Dear Shareholders:
Our commentary for CIGNA Investment Securities (the "Fund") covering the year
ended December 31, 2004 follows.

Management's Discussion of Fund Performance
Market Summary
Bonds gained ground in the first quarter of 2004 as concerns about the
durability of the U.S. economic recovery pushed low interest rates even lower.
Demand for relatively safe assets such as bonds rose amid renewed fears of
terrorist attacks after the Madrid bombing. Lifted by the tailwind of falling
rates, every fixed income sector was in positive territory for the quarter.

Rising interest rates, inflation concerns, and ongoing geopolitical tensions
adversely affected fixed income market performance in the second quarter. The
representative U.S. Lehman Brothers Aggregate Bond Index, benchmark for the
Fund, returned -2.44%, almost completely erasing the 2.66% gains posted in the
first quarter. For the second and first quarters, the Fund returned, based on
the net asset value, -2.34% and 2.39%, respectively.

On June 30, 2004, the Federal Reserve (Fed) increased the federal funds rate 25
basis points for the first time in four years. This widely expected action was
preceded by rising Treasury yields across the maturity spectrum over the second
quarter, with the bellwether 10-year Treasury note rising from a low of 3.65%
in late March to a peak of nearly 5% in June before leveling off.

In the third quarter with an environment of softer-than-expected economic news,
record crude oil prices and persistent geopolitical concerns, the benchmark
Index rallied, returning 3.20% for the period. The Fund returned, based on the
net asset value, 3.04% for the third quarter.

The rally of the third quarter continued into the last three months of the
year, when all major fixed income sectors posted gains, capping a year in which
bonds showed unexpected strength, despite 125 basis points of Fed funds rate
increases. The Fed raised the federal funds rate five times during the year.
Investors understood that the Fed was lifting rates from unusually low levels
that had been set to ward off deflation. The benchmark Index returned 0.95%
compared with 1.07% for the Fund in the fourth quarter.

New Interim Adviser
The Board of Trustees of the Fund approved an interim investment advisory
agreement with BlackRock Advisors, Inc. (BlackRock Advisors) effective November
24, 2004, pursuant to which BlackRock Advisors now serves as investment adviser
to the Fund, responsible for management of the Fund's portfolio.

There has been no change to the investment objective of the Fund as a result of
the appointment of BlackRock Advisors as adviser to the Fund.

During the term of the interim advisory agreement, CIGNA Investment Advisors,
Inc. will provide administrative services to the Fund.

Proposed Merger of the Fund
The Board of Trustees of the Fund approved, subject to Fund shareholder
approval, a reorganization pursuant to which the Fund would transfer
substantially all of its assets and liabilities to BlackRock Core Bond Total
Return Portfolio, a series of BlackRock Funds, an open-end fund managed by
BlackRock Advisors in exchange for Class A shares of BlackRock Core Bond Total
Return Portfolio having a net asset value equal to the net value of the assets
and liabilities so transferred. The shares would then be distributed pro rata
to shareholders of the Fund. Because BlackRock Core Bond Total Return Portfolio
is an open-end fund, its Class A Shares are generally



- --------------------------------------------------------------------------------
                                                                             2

redeemable for an amount equal to their net asset value per share next
determined. The Fund has scheduled a special meeting of shareholders on April
19, 2005 to seek shareholder approval of the merger of the Fund into the
BlackRock Core Bond Total Return Portfolio. You will receive a proxy/
prospectus with additional information about the proposed merger prior to the
meeting. Please be sure to vote.

Proxy Voting Information

A description of the Fund's proxy voting policies and procedures is available
without charge, upon request, by calling the Fund at 1-800-528-6718 and on the
Securities and Exchange Commission's website at www.sec.gov. Information
regarding how the Fund voted proxies relating to portfolio securities during
the 12-month period ended June 30, 2004 is available on the SEC website.

Quarterly Portfolio Securities

The Fund files a complete schedule of portfolio holdings with the SEC for the
first and third quarters of each fiscal year on Form N-Q. Forms N-Q will be
available on the SEC's website at www.sec.gov and may be reviewed and copied at
the SEC's Public Reference Room in Washington, D.C. Information on the
operation of the Public Reference Room may be obtained by calling
1-800-SEC-0330.

