Time Value of Money Because money can earn interest, it has a value dependent on time Assume we can get 10% annual interest Which of the following is the best option?
Now $100
1 Year $105
2 Years $120
The amount matters, but so does the time that the money will be received or spent.
Future Value Future value is the value in the future of an amount of money currently held Future value is calculated by compounding the present amount by a rate that accounts for the time value of money
FV = PV (1+i)n
Future Values FV = PV (1+i)n At the 10% interest rate Now $100
=
1 Year $110
=
2 Years $121 Future Value (FV)
Future values are worth less than present values of an equal sum
The second year, the interest was more than from the first year $10 and $11 Compounding
Compound Interest When interest is earned on the amount originally invested plus on interest previously earned, it is called compound interest Evaluations in Canada use the principle of compound interest
FV: Compound Interest N
Year
1
Year 1
FV1 = P(1+i)
2
Year 2
FV2 = P(1+i) (1+i)
3
Year 3
FV3 = P(1+i)(1+i)(1+i) or FV3 = P(1+i)3
4
Year 4
FV4 = P(1+i)4
n
Year n
FVn = P(1+i)n
Interest is paid at the end of each period
Formula
FVn = Value of Savings Bond P = Principal i = Interest Rate
FV: Compound Interest N
Year
Calculation
1
Year 1
A1 = $1000(1+0.1) = $1100
2
Year 2
A2 = 1000(1+0.1) (1+0.1) = $1210
3
Year 3
A3 = $1000(1+0.1)(1+0.1)(1+0.1) or A3 = $1000(1+.1)3 = $1331
4
Year 4
A4 = $1000(1+.1)4 = $1464
7
Year 7
A7 = $1000(1+0.1)7 = 1949
Future Value Example Future value of $1,000 in 7 years at 10% interest rate FV = PV(1+i)n n = 7, i = 10% (0.10), PV = $1,000
FV = $1,000x(1+.10)7 = $1949
Present Values At the 10% interest rate Now $100 Present Value (PV)
1 Year $110
2 Years $121 Future Value (FV)
Future values are worth less than present values of an equal sum
To properly value a cash flow stream, we need to determine valuation at a common point in time Called “Present Value” (PV)
Present Value Present value is the current economic equivalent of an amount of money to be received in the future Present value is calculated by discounting the future amount by a rate that accounts for the time value of money FV = PV (1+i)n
PV = FV/(1+i)n
Discount factor = 1/(1+i)n
Present Value Example What is the present value of $1,000 to be received 7 years from now with a 10% interest rate PV = FV/(1+i)n n = 7, i = 10% (0.10), PV = $1,000
PV PV PV PV
= = = =
$1,000/(1+.10)7 $1,000 * (1/1.949) $1,000 * 0.513 $513

The discount factor is equal to 1/(1+i)n DF(1) = 1/(1+0.10)^1 = 0.909091 remember the first period is “1”
Discounting Discounting Reducing a sum of money in the future to determine its equivalent value now. Commonly done by using a discount factor. 1/(1+i)n Assumes that the cash flows occur at the end of the year. What if the cash flows will occur throughout the year?
Mid-Year Discounting Oil companies receive cash monthly Discounting monthly cash flow to the end of the year underestimates the value of the cash received before December A better approximation is to assume that the cash is collected in the middle of the year
Mid-year vs. End-year Discounting
Present Value Present Value (end-year) PV = FV (1+i)n Present Value (mid-year)
PV = FV (1+i)n-0.5

What discount rate to use? Primary goal of a company: create value for shareholders Typically through value add projects Value determined by future cash flows Current value of a company is determined by the value of its anticipated future cash flows Need to calculate PV of future cash flows Need to use a discount rate to do so Appropriate discount rate determined by a company’s cost of capital
Cost of Capital Cost of raising funds Debt
Interest rate required by lenders
Equity
The return required by investors
Key driver of firm value If a company can reduce its cost of capital all potential investments become more attractive The required rate of return on firm’s investments in order to satisfy all investors
Weighted Average Cost of Capital (WACC) Company Capitalization = Debt + Shareholders’ Equity WACC = (WD * (1-TR) * KD + WSE * KSE) ; where
WD = % Capitalization that is Debt TR = Tax Rate KD = Cost of Debt WSE = % Capitalization that is Shareholder Equity KSE = After Tax Return on Shareholder Equity
Cost of Capital
Interest rate required by lenders
Determined by the terms of the loan
The return required by investors Basically what it costs the company to maintain a share price that is satisfactory (at least in theory) to investors Theoretical methods exist to calculate an approximation of what the market expects Capital Asset Pricing Model (CAPM) Setting an actual target Arbitrary decision by Board of Directors

Use of Profitability Indices Analyze investments Determine whether an investment will meet a profitability threshold Determine how much profit an investment will make Compare investments Decide which investment opportunities to pursue and which to defer or reject Rank investment opportunities Create budgets – top down then bottom up cycle Decide whether to make substitutions on budgeted projects Reduces ranking subjectivity

Profit to Investment Ratio (PIR) (Return on Investment) Total net profit divided by the investment Determined by: Calculate the total net cash flow Calculate the total investment Divide the total net cash flow by the total investment Assesses the risk that the project might not payout if prices decline or if production is lower than forecast “Bang for your buck” Ignores time value of money
Discounted Profit to Investment Ratio (DPIR) (Discounted Return on Investment) Ratio of the NPV of the cash flow to the NPV of the investment Capital efficiency metric Determined by: Divide the NPV by the NPV of the investment at similar discount rates Often used to rank investments Ensures portfolio generates maximum NPV for the company Considers time value of money

Internal Rate of Return (IRR) The internal rate of return (IRR) is the discount rate at which the NPV of the cash flow is equal to zero IRR can be described as the rate of growth a project is expected to generate Determined by: Determine the net present value of the cash flows using various discount rates until the net present value equals zero. Practically, use interpolation (Goal Seek in Excel) to find the rate at which the net present value equals zero Used as a threshold indicator Companies generally do not invest in projects that have a IRR less than their cost of capital Considers time value of money

Which Project is the Best Investment Opportunity? – Project B
Operating Netback How much money is being made per unit of production
Operating Netback = (Revenue – Royalties – Opex) Production
Strength: easy to calculate Weakness: Doesn’t consider the time value of money Doesn’t consider asset type; not neutral
Finding & Development Costs (F&D) Cost of adding a unit of new reserves
F&D = Capital to find & bring reserves on production Reserves Added
Can be calculated for any basis Total Proven F&D Total Proven plus Probable F&D PUD F&D Current year capital program F&D Corporate 3 year average F&D
Recycle Ratio Netback/F&D Ratio of profit to cost For each BOE produced, profit vs. cost to replace The higher the recycle ratio the more profitable the company
Doesn’t consider the time value of money Uncertainty in what is included in F&D costs
Reserve Life Index Ratio of reserves to current production Reserve Life Index (RLI) = Reserves Current Production Strength: Useful check Used for assessing risk Weakness Doesn’t consider asset type (heavy oil production incline, horizontal steep 1st year production decline)
Profitability Indices There is no perfect profitability index All have strengths and weaknesses Selecting the appropriate profitability indices to use for analyzing and ranking investments requires experience and good judgment Proper analysis of projects is the key to ensuring corporate goals are met
