Non-U.S. Activities

We generally define our non-U.S. activities as those revenue-producing business activities that arise from clients domiciled 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.

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



	Three Months Ended March 31, 2016						Three Months Ended March 31, 2015

Income before income taxes	176		254		430		342		157		499

Non-U.S. assets were $81.6 billion and $67.7 billion as of March 31, 2016 and 2015, respectively.
