MDC PARTNERS INC. AND SUBSIDIARIES
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(thousands of United States dollars, except per share amounts, unless otherwise stated)
1. Basis of Presentation and Recent Developments
The accompanying consolidated financial statements include the accounts of MDC Partners Inc. (the “Company” or “MDC”), its subsidiaries and variable interest entities for which the Company is the primary beneficiary. References herein to “Partner Firms” generally refer to the Company’s subsidiary agencies.
MDC Partners Inc. has prepared the unaudited condensed consolidated interim financial statements included herein in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for reporting interim financial information on Form 10-Q. Accordingly, the financial statements have been condensed and do not include certain information and disclosures pursuant to these rules. The preparation of financial statements in conformity with GAAP requires us to make judgments, assumptions and estimates that affect the amounts reported and disclosed. Actual results could differ from these estimates and assumptions. The consolidated results for interim periods are not necessarily indicative of results for the full year and should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 20172018 (“20172018 Form 10-K”).
The accompanying financial statements reflect all adjustments, consisting of normally recurring accruals, which in the opinion of management are necessary for a fair presentation, in all material respects, of the information contained therein. Intercompany balances and transactions have been eliminated in consolidation.
Certain reclassifications have been made to the prior year financial information to conform to the current year presentation, such aspresentation.
Due to changes in the composition of certain business and the Company’s internal management and reporting structure during 2019, reportable segment results for the 2018 periods presented have been recast to reflect the reclassification of contingent consideration payments in the statement of cash flows in connection with the adoption of Accounting Standards Update (“ASU”) 2016-15, Statement of Cash Flow.certain businesses between segments. See Note 14 of the Notes to the Unaudited Condensed Consolidated Financial Statements for additional information regarding the new guidance and reclass within the statement of cash flows.
On September 12 2018 the Company announced that Scott Kauffman will step down as the Company’s Chairman and Chief Executive Officer. He will remain in his role as Chairman and CEO until a successor is named. Mr. Kauffman is also expected to continue as a member of the MDC Board of Directors for the remainder of his current term.

On September 20, 2018, the Company announced its intention to explore and evaluate potential strategic alternatives, which may result in, among other things, the possible sale of the Company. The Company has not made a decision to pursue any specific strategic alternative, and there is no timetable for completing the strategic review process. This review process is proceeding in parallel with the Company’s search to identify a successor CEO. There can be no assurance that the Company will complete any specific action or transaction.

2. Revenue
Effective January 1, 2018, the Company adopted Financial Accounting Standards Board (the “FASB”) ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”). ASC 606 was applied using the modified retrospective method, with the cumulative effect of the initial adoption being recognized as an adjustment to opening retained earnings at January 1, 2018. As a result, comparative prior periods have not been adjusted and continue to be reported under FASB ASC Topic 605, Revenue Recognition (“ASC 605”). See Note 14 of the Notes to the Unaudited Condensed Consolidated Financial Statements included herein for additional details surrounding the Company’s adoption of ASC 606. The Company’s policy surrounding revenue under ASC 605 is described in Note 2 of Item 8 of the Company’s 2017 Form 10-K. The policies described herein refer to those in effect as of January 1, 2018.further information.
2. Revenue
The Company’s revenue recognition policies are established in accordance with the Revenue Recognition topics of ASC 606, and accordingly, revenue is recognized when control of the promised goods or services is transferred to our clients, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services.
The MDC network provides an extensive range of services to our clients offering a variety of marketing and communication capabilities including strategy, creative and production for advertising campaigns across a variety of platforms (print, digital, social media, television broadcast), public relations services including strategy, editorial, crisis support or issues management, media training, influencer engagement and events management. We also provide media buying and planning across a range of platforms (out-of-home, paid search, social media, lead generation, programmatic, television broadcast), experiential marketing and application/website design and development.
The primary source of the Company’s revenue is from agency arrangements in the form of fees for services performed, commissions, and from performance incentives or bonuses, depending on the terms of the client contract. In all circumstances, revenue is only recognized when collection is reasonably assured. Certain of the Company’s contractual arrangements have more than one performance obligation. For such arrangements, revenue is allocated to each performance obligation based on its relative stand-alone selling price. Stand-alone selling prices are determined based on the prices charged to clients or using expected cost plus margin.
The determination of our performance obligations is specific to the services included within each contract. Based on a client’s requirements within the contract, and how these services are provided, multiple services could represent separate performance obligations or be combined and considered one performance obligation. Contracts that contain services that are not significantly integrated nor interdependent, nor that significantly modify or customize each other, are considered separate performance obligations. Typically, we consider media planning, media buying, creative (or strategy), production and experiential marketing services to be separate performance obligations if included in the same contract as each of these services can be provided on a stand-alone basis, and do not significantly modify or customize each other. Public relations services and application/website design and development are typically each considered one performance obligation as there is a significant integration of these services into a combined output.
We typically satisfy our performance obligations over time, as services are performed. Fees for services are typically recognized using input methods (direct labor hours, materials and third-party costs) that correspond with efforts incurred to date in relation to total estimated efforts to complete the contract. Point in time recognition primarily relates to certain commission-based contracts, which are recognized upon the placement of advertisements in various media when the Company has no further performance obligation.                                            

Revenue is recognized net of sales and other taxes due to be collected and remitted to governmental authorities. The Company’s contracts typically provide for termination by either party within 30 to 90 days. Although payment terms vary by client, they are

typically within 30 to 60 days. In addition, the Company generally has the right to payment for all services provided through the end of the contract or termination date.
Although certain of our performance obligations are recognized at a point in time, we typically satisfy our performance obligations over time, as services are performed. Point in time recognition primarily relates to certain commission-based contracts, which are recognized upon the placement of advertisements in various media when the Company has no further performance obligation. Fees for services are typically recognized using input methods that correspond with efforts incurred to date in relation to total estimated efforts to complete the contract.
Within each contract, we identify whether the Company is principal or agent at the performance obligation level. In arrangements where the Company has substantive control over the service before transferring it to the client, and is primarily responsible for integrating the services into the final deliverables, we act as principal. In these arrangements, revenue is recorded at the gross amount billed. Accordingly, for these contracts the Company has included reimbursed expenses in revenue. In other arrangements where a third-party supplier, rather than the Company is primarily responsible for the integration of services into the final deliverables, and thus the Company is solely arranging for the third-party supplier to provide these services to our client, then we generally act as agent and record revenue equal to the net amount retained, when the fee or commission is earned. The role of MDC’s agencies under a production services agreement is to facilitate a client’s purchasing of production capabilities from a third-party production company in accordance with the client’s strategy and guidelines. The obligation of MDC’s agencies under media buying services is to negotiate and purchase advertising media from a third-party media vendor on behalf of a client to execute its media plan. We have determined thatdo not obtain control prior to transferring these services to our clients; therefore, we primarily act as agent for production and media buying services.
A small portion of the Company’s contractual arrangements with clients include performance incentive provisions, which allow the Company to earn additional revenues as a result of its performance relative to both quantitative and qualitative goals. Incentive compensation is primarily estimated using the most likely amount method and is included in revenue up to the amount that is not expected to result in a reversal of a significant amount of cumulative revenue recognized. We recognize revenue related to performance incentives as we satisfy the performance obligation to which the performance incentives are related.

Disaggregated Revenue Data
The Company provides a broad range of services to a large base of clients across the full spectrum of industry verticals on a global basis. The primary source of revenue is from agency arrangements in the form of fees for services performed, commissions, and from performance incentives or bonuses. Certain clients may engage with the Company in various geographic locations, across multiple disciplines, and through multiple Partner Firms. Representation of a client rarely means that MDC handles marketing communications for all brands or product lines of the client in every geographical location. The Company’s Partner firms often cooperate with one another through referrals and the sharing of both services and expertise, which enables MDC to service clients’ varied marketing needs by crafting custom integrated solutions. Additionally, the Company maintains separate, independent operating companies to enable it to effectively manage potential conflicts of interest by representing competing clients across the MDC network.
The following table presents revenue disaggregated by client industry vertical for the three and ninesix months ended SeptemberJune 30, 20182019 and 2017, and the impact of adoption of ASC 606:2018:

Today, MDC’s Partner Firms are located in the United States, Canada, and an additional thirteentwelve countries around the world. In the past, some clients have responded to weakening economic conditions with reductions to their marketing budgets, which included discretionary components that are easier to reduce in the short term than other operating expenses.

