Hurricanes Katrina and Rita devastated the southern coast, leaving hundreds of thousands jobless and without homes, and prompting investor fears of high energy prices (which came true) and inflation (which did not). The war in Iraq entered its third year, and the domestic debate about the war intensified. The job market showed some improvement but job creation and wage growth remained sub-par relative to economic growth and corporate profitability. The Fed--concerned about inflation and the frothiness of the housing market--raised overnight lending rates eight times to 3.75%, the highest level in 4.5 years. In response, anxious investors--and Wall Street professionals, in particular--remained skeptical, adopting a wait-and-see attitude. Despite such understandable concerns, the U.S. equity markets have emerged from the bear market of the early 2000s. In fact, since October of 2002, when the market made a post-bubble low, the major U.S. indices have been very strong. So has the economy, both domestically and globally. Over the past year, the U.S. economy showed steady growth of around 3.5%, core inflation excluding energy remained muted at around 2%, and corporate earnings stayed in double-digits, much to the surprise of most strategists. Growth companies in particular saw healthy stock appreciation. Going forward, we see even greater potential for the better growth managers to outperform their benchmarks and the overall markets. Challenges for consumers did not necessarily translate into problems for investors. High energy prices created investment opportunities, and energy stocks outperformed all other sectors. Additionally, high gas prices prompted exploration into both alternative sources of energy and innovative solutions to reducing fuel consumption. The twin effects of productivity and globalization continue to reshape the competitive landscape for dynamic companies. Information technologies no longer attract the same attention, but their effects on companies are more significant than ever. The result is higher productivity, which translates into higher profitability for many corporations. In addition, more businesses are operating on a global scale, and U.S. corporate profits rose dramatically from foreign sales. Emerging economies in Asia, Latin America and Eastern Europe are all contributing to global economic growth, and China, both as a consumer of raw materials and finished goods and as a producer of products for global consumption, shows no signs of diminishing. Consumers have also been affected by these trends. In the United States, a critical mass of consumers adopted high-speed broadband technology. As a result, the Internet has become more fully integrated into day-to-day life as a ubiquitous resource for retail, services, entertainment, education, communication, and business needs. This has created opportunities for dynamic new business models, whether it is Google in the on-line search and advertising space, eBay and auctions, or Apple iPods and downloadable music files. In sum, for the 12 months ended October 31, 2005, the equity markets experienced modest gains with the Dow gaining 6.4%, the Nasdaq up 8.1% and the S&P 500 up 8.7%. While long-term Treasury yields were markedly inconsistent with the Fed's overnight interest rate increases, the yield on the U.S. Treasury 10-year note was 4.57% on October 31, 2005, compared to 4.05% a year earlier. PORTFOLIO MATTERS The Spectra Fund gained 18.84% for the fiscal year, compared to the Russell 3000 Growth Index which returned 8.99%. The Fund's holdings in the information technology sector, at an average weight of 28.11%, were overweight compared to the benchmark and significantly outperformed. Strong IT performers included Google Inc., Apple Computer, Inc., whose iPod technologies continued to show dominant sales, Palm Inc., the market leader in handheld computer solutions, and Verifone Holdings Inc., the global leader in secure electronic payment technologies. Our holdings in the health care sector were underweight compared to the benchmark, at an average weight of 17.59%. Companies contributing to our outperformance in this sector included PacifiCare Health Systems, Inc., a managed care health insurance company, Vertex Pharmaceuticals Incorporated, and Caremark Rx, Inc., one of the nation's largest pharmaceutical firms. During the year some sector shifts were made. We decreased our exposure to biotech and pharmaceuticals, and increased it in health care providers. In the consumer staples sector, we were underweight compared to the benchmark, at an average weight of 6.99%. Here too, the Fund significantly outperformed, bolstered by performances from CVS Corporation, Gillette, and Parlux Frangrances Inc. During the course of the year we shifted our weightings in this sector, decreasing our holdings in internet and catalog retail. In the consumer discretionary sector, the Fund was underweight compared to the benchmark, at an average weight of 10.35%, and underperformed. In this sector, we increased our holdings in personal products throughout the year. Energy stocks accounted for an average weight of 8.52% of the Fund's holdings, an overweight to the benchmark. Despite strong returns in oil and gas drilling companies, including National Oilwell Varco Inc. and Patterson-UTI Energy, Inc., the Fund underperformed the benchmark. Both the materials and industrials sectors were also impacted by rising energy prices and our holdings in these sectors significantly outperformed the benchmark with contributors like Peabody Energy Corporation, the world's largest private sector coal company, and UTi Worldwide, Inc. LOOKING AHEAD At Alger, we look for dynamic, innovative companies regardless of whether the stock markets are dominated by bulls or bears. Our long-term success is not a product of momentum or fads, but that of a highly-disciplined approach grounded in fundamental, bottom-up research, and bolstered by the thorough conviction of our analysts. Looking ahead in 2006, we anticipate a year similar to 2005, with continued strong corporate earnings, and an equity market that increasingly recognizes growth and responds in kind. 2 As we end another fiscal year, we'd like to take the opportunity to thank you for growing with us, and continuing to entrust us with your investment needs.

