NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

March 31, 2017

(Unaudited)

A.  Significant Accounting Policies

Basis of Presentation

Unless we have indicated otherwise, or the context otherwise requires, references in this report to “GAMCO Investors, Inc.,” “GAMCO,” “the Company,” “GBL,” “we,” “us” and “our” or similar terms are to GAMCO Investors, Inc., its predecessors and its subsidiaries.

The unaudited interim condensed consolidated financial statements of GAMCO included herein have been prepared in conformity with generally accepted accounting principles (“GAAP”) in the United States for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by U.S. GAAP in the United States for complete financial statements.  In the opinion of management, the unaudited interim condensed consolidated financial statements reflect all adjustments, which are of a normal recurring nature, necessary for a fair presentation of financial position, results of operations and cash flows of GAMCO for the interim periods presented and are not necessarily indicative of a full year’s results.

The interim condensed consolidated financial statements include the accounts of GAMCO and its subsidiaries.  Intercompany accounts and transactions are eliminated.

These interim condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2016.

Use of Estimates

The preparation of the interim condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported on the interim condensed consolidated financial statements and accompanying notes.  Actual results could differ from those estimates.

Recent Accounting Developments

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, "Revenue from Contracts with Customers," which supersedes the revenue recognition requirements in the Accounting Standards Codification ("Codification") Topic 605, Revenue Recognition, and most industry-specific guidance throughout the industry topics of the Codification.  The core principle of the new ASU No. 2014-09 is for companies to recognize revenue from the transfer of goods or services to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services.  The new standard provides a five-step approach to be applied to all contracts with customers and also requires expanded disclosures about revenue recognition.  The ASU is effective for annual reporting periods beginning after December 15, 2017, including interim periods and is to be retrospectively applied.  Early adoption is not permitted.  The Company is currently evaluating this guidance and the impact it will have on its consolidated financial statements.

In January 2016, the FASB issued ASU 2016-01, which amends the guidance in U.S. GAAP on the classification and measurement of financial instruments. Although the ASU retains many current requirements, it significantly revises an entity’s accounting related to (1) the classification and measurement of investments in equity securities and (2) the presentation of certain fair value changes for financial liabilities measured at fair value. The ASU also amends certain disclosure requirements associated with the fair value of financial instruments. For public companies, the new standard is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2017. To adopt the amendments, entities will be required to make a cumulative-effect adjustment to beginning retained earnings as of the beginning of the fiscal year in which the guidance is effective. The Company is currently evaluating this guidance and the impact it will have on its consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, which amends the guidance in U.S. GAAP for the accounting for leases.  ASU 2016-02 requires a lessee to recognize assets and liabilities arising from most operating leases in the condensed consolidated statement of financial position.  ASU 2016-02 is effective beginning January 1, 2019. The Company is currently evaluating this guidance and the impact it will have on its consolidated financial statements.

10

In March 2016, the FASB issued ASU 2016-09, which simplifies several aspects of the accounting for employee share-based payment transactions for both public and nonpublic entities, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. For public companies, the ASU is effective for annual reporting periods beginning after December 15, 2016, including interim periods within those annual reporting periods.  The Company adopted this guidance on January 1, 2017 without a material impact to the consolidated financial statements.

In August 2016, the FASB issued ASU 2016-15, which adds and clarifies guidance on the classification of certain cash receipts and payments in the consolidated statements of cash flows.  For public companies, the ASU is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those annual reporting periods.  Early adoption is permitted. The Company is currently evaluating this guidance and the impact it will have on its consolidated financial statements.

In January 2017, the FASB issued ASU 2017-04 to simplify the process used to test for goodwill.  Under the new standard, if “the carrying amount of a reporting unit exceeds its fair value, an impairment loss shall be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit.”  For public companies, the ASU is effective for annual and any interim impairment tests for periods beginning after December 15, 2019.  Early adoption is permitted for impairment tests that occur after January 1, 2017. The Company is currently evaluating this guidance and the impact it will have on its condensed consolidated financial statements.

B.  Investment in Securities

Investments in securities at March 31, 2017, December 31, 2016 and March 31, 2016 consisted of the following:

Total investments in securities	$	18,858	$	33,190	$	18,889	$	37,285	$	17,607	$	36,419

There were no securities sold, not yet purchased at March 31, 2017, December 31, 2016 and March 31, 2016.

Management determines the appropriate classification of debt and equity securities at the time of purchase and reevaluates such designation as of the date of each condensed consolidated statement of financial condition.  Investments in United States Treasury Bills and Notes with maturities of greater than three months at the time of purchase are classified as investments in securities, and those with maturities of three months or less at the time of purchase are classified as cash equivalents.  The portion of investments in securities held for resale in anticipation of short-term market movements are classified as trading securities.  Trading securities are stated at fair value, with any unrealized gains or losses reported in current period earnings.  Available for sale (“AFS”) investments are stated at fair value, with any unrealized gains or losses, net of taxes, reported as a component of equity except for losses deemed to be other than temporary (“OTT”) which are recorded as realized losses in the condensed consolidated statements of income.

The following table identifies all reclassifications out of accumulated other comprehensive income ("AOCI") into income for the three months ended March 31, 2017 and 2016 (in thousands):

Amount					Affected Line Items	Reason for

The following is a summary of the cost, gross unrealized gains, gross unrealized losses and fair value of available for sale investments as of March 31, 2017, December 31, 2016 and March 31, 2016:

Total available for sale securities	$	17,592	$	18,810	$	-	$	36,402

A net unrealized loss, net of taxes, for the three months ended March 31, 2017 of $2.6 million has been included in other comprehensive income, a component of equity, at March 31, 2017.  A net unrealized gain, net of taxes, for the three months ended March 31, 2016 of $2.6 million has been included in other comprehensive income, a component of equity, at March 31, 2016.  There were no sales of investments available for sale for the three months ended March 31, 2017. During the three months ended March 31, 2016, proceeds from the sales of investments available for sale were approximately $308,000 and gross gains on the sale of investments available for sale amounted to $2,000 and were reclassified from other comprehensive income into net gain from investments in the condensed consolidated statements of income. There were no realized losses on the sale of investments available for sale for the three months ended March 31, 2017 or March 31, 2016. The basis on which the cost of a security sold is determined using specific identification. Accumulated other comprehensive income on the consolidated statements of equity is primarily comprised of unrealized gains/losses, net of taxes, for AFS securities.

GBL has an established accounting policy and methodology to determine other-than-temporary impairment on available for sale securities.  Under this policy, available for sale securities are evaluated for other than temporary impairments and any impairment charges are recorded in net gain/(loss) from investments on the condensed consolidated statements of income. Management reviews all available for sale securities whose cost exceeds their market value to determine if the impairment is other than temporary.  Management uses qualitative factors such as diversification of the investment, the amount of time that the investment has been impaired, the intent to sell and the severity of the decline in determining whether the impairment is other than temporary.

There were no investments classified as available for sale that were in an unrealized loss position at March 31, 2017, December 31, 2016 or March 31, 2016.

For the three months ended March 31, 2017 and 2016 there were no losses on available for sale securities that were deemed to be other than temporary.

