Hi,
The lapsing schedules are the files that contain the fixed asset informtion. They project the anticipated depreciation based on cost, depreciation method, salvage value( if applicable) and the useful life. The schedules show what depreciation is expected to be booked. I believe they are used in conjunction with capital expebditure budgets and cash flow budgets (the depreciation is a non cash expense that has an associated tax benefit).
regards,
