1. 1.Note 1 includes accounting information. What is the fiscal year for your SEC 10-K Company? This may be June 30 each year, or it may be the Sunday closest to the last day of January, or some other description.
3. 2. Inventory: How is Inventory described for your SEC 10-K company? LIFO, FIFO, and/or average cost? Relate your answer to topics in our course.
5. 3. Income Statement: Is it a single-step or multi-step income statement?
7. 4.Calculate the Gross Profit and Gross Profit Percentage for this year and last year, creating a small table, such as the following:

	This Year	Last Year
Net Sales	$1,200	$1,400
Cost of Goods Sold	800	1,200
Gross Profit	400	200
Gross Profit Percentage	33%	14%

Sales decreased, but sales are actually generating more profit overall, both as an absolute dollar value and as a percentage
