Annual Report to Stockholders

December 31, 2007

Portfolio Management Review

The investments of Montgomery Street Income Securities, Inc. (the “Fund”) provided a total return based on net asset value (“NAV”) of 2.68% for the twelve-month period ended December 31, 2007.¹ The total return of the Fund, based on the market price of its New York Stock Exchange-traded shares, was –0.23% for the same period. The Fund’s total NAV return underperformed the Lehman Brothers Aggregate Bond Index, the Fund’s benchmark, which posted a total return of 6.97% for the twelve-month period.² Past results are not necessarily indicative of the future performance of the Fund. Investment return and principal value will fluctuate. The Fund paid quarterly dividends totaling $1.12 for the year ended December 31, 2007. The Fund’s market price stood at $16.13 as of December 31, 2007, compared with $17.28 as of December 31, 2006. The Fund’s shares traded at a 10.7% discount to NAV at December 31, 2007. Shares of closed-end funds frequently trade at a discount to NAV. The price of the Fund’s shares is determined by a number of factors, several of which are beyond the control of Fund management. The Fund, therefore, cannot predict whether its shares will trade at, below or above its NAV.

Although the U.S. economy grew at a solid pace for much of the year, signs of slowing emerged in the second half of 2007 as the subprime mortgage market contagion appeared to be exerting a drag on the economy. The contraction in credit and market liquidity occurring during this period led the Federal Reserve to lower the target federal funds rate on three separate occasions between September and December, bringing the rate to 4.25% at year-end. These reductions, coupled with a flight to quality, pushed Treasury yields lower, particularly on the short end, helping Treasuries to outperform all other sectors of the fixed income market.

Various factors contributed to the Fund’s underperformance versus the benchmark. An overweight to non-Treasury debt and a corresponding underweight to Treasuries was a considerable factor as Treasuries outperformed. The Fund also held an

¹ Total return based on NAV reflects changes in the Fund’s net asset value during each period. Total return based on market value reflects changes in market value. Each figure assumes that dividend and capital gains, if any, were reinvested. These figures will differ depending upon the level of any discount from or premium to NAV at which the Fund’s shares traded during the period.

² The Lehman Brothers Aggregate Bond Index is an unmanaged index representing domestic taxable investment-grade bonds, consisting of government and corporate securities, mortgage pass through securities, and asset-backed securities with average maturities of one year or more. Index returns assume reinvestment of dividends, and unlike Fund returns, do not reflect fees or expenses. It is not possible to invest directly in an index.

overweight to the financials sector, which was particularly hard hit by the credit and liquidity crunch. Financials were favored over industrials as the Fund’s investment adviser, Hartford Investment Management Company (“HIMCO”), believed the industrial sector’s significant leveraged buyout activity elevated corporate event risk levels.

In addition, the Fund held a significant position in the subprime home equity sector. A subprime borrower is one with a poor credit history that generally does not qualify to obtain conforming or conventional loans issued by agencies such as the Federal National Mortgage Association (“FNMA”) and Federal Home Loan Mortgage Corporation (“FHLMC”). Mortgages from subprime borrowers are combined, packaged and sold to investors. These packaged loans constitute the subprime market, which is also referred to as the home equity market. In 2007, lax mortgage underwriting and home appraisal standards, adjustable rate mortgages (“ARMS”) resetting at rates considerably higher than their initial teaser rates, and declining home prices led to significant deterioration in subprime obligations. HIMCO added 2.5% to this sector during the first half of the year, bringing total subprime home equity exposure in the portfolio to 3.3% at mid-year. Despite what was, at the time, a perceived inexpensive entry point, the market continued to deteriorate rapidly, fundamentally and technically, for the balance of 2007. At December 31, 2007, the Fund held subprime home equity exposure of 0.90% in the portfolio (excluding securities lending collateral).

In addition to the Fund’s holdings of packaged subprime mortgages, financial entities such as banks, brokers, and other finance companies are exposed to the subprime market directly and/or via their holdings of collateralized debt obligations (“CDOs”), structured investment vehicles (“SIVs”), and asset backed commercial paper (“ABCP”). Also affected are non-agency mortgaged backed securities other than subprime securities. While the Fund did not have direct exposure to CDOs, SIVs, or ABCP, a significant portion of Fund assets were invested in corporate bonds of finance companies and non-subprime, agency and non-agency mortgage backed securities. The Fund’s allocation to the corporate bond market was reduced by more than 10% since year-end 2006 to less than 50% of Fund assets at year-end 2007. The exposure to non-subprime mortgage backed securities was 30.4% at year-end 2007 compared to 34.0% at year-end 2006.

High yield performance and its impact on 2007 Fund results was a tale of two distinct periods. Although the high yield segment of the market performed quite well in the

first half of the year, growing risk aversion in the latter half caused yield spreads to widen dramatically, and the Fund’s exposure held back returns. In an effort to help reduce the potential impact of a supply/demand imbalance and deteriorating fundamentals within the high yield sector, HIMCO has trimmed the Fund’s below investment grade exposure to 14% at year-end versus a 28% allocation a year earlier.

The value and related income of debt securities, including mortgage-backed securities, asset-backed securities, and below-investment grade corporate bonds is sensitive to changes in economic conditions, including delinquencies and/or defaults. Recent instability in the markets for fixed-income securities, particularly mortgage-backed and asset-backed securities, has resulted in increased volatility of market prices and periods of illiquidity that have made it harder to obtain reliable market quotations for certain securities held by the Fund.

On a more positive note, the Fund’s non-dollar exposure served the Fund well, as did yield-curve positioning, which benefited from the steepening in the yield curve occurring during the year. HIMCO will look to add foreign bond exposure in the coming year as Europe and the United Kingdom lag behind the United States in their respective cycles. Both are just now starting to experience a slowdown in their respective economies, and the European Central Bank and the Bank of England have not yet embarked on aggressive easing campaigns.

Although the economy held up fairly well through year-end, supported in part by a strong employment picture, emerging signs of weakness in employment and in retail sales suggest slow growth in the months ahead. The credit crisis has clouded visibility around the economy and significantly increased the probability of recession. As a result, HIMCO believes it is likely the Federal Reserve will continue its efforts to boost liquidity, which should cause further steepening in the yield curve.

Quality Distribution (Unaudited)

* Government includes U.S. Treasury, U.S. Agency and cash.

As of December 31, 2007.

Quality distribution is subject to change.

Percentages are based on total value of the investment portfolio, excluding securities lending collateral.

The quality ratings represent the lower of Moody’s Investors Service, Inc. (“Moody’s”) or Standard & Poor’s Corporation (“S&P”) credit ratings. The ratings of Moody’s and S&P represent these companies’ opinions as to the quality of the securities they rate. Ratings are relative and subjective and are not absolute standards of quality. A bond’s credit quality does not remove the risk of an increase in interest rates or illiquidity in the market.

