Income Statement

Net interest income was $201.6 million in the third quarter 2017, an increase of $8.8 million from $192.7 million in the second quarter 2017 and an increase of $29.0 million, or 16.8%, compared to the third quarter 2016. Net interest income in the third quarter 2017 includes $7.5 million of accretion income from acquired loans, compared to $7.1 million in the second quarter 2017, and $8.8 million in the third quarter 2016.

The Company’s net interest margin in the third quarter 2017 was 4.65%, an increase from 4.61% in the second quarter 2017, and from 4.55% in the third quarter 2016. The increase in net interest margin from the second quarter 2017 and the third quarter 2016 is attributable to higher yields on loans as a result of rising interest rates, as well as an increase in yields from investment securities.

Operating non-interest income was $9.9 million for the third quarter 2017, compared to $10.5 million for the second quarter 2017, and $10.7 million for the third quarter 2016.¹ The decrease in operating non-interest income from the prior quarter primarily relates to a decrease in income from equity investments. The decrease in operating non-interest income from the third quarter 2016 is due primarily to a decrease in lending related income, resulting from decreased SBA income.

Net operating revenue was $211.5 million for the third quarter 2017, an increase of $8.3 million, or 4.1%, compared to $203.2 million for the second quarter 2017, and an increase of $28.3 million, or 15.4%, compared to $183.2 million for the third quarter 2016.¹  

Operating non-interest expense was $88.8 million for the third quarter 2017, compared to $88.0 million for the second quarter 2017, and $82.4 million for the third quarter 2016.¹ Operating non-interest expense held relatively flat from the prior quarter as the decrease in legal, professional and directors' fees resulting from vesting of director restricted stock awards at the end of the second quarter 2017 was offset by increases in deposit costs and charitable contributions during the quarter. The increase in operating non-interest expense from the third quarter 2016 relates primarily to higher compensation costs resulting from an increase in the number of employees to support growth, as well as higher incentive compensation related to achievement of performance targets. The Company’s operating efficiency ratio¹ on a tax equivalent basis was 40.0% for the third quarter 2017, compared to 41.2% for the second quarter 2017, and 43.0% for the third quarter 2016.

Net income was $82.9 million for the third quarter 2017, an increase of $2.9 million, or 3.6%, from $80.0 million for the second quarter 2017, and an increase of $15.8 million, or 23.6%, from $67.1 million for the third quarter 2016. Earnings per share was $0.79 for the third quarter 2017, compared to $0.76 for the second quarter 2017, and $0.64 for the third quarter 2016.

The Company views its operating pre-provision net revenue ("PPNR") as a key metric for assessing the Company’s earnings power, which it defines as net operating revenue less operating non-interest expense. For the third quarter 2017, the Company’s operating PPNR was $122.7 million, up 6.5% from $115.2 million in the second quarter 2017, and up 21.7% from $100.8 million in the third quarter 2016.¹ The non-operating items¹ for the third quarter 2017 consisted primarily of a net gain on sales of investment securities of $0.3 million, offset by a net loss on sales / valuations of repossessed and other assets of $0.3 million. The non-operating items¹ for the third quarter 2016 consisted primarily of acquisition / restructure expenses of $2.7 million related to the HFF and system conversion costs.

The Company had 1,673 full-time equivalent employees and 47 offices at September 30, 2017, compared to 1,628 employees and 46 offices at June 30, 2017 and 1,520 employees and 48 offices at September 30, 2016.

Balance Sheet

Gross loans totaled $14.52 billion at September 30, 2017, an increase of $532 million from $13.99 billion at June 30, 2017, and an increase of $1.49 billion from $13.03 billion at September 30, 2016. The increase from both the prior quarter and from September 30, 2016 is due to organic loan growth. At September 30, 2017, the allowance for credit losses to gross loans held for investment was 0.94%, compared to 0.94% at June 30, 2017, and 0.94% at September 30, 2016. At September 30, 2017, the allowance for credit losses to total organic loans was 1.06%, compared to 1.08% at June 30, 2017, and 1.13% at September 30, 2016. The Company defines its organic loans as those loans that have not been acquired in a transaction accounted for as a business combination.

Consistent with accounting principles generally accepted in the United States ("GAAP"), the allowance for credit losses is not carried over in an acquisition because acquired loans are recorded at fair value, which discounts the loans based on expected future cash flows. Credit discounts on acquired loans are included as a reduction to gross loans. These discounts totaled $32.7 million at September 30, 2017, compared to $37.8 million at June 30, 2017, and $56.1 million at September 30, 2016.

Deposits totaled $16.90 billion at September 30, 2017, an increase of $874 million from $16.03 billion at June 30, 2017, and an increase of $2.46 billion from $14.44 billion at September 30, 2016. The increase from both the prior quarter and from September 30, 2016 is the result of organic deposit growth. Non-interest bearing deposits were $7.61 billion at September 30, 2017, compared to $6.86 billion at June 30, 2017, and $5.62 billion at September 30, 2016. Non-interest bearing deposits comprised 45.0% of total deposits at September 30, 2017, compared to 42.8% at June 30, 2017, and 38.9% at September 30, 2016. The proportion of savings and money market balances to total deposits decreased to 37.3% from 38.1% at June 30, 2017, and from 41.3% at September 30, 2016. Certificates of deposit as a percentage of total deposits were 9.4% at September 30, 2017, compared to 9.9% at June 30, 2017, and 11.0% at September 30, 2016. The Company’s ratio of loans to deposits was 85.9% at September 30, 2017, compared to 87.3% at June 30, 2017, and 90.2% at September 30, 2016.

