The accompanying unaudited Consolidated Financial Statements were prepared in accordance with GAAP and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the Corporation’s Consolidated Financial Statements and footnotes thereto included in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2015 . The unaudited Consolidated Financial Statements include the accounts of the Corporation and its wholly owned subsidiaries. In accordance with the provisions of Accounting Standards Codification (“ASC”) Topic 810, the Corporation’s ownership interest in FBFS Statutory Trust II (“Trust II”) has not been consolidated into the financial statements. All significant intercompany balances and transactions have been eliminated in consolidation. Management of the Corporation is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements as well as reported amounts of revenues and expenses during the reporting period. Actual results could differ significantly from those estimates. Material estimates that could significantly change in the near-term include the value of lease residuals, property under operating leases, securities, income taxes, goodwill and the level of the allowance for loan and lease losses. The results of operations for the nine month period ended September 30, 2016 are not necessarily indicative of results that may be expected for any other interim period or the entire fiscal year ending December 31, 2016 . Certain amounts in prior periods may have been reclassified to conform to the current presentation. Subsequent events have been evaluated through the date of the issuance of the unaudited Consolidated Financial Statements. No significant subsequent events have occurred through this date requiring adjustment to the financial statements or disclosures. The Corporation has not changed its significant accounting and reporting policies from those disclosed in the Corporation’s Form 10-K for the year ended December 31, 2015 except as described further below in this Note 1 . Recent Accounting Pronouncements In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230). The ASU provides guidance on eight specific cash flow issues with the objective of reducing diversity in practice. The ASU is effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. The amendments in this update will be applied retrospectively to each prior period presented. The Corporation intends to adopt the accounting standard during the first quarter of 2018, as required, and is currently evaluating the impact on its results of operations, financial position and liquidity.

Earnings Per Common Share

Earnings Per Common Share	9 Months Ended

Earnings Per Share [Abstract]
Earnings Per Common Share	Earnings Per Common Share Earnings per common share are computed using the two-class method. Basic earnings per common share are computed by dividing net income allocated to common shares by the weighted average number of shares outstanding during the applicable period, excluding outstanding participating securities. Participating securities include unvested restricted shares. Unvested restricted shares are considered participating securities because holders of these securities receive non-forfeitable dividends, or dividend equivalents, at the same rate as holders of the Corporation’s common stock. Diluted earnings per share are computed by dividing net income allocated to common shares, adjusted for reallocation of undistributed earnings of unvested restricted shares, by the weighted average number of shares determined for the basic earnings per common share computation plus the dilutive effect of common stock equivalents using the treasury stock method. There were no anti-dilutive employee share-based awards for the three and nine month periods ended September 30, 2016 and 2015 . For the Three Months Ended September 30, For the Nine Months Ended September 30, 2016 2015 2016 2015 (Dollars in Thousands, Except Per Share Data) Basic earnings per common share Net income $ 2,540 $ 4,381 $ 10,803 $ 12,431 Less: earnings allocated to participating securities 38 68 165 206 Basic earnings allocated to common shareholders $ 2,502 $ 4,313 $ 10,638 $ 12,225 Weighted-average common shares outstanding, excluding participating securities 8,582,836 8,546,563 8,569,613 8,538,219 Basic earnings per common share $ 0.29 $ 0.50 $ 1.24 $ 1.43 Diluted earnings per common share Earnings allocated to common shareholders, diluted $ 2,502 $ 4,313 $ 10,638 $ 12,225 Weighted-average common shares outstanding, excluding participating securities 8,582,836 8,546,563 8,569,613 8,538,219 Dilutive effect of share-based awards — — — 1,486 Weighted-average diluted common shares outstanding, excluding participating securities 8,582,836 8,546,563 8,569,613 8,539,705 Diluted earnings per common share $ 0.29 $ 0.50 $ 1.24 $ 1.43

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-Based Compensation	Share-Based Compensation The Corporation adopted the 2012 Equity Incentive Plan (the “Plan”) during the quarter ended June 30, 2012. The Plan is administered by the Compensation Committee of the Board of Directors of the Corporation and provides for the grant of equity ownership opportunities through incentive stock options and nonqualified stock options (together, “Stock Options”), restricted stock, restricted stock units, dividend equivalent units and any other type of award permitted by the Plan. As of September 30, 2016 , 273,737 shares were available for future grants under the Plan. Shares covered by awards that expire, terminate or lapse will again be available for the grant of awards under the Plan. The Corporation may issue new shares and shares from its treasury stock for shares delivered under the Plan. Restricted Stock Under the Plan, the Corporation may grant restricted stock to plan participants, subject to forfeiture upon the occurrence of certain events until the dates specified in the participant’s award agreement. While restricted stock is subject to forfeiture, with the exception of restricted stock units, which do not have voting rights and are provided dividend equivalents, restricted stock participants may exercise full voting rights and will receive all dividends and other distributions paid with respect to the restricted shares. The restricted stock granted under the Plan is typically subject to a vesting period. Compensation expense is recognized over the requisite service period of generally four years for the entire award on a