Answer:
 -3.41%
Step-by-step explanation:
The computation of the annual rate of return is shown below;
We use the formula: 
Future value = Present value × (1 + rate of interest)^number of years 
 $10,710,500 = $12,738,500 × (1 + rate of interest)^5 
 ($10,710,500 ÷ $12,738,500)^(1 ÷ 5) = (1 + rate of interest) 
 (1 + rate of interest) = 0.965913622 
 r = (0.965913622 - 1) × 100
= -3.41%
