Forecasts therefore include risks and uncertainties. Actual figures may differ from these forecasts due to subsequent changes in the circumstances. 1. Qualitative Information on the Consolidated Financial Statements (1) Qualitative Information Regarding Consolidated Results of Operations The Japanese economy during the first three months of the fiscal year ending December 31, 2022 generally continued to be unpredictable with concerns about the global rebound of the novel coronavirus infectious disease (COVID-19), supply chain disruptions, shortages in the supply of semiconductors and other components, rising energy and raw material prices, as well as concerns about the impact on the economy from the escalating situation in Ukraine. In this economic environment, we have continually concentrated on acquiring new customers aggressively mainly through internet advertisements (paid listings) and internet search engine optimization (SEO), which can improve our website’s position on the search engines. We also conducted promotion activities including direct mail using e-mail and mail flyers, daily special prices, the publication and distribution of catalogs. In terms of catalogs, we newly published RED BOOK vol. 18 Spring Edition in late February, divided into 13 volumes with 174 thousand items and approximately 3.1 million issues available in total. Furthermore, the total number of our product lineup reached approximately 18 million items in total and 49.7 thousand items in stock which are available for the same day shipment to meet the increase in demand corresponding to the expansion of our customer base as of the end of the first three months of the fiscal year ending December 31, 2022. In addition, in relation to the sales of MRO products to large customers through the integrated purchase systems, both the number of customers and the amount of sales steadily increased. Consequently, we have successfully obtained 316,868 newly registered accounts for the first three months of the fiscal year ending December 31, 2022 and the number of registered accounts totaled 7,096,187 as of the end of the first three months of the fiscal year ending December 31, 2022. In addition, NAVIMRO, which is our Korean subsidiary, also aggressively engaged in acquiring new customers mainly through paid listings and focused on increasing both its product lineup and the number of products in stock in order to expand its customer base. All of our efforts mentioned above resulted in net sales of 54,610 million yen (18.7% increase from the same period of the previous fiscal year), operating income of 6,664 million yen (10.9% increase from the same period of the previous fiscal year), ordinary income of 6,746 million yen (10.9% increase from the same period of the previous fiscal year), and net income attributable to owners of the parent of 4,709 million yen, a corresponding 11.0% increase. (2) Qualitative Information Regarding Consolidated Financial Position Total assets as of March 31, 2022 (the end of the first three months of the fiscal year ending December 31, 2022) amounted to 102,081 million yen, an increase of 6,292 million yen from the end of the previous fiscal year. This was attributable to increases of 4,886 million yen, 2,435 million yen and 1,686 million yen in construction in progress, notes and accounts receivable-trade and software, respectively, despite decreases of 2,343 million yen and 1,609 million yen in cash and deposits and software in progress, respectively. On the other hand, total liabilities as of March 31, 2022 amounted to 39,874 million yen, an increase of 4,369 million yen from the end of the previous fiscal year. This was due mainly to increases of 3,238 million yen and 2,045 million yen in accounts payable-other and accounts payable-trade, respectively, despite a decrease of 1,934 million yen income taxes payable. Total net assets amounted to 62,206 million yen, an increase of 1,923 million yen from the end of the previous fiscal year. This was largely due to net income attributable to owners of the parent of 4,709 million yen offset by dividend payments of 2,856 million yen for the first three months of the fiscal year ending December 31, 2022. As a result, the equity ratio as of March 31, 2022 was 60.0%, down 1.9 percentage points from the end of the previous fiscal year. (3) Forecast for the Fiscal Year Ending December 31, 2022 Our consolidated financial results for the first three months of this fiscal year were almost in line with our plan. Therefore, the consolidated forecast for the fiscal year ending December 31, 2022, disclosed on February 3, 2022, has not been changed at this time. 2.
