The Turnover Rent shall be the amount of [emphasis added] which 9% of the Sales Turnover exceeds the Basic Rent.
This sentence (from a retail lease) feels wrong, because this similar sentence requires BY — the Sales Turnover exceeds the Basic Rent BY (not of) 9%. Ought of be BY ? Please elaborate.
Turnover Rent = 9% percent of the turnover of the Tenant's business — Basic Rent.
