Item 1. Reports to Stockholders.

A MESSAGE FROM THE PRESIDENT

Dear Fellow Shareholders:

I want to take this opportunity to say thank you for investing in the Hartford HLS Funds. We’ve seen continued market volatility throughout the first half of 2012, and there will likely be continued uncertainty until the Presidential election in November, but we are still optimistic about the markets in 2012.

Market Review

In the first quarter of 2012, the S&P 500 Index turned in its best quarterly performance since the third quarter of 2009. U.S. equities showed signs of improvement as investors focused on improving economic data and strong corporate earnings news and the Federal Reserve’s pledge to keep interest rates low buoyed investors’ appetites.

The second quarter ended on a high note for the stock market—the S&P 500 had its strongest June in more than a decade and the Dow Jones Industrial Average had its best month since October—but those gains weren’t enough to offset losses from April and May, and equities finished the quarter in the red. Although the S&P 500 was -2.75 for the second quarter, it was up 9.49% for the first half of 2012.

Concerns about domestic and European unemployment are having an effect on our economy. The unemployment rate in the euro zone's 17 nations rose to a record 11.1% in May, the highest level since the euro launched as a common currency more than 10 years ago. In the U.S., the labor market has been fickle this year, with job growth starting off strong in the first couple months of 2012 but slowing down in the spring, which has led many to wonder about the status of the economic recovery.

On a positive note, home prices are rising again after falling for more than five years, new and existing home sales are increasing, and home builders are ramping up construction.

The Hartford HLS Funds Expands Relationship with Wellington Management

We’re very pleased that we are expanding our relationship with Wellington Management, which will now serve as the primary sub-adviser for the Hartford HLS Funds including equity, fixed-income,* and asset-allocation funds. One of America’s oldest and largest investment management firms, Wellington Management has resources that span the entire globe, with multiple offices across the U.S. and numerous offices abroad. Wellington Management’s most distinctive strength is its proprietary research, which is shared across the entire organization.

We believe that aligning more closely with a well-respected money manager like Wellington Management puts us in a strong position to drive significant growth and to continue delivering innovative fund strategies to help our investors meet their financial goals.

Thank you again for investing with the Hartford HLS Funds.

James Davey

President

*Several fixed-income funds will continue to be sub-advised by Hartford Investment Management Company.

Notes to Financial Statements

June 30, 2012 (Unaudited)

(000’s Omitted)

Organization:

The Hartford HLS Funds serve as underlying investment options for certain variable annuity and variable life insurance separate accounts of Hartford Life Insurance Company (“HLIC”) and its affiliates and certain qualified retirement plans. Certain Hartford HLS Funds may also serve as underlying investment options for certain variable annuity and variable life separate accounts of other insurance companies. Owners of variable annuity contracts and policyholders of variable life insurance contracts may choose the funds permitted in the variable insurance contract prospectus. In addition, participants in certain qualified retirement plans may choose the funds if permitted by their plans.

Hartford Series Fund, Inc. (the “Company”) is an open-end management investment company comprised of thirty portfolios, eleven portfolios of which are included in these financial statements (each a “Fund” or together the “Funds”). These eleven portfolios of the Company are American Funds Asset Allocation HLS Fund, American Funds Blue Chip Income and Growth HLS Fund, American Funds Bond HLS Fund, American Funds Global Bond HLS Fund, American Funds Global Growth and Income HLS Fund, American Funds Global Growth HLS Fund, American Funds Global Small Capitalization HLS Fund, American Funds Growth HLS Fund, American Funds Growth-Income HLS Fund, American Funds International HLS Fund and American Funds New World HLS Fund.

The Company is organized under the laws of the State of Maryland and is registered with the Securities and Exchange Commission (“SEC”) under the Investment Company Act of 1940, as amended (“1940 Act”). Each Fund is organized as a diversified open-end management investment company, except for American Funds Global Bond HLS Fund, which is non-diversified.

Each Fund operates in the manner of a fund of funds, investing in shares of underlying mutual funds (the “Underlying Funds”). Each Underlying Fund is offered by American Funds Insurance Series, and is a registered open-end investment company. The Funds and their related Underlying Funds are listed below:

Fund		Underlying Fund
American Funds Asset Allocation HLS Fund		Asset Allocation Fund Class 1
American Funds Blue Chip Income and Growth HLS Fund		Blue Chip Income and Growth Fund Class 1
American Funds Bond HLS Fund		Bond Fund Class 1
American Funds Global Bond HLS Fund		Global Bond Fund Class 1
American Funds Global Growth and Income HLS Fund		Global Growth and Income Fund Class 1
American Funds Global Growth HLS Fund		Global Growth Fund Class 1
American Funds Global Small Capitalization HLS Fund		Global Small Capitalization Fund Class 1
American Funds Growth HLS Fund		Growth Fund Class 1
American Funds Growth-Income HLS Fund		Growth-Income Fund Class 1
American Funds International HLS Fund		International Fund Class 1
American Funds New World HLS Fund		New World Fund Class 1

The Underlying Funds’ accounting policies are outlined in the Underlying Funds’ shareholder report, which accompanies this report.

Class IB shares of the Funds are offered at the per share net asset value (“NAV”) without a sales charge and are subject to distribution fees charged pursuant to a Distribution and Service Plan. The Distribution and Service Plan has been adopted in accordance with Rule 12b-1 under the 1940 Act.

Table of Contents

Significant Accounting Policies:

The following is a summary of significant accounting policies of the Funds in the preparation of their financial statements, which are in accordance with the United States Generally Accepted Accounting Principles (“U.S. GAAP”). The preparation of financial statements in accordance with U.S. GAAP may require management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.

Determination of Net Asset Value – The NAV of each class of the Funds’ shares is determined as of the close of regular trading (normally 4:00 p.m. Eastern Time) (the “NYSE Close”) on each day that the New York Stock Exchange (the “Exchange”) is open (“Valuation Date”). Information that becomes known to the Funds after the NAV has been calculated on a particular day will not generally be used to retroactively adjust the NAV determined earlier that day.

Investment Valuation – Investments in the Underlying Funds are valued at the respective NAV of each Underlying Fund as determined as of the NYSE Close on Valuation Date. Valuation of investments held by the Underlying Funds is discussed in Notes to Financial Statements of the Underlying Funds, which are included in the Underlying Funds’ shareholder report, accompanying this report.

