Resolving the Exposure Puzzle:The Many Facets of Exchange Rate ExposureFDICOctober 27, 2006 Söhnke M. Bartram Lancaster University Gregory W. Brown University of North Carolina Bernadette A. Minton Ohio State University
Motivation • FX risk is a major financial risk to nonfinancial firms • “FX Exposure Puzzle” • Theoretical models predict exposure • Bodnar, Dumas and Marston 2002; Marston 2001; Adler and Dumas 1984; Shapiro 1975 • Empirical studies find weak evidence • Allayannis and Ihrig 2001; Dominguez and Tesar 2001a,b; Griffin and Stulz 2001; Williamson 2001
How to Resolve the Puzzle? • General idea/hypothesis of this paper • Firms do have potentially large FX risk • Pricing and financial policies reduce exposures • Analysis • Use structural models to analyze different facets of FX exposure and hedging • Gross (or pre-hedging) exposure • Net (or post-hedging) exposure
What We Do • Motivating Example: Global Automotive Industry • Bodnar and Marston (2002) model • Detailed firm-level data • Enhanced Bodnar, Dumas and Marston (BDM, 2002) model • Firm selling and producing in local and foreign market • Exposure is a function of: • market share • product substitutability, • sales and cost in foreign currency • Use model to analyze a large sample of global manufacturing firms around the world
Contribution • Resolving the Exposure Puzzle • Model predicts that firms should have large gross FX exposures • Firms reduce these exposures via three channels: • Pass-through (10%-15%) • Operational hedging (10%-15%) • Financial hedging (45%-50%) • Residual FX exposures (as estimated in the prior literature) are economically and statistically small
Automotive Industry • Industry study to motivate main analysis • 16 auto manufacturers from 6 countries • Mature and competitive industry • Important FX risk (Williamson 2001) • Bodnar and Marston (2002) h1: percent foreign sales h2: percent foreign cost r : profit margin
BDM Model • FX exposure of exporter • Exposure depends on • Product market competition => pass-through r: degree of product substitutability l: market share of exporting firm in foreign market • Operational Hedging g: fraction of marginal cost due to foreign currency-based inputs
Enhanced BDM Model • Two extensions of BDM model • Both firms can have cost in local and foreign currency • Firm sells globally • Global firm is sales-weighted average of foreign and domestic operations (f is percent of foreign sales). • Model is more broadly applicable • Captures global firms in global markets • Allows for broader set of exposures and pass-through • BDM model is a special case of enhanced model
Enhanced BDM Model • Foreign Exchange Rate Exposure • Foreign Exchange Rate Pass-Through
Sample and Data • 1,161 manufacturing firms from 16 countries • Accounting data (USD) (Thomson) • Market data (LC) (Datastream) • Import penetration (UNIDO, SSIS) • Herfindahl indices to measure industry competition (complete Worldscope universe) • Collect data from annual reports for FX derivatives and foreign currency debt
Importance of Hedging Channels • Gross FX exposure = 0.674 • no market share, no foreign assets, no financial hedging • values at sample means, rf=rd =0.7 • Firms reduce FX exposure via 3 channels (1) Pass-through (10%-16%) - Market shares at sample average (2) Operational hedging (9%-16%) - Foreign assets at sample average (3) Financial hedging (46% - 50%) - FC Debt (45%) - FX Derivatives (1%) • Consistent with Guay and Kothari (2003), derivatives have limited impact on risk profile of the firm
Summary • Comprehensive analysis of FX exposure • Resolving the “Exposure Puzzle” • Firms have large gross FX exposures • Firms reduce these exposures via pass-through, operating and financial hedging • Residual FX exposures are economically and statistically small • FX risk management is effective, and companies can stop whining about FX risk
