AT1

Additional Tier 1 instruments

Additional Tier 1 instruments are perpetual, deeply subordinated bonds that count as going-concern capital: they convert into equity or are written down automatically once a bank's Common Equity Tier 1 ratio falls through a contractual trigger, and coupons can be cancelled at any time at the issuer's discretion.

AT1 sits immediately behind ordinary shares. It is the first layer of debt to absorb losses, whether through its contractual trigger, through the write-down and conversion power at the point of non-viability, or in a bail-in. Full definition in the glossary.

Notional is summed over EUR-denominated lines that report an amount. FIRDS carries no exchange rates, so amounts in other currencies are counted but never converted.

Largest issuers

By number of live instruments. Issuance count is not issuance volume — a bank running a large medium-term note programme shows many small lines.