straight-line basis. Upon vesting of restricted share awards, the benefit of tax deductions in excess of recognized compensation expense is recognized as a financing cash flow activity. Restricted stock activity for the year ended December 31, 2015 and the nine months ended September 30, 2016 was as follows: Number of Restricted Shares/Units Weighted Average Grant-Date Fair Value Nonvested balance as of December 31, 2014 154,998 $ 16.97 Granted 53,790 22.52 Vested (64,874 ) 15.23 Forfeited (8,443 ) 15.03 Nonvested balance as of December 31, 2015 135,471 20.13 Granted 50,700 22.98 Vested (53,000 ) 18.73 Forfeited (12,992 ) 18.96 Nonvested balance as of September 30, 2016 120,179 $ 21.22 As of September 30, 2016 , the Corporation had $2.4 million of deferred unvested compensation expense, which the Corporation expects to recognize over a weighted-average period of approximately 2.80 years. For the three and nine months ended September 30, 2016 and 2015 , share-based compensation expense related to restricted stock included in the unaudited Consolidated Statements of Income was as follows: For the Three Months Ended September 30, For the Nine Months Ended September 30, 2016 2015 2016 2015 (In Thousands) Share-based compensation expense $ 292 $ 268 $ 858 $ 717

Collateralized mortgage obligations - government issued represent securities guaranteed by the Government National Mortgage Association (“GNMA”). Collateralized mortgage obligations - government-sponsored enterprises include securities guaranteed by the FHLMC and the FNMA. Asset-backed securities represent securities issued by the Student Loan Marketing Association (“SLMA”) which are 97% guaranteed by the U.S. Government. Municipal obligations include securities issued by various municipalities located primarily within the State of Wisconsin and are primarily general obligation bonds that are tax-exempt in nature. For the nine months ended September 30, 2016 , a gain of $7,000 was recorded from the sale of three available-for-sale securities. No sales of available-for-sale securities occurred during the nine months ended September 30, 2015 . At September 30, 2016 and December 31, 2015 , securities with a fair value of $20.2 million and $23.0 million , respectively, were pledged to secure interest rate swap contracts, outstanding Federal Home Loan Bank (“FHLB”) advances, if any, and additional FHLB availability. The amortized cost and fair value of securities by contractual maturity at September 30, 2016 are shown below. Actual maturities may differ from contractual maturities because issuers have the right to call or prepay certain obligations without call or prepayment penalties.

At September 30, 2016 , the Corporation held 48 available-for-sale securities that were in an unrealized loss position. Such securities have not experienced credit rating downgrades; however, they have primarily declined in value due to the current interest rate environment. At September 30, 2016 , the Corporation held eight available-for-sale securities that had been in a continuous unrealized loss position for twelve months or greater. The Corporation also has not specifically identified available-for-sale securities in a loss position that it intends to sell in the near term and does not believe that it will be required to sell any such securities. The Corporation reviews its securities on a quarterly basis to monitor its exposure to other-than-temporary impairment. Consideration is given to such factors as the length of time and extent to which the security has been in an unrealized loss position, changes in security ratings and an evaluation of the present value of expected future cash flows, if necessary. Based on the Corporation’s evaluation, it is expected that the Corporation will recover the entire amortized cost basis of each security. Accordingly, no other than temporary impairment was recorded in the unaudited Consolidated Statements of Income for the nine months ended September 30, 2016 and 2015 . A summary of unrealized loss information for securities available-for-sale, categorized by security type and length of time for which the security has been in a continuous unrealized loss position follows: As of September 30, 2016 Less than 12 months 12 months or longer Total Fair value Unrealized losses Fair value Unrealized losses Fair value Unrealized losses (In Thousands) Available-for-sale: U.S. Government agency obligations - government-sponsored enterprises $ 1,000 $ — $ — $ — $ 1,000 $ — Municipal obligations 4,516 13 409 2 4,925 15 Asset-backed securities — — 1,130 39 1,130 39 Collateralized mortgage obligations - government issued 525 — 1,493 7 2,018 7 Collateralized mortgage obligations - government-sponsored enterprises 20,374 84 1,992 8 22,366 92 $ 26,415 $ 97 $ 5,024 $ 56 $ 31,439 $ 153 As of December 31, 2015 Less than 12 months 12 months or longer Total Fair value Unrealized losses Fair value Unrealized losses Fair value Unrealized losses (In Thousands) Available-for-sale: U.S. Government agency obligations - government-sponsored enterprises $ 3,536 $ 13 $ 1,981 $ 19 $ 5,517 $ 32 Municipal obligations 2,403 7 — — 2,403 7 Asset-backed securities 1,269 $ 58 — — 1,269 58 Collateralized mortgage obligations - government issued 3,373 19 5,687 97 9,060 116 Collateralized mortgage obligations - government-sponsored enterprises 59,992 373 1,717 43 61,709 416 $ 70,573 $ 470 $ 9,385 $ 159 $ 79,958 $ 629 The tables below show the Corporation’s gross unrecognized losses and fair value of held-to-maturity investments, aggregated by investment category and length of time that individual investments were in a continuous loss position at September 30, 2016 and December 31, 2015 . At September 30, 2016 , the Corporation held one held-to-maturity security that was in an unrecognized loss position. Such security has not experienced credit rating downgrades; however, it has primarily declined in value due to the current interest rate environment. There were no held-to-maturity securities that were in a continuous unrecognized loss position for twelve months or greater as of September 30, 2016 . It is expected that the Corporation will recover the entire amortized cost basis of each held-to-maturity security based upon an evaluation of the present value of the expected future cash flows. Accordingly, no other-than-temporary impairment was recorded in the Consolidated Statements of Income for the nine months ended September 30, 2016 and 2015 .

