NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

March 31, 2018

(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, 2017.

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 to receive 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.  In March 2016, the FASB issued revised guidance which clarifies the guidance related to (a) determining the appropriate unit of account under the revenue standard’s principal versus agent guidance and (b) applying the indicators of whether an entity is a principal or an agent in accordance with the revenue standard’s control principle. In April 2016, the FASB issued an amendment to provide more detailed guidance including additional implementation guidance and examples related to (a) identifying performance obligations and (b) licenses of intellectual property.  In May 2016, the FASB amended the standard to clarify the guidance on (a) assessing collectability, (b) presenting sales taxes, (c) measuring noncash consideration, and (d) certain transition matters.  The Company adopted this guidance on January 1, 2018 and adopted the modified retrospective approach.  The Company’s implementation analysis has been completed, and we have identified similar performance obligations under this guidance as compared with deliverables and separate units of account previously identified under Topic 605.  As a result, the timing of the recognition of our revenue remains the same as under Topic 605, and therefore the adoption does not have any effect on the timing of the recognition of revenue.  See Note B. Revenue Recognition for the disclosures required by ASU 2014-09.

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. In addition, the FASB clarified guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. To adopt the amendments, entities are 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 adopted this guidance on January 1, 2018 and reclassified $12.1 million out of Accumulated Other Comprehensive Income and into Retained Earnings.  Effective January 1, 2018, changes in the fair value of the Company’s investments in equity securities are reported through earnings in the net gain (loss) from investments line in the condensed consolidated statements of income rather than through other comprehensive income.

10

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. It requires these operating leases to be recorded on the balance sheet as right of use assets and offsetting lease liability obligations.  This new guidance will be effective for the Company’s first quarter of 2019. The Company is currently evaluating this guidance and the impact it will have on its consolidated financial statements and related disclosures.

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.  This guidance is intended to unify the currently diverse presentations and classifications, which address eight classification issues related to the statement of cash flows, including debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, distributions received from equity method investees, beneficial interests in securitization transactions, and separately identifiable cash flows and application of the predominance principle.  The Company adopted this guidance on January 1, 2018 without a material impact to the consolidated financial statements.

In January 2017, the FASB issued ASU 2017-04 to simplify the process used to test for goodwill impairment.  A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. This new guidance will be effective for the Company’s first quarter of 2020. The Company is currently evaluating the potential effect of this new guidance on its consolidated financial statements and related disclosures.

On May 10, 2017, the FASB issued ASU 2017-09, which amends the scope of modification accounting for share-based payment arrangements.  The ASU provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under ASC 718.  Specifically, an entity would not apply modification accounting if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification.  For all entities, the ASU is effective for annual reporting periods, including interim periods within those annual reporting periods, beginning after December 15, 2017.  The Company adopted this guidance on January 1, 2018 without a material impact to the consolidated financial statements.

B.  Revenue Recognition

The revenue streams in the discussion below and in the table on page 13 include those that are within the scope of ASU 2014-09.  Those revenues deemed out of scope and excluded are: investment gains and losses generated from the Company’s proprietary trading activities, dividend income, and interest income.  In all cases for all revenue streams discussed below, the revenue generated is from a single transaction price, and there is no need to allocate the amounts across more than a single revenue stream.  The customer for all revenues derived from open-end and closed-end funds described in detail below has been determined to be the fund itself and not the ultimate underlying investor in the fund.  The Company has identified similar performance obligations under ASU 2014-09 as compared with ASC Topic 605.  As a result, the timing of the recognition of our revenue remains the same under this new guidance as it was under ASC Topic 605.

Significant Judgments that affect the amounts and timing of revenue recognition:

The Company’s analysis of the timing of revenue recognition for each revenue stream is based upon an analysis of current contract terms.  Performance obligations could, however, change from time to time if and when existing contracts are modified or new contracts are entered into.  These changes could potentially affect the timing of satisfaction of performance obligations, the determination of the transaction price, and the allocation of the price to performance obligations.  In the case of the revenue streams discussed below, the performance obligation is satisfied at a point in time and in no instance is it satisfied over a period of time.  In the case of performance correlated revenues, the point in time is the end of the measurement period as defined within the contract and subject to reduction to zero on the date where the measurement period ends even if the performance benchmarks were exceeded during the intervening period.  Thus, for performance correlated revenues, the performance obligation is satisfied at a single point in time.  The judgments outlined below, where the determination as to these factors is discussed in detail, are continually reviewed and monitored by the Company when new contracts or contract modifications occur.  Transaction price is in all instances formulaic and not subject to significant (or any) judgment at the current time.  The allowance for doubtful accounts is subject to judgment.  There were no impairment losses (allowance for doubtful accounts) on any receivables from any revenue stream at the end of the current period.

11

Advisory Fee Revenues

Advisory fees for open-end funds, closed-end funds, sub-advisory accounts and SICAVs are earned based on predetermined percentages of the average net assets of the individual funds and are recognized as revenues as the related services are performed.  Fees for open-end funds, sub-advisory accounts and SICAVs are computed on a daily basis on average net assets under management ("AUM"), while fees for closed-end funds are computed on average weekly net AUM.  These fees are received in cash after the end of each monthly period within 30 days.  The revenue recognition occurs daily as the performance obligation (advising the fund) is met continuously.  There is a risk of non-payment, and therefore an impairment loss on these receivables is possible at each reporting date.  There were no such impairment losses for the current period.

Advisory fees for Institutional & Private Wealth Management accounts are earned based on predetermined percentages of the average AUM and are generally computed quarterly based on account values at the end of the preceding quarter.  The revenue recognition occurs daily as the performance obligation (advising the client portfolio) is met continuously.  These fees are received in cash, typically within 60 days of the client being billed.  There is a risk of non-payment, and therefore an impairment loss on these receivables is possible at each reporting date.  There were no such impairment losses for the current period.