The views expressed in this report reflect those of the investment adviser, Hartford Investment Management Company, only through the end of the period of the report as stated on the cover. The investment adviser’s views are subject to change at any time based on market and other conditions and should not be construed as a recommendation. Investment in the Fund involves risk. The Fund invests in individual bonds whose yields and value fluctuate so that your investment may be worth more or less than its original cost. Bond investments are subject to interest rate risk such that when interest rates rise, the price of the bonds, and thus the value of the Fund, can decline and the investor can lose principal value. The Fund’s investments are also subject to credit risk and liquidity risk. Additionally, investing in foreign securities presents certain unique risks not associated with domestic investments, such as currency fluctuation, political and economic changes, and market risks. All of these factors may result in greater share price volatility. Closed-end funds, unlike open-end funds, are not continuously offered.

Other Information

Dividends Paid

The Fund paid dividends of $0.29 per share on April 30, 2007 (including approximately $0.01 of previously undistributed income); $0.28 per share on July 31, 2007; $0.27 per share on October 31, 2007; and $0.28 per share on December 31, 2007. In the near term, dividends to be paid by the Fund may be negatively impacted by recent declines in overall interest rates and the current reduction in the Fund’s allocation to high yield securities.

Dividend Reinvestment and Cash Purchase Option

The Fund maintains an optional Dividend Reinvestment and Cash Purchase Plan (the “Plan”) for the automatic reinvestment of your dividends and capital gain distributions in the shares of the Fund. Stockholders who participate in the Plan also can purchase additional shares of the Fund through the Plan’s voluntary cash investment feature. We recommend that you consider enrolling in the Plan to build your investment. The Plan’s features, including the voluntary cash investment feature, are described beginning on page 35 of this report.

Limited Share Repurchases

The Fund is authorized to repurchase a limited number of shares of the Fund’s common stock from time to time when the shares are trading at less than 95% of their NAV. Repurchases are limited to a number of shares each calendar quarter approximately equal to the number of new shares issued under the Plan with respect to income earned for the second preceding calendar quarter. There were 12,000 shares repurchased during each quarter of 2007. Up to 11,000 shares may be repurchased during the first quarter of 2008.

Investment Objectives and Policies

Investment Objectives

Your Fund is a closed-end diversified management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”), investing and reinvesting its assets in a portfolio of selected securities. The Fund’s primary investment objective is to seek as high a level of current income as is consistent with prudent investment risks, from a diversified portfolio primarily of debt securities. Capital appreciation is a secondary objective.

Principal Investment Policies

Investment of your Fund is guided by the principal investment policies summarized below. For a more complete description of the Fund’s investment policies, please see the Fund’s Form N-2 Registration Statement dated April 29, 1992 and subsequent annual reports to stockholders.

Under normal circumstances, the Fund will invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in income producing securities.¹

At least 70% of total assets must be invested in: straight debt securities (other than municipal securities), including U.S. dollar-denominated debt securities of foreign issuers, rated within the four highest grades assigned by Moody’s Investors Service, Inc. or Standard & Poor’s Corporation; bank debt of comparable quality; U.S. government or agency securities; commercial paper; cash; cash equivalents; or Canadian government, provincial, or municipal securities (not in excess of 25% of total assets).

Up to 30% of total assets (the “30% basket”) may be invested in other U.S. or foreign straight debt securities; convertible securities; and preferred stocks.

Not more than 25% of total assets may be invested in securities of any one industry (finance companies as a whole are not considered an “industry” for the purposes of this limitation).

Not more than 5% of total assets may be invested in securities of any one issuer, other than U.S. government or agency securities.

¹ The Fund will provide stockholders with at least 60 days’ notice prior to making any changes to this 80% investment policy.

Montgomery Street Income Securities, Inc. 9

The Fund may invest money pursuant to repurchase agreements so long as the Fund is initially wholly secured with collateral consisting of securities in which the Fund can invest under its investment objectives and policies. In addition, investments in repurchase agreements must not, at the time of any such loan, be as a whole more than 20% — and be as to any one borrower more than 5% — of the Fund’s total assets.

The Fund may lend its portfolio securities to the extent permitted under the 1940 Act.

The Fund may borrow funds to purchase securities, provided that the aggregate amount of such borrowings may not exceed 30% of the Fund’s assets (including aggregate borrowings), less liabilities (excluding such borrowings).

The Fund may enter into forward foreign currency sale contracts to hedge portfolio positions, provided, among other things, that such contracts have a maturity of one year or less and that, at the time of purchase, the Fund’s obligations under such contracts do not exceed either the value of portfolio securities denominated in the foreign currency or 15% of the Fund’s total assets.

The Fund may enter into interest rate futures contracts and purchase or write options on interest rate futures contracts, provided, among other things, that the Fund’s obligations under such instruments may not exceed the value of the Fund’s assets not subject to the 30% basket.

It is the intention of the Fund to invest exclusively in non-voting securities. Under normal circumstances, the Fund does not intend to exercise conversion, exchange or other rights to purchase common stock or other equity securities, or otherwise to hold voting securities. In the unlikely event that the Fund does come into possession of any voting securities, the Fund intends to dispose of such securities as soon as it is reasonably practicable and prudent to do so.

Notes to Financial Statements

A. Significant Accounting Policies

The Fund is registered under the 1940 Act, as a closed-end, diversified management investment company.

The Fund’s financial statements are prepared in accordance with accounting principles generally accepted in the United States of America which require the use of management estimates. Actual results could differ from those estimates. The policies described below are followed consistently by the Fund in the preparation of its financial statements.

Security Valuation. Investments are stated at value determined as of the close of regular trading (generally, 4:00 PM Eastern Time) on the New York Stock Exchange on each day the exchange is open for trading. Debt securities are valued by independent pricing services approved by, or at the direction of, the Board of Directors of the Fund. Such services may use various pricing techniques which take into account appropriate factors such as yield, quality, coupon rate, maturity, type of issue, trading characteristics and other data, as well as broker quotes. If the pricing services are unable to provide valuations, the securities are valued at the most recent bid quotation or evaluated price, as applicable, obtained from a broker/dealer. Fixed income securities with a remaining maturity of sixty days or less, maturing at par, are valued at amortized cost. Securities and other assets for which market quotations are not readily available or for which the above valuation procedures are deemed not to reflect fair value are valued in a manner that is intended to reflect their fair value as determined in accordance with procedures approved by the Board of Directors.

Security Transactions and Investment Income. Investment transactions are accounted for on a trade date plus one basis for daily net asset value calculations. However, for financial reporting purposes, investment transactions are reported on trade date. Interest income is recorded on the accrual basis. All premiums and discounts are amortized/accreted for financial reporting purposes. Dividend income is recorded on the ex-dividend date.

