Summary:

Content (required):

Hi,

the depreciation of the attached asset (cost 1000, depreciation method 20%) is equal to 1,30 for the first period in service (May-23). The placed in service date is 31/5/23 and the prorate date is 1/5/23 (monthly prorate). 

For this asset book the divide depreciation is set to evenly and the prorate calendar is daily.

Could you please check and let me know how that value is calculated?

Best,

Andrea
