A 2015 assessment concerned a proposed acquisition of an advisory business with 180 client relationships. The initial strategic narrative emphasised access to a larger business-customer population. That was plausible as a starting question, but the relationship count did not itself establish additional reach. Our comparison identified 112 relationships already represented in the bank's existing customer base. Sixty-eight were not matched in that exercise. The proposal needed to distinguish those groups before using the total to support its strategic rationale.
The sponsoring team argued that overlap could strengthen relationships and create a deeper proposition for existing customers. I agreed that a repeated relationship was not necessarily worthless. My objection was to presenting the same relationship as incremental reach while also claiming a benefit from serving it more fully. Those were different arguments with different evidence. Neither could be settled by treating all 180 names as a single addition to the bank's addressable customer population.
I recommended that the strategic case be reconsidered without the unsupported new-reach claim. The sixty-eight unmatched relationships were not assumed to become bank customers, and no conversion rate was invented to preserve the original attractiveness. Financial, legal, risk and transaction specialists retained their responsibilities. My role was to examine the reasoning about institutional fit and the choices available, not to determine a valuation or substitute a strategy opinion for diligence in those disciplines.
We did not complete the proposed transaction. C$740, 000 in diligence expense remained a cost of reaching that conclusion. Some colleagues felt the expenditure made withdrawal harder to defend, particularly after the proposal had occupied management attention. I argued that the cost already incurred should be disclosed, but that disclosure did not make an unsupported rationale stronger. Continuing merely to avoid explaining the expense would have confused the record of the assessment with the merits of the decision still ahead.
The lesson I retained was about the language of reach. Relationship overlap may matter positively, negatively or differently from the original proposition, but it has to be described on its own terms. I do not present the rejected transaction as a quantified loss avoided because that counterfactual was not established. The case shows a recommendation that changed after the evidence narrowed what we could responsibly claim, with the unused opportunity and the assessment cost left visible.
