The Financial Soundness
of US Firms 1926-2013
Andrew Atkeson, Andrea Eisfeldt, and Pierre-Olivier Weill
Bank of Portugal, June 2015
Finance and the Real Economy
• 2008 Financial Crisis and Great Recession
New interest in old questions:
What is the role of financial frictions in business cycles?
Are recessions with financial crises different?
How can we measure the financial soundness of firms?
• Today: a contribution to measurement
Finance and the Real Economy
• We provide measurement, going ahead of the following theory:
Heterogeneous firms choose output, employment, investment
Financial frictions impact activity of financially unsound firms
⇒ Aggregate State = Cross-Section of Financial Soundness
• Measure financial soundness as Distance to Insolvency (DI)
Captures leverage adjusted for asset volatility
≈ Inverse of equity volatility
• DI, Financial Frictions, and Business Cycles:
Statistical view: low distance ⇒ likelihood of insolvency is high
Economic view: low distance ⇒ financial frictions are high
e.g. bankruptcy costs, debt overhang, risk shifting
What we find
• Three Big Recessions, Three Broad and Deep Insolvency Crises
1929-1933, 1937, 2008
Deep: Median firm in extreme distress
Broad: 95% of firms junk
Very different from other recessions
• Volatility vs. Leverage:
2008 contraction driven by an increase in asset volatility
Leverage did not play as big a role as previously emphasized
Majority contribution from idiosyncratic risk
What is New
Our contribution to measurement is:
• Extend back to 1926
• Utilize a broad cross section
• Decompose changes in finanancial soundness distribution into:
1 Component due to leverage
2 Component due overall volatility
a Contribution of aggregate volatility
b Contribution of idiosyncratic volatility
⇒ Stylized Facts to confront our quantitative models with.
Theory and Measurement
Distance to Insolvency
• Firm Balance Sheet: Assets and Liabilities
VAt : Expected DPV of cash flows from the firm’s assets
VBt : DPV of the promised cash flows on liabilities
• Insolvency = Assets worth less than Liabilities, VAt < VBt
• Distance to Insolvency:
VAt −VBt
VAt
1
σAt
The percentage drop in asset value that renders the firm insolvent,
measured in units of the firm’s asset standard deviation

Measurement
• Propose an approximate measure
Distance to Insolvency (DIt ) ≈
1
σEt
• Motivate with theory, calibrate and validate with data
• With unlimited liability, the approximation is exact:
Equity is a leveraged claim on assets: VEt = VAt − VBt
Instantaneous volatility of equity: σEt =
VAt
VEt
× σAt
Plug the first equation into the second one and take inverses:

=
σEt
VAt − VBt

• VE ≥ max{0, VA − VB }

• δV
δVA ∈ [0, 1) and δVA2 > 0
• VE (VA∗ ) = 0 where VA∗ is the default boundary, then

creditors force insolvent firm into bankruptcy

insolvent firm into bankruptcy as soon as it is insolvent.VA - VB

• Why is our approximation useful?
Robust to model misspecification
Does not require any accounting data
Captures off-balance sheet leverage
Long time series available

Calibrating and Validating DI
Calibrating and Validating DI
• Calibration: What does level of DI mean in terms of credit rating?
• Validation: DI vs. Other measures of financial soundness.
Bond spreads
CDS Swap rates
Default Rates
• Is the relationship btw DI and financial soundness stable?
Calibrating DI
Using credit ratings :
• Above 4: Good and safe
• At 3: Cutoff between Investment Grade and Speculative Grade
• Below 2: Vulnerable
• Below 1: Highly vulnerable to bankruptcy or default

Distribution of Financial Soundness
Measurement: 1926-2012
• Measure DIt as 1/σEt monthly for each firm
• Calculate σEt = standard deviation of daily returns in month
Every NYSE, AMEX, and NASDAQ firm in CRSP
Every month, 1926 to 2012
• Construct cross-section distribution of DIt every month
Start with several hundred firms per month
End with several thousand

Asset Volatility
• An advantage of our structural approach!
• Use unlimited liability benchmark:

Conclusions
• Insolvency Crises in three big recessions
Broad: 95% of firms junk
Deep: median firm well below junk cutoff
Not so for other recessions
• Asset volatility key driver, especially idiosyncratic volatility
⇒ Need structural models which match stylized facts above, and,
can asses how changes in the financial soundness of firms:
Can drive business cycles, and match firm behavior
in x-section of financial soundness in normal times
