Notes to Financial Statements
(Unaudited)

1. Organization and Description of the Trust

The CurrencySharesSM Mexican Peso Trust (the “Trust”) was formed under the laws of the State of New York on June 8, 2006 when Rydex Specialized Products LLC d/b/a “Rydex Investments” (the “Sponsor”) deposited 1,000 Mexican Peso in the Trust’s primary deposit account held by JPMorgan Chase Bank N.A., London Branch (the “Depository”). The Sponsor is a Delaware limited liability company whose sole member is PADCO Advisors II, Inc. (also d/b/a “Rydex Investments”). The Sponsor is responsible for, among other things, overseeing the performance of The Bank of New York (the “Trustee”) and the Trust’s principal service providers, including the preparation of financial statements. The Trustee is responsible for the day-to-day administration of the Trust.

The investment objective of the Trust is for the Trust’s shares (the “Shares”) to reflect the price of the Mexican Peso plus accrued interest less the Trust’s expenses and liabilities. The Shares are intended to provide investors with a simple, cost-effective means of gaining investment benefits similar to those of holding Mexican Pesos. The Trust’s assets primarily consist of Mexican Pesos on demand deposit in two deposit accounts maintained by the Depository: a primary deposit account which earns interest and a secondary deposit account which does not earn interest. The secondary deposit account is used to account for interest received and paid out on creations and redemptions of blocks of 50,000 Shares (“Baskets”). The secondary account is also used to account for interest earned on the primary deposit account, pay Trust expenses and distribute any excess interest to holders of Shares (“Shareholders”) on a monthly basis.

The accompanying unaudited financial statements were prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions for Form 10-Q. In the opinion of management, all material adjustments, consisting only of normal recurring adjustments, considered necessary for a fair statement of the interim period financial statements have been made. Interim period results are not necessarily indicative of results for a full-year period. These financial statements and the notes thereto should be read in conjunction with the Trust’s financial statements included in the Form 10-K as filed on January 29, 2008.

2. Significant Accounting Policies

A. Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of the assets, liabilities and disclosures of contingent liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the period. Actual results could differ from those estimates.

6


B. Foreign Currency Translation

The Trustee calculates the Trust’s net asset value (“NAV”) each business day, as described in Note 4. For NAV calculation purposes, Mexican Peso Deposits (cash) are translated at the Noon Buying Rate, which is the U.S. Dollar (“USD”)/ Mexican Peso exchange rate as determined and published by the Federal Reserve Bank of New York as of 12:00 PM (New York time) on each day that NYSE Arca is open for regular trading.

The functional currency of the Trust is the Mexican Peso in accordance with Financial Accounting Standard (“FAS”) 52, Foreign Currency Translation. For financial statement reporting purposes, the U.S. Dollar is the reporting currency. As a result, the financial statements are translated from Mexican Pesos to USD. The Noon Buying Rate on the last day of the period is used for translation in the statements of financial condition. The average Noon Buying Rate for the period is used for translation in the statement of income and comprehensive income and the statement of cash flows. Any currency translation adjustment is included in comprehensive income.

C. Federal Income Taxes

The Trust is treated as a “grantor trust” for federal income tax purposes and, therefore, no provision for federal income taxes is required. Interest, gains and losses are “passed through” to the Shareholders.

Shareholders generally will be treated, for U.S. federal income tax purposes, as if they directly owned a pro-rata share of the assets held in the Trust. Shareholders also will be treated as if they directly received their respective pro-rata shares of the Trust’s income, if any, and as if they directly incurred their respective pro-rata shares of the Trust’s expenses. The acquisition of Shares by a U.S. Shareholder as part of a creation of a Basket will not be a taxable event to the Shareholder.

