision to reclassify that position is the result of an exceptional circumstance that is consistent with the policies the institution has in place in accordance with paragraph 1 of this Article. For that purpose, the institution shall provide sufficient evidence that the position no longer meets the condition to be classified as a trading book or non-trading book position pursuant to Article 104.