Receivables [Abstract]
Loan and Lease Receivables, Impaired Loans and Leases and Allowance for Loan and Lease Losses	Loan and Lease Receivables, Impaired Loans and Leases and Allowance for Loan and Lease Losses Loan and lease receivables consist of the following: September 30, December 31, (In Thousands) Commercial real estate Commercial real estate — owner occupied $ 169,170 $ 176,322 Commercial real estate — non-owner occupied 483,540 436,901 Land development 60,348 59,779 Construction 110,426 100,625 Multi-family 73,081 80,254 1-4 family 46,341 50,304 Total commercial real estate 942,906 904,185 Commercial and industrial 464,920 472,193 Direct financing leases, net 29,638 31,093 Consumer and other Home equity and second mortgages 5,390 8,237 Other 16,610 16,319 Total consumer and other 22,000 24,556 Total gross loans and leases receivable 1,459,464 1,432,027 Less: Allowance for loan and lease losses 20,067 16,316 Deferred loan fees 1,167 1,062 Loans and leases receivable, net $ 1,438,230 $ 1,414,649 Loans transferred to third parties consist of the guaranteed portion of Small Business Administration (“SBA”) loans which the Corporation sold in the secondary market, as well as participation interests in other originated loans. The total principal amount of the guaranteed portion of SBA loans sold during the three months ended September 30, 2016 and 2015 was $3.3 million and $9.1 million , respectively. For the nine months ended September 30, 2016 and 2015 , $34.3 million and $19.2 million of the guaranteed portion of SBA loans were sold to third parties, respectively. Each of the transfers of these financial assets met the qualifications for sale accounting, and therefore all of the loans transferred during the nine months ended September 30, 2016 and 2015 have been derecognized in the unaudited Consolidated Financial Statements. The Corporation has a continuing involvement in each of the transferred lending arrangements by way of relationship management, servicing the loans, as well as being subject to normal and customary requirements of the SBA loan program; however, there are no further obligations to the third-party participant required of the Corporation, other than standard representations and warranties related to sold amounts, that would preclude the application of sale accounting treatment. The guaranteed portion of SBA loans were transferred at their fair value and the related gain was recognized upon the transfer as non-interest income in the unaudited Consolidated Financial Statements. The total outstanding balance of sold SBA loans at September 30, 2016 and December 31, 2015 was $96.9 million and $73.4 million , respectively. In the event of a loss resulting from default and the SBA determines there is a deficiency in the manner in which the loan was originated, funded or serviced by the Corporation, the SBA may require the Corporation to repurchase the loan, deny its liability under the guaranty, reduce the amount of the guaranty, or, if it has already paid under the guaranty, seek recovery of the principal loss related to the deficiency from the Corporation. The Corporation must comply with applicable SBA regulations in order to maintain the guaranty. In addition, the Corporation retains the option to repurchase the sold guaranteed portion of an SBA loan if the loan defaults. Management has assessed estimated losses inherent in the outstanding guaranteed portion of SBA loans sold in accordance with ASC 450, Contingencies , and determined a reserve based on the probability of future losses for these loans to be $375,000 at September 30, 2016, which is reported in other liabilities on the Corporation’s Consolidated Balance Sheets. No recourse reserve was recorded as of December 31, 2015. To date, the Corporation has not experienced significant historical losses related to the guaranteed portion of SBA loans. As of September 30, 2016 and December 31, 2015 , the total amount of the Corporation’s partial ownership of sold SBA loans on the Corporation’s Consolidated Balance Sheets was $30.0 million and $24.6 million , respectively. As of September 30, 2016 , $2.3 million of loans in this portfolio were considered impaired as compared to $1.8 million as of December 31, 2015 . The total principal amount of transferred participation interests in other