The estimated value of the securities is based on CGMI’s proprietary pricing models and our internal funding rate.

See “Valuation of the Securities” in the related preliminary pricing supplement.

Investing in the securities involves risks not associated with an investment in conventional debt securities. See “Risk Factors” beginning on page 3 in this term sheet, “Risk Considerations” in the accompanying preliminary pricing supplement and “Risk Factors” in the accompanying prospectus.

This introductory term sheet does not provide all of the information that an investor should consider prior to making an investment decision.

Investors should carefully review the accompanying preliminary pricing supplement, product supplement, underlying supplement prospectus supplement and prospectus before making a decision to invest in the securities.

Hypothetical Examples

The diagram at right illustrates your payment at maturity for a range of hypothetical percentage changes from the initial index level to the final index level. The diagram is based on a hypothetical maximum return at maturity of 37.00%, which is equivalent to a hypothetical maximum return at maturity of $370.00 per security.

Hypothetical Returns

The table below is based on a hypothetical initial index level of 3,649.54 and a hypothetical maximum return at maturity of 37.00%, which is equivalent to a hypothetical maximum return at maturity of $370.00 per security and will be determined on the pricing date. Your actual return will depend on the actual final index level, the actual maximum return at maturity and whether you hold your securities to maturity. The table below is based on a range of hypothetical percentage changes from the initial index level to the final index level and illustrates:

•

the hypothetical percentage change from the hypothetical initial index level to the hypothetical final index level;

•

the hypothetical payment at maturity per security;

•

the hypothetical total pre-tax rate of return; and

•

the hypothetical pre-tax annualized rate of return.

The above figures are for purposes of illustration only and may have been rounded for ease of analysis.

Payment at Maturity

For each $1,000 stated principal amount you hold at maturity:

•

If the final index level is greater than the initial index level:

$1,000 plus the lesser of:

(i) $1,000 × final index level – initial index level × participation rate ; and

initial index level

(ii) the maximum return at maturity

•

If the final index level is less than or equal to the initial index level, but greater than or equal to the buffer level, $1,000

•

If the final index level is less than the buffer level, $1,000 minus:

$1,000 × buffer level – final index level

initial index level

If the final index level is less than the buffer level, you will receive less, and possibly 80% less, than the $1,000 stated principal amount per security at maturity.
