What Is Return on Risk-Adjusted Capital – RORAC?

The return on risk-adjusted capital (RORAC) is a rate of return measure commonly used in financial analysis, where various projects, endeavors, and investments are evaluated based on capital at risk. Projects with different risk profiles are easier to compare with each other once their individual RORAC values have been calculated. The RORAC is similar to return on equity (ROE), except the denominator is adjusted to account for the risk of a project.

The Formula for RORAC Is

﻿\begin{aligned} &\text{Return on Risk Adjusted Capital}=\frac{\text{Net Income}}{\text{Risk Weighted Assets}}\\ &\textbf{Where:}\\ &\text{Risk risk-weighted assets are also known as allocated risk capital, economic capital or value at risk.}\\ \end{aligned}﻿

How to Calculate Return on Risk-Adjusted Capital – RORAC

Return on Risk-Adjusted Capital is calculated by dividing a company’s net income by the risk-weighted assets.

What Does Return on Risk-Adjusted Capital (RORAC) Tell You?

Return on risk-adjusted capital takes into account the capital at risk, whether it be related to a project or company division. Allocated risk capital is the firm's capital, adjusted for a maximum potential loss based on estimated future earnings distributions or the volatility of earnings.

Companies use RORAC to place greater emphasis on firm-wide risk management. For example, different corporate divisions with unique managers can use RORAC to quantify and maintain acceptable risk-exposure levels. This calculation is similar to risk-adjusted return on capital (RAROC). With RORAC, however, the capital is adjusted for risk, not the rate of return. RORAC is used when the risk varies depending on the capital asset being analyzed.

Key Takeaways

• RORAC is commonly used in financial analysis, where various projects or investments are evaluated based on capital at risk.
• Allows for an apples-to-apples comparison of projects with different risk profiles.
• Similar to risk-adjusted return on capital, but RAROC adjusts the return for risk, not the capital.

Example of How to Use RORAC

Assume a firm is evaluating two projects it has engaged in over the previous year and needs to decide which one to eliminate. Project A had total revenues of $100,000 and total expenses of$50,000. The total risk-weighted assets involved in the project is $400,000. Project B had total revenues of$200,000 and total expenses of $100,000. The total risk-weighted assets involved in Project B is$900,000. The RORAC of the two projects is calculated as:

﻿\begin{aligned} &\textbf{Project A RORAC}=\left(\100,000-\50,000\right)\div\400,000=12.5\%\\ &\textbf{Project B RORAC}=\left(\200,000-\100,000\right)\div\900,000=11.1\%\\ \end{aligned}﻿

Even though Project B had twice as much revenue as Project A, once the risk-weighted capital of each project is taken into account, it is clear that Project A has a better RORAC.

The Difference Between RORAC and RAROC

RORAC is similar to, and easily confused with, two other statistics. Risk-adjusted return on capital (RAROC) is usually defined as the ratio of risk-adjusted return to economic capital. In this calculation, instead of adjusting the risk of the capital itself, it is the risk of the return that is quantified and measured. Often, the expected return of a project is divided by value at risk to arrive at RAROC.

Another statistic similar to RORAC is the risk-adjusted return on risk-adjusted capital (RARORAC). This statistic is calculated by taking the risk-adjusted return and dividing it by economic capital, adjusting for diversification benefits. It uses guidelines defined by the international risk standards covered in Basel III.

Limitations of Using Return on Risk-Adjusted Capital – RORAC

Calculating the risk-adjusted capital can be cumbersome as it requires understanding the value at risk calculation.
