Revenue from Contract with Customer [Abstract]

Revenue from Contract with Customer [Text Block]

Contract assets are primarily comprised of contract incentives that are generally satisfied annually under the terms of our contracts and are transferred to accounts receivable when the right to payment becomes unconditional. Contract liabilities relate to advance consideration received from customers under the terms of our contracts primarily related to reimbursements of third-party expenses, whether we act as principal or agent, and to a lesser extent, periodic retainer fees, both of which are generally recognized shortly after billing.

The majority of our contracts are for periods of one year or less with the exception of our data management contracts. For those contracts with a term of more than one year, we had approximately $780.3 of unsatisfied performance obligations as of December 31, 2022, which will be recognized as services are performed over the remaining contractual terms through 2027.
