Note 1 Business and Organization

Diamond Hill Investment Group, Inc. (the “Company”) derives its consolidated revenues and net income primarily from investment advisory and fund administration services. The Company has three operating subsidiaries.

Diamond Hill Capital Management, Inc. (“DHCM”), an Ohio corporation, is a wholly owned subsidiary of the Company and a registered investment adviser. DHCM is the investment adviser to the Diamond Hill Funds (the “Funds”), a series of open-end mutual funds and certain private investment funds (“Private Funds”), and also offers advisory services to institutional and individual investors.

Beacon Hill Fund Services, Inc. (“BHFS”), an Ohio corporation, is a wholly owned subsidiary of the Company. BHFS provides certain compliance, treasury, and other fund administration services to mutual fund companies. BHIL Distributors, Inc. (“BHIL”), an Ohio corporation, is a wholly owned subsidiary of BHFS. BHIL provides underwriting services to mutual funds. BHFS and BHIL collectively operate as Beacon Hill.

Note 2 Significant Accounting Policies

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses for the periods. Actual results could differ from those estimates. Certain prior period amounts and disclosures have been reclassified to conform to the current period financial presentation. Book value per share is computed by dividing total shareholders’ equity by the number of shares issued and outstanding at the end of the measurement period. The following is a summary of the Company’s significant accounting policies:

Principles of Consolidation

The accompanying consolidated financial statements include the operations of the Company and its subsidiaries. All material inter-company transactions and balances have been eliminated in consolidation.

Segment Information

Management has determined that the Company operates in one business segment, namely providing investment management and administration services to mutual funds, institutional accounts, and private investment funds. Therefore, no disclosures relating to operating segments are required in annual or interim financial statements.

Cash and Cash Equivalents

Cash and cash equivalents include demand deposits and money market mutual funds.

Accounts Receivable

Accounts receivable are recorded when they are due and are presented on the balance sheet net of any allowance for doubtful accounts. Accounts receivable are written off when they are determined to be uncollectible. Any allowance for doubtful accounts is estimated based on the Company’s historical losses, existing conditions in the industry, and the financial stability of those individuals or entities that owe the receivable. No allowance for doubtful accounts was deemed necessary at either March 31, 2013 or December 31, 2012.

Valuation of Investment Portfolio

Investments held by the Company are valued based upon the definition of Level 1 inputs and Level 2 inputs. Level 1 inputs are defined as fair values which use quoted prices in active markets for identical assets or liabilities. Level 2 inputs are defined as quoted prices in markets that are not considered to be active for identical assets or liabilities, quoted prices in active markets for similar assets or liabilities, and inputs other than quoted prices that are directly observable or indirectly through corroboration with observable market data. The following table summarizes the values of the Company’s investments based upon Level 1 and Level 2 inputs as of March 31, 2013 and December 31, 2012:

Level 1 investments are all registered investment companies (mutual funds) and include $2.0 million and $4.1 million, respectively, of money market mutual funds that the Company classifies as cash equivalents. Level 2 investments are all limited partnerships. There were no transfers in or out of the levels.

The changes in market values on the investments are recorded in the Consolidated Statements of Income as investment income.

Limited Partnership Interests

DHCM is the managing member of Diamond Hill General Partner, LLC (the “General Partner”), the general partner of Diamond Hill Investment Partners, L.P. (“DHIP”), Diamond Hill Research Partners – International, L.P. (“DHRPI”), and Diamond Hill Valuation-Weighted 500, L.P. (“DHVW”), formerly Diamond Hill Valuation-Based Index, L.P., collectively (the “Partnerships”), each a limited partnership whose underlying assets consist of marketable securities.

DHCM, in its role as managing member of the General Partner, has the power to direct each Partnership’s economic activities and the right to receive investment advisory and performance incentive fees that may be significant to the Partnerships. The Company evaluated these Partnerships to determine whether or not to consolidate the entities in accordance with FASB ASC 810, Consolidation. Certain of these Partnerships are considered to be variable interest entities (“VIEs”) while others are considered to be voting rights entities (“VREs”), both of which are subject to consolidation consideration. The Company would consolidate VIEs where the Company is considered the primary beneficiary or VREs where the General Partner is considered to control the Partnership. For the Partnerships that were considered VIEs, the Company was not deemed to be the primary beneficiary. For the Partnerships that were considered VREs, it was determined that the DHCM in its role of managing member of the General Partner did not control the Partnerships. Therefore, the investments are accounted for under the equity method rather than being consolidated in the accompanying financial statements.

