[1] Upon the adoption of Topic 606, we present customer deposits as “Contract liabilities” as they are received prior to transferring the related product or service to the customer. We recognize revenue upon satisfaction of the related contract performance obligation(s). Deposits received from GES’ events accommodation services are not classified as contract liabilities as they are deposits from hotel guests that are passed on to the hotels. Refer to Note 2 – Revenue and Related Contract Costs and Contract Liabilities for additional information.

[2] In connection with the adoption of Topic 606, we elected to more prominently present contract liabilities on the Consolidated Balance Sheets. Consequently, customer deposits of $33.4 million as of December 31, 2017, have been reclassified to “Contract liabilities” and to other certain current liabilities to conform to the current period presentation.
