Asset transfer and depreciation calculation

Hi all, 

We purchased an asset on 1.1.2012 for $60000 with a useful life of 5 years. Depreciation is based on useful life of the asset. The monthly depreciation is $1000.

This asset has to transfer to intercompany A on 1.7.2012 with NBV $54000. Now, how should i calculate the depreciation on intercompany A's book?

Thanks & Regards,

Wee
