Under the Fund’s managed distribution policy and subject to the approval of the Fund’s Board of Directors (the Board), the Fund expects to make quarterly cash distributions (in February, May, August and November) to Common Stockholders. The Fund’s most recent distribution (August 25, 2015) amounted to $0.4625 per share, which is equal to a quarterly rate of 2.3125% (9.25% annualized) of the $20.00 offering price in the Fund’s initial public offering in November 2009. This distribution is equal to a quarterly rate of 2.559% (10.2380% annualized) of the Fund’s market price of $18.07 per share as of July 31, 2015. You should not draw any conclusions about the Fund’s investment performance from the amount of the distribution or from the terms of the Fund’s distribution policy. Historically, the Fund has distributed more than its income and net realized capital gains, which has resulted in Fund distributions substantially consisting of return of capital or other capital source. A return of capital may occur, for example, when some or all of the money that you invested in the Fund is paid back to you. A return of capital distribution does not necessarily reflect the Fund’s investment performance and should not be confused with ‘yield’ or ‘income’. As of the payment date of the most recent distribution, all Fund distributions paid in 2015 (as estimated by the Fund based on current information) are from the earnings and profits of the Fund and not a return of capital. This could change during the remainder of the year. The Fund’s Board may determine in the future that the Fund’s managed distribution policy and the amount or timing of the distributions should not be continued in light of changes in the Fund’s portfolio holdings, market or other conditions or factors, including that the distribution rate under such policy may not be dependent upon the amount of the Fund’s earned income or realized capital gains. The Board could also consider amending or terminating the current distribution policy because of potential adverse tax consequences associated with maintaining the policy. In certain situations, returns of capital could be taxable for federal income tax purposes, and all or a portion of the Fund’s capital loss carryforwards from prior years, if any, could effectively be forfeited. The Board may amend or terminate the Fund’s distribution policy at any time without prior notice to Fund stockholders; any such change or termination may have an adverse effect on the market price of the Fund’s shares.

See Notes to Financial Statements for additional information related to the Fund’s managed distribution policy.

Dear Stockholders,

We are pleased to present the semiannual stockholder report for Columbia Seligman Premium Technology Growth Fund (the Fund). The report includes the Fund’s investment results, a portfolio of investments and financial statements as of June 30, 2015.

The Fund’s Common Stock gained 9.57%, based on net asset value, and 3.72%, based on market price, for the six months ended June 30, 2015. The Fund outperformed its benchmark, the S&P North American Technology Sector Index, which returned 2.30% during the same time period.

During the first half of 2015, the Fund paid two distributions, in accordance with its managed distribution policy, that aggregated to $0.925 per share of Common Stock of the Fund.

During the meeting, Stockholders elected one Director, re-elected three Directors and ratified the selection of PricewaterhouseCoopers LLP (PricewaterhouseCoopers) as the Fund’s independent registered public accounting firm for 2015.

PERFORMANCE OVERVIEW

(Unaudited)

Performance Summary

Columbia Seligman Premium Technology Growth Fund (the Fund) Common Stock returned 3.72%, based on market price, and 9.57%, based on net asset value, for the six-month period ended June 30, 2015.

The Fund outperformed its benchmark, the S&P North American Technology Sector Index, which returned 2.30% over the same time period.


Average Annual Total Returns (%) (for period ended June 30, 2015)
	Inception	6 Months Cumulative		1 Year		5 Years		Life
Market Price	11/24/09		3.72		22.47		12.30		9.88
Net Asset Value	11/30/09		9.57		16.88		13.34		10.56
S&P North American Technology Sector Index			2.30		10.21		17.91		14.84

Life total return for market price is based on the initial offering price on November 24, 2009, which was $20.00 per share.

Life total return for net asset value (NAV) is from the opening of business on November 30, 2009 and includes the 4.50% initial sales load. The NAV price per share of the Fund’s Common Stock at inception was $19.10.

Index inception return is calculated from 11/30/2009.

Performance data quoted represents past performance and current performance may be lower or higher. Past performance is no guarantee of future results. The investment return and principal value will fluctuate so that shares, when sold, may be worth more or less than the original cost. For current month-end performance information, please visit columbiathreadneedle.com/us.

Returns reflect changes in market price or net asset value, as applicable, and assume reinvestment of distributions. Returns do not reflect the deduction of taxes that investors may pay on distributions or the sale of shares.

The S&P North American Technology Sector Index is an unmanaged modified capitalization-weighted index based on a universe of technology-related stocks.

Indices are not available for investment, are not professionally managed and do not reflect sales charges, fees, brokerage commissions, taxes or other expenses of investing. Securities in the Fund may not match those in an index.

The net asset value of the Fund’s shares may not always correspond to the market price of such shares. Common stock of many closed-end funds frequently trade at a discount from their net asset value. The Fund is subject to stock market risk, which is the risk that stock prices overall will decline over short or long periods, adversely affecting the value of an investment in the Fund.

COLUMBIA SELIGMAN PREMIUM TECHNOLOGY GROWTH FUND

FUND OBJECTIVES AND RULES-BASED OPTION STRATEGY

(Unaudited)

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 and (ii) writing call options on the NASDAQ 100 Index^®, 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 0% to 90% of the underlying value of the Fund’s holdings of Common Stock (the Rules-based Option Strategy). 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.