Note 2 Significant Accounting Policies (Continued)

Limited Partnership Interests (Continued)

DHCM’s investments in these Partnerships are reported as a component of the Company’s investment portfolio, valued at DHCM’s proportionate interest in the net asset value of the marketable securities held by

the Partnerships. Gains and losses attributable to changes in the value of DHCM’s interests in the Partnerships are included in the Company’s reported investment income.

The Company’s exposure to loss as a result of its involvement with the Partnerships is limited to the amount of its investments. DHCM is not obligated to provide financial or other support to the Partnerships, other than its investments to date and its contractually provided investment advisory responsibilities, and has not provided such support. The Company has not provided liquidity arrangements, guarantees or other commitments to support the Partnerships’ operations, and the Partnerships’ creditors and interest holders have no recourse to the general credit of the Company.

Certain board members, officers and employees of the Company invest in DHIP. These individuals receive no remuneration as a result of their personal investment in the Partnership. The capital of the General Partner is not subject to a management fee or an incentive fee.

Furniture and Equipment

Furniture and equipment, consisting of computer equipment, furniture, and fixtures, are carried at cost less accumulated depreciation. Depreciation is calculated using the straight-line method over estimated lives of three to seven years.

Deferred Compensation Liability

Deferred compensation liability represents compensation that will be paid out upon satisfactory completion of certain performance-based criteria specified in employee award agreements issued pursuant to the 2011 Equity and Cash Incentive Plan. See Note 5.

Revenue Recognition – General

The Company earns substantially all of its revenue from investment advisory and fund administration services. Mutual fund investment advisory and administration fees, generally calculated as a percentage of assets under management (“AUM”), are recorded as revenue as services are performed. Managed account and private investment fund clients provide for monthly or quarterly management fees, in addition to periodic variable incentive fees.

Revenue Recognition – Incentive Revenue

The Company manages certain client accounts that provide for variable incentive fees. These fees are based on investment results over rolling five-year periods. For variable management fees based on a formula, there are two methods by which incentive revenue may be recorded. Under “Method 1”, incentive fees are recorded at the end of the contract measurement period; under “Method 2”, the incentive fees are recorded periodically and calculated as the amount that would be due under the formula at any point in time as if the contract was terminated at that date. Management has chosen Method 1, in which incentive fees are recorded at the end of the contract measurement period for the specific client which the incentive fee applies. The table below shows AUM subject to incentive fees and the incentive fees, as calculated under each of the above methods:

Revenue Recognition – Incentive Revenue (Continued)

Revenue Recognition – Mutual Fund Administration

DHCM has an administrative and transfer agency services agreement with the Funds, under which DHCM performs certain services for each fund. These services include mutual fund administration, transfer agency and other related functions. For performing these services, each fund pays DHCM a fee, which is calculated using the following annual rates times the average daily net assets of each respective fund and share class:

The Funds have selected and contractually engaged certain vendors to fulfill various services to benefit the Funds’ shareholders or to satisfy regulatory requirements of the Funds. These services include, among others, required fund shareholder mailings, federal and state registrations, and legal and audit services. DHCM, in fulfilling a portion of its role under the administration agreement with the Funds, acts as agent to pay these obligations of the Funds. Each vendor is independently responsible for fulfillment of the services it has been engaged to provide and negotiates fees and terms with the management and board of trustees of the Funds. The fee that each Fund pays to DHCM is reviewed annually by the Funds’ board of trustees and specifically takes into account the contractual expenses that DHCM pays on behalf of the Funds. As a result, DHCM is not involved in the delivery or pricing of these services and bears no risk related to these services. Revenue has been recorded net of these Fund related expenses, in accordance with FASB ASC 605-45, Revenue Recognition – Principal Agent Considerations. In addition, DHCM finances the upfront commissions which are paid to brokers who sell Class C shares of the Funds. As financer, DHCM advances the commission amount to be paid to the selling broker at the time of sale. These advances are capitalized and amortized over 12 months to correspond with the repayments DHCM receives from the principal underwriter to recoup this commission advancement.

