Iowa Curves

A graphical representation showing the proportion of an asset population that remains in service over time, plotted from 100% at inception to 0% at the end of the longest-surviving unit's life. Survival curves are used in intangible asset valuation to model the expected decay pattern of customer relationships, subscriber bases, and other wasting intangibles.

The rate at which a company's existing customers cease doing business with it over a given period, typically expressed as an annual percentage. Customer attrition rate is a critical input to the valuation of customer relationship intangible assets under both the multi-period excess earnings method and the distributor method.

The average remaining period over which a group of intangible assets is expected to contribute to cash flows, weighted by their individual fair values. WARUL is used in purchase price allocation to determine amortisation periods for acquired intangible assets and is required disclosure under several accounting standards.

An income approach valuation technique that values a primary intangible asset by isolating the cash flows attributable to it after deducting fair returns on all other contributory assets. MPEEM is the most commonly used method for valuing customer relationships in purchase price allocations under IFRS 3 and ASC 805.

An actuarial valuation methodology used to value life insurance companies, representing the present value of future profits from the existing book of insurance policies (the value of in-force business) plus the adjusted net asset value of the company. Embedded value is the standard valuation framework for life insurers and is analogous to the net asset value plus intangible asset value approach used in other industries.

A variant of the multi-period excess earnings method used to value customer relationship intangible assets, which analyses the business from the perspective of a hypothetical distributor that owns only the customer relationships and licenses all other assets from the operating entity. The distributor method simplifies contributory asset charge estimation by modelling a lean distribution business rather than the full operating entity.

A set of measurement guidelines and statistical standards developed by the Organisation for Economic Co-operation and Development for comparing productivity across countries and sectors. The OECD framework addresses the treatment of intangible investment, quality adjustment, and multi-factor productivity, providing the foundation for international productivity benchmarking.

A forecasting and valuation technique based on the logistic growth function, which models the adoption or diffusion of technology, products, or innovations as a characteristic S-shaped curve with slow initial growth, rapid acceleration, and eventual saturation. S-curve analysis is used in intangible asset valuation to project revenue trajectories for technology assets, assess the remaining useful life of patents, and evaluate where a product sits in its lifecycle.
