CurrencyShares® Singapore Dollar Trust

Notes to Financial Statements

(Unaudited)



|1. | Organization and Description of the Trust
|-- | -----------------------------------------

The CurrencyShares® Singapore Dollar Trust (the Trust)
was formed under the laws of the State of New York on August 7, 2008. On August 8, 2008, Rydex Specialized Products LLC d/b/a Rydex Investments (the Sponsor) deposited 100 Singapore Dollars 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 Security Investors, LLC (also d/b/a Rydex Investments). The
Sponsor is responsible for, among other things, overseeing the performance of The Bank of New York Mellon (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 Singapore Dollar 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 Singapore Dollar. The Trusts assets primarily consist of Singapore Dollars on demand deposit in two deposit accounts maintained by the Depository: a primary deposit account which may earn interest and a secondary
deposit account which does not earn interest. The secondary deposit account is used to account for any interest that may be received and paid out on creations and redemptions of 50,000 Shares (Baskets). The secondary account is also used
to account for interest earned, if any, 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/A as filed on March 10, 2011.



|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, the reported amounts of revenue and expenses during the period and the evaluation of subsequent events through the issuance date of the financial statements. Actual results could differ
from those estimates.



|B. | Foreign Currency Translation
|-- | ----------------------------

The Trustee
will calculate the Trusts net asset value (NAV) each business day, as described in Note 4. For NAV calculation purposes, Singapore Dollar deposits (cash) are translated at the Closing Spot Rate, which is the U.S. Dollar
(USD)/South African Rand exchange rate as determined by WM/Reuters at 4:00 PM (London time) on each day that NYSE Arca is open for regular trading.

The functional currency of the Trust is the Singapore Dollar in accordance with generally accepted accounting standards. For financial statement reporting purposes, the U.S. Dollar is the reporting
currency. As a result, the financial records of the Trust are translated from Singapore Dollar to USD. The Closing Spot Rate on the last day of the period is used for translation in the statements of financial condition. The average Closing Spot
Rate for the period is used for translation in the statements of income and comprehensive income and the statements 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 portion of the Trusts income, if any, and as if they directly incurred their respective pro-rata portion 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 portion 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 interest income (if any) and gain (if any) upon the sale of Singapore Dollar. 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 Singapore Dollar 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 portion 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.



|D. | Revenue Recognition
|-- | -------------------

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



|E. | Dividends
|-- | ---------

To the extent that the
interest earned by the Trust, if any, 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 (herein referred to as dividends or distributions), the excess interest
earned in Singapore Dollar effective on the first business day of the subsequent month. The Trustee will direct that the excess Singapore Dollar be converted into USD at a 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).



|3. | Singapore Dollar Deposits
|-- | -------------------------

Singapore
Dollar principal deposits are held in a Singapore Dollar-denominated, interest-bearing demand account. For the six months ended April 30, 2011, there were no principal deposits and no principal redemptions resulting in an ending Singapore
Dollar balance of 100. This equates to 82 USD. For the year ended October 31, 2010, there were no principal deposits and no principal redemptions resulting in an ending Singapore Dollar balance of 100. This equates to 77 USD.



|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 Singapore Dollar. 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 participant of the Depository Trust Company (DTC) that is a
registered broker-dealer or other institution eligible to settle securities transactions through the book-entry facilities of 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.

##### Table of Contents

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.

Activity in redeemable capital Shares is as follows:

Sponsors accrued fee through the previous day from the Singapore Dollar held by the Trust (including all unpaid interest accrued through the preceding day) and calculate the value of the Singapore Dollar in USD based upon the Closing Spot
Rate. If, on a particular evaluation day, the Closing Spot Rate has not been determined and announced by 6:00 PM (London time), then the most recent Closing Spot Rate will 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 the valuation. If the Trustee and the Sponsor determine that the most recent Closing Spot Rate is not an appropriate basis for valuation of the Trusts
Singapore Dollar, they will determine an alternative basis for the valuation. 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 will accrue daily at an annual nominal rate of 0.40% of the Singapore Dollar in the Trust (including all unpaid interest but excluding unpaid fees, each as accrued through the immediately preceding day) and will be 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.

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.



|7. | Concentration Risk
|-- | ------------------

All of the
Trusts assets are Singapore Dollars, which creates a concentration risk associated with fluctuations in the price of the Singapore Dollar. Accordingly, a decline in the Singapore Dollar 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 Singapore Dollar 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 Singapore Dollars by the official sector (central banks, other governmental agencies and related institutions
that buy, sell and hold Singapore Dollars as part of their reserve assets) could adversely affect an investment in the Shares.

All of the
Trusts Singapore Dollars are held by the Depository. Accordingly, a risk associated with the concentration of the Trusts assets in accounts held by a single financial institution exists and increases the potential for loss by the
Trust and the Shareholders in the event that the Depository becomes insolvent.



|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.

Trust Overview

The CurrencyShares® Singapore Dollar Trust (the Trust)
is a grantor trust that was formed on August 7, 2008. The Trust issues shares (the Shares) in blocks of 50,000 (a Basket) in exchange for deposits of Singapore Dollars and distributes Singapore Dollars 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 Singapore Dollar plus accrued interest, if any, 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 Singapore Dollar.

Definition of Net Asset Value

The Trustee will calculate, and the Sponsor will publish, the Trusts Net Asset Value (NAV) each business day. To calculate the NAV, the
Trustee will add to the amount of Singapore Dollars in the Trust at the end of the preceding day accrued but unpaid interest, if any, Singapore Dollars receivable under pending purchase orders and the value of other Trust assets, and subtract the
accrued but unpaid Sponsors fee, Singapore Dollars payable under pending redemption orders and other Trust expenses and liabilities, if any. The NAV will be expressed in U.S. Dollars (USD) based on the Closing Spot
Rate, which is the USD/ Singapore Dollar exchange rate as determined by WM/Reuters as of 4:00 PM (London time) on each day that NYSE Arca is open for regular trading. If, on a particular evaluation day, the Closing Spot Rate has not been
determined and announced by 6:00 PM (London time), then the most recent Closing Spot Rate will 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 the valuation.

The Trustee will also determine the NAV per Share, which equals the NAV of the Trust divided by the number of
outstanding Shares. The NAV of the Trust and NAV per Share will be published by the Sponsor on each day that NYSE Arca is open for regular trading and will be posted on the Trusts website, www.currencyshares.com.

Movements in the Price of Singapore Dollar

The investment objective of the Trust is for the Shares to reflect the price in USD of the Singapore Dollar 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 Singapore Dollars. Each outstanding Share represents a proportional interest in the Singapore Dollars held
by the Trust. The following chart illustrates recent movements in the price of Singapore Dollars in USD as reported by the Bloomberg Professional service.

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 did not have any Authorized Participant creation activity during the fiscal quarter ended April 30, 2011. The balance reflected in the financial statements is seed capital from the Sponsor.

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.

|Item 3. | Quantitative and Qualitative Disclosures about Market Risk
|------- | ----------------------------------------------------------

Except as described above with respect to the USD/Singapore Dollar exchange rate and the nominal annual interest rate to be paid by the Depository on Singapore Dollars held by the Trust, the Trust is not
subject to market risk. The Trust does not hold securities and does not invest in derivative instruments.



|Item 4. | 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, 2011. 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.
