Synergies, excerpt p.6
Several interesting points here. Hopefully the "second school of thought" rules the day.
"I. Valuing Operating Synergies
There is a potential for operating synergy, in one form or the other, in many
takeovers. Some disagreement exists, however, over whether synergy can be valued and,
if so, what that value should be. One school of thought argues that synergy is too
nebulous to be valued and that any systematic attempt to do so requires so many
assumptions that it is pointless. If this is true, a firm should not be willing to pay large
premiums for synergy if it cannot attach a value to it. The other school of thought is that
we have to make our best estimate of how much value synergy will create in any
acquisition before we decide how much to pay for it, even though it requires assumptions
about an uncertain future. We come down firmly on the side of the second school.
While valuing synergy requires us to make assumptions about future cash flows
and growth, the lack of precision in the process does not mean we cannot obtain an
unbiased estimate of value. Thus we maintain that synergy can be valued by answering
two fundamental questions.
(1) What form is the synergy expected to take? Will it reduce costs as a percentage of
sales and increase profit margins (e.g., when there are economies of scale)? Will it
increase future growth (e.g., when there is increased market power) or the length of
the growth period? Synergy, to have an effect on value, has to influence one of the
four inputs into the valuation process – higher cash flows from existing assets (cost
savings and economies of scale), higher expected growth rates (market power, higher
growth potential), a longer growth period (from increased competitive advantages), or
a lower cost of capital (higher debt capacity).
(2) When will the synergy start affecting cash flows? –– Synergies seldom show up
instantaneously, but they are more likely to show up over time. Since the value of
synergy is the present value of the cash flows created by it, the longer it takes for it to
show up, the lesser its value."
