The name of the Bill of materials has been changed in 2016 to the Cost Accounting Worksheet (CAW).
It is the same as in previous seasons, except this year teams do not have to report individual COTS items that are less than $5 USD each( or KOP items, but has been like this for a while).
The link is available on at the bottom of the linked thread
Good luck with the CAW, I found that doing the CAW is a good way to learn about all the different COTS parts available.
You can send me a PM if you are having trouble identifying any parts, but I'm sure you won't need to!
