((B)) the Secretary makes a formal request to the taxpayer for such code and data and to the owner of the computer software source code for such executable code; and

((C)) such code and data is not provided within 180 days of such request.

((B)) the Secretary shall provide, in advance, to the taxpayer and the owner of the software a written list of the names of all individuals who will analyze or otherwise have access to the software;
