Shading within the style matrix approximates areas in which the Fund is designed
to generally invest.

The style matrix can be a valuable tool for constructing and monitoring your
portfolio. It provides a frame of reference for distinguishing the types of
stocks or bonds owned by a mutual fund, and may serve as a guideline for helping
you build a portfolio.

Investment products, including shares of mutual funds, are not federally or
FDIC-insured, are not deposits or obligations of, or guaranteed by any financial
institution, and involve investment risks including possible loss of principal
and fluctuation in value.

The products of technology companies may be subject to severe competition and
rapid obsolescence, and technology stocks may be subject to greater price
fluctuations, government regulation, and limited liquidity as compared to other
investments. In addition, investments in one economic sector, such as
technology, may result in greater price fluctuations than owning a portfolio of
diversified investments. Investments in small- and mid-capitalization companies
involve greater risks and potential volatility than investments in larger, more
established companies. See the Fund's prospectus for information on these and
other risks associated with the Fund.

MANAGER COMMENTARY -------------------------------------------------------------



Dear Shareholders,

Seligman Communications and Information Fund (the Fund) Class A shares gained
59.92% (excluding sales charge) for the 12 months ended Dec. 31, 2009. The Fund
underperformed its benchmark, the S&P North American Technology Sector Index
(the S&P NATS Index), which rose 63.19% for the 12-month period. The Fund
outperformed its peer group, as measured by the Lipper Science & Technology
Funds Index, which increased 57.90% for the same period.

SIGNIFICANT PERFORMANCE FACTORS
The economic environment firmed as the year progressed. The technology industry
was not as adversely affected by the economic malaise as many had expected.
Business spending, on software in particular, proved to be fairly resilient,
attributable to the fact that so many business processes are mission critical.
The software industry was also supported by the necessity of ongoing maintenance
payments for continued product use.

Further supporting the technology industry in 2009 was the unexpected strength
of personal computers (PCs) and cell phones sales. While the final figures of
worldwide sales are not yet available, it is estimated that PC unit sales ended
down only 8% in 2009, a figure much better than

analysts expected. PC demand in emerging economies -- which fared better,
overall, than developed economies in the recession -- is surging where
penetration levels are still low. The cell phone market also held up well, due
mainly to the ongoing move to smart phones with greater functionality and
Internet features. Multitudinous product launches and innovations have prompted
consumers to replace their phones in greater frequency than was perhaps seen
only a few years ago.

The electronics industry was a prime beneficiary of the improvement we saw in PC
and cell phone sales as the year progressed. Inventories were rebuilt throughout
the electronics industry supply chain, which gave rise to significant positive
earnings surprises within semiconductors in particular, but also through many
areas of electronics, beginning in June and extending through year-end.
Semiconductors had been negatively impacted the most in 2008 and returned as the
strongest performing industry in 2009. Overall, IT spending was in the negative
single digits, not a cataclysmic decline, as compared to other market sectors.

Software was the Fund's largest weighting, considerably overweight, relative to
the S&P NATS Index during the year and stock selection, particularly within
systems software was a significant contributor to the

Fund's investment results, on an absolute and relative basis. Notable names
within software included CHECK POINT SOFTWARE TECHNOLOGIES, SYMANTEC, MCAFEE,
SYNOPSIS, AMDOCS, OPEN TEXT, MICROSOFT, BMC SOFTWARE, and PARAMETRIC TECHNOLOGY.

The semiconductor industry also contributed significantly to the Fund's results
during the year. The Fund maintained a sizable underweight, relative to the S&P
NATS Index during the year, but stock selection led the Fund to substantially
outperform the index. Most outstanding was the Fund's holding in chip
manufacturer MARVELL TECHNOLOGY GROUP.

The Fund was underweight in computer and peripherals, an industry that
outperformed for the year. While the allocation detracted from relative
performance, stock selection more than overcame the detraction, with strong
results from APPLE, NETAPP, EMC and HEWLETT-PACKARD. The Fund also maintained an
underweight in communications equipment. Strong contributions from RIVERBED
TECHNOLOGY (which the Fund no longer owns), QUALCOMM and CISCO SYSTEMS added to
the Fund's results.

Within the health care sector, an area which is not represented in the S&P NATS
Index, the Fund benefited from its position in LIFE TECHNOLOGIES as well as from
ADVANCED MEDICAL OPTICS, which was acquired in Feb. 2009 by ABBOTT LABORATORIES,
a company which the Fund also owns.

The largest areas of relative detraction came from areas in which the Fund was
not invested, or was late to the game. The Fund had little exposure to


  We currently view the technology sector as a rising tide that's lifting all
  boats.

MANAGER COMMENTARY (continued) -------------------------------------------------


contract manufacturing services, an area that rallied strongly during the year.
Commodity semiconductor companies, such as those that produce flash memory and
DRAM chips, which were among the top performing semiconductor companies in 2009
was also an area of missed opportunity. Certain travel-related Internet sites
and online retailers that garnered strong returns were also missed opportunities
for the Fund.

The Fund was also modestly involved with disk drive stocks, which proved to be
extremely strong during the year. The Fund did own WESTERN DIGITAL and SEAGATE
TECHNOLOGY, which returned disappointing results.

CHANGES TO THE FUND'S PORTFOLIO
The only notable change to our allocations was with regard to the semiconductor
capital equipment. The Fund had minimal exposure to the area at the start of the
year. We added positions in this industry to the Fund, such as NOVELLUS SYSTEMS,
PARADYNE, and VERIGY in response to the dramatically improving capital spending
environment as fundamentals in the electronics industry improved and balance
sheets of chip companies strengthened. We've also seen a great improvement in
pricing (more than doubling from their lows) for commodity semiconductors,
especially for DRAM memory chips and band flash chips, which further supports
our rationale for increasing the Fund's exposure to this industry.

While we continue to maintain a significant overweight in software, we pared
back considerably our exposure to video game software during the year. Given the
rise of social networking websites, as well as the advent of casual games on
platforms such as the iPhone and iPod touch, we saw declining prospects for this
niche of the software industry. This tactical move proved advantageous as video
game stocks delivered disappointing results on the whole in 2009.

While we did not implement any significant industry re-allocations, we took
advantage of opportunities present in the market to add to return. For example,
we added to our position in Marvell Technology at an attractive price, which
proved fortuitous when Marvell rallied strongly from the bottom. We also added
to the Fund's position in Apple at the nadir early in 2009 when CEO and co-
founder Steve Jobs announced he was taking a

8  SELIGMAN COMMUNICATIONS AND INFORMATION FUND -- 2009 ANNUAL REPORT



- --------------------------------------------------------------------------------


medical leave of absence. Apple's stock price rebounded, more than doubling from
the level at which we added to the position.

OUR FUTURE STRATEGY
IT budgets are showing signs of improving in 2010. It appears that global
enterprise spending, or at least budgetary intentions, for 2010 indicate a 4-5%
growth in IT budgets. There seems to be pent-up demand for storage and servers,
so data center equipment certainly may be on the upswing. We are anticipating
strong results from data center-centric companies as earnings results are
announced in the first quarter of 2010.