The Sponsor’s fee accrues daily and is payable monthly. For U.S. federal income tax purposes, an accrual-basis U.S. Shareholder generally will be required to take into account as an expense its allocable share of the USD-equivalent of the amount of the Sponsor’s fee that is accrued on each day, with such USD-equivalent being determined by the currency exchange rate that is in effect on the respective day. To the extent that the currency exchange rate on the date of payment of the accrued amount of the Sponsor’s fee differs from the currency exchange rate in effect on the day of accrual, the U.S. Shareholder will recognize a currency gain or loss for U.S. federal income tax purposes.

The Trust does not expect to generate taxable income except for gain (if any) upon the sale of Mexican Pesos and interest income. A non-U.S. Shareholder generally will not be subject to U.S. federal income tax with respect to gain recognized upon the sale or other disposition of Shares, or upon the sale of Mexican Pesos by the Trust, unless: (1) the non-U.S. Shareholder is an individual and is present in the United States for 183 days or more during the taxable year of the sale or other disposition, and the gain is treated as being from United States sources; or (2) the gain is effectively connected with the conduct by the non-U.S. Shareholder of a trade or business in the United States.

A non-U.S. Shareholder’s share of any interest income earned by the Trust generally will not be subject to U.S. federal income tax unless the Shares owned by such non-U.S. Shareholder are effectively connected with the conduct by the non-U.S. Shareholder of a trade or business in the United States.

7


D. Revenue Recognition

Interest on the primary deposit account accrues daily as earned and is received on a monthly basis.

E. Dividends

To the extent that the interest earned by the Trust exceeds the sum of the Sponsor’s fee for the prior month plus other Trust expenses, if any, the Trust will distribute, as a dividend, the excess interest earned in Mexican Pesos effective on the first business day of the subsequent month. The Trustee will direct that the excess Mexican Pesos be converted into USD at the prevailing market rate and the Trustee will distribute the USD as promptly as practicable to Shareholders on a pro rata basis (in accordance with the number of Shares that they own). For the month of April 2008, an income distribution of $0.49526 per share was paid on May 8, 2008.

3. Mexican Peso Deposits

Mexican Peso principal deposits are held in a Mexican Peso-denominated, interest-bearing demand account. For the six months ending April 30, 2008, there were Mexican Peso principal deposits of 350,000,000 and Mexican Peso principal redemptions of 200,000,000 resulting in an ending Mexican Peso principal balance of 400,000,000. This equates to 38,058,629 USD. For the year ending October 31, 2007, there were Mexican Peso principal deposits of 350,000,000 and Mexican Peso principal redemptions of 200,000,000 resulting in an ending Mexican Peso principal balance of 250,000,000. This equates to 23,365,359 USD. In addition, net interest associated with creation and redemption activity is held in a Mexican Peso-denominated non-interest-bearing account, and any balance is distributed in full as part of the monthly income distributions.

4. Redeemable Capital Shares

Shares are classified as “redeemable” for financial statement purposes, since they are subject to redemption. Shares are issued and redeemed continuously in Baskets in exchange for Mexican Pesos. Individual investors cannot purchase or redeem Shares in direct transactions with the Trust. Only Authorized Participants (as defined below) may place orders to create and redeem Baskets. An Authorized Participant is a DTC participant that is a registered broker-dealer or other institution eligible to settle securities transactions though the book-entry facilities of the DTC and which has entered into a contractual arrangement with the Trust and the Sponsor governing, among other matters, the creation and redemption process. Authorized Participants may redeem their Shares at any time in Baskets.

Due to expected continuing creations and redemptions of Baskets and the three-day period for settlement of each creation or redemption, the Trust reflects Shares created as a receivable. Shares redeemed are reflected as a liability on the trade date. Outstanding Shares are reflected at a redemption value, which is the NAV per Share at the period end date. Adjustments to redeemable capital shares at redemption value are recorded against retained earnings, or, in the absence of retained earnings, by charges against the cumulative translation adjustment.

