Shares of Maruti Suzuki India tumbled 8.74% at Rs 1117.35 on Thursday, 19 July 2012, after violence at the company's Manesar plant stalled production. The company in a statement issued after market hours on Thursday, 19 July 2012, stated that the company was deeply disturbed by the mob violence and arson at the Manesar plant on Wednesday evening. Several executives, managers and supervisors were brutally attacked and injured, and nearly 100 of them had to be hospitalised. The company said General Manager (HR) at Manesar plant Mr. Awanish Kumar Dev was burnt to death by the mob.

Maruti said the company is still assessing the total damage to property and facilities from the acts of arson. The company added that the office facilities have been burnt beyond repair, as have the main gate, security office and the fire safety section. Maruti said its Manesar plant remained shut on Thursday. The company said it will shortly announce a decision on the next steps with regard to resuming operations at the unit. After being terrorized, abused and attacked in a brutal manner by the mob, recovery for the injured employees will not be easy, Maruti said adding that the management will ensure the injured employees continue to receive quality medical attention and that the company is extending all possible to the families of the injured employees.

Maruti suffered losses last year when workers had gone on an indefinite strike to form an independent union at the same plant.

Maruti's board of directors last month approved a proposal to merge Suzuki Powertrain India (SPIL) with the company. SPIL, which supplies diesel engines as well as transmissions for vehicles to MSIL, is a subsidiary of MSIL's parent -- Suzuki Motor Corporation (SMC), Japan. SMC holds a 70% share in SPIL and the remaining 30% is held by MSIL.

As per the terms of the proposed merger, SMC will receive one share of MSIL of Rs 5 each for every 70 shares of Rs 10 each it holds in SPIL. There will be no cash outflow from MSIL due to the merger. MSIL proposes to make a fresh issue of about 1.31 crore equity shares to SMC in lieu of SMC's 70% holding in SPIL. Consequent to the merger, SMC's holding in MSIL will go up from 54.2% to 56.2%.

It is expected that the necessary regulatory approvals and legal requirements for the merger may be completed by end December 2012, MSIL said. Once the merger is approved, the books of accounts of SPIL will be merged with MSIL with effect from 1 April 2012, the company added. The two companies, viz MSIL and SPIL, will work jointly to integrate the two organizations, MSIL said.

With the merger, MSIL will be able to bring its entire diesel engine capacity under a single management control. All key initiatives to strengthen the business, including sourcing, localization, production planning, manufacturing flexibility and cost reduction can be controlled, monitored and improved by the MSIL management, MSIL said in a statement. The proposed merger also promises benefits for the combined entity through synergies in areas like finance, capital structuring, and administration and consequent reduction of transaction costs, MSIL said.