Performance

The Fund returned 1.07% and 4.13%, respectively, for the fourth quarter and the
year ending December 31, 2004. The benchmark Index returned 0.95% and 4.34%,
respectively for the same periods. Helped by the increase in the Fund's stock
price following the announcement of the proposed merger discussed above, the
Fund's returns, based on the market value of its shares traded on the New York
Stock Exchange, were 11.67% and 14.33%, respectively, for the fourth quarter
and the year-to-date.

In the first half of the year, the Fund's performance benefited primarily from
its modest short-of-Index duration bias and yield curve positioning as interest
rates rose and the yield curve flattened. In addition, gains from corporate
bond and high yield bond selection helped offset less favorable results from
longer-duration prepayment penalty bonds and structured securities in the MBS
sector. To a lesser extent, performance was also favorably impacted by our
allocation to high yield and investment-grade credits, where we reduced our
exposure during the second quarter.

The primary drivers of the Fund's performance for the third quarter were sector
allocations to and security selections in corporate bonds and high yield. Even
though the bifurcation of performance among issuers and sectors was not
significant in the third quarter, higher beta and lower quality debt did
perform best. Our allocation to emerging market debt and our international (non
dollar) exposure were also positive contributors to results.

In the fourth quarter, the overall positioning of the portfolio was not
drastically changed. After assuming management of the Fund late in November,
BlackRock Advisors looked to sell positions in the credit sectors lacking
relative value and decreased exposure to mortgage-backed securities. Given
their defensive posture on the fixed income markets, BlackRock Advisors took a
slightly more defensive position. At year-end the portfolio had a lower
duration and less exposure to the high yield market, reflecting this posture.

Information about Your Fund's Expenses

As an investor of the Fund, you incur two types of costs: ongoing expenses and
transaction costs. Ongoing expenses include management fees and other Fund
expenses. Examples of transaction costs



- --------------------------------------------------------------------------------
                                                                             3

include exchange commissions, which are not shown in this section and which
would result in higher total expenses (although this Fund does not charge
transaction fees). The following table, which you are seeing for the first
time, represents a new SEC requirement and is intended to help you understand
your ongoing expenses of investing in the Fund and to help you compare these
expenses with the ongoing expenses of investing in other mutual funds. The
table is based on an investment of $1,000 made at the beginning of the
six-month period ended December 31, 2004.

The table illustrates your Fund's expenses in two ways:

Actual Expenses. The first line of the table below provides information about
actual account values and actual expenses. This helps you estimate the actual
dollar amount of ongoing expenses paid on a $1,000 investment in the Fund using
the Fund's actual return during the period. To estimate the expenses you 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
Period."

Hypothetical Example for Comparison Purposes. The second line of the table
below provides information about hypothetical account values and hypothetical
expenses based on the Fund's actual expense ratio 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 your Fund's ongoing expenses with those of other mutual
funds. To do so, compare this 5% hypothetical Fund return with the 5%
hypothetical return examples that appear in the shareholder reports of other
mutual funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing expenses only and do not reflect any transaction costs, such as
exchange commissions. If these transaction costs had been included, your costs
would have been higher. The "Expenses Paid During Period" line of the table is
useful in comparing ongoing expenses only and will not help you determine the
relative total expenses of owning different funds.

   (5% return
   before expenses)     $ 1,000.00     $ 1,019.86      $ 5.33


*    Expenses are equal to the Fund's annualized expense ratio of 1.05%,
     multiplied by the average account value over the period, multiplied by the
     number of days in the most recent fiscal half year period, then divided by
     366. The "Expenses Paid During Period" and the annualized expense ratio are
     based on actual expenses paid by the Fund during the period.

For more information, please refer to the Fund's prospectus.

Outlook
It is our new manager's view that strong faith in the Fed and its gradualism
may yet be threatened by strengthening economic data, particularly evidence
that inflationary pressure is building. The continuing path toward higher, more
normal interest rates is unlikely to be as smooth as last quarter and the
portfolio positioning will reflect this view.

Sincerely,

/s/ Richard H. Forde

(a)  Net investment income per share has been calculated in accordance with SEC
     requirements, with the exception that end of the year accumulated
     undistributed/(overdistributed) net investment income has not been adjusted
     to reflect current year permanent differences between financial and tax
     accounting.

