[1] | North America includes revenue from the United States of $410.5 million and $476.3 million for the three months ended September 30, 2017 and 2016, respectively, and $1,317.9 million and $1,477.7 million for the nine months ended September 30, 2017 and 2016, respectively. International includes revenue from the United Kingdom of $82.2 million and $73.5 million for the three months ended September 30, 2017 and 2016, respectively, and $222.1 million and $225.9 million for the nine months ended September 30, 2017 and 2016, respectively. There were no other individual countries that represented more than 10% of consolidated total revenue for the three and nine months ended September 30, 2017 and 2016. In prior periods, revenue was attributed to individual countries based on the domicile of the legal entities within the Company's consolidated group that undertook those transactions. Beginning in the second quarter of 2017, the Company updated its attribution of revenue by country in the current period to be based on the location of the customer. Prior period revenue amounts by country have been retrospectively adjusted to reflect that change in attribution.