C. Fair Value

The following tables present information about the Company's assets and liabilities by major categories measured at fair value on a recurring basis as of March 31, 2017, December 31, 2016 and March 31, 2016 and indicates the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair value:

D. Income Taxes

The effective tax rate ("ETR") for the three months ended March 31, 2017 and March 31, 2016 was 38.1% and 38.2%, respectively.

ASU 2016-09, which was issued in March 2016 and became effective for interim and annual reporting periods beginning after December 15, 2016, simplifies several aspects of accounting for employee share-based payment transactions. Upon adoption of ASU 2016-09 on January 1, 2017, our accounting for excess tax benefits has changed and adopted prospectively, resulting in recognition of excess tax benefits against income tax expenses rather than additional paid-in capital.

E. Earnings Per Share

4.5% Convertible Note

On August 15, 2016, the Company issued and sold a 5-year, $110 million convertible note (“Convertible Note”).  The note bears interest at a rate of 4.5% per annum and is convertible into shares of the Company’s Class A Common stock (“Class A Stock”) at an initial conversion price of $55.00 per share.  The Convertible Note is initially convertible into two million shares of the Company’s Class A Stock, subject to adjustment pursuant to the terms of the Convertible Note.  The Company is required to repurchase the Convertible Note at the request of the holder on specified dates or after certain circumstances involving a Fundamental Change (as defined in the Convertible Note).  The Company recorded $174,000 of costs in connection with the issuance of the Convertible Note.  GGCP, Inc. (“GGCP”), which owns approximately 63% of the equity interest of the Company, has deposited cash equal to the principal amount of the Note and six months interest (“Initial Deposit”) into an escrow account established pursuant to an escrow agreement by and among GGCP, the Company, the Convertible Note holder and the escrow agent.  In connection with the Initial Deposit made by GGCP, the Company has agreed that GGCP has a right to demand payment in an amount equal to any funds withdrawn from the escrow account by the Convertible Note holder.

14

AC 4% PIK Note

In connection with the Spin-off of AC on November 30, 2015, the Company issued a $250 million promissory note (the “AC 4% PIK Note”) payable to AC. The AC 4% PIK Note bears interest at 4.0% per annum.  The original principal amount has a maturity date of November 30, 2020.  Interest on the AC 4% PIK Note will accrue from the date of the last interest payment, or if no interest has been paid, from the effective date of the AC 4% PIK Note.  At the election of the Company, payment of interest on the AC 4% PIK Note may be paid in kind (in whole or in part) on the then-outstanding principal amount (a “PIK Amount”) in lieu of cash. All PIK Amounts added to the outstanding principal amount of the AC 4% PIK Note will mature on the fifth anniversary from the date the PIK Amount was added to the outstanding principal of the AC 4% PIK Note. In no event may any interest be paid in kind subsequent to November 30, 2019. The Company may prepay the AC 4% PIK Note (in whole or in part) prior to maturity without penalty.

During the three months ended March 31, 2017, the Company prepaid $10 million of principal of the AC 4% PIK Note against the principal amount due on November 30, 2017.  Of the $90 million principal amount outstanding at March 31, 2017, $20 million is due on November 30, 2018, $20 million is due on November 30, 2019, and $50 million is due on November 30, 2020.

5.875% Senior notes

On May 31, 2011, the Company issued 10-year, $100 million senior notes ("Senior Notes").  The Senior Notes mature on June 1, 2021 and bear interest at 5.875% per annum, payable semi-annually on June 1 and December 1 of each year and commenced on December 1, 2011.  Upon the occurrence of a change of control triggering event, as defined in the indenture, the Company would be required to offer to repurchase the Senior Notes at 101% of their principal amount.

At March 31, 2017, December 31, 2016 and March 31, 2016, the debt was recorded at its face value, net of issuance costs, of $24.1 million, $24.1 million and $24.1 million, respectively.

Loan from GGCP

In connection with the Offer, the Company borrowed $35.0 million from GGCP. The loan had a term of one year and bore interest at 90-day LIBOR plus 3.25%, reset and payable quarterly. On March 18, 2016, the Company paid back $15.0 million of the loan.  During the second quarter of 2016 the Company paid back the remaining $20.0 million of the loan.  At March 31, 2016, the debt was recorded at its face value of $20.0 million.

The fair value of the Company's debt, which is a Level 2 valuation, is estimated based on either quoted market prices for the same or similar issues or on the current rates offered to the Company for debt of the same remaining maturities or using market standard models.  Inputs in these standard models include credit rating, maturity and interest rate.

G. Stockholders' Equity

Shares outstanding were 29.3 million, 29.5 million and 29.8 million on March 31, 2017, December 31, 2016 and March 31, 2016, respectively.

Voting Rights

The holders of Class A Stock and Class B Common stock ("Class B Stock") have identical rights except that (i) holders of Class A Stock are entitled to one vote per share, while holders of Class B Stock are entitled to ten votes per share on all matters to be voted on by shareholders in general, and (ii) holders of Class A Stock are not eligible to vote on matters relating exclusively to Class B Stock and vice versa.

Stock Award and Incentive Plan

The Company maintains two Plans approved by the shareholders, which are designed to provide incentives which will attract and retain individuals key to the success of GBL through direct or indirect ownership of our common stock. Benefits under the Plans may be granted in any one or a combination of stock options, stock appreciation rights, restricted stock, restricted stock units, stock awards, dividend equivalents and other stock or cash based awards. A maximum of 4.0 million shares of Class A Stock have been reserved for issuance under the Plans by a committee of the Board of Directors responsible for administering the Plans ("Compensation Committee"). Under the Plans, the committee may grant RSAs and either incentive or nonqualified stock options with a term not to exceed ten years from the grant date and at an exercise price that the committee may determine.

As of March 31, 2017, December 31, 2016 and March 31, 2016, there were 420,240 RSA shares, 424,340 RSA shares and 553,100 RSA shares outstanding, respectively, that were previously issued at an average weighted grant price of $65.59, $65.74 and $64.02, respectively. These RSA grants occurred prior to the spin-off of Associated Capital. On November 30, 2015, pursuant to the spin-off, all RSA grant holders received shares of Associated Capital’s Class A common stock as a result of their ownership of their GAMCO unvested RSAs (one share of Associated Capital for each share of GBL). All grants of the RSA shares were recommended by the Company's Chairman, who did not receive a RSA, and approved by the Compensation Committee. This expense, net of estimated forfeitures, is recognized over the vesting period for these awards which is either (1) 30% over three years from the date of grant and 70% over five years from the date of grant or (2) 30% over three years from the date of grant and 10% each year over years four through ten from the date of grant.  During the vesting period, dividends to RSA holders are held for them until the RSA vesting dates and are forfeited if the grantee is no longer employed by the Company on the vesting dates.  Dividends declared on these RSAs, less estimated forfeitures, are charged to retained earnings (deficit) on the declaration date.

ASU 2016-09, which was issued in March 2016 and became effective for interim and annual reporting periods beginning after December 15, 2016, simplifies several aspects of accounting for employee share-based payment transactions. Upon adoption of ASU 2016-09 on January 1, 2017, the Company elected not to change its accounting policy on forfeitures and continue to estimate forfeitures rather than accounting for forfeitures as they occur, an alternative allowed under ASU 2016-09.