Performance Correlated Revenues

Investment advisory fees earned on many of the closed-end funds' preferred shares are earned at year-end if the total return to common shareholders of the closed-end fund for the calendar year exceeds the dividend rate of the preferred shares.  These fees are recognized at the end of the measurement period which coincides with the calendar year.  The fee would also be earned and the contract period ended at any interim point in time that the preferred shares are redeemed.  These fees are received in cash after the end of the measurement period within 30 days.

Certain closed-end funds have performance fees that are earned at the end of the fund fiscal year to the extent the total return of each fund exceeds a benchmark return.  The fee would also be earned and the contract period ended at any interim point in time that the fund was to repurchase shares.  These fees are received in cash after the end of the measurement period within 30 days.

We also receive incentive fees from certain institutional clients which are based upon exceeding a specific benchmark index or indices.  These fees are recognized at the end of the stipulated contract period, which is generally annually, for the respective account.  The fee would also be earned and the contract period ended at any interim point in time that the client terminated its relationship with us.  These fees are received in cash after the end of the measurement period typically within 60 days.

Certain funds within the SICAV structure may charge a performance fee.  These fees are recognized at the end of the measurement period which coincides with the calendar year or upon redemption.  These fees are received in cash after the end of the measurement period within 30 days.

In all cases of the performance correlated revenue, revenue recognition is delayed until the performance obligation has been met (the measurement period has concluded and the hurdle has been exceeded).  There is a risk of non-payment, and therefore an impairment loss on these receivables is possible at each reporting date.  There were no such impairment losses for the current period.

Distribution Fees and Other Income

Distribution fees and other income primarily includes distribution fee revenue earned in accordance with Rule 12b-1 of the Company Act, as amended, along with sales charges and underwriting fees associated with the sale of the mutual funds.  Distribution plan fees are computed based on average daily net assets of each fund and are accrued for during the period in which they are earned.  These fees are received in cash after the end of each monthly period within 30 days.  In evaluating the appropriate timing of the recognition of these fees, we applied the guidance on up-front fees to determine whether such fees are related to the transfer of a promised service (a distinct performance obligation).  Our conclusion is that the service being provided by G.distributors to the customer in exchange for the fee is for the initial distribution of the funds and is completed at the time of the sale.  As such, there is no portion of this revenue that needs to be deferred because the performance obligation is complete, and revenue recognition coincides with the completion.  The Company reached the same conclusion with regard to sales charges and underwriting fees associated with the sale of the mutual funds - neither of which is material in the aggregate to the Company's revenue streams.  There is a risk of non-payment, and therefore an impairment loss on these receivables is possible at each reporting date.  There were no such impairment losses for the current period.

C.  Investment in Securities

Effective with the Company’s adoption of ASU 2016-01 on January 1, 2018, the Company carries all investments in equity securities at fair value through net income (“FVTNI”) which approximates market value.  The Company has no securities that qualify for the equity method or for consolidation of the investee of for which the Company has elected the practicality exception to fair value measurement.

Investments in securities at March 31, 2018, December 31, 2017 and March 31, 2017 consisted of the following:

There were no securities sold, not yet purchased at March 31, 2018, December 31, 2017 and March 31, 2017.

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 were classified as trading securities for the periods ended December 31, 2017 and March 31, 2017.  Securities carried at FVTNI for the March 31, 2018 period-end and trading securities in the periods ending December 31, 2017 and March 31, 2017 are stated at fair value, with any unrealized gains or losses reported in current period earnings.  Available for sale (“AFS”) investments for the periods ended December 31, 2017 and March 31, 2017 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 were recorded as realized losses in the condensed consolidated statements of income.

13

Effective January 1, 2018, the Company adopted ASU 2016-01, which eliminated available for sale accounting and resulted in the reclassification of $12.1 million, net of tax, out of accumulated comprehensive income and into retained earnings in the condensed consolidated statement of financial condition.  As a result, for the three months ended March 31, 2018, changes in the fair value of the Company’s entire investment portfolio are now recorded in the net gain (loss) from investments line in the condensed consolidated statements of income rather than through other comprehensive income.

The following table identifies all reclassifications out of accumulated other comprehensive income ("AOCI") into income for the three months ended March 31, 2017 (in thousands).  (No disclosure is needed for the three months ended March 31, 2018 due to the adoption of ASU 2016-01.)

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.  There were no sales of investments available for sale for the three months ended March 31, 2017.  There were no realized losses on the sale of investments available for sale for the three months ended March 31, 2017. The basis on which the cost of a security sold is determined using specific identification. Accumulated other comprehensive income in the condensed consolidated statements of equity is primarily comprised of unrealized gains/losses, net of taxes, for AFS securities.

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

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

During the quarters ended March 31, 2018 and 2017, there were no transfers between any Level 1 and Level 2 holdings, or between Level 1 and Level 3 holdings.

E. Income Taxes

The effective tax rate ("ETR") for the three months ended March 31, 2018 and March 31, 2017 was 22.6% and 38.1%, respectively.

The decline in the ETR is almost exclusively due to the lower Federal tax rate under the Tax Cuts and Jobs Act which lowered our Federal tax rate from 35% to 21%, effective January 1, 2018.

4.5% Convertible Note

On August 15, 2016, the Company issued and sold a 5-year, $110 million convertible note (“Convertible Note”).  The note bore interest at a rate of 4.5% per annum and was 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 was 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 was 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.  On November 20, 2017, the Company and the Convertible Note holder agreed to amend the Convertible Note to allow for an early redemption if the Company paid the Convertible Note holder 103% of the unpaid principal plus all accrued but unpaid interest on the redemption date.  On November 21, 2017, the Company redeemed the Convertible Note for $114.6 million.  The payment was equal to 103% of the unpaid principal amount of the note plus accrued interest.  As a result, the Company recorded a loss on extinguishment of debt of $3.3 million and expensed the remaining $135,000 of issuance costs.