The Fund's investment objective is capital appreciation. It seeks to achieve its objective by investing primarily in equity securities. The Fund offers Class A and Class N shares. Class A shares were first offered on July 1, 2000 and are generally subject to an initial sales charge. Class Nshares are offered only to Class Nshareholders of record as of January 21, 2005. Each class has identical rights to assets and earnings. The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements. (A) INVESTMENT VALUATION--Investments in securities are valued each day the New York Stock Exchange (the "NYSE") is open as of the close of the NYSE (normally 4:00 p.m. Eastern time). Listed securities for which such information is regularly reported are valued at the last reported sales price or, in the absence of reported sales, at the mean between the bid and asked price, or in the absence of a recent bid or asked price, the equivalent as obtained from one or more of the major market makers for the securities to be valued. Short-term notes are valued at amortized cost which approximates market value. Shares of mutual funds are valued at the net asset value of the underlying mutual fund. Securities included within the Nasdaq market shall be valued at the Nasdaq official closing price ("NOCP") on the day of valuation, or if there is no NOCP issued, at the last sale price on such day. Securities included within the Nasdaq market for which there is no NOCP and no last sale price on the day of valuation shall be valued at the mean between the last bid and asked prices on such day. (B) SECURITIES TRANSACTIONS AND INVESTMENT INCOME--Securities transactions are recorded on a trade date basis. Realized gains and losses from securities transactions are recorded on the basis of the first-in, first-out method. Dividend income is recognized on the ex-dividend date and interest income is recognized on the accrual basis. (C) REPURCHASE AGREEMENTS--The Fund enters into repurchase agreements with approved institutions. The repurchase agreements are collateralized by U.S. Government securities, which are either received and held in physical possession by the custodian or received by such custodian in book-entry form through the Federal Reserve book-entry system. The collateral is valued on a daily basis during the term of the agreement to ensure that its value equals or exceeds the agreed-upon repurchase price to be repaid to the Fund. Additional collateral is obtained when necessary. (E) LENDING OF PORTFOLIO SECURITIES--The Fund lends its securities to financial institutions, provided that the market value of the securities loaned will not at any time 14 SPECTRA FUND NOTES TO FINANCIAL STATEMENTS (CONTINUED) exceed one third of the Fund's total assets, as defined. The Fund earns fees on the securities loaned. In order to protect against the risk of failure by the borrower to return the securities loaned or any delay in the delivery of such securities, the loan is collateralized by cash, letters of credit or U.S. Government securities that are maintained in an amount equal to at least 100 percent of the current market value of the loaned securities. The market value of the loaned securities is determined at the close of business of the Fund and any required additional collateral is delivered to the Fund on the next business day. As of October 31, 2005, there were no securities on loan. (F) DIVIDENDS TO SHAREHOLDERS--Dividends and distributions payable to shareholders are recorded by the Fund on the ex-dividend date. Dividends from net investment income and distributions from net realized gains are declared and paid annually after the end of the fiscal year in which earned. Each class is treated separately in determining the amounts of dividends from net investment income and distributions from capital gains payable to holders of its shares. The characterization of distributions to shareholders for financial reporting purposes is determined in accordance with federal income tax rules. Therefore, the source of the Fund's distributions may be shown in the accompanying financial statements as either from, or in excess of net investment income, net realized gain on investment transactions or return of capital, depending on the type of book/tax differences that may exist. Capital accounts within the financial statements are adjusted for permanent book/tax differences. Reclassifications result primarily from the difference in tax treatment of net operating losses. The reclassification had no impact on the net asset value of the Fund and is designed to present the Fund's capital accounts on a tax basis. (G) FEDERAL INCOME TAXES--It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its investment company taxable income to its shareholders. Provided the Fund maintains such compliance, no federal income tax provision is required. (H) ALLOCATION METHOD--Income, realized and unrealized gains and losses, and expenses are allocated among the Fund's classes based on relative net assets. (I) INDEMNIFICATION--The Fund enters into contracts that contain a variety of indemnification provisions. The Fund's maximum exposure under these arrangements is unknown. The Fund does not anticipate recognizing any loss related to these arrangements. (J) OTHER--These financial statements have been prepared using estimates and assumptions that affect the reported amounts therein. Actual results may differ from those estimates. 15 SPECTRA FUND NOTES TO FINANCIAL STATEMENTS (CONTINUED) NOTE 2--INVESTMENT ADVISORY FEES AND OTHER TRANSACTIONS WITH AFFILIATES: (A) INVESTMENT ADVISORY FEES--The Fund pays its investment adviser, Fred Alger Management, Inc.