originated loans during the three months ended September 30, 2016 and 2015 was $16.7 million and $18.3 million , respectively. For the nine months ended September 30, 2016 and 2015 , $32.1 million and $54.8 million of these participation interests were transferred to third parties, respectively, all of which were treated as sales and derecognized under the applicable accounting guidance at the time of transfer. No gain or loss was recognized on participation interests in other originated loans as they were transferred at or near the date of loan origination and the payments received for servicing the portion of the loans participated represents adequate compensation. The total outstanding balance of transferred loans at September 30, 2016 and December 31, 2015 was $109.1 million and $95.8 million , respectively. As of September 30, 2016 and December 31, 2015 , the total amount of the Corporation’s partial ownership of these transferred loans on the Corporation’s Consolidated Balance Sheets was $109.3 million and $112.2 million , respectively. No loans in this participation portfolio were considered impaired as of September 30, 2016 and December 31, 2015 . The Corporation does not share in the participant’s portion of any potential charge-offs. The total amount of loan participations purchased on the Corporation’s Consolidated Balance Sheets as of September 30, 2016 and December 31, 2015 was $454,000 and $467,000 , respectively. According to ASC 310-30, Accounting for Certain Loans or Debt Securities Acquired in a Transfer , purchased credit-impaired loans exhibit evidence of deterioration in credit quality since origination for which it is probable at acquisition that the Corporation will be unable to collect all contractually required payments. Purchased credit-impaired loans are initially recorded at fair value, which is estimated by discounting the cash flows expected to be collected at the acquisition date. Because the estimate of expected cash flows reflects an estimate of future credit losses expected to be incurred over the life of the loans, an allowance for credit losses is not recorded at the acquisition date. The excess of cash flows expected at acquisition over the estimated fair value, referred to as the accretable yield, is recognized in interest income over the remaining life of the loan on a level-yield basis, contingent on the subsequent evaluation of future expected cash flows. The difference between the contractually required payments at acquisition and the cash flows expected to be collected at acquisition is referred to as the nonaccretable difference. A subsequent decrease in the estimate of cash flows expected to be received on purchased credit-impaired loans generally results in the recognition of an allowance for loan and lease losses. Subsequent increases in cash flows result in reversal of any nonaccretable difference (or allowance for loan and lease losses to the extent any has been recorded) with a positive impact on interest income recognized. The measurement of cash flows involves assumptions and judgments for interest rates, prepayments, default rates, loss severity and collateral values. All of these factors are inherently subjective and significant changes in the cash flow estimates over the life of the loan can result. The following table reflects the contractually required payments receivable and fair value of the Corporation’s purchased credit-impaired loans as of September 30, 2016 and December 31, 2015 : September 30, December 31, (In Thousands) Contractually required payments $ 3,806 $ 5,291 Fair value of purchased credit-impaired loans 1,937 3,250 The following table presents a rollforward of the Corporation’s accretable yield as of September 30, 2016 and December 31, 2015 : As of and for the Nine Months Ended September 30, 2016 As of and for Year Ended December 31, 2015 (In Thousands) Accretable yield, beginning of period $ 414 $ 676 Accretion recognized in earnings (100 ) (50 ) Reclassification to nonaccretable difference for loans with changing cash flows (1) (216 ) (60 ) Changes in accretable yield for non-credit related changes in expected cash flows (2) 73 (152 ) Accretable yield, end of period $ 171 $ 414 (1) Represents changes in accretable yield for those loans that are driven primarily by credit performance.