Qualifying debt totaled $373 million at September 30, 2017, compared to $375 million at June 30, 2017, and $383 million at September 30, 2016.

Stockholders’ equity at September 30, 2017 was $2.15 billion, compared to $2.06 billion at June 30, 2017, and $1.86 billion at September 30, 2016. The increase from the prior quarter and prior year relates primarily to net income for the respective period.

At September 30, 2017, tangible common equity, net of tax, was 9.4% of tangible assets¹ and total capital was 13.3% of risk-weighted assets. The Company’s tangible book value per share¹ was $17.53 at September 30, 2017, up 18.1% from September 30, 2016.

Total assets increased 5.7% to $19.92 billion at September 30, 2017, from $18.84 billion at June 30, 2017, and increased 16.9% from $17.04 billion at September 30, 2016. The increase in total assets from the prior quarter and prior year relates primarily to loan growth of $532 million and $1.49 billion, respectively.

Asset Quality

The provision for credit losses was $5.0 million for the third quarter 2017, compared to $3.0 millionfor the second quarter 2017, and $2.0 million for the third quarter 2016. Net charge-offs (recoveries) in the third quarter 2017 were $0.4 million, or 0.01% of average loans (annualized), compared to $(1.2) million in net recoveries, or (0.03)%, in the second quarter 2017 and $1.2 million in net charge-offs, or 0.04%, in the third quarter 2016.

Nonaccrual loans increased $24.9 million to $55.0 million during the quarter, which primarily relates to one loan with a net balance of $23 million, which the Company sold subsequent to quarter end. The Company incurred a loss of $1.4 million on the sale of the loan, which was recognized as a charge-off during the quarter. Loans past due 90 days and still accruing interest totaled less than $0.1 million at September 30, 2017, compared to $4.0 million at June 30, 2017, and $2.8 million at September 30, 2016. Loans past due 30-89 days and still accruing interest totaled $5.2 million at quarter end, an increase from $4.1 million at June 30, 2017, and a decrease from $18.4 million at September 30, 2016.

Repossessed assets totaled $29.0 million at quarter end, a decrease of $2.0 million from $31.0 million at June 30, 2017, and a decrease of $20.6 million from $49.6 million at September 30, 2016. Adversely graded loans and non-performing assets totaled $406.2 million at quarter end, an increase of $38.4 million from $367.8 million at June 30, 2017, and an increase of $71.3 million from $334.9 million at September 30, 2016. The increase in non-performing assets during the quarter primarily relates to the $23 million loan discussed above.

As the Company’s asset quality and capital remain strong, the ratio of classified assets to Tier I capital plus the allowance for credit losses, a common regulatory measure of asset quality, was 10.7% at September 30, 2017, compared to 12.7% at June 30, 2017, and 12.3% at September 30, 2016.¹

The Company's NBL reportable segments include Homeowner Associations ("HOA") Services, Hotel Franchise Finance ("HFF"), Public & Nonprofit Finance, Technology & Innovation, and Other NBLs.

The HOA Services NBL corresponds to the Alliance Association Bank division. The HFF NBL includes the hotel franchise loan portfolio purchased from GE Capital on April 20, 2016. The operations of Public and Nonprofit Finance are combined into one reportable segment. The Technology & Innovation NBL includes the operations of Equity Fund Resources, the Life Sciences Group, the Renewable Resource Group, and Technology Finance. The Other NBLs segment consists of the operations of Corporate Finance, Mortgage Warehouse Lending, and Resort Finance.

The Corporate & Other segment consists of corporate-related items, income and expense items not allocated to our other reportable segments, and inter-segment eliminations.

Key management metrics for evaluating the performance of the Company's Arizona, Nevada, Southern California, Northern California, and NBL segments include loan and deposit growth, asset quality, and pre-tax income.

During the quarter, the Technology & Innovation segment increased deposits by $187 million, which was partially offset by a decrease of $34 million in HOA Services.

Non-GAAP Financial Measures Footnotes		��
(1)	We believe these non-GAAP measurements provide a useful indication of the cash generating capacity of the Company.
(2)	We believe this non-GAAP measurement is a key indicator of the earnings power of the Company.
(3)	We believe this non-GAAP ratio provides an important metric with which to analyze and evaluate financial condition and capital strength.
(4)	We believe this non-GAAP measurement improves the comparability to other institutions that have not engaged in acquisitions that resulted in recorded goodwill and other intangibles.
(5)	We believe this non-GAAP ratio provides a useful metric to measure the operating efficiency of the Company.
(6)	Under the current guidelines of the Federal Reserve and the Federal Deposit Insurance Corporation, common equity Tier 1 capital consists of common stock, retained earnings, and minority interests in certain subsidiaries, less most other intangible assets.
(7)	Common equity Tier 1 is often expressed as a percentage of risk-weighted assets. Under the risk-based capital framework, a bank's balance sheet assets and credit equivalent amounts of off-balance sheet items are assigned to one of the risk categories defined under new capital guidelines. The aggregated dollar amount in each category is then multiplied by the risk weighting assigned to that category. The resulting weighted values from each category are added together and this sum is the risk-weighted assets total that, as adjusted, comprises the denominator (risk-weighted assets) to determine the common equity Tier 1 ratio. Common equity Tier 1 is divided by the risk-weighted assets to determine the common equity Tier 1 ratio. We believe this non-GAAP ratio provides an important metric with which to analyze and evaluate financial condition and capital strength.
(8)	We believe this non-GAAP ratio provides an important regulatory metric to analyze asset quality.
(9)	Current quarter is preliminary until Call Report is filed.