U.S. GAAP defines fair value as the price that the Fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants. The U.S. GAAP fair value measurement standards require disclosure of a fair value hierarchy for each major category of assets and liabilities. Various inputs are used in determining the fair value of each Fund’s investments. These inputs are summarized into three broad hierarchy levels. This hierarchy is based on whether the valuation inputs are observable or unobservable. These levels are:

Level 1 – Quoted prices in active markets for identical investments.

Valuation levels are not necessarily indicative of the risk associated with investing in such securities. Individual securities within any of the above mentioned asset classes may be assigned a different hierarchical level than those presented above, as individual circumstances dictate.

During the six-month period ended June 30, 2012, the Funds held no Level 3 securities, therefore no reconciliations of Level 3 securities are presented.

For additional information, refer to the investment valuation hierarchy level summary which follows the Schedule of Investments for each Fund.

For purposes of reporting transfers between different hierarchy levels, both transfers in and out of each level, as applicable, are shown as if they occurred at the beginning of the period.

Income and capital gain distributions from Underlying Funds are recorded on the ex-dividend date.

Fund Share Valuation and Dividend Distributions to Shareholders – Orders for the Funds’ shares are executed in accordance with the investment instructions of the contract holders. The NAV of each Fund’s shares is determined as of the close of each business day of the Exchange. The NAV is determined for each Fund by dividing the Fund’s net assets by the number of shares outstanding. Orders for the purchase of a Fund’s shares received by an insurance company prior to the close of the Exchange on any day on which the Exchange is open for business are priced at the NAV determined as of the close of the Exchange. Orders received by an insurance company after the close of the Exchange, or on a day on which the Exchange and/or the Fund is not open for business, are priced at the next determined NAV.

Dividends are declared pursuant to a policy adopted by the Company’s Board of Directors based upon the investment performance of the Funds The policy of the all Funds is to pay dividends from net investment income and realized capital gains, if any, at least once a year.

Distributions from net investment income, realized capital gains and capital are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP with respect to character and timing. These differences may include but are not limited to losses deferred due to wash sale adjustments and short-term capital gain adjustments. Permanent book and federal income tax basis differences relating to shareholder distributions will result in reclassifications to certain of the Funds’ capital accounts (see Federal Income Taxes: Reclassification of Capital Accounts note).

Principal Risks:

Market Risks – The Fund’s are exposed to the risks of the Underlying Funds in direct proportion to the amount of assets each Fund allocates to each Underlying Fund. The market values of the Underlying Funds may decline due to general market conditions which are not specifically related to a particular fund, such as real or perceived adverse economic conditions or adverse investor sentiment generally.

Federal Income Taxes:

Federal Income Taxes – For federal income tax purposes, the Funds intend to continue to qualify as Regulated Investment Companies (“RIC”) under Subchapter M of the Internal Revenue Code (“IRC”) by distributing substantially all of their taxable net investment income and net realized capital gains to their shareholders and otherwise complying with the requirements of RIC. The Funds have distributed substantially all of their income and capital gains in the prior year and each Fund intends to distribute substantially all of its income and gains prior to the next fiscal year end. Accordingly, no provision for federal income or excise taxes has been made in the accompanying financial statements. Distributions from short-term capital gains are treated as ordinary income distributions for federal income tax purposes.

Net Investment Income (Loss), Net Realized Gains (Losses) – Net investment income (loss) and net realized gains (losses) may differ for financial statement and tax purposes primarily because of losses deferred due to wash sale adjustments and short-term capital gain adjustments. The character of distributions made during the year from net investment income or net realized gains may differ from their ultimate characterization for federal income tax purposes. Also, due to the timing of dividend distributions, the fiscal year in which amounts are distributed may differ from the year that the net investment income (loss) or net realized gains (losses) were recorded by a Fund.

Table of Contents

Distributions and Components of Distributable Earnings – The tax character of distributions paid by the Funds for the periods indicated is as follows (as adjusted for dividends payable):

	For the Year Ended December 31, 2011						For the Year Ended December 31, 2010

(a)

The Funds designate these distributions as long-term capital dividends per IRC code Sec. 852(b) (3) (C).

As of December 31, 2011, the components of distributable earnings (deficit) on a tax basis were as follows:

	Undistributed Ordinary Income		Undistributed Long-Term Capital Gain		Accumulated Capital and Other Losses			Unrealized Appreciation (Depreciation)@		Total Accumulated Earnings (Deficit)
American Funds Asset Allocation HLS Fund	$	1,026	$	140	$	–		$	6,911	$	8,077
American Funds Blue Chip Income and Growth HLS Fund		467		267		–			5,087		5,821

American Funds Growth HLS Fund		1,116		973		–			69,677		71,766

American Funds International HLS Fund		3,474		–		(426	)		4,750		7,798
American Funds New World HLS Fund		835		2,795		–			4,236		7,866

The difference between book-basis and tax-basis unrealized appreciation (depreciation) is attributable primarily to the tax deferral of wash sale losses.

Reclassification of Capital Accounts – The Funds may record reclassifications in their capital accounts. These reclassifications have no impact on the total net assets of the Funds. The reclassifications are a result of permanent differences between U.S. GAAP and tax accounting for such items as net operating losses that reduce distribution requirements. Adjustments are made to reflect the impact these items have on current and future distributions to shareholders. Therefore, the source of a Fund’s distributable income may be shown in the accompanying Statement of

Assets and Liabilities as from net investment income, from net realized gains on investments or from capital depending on the type of book and tax differences that exist. For the year ended December 31, 2011, the Funds recorded the following reclassifications to increase (decrease) the accounts listed below.

		Net Investment Income				Net Realized Gain (Loss)				Paid-in- Capital
American Funds Global Bond HLS Fund		$	16			$	(16	)		$	–

Capital Loss Carryforward – On December 22, 2010, the Regulated Investment Company Modernization Act of 2010 (the “Act”) was enacted, which made changes to the capital loss carryforward rules. The changes are effective for taxable years beginning after the date of enactment. Under the Act, funds are permitted to carry forward capital losses for an unlimited period. However, any losses incurred during those future taxable years will be required to be utilized prior to the losses incurred in pre-enactment taxable years, which carry an expiration date. As a result of this ordering rule, pre-enactment capital loss carryforwards may be more likely to expire unused. Additionally, post-enactment capital loss carryforwards retain their character as either short-term or long-term capital losses rather than being considered all short-term as permitted under prior regulation.

