Financial Accounting for Knowledge Assets
• Accounting rules prevent capture of value– Use of historic costs– Arbitrary cost allocation rules– The conservatism principle leads to
undervaluation of assets– Development of product costs

Value maximization
• Managers objective to maximize firm value
• Value of the firm equals discounted value of all future cash flows
![Page 7: Valuing IT Investments Ken Peffers UNLV October 2004 Ken Peffers UNLV October 2004](https://reader035.vdocuments.mx/reader035/viewer/2022062516/56649d405503460f94a1a581/html5/thumbnails/7.jpg)
Discounted Cash Flow (DCF)
where,NPV = Net Present ValueC = Investment at the start of the projectAt = Cash flow at tT = Project lifer = Risk-based discount rate for the project
![Page 8: Valuing IT Investments Ken Peffers UNLV October 2004 Ken Peffers UNLV October 2004](https://reader035.vdocuments.mx/reader035/viewer/2022062516/56649d405503460f94a1a581/html5/thumbnails/8.jpg)
Firm Value Maximization
where,PV = Present Market ValueAt = Cash flow at tT = Firm lifer = Industry required rate of return
![Page 9: Valuing IT Investments Ken Peffers UNLV October 2004 Ken Peffers UNLV October 2004](https://reader035.vdocuments.mx/reader035/viewer/2022062516/56649d405503460f94a1a581/html5/thumbnails/9.jpg)
Contribution of NPV
• Objective
• Congruence with value maximization
• Better than undiscounted cash flow, simple payback, ROI

Limitations
• Estimates of revenues and costs– manipulated to justify projects already selected
• Biased toward prior opinions• Applied in the face of flawed incentive systems• Assume accurate estimates of future cash flows• Estimations of project risk• Second stage projects• Terminal value

The approachThe approach
• Determine that some parameter among the comparable firms drives value, e.g., the price earnings ratio.
• The firm can be valued at the average P/E for the group of the comparable firms
• Common measures include P/E, market to book ratio, price/revenue ratio

• Value of an IT investment is, in part, based on option to make further investments later
• Right, but not obligation, to make the later investments is similar to an American call option. An American call option confers the right, but not obligation, to purchase a security at a given strike price within a specified time period

Raison D'etreRaison D'etre
• Expected value of a future investment can have a negative value
• DCF method uses discounted expected value• Option to make such an investment can never
have a negative value• Useful when the investment decision can be

Value of Managerial Flexibility
• DCF method assumes 2nd stage projects are undertaken
• Actually won’t be undertaken if value less than 0 at time of investment decision

Value of Managerial Flexibility Example
Value of Managerial Flexibility Example
• The value of a $1.00 investment today will generate either $0.80, $1.10, or $2.00 with equal probability after one year.
• The expected value is ($0.80 + $1.10 + $2.00)/3 - $1.00 = $0.30
• But if the manager can wait until next year to determine whether the cash flow could be $0.80, then next year the expected value will be either $0.30 or $0.55 ($1.10 + $2.00)/2 - $1.00 = $0.55
• The value of the real option to delay the decision is $0.25
• The value of a $1.00 investment today will generate either $0.80, $1.10, or $2.00 with equal probability after one year.

• But if the manager can wait until next year to determine whether the cash flow could be $0.80, then next year the expected value will be either $0.30 or $0.55 ($1.10 + $2.00)/2 - $1.00 = $0.55

The Value of an Option
• In making an initial investment in IT the manager is purchasing an option to make a subsequent investment later if the value of the second stage project is positive
• Of course real problems don’t present themselves with such simple configurations

• Estimating variation. Intuitively: “there is approximately a 2/3 probability that the revenues (costs) will vary up or down by no more than X%)”
• Estimating the corr BC. Intuitively: “approximately X% of the variation in revenues is attributable to variations in the development costs. The remainder is attributable to other factors. The corr BC is the squareroot of X.”
