a) Data:
1. December 31, 2016 Write-off of Receivable (Hendricks Inc.) = $820,000
2. Changes in depreciation policies:
a) Office Furniture and Fixtures 10-year to 8-year useful life: Effect on Retained Earnings at December 31, 2016 = $250,000 less. Effect on 2017 Income = $60,000 less.
b) Equipment: sum-of-the-years' digits depreciation method: Effect on 2017 income = $110,000 more.
3. Ending inventory for 2016 overstated by $235,000 Prior period adjustment.
4. Preproduction costs for furniture division: New accounting method. Effect on 2016 Retained earnings = $375,000 less.
5. Inventories for Nursery division, from FIFO to LIFO to match current costs with revenues. Effect on 2017, an increase in Earnings = $320,000.

d) When Marthys Inc. change the inventory valuation method from LIFO to FIFO, it made a change in an accounting principle. Such principle changes are done retroactively, with the restatement of the financial statements.
