38 Mr Macpherson's affidavit revealed that on 2 February 2010, the Bank wrote to Garuda's representative referring to the Loan Agreement and to the fact that the value of the aircraft had reduced and that as a result, a top up amount of US$10.35 million was payable. The Bank offered Garuda an alternative to making the top up payment to reduce the loan balance. That alternative was to provide US$10.35 million as additional security in which case no break costs would be payable. There was no written reply by Garuda to the Bank's offer. Nothing happened until May 2010 when there was then an exchange of emails in which the Bank informed Garuda that the break costs payable as a result of the required top up payment of US$10.35 million were 'in the order of US$900,000'. Later emails reveal that the amount paid was AUD$945,000. It was therefore clear that the Bank's offer concerning the payment of additional security was not accepted. The US$10.35 million was paid in reduction of the loan amount. The affidavits did not depose exactly when the payment of $945,000 was made, but it was accepted by the parties that it was paid and it may be assumed that the payment was in May 2010. The break costs were the costs to the Bank of unwinding an interest rate hedge. It is clear that the payment of $945,000 was paid by Garuda as break costs in relation to the payment of US$10.35 million. Garuda did not purport to pay the $945,000 as a reduction of the principal debt of US$27 million.
