Issue 3 - hourly rate of actual FTM1000 during period of assessment
21 This issue concerns the average hourly charge out rate to be inputted for the calculation of the profits of the actual FTM1000. The parties agree that one hourly rate should be used for the whole relevant period (that is, from 25 July 2017 until 3 November 2024). That rate, together with the shift utilisations of the FTM1000 outlined in issue 2 above, will determine the estimated actual profits made by the FTM1000 for the purpose of this assessment.
22 Ezy-Fit submitted the rate should be $148. It says that is based on the mid-point between the base charge out rate of the defective FTM1000 ($140) and the actual rate charged out for the Bombardier work (said to be $156), the latter being (it says) the best sample of actual work done by the FTM1000.
23 FAT HACO submitted that the rate should be at least $180 an hour, if not $200 an hour, based on evidence from Mr Klappers and Mr Hollamby generally as to charge out rates and from the average rate of the four successful jobs contained in the 36 estimate sheets provided by Mr Hollamby of Ezy-Fit as representative examples of Ezy-Fit's work (discussed in Ezy-Fit No 1 at [1027]). It disputed Ezy-Fit's contention that the Bombardier work is the best sample to assess the overall rate, and in any event it disputed Ezy-Fit's alleged rate of $156 for the Bombardier work.
24 As a preliminary matter, I reject the submission made by Ezy-Fit that because I found there was a 30% probability that Ezy-Fit would have won high-end work on a fully functioning FTM1000 at a charge out rate of $220 an hour, I should generally find that an achievable actual charge out rate of the FTM1000 is low. I accept FAT HACO's submission that the 30% probability was based on Ezy-Fit's ability to win high-end work, which I found was priced at $220 an hour. The Sellars discount is not relevant to this assessment of the hourly charge out rate.
25 I consider there are relevantly three considerations that arise in fixing an hourly charge out rate for the purpose of this assessment.
26 First, I accept the premise that the rate should be determined having regard to the best evidence of actual rates Ezy-Fit charged out for the FTM1000. To that extent, the rate Ezy-Fit charged for the Bombardier work, which according to Ezy-Fit is $156 an hour, is relevant. However, it does not follow that evidence that shows Ezy-Fit at times charged out the FTM1000 at higher rates is to be ignored. As FAT HACO indicated, the four jobs from those in the 36 estimate sheets that Ezy-Fit actually won indicated the FTM1000 was charged out at least once at $165 an hour, once at $200 an hour and twice at $250 an hour. I accept that those jobs combined comprised only 164 hours of work, while the Bombardier work comprised potentially 1,270 hours. However, the fact those works were relatively smaller does not warrant excluding that evidence from consideration. There may be a number of reasons an hourly rate is lower for a larger job. I do not need to speculate further about that. And, as indicated by counsel for FAT HACO, the Bombardier work itself still only accounts for less than 15% of the total work the FTM1000 supposedly completed prior to judgment being reserved.
27 Further, the 36 estimate sheets show that Ezy-Fit was willing to provide quotes to potential clients charging out the FTM1000 at rates including $165, $200 and $220 an hour (for example, quote M0690 ($200), M0714-1 ($165), M0738 ($200), M0765-1 ($165) and M0782-1 ($220)). Even though Ezy-Fit did not win that work, those quotes still provide some indication as to the rates Ezy-Fit, which was best placed to price the FTM1000, considered it could achieve.
28 Second, I am not satisfied that Ezy-Fit has established that an accurate charge out rate for the Bombardier work is $156 an hour. Ezy-Fit determined that figure by using data from 'Shop Mate', production management software Ezy-Fit uses to record and measure productivity. According to Ezy-Fit, Shop Mate recorded a total of 1,270 labour hours against the relevant Bombardier job number, and Ezy-Fit's accounting expert Mr Morris was provided with relevant records from Ezy-Fit's debtors ledger that showed an income of $198,100 for the corresponding job. The rate has apparently been derived by dividing the income by the hours, yielding a rate of $156 an hour.