(b)  Total investment return based on per share net asset value reflects the
     effects of changes in net asset value on the performance of the Fund during
     each period, and assumes distributions were reinvested at net asset value.
     These percentages may not correspond with the performance of a
     shareholder's investment in the Fund based on market value, since the
     relationship between the market price of the stock and net asset value
     varied during each period.

(c)  Effective January 1, 2001, the Fund was required to start amortizing
     premium and discount on all debt securities. The effect of this change on
     net investment income per share was a decrease of $0.01 per share. The
     effect to the ratio of net investment income to average net assets was a
     decrease of 0.07%. Per share, ratios, and supplemental data for periods
     prior to January 1, 2001 have not been restated to reflect this change in
     accounting principle.

The Notes to Financial Statements are an integral part of these statements.

CIGNA Investment Securities Notes to Financial Statements                   15

1. Organization. CIGNA Investment Securities (the "Fund") is registered under
the Investment Company Act of 1940, as amended, as a diversified, closed-end
management investment company. The Fund's objective is to generate income and
obtain capital appreciation by investing, under normal market conditions, at
least 65% of its total assets in investment-grade debt securities and preferred
stocks.

2. Significant Accounting Policies. The preparation of financial statements in
accordance with accounting principles generally accepted in the United States
of America requires management to make estimates and assumptions that affect
the reported amounts and disclosures in the financial statements. Actual
results could differ from those estimates. The following is a summary of
significant accounting policies consistently followed by the Fund in the
preparation of its financial statements.

A. Security Valuation -- Debt securities traded in the over-the-counter market,
including listed securities whose primary markets are believed to be
over-the-counter, are valued on the basis of valuations furnished by brokers
trading in the securities or a pricing service, which determines valuations for
normal, institutional-size trading units of such securities using market
information, transactions for comparable securities and various relationships
between securities which are generally recognized by institutional traders.
Short-term investments with remaining maturities of up to and including 60 days
are valued at amortized cost, which approximates market. Short-term investments
that mature in more than 60 days are valued at current market quotations. Other
securities and assets of the Fund are appraised at fair value, as determined in
good faith by, or under the authority of, the Fund's Board of Trustees. The
Fund's Board of Trustees has designated the Pricing Committee of CIGNA
Investment Advisors, Inc. (formerly, TimesSquare Capital Management, Inc.) to
make, pursuant to procedures approved by the Board and under the Board's
supervision, all necessary determinations of fair value for the portfolio
securities for which market quotations are not readily available. When fair
valuing securities, the Pricing Committee takes into account factors such as
fundamental and analytical information about the security, the nature and
duration of any restrictions on disposition of the security, market information
(including, for example, factors such as historical price relationships and
valuations for securities with similar characteristics), and evaluation of
significant market events. If events occurring after the close of the principal
market in which securities are traded (but before the close of regular trading
on the NYSE) are believed to materially affect the value of those securities,
such securities are valued at their fair value taking such events into account.

B. Delayed Delivery Commitments -- The Fund may enter into commitment
agreements, i.e., TBA's, for the purchase of securities at an agreed-upon price
on a specified future date. Since the delivery and payment for such securities
can be scheduled to take place up to three months after the transaction date,
they are subject to market fluctuations. The Fund does not begin to earn
interest on such purchase commitments until settlement date. The Fund may sell
a purchase commitment prior to settlement for the purpose of enhancing its
total return. The Fund segregates assets with a market value equal to the
amount of its purchase commitments. To the extent securities are segregated,
they may not be available for new investments or to meet redemptions. Delayed
delivery commitments may increase the Fund's exposure to market fluctuations
and may increase the possibility that the Fund may realize a short-term gain
(subject to taxation) or loss if the Fund must engage in portfolio transactions
in order to honor its commitments. Due to the longer settlement period, there
may be an increased risk of failure of the other party to honor the
transaction. The Fund records changes in market value of the



- --------------------------------------------------------------------------------
CIGNA Investment Securities Notes to Financial Statements (Continued)       16

securities underlying unsettled commitments in unrealized gains and losses.
Gains and losses are realized upon sale of the commitment.

