IFRS 15 Revenue Recognition

Dear Sir,

Thank you for such a nice explanation to the topic. I however have some clarity to seek on example 1 related to mobile handset and subscription revenue recognition. The period of obligation is 12 months. Suppose the customer takes the scheme on 1st of November. So effectively he has subscription of 2 months for current year and 10 months for next year. $50 per month effectively amounts to Rs 100 collected in year 1.

My question is and please correct my understanding (if it is incorrect) that since handset is already provided to customer, we records sale of handset of $ 214 on 1st November and make a receivables entry of simillar amount. As and when customer pays the $50 monthly, we apportion the amounts in ratio arrived of 35.7% towards handset receivable and 66% towards monthly service cost as income.

Is the above understanding correct??