Effective February 28, 2005, the Fund has entered into a shareholder administrative services agreement with Alger Services to compensate Alger Services on a per account basis for its liaison and administrative oversight of BFDS and related services. During the year ended October 31, 2005, the Fund incurred fees of $31,552 for these services provided by Alger Services. (C) SALES CHARGES--Purchases of Class A shares of the Fund may be subject to initial sales charges. For the year ended October 31, 2005, the initial sales charges retained by Fred Alger &Company (the "Distributor"), were approximately $1,801. Sales charges do not represent expenses of the Fund. (D) BROKERAGE COMMISSIONS--During the year ended October 31, 2005, the Fund paid Fred Alger & Company, Incorporated ("Alger Inc."), an affiliate of Alger Management, $640,343 in connection with securities transactions.

For the year ended October 31, 2005, the Fund had borrowings which averaged $105,452 at a weighted average interest rate of 2.84%. Written call and put option activity for the year ended October 31, 2005 was as follows: NUMBER OF PREMIUMS CONTRACTS RECEIVED --------- ---------- Options outstanding at October 31, 2004 -- -- Options written 240 $ 207,471 Options closed or expired (240) (207,471) Options exercised -- -- ------- --------- Options outstanding at October 31, 2005 -- $ -- ======= ========= NOTE 5--SHARE CAPITAL: (A) The Fund has an unlimited number of authorized shares of beneficial interest of $.001 par value which are presently divided into two separate classes.

These amounts may be applied against future net realized gains until the earlier of their utilization or expiration. EXPIRATION DATE AMOUNT - --------------- ------------ 2009 $148,683,326 2010 107,067,302 ------------ $255,750,628 ============ NOTE 7--LITIGATION Alger Management has responded to inquiries, document requests and/or subpoenas from regulatory authorities, including the United States Securities and Exchange Commission ("SEC"), the Office of the New York State Attorney General, the Attorney General of New Jersey, and the West Virginia Securities 18 SPECTRA FUND NOTES TO FINANCIAL STATEMENTS (CONTINUED) Commissioner, in connection with their investigations of practices in the mutual fund industry identified as "market timing" and "late trading." On December 16, 2005, Alger Management received from the staff of the SEC a "Wells Notice" which indicated that the staff intends to recommend that the Commission bring civil enforcement action for possible violations of the federal securities laws. "Wells Notices" also have been sent to certain companies affiliated with Alger Management, as well as certain present and former members of its senior management. The Wells Notices arose out of the SEC's staff ongoing investigation of market timing and late trading practices in the mutual fund industry. Alger Management and the other recipients have the opportunity to respond to the staff before the staff makes a formal recommendation. Alger Management plans to send a Wells submission to the staff in January 2006. On August 31, 2005, the West Virginia Securities Commissioner in an ex parte Summary Order to Cease and Desist and Notice of Right to Hearing concluded that Alger Management and Alger Inc. had violated the West Virginia Uniform Securities Act, and ordered Alger Management and Alger Inc. to cease and desist from further violations of the Act by engaging in the market-timing related conduct described in the order. The ex parte order provided notice of their right to a hearing with respect to the violations of law asserted by the Commissioner. Other firms unaffiliated with Alger Management were served with similar orders. Alger Management and Alger Inc. intend to request a hearing for the purpose of seeking to vacate or modify the order. In addition, in 2003 and 2004 several purported class actions and shareholder derivative suits were filed against various parties in the mutual fund industry, including Alger Management, certain mutual funds managed by Alger Management (the "Alger Mutual Funds"), and certain current and former Alger Mutual Fund trustees and officers, alleging wrongful conduct related to market-timing and late-trading by mutual fund shareholders. These cases were transferred to the U.S. District Court of Maryland by the Judicial Panel on Multidistrict Litigation for consolidated pre-trial proceedings. In September 2004, consolidated amended complaints involving these cases (not yet including the West Virginia action) -- a Consolidated Amended Fund Derivative Complaint (the "Derivative Complaint") and two substantially identical Consolidated Amended Class Action Complaints (together, the "Class Action Complaint") -- were filed in the Maryland federal district court under the caption number 1:04-MD-15863 (JFM). In April 2005, a civil lawsuit involving similar allegations was filed by the West Virginia Attorney General and also transferred to the Maryland District Court. The Derivative Complaint alleged (i) violations, by Alger