Here is what the 2015 highlights said:
"The bargaining committee also removed the cap on the amount of company profits captured in our profit-sharing plan. In the 2011 agreement, we would not have been paid on any profits above $12 billion. That is no longer the case. The cap is eliminated, allowing UAW-Ford members to truly share in all of the upside when times are extremely good."
Therefore, your pay would still be based off of how many straight time hours you were paid. This is what one of my checks showed at the bottom of the stub, the calculation for what I was paid:
YOUR UAW-FORD PROFIT SHARE EQUALS COMPENSATED HRS
OF 2,745.50 TIMES THE 2017 $/COMP HR OF 3.39907
