Please someone help me. I am lost.

I am a director of a company's branch in Singapore. The company's hq is located at Japan itself.

I've been working for decades in the company already and am unsure of the nature of the crime.

So this is how it goes, i have been for a few years working on the sidelines earning extra cash in the company's name but for my own benefit.

Recently, i've been caught and admitted my mistakes and 'crimes' during the HQ meeting in Japan.

I have also submitted all of the documents that have documented my transaction with other outside companies.

The question is, what nature of crime have i committed and whats the maximum punishment i could get.

It is because, i heard that i could get a jail term for that besides making compensation of all the profits i have earned.

Please advice me someone. I am desperate.
