Dear Stockholders,

We are pleased to present the semiannual stockholder report for Seligman Premium

results, portfolio of investment and financial statements as of June 30, 2010.

The Fund's common stock decreased 10.23% (excluding sales charge) based on net
asset value and 5.18% based on market price, for the six months ended June 30,
2010. The Fund outperformed its benchmark, the S&P North American Technology
Sector Index, which declined 10.39% during the same period.

During the six month period, the Fund paid two distributions, in accordance with

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.

FAIR VALUE MEASUREMENTS (CONTINUED)




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 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 June 30, 2010:

FINANCIAL HIGHLIGHTS -----------------------------------------------------------

The Fund's financial highlights are presented below. Per share operating
performance data is designed to allow investors to trace the operating
performance, on a per Common share basis, from the beginning net asset value to
the ending net asset value, so that investors can understand what effect the
individual items have on their investment, assuming it was held throughout the
period. Generally, the per share amounts are derived by converting the actual
dollar amounts incurred for each item, as disclosed in the financial statements,
to their equivalent per Common share amounts, using average Common shares
outstanding during the period.

Total return measures the Fund's performance assuming that investors purchased
Fund shares at market price or net asset value as of the beginning of the
period, reinvested all their distributions, and then sold their shares at the
closing market price or net asset value on the last day of the period. The
computations do not reflect taxes or any sales commissions investors may incur
in purchasing or selling Fund shares and taxes investors may incur on
distributions or on the sale of Fund shares. Total returns are not annualized
for periods of less than one year.

NOTES TO FINANCIAL STATEMENTS --------------------------------------------------
(UNAUDITED AS OF JUNE 30, 2010)

1. ORGANIZATION

Seligman Premium Technology Growth Fund, Inc. (the Fund) is registered with the
Securities and Exchange Commission under the Investment Company Act of 1940, as
amended (the 1940 Act) as a non-diversified, closed-end management investment
company. The Fund was incorporated under the laws of the State of Maryland on
Sept. 3, 2009, and commenced investment operations on Nov. 30, 2009. The Fund
had no investment operations prior to Nov. 30, 2009 other than those relating to
organizational matters and the sale to Columbia Management Investment Advisers,
LLC (formerly RiverSource Investments, LLC) (the Investment Manager) of 5,250
common shares (Common Stock) at a cost of $100,275 on Oct. 14, 2009. As of Dec.
31, 2009, the Fund issued 14,300,000 shares of Common Stock, including
13,100,000 shares of Common Stock in its initial public offering and 1,200,000
shares of Common Stock purchased by the Fund's underwriters pursuant to an over-
allotment option granted to the underwriters in connection with the initial
public offering. On Jan. 13, 2010, the Fund's underwriters purchased an
additional 545,000 shares of Common Stock pursuant to the over-allotment option,
resulting in a total of 14,845,000 shares of Common Stock issued by the Fund in
its initial public offering, including shares purchased by the underwriters
pursuant to the over-allotment option. With this closing of this additional
purchase of Common Stock, the Fund's total raise-up in its initial public
offering was an aggregate of $296.9 million. The Fund has one billion authorized
shares of Common Stock which trades on the New York Stock Exchange (NYSE) under
the symbol "STK".

The Fund's investment objectives are to seek growth of capital and current
income. Under normal market conditions, the Fund's investment program will
consist primarily of (i) investing in a portfolio of equity securities of
technology and technology-related companies that seeks to exceed the total
return, before fees and expenses, of the S&P North American Technology Sector
Index(R) and (ii) writing call options on the NASDAQ 100 Index(R), an unmanaged
index that includes the largest and most active non-financial domestic and
international companies listed on the Nasdaq Stock Market, or its exchange-
traded fund equivalent (the NASDAQ 100) on a month-to-month basis, with an
aggregate notional amount typically ranging from 25% to 90% of the underlying
value of the Fund's holdings of Common Stock. The Fund expects to generate
current income from premiums received from writing call options on the NASDAQ
100. The Fund may also buy or write other call and put options on securities,
indices, ETFs and market baskets of securities to generate additional income or
return or to provide the portfolio with downside protection as further described
below in Note 3 to the financial statements - Investment in Derivatives.