GGCP, Inc. (“GGCP”), which owns approximately 63% of the equity interest of the Company, initially 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 (the “Escrow Agreement”).  In connection with the Initial Deposit made by GGCP, the Company had agreed that GGCP had a right to demand payment in an amount equal to any funds withdrawn from the escrow account by the Convertible Note holder.  On September 30, 2017, in connection with an amendment to the Escrow Agreement and in exchange for approximately 53% of the assets in the escrow account, the Company paid GGCP $60 million.  On November 21, 2017, the Company paid GGCP $53 million for the remaining 47% of the assets in the escrow account that it did not previously own.

16

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, 2018, the Company prepaid $10 million of principal of the AC 4% PIK Note against the principal amount due on November 30, 2020.  During the three months ended March 31, 2017, the Company prepaid $10 million of principal of the AC 4% PIK Note.

Subsequent to March 31, 2018, the Company paid an additional $10 million of principal, thereby reducing the amount outstanding to $30 million, all of which is due on November 30, 2020.

AC 1.6% Note

On December 26, 2017, to finance tax payments and for working capital purposes, the Company borrowed $15 million from AC in exchange for a note that bore interest at 1.6% per annum.  On February 28, 2018, the date of maturity, the Company repaid the entire principal and accrued interest.

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, 2018, December 31, 2017 and March 31, 2017, the debt was recorded at its face value, net of issuance costs, of $24.2 million, $24.1 million and $24.1 million, respectively.

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.  The Company has not elected the fair value option for its debt, and, therefore, the provisions of ASU 2016-01 (adopted by the Company on January 1, 2018) related to instrument-specific credit risk are not applicable.

H. Stockholders’ Equity

Shares outstanding were 28.9 million, 29.0 million and 29.3 million on March 31, 2018, December 31, 2017 and March 31, 2017, 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 one Plan approved by the shareholders, which is 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 7.5 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 December 31, 2017 and March 31, 2017, there were 19,400 RSA shares and 420,240 RSA shares outstanding, respectively, that were previously issued at an average weighted grant price of $65.67 and $65.59, respectively. These RSA grants occurred prior to the spin-off of Associated Capital (“AC”).  There were no RSAs outstanding as of March 31, 2018.  On November 30, 2015, pursuant to the spin-off, all RSA grant holders received shares of AC’s Class A common stock as a result of their ownership of their GAMCO unvested RSAs (one share of AC 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.

On January 5, 2018, the Compensation Committee of GBL accelerated the vesting relating to the remaining 19,400 RSAs outstanding.  As a result, GBL recorded an incremental $0.2 million of stock-based compensation expense during the first quarter of 2018.

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.  The Company’s accounting treatment for excess tax benefits or tax deficiencies also changed with the adoption of ASU 2016-09 on January 1, 2017. Excess tax benefits or tax deficiencies are now required to be recorded within the income tax expense line in the consolidated statement of income rather than to additional paid-in capital within the condensed consolidated statement of financial condition.  During the three months ended March 31, 2018, the Company reduced previously recorded tax benefits relating to RSA expense by $0.1 million on RSAs that vested.  There were no RSA vestings for the three months ended March 31, 2017.

For the three months ended March 31, 2018 and March 31, 2017, we recognized stock-based compensation expense of $0.2 million and $0.7 million, respectively. The three month amount for 2018 is entirely related to the GBL RSA accelerated vesting mentioned above.

As of March 31, 2018, there are no RSAs outstanding, and therefore there is no unrecognized stock compensation expense related to non-vested RSAs.

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, 2018, the Company repurchased 119,334 shares at an average price per share of $27.71.  From the inception of the program through March 31, 2018, 10,505,200 shares have been repurchased at an average price of $43.45 per share.  At March 31, 2018, the total shares available under the program to be repurchased in the future were 554,960.

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 expired in early May 2018.  As of March 31, 2018, $500 million is available on the shelf.  The Company filed a new shelf registration statement with the SEC in April 2018.

I. 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 in the condensed consolidated statements of financial condition at March 31, 2018, December 31, 2017 and March 31, 2017. 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 2019. 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 in the condensed consolidated statement of financial condition at March 31, 2018, December 31, 2017 and March 31, 2017.  The advisory contracts for the Bancroft Fund Ltd. and the Ellsworth Growth and Income Fund Ltd. are both next up for renewal in August 2018. 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, 2018 or March 31, 2017, and as such there was no impairment analysis performed or charge recorded.

J. 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, 2018.

K. Related Party Transactions

On February 23, 2018, the Chief Executive Officer of the Company elected to waive all of his compensation that he would have otherwise been entitled to for the period of March 1, 2018 through December 31, 2018.  For the three months ended March 31, 2018, the waiver reduced compensation by $4.9 million and management fee by $1.7 million.  No projection can be reasonably provided as to the amount of compensation foregone by the waiver for April 1, 2018 through December 31, 2018 as the entirety of the CEO’s compensation is variably based.

L. Subsequent Events

On April 4, 2018, the Company prepaid $10 million of principal of the AC 4% PIK Note, against the principal amount due on November 30, 2020 reducing the principal outstanding to $30 million.

On April 4, 2018, the Compensation Committee of the Board of Directors authorized the granting of 270,500 RSAs.  The RSAs will vest 30% after the third anniversary date and 70% after the fifth anniversary date.

On April 23, 2018, the Securities and Exchange Commission declared the Company’s shelf registration statement on Form S-3 effective.  The shelf registration statement, which replaces the shelf registration statement from 2015, provides the Company with the ability to issue $500 million of debt or equity securities and expires in three years.

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, Exchange Traded Managed Funds (“ETMFs”), and institutional and private wealth management investors principally in the United States.  Through G.distributors, LLC (“G.distributors”), we provide open-end fund and ETMF 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 including value, growth, non-market correlated, and convertible securities.  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 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 an 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 and ETMFs is conducted through G.distributors, our broker-dealer subsidiary.