The following information illustrates ending balances of the Corporation’s loan and lease portfolio, including impaired loans by class of receivable, and considering certain credit quality indicators as of September 30, 2016 and December 31, 2015 : Category As of September 30, 2016 I II III IV Total (Dollars in Thousands) Commercial real estate: Commercial real estate — owner occupied $ 139,894 $ 13,205 $ 11,468 $ 4,603 $ 169,170 Commercial real estate — non-owner occupied 460,093 19,035 2,505 1,907 483,540 Land development 54,194 833 1,647 3,674 60,348 Construction 99,947 5,470 2,056 2,953 110,426 Multi-family 72,856 225 — — 73,081 1-4 family 39,605 2,632 1,339 2,765 46,341 Total commercial real estate 866,589 41,400 19,015 15,902 942,906 Commercial and industrial 370,580 40,619 43,752 9,969 464,920 Direct financing leases, net 28,733 591 314 — 29,638 Consumer and other: Home equity and second mortgages 4,637 557 14 182 5,390 Other 16,132 82 5 391 16,610 Total consumer and other 20,769 639 19 573 22,000 Total gross loans and leases receivable $ 1,286,671 $ 83,249 $ 63,100 $ 26,444 $ 1,459,464 Category as a % of total portfolio 88.17 % 5.70 % 4.32 % 1.81 % 100.00 % Category As of December 31, 2015 I II III IV Total (Dollars in Thousands) Commercial real estate: Commercial real estate — owner occupied $ 156,379 $ 7,654 $ 9,311 $ 2,978 $ 176,322 Commercial real estate — non-owner occupied 410,517 20,662 3,408 2,314 436,901 Land development 52,817 2,241 309 4,412 59,779 Construction 98,693 851 564 517 100,625 Multi-family 79,368 884 — 2 80,254 1-4 family 41,086 3,985 1,865 3,368 50,304 Total commercial real estate 838,860 36,277 15,457 13,591 904,185 Commercial and industrial 430,199 7,139 25,706 9,149 472,193 Direct financing leases, net 29,514 1,013 528 38 31,093 Consumer and other: Home equity and second mortgages 7,497 — 141 599 8,237 Other 15,616 48 — 655 16,319 Total consumer and other 23,113 48 141 1,254 24,556 Total gross loans and leases receivable $ 1,321,686 $ 44,477 $ 41,832 $ 24,032 $ 1,432,027 Category as a % of total portfolio 92.29 % 3.11 % 2.92 % 1.68 % 100.00 % Credit underwriting through a committee process is a key component of the Corporation’s operating philosophy. Commercial lenders have relatively low individual lending authority limits, and thus a significant portion of the Corporation’s new credit extensions require approval from a loan approval committee regardless of the type of loan or lease, asset quality grade of the credit, amount of the credit or the related complexities of each proposal. Each credit is evaluated for proper risk rating upon origination, at the time of each subsequent renewal, upon receipt and evaluation of updated financial information from the Corporation’s borrowers or as other circumstances dictate. The Corporation uses a nine grade risk rating system to monitor the ongoing credit quality of its loans and leases. The risk rating grades follow a consistent definition and are then applied to specific loan types based on the nature of the loan. Each risk rating is subjective and, depending on the size and nature of the credit, subject to various levels of review and concurrence on the stated risk rating. In addition to its nine grade risk rating system, the Corporation groups loans into four loan and related risk categories which determine the level and nature of review by management. Category I — Loans and leases in this category are performing in accordance with the terms of the contract and generally exhibit no immediate concerns regarding the security and viability of the underlying collateral, financial stability of the borrower, integrity or strength of the borrower’s management team or the industry in which the borrower operates. Loans and leases in this category are not subject to additional monitoring procedures above and beyond what is required at the origination or renewal of the loan or lease. The Corporation monitors Category I loans and leases through payment performance, continued maintenance of its personal relationships with such borrowers and continued review of such borrowers’ compliance with the terms of their respective agreements. Category II — Loans and leases in this category are beginning to show signs of deterioration in one or more of the Corporation’s core underwriting criteria such as financial stability, management strength, industry trends and collateral values. Management will place credits in this category to allow for proactive monitoring and resolution with the borrower to possibly mitigate the area of concern and prevent further deterioration or risk of loss to the Corporation. Category II loans are considered performing but are monitored frequently by the assigned business development officer and by subcommittees of the Banks’ loan committees. Category III — Loans and leases in this category are identified by management as warranting special attention. However, the balance in this category is not intended to represent the amount of adversely classified assets held by the Banks. Category III loans and leases generally exhibit undesirable characteristics, such as evidence of adverse financial trends and conditions, managerial problems, deteriorating economic conditions within the related industry or evidence of adverse public filings and may exhibit collateral shortfall positions. Management continues to believe that it will collect all contractual principal and interest in accordance with the original terms of the contracts relating to the loans and leases in this category, and therefore Category III loans are considered performing with no specific reserves established for this category. Category III loans are monitored by management and loan committees of the Banks on a monthly basis and the Banks’ Boards of Directors at each of their regularly scheduled meetings. Category IV — Loans and leases in this category are considered to be impaired. Impaired loans and leases have been placed on non-accrual as management has determined that it is unlikely that the Banks will receive the contractual principal and interest in accordance with the contractual terms of the agreement. Impaired loans are individually evaluated to assess the need for the establishment of specific reserves or charge-offs. When analyzing the adequacy of collateral, the Corporation obtains external appraisals at least annually for impaired loans and leases. External appraisals are obtained from the Corporation’s approved appraiser listing and are independently reviewed to monitor the quality of such appraisals. To the extent a collateral shortfall position is present, a specific reserve or charge-off will be recorded to reflect the magnitude of the impairment. Loans and leases in this category are monitored by management and loan committees of the Banks on a monthly basis and the Banks’ Boards of Directors at each of their regularly scheduled meetings. Utilizing regulatory classification terminology, the Corporation identified $32.1 million and $26.8 million of loans and leases as Substandard as of September 30, 2016 and December 31, 2015 , respectively.

