Interpublic Group of Companies (IPG)

Revenue Recognition

Our revenues are primarily derived from the planning and execution of advertising, marketing and communications programs in various media around the world. Our revenue is directly dependent upon the advertising, marketing and corporate communications requirements of our clients. Our revenue tends to be higher in the second half of the calendar year as a result of the holiday season and lower in the first half as a result of the post-holiday slow-down in client activity.

Most of our client contracts are individually negotiated and accordingly, the terms of client engagements and the bases on which we earn commissions and fees vary significantly. Our client contracts are complex arrangements that may include provisions for

incentive compensation and vendor rebates and credits. Our largest clients are multinational entities and, as such, we often provide services to these clients out of multiple offices and across many of our agencies. In arranging for such services, it is possible that we will enter into global, regional and local agreements. Multiple agreements of this nature are reviewed by legal counsel to determine the governing terms to be followed by the offices and agencies involved.

Revenue for our services is recognized when all of the following criteria are satisfied: (i) persuasive evidence of an arrangement exists; (ii) the price is fixed or determinable; (iii) collectibility is reasonably assured; and (iv) services have been performed. Depending on the terms of a client contract, fees for services performed can be recognized in three principal ways: proportional performance, straight-line (or monthly basis) or completed contract.

Depending on the terms of the client contract, revenue is derived from diverse arrangements involving fees for services performed, commissions, performance incentive provisions and combinations of the three. Commissions are generally earned on the date of the broadcast or publication. Contractual arrangements with clients may also include performance incentive provisions designed to link a portion of our revenue to our performance relative to both qualitative and quantitative goals. Performance incentives are recognized as revenue for quantitative targets when the target has been achieved and for qualitative targets when confirmation of the incentive is received from the client. Incremental direct costs incurred related to contracts where revenue is accounted for on a completed contract basis are generally expensed as incurred. There are certain exceptions made for significant contracts or for certain agencies where the majority of the contracts are project-based and systems are in place to properly capture appropriate direct costs.

Substantially all of our revenue is recorded as the net amount of our gross billings less pass-through expenses charged to a client. In most cases, the amount that is billed to clients significantly exceeds the amount of revenue that is earned and reflected in our financial statements, because of various pass-through expenses such as production and media costs. In compliance with Emerging Issues Task Force (“EITF”) Issue No. 99-19, Reporting Revenue Gross as a Principal versus Net as an Agent, we assess whether our agency or the third-party supplier is the primary obligor. We evaluate the terms of our client agreements as part of this assessment. In addition, we give appropriate consideration to other key indicators such as latitude in establishing price, discretion in supplier selection and credit risk to the vendor. Because we operate broadly as an advertising agency, based on our primary lines of business and given the industry practice to generally record revenue on a net versus gross basis, we believe that there must be strong evidence in place to overcome the presumption of net revenue accounting. Accordingly, we generally record revenue net of pass-through charges as we believe the key indicators of the business suggest we generally act as an agent on behalf of our clients in our primary lines of business. In those businesses (primarily sales promotion, event, sports and entertainment marketing) where the key indicators suggest we act as a principal, we record the gross amount billed to the client as revenue and the related costs incurred as office and general expenses. Revenue is reported net of taxes assessed by governmental authorities that are directly imposed on our revenue-producing transactions.

As we provide services as part of our core operations, we generally incur incidental expenses, which, in practice, are commonly referred to as “out-of-pocket” expenses. These expenses often include expenses related to airfare, mileage, hotel stays, out of town meals and telecommunication charges. In accordance with EITF Issue No. 01-14, Income Statement Characterization of Reimbursements Received for ‘Out-of-Pocket’ Expenses Incurred, we record the reimbursements received for incidental expenses as revenue with a corresponding offset to office and general expense.

We receive credits from our vendors and media outlets for transactions entered into on behalf of our clients that, based on the terms of our contracts and local law, are either remitted to our clients or retained by us. If amounts are to be passed through to clients

they are recorded as liabilities until settlement or, if retained by us, are recorded as revenue when earned. Negotiations with a client at the close of a current engagement could result in either payments to the client in excess of the contractual liability or in payments less than the contractual liability. These items, referred to as concessions, relate directly to the operations of the period and are recorded as operating expense or income. Concession income or expense may also be realized in connection with settling vendor discount or credit liabilities that were established as part of the restatement we presented in our Annual Report on Form 10-K for the year ended December 31, 2004 that we filed in September 2005 (the “2004 Restatement”). In these situations, and given the historical nature of these liabilities, we have recorded such items as other income or expense in order to prevent distortion of current operating results. We release certain of these credit liabilities when the statute of limitations has lapsed, unless the liabilities are associated with customers with whom we are in the process of settling such liabilities. These amounts are reported in other income (expense).