For the three months ended March 31, 2017 and March 31, 2016, we recognized stock-based compensation expense of $0.7 million and $1.0 million, respectively. Actual and projected stock-based compensation expense for RSA shares for the years ended December 31, 2016 through December 31, 2024 (based on awards currently issued or granted) is as follows (in thousands):

		2016		2017		2018		2019		2020

The total compensation cost related to non-vested RSAs not yet recognized is approximately $6.7 million as of March 31, 2017.

Stock Repurchase Program

In March 1999, GAMCO's Board of Directors established the Stock Repurchase Program to grant management the authority to repurchase shares of our Class A Common Stock.  For the three months ended March 31, 2017 and March 31, 2016, the Company repurchased 125,410 shares and 30,503 shares, respectively, at an average price per share of $30.25 and $29.42, respectively. From the inception of the program through March 31, 2017, 10,026,750 shares have been repurchased at an average price of $44.14 per share.  At March 31, 2017, the total shares available under the program to be repurchased in the future were 108,058.

16

Shelf Registration

On May 4, 2015, the Securities and Exchange Commission (“SEC”) declared effective the “shelf” registration statement filed by the Company. The “shelf” provides the Company with the flexibility of issuing any combination of senior and subordinated debt securities, convertible securities and common and preferred securities up to a total amount of $500 million and replaced the existing shelf registration which expired in May 2015.  As of March 31, 2017, $500 million is available on the shelf.

H. Identifiable Intangible Assets

As a result of becoming the advisor to the Gabelli Enterprise Mergers and Acquisitions Fund and the associated consideration paid, the Company maintains an identifiable intangible asset of $1.9 million within other assets on the condensed consolidated statements of financial condition at March 31, 2017, December 31, 2016 and March 31, 2016. The investment advisory agreement is subject to annual renewal by the fund's Board of Directors, which the Company expects to be renewed, and the Company does not expect to incur additional expense as a result, which is consistent with other investment advisory agreements entered into by the Company.  The advisory contract is next up for renewal in February 2018. On November 1, 2015, as a result of becoming the advisor to the Bancroft Fund Ltd. and the Ellsworth Growth and Income Fund Ltd. and the associated consideration paid, the Company maintains an identifiable intangible asset of $1.6 million within other assets on the condensed consolidated statement of financial condition at March 31, 2017, December 31, 2016 and March 31, 2016.  The advisory contracts for the Bancroft Fund Ltd. and the Ellsworth Growth and Income Fund Ltd. are both next up for renewal in August 2017. The Company assesses the recoverability of this intangible asset at least annually, or more often should events warrant. There were no indicators of impairment for the three months ended March 31, 2017 or March 31, 2016, and as such there was no impairment analysis performed or charge recorded.

I. Commitments and Contingencies

From time to time, the Company may be named in legal actions and proceedings. These actions may seek substantial or indeterminate compensatory as well as punitive damages or injunctive relief. The Company is also subject to governmental or regulatory examinations or investigations. The examinations or investigations could result in adverse judgments, settlements, fines, injunctions, restitutions or other relief. For any such matters, the condensed consolidated financial statements include the necessary provisions for losses that the Company believes are probable and estimable. Furthermore, the Company evaluates whether there exist losses which may be reasonably possible and will, if material, make the necessary disclosures.  However, management believes such amounts, both those that are probable and those that are reasonably possible, are not material to the Company's financial condition, operations or cash flows at March 31, 2017.

J. Subsequent Events

On May 1, 2017, GAMCO pre-paid $10 million of the AC 4% PIK Note, which was applied to the $10 million payment due on November 30, 2018.  Of the $80 million principal amount outstanding after this payment, $10 million is due on November 30, 2018, $20 million is due on November 30, 2019, and $50 million is due on November 30, 2020.

On May 3, 2017, the Board of Directors declared its regular quarterly dividend of $0.02 per share to all of its shareholders, payable on July 11, 2017 to shareholders of record on June 27, 2017.

From April 1, 2017 to May 3, 2017, the Company repurchased 12,487 shares at $28.21 per share.  On May 3, 2017, the Board of Directors increased the authorization under the Stock Repurchase Program by an additional 500,000 shares.  As a result, there are 595,571 shares available to be repurchased under this existing buyback plan at May 3, 2017.

ITEM 2: MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (INCLUDING QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK)

Overview

GAMCO, through the Gabelli brand, well known for its Private Market Value (PMV) with a Catalyst^TM investment approach, is a widely-recognized provider of investment advisory services to open-end funds, closed-end funds, and institutional and private wealth management investors principally in the United States.  Through G.distributors, LLC (“G.distributors”), we provide open-end fund distribution.  We generally manage assets on a fully discretionary basis and invest in a variety of U.S. and international securities through various investment styles.  Our revenues are based primarily on the Company’s levels of assets under management and fees associated with our various investment products.

Our revenues are highly correlated to the level of assets under management and fees associated with our various investment products, rather than our own corporate assets.  Assets under management, which are directly influenced by the level and changes of the overall equity markets, can also fluctuate through acquisitions, the creation of new products, the addition of new accounts, or the loss of existing accounts.  Since various equity products have different fees, changes in our business mix may also affect revenues.  At times, the performance of our equity products may differ markedly from popular market indices, and this can also impact our revenues.  General stock market trends will have the greatest impact on our level of assets under management and hence, on revenues.

We conduct our investment advisory business principally through the following subsidiaries: GAMCO Asset Management Inc. (Institutional and Private Wealth Management) and Gabelli Funds, LLC (Funds).  The distribution of our open-end funds is conducted through G.distributors, our broker-dealer subsidiary.

Assets under management (“AUM”) were $41.4 billion as of March 31, 2017, an increase of $1.7 billion, or 4.2%, from December 31, 2016 of $39.7 billion and an increase of $2.7 billion, or 6.8% from the March 31, 2016 AUM of $38.7 billion.  The first quarter 2017 activity consisted of the addition of $1.2 billion for being named the sub-advisor on the TETON Westwood Mighty Mites^SM Fund and the TETON Convertible Securities Fund, net cash outflows of $1.1 billion, $1.7 billion of market appreciation and recurring distributions, net of reinvestments, from open-end and closed-end funds of $0.1 billion.  Average total AUM was $40.6 billion in the 2017 quarter versus $37.5 billion in the prior year period, an increase of 8.3%.

In addition to management fees, we earn incentive fees for certain institutional client assets, certain assets attributable to preferred issues of our closed-end funds and our GDL Fund (NYSE: GDL).  As of March 31, 2017, assets under management with incentive based fees were $2.5 billion unchanged from the $2.5 billion on both December 31, 2016 and March 31, 2016.

DEFERRED COMPENSATION

On December 21, 2015, GAMCO entered into a deferred compensation agreement with Mr. Gabelli whereby his variable compensation for 2016 was in the form of Restricted Stock Units (“RSUs”) determined by the volume-weighted average price (“VWAP”) of the Company’s Class A Stock during 2016 (“2016 RSU”).  When the restrictions lapse on January 1, 2020 (the “Lapse Date”), this RSU agreement can be settled in either cash or stock.  Notwithstanding its ability to settle the RSU agreement in stock, GAMCO currently intends to make a cash payment to Mr. Gabelli on the Lapse Date in an amount, under the terms of the agreement, equal to the number of RSUs valued at the lesser of the VWAP of the Company’s Class A Stock for the 2016 fiscal year or the value on the Lapse Date or, if not a trading day, then the first trading date thereafter.  While the issuance of the award itself does not change Mr. Gabelli’s compensation, the Generally Accepted Accounting Principles (“GAAP”) reporting for his compensation has changed.  The three month 2016 results were materially bolstered by the GAAP-mandated treatment of these RSUs while the three month 2017 results were materially encumbered.  Margins for the first quarter of 2017 and 2016 therefore are not comparable with periods prior to the issuance of the 2016 RSU.  Under GAAP, only 25% of the 2016 RSU expense was recognized in the 2016 year with the remaining 75% amortized as expense in 2017, 2018, and 2019.