--------------------------------------------------------------------------------
18  SELIGMAN PREMIUM TECHNOLOGY GROWTH FUND -- 2010 SEMIANNUAL REPORT



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


The Fund currently has outstanding Common Stock. Each outstanding share of
Common Stock entitles the holder thereof to one vote on all matters submitted to
a vote of the Common Stockholders, including the election of directors. Because
the Fund has no other classes or series of stock outstanding, Common Stock
possesses exclusive voting power. All of the Fund's shares of Common Stock have
equal dividend, liquidation, voting and other rights. The Fund's Common
Stockholders have no preference, conversion, redemption, exchange, sinking fund,
or appraisal rights and have no preemptive rights to subscribe for any of the
Fund's securities.

Although the Fund has no current intention to do so, the Fund is authorized and
reserves the flexibility to use leverage to increase its investments or for
other management activities through the issuance of preferred shares (Preferred
Stock) and/or borrowings. The costs of issuing Preferred Stock and/or a
borrowing program would be borne by holders of Common Stock (Common
Stockholders) and consequently would result in a reduction of net asset value of
Common Stock.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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 each business day of the NYSE.
Securities traded on national securities exchanges or included in national
market systems are valued at the last quoted sales price from the primary
exchange. 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 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

--------------------------------------------------------------------------------
           SELIGMAN PREMIUM TECHNOLOGY GROWTH FUND -- 2010 SEMIANNUAL REPORT  19



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

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. The fair value of a security is
likely to be different from the quoted or published price, if available.

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 61(st) 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.

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

--------------------------------------------------------------------------------
20  SELIGMAN PREMIUM TECHNOLOGY GROWTH FUND -- 2010 SEMIANNUAL REPORT



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


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 income taxable (which includes net short-term capital gains) to
Common Stockholders. 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.

FOREIGN CAPITAL GAINS TAXES
Realized gains in certain countries may be subject to foreign taxes at the fund
level, at rates ranging from approximately 10% to 15%. The Fund pays such
foreign taxes on net realized gains at the appropriate rate for each
jurisdiction.

DIVIDENDS TO STOCKHOLDERS
Under its level rate distribution policy, the Fund intends to make quarterly
distributions to Common Stockholders at a rate that reflects the past and
projected performance of the Fund. The Fund expects to receive all or some of
its current income and gains from the following sources: (i) dividends received
by the Fund that are paid on the equity and equity-related securities in its
portfolio; and (ii) capital gains (short-term and long-term) from option
premiums and the sale of portfolio securities. Distributions would be made only
after paying dividends on Preferred Stock, if any have been issued. It is
possible that the Fund's distributions will at times exceed the earnings and
profits of the Fund and therefore all or a portion of such distributions may
constitute a return of capital as described below. A return of capital is a
return of a portion of an investor's original investment. A return of capital is
not taxable, but it reduces a Stockholder's tax basis in his or her shares, thus
reducing any loss or increasing any gain on a subsequent taxable disposition by
the Stockholder of his or her shares. Distributions may vary, and the Fund's
distribution rate will depend on a number of factors, including the net earnings
on the Fund's portfolio investments and the rate at which such net earnings
change as a result of changes in the timing of, and rates at which, the Fund
receives income from the sources described above. The net investment income of
the Fund consists of all income

--------------------------------------------------------------------------------
           SELIGMAN PREMIUM TECHNOLOGY GROWTH FUND -- 2010 SEMIANNUAL REPORT  21



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

(other than net short-term and long-term capital gains) less all expenses of the
Fund.

