With 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). We reclassified $2.5 million of GES’ events accommodation services deposits out of “Contract liabilities” to “Other current liabilities” on the December 31, 2017 Condensed Consolidated Balance Sheet as they do not represent “Contract liabilities” but rather 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.
