1.
Organization





MLM
IndexTM Fund (the “Trust”) was formed under the Business Trust Statute of the
State of Delaware as a business trust in December 1997 and commenced operations
on January 4, 1999. The Trust was organized for the primary purpose of seeking
capital appreciation through the speculative trading of a diversified portfolio
of futures contracts using the MLM IndexTM Trading Program, which is based upon
the MLM IndexTM (the “Index”). The Index is a benchmark of the hypothetical
returns available to a futures investor. The Index is comprised of a diverse
portfolio of futures markets, including both financial and tangible
markets.





Mount
Lucas Management Corporation (the “Manager”) is the investment manager of the
Trust and is responsible for the allocation of the Trust’s interest among a mix
of trading strategies. The Manager is a registered investment advisor under the
Investment Advisers Act of 1940, is registered as a commodity pool operator and
a commodity-trading advisor with the Commodity Futures Trading Commission and is
a member of the National Futures Association.

Summary of Significant Accounting Policies





Basis
of Presentation





The
accompanying financial statements have been prepared in conformity with
accounting principles generally accepted in the United States of
America.  The following is a summary of the significant accounting and
reporting policies used in preparing the financial statements.  These
financial statements should be read in conjunction with the audited financial
statements and accompanying notes included in the Trust’s Annual Report on Form
10-K for the year ended December 31, 2007.





Use
of Estimates





The
preparation of the accompanying 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 assets and liabilities and disclosure of contingent assets and
liabilities at the date of the financial statements and the reported amounts of
revenues and expenses during the reporting period.  Actual results
could differ from those estimates.





Cash
and Cash Equivalents





Cash
equivalents consist of highly liquid financial instruments with maturities of
three months or less.





Due
from Brokers





The
Trust’s trading activities utilize one broker located in the United States. Due
from broker represents cash balances held, unrealized profit or loss on futures
contracts, and amounts receivable or payable for transactions not settled at
March 31, 2008 and December 31, 2007.





Fair
Value Measurements





The Trust
adopted the provisions of SFAS 157 effective as of January 1, 2008. SFAS 157
defines fair value, establishes a framework for measuring fair value,
establishes a fair value hierarchy based on the quality of inputs used to
measure fair value and enhances disclosure requirements for fair value
measurements. In addition, SFAS 157 requires an issuer to incorporate changes in
its own credit spreads when determining the fair value of its
liabilities.

Summary of Significant Accounting Policies (continued)





Fair
Value Measurements (continued)





In
accordance with SFAS 157, the Trust has categorized its financial instruments,
based on the priority of the inputs to the valuation technique, into a
three-level fair value hierarchy. The fair value hierarchy gives the highest
priority to quoted prices in active markets for identical assets or liabilities
(Level 1) and the lowest priority to unobservable inputs (Level 3). If the
inputs used to measure the financial instruments fall within different levels of
the hierarchy, the categorization is based on the lowest level input that is
significant to the fair value measurement of the instrument.





Financial
assets and liabilities recorded on the statement of assets and liabilities are
categorized based on the inputs to the valuation techniques as
follows:





Level
1:





Financial
assets and liabilities whose values are based on unadjusted quoted prices for
identical assets or liabilities in an active market (examples include active
exchange-traded equity securities, listed derivatives, most U.S. government and
agency securities, and certain other sovereign government
obligations).





Level
2:





Financial
assets and liabilities whose values are based on the following:


a)
            Quoted
      prices for similar assets or liabilities in active markets (for example,
      restricted stock);


b)
            Quoted
      prices for identical or similar assets or liabilities in non-active
      markets (examples include corporate and municipal bonds, which trade
      infrequently);


c)
            Pricing
      models whose inputs are observable for substantially the full term of the
      asset or liability (examples include most over-the-counter derivatives,
      including interest rate and currency swaps);
and


d)
            Pricing
      models whose inputs are derived principally from or corroborated by
      observable market data through correlation or other means for
      substantially the full term of the asset or liability (for example,
      certain mortgage loans).





Level
3:





Financial
assets and liabilities whose values are based on prices or valuation techniques
that require inputs that are both unobservable and significant to the overall
fair value measurement. These inputs reflect management's own assumptions about
the assumptions a market participant would use in pricing the asset or liability
(examples include private equity investments, certain commercial mortgage whole
loans and long-dated or complex derivatives, including certain foreign exchange
options and long-dated options on gas and power).