At December 31, 2011 (tax-year-end), the Funds had capital loss carryforwards for U.S. federal income tax purposes as follows:

Capital loss carryforwards with expiration:

	2012		2013		2014		2015		2016		2017		2018		Total
American Funds Global Growth and Income HLS Fund	$	—	$	—	$	—	$	—	$	—	$	—	$	1,457	$	1,457

American Funds Growth HLS Fund		848
American Funds New World HLS Fund		209

Accounting for Uncertainty in Income Taxes – The Funds have adopted financial reporting rules that require the Funds to analyze all open tax years, as defined by the Statute of Limitations, for all major jurisdictions. Generally, tax authorities can examine all tax returns filed for the last three years. The Funds do not have an examination in progress.

Table of Contents

The Funds have reviewed all open tax years and major jurisdictions and concluded that these financial reporting rules have no effect on the Funds’ financial positions or results of operations. There is no tax liability resulting from unrecognized tax benefits relating to uncertain income tax positions taken or expected to be taken on the tax returns for the fiscal year-end December 31, 2011. The Funds are also not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months.

Expenses:

The schedule below reflects the rates of compensation as a percentage of each Fund’s average daily net assets paid to HL Advisors for investment management services rendered during the six-month period ended June 30, 2012. The rates are accrued daily and paid monthly:

Fund	Annual Rate*
American Funds Asset Allocation HLS Fund		0.65	%
American Funds Blue Chip Income and Growth HLS Fund		0.75	%
American Funds Bond HLS Fund		0.50	%
American Funds Global Bond HLS Fund		0.75	%
American Funds Global Growth and Income HLS Fund		0.80	%
American Funds Global Growth HLS Fund		1.00	%
American Funds Global Small Capitalization HLS Fund		0.80	%
American Funds Growth HLS Fund		0.75	%
American Funds Growth-Income HLS Fund		0.70	%
American Funds International HLS Fund		0.85	%
American Funds New World HLS Fund		1.10	%

HL Advisors has entered into an agreement under which it will waive a portion of its investment management fee with respect to each Fund for as long as that Fund is invested in its corresponding Underlying Fund. The net investment management fee under the agreement with HL Advisors, after giving effect to the waiver, is 0.25% of the average daily net assets for each Fund.

Accounting Services Agreement – Pursuant to the Fund Accounting Agreement between HLIC and the Company, on behalf of the Funds, HLIC provides accounting services to the Funds and receives monthly compensation of 0.01% of each Fund’s average daily net assets. These fees are accrued daily and paid monthly.

Other Related Party Transactions – Certain officers of the Funds are directors and/or officers of HL Advisors and/or The Hartford or its subsidiaries. For the six-month period ended June 30, 2012, a portion of the Funds’ chief compliance officer’s salary was paid by all the investment companies in the Hartford fund complex. The portion allocated to the Funds was in the amount of $1. These fees are accrued daily and paid monthly.

Operating Expenses – Allocable expenses incurred by the Company are allocated to each Fund in proportion to the average daily net assets of each Fund, except where allocation of certain expenses is more fairly made directly to the Fund.

Distribution Plan for Class IB shares – The Company, on behalf of the Funds, has adopted a Distribution Plan pursuant to Rule 12b-1 of the 1940 Act to compensate the Distributor, Hartford Securities Distribution Company, Inc. (a wholly owned, ultimate subsidiary of The Hartford), from assets attributable to the Class IB shares for services rendered and

Notes to Financial Statements – (continued)

June 30, 2012 (Unaudited)

(000’s Omitted)

expenses borne in connection with activities primarily intended to result in the sale of the Class IB shares, subject to the review and approval of the Company’s Board of Directors.

The Distribution Plan provides that the Fund may pay annually up to 0.25% of the average daily net assets of the Fund attributable to its Class IB shares for activities primarily intended to result in the sale of Class IB shares. The Board has the authority to suspend or reduce these payments at any point in time. Under the terms of the Distribution Plan and the principal underwriting agreement, each Fund is authorized to make payments monthly to the Distributor that may be used to pay or compensate entities providing distribution and shareholder servicing with respect to the Class IB shares for such entities’ fees or expenses incurred or paid in that regard. These fees are accrued daily and paid monthly.

Line of Credit:

The Funds, along with several other Hartford funds, participate in a $500 million committed revolving line of credit facility. The facility is to be used for temporary or emergency purposes. Under the arrangement, a fund is required to own securities having a market value in excess of 300% of the total bank borrowings. The interest rate on borrowings varies depending on the nature of the loan. The facility also requires a fee to be paid based on the amount of the commitment. This commitment fee is allocated to all the funds participating in the line of credit based on the average net assets of the funds. During the six-month period ended June 30, 2012, the Funds did not have any borrowings under this facility.

Indemnifications:

Under the Company’s organizational documents, the Company shall indemnify its officers and directors to the full extent required or permitted under Maryland General Corporation Law and the federal securities laws. In addition, the Company, on behalf of the Fund, may enter into contracts that contain a variety of indemnifications. The Company’s maximum exposure under these arrangements is unknown. However, as of the date of these financial statements, the Company has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.

Expense Example (Unaudited)

Your Fund's Expenses

As a shareholder of a Fund, you incur two types of costs: (1) transaction costs and (2) ongoing costs including investment management fees, distribution fees, and other fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in a Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the period of December 31, 2011 through June 30, 2012.

Actual Expenses

The first set of columns of the table below provides information about actual account values and actual expenses. You may use the information in this column, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the line under the heading entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second set of columns of the table below provides information about hypothetical account values and hypothetical expenses based on a Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in a Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) and CDSC. Therefore, the second set of columns of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would be higher. Expenses are equal to the Fund's annualized expense ratios multiplied by average account value over the period, multiplied by 182/366 (to reflect the one-half year period).

Portfolio Managers
John C. Keogh	Karen H. Grimes, CFA*
Senior Vice President and Fixed Income Portfolio Manager	Senior Vice President and Equity Portfolio Manager

* Appointed as a Portfolio Manager for the Fund as of April 30, 2012. As of the same date, Steven T. Irons and Peter I. Higgins no longer serve as portfolio managers for the Fund.

