The OEB determines the values for the Return on Equity (ROE) and the deemed Long-Term (LT) and Short-Term (ST) debt rates for use in cost of service and custom incentive rate-setting (custom IR) applications. The ROE and the LT and ST debt rates are collectively referred to as the cost of capital parameters.
