Despite an additional tax expense of $2.37 million due to the new tax reform law, the parent company of Rockland Trust did not miss a beat in the fourth quarter of 2017.

Independent Bank Corp. reported net income of $22.1 million, or $0.80 per diluted share, for the quarter, up more than $4.5 million from the fourth quarter of 2016. Net income for the year was $87.2 million, $3.19 per diluted share, up more than $10 million from 2016. The bank’s efficiency ratio for the year was 59.78 percent.

Christopher Oddleifson, CEO of Independent Bank Corp. and Rockland Trust, expressed continued interest in growing the bank through acquisition.

“We have historically done an acquisition every few years. … Should (a bank) raise their hand, we would love to talk to them,” he said on an earnings call. “I think most importantly, when we think about a combined entity, we want to be able to continue our track record of performance.”

Acquisitions have played a major role in Rockland Trust’s growth over the past decade. The company purchased Benjamin Franklin Bank and its nearly $1 billion in assets in 2009. Rockland’s parent company acquired Somerville-based Central Co-operative Bank, gaining nine branches to the north and west of Boston, in 2012.

Following another acquisition of Mayflower Co-operative Bank in 2013, the company announced a year later it would purchase the holding company of People’s Federal Savings Bank, at last giving Rockland branches in the coveted Boston area.

Then Oddleifson turned his eyes toward the Cape, purchasing Bank of Cape Cod in 2016 and The Edgartown National Bank in Martha’s Vineyard in 2017. Oddleifson said on the earnings call that the bank had been able to retain 97 percent of customers at The Edgartown National Bank.

Total assets at the nearly $8.1 billion bank grew $370 million year-over-year. Net interest income for the year was $67.8 million, up more than $12 million from 2016. The net interest margin ended the year at 3.64 percent, up 28 basis points year-over-year.

Total loans reached $6.36 billion, up about $360 million year-over-year, driven primarily by growth in commercial, consumer real estate and home equity loans.

The company’s allowance for loan losses held steady at $60.64 million for the year, down slightly from a year ago. In the past year, nonperforming asset levels declined by 18.4 percent.
