CTC 475 Effect of interest on ATCF
Objective • Know how to develop an ATCF taking into account both depreciation and interest on borrowed money
Tax Concepts • Depreciation is not a cash flow but is needed to determine taxes • Interest on borrowed money is a cash flow and is also needed to determine taxes
Interest • Can finance a project with equity (owner’s funds) or debt (borrowed funds) • If money is borrowed principle and interest must be repaid • Interest is a cash flow and affects taxable income • Principle is a cash flow but does not affect taxable income
Methods for borrowing money • Periodic payment of interest with all principle being repaid at end of repayment period. • Uniform payment of principle. • Uniform payment of (principle and interest). • Pay nothing until end of repayment period.
Example Problem-Method 1-4 • Borrowed amount = $40K • $40K borrowed at 18% per year over 5 years; equal payments • 18% per year compounded annually • Repayment period-5 years
Example Problem-ATCF • Cost Basis = $82K • $42K equity • $40K borrowed at 18% per year over 5 years; equal payments • Salvage Value = $5K • Estimated useful life = 7 years • MARR=15% • Reduction in expenses =$23.5/yr • Depreciate using MACRS-GDS • 5-year property • Determine PW of BTCF & ATCF
PW of BTCF • PW=$17,649 (BTCF) • PW=$3,010 (BTCF-depreciation only and all equity)
Calculate Payment Size • Assume method 3 (uniform payment) • Payment Size, A=$40,000(A/P18,5) • Payment size = $12,792
PW of ATCF • Must take each year back to zero (no series because each year has a different number) • PW=-$42K+$10,743(P/F15,1)+$13,746(P/F15,2) +$9,774(P/F15,3)+$7,156(P/F15,4) +$5,695(P/F15,5)+$17,116(P/F15,6) +$15,510(P/F15,7)+$3,300(P/F15,7) • PW of ATCF=$6,010 (cost effective and higher than if company had funded 100% with equity)
ATCF’s are impacted by: • Depreciation methods • Recovery period • Planning horizon • Different tax rates • Interest rates on borrowed money
