You are an engineer in a firm and although you're not an accountant, company policy now requires you to sign off on the tax filings for the department you oversee. You've never been a "numbers person and don't fully understand the documents. What do you do?

a) I sign it, figuring that if any problems are found, I can just argue that it's not my fault because I didn't understand the document.

b) I ask someone with more knowledge to walk me through the report before I sign.

c) I sign it, vowing to take an accounting course whenever I find the time.
