The NYSE Arca will suspend trading in the shares of the Trusts before the open of trading on March 26, 2012. Beginning that day and continuing until 4:00 p.m. Eastern Time on June 25, 2012, holders may tender their shares in the Trust through the facilities of the Depository Trust Company (“DTC”) to The Bank of New York Mellon, as trustee of each Trust (the “Trustee”). Upon receipt by the Trustee of a tendering holder’s shares together with wire instructions for an authorized account that may lawfully accept deposits of the underlying foreign currency and payment by or for the holder of any transaction fees, charges and taxes, the Trustee will deliver the amount of underlying foreign currency represented by such shares.

The Trustee has advised the Sponsor that, commencing June 26, 2012, the Trustee will sell any remaining trust property in each Trust for United States Dollars. The Trustee will make a final distribution to DTC on the remaining outstanding shares in United States Dollars on June 29, 2012.

Transaction costs incurred by a Trust in terminating the Trust will be reflected in each Trust’s net asset value and can be expected to diminish the amount of currency received by shareholders.

On or about March 26, 2012, the Sponsor intends to file with the Securities and Exchange Commission (“SEC”), on behalf of each Trust, a Form 15 to voluntarily deregister the Shares and suspend reporting obligations under the Securities Exchange Act of 1934, as amended. Each Trust’s duty to file periodic reports with the SEC will be suspended immediately upon the filing of the Form 15. The Sponsor expects that deregistration of the shares of each Trust will become effective 90 days after that filing.

The CurrencyShares^® Mexican Peso Trust and the CurrencyShares^® Russian Ruble Trust (the “Trusts”) have each filed a registration statement (including a prospectus) with the SEC for the offerings to which this communication relates. Before you invest in the shares of a Trust, you should read the prospectus in the registration statement and other documents the Trust has filed with the SEC for more complete information about the Trust and its offering.
