Floating Rate Notes financial
"Senior Non Preferred Floating Rate Notes due 2029"
Floating rate notes are debt securities that pay interest that adjusts periodically based on a short-term interest benchmark (for example, LIBOR or SOFR), so the cash interest you receive goes up or down with market rates. For investors they act like an adjustable-rate loan: they help protect income when overall interest rates rise and generally lose less value than fixed-rate bonds when rates move, making them useful for managing interest-rate risk.
Indenture financial
"Senior Non Preferred Debt Securities Indenture, dated as of April 15, 2026"
An indenture is a legal agreement between a company that borrows money by issuing bonds and the people who buy those bonds. It explains the rules the company must follow, like paying back the money and keeping certain financial promises. This document helps both sides understand their rights and responsibilities.
First Supplemental Indenture financial
"First Supplemental Indenture, dated as of April 15, 2026"
Registration Statement on Form F-3 regulatory
"solely for incorporation into the Registration Statement on Form F-3"
A registration statement on Form F-3 is a streamlined filing used by eligible foreign companies to register securities for sale in the U.S., often as a “shelf” that lets them offer shares quickly when market conditions are right. For investors it matters because it signals that the company can raise capital on short notice—potentially increasing liquidity but also the risk of share dilution if new stock is issued—similar to a company keeping a pre-approved credit line ready to use.
