(23)	Revenues from contracts with customers

As discussed in Note 1(w), on January 1, 2018, we adopted ASC 606 “Revenues from Contracts with Customers.” Except as described in Note 1, our revenue recognition practices for contracts with customers under ASC 606 do not differ significantly from prior practices. Under ASC 606, revenues are recognized when a good or service is transferred to a customer. A good or service is transferred when (or as) the customer obtains control of that good or service. Revenues are based on the consideration we expect to receive in connection with our promises to deliver goods and services to our customers.

The following table summarizes customer contract revenues disaggregated by reportable segment and the source of the revenue for the year ended December 31, 2018 (in millions). Other revenues included in our consolidated revenues were primarily insurance premiums earned, interest, dividend and other investment income and leasing revenues which are not within the scope of ASC 606.