The Fund’s Rules-based Option Strategy with respect to writing call options is as follows:


When the VXN Index^(a) is:		Aggregate Notional Amount of Written Call Options as a Percentage of the Fund’s Holdings in Common Stocks
17 or less		25%
Greater than 17, but less than 18		Increase up to 50%
At least 18, but less than 33		50%
At least 33, but less than 34		Increase up to 90%
At least 34, but less than 55		90%
At 55 or greater		0% to 90%

(a)	The VXN Index is a leading barometer of investor sentiment and market volatility relating to the NASDAQ 100 Index.

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.

Fair Value Measurements

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’s 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 (including NAV for open-end mutual funds). 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 Investment Manager, 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.

The accompanying Notes to Financial Statements are an integral part of this statement.

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 may rely on one or more significant unobservable inputs and/or significant assumptions by the Investment Manager. Inputs used in valuations may include, but are not limited to, financial statement analysis, capital account balances, discount rates and estimated cash flows, and comparable company data.

Under the direction of the Fund’s Board of Directors (the Board), the Investment Manager’s Valuation Committee (the Committee) is responsible for overseeing the valuation procedures approved by the Board. The Committee consists of voting and non-voting members from various groups within the Investment Manager’s organization, including operations and accounting, trading and investments, compliance, risk management and legal.

The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation control policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review time-sensitive information or approve related valuation actions. The Committee reports to the Board, with members of the Committee meeting with the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

For investments categorized as Level 3, the Committee monitors information similar to that described above, which may include: (i) data specific to the issuer or comparable issuers, (ii) general market or specific sector news and (iii) quoted prices and specific or similar security transactions. The Committee considers this data and any changes from prior periods in order to assess the reasonableness of observable and unobservable inputs, any assumptions or internal models used to value those securities and changes in fair value. This data is also used to corroborate, when available, information received from approved pricing vendors and brokers. Various factors impact the frequency of monitoring this information (which may occur as often as daily). However, the Committee may determine that changes to inputs, assumptions and models are not required as a result of the monitoring procedures performed.

The following table is a summary of the inputs used to value the Fund’s investments at June 30, 2015:

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 Stock 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 Stock 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 on distributions or on the sale of Fund shares. Total returns and portfolio turnover are not annualized for periods of less than one year. The portfolio turnover rate is calculated without regard to purchase and sales transactions of short-term instruments and certain derivatives, if any. If such transactions were included, the Fund’s portfolio turnover rate may be higher.

Semiannual Report 2015			13



		COLUMBIA SELIGMAN PREMIUM TECHNOLOGY GROWTH FUND

NOTES TO FINANCIAL STATEMENTS

June 30, 2015 (Unaudited)

Note 1. Organization

Columbia Seligman Premium Technology Growth Fund (the Fund) is a non-diversified fund. The Fund is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as a closed-end management investment company.

The Fund was incorporated under the laws of the State of Maryland on September 3, 2009, and commenced investment operations on November 30, 2009. The Fund had no investment operations prior to November 30, 2009 other than those relating to organizational matters and the sale to Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), of 5,250 common shares (Common Stock) at a cost of $100,275 on October 14, 2009. As of December 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 January 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. The issued and outstanding Common Stock trades on the New York Stock Exchange (NYSE) under the symbol “STK”.

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.

Note 2. Summary of Significant Accounting Policies

Basis of Preparation

The Fund is an investment company that applies the accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946, Financial Services —Investment Companies (ASC 946). The financial statements are prepared in accordance with U.S. generally accepted accounting principles (GAAP), which requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.

The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements.

Security Valuation

All equity securities are valued at the close of business of the NYSE. Equity securities are valued at the last quoted sales price on the principal exchange or market on which they trade, except for securities traded on the NASDAQ Stock Market, which are valued at the NASDAQ official close price. Unlisted securities or listed securities for which there were no sales during the day are valued at the mean of the latest quoted bid and ask prices on such exchanges or markets.

Foreign equity securities are valued based on the closing price on the foreign exchange in which such securities are primarily traded. If any foreign equity security closing prices are not readily available, the securities are valued at the mean of the latest quoted bid and ask prices on such exchanges or markets. Foreign currency exchange rates are generally determined at 4:00 p.m. Eastern (U.S.) time. Many securities markets and exchanges outside the U.S. close prior to the close of the NYSE; therefore, the closing prices for securities in such


14		Semiannual Report 2015



COLUMBIA SELIGMAN PREMIUM TECHNOLOGY GROWTH FUND

NOTES TO FINANCIAL STATEMENTS (continued)

June 30, 2015 (Unaudited)

markets or on such exchanges may not fully reflect events that occur after such close but before the close of the NYSE. In those situations, foreign securities will be fair valued pursuant to a policy adopted by the Board of Directors (the Board), including, if available, utilizing a third party pricing service to determine these fair values. The third party pricing service takes into account multiple factors, including, but not limited to, movements in the U.S. securities markets, certain depositary receipts, futures contracts and foreign exchange rates that have occurred subsequent to the close of the foreign exchange or market, 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.

Investments in open-end investment companies, including money market funds, are valued at their latest net asset value.

Option contracts are valued at the mean of the latest quoted bid and asked prices on their primary exchanges. Option contracts, including over-the-counter option contracts, with no readily available market quotations are valued using quotes obtained from independent brokers as of the close of the NYSE.

Investments for which market quotations are not readily available, or that have quotations which management believes are not reflective of market value or reliable, are valued at fair value as determined in good faith under procedures approved by and under the general supervision of the Board. If a security or class of securities (such as foreign securities) is valued at fair value, such value is likely to be different from the quoted or published price for the security.