C. Foreign Currency Translations -- Foreign currency transactions from foreign
investment activity are translated into U.S. dollars on the following basis:

(1)  market value of investment securities, other assets and liabilities at the
     daily rates of exchange, and

(2)  purchases and sales of investment securities, dividend and interest income
     and certain expenses at the rates of exchange prevailing on the respective
     dates of such transactions.

The Fund does not isolate that portion of gains and losses on investments which
is due to changes in foreign exchange rates from that which is due to changes
in market prices of the investments. Such fluctuations are included with the
net realized and unrealized gains and losses from investments.

Net realized and unrealized gains (losses) from foreign currency-related
transactions include gains and losses between trade and settlement dates on
securities transactions, gains and losses arising from the sales of foreign
currency, and gains and losses between the ex-dividend and payment dates on
dividends, interest, and foreign withholding taxes.

D. Foreign Investments -- The Fund may invest in securities of foreign
countries and governments, which involve certain risks in addition to those
inherent in domestic investments. Such risks generally include, among others,
currency risk (fluctuations in currency exchange rates), information risk (key
information may be inaccurate or unavailable) and political risk
(expropriation, nationalization or the imposition of capital or currency
controls or punitive taxes). Other risks of investing in foreign securities
include inadequate accounting controls, liquidity and valuation risks.

E. Forward Currency Transactions -- The Fund is authorized to enter into
forward exchange contracts for the purpose of hedging against foreign exchange
risk arising from the Fund's investment or anticipated investment in securities
denominated in foreign currencies. The Fund may also enter into these contracts
for purposes of increasing exposure to a foreign currency or to shift exposure
to foreign currency fluctuations from one country to another. All commitments
are marked to market daily at the applicable translation rates and any
resulting unrealized gains or losses are recorded. Realized gains or losses are
recorded at the time the forward contract matures or by delivery of the
currency. Due to market fluctuations, the Fund segregates assets with a market
value equal to the amount of its purchase commitments. Risks may arise upon
entering into these contracts from the potential inability of counterparties to
meet the terms of their contracts and from unanticipated movements in the value
of a foreign currency relative to the U.S. dollar.

F. Futures Contracts -- The Fund is authorized to enter into futures contracts.
A Fund may use futures contracts for reasons such as managing its exposure to
the markets or movements in interest rates and currency values. Upon entering
into a futures contract, the Fund is required to pledge to the broker an amount
of cash and/or securities equal to the initial margin requirements. During the
period a futures contract is open, changes in the value of a contract are
recognized as unrealized gains or losses by "marking to market" on a daily
basis to reflect the market value of the contract at the end of each day's
trading. Daily variation margin payments are received or made, depending on
whether there were unrealized gains or losses. When a contract is closed, the
Fund records a realized gain or loss equal to the difference between the value
of the contract at the time it was opened and the value at the time it was
closed. Futures contracts include the risk that a



- --------------------------------------------------------------------------------
CIGNA Investment Securities Notes to Financial Statements (Continued)       17

change in the value of the contract may not correlate with the value of the
underlying securities and the possibility of an illiquid market.

G. High Yield Bonds -- The Fund may invest in high yield bonds i.e., fixed
income securities rated below investment-grade. While the market values of
these securities tend to react less to fluctuations in interest rate levels
than do those of investment-grade securities, the market values of certain of
these securities also tend to be more sensitive to individual corporate
developments and changes in economic conditions than investment-grade
securities. In addition, these securities are often highly leveraged and may
not have more traditional methods of financing available to them so that their
ability to service their debt obligations during an economic downturn or during
sustained periods of rising interest rates may be impaired.

H. Swap Agreements -- The Fund may enter into swap agreements for investment,
liquidity, hedging and risk management purposes. For example, the Fund may
enter into swap agreements to preserve a return on a particular investment or a
portion of its portfolio and as a technique for managing duration (i.e., price
sensitivity to changes in interest rates). Swaps involve the exchange of
commitments to pay or receive, e.g., an exchange of floating rate payments for
fixed rate payments and/or payments of the appreciation or depreciation of a
security or an index. If forecasts of interest rates and other market factors,
including those that may impact the indexes of the total return swaps, are
incorrect, investment performance will differ compared to what performance
would have been if these investment techniques were not used. Even if the
forecasts are correct, there are risks that the positions may correlate
imperfectly with the asset or liability being hedged, a liquid secondary market
may not always exist, or the counterparty to a transaction may default.

