Maybe I'm not getting it right, but how did your employer get the money for the book in the first place, if it's purpose was not actually that of paying the company? Shouldn't the money also be declared as profit for the company this way?
If the company delivered a service, it can pay out the money to a foundation, which can be errected, or maybe the pike foundation itself can be used (if there is any). This way it is not your income, and you have proof of it being transfered to a foundation, although the money is on your account.
