Norio Sasaki, the new president of Toshiba Corp., said he aims to boost the company's capital adequacy ratio to 30 percent during his stint as he strives to return the struggling tech giant to profitability.

"My No. 1 biggest mission and responsibility is to ride out this crisis and achieve recovery of our businesses so that we can make a fresh start for profitability and sustainable growth," Sasaki, 60, said in a recent interview with media.

Formerly vice president, Sasaki officially took the helm of the electronics giant Wednesday. Toshiba fell deeply into the red for the first time in seven years in business 2008 to March and logged its biggest-ever group net loss of more than ¥340 billion.