Foreign Currency Translations. The accounting records of the Fund are maintained in U.S. dollars. Investment securities and other assets and liabilities denominated in a foreign currency are translated into U.S. dollars generally using exchange rates in effect as of 4:00 PM Eastern Time. Purchases and sales of investment securities, income receipts, and expense payments are translated into U.S. dollars at the exchange rates prevailing on the respective dates of such transactions. The Fund does not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of foreign securities. Such fluctuations are included in net realized gain (loss) on investments and net change in unrealized appreciation (depreciation) on investments, respectively.

Montgomery Street Income Securities, Inc. 27

Net realized gains and losses on foreign currency related items are considered ordinary income for tax purposes and arise from sales of foreign currencies, currency gains or losses realized between the trade and settlement dates on securities transactions, the difference between the amounts of dividends, interest, and foreign withholding taxes recorded and the U.S. dollar equivalent of the amounts actually received or paid, and the realized gains or losses resulting from portfolio and transaction hedges. Net change in unrealized appreciation (depreciation) on foreign currency related items arises from changes in the fair value of assets and liabilities, other than investments in securities, at period end resulting from changes in exchange rates.

Repurchase Agreements. The Fund may enter into repurchase agreements with certain banks and broker/dealers whereby the Fund agrees to purchase a security with a simultaneous agreement by the seller to repurchase the security back from the Fund at a specified price and date or upon demand. The Fund, through its custodian bank or sub-custodian bank, receives delivery of the underlying securities as collateral, the amount of which at the time of purchase and each subsequent business day is required to be maintained at such a level that the collateral’s value is at least equal to the principal amount of the repurchase price plus accrued interest. The custodian or agent bank holds the collateral in a separate account until the agreement matures. If the counterparty defaults and the value of the collateral declines or if bankruptcy proceedings are commenced with respect to the counterparty, realization of the collateral by the Fund may be delayed or limited. There were no repurchase agreements outstanding at December 31, 2007.

When-Issued/Delayed Delivery Securities. The Fund may purchase securities with delivery or payment to occur at a later date beyond the normal settlement period. At the time the Fund enters into a commitment to purchase a security, the transaction is recorded and the value of the security is reflected in the net asset value. The price of such security and the date when the security will be delivered and paid for are fixed at the time the transaction is negotiated. The value of the security may vary with market fluctuations. No interest accrues to the Fund until settlement of the trade. Certain risks may arise upon entering into when-issued or delayed delivery securities from the potential inability of counterparties to meet the terms of their contracts or if the issuer does not issue the securities due to political, economic, or other factors. Additionally, losses may arise due to changes in the value of the underlying securities.

Securities Lending. The Fund has entered into a securities lending arrangement with its custodian. Under the terms of the agreement, the Fund receives a fee equal to a percentage of the net income generated by the collateral held during each lending transaction. The custodian is authorized to loan securities on behalf of the Fund to approved borrowers and is required to maintain collateral at least equal in value to

28 Montgomery Street Income Securities, Inc.

the value of the securities loaned. Cash collateral is invested by the custodian in the Mellon GSL Delaware Business Trust Collateral Fund (a pooled investment fund). In the event of bankruptcy or other default of the borrower, the Fund could experience delays in liquidating the loan collateral or recovering the loaned securities and incur expenses related to enforcing its rights. In addition, there could be a decline in the value of the collateral or in the fair value of the securities loaned while the Fund seeks to enforce its rights thereto and the Fund could experience subnormal levels of income or lack of access to income during that period. The Fund bears the risk of any deficiency in the amount of collateral available for return to a borrower due to a loss in an approved investment.

Loan Participations/Assignments. The Fund may invest in U.S. dollar denominated fixed and floating rate loans arranged through private negotiations between a foreign sovereign entity and one or more financial institutions (“Lenders”). The Fund invests in such loans in the form of participations in loans or assignments of all or a portion of loans from third parties. Participations typically result in the Fund having a contractual relationship only with the Lender, not with the sovereign borrower. The Fund has the right to receive payments of principal, interest and any fees to which it is entitled from the Lender selling the participation and only upon receipt by the Lender of the payments from the borrower. In connection with purchasing participations, the Fund generally has no right to enforce compliance by the borrower with the terms of the loan agreement relating to the Loan, nor any rights of set-off against the borrower, and the Fund will not benefit directly from any collateral supporting the Loan in which it has purchased the participation. As a result, the Fund assumes the credit risk of both the borrower and the Lender that is selling the participation. At December 31, 2007, the Fund held no participations.

Federal Income Taxes. The Fund intends to qualify as a “regulated investment company” and to distribute substantially all net investment income and net capital gains, if any, to its stockholders and otherwise comply with Subchapter M of the Internal Revenue Code applicable to regulated investment companies. Therefore, no federal income tax provision is required.

Recent Accounting Pronouncements. On July 13, 2006, the Financial Accounting Standards Board (“FASB”) released FASB Interpretation No. 48 “Accounting for Uncertainty in Income Taxes” (“FIN 48”). FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Fund’s tax returns to determine whether the tax positions are “more-likely-than-not” of being sustained by the applicable tax authority. Tax positions not deemed to meet the “more-likely-than-not” threshold would be recorded as an expense in the current year. FIN 48 requires

Montgomery Street Income Securities, Inc. 29

that management evaluate the tax positions taken in returns that remain subject to examination by the Fund’s major tax jurisdictions. At December 31, 2007, returns subject to examination include those filed for the period ended December 31, 2004 and thereafter. Management adopted FIN 48 in 2007 and has evaluated the Fund’s tax positions for the applicable periods. Based on that evaluation, management concluded that the adoption of FIN 48 did not have an effect on the Fund’s financial statements.

In September 2006, the FASB issued Statement on Financial Accounting Standards No. 157, “Fair Value Measurements” (“SFAS No. 157”). This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007. The changes to current generally accepted accounting principles from the application of this Statement relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. Management has analyzed the impact of SFAS No. 157 and does not believe the adoption of SFAS No. 157 will impact the financial statement amounts, however, additional disclosures may be required about the inputs used to develop the measurements and the effect of certain of the measurements on changes in net assets for future periods.

Distribution of Income and Capital Gains. The amount and timing of distributions are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States of America. Distributions of net investment income are paid quarterly. Net realized gains from investment transactions will be distributed to stockholders at least annually to the extent they exceed available capital loss carryforwards. The Fund uses the specific identification method for determining realized gain or loss on investments sold for both financial and federal income tax reporting purposes.

Contingencies. In the normal course of business, the Fund may enter into contracts with service providers that contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Fund that have not yet been made. However, based on experience to date, the Fund expects any risk of loss to be remote.

