A. Overdraft Limit
The Facility enables you to overdraw the Facility Account up to the Overdraft Limit. The Overdraft Limit should not be exceeded without our prior consent and we may refuse to allow any payment or withdrawal which could have that effect. If we allow a payment or withdrawal or a series of payments or withdrawals which results in the Overdraft Limit being exceeded, it will not mean that the Overdraft Limit has changed or that we are bound to allow any other payment or withdrawal which could result in the Overdraft Limit being exceeded at other times.
We may debit the Facility Account under Clauses D and E of these COGT even if it results in the Overdraft Limit being exceeded.