On December 23, 2016, GAMCO entered into a second deferred compensation agreement with Mr. Gabelli for the period of January 1, 2017 to June 30, 2017 (“2017 RSU”).  Mr. Gabelli’s compensation for that period will be in the form of an RSU and will vest on July 1, 2018.  For GAAP accounting purposes, the compensation earned from January 1, 2017 to June 30, 2017 will be expensed ratably from January 1, 2017 to June 30, 2018.  As a result, under GAAP, the first half of 2017 will only include 33% of the total 2017 RSU expense with the remaining 67% to be amortized as expense from July 1, 2017 to June 30, 2018.

The GAAP based balance sheets are also impacted; the compensation payable at March 31, 2017 only includes 15/48^ths of the 2016 RSU compensation and 1/3^rd of the 2017 RSU.  At March 31, 2017, the amount of unrecognized compensation was $59.4 million.

The following tables show a reconciliation of our results for the first quarters of 2017 and 2016, and our balance sheet at March 31, 2017 between the GAAP basis and a non-GAAP adjusted basis as if all of the 2016 RSU and 2017 RSU expenses were recognized in 2016 and 2017, respectively.  We believe this adjusted measure is useful in evaluating the ongoing operating results of the Company absent the material adjustment related to the treatment of the deferred compensation agreement.

The following table further illustrates the effect that the GAAP accounting for the compensation deferrals has had to date and will continue to have on our results for 2017 through 2019 under certain assumptions.  For simplicity in arriving at the effect that the 2017 RSU will have, we have assumed that the first quarter RSU expense is predictive of the second quarter 2017 RSU expense, but there is no assurance that this will be the case.

Effect of recording RSU on a GAAP basis versus recording the expense in the period it was earned:

Overview

Income for the quarter was $24.8 million, or $0.82 per fully diluted share, versus $26.0 million, or $0.88 per fully diluted share, in the prior year’s quarter.  The quarter to quarter comparison was impacted by higher revenues and lower other expense, net partially offset by higher variable compensation.

Revenues

Investment advisory and incentive fees for the first quarter 2017 were $75.0 million, 5.9% higher than the 2016 comparative figure of $70.8 million.  Open-end fund revenues increased by 3.8% to $32.5 million from $31.3 million in the first quarter of 2016 driven by a 6.6% increase in average open-end equity AUM.  Our closed-end fund revenues increased 17.6% to $15.4 million in the first quarter 2017 from $13.1 million in 2016 due to a 16.2% increase in non-performance fee based average AUM.  Institutional and private wealth management account revenues, excluding incentive fees, which are generally based on beginning of quarter AUM, rose $0.3 million to $26.2 million from $25.9 million in first quarter 2016.  There were no incentive fees earned during the first quarters of 2017 or 2016.  Revenues relating to the SICAV were $0.9 million in the first quarter of 2017 versus $0.5 million in the first quarter of 2016.

Open-end fund distribution fees and other income were $10.9 million for the first quarter 2017, an increase of $0.4 million or 3.8% from $10.5 million in the prior year period, primarily due to higher average AUM in open-end equity funds that generate distribution fees and decreased level of sales of load shares of open-end funds.

23

Expenses

Compensation costs, which are largely variable, were $25.3 million or 24.6% higher than prior year compensation costs of $20.3 million.  The deferred compensation agreement entered into by the Company with Mr. Gabelli for the first half of 2017 (“2017 RSU”) resulted in variable compensation being reduced by $9.5 million during the first quarter of 2017.  This expense will be recognized ratably over the vesting period through July 1, 2018.  The deferred compensation agreement relating to all of 2016 (“2016 RSU”) resulted in variable compensation for the first quarter of 2017 being increased by $2.5 million while the variable compensation for the first quarter of 2016 was reduced by $10.4 million.  The remainder of the quarter over quarter increase was comprised of a $1.8 million increase in variable compensation related to the increased levels of AUM, a $0.1 million increase in fixed compensation, offset by a $0.3 million decrease in stock compensation expense.

Management fee expense, which is wholly variable and based on pretax income, increased to $2.2 million in the first quarter of 2017 from $1.1 million in the 2016 period.  The management fee expense for the first quarter of 2016 was lower by $2.2 million due to the accounting for the 2016 RSU while the management fee for the first quarter of 2017 was higher by $1.0 million due to the 2016 RSU but $2.8 million lower due to the 2017 RSU.

Distribution costs were $10.9 million, an increase of $0.2 million or 1.9% from $10.7 million in the prior year’s period.

Other operating expenses were $5.1 million in the first quarter of 2017, an increase of $0.7 million, or 15.9%, from $4.4 million in the first quarter of 2016. The research fee paid to G.research increased to $0.8 million in the first quarter of 2017 from $0.4 million in the prior year quarter.

Operating income for the first quarter of 2017 was $42.4 million, a decrease of $2.5 million, or 5.6%, from the $44.9 million in the first quarter of 2016.  Operating income, as a percentage of revenues, was 49.4% in the 2017 quarter as compared to 55.2% in the 2016 quarter.

Other expense

Total other expense, net was an expense of $2.3 million for the first quarter 2017 versus an expense of $2.8 million in the prior year’s quarter.  Net gains from trading securities decreased to $40,000 in the first quarter of 2017.  Interest and dividend income increased to $0.5 million in the first quarter 2017 from $0.4 million in the first quarter 2016.  Interest expense decreased $0.6 million to $2.8 million in the first quarter of 2017 from $3.4 million in the first quarter of 2016 as gross debt at March 31, 2017 was $224.0 million down from the $294.1 million at March 31, 2016.

The effective tax rates (“ETR”) for the three months ended March 31, 2017 and March 31, 2016 were 38.1% and 38.2%, respectively.

LIQUIDITY AND CAPITAL RESOURCES

Our principal assets are highly liquid in nature and consist of cash and cash equivalents, short-term investments and securities held for investment purposes.  Cash and cash equivalents are comprised primarily of 100% U.S. Treasury money market funds managed by GAMCO.

Cash and liquidity requirements have historically been met through cash generated by operating income and our borrowing capacity.  We filed a registration statement with the SEC in 2015 which, among other things, provides us opportunistic flexibility to sell any combination of senior and subordinate debt securities, convertible debt securities, equity securities (including common and preferred stock), and other securities up to a total amount of $500 million.  The shelf is available through April 2018, at which time it may be renewed.

At March 31, 2017, we had total cash and cash equivalents of $88.2 million, an increase of $48.4 million from December 31, 2016 primarily due to the Company’s operating activities described below.  Total debt outstanding at March 31, 2017 was $224 million, consisting of $90 million of a 4% PIK Note due November 30, 2020, $110 million of a 4.5% convertible note due August 15, 2021, and $24.2 million of 5.875% senior notes due 2021.  It is anticipated that the majority of our free cash flow will go towards servicing our debt for the next few years.