For swaps entered into during the year, the terms of the agreement required the
Fund to pay LIBOR (which is set monthly) plus a spread and to receive the
monthly total return on the Index, both based on the notional amount. The Fund
recorded the net amount receivable/payable on a daily basis. The net
receivable/payable was settled in cash monthly and recorded as realized gain/
loss. As of December 31, 2004, the Fund did not have any outstanding swap
agreements.

I. Security Transactions and Related Investment Income -- Security transactions
are accounted for on the trade date (date the order to buy or sell is
executed). Dividend income is recorded on the ex-dividend date, and interest
income, which includes amortization of premium and accrual of discount, is
recorded on the accrual basis. Securities gains and losses are determined on
the basis of identified cost.

J. Federal Taxes -- It is the Fund's policy to continue to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of its taxable income or capital gains to its
shareholders. Therefore, no federal income or excise taxes on realized income
have been accrued. Distributions reported in the Statement of Changes in Net
Assets from net investment income, including short-term capital gains, and
capital gains are treated as ordinary income and long-term capital gains,
respectively, for federal income tax purposes.

At December 31, 2004, the Fund had a post-October loss of $31,233, of which
$47,577 was a post-October currency loss. Under current tax law, capital losses
realized after October 31 may be deferred and treated as if occurring on the
first day of the following year.

K. Dividends and Distributions to Shareholders -- Dividends from net investment
income are declared and distributed quarterly and distributions from net
capital gains, to the extent such gains would otherwise be taxable to the



- --------------------------------------------------------------------------------
CIGNA Investment Securities Notes to Financial Statements (Continued)       18

Fund, are declared and distributed at least annually. Dividends and
distributions are recorded by the Fund on the ex-dividend date. The timing and
characterization of certain income and capital gains distributions are
determined in accordance with federal tax regulations, which may differ from
generally accepted accounting principles. These differences are primarily due
to differing book and tax treatment of premium amortization, deferred
compensation, interest on defaulted securities, foreign currency transactions,
capital loss carryforwards, deferred losses due to wash sales, and excise tax
regulations. To the extent that such differences are permanent, a
reclassification to the Components of Net Assets may be required. As a result,
at December 31, 2004, the Fund decreased overdistributed net investment income
by $803,828, increased accumulated net realized loss by $704,953 and decreased
paid in capital by $98,875.

3. Investment Advisory Fees and Other Transactions with Affiliates. Through
November 23, 2004, investment advisory fees, in the amount of $410,624, were
paid or accrued to CIGNA Investment Advisors, Inc. ("CIAI") (formerly,
TimesSquare Capital Management, Inc.), certain officers and directors of which
are affiliated with the Fund.

Effective November 24, 2004, the Board of Trustees approved an interim
investment advisory agreement with BlackRock Advisors, Inc. ("BlackRock"),
pursuant to which BlackRock now serves as investment adviser to the Fund.
Advisory fees, in the amount of $49,007, was paid or accrued to BlackRock. Such
advisory fees for both CIAI and BlackRock were and are, respectively, based on
an annual rate of 0.55% of the first $75 million of average weekly net asset
value and 0.40% thereafter.

CIAI is an indirect, wholly-owned subsidiary of CIGNA Corporation.

Pursuant to an Exemptive Order issued by the Securities and Exchange
Commission, and as approved by the shareholders at the shareholder meeting of
April 30, 2002, the Fund may invest excess cash, up to 25% of the Fund's total
assets, in the affiliated CIGNA Funds Group Money Market Fund (MMF) managed by
CIAI. CIAI will waive the amount of its advisory fee for the Fund in an amount
that offsets the amount of the advisory fees incurred in the Fund as a result
of its investment in MMF. For the year ended December 31, 2004, CIAI waived
$13,504 of its advisory fee payable by the Fund. Income distributions from MMF,
which amounted to $31,344 for the year ended December 31, 2004, are recorded as
dividend income in the Statement of Operations.