We also anticipate meaningful improvement in software projects that have been
held on pause for some time now that the recovery is showing some legs and we
have experienced some stabilization. We anticipate a nice recovery in enterprise
software demand for new licenses and for new products as 2010 unfolds.

Within semiconductors, we anticipate a significant increase in capital spending.
Semiconductors are coming off very depressed levels. Factoring in the rising
prices of commodity chips and the high utilization rates in existing chip
factory facilities, we believe current forecasts of 50-60% growth in capital
spending within semiconductors may be proven correct.

We are seeing vast improvements in the financing environment. We anticipate a
marked increase in initial public offering activity within the technology sector
in 2010. Valuations among technology companies are running a wide spectrum
currently. While some technology companies are at frothy levels, there are still
many companies out there with reasonable valuations. We are finding more value
in larger companies, as companies with smaller floats (small capitalization
structure) are pricing in at the expensive end of the spectrum. We plan to
navigate carefully, likely underweighting smaller, more expensive companies, as
we anticipate secondary offerings with many of these companies, many of which
are in the software and Internet-related areas. We are fairly positive about the
prospects for software and plan to continue to overweight the industry.

There are still a lot of technology companies that are flush with cash, which
lends to our anticipation of a step-up in acquisition activity, as well as
increased share repurchases. We also anticipate that, as the

</Table>




(1) The S&P North American Technology Sector Index (the "NATS Index"), an
    unmanaged benchmark, is a modified capitalization-weighted index based on a
    universe of technology related stocks. The index reflects reinvestment of
    all distributions and changes in market prices.
(2) The Lipper Science & Technology Funds Index (Lipper Index) includes the 30
    largest science and technology tracked by Lipper Inc. The Lipper Index's
    returns include net reinvested dividends.*
(3) The Lipper Science & Technology Funds Average (Lipper Average), an unmanaged
    benchmark, measures the performance of mutual funds that invest at least 65%
    of their equity portfolios in science and technology stocks. The average
    reflects reinvestment of all distributions and changes in market prices.*
*   On Jan. 1, 2010, the Lipper Index replaced the Lipper Average as the Fund's
    secondary benchmark. The Lipper Average includes all funds categorized by
    Lipper within the broad universe of funds in the Lipper Average, whereas the
    Lipper Index includes only a select peer group from the Lipper Average, as
    described above. This change was made to bring the selection of the Seligman
    Fund secondary benchmarks in line with the practice of the RiverSource
    Family of Funds, which would permit a common shareholder experience and
    provide a more focused peer group for performance comparison purposes.
    Information on both the Lipper Index and the Lipper Average will be included
    for a one-year transition period. Thereafter, only the Lipper Index will be
    included.

FUND EXPENSES EXAMPLE ----------------------------------------------------------
(UNAUDITED)

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments; and (2) ongoing
costs, which may include management fees; distribution and service (12b-1) fees;
and other Fund fees and expenses. This example is intended to help you
understand your ongoing costs (in dollars) of investing in the Fund and to
compare these costs with the ongoing costs of investing in other mutual funds.
In addition to the ongoing expenses which the Fund bears directly, the Fund's
shareholders indirectly bear the ongoing expenses of any funds in which the Fund
invests (also referred to as "acquired funds"), including affiliated and non-
affiliated pooled investment vehicles (including mutual funds and exchange
traded funds). The Fund's indirect expense from investing in the acquired funds
is based on the Fund's pro rata portion of the ongoing expenses charged by
acquired funds using the expense ratio of each of the acquired funds as of the
acquired fund's most recent shareholder report.

The example is based on an investment of $1,000 invested at the beginning of the
period and held until Dec. 31, 2009.

ACTUAL EXPENSES
The first line of the table provides information about actual account values and
actual expenses. You may use the information in this line, together with the
amount you invested, to estimate the expenses that you 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 titled "Expenses paid during the period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The second line of the table 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 the ongoing costs of investing in the
Fund and other funds. To do so, compare this 5% hypothetical example with the 5%
hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads). Therefore, the second line of the table is useful in comparing
ongoing costs only, and will not help you determine the relative total costs of
owning different funds. In addition, if these transactional costs were included,
your costs would have been higher.

FAIR VALUE MEASUREMENTS


Generally accepted accounting principles (GAAP) require disclosure regarding the
inputs and valuation techniques used to measure fair value and any changes in
valuation inputs or techniques. In addition, investments shall be disclosed by
major category.

The Fund categorizes its fair value measurements according to a three-level
hierarchy that maximizes the use of observable inputs and minimizes the use of
unobservable inputs by prioritizing that the most observable input be used when
available. Observable inputs are those that market participants would use in
pricing an investment based on market data obtained from sources independent of
the reporting entity. Unobservable inputs are those that reflect the Fund's
assumptions about the information market participants would use in pricing an
investment. An investment's level within the fair value hierarchy is based on
the lowest level of any input that is deemed significant to the asset or
liability's fair value measurement. The input levels are not necessarily an
indication of the risk or liquidity associated with investments at that level.
For example, certain U.S. government securities are generally high quality and
liquid, however, they are reflected as Level 2 because the inputs used to
determine fair value may not always be quoted prices in an active market.

Fair value inputs are summarized in the three broad levels listed below:

     - Level 1 -- Valuations based on quoted prices for investments in active
       markets that the Fund has the ability to access at the measurement date.
       Valuation adjustments are not applied to Level 1 investments.

     - Level 2 -- Valuations based on other significant observable inputs
       (including quoted prices for similar securities, interest rates,
       prepayment speeds, credit risks, etc.).

     - Level 3 -- Valuations based on significant unobservable inputs (including
       the Fund's own assumptions and judgment in determining the fair value of
       investments).

Inputs that are used in determining fair value of an investment may include
price information, credit data, volatility statistics, and other factors. These
inputs can be either observable or unobservable. The availability of observable
inputs can vary between investments, and is affected by various factors such as
the type of investment, and the volume and level of activity for that investment
or similar investments in the marketplace. The inputs will be considered by the
Fund Administrator, along with any other relevant factors in the calculation of
an investment's fair value. The Fund uses prices and inputs that are current as
of the measurement date, which may include periods of market dislocations.
During these periods, the availability of prices and inputs may be reduced for
many investments. This condition could cause an investment to be reclassified
between the various levels within the hierarchy.

Non-U.S. equity securities actively traded in foreign markets may be reflected
in Level 2 despite the availability of closing prices, because the Fund
evaluates and determines whether those closing prices reflect fair value at the
close of the New York Stock Exchange (NYSE) or require adjustment, as described
in Note 2 to the financial statements -- Valuation of securities.

