Fixed asset problem

Dear Experts,

We have an asset capitalized on 2014/09/11 value 470,000 KRW, but user forgot to run AFAB (depreciation) in Dec, 2014. We don't know what happened to this asset, the initial value to 2015 is 0. We cannot find any value in asset balances, but we can see the value on balance sheet.

Do you have any good idea to handle this asset to make balance sheet and asset balances are equal?

Thank you,

Joanne Wu
