The majority of our business is in the United States. Revenue from foreign projects and offices was 26%, 23% and 25% of total revenue for the years ended September 30, 2015, 2014 and 2013, respectively. In the year ended September 30, 2015, approximately 50% of our total revenue was derived from state government agencies, many of whose programs received significant federal funding, 22% from foreign government agencies, 20% from U.S.-based Federal Government agencies, and 8% from other sources including local municipalities and commercial customers. We believe that the credit risk associated with our receivables is limited due to the credit worthiness of these customers. During fiscal year 2015, the U.S. Federal Government and the state of New York each provided more than 10% of our annual revenue. Revenue from the U.S. Federal Government was exclusively within the U.S. Federal Segment. Revenue from the state of New York was exclusively within our Health Services Segment.
