【正文】 運營中和借貸的融資業(yè)務中產生的利潤。本文的實證結果表明，能夠區(qū)分運營中的杠桿作用和融資中的杠桿作用的財務報表分析也能夠區(qū)分公司當前和未來的盈利情況。我們的研究結果是用于愿意分析預期公司的收益和賬面收益率。第一部分概述并指出了了能夠判別兩種杠桿作用類型，連接杠桿作用和盈利的財務報表分析第二節(jié)將杠桿作用，股票價值和價格與賬面比率聯(lián)系在一起。普通股本 ?。?）杠桿影響到這個盈利等式的分子和分母。 區(qū)分運營和融資過程中的盈利普通股權=經營資產＋金融負債－經營負債－金融負債 （2）側重于普通股（以便優(yōu)先股被視為融資債務），資產負債表方程可重申如下：經營性資產的區(qū)別（如貿易應收款，庫存和物業(yè)，廠房及設備）和金融資產（存款及可出售證券吸收多余現(xiàn)金）在其他方面。這種區(qū)別并不像當前與長遠負債那么簡單。因此，一個公司可能在投資清單上的投資，但是投資清單上的投資者可以一定程度上給予信貸，投資清單上的投資就會減少。事實上一個公司的可能是一個凈債權者（更多的金融資產與金融負債比），而不是凈債務者。如果利息收入大于利息支出，融資活動產生凈財政收入，而不是凈財務支出。凈資產債務。值得注意的是，凈資產收益率不同于較常見的資產收益率（資產回報率），通常被定義為總資產在稅后利息前的收入。 財務杠桿作用和其對股東盈利的影響從式（3）到式（6）可以推算出來運用資本報酬率是凈資產收益率和凈借貸率平均值。普通股權 ?。?）財務杠桿作用排除了運營負債，但是包括（作為凈反對融資的債務）金融資產。財務杠桿凌駕于運用資本報酬率和凈資產收益率之上，其中杠桿效應由財務杠桿決定，由凈資產收益率和借貸率調節(jié)。在投資中，運營負債的應用頻率就是運營杠桿作用。供應商對信貸的收費很難量化，但是市場借貸率是可以觀察到的。為了分析運營債務杠桿對運營盈利的影響，定義如下：經營資產收益率=（經營收入＋經營負債的市場利率）247。類似于資本收益率的平衡方程（8），凈經營資產回報率用可表示為：凈資產收益率=經營資產收益率＋[經營負債杠桿（經營資產收益率－市場借貸率）] （12）借貸率是稅后短期利率。 杠桿作用和對股東收益的影響經營負債和凈財務負債結合進總杠桿的辦法：總杠桿=（凈金融負債＋經營負債）247。區(qū)分盈利來源的唯一要素是在財務分析上，運營和融資組成上有一個明確的區(qū)分。溢價取決于預算剩余收入，剩余收入部分取決于與面值有關的相關收入，也就是預算的資本收益率。在這種情況下，賬面價值的不同組成可能導致不同的收益率。應計債務可能基于合同條款，但通常包括估計我們考慮了實際效果的影響的收縮和會計估計。但是估價問題涉及到事后效果。在Mamp。在任何情況下，經營負債的隱含成本，像金融負債的利息，是稅務抵減額，杠桿組成不涉及稅務。事實上本文已經闡述了交易成本使用經營債務而非金融債務（Ferris, 1981），財務上供應商和客戶使用不同的方法（Schwartz,1974），信息有事和比較成本控制。其他研究的參考作用歸咎于經營負債。更多的來自于進一步放寬資本的完美無摩擦市場假設原來的M機電融資無關化。在行動上，企業(yè)可以施加壟斷權力，從供應商和員工提取價值。應計負債可根據(jù)合同條款，但通常涉及估計。而且還涉及估計，以及收入分配時期。會計估計對經營責任杠桿的影響很明確：高等教育賬面值為經營負債導致更高的杠桿一定水平的經營性資產。通過利用方程（13），即杠桿效應流經到股東盈利能力和回報?，F(xiàn)在的收入低一點，否則成本升高。更重要的是，高的運營債務和低的運營資產意味著低的值比率的公平性。（3）書面價值只是1千億美元。一種值得討論的測量觀點是運營債務的借用消費。向我們展示的，這種負相關即使存在，也可以證明其正相關。尤其是，運營資本可能縮水，因此價格不同。對于運營債務杠桿，杠桿平衡包括真實的契約效應和賬目效應。運營債務杠桿作用和變化可以作為當今盈利和以后盈利的風向標。 operating liability leverage。 pension liabilities, for example, are usually longterm, and shortterm borrowing is a current liability.Rearranging terms in equation (2),Common equity = (operating assets－operating liabilities)－(financial liabilities－financial assets)Or,Common equity = net operating assets－net financing debt (3)This equation regroups assets and liabilities into operating and ?nancing activities. Net operating assets are operating assets less operating liabilities. So a ?rm might invest in inventories, but to the extent to which the suppliers of those inventories grant credit, the net investment in inventories is reduced. Firms pay wages, but to the extent to which the payment of wages is deferred in pension liabilities, the net investment required to run the business is reduced. Net ?nancing debt is ?nancing debt (including preferred stock) minus ?nancial assets. So, a ?rm may issue bonds to raise cash for operations but may also buy bonds with excess cash from operations. Its net indebtedness is its net position in bonds. Indeed a ?rm may be a net creditor (with more ?nancial assets than ?nancial liabilities) rather than a net debtor.The ine statement can be reformulated to distinguish ine that es from