Forward Foreign Currency Contracts. The Fund may enter into forward foreign currency contracts, generally to hedge foreign currency exposure between trade date and settlement date on security purchases and sales or to minimize foreign currency risk on portfolio securities denominated in foreign currencies. All contracts are marked-to-market daily based on the forward currency exchange rate. The change in

30 Montgomery Street Income Securities, Inc.

value is recorded as a receivable or payable from forward currency contracts. When a contract is closed, the difference between the value of the contract at the time it was opened and the value at the time it was closed is recorded as net realized gain (loss) on foreign currency related items. The use of forward foreign currency contracts does not eliminate fluctuations in the underlying prices of the Fund’s portfolio securities, but it does establish a rate of exchange that can be achieved in the future. These contracts involve market risk in excess of the receivable or payable related to forward foreign currency contracts reflected in the Statement of Assets and Liabilities. Although contracts limit the risk of loss due to a decline in the value of the hedged currency, they also limit any potential gain that might result should the value of the currency increase. Additionally, the Fund could be exposed to the risk of a previously hedged position becoming unhedged if the counterparty to a contract is unable to meet the terms of the contract.

Futures Contracts. The Fund may buy and sell futures contracts to manage its exposure to changes in securities prices and foreign currencies or as an efficient means of adjusting overall exposure to certain markets. The risks associated with the use of futures contracts include the possibility that the value of the futures contract may not correlate with the change in the value of the hedged instrument. In addition, there is the risk that the Fund may not be able to enter into a closing transaction because of an illiquid market. Upon entering into a futures contract, the Fund is required to deposit with the broker an amount of cash or cash equivalents equal to a certain percentage of the contract amount. This is known as the “initial margin.” Futures contracts are valued based upon their quoted daily settlement prices. In the event that the settlement price is unavailable, the closing price will be used for valuation. The Fund receives from or pays to the counterparty an amount of cash equal to the daily fluctuation in the value of the contracts. Such receipts or payments, known as the "variation margin," are recorded by the Fund until the contracts are terminated at which time a realized gain or loss is recognized. Futures contracts involve, to varying degrees, risk of loss in excess of the variation margin reflected in the Statement of Assets and Liabilities.

B. Purchases and Sales of Securities

During the year ended December 31, 2007, purchases and sales of investment securities, excluding U.S. government obligations and short-term investments, aggregated $98,455,394 and $118,039,983, respectively. Purchases and sales of long-term U.S. government obligations aggregated $128,146,998 and $104,181,826, respectively.

C. Related Parties

Investment Advisory Agreement. The Fund and HIMCO entered into an Investment Advisory Agreement whereby the Fund pays HIMCO a quarterly fee

Montgomery Street Income Securities, Inc. 31

equal to the product of (a) one quarter of 0.25%, times (b) the average of the net assets of the Fund on the last business day of each calendar month of the then ended calendar quarter.

Fund Accounting and Administration Services Agreement. The Fund has entered into a Fund Accounting and Administration Services Agreement (“Administration Agreement”) with Jackson Fund Services (“JFS”). Pursuant to the Administration Agreement, the Fund pays JFS an annual fee, payable monthly, equal to 0.25% of the value of the net assets of the Fund up to $100 million; 0.20% of the value of the net assets of the Fund from $100 million to $200 million; and 0.15% of the value of the net assets of the Fund over $200 million. JFS makes individuals available to the Fund to serve as its officers, without compensation from the Fund.

Directors’ Fees and Expenses. The Fund pays each Director a retainer fee plus specified amounts for each Board and Committee meeting attended.

D. Federal Income Tax Matters

The following information is presented on an income tax basis. The timing and characterization of certain income and capital gains distributions are determined in accordance with federal tax regulations, which may differ from accounting principles generally accepted in the United States of America. These differences primarily relate to timing differences in recognizing premium amortization on debt securities and timing differences in recognizing certain gains and losses on investment transactions. To the extent that differences arise that are permanent in nature, such amounts are reclassified within the components of net assets on the Statement of Assets and Liabilities based on their federal income tax treatment; timing differences do not require reclassification. Timing and permanent differences do not impact the net asset values of the Fund. In 2007, the permanent differences increased undistributed net investment income and accumulated realized loss by $1,040,694.

At December 31, 2007, the components of net unrealized depreciation and cost of investments are listed in the following table.

Cost of Investments	Gross Unrealized Depreciation	Gross Unrealized Appreciation	Net Unrealized Depreciation
$234,155,566	$(9,020,631)	$598,274	$(8,422,357)

At December 31, 2007, the Fund had undistributed net ordinary income of $518,874.

The distributions paid of $11,620,203 and $10,892,738 for the years ended December 31, 2007 and 2006, respectively, were from net ordinary income.

32 Montgomery Street Income Securities, Inc.

At December 31, 2007, the Fund had unused capital loss carryforwards available for federal income tax purposes which may be applied against any future realized net taxable capital gains or until the respective expiration dates occur as noted below.

Amount	Year of Expiration
$   781,347	2010
1,872,360	2013
3,952,947	2014
596,899	2015
Total: $7,203,553

E. Share Repurchases

The Fund is authorized to effect periodic repurchases of its shares in the open market from time to time when the Fund’s shares trade at a discount to their net asset value. During the year ended December 31, 2007, the Fund purchased 48,000 shares of common stock on the open market at a total cost of $812,304. The weighted average discount of these purchases, comparing the purchase price to the net asset value at the time of purchase was 9.5%. During the year ended December 31, 2006, the Fund purchased 46,000 shares of common stock on the open market at a total cost of $783,964 with a weighted average discount of 9.7%.

Report of Independent Registered Public

Accounting Firm

To the Shareholders and Board of Directors of

Montgomery Street Income Securities, Inc.:

We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Montgomery Street Income Securities, Inc. (the “Fund”), as of December 31, 2007, and the related statement of operations for the year then ended and the statement of changes in net assets and financial highlights for each of the two 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 audit. The financial highlights of the Fund for each of the periods ended on or prior to December 31, 2005, were audited by other auditors whose report, dated February 22, 2006, 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. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit 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, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2007, by correspondence with the Fund’s custodian. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of the Fund as of December 31, 2007, and the results of its operations for the year then ended, and the changes in its net assets and the financial highlights for the two years then ended in conformity with accounting principles generally accepted in the United States of America.

Dividend Reinvestment and Cash Purchase Plan

All registered stockholders of the Fund’s Common Stock are offered the opportunity of participating in the Plan. Registered stockholders, on request or on becoming registered stockholders, are mailed information regarding the Plan, including a form by which they may elect to participate in the Plan and thereby cause their future net investment income dividends and capital gains distributions to be invested in shares of the Fund’s common stock. Mellon Bank, N.A. is the agent (the “Plan Agent”) for stockholders who elect to participate in the Plan.

