4. Business strategies of the Integrated Group

Immediate business strategies after the Business Integration will be as follows:

(1) Integrated Group

The Integrated Group will realize the integration synergy to the maximum extent at an early date, and will also conduct thorough structural reforms with zero-base thinking for the near term in order to enhance its competitiveness as a whole.

The Integrated Group will focus on the improvement of its financial structure and proceed with control of investment, sale of unnecessary assets, and thorough reduction of working capital in the aim of generating more cash flow and improving its balance sheet , whereby the Integrated Group will increase resilience against the risk and solidify the foundation for its future growth.

The Integrated Group will also focus on midstream and downstream businesses overseas, including the Asia-Pacific region, where further development is expected in the future. These initiatives will be an initial step toward the growth of the Integrated Group. At the same time, the Integrated Group will develop new businesses related to electricity and new energy as well as technology-based businesses, centered on high performance materials utilizing the existing technologies held by the Integrated Group, and this will achieve a balanced business portfolio including upstream, midstream and downstream businesses.

With respect to investment, the Integrated Group will level out investment timing, set priorities on investment projects, and strategically execute and select investment. By implementing these measures, the Integrated Group will place more emphasis on risk management and establish a management system capable of implementing capital efficiency-oriented strategies for investments and business portfolios so the Integrated Group can appropriately respond to changes in the business environment surrounding it.

(2) Energy business

While maintaining safe operations and stable supply, the Integrated Group will streamline and rationalize its entire supply chain, and thoroughly transform its business structure, thereby achieving a more resilient business foundation.

The Integrated Group will realize and maximize integration synergies of the business integration through continuous business transformation of the petroleum refining and sales and chemical businesses, which will continue to be core businesses and “earnings powerhouses” of the Integrated Group in the future.

With stronger business bases, the Integrated Group will develop and enhance next generation businesses of the group, such as overseas businesses, electricity, gas, new energy, lubricants, and specialty chemicals that will be mainstays of the future.

(3) Oil and natural gas exploration and production business

The Integrated Group will optimize its portfolio through concentration in core competence. New investments in the oil and natural gas E&P business are made in principle within the range of cash flow generated from such business.

( 9 / 16)

With respect to oil and gas fields under development and production, the Integrated Group will focus on cost reduction and steadily implement those oil and gas projects, with full attention to safety and the environment.

The Integrated Group will focus on the acquisition of technologies in the areas where it can exert the knowledge and strength it has accumulated to date, including CO2-EOR* technology and development technology for deep-water oil and gas fields.

“CO2-EOR technology” is a technology whereby carbon dioxide released from electric power plants is injected into a deep underground oil reservoir to enhance oil recovery, as well as carbon dioxide is deposited in the ground to mitigate its emissions into the atmosphere.

(4) Metals business

In its upstream business, the Integrated Group will refrain from investing in new upstream businesses for the time being, while focusing on the stable operation and cost reduction of the existing business, whereby it will dedicate all it strength to profit improvement.

In its copper smelting and refining business, the Integrated Group will establish safe and stable operation of refineries and make efforts to strengthen cost competitiveness by increasing efficiency thoroughly.

In its electronic materials business, the Integrated Group will distribute niche and high-performance products to global markets by utilizing competitive technology, and maintain and expand its earning capacity. In addition, the Integrated Group will make efforts to develop technology and markets for the coming “Internet of things” society.

In its recycling and environmental services business, the Integrated Group will strengthen its domestic and overseas collecting network and expand the business in order to contribute to the development of a recycling-oriented society.

7.	Integrated Holding Company’s policy for distributions to shareholders

Based on the recognition that the distributions to shareholders of the Integrated Holding Company is one of the most important management priorities, the Company which will become the Integrated Holding Company will continue to pay stable dividends, which will be determined with actual results and the outlook for mid-term consolidated performance. Furthermore, to determine the shareholder distribution level, the Integrated Holding Company will take into account the maintenance of its resilient financial structure, investment plan and cash flow outlook.

As a near-term policy for distributions to shareholders, the Integrated Holding Company will maintain the distribution level of 16 yen per share per year currently paid by the Company, and also will look for ways to increase the shareholder distribution by increasing its earning capacity. To this end, the Integrated Holding Company may consider buying back its own stock in addition to a dividend increase.

Expected dividends for the fiscal year 2017 will be announced along with the long-term vision and mid-term management plan of the Integrated Group.
