Governmental accounting : Please explain how you arrived at the answer.

For the fiscal year ended 6/30/2016, what amount should be recognized as property tax revenues related to the 2016 levy on the governmental fund financial statements?

A city levies property taxes of $4 billion in June 2015 for its fiscal year beginning July 1, 2015. The taxes are due by January 31, 2016. The following (in millions) indicates actual and anticipated cash collections relating to the levy:

June 2015	$ 100
July 2015 through June 2016	$3,600
July 2016 through August 2016	$ 80
September 2016 through June 2017	$ 150

The city estimates that $30 million will eventually have to be refunded, owing to taxpayer appeals of the assessed valuation of their property, and that $70 million will be uncollectible.
