Asset Quality

Delinquent loans continued to decline through the first quarter of 2013. As of March 31, 2013, delinquent loans were $46.7 million, down $1.5 million, or 3.2%, from December 31, 2012. Nonperforming loans also continued to decline. Nonperforming loans as of March 31, 2013 were down $3.1 million, or 6.4%, from $47.8 million at December 31, 2012. Nonperforming assets were $60.5 million as of March 31, 2013, down $5.7 million, or 8.7%, from $66.2 million at December 31, 2012.

The provision for loan losses increased to $2.1 million in the first quarter of 2013, compared to $680,000 in the first quarter of 2012. This $1.4 million increase in the provision for loan losses is primarily a result of chargeoffs of $560,000 associated with one commercial lending relationship and a $382,000 specific reserve established on another commercial relationship due to events surrounding these credits that occurred in the first quarter of 2013.

Net Interest Income and Margin

Net interest income for the three months ended March 31, 2013 and December 31, 2012, was $12.9 million and $14.0 million, respectively. Total interest income decreased $1.4 million in the first quarter of 2013 compared to the prior quarter, primarily because of a decrease of $36.7 million in the average balance of outstanding loans. United Community also experienced a decrease in the yield on net loans of 29 basis points.

Total interest expense decreased $267,000 for the quarter ended March 31, 2013, as compared to the prior quarter. The change was due primarily to reductions of $235,000 in interest paid on deposits. The overall decrease in interest expense was attributable to a shift in deposit balances from certificates of deposit to relatively less expensive non-time deposits. Between December 31, 2012, and March 31, 2013, the average outstanding balance of certificates of deposit declined by $30.2 million, while non-time deposits increased by $9.4 million. Also contributing to the decrease was a reduction of six basis points in the cost of certificates of deposit, as well as a decrease of three basis points in the cost of non-time deposits.

Noninterest Income

Noninterest income decreased in the first quarter of 2013 to $5.7 million, as compared to noninterest income for the prior quarter of $6.9 million. Decreased noninterest income was a result of lower service fees and other charges, lower gains recognized on the sale of securities available for sale and decreased mortgage banking income recognized in the first quarter of 2013 as compared to the previous quarter.

The overall change in service fees and other charges was a result of a higher valuation adjustment recognized on deferred mortgage servicing rights in the last quarter of 2012 as compared to the first quarter of 2013. A lower gain recognized on the sale of available for sale securities was the result of fewer sales during the current quarter as compared to the prior quarter. The decline in mortgage banking income is attributable to a lower volume of sales in the first quarter of 2013 as compared to the prior quarter, as Home Savings retained a more significant portion of 15-year mortgage originations in its loan portfolio rather than selling such loans in the secondary market.

Noninterest Expense

Noninterest expense was $13.9 million in the first quarter of 2013, compared to $14.3 million in the prior quarter. In the first quarter of 2013, deposit insurance premiums were lower due to the bank being able to avail itself of more favorable insurance rates and a lower average asset base used in the calculation of insurance premiums. Professional fees were $796,000 lower during the quarter ended March 31, 2013 as compared to the quarter ended December 31, 2012. The improvement in asset quality has reduced the need to engage legal and other consultants to assist in the resolution of problem assets. Other expenses were $635,000 higher in the first quarter of 2013 as compared to the last quarter in 2012. This variance is the result of higher expenses accrued in the first quarter for loans expected to be repurchased from Fannie Mae and Freddie Mac.

Capital and Book Value per Common Share

Home Savings’ Tier 1 leverage ratio was 9.84% as of March 31, 2013, as compared to 8.70% as of December 31, 2012. Home Savings’ total risk-based capital ratio was 18.28% at March 31, 2013, as compared to 16.21% at December 31, 2012. Tangible book value per common share at March 31, 2013 was $4.81, as compared to $5.16 at December 31, 2012.

The Consent Order issued by the FDIC and the Ohio Division of Financial Institutions in 2012 required Home Savings to maintain a Tier 1 Leverage Capital Ratio at a minimum of 9.0% and a total risk-based capital ratio of no less than 12.0%. The FDIC and the Ohio Division terminated the Consent Order on January 31, 2013. Home Savings is now considered well capitalized and is no longer considered a troubled institution. The Memorandum of Understanding (MOU) entered into on January 31, 2013, now requires Home Savings to maintain these ratios at 8.5% and 12.0%, respectively. As of March 31, 2013, Home Savings was in compliance with the MOU.

On January 11, 2013, United Community entered into securities purchase agreements with 28 accredited investors, pursuant to which the Investors agreed to invest an aggregate of approximately $39.9 million in United Community for 6,574,272 newly issued common shares of United Community at a purchase price of $2.75 per share, and 7,942 newly created and issued perpetual mandatorily convertible non-cumulative preferred shares of United Community at a purchase price of $2,750 per share. On March 22, 2013, UCFC received $39.9 million from the completion of this portion of the capital raise. On March 26, 2013, United Community invested $16.0 million from those proceeds into Home Savings.
