1. Matters Relating to the Preparation of the Quarterly Consolidated Financial Statements

(1)    Adoption of simplified accounting methods:	None
(2)    Accounting methods differing from those adopted for the latest fiscal year:	Yes

Depreciation and Amortization of Buildings

Buildings (excluding fixtures) purchased on and after April 1, 1998, had been depreciated using the declining-balance method, however, as of the period under review the Company depreciates such buildings using the straight-line method. This change resulted in a ¥160 million increase in operating income, ordinary income and net income before income taxes and minority interests for the period under review.

Impairment of Property, Plant and Equipment

As of the period under review, the Company adopted the new accounting standard for impairment of property, plant and equipment (“Opinion Concerning Establishment of Accounting Standard for Impairment of Fixed Assets” issued by the Business Accounting Deliberation Council on August 9, 2002) and the implementation guidance for the accounting standard for impairment of fixed assets (the Financial Accounting Standard Implementation Guidance No. 6 issued by the Accounting Standards Board of Japan on October 31, 2003). As a result of this adoption, net income before income taxes and minority interests decreased by ¥1,339 million.

(3) Changes in the scope of consolidation and application of the equity method: Yes

Consolidated subsidiaries:

Increase: 0

Decrease: 6

Companies accounted for by the equity method:

Overview of Results of Operations

On September 28, 2005, Daiichi Pharmaceutical Co., Ltd. and Sankyo Company Limited established DAIICHI SANKYO COMPANY, LIMITED, under which both companies became wholly owned subsidiaries, marking the start of operations as the DAIICHI SANKYO Group.

Regarding prescription drugs, sustained efforts to control healthcare costs in Japan continued to create harsh market conditions. Amid these conditions, the Daiichi Pharmaceutical Group further augmented its efforts to provide information related to drug efficacy and safety. As a result, consolidated net sales increased 4.7% from the level in the same period of fiscal 2004, to ¥172,815 million, supported by growth in sales of such mainstay products as Cravit^®, a broad-spectrum oral antibacterial agent; Artist^®, a long-acting beta-blocker; Zyrtec^®, a long-acting selective H1 receptor antagonist for the treatment of allergic diseases; Mobic^®, a non-steroidal anti-inflammatory agent; HANP^®, an agent for acute heart failure; and Topotecin, an anticancer drug. Overseas prescription drug sales rose 20.2%, to ¥51,194 million, reflecting the strong bulk exports of the antibacterial agent levofloxacin to North America and Europe as well as the yen’s depreciation against foreign currencies. Thus, consolidated net sales were up both in Japan and overseas.

In OTC drug operations and fine chemicals operations, the Daiichi Pharmaceutical Group faced harsh market conditions that depressed consolidated net sales.

As a result, in the first nine months of fiscal 2005, the Daiichi Group generated net sales of ¥266,593 million, reflecting a 5.0% increase from the same period of the previous fiscal year. The Group also made steady progress in terms of income. Operating income surged 26.2%, to ¥60,970 million, ordinary income rose 26.5%, to ¥62,793 million, and net income soared 37.8%, to ¥34,922 million, owing in part to cost reductions stemming from the establishment of Daiichi Pharmatech Co., Ltd., that helped to offset an increase in expenses attributable to the advancement of global R&D and business integration preparations.

As for results for the full fiscal year ending March 31, 2006, we expect to meet our projections as presented at the time of the interim results announcement. In addition, in the fourth quarter of fiscal 2005, we anticipate the recording of a business integration-related loss as well as a portion of lump-sum income for Plavix^®.

Overview of Financial Position

Total assets at the end of the period under review rose ¥28,363 million, to ¥574,918 million, compared with the end of the previous fiscal year. This increase is primarily attributable to a ¥19,771 million rise due to an increase in the market value of investment securities.

Shareholders’ equity grew ¥15,617 million, to ¥464,180 million, compared with the end of the previous fiscal year, owing to a ¥15,942 million increase in the valuation difference on other securities due to the reevaluation of investment securities, which offset a decrease in retained earnings attributable to the payment of dividends and the retirement of treasury stock.

Notes:

1. Method of classifying operating segments

Classifications into ‘Pharmaceuticals’ and ‘Other’ are based on a consideration of product type, market characteristics, and other factors.

2. Main products in each operating segment

Pharmaceuticals: Pharmaceutical products, diagnostic and radiopharmaceutical products, and over-the-counter drugs

Other: Fine chemicals, safety testing and research, real estate rental, and other

3. Changes in accounting policies

(First nine months of fiscal 2005)

Buildings (excluding fixtures) purchased on and after April 1, 1998, had been depreciated using the declining-balance method, however, as of the period under review the Company depreciates such buildings using the straight-line method. This change resulted in a ¥160 million increase in operating income due to a ¥152 million decline in operating expenses in the “Pharmaceuticals” business and a ¥7 million decline in operating expenses in the “Other” business.

[Geographic Segment]

Information by geographic segment has been omitted because more than 90% of total segment sales and segment assets were attributable to Japan.
