Chapter 4:
22. Since the company did not release any new equity, the shareholders’ equity grew solely due
   to retained earnings. Specifically, the retained earnings for the year amounted to:
    Retained earnings = NI – Dividends
    Retained earnings = $29,000 – 6,400
    Retained earnings = $22,600
    As a result, the equity at the end of the year was:
    Ending equity = $153,000 + 22,600
    Ending equity = $175,600
    The ROE based on the end of period equity was:
    ROE = $29,000/$175,600
    ROE = .1651, or 16.51%
    The plowback ratio was:
    Plowback ratio = Addition to retained earnings/NI
    Plowback ratio = $22,600/$29,000
    Plowback ratio = .7793, or 77.93%
    Using the equation presented in the text for the sustainable growth rate, we get:
    Sustainable growth rate = (ROE × b)/[1 – (ROE × b)]
    Sustainable growth rate = [.1651(.7793)]/[1 – .1651(.7793)]
    Sustainable growth rate = .1477, or 14.77%
    The ROE based on the beginning of period equity is
    ROE = $29,000/$153,000
    ROE = .1895, or 18.95%
    Using the shortened equation for the sustainable growth rate and the beginning of period ROE,
    we get:
    Sustainable growth rate = ROE × b
    Sustainable growth rate = .1895 × .7793
    Sustainable growth rate = .1477, or 14.77%
    Using the shortened equation for the sustainable growth rate and the end of period ROE, we get:
    Sustainable growth rate = ROE × b
    Sustainable growth rate = .1651 × .7793
    Sustainable growth rate = .1287, or 12.87%
    When applying the end-of-period Return on Equity (ROE) in the condensed sustainable growth
    rate equation, the resulting growth rate tends to be underestimated. This phenomenon consistently
    arises whenever there is an increase in equity. Specifically, if equity grows, the ROE calculated
    based on the end-of-period equity is lower than the ROE derived from the beginning-of-period
    equity. The abbreviated equation’s ROE (and consequently the sustainable growth rate) relies on
    equity that was not present at the time when net income was earned
23. The ROA using end of period assets is:
    ROA = $29,000/$215,000
    ROA = .1349, or 13.49%
    The beginning of period assets had to have been the ending assets minus the addition to retained
    earnings, so:
    Beginning assets = Ending assets – Addition to retained earnings
    Beginning assets = $215,000 – 22,600
    Beginning assets = $192,400
    And the ROA using beginning of period assets is:
    ROA = $29,000/$192,400
    ROA = .1507, or 15.07%
    Using the internal growth rate equation presented in the text, we get:
    Internal growth rate = (ROA × b)/[1 – (ROA × b)]
    Internal growth rate = [.1349(.7793)]/[1 – .1349(.7793)]
    Internal growth rate = .1175, or 11.75%
    Using the formula ROA × b, and beginning of period assets:
    Internal growth rate = .1507 × .7793
    Internal growth rate = .1175, or 11.75%
    Using the formula ROA × b, and end of period assets:
    Internal growth rate = .1349 × .7793
    Internal growth rate = .1051, or 10.51%
    When applying the end-of-period Return on Assets (ROA) in the condensed internal growth rate
    equation, the resulting growth rate tends to be underestimated. This phenomenon consistently
    arises whenever there is an increase in assets. Specifically, if assets grow, the ROA calculated
    based on the end-of-period assets is lower than the ROA derived from the beginning-of-period
    assets. The abbreviated equation’s ROA (and consequently the internal growth rate) relies on
    assets that were not present at the time when net income was earned
24. Assuming costs vary with sales and a 20 percent increase in sales, the pro forma income
    statement will look like this:
                                           Pro Forma Income Statement
                                      Sales                  $ 823,836
                                      Costs                      665,304
                                      Other expenses              16,824
                                      EBIT                   $ 141,708
                                      Interest                    12,090
                                      Taxable income         $ 129,618
                                      Taxes (21%)                 27,220
                                      Net income             $ 102,398
    The payout ratio is constant, so the dividends paid this year is the payout ratio from last year
    times net income, or:
    Dividends = ($27,475/$83,740)($102,398)
    Dividends = $33,597
    And the addition to retained earnings will be:
    Addition to retained earnings = $102,398 – 33,597
    Addition to retained earnings = $68,801
    The new retained earnings on the pro forma balance sheet will be:
    New retained earnings = $166,705 + 68,801
    New retained earnings = $235,506
    The pro forma balance sheet will look like this:
                                       Pro Forma Balance Sheet
                  Assets                                       Liabilities and Owners’ Equity

             Total                $     149,076             Long-term debt                   $    127,500

                                                                 paid-in surplus             $    105,000
                                                                 Retained earnings                235,506
                                                                       Total                 $    340,506
                                                            Total liabilities and owners’
   Total assets                   $     559,452             equity                           $    545,769
     So the EFN is:
     EFN = Total assets – Total liabilities and equity
     EFN = $559,452– 545,769
     EFN = $13,683
25. First, we need to calculate full capacity sales, which is:
     Full capacity sales = $686,530/.80
     Full capacity sales = $858,163
     The full capacity ratio at full capacity sales is:
     Full capacity ratio = Fixed assets/Full capacity sales
     Full capacity ratio = $341,980/$858,163
     Full capacity ratio = .39850
     The fixed assets required at the projected sales figure is the full capacity ratio times the projected
     sales level:
     Total fixed assets = .39850($823,836) = $328,301
     So, EFN is:
     EFN = ($149,076 + 328,301) – $545,769 = –$68,393
     Note that this solution assumes that fixed assets are decreased (sold) so the company has a 100
     percent fixed asset utilization. If we assume fixed assets are not sold, the answer becomes:
     EFN = ($149,076 + 341,980) – $545,769 = –$54,713
Chapter 27
7. The cost savings before taxes do not impact the decision between leasing and buying, as the
company will undoubtedly utilize the equipment and achieve the savings, regardless of the financing
option chosen. The depreciation tax shield is also a factor to consider:
        Depreciation tax shield = ($8,780,000/5)(.21)
        Depreciation tax shield = $368,760
        And the aftertax lease payment is:
        Aftertax lease payment = $1,950,000(1 – .21)
        Aftertax lease payment = $1,540,500
        The aftertax cost of debt is:
        Aftertax cost of debt = .07(1 – .21)
        Aftertax cost of debt = .0553, or 5.53%
        With these cash flows, the NAL is:
        NAL = $8,780,000 – 1,540,500 – $1,540,500(PVIFA5.53%,4) – $368,760(PVIFA5.53%,5)
        NAL = $270,134.62
        The equipment should be leased.
      To find the maximum payment, we find where the NAL is equal to zero and solve for the
payment. Using X to represent the maximum payment:
        NAL = 0 = $8,780,000 – X(1.0553)(PVIFA5.53%,5) – $368,760(PVIFA5.53%,5)
        X = $1,600,493.57
        So, the maximum pretax lease payment is:
        Pretax lease payment = $1,600,493.57/(1 – .21)
        Pretax lease payment = $2,025,941.23
8.       The after-tax residual value of the asset represents an opportunity cost in the context of the
leasing decision. This value occurs at the end of the system’s life (Year 5). It’s important to note that
the residual value is not akin to a debt-like cash flow, as there is inherent uncertainty associated with it
at Year 0. Despite this uncertainty, in practical terms, we often use the after-tax cost of debt to
discount the residual value. This approach is commonly followed, and we aim to set the Net
Advantage to Leasing (NAL) equal to zero:
       NAL = 0 = $8,780,000 – X(1.0553)(PVIFA5.53%,5) – 368,760(PVIFA5.53%,5) +
900,000/1.05535
       X = $1,753,210.53
        So, the maximum pretax lease payment is:
        Pretax lease payment = $1,753,210.53/(1 – .21)
        Pretax lease payment = $2,219,253.83
9.      The security deposit is a cash outflow at the beginning of the lease and a cash inflow at the
end of the lease when it is returned. The NAL with these assumptions is:
       NAL = $8,780,000 – 600,000 – 1,540,500 – $1,540,500(PVIFA5.53%,4) –
$368,760(PVIFA5.53%,5)
                    + $600,000/1.05535
       NAL = $128,563.07
        With the security deposit, the firm should still lease the equipment rather than buy it, because
the NAL is greater than zero. We could also solve this problem another way. From Problem 7, we
know that the NAL without the security deposit is $270,134.62, so, if we find the present value of the
security deposit, we can add this to $270,134.62. The present value of the security deposit is:
        PV of security deposit = –$600,000 + $600,000/1.05535
        PV of security deposit = –$141,571.55
        So, the NAL with the security deposit is:
        NAL = $270,134.62 – 141,571.55
        NAL = $128,563.07