Contract assets and liabilities
Contract assets consist of fees and reimbursable outside vendor costs incurred on behalf of clients when providing advertising, marketing and corporate communications services that have not yet been invoiced to clients. Unbilled service fees were $92,900$92,317 and $54,177$64,362 at SeptemberJune 30, 20182019 and December 31, 2017,2018, respectively, and are included as a component of accounts receivable on the unaudited condensed consolidated balance sheets.Unaudited Condensed Consolidated Balance Sheets. Outside vendor costs incurred on behalf of clients which have yet to be invoiced were $59,317$40,605 and $31,146$42,369 at SeptemberJune 30, 20182019 and December 31, 2017,2018, respectively, and are included on the unaudited condensed consolidated balance sheetsUnaudited Condensed Consolidated Balance Sheets as expenditures billable to clients. Such amounts are invoiced to clients at various times over the course of the production process.providing services.
Contract liabilities consist of fees billed to clients in excess of fees recognized as revenue and are classified as advance billings on the Company’s unaudited condensed consolidated balance sheets.Unaudited Condensed Consolidated Balance Sheets. Advance billings at SeptemberJune 30, 20182019 and December 31, 20172018 were $182,305$168,142 and $148,133,$138,505, respectively. The increase in the advance billings balance of $34,172$29,637 for the ninesix months ended SeptemberJune 30, 20182019 is primarily driven by cash payments received or due in advance of satisfying our performance obligations, offset by $85,665$101,431 of revenues recognized that were included in the advance billings balances as of December 31, 20172018 and reductions due to the incurrence of third-party costs.
Changes in the contract asset and liability balances during the ninesix months ended SeptemberJune 30, 20182019 and December 31, 20172018 were not materially impacted by write offs,write-offs, impairment losses or any other factors.
Practical expedients
In adopting ASC 606, the Company applied the practical expedient to not disclose information about remaining performance obligations that have original expected durations of one year or less. Amounts related to those performance obligations with expected durations of more than one year are immaterial.

6. Leases

Effective January 1, 2019, the Company adopted FASB ASC Topic 842, Leases (“ASC 842”). As a result, comparative prior periods have not been adjusted and continue to be reported under FASB ASC Topic 840, Leases. See Note 14 of the Notes to the Unaudited Condensed Consolidated Financial Statements included herein for additional information regarding the Company’s adoption of ASC 842. The policies described herein refer to those in effect as of January 1, 2019.
The Company leases office space in North America, Europe, Asia, South America, and Australia. This space is primarily used for office and administrative purposes by the Company’s employees in performing professional services. These leases are classified as operating leases and expire between years 2019 through 2032. Finance leases are considered to be immaterial to the Company.
The Company’s leasing policies are established in accordance with ASC 842, and accordingly, the Company recognizes on the balance sheet at the time of lease commencement a right-of-use asset and a lease liability, initially measured at the present value of the lease payments. Right-of-use lease assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. All right-of-use assets are reviewed for impairment. As the Company’s implicit rate in its leases is not readily determinable, in determining the present value of lease payments, the Company uses its incremental borrowing rate based on the information available at the commencement date. Lease payments included in the measurement of the lease liability are comprised of noncancelable lease payments, payments based upon an index or rate, payments for optional renewal periods where it is reasonably certain the renewal period will be exercised, and payments for early termination options unless it is reasonably certain the lease will not be terminated early.
Lease costs are recognized in the Consolidated Statement of Operations over the lease term on a straight-line basis. Leasehold improvements are depreciated on a straight-line basis over the lesser of the term of the related lease or the estimated useful life of the asset. 
Some of the Company’s leases contain variable lease payments, including payments based upon an index or rate. Variable lease payments based upon an index or rate are initially measured using the index or rate in effect at the lease commencement date and are included within the lease liabilities. Lease liabilities are not remeasured as a result of changes in the index or rate, rather changes in these types of payments are recognized in the period in which the obligation for those payments is incurred. In addition, some of our leases contain variable payments for utilities, insurance, real estate tax, repairs and maintenance, and other variable operating expenses. Such amounts are not included in the measurement of the lease liability and are recognized in the period when the facts and circumstances on which the variable lease payments are based upon occur.
The Company’s leases include options to extend or renew the lease through 2040. The renewal and extension options are not included in the lease term as the Company is not reasonably certain that it will exercise its option.
From time to time, the Company enters into sublease arrangements both with unrelated third-parties and with our partner agencies. These leases are classified as operating leases and expire between years 2019 through 2023. Sublease income is recognized over the lease term on a straight-line basis. Currently, the Company subleases office space in North America, Europe and Asia.
As of June 30, 2019, the Company has entered into an operating lease for which the commencement date has not yet occurred as this leased space is in the process of being prepared by the landlord for occupancy. Accordingly, this lease represents an obligation of the Company that is not on the Consolidated Balance Sheet as of June 30, 2019. The aggregate future liability related to the lease is approximately $6 million.
The discount rate used for leases accounted for under ASC 842 is the Company’s collateralized credit adjusted borrowing rate.

The following table presents lease costs and other quantitative information for the three and six months ended June 30, 2019:

 Three Months Ended June 30, Six Months Ended June 30,

Operating lease expense is included in office and general expenses in the Unaudited Condensed Consolidated Statement of Operations. Lease expense for leases with a term of 12 months or less is immaterial to the Company. Rental expense for the three and six months ended June 30, 2018 was $15,981 and $33,541, respectively, offset by $926 and $1,640, respectively in sublease rental income.

6.50% Notes
On March 23, 2016, MDC entered into an indenture (the “Indenture”) among MDC, its existing and future restricted subsidiaries that guarantee, are co-borrowers under, or grant liens to secure, the Credit Agreement, as guarantors (the “Guarantors”) and The Bank of New York Mellon, as trustee, relating to the issuance by MDC of $900,000 aggregate principal amount of the senior unsecured notes due 2024 (the “6.50% Notes”) . The 6.50% Notes were sold in a private placement in reliance on exceptions from registration under the Securities Act of 1933. The 6.50% Notes bear interest, payable semiannually in arrears on May 1 and November 1, at a rate of 6.50% per annum. The 6.50% Notes mature on May 1, 2024, unless earlier redeemed or repurchased.

MDC may, at its option, redeem the 6.50% Notes in whole at any time or in part from time to time, on and after May 1, 2019, at varying prices based on the timing of the redemption.
If MDC experiences certain kinds of changes of control (as defined in the Indenture), holders of the 6.50% Notes may require MDC to repurchase any 6.50% Notes held by them at a price equal to 101% of the principal amount of the 6.50% Notes plus accrued and unpaid interest. In addition, if MDC sells assets under certain circumstances, it must apply the proceeds from such sale and offer to repurchase the 6.50% Notes at a price equal to 100% of the principal amount plus accrued and unpaid interest.
The Indenture includes covenants that are subject to a number of important limitations and exceptions. The 6.50% Notes are also subject to customary events of default, including a cross-payment default and cross-acceleration provision. The Company was in compliance with all covenants at SeptemberJune 30, 2018.2019.

8.9. Noncontrolling and Redeemable Noncontrolling Interests
When acquiring less than 100% ownership of an entity, the Company may enter into agreements that give the Company an option to purchase, or require the Company to purchase, the incremental ownership interests under certain circumstances. Where the option to purchase the incremental ownership is within the Company’s control, the amounts are recorded as noncontrolling

interests in the equity section of the Company’s balance sheet.Unaudited Condensed Consolidated Balance Sheets. Where the incremental purchase may be required of the Company, the amounts are recorded as redeemable noncontrolling interests in mezzanine equity at their estimated acquisition date redemption value and adjusted at each reporting period for changes to their estimated redemption value through additional paid-in capital (but not less than their initial redemption value), except for foreign currency translation adjustments. On occasion, the Company may initiate a renegotiation to acquire an incremental ownership interest and the amount of consideration paid may differ materially from the balance sheet amounts.amounts recorded in the Company’s Unaudited Condensed Consolidated Balance Sheets.

The noncontrolling shareholders’ ability to exercise any such option right is subject to the satisfaction of certain conditions, including conditions requiring notice in advance of exercise and specific employment termination conditions. In addition, these rights cannot be exercised prior to specified staggered exercise dates. The exercise of these rights at their earliest contractual date

would result in obligations of the Company to fund the related amounts during 20182019 to 2023.2024. It is not determinable, at this time, if or when the owners of these rights will exercise all or a portion of these rights.
The amount payable by the Company to purchase the noncontrolling shareholders’ incremental ownership interests if exercised is dependent on various valuation formulas and on future events, such as the average earnings of the relevant subsidiary through the date of exercise, the growth rate of the earnings of the relevant subsidiary during that period and, in some cases, the currency exchange rate at the date of payment. The ultimate amount payable relating to these transactions will vary because it is dependent on the future results of operations of the subject businesses and the timing of when these rights are exercised.
The redeemable noncontrolling interest of $57,193$42,635 as of SeptemberJune 30, 2018,2019, consists of $14,320$19,158 assuming that the subsidiaries perform over the relevant future periods at their discounted cash flows earnings level and such rights are exercised, $38,540$19,926 upon termination of such owner’s employment with the applicable subsidiary or death and $4,333$3,551 representing the initial redemption