Management and, depending on the specific offense alleged, by its immediate parent, Alger Inc., which is the Distributor of the Alger Mutual Funds, and/or the fund trustee defendants, of Sections 36(a), 36(b), 47, and 48 of the Investment Company Act of 1940 (the "Investment Company Act") and of Sections 206 and 215 of the 19 SPECTRA FUND NOTES TO FINANCIAL STATEMENTS (CONTINUED) Investment Advisers Act of 1940, breach of fiduciary duty, and breach of contract, (ii) various offenses by other third-party defendants, and (iii) unjust enrichment by all the named defendants. The Class Action Complaint alleged, in addition to the offenses listed above, (i) violations, by Alger Management, Alger Inc., their affiliates, the funds named as defendants, and the current and former fund trustees and officers, of Sections 11, 12(a)(2), and 15 of the Securities Act of 1933, Sections 10(b) (and Rule 10b-5 thereunder) and 20(a) of the Securities Exchange Act of 1934 (the "1934 Act"), and Section 34(b) of the Investment Company Act of 1940, (ii) breach of contract by the funds named as defendants, and (iii) unjust enrichment of the defendants. The West Virginia attorney general action also alleges violations of the West Virginia Consumer Credit and Protection Act and other wrongful conduct. Motions to dismiss the Class Action Complaint and the Derivative Complaint were subsequently filed. On November 3, 2005, the district court dismissed both complaints in their entirety with respect to the Alger Mutual Funds and dismissed all claims against the other Alger defendants other than the claims under the 1934 Act and Section 36(b) of the Investment Company Act, with leave to the class action plaintiffs to file amended complaints against those defendants with respect to claims under state law. It is anticipated that orders implementing the rulings will be entered in or about January 2006, and that motions for reconsideration will thereafter be filed. Alger Management does not believe that the Alger Mutual Funds are themselves targets of the regulatory investigations as potential enforcement defendants. The SEC and, in some cases, state government authorities have a variety of administrative and civil enforcement powers, including injunctive powers, authority to assess fines and penalties and order restitution, authority to limit the activities of a person or company and other enforcement powers, that may be exercised administratively or through the courts. Under Section 9(a) of the Investment Company Act, if any of the various regulatory proceedings or lawsuits were to result in a court injunction against Alger Management or Alger Inc., Alger Management would, in the absence of exemptive relief granted by the SEC, be barred from serving as investment adviser/sub-adviser for any registered investment company, including the Fund. While exemptive relief from Section 9(a) has been granted in certain other cases, there is no assurance that such exemptive relief would be granted if sought. In addition, it is possible that these matters and/or other developments resulting from these matters could result in loss of Alger Management personnel, diversion of time and attention of Alger Management personnel, diminishment of financial resources of Alger Management, or other consequences potentially adverse to the Fund. Alger Management cannot predict the potential effect of such actions upon Alger Management or the Fund. There can be no assurance that the effect, if any, would not be material. 20 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Shareholders and Board of Trustees of Spectra Fund: We have audited the accompanying statement of assets and liabilities of Spectra Fund (the "Fund"), including the schedule of investments, as of October 31, 2005, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the four years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. The financial highlights for the year ended October 31, 2001 were audited by other auditors, whose report, dated November 30, 2001, expressed an unqualified opinion on those financial highlights. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Fund's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of October 31, 2005, by correspondence with custodians and brokers. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above, and audited by us, present fairly, in all material respects, the financial position of Spectra Fund at October 31, 2005, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the four years in the period then ended, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP December 12, 2005 21 SPECTRA FUND ADDITIONAL INFORMATION (UNAUDITED) SHAREHOLDER EXPENSE EXAMPLE As a shareholder of the Fund, you incur two types of costs: transaction costs, if applicable, including sales charges (loads) and redemption fees; and ongoing costs, including management fees, distribution (12b-1) fees, if applicable, and other fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example below is based on an investment of $1,000 invested at the beginning of the six-month period starting May 1, 2005 and ending October 31, 2005. ACTUAL EXPENSES The first line for each class of shares in the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you would have paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During the Period" to estimate the expenses you paid on your account during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The second line for each class of shares in the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratios for each class of shares and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs, such as sales charges (loads) and redemption fees. Therefore, the second line under each class of shares in the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

