Loans and Non-performing Assets

Total loans at March 31, 2015 were $597.731 million, an increase of $111.869 million, $70.0 million from the PFC acquisition noted above, and down slightly from year end balances of $600.935 million.  Our organic balance sheet loan growth in the past twelve months was approximately $42 million, or 8.7%.  New loan production was solid in the 2015 first quarter at $31.4 million, although some larger loan payoffs and normal loan principal amortization resulted in a slight decrease in outstanding loan balances. Commenting on new loan production and overall lending activities, Kelly W. George, President and CEO of mBank stated, “We were generally pleased with our overall loan production for the quarter with almost $15 million in new commercial originations and over $16 million in consumer, primarily mortgage, where we have seen a nice uptick in the secondary market.  We expect that trend to continue as we move into our more seasonal lending origination months. The slight decrease in loan balances from various commercial loan pay downs for existing clients reflects borrowers’ actions to reduce debt with excess cash reserves, and a few commercial real estate relationships exiting the bank where available terms and rates were outside of our acceptable parameters. Our current loan pipeline remains good for both traditional commercial and SBA loans as we also move to a more offensive position within our newly acquired PFC markets after the successful operational and cultural merger of the company over the first quarter into the mBank operating environment.”

Nonperforming loans totaled $11.850 million, 1.98% of total loans at March 31, 2015 compared to $1.491 million, or .31% of total loans at March 31, 2014 and up from the $3.939 million from December 31, 2014.  Total loan delinquencies greater than 30 days resided at a nominal .95% or $5.612 million. Mr. George, commenting on credit quality, stated, “Our credit quality risk metrics and overall loan portfolio payment performance remains strong with no systemic issues within any segments of the portfolio. The increase in nonperforming assets in the 2015 first quarter totaling $7.911 million is due almost entirely to one large credit, an approximate $7.5 million local loan relationship, which the bank entered into in 2011 as a chapter 11 bankruptcy reorganization.  This relationship was established in conjunction with several other state and federal government lending parties who provided various loan guarantees, in order to preserve a long standing paper mill in our headquarters market and save over 150 jobs. The private equity owners of the mill shut the facility unexpectedly in late March of this year given ongoing projected capital needs they were unwilling to fund. We are proceeding with a cautiously optimistic posture that a new owner can be procured in the near-term as the mill has been open since 1914. We have taken prudent steps working with all lending parties to gradually wind down the mill and protect and control the disposition of our collateral should the mill fail to reopen.  We have been very pleased with the resolution of several of the acquired PFC problem assets, and expect further positive progress there as we work through their remaining nonperforming assets the first half of this year.  We believe our purchase accounting marks for the loans acquired are appropriate.”

Margin Analysis

Net interest income in the first quarter of 2014 increased to $7.520 million, 4.53%, compared to $5.593 million, or 4.25%, in the first quarter of 2014.  The increase in net interest income was largely due to the PFC acquisition as we increased earning assets by approximately $90 million.  We also had increased net interest contribution due to the accretive attributes associated with the purchase accounting adjustments related to PFC loan marks under GAAP. Mr. George stated, “We have been successful in maintaining our strong net interest margin within this historically low interest rate cycle though the use of continued targeted funding strategies and disciplined loan pricing in efforts to mitigate longer term interest rate risk where we maintain a favorable balance sheet position in a rising interest rate environment. We continue to look for any investment opportunities that fit our balance sheet structure but will not take unnecessary risk or extend duration in order to enhance short term yields. We will remain committed to our core banking philosophy which emphasizes loan growth as the best asset to invest in to benefit and help grow the economic bases in our local communities, which in turn also provides the best overall returns to our shareholders.”

Deposits

Total deposits of $597.913 million at March 31, 2015 increased by $122.203 million, ($100 million from the PFC acquisition noted above), from deposits of $475.710 million on March 31, 2014 and were down slightly from year end deposits of $606.973 million.  Mr. George, commenting on core deposits and overall liquidity needs, stated, “The Corporation maintains a strong liquidity position to fund operations and loan growth. We proactively review our short and long term funding needs and review our pricing levels within the different segments of our deposit products in order to best manage our net interest margin to capture as many dollars as we can. We will also utilize alternative funding sources such as internet CDs and small levels of wholesale deposits when deemed necessary to structure different liabilities to match asset growth durations, and

cover any potential short term funding gaps that could arise to protect our balance sheet in various interest rate change stress tests.”

Noninterest Income/Expense

Noninterest income, at $.624 million in the first quarter of 2015, decreased $.067 million from the first quarter 2014 level of $.691 million.  The primary reason for the decrease was a reduced level of gains on the sale of SBA/USDA loan balances which totaled $.118 million in the 2015 first quarter down from $.382 million in the first quarter of 2014.  Secondary market fees increased to $.167 million in the first quarter of 2015 compared to $.103 million in the first quarter of 2014. Noninterest expense, at $5.756 million in the first quarter of 2015, increased $.649 million, or 12.71% from the first quarter of 2014. The increase from the first quarter of 2014 was largely attributable to the PFC acquisition in December 2014 in terms of salaries and benefits, and some data processing costs which are expected to diminish now that the conversion is complete.

Assets and Capital

Total assets of the Corporation at March 31, 2015 were $728.844 million, up $145.252 million from the $583.592 million reported at March 31, 2014 and down $14.941 million from the $743.785 million of total assets at year-end 2014. The decrease in assets during the first quarter was primarily due to the reduction in deposits as we paid down some of our brokered deposits in connection with reductions in loan funding needs. Common shareholders’ equity at March 31, 2015 totaled $75.038 million, or $11.99 per share, compared to $65.730 million, or $11.89 per share on March 31, 2014.  The Corporation and the Bank are both “well-capitalized” with Tier 1 Capital at the Corporation of 8.75% and 9.41% at the Bank.

Paul D. Tobias, Chairman and Chief Executive Officer of Mackinac concluded, “With the recent acquisition of PFC, the combination of our organizations has resulted in significant accretive earnings in our first quarter of combined results and we expect this contribution to continue in future periods.  The expansion of our footprint from this business combination provided us with increased growth opportunities in the western U.P. markets and our increased asset size resulted in the anticipated operational efficiencies, which contributed to earnings accretion as anticipated. We believe that we will have additional accretive opportunities in the near term as the regulatory and operating costs for smaller banks dictate a larger asset base. We remain committed to our shareholders in all of our endeavors to increase value by building a safe and sound company with strong asset growth, increasing core earnings and growing returns on equity.”