Assets under management (“AUM”) were $40.9 billion as of March 31, 2018, a slippage of $0.8 billion, or 2.0% from the March 31, 2017 AUM of $41.7 billion and a decrease of $2.2 billion, or 5.1%, from December 31, 2017 of $43.1 billion.  The first quarter 2018 activity consisted of net cash outflows of $1.1 billion, $951 million of market depreciation and recurring distributions, net of reinvestments, from open-end and closed-end funds of $121 million.  Average total AUM was $42.5 billion in the 2018 quarter versus $40.9 billion in the prior year period, an increase of 3.9%.

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 two closed-end funds.  As of March 31, 2018, assets under management with incentive based fees were $2.7 billion, $0.2 billion less than the $2.9 billion on March 31, 2017.

DEFERRED COMPENSATION

As previously disclosed, the Company has deferred the cash compensation of the Chief Executive Officer relating to all of 2016 (“2016 DCCA”), the first half of 2017 (“First Half 2017 DCCA”), and the fourth quarter of 2017 (“Fourth Quarter 2017 DCCA”) to provide the Company with flexibility to pay down debt.  We have made substantial progress toward this objective, having reduced our debt since the November 2015 spin-off of AC, resulting in Standard & Poor’s recent revision of its outlook to stable from negative and reaffirmation of our debt rating of BBB-.

Notwithstanding its ability to settle these agreements in stock, GAMCO currently intends to make cash payments to Mr. Gabelli on the respective vesting dates.  While the agreements did not change Mr. Gabelli’s compensation, GAAP reporting for his compensation did change due to the ratable vesting.

The DCCAs defer the Chief Executive Officer’s compensation expense by amortizing it over each DCCA’s respective vesting period.  The Chief Executive Officer is not entitled to receive the compensation until the end of the vesting period, so generally accepted accounting principles (“GAAP”) specify this treatment of the expense.  The 2016 DCCA is expensed ratably over 4 years, the First Half 2017 DCCA is expensed ratably over 18 months, and the Fourth Quarter DCCA will be expensed ratably over 18 months.

Because the GAAP reporting of the DCCAs granted to the CEO tracks vesting, compensation expense and management fee expense in the year of grant is lower than compensation expense and management fee expense in future periods to the extent that future periods contain the vesting of the prior year’s DCCA compensation on top of the normal compensation for the current year period which has not been deferred.  In 2016, the full amount of the compensation was deferred, and expense was recorded for the 25% vesting in that year.  In the first six months of 2017, the ratable vesting continued for the 2016 compensation, and the new First Half 2017 DCCA grant resulted in compensation for the first six months of 2017 being deferred and expense being recorded for 33% vesting in that period.  The CEO’s third quarter compensation was not deferred so 100% of the CEO’s compensation for that period was recorded together with the ratable portions of the vestings of the 2016 DCCA and the First Half 2017 DCCA.  So there is a compounding effect in future periods when there are both current period compensation that has not been deferred and prior period compensation that is being ratably vested.

Accordingly, this vesting schedule resulted in a $5.2 million increase in compensation expense in the first quarter 2018 versus the comparable 2017 period’s amounts as well as a $3.9 million increase in management fee expense in the first quarter 2018 as compared to the 2017 period’s amounts.

The following tables show the non-cash amortization and EPS impact of the DCCAs by quarter.  The amortization amount of future periods assumes that the stock price of GBL is unchanged from March 31, 2018.

The GAAP based balance sheets are also impacted; the compensation payable at March 31, 2018 only includes the vested portion of the compensation subject to the DCCAs.  At March 31, 2018, the amount of unrecognized compensation was $39.1 million.

The following tables show a reconciliation of our results for the first quarters of 2018 and 2017, and our balance sheet at March 31, 2018 between the GAAP basis and a non-GAAP adjusted basis as if all of the 2016 DCCA, the First Half 2017 DCCA, and the Fourth Quarter 2017 DCCA expense were recognized in 2016, 2017 and 2018, respectively, without regard to the vesting schedule.  We believe the non-GAAP financial measures below provide relevant and meaningful information to investors about our core operating results.  These measures have been established in order to increase transparency for the purpose of evaluating our core business, for comparing results with prior period results, and to enable more appropriate comparisons with industry peers.  However, non-GAAP financial measures should not be considered a substitute for financial measures calculated in accordance with U.S. GAAP and may be calculated differently by other companies.  The following schedules reconcile U.S. GAAP financial measures to non-GAAP measures for the three months ended March 31, 2018 and 2017 as well as at March 31, 2018.

Overview

Net income for the quarter was $27.3 million, or $0.94 per fully diluted share, versus $24.8 million, or $0.82 per fully diluted share, in the prior year’s quarter.  The quarter to quarter comparison was impacted by higher revenues partially offset by higher variable compensation and higher other expense, net.

Revenues

Investment advisory and incentive fees for the first quarter 2018 were $77.3 million, 3.1% higher than the 2017 comparative figure of $75.0 million.  Open-end fund revenues increased by 1.2% to $32.9 million from $32.5 million in the first quarter of 2017.  Our closed-end fund revenues increased 11.0% to $17.1 million in the first quarter 2018 from $15.4 million in 2017.  Institutional and private wealth management account revenues, excluding incentive fees, which are generally based on beginning of quarter AUM, declined $0.2 million to $26.0 million from $26.2 million in the first quarter of 2017.  There were no incentive fees earned during the first quarters of 2018 or 2017.  We recognize incentive fees only when the earning period for them is complete.  Revenues relating to the SICAV were $1.3 million in the first quarter of 2018 versus $0.9 million in the first quarter of 2017.

Open-end fund distribution fees and other income were $10.1 million for the first quarter 2018, a decrease of $0.8 million or 7.3% from $10.9 million in the prior year period, primarily due to lower average AUM in open-end equity funds that generate distribution fees.

26

Expenses

Compensation costs, which are largely variable, were $26.0 million or 2.8% higher than prior year compensation costs of $25.3 million.  The amortization of the DCCAs resulted in a $5.2 million increase year over year, mostly offset by the CEO waiver which reduced first quarter of 2018 compensation expense by $4.9 million.

