However, if the collateral ratio subsequently falls short again on any given business day, and the customer fails to take the initiative to pay additional collateral on that same day, dispose of its collateral beginning on the next business day under the mutatis mutandis application of Article 32, paragraph 1.
3. If before the collateral has been disposed of under the preceding subparagraph, the sum of any successive collateral deposits made by the customer covers the shortfall of which it was notified, expunge the collateral call record.
