Description: Internal Revenue Code (I.R.C.) §§243–2461 provide that a corporation is allowed a percentage deduction for dividends received from other corporations (the DRD). In addition to the general corporate rules regarding the DRD, if the recipient of a corporate dividend is a life insurance company, I.R.C. §812(a) further allocates the benefit of the DRD between the company’s share and the policyholders’ share. This allocation methodology is often referred to as proration. Proration has historically involved a complex and at times contentious2 formulaic process.
