Positive momentum continues

Regions reported second quarter net income available to common shareholders of $259 million, or $0.18 per diluted share. During the second quarter the company executed several liability management activities that reduced diluted earnings per share by $0.03.

Regions’ performance for the quarter demonstrates that the company’s disciplined focus on identifying and meeting customer needs is resulting in sustainable growth across the franchise. Notably, total ending loan balances were up $1.1 billion linked quarter or 1.4 percent. Overall loan growth reflects slow but steady economic improvement in the company’s core markets as business and consumer deleveraging has slowed and demand for credit has begun to modestly increase. In addition, the company continues to grow organically by expanding the customer base through steady household growth and a disciplined focus on customer service.

“Regions’ positive momentum continued in the second quarter, as evidenced by broad-based loan and customer growth across our franchise with successful execution of key capital plan actions,” said Grayson Hall, chairman, president and CEO. “By continuing to execute on our business priorities, our company is well-positioned to capitalize on opportunities as the economy continues to improve.”

Capital plan actions reduce funding costs, increase return to shareholders

During the second quarter the company began executing various components of its capital plan. These actions improved the company’s financial performance by reducing funding costs, and at the same time, provided higher returns to shareholders through an increase in the dividend and the repurchase of common shares.

In addition to increasing the common dividend from $0.01 per diluted share to $0.03 per diluted share and beginning to execute on the approved share repurchases, this quarter’s capital plan accomplishments included:

Future net income will benefit from lower funding costs due to the redemption of higher cost liabilities that were replaced by lower cost debt. In addition, earnings per diluted share will benefit from the reduced share count. However, certain of these activities reduced second quarter pre-tax net income to common shareholders by $56 million and lowered earnings per diluted share by $0.03.

Loan balances increase

Total ending loan balances were $75 billion, an increase of $1.1 billion or 1.4 percent linked quarter. Loan growth was broad-based among product lines as well as across the company’s geographic footprint as approximately 70 percent of the company’s areas experienced loan growth. Total new loan production for the quarter was $8 billion, an increase of 23 percent linked quarter.

Total business lending, which is made up of commercial loans and investor real estate loans, increased 2.2 percent to $46 billion at quarter end. These loans make up 61 percent of the total loan portfolio. Much of this increase was driven by commercial and industrial loans, which experienced growth for the twelfth straight quarter. Ending loans in this category were up 5 percent compared to the prior quarter, and 11 percent over the same period last year. New loan production in this portfolio increased 36 percent linked quarter to $4 billion as the company experienced pick up in lending to small businesses as well as seasonal growth in demand overall. In addition, total commercial and industrial line commitments grew $2 billion, or 5 percent linked quarter.

The investor real estate portfolio declined during the second quarter; however, this portfolio experienced a more modest rate of decline compared to previous quarters. The pace of de-risking has slowed and has been somewhat offset by new production. Total new and renewed production in this portfolio increased 12 percent from the prior quarter and was driven by lending to well-qualified home builders and developers in select markets. At quarter end, the investor real estate portfolio totaled $7 billion and comprised 9 percent of the total loan portfolio, compared to 12 percent one year ago.

Consumer loans totaled $29 billion on an ending basis and remained flat linked quarter, indicating that consumer deleveraging has begun to subside. Consumer loan production totaled $3 billion in the second quarter, an increase of 12 percent over the prior quarter. Indirect auto loans experienced an increase in ending balances of 9 percent linked quarter. Production in the indirect auto portfolio totaled $508 million during the quarter, an increase of 21 percent linked quarter and 40 percent over the prior year.

Declines in the residential mortgage and home equity portfolios offset the growth in the indirect auto, credit card and other consumer portfolios as consumers continue to pay down real estate debt. However, loan originations for new home purchases were up for the quarter, accounting for almost 53 percent of all mortgage applications, compared to 35 percent last quarter.

Improved funding mix continues to drive deposit costs lower

Average low-cost deposits increased slightly linked quarter, while higher cost time deposits declined 11 percent. This mix shift drove continued improvement in the company’s funding composition, as low-cost deposits as a percentage of total deposits rose to 88 percent, compared to 83 percent last year. This positive mix shift resulted in deposit costs declining to 15 basis points for the quarter, down 3 basis points from first quarter and down 17 basis points from last year. As a result, total funding costs declined to 40 basis points, down 20 basis points from the same period one year ago.

Net interest income increased and net interest margin expanded

Taxable-equivalent net interest income was $821 million, a $10 million or 1 percent increase linked quarter. This was driven by growth in loans, an additional day count, as well as the continued decline in deposit costs. The resulting net interest margin expanded 3 basis points linked quarter to 3.16 percent, primarily attributable to lower deposit costs and a reduction in cash holdings at the Federal Reserve.

Non-interest revenue impacted by lower mortgage revenue

Non-interest revenue totaled $497 million, down 1 percent linked quarter. Mortgage income for the quarter totaled $69 million, a decline of 4 percent linked quarter. Mortgage production for the quarter was approximately $1.9 billion, a 6 percent increase from the prior quarter. The increase in market rates impacted the pipeline as well as the mortgage servicing rights (MSR) hedge, resulting in the net decrease in mortgage income. Service charges income was down 2 percent linked quarter, driven by lower non-sufficient fund (NSF) fees.

