Recommendations
Our intial recommendation to LIM at this point is to pursue the alternative that involves training UDC to handle Beta failures.
We further recommend a subsequent analysis taking into account much of the information from the first round and assessing the uncertainties.

Decision Hierarchy
• Policy is to be Risk-Neutral in this Range.• Making a profit is the end goal of this exercise.
Selling a product but not making a profit is not a desirable option.
• ROE-II will be sold only for a period of 5 years hence any strategy should be optimized for the next 5 year period.Policy
Strategy
Tactics
To sell ROE-II to UDC or not ?
Eliminate or mitigate the risk associated with servicing that caused the bad experience with ROE-II
Determine the uncertainties early and how they affect the eventual outcome.
Concentrate on evaluating the important uncertainties before making the decision
Attempt to control the important uncertainties by means at our disposal

We can see that in the base case • “Training UDC” is the best option • Contracting with IPX is also an attractive• Existing option is far worse than either training or
contracting

The Key takeaway here is that the “Training UDC” option is the more profitable option in the base case. However the “Train UDC” option also has a higher range (-88, 595) than Contract IPX(0, 347). This “can” imply more risk associated with the “Training WDC” Option

From the tornado diagrams above we observe that. • 4 Uncertainties to be assessed for Alternative 1 (Existing arrangement). • 3 Uncertainties for Alternative 2 (Training UDC for servicing)• 1 Uncertainty for Alternative 3 (Contract with IPX)• Alternative 4(Do not Sell) has no uncertainties

We divided the continuous probabilities into the range {0-25%, 25-75%, 75-100%}.We then arrived at the the values in the table above as the cumulative mean over the individual ranges.We will use these values to further refine our model.

• Alternative 2 (Train UDC) has the best CE and is the initial recommendation if there is no room for further analysis
• We do recommend further analysis on uncertainties to assess their impact and devise plans to control them or mitigate their impact

This graph shows the CDF of the Certain Equivalent of 4 alternatives
Dominance Contd..Type Dominance Exists Comments/Insight
Deterministic No There is always a point where any Alternative X is greater than any other
Alternative Y.Therefore you are never 100% sure that the alternative you select is better than
any other for the entire universe of possibilities
1st Order Yes“Train UDC” Dominates “Existing Option”
This implies that “Train UDC” is a better alternative than the “Existing” alternative
over the entire probability space.We can discard “Existing” option for
further analysis for almost all practical cases (See note on slide)
2nd Order Yes“Train UDC” Dominates “Contract with IPX”
and “Do not Sell”“Contract IPX” Dominates “Do not Sell”

• Similarly $14.31K for information on “Units Sold” and $6.28K for Alpha failures

Conclusions
Items for a second-round assessment Determine Value of Information and VoC for multiple degrees
e.g (Units Sold & Training Cost) Identify tools that can effectively provide Control or Information
on the uncertainty parameters and evaluate their effectiveness.
Revaluate Risk-Preference Study if options be used as a tool to mitigate risk ? Instead
of Contracting with IPX, buy the option to contract with IPX. Evaluate an insurance purchase for uncertainties that cannot
be controlled.