As portfolio and market conditions change, the rate of dividends on the Common
Stock and the Fund's distribution policy could change. Over time, the Fund will
distribute all of its net investment income and net short-term capital gains. In
addition, at least annually, the Fund intends to distribute any net capital gain
(which is the excess of net long-term capital gain over net short-term capital
loss) or, alternatively, to retain all or a portion of the year's net capital
gain and pay federal income tax on the retained gain. The 1940 Act currently
limits the number of times the Fund may distribute long-term capital gains in
any tax year (unless and until it receives an exemptive order), which may
increase the variability of the Fund's distributions. The Board reserves the
right to change the dividend policy from time to time.

Dividends and other distributions to Stockholders are recorded on ex-dividend
dates.

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

3. INVESTMENT 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. The Fund uses a rules-based call option writing strategy on the NASDAQ
100 on a month-to-month basis, with an aggregate notional amount typically
ranging from 25% to 90% of the underlying value of the Fund's holdings of common
stock (the Rules-based Option Strategy). In addition to the Rules-based Option
Strategy, the Fund may write additional calls with aggregate notional amounts of
up to 25% of the value of the Fund's holdings in common stocks (to a maximum of
90% when aggregated with the call options written pursuant to the Rules-based
Option Strategy) when call premiums are attractive relative to the risk of the
price of the NASDAQ 100. The Fund may also close (or buy back) a written call
option if the Investment Manager believes that a substantial amount of the
premium (typically, 70% or more) to be received by the Fund has been captured
before exercise, potentially reducing the call position to 0% of total equity
until additional calls are written.


--------------------------------------------------------------------------------
22  SELIGMAN PREMIUM TECHNOLOGY GROWTH FUND -- 2010 SEMIANNUAL REPORT



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


The Fund may also seek to provide downside protection by purchasing puts on the
NASDAQ 100 when premiums on these options are considered by the Investment
Manager to be low and, therefore, attractive relative to the downside protection
provided.

The Fund may also buy or write other call and put options on securities,
indices, ETFs and market baskets of securities to generate additional income or
return or to provide the portfolio with downside protection. In this regard,
options may include writing "in-" or "out-of-the-money" put options or buying or
selling options in connection with closing out positions prior to expiration of
any options. However, the Fund does not intend to write "naked" call options on
individual stocks (i.e., selling a call option on an individual security not
owned by the Fund) other than in connection with implementing the options
strategies with respect to the NASDAQ 100. The put and call options purchased,
sold or written by the Fund may be exchange-listed or over-the-counter (OTC).

Investments in derivative instruments may expose the Fund to certain additional
risks, including those detailed below.

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. At June 30, 2010, the Fund had no
outstanding forward foreign currency contracts.

OPTION TRANSACTIONS
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

--------------------------------------------------------------------------------
           SELIGMAN PREMIUM TECHNOLOGY GROWTH FUND -- 2010 SEMIANNUAL REPORT  23



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

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 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 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. 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. The maximum payout amount
was $6,727,100 at June 30, 2010.

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.

4. EXPENSES

INVESTMENT MANAGEMENT SERVICES FEES
Under an Investment Management Services Agreement between the Investment Manager
and the Fund (the Management Agreement), the Investment Manager determines on
behalf of the Fund which securities will be purchased, held or sold. Under the
Management Agreement, the Fund will pay the Investment Manager a management fee,
payable on a monthly basis, at an annual rate equal to 1.00% of the Fund's
average daily Managed Assets. "Managed Assets" means

--------------------------------------------------------------------------------
           SELIGMAN PREMIUM TECHNOLOGY GROWTH FUND -- 2010 SEMIANNUAL REPORT  25



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

the net asset value of the Fund's outstanding Common Stock plus the liquidation
preference of any issued and outstanding Preferred Stock of the Fund and the
principal amount of any borrowings used for leverage.

ADMINISTRATIVE SERVICES FEES
Under an Administrative Services Agreement, the Fund pays Ameriprise Financial
an annual fee for administration and accounting services equal to 0.06% of the
Fund's average daily Managed Assets.

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 six months ended June
30, 2010, other expenses paid to this company were $151.

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 RiverSource, Seligman and
Threadneedle 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.

