This procedure ranks potential divergences for their consideration. We apply it to Additional Tier 1 (AT1) prospectuses from European global systemically important banks. We validate the procedure on anonymised documents from Credit Suisse and Yes Bank, recovering rule-prospectus differences that later mattered in disputes over AT1 loss absorption. This procedure could support other supervisory comparisons, including reviews of national rules against the international standards they implement.