value (required floor) recorded for certain acquisitions in excess of the amount the Company would have to pay should the Company acquire the remaining ownership interests for such subsidiaries.
These adjustments will not impact the calculation of earnings (loss) per share if the redemption values are less than the estimated fair values. For the ninethree months ended SeptemberJune 30, 20182019 and 2017,2018, there was no related impact on the Company’s loss per share calculation.  
9. Convertible Preference Shares
On March 7, 2017 (the “Issue Date”), the Company issued 95,000 newly created Preference Shares to affiliates of The Goldman Sachs Group, Inc. (collectively, the “Purchaser”) pursuant to a $95,000 private placement. The Company received proceeds of approximately $90,123, net of fees and estimated expenses, which were primarily used to pay down existing debt under the Company’s credit facility and for general corporate purposes. In connection with the closing of the transaction, effective March 7, 2017, the Company increased the size of its Board of Directors (the “Board”) to seven members and appointed one nominee designated by the Purchaser. Except as required by law, the Preference Shares do not have voting rights, and are not redeemable at the option of the Purchaser.
The holders of the Preference Shares have the right to convert their Preference Shares in whole at any time and from time to time, and in part at any time and from time to time after the ninetieth day following the original issuance date of the Preference Shares, into a number of Class A Shares equal to the then-applicable liquidation preference divided by the applicable conversion price at such time (the “Conversion Price”). The initial liquidation per share preference of each Preference Share is $1,000. The initial Conversion Price will be $10.00 per Preference Share, subject to customary adjustments for share splits and combinations, dividends, recapitalizations and other matters, including weighted average anti-dilution protection for certain issuances of equity or equity-linked securities.
The Preference Shares’ liquidation preference accretes at 8.0% per annum, compounded quarterly until the five-year anniversary of the Issue Date. During the nine months ended September 30, 2018, the Preference Shares accreted at a monthly rate of approximately $7.40 per Preference Share, for total accretion of $6,204, bringing the aggregate liquidation preference to $107,556 as of September 30, 2018. The accretion is considered in the calculation of net income (loss) attributable to MDC Partners Inc. common shareholders. See Note 3 of the Notes to the Unaudited Condensed Consolidated Financial Statements included herein for further information.
Holders of the Preference Shares are entitled to dividends in an amount equal to any dividends that would otherwise have been payable on the Class A Shares issued upon conversion of the Preference Shares. The Preference Shares are convertible at the Company’s option (i) on and after the two-year anniversary of the Issue Date, if the closing trading price of the Class A Shares over a specified period prior to conversion is at least 125% of the Conversion Price or (ii) after the fifth anniversary of the Issue Date, if the closing trading price of the Class A Shares over a specified period prior to conversion is at least equal to the Conversion Price.
Following certain change in control transactions of the Company in which holders of Preference Shares are not entitled to receive cash or qualifying listed securities with a value at least equal to the liquidation preference plus accrued and unpaid dividends, (i) holders will be entitled to cash dividends on the liquidation preference at an increasing rate (beginning at 7%), and (ii) the Company will have a right to redeem the Preference Shares for cash at the greater of their liquidation preference plus accrued and unpaid dividends or their as-converted value.

10. Fair Value Measurements
A fair value measurement assumes a transaction to sell an asset or transfer a liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability.
In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as considers counterparty credit risk in its assessment of fair value. The hierarchy for observable and unobservable inputs used to measure fair value into three broad levels are described below: 
Level 1 - Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs.
Level 2 - Observable prices that are based on inputs not quoted on active markets, but corroborated by market data.
Level 3 - Unobservable inputs are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs.
Financial Liabilities that are not Measured at Fair Value on a Recurring Basis
The following table presents certain information for our financial liability that is not measured at fair value on a recurring basis at SeptemberJune 30, 20182019 and December 31, 2017:2018:

Financial Liabilities Measured at Fair Value on a Recurring Basis
Contingent deferred acquisition consideration are recorded at the acquisition date fair value and adjusted at each reporting period. The estimated liability is determined in accordance with various contractual valuation formulas that may be dependent onupon future events, such as the growth rate of the earnings of the relevant subsidiary during the contractual period and, in some cases, the currency exchange rate as of the date of payment (Level 3). See Note 5 of the Notes to the Unaudited Condensed Consolidated Financial Statements included herein for additional information regarding contingent deferred acquisition consideration.
At SeptemberJune 30, 20182019 and December 31, 2017,2018, the carrying amount of the Company’s financial instruments, including cash and cash equivalents, accounts receivable and accounts payable, approximated fair value because of their short-term maturity. The Company does not disclose the fair value for equity method investments or investments held at cost as it is not practical to estimate fair value since there is no readily available market data.
Non-financial Assets and Liabilities that are Measured at Fair Value on a Nonrecurring Basis
Certain non-financial assets are measured at fair value on a nonrecurring basis, primarily goodwill and intangible assets and property and equipment.(a Level 3 fair value assessment). Accordingly, these assets are not measured and adjusted to fair value on an ongoing basis but are subject to periodic evaluations for potential impairment. During the third quarter of 2018, theThe Company performed an interim goodwill impairment evaluation resulting indid not recognize an impairment of goodwill.

11. Supplemental Information
Accounts Payable, Accruals and Other Liabilities
At SeptemberJune 30, 20182019 and December 31, 2017, accounts payable included $54,320 and $41,989 of outstanding checks, respectively.
At September 30, 2018, and December 31, 2017, accruals and other liabilities included accrued media of $173,222$151,143 and $207,482,$180,586, respectively; and also includeincluded amounts due to noncontrolling interest holders for their share of profits. See Note 89 of the Notes to the Unaudited Condensed Consolidated Financial Statements included herein for additional information regarding noncontrolling interest holders share of profits.

Goodwill and Other Asset ImpairmentIndefinite Lived Intangibles
The Company recognized an impairment of goodwillGoodwill and otherindefinite life intangible assets of $21,008 in the three months ended and $23,325 for the nine months ended September 30, 2018. The impairment primarily consists of the write-down of goodwill equal to the excess

carrying value above the fair value(trademarks) acquired as a result of a business combination which are not subject to amortization are tested for impairment annually as of October 1st of each year, or more frequently if indicators of potential impairment exist. For goodwill, impairment is assessed at the reporting unit within the Global Integrated Agencies reportable segmentlevel. Goodwill balances as of June 30, 2019 and the full write-down of a trademark for a reporting unit also within the Global Integrated Agencies reportable segment. The trademark is no longer in active use given its merger with another reporting unit in the third quarter of 2018. See Note 12 of the Notes to the Unaudited Condensed Consolidated Financial Statements for information related to the merger.

During the third quarter ofDecember 31, 2018, the Company performed an interim goodwill impairment test resulting in, along with the impairment mentioned above, the fair value of a reporting unit, with goodwill of approximately $130,000, exceeding its carrying value by a minimal percentage. A reduction in the projected long-term operating performance of this reporting unit, market declines, changes in discount rates or other conditions could result in an impairment in the future. In connection with the interim impairment test, the Company used a combination of the income approach, which incorporates the use of a discounted cash flow method,were $743,582 and the market approach, which incorporates the use of earnings and revenue multiples based on market data. The Company applied an equal weighting to the income and market approaches for the impairment test. The income approach and the market approach both require the exercise of significant judgment, including judgment about the amount and timing of expected future cash flows, assumed terminal value and appropriate discount rates. This methodology is a Level 3 fair value assessment.$740,955, respectively.

Income Taxes

Our tax provision for interim periods is determined using an estimated annual effective tax rate, adjusted for discrete items arising in the quarter. Our 2018 estimated annual effective tax rate of 26.3% differs from the Canadian statutory rate of 26.5% primarily due to exclusion of income attributable to minority interest from the annual forecasted income, partially offset by U.S. federal tax impact of Global Intangible Low Taxed Income (GILTI) inclusion as well as certain non-deductible expenditures.
On December 22, 2017, the 2017 Tax Cuts and Jobs Act (the “Tax Act”) was enacted into law and the new legislation contains several key tax provisions, including a reduction of the U.S. corporate income tax rate to 21% effective January 1, 2018. The Company is required to recognize the effect of tax law changes in the period of enactment, which required the Company to re-measure its U.S. deferred tax assets and liabilities and to reassess the net realizability of its deferred tax assets and liabilities. In December 2017, the SEC staff issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”), which allows the Company to record provisional amounts during a measurement period not to extend beyond one year from the enactment date. The Company recorded a provisional tax expense of $26,674 at year-end related to re-measurement of deferred tax assets and liabilities due to change in corporate tax rate from 35% to 21%. The Company recorded no tax expense related to transition tax.
The Act created a new requirement that Global Intangible Low-Taxed Income (i.e., GILTI) earned by controlled foreign corporations (CFCs) must be included currently in the gross income of the CFCs’ U.S. shareholder. GILTI is the excess of the shareholder’s “net CFC tested income” over the net deemed tangible income return (the “routine return”), which is defined as the excess of (1) 10% of the aggregate of the U.S. shareholder’s pro rata share of the qualified business asset investment (QBAI) of each CFC with respect to which it is a U.S. shareholder over (2) the amount of certain interest expense taken into account in the determination of net CFC-tested income. A deduction is permitted to a domestic corporation in an amount up to 50% of the sum of the GILTI inclusion and the amount treated as a dividend because the corporation has claimed a foreign tax credit (FTC) as a result of the inclusion of the GILTI amount in income.
During the quarter ended September 30, 2018, the Company evaluated additional guidance provided by the tax authorities and has completed its tax accounting for the provisions of the Act in accordance with SAB 118. The Company has not recorded an adjustment to its provisional estimate during the period ended September 30, 2018 and has made a policy election to record tax effects of GILTI as a period expense when incurred.
The Company has unrecognized tax benefits at September 30, 2018 of $1,198, as compared to $1,556 at December 31, 2017. It is reasonably possible that the amount of unrecognized tax benefits could decrease by a range of $400 to $500 within the next twelve months as a result of expiration of certain statute of limitations.interim periods.
Income tax expense for the three months ended SeptemberJune 30, 20182019 was $2,986$2,088 (on a lossincome of $10,981$9,215 resulting in an effective tax rate of 27.1%22.7%) compared to $9,049an expense of $1,977 (on income of $29,611$7,956 resulting in an effective tax rate of 30.6%24.8%) for the three months ended SeptemberJune 30, 2017, representing a decrease of $6,063.2018. The variancechange in the effective tax expense year over yearrate was primarily driven by impairments and non-deductible stock compensation in the current period for which tax benefit was not recognized as well as the impactjurisdictional mix of a valuation allowance in the U.S. in the prior period.earnings.  
Our effective tax rate for the nine months ended September 30, 2018 was 8.4% compared to 42.5% for the nine months ended September 30, 2017. Income tax expense for the ninesix months ended SeptemberJune 30, 20182019 was $2,835 (on income of $10,195 resulting in an effective tax rate of 27.8%) compared to a benefit of $3,367 compared to$6,353 (on a loss of $28,979 resulting in an expenseeffective tax rate of $17,65921.9%) for the ninesix months ended SeptemberJune 30, 2017, representing a decrease of $21,026.2018. The variancechange in the effective tax expense year over yearrate was primarily driven by the jurisdictional mix of earnings, non-deductible impairments and stock compensation in the current period for which tax benefit was not recognized as well as the impact of a valuation allowance in the U.S. in the prior period.earnings.

