In the Criminal Investigation (CI) annual Report for the fiscal year 2015 the Internal Revenue Service (IRS) mentioned the US Tax Program for Swiss Banks on page 1:

The Swiss Bank program continued to provide solid leads and information that we are using to develop other cases around the world. Bank Leumi admitted to assisting U.S. taxpayers in hiding assets in offshore bank accounts, disclosed more than 1,500 U.S. account holders and agreed to pay a total of $270 million. This was the first time an Israeli bank has admitted to such criminal conduct.
