Defective mobile phone brought in

Hello everyone,

I bought a mobile phone this year and, as I am self-employed in a secondary occupation, I contributed 50% of the cost with a depreciation over 3 years.

Now it has been dropped and cannot be repaired, the cost has been fully incurred and the mobile phone will not be used for 3 years. Can I book the full cost for this year and how do I do this in Dexxter?

Thanks in advance!

Regards,

Younes