For the three months ended March 31, 2017, cash provided by operating activities was $62.8 million, an increase of $32.3 million from cash provided in the prior year period of $30.5 million.  Cash was provided through a decrease in investment advisory fees receivable of $12.5 million, an increase in payable to brokers of $10.0 million, an increase in income taxes payable and deferred tax liabilities of $13.4 million, an increase in compensation payable of $5.1 million, an increase in payable to affiliates of $4.0 million, and $0.1 million from other sources.  Reducing cash was a decrease in net income of $1.2 million, an increase in deferred income taxes of $1.7 million, an increase in income tax receivable and deferred tax assets of $7.8 million, and a decrease to accrued expenses and other liabilities of $2.1 million.  There was no cash provided by investing activities.  Cash used in financing activities in the first three months of 2017 was $14.4 million, including $3.8 million paid for the purchase of treasury stock, and $0.6 million paid in dividends and $10.0 million for the partial repayment for the 4% PIK Note.

For the three months ended March 31, 2016, cash provided by operating activities was $30.5 million.  Cash provided by investing activities, related to proceeds from sales of available for sale securities was $0.3 million in the first three months of 2016.  Cash used in financing activities in the first three months of 2016 was $16.5 million.

Based upon our current level of operations and anticipated growth, we expect that our current cash balances plus cash flows from operating activities and our borrowing capacity will be sufficient to finance our working capital needs for the foreseeable future.  We have no material commitments for capital expenditures.

We have one broker-dealer, G.distributors, which is subject to certain net capital requirements.  G.distributors computes it net capital under the alternative method permitted, which requires minimum net capital of the greater of $250,000 or 2% of the aggregate debit items in the reserve formula for those broker-dealers subject to Rule 15c3-3 promulgated under the Securities Exchange Act of 1934.  The requirement was $250,000 for the broker-dealer at March 31, 2017.  At March 31, 2017, G.distributors had net capital, as defined, of approximately $3.0 million, exceeding the regulatory requirement by approximately $2.8 million.  Net capital requirements for our affiliated broker-dealer may increase in accordance with rules and regulations to the extent they engage in other business activities.

Market Risk

Our primary market risk exposure is to changes in equity prices and interest rates.  Since approximately 96% of our AUM are equities, our financial results are subject to equity market risk as revenues from our investment management services are sensitive to stock market dynamics.  In addition, returns from our proprietary investment portfolio are exposed to interest rate and equity market risk.

The Company’s Chief Investment Officer oversees the proprietary investment portfolios and allocations of proprietary capital among the various strategies.  The Chief Investment Officer and the Board of Directors review the proprietary investment portfolios throughout the year.  Additionally, the Company monitors its proprietary investment portfolios to ensure that they are in compliance with the Company’s guidelines.

Equity Price Risk

The Company earns substantially all of its revenue as advisory and distribution fees from affiliated open-end and closed-end funds and Institutional and Private Wealth Management assets.  Such fees represent a percentage of AUM, and the majority of these assets are in equity investments.  Accordingly, since revenues are proportionate to the value of those investments, a substantial increase or decrease in equity markets overall will have a corresponding effect on the Company's revenues.

With respect to our proprietary investment activities, investments in securities of $33.2 million, $37.3 million and $36.4 million at March 31, 2017, December 31, 2016 and March 31, 2016, respectively, included investments in common stocks of $33.1 million, $37.2 million and $36.4 million, respectively, and investments in closed-end funds of $0.1 million, $0.1 million and $0, respectively.  Of the $33.1 million, $37.2 million and $36.4 million, invested in common stocks at March 31, 2017, December 31, 2016 and March 31, 2016, respectively, $33.1 million, $37.1 million and $36.4 million, respectively, was related to our investment in Westwood Holdings Group Inc.  Securities sold, not yet purchased are financial instruments purchased under agreements to resell and financial instruments sold under agreement to repurchase.  These financial instruments are stated at fair value and are subject to market risks resulting from changes in price and volatility.  At March 31, 2017, December 31, 2016 and March 31, 2016, there were no securities sold, not yet purchased.

The following table provides a sensitivity analysis for our investments in equity securities and partnerships and affiliates which invest primarily in equity securities, excluding arbitrage products for which the principal exposure is to deal closure and not overall market conditions, as of March 31, 2017 and December 31, 2016.  The sensitivity analysis assumes a 10% increase or decrease in the value of these investments (in thousands):

			Fair Value		Fair Value

			10% decrease in		10% increase in
(unaudited)	Fair Value		equity prices		equity prices
At March 31, 2017

At December 31, 2016
Equity price sensitive investments, at fair value	$	37,285	$	33,557	$	41,014

Interest Rate Risk

Our exposure to interest rate risk results, principally, from our investment of excess cash in a sponsored money market fund that holds U.S. Government securities.  These investments are primarily short term in nature, and the carrying value of these investments generally approximates fair value.  Based on March 31, 2017, cash and cash equivalent balance of $88.2 million, a 1% increase in interest rates would increase our interest income by $0.9 million annually.  Given that our current return on these cash equivalent investments in this low interest rate environment is approximately 0.57% annually, an analysis of a 1% decrease is not meaningful.

Critical Accounting Policies and Estimates

The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods.  Actual results could differ significantly from those estimates.  See Note A and the Company’s Critical Accounting Policies in Management’s Discussion and Analysis of Financial Condition and Results of Operations in GAMCO’s 2016 Annual Report on Form 10-K filed with the SEC on March 8, 2017 for details on Critical Accounting Policies.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

In the normal course of its business, GAMCO is exposed to risk of loss due to fluctuations in the securities market and general economy. Management is responsible for identifying, assessing and managing market and other risks. 

Our exposure to pricing risk in equity securities is directly related to our role as financial intermediary and advisor for AUM in our affiliated open-end and closed-end funds, institutional and private wealth management accounts, and investment partnerships as well as our proprietary investment and trading activities.  At March 31, 2017, we had equity investments of $33.2 million.  We may alter our investment holdings from time to time in response to changes in market risks and other factors considered appropriate by management.  The equity investment portfolio is at fair value and will move in line with the equity markets.  The trading portfolio changes are recorded as net gain from investments in the condensed consolidated statements of income while the available for sale portfolio changes are recorded in accumulated other comprehensive income in the condensed consolidated statements of financial condition.

Item 4.  Controls and Procedures

We evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2017.  Disclosure controls and procedures as defined under the Exchange Act Rule 13a-15(e), are designed to ensure that the information we are required to disclose in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time period specified in SEC rules and regulations.  Disclosure controls and procedures include, without limitation, controls and procedures accumulated and communicated to our management, including our Chief Executive Officer (“CEO”) and Co-Chief Accounting Officers (“CAOs”), to allow timely decisions regarding required disclosure.  Our CEO and CAOs participated in this evaluation and concluded that, as of the date of March 31, 2017, our disclosure controls and procedures were effective.