The determination of fair value often requires significant judgment. To determine fair value, management may use assumptions including but not limited to future cash flows and estimated risk premiums. Multiple inputs from various sources may be used to determine fair value.

GAAP requires 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. This information is disclosed following the Fund’s Portfolio of Investments.

Derivative Instruments

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 Index^®, an unmanaged index that includes the largest and most active nonfinancial domestic and international companies listed on the Nasdaq Stock Market, or its exchange-traded fund equivalent (NASDAQ 100) on a month-to-month basis.

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, exchange-traded funds (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.

The notional amounts of derivative instruments, if applicable, are not recorded in the financial statements. A derivative instrument may suffer a mark to market loss if the value of the contract decreases due to an unfavorable change in the market rates or values of the underlying instrument. Losses can also occur if the counterparty does not perform under the contract. Options written by the Fund do not typically give rise to counterparty credit risk, as options written generally obligate the Fund and not the counterparty to perform. With exchange-traded purchased options, there is minimal counterparty credit risk to the Fund since the exchange’s clearinghouse, as counterparty to such instruments, guarantees against a possible default. The clearinghouse stands between the buyer and the seller of the contract; therefore, the counterparty credit risk is limited to failure of the clearinghouse. However, credit risk still exists in exchange traded option contracts with respect to any collateral that is held in a broker’s customer accounts. While brokers are required to segregate customer collateral from their own assets, in


Semiannual Report 2015			15



		COLUMBIA SELIGMAN PREMIUM TECHNOLOGY GROWTH FUND

NOTES TO FINANCIAL STATEMENTS (continued)

June 30, 2015 (Unaudited)

the event that a broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of collateral held by the broker for all its clients, U.S. bankruptcy laws will typically allocate that shortfall on a pro-rata basis across all the broker’s customers, potentially resulting in losses to the Fund.

In order to better define its contractual rights and to secure rights that will help the Fund mitigate its counterparty risk, the Fund may enter into an International Swaps and Derivatives Association, Inc. Master Agreement (ISDA Master Agreement) or similar agreement with its derivative contract counterparties. An ISDA Master Agreement is a bilateral agreement between a Fund and a counterparty that governs OTC derivatives and foreign exchange contracts and typically contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative financial instrument’s payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default (close-out netting) including the bankruptcy or insolvency of the counterparty. Note, however, that bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset in bankruptcy, insolvency or other events. Collateral (margin) requirements differ by type of derivative. Margin requirements are established by the exchange for exchange traded options. Brokers can ask for margin in excess of the minimum in certain circumstances. To the extent amounts due to the Fund from its counterparties are not fully collateralized, contractually or otherwise, the Fund bears the risk of loss from counterparty nonperformance. The Fund attempts to mitigate counterparty risk by only entering into agreements with counterparties that it believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties.

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

Options Contracts

Options are contracts which entitle the holder to purchase or sell securities or other identified assets at a specified price, or in the case of index option contracts, to receive or pay the difference between the index value

and the strike price of the index option contract. Option contracts can be either exchange-traded or over-the-counter. The Fund purchased and wrote option contracts to decrease the Fund’s exposure to equity risk and to increase return on investments. These instruments may be used for other purposes in future periods. Completion of transactions for option contracts traded in the over-the-counter market depends upon the performance of the other party. Cash collateral may be collected or posted by the Fund to secure certain over-the-counter option contract trades. Cash collateral held or posted by the Fund for such option contract trades must be returned to the counterparty or the Fund upon closure, exercise or expiration of the contract.

Options contracts purchased are recorded as investments. When the Fund writes an options contract, the premium received is recorded as an asset and an amount equivalent to the premium is recorded as a liability in the Statement of Assets and Liabilities and is subsequently adjusted to reflect the current fair value of the option written. Changes in the fair value of the written option are recorded as unrealized appreciation or depreciation until the contract is exercised or has expired. The Fund will realize a gain or loss when the option contract is closed or expires. When option contracts are exercised, the proceeds on sales for a written call or purchased put option contract, or the purchase cost for a written put or purchased call option contract, is adjusted by the amount of premium received or paid.

For over-the-counter options purchased, the Fund bears the risk of loss of the amount of the premiums paid plus the positive change in market values net of any collateral held by the Fund should the counterparty fail to perform under the contracts. Option contracts written by the Fund do not typically give rise to counterparty credit risk, as options written generally obligate the Fund and not the counterparty to perform. The risk in writing a call option contract is that the Fund gives up the opportunity for profit if the market price of the security increases above the strike price and the option contract is exercised. The risk in writing a put option contract is that the Fund may incur a loss if the market price of the security decreases below the strike price and the option contract is exercised. Exercise of a written option could result in the Fund purchasing or selling a security or foreign currency when it otherwise would not, or at a price different from the current market value. In purchasing and writing options, the Fund bears the risk of an unfavorable change in the value of the underlying instrument or the

NOTES TO FINANCIAL STATEMENTS (continued)

June 30, 2015 (Unaudited)

NOTES TO FINANCIAL STATEMENTS (continued)

June 30, 2015 (Unaudited)

The Fund may receive distributions from holdings in equity securities, business development companies (BDCs), exchange-traded funds (ETFs), other regulated investment companies (RICs), and real estate investment trusts (REITs), which report information on the tax character of their distributions annually. These distributions are allocated to dividend income, capital gain and return of capital based on actual information reported. Return of capital is recorded as a reduction of the cost basis of securities held. If the Fund no longer owns the applicable securities, return of capital is recorded as a realized gain. With respect to REITs, to the extent actual information has not yet been reported, estimates for return of capital are made by the Fund’s management. Management’s estimates are subsequently adjusted when the actual character of the distributions is disclosed by the REITs, which could result in a proportionate change in return of capital to shareholders.

