UPDATE 1-Lear Corp details post-bankruptcy balance sheet

* Lear provides post-restructuring capital structure

* No timetable for bankruptcy filing

* Lear sees 2009 revenue down a third from last year

DETROIT, July 6 (Reuters) - Auto seating supplier Lear Corp LEAR.PK said on Monday it planned to convert $3.6 billion in debt into a combination of new debt, convertible stock and equity warrants under a planned reorganization in bankruptcy.

Lear, which last week announced plans to file for Chapter 11 bankruptcy reorganization, did not provide a timetable for the move, saying it was seeking support for the proposed restructuring from more lenders and bondholders.

The company also forecast its revenue would drop by a third from last year to $9.07 billion in 2009, and recover to $11.38 billion in 2010. It had sales of $13.6 billion in 2008.

Lear said last week it had secured support for the proposed restructuring from key secured lenders and bondholders and had obtained $500 million in bankruptcy financing from a syndicate of secured lenders led by JPMorgan (JPM.N) and Citigroup (C.N).

"If the requisite support is obtained, Lear expects to commence shortly the proposed restructuring," the company said in a filing with the U.S. Securities & Exchanges Commission.

"However, no assurance can be given as to the level of additional support for the plan Lear ultimately will be able to obtain from its lenders and bondholders."

Under the planned debt restructuring, Lear targets to restructure $2.6 billion outstanding under its credit facility and $1.3 billion bond debt.

The company said its newly restructured balance sheet would consist of a $500 million first lien term loan, a $600 million second lien term loan, $500 million of convertible stock, and warrants to purchase 15 percent of Lear's new common stock.

The planned bankruptcy filing by Lear represents the largest in a string of recent failures of auto parts suppliers and highlighted the pressure on the sector from sharply curtailed production and bankruptcies at automakers General Motors Corp GMGMQ.PK and Chrysler.

Almost 80 percent of its sales last year were from auto seats supplied to customers such as GM and Ford Motor Co (F.N).

The Obama administration, which made $5 billion available to help auto suppliers obtain financing earlier this year, rejected a request by suppliers for up to $10 billion in additional financing last month.

Restructuring advisers and analysts have said the lack of new aid would result in a wave of bankruptcies because many suppliers lack capital to ramp up production now.

Chrysler began to restart production at its North American plants last week after a shutdown that began when it filed for bankruptcy protection on April 30.

A U.S. judge on Sunday approved GM's bankruptcy sale in a move that will allow the company's most profitable assets to exit bankruptcy protection under government ownership. (Reporting by Soyoung Kim; editing by Gunna Dickson)
