In addition, subject to certain limitations, the company may reduce the notional number
of Class A shares underlying the Total Return Equity Swap transaction prior to the transaction's maturity.
These nouns raise an obvious question: If English allows you to assign plural or singular status to a noun according to its notional number
, shouldn't these words should be treated as plurals?
But in fact, not only is there a general tendency in English to use a singular verb after there, but the notional number
of the phrase also suggests it should be treated as a singular verb.
