Dear Shareholders:

Our report for CIGNA Investment Securities (the "Fund") covering the six months
ended June 30, 2004 follows.

Market Summary

Rising interest rates, inflation concerns, and ongoing geopolitical tensions
adversely affected fixed income market performance in the second quarter. The
representative Lehman Brothers Aggregate Bond Index returned -2.44%, almost
erasing the 2.66% gains posted in the first quarter.

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.

Steadily improving credit and liquidity profiles of many issuers continued to
benefit investment-grade corporate bond valuations. Nevertheless, the sector,
represented by the Lehman Brothers U.S. Credit Index, returned -3.43% for the
second quarter, surrendering most of the 3.27% gained in the first quarter.

During the first quarter in the Mortgage Backed Securities (MBS) market, banks
and foreign investors were attracted to the high yield from MBS and absorbed
some of the supply, strong technicals helped valuations remain at high levels,
and the recent wave of refinancing slowed to keep volatility low. In this
environment, the Lehman Brothers MBS Index generated a return of 1.92%. MBS
started the second quarter under pressure, as investors faced extending
durations and declining prices. By mid-quarter, MBS had recovered modestly, and
then registered strong gains in June to end the second quarter as the best
performer in the Aggregate Bond Index.

High yield sector performance moderated from its strong recovery in 2003, as
the Lehman Brothers U.S. High Yield Index generated a 1.35% return for the six
months ended June 30, 2004. Risk aversion creeping back into the market and
issuer-specific weaknesses contributed to the performance slump.

Emerging debt markets tumbled in the second quarter, with the JP Morgan
Emerging Markets Bond Index Plus registering a return of -5.89%, down from
3.26% in the first quarter.

Performance
The Fund returned -0.01% for the year-to-date based on its net asset value,
underperforming the Lehman Brothers Aggregate Bond Index return of 0.16% by 17
bps. The Fund's return, based on the market value of its shares traded on the
New York Stock Exchange, was -5.57% for the year-to-date.

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.

Outlook
With the economy on track to steadily improve, barring any political or
geopolitical setbacks, Treasury yields should continue to rise. We remain
constructive on investment-grade corporate bonds as valuations and break-even
spreads continue to offer value and positive excess return potential. We will
also remain vigilant in our sector allocation and security selection and
monitor various risk factors that could impede improvement in credit spreads.


Sincerely,

/s/ Richard H. Forde

Richard H. Forde
Chairman of the Board and President
CIGNA Investment Securities

(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.
(d) Not annualized.
(e) Annualized.

(Unaudited)

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 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 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:

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

(ii)  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 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, the issuers of 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. As of
June 30, 2004, the Fund had no 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, 2003, the Fund had a post-October loss of $113,141, of which
$30,568 was a post-October currency loss. Under current tax law, capital losses
realized after October 31 may be deferred and treated as 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 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, 2003, the Fund decreased
overdistributed net investment income by $1,582,540, increased accumulated net
realized gain by $1,521,666 and decreased paid in capital by $60,874.

3. Investment Advisory Fees and Other Transactions with Affiliates.  Investment
advisory fees were paid or accrued to TimesSquare Capital Management, Inc.
("TimesSquare"), certain officers and directors of which are affiliated with
the Fund. Such advisory fees are based on an annual rate of 0.55% of the first
$75 million of average weekly net asset value and 0.40% thereafter. TimesSquare
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
TimesSquare. TimesSquare 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 six months ended June 30, 2004,
TimesSquare waived $8,549 of its advisory fee payable by the Fund. Income
distributions from MMF, which amounted to $15,432 for the six months ended June
30, 2004, are recorded as dividend income in the Statement of Operations.

For administrative services, the Fund reimburses TimesSquare 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. For the six months ended June 30, 2004, the Fund paid or accrued
$22,983.

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
six months ended June 30, 2004, were as follows (excluding short-term
obligations):

Dividend Rate Change
The quarterly income dividend of 22 cents per share, which the Fund declared on
August 17, 2004, is payable on September 10, 2004 to shareholders of record on
August 27, 2004. This new rate is a reduction from the 23 cents per-share rate
the Fund has paid since June 10, 2003.

This change takes into consideration both a reduction in the Fund's high yield
credit exposure, as we currently believe that the market has fully priced in
the improved risk profile of this sector, and the general trend that higher
coupon bonds purchased by the Fund in earlier years have gradually been
replaced by lower coupon issues, as the original bonds have either matured,
been called or sold for investment and credit reasons.
