Accounting Policies [Abstract]
Basis of Presentation	NOTE 1: BASIS OF PRESENTATION The consolidated financial statements include First Foundation Inc. (“FFI”) and its wholly owned subsidiaries: First Foundation Advisors (“FFA”) and First Foundation Bank (“FFB” or the “Bank”) and the wholly owned subsidiaries of FFB, First Foundation Insurance Services (“FFIS”) and Blue Moon Management, LLC (collectively referred to as the “Company”). All inter-company balances and transactions have been eliminated in consolidation. The results of operations reflect any interim adjustments, all of which are of a normal recurring nature and which, in the opinion of management, are necessary for a fair presentation of the results for the interim period presented. The results for the 2018 interim periods are not necessarily indicative of the results expected for the full year. The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America and prevailing practices within the banking industry. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and revenues and expenses for the period. Actual results could differ significantly from those estimates. The accompanying unaudited consolidated financial statements include all information and footnotes required for interim financial statement presentation. These financial statements assume that readers have read the most recent Annual Report on Form 10-K which contains the latest available audited consolidated financial statements and notes thereto as of and for the year ended December 31, 2017. Certain reclassifications have been made to the prior year consolidated financial statements to conform to the 2018 presentation. In August 2018, the FASB issued guidance within ASU 2018-13, Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement . The amendments within ASU 2018-13 remove, modify, and supplement the disclosure requirements for fair value measurements. Disclosure requirements that were removed include: the amount and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, the policy for timing of transfers between levels, and the valuation processes for Level 3 fair value measurements. The amendments clarify that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date. Additional disclosure requirements include: the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period, and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. With the exception of the above additional disclosure requirements, which will be applied prospectively, all other amendments should be applied retrospectively to all periods presented upon their effective date. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. The adoption of this guidance is not expected to have a significant impact on the Company's consolidated financial statements. In February 2017, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ ASU”) “Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets” In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (Topic 815) – Targeted Improvements to Accounting for Hedging Activities” In January 2017, the FASB issued ASU “Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment” In June 2016, the FASB issued ASU “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases Leases (Topic 842), Targeted Improvements Leases (Topic 842) In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) The amendments in this update are effective for interim and annual periods beginning after December 15, 2018. We expect the adoption of ASU 2016-02 to impact the Company’s accounting for its building leases at each of its locations through an increase in assets and liabilities by approximately $20 million to $25 million In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities” (“ASU 2016-01”). The guidance affects the accounting for equity investments and adjusts the fair value disclosures for financial instruments carried at amortized cost such that the disclosed fair values represent an exit price as opposed to an entry price. ASU 2016-01 was effective for the Company on January 1, 2018 and resulted in separate classification of equity securities with changes in the fair value of the equity securities captured in the consolidated statements of income. The adoption of ASU 2016-01 did not have a material effect on the Company’s financial statements and disclosures. In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)” Wealth management and trust fee income Asset management fees are billed on a monthly or quarterly basis based on the amount of assets under management and the applicable contractual fee percentage. Asset management fees are recognized as revenue in the period in which they are billed and earned. Financial planning fees are due and billed at the completion of the planning project and are recognized as revenue at that time. Service charges on deposit accounts Service charges on deposit accounts represent general service fees for monthly account maintenance and activity or transaction-based fees. Revenue is recognized when our performance obligation is completed which is generally monthly for account maintenance services or when a transaction has been completed. Payment for such performance obligations are generally received at the time the performance obligations are satisfied. Gains and Losses on Sales of REO The new guidance requires judgment in evaluating if: (a) a commitment on the buyer’s part exists, (b) collection is probable in circumstances where the initial investment is minimal and (c) the buyer has obtained control of the asset, including the significant risks and rewards of the ownership. If there is no commitment on the buyer’s part, collection is not probable or the buyer has not obtained control of the asset, then a gain cannot be recognized. The initial investment requirement for the buyer along with the various methods for profit recognition are no longer applicable. The Company does not expect the new guidance to have a significant impact on the consolidated financial statements. Other non-interest income includes revenue related to mortgage servicing activities and gains on sales of loans, which are not subject to the requirements of ASU 2014-09.