How did the Fund perform?

The Class IA shares of the Hartford Balanced HLS Fund returned 6.05% for the six-month period ended June 30, 2012, underperforming its blended benchmark, 60% S&P 500 Index, 35% Barclays U.S. Government/Credit, and 5% 90 day Treasury Bill, which returned 6.71% for the same period. The Fund underperformed the 6.19% return of the average fund in the Lipper Mixed-Asset Target Allocation Growth VP-UF Funds peer group, a group of funds that hold between 60%-80% in equity securities, with the remainder invested in bonds, cash, and cash equivalents.

Why did the Fund perform this way?

U.S. equities rose at the start of the year based on improving macroeconomic data including employment data and consumer confidence. Following a strong first quarter, equities retreated in April, fell sharply in May, and recovered modestly in June. Fears surrounding European sovereign debt took center stage. Equity markets as measured by the S&P 500 returned 9.48% during the period. Telecommunication Services (+17%), Financials (+14%), and Information Technology (+13%) posted the largest gains while Energy (-2%) was the only sector to post a negative absolute (i.e. total return) performance return.

The bond market, as measured by the Barclays Government/Credit Bond Index, returned 2.65% during the period. All risk segments of the fixed income market outperformed duration-equivalent Treasuries for the period.

The Fund has three primary levers to generate investment performance: equity investments, fixed income investments, and asset allocation among stocks, bonds, and cash. During the period, the equity portion of the Fund underperformed its benchmark, while the fixed income portion of the Fund outperformed its benchmark. Asset allocation contributed positively to benchmark-relative results as the Fund was generally overweight in equities and underweight in fixed income and cash relative to the benchmark.

Equity underperformance versus the benchmark was driven by security selection, which was weakest in Information Technology, Financials, and Consumer Staples. This was partially offset by stronger selection in Consumer Discretionary. Sector positioning, which is a result of bottom-up (i.e. stock by stock fundamental research) security selection, contributed positively to relative performance due to an overweight (i.e. the Fund’s sector position was greater than the benchmark position) to Information Technology and underweight exposure to Utilities.

Stocks that detracted the most from relative returns (i.e. performance of the Fund as measured against the benchmark) in the equity portion of the Fund during the period were Google (Information Technology), Western Union (Information Technology), and Hewlett-Packard (Information Technology). Google, a leading provider of online search, internet content services, and web-based software applications, saw its shares decline in the face of a potential slow down in advertising expenditure in a lower global growth environment. Shares of U.S.-based global money transfer and payments company Western Union fell after the company issued lower-than-expected earnings guidance. Shares of Hewlett-Packard, a computer and technology provider, declined after the company issued first quarter results that included declining revenues in its key commercial printing segment and near-term earnings guidance that was below analysts’ expectations in the midst of economic uncertainty in Europe. Anadarko Petroleum (Energy) also detracted from the Fund’s returns on an absolute basis.

Top contributors to relative performance of the equity portion of the Fund during the period were Harley-Davidson (Consumer Discretionary), Ingersoll-Rand (Industrials), and eBay (Information Technology). Motorcycle manufacturer Harley-Davidson saw its shares rise in the first four months of the year as it announced strong earnings which exceeded expectations. Shares of Ingersoll-Rand, a provider of industrial machinery, climate control systems and security products, surged higher after residential markets strengthened and the company beat consensus fourth quarter earnings estimates. Shares of eBay, a U.S.-based global provider of online marketplaces and payment solutions, rose after the company reported better-than-expected first quarter results due to strong growth in its marketplace segment and higher

transaction margins in the payments segment. Apple (Information Technology), Wells Fargo (Financials), and Comcast (Consumer Discretionary) also contributed positively to the Fund’s returns on an absolute basis.

The fixed income portion of the Fund outperformed its benchmark during the period. Security selection within the Investment Grade corporate bond sector was the primary driver of the outperformance. An allocation to agency mortgage-backed securities (MBS) was also modestly additive. Our duration and yield curve positioning had minimal impact on relative performance. Despite a challenging second quarter due to the escalation of the European sovereign debt crisis, investment grade corporate bonds posted strong performance for the period. Outperformance came during the first quarter, in reaction to the release of encouraging U.S. economic releases and some positive developments out of Europe. Within the sector, financials benefitted early on from the confidence-boosting Long Term Refinancing Operation in Europe which alleviated liquidity and funding concerns for European financial firms in general. The Fund’s overweight to Financials, particularly Banks, was a positive for relative performance. The Fund held an allocation to the agency MBS sector based on what we considered attractive valuations. Market expectations of additional MBS purchases by the Federal Reserve under any future quantitative easing program seemed to have helped agency MBS to outperform.

What is the outlook?

We expect global economic growth to continue, but at a subpar recovery rate and with varying degrees of recovery by region. Investor focus on potential problem areas, such as the European debt crisis and a slowdown in China, are likely to generate a moderate level of volatility, particularly in a low-growth environment.

Within the equity portion of the Fund we continue to focus our efforts on stock-by-stock fundamental research to construct a diversified large-cap core portfolio. We look for stocks of what we believe are financially sound but out-of-favor companies that provide above-average potential total returns and sell at below-average price/earnings multiples. At the end of the period, our bottom-up investment approach resulted in the largest overweight exposures in Information Technology, Health Care, and Energy. The largest underweights of the equity portion of the Fund to the S&P 500 were in Industrials, Consumer Staples, and Utilities.

Overall within the fixed income portion of the Fund, we are tactically managing the Fund’s duration around neutral and are positioned for a flattening yield curve. We continue to be positioned with an underweight to the Government sector, as we believe that there are more compelling opportunities in other sectors. We believe that corporate fundamentals remain strong, financial companies have de-levered significantly, and that communications issuers have solid balance sheets. We also maintained our overweight posture to the corporate sector at the end of the period. We also maintained our modest allocation to agency MBS.

The equity and fixed income managers will continue to work collaboratively to make decisions regarding portfolio weights in stocks, bonds, and cash. As of June 30, 2012, the Fund’s equity exposure was at 67% compared to 60% in its benchmark and at the upper end of the Fund’s 50-70% range.

The preparation of financial statements in accordance with U.S. GAAP may require management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.