There have been no changes in our internal control over financial reporting as defined by Rule 13a-15(f) that occurred during our most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Forward-Looking Information

Our disclosure and analysis in this report contain some forward-looking statements.  Forward-looking statements give our current expectations or forecasts of future events. You can identify these statements because they do not relate strictly to historical or current facts. They use words such as “anticipate,” “estimate,” “expect,” “project,” “intend,” “plan,” “believe,” and other words and terms of similar meaning. They also appear in any discussion of future operating or financial performance. In particular, these include statements relating to future actions, future performance of our products, expenses, the outcome of any legal proceedings, and financial results.  Although we believe that we are basing our expectations and beliefs on reasonable assumptions within the bounds of what we currently know about our business and operations, there can be no assurance that our actual results will not differ materially from what we expect or believe. Some of the factors that could cause our actual results to differ from our expectations or beliefs include, without limitation: the adverse effect from a decline in the securities markets; a decline in the performance of our products; a general downturn in the economy; changes in government policy or regulation; changes in our ability to attract or retain key employees; and unforeseen costs and other effects related to legal proceedings or investigations of governmental and self-regulatory organizations. We also direct your attention to any more specific discussions of risk contained in our Form 10-Q and other public filings.  We are providing these statements as permitted by the Private Litigation Reform Act of 1995. We do not undertake to update publicly any forward-looking statements if we subsequently learn that we are unlikely to achieve our expectations or if we receive any additional information relating to the subject matters of our forward-looking statements.

Part II:  Other Information

Item 1. Legal Proceedings

From time to time, the Company may be named in legal actions and proceedings.  These actions may seek substantial or indeterminate compensatory as well as punitive damages or injunctive relief.  The Company is also subject to governmental or regulatory examinations or investigations.  The examinations or investigations could result in adverse judgments, settlements, fines, injunctions, restitutions or other relief.  For any such matters, the condensed consolidated financial statements include the necessary provisions for losses that the Company believes are probable and estimable.  Furthermore, the Company evaluates whether there exist losses which may be reasonably possible and will, if material, make the necessary disclosures.  However, management believes such amounts, both those that are probable and those that are reasonably possible, are not material to the Company’s financial condition, operations or cash flows at March 31, 2017.

Significant Accounting Policies [Abstract]

Significant Accounting Policies

A.  Significant Accounting Policies

Basis of Presentation

Unless we have indicated otherwise, or the context otherwise requires, references in this report to “GAMCO Investors, Inc.,” “GAMCO,” “the Company,” “GBL,” “we,” “us” and “our” or similar terms are to GAMCO Investors, Inc., its predecessors and its subsidiaries.

The unaudited interim condensed consolidated financial statements of GAMCO included herein have been prepared in conformity with generally accepted accounting principles (“GAAP”) in the United States for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by U.S. GAAP in the United States for complete financial statements.  In the opinion of management, the unaudited interim condensed consolidated financial statements reflect all adjustments, which are of a normal recurring nature, necessary for a fair presentation of financial position, results of operations and cash flows of GAMCO for the interim periods presented and are not necessarily indicative of a full year’s results.

The interim condensed consolidated financial statements include the accounts of GAMCO and its subsidiaries.  Intercompany accounts and transactions are eliminated.

These interim condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2016.

Use of Estimates

The preparation of the interim condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported on the interim condensed consolidated financial statements and accompanying notes.  Actual results could differ from those estimates.

Recent Accounting Developments

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, "Revenue from Contracts with Customers," which supersedes the revenue recognition requirements in the Accounting Standards Codification ("Codification") Topic 605, Revenue Recognition, and most industry-specific guidance throughout the industry topics of the Codification.  The core principle of the new ASU No. 2014-09 is for companies to recognize revenue from the transfer of goods or services to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services.  The new standard provides a five-step approach to be applied to all contracts with customers and also requires expanded disclosures about revenue recognition.  The ASU is effective for annual reporting periods beginning after December 15, 2017, including interim periods and is to be retrospectively applied.  Early adoption is not permitted.  The Company is currently evaluating this guidance and the impact it will have on its consolidated financial statements.

In January 2016, the FASB issued ASU 2016-01, which amends the guidance in U.S. GAAP on the classification and measurement of financial instruments. Although the ASU retains many current requirements, it significantly revises an entity’s accounting related to (1) the classification and measurement of investments in equity securities and (2) the presentation of certain fair value changes for financial liabilities measured at fair value. The ASU also amends certain disclosure requirements associated with the fair value of financial instruments. For public companies, the new standard is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2017. To adopt the amendments, entities will be required to make a cumulative-effect adjustment to beginning retained earnings as of the beginning of the fiscal year in which the guidance is effective. The Company is currently evaluating this guidance and the impact it will have on its consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, which amends the guidance in U.S. GAAP for the accounting for leases.  ASU 2016-02 requires a lessee to recognize assets and liabilities arising from most operating leases in the condensed consolidated statement of financial position.  ASU 2016-02 is effective beginning January 1, 2019. The Company is currently evaluating this guidance and the impact it will have on its consolidated financial statements.

In March 2016, the FASB issued ASU 2016-09, which simplifies several aspects of the accounting for employee share-based payment transactions for both public and nonpublic entities, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. For public companies, the ASU is effective for annual reporting periods beginning after December 15, 2016, including interim periods within those annual reporting periods.  The Company adopted this guidance on January 1, 2017 without a material impact to the consolidated financial statements.

In August 2016, the FASB issued ASU 2016-15, which adds and clarifies guidance on the classification of certain cash receipts and payments in the consolidated statements of cash flows.  For public companies, the ASU is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those annual reporting periods.  Early adoption is permitted. The Company is currently evaluating this guidance and the impact it will have on its consolidated financial statements.

In January 2017, the FASB issued ASU 2017-04 to simplify the process used to test for goodwill.  Under the new standard, if “the carrying amount of a reporting unit exceeds its fair value, an impairment loss shall be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit.”  For public companies, the ASU is effective for annual and any interim impairment tests for periods beginning after December 15, 2019.  Early adoption is permitted for impairment tests that occur after January 1, 2017. The Company is currently evaluating this guidance and the impact it will have on its condensed consolidated financial statements.

There were no securities sold, not yet purchased at March 31, 2017, December 31, 2016 and March 31, 2016.

Management determines the appropriate classification of debt and equity securities at the time of purchase and reevaluates such designation as of the date of each condensed consolidated statement of financial condition.  Investments in United States Treasury Bills and Notes with maturities of greater than three months at the time of purchase are classified as investments in securities, and those with maturities of three months or less at the time of purchase are classified as cash equivalents.  The portion of investments in securities held for resale in anticipation of short-term market movements are classified as trading securities.  Trading securities are stated at fair value, with any unrealized gains or losses reported in current period earnings.  Available for sale (“AFS”) investments are stated at fair value, with any unrealized gains or losses, net of taxes, reported as a component of equity except for losses deemed to be other than temporary (“OTT”) which are recorded as realized losses in the condensed consolidated statements of income.