12. Segment Information
The Company determines an operating segment if a component (i) engages in business activities from which it earns revenues and incurs expenses, (ii) has discrete financial information, and is (iii) regularly reviewed by the Chief Operating Decision Maker (“CODM”) to make decisions regarding resource allocation for the segment and assess its performance. Once operating segments are identified, the Company performs an analysis to determine if aggregation of operating segments is applicable. This determination is based upon a quantitative analysis of the expected and historic average long-term profitability for each operating segment, together with a qualitative assessment to determine if operating segments have similar operating characteristics.
Due to changes in the composition of certain business and the Company’s internal management and reporting structure during 2018,2019, reportable segment results for the 20172018 periods presented have been recast to reflect the reclassification of certain businesses between segments. The changes were as follows:
Source Marketing,Doner, previously within the All Other category, was included within the Doner operating segment, which is aggregated into the Global Integrated Agencies reportable segment
Yamamoto, previously within the All Other category, was operationally merged with Civilian and is now included within the Domestic Creative Agencies reportable segmentsegment.
Bruce Mau Design, Hello DesignHL Group Partners, previously within the Specialist Communications reportable segment, and Northstar Research Partners,Redscout, previously within the All Other category, and Varick Media Management,are now included in the Yes & Company operating segment. The Yes & Company operating segment previously within the Media Services reportable segment wereis now included into a newly-formedwithin the Domestic Creative Agencies reportable segment.
Attention, previously within the Forsman & Bodenfors operating segment Yes & Company,has operationally merged into MDC Media Partners, which is aggregatedincluded within the Media Services reportable segment

See Note 2 of the Notes to the Unaudited Condensed Consolidated Financial Statements included herein for a summary of the Company’s revenue by geographic region for three and nine months ended SeptemberJune 30, 20182019 and 2017.2018.

13. Commitments, Contingencies, and Guarantees
Legal Proceedings. The Company’s operating entities are involved in legal proceedings of various types. While any litigation contains an element of uncertainty, the Company has no reason to believe that the outcome of such proceedings or claims will have a material adverse effect on the financial condition or results of operations of the Company.
Dismissal of Class Action Litigation in Canada. On August 7, 2015, Roberto Paniccia issued a Statement of Claim in the Ontario Superior Court of Justice in the City of Brantford, Ontario seeking to certify a class action suit naming the following as defendants: MDC, former CEO Miles S. Nadal, former CAO Michael C. Sabatino, CFO David Doft and BDO U.S.A. LLP. The Plaintiff alleged violations of section 138.1 of the Ontario Securities Act (and equivalent legislation in other Canadian provinces and territories) as well as common law misrepresentation based on allegedly materially false and misleading statements in the Company’s public statements, as well as omitting to disclose material facts with respect to the SEC investigation. On June 4, 2018, the Court dismissed (with costs) the putative class members’ motion for leave to proceed with the Plaintiff’s claims for misrepresentations of material facts pursuant to the Ontario Securities Act. Following the Court’s decision, on June 18, 2018, the Plaintiff, MDC and each of the other defendants consented to the dismissal of the action with prejudice (and without costs). In July 2018, the Court entered a final order approving the dismissal of this claim.
Antitrust Subpoena. In 2016, one of the Company’s subsidiary agencies received a subpoena from the U.S. Department of Justice Antitrust Division (the “DOJ”) concerning the DOJ’s ongoing investigation of production bidding practices in the advertising industry. The Company and its subsidiary are fully cooperating with this confidential investigation. Specifically, the Company

and its subsidiary are providing information and engaging in discussions with the DOJ, including preliminary discussions regarding the feasibility of a potential settlement with the DOJ. However, there can be no assurance as to the timing of any settlement or that a settlement will be reached on any particular terms or at all. Moreover, the DOJ may determine to expand the scope of its investigation or initiate a proceeding to bring charges against our subsidiary or one or more members of the subsidiary agency’s former management. The DOJ may also seek to impose monetary sanctions.
Deferred Acquisition Consideration and Options to Purchase. See NoteNotes 5 and 89 of the Notes to the Unaudited Condensed Consolidated Financial Statements included herein for information regarding potential payments associated with deferred acquisition consideration and the acquisition of noncontrolling shareholders’ ownership interest in subsidiaries.
Natural Disasters. Certain of the Company’s operations are located in regions of the United States which typically are subject to hurricanes. During the ninethree and six months ended SeptemberJune 30, 20182019 and 2017,2018 these operations did not incur any material costs related to damages resulting from hurricanes.
Guarantees. Generally, the Company has indemnified the purchasers of certain assets in the event that a third party asserts a claim against the purchaser that relates to a liability retained by the Company. These types of indemnification guarantees typically

extend for a number of years. Historically, the Company has not made any significant indemnification payments under such agreements and no amount has been accrued in the accompanying consolidated financial statements with respect to these indemnification guarantees. The Company continues to monitor the conditions that are subject to guarantees and indemnifications to identify whether it is probable that a loss has occurred and would recognize any such losses under any guarantees or indemnifications in the period when those losses are probable and estimable.
Commitments.  At SeptemberJune 30, 2018,2019, the Company had $5,248$4,744 of undrawn letters of credit. In addition, the Company has commitments to fund investments in an aggregate amount of $60.

14. New Accounting Pronouncements
Adopted In The Current Reporting Period
Effective January 1, 2018,2019, the Company adopted FASB ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”). ASC 606 was applied using the modified retrospective method, with the cumulative effect of the initial adoption being recognized as an adjustment to opening retained earnings at January 1, 2018.842. As a result, comparative prior periods have not been adjusted and continue to be reported under FASB ASC Topic 605, Revenue Recognition (“ASC 605”).
The following represents changes to the Company’s policies resulting from840, Leases. With the adoption of ASC 606:
i.Under the guidance in effect through December 31, 2017, performance incentives were recognized in revenue when specific quantitative goals were achieved, or when the Company’s performance against qualitative goals was determined by the client. Under ASC 606, the Company now estimates the amount of the incentive that will be earned at the inception of the contract and recognizes such incentive over the term of the contract. This results in an acceleration of revenue recognition for certain contract incentives compared to ASC 605.
ii.Under the guidance in effect through December 31, 2017, non-refundable retainer fees were generally recognized on a straight-line basis over the term of the specific customer arrangement. Under ASC 606, an input method is typically used to measure progress and recognize revenue for these types of arrangements. This resulted in both the deferral and acceleration of revenue recognition in certain instances.
iii.In certain client arrangements, the Company records revenue as a principal and includes within revenue certain third-party-pass-through and out-of-pocket costs, which are billed to clients in connection with the services provided. In other arrangements, the Company acts as an agent and records revenue equal to the net amount retained. The adoption of ASC 606 resulted in certain arrangements previously being accounted for as principal, now being accounted for as agent.
As a result of these changes,842, the Company recordedhas elected to apply the package of practical expedients: (1) whether a cumulative effect adjustmentcontract is or contains a lease, (2) the classification of existing leases, and (3) whether previously capitalized costs continue to increase opening accumulated deficit at January 1, 2018 by $1,170.qualify as initial indirect costs. Additionally, the Company elected the practical expedient to not separate non-lease components from lease components for all operating leases.
The following table summarizes the impact of adoption of ASC 606 on the unaudited condensed consolidated statement of operations during the three and nine months ended September 30, 2018:

The impact on the balance sheets and shareholders’ deficit as of and for the nine months ended September 30, 2018 was immaterial. There was no effect on other comprehensive income (loss) and the statement of cash flows for the three and nine months ended September 30, 2018 and 2017.
In May 2017, the FASB issued Accounting Standards Update (“ASU”) 2017-09, Compensation - Stock Compensation: Scope of Modification Accounting, which provides guidance concerning which changes to the terms or conditions of842 had a share-based payment award require an entity to apply modification accounting in ASC 718.  This guidance is effective for annual and interim periods beginning after December 15, 2017. Amendments in this ASU are applied prospectively to any award modified on or after the adoption date. The Company adopted this guidance on January 1, 2018. Thematerial impact on the Company’s consolidated statement of financial position and results of operations was not material.
In March 2017, the FASB issued ASU 2017-07, Compensation - Retirement Benefits, which requires the presentation of the service cost component of the net periodic pension and postretirement benefits costsUnaudited Condensed Consolidated Balance Sheets, resulting in the same line item in the statement of operations as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of the net periodic pension and postretirement benefits costs are required to be presented as non-operating expenses in the statement of operations. This guidance is effective for annual periods beginning after December 15, 2017. The Company adopted this guidancerecognition, on January 1, 2018.2019, of a lease liability of $299,243 which represents the present value of the remaining lease payments, and a right-of-use asset of $254,245 which represents the lease liability, offset by adjustments as appropriate under ASC 842. The adoption of ASC 842 did not have a material impact on the Company’s consolidated statement of financial position and results of operations was not material.
In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows. This new guidance is intended to reduce diversity in practice regarding the classification of certain transactions in the statement of cash flows. This guidance is effective January 1, 2018 and requires a retrospective transition method. Prior to the Company’s adoption on January 1, 2018, all cash outflows for contingent consideration were classified as a financing activity. Effective January 1, 2018, the Company is now required to classify any cash payments made soon after the acquisition date of a business to settle a contingent consideration liability as cash outflows for investing activities. Cash payments which are not made soon after the acquisition date of a business to settle a contingent consideration liability are separated and classified as cash outflows for financing activities up to the amount of the contingent consideration liability recognized at the acquisition date and as cash outflows from operating activities for any excess. As a result, $36,570 of an acquisition-related contingent consideration payment of $89,126, which was in excess of the liability initially recognized at the acquisition date, has been classified as a cash outflow within net cash provided by operating activities in the accompanying consolidated statement of cash flows for the nine months ended September 30, 2017. There was no impact on the Company’s consolidated statement of financial position and results of operations.
In January 2016, the FASB issued ASU 2016-01,other Unaudited Condensed Consolidated Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Liabilitieswhich will require equity investments, except equity method investments, to be measured at fair value and any changes in fair value will be recognized in results of operations. This guidance is effective for annual and interim periods beginning after December 15, 2017. Additionally, this guidance provides for the recognition of the cumulative effect of retrospective application of the new standard in the period of initial application. The Company adopted this guidance on January 1, 2018. The impact on the Company’s consolidated statement of financial position and results of operations was not material.

In January 2018, the FASB released guidance on the accounting for tax on the global intangible low-taxed income (“GILTI”) provisions of the Tax Cuts and Jobs Act (the “Act”). The GILTI provisions impose a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. The guidance indicates that either accounting for deferred taxes related to GILTI inclusions or treating any taxes on GILTI inclusions as period cost are both acceptable methods subject to an accounting policy election. During the quarter ended September 30, 2018 the Company has made a policy election to record tax effects of GILTI as an expense in the period incurred.
Standard to be Adopted in Future Reporting Periods
In February 2016, the FASB issued ASU 2016-02, Leases. The new guidance will require lessees to recognize a right-to-use asset and lease liability for most of its leases with a term of more than twelve months, including those classified as operating leases. The new guidance also requires additional quantitative and qualitative disclosures. This guidance will be effective for annual periods beginning after December 15, 2018, with early adoption permitted. In July 2018, the FASB issued ASU 2018-11 to provide an optional transition method allowing entities to apply the new lease standard at the adoption date with a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption (modified retrospective approach) as opposed to restating prior period financial statements. The Company plans to adopt the standard on its effective date of January 1, 2019 using the modified adoption method. The Company is in the process of reviewing its lease contracts, updating its accounting policies, and implementing a new system as well as processes and internal controls to support the Company’s financial reporting and disclosure under the new standard. The Company is not yet able to assess the full impact of the application of the new guidance; however, it expects that the recognition of a right-to-use asset and lease liability for operating leases will have a significant impact on its balance sheet.Statements.

Item 2.    Management’s Discussion and Analysis of Financial Condition and Results of Operations
Unless otherwise indicated, references to the “Company” or “MDC” mean MDC Partners Inc. and its subsidiaries, and references to a “fiscal year” means the Company’s year commencing on January 1 of that year and ending December 31 of that year (e.g., fiscal 20182019 means the period beginning January 1, 2018,2019, and ending December 31, 2018)2019).
The Company reports its financial results in accordance with generally accepted accounting principles (“GAAP”) of the United States of America (“U.S. GAAP”). In addition, the Company has included certain non-U.S. GAAP financial measures and ratios, which it believes provide useful supplemental information to both management and readers of this report in measuring the financial performance and financial condition of the Company. These measures do not have a standardized meaning prescribed by U.S. GAAP and should not be construed as an alternative to other titled measures determined in accordance with U.S. GAAP.
Two such non-U.S. GAAP measures are “organic revenue growth” or “organic revenue decline” that refer to the positive or negative results, respectively, of subtracting both the foreign exchange and acquisition (disposition) components from total revenue growth, excluding the impact of adoption of Financial Accounting Standards Board (the “FASB”) Accounting Standards Codification Topic 606 (“ASC 606”).growth. The acquisition (disposition) component is calculated by aggregating the prior period revenue for any acquired businesses, less the prior period revenue of any businesses that were disposed of in the current period. The organic revenue growth (decline) component reflects the constant currency impact (a) of the change in revenue of the Partner Firms which the Company has held throughout each of the comparable periods presented and (b) “non-GAAP acquisitions (dispositions), net.” Non-GAAP acquisitions (dispositions), net consists of (i) for acquisitions during the current year, the revenue effect from such acquisition as if the acquisition had been owned during the equivalent period in the prior year and (ii) for acquisitions during the previous year, the revenue effect from such acquisitions as if they had been owned during that entire year or same period as the current reportable period, taking into account their respective pre-acquisition revenues for the applicable periods and (iii) for dispositions, the revenue effect from such disposition as if they had been disposed of during the equivalent period in the prior year. The Company believes that isolating the impact of acquisition activity and foreign currency impacts and changes in accounting standards is an important and informative component to understand the overall change in the Company’s consolidated revenue. The change in the consolidated revenue that remains after these adjustments illustrates the underlying financial performance of the Company’s businesses. Specifically, it represents the impact of the Company’s management oversight, investments and resources dedicated to supporting the businesses’ growth strategy and operations. In addition, it reflects the network benefit of inclusion in the broader portfolio of firms that includes, but is not limited to, cross-selling and sharing of best practices. This approach isolates changes in performance of the business that take place under the Company’s stewardship, whether favorable or unfavorable, and thereby reflects the potential benefits and risks associated with owning and managing a talent-driven services business.
Accordingly, during the first twelve months of ownership by the Company, the organic growth measure may credit the Company with growth from an acquired business that is dependent on work performed prior to the acquisition date, and may include the impact of prior work in progress, existing contracts and backlog of the acquired businesses. It is the presumption of the Company that positive developments that may have taken place at an acquired business during the period preceding the acquisition will continue to result in value creation in the post-acquisition period.

While the Company believes that the methodology used in the calculation of organic revenue change is entirely consistent with our closest U.S. competitors, the calculations may not be comparable to similarly titled measures presented by other publicly traded companies in other industries. Additional information regarding the Company’s acquisition activity as it relates to potential revenue growth is provided in this Item 2 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” under “Certain Factors Affecting our Business.”
The following discussion focuses on the operating performance of the Company for the three and ninesix months ended SeptemberJune 30, 20182019 and 20172018 and the financial condition of the Company as of SeptemberJune 30, 2018.2019. This analysis should be read in conjunction with the interim condensed consolidated financial statementsUnaudited Condensed Consolidated Financial Statements presented in this interim report and the annual audited consolidated financial statements and Management’s Discussion and Analysis presented in the Annual Report for the year ended December 31, 20172018 as reported on the Form 10-K (the “Annual Report on Form 10-K”). All amounts are in dollars unless otherwise stated. Amounts reported in millions herein are computed based on the amounts in thousands. As a result, the sum of the components, and related calculations, reported in millions may not equal the total amounts due to rounding.
Recent Developments
On September 12, 2018 the Company announced that Scott Kauffman will step down as the Company’s Chairman and Chief Executive Officer. He will remain in his role as Chairman and CEO until a successor is named. Mr. Kauffman is also expected to continue as a member of the MDC Board of Directors for the remainder of his current term.

