We propose a genuinely internal approach to project valuation and decision based on the average Return On Investment (ROI), obtained as the ratio of total operating profit (NOPAT) to total invested capital or, equivalently, as the ratio of net cash flow to total invested capital. The approach...

The average internal rate of return (AIRR), introduced by Magni (2010), fixes many deficiencies associated with the traditional internal rate of return (IRR), including apparent inconsistency with net present value (NPV). The AIRR approach breaks down project NPV into scale (the capital...

We show that the standard notion of residual income (RI) does not fulfill additive coherence. This gives rise to ambiguities and inconsistencies. The pitfall resides in the capital charge, which blends a non-market value with a market rate. We solve the problem by using a capital charge based on...

Evaluating an industrial opportunity often means to engage in financial modelling which results in estimation of a large amount of economic and accounting data, which are then gathered in an economically rational framework: the pro forma financial statements. While the standard net present value...

Literature and textbooks on capital budgeting endorse net present value (NPV) and generally treat accounting rates of return as not being reliable tools. This paper shows that accounting numbers can be reconciled with NPV and fruitfully employed in real-life applications. Focusing on project...

This paper generalizes Makeham's formula, allowing for varying interest rates and for a non-flat structure of valuation rates. An average interest rate (AIR) is introduced, as well as an average valuation rate (AVR), which exist and are unique for any asset. They can be computed either as...

In Jiang's (2017, JAI, 9 (4): 77–91), the author proposes an interesting metric, which is a special case of Average Internal Rate of Return (AIRR), introduced in Magni (2010). In the paper, the author also deals with Economic AIRR (EAIRR) (Magni 2013) and ICM-based AROI (Magni 2011, Altshuler...

This paper expands Teichroew, Robichek and Montalbano's (TRM) (1965a, b) rate-of-return model into a complete and general model of economic profitability for investment decision-making. Specifically, TRM's assumptions are relaxed and a project rate of return is derived, expressing the project's...

This paper shows that the Internal-Rate-of-Return (IRR) approach is unreliable, and that the recently introduced Average-Internal-Rate-of-Return (AIRR) model constitutes the basis for an alternative theoretical paradigm of rate of return. To this end, we divide the paper into two parts: a pars...

This paper introduces new money-weighted metrics for investment performance analysis, based on arithmetic means of holding period rates weighted by the investment's market values. This approach generates rates of return which measure a fund's or portfolio's performance and a fund manager's...