The remainder of the quarter over quarter increase was comprised of a $0.1 million increase in variable compensation related to the increased levels of AUM, a $0.8 million increase in fixed compensation, and a $0.5 million decrease in stock compensation expense.

Management fee expense, which is wholly variable and based on pretax income, increased to $4.6 million in the first quarter of 2018 from $2.2 million in the 2017 period.  Once again, this increase is primarily due to the accounting for the vesting of the DCCAs.  The DCCAs affected management fee expense, which is part of the CEO’s DCCAs, in a similar fashion to the compensation expense with the vesting schedule resulting in a $3.9 million increase in management fee expense in the first quarter 2018 as compared with the first quarter 2017.  The CEO waiver reduced management fee expense by $1.7 million in the first quarter of 2018, while the remaining $0.2 increase in the year-over-year comparison is due to the increase in pre-tax income on which the management fee is based.

Distribution costs were $10.2 million, a decrease of $0.7 million or 6.4% from $10.9 million in the prior year’s period.

Other operating expenses were $5.5 million in the first quarter of 2018, an increase of $0.4 million, or 7.8%, from $5.1 million in the first quarter of 2017.

Operating income for the first quarter of 2018 was $41.3 million, a decrease of $1.1 million, or 2.6%, from the $42.4 million in the first quarter of 2017.  Operating income, as a percentage of revenues, was 47.2% in the 2018 quarter as compared to 49.4% in the 2017 quarter.

Other expense

Total other expense, net was an expense of $6.1 million for the first quarter 2018 versus an expense of $2.3 million in the prior year’s quarter.  Net losses from investments were $5.3 million in the first quarter of 2018 versus gains of $40,000 in the first quarter of 2017.  The losses in the first quarter of 2018 include $5.4 million for securities which were carried as AFS securities (with gains and losses through other comprehensive income) prior to the adoption of ASU 2016-01 on January 1, 2018.  Interest and dividend income was $0.5 million in both the first quarter 2018 and 2017.  Interest expense was $1.2 million in the first quarter of 2018 versus $2.8 million in the first quarter of 2017.

The effective tax rates (“ETR”) for the three months ended March 31, 2018 and March 31, 2017 were 22.6% and 38.1%, respectively.  The decline in the ETR is almost exclusively due to the lower Federal tax rate under the Tax Cuts and Jobs Act which lowered our Federal tax rate from 35% to 21%, effective January 1, 2018.

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 that was declared effective in April 2018, replacing the shelf that was set to expire in May 2018.  The shelf 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 2021, at which time it may be renewed.

On February 23, 2018, the Company announced that its CEO elected to waive all of his compensation that he would otherwise have been entitled to for the period from March 1, 2018 through December 31, 2018.  As a result of this waiver, there was $6.6 million of compensation waived by the CEO for the first quarter of 2018.

At March 31, 2018, we had total unrestricted cash and cash equivalents of $27.4 million, an increase of $9.6 million from December 31, 2017 primarily due to the Company’s operating activities described below.  Total debt outstanding at March 31, 2018 was $64.2 million, consisting of $40 million of a 4% PIK Note due November 30, 2020, 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 and deferred compensation payable in the near future.

For the three months ended March 31, 2018, cash provided by operating activities was $53.0 million, a decrease of $9.8 million from cash provided in the prior year period of $62.8 million.  Cash was provided through a decrease in investments in securities of $5.4 million, a decrease in deferred income taxes of $2.3 million, a decrease in income tax receivable and deferred tax assets of $6.2 million, an increase in net income of $2.4 million, an increase in compensation payable of $1.5 million, and $1.0 million from other sources.  Reducing cash was a decrease in income taxes payable and deferred tax liabilities of $15.5 million, a decrease in payable to brokers of $10.2 million, an increase in investment advisory fees receivable of $2.4 million, and a decrease of $0.5 million in stock based compensation expense.  Cash used in financing activities in the first three months of 2018 was $43.4 million, including $3.3 million paid for the purchase of treasury stock, and $0.6 million paid in dividends, $15.0 million for the repayment of the 1.6% AC Note, $10.0 million for the partial repurchase of the 4% PIK Note, $5 million for margin loan borrowings and $19.5 million for margin loan payments.  There was no cash provided by or used in investing activities for the first three months of 2018.

For the three months ended March 31, 2017, cash provided by operating activities was $62.8 million.  Cash used in financing activities in the first three months of 2017 was $14.4 million.  There was no cash provided by or used in investing activities for the first three months of 2017.

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, 2018.  At March 31, 2018, G.distributors had net capital, as defined, of approximately $2.6 million, exceeding the regulatory requirement by approximately $2.4 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 95% 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.

28

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 $31.4 million, $36.8 million and $33.2 million at March 31, 2018, December 31, 2017 and March 31, 2017, respectively, included investments in common stocks of $31.3 million, $36.7 million and $33.1 million, respectively, and investments in closed-end funds of $0.1 million, $0.1 million and $0.1 million, respectively.  Of the $31.3 million, $36.7 million and $33.1 million, invested in common stocks at March 31, 2018, December 31, 2017 and March 31, 2017, respectively, $31.3 million, $36.6 million and $33.1 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, 2018, December 31, 2017 and March 31, 2017, there were no securities sold, not yet purchased.

The following table provides a sensitivity analysis for our investments in equity securities as of March 31, 2018 and December 31, 2017.  The sensitivity analysis assumes a 10% increase or decrease in the value of these investments (in thousands):

				Fair Value			Fair Value
				assuming			assuming
				10% decrease in			10% increase in
(unaudited)	Fair Value			equity prices			equity prices
At March 31, 2018
Equity price sensitive investments, at fair value		$	31,407		$	28,266		$	34,548
At December 31, 2017
Equity price sensitive investments, at fair value		$	36,790		$	33,111		$	40,470

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, 2018, cash and cash equivalent balance of $27.4 million, a 1% increase in interest rates would increase our interest income by $0.3 million annually while a 1% decrease would reduce our interest income by $0.3 million annually

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 2017 Annual Report on Form 10-K filed with the SEC on March 8, 2018 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, 2018, we had equity investments of $31.4 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 securities investment portfolio is at fair value and will move in line with the equity markets.  The equity securities investment portfolio changes are recorded as net gain (loss) from investments in the condensed consolidated statements of income.