Investments falling into the Level 3 category are primarily supported by quoted
prices from brokers and dealers participating in the market for those
investments. However, these may be classified as

- --------------------------------------------------------------------------------
          SELIGMAN COMMUNICATIONS AND INFORMATION FUND -- 2009 ANNUAL REPORT  23



PORTFOLIO OF INVESTMENTS (continued) -------------------------------------------

FAIR VALUE MEASUREMENTS (CONTINUED)




Level 3 investments due to lack of market transparency and corroboration to
support these quoted prices. Additionally, valuation models may be used as the
pricing source for any remaining investments classified as Level 3. These models
rely on one or more significant unobservable inputs and/or significant
assumptions by the Fund Administrator. Inputs used in a valuation model may
include, but are not limited to, financial statement analysis, discount rates
and estimated cash flows, and comparable company data.

The following table is a summary of the inputs used to value the Fund's
investments as of Dec. 31, 2009:

NOTES TO FINANCIAL STATEMENTS --------------------------------------------------

1. ORGANIZATION

Seligman Communications and Information Fund, Inc. (the Fund) is registered
under the Investment Company Act of 1940, as amended (the 1940 Act) as a
diversified, open-end management investment company and has one billion
authorized shares of capital stock. The Fund invests at least 80% of its net
assets in the securities of companies operating in the communications,
information and related industries.

The Fund offers Class A, Class B, Class C, Class I, Class R2, Class R3, Class R4
and Class R5 shares.

- -  Class A shares are offered with a front-end sales charge, which may be waived
   under certain circumstances.

- -  Class B shares may be subject to a contingent deferred sales charge (CDSC)
   and automatically convert to Class A shares one month after the completion of
   the eighth year of ownership if originally purchased in a RiverSource fund on
   or after May 21, 2005 or originally purchased in a Seligman fund on or after
   June 13, 2009. Class B shares originally purchased in a RiverSource fund
   prior to May 21, 2005 will convert to Class A shares in the ninth calendar
   year of ownership. Class B shares originally purchased in a Seligman fund
   prior to June 13, 2009 will convert to Class A shares in the month prior to
   the ninth year of ownership.

- -  Class C shares may be subject to a CDSC.

- -  Effective June 13, 2009, Class R and Class I* shares were redesignated as
   Class R2 and Class R5 shares, respectively. Class R2 and Class R5 shares are
   offered without a front-end sales charge or CDSC to qualifying institutional
   investors. Prior to June 13, 2009, Class R shares (redesignated to Class R2
   shares) charged a 1% CDSC on shares sold within one year of initial purchase.

- -  Class I*, Class R3 and Class R4 shares are offered without a front-end sales
   charge or CDSC to qualifying institutional investors. These share classes
   became available Aug. 3, 2009.

Effective May 16, 2008, Class D shares converted to Class C shares and as of
that date the Fund no longer offers Class D shares.

At Dec. 31, 2009, RiverSource Investments, LLC (RiverSource Investments or the
Investment Manager) and affiliated funds-of-funds in the RiverSource Family of
Funds owned 100% of Class I shares.


 *  All references within the report reflect the redesignated share classes
    (i.e. the Class I shares in existence on or before June 13, 2009 are
    reflected as Class R5 shares, and the Class I shares reflected are a new
    share class for the Fund.)

- --------------------------------------------------------------------------------
36  SELIGMAN COMMUNICATIONS AND INFORMATION FUND -- 2009 ANNUAL REPORT



- --------------------------------------------------------------------------------


All classes of shares have identical voting, dividend and liquidation rights.
Class specific expenses (e.g., distribution and service fees, transfer agency
fees, plan administration services fees) differ among classes. Income, expenses
(other than class specific expenses) and realized and unrealized gains or losses
on investments are allocated to each class of shares based upon its relative net
assets.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

ADOPTION OF NEW ACCOUNTING STANDARD
In June 2009, the Financial Accounting Standards Board (FASB) established the
FASB Accounting Standards Codification(TM )(Codification) as the single source
of authoritative accounting principles recognized by the FASB in the preparation
of financial statements in conformity with U.S. generally accepted accounting
principles (GAAP). The Codification supersedes existing non-grandfathered, non-
SEC accounting and reporting standards. The Codification did not change GAAP but
rather organized it into a hierarchy where all guidance within the Codification
carries an equal level of authority. The Codification became effective for
financial statements issued for interim and annual periods ending after Sept.
15, 2009. The Codification did not have an effect on the Fund's financial
statements.

USE OF ESTIMATES
Preparing financial statements that conform to U.S. generally accepted
accounting principles requires management to make estimates (e.g., on assets,
liabilities and contingent assets and liabilities) that could differ from actual
results.

VALUATION OF SECURITIES
All securities are valued at the close of business of the New York Stock
Exchange (NYSE). Securities traded on national securities exchanges or included
in national market systems are valued at the last quoted sales price. Debt
securities are generally traded in the over-the-counter market and are valued by
an independent pricing service using an evaluated bid. When market quotes are
not readily available, the pricing service, in determining fair values of debt
securities, takes into consideration such factors as current quotations by
broker/dealers, coupon, maturity, quality, type of issue, trading
characteristics, and other yield and risk factors it deems relevant in
determining valuations. Foreign securities are valued based on quotations from
the principal market in which such securities are normally traded. The
procedures adopted by the Fund's Board of Directors (the Board) generally
contemplate the use of fair valuation in the event that price quotations or
valuations are not readily available, price quotations or

- --------------------------------------------------------------------------------
          SELIGMAN COMMUNICATIONS AND INFORMATION FUND -- 2009 ANNUAL REPORT  37



NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------

valuations from other sources are not reflective of market value and thus deemed
unreliable, or a significant event has occurred in relation to a security or
class of securities (such as foreign securities) that is not reflected in price
quotations or valuations from other sources. A fair value price is a good faith
estimate of the value of a security at a given point in time.

Many securities markets and exchanges outside the U.S. close prior to the close
of the NYSE and therefore the closing prices for securities in such markets or
on such exchanges may not fully reflect events that occur after such close but
before the close of the NYSE, including significant movements in the U.S. market
after foreign exchanges have closed. Accordingly, in those situations,
Ameriprise Financial, Inc. (Ameriprise Financial), parent company of the
Investment Manager, as administrator to the Fund, will fair value foreign
securities pursuant to procedures adopted by the Board, including utilizing a
third party pricing service to determine these fair values. These procedures
take into account multiple factors, including movements in the U.S. securities
markets, to determine a good faith estimate that reasonably reflects the current
market conditions as of the close of the NYSE.

Short-term securities maturing in more than 60 days from the valuation date are
valued at the market price or approximate market value based on current interest
rates. Typically, those maturing in 60 days or less that originally had
maturities of more than 60 days at acquisition date are valued at amortized cost
using the market value on the 61st day before maturity. Short-term securities
maturing in 60 days or less at acquisition date are valued at amortized cost.
Amortized cost is an approximation of market value. Investments in money market
funds are valued at net asset value.

