Larry Corp. purchased a capital asset for $184,000 in early 2013. Management estimated that the asset would have a 10-year life with an estimated residual value of $37,000 and would be depreciated on a straight-line basis with a full year’s depreciation in the year of purchase. In 2015, management decides to change the depreciation method to 10% declining balance. This is a change in policy because the change is motivated by a desire to conform to industry practice. The tax rate is 40%.

Required:

1. Calculate depreciation expense for 2013–2015, inclusive, using the old policy and then the new policy.

2. Calculate the effect of the change on opening 2015, 2014, and 2013 retained earnings, if any.

Supply and Demand: In early 2020 the COVID-19 pandemic swept across the nation and world. In response, many workers moved from in-person working to remote working.
Webcams in particular showed an increase in the amount sold, especially the most well-known and trusted brands.

Suppose after the next election, the US abandons the trade war and removes the tariffs. What effect should that have on the price of webcams?
