Notes Notes to Financial Statements (unaudited)

The accompanying unaudited financial statements, in the opinion of management, include all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of Man-AHL Diversified I L.P’s (a Delaware Limited Partnership) (the “Partnership”) financial condition at September 30, 2008 and the results of its operations for the three months ended September 30, 2008 and 2007 and nine months ended September 30, 2008 and 2007. These financial statements present the results of interim periods and do not include all the disclosures normally provided in annual financial statements. It is suggested that these financial statements be read in conjunction with the audited financial statements and notes included in the Partnership’s annual report and registration statement on Form 10 filed with the Securities and Exchange Commission on January 28, 2008 and amended March 26, 2008. The December 31, 2007 information has been derived from the audited financial statements as of December 31, 2007.

1.	ORGANIZATION OF THE PARTNERSHIP

Man-AHL Diversified I L.P. (a Delaware Limited Partnership) (the “Partnership”) was organized in September 1997 under the Delaware Revised Uniform Limited Partnership Act and commenced operations on April 3, 1998, for the purpose of engaging in the speculative trading of futures and forward contracts. The Partnership is a “feeder” fund in a “master-feeder” structure whereby the Partnership invests substantially all of its assets in Man-AHL Diversified Trading Company L.P. (the “Trading Company”). Man-AHL (USA) Corp., a Delaware corporation, was the general partner and trading advisor of the Partnership and the Trading Company until April 1, 2005, when it transferred its trading advisory business to its affiliate, Man-AHL (USA) Ltd. (the “Advisor”), a United Kingdom company, and its commodity pool operations to its affiliate, Man Investments (USA) Corp. (the “General Partner”), a Delaware corporation and a registered investment adviser under the Investment Advisers Act of 1940. Man Investments Holdings Limited, a United Kingdom holding company that is part of Man Group plc, a United Kingdom public limited company, is the sole shareholder of the Advisor, and Man Investments Holdings Inc., a Delaware corporation that is part of Man Group plc, is the sole shareholder of the General Partner.

Effective July 1, 2008, the Partnership issued a new share class, Class B. Class B was created solely for retirement plan investors. The fee structure is identical to Class A.

The Partnership’s interests are distributed through the Partnership or other selling agents, including Man Investments Inc. (“MII”), an affiliate of the Advisor and General Partner. MII is a registered broker-dealer and a member of the Financial Industry Regulatory Authority (FINRA).

On January 28, 2008, the Partnership filed a registration statement with the Securities and Exchange Commission to allow over 500 investors in the Partnership.

2.	SIGNIFICANT ACCOUNTING POLICIES

The Partnership prepares its financial statements 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.

Investment in Man-AHL Diversified Trading Company L.P. — The Partnership’s investment in the Trading Company is valued at fair value at the Partnership’s proportionate interest in the net assets of the Trading Company. Investment transactions are recorded on a trade date basis. The performance of the Partnership is directly affected by the performance of the Trading Company. Attached are the financial statements of the Trading Company, which are an integral part of these financial statements. Valuation of investments held by the Trading Company is discussed in the notes to the Trading Company’s financial statements.

The Partnership can redeem any or all of its limited partnership interests in the Trading Company at any month-end at the net asset value per unit of the Trading Company. At September 30, 2008 and 2007, the Partnership owned 17,371 and 7,621 Class A units, respectively, of the Trading Company. The Partnership also owned 2,077 Class B units at September 30, 2008. The Partnership’s aggregate ownership percentage of the Trading Company (both Class A and B units) at September 30, 2008 and 2007, was 39.83% and 21.97%, respectively.

Cash and Cash Equivalents — Cash and cash equivalents include cash and short-term interest bearing money market instruments with original maturities of 90 days or less, held with JPMorgan Chase, N.A.

Brokerage Commissions Expense — Brokerage commission expense on futures and forward contracts traded in the Trading Company is recognized on a half-turn basis in the period in which the contracts are opened or closed.

Income Taxes — Income taxes are not provided for by the Partnership because taxable income or loss of the Partnership is includable in the income tax returns of the individual partners.

Net Income (Loss) Per Unit — Net income (loss) per unit of Class A or Class B partnership interest is equal to the change in net asset value per unit of the respective classes, from the beginning of the period to the end of the period. Unit amounts are rounded to whole numbers for financial statement presentation.

Subscriptions Received in Advance — Subscriptions received in advance are comprised of cash received prior to the statement of financial condition date for which units were issued on the first day of the following month. Subscriptions received in advance do not participate in the earnings of the Partnership until the related units are issued.

Use of Estimates — The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the General Partner 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.

3.	LIMITED PARTNERSHIP AGREEMENT

The General Partner and each limited partner share in the profits and losses of the Partnership in proportion to the number of units or unit equivalents held by each partner. However, no limited partner is liable for obligations of the Partnership in excess of its capital subscription and net profits or losses, if any.

The Partnership’s units are continuously offered as of the first business day of each month at net asset value, as defined in the limited partnership agreement (the “Agreement”). Limited partners may redeem any or all of their units as of the end of any month at net asset value per unit on 10 days prior written notice to the General Partner. The Partnership will be dissolved on December 31, 2037, or upon the occurrence of certain events, as specified in the Agreement.

