NORTHWEST INDIANA BANCORP

ANNOUNCES INCREASED EARNINGS FOR FIRST QUARTER

Munster, Indiana - NorthWest Indiana Bancorp (the “Bancorp”), the holding company for Peoples Bank, reported a first quarter earnings increase of 23.3%. Net income totaled $1.7 million for the three months ended March 31, 2013, compared to $1.4 million for the three months ended March 31, 2012.

The earnings of $1.7 million for the three months ended March 31, 2013, represent $0.59 earnings per basic and diluted share. For the first quarter of 2013, the return on average assets (ROA) was 0.97% and the return on equity (ROE) was 9.52%. At March 31, 2013, the Bancorp’s assets totaled $688.8 million.

"With net income up 23% over the first quarter of last year, the Bank is off to a solid start for 2013. Loan balances are up, asset quality is stable, and operating costs are down. We are pleased that the market has responded to our strong performance with a 20% increase in our share price since the beginning of the year," said David A. Bochnowski, Chairman and Chief Executive Officer.

Net Interest Income

Net interest income, the difference between interest income from loans and investments and interest expense paid to funds providers, totaled $5.8 million for the three months ended March 31, 2013, compared to $5.9 million for the three months ended March 31, 2012, a decrease of $53 thousand or 0.9%. The Bancorp’s net interest margin on a tax adjusted basis was 3.77% for the three months ended March 31, 2013, compared to 4.02% for the three months ended March 31, 2012. During the current quarter, the Bancorp’s net interest income and net interest margin continue to be positively impacted by the Federal Reserve’s sustained action in maintaining a low short-term interest rate environment, however, these measures are being negatively impacted by lower long-term interest rates.

Noninterest Income

Noninterest income from banking activities totaled $1.4 million, for the three months ended March 31, 2013, compared to $1.6 million for the three months ended March 31, 2012, a decrease of $234 thousand or 14.7%. During the three months ended March 31, 2013, the Bancorp’s noninterest income decreased primarily as a result of lower income from securities sales and loan related fees. During the first quarter of 2013, the Bancorp’s income from wealth management operations and loan sales increased compared to the same period for 2012.

Noninterest Expense

Noninterest expense related to operating activities totaled $4.8 million for the three months ended March 31, 2013, compared to $5.2 million for the three months ended March 31, 2012, a decrease of $427 thousand or 8.2%. During the three months ended March 31, 2013, the Bancorp’s noninterest expense decreased primarily as a result of lower occupancy, data processing and legal costs.

Funding

At March 31, 2013, core deposits totaled $397.1 million, an increase of $2.4 million or 0.6%, compared to December 31, 2012. Core deposits include checking, savings, and money market accounts and represented 70.6% of the Bancorp’s total deposits at March 31, 2013. The increase in core deposits is a result of customer preferences for liquid investments in the current low interest rate environment. During the first three months of 2013, certificate of deposit balances decreased by 3.8%, as management allowed higher cost deposits to mature while relying on lower cost core deposits. In addition, at March 31, 2013, borrowings and repurchase agreements totaled $51.0 million, an increase of $1.5 million or 2.9%, compared to December 31, 2012.

Lending

The Bancorp’s loan portfolio totaled $440.9 million at March 31, 2013, an increase of $3.9 million or 0.9%, compared to December 31, 2012. Loan growth for the first three months of 2013 was a result of increased loan origination activity. Residential mortgage loans and government loans increased by $6.7 million in the aggregate during the first quarter of 2013, while commercial and consumer related loans decreased by $2.8 million in the aggregate. During the three months ended March 31, 2013, $5.1 million of newly originated fixed rate mortgage loans were sold into the secondary market.

Investing

The Bancorp’s securities portfolio totaled $190.5 million at March 31, 2013, compared to $187.5 million at December 31, 2012, an increase of $3.0 million or 1.6%. The securities portfolio represents 29.2% of earning assets and provides a consistent source of earnings to the Bancorp. Cash & cash equivalents totaled $24.4 million at March 31, 2013, compared to $33.8 million at December 31, 2012, a decrease of $9.4 million or 27.8%. The decrease was primarily a result of funding loan and securities growth during the first quarter.

Asset Quality

At March 31, 2013, non-performing loans totaled $12.5 million, compared to $11.5 million at December 31, 2012 and $13.3 million at March 31, 2012. The current level of non-performing loans is concentrated with two geographically diverse commercial real estate participation loans that aggregate to $5.4 million. These participations were purchased from other originators during the period from 2005 through 2007, prior to the most recent recession. During April 2013, one of the two commercial real estate loans was sold to another investor. As a result, the balance on these participation loans of $5.4 million has since decreased to $4.6 million. The Bancorp’s ratio of non-performing assets to total assets was 2.02% at March 31, 2013, compared to 1.84% at December 31, 2012 and 2.44% at March 31, 2012. The increase in non-performing loans for the first three months of 2013 is primarily the result of commercial real estate and commercial business loans that were classified as impaired and internally classified as substandard at December 31, 2012.

For the three months ended March 31, 2013, loan loss provisions totaled $135 thousand, while $525 thousand in provisions were recorded for the three months ended March 31, 2012. The 2013 loan loss provisions were primarily related to the current credit risk for construction & development loans, and commercial real estate loans. Loan charge-offs, net of recoveries, totaled $209 thousand for the three months ended March 31, 2013, compared to $324 thousand for the three months ended March 31, 2012. At March 31, 2013, the allowance for loan losses totaled $8.3 million and is considered adequate by management. The allowance for loan losses as a percentage of total loans was 1.89% at March 31, 2013, compared to 1.93% at December 31, 2012. The allowance for loan losses as a percentage of non-performing loans, or coverage ratio, was 66.97% at March 31, 2013, compared to 73.34% at December 31, 2012.

Capital Adequacy

At March 31, 2013, shareholders’ equity stood at $68.1 million or 9.9% of total assets.
