Final answer:
The adjustment to Pesto's beginning Retained Earnings as a result of this bond acquisition for a 2018 consolidation is a $340,000 increase.
Step-by-step explanation:
The adjustment that should be made to Pesto's beginning Retained Earnings as a result of this bond acquisition for a 2018 consolidation is an increase of $340,000.
Under the initial value method, Pesto would record the acquisition of the bonds at the original premium amount of $600,000. However, since Salerno acquired 40 percent of the bonds in 2017, the amortization of the premium should be adjusted based on the remaining 60 percent.
The amortization expense for 2018 would be $600,000 * 0.6 = $360,000. Since the original premium amount recorded was $600,000 and $360,000 has been amortized in 2018, the adjustment to Retained Earnings would be $360,000 - $20,000 (9% * $10 million * 0.6) = $340,000 increase.
