What does "Delayed payment charges" entry on the funds statement mean?

Cash Requirement for F&O:
Exchanges mandate that 50% of the margin for F&O positions must be in cash or cash equivalent collateral.
The remaining 50% can be in non-cash collateral margin.

Delayed Payment Charge:
If there’s a shortfall in the cash margin requirement for overnight positions and it’s funded by non-cash collateral, a delayed payment charge of 0.035% per day applies on the cash margin shortfall.
