Q

What are the adjustments to convert LIFO inventory to FIFO inventory?

A
BALANCE SHEET
Inventory = Inventory + LR
Cash = Cash - (LR x tax rate)
Equity = Equity + [LR x (1-t)]
i.e. Adjusting assets = add LR net of tax

Income Statement
COGS = COGS - change in LR
Tax Expense = Taxes + (change in LR x tax rate)
Net Income = NI + [change in reserve x (1-t)]

*adjusting equity and net income are the same, just using the LR vs the change in LR

Q

Key differences between capitalizing R & D and Software

A

Research and Development (R & D)
IFRS: R = expense D = capitalize
GAAP: R & D = expense

Software developed for sale:
IFRS & GAAP: expensed until feasibility is reached

Software developed for internal use
IFRS: expensed until feasibility is reached
GAAP: capitalized all software development cost

Q

Impairment

A

IFRS: BV > Recoverable Amount (write down to greater of FV - selling cost or PV of future cash flows) & allow loss reversal

GAAP: BV > undercounted cash flows (write down to fair value - or discounted future cash flows) only assets not held for use are allowed to reverse impairment

*DO NOT AFFECT CASH FLOW (non cash charge)

**Impairment means an asset was not depreciated fast enough

Q

Adjusting an operating lease into a financing (capital) lease:

A
  1. Lower of fair value or PV of future lease payments is reported as an asset and liability
  2. Asset is depreciated
  3. Interest expense is recognized on liabilty
  4. Lease payments like amortizing debt - each payment is part interest (CFO) and part principal (CFF).

Calculate IRR to determine implicit rate (us PV of future minimums as the outflow, and then use the payments as inflows)

SIMPLIFIED

  1. Increase A & L’s by PV of remaining lease payments
  2. Remove rent expense from I/S and replace with depreciation and interest expense

IFRS: permits partial also

Full goodwill = total fair value of subsidiary minus FV of net identifiable assets and

Minority interest = % not owned times total fair value of subsidiary
_______________________________

Partial goodwill = purchase price of partial interest minus the % owned times FV of net identifiable assets

Minority interest = % not owned times fair value of net identifiable assets

Q

FCFE vs FCFF

A

FCFE: use when capital structure is stable
FCFF: when high or changing debt levels or negative FCFE

53
Q

FCFF Formulas

A
FCFF = NI + NCC + INT ( 1 - t ) - WC - Net Capex
FCFF = CFO + INT ( 1 - t ) - Net Capex
FCFF = EBIT ( 1 - t ) + NCC - WC - Net Capex
FCFF = EBITA ( 1 - t ) + NCC ( 1 - t ) - WC - Capex
  • ( 1 - t ) = pre leverage
54
Q

FCFE Formulas

A
FCFE = NI + NCC - WC - Net Capex + Net Borrowings
FCFE = CFO - Net Capex + Net Borrowings
FCFE = EBIT ( 1 - t ) - Int ( 1 - t ) + NCC - WC - Net Capex + Net Borrowings
FCFE = EBITDA ( 1 - t ) - Int ( 1 - t ) + NCC ( t ) - WC - Net Capex + Net Borrowings
  • POST LEVERAGE
55
Q

WHY Net Income is a poor estimator for FCFE

A
  1. NI is an accrual concept not cash flow
  2. NI recognizes noncash charges
  3. NI Fails to recognize cash flow impact of investments in working capital, capex, net borrowings
56
Q

EBITDA is a poor estimate for FCFF

A
  1. does not reflect taxes paid
  2. ignores effect of depreciation tax shield
  3. does not account for needed investments in WC and net fixed assets
57
Q

Calculating Underlying Earnings

A
  1. Remove gain/losses on asset sales
  2. Remove asset write-downs (impairments)
  3. Remove loss provisions
  4. Remove Changes in accounting estimates
58
Q

Calculating Normalized Earnings

A

Remove cyclical component with either of two methods:

  1. historical average EPS
  2. average ROE (preferred)

Average ROE = take arithmetic average and multiply by latest BVPS (book value per share)

59
Q

Problems with PEG ratios

A

DO NOT ACCOUNT FOR:

  1. differences in firm risk attributes
  2. differences in the duration of growth
  3. Nonlinear relationship between growth and P/E ratio
60
Q

Drawbacks of a P/B ratio

A
  1. does not reflect value of intangibles
  2. misleading when comparing firms with significant differences in asset size
  3. Different accounting conventions make it difficult to compare
  4. Inflation and technological change can cause big differences between BV and MV
61
Q

