Letter from George Bertram to Mr. Jim Cousins, dated May 1998:As Chief Executive of the Contributions Agency I have responsibility for answering questions about matters relating to the Contributions Agency. I have been asked to reply to your question about the Yield Analysis and Statistical System (YASS) and its use within the Agency's regions and regional offices.The YASS is a personal computer based targeting system that has been rolled out for use by the Contributions Agency's Operations in the Field. Initially, one YASS personal computer was installed into each region, but subsequently nine of the twelve regions have installed additional YASS personal computers.YASS is a targeting and modelling tool that was designed to assist CA Field Operations in identifying those employers who:
- Need assistance in completing their end of year returns correctly; or
- Those that are most likely to owe arrears of National Insurance ContributionsYASS uses data taken from the Agency's Employers Index System (ENDX) and information supplied from the inspections of employers National Insurance records.