As
required by SFAS 157, financial assets and liabilities are classified in their
entirety based on the lowest level of input that is significant to the fair
value measurement. As of March 31, 2008 all of the derivative instruments held
by the Trust are fair valued based on quoted prices in active markets (Level
1).





The
Trust’s trading positions are valued at market value and cash equivalents are
carried at their net asset value per share including accrued interest, as
applicable. All positions including the net unrealized appreciation or
depreciation are included in amounts due from broker. Market value is
principally based on listed market prices or broker or dealer price quotations.
The resulting change in unrealized profit or loss is reflected in net change in
unrealized appreciation (depreciation) on investments on the statements of
operations.

Investment
Transactions and Investment Income





All
securities transactions are recorded on a trade-date basis. Realized gain and
loss are recorded using specific identification method. Interest income is
recorded using the accrual basis of accounting.





Income
Taxes





Both the
Unleveraged Series and the Leveraged Series are classified for federal income
tax purposes as separate partnerships. Investors in each Series will reflect
their proportionate share of realized profit or loss on their separate tax
returns. Accordingly, no provisions for income taxes are required for the
Trust.

4.
Investors’ Interest





The Trust
is comprised of two series: the Unleveraged Series, which attempts to replicate
the Index without leverage, and the Leveraged Series (collectively, the
“Series”), which attempts to replicate the Index at three times
leverage.  Prior to December 2004, each Series had five classes of
shares: Class A, Class A-1, Class B, Class B-1 and Class C. On December 1, 2004,
Class D shares were offered in each Series. On December 31, 2004, the Manager
elected to close Class A-1 and Class B-1. Class A, Class B, Class C and Class D
shares are sold by authorized selling agents appointed by the Manager to
accredited investors at a price equal to each Class’s net asset value. Shares
may be redeemed at net asset value as of the last day of any month upon at least
ten business days’ written notice to the Manager.





The
Manager allocates profits and losses among the investors of a Series based on
the balance in each investor’s capital account.





The
Manager paid all of the expenses associated with the organization of the Trust
and the offered shares. As a result, each shareholder of Class A and Class B
shares pays the Manager an organizational fee in the amount of 0.5% of their
aggregate investment, net of any selling commission. Class A and Class B
shareholders are not charged an organizational fee once they have contributed a
total of $1,000,000 or more. Class C and Class D shareholders are not charged an
organizational fee.





The Class
A and Class C shares of the Unleveraged and Leveraged Series are subject to a
sales commission of 0% to 4% of the subscription amount, payable to the selling
agent from the investor’s investment for each series. The amount of the sales
commission will be determined by the selling agent.

Derivative Financial Instruments





Derivatives
are subject to various risks similar to non-derivative financial instruments
including market, credit, liquidity and operational risk. The risks of
derivatives should not be viewed in isolation but rather should be considered on
an aggregate basis along with the Trust’s other trading-related
activities.





The Trust
purchases and sells futures in financial instruments and
commodities.  The Trust records its derivative activities on a
mark-to-market basis with realized and unrealized gains (losses) recognized
currently in the statements of operations and in due from brokers on the
statements of financial condition.





The
following table reflects the fair value of the Trust’s derivative financial
instruments:

Item
      2.
            Management's
      Discussion and Analysis of Financial Condition and Results of
      Operations.





General





The Trust
is a business trust organized under the laws of Delaware.  The Trust
engages primarily in the speculative trading of a diversified portfolio of
futures contracts using the MLM IndexTM Trading Program (the “Trading
Program”).  Generally speaking, futures contracts are standardized
contracts made on or through a commodity exchange and provide for future
delivery of commodities such as precious metals, foreign currencies or financial
instruments.  Certain contracts can be settled only on a cash basis
such as stock index futures contracts and Eurodollar futures contracts
..  The Trust's objective is the appreciation of its assets through
speculative trading.  The Trust began trading on January 4,
1999.





Mount
Lucas Management Corporation (the “Manager”), a Delaware corporation, acts as
the manager and trading advisor of the Trust.  The Manager was formed
in 1986 to act as an investment manager.  As of March 31, 2008, the
Manager had approximately $1.7 billion of assets under
advisement.  The Manager is a registered investment adviser under the
Investment Advisers Act of 1940 and is a registered commodity trading advisor
and commodity pool operator with the Commodity Futures Trading Commission (the
"CFTC") and a member of the National Futures Association (the
"NFA").  The Manager does and may in the future operate other
investment vehicles.





