The parent company of Medford-based Century Bank had record earnings for the year of 2018.

The company reported net income of $36.2 million in 2018, or $6.50 per Class A share diluted, an increase of 62.4 percent compared to net income of $22.3 million, or $4.01 per Class A share diluted, in 2017.

Net income for the fourth quarter of 2018 was just over $9.2 million, up from $25,000 in the fourth quarter of 2017, a quarter in which many banks struggled because of a one-time write-down as a result of the new tax reform bill passed that quarter.

Net interest income for the year was $92.6 million, up from $85.6 million in 2017. The margin declined to 2.18 percent, down seven basis points year-over-year.

Total deposits were roughly $4.08 billion at the end of 2018, up about $208 million from the end of 2017. Despite deposit pressure, Century has managed to grow money market and saving account volume, even if not at the same pace as in other years.

Total loans at the end of year reached $2.29 billion, up about $110 million from one year prior. The bank grew its residential real estate portfolio the most, reaching roughly $348 million at the end of the year, up more than $60 million from one year ago.

Home equity loans also rose, while commercial and industrial, municipal and construction and land development loans also saw decreases year-over-year. Commercial real estate and consumer loans saw marginal increases.

While still a small proportion, nonperforming assets at the bank more than doubled from 2017, reaching past $3.5 million. The bank in its earnings report attributed this to one residential real estate property in the other real estate owned category.
