The Company recorded amortization of costs to obtain contracts of $3.2 million and $2.2 million for the three months ended September 30, 2019 and 2018, respectively, and $8.7 million and $6.2 million for the nine months ended September 30, 2019 and 2018, respectively, in Sales and marketing in the consolidated statements of operations.

The majority of unbilled receivables arise from fixed price escalators included in the Company's long-term Customer Agreements.  The escalator is included in calculating the total estimated transaction value for an individual Customer Agreement.  The total estimated transaction value is then recognized evenly over the term of the Customer Agreement.  The amount of unbilled receivables increases while current period billings for an individual Customer Agreement are less than the current period revenue recognized for that Customer Agreement.  Conversely, the amount of unbilled receivables decreases when the actual current period billings become higher than the current period revenue recognized. At the end of the initial term of a Customer Agreement, the cumulative amounts recognized as revenue and billed to date are the same, therefore the unbilled receivable balance for an individual Customer Agreement will be zero.
