In order to implement the above-mentioned construction contract to the fullest, Lusail Company leased a machine from Qatar Leasing Company on June 30, 2018. The lease agreement stipulates that Lusail Company will pay a semi-annual rent amount of $907,652 during the first payment of the rent amount for the lease term, which amounts to 3 years, on June 30 and December 31 of each year, note that the semi-annual maturity starts from June 30, 2018. The borrowing rate of Lusail Company is 10%, which is the same rate used by Qatar Leasing Company when calculating the rent amounts due to it. Depreciation is recorded on a straight-line basis at the end of December of each year. The fair value of the machine is $3 million

In addition to the above, on January 1, 2019, Lusail Company issued bonds worth $1,500,000 for a period of 5 years at an interest rate of 4%. The value of the interest is due on a semi-annual basis on June 30 and December 31 of each year. This is knowing that the market rate of similar bonds is 6%. Lusail Company realizes that according to generally accepted accounting principles in the United States of America, companies can move from the effective interest method to the fair value method of accounting for their obligations with a simplified justification for doing so. On December 31, 2020, the market interest rate increased to 8%, which prompted Lusail Company to switch to the fair value method of accounting for its bonds. On the same date, the company estimated the fair value of its bonds at $735,342.1. Although IFRS allows the use of fair value for accounting for obligations, there are many restrictions and requirements to apply this. Unfortunately, Lusail Company did not meet these requirements, which forced the company to follow the effective interest method when reporting its bonds in the financial statements instead of the fair value method.