Revenue Recognition – Mutual Fund Administration (Continued)

Beacon Hill has underwriting and administrative service agreements with certain clients, including registered mutual funds. The fee arrangements vary from client to client based upon services provided and are recorded as revenue under mutual fund administration on the Consolidated Statements of Income. Part of Beacon Hill’s role as underwriter is to act as an agent on behalf of its mutual fund clients to receive 12b-1/service fees and commission revenue and facilitate the payment of those fees and commissions to third parties who provide services to the funds and their shareholders. The amount of 12b-1/service fees and commissions are determined by each mutual fund client, and Beacon Hill bears no financial risk related to these services. As a result, 12b-1/service fees and commission revenue has been recorded net of the expense payments to third parties, in accordance with the appropriate accounting treatment for this agency relationship.

Mutual fund administration gross and net revenue are summarized below:

Third Party Distribution Expense

Third party distribution expenses are earned by various third party financial services firms based on sales and/or assets of the Company’s investment products generated by the respective firms. Expenses recognized represent actual payments made to the third party firms and are recorded in the period earned based on the terms of the various contracts.

Note 2 Significant Accounting Policies (Continued)

Income Taxes

The Company accounts for income taxes through an asset and liability approach. Deferred taxes are provided on an asset and liability method, whereby deferred tax assets are recognized for deductible temporary differences and deferred tax liabilities are recognized for taxable temporary differences. Deferred tax assets are reduced by a valuation allowance when it is more likely than not that some portion or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment.

The Company is subject to examination by various federal, state and local jurisdictions for various tax periods. The Company’s income tax positions are based on research and interpretations of the income tax laws and rulings in each of the jurisdictions in which the Company does business. Due to the subjectivity of interpretations of laws and rulings in each jurisdiction, the differences and interplay in tax laws between those jurisdictions, as well as the inherent uncertainty in estimating the final resolution of complex tax audit matters, the Company’s estimates of income tax liabilities may differ from actual payments or assessments. The Company regularly assesses its position with regard to tax exposures and records liabilities for these uncertain tax positions and related interest and penalties, if any, according to the principles of FASB ASC 740, Income Taxes. As of March 31, 2013, the Company has not recorded any liability for uncertain tax positions.

Earnings Per Share

Earnings per share (“EPS”) is computed by dividing net income by the weighted average number of common shares outstanding for the period. For the periods presented, the Company has unvested stock-based payment awards that contain nonforfeitable rights to dividends. For the periods presented, the Company does not have dilutive securities outstanding.

Note 3 Investment Portfolio

As of March 31, 2013, the Company held investments (excluding money market funds, which are included with cash and cash equivalents) worth $18.4 million and an estimated cost basis of $12.4 million. The following table summarizes the market value of these investments:

Note 3 Investment Portfolio (Continued)

DHCM is the managing member of Diamond Hill General Partner LLC, which is the general partner of the Partnerships. The underlying assets of the Partnerships are cash and marketable equity securities. Summary financial information, including the Company’s carrying value and income from the Partnerships, is as follows:

Note 4 Capital Stock

Common Shares

The Company has only one class of securities outstanding, Common Shares, no par value per share.

Authorization of Preferred Shares

The Company’s Amended and Restated Articles of Incorporation authorize the issuance of 1,000,000 shares of “blank check” preferred shares with such designations, rights and preferences, as may be determined from time to time by the Company’s Board of Directors. The Board of Directors is authorized, without shareholder approval, to issue preferred stock with dividend, liquidation, conversion, voting, or other rights, which could adversely affect the voting or other rights of the holders of the Common Shares. There were no preferred shares issued or outstanding at either March 31, 2013 or December 31, 2012.

Note 5 Stock-Based Compensation

Equity Incentive Plans

2011 Equity and Cash Incentive Plan

At the Company’s annual shareholder meeting on April 26, 2011, shareholders approved the 2011 Equity and Cash Incentive Plan (“2011 Plan”). The 2011 Plan is intended to facilitate the Company’s ability to attract and retain staff, provide additional incentives to employees, directors and consultants, and promote the success of the Company’s business. The 2011 Plan authorizes the issuance of 600,000 Common Shares of the Company in various forms of equity awards. The 2011 Plan also authorizes cash incentive awards. As of March 31, 2013, there were 244,570 Common Shares available for awards under the 2011 Plan. The 2011 Plan provides that the Board of Directors, or a committee appointed by the Board, may grant awards and otherwise administer the 2011 Plan. Restricted stock grants issued under the 2011 Plan, which vest over time, are recorded as deferred compensation in the equity section of the balance sheet on the grant date and then recognized as compensation expense based on the grant date price over the vesting period of the respective grant.