Business Combinations [Abstract]
Acquisitions	NOTE 2: ACQUISITIONS On June 1, 2018, the Company completed the acquisition of PBB Bancorp and its wholly owned subsidiary Premier Business Bank (collectively “PBB”), through a merger of PBB with and into the Bank, in exchange for 5,234,593 shares of its common stock with a fair value of $19.39 per share. The primary reason for acquiring PBB was to expand our operations in Southern California. The acquisition is accounted for under the purchase method of accounting. The acquired assets, assumed liabilities and identifiable intangible assets are recorded at their respective acquisition date fair values. Goodwill of $61 million, which is not tax deductible, is included in intangible assets in the table below. The following table represents the assets acquired and liabilities assumed of PBB as of June 1, 2018 and the fair value adjustments and amounts recorded by the Bank in 2018 under the acquisition method of accounting: (dollars in thousands) PBB Book Value Fair Value Adjustments Fair Value Assets Acquired: Cash and cash equivalents $ 47,582 $ — $ 47,582 Securities AFS 10,072 (90 ) 9,982 Loans, net of deferred fees 537,885 (14,986 ) 522,899 Allowance for loan losses (3,011 ) 3,011 — Premises and equipment, net 3,811 (1,536 ) 2,275 Investment in FHLB stock 3,229 — 3,229 Deferred taxes 1,451 2,398 3,849 REO 934 (109 ) 825 Goodwill and Core deposit intangible 634 66,615 67,249 Other assets 6,634 (566 ) 6,068 Total assets acquired $ 609,221 $ 54,737 $ 663,958 Liabilities Assumed: Deposits $ 477,366 $ 219 $ 477,585 Borrowings 79,911 (341 ) 79,570 Accounts payable and other liabilities 5,204 100 5,304 Total liabilities assumed 562,481 (22 ) 562,459 Excess of assets acquired over liabilities assumed 46,740 54,759 101,499 Total $ 609,221 $ 54,737 $ 663,958 Consideration: Stock issued $ 101,499 In many cases, the fair values of assets acquired and liabilities assumed were determined by estimating the cash flows expected to result from those assets and liabilities and discounting them at appropriate market rates. The most significant category of assets for which this procedure was used was that of acquired loans. The excess of expected cash flows above the fair value of the majority of loans will be accreted to interest income over the remaining lives of the loans in accordance with FASB Accounting Standards Codification (“ASC”) 310-20. Certain loans, for which specific credit-related deterioration since origination was identified, are recorded at fair value reflecting the present value of the amounts expected to be collected. Income recognition on these “purchased credit impaired” loans is based on a reasonable expectation about the timing and amount of cash flows to be collected. Acquired loans deemed impaired and considered collateral dependent, with the timing of the sale of loan collateral indeterminate, remain on nonaccrual status and have no accretable yield. All purchased credit impaired loans were classified as accruing loans as of and subsequent to the acquisition date. In accordance with generally accepted accounting principles there was no carryover of the allowance for loan losses that had been previously recorded by PBB. The Company recorded a deferred income tax asset of $3.8 million related to PBB’s operating loss carry-forward and other tax attributes of PBB, along with the effects of fair value adjustments resulting from applying the purchase method of accounting. The fair value of savings and transaction deposit accounts acquired from PBB were assumed to approximate their carrying value as these accounts have no stated maturity and are payable on demand. Certificates of deposit accounts were valued by comparing the contractual cost of the portfolio to an identical portfolio bearing current market rates. The portfolio was segregated into pools based on remaining maturity. For each pool, the projected cash flows from maturing certificates were then calculated based on contractual rates and prevailing market rates. The valuation adjustment for each pool is equal to the present value of the difference of these two cash flows, discounted at the assumed market rate for a certificate with a corresponding maturity. This valuation adjustment will be accreted to reduce interest expense over the remaining maturities of the respective pools. The Company also recorded a core deposit intangible, which represents the value of the deposit relationships acquired from PBB, of $6.7 million. The core deposit intangible will be amortized over a period of 10 years. Pro Forma Information (unaudited) The following table presents unaudited pro forma information for the nine months periods ending September 30, 2018 as if the acquisition of PBB had occurred on January 1, 2018, and unaudited pro forma information for the nine months periods ending September 30, 2017 as if the acquisition of Community 1 st Nine Months Ended September 30, (dollars in thousands) 2018 2017 Net interest income $ 125,700 $ 110,320 Provision for loan losses 4,147 2,482 Noninterest income 27,837 29,574 Noninterest expenses 100,564 88,862 Income before taxes 48,826 48,550 Taxes on income 13,676 16,824 Net income $ 35,150 $ 31,726 Net income per share: Basic $ 0.80 $ 0.76 Diluted $ 0.79 $ 0.74 The revenues (net interest income and noninterest income) and net income for the period from June 1, 2018 to September 30, 2018 related to the operations acquired from PBB and included in our results of operations for the nine months ended September 30, 2018 were approximately $10.5 million and $7.3 million, respectively.