For administrative services, the Fund reimburses CIAI for a portion of the
compensation and related expenses of the Trust's Treasurer and Secretary and
certain persons who assist in carrying out the responsibilities of those
offices. Effective November 24, 2004, CIAI entered into an administrative
services agreement with the Fund under which CIAI receives 0.05% of the Fund's
average weekly net assets. For the year ended December 31, 2004, the Fund paid
or accrued $45,889.

4. Trustees' Fees. Trustees' fees represent remuneration incurred for trustees
who are not employees of CIGNA Corporation or any of its affiliates. Trustees
may elect to defer receipt of all or a portion of their fees, which are
invested in mutual fund shares in accordance with a deferred compensation plan.

5. Purchases and Sales of Securities.
Purchases and sales of securities for the year ended December 31, 2004, were as
follows (excluding short-term obligations):



                                    Cost of       Proceeds From

6. Proposed Merger of the Fund. The Board of Trustees of the Fund approved,
subject to Fund shareholder approval, a reorganization pursuant to which the
Fund would transfer substantially all of its assets and liabilities to
BlackRock Core Bond Total Return Portfoli, a series of BlackRock Funds, an
open-end fund managed by BlackRock Advisors in exchange for Class A shares of
BlackRock Core Bond Total Return Portfolio having a net asset value equal to
the net value of the assets and liabilities so transferred. The shares would
then be distributed pro rata to shareholders of the Fund. Because BlackRock
Core Bond Total Return Portfolio is an open-end fund, its Class A Shares are
generally redeemable for an amount equal to their net asset value per sahre
next determined. The Fund has scheduled a special meeting of shareholder
approval of the merger of the Fund into the BlackRock Core Bond Total Return
Portfolio.

Report of Independent Registered Public Accounting Firm

To the Trustees and Shareholders of CIGNA Investment Securities

In our opinion, the accompanying statement of assets and liabilities, including
the investments in securities, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of CIGNA Investment Securities (the
"Fund") at December 31, 2004, and the results of its operations, the changes in
its net assets and the financial highlights for the periods indicated, in
conformity with accounting principles generally accepted in the United States
of America. These financial statements and financial highlights (hereafter
referred to as "financial statements") are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these financial
statements in accordance with auditing standards of the Public Company
Accounting Oversight Board (United States). These standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit 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, and evaluating the overall financial
statement presentation. We believe that our audits, which included confirmation
of securities at December 31, 2004 by correspondence with the custodian,
provide a reasonable basis for our opinion.

2004 Tax Information
During 2004, the Fund declared dividends of $0.90 per share. For federal income
tax purposes, all of these dividends were ordinary income dividends. There were
no capital gain distributions. Dividends reported to you as ordinary income
dividends on Form 1099, whether received as stock or cash, must be included in
your federal income tax return and must be reported by the Fund to the Internal
Revenue Service.

The Fund hereby designates 0.45% or the maximum amount allowable of its net
taxable income as qualified dividends as provided in the Jobs and Growth Tax
Relief Reconciliation Tax Act of 2003. The 2004 Form 1099-DIV you receive will
show the tax status of all distributions paid to you during the year.

Approximately 0.45% of ordinary income dividends would be eligible for the
dividend received deduction (available to corporate shareholders only).

Approximately 13.25% of ordinary income dividends for the year was derived from
U.S. Government Treasury Obligations, and 34.96% from U.S. Government Agency
obligations.

At December 31, 2004, 57.4% of the Fund's net assets were invested in U.S.
Government and Agency Obligations.

Automatic Dividend and Distribution Investment Plan
Shareholders may elect to have all distributions of dividends and capital gains
automatically reinvested by EquiServe (the "Dividend Paying Agent") as plan
agent under the Automatic Dividend and Distribution Investment Plan (the
"Plan"). Shareholders who do not elect to participate in the Plan will receive
all distributions from the Fund in cash, paid by check mailed directly to the
shareholder by the Dividend Paying Agent. Shareholders may elect to participate
in the Plan and to have all distributions of dividends and capital gains
automatically reinvested by sending written instructions to the Dividend Paying
Agent at the address set forth below on the following page.