Item 4.  Controls and Procedures

We evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2018.  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, 2018, 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, 2018.

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, 2017.

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 to receive 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.  In March 2016, the FASB issued revised guidance which clarifies the guidance related to (a) determining the appropriate unit of account under the revenue standard’s principal versus agent guidance and (b) applying the indicators of whether an entity is a principal or an agent in accordance with the revenue standard’s control principle. In April 2016, the FASB issued an amendment to provide more detailed guidance including additional implementation guidance and examples related to (a) identifying performance obligations and (b) licenses of intellectual property.  In May 2016, the FASB amended the standard to clarify the guidance on (a) assessing collectability, (b) presenting sales taxes, (c) measuring noncash consideration, and (d) certain transition matters.  The Company adopted this guidance on January 1, 2018 and adopted the modified retrospective approach.  The Company’s implementation analysis has been completed, and we have identified similar performance obligations under this guidance as compared with deliverables and separate units of account previously identified under Topic 605.  As a result, the timing of the recognition of our revenue remains the same as under Topic 605, and therefore the adoption does not have any effect on the timing of the recognition of revenue.  See Note B. Revenue Recognition for the disclosures required by ASU 2014-09.

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. In addition, the FASB clarified guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. To adopt the amendments, entities are 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 adopted this guidance on January 1, 2018 and reclassified $12.1 million out of Accumulated Other Comprehensive Income and into Retained Earnings.  Effective January 1, 2018, changes in the fair value of the Company’s investments in equity securities are reported through earnings in the net gain (loss) from investments line in the condensed consolidated statements of income rather than through other comprehensive income.

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. It requires these operating leases to be recorded on the balance sheet as right of use assets and offsetting lease liability obligations.  This new guidance will be effective for the Company’s first quarter of 2019. The Company is currently evaluating this guidance and the impact it will have on its consolidated financial statements and related disclosures.

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.  This guidance is intended to unify the currently diverse presentations and classifications, which address eight classification issues related to the statement of cash flows, including debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, distributions received from equity method investees, beneficial interests in securitization transactions, and separately identifiable cash flows and application of the predominance principle.  The Company adopted this guidance on January 1, 2018 without a material impact to the consolidated financial statements.

In January 2017, the FASB issued ASU 2017-04 to simplify the process used to test for goodwill impairment.  A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. This new guidance will be effective for the Company’s first quarter of 2020. The Company is currently evaluating the potential effect of this new guidance on its consolidated financial statements and related disclosures.

On May 10, 2017, the FASB issued ASU 2017-09, which amends the scope of modification accounting for share-based payment arrangements.  The ASU provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under ASC 718.  Specifically, an entity would not apply modification accounting if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification.  For all entities, the ASU is effective for annual reporting periods, including interim periods within those annual reporting periods, beginning after December 15, 2017.  The Company adopted this guidance on January 1, 2018 without a material impact to the consolidated financial statements.

Revenue Recognition [Abstract]

Revenue Recognition

B.  Revenue Recognition

The revenue streams in the discussion below and in the table on page 13 include those that are within the scope of ASU 2014-09.  Those revenues deemed out of scope and excluded are: investment gains and losses generated from the Company’s proprietary trading activities, dividend income, and interest income.  In all cases for all revenue streams discussed below, the revenue generated is from a single transaction price, and there is no need to allocate the amounts across more than a single revenue stream.  The customer for all revenues derived from open-end and closed-end funds described in detail below has been determined to be the fund itself and not the ultimate underlying investor in the fund.  The Company has identified similar performance obligations under ASU 2014-09 as compared with ASC Topic 605.  As a result, the timing of the recognition of our revenue remains the same under this new guidance as it was under ASC Topic 605.

Significant Judgments that affect the amounts and timing of revenue recognition:

The Company’s analysis of the timing of revenue recognition for each revenue stream is based upon an analysis of current contract terms.  Performance obligations could, however, change from time to time if and when existing contracts are modified or new contracts are entered into.  These changes could potentially affect the timing of satisfaction of performance obligations, the determination of the transaction price, and the allocation of the price to performance obligations.  In the case of the revenue streams discussed below, the performance obligation is satisfied at a point in time and in no instance is it satisfied over a period of time.  In the case of performance correlated revenues, the point in time is the end of the measurement period as defined within the contract and subject to reduction to zero on the date where the measurement period ends even if the performance benchmarks were exceeded during the intervening period.  Thus, for performance correlated revenues, the performance obligation is satisfied at a single point in time.  The judgments outlined below, where the determination as to these factors is discussed in detail, are continually reviewed and monitored by the Company when new contracts or contract modifications occur.  Transaction price is in all instances formulaic and not subject to significant (or any) judgment at the current time.  The allowance for doubtful accounts is subject to judgment.  There were no impairment losses (allowance for doubtful accounts) on any receivables from any revenue stream at the end of the current period.

Advisory Fee Revenues

Advisory fees for open-end funds, closed-end funds, sub-advisory accounts and SICAVs are earned based on predetermined percentages of the average net assets of the individual funds and are recognized as revenues as the related services are performed.  Fees for open-end funds, sub-advisory accounts and SICAVs are computed on a daily basis on average net assets under management ("AUM"), while fees for closed-end funds are computed on average weekly net AUM.  These fees are received in cash after the end of each monthly period within 30 days.  The revenue recognition occurs daily as the performance obligation (advising the fund) is met continuously.  There is a risk of non-payment, and therefore an impairment loss on these receivables is possible at each reporting date.  There were no such impairment losses for the current period.

Advisory fees for Institutional & Private Wealth Management accounts are earned based on predetermined percentages of the average AUM and are generally computed quarterly based on account values at the end of the preceding quarter.  The revenue recognition occurs daily as the performance obligation (advising the client portfolio) is met continuously.  These fees are received in cash, typically within 60 days of the client being billed.  There is a risk of non-payment, and therefore an impairment loss on these receivables is possible at each reporting date.  There were no such impairment losses for the current period.

