However, it is not obvious that the boards would opt to require disclosure on the face, as we propose. This is, in part, because doing so, while arguably being decision useful given their tentative unit of account decision of how to include optional renewal periods in the measurement of the total lease liability, would make salient the recognition of obligations that may not meet the definition of a liability (i.e., ‘‘what-you-may-call-its’’). Nevertheless, we believe our findings (like other ex ante research) will be useful in helping the boards to make these sorts of difficult unit of account choices that often arise during deliberations. In particular, we do so by showing how disaggregation can be used to address informational issues arising from an expansive unit of account choice.
