Agreement between the United States of America and Switzerland on the request for information from the Internal Revenue Service regarding UBS

What is it about?

The Agreement on the request for information from the Internal Revenue Service (IRS) regarding UBS resolves the conflict over sovereignty with the USA along the lines provided for in the Tax Treaty.