The following table identifies all reclassifications out of accumulated other comprehensive income ("AOCI") into income for the three months ended March 31, 2017 and 2016 (in thousands):

Amount					Affected Line Items	Reason for
Reclassified					in the Statements	Reclassification

The following is a summary of the cost, gross unrealized gains, gross unrealized losses and fair value of available for sale investments as of March 31, 2017, December 31, 2016 and March 31, 2016:

A net unrealized loss, net of taxes, for the three months ended March 31, 2017 of $2.6 million has been included in other comprehensive income, a component of equity, at March 31, 2017.  A net unrealized gain, net of taxes, for the three months ended March 31, 2016 of $2.6 million has been included in other comprehensive income, a component of equity, at March 31, 2016.  There were no sales of investments available for sale for the three months ended March 31, 2017. During the three months ended March 31, 2016, proceeds from the sales of investments available for sale were approximately $308,000 and gross gains on the sale of investments available for sale amounted to $2,000 and were reclassified from other comprehensive income into net gain from investments in the condensed consolidated statements of income. There were no realized losses on the sale of investments available for sale for the three months ended March 31, 2017 or March 31, 2016. The basis on which the cost of a security sold is determined using specific identification. Accumulated other comprehensive income on the consolidated statements of equity is primarily comprised of unrealized gains/losses, net of taxes, for AFS securities.

GBL has an established accounting policy and methodology to determine other-than-temporary impairment on available for sale securities.  Under this policy, available for sale securities are evaluated for other than temporary impairments and any impairment charges are recorded in net gain/(loss) from investments on the condensed consolidated statements of income. Management reviews all available for sale securities whose cost exceeds their market value to determine if the impairment is other than temporary.  Management uses qualitative factors such as diversification of the investment, the amount of time that the investment has been impaired, the intent to sell and the severity of the decline in determining whether the impairment is other than temporary.  

There were no investments classified as available for sale that were in an unrealized loss position at March 31, 2017, December 31, 2016 or March 31, 2016.

For the three months ended March 31, 2017 and 2016 there were no losses on available for sale securities that were deemed to be other than temporary.

D. Income Taxes

The effective tax rate ("ETR") for the three months ended March 31, 2017 and March 31, 2016 was 38.1% and 38.2%, respectively.

ASU 2016-09, which was issued in March 2016 and became effective for interim and annual reporting periods beginning after December 15, 2016, simplifies several aspects of accounting for employee share-based payment transactions. Upon adoption of ASU 2016-09 on January 1, 2017, our accounting for excess tax benefits has changed and adopted prospectively, resulting in recognition of excess tax benefits against income tax expenses rather than additional paid-in capital.

4.5% Convertible Note

On August 15, 2016, the Company issued and sold a 5-year, $110 million convertible note (“Convertible Note”).  The note bears interest at a rate of 4.5% per annum and is convertible into shares of the Company’s Class A Common stock (“Class A Stock”) at an initial conversion price of $55.00 per share.  The Convertible Note is initially convertible into two million shares of the Company’s Class A Stock, subject to adjustment pursuant to the terms of the Convertible Note.  The Company is required to repurchase the Convertible Note at the request of the holder on specified dates or after certain circumstances involving a Fundamental Change (as defined in the Convertible Note).  The Company recorded $174,000 of costs in connection with the issuance of the Convertible Note.  GGCP, Inc. (“GGCP”), which owns approximately 63% of the equity interest of the Company, has deposited cash equal to the principal amount of the Note and six months interest (“Initial Deposit”) into an escrow account established pursuant to an escrow agreement by and among GGCP, the Company, the Convertible Note holder and the escrow agent.  In connection with the Initial Deposit made by GGCP, the Company has agreed that GGCP has a right to demand payment in an amount equal to any funds withdrawn from the escrow account by the Convertible Note holder.

AC 4% PIK Note

In connection with the Spin-off of AC on November 30, 2015, the Company issued a $250 million promissory note (the “AC 4% PIK Note”) payable to AC. The AC 4% PIK Note bears interest at 4.0% per annum.  The original principal amount has a maturity date of November 30, 2020.  Interest on the AC 4% PIK Note will accrue from the date of the last interest payment, or if no interest has been paid, from the effective date of the AC 4% PIK Note.  At the election of the Company, payment of interest on the AC 4% PIK Note may be paid in kind (in whole or in part) on the then-outstanding principal amount (a “PIK Amount”) in lieu of cash. All PIK Amounts added to the outstanding principal amount of the AC 4% PIK Note will mature on the fifth anniversary from the date the PIK Amount was added to the outstanding principal of the AC 4% PIK Note. In no event may any interest be paid in kind subsequent to November 30, 2019. The Company may prepay the AC 4% PIK Note (in whole or in part) prior to maturity without penalty.

During the three months ended March 31, 2017, the Company prepaid $10 million of principal of the AC 4% PIK Note against the principal amount due on November 30, 2017.  Of the $90 million principal amount outstanding at March 31, 2017, $20 million is due on November 30, 2018, $20 million is due on November 30, 2019, and $50 million is due on November 30, 2020.

5.875% Senior notes

On May 31, 2011, the Company issued 10-year, $100 million senior notes ("Senior Notes").  The Senior Notes mature on June 1, 2021 and bear interest at 5.875% per annum, payable semi-annually on June 1 and December 1 of each year and commenced on December 1, 2011.  Upon the occurrence of a change of control triggering event, as defined in the indenture, the Company would be required to offer to repurchase the Senior Notes at 101% of their principal amount.

At March 31, 2017, December 31, 2016 and March 31, 2016, the debt was recorded at its face value, net of issuance costs, of $24.1 million, $24.1 million and $24.1 million, respectively.

Loan from GGCP

In connection with the Offer, the Company borrowed $35.0 million from GGCP. The loan had a term of one year and bore interest at 90-day LIBOR plus 3.25%, reset and payable quarterly. On March 18, 2016, the Company paid back $15.0 million of the loan.  During the second quarter of 2016 the Company paid back the remaining $20.0 million of the loan.  At March 31, 2016, the debt was recorded at its face value of $20.0 million.

The fair value of the Company's debt, which is a Level 2 valuation, is estimated based on either quoted market prices for the same or similar issues or on the current rates offered to the Company for debt of the same remaining maturities or using market standard models.  Inputs in these standard models include credit rating, maturity and interest rate.

Voting Rights

The holders of Class A Stock and Class B Common stock ("Class B Stock") have identical rights except that (i) holders of Class A Stock are entitled to one vote per share, while holders of Class B Stock are entitled to ten votes per share on all matters to be voted on by shareholders in general, and (ii) holders of Class A Stock are not eligible to vote on matters relating exclusively to Class B Stock and vice versa.

Stock Award and Incentive Plan

The Company maintains two Plans approved by the shareholders, which are designed to provide incentives which will attract and retain individuals key to the success of GBL through direct or indirect ownership of our common stock. Benefits under the Plans may be granted in any one or a combination of stock options, stock appreciation rights, restricted stock, restricted stock units, stock awards, dividend equivalents and other stock or cash based awards. A maximum of 4.0 million shares of Class A Stock have been reserved for issuance under the Plans by a committee of the Board of Directors responsible for administering the Plans ("Compensation Committee"). Under the Plans, the committee may grant RSAs and either incentive or nonqualified stock options with a term not to exceed ten years from the grant date and at an exercise price that the committee may determine.