The Trust
and the Manager maintain their principal business office at 47 Hulfish Street,
Suite 510, Princeton, New Jersey 08542 and their telephone number is (609)
924-8868.





The
purpose of the Trust is to replicate the results of the MLM IndexTM, an index
designed to measure the risk premium available to futures
traders.  Designed as such, the results of the Trust depend on two
factors, the results of the MLM IndexTM itself, and the Manager's ability to
replicate that Index.  It is important to note that the Manager also
calculates the results of the MLM IndexTM.  Thus, their role is twofold
- to calculate the results of the MLM IndexTM, and to replicate the results of
the MLM IndexTM for the Trust.  Any changes made to the composition of
the MLM IndexTM by the MLM IndexTM Committee of the Manager will affect the
trading of the Trust, since the objective of the Trust is to replicate the MLM
IndexTM as published.





Results
of the MLM IndexTM





The MLM
IndexTM is calculated from the prices of 22 generally liquid futures
contracts.  These markets are traded on domestic and foreign
exchanges.  For each market, the MLM IndexTM generally uses the price
of 4 different delivery months each year.  For example, in the
Japanese Yen futures market, the MLM IndexTM uses the March, June, September and
December delivery months.  On the day before trading day, the MLM
IndexTM determines whether to hold a long or short position in each constituent
contract based on the calculation methodology of the MLM IndexTM.  Once
established, that position is held for the subsequent period, at which time it
is re-evaluated.  The monthly results of each constituent market are
then used to calculate the MLM IndexTM return. The objective of the Trust is to
replicate this monthly return.





The
volatility of the constituent markets in the MLM IndexTM can affect the results
of the Trust.  The influences on this volatility are varied and
unpredictable.  However, since the objective of the Trust is to
replicate the MLM IndexTM, the Manager takes no unusual action to mitigate this
volatility.  The role of the Manager is to buy or sell the appropriate
number of futures contracts in each constituent market such that the aggregate
return of those positions replicates as closely as possible the results of the
MLM IndexTM.





16
 Index





In order
to accomplish this objective, the Manager must calculate the number of contracts
based on both the assets in the Trust and the distribution of the assets between
the Unleveraged and Leveraged Series of the Trust. Since the MLM IndexTM
rebalances positions each month, at that time the Manager must ascertain the
asset level and execute orders to achieve the desired
allocations.  This is achieved by adding the performance results of
the Trust for the month to the assets at the beginning of the month, and adding
additions of capital from new subscriptions and subtracting redemptions in order
to determine the asset level at the end of the period.





Summary
of Critical Accounting Policies





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 amounts reported in the financial
statements and accompanying notes.  Management believes that the
estimates utilized in preparing the financial statements are reasonable and
prudent; however, actual results could differ from those
estimates.  The Trust's significant accounting policies are described
in detail in Note 2 of the Notes to Unaudited Interim Financial
Statements.





The Trust
records all investments at market value in its financial statements, with
changes in market value reported as a component of “realized and unrealized gain
(loss)” on investments in the Statements of Operations. Generally, market values
are based on market prices; however, in certain circumstances, significant
judgments and estimates by the Manager are involved in determining fair value in
the absence of an active market closing price.





FASB
Statement 157 defines fair value, establishes a framework for measuring fair
value in generally accepted accounting principles (GAAP), and expands
disclosures about fair value measurements.  Statement 157 is effective
for financial statements issued for fiscal years beginning after November 15,
2007, and for the interim periods that fall within those fiscal
years.





Financial
Condition





To
replicate the results of the MLM IndexTM, the Trust must effect trades on
domestic or foreign futures exchanges.  From the beginning of
operations until October 2005, the Trust used Refco, LLC (“Refco”) as its
futures commission merchant.  In October 2005 the Trust moved all of
its brokerage accounts to Citigroup Global Markets (“CGM”).  The
Manager deposits a percentage of the assets of the Trust in two separate
accounts at CGM, one for the Unleveraged Series and one for the Leveraged
Series.  The amount deposited is determined by the margin requirement
established by the exchanges to hold the positions in the Trust.  The
margin requirements vary, but are generally about 2% of assets for the
Unleveraged Series and 6% of assets for the Leveraged Series.





