Marelli Holdings Co., the auto-parts supplier seeking to renegotiate its debt, selected current owner KKR & Co. as its sponsor in order to restructure the business.

As part of the turnaround plan, Marelli is seeking the cancellation of about 450 billion yen ($3.5 billion) in debt, out of obligations of about 1.13 trillion yen, according to people with knowledge of the matter.