Note 5 Stock-Based Compensation (Continued)

2005 Employee and Director Equity Incentive Plan

At the Company’s annual shareholder meeting on May 12, 2005, shareholders approved the 2005 Employee and Director Equity Incentive Plan (“2005 Plan”). There are no longer any Common Shares available for future issuance under the 2005 Plan, although outstanding grants under the 2005 Plan remain issued and outstanding. Restricted stock grants issued under the 2005 Plan, which vest over time, are recorded as deferred compensation in the equity section of the balance sheet on the grant date and then recognized as compensation expense based on the grant date price over the vesting period of the respective grant.

Restricted Stock Grant Transactions

The following table represents a roll-forward of outstanding restricted stock grants issued pursuant to the 2011 and 2005 Plans and related activity during the year ended December 31, 2012 and the three months ended March 31, 2013:

The total outstanding restricted stock grants shown above are included in issued and outstanding shares. Total deferred compensation related to unvested restricted stock grants was $14,388,976 as of March 31, 2013. Expense recognition of deferred compensation over the remaining vesting periods is as follows:

401(k) Plan

The Company sponsors a 401(k) plan in which all employees participate. Employees may contribute a portion of their compensation subject to certain limits based on federal tax laws. The Company makes matching contributions of Common Shares of the Company with a value equal to 200 percent of the first six percent of an employee’s compensation contributed to the plan. Employees become fully vested in the matching contributions after six plan years of employment. The following table summarizes the Company’s expenses attributable to the plan during the three months ended March 31, 2013 and 2012:

Note 6 Operating Leases

The Company leases approximately 25,500 square feet of office space at two locations. The following table summarizes the total lease and operating expenses for the three months ended March 31, 2013 and 2012:

The approximate future minimum lease payments under the operating leases are as follows:

In addition to the above rent, the Company is also responsible for normal operating expenses of the properties. Such operating expenses were approximately $9.69 per square foot in 2012, on a combined basis, and are expected to be approximately $9.80 per square foot in 2013.

Note 7 Income Taxes

The provision for income taxes for the three months ended March 31, 2013 and 2012 consists of federal, state and city income taxes. The effective tax rates for the three months ended March 31, 2013 and 2012 were 36.9% and 36.8%, respectively. During 2012, the Company determined it was entitled to a tax deduction related to dividends paid on unvested restricted stock. The resulting tax benefit of $1.9 million was recorded as a reduction of income taxes payable and an increase in shareholders’ equity.

The net temporary differences incurred to date will reverse in future periods as the Company generates taxable earnings. The Company believes it is more likely than not that the results of future operations will generate sufficient taxable income to realize the net deferred tax assets recorded. The Company records a valuation when it is more likely than not that some portion of all of the deferred tax assets will not be realized. As of March 31, 2013 and December 31, 2012, no valuation allowance was deemed necessary.

FASB ASC 740, Income Taxes, prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return and also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company did not record an accrual for tax related uncertainties or unrecognized tax positions as of March 31, 2013 and December 31, 2012. The Company does not expect a change to the reserve for uncertain tax positions within the next twelve months that would have a material impact on the consolidation financial statements.

The Company files income tax returns in the federal and all applicable state and local jurisdictions. The Company is subject to federal, state and local examinations by tax authorities for tax years ended December 31, 2009 through 2012.

Note 8 Earnings Per Share

The following table sets forth the computation for EPS:

For the periods presented, the Company has unvested stock-based payment awards that contain nonforfeitable rights to dividends and are included in the computation of basic EPS above as participating shares. For the periods presented, the Company does not have dilutive securities outstanding.

Note 9 Regulatory Requirements

BHIL, a wholly owned subsidiary of the Company and principal underwriter for mutual funds, is subject to the U.S. Securities and Exchange Commission (“SEC”) uniform net capital rule, which requires the maintenance of minimum net capital. BHIL’s net capital exceeded its minimum net capital requirement at March 31, 2013 and December 31, 2012. The net capital balances, minimum net capital requirements, and ratios of aggregate indebtedness to net capital for BHIL are summarized below as of March 31, 2013 and December 31, 2012:

Note 10 Commitments and Contingencies

The Company indemnifies its directors and certain of its officers and employees for certain liabilities that might arise from their performance of their duties to the Company. Additionally, in the normal course of business, the Company enters into agreements that contain a variety of representations and warranties and which provide general indemnifications. Certain agreements do not contain any limits on the Company’s liability and would involve future claims that may be made against the Company that have not yet occurred. Therefore, it is not possible to estimate the Company’s potential liability under these indemnities. Further, the Company maintains insurance policies that may provide coverage against certain claims under these indemnities.

