Analyzing of Inventory and Footnote Disclosure

The inventory footnote from Deere & Company's 2013 10-K follows($ millions).

15. INVENTORIES

- A majority of inventory owned by Deere & Company and its US equipment subsidiaries are valued at cost,

on the "last-in, first-out" (LIFO) basis. Remaining inventories are generally valued at the lower of cost, on the "first-in, first-out" (FIFO) basis, or net realizable value. The value of gross inventories on the LIFO basis at October 28, 2018 and October 29, 2017 represented 54 percent and 61 percent, respectively, of worldwide gross inventories at FIFO value. If all inventories had been valued on a FIFO basis, estimated inventories by major classification at October 28, 2018 and October 29, 2017 in millions of dollars would have been as follows:

We note that not all of Deere's inventories are reported using the same inventory costing method

(companies can use different inventory costing methods for different inventory pools).

1. At what dollar amount are Deere's inventories reported on its 2018 balance sheet?

2. At what dollar amount would inventories have been reported on Deere's 2018 balance sheet had it used FIFO inventory costing?

3. What cumulative effect has the use of LIFO inventory costing had, as of year-end 2018, on its pretax income compared with the pretax income it would have reported had it used FIFO inventory costing? Explain.

4. Assuming a 25% income tax rate, by what cumulative dollar amount has Deere's tax liability been affected by use of LIFO inventory costing as of year-end 2018? Has the use of LIFO inventory costing increased or decreased its cumulative tax liability?

5. What effect has the use of LIFO inventory costing had on Deere's pretax income and tax

   liability for 2018 (assume a 25% income tax rate)?

6. Deere's 2016 annual report has similar disclosures but also states: "The pretax favorable income effects from the liquidation of LIFO inventory during 2016 and 2015 were approximately $4 million and $22 million, respectively." Explain what happened in 2015 and 2016 with respect to Deere's inventory and why there were favorable income effects.