If a stockholder chooses to participate in the Plan, the stockholder’s dividends and capital gains distributions will be promptly invested, automatically increasing the stockholder’s holdings in the Fund. If the Fund declares a dividend or capital gains distributions payable either in cash or in stock of the Fund, the stockholder will automatically receive stock. If the market price per share on the payment date for the dividend (the “Valuation Date”) equals or exceeds the net asset value per share, the Fund will issue new shares to the stockholder at the greater of the following on the Valuation Date: (a) net asset value per share or (b) 95% of the market price per share. If the market price per share on the Valuation Date is less than the net asset value per share, the Fund will issue new shares to the stockholder at the market price per share on the Valuation Date. In either case, for federal income tax purposes the stockholder will be deemed to receive a distribution equal to the market value on the Valuation Date of the new shares issued. If dividends or capital gains distributions are payable only in cash, then the stockholder will receive shares purchased on the New York Stock Exchange or otherwise on the open market. In this event, for federal income tax purposes the amount of the distribution will equal the cash distribution paid. State and local taxes may also apply. All reinvestments are in full and fractional shares, carried to three decimal places.

Stockholders participating in the Plan can also purchase additional shares quarterly in any amount from $100 to $5,000 (a “Voluntary Cash Investment”) by sending in a check together with the cash remittance slip, which will be sent with each statement of the stockholder’s account, to Mellon Investor Services LLC, the Fund’s transfer agent (the “Transfer Agent”). Such additional shares will be purchased on the open market by the Plan Agent or its delegate. The purchase price of shares purchased on the open market, whether pursuant to a reinvestment of dividends payable only in cash or a

Montgomery Street Income Securities, Inc. 35

Voluntary Cash Investment, will be the average price (including brokerage commissions) of all shares purchased by the Plan Agent or its delegate on the date such purchases are effected. In addition, stockholders may be charged a service fee in an amount up to 5% of the value of the Voluntary Cash Investment. Although subject to change, stockholders are currently charged $1 for each Voluntary Cash Investment.

Stockholders may terminate their participation in the Plan at any time and elect to receive dividends and other distributions in cash by notifying the Transfer Agent in writing. Such notification must be received not less than 10 days prior to the record date of any distribution. There is no charge or other penalty for such termination. The Plan may be terminated by the Fund upon written notice mailed to the stockholders at least 30 days prior to the record date of any distribution. Upon termination, the Fund will issue certificates for all full shares held under the Plan and cash for any fractional share.

Alternatively, stockholders may request the Transfer Agent to instruct the Plan Agent or its delegate to sell any full shares and remit the proceeds, less a $2.50 service fee and less brokerage commissions. The sale of shares (including fractional shares) will be a taxable event for federal income tax purposes and may be taxable for state and local tax purposes.

The Plan may be amended by the Fund at any time. Except when required by law, written notice of any amendment will be mailed to stockholders at least 30 days prior to its effective date. The amendment will be deemed accepted unless written notice of termination is received by the Transfer Agent prior to the effective date.

An investor holding shares in its own name can participate directly in the Plan. An investor holding shares in the name of a brokerage firm, bank or other nominee should contact that nominee, or any successor nominee, to determine whether the nominee can participate in the Plan on the investor’s behalf and to make any necessary arrangements for such participation.

Additional information, including a copy of the Plan and its Terms and Conditions and an enrollment form, can be obtained from the Transfer Agent by writing Mellon Investor Services LLC, P.O. Box 3315, South Hackensack, NJ 07606-1915, or by calling (877) 437-3938.

Item 2. Code of Ethics.

As of December 31, 2007, the registrant had adopted a “code of ethics” (as such term is defined in the instructions to Item 2 of Form N-CSR) that applies to the registrant’s principal executive officer and principal financial and accounting officer. This code is filed as Exhibit 12(a)(1) hereto. There were no substantive amendments or waivers to the code of ethics during the period covered by this report.

Item 3. Audit Committee Financial Expert.

The registrant’s Board of Directors has determined that Mr. John T. Packard, Mr. Wendell G. Van Auken, and Mr. James C. Van Horne are “audit committee financial experts” (as such term is defined in the instructions to Item 3 of Form N-CSR). Each of these individuals is “independent,” meaning that he is not an “interested person” of the registrant (as that term is defined in Section 2(a)(19) of the Investment Company Act of 1940, as amended) and he does not accept any consulting, advisory, or other compensatory fee from the registrant (except in his capacity as a Board or committee member).

An “audit committee financial expert” is not an “expert” for any purpose, including for purposes of Section 11 of the Securities Act of 1933, as amended, as a result of being designated as an “audit committee financial expert.” Further, the designation of a person as an “audit committee financial expert” does not mean that the person has any greater duties, obligations, or liability than those imposed on the person without the “audit committee financial expert” designation. Similarly, the designation of a person as an “audit committee financial expert” does not affect the duties, obligations, or liability of any other member of the Audit Committee or Board of Directors.

Item 4. Principal Accountant Fees and Services.

(a) – (d)

Deloitte & Touche LLP (“Deloitte”) was appointed by the Board of Directors as the independent registered public accounting firm of the registrant for the fiscal years ended December 31, 2006 and December 31, 2007.

The following table sets forth the amount of fees that were billed by the principal accountant for the respective period to the registrant.

Fees for Services Rendered to the Registrant by the Principal Accountant

Fiscal Year	Audit Fees	Audit-Related Fees	Tax Fees	All Other Fees
2006	$43,000	$0	$6,000	$0
2007	$44,800	$0	$4,000	$0

Tax Fees for 2006 and 2007 represent fees for services rendered to the registrant for tax return preparation and review of income and capital gains distributions.

Effective as of the close of business on June 9, 2006, Hartford Investment Management Company (“HIMCO”) became the investment adviser of the registrant.

The following table sets forth the amount of fees that were billed by the principal accountant for the respective period to any entity controlling, controlled by or under common control with HIMCO that provided ongoing services to the registrant (“Adviser Entities”) that were directly related to the registrant’s operations and financial reporting.

Fees for Services Rendered to Adviser Entities by the Principal Accountant

Fiscal Year	Audit-Related Fees	Tax Fees	All Other Fees
2006	$62,552	$0	$0
2007	$62,859	$0	$0

Audit Related Fees for 2006 and 2007 included fees for an attestation engagement relating to HIMCO’s performance presentations.

(e)(1) The Audit Committee has adopted procedures for the pre-approval by the Audit Committee of the engagement of the registrant’s independent auditors to provide audit and non-audit services to the registrant and the engagement of the registrant’s independent auditors to provide non-audit services to the registrant’s investment adviser or its related entities that related directly to the registrant’s operations and financial reporting. If time does not permit, the Chairman of the Audit Committee is authorized to pre-approve the engagement of the independent auditors on behalf of the Audit Committee. The independent auditors and the investment adviser are required to report on the initiation of any such engagement at the next regular Audit Committee meeting.

(e)(2) Not applicable.

(f) Not applicable.

(g) The aggregate amount of non-audit fees billed by the principal accountant to the registrant and Adviser Entities was $68,552 for 2006, and is detailed in the table above. The aggregate amount of non-audit fees billed by the principal accountant to the registrant and Adviser Entities was $66,859 for 2007, and is detailed in the table above.