Awards from class action litigation are recorded as a reduction of cost basis if the Fund still owns the applicable securities on the payment date. If the Fund no longer owns the applicable securities, the proceeds are recorded as realized gains.

Federal Income Tax Status

The Fund intends to qualify each year as a regulated investment company under Subchapter M of the Internal Revenue Code, as amended, and will distribute substantially all of its taxable income (including net short-term capital gains), if any, for its tax year, and as such will not be subject to federal income taxes. In addition, the Fund intends to distribute in each calendar year substantially all of its net investment income, capital gains and certain other amounts, if any, such that the Fund should not be subject to federal excise tax. Therefore, no federal income or excise tax provision is recorded.

Foreign Taxes

The Fund may be subject to foreign taxes on income, gains on investments or currency repatriation, a portion of which may be recoverable. The Fund will accrue such taxes and recoveries, as applicable, based upon its current interpretation of tax rules and regulations that exist in the markets in which it invests.

Realized gains in certain countries may be subject to foreign taxes at the Fund level, based on statutory rates. The Fund accrues for such foreign taxes on realized and unrealized gains at the appropriate rate for each

jurisdiction, as applicable. The amount, if any, is disclosed as a liability on the Statement of Assets and Liabilities.

Dividends to Stockholders

In November 2010, the Fund paid its first dividend under the Fund’s new, managed distribution policy adopted by the Fund’s Board. Prior to the managed distribution policy, the Fund paid distributions pursuant to a level rate distribution policy. Under its former distribution policy and consistent with the 1940 Act, as amended, the Fund could not distribute long-term capital gains, as defined in the Internal Revenue Code of 1986, more often than once in any one taxable year. In October 2010, the Fund received exemptive relief from the Securities and Exchange Commission that permits the Fund to distribute long-term capital gains more often than once in any one taxable year. After consideration by the Fund’s Board, the Fund adopted the current managed distribution policy which allows the Fund to make periodic distributions of long-term capital gains. Under its managed 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. 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 (other than net short-term and long-term capital gains) less all expenses of the Fund.

The Board may change the Fund’s distribution policy and the amount or timing of the distributions, based on a number of factors, including, but not limited to, as the

Fund’s portfolio and market conditions change, the amount of the Fund’s undistributed net investment income and net short- and long-term capital gains and historical and projected net investment income and net short- and long-term capital gains. 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.

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

Guarantees and Indemnifications

Under the Fund’s organizational documents and, in some cases, by contract, 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.

Recent Accounting Pronouncement

Fair Value Measurement (Topic 820), Disclosure for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent)

In May 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2015-07, Fair Value Measurement (Topic 820), Disclosure for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent). ASU No. 2015-07 changes the disclosure requirements for investments for which fair value is measured using the net asset value per share practical expedient. The disclosure requirements are effective for annual periods beginning after December 15, 2016 and interim periods within those fiscal years. At this time, management is evaluating the implications of this guidance and the impact it will have on the financial statement amounts and footnote disclosures, if any.

Note 3. Fees and Compensation Paid to Affiliates

Investment Management Fees

Under an Investment Management Services Agreement, the Investment Manager determines which securities will be purchased, held or sold. The investment management fee is an annual fee that is equal to 1.00% of the Fund’s average daily Managed Assets. “Managed Assets” means 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.

Administration Fees

Under an Administrative Services Agreement, the Investment Manager also serves as the Fund Administrator. The Fund pays the Fund Administrator an annual fee for administration and accounting services equal to 0.06% of the Fund’s average daily Managed Assets.

Other Expenses

Other expenses are for, among other things, miscellaneous expenses of the Fund or the Board, including payments to Board Services Corp., a company providing limited administrative services to the Fund and the Board. That company’s expenses include boardroom and office expense, employee compensation, employee health and retirement benefits, and certain other expenses. For the six months ended June 30, 2015, other expenses paid by the Fund to this company were $814.

Compensation of Board Members

Board members are compensated for their services to the Fund as disclosed in the Statement of Operations. Under a Deferred Compensation Plan (the Plan), the Board members who are not “interested persons” of the Fund, as defined under the 1940 Act, may elect to defer payment of up to 100% of their compensation. Deferred amounts are treated as though equivalent dollar amounts had been invested in shares of certain funds managed by the Investment Manager. The Fund’s liability for these amounts is adjusted for market value changes and remains in the Fund until distributed in accordance with the Plan.

Note 4. Federal Tax Information

The timing and character of income and capital gain distributions are determined in accordance with income

NOTES TO FINANCIAL STATEMENTS (continued)

June 30, 2015 (Unaudited)

tax regulations, which may differ from GAAP because of temporary or permanent book to tax differences.

At June 30, 2015, the cost of investments for federal income tax purposes was approximately $220,299,000 and the aggregate gross approximate unrealized appreciation and depreciation based on that cost was:


Unrealized appreciation	$69,748,000
Unrealized depreciation	(6,728,000	)
Net unrealized appreciation	$63,020,000

Management of the Fund has concluded that there are no significant uncertain tax positions in the Fund that would require recognition in the financial statements. However, management’s conclusion may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws, regulations, and administrative interpretations (including relevant court decisions). Generally, the Fund’s federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service.