The
balance of the assets of the Trust is held in two separate custodial accounts at
State Street Bank (the “Bank”).  The Trust has contracted with Credit
Suisse Asset Management (CSAM) to manage the money in these accounts so as to
maximize the interest income, which accrues to the Trust, while maintaining
strict credit controls as determined by the Commodities Exchange
Act.  When CGM requires additional assets to maintain the positions
for the Trust, the Bank makes a wire transfer to CGM.  If CGM has
surplus assets in the accounts, CGM makes a wire transfer to the accounts at the
Bank.





The Trust owns no capital assets and
does not borrow money.  Since the objective of the Trust is to
replicate the results of the MLM IndexTM, its entire asset base participates in
the speculative trading of futures contracts.  As such, all assets of
the Trust are at risk.  The level of assets will be determined by the
results of the Trust, the effect of capital additions and the redemption of
Trust interests.  These variables are impossible to predict with any
certainty.





17
 Index





The Trust
purchases and sells futures in financial instruments and
commodities.  The Trust records its derivative activities on a
mark-to-market basis with realized and unrealized gains (losses) recognized
currently in the statements of operations and in due from brokers on the
statements of financial condition.   FASB Statement 157 defines
fair value, establishes a framework for measuring fair value in generally
accepted accounting principles (GAAP), and expands disclosures about fair value
measurements.  Statement 157 is effective for financial statements
issued for fiscal years beginning after November 15, 2007, and for the interim
periods that fall within those fiscal years.  As of March 31, 2008 and
December 31, 2007, all of the derivative instruments held by the Trust are fair
valued based on quoted prices in active markets (Level 1).





Liquidity





The
majority of the Trust's assets are held in liquid short term interest rate
instruments.  The Trust takes substantial exposure in futures markets,
which require relatively small deposits, called margin, to hold the positions.
In general, the Trust will have the minimum amount on deposit with brokers as
margin, with the balance held in custodial accounts with the Bank.





Upon 10
days written notice to the Manager, a holder of interests in the Trust may
liquidate their holding at the end of any month at the net asset value of the
interests at that month end.  While the Manager will generally honor
all requests for redemption if presented in proper form, the Manager may
temporarily suspend any redemption if the effect of such redemption, either
alone or in conjunction with other redemptions, would impair the relevant
Series' ability to operate.  Further, the right to obtain redemption
is contingent upon the relevant Series having assets sufficient to discharge its
liabilities on the date of redemption.  For example, under certain
circumstances, the Manager may find it advisable to establish a reserve for
contingent liabilities.  In such event, the amount receivable by a
redeeming holder of interests will be reduced by his proportionate share of the
reserve.  There is no secondary market for interests in the Trust, and
none is anticipated to develop.  There are restrictions on transfer of
interests contained within the Trust Agreement.





Although
the Trust trades in futures contracts which are in general liquid, the exchanges
impose daily trading limits, which act to suspend trading when a particular
market or contract trades up or down to a pre-determined price
level.  Should this happen, and the Trust was attempting to execute
trades in that situation, the Trust may not be able to accurately replicate the
results of the MLM IndexTM.  These rules have not had a material impact
on the operation of the Trust to date but future impact is impossible to
predict.





Market
and Credit Risks





The
nature of the Trust is such that it undertakes substantial market risk in
following its mandate to replicate the MLM IndexTM.  Although the
Manager monitors the intraday and daily valuation of the portfolio, no
extraordinary measures are taken to reduce market risk.  Specifically,
the Manager maintains positions required to match, as closely as possible, the
return of the MLM Index.  There could be certain circumstances where
the Manager might be called upon to make a change to this policy, such as the
closing of an exchange or some other emergency situation.  In such
case, the Manager would use its best efforts to respond to such circumstances
with the interests of the investors in mind.





The MLM
IndexTM is designed to capture returns from sustained trends in the constituent
futures markets.  When these trends exist in a market or sector, the
MLM IndexTM tends to exhibit positive performance in that market or
sector.  Conversely, if a market or sector is trendless and volatile,
the performance for the market or sector is likely to be
negative.  The lack of any significant trend is generally an
indication of poor results.