(h) For the fiscal years ended December 31, 2006 and December 31, 2007, the Audit Committee of the registrant’s Board of Directors considered the provision of non-audit services that were rendered to the respective Adviser Entities that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X and

concluded that such services were compatible with maintaining the respective principal accountant’s independence.

Item 5. Audit Committee of Listed Registrants.

(a) The registrant has a separately-designated standing audit committee established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934, as amended. The registrant's audit committee consists of Wendell G. Van Auken (Chairman), John T. Packard, and James C. Van Horne.

(b) Not applicable.

Item 6. Schedule of Investments.

Included in Reports to Stockholders under Item 1.

Item 7. Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment Companies.

It is the intention of the registrant to invest exclusively in non-voting securities. Under normal circumstances, the registrant does not intend to exercise conversion, exchange or other rights to purchase common stock or other equity securities, or otherwise to hold voting securities. In the unlikely event that the registrant does come into possession of any voting securities, the registrant intends to dispose of such securities as soon as it is reasonably practicable and prudent to do so.

Item 8. Portfolio Managers of Closed-End Management Investment Companies.

Portfolio managers, including assistant portfolio managers, at Hartford manage multiple portfolios for multiple clients. These accounts may include mutual funds, separate accounts (assets managed on behalf of institutions such as pension funds, insurance companies, foundations), commingled trust accounts, and other types of funds. The portfolios managed by a portfolio manager may have investment objectives, strategies and risk profiles that differ from those of the registrant. Portfolio managers make investment decisions for each portfolio, including the registrant, based on the investment objectives, policies, practices and other relevant investment considerations applicable to that portfolio. Consequently, the portfolio managers may purchase securities for one portfolio and not another portfolio. Securities purchased in one portfolio may perform better than the securities purchased for another portfolio, and vice versa. A portfolio manager or other investment professionals at Hartford may place

transactions on behalf of other accounts that are directly or indirectly contrary to investment decisions made on behalf of the registrant, or make investment decisions that are similar to those made for the registrant, both of which have the potential to adversely impact the registrant depending on market conditions. In addition, some of these portfolios have fee structures that are or have the potential to be higher, in some cases significantly higher, than the fees paid by the registrant. Because a portfolio manager’s compensation is affected by revenues earned by Hartford, the incentives associated with the registrant may be significantly higher or lower than those associated with other accounts managed by a given portfolio manager.

Hartford’s goal is to provide high quality investment services to all of its clients, while meeting its fiduciary obligation to treat all clients fairly. Hartford has adopted and implemented policies and procedures, including brokerage and trade allocation policies and procedures, that it believes address the conflicts associated with managing multiple accounts for multiple clients. In addition, Hartford monitors a variety of areas, including compliance with applicable laws and regulations, primary guidelines of the registrant, the allocation of securities, and compliance with Hartford’s Code of Ethics. Furthermore, senior investment and business personnel at Hartford periodically review the performance of Hartford’s portfolio managers. Although the firm does not track the time a portfolio manager spends on a single portfolio, it does periodically assess whether a portfolio manager has adequate time and resources to effectively manage the portfolio manager’s overall book of business.

Material conflicts of interest may arise when allocating and/or aggregating trades. Hartford may aggregate into a single trade order several individual contemporaneous client trade orders for a single security, absent specific client directions to the contrary. It is the policy of Hartford that when a decision is made to aggregate transactions on behalf of more than one account (including the registrant or other accounts over which it has discretionary authority), such transactions will be allocated to all participating client accounts in a fair and equitable manner in accordance with Hartford’s trade allocation policy. The trade allocation policy is described in Hartford’s Form ADV. Hartford’s compliance unit monitors block transactions to assure adherence to the trade allocation policy, and will inform Hartford’s Issue Resolution Council of any non-compliant transactions.

The conflicts addressed in the foregoing paragraph are primarily dealt with through strict adherence to Hartford’s Trade Allocation Policy.

As of December 31, 2007, the compensation package for portfolio managers consists of three components, which are base pay, annual incentive and long-term incentive. The base pay program provides a level of base pay that is competitive with the marketplace and reflects a portfolio manager’s contribution to Hartford’s success.

The annual incentive plan provides cash bonuses dependent on both the overall performance of Hartford and individual contributions. A portion of the bonus pool is determined based on the aggregate portfolio pre-tax performance results over three years relative to peer groups and benchmarks, and the remaining portion is based on current year operating income relative to the operating plan.

Bonuses for portfolio managers vary depending on the scope of accountability and experience level of the individual portfolio manager. An individual’s award is based on qualitative and quantitative factors including the relative performance of his/her assigned portfolios compared to a peer group or benchmark and is primarily geared to reward top quartile performance on a trailing three-year basis. The registrant is a member of the Lipper Corporate Debt Funds BBB-Rated Category and is benchmarked to the Lehman Brothers Aggregate Bond Index. Qualitative factors such as leadership, teamwork and overall contribution made during the year are also considered.

The long-term incentive plan provides an opportunity for portfolio managers and other key contributors to Hartford to be rewarded in the future based on the continued profitable growth of Hartford. A designated portion of the Hartford’s net operating income will be allocated to long-term incentive awards each year. The size of the actual individual awards will vary greatly. The awards will vest over three years for most participants and five years for Hartford’s Managing Directors. The value of the awards will increase at the growth rate of operating income each year during the vesting period. Awards will be paid in cash at the end of the vesting period.

All portfolio managers are eligible to participate in The Hartford Financial Services Group, Inc.'s standard employee health and welfare programs, including retirement.

As of December 31, 2007, the registrant’s portfolio managers owned the following equity securities of the registrant:

Portfolio Manager	Dollar Range of Equity Securities Beneficially Owned as of December 31, 2007

Exhibit 12(a)(1)

MONTGOMERY STREET INCOME SECURITIES, INC.

(“Fund”)

PRINCIPAL EXECUTIVE AND PRINCIPAL FINANCIAL OFFICER

CODE OF ETHICS

I. Overview

This Principal Executive Officer and Principal Financial Officer Code of Ethics ("Officer Code") sets forth the policies, practices, and values expected to be exhibited in the conduct of the Principal Executive Officer and Principal Financial Officer (“Covered Officers”) of the Fund. A list of the Fund’s Covered Officers is included on Appendix A.

The Board of Directors of the Fund has elected to implement the Officer Code, pursuant to Section 406 of the Sarbanes-Oxley Act of 2002 and the U.S. Securities and Exchange Commission’s (“SEC's”) rules thereunder, to promote and demonstrate honest and ethical conduct in its Covered Officers.

The Covered Officers also are employees of the Fund’s administrator, Jackson Fund Services (“JFS”), a division of Jackson National Asset Management, LLC (“JNAM”). Thus, in addition to adhering to the Officer Code, these individuals must comply with JNAM’s Code of Ethics, as adopted pursuant to Rule 17j-1 under the Investment Company Act of 1940, as amended.¹ In addition, such individuals also must comply with other applicable Fund policies and procedures.

