 their interests in debt securities transferred to their own name so that they will be direct holders. The rights of street name investors and direct holders in the debt securities have been previously described in the subsections entitled “ — Street Name and Other Indirect Holders ” and “— Direct Holders ”.

The special situations for termination of a global security are:

•

When the depositary notifies us or Rio Tinto that it is unwilling, unable or ceases to be a clearing agency registered under the Exchange Act.

•

When an event of default on the debt securities has occurred and has not been cured. Defaults are discussed below under “— Default and Related Matters — Events of Default ”.

The prospectus supplement may also list additional situations for terminating a global security that would apply only to the particular series of debt securities covered by the prospectus supplement. When a global security terminates, the depositary (and not we or the trustee) is responsible for deciding the names of the institutions that will be the initial direct holders. ( Section 305 of the Base Indenture )