The difference between the loans and leases recorded investment and the unpaid principal balance of $3.4 million and $3.9 million as of September 30, 2016 and December 31, 2015 , respectively, represents partial charge-offs resulting from losses due to the appraised value of the collateral securing the loans and leases being below the carrying values of the loans and leases. Impaired loans and leases also included $732,000 and $1.7 million of loans as of September 30, 2016 and December 31, 2015 that were performing troubled debt restructurings, and thus, although not on non-accrual, were reported as impaired due to the concession in terms. When a loan is placed on non-accrual, interest accrual is discontinued and previously accrued but uncollected interest is deducted from interest income. Cash payments collected on non-accrual loans are first applied to such loan’s principal. Foregone interest represents the interest that was contractually due on the loan but not received or recorded. To the extent the amount of principal on a non-accrual loan is fully collected and additional cash is received, the Corporation will recognize interest income. To determine the level and composition of the allowance for loan and lease losses, the Corporation categorizes the portfolio by segments and risk ratings. First, the Corporation evaluates loans and leases for potential impairment classification. The Corporation analyzes each loan and lease determined to be impaired on an individual basis to determine a specific reserve based upon the estimated value of the underlying collateral for collateral-dependent loans, or alternatively, the present value of expected cash flows. The Corporation applies historical trends from established risk factors to each category of loans and leases that has not been individually evaluated for the purpose of establishing the general portion of the allowance. A summary of the activity in the allowance for loan and lease losses by portfolio segment is as follows: As of and for the Nine Months Ended September 30, 2016 Commercial Real Estate Commercial and Industrial Consumer and Other Total (Dollars in Thousands) Allowance for loan and lease losses: Beginning balance $ 11,220 $ 4,387 $ 709 $ 16,316 Charge-offs (1,194 ) (2,048 ) (8 ) (3,250 ) Recoveries 170 2 5 177 Provision 2,619 4,331 (126 ) 6,824 Ending balance $ 12,815 $ 6,672 $ 580 $ 20,067 Ending balance: individually evaluated for impairment $ 1,385 $ 3,251 $ — $ 4,636 Ending balance: collectively evaluated for impairment $ 11,430 $ 3,421 $ 580 $ 15,431 Ending balance: loans acquired with deteriorated credit quality $ — $ — $ — $ — Loans and lease receivables: Ending balance, gross $ 942,906 $ 494,558 $ 22,000 $ 1,459,464 Ending balance: individually evaluated for impairment $ 13,953 $ 9,946 $ 413 $ 24,312 Ending balance: collectively evaluated for impairment $ 927,017 $ 484,589 $ 21,414 $ 1,433,020 Ending balance: loans acquired with deteriorated credit quality $ 1,936 $ 23 $ 173 $ 2,132 Allowance as % of gross loans and leases 1.36 % 1.35 % 2.64 % 1.37 % As of and for Year Ended December 31, 2015 Commercial Real Estate Commercial and Industrial Consumer and Other Total (Dollars in Thousands) Allowance for loan and lease losses: Beginning balance $ 8,619 $ 5,492 $ 218 $ 14,329 Charge-offs (793 ) (711 ) (9 ) (1,513 ) Recoveries 104 6 4 114 Provision 3,290 (400 ) 496 3,386 Ending balance $ 11,220 $ 4,387 $ 709 $ 16,316 Ending balance: individually evaluated for impairment $ 240 $ 847 $ 26 $ 1,113 Ending balance: collectively evaluated for impairment $ 10,980 $ 3,540 $ 683 $ 15,203 Ending balance: loans acquired with deteriorated credit quality $ — $ — $ — $ — Loans and lease receivables: Ending balance, gross $ 904,185 $ 503,286 $ 24,556 $ 1,432,027 Ending balance: individually evaluated for impairment $ 10,849 $ 8,942 $ 1,061 $ 20,852 Ending balance: collectively evaluated for impairment $ 890,594 $ 494,098 $ 23,495 $ 1,408,187 Ending balance: loans acquired with deteriorated credit quality $ 2,742 $ 246 $ 193 $ 3,181 Allowance as % of gross loans and leases 1.24 % 0.87 % 2.89 % 1.14 %

Other Assets	Note 6 — Other Assets The Corporation is a limited partner in several limited partnership investments. The Corporation is not the general partner, does not have controlling ownership and is not the primary beneficiary in any of these limited partnerships and thus, the variable interest entities have not been consolidated. These investments are accounted for using the equity method of accounting and are evaluated for impairment at the end of each reporting period. For historic rehabilitation tax credits, the Corporation begins to evaluate its investments for impairment at the time the credit is earned, which is typically in the year the project is placed in service, through the end of its compliance period. New market tax credits are also evaluated for impairment beginning at the time the tax credits are earned on the project through the seven year compliance period. Historic Rehabilitation Tax Credits In 2015, the Corporation invested in a development entity through BOC Investment, LLC (“BOC”), a wholly-owned subsidiary of FBB, to acquire, rehabilitate and operate a historic building in Madison, Wisconsin. At