Shawinegan Development Co. (SDC) conducts research and development on specific projects under contract for clients; SDC also conducts basic research and attempts to market any new products or technologies it develops. In January 20X4. scientists at SDC began research to develop a new industrial cleaner. During 20X4. $3.160.000 of costs were incurred in this effort. Late in July 20X5, potentially promising results emerged in the form of a substance the company called Scourge. Costs incurred through the end of July 20X5 were $1.540,000. At this point, SDC attempted to sell the formula and rights to Scourge to Pride and Glory Industries Lid. (PGIL). for $16,000,000. PGIL, however, was reluctant to sign before further testing was done. It did wish to have the first option to acquire the rights and formulas to Scourge if future testing showed the product to be profitable. SDC was very confident that Scourge would pass further testing with flying colours. Accordingly, the two companies signed an option agreement that allowed PGIL to acquire the formulas and rights to Scourge any time before 31 December 20X6. Testing costs on the product incurred by SDC for the remainder of 20X5 amounted to $1,800,000. On 6 March 20X6. PGILG exercised its option and agreed to purchase the formulas and rights to Scourge for $ 16,000,000. The formula was to be completed and delivered within 18 months. On 2 January 20X7, SDC delivered the formulas and samples of Scourge to PGIL. On that date, PGIL paid $6,400,000 immediately with the balance payable in four equal annual instalments on 31 December 20X7 to 20X10. Additional testing costs incurred by SDC during 20X6 amounted to $540,000, in 20X7, $260,000
