EBU Single Rulebook Q&A 12 March 2015 2015_1891 The maturity ladder on template AE-CB (F 35.00)

Do institutions need to report the residual maturity of the cover pool assets or the residual maturity of the covered bonds the assets are backing in the maturity ladder of the Cover Pool Assets (C 150-C 200)? There are only interpretations and not a clear specification of which residual maturity is required.
