Deferred revenue consists mainly of receipts in respect of extended warranty to be realized in the coming five years. 

Accounting policy

The extended warranty fee received from  insurance companies (a fee per insurance contract sold) is taken to deferred revenue and released to profit or loss over the time of the committed warranty service period on a straight-line basis.