On September 20, 2018, the Company announced its intention to explore and evaluate potential strategic alternatives, which may result in, among other things, the possible sale of the Company. The Company has not made a decision to pursue any specific strategic alternative, and there is no timetable for completing the strategic review process. This review process is proceeding in parallel with the Company’s search to identify a successor CEO. There can be no assurance that the Company will complete any specific action or transaction.
Executive Summary
MDC conducts its business through its network of Partner Firms, the “Advertising and Communications Group,” who provide a comprehensive array of marketing and communications services for clients both domestically and globally. The Company’s objective is to create shareholder value by building, growing and acquiring market-leading Partner Firms that deliver innovative, value-added marketing, activation, communications and strategic consulting to their clients. Management believes that shareholder value is maximized with an operating philosophy of “Perpetual Partnership” with proven committed industry leaders in marketing communications.
MDC manages its business by monitoring several financial and non-financial performance indicators. The key indicators that we focus on are revenues, operating expenses and capital expenditures. Revenue growth is analyzed by reviewing a mix of measurements, including (i) growth by major geographic location, (ii) growth by client industry vertical, (iii) growth from existing clients and the addition of new clients, (iv) growth by primary discipline (v) growth from currency changes, and (vi) growth from acquisitions. In addition to monitoring the foregoing financial indicators, the Company assesses and monitors several non-financial performance indicators relating to the business performance of our Partner Firms. These indicators may include a Partner Firm’s recent new client win/loss record; the depth and scope of a pipeline of potential new client account activity; the overall quality of the services provided to clients; and the relative strength of the Partner Firm’s next generation team that is in place as part of a potential succession plan to succeed the current senior executive team.
As discussed in Note 12 of the Notes to the Unaudited Condensed Consolidated Financial Statements included herein for the Company aggregates operating segments that meet the aggregation criteria detailed in ASC 280 into one of the four reportable segments and combines and discloses those operating segments that do not meet the aggregation criteria in the All Other category. Due to changes in the composition of certain business and the Company’s internal management and reporting structure during 2018,2019, reportable segment results for the 20172018 periods presented have been recast to reflect the reclassification of certain businesses between segments. Prior period segment information included herein has been adjusted to reflect this change. See Note 12 of the Notes to the Unaudited Condensed Consolidated Financial Statements included herein for a description of each of our reportable segments and All Other category and further information regarding the reclassification of certain businesses between segments.
The Company recognized an impairment of goodwill and other assets of $21.0 million in the three months ended and $23.3 million for the nine months ended September 30, 2018. The impairment primarily consists of the write-down of goodwill equal to the excess carrying value above the fair value of a reporting unit within the Global Integrated Agencies reportable segment and the full write-down of a trademark for a reporting unit also within the Global Integrated Agencies reportable segment. The trademark is no longer in active use given its merger with another reporting unit in the third quarter of 2018. See Note 12 of the Notes to the Unaudited Condensed Consolidated Financial Statements for information related to the merger.

During the third quarter of 2018, the Company performed an interim goodwill impairment test resulting in, along with the impairment mentioned above, the fair value of a reporting unit, with goodwill of approximately $130.0 million, exceeding its

carrying value by a minimal percentage. A reduction in the projected long-term operating performance of this reporting unit, market declines, changes in discount rates or other conditions could result in an impairment in the future. In connection with the interim impairment test, the Company used a combination of the income approach, which incorporates the use of a discounted cash flow method, and the market approach, which incorporates the use of earnings and revenue multiples based on market data. The Company applied an equal weighting to the income and market approaches for the impairment test. The income approach and the market approach both require the exercise of significant judgment, including judgment about the amount and timing of expected future cash flows, assumed terminal value and appropriate discount rates.

In addition, MDC reports its corporate office expenses incurred in connection with the strategic resources provided to the Partner Firms, as well as certain other centrally managed expenses that are not fully allocated to the operating segments as Corporate. Corporate provides client and business development support to the Partner Firms as well as certain strategic resources, including accounting, administrative, financial, real estate, human resource and legal functions. Additional expenses managed by the corporate office that are directly related to the Partner Firms are allocated to the appropriate reportable segment and the All Other category.

Revenue was $362.1 million for the three months ended June 30, 2019 compared to revenue of $379.7 million for the three months ended June 30, 2018, representing a decline of $17.6 million.

The impact of the adoption of ASC 606 reduced revenue by $8.2 million, or 2.2%, primarily due to the shift in treatment of third party costs from principal to agent for various client arrangements of certain Partner Firms and timing of revenue recognition. The other components of the change in revenue included a negative foreign exchange impact of $4.2 million, or 1.1%, and an adverse impact from dispositions of $3.8 million, or 1.0%, offset by revenue from an acquired Partner Firm of $12.7 million, or 3.4%, and an increase in revenue from existing Partner Firms of $4.6 million, or 1.2%. Excluding the impact of the adoption of ASC 606, the growth in revenue was attributable to contribution from new client wins that was partially offset by client losses and reduction in spending by some clients. Additionally, the change in revenue was driven by growth in categories including communications, transportation and lodging, and financials, offset by declines in automotive, and retail.

NINE MONTHS ENDED SEPTEMBER 30, 2018 COMPARED TO NINE MONTHS ENDED SEPTEMBER 30, 2017

Consolidated Results of Operations

Revenues
Revenue was $1.08 billion for the nine months ended September 30, 2018 compared to revenue of $1.11 billion for the nine months ended September 30, 2017, representing a decrease of $28.5 million, or 2.6%. See the Advertising and Communications Group section below for a discussion regarding consolidated revenues for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017.
Operating Profit
Operating profit for the nine months ended September 30, 2018 was $18.8 million compared to $72.0 million for the nine months ended September 30, 2017, representing a decrease of $53.2 million. The change was primarily driven by a decline in operating profit in the Advertising and Communications Group of $37.0 million, inclusive of a $21.0 million impairment pertaining to goodwill and a trademark within the Global Integrated Agencies reportable segment. Additionally, Corporate operating expenses increased by $16.3 million, primarily related to severance expense and other restructuring costs of $7.3 million, consulting fees of $2.3 million, and an impairment of a long-lived asset of $2.3 million. The impact of the adoption of ASC 606 increased operating profit by $8.9 million. Excluding the impact of the adoption of ASC 606, operating profit would have been $9.9 million, representing a decrease of $62.1 million compared to 2017.
Other, Net
Other, net, for the nine months ended September 30, 2018 was an income of $1.2 million compared to expense of $1.0 million for the nine months ended September 30, 2017, representing a change of $2.2 million.
Foreign Exchange Transaction Gain (Loss)
Foreign exchange loss of $9.9 million in the nine months ended September 30, 2018 compared to a foreign exchange gain of $18.8 million in the nine months ended September 30, 2017 is attributed to strengthening of the Canadian dollar against the U.S. dollar. The change primarily related to U.S. dollar denominated indebtedness that is an obligation of our Canadian parent company.
Interest Expense and Finance Charges, Net
Interest expense and finance charges, net, for the nine months ended September 30, 2018 was $50.0 million compared to $48.3 million for the nine months ended September 30, 2017, representing an increase of $1.7 million.
Income Tax Expense (Benefit)
The Company’s effective tax rate for the nine months ended September 30, 2018 was 8.4% compared to 42.5% for the nine months ended September 30, 2017. Income tax benefit for the nine months ended September 30, 2018 was $3.4 million compared to an expense of $17.7 million for the nine months ended September 30, 2017, representing a decrease of $21.1 million. The variance in the tax expense year over year was primarily driven by jurisdictional mix of earnings, impairments and non-deductible stock compensation in the current period for which tax benefit was not recognized as well as the impact of a valuation allowance in the U.S. in the prior period.
Equity in Earnings (Losses) of Non-Consolidated Affiliates
Equity in earnings (losses) of non-consolidated affiliates represents the income or losses attributable to equity-accounted affiliate operations. The Company recorded $0.4 million of income for the nine months ended September 30, 2018 compared to income of $1.9 million for the nine months ended September 30, 2017.

As a result of the foregoing, net loss attributable to MDC Partners Inc. common shareholders for the nine months ended September 30, 2018 was $48.3 million, or $0.85 diluted loss per share, compared to net income attributable to MDC Partners Inc. common shareholders of $13.0 million, or $0.24 diluted income per share, for the nine months ended September 30, 2017.

Advertising and Communications Group
The following discussion provides additional detailed disclosure for each of the Company’s four (4) reportable segments, plus the “All Other” category, within the Advertising and Communications Group.
Revenue for the Advertising and Communications Group was $1.08 billion for the nine months ended September 30, 2018 compared to revenue of $1.11 billion for the nine months ended September 30, 2017, representing a decrease of $28.5 million, or 2.6%. The impact of the adoption of ASC 606 reduced revenue by $39.2 million, or 3.5%, primarily due to the shift in treatment of third party costs from principal to agent for various client arrangements of certain Partner Firms and timing of revenue recognition. The other components of the change in revenue included a negative impact from dispositions of $14.7 million, or 1.3%, and a decline in revenue from existing Partner Firms of $2.2 million, or 0.2%, partially offset by revenue contributions from an acquired Partner Firm of $23.8 million and a positive foreign exchange impact of $4.5 million, or 0.4%. Excluding the impact of the adoption of ASC 606, revenue growth was attributable to new client wins, partially offset by cutbacks and delays from several existing clients. Additionally, the change in revenue was driven by decline in categories including automotive and retail, partially offset by growth in transportation and lodging, financials, and healthcare.
Revenue change was mixed through the geographic regions with declines of 2.4% and 7.2% in the United States and other regions outside of North America, respectively, partially offset by growth in Canada of 3.5%. The adoption of ASC 606 had a mixed impact on all geographic regions. The impact increased revenue in Canada by 2.7%, and decreased revenue in the United States and outside of North America by 1.9% and 16%, respectively.
The Company also utilizes non-GAAP metrics called organic revenue growth (decline) and non-GAAP acquisitions (dispositions), net, as defined above. For the nine months ended September 30, 2018, organic revenue increased $2.2 million, or 0.2%, of which $2.2 million, or 0.2% of decline pertained to Partner Firms which the Company has owned throughout each of the comparable periods presented. The remaining organic revenue growth of $4.4 million, or 0.4% was generated from an acquired Partner Firm. The other components of non-GAAP activity included a negative non-GAAP acquisition (disposition), net adjustment of $4.1 million, or 0.4%, and a positive foreign exchange impact of $4.5 million, or 0.4%.
The components of the fluctuations in revenues for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017 are as follows:

The decrease in direct costs was primarily attributed to the adoption of ASC 606 in which various client arrangements of certain Partner Firms previously accounted for as principal are accounted for as agent under ASC 606. The change resulted in a decrease in third party costs included in revenue of $48.1 million.
The increase in staff costs was primarily attributed to contributions from an acquired Partner Firm, higher costs to support the growth of certain Partner Firms, partially offset by staffing reductions at other Partner Firms. As a percentage of revenue, the increase in staff costs was primarily due to the impact of the adoption of ASC 606 on revenue.
Deferred acquisition consideration change was primarily attributable to an increase in the acquisition consideration liability pertaining to amendments to purchase agreements of previously acquired incremental ownership interest entered into during 2017.