Note 11 Subsequent Event

On April 10, 2013 a client notified the Company that in connection with a recently announced acquisition, it would be replacing DHCM and another unaffiliated adviser, as the sub-advisers on two accounts in June 2013. The revenue generated from two accounts currently represents approximately 2.6% of the Company’s annualized revenue.

Forward-looking Statements

Throughout this Quarterly Report on Form 10-Q, Diamond Hill Investment Group, Inc. may make forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), relating to such matters as anticipated operating results, prospects for achieving the critical threshold of assets under management, technological developments, economic trends (including interest rates and market volatility), expected transactions and acquisitions and similar matters. The words “believe,” “expect,” “anticipate,” “estimate,” “should,” “hope,” “seek,” “plan,” “intend” and similar expressions identify forward-looking statements that speak only as of the date thereof. While the Company believes that the assumptions underlying its forward-looking statements are reasonable, investors are cautioned that any of the assumptions could prove to be inaccurate and accordingly, the actual results and experiences of the Company could differ materially from the anticipated results or other expectations expressed by the Company in its forward-looking statements. Factors that could cause such actual results or experiences to differ from results discussed in the forward-looking statements include, but are not limited to: the adverse effect from a decline in the securities markets; a decline in the performance of the Company’s products; changes in interest rates; changes in national and local economic and political conditions, including the effects of implementation of the Budget Control Act of 2011 and the American Taxpayer Relief Act of 2012 and the continuing economic uncertainty in various parts of the world; changes in government policy and regulation, including monetary policy; changes in the Company’s ability to attract or retain key employees; unforeseen costs and other effects related to legal proceedings or investigations of governmental and self-regulatory organizations; and other risks identified from time-to-time in the Company’s other public documents on file with the U. S. Securities and Exchange Commission (“SEC”), including those discussed below in Item 1A of Part II. When we use the terms the “Company,” “management,” “we,” “us,” and “our,” we mean Diamond Hill Investment Group, Inc. and its subsidiaries.

General

The Company, an Ohio corporation organized in April 1990, derives its consolidated revenue and net income from investment advisory and fund administration services provided by its subsidiaries DHCM, BHFS, and BHIL. BHFS and BHIL collectively operate as Beacon Hill. DHCM is a registered investment adviser under the Investment Advisers Act of 1940. DHCM sponsors, distributes, and provides investment advisory and related services to various U.S. and foreign clients through the Funds, institutional accounts, and private investment funds (generally known as “hedge funds”). Beacon Hill provides fund administration and statutory underwriting services to various clients, including the Funds.

The Company’s primary objective is to fulfill its fiduciary duty to clients. Its secondary objective is to grow the intrinsic value of the Company in order to achieve an adequate long-term return for shareholders.

In this section, the Company discusses and analyzes the consolidated results of operations for the three month periods ended March 31, 2013 and 2012 and other factors that may affect future financial performance. The accompanying unaudited consolidated financial statements were prepared in accordance with the instructions for Form 10-Q and, therefore, do not include information or footnotes necessary for a complete presentation of financial position, results of operations and cash flows in conformity with United States generally accepted accounting principles. Accordingly, these financial statements should be read in conjunction with the Consolidated Financial Statements and Notes thereto of the Company included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. However, in the opinion of management, all adjustments (consisting of only normal recurring accruals) which are necessary for a fair presentation of the financial statements have been included. The results of operations for the three month period ended March 31, 2013 are not necessarily indicative of the results which may be expected for the entire fiscal year.

Assets Under Management

The Company’s revenue is derived primarily from investment advisory and administration fees. Investment advisory and administration fees paid to the Company are generally based on the value of the investment portfolios managed by the Company and fluctuate with changes in the total value of the AUM. Such fees are recognized in the period that the Company manages these assets. The Company’s primary expense is employee compensation and benefits.

