For example, I was writing the following sentence:

"Sony donates 5% of profit to good causes."

How can I know that is necessary to use "its" in that sentence, as follows:

"Sony donates 5% of its profit to good causes"

  • Or "...of its profit..." even! – jst345 Apr 26 '17 at 13:20

I would choose a third alternative. Use its. (See What is the best way to explain how to choose between "its" and "it's"?)

Sony donates 5% of its profit to good causes.
