I don't get any profit, all is distributed to investors

I don't suppose you are one of the investors are you?

As for you not understanding what I mean, as you say above, did you decide to donate 20% after asking your customers and investors whether they agree, or did you decide on your own?

I have learnt, from real life, that the corps who make the largest donations to some charity or other, are the worst and most inhumane ones, so I tend to take such disclosures with a pinch of salt.

Okay, so you are doing it out of the goodness of your heart! Unbelievable that you would devote so much of your life to doing good without any reward for you - but I'll be a nice guy and buy it.
