This would be true if the latest Pending Inventory is correct. If you consider August 2017 PI then the numbers would be 675+645+340 = 1660, so even if there are 1K SO it will suffice till March 15th 2009.
I personally feel that latest PI is wrong coz in 2008 alone there are 6,658 and if this num was correct dates would have been in 2008 and not 2009.