Determination of Net Asset Value – The NAV of each class of the Fund’s shares is determined as of the close of regular trading (normally 4:00 p.m. Eastern Time) (the “NYSE Close”) on each day that the New York Stock Exchange (the “Exchange”) is open (“Valuation Date”). Information that becomes known to the Fund after the NAV has been calculated on a particular day will not generally be used to retroactively adjust the NAV determined earlier that day.

Investment Valuation and Fair Value Measurements – For purposes of calculating the NAV, portfolio investments and other assets held by the Fund's portfolio for which market quotes are readily available are valued at market value. Market value is generally determined on the basis of last reported sales prices or official close price. If no sales are reported, market value is based on quotes obtained from a quotation reporting system, established market makers, or independent pricing services. If market prices are not readily available or are deemed unreliable, the Fund will use the fair value of the investment as determined in good faith under policies and procedures established by and under the supervision of the Company’s Board of Directors. Market quotes are considered not readily available where there is an absence of current or reliable market-based data (e.g., trade information or broker quotes), including where events occur after the close of the relevant market, but prior to the NYSE Close that materially affect the values of the Fund’s portfolio investments or assets. In addition, market quotes are considered not readily available when, due to extraordinary circumstances, the exchanges or markets on which the investments trade do not open for trading for the entire day and no other market prices are available. In addition, prices of foreign equities that are principally traded on certain foreign markets are adjusted daily pursuant to a fair value pricing service approved by the Board of Directors in order to reflect an adjustment for the factors occurring after the close of certain foreign markets but before the NYSE Close. Investments that are primarily traded on foreign markets may trade on days that are not business days of the Fund. The value of the

Table of Contents

foreign investments in which the Fund invests may change on days when a shareholder will not be able to purchase or redeem shares of the Fund. Fair value pricing is subjective in nature and the use of fair value pricing by the Fund may cause the NAV of its shares to differ significantly from the NAV that would have been calculated using market prices at the close of the exchange on which a portfolio investment is primarily traded. There can be no assurance that the Fund could obtain the fair market value assigned to an investment if the Fund were to sell the investment at approximately the time at which the Fund determines its NAV.

Fixed income investments (other than short term obligations) and non-exchange traded derivatives held by the Fund are normally valued on the basis of quotes obtained from brokers and dealers or independent pricing services in accordance with procedures established by the Company’s Board of Directors. Prices obtained from independent pricing services use information provided by market makers or estimates of market values obtained from yield data relating to investments with similar characteristics. Generally, the Fund may use fair valuation in regard to fixed income investments when the Fund holds defaulted or distressed investments or investments in a company in which a reorganization is pending. Short-term investments maturing in 60 days or less are generally valued at amortized cost, if their original term to maturity was 60 days or less, or by amortizing their value on the 61st day prior to maturity, if the original term to maturity exceeded 60 days.

Exchange traded options, futures and options on futures are valued at the settlement price determined by the relevant exchange as of the NYSE Close. If such instruments do not trade on an exchange, values may be supplied by an independent pricing service using a formula or other objective method that may take into consideration the style, direction, expiration, strike price, notional value and volatility or other adjustments.

Investments valued in currencies other than U.S. dollars are converted to U.S. dollars using exchange rates obtained from independent pricing services for calculation of the NAV. As a result, the NAV of the Fund’s shares may be affected by changes in the value of currencies in relation to the U.S. dollar. The value of investments traded in markets outside the United States or denominated in currencies other than the U.S. dollar may be affected significantly on a day that the NYSE is closed and the market value may change on days when an investor is not able to purchase, redeem or exchange shares of the Fund.

Foreign currency contracts represent agreements to exchange currencies on specific future dates at predetermined rates. Foreign currency contracts are valued using foreign currency exchange rates and forward rates as provided by an independent pricing service on the Valuation Date.

Financial instruments for which prices are not available from an independent pricing service may be valued using market quotations obtained from one or more dealers that make markets in the respective financial instrument in accordance with procedures established by the Company’s Board of Directors.

U.S. GAAP defines fair value as the price that the Fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants. The U.S. GAAP fair value measurement standards require disclosure of a fair value hierarchy for each major category of assets and liabilities. Various inputs are used in determining the fair value of the Fund’s investments. These inputs are summarized into three broad hierarchy levels. This hierarchy is based on whether the valuation inputs are observable or unobservable. These levels are:

Level 1 – Quoted prices in active markets for identical investments. Level 1 may include exchange traded instruments, such as domestic equities, some foreign equities, options, futures, mutual funds, exchange traded funds, rights and warrants.

traded on certain foreign markets and are adjusted daily pursuant to a fair value pricing service in order to reflect an adjustment for the factors occurring after the close of certain foreign markets but before the NYSE Close; and short-term investments, which are valued at amortized cost.

Level 3 – Significant unobservable inputs that are supported by limited or no market activity. Level 3 may include financial instruments whose values are determined using indicative market quotes or require significant management judgment or estimation. These unobservable valuation inputs may include estimates for current yields, maturity/duration, prepayment speed, and indicative market quotes for comparable investments along with other assumptions relating to credit quality, collateral value, complexity of the investment structure, general market conditions and liquidity. This category may include investments where trading has been halted or there are certain restrictions on trading. While these investments are priced using unobservable inputs, the valuation of these investments reflects the best available data and management believes the prices are a reasonable representation of exit price.

The Board of Directors of the Company generally reviews and approves the “Procedures for Valuation of Portfolio Securities” on an annual basis. These procedures define how investments are to be valued, including the formation of a Valuation Committee. The Valuation Committee is responsible for determining in good faith the fair value of investments when the value cannot be obtained from primary pricing services or alternative sources or if the valuation of an investment as provided by the primary pricing service or alternative source is believed not to reflect the investment’s fair value as of the Valuation Date. Members of the Valuation Committee include the Fund’s Treasurer or designee, a Vice President of the Funds with legal expertise or designee, and a Vice President of the investment manager or designee. In addition, the Fund’s chief compliance officer shall designate a member of the compliance group to attend Valuation Committee meetings as a non-voting resource, to monitor for and provide guidance with respect to compliance with these procedures. Two members of the Valuation Committee or their designees, representing different departments, shall constitute a quorum for purposes of permitting the Valuation Committee to take action. The Valuation Committee will consider all relevant factors in determining an investment’s fair value, and may seek the advice of the Fund’s sub-adviser, knowledgeable brokers and legal counsel in making such determination. The Valuation Committee reports to the Audit Committee of the Company’s Board of Directors. The Audit Committee receives quarterly written reports which include details of all fair-valued investments, including the reason for the fair valuation, and an indication, when possible, of the accuracy of the valuation by disclosing the next available reliable public price quotation or the disposition price of such investments (the “look-back” test). The Board of Directors then must consider for ratification all of the fair value determinations made during the previous quarter.

