Schedule of Share Based Compensation Restricted Stock Units Performance Awards Weighting

Each executive will receive between 0% and 200% of his or her target performance-based award based on the Company’s performance against established company-wide performance metrics, which are:

Metric	2016 - 2017 Grant	2013 - 2015 Grants
Average return on net assets (1)	50%	50%
Cumulative net income	25%	N/A
Cumulative earnings per share (2)	N/A	30%
Relative total shareholder return (3)	25%	20%

(1) Average return on net assets is measured by tax-affected operating income divided by average net working capital plus average net property, plant and equipment for each calendar year during the respective performance period.

(2) Cumulative earnings per share is measured by net income attributable to Aptiv divided by the weighted average number of diluted shares outstanding for the respective three-year performance period.

(3) Relative total shareholder return is measured by comparing the average closing price per share of the Company’s ordinary shares for all available trading days in the fourth quarter of the end of the performance period to the average closing price per share of the Company’s ordinary shares for all available trading days in the fourth quarter of the year preceding the grant, including dividends, and assessed against a comparable measure of competitor and peer group companies.
