 Period  | 
 Cash Flow  | 
 Discounting factor = 1/e^(Rate/2*Y)  | 
 PV of the cash flows = Cash flow x Df  | 
 Weighted cash flow = Period x Cash flow  | 
 Present value of weighted cash flow = Weighted Cash flow x Df  | 
| 
 Y  | 
 CF  | 
 Df = 1/e^(1+5%*Y)  | 
 PV = CF x Df  | 
 WCF = CF x Y  | 
 WPV = WCF x Df  |