Valuation levels are not necessarily indicative of the risk associated with investing in such investments. Individual investments within any of the above mentioned asset classes may be assigned a different hierarchical level than those presented above, as individual circumstances dictate.

For additional information, refer to the Investment Valuation Hierarchy Level Summary and the Level 3 roll-forward reconciliation which follow the Schedule of Investments.

For purposes of reporting transfers between different hierarchy levels, both transfers in and out of each level, as applicable, are shown as if they occurred at the beginning of the period.

Investment Transactions and Investment Income – Investment transactions are recorded as of the trade date (the date the order to buy or sell is executed) for financial reporting purposes. Investments purchased or sold on a when-issued or delayed-delivery basis may be settled a month or more after the trade date. Realized gains and losses are determined on the basis of identified cost.

Table of Contents

amortization of premium and accretion of discounts, is accrued on a daily basis. Paydown gains and losses on mortgage-related and other asset-backed securities are included in interest income in the Statement of Operations.

Foreign Currency Transactions – Assets and liabilities denominated in currencies other than U.S. dollars are translated into U.S. dollars at the exchange rates in effect on the valuation date. Purchases and sales of investments, income, and expenses are translated into U.S. dollars at the exchange rates on the dates of such transactions.

The Fund does not isolate that portion of portfolio investment valuation resulting from fluctuations in the foreign currency exchange rates from the fluctuations arising from changes in the market prices of investments held. Exchange rate fluctuations are included with the net realized and unrealized gain or loss on investments in the accompanying financial statements.

Net realized foreign exchange gains or losses arise from sales of foreign currencies and the difference between asset and liability amounts initially stated in foreign currencies and the U.S. dollar value of the amounts actually received or paid. Net unrealized foreign exchange gains or losses arise from changes in the value of other assets and liabilities at the end of the reporting period, resulting from changes in the exchange rates.

Joint Trading Account – The Fund may invest cash balances into a joint trading account that may be invested in one or more repurchase agreements.

Fund Share Valuation and Dividend Distributions to Shareholders – Orders for the Fund’s shares are executed in accordance with the investment instructions of the contract holders and plan participants. The NAV of the Fund’s shares is determined as of the close of business on each business day of the Exchange. The NAV is determined separately for each class of shares of the Fund by dividing the Fund’s net assets attributable to that class by the number of shares of the class outstanding. Each class of shares offered by the Fund has equal rights as to assets and voting privileges (except that shareholders of a class have exclusive voting rights regarding any matter relating solely to that class of shares). Income and non-class specific expenses are allocated daily to each class on the basis of the relative net assets of the class. Realized and unrealized capital gains and losses are allocated daily based on the relative net assets of each class of shares of the Fund.

Orders for the purchase of the Fund’s shares received prior to the close of the Exchange on any day the Exchange is open for business are priced at the NAV determined as of the close of the Exchange. Orders received after the close of the Exchange, or on a day on which the Exchange and/or the Fund is not open for business, are priced at the next determined NAV.

Dividends are declared pursuant to a policy adopted by the Company’s Board of Directors based upon the investment performance of the Fund. The policy of the Fund is to pay dividends from net investment income and realized capital gains, if any, at least once a year.

Distributions from net investment income, net realized capital gains and capital are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP with respect to character and timing. These differences may include but are not limited to losses deferred due to wash sale adjustments, foreign currency gains and losses, adjustments related to Passive Foreign Investment Companies (“PFICs”), Real Estate Investment Trusts (“REITs”), Regulated Investment Companies (“RICs”), certain derivatives and partnerships. Permanent book and federal income tax basis differences relating to shareholder distributions will result in reclassifications to certain of the Fund’s capital accounts (see Federal Income Taxes: Reclassification of Capital Accounts note).

Securities and Other Investments:

Repurchase Agreements – A repurchase agreement is an agreement by which a counterparty agrees to sell an investment and agrees to repurchase the investment sold at a mutually agreed upon time and price. At the time the Fund enters into a repurchase agreement, the value of the underlying collateral, including accrued interest, will be equal to or exceed the value of the repurchase agreement. Repurchase agreements expose the Fund to counterparty risk. To minimize counterparty risk, the investments that serve to collateralize the repurchase agreement are held by the Fund’s custodian in book entry or physical form in the custodial account of the Fund or in a third party custodial account. Repurchase agreements are valued at cost plus accrued interest. The Fund, as shown on the Schedule of Investments, had outstanding repurchase agreements as of June 30, 2012.

Illiquid and Restricted Investments – The Fund is permitted to invest up to 15% of its net assets in illiquid investments. Illiquid investments are those that may not be sold or disposed of in the ordinary course of business within seven days, at approximately the price used to determine the Fund’s NAV. The Fund may not be able to sell illiquid investments when its sub-adviser considers it desirable to do so or may have to sell such investments at a price that is lower than the price that could be obtained if the investments were more liquid. A sale of illiquid investments may require more time and may result in higher dealer discounts and other selling expenses than does the sale of those that are liquid. Illiquid investments also may be more difficult to value due to the unavailability of reliable market quotations for such investments, and an investment in them may have an adverse impact on the Fund’s NAV. The Fund may also purchase certain restricted investments that can only be resold to certain qualified investors and may be determined to be liquid pursuant to policies and guidelines established by the Company’s Board of Directors. The Fund, as shown on the Schedule of Investments, had illiquid and/or restricted investments as of June 30, 2012.

Investments Purchased on a When-Issued or Delayed-Delivery Basis – Delivery and payment for investments that have been purchased by the Fund on a forward commitment, or when-issued or delayed-delivery basis, take place beyond the customary settlement period. A fund may dispose of or renegotiate a delayed-delivery transaction after it is entered into, and may sell delayed-delivery investments before they are delivered, which may result in a realized gain or loss. During this period, such investments are subject to market fluctuations, and the Fund identifies investments segregated in its records with a value at least equal to the amount of the commitment. The Fund, as shown on the Schedule of Investments, had when-issued or delayed delivery investments as of June 30, 2012.