ORGANIZATION EXPENSES AND OFFERING COSTS
The Investment Manager paid all organization expenses of the Fund.

With respect to the Fund's initial public offering, the Investment Manager paid
all offering costs (other than sales load) that exceed $0.04 per share of Common
Stock. The Fund paid offering costs of $21,800 and $572,000 from the proceeds of
the initial public offering costs for the periods ended June 30, 2010 and Dec.
31, 2009, respectively. Offering costs paid by the Fund were charged as a
reduction of paid-in capital at the completion of the Fund offering.

5. SECURITIES TRANSACTIONS

Cost of purchases and proceeds from sales of securities (other than short-term
obligations) aggregated $153,561,108 and $167,856,725, respectively, for the six
months ended June 30, 2010. Realized gains and losses are determined on an
identified cost basis.

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


6. DIVIDEND INVESTMENT PLAN AND STOCK REPURCHASE PROGRAM

The Fund, in connection with its Dividend Investment Plan (the Plan), issues
shares of its own Common Stock, as needed, to satisfy Plan requirements. A total
of 99,579 shares were issued to Plan participants during the six months ended
June 30, 2010 for proceeds of $1,916,216, a weighted average discount of 0.82%
from the market price of those shares.

Pursuant to the Plan, unless a Common Stockholder elects otherwise, all cash
dividends, capital gains distributions, and other distributions are
automatically reinvested in additional Common Stock. If you hold your shares in
street name or other nominee (i.e., through a broker), you should contact them
to determine their policy, as the broker firm's policy with respect to Fund
distributions may be to default to a cash payment. Common Stockholders who elect
not to participate in the Plan (including those whose intermediaries do not
permit participation in the Plan by their customers) will receive all dividends
and distributions payable in cash directly to the Common Stockholder of record
(or, if the shares of Common Stock are held in street or other nominee name,
then to such nominee). Common Stockholders may elect not to participate in the
Plan and to receive all distributions of dividends and capital gains or other
distributions in cash by sending written instructions to American Stock Transfer
& Trust Company, LLC (AST), 59 Maiden Lane Plaza Level, New York, New York
10038. Participation in the Plan may be terminated or resumed at any time
without penalty by written notice if received by AST, prior to the record date
for the next distribution. Otherwise, such termination or resumption will be
effective with respect to any subsequently declared distribution.

Under the Plan, Common Stockholders receive shares of Common Stock in lieu of
cash distributions unless they have elected otherwise as described above. Common
Stock will be issued in lieu of cash by the Fund from previously authorized but
unissued Common Stock. If the market price of a share on the ex-dividend date of
such a distribution is at or above the Fund's net asset value per share on such
date, the number of shares to be issued by the Fund to each Common Stockholder
receiving shares in lieu of cash distributions will be determined by dividing
the amount of the cash distribution to which such Common Stockholder would be
entitled by the greater of the net asset value per share on such date or 95% of
the market price of a share on such date. If the market price of a share on such
an ex-dividend date is below the net asset value per share, the number of shares
to be issued to such Common Stockholders will be determined by dividing such
amount by the per share market price. The issuance of Common Stock at less than
net asset value per share will dilute the net asset value of all Common Stock
outstanding at that time. Market price on any day means the closing price for
the Common Stock at the close of regular

--------------------------------------------------------------------------------
           SELIGMAN PREMIUM TECHNOLOGY GROWTH FUND -- 2010 SEMIANNUAL REPORT  27



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


trading on the NYSE on such day or, if such day is not a day on which the Common
Stock trades, the closing price for the Common Stock at the close of regular
trading on the immediately preceding day on which trading occurs.

The Fund, under its stock repurchase program, currently intends to make open
market purchases of its Common Stock from time to time when the Fund's Common
Stock is trading at a discount to its net asset value, in an amount
approximately sufficient to offset the growth in the number of shares of Common
Stock issued as a result of the reinvestment of the portion of its distributions
to Common Stockholders that are attributable to distributions received by the
Fund from its underlying portfolio investments less fund expenses. No shares
were purchased in the open market during the six months ended June 30, 2010.