The MLM
IndexTM is not designed to predict which market will exhibit positive performance
in any given year.  The Manager does not select the constituent
markets based on expectations of future performance.  The MLM IndexTM
is designed to represent participation in a diverse basket of future contracts
using a trend-following algorithm.  The MLM IndexTM is a diversified
Index producing different levels of return in the various sectors from
year-to-year.





18
 Index





The Trust
incurs various kinds of credit risk in its operations.  In order to
facilitate the trading of the Trust, assets must be placed with both Futures
Commission Merchants and Broker/Dealers.  Management of the Trust
deals only with established registered firms in both capacities, and monitors
their financial condition on an ongoing basis. In addition, if the Trust were to
enter into over-the-counter (“OTC”) transactions, additional counterparty risk
would be incurred.  There were no OTC transactions for the three
months ending March 31, 2008.





Results
of Operations





At March
31, 2008, the Trust had assets of $127,816,354 and liabilities of $1,443,877
compared with assets of $120,016,936 and liabilities of $2,631,205 at December
31, 2007.  Changes in the net assets of the Trust are the result of
subscriptions and redemptions to the Trust, and the net income (loss) from
operations, including the results from futures trading, interest income, and
fees and expenses.  For the three-month period ended March 31, 2008,
subscriptions to the Trust totaled $5,824,157 and redemptions totaled
$4,688,566.  During the three-month period ended March 31, 2008, the
Trust had a net income of $7,851,155 compared with a net loss of $5,051,306 for
the same period in 2007.  Some expenses of the Trust are based on a
percentage of net assets, and therefore increase or decrease as the net assets
of the Trust increase or decrease.





The
Trust’s net income is directly related to the performance of the MLM IndexTM,
which the Trust is designed to replicate.  For the three months ended
March 31, 2008, MLM IndexTM performance was a positive
3.78%.  Performance was a negative (1.68%) for the same period ended
March 31, 2007.  The Trust’s performance may be negative in years when
the MLM IndexTM is positive due to the timing of subscriptions and redemptions,
the fees charged and/or the allocation of assets between the Unleveraged and
Leveraged Series of the Trust.  Since inception of the Trust, the
correlation of monthly results between the Unleveraged Series of the Trust and
the MLM IndexTM adjusted for fees is 0.99.  The correlation between the
Leveraged Series of the Trust and the MLM IndexTM adjusted for leverage and fees
is 0.99.





The
components of the return of the MLM IndexTM are the capital gains earned from the
changes in futures market prices and the interest income earned on cash balances
less expenses incurred.  The mechanics and rules of futures markets
allow the Trust to earn interest on approximately 100% of the assets in the
Trust.  The interest income takes two forms:  that paid
directly from the Trust's futures broker on margin deposits held by it, and
excess cash.





Item3.
            Quantitative
      and Qualitative Disclosures About Market
Risk.





The
following is a discussion of the quantification of market risk for the
Trust.  Such calculations are often referred to as Value-at-Risk
(“VAR”).  The method used here may or may not differ from other
methods used for VAR calculations by other firms.  There is no one
generally accepted method of VAR calculation and this method may not be
comparable to methods used by others.





The
market risk, or VAR of the Trust, is directly related to the composition of the
MLM IndexTM.  Each month, the position of the MLM IndexTM can be either
long or short based on a 252 business day moving average rule.  Since
positions can be offset inside of sectors (one contract long in a particular
commodity and one contract short in a related commodity), specific sector risk
is less relevant than the historical risk of the MLM IndexTM as a
whole.  Since the objective of the Trust is to replicate the MLM
IndexTM, it is reasonable to use the historic values of that Index to estimate
market risk.





19
 Index





The VAR
of the Trust is calculated as follows:





1.
            The
      Manager calculates the standard deviation of the historical returns of the
      MLM IndexTM over two time periods, using daily returns over the preceding 1
      year ending at the date of this report, and using monthly returns over the
      preceding 10 years.  Those results for the period ended March
      31, 2008 are 0.26% and 1.80% respectively.  It is important to
      note that this calculation is made on the historical data of the MLM
      IndexTM.  It is not based on the actual trading of the Trust and,
      accordingly, does not include any operational risk.  The
      standard deviation is used to measure the dispersion of the returns of the
      MLM IndexTM over time.





