Equity and Financial Concepts

Free Cash Flow (FCF)

FCFt = EBIT + DEP - CAPEX - ΔWC - TAX

ΔWC = Δreceivables + Δinventories - Δpayables + Δother items

TAX = (EBIT-Yt)*T = EBIT*T - YtT

FCFE = FCFt - Yt - PRINCt

FCFtu = FCFt - YtT

Y = kdD0 (interest paid is cost of debt*value of debt)

Standard WACC

ks=(1-L)ke + Lkd(1-T) | Use Standard WACC with FCFu | ITS is not included in both FCFu & ks | Need Constant Target Leverage Ratio (L)

ke = reflects operating and financial risk faced by investors | ku = unlevered cost of equity (if firm had no debt), reflects operating risk

V0 = U0 + I0 (Enterprise Value = value of operations + value of ITS) | Leave space for Standard WACC equation if kits = kd OR kits = ku

Standard WACC model implicitly assumes kits = ku | V0 = U0 + I0

Vanilla WACC

kv = (1-L)ke + Lkd | Use Vanilla WACC with FCFt | ITS is included in both FCFt & kv | Need to know value of debt at start of each period - use Vanilla WACC with target debt schedule | STANDARD WACC AND VANILLA WACC: ks = kv - kdTL

If kits = kd: if kits = ku:

Approximation error: ITS is dependent on future debt levels, just ask risky as firms debt so should be valued discount rate kits = kd BUT Vanilla WACC assumes kits = ku so kv = ku since approximation error is small

Recursive Standard WACC

Discount Rates

Fama French 3 Factor: E(MRP): Market Risk Premium | E(SMB) Size Premium | E(HML) Value Premium

Investors expect higher returns on: small stocks (relatively small market value of equity) & value stocks (high Book Equity/Market Equity, B/M, ratios, low P/E ratios, low growth rates) - compared to big stocks and growth stocks (low B/M ratios, high P/E, high growth rates)

Total risk to determine expected cash flows, only systematic risk for determining discount rates

Cost of Debt:

y = rf + Credit Spread

If debt is risk free or not "too risky": kd = y = rf + Credit Spread | Appropriate assumption for investment grade debt rated BBB or better

Miscellaneous Issues

Surplus Assets:

cash, unused land or properties, investments in financial securities such as shares in unrelated companies, joint ventures, other non consolidated investments

Non-Consolidated Entities:

joint ventures, equity investments etc. : Firms investment in other entities which it does not control

Non-Controlling Interests:

subsidiary (or other entity in group) is controlled by the firm, consolidated financial statements, but less than 100% owned by firm. Represents external claim on FCFE generated by subsidiary. V0 and E0 will include value of non-controlling interest

V0 = Vex0 + S0 = D0 + E0 + N0 where S = value of surplus assets, N = value of non-controlling interests

Vex0 = D0 + Eex0 where Eex0 = E0 - S0 equity value excl. surplus assets

One-Off Items:

Income or expenditure item included in FCF which is not expected to arise again in future period

Corporate Taxes:

Estimate FCF assuming whole of EBIT is subject to tax at statutory corporate tax rate T

Leases:

If you treat lease as equivalent to debt, use FCF before lease payments & add lease liability to debt in calculating cost of capital

If you do not treat the lease as equivalent to debt: use FCF after lease payments & do not add lease liability to debt in calculating cost of capital
