Why This Is Asked
No verbatim questions or confirmed interview process details are publicly documented for this role at MPIC. This question is grounded in the role's confirmed duties (financial modeling and valuation across infrastructure and utility assets) and tests the candidate's technical knowledge of valuation principles applied to regulated industries.
General Approach
Structure your answer methodically, starting with the purpose of the valuation, then moving through DCF, comparable companies, and precedent transactions. Highlight utility-specific considerations like rate base regulation, cost of equity, and terminal value assumptions.
General Answer
A utility valuation typically combines three approaches: a discounted cash flow (DCF) analysis, a comparable companies analysis, and a precedent transactions analysis, cross-checked against one another. For a regulated water utility such as Maynilad, the DCF should be built around the regulated asset base (RAB) or rate base, since tariffs are usually set by the regulator to allow a fair return on that asset base rather than being pure market-set prices. Free cash flow projections should reflect the concession or franchise term, the periodic rate rebasing cycle, planned capital expenditure for network expansion and non-revenue water reduction, and any foreign-currency debt exposure. The discount rate (WACC) should reflect the lower-risk, regulated nature of the cash flows relative to an unregulated business. Terminal value can be estimated through a perpetuity growth method or an exit multiple, and should be sensitivity-tested against tariff adjustment and demand growth assumptions. Comparable companies analysis would use multiples such as EV/EBITDA or EV/RAB from other listed water or infrastructure utilities, while precedent transactions would look at multiples paid in past utility concession sales, adjusted for differences in regulatory regime and asset age.
PH Interview Gotcha
A common mistake is saying, 'Basta gagamitin ko DCF at comps, pareho lang naman.' This oversimplifies. Instead, explain specific adjustments: 'I would use a DCF with cash flows derived from rate base growth and regulatory assumptions, and select comps based on similar regulatory environments.'
Sample STAR Answer▾
S
Situation
While interning at an investment bank, I assisted in valuing a regional water utility company that was facing a regulatory reset.
T
Task
I had to build a discounted cash flow (DCF) model and perform a comparable company analysis.
A
Action
I gathered historical financials, projected cash flows using rate base growth and allowed return assumptions, and selected comparable water utilities across Southeast Asia. I calculated the weighted average cost of capital (WACC) considering regulatory risk and used a perpetuity growth model for the terminal value.
R
Result
My valuation contributed to a fairness opinion, and the senior banker praised my attention to regulatory details.
Key Takeaway
Understanding the regulatory framework is crucial for accurate utility valuations.
