From our understanding, the assets (floating crane etc) are property of PPYC Bangkok and they should be treated based on your accounting standards/practices - there is no reason to reflect those assets in the financial statements of PPYC Malaysia Sdn Bhd.
PPYC Malaysia Sdn Bhd is just using the assets, for which it pays charter fee. The charter fee should be treated as expense in the accounts of PPYC Malaysia Sdn Bhd and as income in the accounts of PPYC Bangkok.
For further information, kindly refer to my email to Capt. Lerdnarong on 12 February, which has been cc-ed to you.
