2
What is a balance sheet?
  • Shows the financial position of an enterprise at
    a given point in time
  • Provides information about what an enterprise
    owns(assets), owes (liabilities) and its value to
    its inverstors (share holders equity)
  • Accounting equation
  • Assets Liabilities stockholders equity
  • Measured at a point in time

Balance Sheet
4
Balance Sheet terminology
  • Asset
  • Any item of economic value owned by a corporation
  • Liabilities
  • A financial claim, debt or potential loss that is
    owed by a corporation
  • Stockholders Equity
  • Value of the business a corporation generates
    that it owes to its shareholders after all its
    obligations have been met

5
Balance Sheet terminology Continued
  • Basic Accounts Equation
  • Asset Liabilities Shareholders equity
  • Owners Equity
  • Owners claim on the assets
  • Owners total investment

6
Prediction of Financial Distress
  • Process of estimating the probability of the
    bankruptcy of a corporation by using financial
    ratios and existing models.

7
Models used in the prediction of financial
distress
  • Z-Score Model
  • Vasicek-Kealhofer model
  • Black- Scholes Merton Probability
  • Compensator Model

8
The Z-score Model
  • First developed by Altman in 1968
  • Uses a specified set of financial ratios as
    variables in multidiscriminant statistical
    methodology (MDR)
  • Real world application of the Altman score
    successfully predicted 72 of bankruptcies 2
    years prior to their filing for Chapter 7

9
Multi Discriminant Analysis
  • Used to classify an observation into several
    groupings
  • The groupings are based on an observations
    individual characteristics
  • MDR is used while making predications in problems
    where the variable dependant variable appears in
    qualitative form. Eg. Bankrupt and non-bankrupt
  • Forms a linear equation using characteristics
    that can be used to distinguish between the
    dependant variable groups

10
Z-score model reprise
  • Uses five financial ratios
  • Ratios are objectively weighed and summed
  • Ratios can be obtained from corporations
    financial statements

11
Z-score constituent ratios
  • Working Capital/total assets (WC/TA)
  • Working Capital is the difference between the
    current assets and current liabilities as
    obtained from the balance sheet
  • Retained Earnings/total assets ( RE/TA)
  • Retained Earning is also know as the earned
    surplus
  • It represents the total amount of reinvested
    earnings and/or losses of a firm over its entire
    life-cyle
  • Can be obtained from balance sheet
  • Earnings before interest and taxes/Total assets
    (EBIT/TA)
  • Measure of a corporations earning power from
    ongoing operations
  • Also know as Operating profit
  • Watched closely by creditors as it represent the
    total amount of cash that a corporation can use
    to pay off its creditors
  • Can be obtained for the Income statement

12
Z-score constituent ratios Continued
  • Market Value of Equity/Book Value of total
    liabilities (MVE/TL)
  • The market value of equity is the total market
    value of all of the stock, both preferred and
    common
  • The book value of liabilities is the total value
    of liabilities both long term and current
  • The MVE/TL shows how much the firms assets can
    decline in value with increasing liabilities,
    before the liabilities exceed the assets
  • Sales/Total Assets (s/TA)
  • Also known as capital turnover ratio
  • Illustrates the sales generating ability of the
    corporations assets

13
Z score Results
  • Based on Z-scores averaged over time, Altman
    calculated that a Z-score lt2.675 could be
    classified as failed
  • More accurately, Zlt1.81 signals bankruptcy within
    1 year
  • Z gt 2.99 signals the firm is in good financial
    health

14
VK model
  • Uses EDF (expected default frequency) credit
    measures the probability that a company will
    default within a given timeframe
  • 3 main elements are used to determine the default
    probability
  • Market Value of assets
  • Asset Risk
  • Leverage Extent of the corporations
    contractual liabilities. It is the book value of
    liabilities relative to the market value of
    assets

Leverage
Market Value of Assets

Default Point (Liabilities Due)

  • Default risk increases as the market value of the
    assets approaches the book value of the
    liabilities.

