What you have to do is put into context the amount of donation. You have to relate the donation amount to the company's annual net income (what percentage do these donations/programs represent the company's yearly profits?).
You can also compare the company’s donation to the overall donations for the specific cause. This will show how much the monetary contribution has helped. This can help readers better understand the scope of these initiatives (i.e. is it marginal or quite large).
One-offs donations should not make the subject of an analysis. They do not portray the real or current impact of the company.