The General Partner is required to make and maintain a general partner investment in the Partnership in an aggregate amount equal to the lesser of 1.01 % of the net aggregate capital subscriptions of all partners, or $500,000.

Distributions (other than redemptions of units), if any, are made on a pro rata basis at the sole discretion of the General Partner.

Under the terms of the Agreement, the Partnership is liable for all costs associated with executing its business strategy. These costs include, but are not limited to expenses associated with the execution of the Partnership’s investments strategy, such as, brokerage commissions, management and incentive fees and other operating expenses, such as legal, audit, and tax return preparation fees.

EXPENSES

The Advisor earns a monthly management fee in an amount equal to 0.1667% (2% annually) of the Partnership’s month-end net asset value, as defined in the Agreement.

The Advisor also earns a monthly incentive fee equal to 20% of any Net New Appreciation, as defined in the Agreement, achieved by the Partnership. The incentive fee is retained by the Advisor even if subsequent losses are incurred; however, no subsequent incentive fees will be paid to the Advisor until any such trading losses are recouped by the Partnership.

The General Partner earns a monthly General Partner fee in an amount equal to 0.0833% (1% annually) of the Partnership’s month-end net asset value, as defined in the Agreement. The General Partner fee is included in management fees in the statements of operations.

The Partnership pays a monthly servicing fee to the placement agent in an amount equal to 0.1250% (1.5% annually) of the Partnership’s month-end net asset value, as defined in the supplement to the Agreement, dated July 15, 2008. MII serves as the placement agent for the Partnership.

5.	DERIVATIVE FINANCIAL INSTRUMENTS

The Partnership’s operating activities involve trading, indirectly through its investment in the Trading Company, in derivative financial instruments that involve varying degrees of market and credit risk. With respect to the Partnership’s investment in the Trading Company, the Partnership has limited liability, and, therefore, its maximum exposure to either market or credit loss is limited to the carrying value of its investment in the Trading Company, as set forth in the statements of financial condition.

The Trading Company utilizes MF Global, Inc. (“MFG”), formerly known as Man Financial Inc. (Man) and Credit Suisse to clear its futures business. The Trading Company utilizes Royal Bank of Scotland (“RBS”) to clear its forward business.

6.	FINANCIAL GUARANTEES

The Partnership enters into administrative and other professional service contracts that contain a variety of indemnifications. The Partnership’s maximum exposure under these arrangements is not known; however, the Partnership has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.

7.	FAIR VALUE MEASUREMENTS

Effective January 1, 2008, the Partnership has adopted the provisions of the Statement of Financial Accounting Standard No. 157 (“SFAS 157”), Fair Value Measurements. SFAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. The adoption of SFAS 157 had no impact on the net assets of the Partnership.

The Partnership segregates its investments into three levels based upon the inputs used to derive the fair value. “Level 1” investments use inputs from unadjusted quoted prices from active markets. “Level 2” investments reflect inputs other than quoted prices, but use observable market data. “Level 3” investments are valued using unobservable inputs. These unobservable inputs for “Level 3” investments reflect the Partnership’s assumption about the assumptions market participants would use in pricing the investments. As of September 30, 2008, all of the Partnership’s investments are “Level 3”. Net appreciation from the Partnership’s “Level 3” investments was $4,246,912, reflected in the statement of operations as income allocated from Man-AHL Diversified Trading Company L.P.

The following is a reconciliation of the investments in which significant unobservable inputs (Level 3) were used in determining fair value.

	Beginning Balance 31-Dec-07		Net Realized Gains From Investment In Trading Company			Net Unrealized Gains From Investment In Trading Company		Purchases		Sales			Net Transfers In and/or Out of Level 3		Ending Balance 30-Sep-08

Investment in Man-AHL Diversified Trading Company L.P.	$	59,555,095	$	3,591,954		$	654,958	$	112,845,991	$	(13,985,247	)		-	$	162,662,751


	Beginning Balance 30-Jun-08		Net Realized Losses From Investment In Trading Company			Net Unrealized Gains From Investment In Trading Company		Purchases		Sales			Net Transfers In and/or Out of Level 3		Ending Balance 30-Sep-08

Investment in Man-AHL Diversified Trading Company L.P.	$	120,904,873	$	(16,233,052	)	$	2,221,737	$	59,135,553	$	(3,376,360	)		-	$	162,662,751

Valuation of the above position are discussed in Note 2 of these financial statements.

8.	RECENT ACCOUNTING PRONOUNCEMENTS

Statement of Financial Accounting Standards No. 161 (“SFAS 161”), Disclosures about Derivative Instruments and Hedging Activities was issued on March 19, 2008. SFAS 161 expands the disclosures required by Statement of Financial Accounting Standards No. 133, Accounting for Derivatives and Hedging Activities about an entity’s derivative instruments and hedging activities. SFAS 161 is effective for fiscal years and interim periods beginning after November 15, 2008. The Partnership is currently evaluating the provisions of SFAS 161 and their impact on the Partnership’s financial statements.