The Fund reserves the right to amend or terminate the Plan as applied to any
distribution paid subsequent to written notice of the change sent to
participants in the Plan at least 90 days before the record date for such
distribution. There are no service or brokerage charges to participants in the
Plan; however, the Fund reserves the right to amend the Plan to include a
service charge payable to the Fund by the participants. The Fund reserves the
right to amend the Plan to provide for payment of brokerage fees by Plan
participants in the event the Plan is changed to provide for open market
purchases of Common Stock on behalf of Plan participants. All correspondence
concerning the Plan should be directed to AST.

7. OPTIONS CONTRACTS WRITTEN

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

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

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



Manager. The cost of the Fund's purchases and proceeds from sales of shares of
RiverSource Short-Term Cash Fund aggregated $98,940,061 and $97,236,700,
respectively, for the six months ended June 30, 2010. 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 June 30, 2010, can be found in the
Portfolio of Investments.

9. FEDERAL TAX INFORMATION

Net investment income (loss) and net realized gains (losses) may differ for
financial statement and tax purposes primarily because of options contracts,
foreign currency transactions 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 were recorded by the Fund.

Some of the Fund's investments and positions may be subject to special tax rules
that may change the normal treatment of income, gains and losses recognized by
the Fund (for example, the calls written by the Fund on the NASDAQ 100,
investments in futures transactions or non-U.S. corporations classified as
"passive foreign investment companies"). Those special tax rules can, among
other things, affect the treatment of capital gain or loss as long-term or
short-term and may result in ordinary income or loss rather than capital gain or
loss. The application of these special rules would therefore also affect the
character of distributions made by the Fund, and may increase the amount of
taxes payable by Common Stockholders.

For federal income tax purposes, the Fund had a capital loss carry-over of
$603,951 at Dec. 31, 2009, that if not offset by capital gains will expire in
2017. 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 carryover before it expires.

10. RISKS RELATING TO CERTAIN INVESTMENTS

NON-DIVERSIFICATION RISK
The Fund is non-diversified. A non-diversified fund may invest more of its
assets in fewer companies than if it were a diversified fund. Because each
investment

--------------------------------------------------------------------------------
           SELIGMAN PREMIUM TECHNOLOGY GROWTH FUND -- 2010 SEMIANNUAL REPORT  29



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

has a greater effect on the Fund's performance, the Fund may be more exposed to
the risks of loss and volatility than a fund that invests more broadly.

TECHNOLOGY AND TECHNOLOGY-RELATED INVESTMENT RISK
The Fund will invest a substantial portion of its assets in technology and
technology-related companies. The market prices of technology and technology-
related stocks tend to exhibit a greater degree of market risk and price
volatility than other types of investments. These stocks may fall rapidly in and
out of favor with investors, which may cause sudden selling and dramatically
lower market prices. These stocks also may be affected adversely by changes in
technology, consumer and business purchasing patterns, government regulation
and/or obsolete products or services. In addition, a rising interest rate
environment tends to negatively affect technology and technology-related
companies. In such an environment, those companies with high market valuations
may appear less attractive to investors, which may cause sharp decreases in the
companies' market prices. Further, those technology or technology-related
companies seeking to finance their expansion would have increased borrowing
costs, which may negatively impact their earnings. As a result, these factors
may negatively affect the performance of the Fund. Finally, the Fund may be
susceptible to factors affecting the technology and technology-related
industries, and the Fund's net asset value may fluctuate more than a fund that
invests in a wider range of industries. Technology and technology-related
companies are often smaller and less experienced companies and may be subject to
greater risks than larger companies, such as limited product lines, markets and
financial and managerial resources. These risks may be heightened for technology
companies in foreign markets.