FOREIGN CURRENCY TRANSLATIONS
Securities and other assets and liabilities denominated in foreign currencies
are translated daily into U.S. dollars. Foreign currency amounts related to the
purchase or sale of securities and income and expenses are translated at the
exchange rate on the transaction date. The effect of changes in foreign exchange
rates on realized and unrealized security gains or losses is reflected as a
component of such gains or losses. In the Statement of Operations, net realized
gains or losses from foreign currency transactions, if any, may arise from sales
of foreign currency, closed forward contracts, exchange gains or losses realized
between the trade date and settlement date on securities transactions, and other
translation gains or losses on dividends, interest income and foreign
withholding taxes. At Dec. 31, 2009, foreign currency holdings were entirely
comprised of Taiwan dollars.


- --------------------------------------------------------------------------------
38  SELIGMAN COMMUNICATIONS AND INFORMATION FUND -- 2009 ANNUAL REPORT



- --------------------------------------------------------------------------------


REPURCHASE AGREEMENTS
The Fund may enter into repurchase agreements. Generally, securities received as
collateral subject to repurchase agreements are deposited with the Fund's
custodian and, pursuant to the terms of the repurchase agreement, must have an
aggregate market value greater than or equal to the repurchase price plus
accrued interest at all times. On a daily basis, the market value of securities
held as collateral for repurchase agreements is monitored to ensure the
existence of the proper level of collateral.

ILLIQUID SECURITIES
At Dec. 31, 2009, investments in securities included issues that are illiquid
which the Fund currently limits to 15% of net assets, at market value, at the
time of purchase. The aggregate value of such securities at Dec. 31, 2009 was
$3,812,499 representing 0.10% of net assets. Certain illiquid securities may be
valued, in good faith, by management at fair value according to procedures
approved by the Board. According to Board guidelines, certain unregistered
securities are determined to be liquid and are not included within the 15%
limitation specified above. Assets are liquid if they can be sold or disposed of
in the ordinary course of business within seven days at approximately the value
at which the asset is valued by the Fund.

GUARANTEES AND INDEMNIFICATIONS
Under the Fund's organizational documents, its officers and directors are
indemnified against certain liabilities arising out of the performance of their
duties to the Fund. In addition, certain of the Fund's contracts with its
service providers contain general indemnification clauses. The Fund's maximum
exposure under these arrangements is unknown since the amount of any future
claims that may be made against the Fund cannot be determined and the Fund has
no historical basis for predicting the likelihood of any such claims.

FEDERAL TAXES
The Fund's policy is to comply with Subchapter M of the Internal Revenue Code
that applies to regulated investment companies and to distribute substantially
all of its taxable income (which includes net short-term capital gains) to
shareholders. No provision for income or excise taxes is thus required.

Management of the Fund has concluded that there are no significant uncertain tax
positions that would require recognition in the financial statements. Generally,
the tax authorities can examine all the tax returns filed for the last three
years.

          SELIGMAN COMMUNICATIONS AND INFORMATION FUND -- 2009 ANNUAL REPORT  39



NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------

RECENT ACCOUNTING PRONOUNCEMENT
On Jan. 21, 2010, the FASB issued an Accounting Standards Update (the
amendment), Fair Value Measurements and Disclosures (Topic 820): Improving
Disclosures about Fair Value Measurements, which provides guidance on how
investment assets and liabilities are to be valued and disclosed. Specifically,
the amendment requires reporting entities to disclose the input and valuation
techniques used to measure fair value for both recurring and nonrecurring fair
value measurements for Level 2 or Level 3 positions. The amendment also requires
that transfers between all levels (including Level 1 and Level 2) be disclosed
on a gross basis (i.e., transfers out must be disclosed separately from
transfers in), and the reason(s) for the transfer. Additionally purchases,
sales, issuances and settlements must be disclosed on a gross basis in the Level
3 rollforward. The effective date of the amendment is for interim and annual
periods beginning after Dec. 15, 2009, however, the requirement to provide the
Level 3 activity for purchases, sales, issuances and settlements on a gross
basis will be effective for interim and annual periods beginning after Dec. 15,
2010. At this time the Fund is evaluating the implications of the amendment and
the impact to the financial statements.

DIVIDENDS TO SHAREHOLDERS
An annual dividend from net investment income, declared and paid at the end of
the calendar year, when available, is reinvested in additional shares of the
Fund at net asset value or payable in cash. Capital gains, when available, are
distributed along with the income dividend.

OTHER
Security transactions are accounted for on the date securities are purchased or
sold. Dividend income is recognized on the ex-dividend date and interest income,
including amortization of premium, market discount and original issue discount
using the effective interest method, is accrued daily.

3. INVESTMENTS IN DERIVATIVES

The Fund may invest in certain derivative instruments, which are transactions
whose values depend on or are derived from (in whole or in part) the value of
one or more other assets, such as securities, currencies, commodities or
indices. Such derivative instruments may be used to maintain cash reserves while
maintaining exposure to certain other assets, to offset anticipated declines in
values of investments, to facilitate trading, to reduce transaction costs, and
to pursue higher investment returns. The Fund may also use derivative
instruments to mitigate certain investment risks, such as foreign currency
exchange rate risk, interest rate risk, and credit risk.


- --------------------------------------------------------------------------------
40  SELIGMAN COMMUNICATIONS AND INFORMATION FUND -- 2009 ANNUAL REPORT



- --------------------------------------------------------------------------------


FORWARD FOREIGN CURRENCY CONTRACTS
The Fund may enter into forward foreign currency contracts in connection with
settling purchases or sales of securities, to hedge the currency exposure
associated with some or all of the Fund's securities or as part of its
investment strategy. A forward foreign currency contract is an agreement between
two parties to buy and sell a currency at a set price on a future date. The
market value of a forward foreign currency contract fluctuates with changes in
foreign currency exchange rates. Forward foreign currency contracts are marked
to market daily based upon foreign currency exchange rates from an independent
pricing service and the change in value is recorded as unrealized appreciation
or depreciation. The Fund will record a realized gain or loss when the forward
foreign currency contract is closed.

The risks of forward foreign currency contracts include movement in the values
of the foreign currencies relative to the U.S. dollar (or other foreign
currencies) and the possibility that the counterparty will not complete its
contractual obligation, which may be in excess of the amount, if any, reflected
in the Statement of Assets and Liabilities.

OPTION TRANSACTIONS
The Fund may buy and write options traded on any U.S. or foreign exchange, or in
the over-the-counter (OTC) market to produce incremental earnings, protect
gains, and facilitate buying and selling of securities for investments. The Fund
may also buy and sell put and call options and write covered call options on
portfolio securities. Options are contracts which entitle the holder to purchase
or sell securities or other financial instruments at a specified price, or in
the case of index options, to receive or pay the difference between the index
value and the strike price of the index option. Completion of options traded in
the OTC market depends upon the credit standing of the other party. Cash
collateral may be collected by the Fund to secure certain OTC options trades.
Cash collateral held by the Fund for such option trades must be returned to the
counterparty upon closure, exercise or expiration of the contract.