operating and ?nancing activities:Comprehensive net ine = operating ine－ net financing expense (4)Operating ine is produced in operations and net ?nancial expense is incurred in the ?nancing of operations. Interest ine on ?nancial assets is netted against interest expense on ?nancial liabilities (including preferred dividends) in net ?nancial expense. If interest ine is greater than interest expense, ?nancing activities produce net ?nancial ine rather than net ?nancial expense. Both operating ine and net ?nancial expense (or ine) are after Equations (3) and (4) produce clean measures of aftertax operating pro?tability and the borrowing rate:Return on net operating assets (RNOA) = operating ine 247。mon equity RNOA]－[net financing debt247。 there may be a numerator effect on operating ine. Suppliers provide what nominally may be interestfree credit, but presumably charge for that credit with higher prices for the goods and services supplied. This is the reason why operating liabilities are inextricably a part of operations rather than the ?nancing of operations. The amount that suppliers actually charge for this credit is dif?cult to identify. But the market borrowing rate is observable. The amount that suppliers would implicitly charge in prices for the credit at this borrowing rate can be estimated as a benchmark:Market interest on operating liabilities= operating liabilitiesmarket borrowing ratewhere the market borrowing rate, given that most credit is short term, can be approximated by the aftertax shortterm borrowing rate. This implicit cost is benchmark, for it is the cost that makes suppliers indifferent in supplying cred suppliers are fully pensated if they charge implicit interest at the cost borrowing to supply the credit. Or, alternatively, the ?rm buying the goods or services is indifferent between trade credit and ?nancing purchases at the borrowin rate.To analyze the effect of operating liability leverage on operating pro?tability, we de?ne:Return on operating assets (ROOA) =(operating ine＋market interest on operating liabilities)247。M) (1958) ?nancing irrelevance proposition: With perfect capital markets and no taxes or information asymmetry, debt ?nancing has no effect on value. In terms of the residual ine valuation model, an increase in ?nancial leverage due to a substitution of debt for equity may increase expected ROCE according to expression (8), but that increase is offset in the valuation (14) by the reduction in the book value of equity that earns the excess pro?tability and the increase in the required equity return, leaving total value (., the value of equity and debt) unaffected. The required equity return increases because of increased ?nancing risk: Leverage may be expected to be favorable but, the higher the leverage, the greater the loss to shareholders should the leverage turn unfavorable ex post, with RNOA less than the borrowing rate.In the face of the
