Exposure-Based Cash-Flow-At-Risk under Macroeconomic Uncertainty

In this paper we derive an exposure-based measure of Cash-Flow-at-Risk (CFaR). Existing approaches to calculating CFaR either only focus on cash flow conditional on market changes or neglect market-risk exposures entirely. We argue here that an essential first step in a risk-management program is to quantify cash-flow exposure to macroeconomic and market risk. This is the information relevant for corporate hedging. However, it is the total level of cash flow in relation to the firm's capital needs that is the information relevant for decision-making. The firm's overall CFaR is then calculated based on an assessment of corporate risk exposure