P/B Formulas

A

P/B = MV Equity / BV of Equity

Justified P/B = (ROE - g) / ( r - g )

62
Q

P/S Drawbacks

A
  1. High sales growth does not translate to operating profit
  2. P/S does not capture different cost structures between firms
  3. Revenue recognition methods can distort reported sales and forecasts
63
Q

P/S Formula

A

Is same as trailing P/E and simply is multiplied by current period profit margin

= Margin x payout x growth / cap rate

64
Q

P/CF Drawbacks

A
  1. Ignores some NCC, WC, Capex, Net Borrow
  2. FCFE is preferable to CFO but FCFE is more volatile and difficult to compute
  3. FCFE can be negative with large capex
65
Q

P/CF Justifed

A

Vo = FCFEo (1 + g) / r - g

then take Vo / CF

Will increase if required return decreases

66
Q

EV / EBITDA

A

Pros:

  1. Comparing firms with different financial leverage since EBITDA is pre leverage
  2. Controls for D & A differences
  3. EBITDA usually positive when EPS is negative

Cons:

  1. Ignores changes in WC
  2. FCFF is more closely tied to value because it controls for CAPEX
67
Q

Justified Dividend Yield

A

Do / Po = ( r - g ) / ( 1 + g )

*Factors affecting dividend yield are opposite of other ratios.

Dividend yield increases when:

  1. required return increases
  2. High growth decreases payout
  3. high D/P strategy
68
Q

Residual Income Models

A

= same as economic profit

POST LEVERED
RI = NI - (BVo x Ke)

PRE LEVERED
RI = EBIT ( 1 - t ) - (Total Capital x $WACC)

69
Q

Alternative RI Measures

A

EVA = EBIT ( 1 - t ) - (Invested Capital x $WACC)

MVA = MV of Firm - invested Captial

70
Q

Calculating Future RI

A

TWO METHODS for Calculating Future RI

  1. RI = EPS - (r x BVt-1)
  2. RI = (ROE - r) x BVt-1

OR

[(ROE - r ) / (1 + r)] x Bt-1

71
Q

RI Valuation Models

A

SINGLE STAGE

Vo = Bo + [ ((ROE - r) x Bo) / (r - g) ]

72
Q

Continuing Residual Income

A

IF:

w = 0, no competitive advantage
w = 1, perpetual competitive advantage (perpetuity)
0 < w < 1 = decline over time to zero

The w simply goes after the (1 - r) in the denominator of the formula

73
Q

Adjustments to make when valuing a private company

A
  1. Nonrecurring and unusual items
  2. Discretionary expenses
  3. Non market compensation levels
  4. Personal expenses
  5. Real estate expenses
  6. Non-market lease rates
  7. Strategic vs non strategic buyers
74
Q

Capitalized Cash Flow Method (valuing private companies)

A

Firm = FCFF / WACC-g

Equity = FCFE / r - g

75
Q

Excess Earnings Method

A

EE = Normalized earnings - Return on WC - Return on Fixed Assets

76
Q

Discount for Lack of Control (DLOC)

A

DLOC = 1 - [ 1 / ( 1 + Control Premium ) ]

Total Discount = 1 - [ (1 - DLOC) x ( 1 - DLOM)]

*Income tax and interest expense are not operating expenses

78
Q

Cost Approach to valuing real estate

A

Land cost + construction cost - economic depreciation

79
Q

NCRIEF Property Index

A

Capital Return = [(change in mkt value - capex) / beg mkt value]

Return = [(NOI - capex + (end mkt value - beg mkt value)) / beg mkt value]

Holding Period Return = NOI / beg mkt value = Current yield = income yield = cap rate

80
Q

Real Estate financial ratios

A

DSCR = first-year NOI / debt service

LTV = loan amount / appraisal value

Equity dividend rate = NOI - debt service / equity

81
Q

Private Equity Calculations

A

NAV before distributions = previous year NAV after distribution + called capital - management fee + operating results

NAV after distributions = NAV before distributions - carried interest - distributions

Distributed to PIC (DPI) = LP realized return = cumulative distributions / paid in capital

Residual value to PIC (RVPI) = LPs unrealized return = NAV after distributions / paid in capital

Total Value to PIC (TVPI) = realized and unrealized returns = DPI + RVPI

  1. Selection: choosing not to report
  2. Backfill: incubation
  3. Survivorship: bad ones fall out
84
Q

Nonnormality in Return Distribution

A

Hedge funds have:

  1. Negative Skew
  2. High kurtosis

*Std Deviation is unsuitable

You PREFER THE OPPOSITE

85
Q

Convenience Yield and Inventory Level

A

High inventory = lower CY and lower Futures Price

86
Q

Forward price of a commodity

A

FPo = Soe^( r + U - Y ) t

r = Rf
U = cost of storage (% of commodity price)
Y = CY
87
Q

Backwardation & Contango

A

Backwardation will result in a positive roll yield

Contango will result in a negative roll yield

Normal backwardation: occurs when producers hedge using futures

88
Q

Make-up of Commodity Futures Portfolio Return

A
= spot 
 \+ roll return
 \+ collateral return
 \+ rebalancing return
 = total return

Excess Return = spot + return returns

Total Return = collateral + futures

89
Q

Theories of commodity returns

A
  1. Insurance: speculators earn premium from short hedgers
  2. Hedging pressure: depends on the balance of hedgers to short or long side
  3. Theory of storage: difficult to store = positive CY
90
Q

Measures of Credit Risk

A

Loss Given Default (LGD): % of principal and interest lost if borrower defaults

Expected Loss (EL) = Probability Of Default (POD) x LGD

PV of EL = highest price investor would pay to an insurer to bear the credit risk of the investment

MAKES 2 ADJUSTMENTS

  1. Time value of money (duh)
  2. Uses Risk-Neutral Probability (RNP) instead of POD to account for the risk of the cash flows
91
Q

STRUCTURAL MODEL BACKGROUND

A

Shareholders have a call option on the company’s assets with the Face Value of debt as the strike price.

Value of Risky Debt = Value of Rf Debt - Value of a put option on the company’s assets

92
Q

STRUCTURAL MODEL ASSUMPTIONS

A
  1. Assets are traded in a frictionless and arbitrage free environment
  2. The Rf rate is constant
  3. Only zero-coupon bonds
93
Q

STRUCTURAL Strengths / Weakness

A

STRENGTHS

  1. Uses option pricing theory to understand POD & LGD
  2. Inputs can be estimated using current market prices

WEAKNESSES

  1. Only uses zero coupon bonds
  2. Company assets are not actually traded, hence not directly observable
  3. Estimation procedures do not consider business cycle
94
Q

REDUCED FORM ASSUMPTIONS

A
  1. Company has a zero-coupon bond liability that trades in a frictionless market
  2. the Rf rate, economy, POD, and recovery rate are non-constant
95
Q

REDUCED FORM STRENGTHS & WEAKNESSES

A

STRENGTHS

  1. Model can be estimated using historical data
  2. Credit risk is allowed to fluctuate with the cycle
  3. No need to specify company’s B/S

WEAKNESSES
1. Past market conditions do not reflect future estimates

96
Q

Formula for PVEL

A

= max amount an investor would pay an insurer to bear the credit risk of a risky bond

PVEL = Value of risk free bond - value of credit risky bond

97
Q

KEY RATE DURATION

A

Change in Key Rate Duration = - D x Key rate

98
Q

SPREAD MEASURES

A
  1. Z-spread: spread added to each rate on spot rate curve that makes PV of bond CFs equal to market price (difference between theoretical sport rate curve and the market)
  2. Option Removed Spread: spread added to each rate in binomial interest rate tree that makes bond value calculated from binomial equal to market price
    * OAS = Z-Spread - cost of embedded option

** WANT OAS HIGH

99
Q

Valuing Embedded Options

A

Value of Call = Vnoncallable - Vcallable

Value of Put = Vputable - Vnonputable

IF: Rate volatility incresases

THEN: Value of embedded call increases, value of callable bond falls

100
Q

Effective Duration Formulas

A

ED = (BV-y - BV+y) / (2 x BVo x change in y

EC = [(BV-y - BV+y - (2 x BVo) / (2 x BVo x change in y^2)

101
Q

CONVERTIBLE BONDS = call option on stock

A

Conversion Ratio (CR) = number of share per bond

Market conversion price (MCP) = Effective price per share when converting

Conversion Value (CV) = Market price of stock after conversion x CR

Favorable income difference = (ann $ coupons - [CV ratio x ann. divs]) / CV Ratio

Premium over straight value = (MV of bond / straight value) -1

Premium payback period = = market conversion premium / favorable income difference

102
Q

Callable Convertible Bond

A

CCBV + call on bond = straight bond + call on stock

IF stock volatility increases = call on stock increases
IF rate volatility increases = CCBV goes down and call on bond goes up
IF rates increase CCBV and straight bond go down

103
Q

Single Monthly Mortality Rate

A

SMM = 1 - (1-CPR)^(1/12)

100 PSA = 0.2% per month up to 6%

200 PSA = 2x CPR

104
Q

Factors affecting Mortgage Prepayment

A
  1. Prevailing Mortgage Rates (most important)
  2. Housing turnover
  3. Characteristics of underlying mortgages (seasoning and locations)
105
Q

Collateralized Mortgage Obligations (CMOs)

A
  1. Basic Sequential pay
    - all tranches receive interest
    - shortest tranche receives all principal until paid off
    - Z-tranch or accrual tranche receives NO payments until sequential pay tranches are serviced BUT interest accrues as additional principal
  • Z tranche bears the most extension risk and the lowest contraction risk
  1. PAC CMO: guaranteed principal payments based on sinking fund schedule
    - the Support Tranches bears the contraction and extension risk
106
Q

CONTRACTION & EXTENSION RISK

A

CONTRACTION: avg life decreases as rates fall and prepayments increase

EXTENSION: avg life increases as rates rise and prepayments fall

107
Q

Stripped Mortgage Back Securities

A

Principal Only (PO) win if rates fall

Interest Only (IO) win if rates rise

108
Q

MBS SELECTION

A

BUY CHEAP: big OAS, low option cost

SELL RICH: small OAS, high option cost

109
Q

Analyzing Interest Rate Risk

A

% Change in bond price = duration effect + convexity effect

= -ED x change in y x 100 + EC x change in y^2 x 100

110
Q

Pricing a forward contract

A

FP = So x ( 1 + Rf)^T

111
Q

Cash and Carry

A

IF forward price is too high:

  1. Borrow and buy bond today
  2. Short the forward and reap the reward

REVERSE

  1. Short the bond (receive proceeds)
  2. Invest proceeds at Rf rate
  3. Go long the forward
  4. Cover the short and reap the reward
112
Q

Valuing a forward contract

A

V1 = St - [FP / ( 1 + r )^( T - t )]

113
Q

Pricing an equity forward contract (same for fixed income)

A

FP = (So - PVD) x ( 1 + Rf)^T

114
Q

Valuing an equity forward contract (same for fixed income)

A

Vt = (St - PVD) - [FP / ( 1 + Rf)^(T-t)

115
Q

Pricing Index Forward Contracts

A

FP = So x e^((Rf - Div) x t)

116
Q

Valuing Index Forwards

A

Vt = (St / e^(Div x (T-t)) - (FP / e^(Rf x (T-t))

117
Q

Forward Rate Agreement (FRA)

A

FRA = agreement to borrow or lend in the future
i.e. “2 x 3” = FRA price = implied 30-day forward rate 60 days from now

  • Can be replicated wit ha long interest rate call + a short interest rate put
118
Q

Valuing currency forwards

A

Vt = [St / (1 + Rfc)^(T-t)] - [FT / (1 + Rdc)^(T-t)]

119
Q

Treasury Bond Futures Contracts

A

FP = [bond price x (1 + Rf)^T - FVC] x 1 / CF

CF = cash flow of cheapest to deliver bond

120
Q

European Put-Call Parity

A

C - P = S - PV(X)

121
Q

OPTIONS AND BINOMIAL MODEL

A

Probablities are not 50/50

Probabilty of Up Move = 1 + Rf - size of down move / (size of up minus size of down)

122
Q

Calculate the value of an option using an interest rate tree:

A

Step 1: Price the bond at teach ending node in the interest rate tree
Step 2: Calculate terminal value of option at each ending node in tree
Step 3: Discount expected terminal option values back through tree

123

  2. Known and constant volatility assumption is unrealistic
  3. Less useful with taxes, transaction costs
  4. Doesn’t price American options
125
Q

The Greek Risks

A
  1. S (asset price) = Delta
  2. volatility = Vega
  3. Rf = interest rate = (Rho)
  4. T = tie to expiration = (Theta)
  5. X = exercise price
126
Q

GAMMA

A

rate of change in delta as stock price changes

  1. largest when option is at the money and close to expiration
  2. Use in and out of the money options not close to expiration to reduce trading costs
127
Q

AFFECT OF CASH FLOWS ON UNDERLYING ASSETS

A
  1. Reduce call values

2. Increase put values

128
Q

Assumption of the Market Model

A
  1. e = 0
  2. The return on the market portfolio is not correlated with the error term
  3. The error terms are uncorrelated across securities
    * e = unsystematic risk or diversifiable risk
