I am trying to figure out the calculation for "Add back interest on bonds, net of income tax" using this information: Potentially Dilutive Securities Peyton has the following potential dilutive securities: $4,000,000 in bonds payable 10%, 20 year. Every $1,000 bond can convert to 5 shares of common stock. Preferred stockEvery share issued can convert to 1 share of common stock.

table {mso-displayed-decimal-separator:"\."; mso-displayed-thousand-separator:"\,";} tr {mso-height-source:auto;} col {mso-width-source:auto;} td {padding-top:1px; padding-right:1px; padding-left:1px; mso-ignore:padding; color:black; font-size:11.0pt; font-weight:400; font-style:normal; text-decoration:none; font-family:Calibri, sans-serif; mso-font-charset:0; text-align:general; vertical-align:bottom; border:none; white-space:nowrap; mso-rotate:0;} .xl18 {font-size:12.0pt; font-family:Arial, sans-serif; mso-font-charset:0;} .xl40 {font-size:12.0pt; font-family:Arial, sans-serif; mso-font-charset:0;} .xl161 {font-size:12.0pt; font-weight:700; font-family:Arial, sans-serif; mso-font-charset:0; text-align:center; white-space:normal;}