Note 5. Portfolio Information

The cost of purchases and proceeds from sales of securities, excluding short-term investments and derivatives, if any, aggregated to $78,211,131 and $88,066,115, respectively, for the six months ended June 30, 2015. The amount of purchase and sale activity impacts the portfolio turnover rate reported in the Financial Highlights.

Note 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 7,531 shares were issued to Plan participants during the six months ended June 30, 2015 for proceeds of $136,473, a weighted average discount of 0.25% from the net asset value 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 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


20		Semiannual Report 2015

NOTES TO FINANCIAL STATEMENTS (continued)

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, 2015.

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.

Note 7. Affiliated Money Market Fund

The Fund invests in Columbia Short-Term Cash Fund, an affiliated money market fund established for the exclusive use by the Fund and other affiliated funds. The income earned by the Fund from such investments is included as Dividends — affiliated issuers in the Statement of Operations. As an investing fund, the Fund indirectly bears its proportionate share of the expenses of Columbia Short-Term Cash Fund.

Note 8. Significant Risks

Non-Diversification Risk

A non-diversified fund is permitted to invest a greater percentage of its total assets in fewer issuers than a diversified fund. The Fund may, therefore, have a greater risk of loss from a few issuers than a similar fund that invests more broadly.

Technology and Technology-related Investment Risk

The Fund invests 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 in and out of favor with investors rapidly, 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.

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


Semiannual Report 2015			21



		COLUMBIA SELIGMAN PREMIUM TECHNOLOGY GROWTH FUND

NOTES TO FINANCIAL STATEMENTS (continued)

June 30, 2015 (Unaudited)

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 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 costs 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 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


22		Semiannual Report 2015



COLUMBIA SELIGMAN PREMIUM TECHNOLOGY GROWTH FUND

NOTES TO FINANCIAL STATEMENTS (continued)

June 30, 2015 (Unaudited)

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 engages 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 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.

Small and Mid-cap Companies Risk

The Fund may invest all or a substantial portion of its Managed 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 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.


Semiannual Report 2015			23



		COLUMBIA SELIGMAN PREMIUM TECHNOLOGY GROWTH FUND

NOTES TO FINANCIAL STATEMENTS (continued)

June 30, 2015 (Unaudited)

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.

Active Management Risk

Due to its active management, the Fund could underperform its benchmark index and/or other funds with similar investment objectives.

Issuer Risk

An issuer in which the Fund invests may perform poorly, and the value of its securities may therefore decline,

which would negatively affect the Fund’s performance. Poor performance may be caused by poor management decisions, competitive pressures, breakthroughs in technology, reliance on suppliers, labor problems or shortages, corporate restructurings, fraudulent disclosures, natural disasters or other events, conditions or factors.

Market Risk

Market risk refers to the possibility that the market values of securities or other investments that the Fund holds will fall, sometimes rapidly or unpredictably, or fail to rise. An investment in the Fund could lose money over short or even long periods.

Note 9. Subsequent Events

Management has evaluated the events and transactions that have occurred through the date the financial statements were issued and noted no items requiring adjustment of the financial statements or additional disclosure.

Note 10. Information Regarding Pending and Settled Legal Proceedings

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 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 Funds’ Boards of Directors.

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


24		Semiannual Report 2015



COLUMBIA SELIGMAN PREMIUM TECHNOLOGY GROWTH FUND

NOTES TO FINANCIAL STATEMENTS (continued)

June 30, 2015 (Unaudited)

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 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 quarterly (10-Q), annual (10-K) and, as necessary, 8-K filings with the SEC 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.

		COLUMBIA SELIGMAN PREMIUM TECHNOLOGY GROWTH FUND

INTERIM APPROVAL OF INVESTMENT MANAGEMENT SERVICES AGREEMENT

Columbia Management Investment Advisers, LLC (Columbia Management or the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), serves as the investment manager to Columbia Seligman Premium Technology Growth Fund (the Fund). Under an investment management services agreement (the IMS Agreement), Columbia Management provides investment advice and other services to the Fund and other funds distributed by Columbia Management Investment Distributors, Inc. (collectively, the Funds).

The Fund’s Board of Directors (the Board), including the independent Board members (the Independent Directors), considered the renewal of the IMS Agreement for a two-month period (“Short-Term Period”) in order to align the IMS Agreement with the review cycle of other funds in the Columbia family of funds. Columbia Management prepared detailed reports for the Board and its Contracts Committee in January, March and April 2015, including reports based on analyses of data provided by an independent organization (Lipper) and a comprehensive response to each item of information requested by independent legal counsel to the Independent Directors (Independent Legal Counsel) in a letter to the Investment Manager, to assist the Board in making this determination. In addition, throughout the year, the Board (or its committees) regularly meets with portfolio management teams and senior management personnel, and reviews information prepared by Columbia Management addressing the services Columbia Management provides and Fund performance. The Board also accords appropriate weight to the work, deliberations and conclusions of the Contracts Committee, the Investment Review Committee and the Compliance Committee in determining whether to continue the IMS Agreement.

The Board, at its April 13-15, 2015 in-person Board meeting (the April Meeting), considered the renewal of the IMS Agreement for the Short-Term Period. At the April Meeting, Independent Legal Counsel reviewed with the Independent Directors various factors relevant to the Board’s consideration of advisory agreements and the Board’s legal responsibilities related to such consideration. Following an analysis and discussion of the factors identified below, the Board, including all of the Independent Directors, approved the renewal of the IMS Agreement for the Short-Term Period.