JFS and the Covered Officers provide administrative and pricing services to the Fund. JFS and the Covered Officers do not have investment management decision-making authority for the Fund. Hartford Investment Management Company serves as the investment adviser to the Fund. In addition, JFS and the Covered Officers are not engaged in the distribution of Fund shares.

The Fund’s Chief Compliance Officer (“CCO”), who shall not be a Covered Officer and who shall serve as such subject to the approval of the Fund’s Board (or committee thereof), is primarily responsible for implementing and enforcing this Code. The CCO has the authority to interpret this Officer Code and its applicability to particular circumstances. Any questions about the Officer Code should be directed to the CCO.

The CCO and his or her contact information can be found in Appendix A.

_________________________

¹ The obligations imposed by the Officer Code are separate from, and in addition to, any obligations imposed under codes of ethics adopted pursuant to Rule 17j-1 under the Investment Company Act of 1940, and any other code of conduct applicable to Covered Officers in whatever capacity they serve. The Officer Code does not incorporate any of those other codes and, accordingly, violations of those codes will not necessarily be considered violations of the Officer Code and waivers granted under those codes would not necessarily require a waiver to be granted under this Code. Sanctions imposed under those codes may be considered in determining appropriate sanctions for any violation of this Code.

1

II. Purposes of the Officer Code

The purposes of the Officer Code are to deter wrongdoing and to:

• promote honest and ethical conduct among Covered Officers, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships;

• promote full, fair, accurate, timely and understandable disclosures in reports and documents that the Fund files with or submits to the SEC (and in other public communications from the Fund) and that are within the Covered Officer's responsibilities;

• promote compliance with applicable laws, rules and regulations;

o encourage the prompt internal reporting of violations of the Officer Code to the CCO; and

o establish accountability for adherence to the Officer Code.

Any questions about the Officer Code should be referred to the CCO.

III. Responsibilities of Covered Officers

A. Honest and Ethical Conduct

It is the duty of every Covered Officer to encourage and demonstrate honest and ethical conduct, as well as adhere to and require adherence to the Officer Code and any other applicable policies and procedures designed to promote this behavior. Covered Officers must at all times conduct themselves with integrity and distinction, putting first the interests of the Fund. Covered Officers must be honest and candid while maintaining confidentiality of information where required by law or Fund policy.

Covered Officers also must, at all times, act in good faith, responsibly and with due care, competence and diligence, without misrepresenting or being misleading about material facts or allowing their independent judgment to be subordinated. Covered Officers also should maintain skills appropriate and necessary for the performance of their duties for the Fund. Covered Officers also must responsibly use and control all Fund assets and resources entrusted to them.

Covered Officers may not retaliate against others for, or otherwise discourage the reporting of, actual or apparent violations of the Officer Code or applicable laws or regulations. Covered Officers should create an environment that encourages the exchange of information, including concerns of the type that this Code is designed to address.

B. Conflicts of Interest

A "conflict of interest" occurs when a Covered Officer's personal interests interfere with the interests of the Fund for which he or she serves as an officer. Covered Officers may not

2

improperly use their position with a Fund for personal or private gain to themselves, their family, or any other person. Similarly, Covered Officers may not use their personal influence or personal relationships to influence decisions or other Fund business or operational matters where they would benefit personally at the Fund's expense or to the Fund's detriment. Covered Officers may not cause the Fund to take action, or refrain from taking action, for their personal benefit at the Fund's expense or to the Fund's detriment.

Certain conflicts of interest covered by this Code arise out of the relationships between Covered Officers and the Fund that already are subject to conflict of interest provisions in the Investment Company Act and the Investment Advisers Act. For example, Covered Officers may not individually engage in certain transactions (such as the purchase or sale of securities or other property) with the Fund because of their status as "affiliated persons" of the Fund. Covered Officers must comply with applicable laws and regulations. Therefore, any violations of existing statutory and regulatory prohibitions on individual behavior could be considered a violation of this Code.

As to conflicts arising from or as a result of the relationship between the Fund and Jackson Fund Services, of which the Covered Officers are also officers or employees, it is recognized by the Board that, subject to Jackson Fund Services' fiduciary duties to the Fund, the Covered Officers will in the normal course of their duties (whether formally for the Fund or for Jackson Fund Services, or for both) be involved in establishing policies and implementing decisions which will have different effects on Jackson Fund Services and the Fund. The Board recognizes that the participation of the Covered Officers in such activities is inherent in the contract relationship between the Fund and Jackson Fund Services, and is consistent with the expectation of the Board of the performance by the Covered Officers of their duties as officers of the Fund.

Covered Officers should avoid actual conflicts of interest, and appearances of conflicts of interest, between the Covered Officer's duties to the Fund and his or her personal interests beyond those contemplated or anticipated by applicable regulatory schemes. If a Covered Officer suspects or knows of a conflict or an appearance of one, the Covered Officer must immediately report the matter to the CCO. If a Covered Officer, in lieu of reporting such a matter to the CCO, may report the matter directly to the Fund's Board (or committee thereof), as appropriate (e.g., if the conflict involves the CCO or the Covered Officer reasonably believes it would be futile to report the matter to the CCO).

When actual, apparent or suspected conflicts of interest arise in connection with a Covered Officer, Jackson Fund Services or other Fund personnel aware of the matter should promptly contact the CCO. There will be no reprisal or retaliation against the person reporting the matter.

Upon receipt of a report of a possible conflict, the CCO will take steps to determine whether a conflict exists. In so doing, the CCO may take any actions he or she determines to be appropriate in his or her sole discretion and may use all reasonable resources, including retaining or engaging legal counsel, accounting firms or other consultants, subject to

3

applicable law.² The costs associated with such actions may be borne by the Fund, if appropriate, after consultation with the Fund's Board (or committee thereof).

After full review of a report of a possible conflict of interest, the CCO may determine that no conflict or reasonable appearance of a conflict exists. If, however, the CCO determines that an actual conflict exists, the CCO will resolve the conflict solely in the interests of the Fund, and will report the conflict and its resolution to the Fund's Board (or committee thereof). If the CCO determines that the appearance of a conflict exists, the CCO will take appropriate steps to remedy such appearance. In lieu of determining whether a conflict exists and/or resolving a conflict, the CCO instead may refer the matter to the Fund's Board (or committee thereof), as appropriate. However, the CCO must refer the matter to the Fund's Board (or committee thereof) if the CCO is directly involved in the conflict or under similar appropriate circumstances.

After responding to a report of a possible conflict of interest, the CCO will discuss the matter with the person reporting it (and with the Covered Officer at issue, if different) for purposes of educating those involved on conflicts of interests (including how to detect and avoid them, if appropriate).

