We still have not received the remaining portion of the documents/information requested. As it has been delayed for quite some time, to avoid any further delay we have prepared a demand notice draft and computation spreadsheets by making some assumptions on missing information. Please take a look at the draft and the computation spreadsheet to see whether we got numbers and facts right or not. If any number or facts is incorrect or inaccurate in any aspect, please kindly correct us. Obviously, there seems to be an inconsistency between your previous demand notices and the Written Acknowledgment of Claim. If they look right to you, you may want to confirm the draft so that we can send to the counterparty.