Fair Value Measurements

Fair Value Measurements	9 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	NOTE 3 : FAIR VALUE MEASUREMENTS Assets Measured at Fair Value on a Recurring Basis F air value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Current accounting guidance establishes a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair values: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect the Company's own assumptions about the assumptions that market participants would use in pricing an asset or liability. Assets Measured at Fair Value on a Recurring Basis Securities available for sale and effective with the adoption of ASU 2016-01 on January 1, 2018, investments in equity securities, are measured at fair value on a recurring basis depending upon whether the inputs are Level 1, 2 or 3 as described above. The Fair Value Measurement Level (dollars in thousands) Total Level 1 Level 2 Level 3 September 30, 2018: Investment securities available for sale: Agency mortgage-backed securities $ 727,017 $ — $ 727,017 $ — Corporate bonds 38,922 — 38,922 — Beneficial interest – FHLMC securitizations 32,490 — — 32,490 Other 1,441 1,441 — — Investment in equity securities 1,312 1,312 — — Total assets at fair value on a recurring basis $ 801,182 $ 2,753 $ 765,939 $ 32,490 December 31, 2017: Investment securities available for sale: Agency mortgage-backed securities $ 464,019 — 464,019 — Corporate bonds 19,000 — 19,000 — Beneficial interest – FHLMC securitizations 35,852 — — 35,852 Other 493 493 — — Investment in equity securities 514 514 — — Total assets at fair value on a recurring basis $ 519,878 $ 1,007 $ 483,019 $ 35,852 The decrease in level 3 assets from December 31, 2017 was due to beneficial interest – FHLMC securitization maturities. Assets Measured at Fair Value on a Nonrecurring Basis Additionally, from time to time, we may be required to measure other assets at fair value on a nonrecurring basis. These nonrecurring fair value adjustments typically involve application of lower of cost or market accounting or write-downs of individual assets. Impaired Loans . ASC 820-10 applies to loans measured for impairment in accordance with ASC 310-10, “Accounting by Creditors for Impairment of a Loan”, at the fair value of the loan’s collateral (if the loan is collateral dependent) less estimated selling costs. When the fair value of the collateral is based on an observable market price or a current appraised value, we measure the impaired loan at nonrecurring Level 2. When an appraised value is not available, or management determines the fair value of the collateral is further impaired below the appraised value and there is no observable market price or a discounted cash flow has been used to determine the fair value, we measure the impaired loan at nonrecurring Level 3. The total collateral dependent impaired Level 3 loans were $12.5 million and $13.4 million at September 30, 2018 and December 31, 2017, respectively. There were $0.8 million and $0.9 million of specific reserves related to these loans at both September 30, 2018 and December 31, 2017. Real Estate Owned . The fair value of real estate owned is based on external appraised values that include adjustments for estimated selling costs and assumptions of market conditions that are not directly observable, resulting in a Level 3 classification. As of September 30, 2018 and December 31, 2017, the fair value of real estate owned was $2.0 million and $2.9 million, respectively. Fair Value of Financial Instruments Fair value estimates are made at a discrete point in time based on relevant market information and other information about the financial instruments. Considerable judgment is required to interpret market data to develop estimates of fair value. These estimates are subjective in nature and invariably involve some inherent uncertainties. Additionally, unexpected events or changes in circumstances can occur that could require us to make changes to our assumptions and which, in turn, could significantly affect and require us to make changes to our previous estimates of fair value. The methods of determining the fair value of assets and liabilities presented in this note as of September 30, 2018 are consistent with Note 3 of the Company’s 2017 Form 10-K except for the valuation of investment in equity securities. We refined the calculation used to determine the disclosed fair value of our investment in equity securities as part of adopting ASU 2016-01. The refined calculation did not have a significant impact on our fair value disclosures. The carrying amounts and estimated fair values of financial instruments are as follows as of: Carrying Fair Value Measurement Level (dollars in thousands) Value 1 2 3 Total September 30, 2018: Assets: Cash and cash equivalents $ 54,935 $ 54,935 $ — $ — $ 54,935 Securities AFS 799,870 1,441 765,939 32,490 799,870 Loans, net 4,431,859 — — 4,401,756 4,401,756 Investment in FHLB stock 17,250 — 17,250 — 17,250 Investment in equity securities 1,312 1,312 — — 1,312 Liabilities: Deposits 4,668,707 2,899,208 1,767,610 — 4,666,818 Borrowings 232,000 — 197,000 35,000 232,000 December 31, 2017: Assets: Cash and cash equivalents $ 120,394 $ 120,394 $ — $ — $ 120,394 Securities AFS 519,364 493 483,019 35,852 519,364 Loans, held for sale 154,380 — 155,345 — 154,345 Loans, net 3,645,327 — — 3,617,060 3,617,060 Investment in FHLB stock 19,060 — 19,060 — 19,060 Investment in equity securities 514 514 — — 514 Liabilities: Deposits 3,443,527 2,542,730 901,877 — 3,444,607 Borrowings 678,000 — 628,000 50,000 678,000

The discount is equal to 0.69% and 1.15% of the stated principal balance of these loans as of September 30, 2018 and December 31, 2017, respectively. In addition to this unaccreted credit component discount, an additional $0.3 million and $0.2 million of ALLL has been provided for these loans as of September 30, 2018 and December 31, 2017, respectively. The Bank categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as current financial information, historical payment experience, collateral adequacy, credit documentation, and current economic trends, among other factors. The Bank analyzes loans individually by classifying the loans as to credit risk. This analysis typically includes larger, non-homogeneous loans such as loans secured by multifamily or commercial real estate and commercial and industrial loans. This analysis is performed on an ongoing basis as new information is obtained. The Bank uses the following definitions for risk ratings: Pass: Loans classified as pass are strong credits with no existing or known potential weaknesses deserving of management’s close attention. Special Mention: Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date. Substandard: Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Impaired: A loan is considered impaired, when, based on current information and events, it is probable that the Bank will be unable to collect all amounts due according to the contractual terms of the loan agreement. Additionally, all loans classified as TDRs are considered impaired at the time they are restructured. Purchased credit impaired loans are not considered impaired loans for these purposes. Loans listed as pass include larger non-homogeneous loans not meeting the risk rating definitions above and smaller, homogeneous loans not assessed on an individual basis. Based on the most recent analysis performed, the risk category of loans by class of loans is as follows as of: (dollars in thousands) Pass Special Substandard Impaired Total September 30, 2018: Real estate loans: Residential properties $ 3,079,406 $ 3,694 $ 2,383 $ 675 $ 3,086,158 Commercial properties 820,094 11,086 7,819 2,924 841,923 Land 77,650 — 816 — 78,466 Commercial and industrial loans 393,235 6,879 1,820 8,936 410,870 Consumer loans 23,471 — — — 23,471 Total $ 4,393,856 $ 21,659 $ 12,838 $ 12,535 $ 4,440,888 December 31, 2017: Real estate loans: Residential properties $ 2,578,773 $ 192 $ 2,280 $ — $ 2,581,245 Commercial properties 680,449 6,326 5,936 4,037 696,748 Land 36,321 — 839 — 37,160 Commercial and industrial loans 298,408 865 2,107 9,399 310,779 Consumer loans 29,330 — — — 29,330 Total $ 3,623,281 $ 7,383 $ 11,162 $ 13,436 $ 3,655,262 Impaired loans evaluated individually and any related allowance are as follows as of: With No Allowance Recorded With an Allowance Recorded (dollars in thousands) Unpaid Principal Balance Recorded Investment Unpaid Principal Balance Recorded Investment Related Allowance September 30, 2018 : Real estate loans: Residential properties $ 675 $ 675 $ — $ — $ — Commercial properties 1,642 1,642 1,282 1,282 104 Commercial and industrial loans 2,353 2,353 6,583 6,583 713 Total $ 4,670 $ 4,670 $ 7,865 $ 7,865 $ 817 December 31, 2017 : Real estate loans: Commercial properties $ 4,037 $ 4,037 $ — $ — $ — Commercial and industrial loans 250 250 9,149 9,149 909 Total $ 4,287 $ 4,287 $ 9,149 $ 9,149 $ 909 The weighted average annualized average balance of the recorded investment for impaired loans, beginning from when the loan became impaired, and any interest income recorded on impaired loans after they became impaired is as follows for the: Nine months Ended Year Ended (dollars in thousands) Average Recorded Investment Interest Income after Impairment Average Recorded Investment Interest Income after Impairment Real estate loans: Residential properties $ 150 $ — $ 1,323 $ 20 Commercial properties 3,647 67 2,403 50 Commercial and industrial loans 9,239 — 5,503 5 Total $ 13,036 $ 67 $ 9,229 $ 75 There was no interest income recognized on a cash basis in either 2018 or 2017 on impaired loans.