The decrease in direct costs was primarily due to the adoption of ASC 606 in which various client arrangements of certain Partner Firms previously accounted for as principal are accounted for as agent under ASC 606. The change resulted in a decrease in third party costs included in revenue of $48.1 million.
The increase in staff costs was attributed to higher costs to support the growth of certain Partner Firms, partially offset by staffing reductions at other firms. As a percentage of revenue, staff costs increased due to a decline in revenue from the adoption of ASC 606.
Deferred acquisition consideration change was primarily attributable to an increase in the acquisition consideration liability pertaining to amendments to purchase agreements of previously acquired incremental ownership interest entered into during 2017.

The decline in revenue from existing Partner Firms was attributable to client losses and a reduction in spending by certain clients, partially offset by new client wins. Additionally, the change in revenue was driven by a decline in categories including health care, food and beverage and automotive, partially offset by growth in transportation and technology.

The Company intends to maintain sufficient cash and/or available borrowings to fund operations for the next twelve months. The Company has historically been able to maintain and expand its business using cash generated from operating activities, funds available under its Credit Agreement, and other initiatives, such as obtaining additional debt and equity financing. At SeptemberJune 30, 2018,2019, the Company had $103.0$27.5 million of borrowings outstanding and $127.5$202.7 million available under the Credit Agreement.
The Company’s obligations extending beyond twelve months primarily consist of deferred acquisition payments, capital expenditures, scheduled lease obligation payments, and interest payments on borrowings under the Company’s 6.50% Senior Notes due 2024. Based on the current outlook, the Company believes future cash flows from operations, together with the Company’s existing cash balance and availability of funds under the Company’s Credit Agreement, will be sufficient to meet the Company’s anticipated cash needs for the foreseeable future. The Company’s ability to make scheduled deferred acquisition payments, principal and interest payments, to refinance indebtedness or to fund planned capital expenditures will depend on future performance, which is subject to general economic conditions, the competitive environment and other factors, including those described in the Company’s 20172018 Annual Report on Form 10-K and in the Company’s other SEC filings.
As market conditions warrant, the Company may from time to time seek to purchase its notes, in privately negotiated or open market transactions, by tender offer or otherwise. Subject to any applicable limitations contained in the agreements governing its indebtedness, any purchase made by the Company may be funded by the net proceeds from any asset dispositions or the use of cash on its balance sheet. The amounts involved in any such purchase transactions, individually or in the aggregate, may be material.
Working Capital
At SeptemberJune 30, 2018,2019, the Company had a working capital deficit of $181.7$184.6 million compared to a deficit of $232.9$152.7 million at December 31, 2017. Working capital deficit decreased by $51.1 millionprimarily due to timing of media payments, partially offset by net borrowings on the Company’s credit agreement.2018. The Company’s working capital is impacted by seasonality in media buying, amounts spent by clients, and timing of amounts received from clients and subsequently paid to suppliers. Media buying is impacted by the timing of certain events, such as major sporting competitions and national holidays, and there can be a quarter to quarter lag between the time amounts received from clients for the media buying are subsequently paid to suppliers.
The Company intends to maintain sufficient cash or availability of funds under the Credit Agreement at any particular time to adequately fund working capital should there be a need to do so from time to time.
Cash Flows

Cash flows used in operating activities for the ninesix months ended SeptemberJune 30, 2019 was $40.2 million, primarily reflecting unfavorable working capital requirements, driven by media and other supplier payments.
Cash flows used in operating activities for the six months ended June 30, 2018 was 31.7$61.7 million, primarily reflecting unfavorable working capital requirements, driven by media and other supplier payments, deferred acquisition consideration payments as well as acquisition related contingent consideration payments, partially offset by net income (loss) adjusted to reconcile to net cash used in operating activities.
Cash flows used in operating activities for the nine months ended September 30, 2017 was $14.5 million, primarily reflecting unfavorable working capital requirements, driven by timing of accounts receivable, as well as acquisition related contingent consideration payments, partially offset by net income (loss) adjusted to reconcile to net cash used in operating activities.

During the six months ended June 30, 2018, cash flows used in investing activities was $48.4$36.1 million, which primarily consisting of cash paid of $34.3$27.3 million for acquisitions (see Note 4the acquisition of the Notes to the Unaudited Condensed Consolidated Financial Statements for additional information)Instrument and capital expenditures related primarily to computer equipment, furniture and fixtures, and leasehold improvements of $15.2 million, of which $7.9 million was incurred by the Global Integrated Agencies segment.
During the nine months ended September 30, 2017, cash flows used in investing activities was $19.5 million, primarily consisting of capital expenditures related primarily to computer equipment, furniture and fixtures, and leasehold improvements of $28.3 million, of which $17.6 million was incurred by the Global Integrated Agencies segment. These outflows were partially offset by net proceeds from sale of three subsidiaries of $11.1$9.7 million.
Financing Activities
During the ninesix months ended SeptemberJune 30, 2019, cash flows provided by financing activities was $25.7 million, primarily driven by $98.6 million in proceeds, net of fees from the issuance of common and preferred shares, partially offset by $40.6 million in net repayments under the Credit Agreement, and $24.2 million in deferred acquisition consideration payments
During the six months ended June 30, 2018, cash flows provided by financing activities was $59.1$76.3 million, primarily driven by $103.0$115.2 million in net borrowings under the Credit Agreement partially offset by $32.2 million of acquisition related payments and distributions to noncontrolling partners of $10.4 million.
During the nine months ended September 30, 2017, cash flows provided by financing activities was $24.9 million, primarily driven by $95.0 million in proceeds from the issuance of convertible preference shares, partially offset by $5.8 million in net repayments under the Credit Agreement and $52.6$29.2 million of acquisition related payments.
Total Debt
Debt, net of debt issuance costs, as of SeptemberJune 30, 20182019 was $988.2$914.1 million an increase of $105.1 million,as compared with $883.1to $954.1 million outstanding at December 31, 2017.  This increase2018. The decrease of $40 million in debt was primarily a result of the Company’s net borrowingsrepayments on the Credit Agreement. See Note 67 of the Notes to the Unaudited Condensed Consolidated Financial Statements for information regarding the Company’s $900 million aggregate principal amount of its senior unsecured notes due 2024 and $325$250 million senior secured revolving credit agreement due May 3, 2021 (the “Credit Agreement”).
The Company is currently in compliance with all of the terms and conditions of the Credit Agreement, and management believes, based on its current financial projections, that the Company will be in compliance with its covenants over the next twelve months.
If the Company loses all or a substantial portion of its lines of credit under the Credit Agreement, or if the Company uses the maximum available amount under the Credit Agreement, it will be required to seek other sources of liquidity. If the Company were unable to find these sources of liquidity, for example through an equity offering or access to the capital markets, the Company’s ability to fund its working capital needs and any contingent obligations with respect to acquisitions and redeemable noncontrolling interests would be adversely affected.
Pursuant to the Credit Agreement, the Company must comply with certain financial covenants including, among other things, covenants for (i) senior leverage ratio, (ii) total leverage ratio, (iii) fixed charges ratio, and (iv) minimum earnings before interest, taxes and depreciation and amortization, in each case as such term is specifically defined in the Credit Agreement. For the period ended SeptemberJune 30, 2018,2019, the Company’s calculation of each of these covenants, and the specific requirements under the Credit Agreement, respectively, were calculated based on the trailing twelve months as follows:

These ratios and measures are not based on generally accepted accounting principles and are not presented as alternative measures of operating performance or liquidity. Some of these ratios and measures include, among other things, pro forma adjustments for acquisitions, one-time charges, and other items, as defined in the Credit Agreement. They are presented here to

demonstrate compliance with the covenants in the Credit Agreement, as non-compliance with such covenants could have a material adverse effect on the Company.