SMALL AND MID-CAP COMPANIES RISK
The Fund may invest all or a substantial portion of its assets in companies
whose market capitalization is considered small- or mid-cap. These companies
often are newer or less established companies than larger companies. Investments
in these companies carry additional risks because earnings of these companies
tend to be less predictable; they often have limited product lines, markets,
distribution channels or financial resources; and the management of such
companies may be dependent upon one or a few key people. The market movements of
equity securities of small-cap and mid-cap companies may be more abrupt or
erratic than the market movements of equity securities of larger, more
established companies or the stock market in general. Historically, small-cap
and mid-cap companies have sometimes gone through extended periods when they did
not perform as well as larger companies. In addition, equity securities of these
companies generally are less liquid than those of larger companies. This means
that the Fund could have greater difficulty selling such securities at the time
and

--------------------------------------------------------------------------------
30  SELIGMAN PREMIUM TECHNOLOGY GROWTH FUND -- 2010 SEMIANNUAL REPORT



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


price that the Fund would like. Smaller-company stocks, as a whole, may
experience larger price fluctuations than large-company stocks or other types of
investments. During periods of investor uncertainty, investor sentiment may
favor large, well-known companies over small, lesser-known companies. There may
be less trading in a smaller company's stock, which means that buy and sell
transactions in that stock could have a larger impact on the stock's price than
is the case with larger company stocks.

WRITING CALL OPTIONS RISK
A principal aspect of the Fund's investment strategy involves writing call
options on the NASDAQ 100. This part of the Fund's strategy subjects the Fund to
certain additional risks. A decision as to whether, when and how to use options
involves the exercise of skill and judgment, and even a well-conceived
transaction may be unsuccessful to some degree because of market behavior or
unexpected events. The principal factors affecting the market value of an option
include supply and demand, interest rates, the current market price of the
underlying index or security in relation to the exercise price of the option,
the actual or perceived volatility of the underlying index or security and the
time remaining until the expiration date.

The Fund intends to write call options on the NASDAQ 100; however, it does not
intend to have a portfolio of securities that mirrors the securities in the
NASDAQ 100. As a result, during a period when the Fund has outstanding call
options written on the NASDAQ 100, the NASDAQ 100 may appreciate to a greater
extent than the securities in the Fund's portfolio. If the call options are
exercised in these circumstances, the Fund's loss on the options will be greater
because it will be paying the option holder not only an amount effectively
representing appreciation on securities in its own portfolio but also an amount
representing the greater appreciation experienced by the securities in the
NASDAQ 100 that the Fund does not own. If, at a time these call options may be
exercised, the securities underlying these options have market values above the
exercise price, then these call options will be exercised and the Fund will be
obligated to deliver to the option holder either the securities underlying these
options or to deliver the cash value of those securities, in exchange for which
the option holder will pay the Fund the exercise price. In either case, the Fund
will incur losses to the extent the market value of the underlying securities
exceed the sum of the premium the Fund received from writing the call options
and the exercise price of the call options, which loss may be very substantial.

To the extent all or part of the Fund's call options are covered, the Fund
forgoes, during the option's life, the opportunity to profit from increases in
the market value of the security underlying the call option above the sum of the
option

--------------------------------------------------------------------------------
           SELIGMAN PREMIUM TECHNOLOGY GROWTH FUND -- 2010 SEMIANNUAL REPORT  31



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


premium received and the exercise price of the call, but has retained the risk
of loss should the price of the underlying security decline below the exercise
price minus the option premium received. The writer of an exchange-listed option
on a security has no control over when during the exercise period of the option
(which may be a single day or multiple days) it may be required to fulfill its
obligation as a writer of the option. Once an option writer has received an
exercise notice, it would be obligated to deliver the underlying security at the
exercise price. Thus, the writing of call options may require the Fund to sell
portfolio securities at inopportune times or for prices other than current
market values and will limit the amount of appreciation the Fund can realize
above the exercise price of an option.