Nature, Extent and Quality of Services Provided by Columbia Management

The Independent Directors analyzed various reports and presentations they had received detailing the services performed by Columbia Management, as well as its expertise, resources and capabilities. The Independent Directors specifically considered many developments during the past year concerning the services provided by Columbia Management. The Independent Directors noted the information they received concerning Columbia Management’s ability to retain its key portfolio management personnel. In evaluating the quality of services provided under the IMS Agreement and the Fund’s Administrative Services Agreement, the Independent Directors also took into account the organization and strength of the Fund’s and its service providers’ compliance programs. In addition, the Board also reviewed the financial condition of Columbia Management (and its affiliates) and each entity’s ability to carry out its responsibilities under the IMS Agreement and the Fund’s other services agreements with affiliates of Ameriprise Financial, observing the financial strength of Ameriprise Financial, with its solid balance sheet. The Board also discussed the acceptability of the terms of the IMS Agreement for the Short-Term Period.

Based on the foregoing, and based on other information received (both oral and written, including the information on investment performance referenced below) and other considerations, the Board concluded that the services being performed by Columbia Management and its affiliates were acceptable for the Short-Term Period.

Investment Performance

For purposes of evaluating the nature, extent and quality of services provided under the IMS Agreement, the Board carefully reviewed the investment performance of the Fund. In this regard, the Board considered detailed reports providing the results of analyses performed by an independent organization showing, for various periods, the performance of the Fund, the performance of a benchmark index, the percentage ranking of the Fund among its comparison group and the net assets of the Fund. The Board observed that for purposes of approving the IMS Agreement for the Short-Term Period, the Fund’s performance was acceptable.

Comparative Fees, Costs of Services Provided and the Profits Realized by Columbia Management and its Affiliates from their Relationships with the Fund

The Board reviewed comparative fees and the costs of services provided under the IMS Agreement. The Board members considered detailed comparative information set forth in an annual report on fees and expenses, including, among other things, data (based on analyses conducted by an independent organization) showing a comparison of the Fund’s expenses with median expenses paid by funds in its comparative peer universe, as well as data showing the Fund’s contribution to Columbia Management’s profitability.

The Board accorded particular weight to the notion that the level of fees should reflect a rational pricing model applied consistently across the various product lines in the Fund family, while assuring that the overall fees for each Fund (with certain defined exceptions) are generally in line with the “pricing philosophy” currently in effect (i.e., that the total expense ratio of the Fund is no higher than the median expense ratio of funds in the same comparison universe of the Fund).

Economies of Scale to be Realized

The Board noted that the management fee schedule does not contain breakpoints that reduce the fee rate on assets above specified levels. However, due to the Fund’s closed-end structure, the Board did not view the potential for realization of economies of scale as the Fund’s assets grow to be a material factor in its deliberations.

Based on the foregoing, the Board, including all of the Independent Directors, concluded that, for purposes of its consideration of the renewal of the IMS Agreement for the Short-Term Period, the investment management service fees were fair and reasonable in light of the extent and quality of services provided. In reaching this conclusion, no single factor was determinative. The Board noted its understanding that it would undertake the full consideration of renewal of the IMS Agreement for the full annual period at its June 2015 meetings. On April 15, 2015, the Board, including all of the Independent Directors, approved the renewal of the IMS Agreement for the Short-Term Period.

APPROVAL OF INVESTMENT MANAGEMENT SERVICES AGREEMENT

Columbia Management Investment Advisers, LLC (Columbia Management or the Investment Manager, and together with its global affiliates, Columbia Threadneedle), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), serves as the investment manager to Columbia Seligman Premium Technology Growth Fund, Inc. (the Fund). Under an investment management services agreement (the IMS Agreement), Columbia Management provides investment advice and other services to the Fund and other funds distributed by Columbia Management Investment Distributors, Inc. (collectively, the Funds).

On an annual basis, the Fund’s Board of Directors (the Board), including the independent Board members (the Independent Directors), considers renewal of the IMS Agreement. Columbia Management prepared detailed reports for the Board and its Contracts Committee in January, March, April and June 2015, including reports based on analyses of data provided by an independent organization (Lipper) and a comprehensive response to items of information requested by independent legal counsel to the Independent Directors (Independent Legal Counsel) in a letter to the Investment Manager, to assist the Board in making this determination. All of the materials presented in January, March, April and June were first supplied in draft form to designated representatives of the Independent Directors, i.e., Independent Legal Counsel, Fund Counsel, the Chair of the Board and the Chair of the Contracts Committee, and the final materials were revised to reflect discussion and subsequent requests made by the Board representatives. In addition, throughout the year, the Board (or its committees) regularly meets with portfolio management teams and senior management personnel and reviews information prepared by Columbia Management addressing the services Columbia Management provides and Fund performance. The Board also accords appropriate weight to the work, deliberations and conclusions of the Contracts Committee, the Investment Review Committee and the Compliance Committee in determining whether to continue the IMS Agreement.

The Board, at its June 15-17, 2015 in-person Board meeting (the June Meeting), considered the renewal of the IMS Agreement for an additional one-year term. At the June Meeting, Independent Legal Counsel reviewed with the Independent Directors various factors relevant to the Board’s consideration of advisory agreements and the Board’s legal responsibilities related to such consideration. Following an analysis and discussion of the factors identified below, the Board, including all of the Independent Directors, approved the renewal of the IMS Agreement.

Nature, Extent and Quality of Services Provided by Columbia Management

The Independent Directors analyzed various reports and presentations they had received detailing the services performed by Columbia Management, as well as its organization, expertise, resources and capabilities.

