## OMNICOM GROUP INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

Equity Method Investments.  Investments in companies where we exercise significant influence over the operating and financial policies of the investee and own less than 50% of the equity are accounted for using the equity method. Our proportionate share of the net income or loss of equity method investments is included in results of operations and any dividends received reduce the carrying value of the investment. The excess of the cost of our investment over our proportionate share of the fair value of the net assets of the investee at the acquisition date is recognized as goodwill and included in the carrying amount of the investment. Goodwill in the equity method investments is not amortized. Gains and losses from changes in our ownership interests are recorded in results of operations until control is achieved. In circumstances where a change in our ownership interest results in obtaining control, the existing carrying value of the investment is remeasured to the acquisition date fair value and any gain or loss is recognized in results of operations. We periodically review the carrying value of the equity method investments to determine if there has been an other-than-temporary decline in carrying value. A variety of factors are considered when determining if a decline in carrying value is other-than- temporary, including the financial condition and business prospects of the investee, as well as our investment intent. 

Marketable Equity Securities.  Marketable equity securities are measured at fair value and changes in fair value are recognized in results of operations. 

Non-Marketable Equity Securities . Non-marketable equity securities do not have a readily determinable fair value and are measured at cost, less any impairment, and are adjusted for observable changes in fair value from transactions for identical or similar securities of the same issuer. 

Goodwill and Intangible Assets.  Goodwill represents the excess of the acquisition cost over the fair value of the net assets acquired. Goodwill is not amortized but is periodically reviewed for impairment. Intangible assets comprise customer relationships, including the related customer contracts and trade names, and purchased and internally developed software and are amortized over their estimated useful lives ranging from five to twelve years. We consider a number of factors in determining the useful lives and amortization method, including the pattern in which the economic benefits are consumed, as well as trade name recognition and customer attrition. There is no estimated residual value for the intangible assets. 

We review the carrying value of goodwill for impairment annually at June 30 and whenever events or circumstances indicate the carrying value may not be recoverable. The impairment evaluation compares the fair value of each reporting unit, which we identified as our five agency networks, to its carrying value, including goodwill. If the fair value of the reporting unit is equal to or greater than its carrying value, goodwill is not impaired. Goodwill is impaired when the carrying value of the reporting unit exceeds its fair value. Goodwill is written down to its fair value through a non-cash expense recorded in results of operations in the period the impairment is identified. 

We identified our regional reporting units as components of our operating segments, which are our five agency networks. The regional reporting units and practice areas of each agency network monitor the performance and are responsible for the agencies in their region. The regional reporting units report to the segment managers and facilitate the administrative and logistical requirements of our client-centric strategy for delivering services to clients in their regions. We have concluded that, for each of our operating segments, their regional reporting units had similar economic characteristics and should be aggregated for purposes of testing goodwill for impairment at the operating segment level. Our conclusion was based on a detailed analysis of the aggregation criteria set forth in FASB ASC Topic 280, Segment Reporting , and the guidance set forth in FASB ASC Topic 350, Intangibles - Goodwill and Other . Consistent with our fundamental business strategy, the agencies within our regional reporting units serve similar clients in similar industries, and in many cases the same clients. The main economic components of each agency are employee compensation and related costs and direct service costs and occupancy and other costs, which include rent and occupancy costs, technology costs that are generally limited to personal computers, servers and off-the-shelf software and other overhead costs. Finally, the expected benefits of our acquisitions are typically shared by multiple agencies in various regions as they work together to integrate the acquired agency into our client service strategy. We use the following valuation methodologies to determine the fair value of our reporting units: (1) the income approach, which utilizes discounted expected future cash flows, (2) comparative market participant multiples of EBITDA (earnings before interest, taxes, depreciation and amortization) and (3) when available, consideration of recent and similar acquisition transactions. 

Based on the results of the annual impairment test, we concluded that at June 30, 2019 and 2018 goodwill was not impaired because either the fair value of each reporting unit was substantially in excess of its respective net book value, or for reporting units with a negative book value, fair value of assets exceeds total assets. Subsequent to the annual impairment test of goodwill at June 30, 2019, there have been no events or circumstances that triggered the need for an interim impairment test. 

Debt Issuance Costs. Debt issuance costs are capitalized and amortized in interest expense over the life of the related debt and are presented as a reduction to the carrying amount of debt. 

Temporary Equity - Redeemable Noncontrolling Interests.  Owners of noncontrolling equity interests in some of our subsidiaries have the right in certain circumstances to require us to purchase all or a portion of their equity interests at fair value as defined in the applicable agreements. The intent of the parties is to approximate fair value at the time of redemption by using a multiple of earnings that is consistent with generally accepted valuation practices used by market participants in our industry.