Revenues are highly dependent on both the value and composition of AUM. The following is a summary of the Company’s AUM by product, investment objective, and a roll-forward of the change in AUM for the three months ended March 31, 2013 and 2012:

Consolidated Results of Operations

The following is a discussion of the consolidated results of operations of the Company.

Three Months Ended March 31, 2013 compared with Three Months Ended March 31, 2012

The Company generated net income of $5.3 million ($1.67 per share) for the three months ended March 31, 2013, compared with net income of $4.6 million ($1.52 per share) for the three months ended March 31, 2012. Operating income increased by $607 thousand period over period primarily due to an increase in AUM, resulting in a $1.7 million increase in revenue. The revenue increase was offset by an increase in operating expenses of $1.1 million, primarily related to an increase in compensation and related expenses. The Company’s corporate investments also contributed to the overall increase in net income. Operating profit margin remained flat at 36% for the first quarter 2013 and 2012. The Company expects that its operating margin will fluctuate from year to year based on various factors including revenues; investment results; employee performance; staffing levels; development of investment strategies, products, or channels; and industry comparisons.

Revenue

As a percent of total first quarter 2013 revenues, investment advisory fees accounted for 86% and mutual fund administration fees made up the remaining 14%. This compared to 87% and 13%, respectively, for first quarter 2012.

Investment Advisory Fees. Investment advisory fees increased by $1.5 million, or 10%, from the quarter ended March 31, 2012 to the quarter ended March 31, 2013. Investment advisory fees are calculated as a percentage of average net AUM at various rates depending on the investment product. The primary contributor to the increase in investment advisory fees is an increase of 12% in average AUM quarter over quarter, offset by a decline of one basis point in the average advisory fee rate from 0.64% for the quarter ended March 31, 2012 to 0.63% for the quarter ended March 31, 2013.

Mutual Fund Administration Fees. Mutual fund administration fees increased $263 thousand, or 12%, from the quarter ended March 31, 2012 to the quarter ended March 31, 2013. Mutual fund administration fees include administration fees received from the Funds, which are calculated as a percentage of average mutual fund AUM, and all Beacon Hill fee revenue. The increase in the mutual fund administration fee is due to a 25% increase in average mutual fund AUM from $4.5 billion for the quarter ended March 31, 2012 to $5.6 billion for the quarter ended March 31, 2013 offset by a decline of one basis point in the net administration fee rate from 0.17% for the quarter ended March 31, 2012 to 0.16% for the quarter ended March 31, 2013.

Expenses

Compensation and Related Costs. Employee compensation and benefits increased by $1.0 million, or 12%, during the quarter ended March 31, 2013 compared to the quarter ended March 31, 2012, primarily due to an increase of $629 thousand in incentive compensation and an increase of $413 thousand in salaries and related benefits due to an increase in staffing levels.

General and Administrative. General and administrative expenses increased by $142 thousand, or 13%, period over period. This increase is primarily due to additional research expenses to support the Company’s investment team, corporate legal expenses, and consulting fees.

Sales and Marketing. Sales and marketing expenses increased by $71 thousand, or 23%. This increase was primarily due to an overall increase in travel and other expenses related to business development and retention efforts during first quarter 2013.

Third Party Distribution. Third party distribution expense represents payments made to intermediaries related to sales of the Company’s investment products. This expense is directly correlated with investments in the Company’s proprietary funds. The period-over-period change directly corresponds to the change in investment advisory fees earned by the Company related to those products.

Mutual Fund Administration. Mutual fund administration expenses decreased by $38 thousand, or 9%, period over period. The majority of mutual fund administration fees are variable based upon the amount of mutual fund AUM or the number of shareholder accounts. While average mutual fund AUM increased by 25% from March 31, 2012 to March 31, 2013, the number of direct shareholder accounts decreased by 34% related to a continuing shift in the servicing of shareholder accounts from the fund’s transfer agent to omnibus shareholder accounting at third party intermediaries. The costs associated with servicing these shareholder accounts are now reflected as Fund Related Expenses (see Note 2: Revenue Recognition – Mutual Fund Administration).