Option contracts purchased are recorded as investments and options contracts
written are recorded as liabilities of the Fund. Option contracts are valued
daily at the closing prices on their primary exchanges and unrealized
appreciation or depreciation is recorded. Option contracts, including OTC option
contracts, with no readily available market value are valued using quotations
obtained from independent brokers as of the close of the NYSE. The Fund will
realize a gain or loss when the option transaction expires or is exercised. When
options on debt securities or futures are exercised, the Fund will realize a
gain or loss. When other options are exercised, the proceeds on sales for a
written call option, the

- --------------------------------------------------------------------------------
          SELIGMAN COMMUNICATIONS AND INFORMATION FUND -- 2009 ANNUAL REPORT  41



NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------


purchase cost for a written put option or the cost of a security for a purchased
put or call option is adjusted by the amount of premium received or paid.

The risk in buying an option is that the Fund pays a premium whether or not the
option is exercised. The Fund also has the additional risk of being unable to
enter into a closing transaction if a liquid secondary market does not exist.
The risk in writing a call option is that the Fund gives up the opportunity for
profit if the market price of the security increases. The risk in writing a put
option is that the Fund may incur a loss if the market price of the security
decreases and the option is exercised. The Fund's maximum payout in the case of
written put option contracts represents the maximum potential amount of future
payments (undiscounted) that the Fund could be required to make as a guarantor
for written put options. For OTC options contracts, the transaction is also
subject to counterparty credit risk. The maximum payout amount may be offset by
the subsequent sale, if any, of assets obtained upon the exercise of the put
options by holders of the option contracts or proceeds received upon entering
into the contracts. At Dec. 31, 2009, and for the year then ended, the Fund had
no written or purchased options.

EFFECTS OF DERIVATIVE TRANSACTIONS ON THE FINANCIAL STATEMENTS
The following tables are intended to provide additional information about the
effect of derivatives on the financial statements of the Fund including: the
fair value of derivatives by risk category and the location of those fair values
in the Statement of Assets and Liabilities; the impact of derivative
transactions on the Fund's operations over the period including realized gains
or losses and unrealized gains or losses. The derivative schedules following the
Portfolio of Investments present additional information regarding derivative
instruments outstanding at the end of the period, if any.

FAIR VALUES OF DERIVATIVE INSTRUMENTS AT DEC. 31, 2009
At Dec. 31, 2009, the fund had no outstanding derivatives.

VOLUME OF DERIVATIVE ACTIVITY
FORWARD FOREIGN CURRENCY CONTRACTS
At Dec. 31, 2009, the Fund had no outstanding forward foreign currency
contracts. The monthly average gross notional amount for these contracts was
$300,000 for the year ended Dec. 31, 2009.

4. EXPENSES AND SALES CHARGES

INVESTMENT MANAGEMENT SERVICES FEES
Under an Investment Management Services Agreement, the Investment Manager
determines which securities will be purchased, held or sold. Effective June 29,
2009, the management fee is equal to a percentage of the Fund's average daily
net assets that declines from 0.855% to 0.725% as the Fund's net assets
increase. Prior to June 29, 2009, the Investment Manager received an annual fee,
equal to a percentage of the Fund's average daily net assets that declined from
0.90% to 0.75% as the Fund's net assets increased. The management fee for the
year ended Dec. 31, 2009 was 0.87% of the Fund's average daily net assets. The
reduction in the investment management services fee schedule on June 29, 2009 is
related to the elimination of the administrative portion of the management fee
that is now being charged separately to the Fund through the Administrative
Services Agreement with Ameriprise Financial. See Administrative services fees
below for more information.

ADMINISTRATIVE SERVICES FEES
Under an Administrative Services Agreement, effective June 29, 2009, the Fund
pays Ameriprise Financial an annual fee for administration and accounting
services equal to a percentage of the Fund's average daily net assets that
declines from 0.06% to 0.03% as the Fund's net assets increase. The fee for the
period from June 29, 2009 through Dec. 31, 2009 was 0.03% of the Fund's average

- --------------------------------------------------------------------------------
          SELIGMAN COMMUNICATIONS AND INFORMATION FUND -- 2009 ANNUAL REPORT  43



NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------

daily net assets. Prior to June 29, 2009, Ameriprise Financial administered
certain aspects of the Fund's business and other affairs for no additional fee.
The fees payable under the Administrative Services Agreement beginning on June
29, 2009 are offset by corresponding decreases in the investment management fees
charged to the Fund and the elimination of separate fees that were previously
payable to State Street Bank and Trust Company, in its capacity as the Fund's
prior administrative agent.

OTHER FEES
Other expenses are for, among other things, certain expenses of the Fund or the
Board including: Fund boardroom and office expense, employee compensation,
employee health and retirement benefits, and certain other expenses. Payment of
these Fund and Board expenses is facilitated by a company providing limited
administrative services to the Fund and the Board. For the year ended Dec. 31,
2009, other expenses paid to this company were $15,617.

COMPENSATION OF BOARD MEMBERS
Under a Deferred Compensation Plan (the Plan), the board members who are not
"interested persons" of the Fund under the 1940 Act may defer receipt of their
compensation. Deferred amounts are treated as though equivalent dollar amounts
had been invested in shares of the Fund or other funds in the RiverSource Family
of Funds. The Fund's liability for these amounts is adjusted for market value
changes and remains in the funds until distributed in accordance with the Plan.

TRANSFER AGENCY FEES
Effective June 15, 2009, under a Transfer Agency Agreement, RiverSource Service
Corporation (the Transfer Agent) maintains Fund shareholder accounts and records
and provides Fund shareholder services. Under the Agreement, each Fund pays the
Transfer Agent an annual account-based fee at a rate equal to $19.50 for Class
A, $20.50 for Class B and $20.00 for Class C for this service. The Transfer
Agent also charges an annual fee of $3 per account serviced directly by the Fund
or its designated agent for Class A, Class B and Class C shares. The Fund also
pays the Transfer Agent an annual asset-based fee at a rate of 0.05% of the
Fund's average daily net assets attributable to Class R2, Class R3, Class R4 and
Class R5 shares. The Transfer Agent charges an annual fee of $5 per inactive
account, charged on a pro rata basis for the 12 month period from the date the
account becomes inactive. These fees are included in the transfer agency fees in
the Statement of Operations.

Prior to June 15, 2009, Seligman Data Corp. (SDC), owned by six associated
investment companies, provided shareholder servicing and transfer agency
services to the Fund, as well as certain other Seligman funds. In January 2009,
the Board approved the Fund's termination of the shareholder servicing and

- --------------------------------------------------------------------------------
44  SELIGMAN COMMUNICATIONS AND INFORMATION FUND -- 2009 ANNUAL REPORT



- --------------------------------------------------------------------------------



transfer agency relationship with SDC and the engagement of RiverSource Service
Corporation to provide shareholder servicing and transfer agency services. As a
result of the Board's termination of the shareholder servicing and transfer
agency relationship with SDC (which was SDC's sole business), SDC has exited the
transfer agent business, effective June 15, 2009.