Expenses impacted by costs associated with capital plan actions

Non-interest expenses of $884 million increased 5 percent from the prior quarter, including $56 million in costs related to capital plan actions. Excluding these costs¹, non-interest expense declined 2 percent compared to the prior quarter. During the quarter, legal and professional fees as well as credit costs declined and were partially offset by increases in salaries and benefits. Total headcount increased this quarter by 226 positions primarily related to the addition of income-producing associates in the Regions Investment Services division that is part of the Wealth Management line of business.

Asset quality improvement continues

Asset quality continued to improve in the second quarter. The provision for loan losses totaled $31 million, or $113 million less than net charge-offs. Total net charge-offs were $144 million, a decline of 20 percent linked quarter and net charge-offs as a percentage of total average loans was 0.77 percent. The company’s loan loss allowance to non-performing loans coverage ratio was 1.09x and the allowance for loan losses as a percentage of loans was 2.18 percent as of June 30, 2013.

Non-performing assets totaled $1.7 billion and were down $93 million, or 5 percent linked quarter. Non-performing loans, excluding loans held for sale, improved $80 million, or 5 percent linked quarter. Inflows of non-performing loans were $328 million and total delinquencies were down 7 percent. Commercial and investor real estate criticized loans declined 4 percent in the quarter and were down 28 percent year-over-year.

Strong capital and solid liquidity

As previously mentioned, during the second quarter the company executed a number of transactions that continue to enhance the cost and efficiency of the company’s debt and capital structure. Tier 1 and Tier 1 common¹ capital ratios remained strong, ending the second quarter at an estimated 11.7 percent and 11.2 percent, respectively. The company’s liquidity position at both the bank and the holding company remains solid. As of June 30, 2013, the company’s loan-to-deposit ratio was 81 percent compared to 79 percent in the first quarter.

Use of non-GAAP financial measures

Regions believes that the presentation of pre-tax, pre-provision income (PPI) and the exclusion of certain items from PPI provides a meaningful base for period-to-period comparisons, which management believes will assist investors in analyzing the operating results of the company and predicting future performance. These non-GAAP financial measures are also used by management to assess the performance of Regions’ business. It is possible that the activities related to the adjustments may recur; however, management does not consider the activities related to the adjustments to be indications of ongoing operations. Regions believes that presentation of these non-GAAP financial measures will permit investors to assess the performance of the company on the same basis as applied by management.

Tangible common stockholders’ equity ratios have become a focus of some investors and management believes they may assist investors in analyzing the capital position of the company absent the effects of intangible assets and preferred stock. Traditionally, the Federal Reserve and other banking regulatory bodies have assessed a bank’s capital adequacy based on Tier 1 capital, the calculation of which is codified in federal banking regulations. In connection with the company’s Comprehensive Capital Analysis and Review process, these regulators supplement their assessment of the capital adequacy of a bank based on a variation of Tier 1 capital, known as Tier 1 common equity. While not prescribed in amount by federal banking regulations, under Basel I, analysts and banking regulators have assessed Regions’ capital adequacy using the tangible common stockholders’ equity and/or the Tier 1 common equity measure. Because tangible common stockholders’ equity and Tier 1 common equity are not formally defined by GAAP or prescribed in amount by the federal banking regulations, under Basel I, these measures are currently considered to be non-GAAP financial measures and other entities may calculate them differently than Regions’ disclosed calculations. Since analysts and banking regulators may assess Regions’ capital adequacy using tangible common stockholders’ equity and Tier 1 common equity, management believes that it is useful to provide investors the ability to assess Regions’ capital adequacy on these same bases.

Tier 1 common equity is often expressed as a percentage of risk-weighted assets. Under the risk-based capital framework, a company’s balance sheet assets and credit equivalent amounts of off-balance sheet items are assigned to one of four broad risk categories. The aggregated dollar amount in each category is then multiplied by the risk-weighted category. The resulting weighted values from each of the four categories are added together, and this sum is the risk-weighted assets total that, as adjusted, comprises the denominator of certain risk-based capital ratios. Tier 1 capital is then divided by this denominator (risk-weighted assets) to determine the Tier 1 capital ratio. Adjustments are made to Tier 1 capital to arrive at Tier 1 common equity. Tier 1 common equity is also divided by the risk-weighted assets to determine the Tier 1 common equity ratio. The amounts disclosed as risk-weighted assets are calculated consistent with banking regulatory requirements.

Non-GAAP financial measures have inherent limitations, are not required to be uniformly applied and are not audited. To mitigate these limitations, Regions has policies in place to identify and address expenses that qualify for non-GAAP presentation, including authorization and system controls to ensure accurate period to period comparisons. Although these non-GAAP financial measures are frequently used by stakeholders in the evaluation of a company, they have limitations as analytical tools, and should not be considered in isolation, or as a substitute for analyses of results as reported under GAAP. In particular, a measure of earnings that excludes selected items do not represent the amount that effectively accrues directly to stockholders.