Ending redemption balance    400,000   $ 38,256,356    250,000   $ 23,486,661  




The Trustee will calculate the Trust’s NAV each business day. To calculate the NAV, the Trustee will subtract the Sponsor’s accrued fee through the previous day from the Mexican Pesos held by the Trust (including all unpaid interest accrued through the preceding day) and calculate the value of the Mexican Pesos in USD based upon the Noon Buying Rate. If, on a particular evaluation day, the Noon Buying Rate has not been determined and announced by 2:00 PM (New York time), then the most recent Federal Reserve Bank of New York determination of the Noon Buying Rate shall be used to determine the NAV of the Trust unless the Trustee, in consultation with the Sponsor, determines that such price is inappropriate to use as the basis for such valuation. In the event that the Trustee and the Sponsor determine that the most recent Federal Reserve Bank of New York determination of the Noon Buying Rate is not an appropriate basis for valuation of the Trust’s Mexican Pesos, they shall determine an alternative basis for such evaluation to be employed by the Trustee. The Trustee also determines the NAV per Share, which equals the NAV of the Trust divided by the number of outstanding Shares. Shares deliverable under a purchase order are considered outstanding for purposes of determining NAV per Share; Shares deliverable under a redemption order are not considered outstanding for this purpose.

5. Sponsor’s Fee

The Sponsor’s fee accrues daily at an annual nominal rate of 0.40% of the Mexican Pesos in the Trust (including all unpaid interest but excluding unpaid fees, each as accrued through the immediately preceding day) and is paid monthly.

The Sponsor assumes and pays the following administrative and marketing expenses incurred by the Trust: the Trustee’s monthly fee, NYSE Arca listing fees, SEC registration fees, typical maintenance and transaction fees of the Depository, printing and mailing costs, audit fees and expenses, up to $100,000 per year in legal fees and expenses, and applicable license fees. The Sponsor has also paid the costs of the Trust’s organization and the initial sales of the Shares, which were approximately $232,000 when the Trust was formed.

In certain exceptional cases, the Trust will pay for some expenses in addition to the Sponsor’s fee. These exceptions include expenses not assumed by the Sponsor (i.e., expenses other than those identified in the preceding paragraph), taxes and governmental charges, expenses and costs of any extraordinary services performed by the Trustee or the Sponsor on behalf of the Trust or action taken by the Trustee or the Sponsor to protect the Trust or the interests of Shareholders, indemnification of the Sponsor under the Depositary Trust Agreement, and legal expenses in excess of $100,000 per year.

6. Related Parties

The Sponsor is a related party of the Trust. The Sponsor oversees the performance of the Trustee and the Trust’s principal service providers, including the preparation of financial statements, but does not exercise day-to-day oversight over the Trustee or the Trust’s service providers. The Sponsor has paid the costs of the Trust’s organization and the initial sales of the Shares, as described in Note 5.

7. Concentration Risk

All of the Trust’s assets are Mexican Pesos, which creates a concentration risk associated with fluctuations in the price of the Mexican Peso. Accordingly, a decline in the price of the Mexican Peso to USD exchange rate will have an adverse effect on the value of the Shares. Factors that may have the effect of causing a decline in the price of the Mexican Peso include national debt levels and trade deficits, domestic and foreign inflation rates, domestic and foreign interest rates, investment and trading activities of institutions and global or regional political, economic or financial events and situations. Substantial sales of Mexican Pesos by the official sector (central banks, other governmental agencies and related institutions that buy, sell and hold Mexican Pesos as part of their reserve assets) could adversely affect an investment in the Shares.

8. Commitments and Contingencies

Under the Trust’s organizational documents, the Sponsor is indemnified against any liability or expense it incurs without negligence, bad faith or willful misconduct on its part. The Trust’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Trust that have not yet occurred.

Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Cautionary Statement Regarding Forward-Looking Information and Risk Factors

This report contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These statements are predictions and actual events or results may differ materially from those expressed in our forward-looking statements. Risks and uncertainties may cause our actual results to differ materially from those expressed in our forward-looking statements.

The value of the Shares relates directly to the value of the Mexican Pesos held by the Trust and fluctuations in the price of the Mexican Peso could materially adversely affect an investment in the Shares. Readers are urged to review the “Risk Factors” section contained in the Prospectus for a description of other risks and uncertainties that may affect an investment in the Shares.