The determination as to whether revenue in a particular line of business should be recognized net or gross involves complex judgments.

If it were determined that we must recognize a significant portion of revenues on a gross basis rather than a net basis it would positively impact revenues, have no impact on our operating income and have an adverse impact on operating margin.

Depending on the terms of a client contract, fees for services performed can be recognized in three principal ways: proportional performance, straight-line (or monthly basis) or completed contract.

Depending on the terms of the client contract, revenue is derived from diverse arrangements involving fees for services performed, commissions, performance incentive provisions and combinations of the three. Commissions are generally earned on the date of the broadcast or publication. Contractual arrangements with clients may also include performance incentive provisions designed to link a portion of our revenue to our performance relative to both qualitative and quantitative goals. Performance incentives are recognized as revenue for quantitative targets when the target has been achieved and for qualitative targets when confirmation of the incentive is received from the client. Incremental direct costs incurred related to contracts where revenue is accounted for on a completed contract basis are generally expensed as incurred. There are certain exceptions made for significant contracts or for certain agencies where the majority of the contracts are project-based and systems are in place to properly capture appropriate direct costs.

Substantially all of our revenue is recorded as the net amount of our gross billings less pass-through expenses charged to a client. In most cases, the amount that is billed to clients significantly exceeds the amount of revenue that is earned and reflected in our financial statements, because of various pass-through expenses such as production and media costs. In compliance with Emerging Issues Task Force (“EITF”) Issue No. 99-19, Reporting Revenue Gross as a Principal versus Net as an Agent, we assess whether our agency or the third-party supplier is the primary obligor. We evaluate the terms of our client agreements as part of this assessment. In addition, we give appropriate consideration to other key indicators such as latitude in establishing price, discretion in supplier selection and credit risk to the vendor. Because we operate broadly as an advertising agency, based on our primary lines of business and given the industry practice to generally record revenue on a

net versus gross basis, we believe that there must be strong evidence in place to overcome the presumption of net revenue accounting. Accordingly, we generally record revenue net of pass-through charges as we believe the key indicators of the business suggest we generally act as an agent on behalf of our clients in our primary lines of business. In those businesses (primarily sales promotion, event, sports and entertainment marketing) where the key indicators suggest we act as a principal, we record the gross amount billed to the client as revenue and the related costs incurred as office and general expenses. Revenue is reported net of taxes assessed by governmental authorities that are directly imposed on our revenue-producing transactions.

As we provide services as part of our core operations, we generally incur incidental expenses, which, in practice, are commonly referred to as “out-of-pocket” expenses. These expenses often include expenses related to airfare, mileage, hotel stays, out of town meals and telecommunication charges. In accordance with EITF Issue No. 01-14, Income Statement Characterization of Reimbursements Received for ‘Out-of-Pocket’ Expenses Incurred, we record the reimbursements received for incidental expenses as revenue with a corresponding offset to office and general expense.

We receive credits from our vendors and media outlets for transactions entered into on behalf of our clients that, based on the terms of our contracts and local law, are either remitted to our clients or retained by us. If amounts are to be passed through to clients they are recorded as liabilities until settlement or, if retained by us, are recorded as revenue when earned. Negotiations with a client at the close of a current engagement could result in either payments to the client in excess of the contractual liability or in payments less than the contractual liability. These items, referred to as concessions, relate directly to the operations of the period and are recorded as operating expense or income. Concession income or expense may also be realized in connection with settling vendor discount or credit liabilities that were established as part of the restatement we presented in our Annual Report on Form 10-K for the year ended December 31, 2004 that we filed in September 2005 (the “2004 Restatement”). In these situations, and given the historical nature of these liabilities, we have recorded such items as other income or expense in order to prevent distortion of current operating results. We release certain of these credit liabilities when the statute of limitations has lapsed, unless the liabilities are associated with customers with whom we are in the process of settling such liabilities. These amounts are reported in other income (expense).