September 30, 2016 and December 31, 2015 the net carrying value of the investment was 169,000 and 578,000 , respectively. During the third quarter of 2016 , the Corporation recognized $3.6 million in historic tax credits related to this investment and $3.2 million in impairment of the underlying investment. In 2016, the Corporation also invested in a development entity through Mitchell Street Apartments Investment, LLC (“Mitchell Street”), a wholly-owned subsidiary of FBB, to rehabilitate a historic building in Milwaukee, Wisconsin. At September 30, 2016 , the net carrying value of the investment was $130,000 . The aggregate capital contributions to the project will depend upon the final amount of the certified project costs, but are expected to approximate $5.5 million . The Corporation is also anticipating the sale of a portion of the state credits associated with the investment to a third party. No historic tax credits were received in 2016 and will be used in the year the project is placed in service and are subject to a five year recapture period. New Market Tax Credits The Corporation invested in a community development entity (“CDE”) through Rimrock Road Investment Fund LLC (“Rimrock”), a wholly-owned subsidiary of FBB, to develop and operate a real estate project located in a low-income community. At September 30, 2016 and December 31, 2015 , Rimrock had one CDE investment with a net carrying value of $7.2 million and $7.5 million respectively. The investment provides federal new market tax credits over a seven-year credit allowance period through 2020. The remaining federal new market tax credit to be utilized over a maximum of seven years was $1.9 million as of September 30, 2016 . The Corporation’s usage of the federal new market tax credit was approximately $281,000 during both the nine months ended September 30, 2016 and 2015 . Other Investments The Corporation had an equity investment in Aldine Capital Fund, LP, a mezzanine fund, of $857,000 and $1.0 million recorded as of September 30, 2016 and December 31, 2015 , respectively. The Corporation’s equity investment in Aldine Capital Fund II, LP, also a mezzanine fund, totaled $3.0 million and $2.2 million as of September 30, 2016 and December 31, 2015 , respectively. The Corporation’s share of these partnerships’ income included in the unaudited Consolidated Statements of Income for the nine months ended September 30, 2016 and 2015 was $708,000 and $460,000 , respectively.

Fair Value Disclosures [Abstract]
Fair Value Disclosures	Fair Value Disclosures The Corporation determines the fair values of its financial instruments based on the fair value hierarchy established in ASC Topic 820, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Fair value is defined as the price that would be received in an orderly transaction that is not a forced liquidation or distressed sale at the measurement date and is based on exit prices. Fair value includes assumptions about risk, such as nonperformance risk in liability fair values, and is a market-based measurement, not an entity-specific measurement. The standard describes three levels of inputs that may be used to measure fair value. Level 1 — Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Corporation has the ability to access at the measurement date. Level 2 — Level 2 inputs are inputs, other than quoted prices included with Level 1, that are observable for the asset or liability either directly or indirectly, 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 for substantially the full term of the assets or liabilities. Level 3 — Level 3 inputs are supported by little or no market activity and are significant to the fair value of the assets or liabilities. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Corporation’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. Assets and liabilities measured at fair value on a recurring basis, segregated by fair value hierarchy level, are summarized below: Fair Value Measurements Using September 30, 2016 Level 1 Level 2 Level 3 Total (In Thousands) Assets: Securities available-for-sale: Municipal obligations $ — $ 8,277 $ — $ 8,277 Asset backed securities — 1,130 — 1,130 U.S. Government agency obligations - government-sponsored enterprises — 6,337 — 6,337 Collateralized mortgage obligations - government issued — 31,282 — 31,282 Collateralized mortgage obligations - government-sponsored enterprises — 107,454 — 107,454 Interest rate swaps — 1,014 — 1,014 Liabilities: Interest rate swaps $ — $ 1,014 $ — $ 1,014 Fair Value Measurements Using December 31, 2015 Level 1 Level 2 Level 3 Total (In Thousands) Assets: Securities available-for-sale: Municipal obligations $ — $ 4,283 $ — $ 4,283 Asset backed securities — 1,269 — 1,269 U.S. Government agency obligations - government-sponsored enterprises — 8,017 — 8,017 Collateralized mortgage obligations - government issued — 44,543 — 44,543 Collateralized mortgage obligations - government-sponsored enterprises — 82,436 — 82,436 Interest rate swaps — 552 — 552 Liabilities: Interest rate swaps $ — $ 552 $ — $ 552 For assets and liabilities measured at fair value on a recurring basis, there were no transfers between the levels during the nine months ended September 30, 2016 or the