Hi tutor, if it's not too much to ask can you help me answer these problems related to IFRS 2 Share-Based Payments. Thank you!

1.On January 1, 2016, Dan Corporation granted an employee an option to purchase 3,000 shares of Dan's P5 par value ordinary share at P20 each. The option became exercisable on December 31, 2018. The option was exercised on January 10, 2019. The market prices of Dan's share capital were as follows: January 1, 2016 - P30; December 31, 2016 - P50; January 10, 2019 - P45. The company cannot reliably determine the fair value of the share option, so it decided to use the intrinsic value method. For the year 2016, how much should Dan recognize as compensation expense?

2.Melissa Corporation granted share options to its employees with a fair value of P4,500,000 on January 1, 2016. The options vest in three years and the options are exercisable starting January 1, 2019 until December 31, 2019. On December 31, 2016, it was estimated that 5% of employees will leave the entity during the vesting period. This estimate was revised to 6% during the year 2017. On December 31, 2018, employees' record indicates that 90% of the employees stayed and became entitled to the options. What would be the expense charged during the year ending December 31, 2016?