For the period from Jan. 1, 2009 to June 15, 2009, SDC charged the Fund
$3,591,869 for shareholder account and transfer agent services in accordance
with a methodology approved by the Fund's Board. Class R5 shares received more
limited shareholder services than the Fund's other classes of shares. SDC did
not allocate to Class R5 the costs of any of its departments that did not
provide services to the Class R5 shareholders. Costs of SDC directly
attributable to the other classes of the Fund were charged to those classes in
proportion to their relative net asset values. Costs directly attributable to
Class R5 shares were charged to Class R5. The remaining charges were allocated
to all classes by SDC pursuant to a formula based on their net assets,
shareholder transaction volumes and number of shareholder accounts.

In connection with the termination of the Fund's relationship with SDC, the Fund
incurred certain non-recurring charges, including charges relating to the
remaining periods of SDC's leases (the Non-Recurring Charges). These Non-
Recurring Charges were incurred over a period from Jan. 28, 2009 to June 12,
2009, and amounted to $3,764,056 or 0.13% of the Fund's average daily net assets
for the year ended Dec. 31, 2009. These Non-Recurring Charges are included in
transfer agency fees in the Statement of Operations.

The Fund and certain other associated investment companies (together, the
Guarantors) have severally but not jointly guaranteed the performance and
observance of all the terms and conditions of a lease entered into by SDC,
including the payment of rent by SDC (the Guaranty). The lease and the Guaranty
expire in January 2019. At Dec. 31, 2009, the Fund's total potential future
obligation over the life of the Guaranty is $4,051,251. The liability remaining
at Dec. 31, 2009 for Non-Recurring Charges amounted to $2,078,084 and is
included within accrued transfer agency fees in the Statement of Assets and
Liabilities.

PLAN ADMINISTRATION SERVICES FEES
Under a Plan Administration Services Agreement, effective June 15, 2009, the
Fund pays the Transfer Agent an annual fee at a rate of 0.25% of the Fund's
average daily net assets attributable to Class R2, Class R3 and Class R4 shares
for the provision of various administrative, recordkeeping, communication and
educational services.


- --------------------------------------------------------------------------------
          SELIGMAN COMMUNICATIONS AND INFORMATION FUND -- 2009 ANNUAL REPORT  45



NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------

DISTRIBUTION FEES
The Fund has an agreement with RiverSource Fund Distributors, Inc. (the
Distributor) for distribution and shareholder services. Under a Plan and
Agreement of Distribution pursuant to Rule 12b-1, the Fund pays a fee at an
annual rate of up to 0.25% of the Fund's average daily net assets attributable
to Class A and Class R3 shares, a fee at an annual rate of up to 0.50% of the
Fund's average daily net assets attributable to Class R2 shares and a fee at an
annual rate of up to 1.00% of the Fund's average daily net assets attributable
to Class B and Class C shares. For Class B and Class C shares, of the 1.00% fee,
up to 0.75% was reimbursed for distribution expenses.

The amount of distribution expenses incurred by the Distributor and not yet
reimbursed (unreimbursed expense) was approximately $1,333,000 and $20,771,000
for Class B and Class C shares, respectively. These amounts are based on the
most recent information available as of Oct. 31, 2009, and may be recovered from
future payments under the distribution plan or CDSC. To the extent the
unreimbursed expense has been fully recovered, the distribution fee is reduced.

SALES CHARGES
Sales charges, including front-end and CDSCs, received by the Distributor for
distributing Fund shares were $3,217,828 for Class A, $230,474 for Class B and
$39,161 for Class C for the year ended Dec. 31, 2009. Effective June 13, 2009,
the 1% CDSC was eliminated for Class R2 shares.

5. SECURITIES TRANSACTIONS

Cost of purchases and proceeds from sales of securities (other than short-term
obligations) aggregated $4,044,782,726 and $4,039,460,061, respectively, for the
year ended Dec. 31, 2009. Realized gains and losses are determined on an
identified cost basis.

6. CAPITAL SHARE TRANSACTIONS

Transactions in shares of capital stock for the periods indicated are as

NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------

7. LENDING OF PORTFOLIO SECURITIES

Effective May 15, 2009, the Fund has entered into a Master Securities Lending
Agreement (the Agreement) with JPMorgan Chase Bank, National Association
(JPMorgan). The Agreement authorizes JPMorgan as lending agent to lend
securities to authorized borrowers in order to generate additional income on
behalf of the Fund. Pursuant to the Agreement, the securities loaned are secured
by cash or U.S. government securities equal to at least 100% of the market value
of the loaned securities. Any additional collateral required to maintain those
levels due to market fluctuations of the loaned securities is delivered the
following business day. Cash collateral received is invested by the lending
agent on behalf of the Fund into authorized investments pursuant to the
Agreement. The investments made with the cash collateral are listed in the
Portfolio of Investments. The values of such investments and any uninvested cash
collateral balance are disclosed in the Statement of Assets and Liabilities
along with the related obligation to return the collateral upon the return of
the securities loaned. At Dec. 31, 2009, securities valued at $523,221,578 were
on loan, secured by cash collateral of $543,858,831 invested in short-term
securities or in cash equivalents.

Risks of delay in recovery of securities or even loss of rights in the
securities may occur should the borrower of the securities fail financially.
Risks may also arise to the extent that the value of the securities loaned
increases above the value of the collateral received. JPMorgan will indemnify
the Fund from losses resulting from a borrower's failure to return a loaned
security when due. Such indemnification does not extend to losses associated
with declines in the value of cash collateral investments. Loans are subject to
termination by the Funds or the borrower at any time, and are, therefore, not
considered to be illiquid investments.

Pursuant to the Agreement, the Fund receives income for lending its securities
either in the form of fees or by earning interest on invested cash collateral,
net of negotiated rebates paid to borrowers and fees paid to the lending agent
for services provided and any other securities lending expenses. Net income of
$569,338 earned from securities lending from June 26, 2009 through Dec. 31, 2009
is included in the Statement of Operations. The Fund also continues to earn
interest and dividends on the securities loaned.

8. AFFILIATED MONEY MARKET FUND

The Fund may invest its daily cash balance in RiverSource Short-Term Cash Fund,
a money market fund established for the exclusive use of the funds in the
RiverSource Family of Funds and other institutional clients of RiverSource

- --------------------------------------------------------------------------------
48  SELIGMAN COMMUNICATIONS AND INFORMATION FUND -- 2009 ANNUAL REPORT



- --------------------------------------------------------------------------------



Investments. The cost of the Fund's purchases from sales of shares of
RiverSource Short-Term Cash Fund aggregated $1,388,461,661 and $1,168,127,855,
respectively, for the year ended Dec. 31, 2009. The income distributions
received with respect to the Fund's investment in RiverSource Short-Term Cash
Fund can be found in the Statement of Operations and the Fund's invested balance
in RiverSource Short-Term Cash Fund at Dec. 31, 2009, can be found in the
Portfolio of Investments.

