Cheyenne Company adopted a stock-option plan on November 30, 2016, that provided that 73,800 shares of $5 par value stock be designated as available for the granting of options to officers of the corporation at a price of $9 a share. The market price was $11 a share on November 30, 2017.

On January 2, 2017, options to purchase 29,900 shares were granted to president Tom Winter15,800 for services to be rendered in 2017 and 14,100 for services to be rendered in 2018. Also on that date, options to purchase 15,000 shares were granted to vice president Michelle Bennett7,500 for services to be rendered in 2017 and 7,500 for services to be rendered in 2018. The market price of the stock was $15 a share on January 2, 2017. The options were exercisable for a period of one year following the year in which the services were rendered. The fair value of the options on the grant date was $5 per option. In 2018, neither the president nor the vice president exercised their options because the market price of the stock was below the exercise price. The market price of the stock was $8 a share on December 31, 2018, when the options for 2017 services lapsed. On December 31, 2019, both president Winter and vice president Bennett exercised their options for 14,100 and 7,500 shares, respectively, when the market price was $17 a share. Prepare the necessary journal entries in 2016 when the stock-option plan was adopted, in 2017 when options were granted, in 2018 when options lapsed, and in 2019 when options were exercised.