The Independent Directors specifically considered many developments during the past year concerning the services provided by Columbia Management, including, in particular, the restructured leadership in the Chief Investment Officer’s organization, the strengthening of the investment research department, the solidifying of the Global Asset Management initiative and the restructured investment risk management organization. The Board also noted the broad scope of services provided by Columbia Management to each Fund, including, among other services, investment, risk and compliance oversight. The Board also took into account the information it received concerning Columbia Management’s ability to attract and retain key portfolio management personnel.

In connection with the Board’s evaluation of the overall package of services provided by Columbia Management, the Board also considered the quality of administrative services provided to the Fund by Columbia Management, recalling the information it received highlighting achievements in 2014 in the performance of administrative services. In evaluating the quality of services provided under the IMS Agreement and the Fund’s Administrative Services Agreement, the Independent Directors also took into account the organization and strength of the Fund’s and its service providers’ compliance programs. In addition, the Board reviewed the financial condition of Columbia Management and its affiliates and each entity’s ability to carry out its responsibilities under the IMS Agreement and the Fund’s other service agreements with affiliates of Ameriprise Financial, observing the financial strength of Ameriprise Financial, with its solid balance sheet. The Board also discussed the acceptability of the terms of the IMS Agreement (including the relatively broad scope of services required to be performed by Columbia Management). The Board took into account the proposed combination of the forms of IMS Agreements and Administrative Services Agreements into a single form of agreement with the combined form reflecting no proposed change in services or fees. Given no material change, the Directors agreed to the combined form, to be effective upon each Fund’s next annual update. The Board concluded that the services being performed under the IMS Agreement and the Administrative Services Agreement were of a reasonably high quality.

APPROVAL OF INVESTMENT MANAGEMENT SERVICES AGREEMENT (continued)

Investment Performance

For purposes of evaluating the nature, extent and quality of services provided under the IMS Agreement, the Board carefully reviewed the investment performance of the Fund. In this regard, the Board considered detailed reports providing the results of analyses performed by an independent organization showing, for various periods, the performance of the Fund, the performance of a benchmark index, the percentage ranking of the Fund among its comparison group and the net assets of the Fund. The Board observed that the Fund’s investment performance met expectations.

Comparative Fees, Costs of Services Provided and the Profits Realized by Columbia Management and its Affiliates from their Relationships with the Fund

The Board considered the reports of its independent fee consultant, JDL, which assisted in its analysis of the Funds’ performance and expenses, and JDL’s conclusion that the effective investment management fee rate for the Fund remains within a reasonable range. The Board accorded particular weight to the notion that the level of fees should reflect a rational pricing model applied consistently across the various product lines in the Fund family, while assuring that the overall fees for each Fund (with certain defined exceptions) are generally in line with the “pricing philosophy” currently in effect (i.e., that the total expense ratio of the Fund is no higher than the median expense ratio of funds in the same comparison universe of the Fund). With respect to the Fund, a closed-end fund, the Board observed that although the Fund’s expense ratio was higher than the comparative peer group’s median expense ratio, the Fund, unlike many funds in the peer universe, employs a unique options-writing strategy designed to cushion its downside performance. The Board also observed that the peer universe did not include funds with similar technology-focused investment strategies. Based on its review, the Board concluded that the Fund’s management fee was fair and reasonable in light of the extent and quality of services that the Fund receives.

The Board also considered the expected profitability of Columbia Management and its affiliates in connection with Columbia Management providing investment management services to the Fund. In this regard, the Independent Directors referred to their detailed analysis of the Profitability Report, discussing the profitability to Columbia Management and Ameriprise from managing, operating and distributing the Funds. The Board took into account JDL’s conclusion that 2014 Columbia Management profitability was reasonable. It also considered that Columbia Management generated 2014 profitability that only moderately exceeded 2013 levels. It was further observed that, based on information presented, 2014 overall profitability is in line with profitability levels of industry competitors. It also took into account the indirect economic benefits flowing to Columbia Management or its affiliates in connection with managing or distributing the Funds, such as the enhanced ability to offer various other financial products to Ameriprise Financial customers, soft dollar benefits and overall reputational advantages. The Board noted that the fees paid by the Funds should permit the Investment Manager to offer competitive compensation to its personnel, make necessary investments in its business and earn an appropriate profit. The Board concluded that profitability levels were reasonable.

Economies of Scale to be Realized

Based on the foregoing, the Board, including all of the Independent Directors, concluded that the investment management services fees were fair and reasonable in light of the extent and quality of services provided. In reaching this conclusion, no single factor was determinative. On June 17, 2015, the Board, including all of the Independent Directors, approved the renewal of the IMS Agreement.

Potential Conflicts of Interest:

Like other investment professionals with multiple clients, a Fund’s portfolio manager(s) may face certain potential conflicts of interest in connection with managing both the Fund and other accounts at the same time. The Investment Manager and the Funds have adopted compliance policies and procedures that attempt to address certain of the potential conflicts that portfolio managers face in this regard. Certain of these conflicts of interest are summarized below.

The management of accounts with different advisory fee rates and/or fee structures, including accounts that pay advisory fees based on account performance (performance fee accounts), may raise potential conflicts of interest for a portfolio manager by creating an incentive to favor higher fee accounts.

Potential conflicts of interest also may arise when a portfolio manager has personal investments in other accounts that may create an incentive to favor those accounts. As a general matter and subject to the Investment Manager’s Code of Ethics and certain limited exceptions, the Investment Manager’s investment professionals do not have the opportunity to invest in client accounts, other than the funds.