Performance Correlated Revenues

Investment advisory fees earned on many of the closed-end funds' preferred shares are earned at year-end if the total return to common shareholders of the closed-end fund for the calendar year exceeds the dividend rate of the preferred shares.  These fees are recognized at the end of the measurement period which coincides with the calendar year.  The fee would also be earned and the contract period ended at any interim point in time that the preferred shares are redeemed.  These fees are received in cash after the end of the measurement period within 30 days.

Certain closed-end funds have performance fees that are earned at the end of the fund fiscal year to the extent the total return of each fund exceeds a benchmark return.  The fee would also be earned and the contract period ended at any interim point in time that the fund was to repurchase shares.  These fees are received in cash after the end of the measurement period within 30 days.

We also receive incentive fees from certain institutional clients which are based upon exceeding a specific benchmark index or indices.  These fees are recognized at the end of the stipulated contract period, which is generally annually, for the respective account.  The fee would also be earned and the contract period ended at any interim point in time that the client terminated its relationship with us.  These fees are received in cash after the end of the measurement period typically within 60 days.

Certain funds within the SICAV structure may charge a performance fee.  These fees are recognized at the end of the measurement period which coincides with the calendar year or upon redemption.  These fees are received in cash after the end of the measurement period within 30 days.

In all cases of the performance correlated revenue, revenue recognition is delayed until the performance obligation has been met (the measurement period has concluded and the hurdle has been exceeded).  There is a risk of non-payment, and therefore an impairment loss on these receivables is possible at each reporting date.  There were no such impairment losses for the current period.

Distribution Fees and Other Income

Distribution fees and other income primarily includes distribution fee revenue earned in accordance with Rule 12b-1 of the Company Act, as amended, along with sales charges and underwriting fees associated with the sale of the mutual funds.  Distribution plan fees are computed based on average daily net assets of each fund and are accrued for during the period in which they are earned.  These fees are received in cash after the end of each monthly period within 30 days.  In evaluating the appropriate timing of the recognition of these fees, we applied the guidance on up-front fees to determine whether such fees are related to the transfer of a promised service (a distinct performance obligation).  Our conclusion is that the service being provided by G.distributors to the customer in exchange for the fee is for the initial distribution of the funds and is completed at the time of the sale.  As such, there is no portion of this revenue that needs to be deferred because the performance obligation is complete, and revenue recognition coincides with the completion.  The Company reached the same conclusion with regard to sales charges and underwriting fees associated with the sale of the mutual funds - neither of which is material in the aggregate to the Company's revenue streams.  There is a risk of non-payment, and therefore an impairment loss on these receivables is possible at each reporting date.  There were no such impairment losses for the current period.

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 were classified as trading securities for the periods ended December 31, 2017 and March 31, 2017.  Securities carried at FVTNI for the March 31, 2018 period-end and trading securities in the periods ending December 31, 2017 and March 31, 2017 are stated at fair value, with any unrealized gains or losses reported in current period earnings.  Available for sale (“AFS”) investments for the periods ended December 31, 2017 and March 31, 2017 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 were recorded as realized losses in the condensed consolidated statements of income.

Effective January 1, 2018, the Company adopted ASU 2016-01, which eliminated available for sale accounting and resulted in the reclassification of $12.1 million, net of tax, out of accumulated comprehensive income and into retained earnings in the condensed consolidated statement of financial condition.  As a result, for the three months ended March 31, 2018, changes in the fair value of the Company’s entire investment portfolio are now recorded in the net gain (loss) from investments line in the condensed consolidated statements of income rather than through other comprehensive income.

The following table identifies all reclassifications out of accumulated other comprehensive income ("AOCI") into income for the three months ended March 31, 2017 (in thousands).  (No disclosure is needed for the three months ended March 31, 2018 due to the adoption of ASU 2016-01.)

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.  There were no sales of investments available for sale for the three months ended March 31, 2017.  There were no realized losses on the sale of investments available for sale for the three months ended March 31, 2017. The basis on which the cost of a security sold is determined using specific identification. Accumulated other comprehensive income in the condensed consolidated statements of equity is primarily comprised of unrealized gains/losses, net of taxes, for AFS securities.

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

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

The effective tax rate ("ETR") for the three months ended March 31, 2018 and March 31, 2017 was 22.6% and 38.1%, respectively.

The decline in the ETR is almost exclusively due to the lower Federal tax rate under the Tax Cuts and Jobs Act which lowered our Federal tax rate from 35% to 21%, effective January 1, 2018.

4.5% Convertible Note

On August 15, 2016, the Company issued and sold a 5-year, $110 million convertible note (“Convertible Note”).  The note bore interest at a rate of 4.5% per annum and was 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 was 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 was 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.  On November 20, 2017, the Company and the Convertible Note holder agreed to amend the Convertible Note to allow for an early redemption if the Company paid the Convertible Note holder 103% of the unpaid principal plus all accrued but unpaid interest on the redemption date.  On November 21, 2017, the Company redeemed the Convertible Note for $114.6 million.  The payment was equal to 103% of the unpaid principal amount of the note plus accrued interest.  As a result, the Company recorded a loss on extinguishment of debt of $3.3 million and expensed the remaining $135,000 of issuance costs.

GGCP, Inc. (“GGCP”), which owns approximately 63% of the equity interest of the Company, initially 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 (the “Escrow Agreement”).  In connection with the Initial Deposit made by GGCP, the Company had agreed that GGCP had a right to demand payment in an amount equal to any funds withdrawn from the escrow account by the Convertible Note holder.  On September 30, 2017, in connection with an amendment to the Escrow Agreement and in exchange for approximately 53% of the assets in the escrow account, the Company paid GGCP $60 million.  On November 21, 2017, the Company paid GGCP $53 million for the remaining 47% of the assets in the escrow account that it did not previously own.

