Chairman Gamini Wickramasinghe said a target for one trillion in assets and ten billion rupees in profits was set for 2012 in 2009, but at the time many people thought it was not achievable.
"We were able to do it because of because the earlier management had put a good foundation," Wickramasinghe said.
"We have achieved this growth without compromising on asset quality or undermining risk management. Our non performing loans are about 2 percent."
Wickremasinghe said the bank was lending to all sector of the economy and also to customers in the former war torn areas in the North and the East.
The bank has a loyal customer base in the area as it was one of the few banks to operate in even separatist controlled areas during the island's 30-year war.
Wickremasinghe said the bank was looking to boost its capital.
"We hope the government will re-invest our dividends as equity," he said.
Chief financial officer Asoka Rupasinghe said though its capital was strong, to grow fast in the future it had to have strong equity buffer to be able to absorb shocks.
The bank is now rated and taps international capital markets.
By March 2012 the bank had 942 billion rupees in assets on a standalone basis up 12.7 percent from a year earlier while group assets were 962 billion rupees.
Last month it raised a 500 million US dollar bond. Officials say about 30 percent of its assets are dollar denominated.
It is also a large lender to the state and to state enterprises. About 30 percent of its loans are to state enterprises.