A portfolio manager who is responsible for managing multiple funds and/or accounts may devote unequal time and attention to the management of those Funds and/or accounts. The effects of this potential conflict may be more pronounced where Funds and/or accounts managed by a particular portfolio manager have different investment strategies.

A portfolio manager may be able to select or influence the selection of the broker/dealers that are used to execute securities transactions for the Funds. A portfolio manager’s decision as to the selection of broker/dealers could produce disproportionate costs and benefits among the Funds and the other accounts the portfolio manager manages.

A potential conflict of interest may arise when a portfolio manager buys or sells the same securities for a Fund and other accounts. On occasions when a portfolio manager considers the purchase or sale of a security to be in the best interests of a Fund as well as other accounts, the Investment Manager’s trading desk may, to the extent consistent with applicable laws and regulations, aggregate the securities to be sold or bought in order to obtain the best execution and lower brokerage commissions, if any. Aggregation of trades may create the potential for unfairness to a Fund or another account if a portfolio manager favors one account over another in allocating the securities bought or sold. In addition, although the Investment Manager has entered into a personnel sharing arrangement with Threadneedle, the Investment Manager and Threadneedle maintain separate trading operations for their clients. By maintaining separate trading operations in this manner, the Funds may forego certain opportunities including the aggregation of trades across certain accounts managed by Threadneedle. This could result in the Funds competing in the market with one or more accounts managed by Threadneedle for similar trades. In addition, it is possible that the separate trading desks of the Investment Manager and Threadneedle may be on opposite sides of a trade execution for a Fund at the same time.

“Cross trades,” in which a portfolio manager sells a particular security held by a Fund to another account (potentially saving transaction costs for both accounts), could involve a potential conflict of interest if, for example, a portfolio manager is permitted to sell a security from one account to another account at a higher price than an independent third party would pay. The Investment Manager and the Funds have adopted compliance procedures that provide that any transactions between a Fund and another account managed by the Investment Manager are to be made at a current market price, consistent with applicable laws and regulations.

Another potential conflict of interest may arise based on the different investment objectives and strategies of a Fund and other accounts managed by its portfolio manager(s). Depending on another account’s objectives and other factors, a portfolio manager may give advice to and make decisions for a Fund that may differ from advice given, or the timing or nature of decisions made, with respect to another account. A portfolio manager’s investment decisions are the product of many factors in addition to basic suitability for the particular account involved. Thus, a portfolio manager may buy or sell a particular security for certain accounts, and not for a Fund, even though it could have been bought or sold for the Fund at the same time. A portfolio manager also may buy a particular security for one or more accounts when one or more other accounts are selling the security (including short sales). There may be circumstances when a portfolio manager’s purchases or sales of portfolio securities for one or more accounts may have an adverse effect on other accounts, including the Funds.

A Fund’s portfolio manager(s) also may have other potential conflicts of interest in managing the Fund, and the description above is not a complete description of every conflict that could exist in managing the Fund and other accounts. Many of the potential conflicts of interest to which the Investment Manager’s portfolio managers are subject are essentially the same or similar to the potential conflicts of interest related to the Investment Management activities of the Investment Manager and its affiliates.

Structure of Compensation:

Portfolio manager compensation is typically comprised of (i) a base salary and (ii) an annual cash bonus. The annual cash bonus, and in some instances the base salary, are paid from a team bonus pool that is based on fees and performance of the accounts managed by the portfolio management team, which might include mutual funds, wrap accounts, institutional portfolios and hedge funds.

The percentage of management fees on mutual funds and long-only institutional portfolios that fund the bonus pool is based on the short term (typically one-year) and long-term (typically three-year and five-year) performance of those accounts in relation to the relevant peer group universe.

A fixed percentage of management fees on hedge funds and separately managed accounts that follow a hedge fund mandate fund the bonus pool.

The percentage of performance fees on hedge funds and separately managed accounts that follow a hedge fund mandate that fund the bonus pool is based on the absolute level of each hedge fund’s current year investment return.

For all employees the benefit programs generally are the same, and are competitive within the Financial Services Industry. Employees participate in a wide variety of plans, including options in Medical, Dental, Vision, Health Care and Dependent Spending Accounts, Life Insurance, Long Term Disability Insurance, 401(k), and a cash balance pension plan.

Item 9.

Purchases of Equity Securities by Closed-End Management Investment Company and Affiliated Purchasers.

The Fund has a share repurchase plan approved by the Fund’s Board of Directors, which authorizes repurchases of the Fund’s common stock in the open market at times when shares are trading at a discount from NAV and in an amount approximately sufficient to

offset the growth in the number of common shares attributable to the reinvestment of the portion of its distributions to common stockholders attributable to distributions received from portfolio investments less Fund expenses. The Fund has not repurchased shares during the period.

Item 10.

Submission of Matters to a Vote of Security Holders.

There were no material changes to the procedures by which shareholders may recommend nominees to the registrant’s board of directors.

Item 11.

Controls and Procedures.

(a)

The registrant’s principal executive officer and principal financial officers, based on their evaluation of the registrant’s disclosure controls and procedures as of a date within 90 days of the filing of this report, have concluded that such controls and procedures are adequately designed to ensure that material information required to be disclosed by the registrant in Form N-CSR is accumulated and communicated to the registrant’s management, including the principal executive officer and principal financial officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

(b)

There was no change in the registrant’s internal control over financial reporting that occurred during the registrant’s second fiscal quarter of the period covered by this report that has materially affected, or is reasonably likely to materially affect, the registrant’s internal control over financial reporting.