Notes to Financial Statements (unaudited)

The accompanying unaudited financial statements, in the opinion of management, include all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of Man-AHL Diversified Trading Company L.P.’s (a Delaware Limited Partnership) (the “Partnership”) financial condition at September 30, 2008 and the results of its operations for the three months ended September 30, 2008 and 2007 and nine months ended September 30, 2008 and 2007. These financial statements present the results of interim periods and do not include all the disclosures normally provided in annual financial statements. It is suggested that these financial statements be read in conjunction with the audited financial statements and notes included in the Partnership’s annual report on Form 10 filed with the Securities and Exchange Commission for the year ended December 31, 2007. The December 31, 2007 information has been derived from the audited financial statements as of December 31, 2007.

1.	ORGANIZATION OF THE PARTNERSHIP

Man-AHL Diversified Trading Company L.P. (a Delaware Limited Partnership) (the “Partnership”) was organized in November 1997 under the Delaware Revised Uniform Limited Partnership Act and commenced operations on April 3, 1998, for the purpose of engaging in the speculative trading of futures and forward contracts. Man Investments (USA) Corp. (the “General Partner”), a Delaware corporation and a registered investment adviser under the Investment Advisers Act of 1940, serves as the Partnership’s general partner. The General Partner is a subsidiary of Man Group plc, a United Kingdom public limited company that is listed on the London Stock Exchange. The General Partner oversees the operations and management of the Partnership. The General Partner is registered with the Commodity Futures Trading Commission (“CFTC”) as a commodity pool operator and commodity trading adviser and is a member of the National Futures Association (“NFA”).

The Partnership was formed to serve as a trading vehicle for certain limited partnerships sponsored by the General Partner in a “master-feeder” structure. The limited partners, Man-AHL Diversified I L.P., Man-AHL Diversified II L.P., and Man-AHL Diversified L.P., are limited partnerships whose general partner is the General Partner.

Man-AHL (USA) Ltd. (the “Advisor”), a limited liability company incorporated in the United Kingdom, acts as trading advisor to the Partnership. The Advisor is an affiliate of the General Partner and a subsidiary of Man Group plc. The Advisor is registered with the CFTC as a commodity pool operator and commodity trading advisor, and is a member of the NFA, in addition to registration with the Financial Services Authority in the United Kingdom.

2.	SIGNIFICANT ACCOUNTING POLICIES

Due From Brokers — Due from brokers consists of balances due from MF Global, Inc. (“MFG”), formerly known as Man Financial Inc. (Man), Credit Suisse, and Royal Bank of Scotland (“RBS”). In general, the brokers pay the Partnership interest monthly, based on agreed upon rates, on the Partnership’s average daily balance.

MFG, Credit Suisse and RBS are registered with the CFTC as futures commission merchants and are members of the NFA.

Derivative Contracts — In the normal course of business, the Partnership enters into derivative contracts (derivatives) for trading purposes. Derivatives include futures and forward contracts. The Partnership records its derivative activities at fair value. Futures contracts which are traded on a national exchange are valued at the close price as of the valuation day, or if no sale occurred on such

day, at the close price on the most recent date on which a sale occurred. Forward contracts, which are not traded on a national exchange, are valued at fair value using current market quotations provided by brokers.

Income Recognition — Realized and unrealized trading gains and losses on futures and forward contracts, which represent the difference between cost and selling price or fair value, are recognized currently in the statements of operations. All trading activities are accounted for on a trade-date basis. Interest income is recorded on an accrual basis.

Foreign Currency Translation — Assets, liabilities, gains, and losses denominated in foreign currencies are translated at exchange rates at the date of valuation. The resulting net realized and unrealized foreign exchange gains and losses are recorded in net realized and unrealized gains (losses) on trading activities in the statements of operations.

Income Taxes — Income taxes are not provided for by the Partnership because taxable income or loss of the Partnership is includable in the income tax returns of the partners.

Net Income (Loss) Per Unit — Net income (loss) per unit of partnership interest is equal to the change in net asset value per unit from the beginning of the period to the end of the period. Unit amounts are rounded to whole numbers for financial statement presentation.

3.	ADVISORY AGREEMENT AND PARTNERSHIP AGREEMENT

The Advisor is the sole trading advisor to the Partnership.

The General Partner and limited partners share in the profits and losses of the Partnership in proportion to the number of units or unit equivalents held by each partner. However, no limited partner is liable for obligations of the Partnership in excess of its capital contribution and net profits or losses, if any. The General Partner owned no direct interest in the Partnership during the nine month periods ended September 30, 2008 and 2007.

Distributions (other than redemption of units), if any, are made on a pro rata basis at the sole discretion of the General Partner.

The Partnership incurs no expenses. The limited partners are responsible for expenses incurred in connection with the Partnership’s activities. These expenses include, but are not limited to, all costs relating to trading activity, such as brokerage commissions, management and incentive fees, continuing offering expenses and legal, audit, and tax return preparation fees.

Partner contributions occur as of the first day of any month at the opening net asset value. Limited partners may redeem any or all of their units as of the end of any month at net asset value per unit on 10 days prior written notice to the General Partner. The General Partner may suspend redemptions of units of the Partnership’s investments that are illiquid only if the Partnership’s ability to withdraw capital from any investment is restricted. The Partnership will be dissolved on December 31, 2037, or upon the occurrence of certain events, as specified in the limited partnership agreement (the “Agreement”).

4.	DERIVATIVE FINANCIAL INSTRUMENTS

The Partnership trades derivative financial instruments that involve varying degrees of market and credit risk. Market risks may arise from unfavorable changes in interest rates, foreign exchange rates, or the fair values of the instruments underlying the contracts. All contracts are stated at fair value, and changes in those values are reflected in the change in net unrealized trading gains (losses) on open contracts in the statements of operations.

Credit risk arises from the potential inability of counterparties to perform in accordance with the terms of the contract. The credit risk from counterparty nonperformance associated with these instruments is the net unrealized gain, if any, included in the statements of financial condition. Forward contracts are entered into on an arm’s-length basis with RBS. For exchange-traded contracts, the clearing organization functions as the counterparty of specific transactions and, therefore, bears the risk of delivery to and from counterparties to specific positions, which mitigates the credit risk of these instruments. At September 30, 2008 and December 31, 2007 estimated credit risk with regard to forward contracts was $389,088 and $2,411,929, respectively.

The Partnership trades in exchange-traded futures contracts on various underlying commodities, foreign currencies, and financial instruments, as well as forward contracts on foreign currencies. Fair values of futures and forward contracts are reflected net by counterparty or clearing broker in the statements of financial condition.

The Partnership’s funds held by, and cleared through, MFG, Credit Suisse and RBS are required to be held in segregated accounts under rules of the CFTC. These funds are used to meet minimum margin requirements for all of the Partnership’s open futures positions as set by the exchange where each contract is traded. These requirements are adjusted, as needed, due to daily fluctuations in the values of the underlying positions. Certain positions may be liquidated, if necessary, to satisfy resulting changes in margin requirements.

5.	FINANCIAL GUARANTEES

6.	FAIR VALUE MEASUREMENTS

The Partnership segregates its investments into three levels based upon the inputs used to derive the fair value. “Level 1” investments use inputs from unadjusted quoted prices from active markets. “Level 2” investments reflect inputs other than quoted prices, but use observable market data. “Level 3” investments are valued using unobservable inputs. These unobservable inputs for “Level 3” investments reflect the Partnership’s assumption about the assumptions market participants would use in pricing the investments. As of September 30, 2008, the Partnership did not have any positions in “Level 3”.

The following is a summary of the inputs used in valuing the Partnership’s assets and liabilities at fair value:

			Fair Value Measurements

Description	Fair Value as of September 30, 2008		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Other Unobservable Input (Level 3)

ITEM 2.

Management’s Discussion and Analysis of Financial Condition and Results of Operations

Introduction

Reference is made to Item 1, “Financial Statements.” The information contained therein is essential to, and should be read in conjunction with, the following analysis.

Operational Overview

Man-AHL Diversified I L.P. (the “Partnership”) is a speculative managed futures fund which trades through its investment in Man-AHL Diversified Trading Company L.P. (the “Trading Company”) pursuant to the AHL Diversified Program, directed on behalf of the Partnership by Man-AHL (USA) Limited. The AHL Diversified Program is a futures and forward price trend-following trading system, entirely quantitative in nature, and implements trading positions on the basis of statistical analyses of past price histories. The AHL Diversified Program is proprietary and confidential, so that substantially the only information that can be furnished regarding the Partnership’s results of operations is contained in the performance record of its trading. Past performance is not necessarily indicative of its futures results. Man Investments (USA) Corp., the general partner of the Partnership (the “General Partner”) does believe, however, that there are certain market conditions, for example, markets with pronounced price trends, in which the Partnership has a greater likelihood of being profitable than in other market environments.

Capital Resources and Liquidity

Units may be offered for sale as of the beginning, and may be redeemed as of the end, of each month.

The Partnership raises additional capital only through the sale of Units and capital is increased through trading profits (if any) and interest income. The Partnership does not engage in borrowing. The Partnership, not being an operating company, does not incur capital expenditures. It functions solely as a passive trading vehicle, investing the substantial majority of its assets in the Trading Company. Its remaining capital resources are used only as assets available to make further investments in the Trading Company and pay Partnership level expenses. Accordingly, the amount of capital raised for the Partnership should not have a significant impact on its operations.

Partnership assets not invested in the Trading Company are maintained in cash and cash equivalents in bank accounts or accounts with the JPMorgan Chase Bank, N.A. (the “Broker”) and are readily available to the Partnership. The Partnership may redeem any part or all of its limited partnership interest in the Trading Company at any month-end at the net asset value per unit of the Trading Company. The Trading Company’s assets are generally held as cash or cash equivalents which are used to margin futures and forward contracts and other over-the-counter contract positions and are withdrawn, as necessary, to pay redemptions (to the Partnership and other investors in the Trading Company). Other than potential market-imposed limitations on liquidity, due, for example, to limited open interest in certain futures markets or to daily price fluctuation limits, which are inherent in the Trading Company’s futures trading, the Trading Company’s assets are highly liquid and are expected to remain so.

There have been no material changes with respect to the Partnership’s critical accounting policies, off-balance sheet arrangements or disclosure of contractual obligations as reported in the Partnership’s Form 10 filed January 28, 2008 and amended March 26, 2008.

Results of Operations

Due to the nature of the Partnership’s trading, the results of operations for the interim period presented should not be considered indicative of the results that may be expected for the entire year.

Periods Ended September 30, 2008:

		30-Sep-08				30-Jun-08				31-Mar -08
Ending Equity		$	162,663,046			$	120,905,168			$	89,361,244

Three months ended September 30, 2008:

Net assets increased $41,757,878 for the three months ended September 30, 2008. This increase was attributable to subscriptions in the amount of $59,372,518 redemptions in the amount of $1,743,697 and a net loss from operations of $15,870,943.

Management Fees of $1,127,974, brokerage commissions of $246,259 and servicing fees of $393,316 were paid or accrued, and interest of $800,286 was earned or accrued on the Partnership’s cash and cash equivalent investments, for the three months ended September 30, 2008.

Nine months ended September 30, 2008:

Net assets increased $103,107,656 for the nine months ended September 30, 2008. This amount represents subscriptions in the amount of $115,503,154, redemptions in the amount of $9,395,158 and a net loss from operations of $3,000,340.

The Partnership’s other expenses paid or accrued for the nine months ended September 30, 2008 were $226,774.

Three months ended September 30, 2008:

The reversal of several major trends and volatile market conditions contributed to losses in this period. Commodities suffered declines as the prospect of weaker global economic growth raised concerns over future demand.

Energy trading produced losses early in the period, as long positions across a number of markets suffered from a correction in prices. Losses in energy trading were caused by long positions in crude oil as prices fell 11.4% and continued to decline in August. Long positions in natural gas caused losses in July, but short positions in natural gas led to improved performance in August. Short positions in crude oil and oil related products reaped strong rewards in September as prices fell after Hurricane Ike shifted its course away from the Gulf of Mexico.

Trading in agriculturals resulted in losses in both July and August as positions in corn, cocoa, wheat, coffee and soybeans incurred losses. In September, positions cotton, wheat and corn proved particularly profitable.

Losses were accrued by short UK Gilt trades in July and pessimism over the outlook for the global economy boosted returns from the bond sector in August, particularly for long positions in Japanese

bonds, Australian bonds and UK Gilts. In September, long positions in bonds suffered after prices fluctuated and investors’ appetite for risk ebbed and flowed over the month.

Currency trading posted some gains early in the period through long Mexican peso and Brazilian real positions against the US dollar, but these were offset by losses from long positions in the euro versus the US Dollar and British pound and Australian dollar versus the US Dollar. The US Dollar rallied during July and August amid positive corporate earnings and supportive comments from US officials. Short positions in various major currencies against the US dollar detracted from returns in September. The US currency weakened mid-September on concerns over the longer-term consequences of the US Treasury’s proposed financial bailout package.

Equity markets were volatile over the period. After registering mixed performance in July, equity markets advanced in August after positive earnings announcements and then severely declined in September as the financial sector came under pressure. Short positions in various stock indices were profitable in September as the FTSE 100, Nikkei and Hang Seng plunged over 13%.

Three months ended June 30, 2008:

Trading in oil and gas markets proved particularly profitable over the period, where long positions in crude oil and natural gas drove gains. Crude oil surged to new highs during the period and natural gas prices rose sharply amid increased demand from the power sector.

Long crude oil positions registered strong gains as West Texas Intermediate (“WTI”) rose 11.7% in April. A record high of US $119.70 per barrel was reached on April 25, as a weakening US dollar, unexpected falls in US inventories and production difficulties drove prices higher. Long positions in products derived from crude oil, such as RBOB gasoline, heating oil and gas oil, also made gains as prices rose sharply. WTI sustained its rise in May. A new closing high above US $132 per barrel was reached amid worries that demand would outstrip supply within the next few years and on the back of robust demand from China ahead of the Olympics. Meanwhile, OPEC continued to insist that there was no shortage of supply in the market and that elevated prices were a consequence of US dollar weakness and investor speculation. WTI hit fresh highs again in June as geopolitical tensions and concerns about disruptions to output in Nigeria intensified, overshadowing Saudi Arabia’s pledge to provide more crude supplies.

Increasing inflationary pressures and changing interest rate expectations proved beneficial for bond and interest rate trading during the period as short positions in Eurobonds and Euribor contributed to performance. Prices fell in June on heightened speculation that the European Central Bank would lift interest rates after eurozone inflation continued to rise. Profits were slightly offset, however, by long positions in Asian equities and various equity indices as markets came under pressure on fears over stagflation and falling confidence in the financial and housing sectors.

The period highlighted the increasingly difficult task facing the world’s central banks. The need to balance the risks to growth and the risks of accelerating inflation saw a continued divergence in monetary policy over the month. In April, the Bank of England and Federal Reserve took action to protect growth, both lowering interest rates by 0.25%, while the European Central Bank focused on controlling inflation and left base rates unchanged at 4%. Both the Bank of England and European Central Bank left interest rates unchanged over the months of May and June.

In currency markets, the US dollar regained some ground early in the period as investors speculated that the latest decrease in US interest rates may mark the end of the current loosening cycle. The general improvement in sentiment witnessed during April gave strength to the US dollar, which rallied against the euro and Japanese yen towards the end of April, negatively affecting our currency positions. May and June witnessed US dollar weakness and investor speculation. In May, the Australian dollar hit a 24-year high against the US dollar on the back of surging commodity prices and disappointing US consumer confidence figures, which resulted in gains from long Australian dollar positions.

Equity markets began to recover in April from the heavy declines they registered in the first quarter with the S&P 500, FTSE 100 and Nikkei 225 ending up over 4%, 6% and 10%, respectively. Global equity markets continued to trend higher in May as encouraging economic data releases in the US bolstered investor sentiment and dampened talks of a recession. Global equities suffered a sharp sell-off in June, however, with the financial sector driving losses, after persistent speculation that further sub-prime related writedowns were imminent. The FTSE 100 and S&P 500 lost around 7% and 9%, respectively, while the MSCI Asia Pacific fell 8.8%. The slide in equities and gains in commodities increased gold’s appeal, the precious metal rose 4.3% over the month June.

Three months ended March 31, 2008:

Equity markets suffered heavy losses during the quarter as concerns over the health of the financial system intensified and the outlook for the US economy deteriorated. January saw the largest declines with a number of European and Asian indices registering double-digit monthly losses. Conditions improved in February and March but equities continued to trend lower and markets remained highly volatile. The sharp sell-off in equity markets came despite the Federal Reserve slashing its target funds rate from 4.25% to 2.25% and central banks throughout the world injecting additional funds into money markets to increase liquidity. The Federal Reserve’s decision to cut rates aggressively put further downward pressure on the dollar. The US currency slumped to lifetime lows against the euro and Swiss franc and sank to a multi-year low against the Japanese yen. The weakness of the US dollar sent commodity prices sharply higher. Oil rose to a series of lifetime highs, spending most of the second half of the quarter above US $100 per barrel, while gold, base metal and agricultural prices also climbed to record highs.

Trading within agricultural markets made gains across the majority of contracts, with corn trading providing the largest contribution. Soy-based products rose to record highs during February on speculation that increased Chinese demand would cut into US inventories, although March saw a retraction in prices, paring earlier gains from long positions. Prices in soybean oil declined as Chinese importers surprisingly cancelled an order and US farmers stated that a greater proportion of land would be allocated to soy products in the near-term.

Bond trading accrued profits as Japanese bonds and US Treasuries led the way. Disappointing US economic data saw investors switching out of riskier asset classes and into government paper; sending the 2-year US Treasury yield from 3.05% on December 31, 2007 to 1.34% by mid-March. Long positions in Japanese bonds also proved beneficial on increased speculation that the Bank of Japan would cut interest rates to boost economic growth. However, gains were slightly offset by short positions in Australian bonds as investors became concerned over the impact of the credit crunch on economic growth.

Currency trading contributed excellently during the period. The quarter saw the US dollar continue to weaken against most major currencies due to ongoing concerns regarding the credit crisis and the US housing market. As a result, long positions in various currencies, in particular the Swiss franc, against the US dollar proved highly beneficial. March witnessed the euro hitting a record high of US $1.5846, as the European Central Bank (“ECB”) showed no indication of cutting interest rates in the near future.

Energy delivered a solid profit for the quarter as a weakening US dollar and increased demand supported price rises. Long positions in crude oil were beneficial despite the commodity sliding below US $90 at the beginning of the period. However, concerns that OPEC may cut production levels and a disruption to oil production in Nigeria sent prices higher, closing at a record high of US $110.33 per barrel on March 13. Distillate products such as gas oil and heating oil followed the upward trend of crude, accruing strong profits via our long positions.

Precious metals trading made a solid profit as long positions in gold, silver and platinum made gains. Gold rocketed upwards during the start of the period, eventually climbing above the US $1000 mark in

mid-March. Elevated global inflation, a deteriorating US economy and a weak US dollar all supported the rise in gold, silver and platinum. In the base metals component, positive trading in copper offset losses from aluminum.

Trading in short-term interest rates posted a firm gain over the first quarter despite market volatility. Long positions in Eurodollar and Euribor contracts posted the largest part of gains as investors bet on rate reductions in the US and Europe as turmoil swept through global markets. However, these earlier gains were reduced as hawkish rhetoric from the ECB indicated that interest rates for the eurozone would remain stable in the near-term.

Stock market trading posted a gain over the quarter, with short positions in the Nikkei, TOPIX and S&P 500 proving particularly fruitful. Serious concerns over the US economy prompted a large scale investor switch out of equities, with rapidly falling Asian markets reversing some of the gains accrued in 2007. Short exposure to European markets such as the Euro Stoxx, CAC40 and Dax also contributed to gains. However, some profits were reversed as the Federal Reserve intervened to calm markets with a 75bps federal funds rate cut, sending indices higher at the end of March.

Three months ended September 30, 2007:

Equities fell sharply in July as concerns intensified over the sub-prime mortgage sector and credit markets more generally. The FSTE 100 suffered its largest weekly decline in over four years, while the S&P 500, Nikkei 225 and Dax also suffered heavy losses. The MSCI World finished lower for a second successive month in July, prompting speculation that the five-year equity rally may be drawing to a close. Equity markets declined sharply in August due to an unprecedented lack of liquidity in individual stocks as investor sold off liquid assets to meet financial obligations elsewhere.

A number of central banks, including the Federal Reserve, the ECB and Bank of Japan, intervened in August to provide liquidity in money markets and limit damage to the economy. That eventually led to a very significant rebound for markets in the US and most major markets. Equity markets continued to rise over the month of September.

The US Dollar and the Japanese yen closed higher against many major currencies in August after gaining sharply as carry trades unwound in mid-August before losing ground. Currency trading was profitable in September, particularly trades in the euro and Canadian dollar against the US dollar. Positions in various currencies against the US dollar were particularly successful in September due to the dollar’s continued depreciation, weighed by greater growth risks and prospects of further interest rate cuts.

Trading in energy markets contributed positively to returns in the beginning of the period but did not offset early losses incurred from the bond, stock, currency, interest rate and agricultural markets. Performance in July was driven by long crude oil and short natural gas positions. Crude oil prices moved up, benefiting long positions over the majority of July, spurred by supply concerns amid reduced shipment from Angola, unrest in Nigeria’s oil industry and refinery faults in the US. Long positions in crude oil suffered in August and scaled back to limit exposure. In September, commodity trading was profitable, particularly in crude oil, gold and wheat products as strong trending behavior materialized. Crude oil reached a record high in September on the back of dwindling supplies, the threat of a potential tropical storm in the Gulf of Mexico and renewed violence in Nigeria.

Three months ended June 30, 2007:

Significant profits from trading in bond, interest rates, stocks and currencies markets drove gains over the period, while positions in metal, energy and agricultural sectors posted losses.

Currency trading proved to be the major force behind April’s profits, as currency markets saw the British pound rise above the US $2 mark for the first time in fifteen years after a sharp rise In UK Inflation. The euro also broke records, reaching its highest ever level against the US dollar on mounting concerns over the US economy and data indicated that German business confidence remained elevated in April. The European single currency also hit another all-time high against the Japanese yen. Support weakened for the Asian currency as the Bank of Japan slashed its inflation forecast to almost zero and kept interest rates unchanged at 0.5%. Currency trading also made strong gains in June. Profits were led by short positions in the Japanese yen against the US dollar as the yen fuelled carry trade continued to reap rewards. The Bank of Japan kept interest rates at 0.5%, and despite assurances that increases will still be made, contrary to the current deflationary period, analysts do not see a tightening of yields between Japan and the US in the short-term. The Australian dollar appreciated against the US dollar as unexpectedly good employment data caused investors to price in a further interest rate rise from the current level of 6.25%. Unemployment fell from 4.4% in April to May’s 4.2% figure, increasing expectations of interest rate rises and demand for the nation’s high-yielding assets. In June, the Japanese yen fell to multi-year lows against the US dollar, British pound and other high-yielding currencies.

Bond trading produced a significant return during the period, driven by short positions in US treasuries and Euro bonds. Renewed optimism for the US economy drove US treasuries lower in May after strong manufacturing and payroll data prompted speculation that interest rates would be left on hold for the rest

of the year. Euro bonds also fell in May as German consumer confidence rose boosted by positive corporate sentiment. Further positive contributions came from trades in UK Gilts and Euro BOBL.

Government bond markets endured a turbulent beginning to June as yields rose sharply. The 10-year US Treasury yield surged above 5.2% as a raft of strong economic data dashed hopes of an early interest rate cut in the US. In Europe, the European Central Bank raised rates to a six-year high of 4%, while expectations mounted that rates would continue to rise in the UK. Gains in June were attributable to short positions in US treasuries and Australian bonds.

Within interest rate markets, positions in Euribor, Eurodollar and short Sterling accounted for the majority of profits during the period. Short Euribor posted the greatest gains as prices slid in May as strong eurozone data on manufacturing, employment, business and investor confidence and M3 money supply prompted the European Central Bank to pave the way for future interest rate increases. Short Eurodollar posted strong gains as markets reassessed their outlook for US rates. A combination of robust data from the housing market and inflationary pressures remaining above the Fed’s preferred range caused investors to scale back their expectations of an interest rate cut. Short Sterling positions proved well placed as the Bank of England raised rates to 5.5% and few were willing to rule out future near term increases.

Central bank activity during the period saw the Bank of England raise interest rates by 0.25% to 5.5%, their highest level since 2001. While in Europe and the US, upbeat data releases led to speculation that the European Central Bank would raise rates and that the US Federal Reserve would hold rates steady for the duration of the year.

Solid gains were accrued from the stock index sector as equity markets rose strongly over the first half of April. Long positions in major European bourses such as the DAX 30, Euro Stoxx and CAG 40 proved profitable as M&A activity drove indices upwards. On the downside, Japanese indices slightly offset gains through long positions in the Topix and Nikkei 225. Concerns over the US economy affected both as Japanese exporters with a strong US client base suffered heavily, in particular, the technology and automobiles sectors. After China’s economy expanded at a faster-than-expected rate in the first quarter of 2007, the period saw expectations that the government may raise interest rates to prevent overheating. This caused China’s stocks to fall before recovering to end up in April. Global equity markets generally rose in April and May. In April, the S&P 500 hit a new six-year high and the Dow Jones broke through 13000 for the first time. The S&P 500 and the Dow Jones reached new highs again in May. The Chinese Shanghai composite index broke through the 4000 barrier for the first time in its history in May before falling back due to stamp duty increases.

Three months ended March 31, 2007:

At the start of the year, equity markets trended upward, particularly in the US, with the Dow Jones hitting a series of fresh highs as optimism grew over the Fed’s ability to engineer a soft landing. Towards the end of February, a sharp fall in Chinese equities triggered a dramatic sell-off in world equity markets as concerns mounted over the unwinding of the yen carry trade and the health of the US economy. World stocks suffered a tumultuous period in March as concerns over the US sub-prime mortgage sector weighed on investor sentiment and hopes faded of a near-term cut in US interest rates. In currency markets, the US dollar fell to a two-year low against the euro in March as the US economic outlook deteriorated. In January, the Bank of Japan unexpectedly left interest rates on hold at 0.25%, causing the yen to slide to a four-year low against the US dollar. However, at the end of February and in early March, increased risk aversion prompted investors to unwind carry trades, resulting in the Japanese currency surging against high-yielding currencies. The Japanese yen appreciated against the US dollar over the quarter. Crude oil prices ended higher over the first quarter. The West Texas Intermediate fell briefly below US $50 in January. However, oil prices rebounded after President George W. Bush announced in his State of Union address that the US government would double the country’s Strategic Petroleum Reserves. Oil prices rallied further to a six-month high in late March as concerns grew over the diplomatic stand-off between Britain and Iran.

Performance from the agriculturals sector was positive over the period. The largest contribution came from long soybean positions in February, after prices reached US $7.91 a bushel, the highest since 2004 and up 7.5% over the month. Long positions in corn, however, proved particularly disadvantageous after prices retreated in March as increased risk aversion prompted investors to reduce exposure.

The bond sector posted a loss in the first quarter, despite a solid performance witnessed in January. Trading in UK Gilts made the greatest contribution to profits over the period, with gains in January as short positions benefited from the Bank of England’s shock interest rate hike. However, losses were suffered from short positions in US Treasuries as concerns over a global slowdown mounted in February and investors sold stocks for the safe haven of government bonds. Similarly, short positions in UK Euro bund contracts were affected by this concern.

The currency sector struggled to make headway in the first quarter. Long positions in the Australian dollar against the US dollar profited as risk appetite returned in March. Traders bought into the high-yielding Australian currency as part of their carry trade positions. However, losses incurred from the long positions in the British pound against the US dollar undermined overall returns.

The energy sector sustained a modest loss during the first quarter. Natural gas was the largest detractor from performance while RBOB gasoline and crude oil contributed positive results. At the start of the quarter, short positions in natural gas proved detrimental after a sharp increase in demand for heating and weather concerns spurred natural gas prices higher.

The metals complex posted a slight gain over the period. Long positions in nickel, gold and lead contributed gains, while zinc, aluminum and silver trades held back performance. Nickel prices rose over the majority of the period, reaching a record high in mid March against a backdrop of both robust levels of demand and low inventories. However, exposure to zinc detracted from performance, particularly in January, after prices fell on rising inventory levels and news that Dow Jones will reduce the metals weighting in its Commodity Index.

Trading within short-term interest rate markets detracted slightly from the overall performance of the program. The greatest contribution to profits came from well placed short sterling contracts in January as the Bank of England raised interest rates. However, interest rate trading proved less successful in February and March after short positions in Eurodollar and Euribor contracts suffered. In the US, after maintaining interest rates at 5.25%, Ben Bernanke, the chairman of the Federal Reserve, stated that there are some indications inflation pressures are beginning to diminish, while housing data caused concern among investors and sent Eurodollar prices up.

Trading within the stock sector incurred losses. A sharp sell-off in equities at the end of February resulted in losses across most global equity indices, with positions in S&P 500, NASDAQ and Hang Seng adversely affected. The main detractors over the quarter included long positions in Nikkei 225 and TOPIX indices, the former dropping -3.3% in a single day in March, as concerns over the unwinding of the yen carry trade prompted heavy selling in equities. Long positions in the Australian SPI200 Index and South African All Index, however, gained solid profits.
