       Notes to Consolidated Financial Statements
       2. Significant Accounting Policies, Revenue Recognition, page 71

   1.                                                   We note within your
response to comment 2 that you recognize upfront payments to
                                                        customers without
contractual volume guarantees as a reduction of revenue at the time of
                                                        the commitment to make
the payment. Please tell us in further detail how you determined
                                                        such accounting
treatment was more appropriate than recognizing the reduction of
                                                        revenue as the related
goods are transferred to customers. In doing so, ensure you explain
                                                        the underlying economic
reasons for the payments, your history of recovering the
                                                        payments, including
your history of renewals and average customer lives, whether the
                                                        payments secure an
exclusivity agreement with customers or provide other contractual
                                                        assurances, whether the
payments are expected to recur with the same customer, and
                                                        whether the related
supply contracts have specified lives.

2.       We note your response to comment 7 indicates that net income
attributable to Aptiv and
         the related margin are the most directly comparable GAAP measures to
Adjusted
         Operating Income and Adjusted Operating Income margin. Please tell us
how you
         determined operating income and operating income margin were not the
most directly
         comparable GAAP measures.
