what is the difference between ex gratia and compensation
Ex gratia Ex gratia (/ˌɛks ˈɡreɪʃiə/;[1] also spelled ex-gratia) is Latin for "by favour", and is most often used in a legal context. When something has been done ex gratia, it has been done voluntarily, out of kindness or grace. In law, an ex gratia payment is a payment made without the giver recognising any liability or legal obligation.
Defined benefit pension plan A defined benefit plan is 'defined' in the sense that the benefit formula is defined and known in advance. Conversely, for a "defined contribution retirement saving plan", the formula for computing the employer's and employee's contributions is defined and known in advance, but the benefit to be paid out is not known in advance.[2]