Liquidity and Capital Resources

Sources of Liquidity

The Company’s main source of liquidity is cash flow from operating activities which is generated from investment advisory and fund administration fees. The Company’s entire investment portfolio is in readily marketable securities, which provide for cash liquidity, if needed. Investments in mutual funds are valued at their quoted current net asset value. Investments in private investment funds are valued independently based on readily available market quotations. Inflation is expected to have no material impact on the Company’s performance. Cash and cash equivalents, accounts receivables, and investments represent approximately 86% and 84% of total assets as of March 31, 2013 and December 31, 2012 respectively. The Company believes these sources of liquidity as well as continuing cash flows from operating activities will be sufficient to meet current and future operating needs for at least the next 12 months.

Uses of Liquidity

In line with the Company’s primary objective to fulfill its fiduciary duty to clients and secondary objective to achieve an adequate long-term return for shareholders, the Company anticipates the main uses of cash will be operating expenses.

The Board of Directors and management continually review various factors to determine whether the Company has capital in excess of that required for the business and the appropriate use of any excess capital. The factors considered include the Company’s investment opportunities, the Company’s risks, and future dividend and capital gain tax rates. Evaluating management’s stewardship of capital for shareholders is a central part of our investment discipline that we practice for our clients. We hold ourselves to the same standard that we look for when evaluating investments for our clients.

Working Capital

As of March 31, 2013, the Company had working capital of approximately $28.9 million compared to $17.6 million at December 31, 2012. Working capital includes cash, securities owned and current receivables, net of all liabilities. On December 5, 2012, the Company’s Board of Directors declared an $8.00 per share dividend payable on December 21, 2012 to shareholders of record on December 17, 2012. The payment of the special cash dividend reduced the Company’s working capital balance. The Company has no debt, and believes its available working capital is sufficient to cover current expenses. The Company does not expect any material capital expenditures during 2013.

Cash Flow Analysis

Cash Flows from Operating Activities

The Company’s cash flows from operating activities are calculated by adjusting net income to reflect other significant operating sources and uses of cash, certain significant non-cash items such as share-based compensation, and timing differences in the cash settlement of operating assets and liabilities.

As of March 31, 2013 and 2012, net cash used in operating activities totaled $2.2 million and $2.8 million, respectively. The changes in net cash provided by operating activities generally reflect net income plus the effect of non-cash items and the timing differences in the cash settlement of assets and liabilities.

Cash Flows from Investing Activities

The Company’s cash flows from investing activities consist primarily of capital expenditures and the purchase and redemption of the Company’s investment portfolio.

Cash flows used in investing activities totaled $305 thousand for the quarter ended March 31, 2013 related to the purchase of furniture and fixtures. Cash flows used in investing activities totaled $2.4 million for the quarter ended March 31, 2012 primarily due to purchases into the Company’s corporate investments.

Cash Flows from Financing Activities

The Company’s cash flows from financing activities consist primarily of the payment of special dividends, the repurchase of Common Shares, and the payment of taxes withheld on employee stock transactions offset by the proceeds from the issuance of Common Shares.

As of March 31, 2013, there were no cash flows in financing activities. As of March 31, 2012, net cash used by financing activities totaled $354 thousand primarily related to the payment of taxes withheld on employee stock transactions.

Use of Supplemental Data as Non-GAAP Performance Measure

Net Operating Income After Tax

As supplemental information, we are providing performance measures that are based on methodologies other than generally accepted accounting principles (“non-GAAP”) for “Net Operating Income After Tax” that management uses as benchmarks in evaluating and comparing the period-to-period operating performance of the Company and its subsidiaries.

The Company defines “net operating income after tax” as the Company’s net operating income less income tax provision excluding investment income and the tax impact related to the investment income. The Company believes that “net operating income after tax” provides a good representation of the Company’s operating performance, as it excludes the impact of investment income on financial results. The amount of the investment portfolio and market fluctuations on the investments can change significantly from one period to another, which can distort the underlying earnings potential of a company. We also believe “net operating income after tax” is an important metric in estimating the value of an asset management business. This non-GAAP measure is provided in addition to net income and net operating income and is not a substitute for net income or net operating income and may not be comparable to non-GAAP performance measures of other companies.

The tax provision excluding impact of investment income is calculated by applying the tax rate calculated from the income statement to net operating income.

Off-Balance Sheet Arrangements

The Company has no off-balance sheet arrangements. It does not have any obligation under a guarantee contract, or a retained or contingent interest in assets or similar arrangement that serves as credit, liquidity or market risk support for such assets, or any other obligation, including a contingent obligation, under a contract that would be accounted for as a derivative instrument or arising out of a variable interest.