Commitments, Contingencies, and Guarantees
The Company’s agencies enter into contractual commitments with media providers and agreements with production companies on behalf of our clients at levels that exceed the revenue from services. Some of our agencies purchase media for clients and act as an agent for a disclosed principal. These commitments are included in accounts payable when the media services are delivered by the media providers. MDC takes precautions against default on payment for these services and has historically had a very low incidence of default. MDC is still exposed to the risk of significant uncollectible receivables from our clients. The risk of a material loss could significantly increase in periods of severe economic downturn.
Deferred acquisition consideration on the balance sheet consists of deferred obligations related to contingent and fixed purchase price payments, and to a lesser extent, contingent and fixed retention payments tied to continued employment of specific personnel. See Note 5 of the Notes to the Unaudited Condensed Consolidated Financial Statements for additional information regarding contingent deferred acquisition consideration.
The following table presents the changes in the deferred acquisition consideration by segment for the ninesix months ended SeptemberJune 30, 2018:2019:

(1)Additions are the initial estimated deferred acquisition payments of new acquisitions and step-up transactions completed within that fiscal period.
(2)Redemption value adjustments are fair value changes from the Company’s initial estimates of deferred acquisition payments including the accretion of present value and stock-based compensation charges relating to acquisition payments that are tied to continued employment.
Deferred acquisition consideration excludes future payments with an estimated fair value of $22.6$8.6 million that are contingent upon employment terms as well as financial performance and will be expensed as stock-based compensation over the required retention period. Of this amount, the Company estimates $0.1$0.2 million will be paid in the current year $15.4and $8.4 million will be paid in one to three years and $7.1 million will be paid in three to five years.
When acquiring less than 100% ownership of an entity, the Company may enter into agreements that give the Company an option to purchase, or require the Company to purchase, the incremental ownership interests under certain circumstances. Where the incremental purchase may be required of the Company, the amounts are recorded as redeemable noncontrolling interests in mezzanine equity. See Note 89 of the Notes to the Unaudited Condensed Consolidated Financial Statements for additional information regarding redeemable noncontrolling interest.
The Company intends to finance the cash portion of these contingent payment obligations using available cash from operations, borrowings under the Credit Agreement (and refinancings thereof), and, if necessary, through the incurrence of additional debt and/or issuance of additional equity. The ultimate amount payable and the incremental operating income in the future relating to these transactions will vary because it is dependent on the future results of operations of the subject businesses and the timing of when these rights are exercised.

The following table summarizes the potential timing of the consideration and incremental operating income before depreciation and amortization based on assumptions as described above:

Item 3.    Quantitative and Qualitative Disclosures About Market Risk
The Company is exposed to market risk related to interest rates, foreign currencies and impairment risk.
Debt Instruments:  At SeptemberJune 30, 2018,2019, the Company’s debt obligations consisted of amounts outstanding under its Credit Agreement and the Senior Notes. The Senior Notes bear a fixed 6.50% interest rate. The Credit Agreement bears interest at variable rates based upon the Eurodollar rate, U.S. bank prime rate and U.S. base rate, at the Company’s option. The Company’s ability to obtain the required bank syndication commitments depends in part on conditions in the bank market at the time of syndication. Given that there were $103.0$27.5 million borrowings under the Credit Agreement, as of SeptemberJune 30, 2018,2019, a 1.0% increase or decrease in the weighted average interest rate, which was 4.06%5.01% at SeptemberJune 30, 2018,2019, would have an interest impact of approximately $1.0$0.3 million.
Foreign Exchange:  While the Company primarily conducts business in markets that use the U.S. dollar, the Canadian dollar, the European Euro and the British Pound, its non-U.S. operations transact business in numerous different currencies. The Company’s results of operations are subject to risk from the translation to the U.S. dollar of the revenue and expenses of its non-U.S. operations. The effects of currency exchange rate fluctuations on the translation of the Company’s results of operations are discussed in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and in Note 2 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2017.2018. For the most part, revenues and expenses incurred related to the non-U.S. operations are denominated in their functional currency. This minimizes the impact that fluctuations in exchange rates will have on profit margins. Translation of intercompany debt, which is not intended to be repaid, is included in cumulative translation adjustments. Translation of current intercompany balances are included in net earnings. The Company generally does not enter into foreign currency forward exchange contracts or other derivative financial instruments to hedge the effects of adverse fluctuations in foreign currency exchange rates.
The Company is exposed to foreign currency fluctuations relating to its intercompany balances between the U.S. and Canada. For every one cent change in the foreign exchange rate between the U.S. and Canada, the impact to the Company’s financial statements would be approximately $3.2$1.0 million.
Impairment Risk: At June 30, 2019, the Company had goodwill of $743.6 million and other intangible assets of $60.8 million. The Company has recognized an impairment ofreviews goodwill and other intangible assets with indefinite lives not subject to amortization for impairment annually as of $23.3 millionOctober 1st of each year or more frequently if indicators of potential impairment exist. See the Critical Accounting Policies and Estimates section in the Company’s 2018 Form 10-K for the nine months ended September 30, 2018. Theinformation related to impairment primarily consists of the write-down of goodwill equal to the excess carrying value above fair value of a reporting unit within the Global Integrated Agencies reportable segmenttesting and the full write-downrisk of a trademark for a reporting unit also within the Global Integrated Agencies reportable segment. See Note 11 of the Notes to the Unaudited Condensed Consolidated Financial Statements for further information.potential impairment charges in future periods.

Item 4.    Controls and Procedures
Evaluation of Disclosure Controls and Procedures
We maintain disclosure controls and procedures designed to ensure that information required to be included in our SEC reports is recorded, processed, summarized and reported within the applicable time periods specified by the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer (“CEO”),

who is our principal executive officer, and Chief Financial Officer (“CFO”), who is our principal financial officer, as appropriate, to allow timely decisions regarding required disclosures. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can provide only reasonable assurance of achieving their control objectives. However, our disclosure controls and procedures are designed to provide reasonable assurances of achieving our control objectives.
We conducted an evaluation, under the supervision and with the participation of our management, including our CEO, CFO and management Disclosure Committee, of the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report pursuant to Rule 13a-15(e) and 15(d)-15(e) of the Exchange Act. Based on that evaluation, our CEO and CFO concluded that, as of SeptemberJune 30, 2018,2019, our disclosure controls and procedures are effective to ensure that decisions can be made timely with respect to required disclosures, as well as ensuring that the recording, processing, summarization and reporting of information required to be included in our Quarterly Report on Form 10-Q for the quarter ended SeptemberJune 30, 20182019 is appropriate.

PART II. OTHER INFORMATION
 
Item 1.    Legal Proceedings
The Company’s operating entities are involved in legal proceedings of various types. While any litigation contains an element of uncertainty, the Company has no reason to believe that the outcome of such proceedings or claims will have a material adverse effect on its financial condition or results of operations.
Dismissal of Class Action Litigation in Canada
On August 7, 2015, Roberto Paniccia issued a Statement of Claim in the Ontario Superior Court of Justice in the City of Brantford, Ontario seeking to certify a class action suit naming the following as defendants: MDC, former CEO Miles S. Nadal, former CAO Michael C. Sabatino, CFO David Doft and BDO U.S.A. LLP.  The Plaintiff alleged violations of section 138.1 of the Ontario Securities Act (and equivalent legislation in other Canadian provinces and territories) as well as common law misrepresentation based on allegedly materially false and misleading statements in the Company’s public statements, as well as omitting to disclose material facts with respect to the SEC investigation.  On June 4, 2018, the Court dismissed (with costs) the putative class members’ motion for leave to proceed with the Plaintiff’s claims for misrepresentations of material facts pursuant to the Ontario Securities Act. Following the Court’s decision, on June 18, 2018, the Plaintiff, MDC and each of the other defendants consented to the dismissal of the action with prejudice (and without costs). In July 2018, the Court entered a final order approving the dismissal of this claim.
Antitrust Subpoena
In 2016, one of the Company’s subsidiary agencies received a subpoena from the U.S. Department of Justice Antitrust Division (the “DOJ”) concerning the DOJ’s ongoing investigation of production bidding practices in the advertising industry. The Company and its subsidiary are fully cooperating with this confidential investigation. Specifically, the Company and its subsidiary are providing information and engaging in discussions with the DOJ, including preliminary discussions regarding the feasibility of a potential settlement with the DOJ. However, there can be no assurance as to the timing of any settlement or that a settlement will be reached on any particular terms or at all. Moreover, the DOJ may determine to expand the scope of its investigation or initiate a proceeding to bring charges against our subsidiary or one or more members of the subsidiary agency’s former management. The DOJ may also seek to impose monetary sanctions.
Item 1A.    Risk Factors
Except for the following new risk factor, thereThere are no material changes in the risk factors set forth in Part I, Item 1A of the Company’s Annual Report on Form 10-K for the year ended December 31, 2017.
While we are exploring and evaluating strategic alternatives, we may not be successful in identifying or completing any strategic alternative and any such strategic alternative may not yield additional value for shareholders.
On September 20, 2018, we announced that we had commenced a review of strategic alternatives which could result in, among other things, the possible sale of the Company.  Our exploration of strategic alternatives may not result in the identification or consummation of any transaction.  In addition, we may incur substantial expenses associated with identifying and evaluating potential strategic alternatives.  The process of exploring strategic alternatives may be time consuming and disruptive to our business operations, and if we are unable to effectively manage the process, our business, financial condition and results of operations could be adversely affected.  Any potential transaction and the related valuation would be dependent upon a number of factors that may be beyond our control, including, among other factors, market conditions, industry trends, the interest of third parties in our business and the availability of financing to potential buyers on reasonable terms.