The Fund may be required to sell investments from its portfolio to effect cash
settlement (or transfer ownership of a stock or other instrument to physically
settle) on any written call options that are exercised. Such sales (or
transfers) may occur at inopportune times, and the Fund may incur transaction
costs that increase the expenses borne by Common Stockholders. The Fund may sell
written call options over an exchange or in the OTC market. The options in the
OTC markets may not be as liquid as exchange-listed options. The Fund may be
limited in the number of counterparties willing to take positions opposite the
Fund or may find the terms of such counterparties to be less favorable than the
terms available for listed options. The Fund cannot guarantee that its options
strategies will be effective. Moreover, OTC options may provide less favorable
tax treatment than listed options.

The value of options may be adversely affected if the market for such options
becomes less liquid or smaller. There can be no assurance that a liquid market
will exist when the Fund seeks to close out an option position, in the case of a
call option written, by buying the option back. Reasons for the absence of a
liquid secondary market on an exchange include the following: (i) there may be
insufficient trading interest in certain options; (ii) restrictions may be
imposed by an exchange on opening transactions or closing transactions or both;
(iii) trading halts, suspensions or other restrictions may be imposed with
respect to particular classes or series of options; (iv) unusual or unforeseen
circumstances may interrupt normal operations on an exchange; (v) the facilities
of an exchange or the Options Clearing Corporation (OCC) may not at all times be
adequate to handle current trading volume; or (vi) one or more exchanges could,
for economic or other reasons, decide or be compelled to discontinue the trading
of options (or a particular class or series of options) at some future date. If
trading were discontinued, the secondary market on that exchange (or in that
class or series of options) would cease to exist. However, outstanding options
on that exchange that had been issued by the OCC as a result of trades on that
exchange

--------------------------------------------------------------------------------
32  SELIGMAN PREMIUM TECHNOLOGY GROWTH FUND -- 2010 SEMIANNUAL REPORT



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



would continue to be exercisable in accordance with their terms. The Fund's
ability to terminate OTC options will be more limited than with exchange-traded
options and may involve the risk that broker-dealers participating in such
transactions will not fulfill their obligations.

The hours of trading for options may not conform to the hours during which the
underlying securities are traded. To the extent that the options markets close
before the markets for the underlying securities, significant price and rate
movements can take place in the underlying markets that would not be reflected
concurrently in the options markets. Call options are marked to market daily and
their value will be affected by changes in the value of and dividend rates of
the underlying common stocks, changes in interest rates, changes in the actual
or perceived volatility of the stock market and the underlying common stocks and
the remaining time to the options' expiration. Additionally, the exercise price
of an option may be adjusted downward before the option's expiration as a result
of the occurrence of certain corporate events affecting the underlying equity
security, such as extraordinary dividends, stock splits, merger or other
extraordinary distributions or events. A reduction in the exercise price of an
option would reduce the Fund's capital appreciation potential on the underlying
security.

The Fund's options transactions will be subject to limitations established by
each of the exchanges, boards of trade or other trading facilities on which such
options are traded. These limitations govern the maximum number of options in
each class which may be written or purchased by a single investor or group of
investors acting in concert, regardless of whether the options are written or
purchased on the same or different exchanges, boards of trade or other trading
facilities or are held or written in one or more accounts or through one or more
brokers. Thus, the number of options which the Fund may write or purchase may be
affected by options written or purchased by other investment advisory clients of
the Investment Manager. An exchange, board of trade or other trading facility
may order the liquidation of positions found to be in excess of these limits,
and may impose certain other sanctions.

OPTIONS RISK
The Fund intends to engage in transactions in options on securities, indices,
exchange-traded funds and market baskets of securities on exchanges and in the
OTC markets. In general, exchange-traded options have standardized exercise
prices and expiration dates and require the parties to post margin against their
obligations, and the performance of the parties' obligations in connection with
such options is guaranteed by the exchange or a related clearing corporation.
OTC options have more flexible terms negotiated between the buyer and the

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

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

seller, but generally do not require the parties to post margin and are subject
to greater credit risk. OTC options also involve greater liquidity risk.

