Hello, can someone help me with the solution of this exercise step by step calculations and explanations? Thank you in advance!

One Orange juice future contract is on 15,000 pounds of frozen concentrate. Suppose that in September 2014 a company sells a March 2016 orange juice futures contract for 120 cents/pound. in Dec. 2014 the futures price is 140 cents, in Dec.2015 it is 110 cents, and in Feb.2016 it is closed out at 125 cents. The company has a December year end. What is the company's profit or loss on the contract? How is it realized? What is the accounting and tax treatment of the transaction if the company is classified as (a) hedger and (b) speculator?