In connection with the Fund’s ability to purchase investments on a when-issued or forward commitment basis, the Fund may enter into to-be announced (“TBA”) commitments. TBA commitments are forward agreements for the purchase or sale of mortgage-backed securities for a fixed price, with payment and delivery on an agreed-upon future settlement date. The specific securities to be delivered are not identified at the trade date; however, delivered securities must meet specified terms, including issuer, rate and mortgage terms. The Fund generally enters into TBA commitments with intent to take possession of or deliver the underlying mortgage-backed securities but can extend the settlement or roll the transaction. In a TBA roll, the Fund generally purchases or sells the initial TBA commitment prior to the stipulated settlement date and enters into a new TBA commitment for future delivery or receipt of the mortgage-backed securities. TBA commitments involve a risk of loss if the value of the security to be purchased or sold declines or increases, respectively, prior to settlement date.

The Fund may enter into “dollar rolls” in which the Fund sells securities and contracts with the same counterparty to repurchase substantially similar securities (for example, same issuer, coupon and maturity) on a specified future date at an agreed upon price. The Fund gives up the right to receive interest paid on the investments sold. The Fund would benefit to the extent of any differences between the price received for the security and the lower forward price for the future purchase. Dollar rolls involve the risk that the market value of the securities that the Fund is required to purchase may decline below the agreed upon repurchase price of those securities. The Fund accounts for dollar roll transactions as purchases and sales and realizes gains and losses on these transactions. These transactions are excluded from the Fund’s portfolio turnover rate. The Fund had open dollar roll transactions as of June 30, 2012, as disclosed on the Schedule of Investments, the Statement of Assets and Liabilities and the Statement of Operations.

Table of Contents

Mortgage Related and Other Asset Backed Securities – The Fund may invest in mortgage related and other asset backed securities. These securities include mortgage pass-through securities, collateralized mortgage obligations, commercial mortgage backed securities, stripped mortgage backed securities, asset backed securities, collateralized debt obligations and other securities that directly or indirectly represent a participation in, or are secured by and payable from, mortgage loans on real property. Mortgage related securities are created from pools of residential or commercial mortgage loans, including mortgage loans made by savings and loan institutions, mortgage bankers, commercial banks and others. Asset backed securities are created from many types of assets, including auto loans, credit card receivables, home equity loans, and student loans. These securities provide a monthly payment which consists of both interest and principal payments. Interest payments may be determined by fixed or adjustable rates. The rate of pre-payments on underlying mortgages will affect the price and volatility of a mortgage related security, and may have the effect of shortening or extending the effective duration of the security relative to what was anticipated at the time of purchase. The timely payment of principal and interest of certain mortgage related securities is guaranteed by the full faith and credit of the United States Government. Pools created and guaranteed by non-governmental issuers, including government-sponsored corporations, may be supported by various forms of insurance or guarantees, but there can be no assurance that the private insurers or guarantors can meet their obligations under the insurance policies or guarantee arrangements. The Fund, as shown on the Schedule of Investments, had mortgage related and other asset backed securities as of June 30, 2012.

Financial Derivative Instruments:

The following disclosures contain information on how and why the Fund uses derivative instruments, the credit-risk-related contingent features in certain derivative instruments, and how derivative instruments affect the Fund’s financial position and results of operations. The location and fair value amounts of these instruments on the Statement of Assets and Liabilities and the realized gains and losses and changes in unrealized gains and losses on the Statement of Operations, each categorized by type of derivative contract, are included in the following Additional Derivative Instrument Information footnote. The derivative instruments outstanding as of period-end are disclosed in the notes to the Schedule of Investments and the amounts of realized gains and losses and changes in unrealized gains and losses on derivative instruments during the period are disclosed in the Statement of Operations.

Foreign Currency Contracts – The Fund may enter into foreign currency contracts that obligate the Fund to purchase or sell currencies at specified future dates. Foreign currency contracts are used to hedge the currency exposure associated with some or all of the Fund’s investments and/or as part of an investment strategy. Foreign currency contracts are marked to market daily and the change in value is recorded by the Fund as an unrealized gain or loss. The Fund will record a realized gain or loss when the foreign currency contract is settled.

Foreign currency contracts involve elements of market risk in excess of the amounts reflected in the Statement of Assets and Liabilities. In addition, risks may arise upon entering into these contracts from the potential inability of the counterparties to meet the terms of the contracts and from unanticipated movements in the value of the foreign currencies relative to the U.S. dollar. The Fund had no outstanding foreign currency contracts as of June 30, 2012.

Futures Contracts – The Fund may enter into futures contracts. A futures contract is an agreement between two parties to buy or sell an asset at a set price on a future date. The Fund uses futures contracts to manage or obtain exposure to the investment markets, commodities, or movements in interest rates and currency values. The primary risks associated with the use of futures contracts are the imperfect correlation between the change in market value of the investments held by the Fund and the prices of futures contracts and the possibility of an illiquid market. Upon entering into a futures contract, the Fund is required to deposit with a futures commission merchant (“FCM”) an amount of cash or U.S. Government or Agency Obligations in accordance with the initial margin requirements of the broker or exchange. Futures contracts are marked to market daily at the most recent settlement price reported by an exchange on which, over time, they are traded most extensively, and an appropriate payable or receivable for the change in value (“variation margin”) is recorded by the Fund. Gains or losses are recognized but not considered realized until the contracts expire or are closed. Futures contracts involve, to varying degrees, risk of loss in excess of the variation margin disclosed on the

Statement of Assets and Liabilities; however, this risk is reduced through the use of an FCM. As of June 30, 2012, the Fund had no outstanding futures contracts.

Total	$	—		$	(147	)	$	—	$	—	$	—	$	—	$	(147	)

Principal Risks:

Credit and Counterparty Risks – Credit risk depends largely on the perceived financial health of bond issuers. In general, the credit rating is inversely related to the credit risk of the issuer. Higher rated bonds generally are deemed to have less credit risk, while lower or unrated bonds are deemed to have higher risk of default. The share price, yield and total return of a fund that holds securities with higher credit risk may be more volatile than those of a fund that holds bonds with lower credit risk. Similar to credit risk, the Fund may be exposed to counterparty risk, or the risk that an institution or other entity with which the Fund has unsettled or open transactions will default.

