I already have some of this one figured out...but can't seem to get the rest:

On January 1, 2016, when its $30par value common stock was selling for $80per share, Coronado Corp. issued $10,200,000of 8% convertible debentures due in 20 years. The conversion option allowed the holder of each $1,000bond to convert the bond into five shares of the corporation's common stock. The debentures were issued for $11,016,000. The present value of the bond payments at the time of issuance was $8,670,000, and the corporation believes the difference between the present value and the amount paid is attributable to the conversion feature. On January 1, 2017, the corporation's $30par value common stock was split 2 for 1, and the conversion rate for the bonds was adjusted accordingly. On January 1, 2018, when the corporation's $15par value common stock was selling for $135per share, holders of 30% of the convertible debentures exercised their conversion options. The corporation uses the straight-line method for amortizing any bond discounts or premiums.