29 However, I accept FAT HACO's submission that the Shop Mate data only evidences the hours spent by particular employees on jobs on any particular day and has no meaningful connection to the actual charge out rate for the FTM1000. I also have reservations about relying on Shop Mate data in circumstances where it has not been fully explained by Ezy-Fit, and the accounting experts of both parties expressed caution in relying on it (Court Book at 3968-69; second report of Brian Morris at [6.59]). In my view, Ezy-Fit has not established any reliable connection between the hours recorded in Shop Mate against the Bombardier job and the figure of $198,100.
30 Nor am I satisfied that there is evidence showing the basis upon which Bombardier was actually charged, such as a contract or invoice, which might otherwise reveal an hourly charge out rate. Bombardier could have been charged a flat fee, either in total or per wheel set. Ezy-Fit may not have billed all the hours reflected in Shop Mate to Bombardier. There is simply too much guessing and speculation involved to accept that the charge out rate for the FTM1000 when utilised for the Bombardier work was $156 an hour.
31 Even if I accepted the use of the Shop Mate data, it appears that the proposed figure of $156 an hour effectively represents income earned per hour spent on the FTM1000. That is not necessarily the same as a 'charge out rate', at least as that term has been understood otherwise in the context of these proceedings. For example, according to Ezy-Fit's instructions to Mr Morris and reflected in the 36 estimate sheets, 'charge out rate' refers to the rate associated with a particular machine, billed alongside other hourly rates associated with a job, such as design work and project management (first report of Brian Morris at [5.36]). Importantly, that is the understanding of charge out rate that Mr Hollamby applied to his suggested rate of $220 an hour rate for the alternative machine (explained in his affidavit at [21]-[27]), which I adopted: Ezy-Fit No 1 at [1059]-[1061]. Therefore, for the purpose of fair comparison, that same understanding of charge out rate should be applied to the actual FTM1000 scenario.
32 I also observe that for the purposes of Ezy-Fit's wasted expenditure proposal (ultimately not pursued by Ezy-Fit - see [1102] of Ezy-Fit No 1), Ezy-Fit instructed Mr Morris to estimate the average income received per hour spent on the particular Bombardier job addressed above, and he estimated the figure to be $198 an hour. Mr Morris was given different instructions on the labour hours spent on the job, which he noted were inconsistent with the Shop Mate data he was also provided. Mr Morris elected to rely on his instructions rather than the Shop Mate data, noting that Mr Nguyen also identified 'issues' with the data generally (second report of Brian Morris at [6.56]-[6.59]). All of this simply points to doubts about the veracity of the figure of $156 for the Bombardier job as propounded by Ezy-Fit.
33 Third, I reject Ezy-Fit's submission that $140 is the base charge out rate for the FTM1000. The evidence of Mr Hollamby was at times difficult to follow. However, he deposed that he would not as a general rule price the FTM1000 below $165 an hour. That is consistent with the estimate sheets, which record the FTM1000 being priced once at $135 an hour, an exception to the general approach, and 16 times at or above $165 an hour. I am cognisant that the estimate sheets represent quoted work rather than work that was actually undertaken on the FTM1000, but in the absence of other evidence I am left to take that evidence into account and weigh it accordingly. I also note that under cross-examination Mr Hollamby agreed the rates the FTM1000 was achieving were 'more in the range' of $140 to $180 an hour, or 'perhaps' $200 an hour.
34 It follows that I am left with some actual evidence as to charge out rates for a small number of jobs, and evidence as to charge out rates generally. This evidence is limited, and I note that although the role of the Court in the assessment of damages is to do the best it can, it was Ezy-Fit that bore the responsibility and was in a position to adduce better evidence during the trial as to charge out rates. Overall, having carefully considered the evidence and submissions on this point, I conclude that $180 an hour is an appropriate charge out rate to be applied to calculate the profits accrued by use of the FTM1000.