9. BANK BORROWINGS

The Fund has entered into a revolving credit facility with a syndicate of banks
led by JPMorgan Chase Bank, N.A. (the Administrative Agent), whereby the Fund
may borrow for the temporary funding of shareholder redemptions or for other
temporary or emergency purposes. The credit facility became effective on Oct.
15, 2009, replacing the prior credit facilities. The credit facility agreement,
which is a collective agreement between the Fund and certain other funds in the
RiverSource Family of Funds, severally and not jointly, permits collective
borrowings up to $300 million. The borrowers shall have the right, upon written
notice to the Administrative Agent to request an increase of up to $200 million
in the aggregate amount of the credit facility from new or existing lenders,
provided that the aggregate amount of the credit facility shall at no time
exceed $500 million. Participation in such increase by any existing lender shall
be at such lender's sole discretion. Interest is charged to the Fund based on
its borrowings at a rate equal to the sum of the federal funds rate plus (A)
1.25% per annum plus (B) if one-month LIBOR exceeds the federal funds rate, the
amount of such excess. Each borrowing under the credit facility matures no later
than 60 days after the date of borrowing. The Fund also pays a commitment fee
equal to its pro rata share of the amount of the credit facility at a rate of
0.10% per annum, in addition to an upfront fee equal to its pro rata share of
0.04% of the amount of the credit facility.

For the period from June 17, 2009 through Oct. 15, 2009, the credit facility
agreement, which was a collective agreement between the Fund and certain other
funds in the RiverSource Family of Funds, severally and not jointly, permitted
collective borrowings up to $475 million. Interest was charged to the Fund based
on its borrowings at a rate equal to the federal funds rate plus 0.75%. The Fund
also paid a commitment fee equal to its pro rata share of the amount of the
credit facility at a rate of 0.06% per annum.

Prior to June 17, 2009, the Fund participated in a joint $200 million committed
line of credit that was shared by substantially all funds in the Seligman Group
of Investment Companies. The Board had limited the Fund's borrowings to 10% of

- --------------------------------------------------------------------------------
          SELIGMAN COMMUNICATIONS AND INFORMATION FUND -- 2009 ANNUAL REPORT  49



NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------


its net assets. Borrowings pursuant to the credit facility were subject to
interest at a rate equal to the overnight federal funds rate plus 0.50%. The
Fund incurred a commitment fee of 0.12% per annum on its share of the unused
portion of the credit facility. The credit facility may have been drawn upon
only for temporary purposes and was subject to certain other customary
restrictions. The Fund had no borrowings during the year ended Dec. 31, 2009.

10. PROCEEDS FROM REGULATORY SETTLEMENTS

In May 2009, as a result of a settlement of an administrative proceeding brought
by the Securities and Exchange Commission against an unaffiliated third party
relating to market timing and/or late trading of mutual funds, the Fund received
$271,302, which represented the Fund's portion of the proceeds from the
settlement (the Fund was not a party to the proceeding). The proceeds received
by the Fund were recorded as an increase to additional paid-in capital.

In March 2009, without admitting or denying any violations of law or wrongdoing,
J&W Seligman & Co., Incorporated (Seligman), Seligman Advisors, Inc., Seligman
Data Corp. and Brian T. Zino entered into a stipulation of settlement with the
Office of the Attorney General of the State of New York (NYAG) and settled the
claims made by the NYAG. Under the terms of the settlement, Seligman paid $7.7
million to the Fund. The proceeds received by the Fund were recorded as an
increase to additional paid-in capital.

11. FEDERAL TAX INFORMATION

Net investment income (loss) and net realized gains (losses) may differ for
financial statement and tax purposes primarily because of foreign currency
transactions, post-October losses and losses deferred due to wash sales. The
character of distributions made during the year from net investment income or
net realized gains may differ from their ultimate characterization for federal
income tax purposes. Also, due to the timing of dividend distributions, the
fiscal year in which amounts are distributed may differ from the year that the
income or realized gains (losses) were recorded by the Fund.

In the Statement of Assets and Liabilities, as a result of permanent book-to-tax
differences, accumulated net investment loss has been decreased by $38,980,395
and accumulated net realized loss has been decreased by $7,416,229 resulting in
a net reclassification adjustment to decrease paid-in capital by $46,396,624.


- --------------------------------------------------------------------------------
50  SELIGMAN COMMUNICATIONS AND INFORMATION FUND -- 2009 ANNUAL REPORT



- --------------------------------------------------------------------------------


For the years ended 2009 and 2008 there were no distributions.

At Dec. 31, 2009, the components of distributable earnings on a tax basis are as
follows:

<Table>
                                               
Undistributed ordinary income                     $          --
Undistributed accumulated long-term gain          $          --
Accumulated realized loss                         $(207,486,080)
Unrealized appreciation (depreciation)            $ 224,065,250
</Table>


For federal income tax purposes, the Fund had a capital loss carry-over of
$207,486,080 at Dec. 31, 2009, that if not offset by capital gains will expire
as follows:


<Table>
<Caption>
    2011           2016           2017
                        
$12,308,398    $97,889,818    $97,287,864
</Table>


It is unlikely the Board will authorize a distribution of any net realized
capital gains until the available capital loss carry-over has been offset or
expires. There is no assurance that the Fund will be able to utilize all of its
capital loss carry-over before it expires.

12. RISKS RELATING TO CERTAIN INVESTMENTS

CONCENTRATION RISK
The Fund concentrates its investments in companies in the communications,
information and related industries. Therefore, the Fund may be susceptible to
factors affecting these industries and the Fund's net asset value may fluctuate
more than a fund that invests in a wider range of industries. In addition, the
rapid pace of change within many of these industries tends to create a more
volatile operating environment than in other industries.

13. SUBSEQUENT EVENTS

Management has evaluated Fund related events and transactions that occurred
during the period from the date of the Statement of Assets and Liabilities
through Feb. 22, 2010, the date of issuance of the Fund's financial statements.
There were no events or transactions that occurred during the period that
materially impacted the amounts or disclosures in the Fund's financial
statements.