Loan Sales and Mortgage Servicing Rights	NOTE 7: LOAN SALES AND MORTGAGE SERVICING RIGHTS During the first nine months of 2018, FFB recognized $0.4 million of gains on the sale of $674 million of multifamily loans and recorded mortgage servicing rights of $2.6 million on the sale of those loans. In 2017, FFB sold $453 million of multifamily loans to financial institutions and recognized a gain of $7.0 million. For the sales of multifamily loans, FFB retained servicing rights for the majority of these loans and recognized mortgage servicing rights as part of the transactions. As of September 30, 2018 and December 31, 2017, mortgage servicing rights were $6.8 million and $4.8 million, respectively and the amount of loans serviced for others totaled $1.4 billion and $0.7 billion at September 30, 2018 and December 31, 2017, respectively. Servicing fees collected for the nine months ended September 30, 2018, and in 2017 were $0.7 million for both periods. During the second quarter of 2018, we entered into swap agreements with notional amounts of $651 million which were closed out in the third quarter of 2018. As a result of the swap, our interest income on loans was reduced by $0.8 million for the period in which the swap was in place. The value of the swap at close out was $5.9 million, which offset decreases in the value of the loans sold during the period in which the swap was in place.

Borrowings	NOTE 9: BORROWINGS At September 30, 2018, our borrowings consisted of $192 million of overnight FHLB advances and $5 million in FHLB term borrowings at the Bank and $35 million of borrowings under a holding company line of credit. At December 31, 2017, our borrowings consisted of $628 million of overnight FHLB advances at the Bank and $50 million outstanding on a holding company line of credit. The overnight FHLB advances were paid in full in the early part of October 2018 and January 2018, respectively, and bore interest rates of 2.33% and 1.41%, respectively. At September 30, 2018, the interest rate on the holding company line of credit was 5.84%. Because the Bank utilizes overnight borrowings, the balance of outstanding borrowings fluctuates on a daily basis. FHLB advances are collateralized primarily by loans secured by multifamily and commercial real estate properties with a carrying value of $3.2 billion as of September 30, 2018. As a matter of practice, the Bank provides substantially all of its qualifying loans as collateral to the FHLB. The Bank’s total borrowing capacity from the FHLB at September 30, 2018 was $2.4 billion. In addition to the $197 million borrowing at September 30, 2018, the Bank had in place $201 million of letters of credit from the FHLB which are used to meet collateral requirements for borrowings from the State of California and local agencies. During 2017, FFI entered into a loan agreement with an unaffiliated lender that provided for a revolving line of credit for up to $50 million. The loan agreement matures in five years, with an option to extend the maturity date subject to certain conditions, and bears interest at 90 day LIBOR plus 350 basis points (3.50%). We are required to meet certain financial covenants during the term of the loan, including minimum capital levels and limits on classified assets. FFI’s obligations under the loan agreement are secured by, among other things, a pledge of all of its equity in FFB. In April 2018, the maximum amount under the line was increased by $25 million, to $75 million. The Bank also has $120 million available borrowing capacity through unsecured fed funds lines, ranging in size from $20 million to $25 million, with five other financial institutions and a $95 million secured line with the Federal Reserve Bank. None of these lines had outstanding borrowings as of September 30, 2018. Combined, the Bank’s unused lines of credit as of September 30, 2018 and December 31, 2017 were $2.2 billion and $943 million, respectively. The average balance of overnight borrowings during the first nine months of 2018 was $607 million, as compared to $499 million during all of 2017.

Earnings Per Share [Abstract]
Earnings Per Share	NOTE 10: EARNINGS PER SHARE Basic earnings per share excludes dilution and is computed by dividing net income or loss available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution that could occur if contracts to issue common stock were exercised or converted into common stock that would then share in earnings. The following table sets forth the Company’s unaudited earnings per share calculations for the periods indicated: Quarter Ended September 30, 2018 Quarter Ended September 30, 2017 (dollars in thousands, except per share amounts) Basic Diluted Basic Diluted Net income $ 14,707 $ 14,707 $ 9,580 $ 9,580 Basic common shares outstanding 44,405,094 44,405,094 34,565,949 34,565,949 Effect of contingent shares issuable 1,592 1,592 Effect of options and restricted stock 445,421 692,091 Diluted common shares outstanding 44,852,107 35,259,632 Earnings per share $ 0.33 $ 0.33 $ 0.28 $ 0.27 Nine Months Ended September 30, 2018 Nine Months Ended September 30, 2017 (dollars in thousands, except per share amounts) Basic Diluted Basic Diluted Net income $ 28,829 $ 28,829 $ 25,309 $ 25,309 Basic common shares outstanding 41,288,804 41,288,804 33,671,327 33,671,327 Effect of contingent shares issuable 1,592 1,592 Effect of options and restricted stock 500,260 926,894 Diluted common shares outstanding 41,790,656 34,599,813 Earnings per share $ 0.70 $ 0.69 $ 0.75 $ 0.73