(the "Adviser"). The Trustees who are not "interested persons" of the Fund (the "Independent Trustees") within the meaning of the Investment Company Act of 1940 (the "1940 Act") also met separately with their counsel to consider the Agreement. In evaluating the Agreement, the Trustees drew on materials that they requested and which were provided to them in advance of the meeting by the Adviser and by counsel to the Fund. The materials covered, among other matters, (i) the nature, extent and quality of the services provided by the Adviser under the Agreement, (ii) the investment performance of the Fund, (iii) the costs to the Adviser of its services and the profits realized by the Adviser and its affiliates Fred Alger & Company, Incorporated and Alger Shareholder Services, Inc. from their relationship with the Fund, and (iv) the extent to which economies of scale would be realized if and as the Fund grows and whether the fee level in the Agreement reflects these economies of scale. These materials included an analysis of the Fund and the Adviser's services by Callan Associates Inc. ("Callan"), an independent consulting firm whose specialties include assistance to fund trustees and directors in their review of advisory contracts pursuant to Section 15(c) of the 1940 Act. At the meeting, senior Callan personnel provided a presentation to the Trustees based on the Callan materials. In deciding whether to renew the Agreement, the Trustees considered various factors, including those enumerated above. They also considered other direct and indirect benefits to the Adviser and its affiliates from their relationship with the Fund. NATURE, EXTENT AND QUALITY OF SERVICES In considering the nature, extent and quality of the services provided by the Adviser, the Trustees relied on their prior experience as Trustees of the Fund, their familiarity with the personnel and resources of Alger Management and its affiliates, and the materials provided at the meeting. They noted that under the Agreement the Adviser is responsible for managing the investment operations of the Fund and for providing a full range of administrative, compliance, reporting and accounting services necessary for the conduct of the Fund's affairs. The Trustees reviewed the background and experience of the Adviser's senior investment management personnel, including those individuals responsible for the investment operations of the Fund. They also considered the resources, operational structures and practices of the Adviser in managing the Fund's portfolio and administering the Fund's affairs, as well as the Adviser's overall investment management business. The Trustees concluded that the Adviser's experience, resources and strength in those areas of importance to the Fund are considerable. They noted especially the Adviser's history of expertise in managing portfolios of "growth" stocks like that of the Fund. The Trustees also considered the level and depth of the Adviser's ability to execute portfolio transactions to effect investment decisions. They also noted the history of extremely favorable reviews of the Adviser's shareholder-relations representatives by an independent rating concern. Finally, the Trustees took notice of the enhancements to the control and compliance environment at the Adviser and within the Fund. On the basis of their review, the Trustees determined that the nature and extent of the services provided to the Fund by the Adviser (including the Fund's performance, as discussed below) were of high quality and could be expected to remain so. INVESTMENT PERFORMANCE OF THE FUND Drawing upon information provided at the meeting by the Adviser as well as Callan and upon reports provided to the Trustees by the Adviser throughout the preceding year, the Trustees noted that the Fund's performance had improved substantially for the year ended August 31, 2005, beating the Fund's benchmark index by a significant margin and placing the Fund well above the median for its peer group. The Trustees acknowledged that the Adviser's recent efforts to improve the Fund's performance and, more generally, the firm's rebuilding of the investment team in response to the devastating events of September 11, 2001, were bearing fruit. Accordingly, they concluded that the performance of the Fund strongly supported renewal of the Agreement. 