14. INFORMATION REGARDING PENDING AND SETTLED LEGAL PROCEEDINGS

In June 2004, an action captioned John E. Gallus et al. v. American Express
Financial Corp. and American Express Financial Advisors Inc. was filed in the

- --------------------------------------------------------------------------------
          SELIGMAN COMMUNICATIONS AND INFORMATION FUND -- 2009 ANNUAL REPORT  51



NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------


United States District Court for the District of Arizona. The plaintiffs allege
that they are investors in several American Express Company (now known as
RiverSource) mutual funds and they purport to bring the action derivatively on
behalf of those funds under the Investment Company Act of 1940. The plaintiffs
allege that fees allegedly paid to the defendants by the funds for investment
advisory and administrative services are excessive. The plaintiffs seek remedies
including restitution and rescission of investment advisory and distribution
agreements. The plaintiffs voluntarily agreed to transfer this case to the
United States District Court for the District of Minnesota (the District Court).
In response to defendants' motion to dismiss the complaint, the District Court
dismissed one of plaintiffs' four claims and granted plaintiffs limited
discovery. Defendants moved for summary judgment in April 2007. Summary judgment
was granted in the defendants' favor on July 9, 2007. The plaintiffs filed a
notice of appeal with the Eighth Circuit Court of Appeals (the Eighth Circuit)
on August 8, 2007. On April 8, 2009, the Eighth Circuit reversed summary
judgment and remanded to the District Court for further proceedings. On August
6, 2009, defendants filed a writ of certiorari with the U.S. Supreme Court,
asking the U.S. Supreme Court to stay the District Court proceedings while the
U.S. Supreme Court considers and rules in a case captioned Jones v. Harris
Associates, which involves issues of law similar to those presented in the
Gallus case.

In December 2005, without admitting or denying the allegations, American Express
Financial Corporation (AEFC, which is now known as Ameriprise Financial, Inc.
(Ameriprise Financial)), entered into settlement agreements with the Securities
and Exchange Commission (SEC) and Minnesota Department of Commerce (MDOC)
related to market timing activities. As a result, AEFC was censured and ordered
to cease and desist from committing or causing any violations of certain
provisions of the Investment Advisers Act of 1940, the Investment Company Act of
1940, and various Minnesota laws. AEFC agreed to pay disgorgement of $10 million
and civil money penalties of $7 million. AEFC also agreed to retain an
independent distribution consultant to assist in developing a plan for
distribution of all disgorgement and civil penalties ordered by the SEC in
accordance with various undertakings detailed at
http://www.sec.gov/litigation/admin/ia-2451.pdf. Ameriprise Financial and its
affiliates have cooperated with the SEC and the MDOC in these legal proceedings,
and have made regular reports to the RiverSource Funds' Boards of
Directors/Trustees.

On November 7, 2008, RiverSource Investments, LLC, a subsidiary of Ameriprise
Financial, Inc., acquired J. & W. Seligman & Co. Incorporated (Seligman). In
late 2003, Seligman conducted an extensive internal review

- --------------------------------------------------------------------------------
52  SELIGMAN COMMUNICATIONS AND INFORMATION FUND -- 2009 ANNUAL REPORT



- --------------------------------------------------------------------------------



concerning mutual fund trading practices. Seligman's review, which covered the
period 2001-2003, noted one arrangement that permitted frequent trading in
certain open-end registered investment companies managed by Seligman (the
Seligman Funds); this arrangement was in the process of being closed down by
Seligman before September 2003. Seligman identified three other arrangements
that permitted frequent trading, all of which had been terminated by September
2002. In January 2004, Seligman, on a voluntary basis, publicly disclosed these
four arrangements to its clients and to shareholders of the Seligman Funds.
Seligman also provided information concerning mutual fund trading practices to
the SEC and the Office of the Attorney General of the State of New York (NYAG).

In September 2006, the NYAG commenced a civil action in New York State Supreme
Court against Seligman, Seligman Advisors, Inc. (now known as RiverSource Fund
Distributors, Inc.), Seligman Data Corp. and Brian T. Zino (collectively, the
Seligman Parties), alleging, in substance, that the Seligman Parties permitted
various persons to engage in frequent trading and, as a result, the prospectus
disclosure used by the registered investment companies then managed by Seligman
was and had been misleading. The NYAG included other related claims and also
claimed that the fees charged by Seligman to the Seligman Funds were excessive.
On March 13, 2009, without admitting or denying any violations of law or
wrongdoing, the Seligman Parties entered into a stipulation of settlement with
the NYAG and settled the claims made by the NYAG. Under the terms of the
settlement, Seligman paid $11.3 million to four Seligman Funds. This settlement
resolved all outstanding matters between the Seligman Parties and the NYAG. In
addition to the foregoing matter, the New York staff of the SEC indicated in
September 2005 that it was considering recommending to the Commissioners of the
SEC the instituting of a formal action against Seligman and Seligman Advisors,
Inc. relating to frequent trading in the Seligman Funds. Seligman responded to
the staff in October 2005 that it believed that any action would be both
inappropriate and unnecessary, especially in light of the fact that Seligman had
previously resolved the underlying issue with the Independent Directors of the
Seligman Funds and made recompense to the affected Seligman Funds. There have
been no further developments with the SEC on this matter.

Ameriprise Financial and certain of its affiliates have historically been
involved in a number of legal, arbitration and regulatory proceedings, including
routine litigation, class actions, and governmental actions, concerning matters
arising in connection with the conduct of their business activities. Ameriprise
Financial believes that the Funds are not currently the subject of, and that
neither Ameriprise Financial nor any of its affiliates are the subject of, any
pending

- --------------------------------------------------------------------------------
          SELIGMAN COMMUNICATIONS AND INFORMATION FUND -- 2009 ANNUAL REPORT  53



NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------


legal, arbitration or regulatory proceedings that are likely to have a material
adverse effect on the Funds or the ability of Ameriprise Financial or its
affiliates to perform under their contracts with the Funds. Ameriprise Financial
is required to make 10-Q, 10-K and, as necessary, 8-K filings with the
Securities and Exchange Commission on legal and regulatory matters that relate
to Ameriprise Financial and its affiliates. Copies of these filings may be
obtained by accessing the SEC website at www.sec.gov.

There can be no assurance that these matters, or the adverse publicity
associated with them, will not result in increased fund redemptions, reduced
sale of fund shares or other adverse consequences to the Funds. Further,
although we believe proceedings are not likely to have a material adverse effect
on the Funds or the ability of Ameriprise Financial or its affiliates to perform
under their contracts with the Funds, these proceedings are subject to
uncertainties and, as such, we are unable to estimate the possible loss or range
of loss that may result. An adverse outcome in one or more of these proceedings
could result in adverse judgments, settlements, fines, penalties or other relief
that could have a material adverse effect on the consolidated financial
condition or results of operations of Ameriprise Financial.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM ------------------------

TO THE BOARD OF DIRECTORS AND SHAREHOLDERS OF
SELIGMAN COMMUNICATIONS AND INFORMATION FUND, INC.:


We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of Seligman Communications and Information Fund,
Inc. (the Fund) as of December 31, 2009, and the related statements of
operations, changes in net assets, and the financial highlights for the year
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 statement of changes in net assets and financial highlights of the
Fund for the periods presented through December 31, 2008, were audited by other
auditors whose report dated February 27, 2009, expressed an unqualified opinion
on those financial statements and financial highlights.

We conducted our audit in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Fund's internal control over financial
reporting. Our 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 and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of December 31, 2009, by correspondence with the custodian
and brokers, or by other appropriate auditing procedures where replies from
brokers were not received. We believe that our audit provides a reasonable basis
for our opinion.

the financial highlights for the year then ended, in conformity with U.S.
