Final answer:
Sosa Enterprises would report $10,000,000 as its investment in Orioles Co. on its year-end 2013 balance sheet.
Step-by-step explanation:
To determine the amount that Sosa Enterprises would report in its year-end 2013 balance sheet for its investment in Orioles Co., we need to consider the changes in the fair value of the investment and any dividends received. The investment was initially valued at $3,000,000 and had a fair value of $10,000,000 on January 1, 2013. However, since there was no mention of any subsequent changes in the fair value, we can assume that the value remained the same throughout the year. Therefore, Sosa Enterprises would report $10,000,000 as its investment in Orioles Co. on its year-end 2013 balance sheet.