26 PROFITABILITY TO THE ADVISER AND ITS AFFILIATES The Trustees considered the profitability of the advisory arrangement with the Fund to the Adviser and the Adviser's affiliates and the methodology used by the Adviser in determining such profitability. The Trustees had been provided with data on the Fund's profitability to the Adviser and to the Adviser's affiliates for the Fund's most recent fiscal year. In addition, the Trustees reviewed the Fund's management fees and expense ratios and compared them with a group of comparable funds. In order to assist the Trustees in this comparison, Callan provided the Trustees with comparative information with respect to fees paid, and expense ratios incurred, by similar funds. That information indicated that the Fund's advisory fee and expense ratio were higher than the fees and expense ratios of most of the funds in the Callan reference group. The Trustees determined that this fact should be taken into account in weighing the size of the fee against the nature, extent and quality of the services provided. After discussing with representatives of the Adviser and Callan the methodologies used in computing the costs that formed the bases of the profitability calculations, they turned to the data provided. After analysis and discussion they concluded that, to the extent that the Adviser's and its affiliates' relationships with the Fund had been profitable to either or both of those entities, the profitability was not unacceptable. ECONOMIES OF SCALE On the basis of their discussions with management and their analysis of information provided at the meeting, the Trustees determined that the nature of the Fund and its operations is such that the Adviser is likely to realize economies of scale in the management of the Fund as it grows in size, but that in view of the comparatively small size of the Fund and the current level of its profitability to the Adviser, adoption of breakpoints in the advisory fee, while possibly appropriate at a later date, could await further analysis of the sources and potential scale of the economies and the fee structure that would best reflect them. Accordingly, the Trustees requested that the Adviser address this topic with the Trustees at future meetings. OTHER BENEFITS TO THE ADVISER The Trustees considered whether the Adviser benefits in other ways from its relationship with the Fund. In that connection, they noted that the Adviser maintains soft-dollar arrangements in connection with the Fund's brokerage transactions, data on which is regularly supplied to the Trustees at their quarterly meetings. The Trustees also noted that the Fund's Distributor, Fred Alger & Company, Incorporated, provides a substantial portion of the Fund's brokerage and receives shareholder servicing fees from the Fund as well, and that Alger Shareholder Services, Inc. receives fees from the Fund under a shareholder services agreement. The Trustees had been provided with information regarding, and had considered, the brokerage and shareholder servicing fee benefits in connection with their review of the profitability to the Adviser and its affiliates of their relationship with the Fund. As to the benefits received from the soft-dollar arrangements, the Trustees decided that, in light of the nature and scale of the arrangements, they were not so significant as to render the Adviser's fees excessive. CONCLUSION After weighing the foregoing factors, the Trustees, including the Independent Trustees, approved the renewal of the Investment Management Agreement. They reasoned that, considered in themselves, the services provided by the Adviser were appropriate for the needs of the Fund and of high quality, that the recent performance of the Fund had been excellent, and that the Adviser could reasonably be expected to provide services of comparable quality in the future. The Trustees determined that the fee, while higher than that charged by the majority of similar funds, was not so high as to be unreasonable when considered in relation to the nature, extent and high quality of the services currently provided, including the Fund's recent performance, that the Fund's relationship with the Adviser and its affiliates was not so profitable as to render the fee excessive, that any additional benefits to the Adviser and/or its affiliates other than those already considered in the profitability analysis were not of a magnitude materially to affect the Trustees' deliberations, and that the Fund's current size was such that the issue of sharing economies of scale with the Fund, while inviting future consideration, was not of major current importance. 27 SPECTRA FUND ADDITIONAL INFORMATION (UNAUDITED) PROXY VOTING POLICIES A description of the policies and procedures the Fund uses to determine how to vote proxies relating to portfolio securities and the proxy voting record is available, without charge, by calling (800) 711-6141 or online on the Fund's website at http://www.alger.com or on the SEC's website at http://www.sec.gov.
