To understand what a "Left Bound Report" might refer to, we need more context.
Could you please provide more information about:
* Where did you encounter this term? (e.g., a document, a website, a software program)
* What is the context surrounding the term? (e.g., what is the document or software program about?)
* What do you think the report might contain?
With more information, I can provide a more specific and helpful answer.
