An equity management and planning tool for cooperatives

Abstract

Purpose

The purpose of this paper is to describe an equity management and planning tool used by rural electric cooperatives (RECs) and based on the times-interest-earned ratio (TIER). The objectives of the paper are to construct a mathematical model that provides a rigorous foundation for the TIER approach, modify the approach so the rate of return on equity is a function of the cooperative’s equity position, demonstrate how elements of the model can be used by RECs in setting electric rates that will enable them to accelerate the retirement of member equity, and derive a generalized form of the “modified Goodwin formula” that can be used by both RECs and agricultural cooperatives.

Design/methodology/approach

Mathematical and graphical expressions of the TIER approach are developed. Simulations are used to demonstrate how RECs can set electric rates according to a target revolving period. The modified Goodwin formula is generalized to include the payment of cash patronage refunds through use of a growth model of an agricultural cooperative developed in Royer (1993).

Findings

This paper demonstrates how TIER analysis and the modified Goodwin formula can be used by cooperatives to aid their decisions regarding debt and equity financing and their choices regarding cash patronage refunds, equity retirement, and growth. The paper demonstrates that cooperatives that fail to recognize the functional relationship between the rate of return on equity and the equity position may substantially underestimate the equity position necessary to meet interest coverage requirements and overestimate their ability to grow and retire equity. It also shows that RECs may be able to make substantial improvements in equity revolvement with only modest increases in electric rates.

Research limitations/implications

The model developed in this paper has been simplified to focus on fundamental financial relationships. To apply this model, cooperatives may need to modify it to accommodate the complexities of their business operations.

Practical implications

TIER analysis can provide a useful equity management and planning tool for both RECs and agricultural cooperatives. It also can be used by lending institutions to assess the financial health of individual cooperative organizations.

Originality/value

Constructing a mathematical model that provides a foundation for TIER analysis, modifying the approach so that the rate of return on equity is a function of the equity position, demonstrating how RECs can use the model to set electric rates according to a target revolving period, and generalizing the modified Goodwin formula so it can be used by agricultural cooperatives are all original contributions.