16
Market net worth
  • Market net worth is market value of the companys
    assets minus the default point
  • Market net worth is considered in context of the
    business risk
  • Food and beverage industries can afford higher
    leverage( lower market net worth) than technology
    businesses because their asset values are more
    stable

17
Asset Volatility
  • It is the standard deviation of the annual
    percentage change in the asset value
  • It is related to the size and nature of the
    industry
  • It can be calculated from the value of the
    increase or decrease in percentage of asset value
    upon 1 standard deviation change in the asset
    value

Distance to Default
  • Compares the market net worth to the size of a 1
    standard deviation move in the asset value
  • Combines 3 key credit issues
  • Value of firms assets
  • Business and industry risk
  • leverage

20
Determining Default Probability
  • 3 steps to determine default probability
  • Estimate Asset value and volatility
  • Equity is a call option on asset value. Equity
    holders have the right but are not obligated to
    pay off the debt holders
  • Solve for implied asset value and volatility
  • Calculate Distance to default
  • Contractual obligations determine Default Point
  • Number of standard deviations from default
  • Calculate Default probabilty
  • Assign EDF using actual historical rates

21
Black-Sholes-Merton Probability
  • Volatility is crucial variable in bankruptcy
    prediction since it captures the likelihood that
    the values of firms assets will decline to such
    an extent that the firm will be unable to repay
    its debts
  • Equity can be viewed as a call option on the
    value of the firms assets. The strike price of
    the call option is equal to the face value of the
    firms liabilities and the option expires at time
    T when the debt matures.
  • The BSM equation
  • Where N(d1) and N(d2) are the standard cumulative
    normal of d1 and d2 and

22
  • VE is the current market value of equity VA is
    the current market value of assets X is the face
    value of debt maturing at time T r is the
    continuously-compounded risk-free rate d is the
    continuous dividend rate expressed in terms of VA
    and ?A is the std deviation of asset returns.
  • Under the BSM model . The probability of
    bankruptcy is simply the prob that the market
    value of assets , VA is less than the face value
    of the liabilities, X, at time T (i.e VA(T) lt X).
    The BSM model assumes that the natural log of
    future asset values is distributed normally as
    follows, where u is the continuously compounded
    expected return on assets

23
  • The probability that VA(T) lt X is as follows
  • This shows the prob of bankruptcy is a function
    of the distance btw the current value of the
    firms assets and the face value of the
    liabilities adjusted for the expected
    growth in asset values
  • relative to the asset volatility
  • We must estimate the market value of assets,
    asset volatility and the expected return on
    assets.
  • We estimate the values of VA and by
    simultaneously solving the call option equation
    and the optimal hedge eqn
  • We solve the two equations simultaneously for the
    two unknown variables VA and .The
    starting values are determined by setting VA
    equal to book value of liabilities plus market
    value of equity and
  • In the second step, we estimate the expected
    market return on assets, u, based on the actual
    return on assets during the previous year, based
    on the estimates of VA that were computed in the
    previous step.

24
  • Finally we use these values to calculate the
    BSM-Prob for each firm year.

25
Compensator Model
  • Based on the assumption of incomplete information
    bond investors are not certain abut the true
    level of firm value that will trigger default.
    Coherent integration of structure and uncertainty
    is facilitated with compensators.
  • In reality, default, or at least the moment at
    which default is publicly known to be inevitable
    , usually comes as a surprise. Highlighted in
    credit market by the prevalence of positive
    short-term credit spreads.
  • Features
  • Structure plus uncertainty integrate an
    intuitive, cause-and-effect model with the
    uncertainty that surrounds default events
  • Economic reasonability and flexibility
  • Unified perspective broad enough to incorporate
    intensity based models and traditional structural
    models
  • For tgt0 let F(t) be the prob of default before
    time t. If G(w) is the time of default in state
    w, then F(t) PG(w)ltt which is strictly lt 1.
  • Consider the function A(t) -log(1-F(t)) . This
    is called the pricing trend of the default
    process. The pricing trend can be analyzed
    directly with the mathematical theory of
    compensators
  • The difference btw an underlying process and its
    compensator is a martingale
  • The compensator is non decreasing
  • Compensator is predictable even if underlying
    process is not

26
  • The compensator of the default process is
    continuous iff the default is completely
    unpredictable.
  • Compensators, and thus pricing trends depend both
    on the underlying structure that keeps track of
    the information acquired as time passes.
  • How to create compensators without the
    information structure? use info generated by
    underlying process survival information
    structure
  • Theory can be reworked with an eye to information
    available histories of equity prices, debt
    outstanding , agency ratings and accounting
    variables. Use this information to derive a
    pricing trend from which default probability can
    be estimated.
  • Now we have the conditional probability of
    default by time t, given info at time t as
    F(t,w), which gives the pricing trend as A(t,w)
    -log(1-F(t,w))
  • F(t) 1 - Eexp(-A(t,w)
  • Alternatively, F(t) EF(t,w)

27
  • Model specification
  • Default triggered when the value of firm falls
    below barrier
  • Default barrier is not publicly known
  • The firm value process is given by a geometric
    Brownian motion
  • History of fundamental data and other publicly
    available info used to model the default barrier
    and firm value process
