Each security has a $1,000 principal amount and pays a 0.8875% contingent coupon per month (annualized 10.65%) only if, on the relevant valuation date, the worst-performing underlying is at or above its coupon barrier equal to 70% of its initial value.

Citigroup may call the notes in whole on specified potential redemption dates, paying $1,000 plus any due coupon, which can shorten the investment term. If the notes are not redeemed and on the final valuation date the worst-performing underlying is at or above its final barrier (also 70% of initial), investors receive $1,000 plus any final coupon. If it is below the final barrier, repayment is reduced dollar-for-dollar with the index/ETF loss, with no minimum, so investors may lose most or all of principal and may receive no coupons.

The initial underlying values are 2,987.395 for the Russell 2000, 7,509.20 for the S&P 500 and $178.66 for the ETF. The issue price is $1,000, including up to $7.00 in underwriting fees, for total offering proceeds of $3,155,000.00, while the estimated value is $981.40 per note based on internal models and funding rates.