2.
            For
      the purposes of VAR, an attempt is made to estimate the size of a loss
      that may occur with some small probability.  VAR does not
      estimate the possibility of a total loss, only the probability of a loss
      of some magnitude.  The calculation is complicated by the fact
      that the standard deviation of the distribution assumes a normal
      distribution, which may or may not be a good estimate of the actual
      distribution.  For the purposes of this estimate, the Manager
      has chosen to calculate the size of a daily and monthly loss that might
      occur with a probability of 1% (1 chance in 100).  To do this,
      the standard deviation is multiplied by 2.35 to the standard 99%
      confidence interval, and by 1.5 to adjust for the possibility of a
      non-normal distribution.  Using this methodology, for daily
      returns, this estimate is a loss of 0.92%.  For monthly returns,
      the estimate is a loss of 6.35%.





3.
            To
      ascertain a dollar loss amount for the Trust, the assets of the Trust as
      of March 31, 2008 are multiplied by the estimate of the risk calculated in
      step 2 above.  The risk estimate is based on the Unleveraged MLM
      IndexTM, so Trust assets must be adjusted for the distribution of assets
      among the Unleveraged and Leveraged Series of the Trust, with the
      leveraged assets having three times the risk of the Unleveraged
      assets.  Based on the asset levels as of March 31, 2008, the
      Manager estimates that the Trust could expect to lose approximately $2
      million in any given day and $13.7 million in any given
    month.





The
estimate above, though reasonable, should not be taken as an assurance that
losses in the Trust could not be greater than these amounts.  This is
simply a quantitative estimate based on the historical performance of the MLM
IndexTM.  A loss that occurs with a small probability may be
substantially greater than the loss indicated above.  Also, market
conditions could change dramatically from the conditions that prevailed over the
period used to calculate the estimate, thereby affecting the realized volatility
of the market.  Furthermore, other factors could affect trading, such
as the inability to execute orders in a particular market due to operational or
regulatory restrictions that may alter the pattern of the Trust’s
returns.  Specifically, the Manager advises other funds in addition to
the Trust.  In certain markets there is a limit to the size of a
position that one entity can control (speculative limits).  Since
positions cannot exceed speculative limits, the Manager may have to allocate
positions across accounts and funds, resulting in a less than complete
replication of the MLM IndexTM.  As outlined in the offering for the
Trust, it is best to remember that all the assets invested are at a risk of
loss.





Since the
calculation of the VAR does not look at the specific instrument risks, but
rather the results of the MLM IndexTM as a whole, risks related to actual
execution are not included in the calculation.  For example,
counter-party risks from OTC transactions are not and cannot be factored into
the calculation.





Additional
market risk may be attributed to the actual execution of the orders for the
Trust.  The Trust executes the majority of its orders on the last day
of each month.  As assets of the Trust grow, large orders may be
placed in periods of reduced liquidity.  Such orders may move the
markets in which they are executed, adversely affecting the performance of the
Trust.  The Manager makes every effort to execute all orders
efficiently, but general levels of liquidity are beyond its
control.  In certain circumstances, markets may move to the daily
trading limits imposed by the exchanges, and the Trust may be unable to execute
the necessary orders to replicate the MLM IndexTM, causing a divergence of
performance between the Trust and the MLM IndexTM, known as
“slippage”.

            Controls
      and Procedures.





The
President and the Chief Operating Officer of the Manager (collectively the
“Certifying Officers”) maintain a system of disclosure controls and procedures
that is designed to provide reasonable assurance that information, which is
required to be disclosed, is accumulated and communicated to management in a
timely manner.  The Certifying Officers have concluded that the
disclosure controls and procedures are effective at the “reasonable assurance”
level.  As of March 31, 2008, the Certifying Officers evaluated the
effectiveness of the design and operation of the disclosure controls and
procedures (as defined in Rule [13a-15(e)/15d-15(e)] under the Exchange
Act).  Furthermore, the Certifying Officers concluded that disclosure
controls and procedures in place were designed to ensure that information
required to be disclosed in reports that are filed or submitted under the
Exchange Act are (i) recorded, processed, summarized and reported on a timely
basis in accordance with Commission rules and regulations; and (ii) accumulated
and communicated to the Certifying Officers and other persons that perform
similar functions, if any, to allow them to make timely decisions regarding
required disclosure in periodic filings.  There have been no
significant changes in the Trust’s internal control over financial reporting in
the quarter ended March 31, 2008 that has materially affected or is reasonably
likely to materially affect the Trust’s internal control over financial
reporting.