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, 2018, the Company prepaid $10 million of principal of the AC 4% PIK Note against the principal amount due on November 30, 2020.  During the three months ended March 31, 2017, the Company prepaid $10 million of principal of the AC 4% PIK Note.

Subsequent to March 31, 2018, the Company paid an additional $10 million of principal, thereby reducing the amount outstanding to $30 million, all of which is due on November 30, 2020.

AC 1.6% Note

On December 26, 2017, to finance tax payments and for working capital purposes, the Company borrowed $15 million from AC in exchange for a note that bore interest at 1.6% per annum.  On February 28, 2018, the date of maturity, the Company repaid the entire principal and accrued interest.

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, 2018, December 31, 2017 and March 31, 2017, the debt was recorded at its face value, net of issuance costs, of $24.2 million, $24.1 million and $24.1 million, respectively.

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.  The Company has not elected the fair value option for its debt, and, therefore, the provisions of ASU 2016-01 (adopted by the Company on January 1, 2018) related to instrument-specific credit risk are not applicable.

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 one Plan approved by the shareholders, which is 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 7.5 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 December 31, 2017 and March 31, 2017, there were 19,400 RSA shares and 420,240 RSA shares outstanding, respectively, that were previously issued at an average weighted grant price of $65.67 and $65.59, respectively. These RSA grants occurred prior to the spin-off of Associated Capital (“AC”).  There were no RSAs outstanding as of March 31, 2018.  On November 30, 2015, pursuant to the spin-off, all RSA grant holders received shares of AC’s Class A common stock as a result of their ownership of their GAMCO unvested RSAs (one share of AC 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.

On January 5, 2018, the Compensation Committee of GBL accelerated the vesting relating to the remaining 19,400 RSAs outstanding.  As a result, GBL recorded an incremental $0.2 million of stock-based compensation expense during the first quarter of 2018.

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.  The Company’s accounting treatment for excess tax benefits or tax deficiencies also changed with the adoption of ASU 2016-09 on January 1, 2017. Excess tax benefits or tax deficiencies are now required to be recorded within the income tax expense line in the consolidated statement of income rather than to additional paid-in capital within the condensed consolidated statement of financial condition.  During the three months ended March 31, 2018, the Company reduced previously recorded tax benefits relating to RSA expense by $0.1 million on RSAs that vested.  There were no RSA vestings for the three months ended March 31, 2017.

For the three months ended March 31, 2018 and March 31, 2017, we recognized stock-based compensation expense of $0.2 million and $0.7 million, respectively. The three month amount for 2018 is entirely related to the GBL RSA accelerated vesting mentioned above.

As of March 31, 2018, there are no RSAs outstanding, and therefore there is no unrecognized stock compensation expense related to non-vested RSAs.

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, 2018, the Company repurchased 119,334 shares at an average price per share of $27.71.  From the inception of the program through March 31, 2018, 10,505,200 shares have been repurchased at an average price of $43.45 per share.  At March 31, 2018, the total shares available under the program to be repurchased in the future were 554,960.

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 expired in early May 2018.  As of March 31, 2018, $500 million is available on the shelf.  The Company filed a new shelf registration statement with the SEC in April 2018.

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, 2018.

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, 2017.

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 to receive 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.  In March 2016, the FASB issued revised guidance which clarifies the guidance related to (a) determining the appropriate unit of account under the revenue standard’s principal versus agent guidance and (b) applying the indicators of whether an entity is a principal or an agent in accordance with the revenue standard’s control principle. In April 2016, the FASB issued an amendment to provide more detailed guidance including additional implementation guidance and examples related to (a) identifying performance obligations and (b) licenses of intellectual property.  In May 2016, the FASB amended the standard to clarify the guidance on (a) assessing collectability, (b) presenting sales taxes, (c) measuring noncash consideration, and (d) certain transition matters.  The Company adopted this guidance on January 1, 2018 and adopted the modified retrospective approach.  The Company’s implementation analysis has been completed, and we have identified similar performance obligations under this guidance as compared with deliverables and separate units of account previously identified under Topic 605.  As a result, the timing of the recognition of our revenue remains the same as under Topic 605, and therefore the adoption does not have any effect on the timing of the recognition of revenue.  See Note B. Revenue Recognition for the disclosures required by ASU 2014-09.

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. In addition, the FASB clarified guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. To adopt the amendments, entities are 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 adopted this guidance on January 1, 2018 and reclassified $12.1 million out of Accumulated Other Comprehensive Income and into Retained Earnings.  Effective January 1, 2018, changes in the fair value of the Company’s investments in equity securities are reported through earnings in the net gain (loss) from investments line in the condensed consolidated statements of income rather than through other comprehensive income.

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. It requires these operating leases to be recorded on the balance sheet as right of use assets and offsetting lease liability obligations.  This new guidance will be effective for the Company’s first quarter of 2019. The Company is currently evaluating this guidance and the impact it will have on its consolidated financial statements and related disclosures.

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.  This guidance is intended to unify the currently diverse presentations and classifications, which address eight classification issues related to the statement of cash flows, including debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, distributions received from equity method investees, beneficial interests in securitization transactions, and separately identifiable cash flows and application of the predominance principle.  The Company adopted this guidance on January 1, 2018 without a material impact to the consolidated financial statements.

In January 2017, the FASB issued ASU 2017-04 to simplify the process used to test for goodwill impairment.  A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. This new guidance will be effective for the Company’s first quarter of 2020. The Company is currently evaluating the potential effect of this new guidance on its consolidated financial statements and related disclosures.

On May 10, 2017, the FASB issued ASU 2017-09, which amends the scope of modification accounting for share-based payment arrangements.  The ASU provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under ASC 718.  Specifically, an entity would not apply modification accounting if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification.  For all entities, the ASU is effective for annual reporting periods, including interim periods within those annual reporting periods, beginning after December 15, 2017.  The Company adopted this guidance on January 1, 2018 without a material impact to the consolidated financial statements.