The discussion and analysis which follows may contain statements that relate to future events or future performance. In some cases, such forward-looking statements can be identified by terminology such as “anticipate,” “expect,” “intend,” “plan,” “believe,” “seek,” “outlook” and “estimate” as well as similar words and phrases that signify forward-looking statements. Neither Rydex Specialized Products d/b/a Rydex Investments (the “Sponsor”) nor any other person assumes responsibility for the accuracy or completeness of forward-looking statements. Further, these forward-looking statements are made as of the date of this report, and will not be revised or updated to reflect actual results or changes in the Sponsor’s expectations or predictions.

Trust Overview

CurrencySharesSM Mexican Peso Trust (the “Trust”) is a grantor trust that was formed on June 8, 2006. The Trust issues shares (the “Shares”) in blocks of 50,000 each (a “Basket”) in exchange for deposits of Mexican Pesos and distributes Mexican Pesos in connection with the redemption of Baskets.

The Trust is a passive investment vehicle. The Trust does not have any officers, directors or employees. The investment objective of the Trust is for the Shares to reflect the price of the Mexican Peso plus accrued interest, less the expenses of the Trust’s operations. The Trust does not engage in any activities designed to obtain profit from, or ameliorate losses caused by, changes in the price of the Mexican Peso.

The Shares, which began trading on June 26, 2006, trade under the ticker symbol “FXM” on NYSE Arca. Investing in the Shares does not insulate the investor from certain risks, including price volatility.

Definition and Calculation of Net Asset Value

The net asset value (“NAV”) of the Trust is the aggregate value, expressed in U.S. Dollars (“USD”), of the Trust’s assets. To calculate the NAV, The Bank of New York (the “Trustee”) adds to the amount of Mexican Pesos in the Trust at the end of the preceding business day accrued but unpaid interest, Mexican Pesos receivable under pending purchase orders and the value of other Trust assets, and subtracts the accrued but unpaid Sponsor’s fee, Mexican Pesos payable under pending redemption orders and other Trust expenses and liabilities, if any.

11


The NAV is expressed in USD based on the Noon Buying Rate as determined by the Federal Reserve Bank of New York. If, on a particular evaluation day, the Noon Buying Rate has not been determined and announced by 2:00 PM (New York time), then the most recent Federal Reserve Bank of New York determination of the Noon Buying Rate shall be used to determine the NAV of the Trust unless the Trustee, in consultation with the Sponsor, determines that such price is inappropriate to use as the basis for such valuation. The Trustee also determines the NAV per Share, which equals the NAV of the Trust divided by the number of outstanding Shares.

The Sponsor publishes the NAV and NAV per Share on each day that NYSE Arca is open for regular trading on the Trust’s website, www.currencyshares.com .

The following chart illustrates the movement in the price of the Shares based on NAV per Share and the “bid” and “ask” midpoint offered on the NYSE (prior to October 30, 2007) and NYSE Arca (on or after October 30, 2007) as of the Noon Buying Rate versus the corresponding Mexican Peso (expressed as a multiple of 1,000 Mexican Pesos – Noon Buying Rate x 1,000):

Liquidity

The Sponsor is not aware of any trends, demands, conditions or events that are reasonably likely to result in material changes to the Trust’s liquidity needs. The Trust’s Depository, JPMorgan Chase, London Branch, maintains two deposit accounts for the Trust, a primary deposit account that earns interest and a secondary deposit account that does not earn interest. Interest on the primary deposit account accrues daily and is paid monthly. The interest rate paid as of April 30, 2008 was an annual nominal rate of 5.84%. The following chart provides the daily rate paid by the Depository since the Trust’s Shares began trading:

