A deliberately year-specific scope
The manual is anchored to 2011 plan years, and that anchor is its defining feature. Rules and forms are presented as they stood for that filing period, which makes the book precise for its purpose and unsuitable as a guide to later years. Readers are expected to know which version they need.
- Scope is fixed to 2011 plan years
- Precision comes from the narrow period
- Later filing years need other references