In addition to writing call options as described above, the Fund may purchase
put options. By buying a put option, the Fund will pay a premium to acquire a
right to sell the securities or instruments underlying the put at the exercise
price of the option. The Fund will lose money if the securities or instruments
underlying the option do not decline in value below the exercise price of the
option by an amount sufficient to offset the premium paid to acquire the option.
To the extent the Fund purchases put options in the OTC market, the Fund will be
subject to the credit risk of the seller of the option. The Fund also may write
put options on the types of securities or instruments that may be held by the
Fund, provided that such put options are secured by segregated, liquid
instruments. The Fund will receive a premium for writing a put option, which
increases the Fund's return. In exchange for the premium received, the Fund has
the obligation to buy the securities or instruments underlying the option at an
agreed-upon exercise price if the securities or instruments decrease below the
exercise price of the option. The Fund will lose money if the securities or
instruments decrease in value so that the amount the Fund is obligated to pay
the counterparty to the option to purchase the securities underlying the option
upon exercise of the option exceeds the value of those securities by an amount
that is greater than the premium received by the Fund for writing the option.

The Fund may purchase call options on any of the types of securities or
instruments in which it may invest. In exchange for paying the option premium, a
purchased call option gives the Fund the right to buy, and obligates the seller
to sell, the underlying security or instrument at the exercise price. The Fund
will lose money if the securities or instruments underlying the option do not
appreciate in value in an amount sufficient to offset the premium paid by the
Fund to acquire the option.

FOREIGN SECURITIES RISK
The Fund may invest up to 25% of its Managed Assets in securities of companies
organized outside the United States. Investments in foreign securities involve
certain risks not associated with investments in U.S. companies. Securities
markets in certain foreign countries are not as developed, efficient or liquid
as securities markets in the United States. Therefore, the prices of foreign
securities are often volatile and trading costs are higher. Certain foreign
countries may impose restrictions on the ability of issuers of foreign
securities to make payments of principal and interest to investors located
outside the country, due to blockage of foreign currency exchanges or otherwise.
Generally, there is less publicly available information about foreign companies
due to less rigorous

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

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


disclosure or accounting standards and regulatory practices. In addition, the
Fund will be subject to risks associated with adverse political and economic
developments in foreign countries, which could cause the Fund to lose money on
its investments in foreign securities.

The Fund may invest in securities of issuers located or doing substantial
business in "emerging markets" (lesser developed countries). Because of the less
developed markets and economics and, in some countries, less mature governments
and governmental institutions, the risks of investing in foreign securities can
be intensified in the case of investments in issuers domiciled or doing
substantial business in emerging markets. These risks include a high
concentration of market capitalization and trading volume in a small number of
issuers representing a limited number of industries, as well as a high
concentration of investors and financial intermediaries; political and social
uncertainties; over-dependence on exports, especially with respect to primary
commodities, making these economies vulnerable to changes in commodity prices;
overburdened infrastructure and obsolete or unseasoned financial systems;
environmental problems; less developed legal systems; and less reliable
custodial services and settlement practices.

11. 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 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 statement.

12. 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
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

--------------------------------------------------------------------------------
           SELIGMAN PREMIUM TECHNOLOGY GROWTH FUND -- 2010 SEMIANNUAL REPORT  35



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


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 (the
Supreme Court), asking the Supreme Court to stay the District Court proceedings
while the 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. On March 30, 2010, the Supreme Court issued its ruling in Jones v.
Harris Associates, and on April 5, 2010, the Supreme Court vacated the Eighth
Circuit's decision in the Gallus case and remanded the case to the Eighth
Circuit for further consideration in light of the Supreme Court's decision in
Jones v. Harris Associates. On June 4, 2010, the Eighth Circuit remanded the
Gallus case to the District Court for further consideration in light of the
Supreme Court's decision in Jones v. Harris Associates.

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, Seligman and Threadneedle
funds' Boards of Directors/Trustees.

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

--------------------------------------------------------------------------------
36  SELIGMAN PREMIUM TECHNOLOGY GROWTH FUND -- 2010 SEMIANNUAL REPORT



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



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.