Market Risks – The Fund’s investments expose the Fund to various risks including, but not limited to, interest rate, prepayment, extension, foreign currency, and equity risks. Interest rate risk is the risk that fixed income securities will decline in value because of changes in interest rates. As nominal interest rates rise, the values of certain fixed income securities held by the Fund are likely to decrease. A nominal interest rate can be described as the sum of a real interest rate and an expected inflation rate. Fixed income securities with longer durations tend to be more sensitive to changes in interest rates, usually making them more volatile than securities with shorter durations. Duration is useful primarily as a measure of the sensitivity of a fixed income security’s market price to interest rate (i.e., yield) movements. In addition, securities are subject to extension risk. Rising interest rates may cause prepayments to occur at a slower than expected rate, thereby effectively lengthening the maturity of the security and making the security more sensitive to interest rate changes. Prepayment and extension risk are major risks of mortgage-backed securities and certain asset-backed securities. For certain asset-backed securities, the actual maturity may be less than the stated maturity shown in the Schedule of Investments, if applicable. As a result, the timing of income recognition relating to these securities may vary based upon the actual maturity. If the Fund invests directly in foreign currencies or in securities that trade in, and receive revenues in, foreign currencies, or in derivatives that provide exposure to foreign currencies, it will be subject to the risk that those currencies will decline in value relative to the base currency of the Fund, or, in the case of hedging positions, that the Fund’s base currency will decline in value relative to the currency being hedged. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates, intervention (or the failure to intervene) by U.S. or foreign governments, central banks or supranational entities, such as the International Monetary Fund, or by the imposition of currency controls or other political developments in the United States or abroad. As a result, the Fund’s investments in foreign currency denominated securities may reduce the returns of the Fund. The market values of equity securities, such as common stocks and preferred stocks, or equity

Table of Contents

related investments, such as futures and options, may decline due to general market conditions which are not specifically related to a particular company, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The market value of equity securities may also decline due to factors which affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry. Equity securities and equity related investments generally have greater market price volatility than fixed income securities.

Federal Income Taxes:

Federal Income Taxes – For federal income tax purposes, the Fund intends to continue to qualify as a RIC under Subchapter M of the Internal Revenue Code (“IRC”) by distributing substantially all of its taxable net investment income and net realized capital gains to its shareholders and otherwise complying with the requirements of RICs. The Fund has distributed substantially all of its income and capital gains in prior years, if applicable, and intends to distribute substantially all of its income and capital gains prior to the next fiscal year-end. Accordingly, no provision for federal income or excise taxes has been made in the accompanying financial statements. Distributions from short-term capital gains are treated as ordinary income distributions for federal income tax purposes.

Net Investment Income (Loss), Net Realized Gains (Losses) – Net investment income (loss) and net realized gains (losses) may differ for financial statement and tax purposes primarily because of losses deferred due to wash sale adjustments, foreign currency gains and losses, adjustments related to PFICs, REITs, RICs, certain derivatives and partnerships. The character of distributions made during the year from net investment income or net realized gains may differ from their ultimate characterization for federal income tax purposes. Also, due to the timing of dividend distributions, the fiscal year in which amounts are distributed may differ from the year that the income or realized gains (losses) were recorded by the Fund.

Distributions and Components of Distributable Earnings – The tax character of distributions paid by the Fund for the periods indicated is as follows (as adjusted for dividends payable):

		For the Year Ended December 31, 2011				For the Year Ended December 31, 2010
Ordinary Income		$	57,855			$	55,000

As of December 31, 2011, the Fund’s components of distributable earnings (deficit) on a tax basis were as follows:

	Amount
Undistributed Ordinary Income	$	28,105
Accumulated Capital and Other Losses*		(1,080,774	)
Unrealized Appreciation†		245,065
Total Accumulated Deficit	$	(807,604	)

The Fund has capital loss carryforwards that are identified in the Capital Loss Carryforward note that follows.

†

The difference between book-basis and tax-basis unrealized appreciation (depreciation) may be attributable to the losses deferred due to wash sale adjustments, foreign currency gains and losses, adjustments related to PFICs, REITs, RICs, certain derivatives and partnerships.

Total	$	1,080,774

During the year ended December 31, 2011, the Fund utilized $161,012 of prior year capital loss carryforwards.

Accounting for Uncertainty in Income Taxes – The Fund has adopted financial reporting rules that require the Fund to analyze all open tax years, as defined by the statute of limitations, for all major jurisdictions. Generally, tax authorities can examine all tax returns filed for the last three years. The Fund does not have an examination in progress.

The Fund has reviewed all open tax years and major jurisdictions and concluded that these financial reporting rules had no effect on the Fund’s financial position or results of operations. There is no tax liability resulting from unrecognized tax benefits relating to uncertain income tax positions taken or expected to be taken on the tax return for the fiscal year ended December 31, 2011. The Fund is also not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months.

Expenses:

Investment Management Agreement – HL Investment Advisors, LLC (“HL Advisors”), an indirect wholly owned subsidiary of The Hartford Financial Services Group, Inc. (“The Hartford”), serves as investment manager to the Fund pursuant to an Investment Management Agreement with the Company. As investment manager, HL Advisors has overall investment supervisory responsibility for the Fund. In addition, HL Advisors provides administrative personnel, services, equipment, facilities and office space for proper operation of the Fund. HL Advisors has contracted with Wellington Management Company, LLP (“Wellington Management”) under a sub-advisory agreement for the provision of day-to-day investment management services to the Fund in accordance with the Fund’s investment objective and policies. The Fund pays a fee to HL Advisors, a portion of which may be used to compensate Wellington Management.

Line of Credit:

The Fund is one of several Hartford funds that participate in a $500 million committed revolving line of credit facility. The facility is to be used for temporary or emergency purposes. Under the arrangement, the funds are required to own securities having a market value in excess of 300% of the total bank borrowings. The interest rate on borrowings varies depending on the nature of the loan. The facility also requires a fee to be paid based on the amount of the commitment. This commitment fee is allocated to all of the funds participating in the line of credit based on the average net assets of the funds. During the six-month period ended June 30, 2012, the Fund did not have any borrowings under this facility.
