On January 4, 2015, a research project undertaken by Nasja Ltd. was completed and a patent was approved. The research phase of the project incurred costs of $150,000, and legal costs incurred to obtain the patent approval were $20,000. The patent is assessed to have a useful life to 2025, or for ten years. Early in 2016, Nasja successfully defended the patent against a competitor, incurring a legal cost of $22,000. This set a precedent for Nasja who was able to reassess the patents useful life to 2030. During 2017, Nasja was able to create a product design that was feasible for commercialization, but no more certainty was known at that time. Costs to get the product design to this stage were $250,000. Additional engineering and consulting fees of $50,000 were incurred to advance the design to the manufacturing stage. Nasja follows IFRS.

Required:

a. Prepare all the relevant journal entries for the project for 2015 to 2017, inclusive.

b. What is the accounting treatment for the engineering and consulting fees of $50,000?