Appropriate resolution of conflicts may restrict the personal activities of the Covered Officer and/or his family, friends or other persons.

Solely because a conflict is disclosed to the CCO (and/or the Board or Committee thereof) and/or resolved by the CCO does not mean that the conflict or its resolution constitutes a waiver from the Code's requirements.

Any questions about conflicts of interests, including whether a particular situation might be a conflict or an appearance of one, should be directed to the CCO.

C. Use of Personal Fund Shareholder Information

A Covered Officer may not use or disclose personal information about Fund shareholders, except in the performance of his or her duties for the Fund. Each Covered Officer also must abide by the Fund’s privacy policy under SEC Regulation S-P.

D. Public Communications

In connection with his or her responsibilities for or involvement with the Fund's public communications and disclosure documents (e.g., shareholder reports, registration statements, press releases), each Covered Officer must provide information to Fund service providers and to the Fund's Board (and any committees thereof), independent auditors, government regulators and self-regulatory organizations that is fair, accurate, complete, objective, relevant, timely and understandable.

_________________________

² For example, retaining a Fund's independent accounting firm may require pre-approval by the Fund's audit committee.

4

Further, within the scope of their duties, Covered Officers having direct or supervisory authority over Fund disclosure documents or other public Fund communications will, to the extent appropriate within their area of responsibility, endeavor to ensure full, fair, timely, accurate and understandable disclosure in Fund disclosure documents. Such Covered Officers will oversee, or appoint others to oversee, processes for the timely and accurate creation and review of all public reports and regulatory filings. Within the scope of his or her responsibilities as a Covered Officer, each Covered Officer also will familiarize himself or herself with the disclosure requirements applicable to the Fund, as well as the business and financial operations of the Fund. Each Covered Officer also will adhere to, and will promote adherence to, applicable disclosure controls, processes and procedures which govern the process by which Fund disclosure documents are created and reviewed.

To the extent that Covered Officers participate in the creation of the Fund's books or records, they must do so in a way that promotes the accuracy, fairness and timeliness of those records.

E. Compliance with Applicable Laws, Rules and Regulations

In connection with his or her duties and within the scope of his or her responsibilities as a Covered Officer, each Covered Officer must comply with governmental laws, rules and regulations, accounting standards, and Fund policies/procedures that apply to his or her role, responsibilities and duties with respect to the Fund ("Applicable Laws"). These requirements do not impose on Covered Officers any additional substantive duties. Additionally, Covered Officers should promote compliance with Applicable Laws.

If a Covered Officer knows of any material violations of Applicable Laws or suspects that such a violation may have occurred, the Covered Officer is expected to promptly report the matter to the CCO.

IV. Violation Reporting

A. Overview

Each Covered Officer must promptly report to the CCO, and promote the reporting of, any known or suspected violations of the Officer Code. Failure to report a violation may be a violation of the Officer Code.

Examples of violations of the Officer Code include, but are not limited to, the following:

• Unethical or dishonest behavior

• Obvious lack of adherence to policies surrounding review and approval of public communications and regulatory filings

• Failure to report violations of the Officer Code

• Known or obvious deviations from Applicable Laws

• Failure to acknowledge and certify adherence to the Officer Code

5

The CCO has the authority to take any and all action he or she considers appropriate in his or her sole discretion to investigate known or suspected Code violations, including consulting with the Fund's Board, the independent Board members, a Board committee, and/or the Fund's legal counsel. The CCO also has the authority to use all reasonable resources to investigate violations, including retaining or engaging legal counsel, accounting firms or other consultants, subject to applicable law.³ The costs associated with such actions may be borne by the Fund, if appropriate, after consultation with the Fund's Board (or committee thereof).

B. How to Report

Any known or suspected violations of the Officer Code must be promptly reported to the CCO.

C. Process for Violation Reporting to the Fund Board

The CCO will promptly report any violations of the Code to the Fund's Board (or committee thereof).

D. Sanctions for Code Violations

Violations of the Code will be taken seriously. In response to reported or otherwise known violations, the Fund's Board may impose sanctions within the scope of their respective authority over the Covered Officer at issue. Sanctions imposed by the Fund's Board could include termination of association with the Fund.

V. Waivers from the Officer Code

A Covered Officer may request a waiver from the Officer Code by transmitting a written request for a waiver to the CCO.⁴ The request must include the rationale for the request and must explain how the waiver would be in furtherance of the standards of conduct described in and underlying purposes of the Officer Code. The CCO will present this information to the Fund's Board (or committee thereof). The Board (or committee) will determine whether to grant the requested waiver. If the Board (or committee) grants the requested waiver, the CCO thereafter will monitor the activities subject to the waiver, as appropriate, and will promptly report to the Fund's Board (or committee thereof) regarding such activities, as appropriate. The CCO will coordinate and facilitate any required public disclosures of any waivers granted or any implicit waivers.

_________________________

³ For example, retaining a Fund's independent accounting firm may require pre-approval by the Fund's audit committee.

⁴ Of course, it is not a waiver of the Officer Code if the Fund's Board (or committee thereof) determines that a matter is not a deviation from the Officer Code's requirements or is otherwise not covered by the Code.

6

VI. Amendments to the Code

The CCO will review the Officer Code from time to time for its continued appropriateness and will propose any amendments to the Fund's Board (or committee thereof) on a timely basis. In addition, the Board (or committee thereof) may amend the Code as necessary or appropriate.

The CCO will coordinate and facilitate any required public disclosures of Code amendments.

VII. Acknowledgement and Certification of Adherence to the Officer Code

Each Covered Officer must sign a statement upon appointment as a Covered Officer and annually thereafter acknowledging that he or she has received and read the Officer Code, as amended or updated, and confirming that he or she has complied with it (see Appendix B: Acknowledgement and Certification of Obligations Under the Officer Code).

Understanding and complying with the Officer Code and truthfully completing the Acknowledgement and Certification Form is each Covered Officer's obligation.

The CCO will maintain such Acknowledgements in the Fund's books and records.

VIII. Scope of Responsibilities

A Covered Officer's responsibilities under the Officer Code are limited to:

(1) Fund matters over which the Officer has direct responsibility or control, matters in which the Officer routinely participates, and matters with which the Officer is otherwise involved (i.e., matters within the scope of the Covered Officer's responsibilities as a Fund officer); and

(2) Fund matters of which the Officer has actual knowledge.

IX. Recordkeeping

The CCO will create and maintain appropriate records regarding the implementation and operation of the Officer Code, including records relating to conflicts of interest determinations and investigations of possible Code violations.

7

X. Confidentiality

All reports and records prepared or maintained pursuant to this Officer Code shall be considered confidential and shall be maintained and protected accordingly. Except as otherwise required by law or this Officer Code, such matters shall not be disclosed to anyone other than the CCO, the Fund's Board (or committee thereof), legal counsel, independent auditors, and any consultants engaged by the Compliance Officer.
