Company Background and Organization	1. Company Background and Organization Overview Motorcar Parts of America, Inc. and its subsidiaries (the "Company", "Consolidated Companies" or "MPA") is a leading manufacturer, remanufacturer, and distributor of aftermarket automobile parts. These replacement parts are sold for use on vehicles after initial vehicle purchase. These automotive parts are sold to automotive retail chain stores and warehouse distributors throughout North America and to major automobile manufacturers. The Company obtains used automobile parts, commonly known as Used Cores, primarily from its customers under the Company's core exchange program. It also purchases Used Cores from vendors (core brokers). The customers grant credit to the consumer when the used part is returned to them, and the Company in turn provides a credit to the customers upon return to the Company.

Fenco has a working capital deficiency and an accumulated deficit of approximately $99,818,000 and $198,074,000 at March 31, 2013, respectively. In addition, under the Fenco Credit Agreement, the Company has an outstanding term loan and revolving debt of $10,000,000 and $49,277,000 at March 31, 2013, respectively.
