, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date H.15 TCM is no longer published, we, Rio Tinto or any other designated agent shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m. (New York City time), on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the relevant Par Call Date, as applicable (and in the case of the 2027 Notes, the maturity date of the 2027 Notes). If there is no United States Treasury security maturing on the relevant Par Call Date (and in the case of the 2027 Notes, the maturity date of the 2027 Notes) but there are two or more United States Treasury securities with a maturity date equally distant from the relevant Par Call Date (and in the case of the 2027 Notes, the maturity date of the 2027 Notes), one with a maturity date preceding the relevant Par Call Date (and in the case of the 2027 Notes, the maturity date of the 2027 Notes) and one with a maturity date following the relevant Par Call Date (and in the case of the 2027 Notes, the maturity date of the 2027 Notes), we, Rio Tinto or any other designated agent shall select the United States Treasury security with a maturity date preceding the relevant Par Call Date (and in the case of the 2027 Notes, the maturity date of the 2027 Notes).

In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury
