Northern Trust Investments, Inc. is an investment adviser to the Northern Institutional Funds - Diversified Assets Portfolio. The Northern Trust Company of Connecticut and Northern Trust Investments, Inc. are both indirect subsidiaries of Northern Trust Corporation.

(2) The Fund had approximately $14,820,000 of net sales in the Diversified Assets Portfolio of the Northern Institutional Funds during the period ended September 30, 2011.

* During the current period, a portion of the underlying investments’ value in these Sub-Funds was held in a side pocket arrangement. The Fund will not be able to redeem such value from any particular underlying investment until such amount is released from its respective side pocket arrangement. In the aggregate, approximately 0.2% of the Fund’s net assets are in side pocket arrangements. The Fund is not able to estimate the timing of receipt of such amounts.

Percentages shown are based on Net Assets. The classifications shown on the schedule of investments and the table herein are unaudited.

Sub-Fund investments are non-income producing.

At September 30, 2011, the investment strategies for NT Alpha Strategies Fund’s investments as a percentage of total net assets were diversified as follows:

At September 30, 2011, the NT Alpha Strategies Fund’s Sub-Funds’ investments were domiciled as follows:

COUNTRIES	COST		VALUE
Cayman Islands – 10.0%		$37,864,000		$49,075,000
Isle of Man – 2.5%		12,000,000		12,509,000
United States – 80.7%		369,975,000		395,404,000
Total				$456,988,000

Various inputs are used in determining the value of the Fund’s investments. These inputs are summarized in three levels listed below:

Level 1 – Quoted market prices in active markets for identical securities on the measurement date and on an ongoing basis.

Level 2 – Other observable inputs. The Fund utilized the following valuation technique on Level 2 investments: The Fund valued certain securities at the net asset value, which in turn is based on valuation data obtained from external valuation sources for which those securities may have the ability to be fully redeemed at the net asset value in the “near term.”

Level 3 – Valuation based on inputs that are unobservable and significant. The Fund utilized the following valuation technique on Level 3 investments: The Fund valued certain securities at the net asset value, which in turn is based on valuation data obtained from external valuation sources for which those securities may have the ability to suspend redemptions or implement other restrictions on liquidity, such as side-pockets or lock-up periods greater than 180 days.

The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities and other financial instruments, if any. Following is a summary of the inputs used in valuing the NT Alpha Strategies Fund’s investments, which are carried at fair value, as of September 30, 2011. The strategy classifications listed below are unaudited.

* The fair value of Transfers In and/or (Out) of Level 3 were measured using the fair value as of the end of the period. The Transfers Out of Level 3 noted above were due to expiration of lock agreements and the consolidation of side pocket agreements of the underlying Sub-Funds between measurement dates.

The amount of total unrealized loss on investments in Level 3 securities still held at September 30, 2011 was approximately $(6,090,000), which is included in the Statement of Operations as a part of the net change in unrealized appreciation (depreciation) on investments.

(3) Portfolio turnover rate includes initial and additional investments in Sub-Funds, as well as partial and full withdrawals from Sub-Funds.

(4) Per unit information is calculated using the average units outstanding method.

(5) The net expense and net investment loss ratios include an additional reimbursement on advisory fees incurred in connection with the investment of uninvested cash in an affiliated money market fund of approximately $30,000 and $68,000, which represents 0.01% and 0.02% of average net assets for the six months ended September 30, 2011 and fiscal year ended March 31, 2011, respectively. Absent the additional reimbursement, net investment loss and expense reimbursement would have been decreased by a corresponding amount.

NT ALPHA STRATEGIES FUND

NOTES TO THE FINANCIAL STATEMENTS

1. ORGANIZATION

NT Alpha Strategies Fund (the “Fund”) is a Delaware statutory trust and is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as a closed-end, diversified management investment company. The Fund’s investment objective is to seek attractive risk-adjusted rates of return through investment in a diversified portfolio of assets. The Fund operates as a “Fund-of-Funds,” investing, either directly or indirectly, in a group of funds or other pooled investment vehicles (the “Sub-Funds”) managed by investment advisers selected by the Fund’s investment manager. The Fund seeks to provide investors with exposure to alternative investment strategies by investing in diversified markets and instruments.

U.S. tax-exempt investors and non-U.S. investors may not invest directly in the Fund, but rather should invest in one of the two following “Feeder Funds,” both of which invest substantially all of their assets in the Fund: (1) Northern Trust Alpha Strategies Fund, Q.P., which is open to U.S. tax-exempt investors and non-U.S. investors that are both Accredited Investors and Qualified Purchasers (as such term is defined in Section 2(a)(51) of the 1940 Act) or (2) Northern Trust Alpha Strategies Fund, which is open to U.S. tax-exempt investors and non-U.S. investors that are Accredited Investors, but not Qualified Purchasers.

The Northern Trust Company of Connecticut (“NTCC”), an indirect subsidiary of Northern Trust Corporation (“NTC”), serves as the investment manager.

The Northern Trust Company (“Northern Trust”), is the custodian, fund accountant, transfer agent and sub-administrator of the Fund.

Northern Trust Investments, Inc. (“NTI”), an indirect subsidiary of NTC, serves as the administrator of the Fund.

Northern Trust Securities, Inc., (“NTSI”) (the “Placement Agent”), a subsidiary of NTC, serves as a placement agent of the Fund.

2. SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. These policies are in conformity with accounting principles generally accepted in the United States of America or “GAAP”. The preparation of financial statements in conformity with GAAP 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 income and expenses during the reporting period. Actual results may differ from those estimates.

A) VALUATION OF SECURITIES Investments in Sub-Funds are valued at fair value, as determined by NTCC, pursuant to delegation from the Board of Trustees (the “Board”) of the Fund. In determining the fair value of each Sub-Fund, NTCC will take into account the estimated net asset value of such Sub-Fund provided to the Fund by the Sub-Fund, as well as any other considerations that may, in NTCC’s judgment, increase or decrease such estimated value. Accordingly, because of the inherent uncertainty of these valuations, these estimated values may differ significantly from the values that could have been used had a readily available market for the investments existed, and the differences could be material. Cash equivalents are valued at cost, which approximates fair value.

B) CASH AND CASH EQUIVALENTS The Fund treats all financial instruments with original maturities of 3 months or less as cash equivalents. Cash and cash equivalents held in the Fund are shown on the accompanying Schedule of Investments.

C) INVESTMENT TRANSACTIONS, INCOME AND EXPENSES Investment transactions are recorded as of the trade date. The Fund determines the gain or loss realized from investment transactions by using an identified cost basis method. Interest income and expenses are recognized on an accrual basis. The Fund does not currently intend to make any distributions.

D) FEES AND EXPENSES The Fund is responsible for paying administrative and operating expenses. In addition, the Fund is responsible for paying the operating expenses of the Feeder Funds.

The Fund also is responsible for fees payable by the Sub-Funds to their respective advisers (collectively, the “Advisory Fees”) in proportion to the Fund’s investments in the Sub-Funds. The Advisory Fees will vary, but they will typically consist of a management (asset-based) fee and an incentive fee. Management fees typically range between 1% and 2% of a Sub-Fund’s net asset value per year and incentive fees typically range between 10% and 25% of the Sub-Fund’s net new profits. These Advisory Fees are accounted for in the valuations of the Sub-Funds (which are reported in these financial statements net of such fees) and are not included in the Statement of Operations.

E) FEDERAL INCOME TAXES The Fund operates and has elected to be treated as a partnership for federal income tax purposes. Accordingly, no provision for the payment of federal, state or local income taxes has been provided. Each unitholder is individually required to report on its own tax return its distributive share of the Fund’s taxable income or loss.

SEPTEMBER 30, 2011 (UNAUDITED)

As of March 31, 2011 the Fund did not have uncertain tax positions that would require financial statement recognition or disclosure. The Fund’s federal tax returns filed for the fiscal years ended March 31, 2008 through March 31, 2010 remain subject to examination by the Internal Revenue Service.

3. RELATED PARTY, INVESTMENT MANAGEMENT AND OTHER AGREEMENTS

As compensation for investment management services, NTCC is entitled to receive a 1.00% per annum fee of the Fund’s net asset value, payable quarterly in arrears, calculated as of the last business day of each quarter. NTCC has agreed to reimburse the Fund for all operating expenses, exclusive of management fees, that exceed 0.50% per annum of the Fund’s net asset value. The reimbursement described above is voluntary. There was no reimbursement for the period ended September 30, 2011 as expenses described above did not exceed the threshold.

As compensation for services rendered as transfer agent, including the assumption by Northern Trust of the expenses related thereto, Northern Trust receives a 0.01% per annum fee of the Fund’s net asset value, payable monthly in arrears, calculated as of the last business day of each month.

For compensation as custodian and fund accountant, Northern Trust receives an amount based on a pre-determined schedule of charges approved by the Board.

The Fund has an administration agreement with NTI for certain administrative services. Pursuant to their administration agreement with the Fund, the administrator is entitled to receive a 0.10% per annum fee of the Fund’s net asset value payable monthly in arrears calculated as of the last business day of each month. NTI has retained Northern Trust as sub-administrator. Northern Trust is paid directly by NTI for its services.

NTI has agreed to reimburse the Fund for all administration, sub-administration, custody and transfer agent fees that exceed 0.30% per annum of the Fund’s net asset value. The reimbursement described above is voluntary. There was no reimbursement for the period ended September 30, 2011 as expenses described above did not exceed the threshold.

The Placement Agent solicits subscriptions for Common Units (as defined below) on a “best efforts” basis. The Fund does not pay a placement fee to the Placement Agent and common unitholders do not pay any sales charges or servicing fees.

As of September 30, 2011, NTI’s investment in the Fund was approximately $13,000 (less than 1% of net assets).

The Fund currently invests uninvested cash in the Diversified Assets Portfolio (“DAP” or the “Portfolio”) of Northern Institutional Funds, an investment company which is advised by NTI. The Fund bears indirectly a proportionate share of the Portfolio’s operating expenses. These operating expenses include the advisory, administrative, transfer agency and custody fees that the Portfolio pays to NTI and/or its affiliates. Currently, the aggregate annual rate of advisory, administration, transfer agency and custody fees payable to NTI and/or its affiliate on any assets invested in DAP is 0.35%. However, NTI has agreed to reimburse the Fund for advisory fees otherwise payable to the Fund on any assets invested in DAP. This reimbursement is included on the Statement of Operations as Less expenses reimbursed by investment adviser.

4. CAPITAL TRANSACTIONS

The Fund offers common interests (“Common Units”) in a private placement to qualified investors that are “Accredited Investors” within the meaning given to such term in Regulation D under the Securities Act of 1933, as amended. Common Units are offered monthly. The minimum subscription per investor is $250,000, subject to waiver or modification by NTCC in its sole discretion. Subscriptions are payable in full at the time an investor returns the subscription agreement, which must be at least three business days before the month-end valuation. The net asset value of the Fund is equal to the estimated value of its total assets, minus the estimated sum of its total liabilities, as of the pertinent valuation date. Although common unitholders will not have the right to redeem their Common Units, at the discretion of the Board, and subject to its overall fiduciary duties to all unitholders, the Board intends to make quarterly tender offers of its Common Units at the net asset value as of the applicable tender date. The minimum amount of Common Units that may be tendered is equal to $100,000. Should a Common Unitholder choose to accept any such tender offer, such acceptance must be in writing and must be received by the Fund, as set forth in the notice of such tender offer, within twenty business days from the commencement of such quarterly tender offer. The Fund is authorized to issue preferred units, although none have been offered as of September 30, 2011.

5. INVESTMENT TRANSACTIONS

The Fund had aggregate purchases of $74,866,000 and proceeds from sales of Sub-Funds of $46,603,000 (excluding short-term investments) for the six months ended September 30, 2011.

At September 30, 2011, the estimated cost of investments for federal income tax purposes was $419,839,000. At September 30, 2011, accumulated net unrealized appreciation on investments was $37,149,000 consisting of $46,212,000 gross unrealized appreciation and $9,063,000 gross unrealized depreciation.

6. NET ASSETS

The net assets of the Fund are determined as of the last business day of each calendar month. Profits and losses of the Fund are allocated among the common unitholders based on the balance in each common unitholders account at the beginning of each calendar month.

7. RISK FACTORS

FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK The Sub-Funds may borrow and may utilize various lines of credit, reverse repurchase agreements, “dollar rolls,” issuance of debt securities, swaps, forward purchases, other off-balance sheet derivative transactions and other forms of leverage. While leverage presents opportunities for increasing total return, it has the effect of potentially increasing losses as well. If income and appreciation on investments made with borrowed funds are less than the cost of the leverage, the value of a Sub-Fund’s net assets will decrease. Accordingly, any event which adversely affects the value of an investment by a Sub-Fund would be magnified to the extent leverage is employed. The cumulative effect of the use of leverage in a market that moves adversely to a leveraged investment could result in a substantial loss which would be greater than if leverage were not used. In periods of extreme market volatility, the need to sell assets in a declining market can cause even greater losses, as prices may be artificially depressed. Generally, most leveraged transactions involve the posting of collateral. Increases in the amount of margin that a Sub-Fund is required to post could result in a disposition of Sub-Fund assets at times and prices which could be disadvantageous to the Fund and could result in substantial losses. Creditors’ claims may be senior to the rights of unitholders in the Fund.

Financial Accounting Standards Board (“FASB”) Accounting Standards Codification 820 (“ASC 820”) Fair Value Measurements and Disclosures requires disclosure to assist in understanding the nature and risk of the investments by major category. The table below summarizes the fair value and other pertinent liquidity information of the underlying investments by major category. The strategy classifications shown in the table below are unaudited.

(a) Hedged Equity—The managers in this category seek to identify and select equity securities that will rise in price on the long side and those that will fall in price on the short side. Equity securities make up the large bulk of their underlying exposure. Net exposure ranges from zero to 100%, while gross exposure can be 200% or more. Sub-strategies in this category include Asia Long/Short Equity, Long/Short Equity, U.S. Equity Hedge, Non-U.S. Equity Hedge, Sector Hedge and Equity Market Neutral. The fair values of the investments in this category have been estimated using the net asset value per share (or its equivalent) of the investments. Investments representing approximately 2.7% of the fair value of investments in this category cannot be redeemed because the investments include restrictions that do not allow for full redemptions.

(b) Market Dependent—The managers in this category employ strategies directed more heavily towards the ebbs and flows of markets on a larger scale, as opposed to focusing on the relative attractiveness between individual securities. Managers seek to identify the direction that certain markets

NT ALPHA STRATEGIES FUND 12 SEMIANNUAL REPORT

NT ALPHA STRATEGIES FUND

SEPTEMBER 30, 2011 (UNAUDITED)

will follow over various time periods and position their portfolios accordingly. Sub-strategies in this category include Global Macro, Commodity Trading Advisor, Emerging Markets, Non-U.S. Multi-Strategy and Short Bias. The fair values of the investments in this category have been estimated using the net asset value per share (or its equivalent) of the investments. Investments representing approximately 0.1% of the fair value of investments in this category cannot be redeemed because the investments include restrictions that do not allow for full redemptions.

(c) Market Independent—The managers in this category seek to deliver alpha without subjecting themselves to or relying on beta or general market exposure for performance. They seek to do this by identifying and exploiting various arbitrage opportunities between and among related groups of securities, with the expectation that returns will have a low correlation to the markets in which those securities trade. Sub-strategies in this category include Fixed Income Arbitrage, Convertible Bond Arbitrage, Relative Value and Statistical Arbitrage. The fair values of the investments in this category have been estimated using the net asset value per share (or its equivalent) of the investments. Investments representing approximately 0.1% of the fair value of investments in this category cannot be redeemed because the investments include restrictions that do not allow for full redemptions.

(d) Event Driven—The managers in this category seek to profit from opportunities arising from specific situations affecting individual stocks or unique circumstances in a particular industry, sector or market. These market participants typically specialize in certain sectors of the Event Driven space, utilizing unique skills or knowledge of bankruptcy law, specific market events, or otherwise. Sub-strategies in this category include Distressed, Event Driven and Special Situations. The fair values of the investments in this category have been estimated using the net asset value per share (or its equivalent) of the investments. Investments representing approximately 9.6% of the fair value of investments in this category cannot be redeemed because the investments include restrictions that do not allow for full redemptions.

8. BOARD OF TRUSTEES

Each member of the Board (each, a “Trustee”) who is not an “interested person” of the Fund, as defined in the 1940 Act, receives an annual retainer of $20,000 and $1,500 for each special in-person meeting of the Board or a committee held outside the regular quarterly meetings.

Also, each Trustee who is not an “affiliated person” of the Fund or NTCC and who serves as the Board chair or a committee chair shall receive an additional retainer of $10,000 per annum from the Fund.

At September 30, 2011, there are four Trustees, of which three are not “interested persons” of the Fund. The Fund reimburses those Trustees who are not “interested persons” for all reasonable out-of-pocket expenses incurred by them in performing their duties.

9. NEW ACCOUNTING PRONOUNCEMENTS

On May 12, 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-04, Fair Value Measurement: Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs (“ASU 2011-04”), modifying ASC 820. At the same time, the International Accounting Standards Board (“IASB”) issued International Financial Reporting Standard (“IFRS”) 13, Fair Value Measurement. The objective by the FASB and IASB is convergence of their guidance on fair value measurements and disclosures. Specifically, ASU 2011-04 requires reporting entities to disclose 1) the amounts of and reasons for any transfers between Level 1 and Level 2, and 2) for Level 3 fair value measurements: a) quantitative information about significant unobservable inputs used, b) a description of the valuation procedures used by the reporting entity, and c) a narrative description of the sensitivity of the fair value measurement to changes in unobservable inputs if a change in those inputs might result in a significantly higher or lower fair value measurement. The effective date of ASU 2011-04 is for annual periods beginning after December 15, 2011. At this time, management is evaluating the implications of this requirement and the impact it will have to the Fund’s financial statement disclosures.

10. SUBSEQUENT EVENTS

Management has evaluated subsequent events for the Fund through the date the financial statements were issued, and has concluded that there are no recognized or non-recognized subsequent events relevant for financial statement disclosure.
