Non-U.S. Activities

We define our non-U.S. activities as those revenue-producing business activities that arise from clients which are generally serviced or managed outside the U.S. Due to the integrated nature of our business, precise segregation of our U.S. and non-U.S. activities is not possible. Subjective estimates, assumptions and other judgments are applied to quantify the financial results and assets related to our non-U.S. activities, including our application of funds transfer pricing, our asset-and-liability management policies and our allocation of certain indirect corporate expenses. Management periodically reviews and updates its processes for quantifying the financial results and assets related to our non-U.S. activities.

Non-U.S. revenue in 2016, 2015 and 2014 included $1.05 billion, $938 million and $1.02 billion, respectively, in the U.K., primarily from our London operations.

The following table presents our U.S. and non-U.S. financial results for the periods indicated:
