The Business Cycle Facts (continued)
Two important characteristics of the cyclical behaviour:
the direction in which a macroeconomic variable moves relative to the direction of aggregate economic activity; the timing of the variable’s turning points relative to the turning points of the business cycle.

The Business Cycle Facts (continued)
A leading variable’s turning points occur before those of the business cycle. A coincident variable’s turning points occur around the same time as those of the business cycle. A lagging variable’s turning points occur later than those of the business cycle.

The property of catch-up is called convergence. If there is not convergence, countries that start off poor are likely to remain poor. The Solow model makes predictions about when convergence should occur. According to the model, whether two economies will converge depends on why they differ in the first place (i.e., savings rates, population growth rates, and human capital accumulation).

What are financial futures contracts? Which financial institutions use futures and other derivatives for risk management?Financial futures contacts are contracts calling for the delivery of specific types of securities at a set price on a specific future date. Financial futures contract help to hedge interest rate risk and are thus, used by any bank or financial institution that is subject to interest rate risk.8-2. How can financial futures help financial service firms deal with interest-rate risk?Financial futures allow banks and other financial institutions to deal with interest-rate risk by reducing risk exposure from unexpected price changes. The financial futures markets are designed to shift the risk of interest rate fluctuations from risk-averse investors to speculators willing to accept and possibly profit from such risks.8-3. What is a long hedge in financial futures? A short hedge?A long hedger offsets risk by buying financial futures contracts around the time new deposits are expected, when a loan is to be made, or when securities are added to the bank's portfolio. Later, as deposits and loans approach maturity or securities are sold, a like amount of futures contracts is sold. A short hedger offsets risk by selling futures contracts when the bank is expecting a large cash inflow in the near future. Later, as deposits come flowing in, a like amount of futures contracts is purchased.8-4. What futures transactions would most likely be used in a period of rising interest rates? Falling interest rates?Rising interest rates generally call for a short hedge, while falling interest rates usually call for some form of long hedge.8-5. How do you interpret the quotes for financial futures in The Wall Street Journal?106The first column gives you the opening price, the second and third the daily high and low price, respectively. The fourth column shows the settlement price followed by the change in the settlement price from the previous day. The next two columns show the historic high and low price and the last column points out the open interest in the contract.8-6. A futures is currently selling at an interest yield of 4 percent, while yields currently stand at 4.60 percent. What is the basis for these contracts?The basis for these contracts is currently 4.60% – 4% or 60 basis points.8-7. Suppose a bank wishes to sell $150 million in new deposits next month. Interest rates today on comparable deposits stand at 8 percent, but are expected to rise to 8.25 percent next month. Concerned about the possible rise in borrowing costs, management wishes to use a futures contract. What type of contract would you recommend? If the bank does not cover the interest rate risk involved, how much in lost potential profits could the bank experience?At an interest rate of 8 percent:= $1 million$150 million x 0.08 x 30360At an interest rate of 8.25 percent:$150 million x 0.0825 x 30= $1.031 million360The potential loss in profit without using futures is $0.0313 million or $31.3 thousand. In this case the bank should use a short hedge.8-8. What kind of futures hedge would be appropriate in each of the following situations?a. A financial firm fears that rising deposit interest rates will result in losses on fixed-rateloans?b. A financial firm holds a large block of floating-rate loans and market interest rates arefalling?c. A projected rise in market rates of interest threatens the value of the financial firm’sbond portfolio?a. The rising deposit interest rates could be offset with a short hedge in futures contracts (for example, using Eurodollar deposit futures).b. Falling interest yields on floating-rate loans could be at least partially offset by a long hedge in Treasury bonds.107c. The bank's bond portfolio could be protected through appropriate short hedges using Treasury bond and note futures contracts.8-9. Explain what is involved in a put option?A put option allows its holder to sell securities to the option writer at a specified price. The buyer of a put option expects market prices to decline in the future or market interest rates to increase. The writer of the contract expects market prices to stay the same or rise in the future.8-10. What is a call option?A call option permits the option holder to purchase specific securities at a guaranteed price from the writer of the option contract. The buyer of the call option expects market prices to rise in the future or expects interest rates to fall in the future. The writer of the contract expects market prices to stay the same or fall in the future.8-11. What is an option on a futures contract?An option on a futures contract does not differ from any other kind of option except that the underlying asset is not a security, but a futures contract.8-12. What information do T-bond and Eurodollar futures option quotes contain?The quotes contain information about the strike prices and the call and put prices at each different strike price for given months.8-13. Suppose market interest rates were expected to rise? What type of option would normally be used?If interest rates were expected to rise, a put option would normally be used. A put option allows the option holder to deliver securities to the option writer at a price which is now above market and make a profit.8-14. If market interest rates were expected to fall, what type of option would a financial institution’s manager be likely to employ?If interest rates were expected to fall, a call option would likely be employed. When interest rates fall, the market value of a security increases. The security can then be purchased at the option price and sold at a profit at the higher market price.8-15. What rules and regulations have recently been imposed on the use of futures, options, and other derivatives? What does the Financial Accounting Standards Board (FASB) require publicly traded firms to do in accounting for derivative transactions?108Each bank has to implement a proper risk management system comprised of (1) policies and procedures to control financial risk taking, (2) risk measurement and reporting systems and (3) independent oversight and control processes. In addition, FASB introduced statement 133 which requires that all derivatives are recorded on the balance sheet as assets or liabilities at their fair value. Furthermore, the change in the fair value of a derivative and a fair value hedge must be reflected on the income statement.8-16. What is the purpose of an interest rate swap?The purpose of an interest rate swap is to change an institution's exposure to interest rate fluctuations and achieve lower borrowing costs.8-17. What are the principal advantages and disadvantages of rate swaps?The principal advantage of an interest-rate swap is the reduction of interest-rate risk of both parties to the swap by allowing each party to better balance asset and liability maturities and cash-flow patterns. Another advantage of swaps is that they usually reduce interest costs for one or both parties to the swap. The principal disadvantage of swaps is they may carry substantial brokerage fees, credit risk and some basis risk.8-18. How can a financial institution get itself out of a swap agreement?The usual way to offset an existing swap is to undertake another swap agreement with opposite characteristics.8-19. How can financial-service providers make use of interest rate caps, floors, and collars to generate revenue and help manage interest rate risk?Banks and other financial institutions can generate revenue by charging up-front fees for interest rate caps on loans and interest rate floors on securities. In addition, a positive net premium on interest rate collars will add to a bank's fee income. Caps, floors, and collars help manage interest rate risk by setting maximum and minimum interest rates on loans and securities. They allow the lender and borrower to share interest rate risk.8-20. Suppose a bank enters into an agreement to make a $10 million, three-year floating-rate loan to one of its corporate customers at an initial rate of 8 percent. The bank and the customer agree to a cap and a floor arrangement in which the customer reimburses the bank if the floating loan rate drops below 6 percent and the bank reimburses the customers if the loan rate rises above 10 percent. Suppose that, at the beginning of the loan's second year, the floating loan rate drops to 4 percent for a year and then, at the beginning of the third year, the loan rate increases to 11 percent for the year. What rebates must be paid by each party to the agreement?The rebate owed by the bank for the third year must be:(11%-10%) x $10 million = $100,000.109The rebate that must be forwarded to the bank for the second year must be:(6%-4%) x $10 million = $200,000.Problems8-1. You hedged your bank’s exposure to declining interest rates by buying one March Treasury bond futures contract at the opening price on November 21, 2005(see exhibit 8-2). It is now January 9, and you discover that on Friday, January 6 March T-bond futures opened at 113-17 and settled at 113-16.a. What are the profits/losses on your long position as of settlement on January 6?Buy at 112-06 or 112 6/32 per contract = 112,187.50Value at settlement on January 6, 113-16 or 113 16/32 = 113,500.Gain = 113,500 – 112,187.50 = $1312.50b. If you deposited the required initial margin on 11/21 and have not touched theequity account since making that cash deposit, what is your equity accountbalance?The equity account balance will increase by the gain in the position,thus $1,150 + $1312.50 = $2,462.508-2 Use the quotes of Eurodollar futures contracts traded on the Chicago Mercantile Exchange on December 20, 2005 to answer the following questions:a. What is the annualized discount yield based on the low IMM index for the nearestJune contract?The annualized discount yield is 100 – 95.13 = 4.87 percentb. If your bank took a short position at the high price for the day for 15 contracts, whatwould be the dollar gain or loss at settlement on December 20, 2005?Sell at high price: (1,000,000x[1-((4.87/100)x90/360)]x15 = 14,817,375Value at settlement: (1,000,000x[1-((4.86/100)x90/360)]x15 = 14,817,750Loss: 14,817,375 – 14,817,750 = -$375c. If you deposited the initial required hedging margin in your equity account upontaking the position described in b, what would be the marked to market value ofyour equity account at settlement?Initial margin = $700x15 = $10,500110You realize a $375 loss for this transaction.Thus your equity position is: $10,500 - $375 = $10,1258-3. What kind of futures or options hedges would be called for in the following situations?a. Market interest rates are expected to increase and First National Bank’s asset andliability managers expect to liquidate a portion of their bond portfolio to meetdepositor’s demands for funds in the upcoming quarter.First National can expect a lower price when they sell their bond portfolio unless it uses short futures hedges in which contracts for government securities are first sold and then purchased at a profit as security prices fall provided interest rate really do rise as expected. A similar gain could be made using put options on government securities or on financial futures contracts.b. Silsbee Savings Bank has interest-sensitive assets of $79 million and interest-sensitive liabilities of $88 million over the next 30 days and market interest rates are expected to rise. Silsbee Savings Bank’s interest-sensitive liabilities exceed its interest-sensitive assets by $11 million which means the bank will be open to losses if interest rates rise. The bank could sell financial futures contracts or use a put option on government securities or financial futures contracts approximately equal in dollar volume to the $11 million interest-sensitive gap to hedge their risk.c. A survey of Tuskee Bank’s corporate loan customers this month (January) indicates that, on balance, this group of firms will need to draw $165 million from their credit lines in February and March, which is $65 million more than the bank’s management has forecasted and prepared for. The bank’s economist has predicted a significant increase in money market interest rates over the next 60 days.The forecast of higher interest rates means the bank must borrow at a higher interest cost which, other things held equal, will lower its net interest margin. To offset the expected higher borrowing costs the bank's management should consider a short sale of financial futures contracts or a put option approximately equal in volume to the additional loan demand. Either government securities or EuroCDs would be good instruments to consider using in the futures market or in the option market.d. Monarch National Bank has interest-sensitive assets greater than interest sensitive liabilities by $24 million. If interest rates fall (as suggested by data from the Federal Reserve Board) the bank’s net interest margin may be squeezed due to the decrease in loan and security revenue.Monarch National Bank has interest-sensitive assets greater than interest-sensitive liabilities by $24 million. If interest rates fall, the bank's net interest margin will likely be squeezed due to the faster fall in interest income. Purchases of financial futures contracts followed by a subsequent sale or call options would probably help here.111e. Caufield Thrift Association finds that its assets have an average duration of 1.5 years and its liabilities have an average duration of 1.1 years. The ratio of liabilities to assets is .90. Interest rates are expected to increase by 50 basis points during the next six months.Caufield Bank and Trust Company has asset duration of 1.5 years and a liabilities duration of 1.1.A 50-basis point rise in money-market rates would reduce asset values relative to liabilities which mean its net worth would decline. The bank should consider short sales of government futures contracts or put options on these securities or on their related futures contracts.8-4. Your bank needs to borrow $300 million by selling time deposits with 180-day maturities. If interest rates on comparable deposits are currently at 4 percent, what is the cost of issuing these deposits? Suppose deposit interest rates rise to 5 percent. What then will be the marginal cost of these deposits? What position and types of futures contract could be used to deal with this cost increase?At a rate of 4 percent the interest cost is:$300 million x 0.04 x 180= $6,000,000360At a rate of 5 percent the interest cost would be:= $7,500,000$300 million x 0.05 x 180360A short hedge could be used based upon Eurodollar time deposits.8-5. In response to the above scenario, management sells 300, 90-day Eurodollar time deposits futures contracts trading at an IMM Index of 98. Interest rates rise as anticipated and your bank offsets its position by buying 300 contracts at an IMM index of 96.98. What type of hedge is this? What before-tax profit or loss is realized from the futures position?Bank sells Eurodollar futures at (1,000,000*[1-((2/100)*90/360)] $995,000 (per contract)Bank buys Eurodollar futures at (1,000,000*[(1-(3.02/100)*90/360]$992,450 (per contract) Expected Before-tax Profit $ 2,550 (per contract)And Total Profit would be 300*$2550 = $765,000In this case the bank has employed a short hedge which partially offsets the higherborrowing costs outlined above.8-6. It is March and Cavalier Financial Services Corporation is concerned about what an increase in interest rates will do to the value of its bond portfolio. The portfolio currently has a market value of $101.1 million and Cavalier’s management intends to liquidate $1.1 million in bonds in June to fund additional corporate loans. If interest rates increase to 6 percent, the bond will sell for $1 million with a loss of $100,000. Cavalier’s management sells 10 June Treasury bond contracts at 109-05 in March. Interest rates do increase, and in June Cavalier’s ma nagement offsets its position by buying 10 June Treasury bond contracts at 100-03.112113a.What is the dollar gain/loss to Cavalier from the combined cash and futures market operations described above?Loss on cash transaction: $100,000Gain on futures transaction: 109,156.25 – 100,093.75 = 9062.5 (per contract)Loss: 9062.50(10) – 100,000 = -$9,375b. What is the basis at the initiation of the hedge?110,000 – 109,156.25 = 843.75c. What is the basis at the termination of the hedge?100,000 – 100,093.75 = -93.75d. Illustrate how the dollar return is related to the change in the basis from initiationfrom termination?Dollar return = -93.75 – 843.75 = -937.50 per contract or –937.50(10) = -$93758-7. By what amount will the market value of a Treasury bond futures contract change ifinterest rates rise from 5 to 6 percent? The underlying Treasury bond has a duration of 10.48 years and the Treasury bond futures contract is currently quoted at 113-06 (Remember that Treasury bonds are quoted in 32nds)Change in value = -10.48 x $113,187.50 x .01/(1+.05) = -$11,297.198-8. Trojan National Bank reports that its assets have a duration of 8 years and its liabilities average 3 years in duration. To hedge this duration gap, management plans to employ Treasury bond futures, which are currently quoted at 112-17 and have a duration of 10.36 years. Trojan ’s latest financial report shows total assets of $120 million and liabilities of $97 million.Approximately how many futures contracts will the bank need to cover its overall exposure?Number of Futures Contracts Needed = 25.531,112*36.10000,000,120*]3*120978[ = 5748-9 You hedged your bank’s exposure to declining interest rates by buying one March call on Treasury bond futures at the premium quoted on December 13th , 2005 (see exhibit 8-4).a. How much did you pay for the call in dollars if you chose the strike price of 110?(Remember that option premiums are quoted in 64ths.)Price per call = 2.625 x 100,000 = $262,500b. Using the following information for trades on December 21, 2005, if you sold thecall on 12/21/05 due to a change in circumstances would you have reaped a profitor loss? Determine the amount of the profit/loss.Sell call at: 3.125 x 100,000 = 312,500Gain = 312,500 – 262,500 = $50008-10 Refer to the information given for problem 9. You hedged your bank’s exposure to increasing interest rates by buying one March put on Treasury bond futures at the premium quoted on December 13th, 2005 (see exhibit 8-4).a. How much did you pay for the put in dollars if you chose the strike price of 110?(Remember that premiums are quoted in 64ths.)Price per put = .765625 x 100,000 = $76,562.25b. Using the above information for trades on December 21, 2005, if you sold the puton 12/21/05 due to a change in circumstances would you have reaped a profit orloss? Determine the amount of the profit/loss.Sell put at: .421875 x 100,000 = $42,187.50Loss = $42,187.50 – 76,562.25 = -$34,374.758-11. You hedged your thrift institution’s exposure to dec lining interest rates by buying one March call on Eurodollar deposits futures at the premium quoted on December 13th, 2005 (see exhibit 8-4).a. How much did you pay for the call in dollars if you chose the strike price of 9525?(remember that premiums are quoted in IMM index terms)Value of the call: 6.25 x $25 = $156.25b. If March arrives and Eurodollar Deposit Futures have a settlement index atexpiration of 96.00, what is your profit or loss? (Remember to include the premiumpaid for the call option).Payout from settlement: (9600-9525) 75 basis points x $25 = $1,875Net gain: $1,875 –$156.25 = $1,718.758-12. You hedged your bank’s exposure to increasing interest rates by buying one March put on Eurodollar deposit futures at the premium quoted on December 13th, 2005 (see exhibit 8-4).a. How much did you pay for the put in dollars if you chose the strike price of 9,550?(remember that premiums are quoted in IMM index terms)114Value of the put: 29.25 x $25 = $731.25b. If March arrives and Eurodollar Deposit Futures have a settlement index atexpiration of 96.00, what is your profit or loss? (Remember to include the premiumpaid for the put option).Payout from settlement: $0 (option is out of the money)Net loss: $0 - $731.25 = -$731.258-13. A bank is considering the use of options to deal with a serious funding cost problem. Deposit interest rates have been rising for six months, currently averaging 5 percent, and are expected to climb as high as 6.75% over the next 90 days. The bank plans to issue $60 million in new money market deposits in about 90 days. It can buy put or call options on 90 day Eurodollar time deposit futures contracts for a quoted premium of .31 or $775 for each million-dollar contract. The strike price is quoted as 9,500. We expect the futures to trade at an index of 93.50 within 90 days. What kind of option should the bank buy? What before tax profit could the bank earn for each option under the terms described?You are trying to protect the bank against rising interest rates, thus you want to buy a put option. Profit on put: payout from settlement = (9500-9350) 150 basis points x $25 = $3,750Net profit: $3,750 - $775 = $2,975If the bank bought the call option, the value at settlement would be $0 and the bank would loose the call premium of $775.8-14. Hokie Savings Bank wants to purchase a portfolio of home mortgage loans with an expected average return of 8.5 percent. The bank’s management is concerned that interest rates will drop and the cost of the portfolio will increase from the current price of $50 million. In six months when the funds become available to purchase the loan portfolio, market interest rates are expected to be in the 7.5 percent range. Treasury bond options are available today at a quoted price of $79,000 (per $100,000 contract), upon payment of a $700 premium, and are forecast to rise to a market value of $87,000 per contract. What before-tax profits could the bank earn per contract on this transaction? How many options should Hokie buy?Profit per contract: $87,000 - $79,000 -$700 = $7,300Hokie should buy enough options to offset the increase in the price of the loan portfolio. Thus, figure out the price increase and divide that number by 7,300 to get the number of options needed. 8-15. A savings and loan’s credit rating has just slipped, and half of its assets are long term mortgages. It offers to swap interest payments with a money-center bank in a $100 million deal. The bank can borrow short term at LIBOR (8.05 percent) and long term at 8.95 percent. The S&L must pay LIBOR plus 1.5 percent on short term debt and 10.75 percent on long term debt. Show how these parties could put together a swap deal that benefits both of them about equally.115This SWAP agreement would have the form:Fixed Rate the Floating Rate PotentialBorrower Pays the Borrower Interest-Rateif They Issue Pays on Short- SavingsLong-Term Bonds Term Loans of Each BorrowerS&L 10.75% LIBOR + 1.50% 1.20%Money- 8.95% LIBOR (8.05%) 0.90%Center BankDifference 1.80% 1.50% 0.30%in Rates Due toDifferences inCredit RatingsIf the money-center bank borrows long-term at 8.95 percent and the S&L at LIBOR + 1.50 percent (which is currently 8.05 + 1.50 or 9.55 percent) and they exchange interest payments, both would save if the S&L agreed to pay a portion of the bank’s basic borrowing rate. For example, the S&L could pay 160 basis points to the bank which would more than cover the difference. After the exchange in payments and basis points the S&L would pay 8.95% +1.6% or 10.55% which is lower than the S&L’s long term rate and the bank would pay 9.55%-1.6% or 7.95% which is less than the bank’s short term rate and each party would get the type of payment they want.8-16. A bank plans to borrow $55 million in the money market at a current interest rate of 4.5 percent. However, the borrowing rate will float with market conditions. To protect itself the bank has purchased an interest-rate cap of 5 percent to cover this borrowing. If money market interest rates on these funds suddenly climb to 5.5 percent as the borrowing begins, how much in total interest will the bank owe and how much of an interest rebate will it receive assuming the borrowing is only for one month?Total Amount Interest Number of Months Interest Owed = Borrowed * Rate Charged * 12= $55 million x 0..055 x 112= $0.527 million or $252,083.33.How much of an interest rebate will the bank receive for its one-month borrowing?116[]12MonthsofNumberxBorrowedAmt.xRateCap-RateInterestMarketRebateInterest == (.055 - .05) x $55 million x 112= $22,916.67.8-17.

In return for granting Fairhills an interest cap of 8% on its loan, this thrift has received from this customer a floor rate on the loan of 6 percent. Suppose that, as the loan is about to start the prime rate declines to 5.25 percent and remains there for the duration of the loan. How much (in dollars) will Fairhill Farms have to pay in total interest on this six month loan?

财务报表分析(英文版)答案
Chapter 8Return On Invested Capital And Profitability AnalysisReturn on invested capital is important in our analysis of financial statements. Financial statement analysis involves our assessing both risk and return. The prior three chapters focused primarily on risk, whereas this chapter extends our analysis to return. Return on invested capital refers to a company's earnings relative to both the level and source of financing. It is a measure of a company's success in using financing to generate profits, and is an excellent measure of operating performance. This chapter describes return on invested capital and its relevance to financial statement analysis. We also explain variations in measurement of return on invested capital and their interpretation. We also disaggregate return on invested capital into important components for additional insights into company performance. The role of financial leverage and its importance for returns analysis is examined. This chapter demonstrates each of these analysis techniques using financial statement data.•Importance of Return on Invested CapitalMeasuring Managerial EffectivenessMeasuring ProfitabilityMeasuring for Planning and Control •Components of Return on Invested CapitalDefining Invested CapitalAdjustments to Invested Capital and IncomeComputing Return on Invested Capital•Analyzing Return on Net Operating AssetsDisaggregating Return on Net Operating AssetsRelation between Profit Margin and Asset TurnoverProfit Margin AnalysisAsset Turnover Analysis•Analyzing Return on Common EquityDisaggregating Return on Common EquityFinancial Leverage and Return on Common EquityAssessing Growth in Common Equity•Describe the usefulness of return measures in financial statement analysis. •Explain return on invested capital and variations in its computation.•Analyze return on net operating assets and its relevance in our analysis. •Describe disaggregation of return on net operating assets and the importance of its components.•Describe the relation between profit margin and turnover.•Analyze return on common shareholders' equity and its role in our analysis. •Describe disaggregation of return on common shareholders' equity and the relevance of its components.•Explain financial leverage and how to assess a company's success in trading on the equity across financing sources.1. The return that is achieved in any one period on the invested capital of a companyconsists of the returns (and losses) realized by its various segments and divisions. In turn, these returns are made up of the results achieved by individual product lines and projects. A well-managed company exercises rigorous control over the returns achieved by each of its profit centers, and it rewards the managers on the basis of such results. Specifically, when evaluating new investments in assets or projects, management will compute the estimated returns it expects to achieve and use these estimates as a basis for its decision to invest or not.2. Profit generation is the first and foremost purpose of a company. The effectiveness ofoperating performance determines the ability of the company to survive financially, to attract suppliers of funds, and to reward them adequately. Return on invested capital is the prime measure of company performance. The analyst uses it as an indicator of managerial effectiveness, and/or a measure of the company's ability to earn a satisfactory return on investment.3. If the investment base is defined as comprising net operating assets, then netoperating profit (e.g., before interest) after tax (NOPAT) is the relevant income figure to use. The exclusion of interest from income deductions is due to its being regarded asa payment for the use of money from the suppliers of debt capital (in the same waythat dividends are regarded as a payment to suppliers of equity capital). NOPAT is the appropriate amount to measure against net operating assets as both are considered to be operating.4. First, the motivation for excluding nonproductive assets from invested capital isbased on the idea that management is not responsible for earning a return on non-operating invested capital. Second, the exclusion of intangible assets from the investment base is often due to skepticism regarding their value or their contribution to the earning power of the company. Under GAAP, intangibles are carried at cost.However, if their cost exceeds their future utility, they are written down (or there will be an uncertainty exception regarding their carrying value in the auditor's opinion).The exclusion of intangible assets from the asset base must be based on more substantial evidence than a mere lack of understanding of what these assets represent or an unsupported suspicion regarding their value. This implies that intangible assets should generally not be excluded from invested capital.5. The basic formula for computing the return on investment is net income divided bytotal invested capital. Whenever we modify the definition of the investment base by, say, omitting certain items (liabilities, idle assets, intangibles, etc.) we must also adjust the corresponding income figure to make it consistent with the modified asset base.6. The relation of net income to sales is a measure of operating performance (profitmargin). The relation of sales to total assets is a measure of asset utilization or turnover—a means of determining how effectively (in terms of sales generation) the assets are utilized. Both of these measures, profit margin as well as asset utilization,determine the return realized on a given investment base. Sales are an important factor in both of these performance measures.7. Profit margin, although important, is only one aspect of the return on invested capital.The other is asset turnover. Consequently, while Company B's profit margin is high, its asset turnover may have been sufficiently depressed so as to drag down the overall return on invested capital, leading to the shareholder's complaint.8. The asset turnover of Company X is 3. The profit margin of Company Y is 0.5%. Sinceboth companies are in the same industry, it is clear that Company X must concentrate on improving its asset turnover. On the other hand, Company Y must concentrate on improving its profit margin. More specific strategies depend on the product and industry.9. The sales to total assets (asset turnover) component of the return on invested capitalmeasure reflects the overall rate of asset utilization. It does not reflect the rate of utilization of individual asset categories that enter into the overall asset turnover. To better evaluate the reasons for the level of asset turnover or the reasons for changes in that level, it is helpful to compute the rate of individual asset turnovers that make up the overall turnover rate.10. The evaluation of return on invested capital involves many factors. Theinclusion/exclusion of extraordinary gains and losses, the use/nonuse of trends, the effect of acquisitions accounted for as poolings and their chance of recurrence, the effect of discontinued operations, and the possibility of averaging net income are justa few of many such factors. Moreover, the analyst must take into account the effectsof price-level changes on return calculations. It also is important that the analyst bear in mind that return on invested capital is most commonly based on book values from financial statements rather than on market values. And finally, many assets either do not appear in the financial statements or are significantly understated. Examples of such assets are intangibles such as patents, trademarks, research and development activities, advertising and training, and intellectual capital.11. The equity growth rate is calculated as follows:[Net income – Preferred dividends – Common dividend payout] / Average common equity.This is the growth rate due to the retention of earnings and assumes a constant dividend payout over time. It indicates the possibilities of earnings growth without resort to external financing. The resulting increase in equity can be expected to earn the rate of return that the company earns on its assets and, thus, further contribute to growth in earnings.12. a. The return on net operating assets and the return on common stockholders' equitydiffer by the capital investment base (and its corresponding effects on net income).RNOA reflects the return on the net operating assets of the company whereas ROCE reflects the perspective of common shareholders.b. ROCE can be disaggregated into the following components to facilitate analysis:ROCE = RNOA + Leverage x Spread. RNOA measures the return on net operating assets, a measure of operating performance. The second component (Leverage x Spread) measures the effects of financial leverage. ROCE is increased by adding financial leverage so long as RNOA>weighted average cost of capital. That is, if the firm can earn a return on operating assets that is greater than the cost of the capital used to finance the purchase of those assets, then shareholders are better off adding debt to increase operating assets.13. a. ROCE can be disaggregated as follows:equitycommon Av erage Sales Sales div idends Preferred - income Net ⨯ This shows that “equity turnover” (sales to average common equity) is one of the two components of the return on common shareholders' equity. Assuming a stable profit margin, the equity turnover can be used to determine the level and trend of ROCE. Specifically, an increase in equity turnover will produce an increase in ROCE if the profit margin is stable or declines less than the increase in equity turnover. For example, a common objective of discount stores is to lower prices by lowering profit margins, but to offset this by increasing equity turnover by more than the decrease in profit margin.b. Equity turnover can be rewritten as follows:equitycommon Av erage assets operating Net assets operating Net Sales ⨯ The first factor reflects how well net operating assets are being utilized. If the ratio is increasing, this can signal either a technological advantage or under-capacity and the need for expansion. The second factor reflects the use of leverage. Leverage will be higher for those firms that have financed more of their assets through debt. By considering these factors that comprise equity turnover, it is apparent that EPS cannot grow indefinitely from an increase in these factors. This is because these factors cannot grow indefinitely. Even if there is a technological advantage in production, the sales to net operating assets ratio cannot increase indefinitely. This is because sooner or later the firm must expand its net operating asset base to meet rising sales or else not meet sales and lose a share of the market. Also, financing new assets with debt can increase the net operating assets to common equity ratio. However, this can only be pursued to a point —at which time the equity base must expand (which decreases the ratio).14. When convertible debt sells at a substantial premium above par and is clearly held byinvestors for its conversion feature, there is justification for treating it as the equivalent of equity capital. This is particularly true when the company can choose at any time to force conversion of the debt by calling it in.Exercise 8-1 (35 minutes)a. First alternative:NOPAT = $6,000,000 * 10% = $600,000Net income = $600,000 – [$1,000,000*12%](1-.40) = $528,000Second alternative:NOPAT = $6,000,000 * 10% = $600,000Net income = $600,000 – [$2,000,000*12%](1-.40) = $456,000b. First alternative:ROCE = $528,000 / $5,000,000 = 10.56%Second alternative:ROCE = $456,000 / $4,000,000 = 11.40%c. First alternative:Assets-to-Equity = $6,000,000 / $5,000,000 = 1.2Second alternative:Assets-to-Equity = $6,000,000 / $4,000,000 = 1.5d. First, let’s compute return on assets (R NOA):First alternative: $600,000 / $6,000,000 = 10%Second alternative: $600,000 / $6,000,000 = 10%Second, notice that the interest rate is 12% on the debt (bonds). More importantly, the after-tax interest rate is 7.2% (12% x (1-0.40)), which is less than RNOA. Hence, the company earns more on its assets than it pays for debt on an after-tax basis. That is, it can successfully trade on the equity—use bondholders’ funds to earn additional profits.Finally, since the second alternative uses more debt, as reflected in the assets-to-equity ratio in c, the second alternative is probably preferred. The shareholders would take on additional risk with the second alternative, but the expected returns are greater as evidenced from computations in b.Exercise 8-2 (40 minutes)a. NOPAT = Net income = $10,000,000 x 10% = $1,000,000b. First alternative:NOPAT = $1,000,000 + $6,000,000*10% = $1,600,000Net income = $1,600,000 – ($2,000,000 ⨯ 5% x [1-.40]) = $1,540,000Second alternative:NOPAT = $1,000,000 + $6,000,000*10% = $1,600,000Net income = $1,600,000 – ($6,000,000 ⨯ 6% x [1-.40]) = $1,384,000c. First alternative: ROCE = $1,540,000 / ($10,000,000 + $4,000,000) = 11%Second alternative: ROCE = $1,384,000 / ($10,000,000 + $0) = 13.84%d. ROCE is higher under the second alternative due to successful use ofleverage—that is, successfully trading on the equity. [Note: Asset-to-Equity is1.14=$16 mil./$14 mil. (1.60=$16 mil./$10 mil.) under the first (second)alternative.] The company should pursue the second alternative in the interest of shareholders (assuming projected returns are consistent with current performance levels).a. RNOA = 2 x 5% = 10%b. ROCE = 10% + 1.786 x 4.4% = 17.86%c. RNOA 10.00%Leverage advantage 7.86%Return on equity 17.86%Exercise 8-4 (30 minutes)a. Computation and Interpretation of ROCE:Year 5 Year 9Pre-tax profit margin .......................................................... 0.112 0.109 Asset turnover .................................................................... 0.46 0.44 Assets-to-equity ................................................................. 3.25 3.40 After-tax income retention * .............................................. 0.570 0.556 ROCE (product of above) .................................................. 9.54% 9.07% * 1-Tax rate.ROCE declines from Year 5 to Year 9 because: (1) pre-tax margin decreases by approximately 3%, (2) asset turnover declines by roughly 4.3%, and (3) the tax rate increases by about 3.8%. The combination of these factors drives the decline in ROCE—this is despite the slight improvement in the assets-to-equity ratio.b. The main reason EPS increases is that shareholders had a large amount ofassets and equity working for them. Namely, the company grew while return on assets and return on equity remained fairly stable. In addition, the amount of preferred stock declined, as did the amount of preferred dividends. With this decline in the cost of carrying preferred stock, earnings available to common stock increased.(CFA Adapted)a. RNOA = 3 x 7% = 21%b. ROCE = RNOA + LEV x Spread = 21% + (1.667 x 8.4%) = 35%c. Net leverage advantage to common equityReturn on net operating assets .................................. 21%Leverage advantage .................................................... 14%Return on common equity (rounding difference) ..... 35%Exercise 8-6 (30 minutes)a. At the present level of debt, ROCE = $157,500 / $1,125,000 = 14%.In the absence of leverage, the noncurrent liabilities would be substituted with equity. Accordingly, there would be no interest expense with all-equityROCE without leverage = $184,500 / $1,800,000 = 10.25%.14% with leverage but only 10.25% without leverage.b. NOPAT = $157,500 + [$675,000 x 8% x (1-.50)] = $184,500RNOA = $184,500 / ($2,000,000-$200,000) = 10.25%c. The company is utilizing borrowed funds in its capital structure. Since theROCE is greater than RNOA, the use of financial leverage is beneficial to stockholders. Specifically, the after cost of debt is 4% and the financial leverage (NFO/Equity) is $675,000 / $1,125,000 = 60%. Therefore,ROCE = RNOA + LEV x Spread = 10.25% + 0.60 x (10.25% - 4%) = 14%, as before. The favorable effect of financial leverage is given by the term [0.60 x (10.25% - 4%)] = 3.75%.1. c2. a3. cExercise 8-8 (20 minutes)(Assessments of profit margin and asset turnover are relative to industry norms.)a.

Higher asset turnover and similar/lower profit margin.e. Higher asset turnover and lower/similar profit margin.f. Higher asset turnover and similar/higher profit margin.g. Higher asset turnover and lower profit margin.Exercise 8-9 (20 minutes)The memorandum to Reliable Auto Sales President would include the following points:•Both Reliable and Legend Auto Sales are perpetually investing $100,000 in automobile inventory.•Legend Auto Sales is able to generate more profit than Reliable because it is turning over its inventory (10 cars) more often. Specifically, Legend is turning its inventory over 10 times per year while Reliable is turning its inventory over only 5 times per year. Hence, given the same investment in automobile inventory, Legend is twice as profitable as Reliable.•Encourage Reliable to sacrifice some return on each sale to increase the inventory turnover. By slightly reducing price, relative to that charged by Legend, Reliable predictably will find that overall profitability increases. This is because while profit per sale declines, the number of units sold and, therefore, inventory turnover will increase. These factors predictably yield increased return on assets.Computation of Asset (PP&E) Turnover [computed as Sales / PP&E (net)]: Northern: $12,000 / $20,000 = 0.60Southern: $6,000 / $20,000 = 0.30This implies that Northern generates $0.60 in sales per year for each $1 investment in PP&E. In contrast, Southern generates $0.30 in sales per year for each $1 investment in PP&E. This shows that Northern is able to generate twice the return for each $1 invested in PP&E. Assuming equal profit margins, Northern will report a higher return on assets because of the volume of sales that the company is able to generate with its investment in PP&E (at least in the short run).Exercise 8-11 (15 minutes)Low volume operations mean that fixed costs, which in the case of automakers are substantial, must be absorbed by a low number of units produced. Since the lower of cost or market rule implies that inventory cannot be priced higher than expected sales price less costs of disposal plus a normal profit margin, much of that excess cost must be charged to the period incurred. In this case, that means the fourth quarter financial statements absorb much of this cost. This is probably the most likely accounting-based reason for the fourth quarter losses described in the news release.Problem 8-1 (30 minutes)a. 1. Quaker Oats does not reveal its computation of this return. Accordingly, wemake some simple computations and assumptions: (i) For simplicity, focus on one share, (ii) The dividend is $1.56 for Year 11, (iii) The average stock price is $55 and the price increase for Year 11 is $14—based on the beginning price of $48 and the ending price of $62. Using this information, we compute return to a share of stock as follows:= [Dividend per share + Price increase per share] / Average price per share = [$1.56 + $14] / $55= 28.3%However, if we use the beginning price of $48 per share, we get closer to the company's 34% return:= [$1.56 + $14] / $48= 32.4%2. The return on common equity is based on the relation between net incomeand the book value of the equity capital. In contrast, Quaker Oats’ “return t o shareholders” uses dividends plus market value change in relation to the market price per share (cost of investment to shareholders.)b. The company must have derived the 3.6% from price, market, and otherfactors that are not disclosed. Conceptually, this 3.6% should reflect the added risk of an investment in Quaker Oats’ stock vis-à-vis a risk-free security such as a U.S. Treasury bond.c. Quaker does not reveal its computations. It may disclose a variety of interestrates on long-term debt that it carries in the notes to financial statements.Based on data available to it, but not to the financial statement reader, it probably computed a weighted-average interest rate from which it deducted the tax benefit in arriving at the 6.4% cost of debt.a. Computation of Return on Invested Capital Measures:As a first step, we construct the company’s income statement.Sales (500,000 units @ $10). ................................................ $5,000,000 Fixed costs ....................................................................... 1,500,000 Variable costs (500,000 units @ $4). ............................. 2,000,000 Labor costs (20 employees x $35,000). ......................... 700,000 Income before taxes .......................................................... 800,000 Taxes (50% rate) ................................................................. 400,000 Net income .......................................................................... $ 400,000(1) RNOA = [$400,000 + ($2,000,000 x 7.5%)(1-0.50)] / ($8,000,000-$2,00,000)= $475,000 / $6,000,000 = 7.92%(2) ROCE = [$400,000 - ($1,000,000 x 6%)] / $3,000,000 = 11.33%Fixed costs ($1,500,000 x 1.06) ......................................................... 1,590,000 Variable costs ($550,000 units @ $4) .............................................. 2,200,000 Income before labor costs and taxes ............................................. $1,710,000 To obtain a 10% return on long-term debt and equity capital, Zear will need a numerator of $600,000 given an invested capital base of $6,000,000. The required operating income to yield this $600,000 amount is computed as: Net income + Interest expense x (1 - 0.50) = $600,000Net income + ($2,000,000 x 7.5%) x (1-0.50) = $600,000Net income = $525,000Assuming taxes at a 50% rate, Zear needs pre-tax income of $1,050,000, computed as:Income before labor and taxes ............ $1,710,000Labor costs ........................................... ?Pre-tax income ...................................... $1,050,000This implies:Labor costs = $660,000 orAverage wage per worker = $660,000 / 22 employees = $30,000 per employee Since the current salary level is $35,000, Zear cannot achieve its target return level and give a salary raise to its employees.(CFA Adapted)a.

The company is effectively using leverage, however, as indicated by the positive spread, but the leverage does not contribute significantly to Zeta’s return on equity and may not be worth the added risk.a.

Texas Talcom’s ROCE has increased form years 5 to 9. The source is thisincrease, however, has been an increase in RNOA as the leverage effect is zero in Year 9 since its long-term debt has been retired. Given the RNOA increase, additional leverage might be explored as a way to increase shareholder returns.Selling price per unit ...................... $6.00 $5.00 $50.00 $50.00 Unit cost ........................................... $5.00 $4.00 $32.50 $30.00Analysis of Variation in Product A SalesIncreased quantity at Yr 6 prices (3,000 x $5) ........................ $ 15,000 Price increase at Yr 6 quantity (7,000 x $1) ........................... 7,000 Quantity increase x price increase (3,000 x $1) .................... 3,000 Analysis of Variation in Product A Cost of SalesIncreased quantity at Yr 6 cost (3,000 x $4) ...........................

Performance in Year 9 is poor when compared with Year 8. One bright spot isthe percentage of Cost of Goods Sold to Sales, which decreased in Year 9.However, Operating Expenses climbed sharply. This sharp climb in operating expenses is unexpected since there is usually a larger fixed cost component comprising these costs compared with that for Cost of Goods Sold.Management should further check operating expenses. If operating expenses had remained at the Year 8 level of 10.2%, income would have been up favorably for Year 9. Operating expenses may have included a future-directed component such as advertising or training costs. Also, management would want to follow up on the change in gross margin. The sharp improvement in gross margin may have been due to factors such as the liquidation LIFO inventory layers or, alternatively, to something more fundamental with the activities of the firm.。

Sporulation
• During infection, phage SPO1 changes specificity of host RNA polymerase
• More radical shifts in gene expression require more fundamental changes in the transcription machinery
• Three major mechanisms:
-factor switching – RNA polymerase switching – antitermination
