Article 478(2) of the CRR provides a discretion to competent authorities to apply a slower phase-in rate for the Deduction of Deferred Tax Assets that rely on Future Profitability for DTAs that existed prior to 1 January 2014. A 10% per annum phase in rate is applied for the DTAs that existed prior to 1 January 2014 while all other DTAs that were created post 1 January 2014 are subject to the normal phase in rates of 20% per annum. Clarification is required on how the different phase-in rates should be applied if the amount of DTAs (that rely on Future Profitability) in existence reduces below the initial amount recognised, due not to progressive deduction under the transition rules but rather due to usage against profit ? For example: Assume on 31 December 2014, the DTA balance is 100 which is made up of 60 that existed pre 1 January 2014 and 40 that existed post 1 January 2014. Assume that on 31 March 2015, the DTA balance reduces to 80 due to usage against profits. Should the DTA balance that existed pre 1 January 2014 be adjusted by the negative balances due to the DTA usage against profits i.e. should the slower phase-in rates be applied to the balance of 40?
