The TDK Group's consolidated sales in the fiscal year ended March 2011 reached ¥875.7 billion, up 8.3% over the previous year. The principal reasons included a global rise in demand in the communications sector, centered on smartphones, and a firm increase in demand in the automotive electronics sector.

Despite several negative factors, including exchange rate fluctuations, declines in retail prices, and the impact of the Great East Japan Earthquake, operating income in the fiscal year ended March 2011 reached ¥63.8 billion, a large increase of 148% over the previous year. This was the result of accurately responding to demand in the passive components business, primarily in major developed countries and emerging markets.

The operating income rose significantly, and as for non-operating income (deductions), though TDK suffered an exchange rate loss as a result of yen appreciation, there was no major change due to a decrease in interest expenses and a decrease in impairment loss on investment securities.
As a result, current-term net income in the fiscal year ended March 2011 reached ¥45.3 billion, a large increase of 235% over the previous year. Also, the return on equity (ROE) rose from 2.5% to 8.4%.
