Additional Tier 1 Notes financial

"US$ 1,000,000,000 3.7% Additional Tier 1 Notes (“Bonds”) issued on August 25, 2021"

Call Option financial

"the Bank has elected to exercise the Call Option in respect of the US$ 1,000,000,000"

A call option is a contract that gives its buyer the right, but not the obligation, to buy a specific number of shares at a predetermined price within a set time period. Think of it as a refundable reservation to buy an item later at today’s price: you pay a fee up front and can profit if the stock rises, while your downside is limited to that fee; investors use calls to gain leverage, speculate on upside, or hedge positions without owning the shares.

Redemption Date financial

"On the Redemption Date, the Bonds will be redeemed in full and all rights and obligations"

The redemption date is the specific day when a debt-like security (such as a bond, preferred share, or certificate) must be repaid by the issuer and the investor receives the principal plus any final interest or dividends. It matters to investors because it tells when cash will return, shapes the effective return and price of the security, and creates reinvestment and timing considerations—like knowing when a loan is due so you can plan what to do with the returned money.

Trust Deed financial

"pursuant to the Trust Deed between the Issuer and Citicorp International Limited"

A trust deed is a legal document used to secure a loan with real property: the borrower transfers title to a neutral third-party trustee to hold as collateral until the loan is repaid. It works like handing the house keys to a trusted friend while you pay back the debt, allowing the lender quicker recovery if the borrower defaults. Investors care because a trust deed determines the lender’s priority, speed of foreclosure, and likelihood of recovering funds in a default.

Redemption at the Option of the Issuer financial

"in accordance with Condition 4(b) (Redemption at the Option of the Issuer) of the Terms"

A clause that lets the borrower (the company that issued a bond or preferred share) choose to pay back the security before its stated maturity date. It matters to investors because early repayment changes expected income and timing — like a loan being paid off ahead of schedule — which can lower total returns and force reinvestment at potentially lower interest rates; buyers often demand higher yields or call protection to compensate.