If the Trustees of the Fund declare a dividend or determine to make a capital
gains distribution payable either in shares of the Fund or in cash, as
shareholders may have elected, non-participants in the Plan will receive cash
and participants in the Plan will receive the equivalent in shares. If the
market price of the shares as of the close of business on the payment date for
the dividend or distribution is equal to or exceeds their net asset value as
determined as of the close of business on the payment date, participants will
be issued shares of the Fund at a value, equal to the higher of net asset value
or 95% of the market price. If net asset value exceeds the market price of the
shares at such time, or if the Fund declares a dividend or other distribution
payable only in cash, the Dividend Paying Agent will, as agent for Plan
participants, buy shares in the open market, on the New York Stock Exchange or
elsewhere, for the participants' accounts. If, before the Dividend Paying Agent
has completed its purchases, the market price exceeds the net asset value of
the shares, the average per share purchase price paid by the Dividend Paying
Agent may exceed the net asset value of the shares, resulting in the
acquisition of fewer shares than if the dividend or distribution had been paid
in shares issued by the Fund.

Participants in the Plan may withdraw from the Plan upon written notice to the
Dividend Paying Agent. When a participant withdraws from the Plan or upon
termination of the Plan as provided below, certificates for the whole shares
credited to his or her account under the Plan will be issued and a cash payment
will be made for any fraction of a share credited to such account.



- --------------------------------------------------------------------------------
CIGNA Investment Securities                                                 22
(Unaudited)

The Dividend Paying Agent will maintain all shareholders' accounts in the Plan
and will furnish written confirmation of all transactions in the account,
including information needed by shareholders for tax records. Shares in the
account of each Plan participant (other than participants whose shares are
registered in the name of banks, brokers, nominees or other third parties) will
be held by the Dividend Paying Agent in the non-certificated form in the name
of the participant, and each shareholder's proxy will include those shares
purchased pursuant to the Plan. At no additional cost, shareholders of the Fund
may send to the Dividend Paying Agent for deposit into their Plan account those
share certificates in their possession. Shareholders may also send share
certificates to the Dividend Paying Agent for the Dividend Paying Agent to hold
in a book-entry account outside of the Plan.

Whether or not shareholders participate in the Plan, they may elect by notice
to the Dividend Paying Agent to have the Dividend Paying Agent sell their
noncertificated book-entry shares. The Dividend Paying Agent will deduct from
the sale proceeds $2.50 per transaction plus $0.15 per share and remit the
balance of the sales proceeds to the shareholder. The Dividend Paying Agent
will sell the noncertificated shares on the first trading day of the week
immediately following receipt of written notification by the Dividend Paying
Agent.

In the case of shareholders, such as banks, brokers or nominees which hold
shares for others who are the beneficial owners, the Dividend Paying Agent will
administer the Plan on the basis of number of shares certified, from time to
time, by the record shareholders as representing the total amount registered in
the record shareholder's name and held for the account of beneficial owners who
are to participate in the Plan. Investors whose shares are held in the name of
banks, brokers or nominees should confirm with such entities that participation
in the Plan will be possible, and should be aware that they may be unable to
continue to participate in the Plan if their account is transferred to another
bank, broker or nominee. Those who do participate in the Plan may subsequently
elect not to participate by notifying such entities.

There is no charge to participants for reinvesting dividends or distributions,
except for certain brokerage commissions, as described below. The Dividend
Paying Agent's fees for the handling of the reinvestment of dividends and
distributions will be paid by the Fund. However, each participant will pay a
pro rata share of brokerage commissions incurred with respect to the Dividend
Paying Agent's open market purchases in connection with the reinvestment of
dividends or distributions.

Participants in the Plan should be aware that they will realize capital gains
and income for tax purposes upon dividends and distributions, although they
will not receive any payment of cash.

Experience under the Plan may indicate that changes are desirable. Accordingly,
the Fund reserves the right to amend or terminate the Plan as applied to any
dividend or distribution paid subsequent to written notice of the change sent
to the participants in the Plan at least 90 days before the record date for
such dividend or distribution. The Plan also may be amended or terminated by
the Dividend Paying Agent on at least 90 days' written notice to participants
in the Plan. All correspondence concerning the Plan, including requests for
additional information or an application brochure or general inquiries about
your account, should be directed to EquiServe, P.O. Box 43011, Providence, RI
02940-3011 or you may call toll free 1-800-426-5523.