As of March 31, 2017, December 31, 2016 and March 31, 2016, there were 420,240 RSA shares, 424,340 RSA shares and 553,100 RSA shares outstanding, respectively, that were previously issued at an average weighted grant price of $65.59, $65.74 and $64.02, respectively. These RSA grants occurred prior to the spin-off of Associated Capital. On November 30, 2015, pursuant to the spin-off, all RSA grant holders received shares of Associated Capital’s Class A common stock as a result of their ownership of their GAMCO unvested RSAs (one share of Associated Capital for each share of GBL). All grants of the RSA shares were recommended by the Company's Chairman, who did not receive a RSA, and approved by the Compensation Committee. This expense, net of estimated forfeitures, is recognized over the vesting period for these awards which is either (1) 30% over three years from the date of grant and 70% over five years from the date of grant or (2) 30% over three years from the date of grant and 10% each year over years four through ten from the date of grant.  During the vesting period, dividends to RSA holders are held for them until the RSA vesting dates and are forfeited if the grantee is no longer employed by the Company on the vesting dates.  Dividends declared on these RSAs, less estimated forfeitures, are charged to retained earnings (deficit) on the declaration date.

ASU 2016-09, which was issued in March 2016 and became effective for interim and annual reporting periods beginning after December 15, 2016, simplifies several aspects of accounting for employee share-based payment transactions. Upon adoption of ASU 2016-09 on January 1, 2017, the Company elected not to change its accounting policy on forfeitures and continue to estimate forfeitures rather than accounting for forfeitures as they occur, an alternative allowed under ASU 2016-09.

For the three months ended March 31, 2017 and March 31, 2016, we recognized stock-based compensation expense of $0.7 million and $1.0 million, respectively.

Identifiable Intangible Assets

H. Identifiable Intangible Assets

As a result of becoming the advisor to the Gabelli Enterprise Mergers and Acquisitions Fund and the associated consideration paid, the Company maintains an identifiable intangible asset of $1.9 million within other assets on the condensed consolidated statements of financial condition at March 31, 2017, December 31, 2016 and March 31, 2016. The investment advisory agreement is subject to annual renewal by the fund's Board of Directors, which the Company expects to be renewed, and the Company does not expect to incur additional expense as a result, which is consistent with other investment advisory agreements entered into by the Company.  The advisory contract is next up for renewal in February 2018. On November 1, 2015, as a result of becoming the advisor to the Bancroft Fund Ltd. and the Ellsworth Growth and Income Fund Ltd. and the associated consideration paid, the Company maintains an identifiable intangible asset of $1.6 million within other assets on the condensed consolidated statement of financial condition at March 31, 2017, December 31, 2016 and March 31, 2016.  The advisory contracts for the Bancroft Fund Ltd. and the Ellsworth Growth and Income Fund Ltd. are both next up for renewal in August 2017. The Company assesses the recoverability of this intangible asset at least annually, or more often should events warrant. There were no indicators of impairment for the three months ended March 31, 2017 or March 31, 2016, and as such there was no impairment analysis performed or charge recorded.

Commitments and Contingencies

I. Commitments and Contingencies

From time to time, the Company may be named in legal actions and proceedings. These actions may seek substantial or indeterminate compensatory as well as punitive damages or injunctive relief. The Company is also subject to governmental or regulatory examinations or investigations. The examinations or investigations could result in adverse judgments, settlements, fines, injunctions, restitutions or other relief. For any such matters, the condensed consolidated financial statements include the necessary provisions for losses that the Company believes are probable and estimable. Furthermore, the Company evaluates whether there exist losses which may be reasonably possible and will, if material, make the necessary disclosures.  However, management believes such amounts, both those that are probable and those that are reasonably possible, are not material to the Company's financial condition, operations or cash flows at March 31, 2017.

Basis of Presentation

Basis of Presentation

Unless we have indicated otherwise, or the context otherwise requires, references in this report to “GAMCO Investors, Inc.,” “GAMCO,” “the Company,” “GBL,” “we,” “us” and “our” or similar terms are to GAMCO Investors, Inc., its predecessors and its subsidiaries.

The unaudited interim condensed consolidated financial statements of GAMCO included herein have been prepared in conformity with generally accepted accounting principles (“GAAP”) in the United States for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by U.S. GAAP in the United States for complete financial statements.  In the opinion of management, the unaudited interim condensed consolidated financial statements reflect all adjustments, which are of a normal recurring nature, necessary for a fair presentation of financial position, results of operations and cash flows of GAMCO for the interim periods presented and are not necessarily indicative of a full year’s results.

The interim condensed consolidated financial statements include the accounts of GAMCO and its subsidiaries.  Intercompany accounts and transactions are eliminated.

These interim condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2016.

Use of Estimates

Use of Estimates

The preparation of the interim condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported on the interim condensed consolidated financial statements and accompanying notes.  Actual results could differ from those estimates.

Recent Accounting Developments

Recent Accounting Developments

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, "Revenue from Contracts with Customers," which supersedes the revenue recognition requirements in the Accounting Standards Codification ("Codification") Topic 605, Revenue Recognition, and most industry-specific guidance throughout the industry topics of the Codification.  The core principle of the new ASU No. 2014-09 is for companies to recognize revenue from the transfer of goods or services to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services.  The new standard provides a five-step approach to be applied to all contracts with customers and also requires expanded disclosures about revenue recognition.  The ASU is effective for annual reporting periods beginning after December 15, 2017, including interim periods and is to be retrospectively applied.  Early adoption is not permitted.  The Company is currently evaluating this guidance and the impact it will have on its consolidated financial statements.

In January 2016, the FASB issued ASU 2016-01, which amends the guidance in U.S. GAAP on the classification and measurement of financial instruments. Although the ASU retains many current requirements, it significantly revises an entity’s accounting related to (1) the classification and measurement of investments in equity securities and (2) the presentation of certain fair value changes for financial liabilities measured at fair value. The ASU also amends certain disclosure requirements associated with the fair value of financial instruments. For public companies, the new standard is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2017. To adopt the amendments, entities will be required to make a cumulative-effect adjustment to beginning retained earnings as of the beginning of the fiscal year in which the guidance is effective. The Company is currently evaluating this guidance and the impact it will have on its consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, which amends the guidance in U.S. GAAP for the accounting for leases.  ASU 2016-02 requires a lessee to recognize assets and liabilities arising from most operating leases in the condensed consolidated statement of financial position.  ASU 2016-02 is effective beginning January 1, 2019. The Company is currently evaluating this guidance and the impact it will have on its consolidated financial statements.

In March 2016, the FASB issued ASU 2016-09, which simplifies several aspects of the accounting for employee share-based payment transactions for both public and nonpublic entities, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. For public companies, the ASU is effective for annual reporting periods beginning after December 15, 2016, including interim periods within those annual reporting periods.  The Company adopted this guidance on January 1, 2017 without a material impact to the consolidated financial statements.

In August 2016, the FASB issued ASU 2016-15, which adds and clarifies guidance on the classification of certain cash receipts and payments in the consolidated statements of cash flows.  For public companies, the ASU is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those annual reporting periods.  Early adoption is permitted. The Company is currently evaluating this guidance and the impact it will have on its consolidated financial statements.

In January 2017, the FASB issued ASU 2017-04 to simplify the process used to test for goodwill.  Under the new standard, if “the carrying amount of a reporting unit exceeds its fair value, an impairment loss shall be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit.”  For public companies, the ASU is effective for annual and any interim impairment tests for periods beginning after December 15, 2019.  Early adoption is permitted for impairment tests that occur after January 1, 2017. The Company is currently evaluating this guidance and the impact it will have on its condensed consolidated financial statements.
