   1.                                                   We note from your 
response to prior comment 1. Considering the BN Performance Bonus
                                                        plan requires continued 
employment at the time of such payment, and as the amounts will
                                                        be paid in cash, it 
remains unclear how such charges are not a normal, recurring cash
                                                        operating expenses. 
Please revise to remove these adjustments from your non-GAAP
                                                        measures. Refer to 
Question 100.01 of the non-GAAP C&DIs.
