Hope these help:

Inventory Tunrover = Cost of Goods Sold / Avg. Inventory

As stated, the sales will be included in Year 3. In other words, the inventory has not been taken out as of Year 2.

For example:
Year 2
Cost of Goods Sold = $100,000
Avg Inventory = $200,000
Inventory Turnover = $100,000/$200,000 = 0.5

*If the item shipped (ex. $50,000 worth of goods) and included in Year 2 sales, the inventory turnover would be:

Cost of Goods Sold = $100,000+$50,000 = $150,000
Avg Inventory = $200,000-$25,000 = $175,000
Inventory Turnover = $150,000/$150,000 = 0.85