12


In exchange for a fee, the Sponsor bears most of the expense incurred by the Trust. As a result, the only ordinary expense of the Trust during the period covered by this report was the Sponsor’s fee. Each month the Depository deposits into the secondary deposit account accrued but unpaid interest and the Trustee, withdraws Mexican Pesos from the secondary deposit account to pay the accrued Sponsor’s fee for the previous month plus other Trust expenses, if any. When the interest deposited exceeds the sum of the Sponsor’s fee for the prior month plus other Trust expenses, if any, the Trustee converts the excess into USD at a prevailing market rate and distributes the USD as promptly as practicable to Shareholders on a pro rata basis (in accordance with the number of Shares that they own). Distributions paid during the current reporting period follow (annualized yield reflects the estimated annual yield an investor would receive if a monthly distribution stayed the same for the entire year going forward, and is calculated by annualizing the monthly distribution and dividing by the Trust NAV for the dates listed below):



FXM Distribution History - Current Period
 

Date Value NAV Yield Annualized Yield
04/01/2008 $0.55788 $94.35 0.59% 6.98%
03/03/2008 $0.39139 $93.50 0.42% 5.28%
02/01/2008 $0.44849 $92.53 0.48% 5.72%

Critical Accounting Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the Sponsor’s management to make estimates and assumptions that affect the reported amounts of the assets and liabilities and disclosures of contingent liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the period covered by this report.

In addition to the description below, please refer to Note 2 to the consolidated financial statements for further discussion of our accounting policies.

The Trustee calculates the Trust’s NAV each business day. For NAV calculation purposes, Mexican Peso Deposits (cash) are translated at the Noon Buying Rate as determined and published by the Federal Reserve Bank of New York as of 12:00 PM (New York time) on each day that NYSE Arca open for regular trading.

The functional currency of the Trust is the Mexican Peso in accordance with Financial Accounting Standard 52, Foreign Currency Translation.

Results of Operations

The Trust was formed on June 8, 2006 and the Shares commenced trading on the NYSE on June 26, 2006. The primary listing of the Shares was transferred to NYSE Arca on October 30, 2007. As of October 31, 2006 the number of Mexican Peso owned by the Trust was 100,000,000 resulting in a redeemable capital share value of $9,335,391. As of October 31, 2007 the number of Mexican Peso owned by the Trust was 250,000,000 resulting in a redeemable capital share value of $23,486,661.

During the six months ending April 30, 2008, an additional 350,000 shares had been created in exchange for 350,000,000 Mexican Pesos and 200,000 shares were redeemed in exchange for 200,000,000 Mexican Pesos. As of April 30, 2008, the number of Mexican Pesos owned by the Trust was 400,000,000 resulting in a redeemable capital share value of $38,256,356.

Movements in the Price of the Mexican Peso

The investment objective of the Trust is for the Shares to reflect the price of the Mexican Peso plus accrued interest, less the expenses of the Trust’s operations. The Shares are intended to provide institutional and retail investors with a simple, cost-effective means of gaining investment benefits similar to those of holding Mexican Peso. Each outstanding Share represents a proportional interest in the Mexican Pesos held by the Trust. The following chart provides recent trends on the price of the Mexican Peso. The chart illustrates movements in the price of the Mexican Peso in USD and is based on the Noon Buying Rate as determined by the Federal Reserve Bank of New York.

Not applicable.

Item 4T. CONTROLS AND PROCEDURES

The Trust maintains disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) designed to ensure that material information relating to the Trust is recorded, processed and disclosed on a timely basis. The Trust’s disclosure controls and procedures are designed by or under the supervision of the Sponsor’s chief executive officer and chief financial officer who exercise oversight over the Trust as the Trust has no officers. The chief executive officer and chief financial officer of the Sponsor have evaluated the effectiveness of the Trust’s disclosure controls and procedures as of April 30, 2008. Based on that evaluation, the chief executive officer and chief financial officer of the Sponsor have concluded that the disclosure controls and procedures of the Trust were effective as of the end of the period covered by this report. There were no changes in the Trust’s internal control over financial reporting that occurred during the Trust’s last fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Trust’s internal control over financial reporting.
