ON DERIVING THE INTERNAL RATE OF RETURN FROM THE ACCOUNTANT'S RATE OF RETURN

L.A. Gordon (J.B.F.A. Vol. 1 No, 3) claims to have derived a method for approximating the IRR using the ARR. This paper demonstrates that the key relationship in Gordon's paper is only valid if the IRR is already known and used to calculate economic depreciation. It is suggested that Gordon has merely derived a means for refining ARR, but not for deriving IRR.
Dans son article paru dam Vol. 1 No 3 de ce journal, L.A. Gordon prétend avoir introduit une méthode qui permet d'évaluer "Internal Rate of Return" au moyen de "Accountant's Rate of Return". Ce papier démontre que le rapport-clé dont Gordon nous fait part n'est vérifiable que si "Internal Rate of Return" est préablement connu et sert a calculer l'amortissement économique. On insinue ainsi que Gordon a simplement présenté un moyen de perfectionner "Accountant's Rate of Return" mais n'en a pas démontré pour autant l'évaluation de "Internal Rate of Return".
L.A. Gordon (J.B.F.A. Band 1, Nr. 3) behauptet, er habe eine Annäherungsmethode abgeleitet, womit der interne Zinsfuss von dem RO1 Kriterium berechnet werden kann. Dieser Beitrag zeright, dass das Schlüsselverhältnis in Gordons Abhandlung nur dann gültig ist wenn der interne Zinsfull schon bekannt ist und als kalkulatorischer Zinssatz für ökonomische Abschreibungsbetrage verwendet wird. Es wird behauptet, dass Gordon keine Methode für die Ableitung des internen Zinsfusses entwickelt hat, sondern nur eine für die Verbesserung des R01 Kriteriums.     

THE RATE OF RETURN FROM INTERIM FINANCIAL REPORTS AND THE ALLOCATION PROBLEM IN FINANCIAL ACCOUNTING

Estimation theory in accounting explains how accountants allocate noncash expenditures to estimate such concepts as the firm's long run rate of return. If the accountant's goal in estimation is some high degree of precision, the usefulness of financial reports can be evaluated in light of that goal. In this study, the property of unbiasedness is identified with respect to the purposes of interim financial reports. Furthermore, the magnitude of the bias in estimates from financial reports is measured.     

PROJECT HOLDING-PERIOD RATE OF RETURN AND THE MIRR

In this paper we examine the relationship between the Modified Internal Rate of Return (MIRR) and a project's expected holding-period rate of return assuming that cash flows are reinvested at the cost of capital. When cash flows are uncertain, the MIRR overstates the expected holding-period rate of return. The relationship between the MIRR and a project's expected holding-period rate of return is shown to be a simple function of conventional project statistics like the coefficient of variation of the present value of random cash flows, the profitability index, the cost of capital, and the project's life.     

ESTIMATING THE INTERNAL RATE OF RETURN FROM PUBLISHED FINANCIAL STATEMENTS

This paper presents a new approach to estimating the longrun internal rate of return (IRR) for the firm from the accountant's rate of profit based on published financial statements. The model developed for estimating the IRR includes both capital and net working asset investments. Modelling and estimating the growth of the firm is an integral part of the approach. Furthermore, estimating the parameters describing the long-run financing behavior of the firm is presented based on discounted average funds flow statements. Finally, the approach is applied on the financial data of a large Finnish business enterprise.
