41 I turn to the first of the "key outstanding areas" identified by Ms Armstrong in par 13.1 of her affidavit, namely, the need for a detailed analysis of the increase in the work in progress (WIP) from $473,000 as at 30 June 2001 to $1.1 million as at 30 June 2002. She says the fact that the work had doubled within one year is significant. She requested further information to determine if production had increased for the purposes of meeting a demand, alternative, whether or not there had been a change in the standard costing system over the two financial years. She says the value of WIP is a factor that impacts on the overall assessment of the profitability and value of the assets of the company. Job cost sheets referred to in her facsimile to Pasdonnay of 8 August 2002 were requested as one method to assess whether the increase in the value of the WIP was attributed to a significant change in standard costing, and to assist in determining if its book value reflected accurately the true value of WIP. In answer to this proposition, the defendants rely, in essence, on what Mr Buckingham says in his report by way of summary and response. He says he understands that Deloittes has been provided with a report, outlining the total WIP by job number, and that this report agreed with the general ledger as at 30 June 2002. Additionally, he understands that the sale agreement will allow for a full stocktake of WIP to be attended by representatives from Deloittes and SDS on completion date. The results of this stocktake will determine the purchase price to be paid for stock, including WIP, under the agreement. He says it is difficult, therefore, to understand the purpose of the request. As to the movement in WIP from 30 June 2001 to 30 June 2002, it is said that this has already been explained by Mr Gilbert of Pasdonnay to Mr Benson of SDS. He also says that, before the sale is completed, another stock count is to be conducted. The defendants contend, therefore, that any movement in WIP from 30 June 2001 to 30 June 2002 would not have any bearing on the purchase price of the business and thus it is difficult to understand why any further explanations on the movement are necessary. The particular issue concerning the movement in WIP is the subject of item 7 of the letter from Deloittes to Mr Geoff Brennan of Thomson Playford, which is attachment RAA5 to the affidavit of Ms Armstrong.