year ended December 31, 2015 related to the above measurements. Assets and liabilities measured at fair value on a non-recurring basis, segregated by fair value hierarchy are summarized below: Balance at Fair Value Measurements Using Total Gains (Losses) September 30, Level 1 Level 2 Level 3 (In Thousands) Impaired loans $ 14,623 $ — $ 13,627 $ 996 $ — Foreclosed properties 1,527 — 1,527 — (23 ) Loan servicing rights 1,879 — — 1,879 — Balance at Fair Value Measurements Using Total Gains (Losses) December 31, Level 1 Level 2 Level 3 (In Thousands) Impaired loans $ 17,763 $ — $ 11,518 $ 6,245 $ — Foreclosed properties 1,677 — 1,677 — (36 ) Loan servicing rights 1,563 — — 1,563 — Impaired loans were written down to the fair value of their underlying collateral less costs to sell of $14.6 million and $17.8 million at September 30, 2016 and December 31, 2015 , respectively, through the establishment of specific reserves or by recording charge-offs when the carrying value exceeded the fair value of the underlying collateral of impaired loans. Valuation techniques consistent with the market approach, income approach or cost approach were used to measure fair value and primarily included observable inputs for the individual impaired loans being evaluated such as current appraisals, recent sales of similar assets or other observable market data, and are reflected within Level 2 of the hierarchy. In cases where an input is unobservable, specifically when discounts are applied to appraisal values to adjust such values to current market conditions or to reflect net realizable value, the impaired loan balance is reflected within Level 3 of the hierarchy. The quantification of unobservable inputs for Level 3 impaired loan values range from 15% - 93% . The weighted average of those unobservable inputs as of the measurement date of September 30, 2016 was 48% . The majority of the impaired loans in the Level 3 category are considered collateral dependent loans. Loan servicing rights represent the asset retained upon sale of the guaranteed portion of certain SBA loans. When SBA loans are sold, servicing rights are initially recorded at fair value with the income statement effect recorded in gains on sales of loans. The servicing rights are subsequently measured using the amortization method, which requires amortization into non-interest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans. The Corporation periodically reviews this portfolio for impairment and engages a third-party valuation firm to assess the fair value of the overall servicing rights portfolio. Loan servicing rights do not trade in an active, open market with readily observable prices. While sales of loan servicing rights do occur, the precise terms and conditions typically are not readily available to allow for a “quoted price for similar assets” comparison. Accordingly, the Corporation utilizes an independent valuation from a third party which uses a discounted cash flow model to estimate the fair value of its loan servicing rights. The valuation model incorporates prepayment assumptions to project loan servicing rights cash flows based on the current interest rate scenario, which is then discounted to estimate an expected fair value of the loan servicing rights. The valuation model considers portfolio characteristics of the underlying serviced portion of the SBA loans and uses the following significant unobservable inputs: (1) constant prepayment rate (“CPR”) assumptions based on the SBA sold pools historical CPR as quoted in Bloomberg and (2) a discount rate of 10%. Due to the nature of the valuation inputs, loan servicing rights are classified in Level 3 of the fair value hierarchy. As of September 30, 2016 and December 31, 2015 , the estimated fair value of the Corporation’s loan servicing asset was $1.9 million and $1.6 million , respectively. Foreclosed properties, upon initial recognition, are re-measured and reported at fair value through a charge-off to the allowance for loan and lease losses, if deemed necessary, based upon the fair value of the foreclosed property. The fair value of a foreclosed property, upon initial recognition, is estimated using a market approach or Level 2 inputs based on observable market data, typically a current appraisal, or Level 3 inputs based upon assumptions specific to the individual property or equipment. Level 3 inputs typically include unobservable inputs such as management-applied discounts used to further reduce values to a net realizable value and may be used in situations when observable inputs become stale. Foreclosed property fair value inputs may transition to Level 1 upon receipt of an accepted offer for the sale of the related foreclosed property. As of September 30, 2016 and December 31, 2015 , there were no foreclosed properties supported by a Level 3 valuation. Subsequent impairments of foreclosed properties are recorded as a loss on foreclosed properties. For the nine months ended September 30, 2016 , $23,000 of subsequent impairment losses were recognized. Fair Value of Financial Instruments The Corporation is required to disclose estimated fair values for its financial instruments. Fair value estimates, methods and assumptions, consistent with exit price concepts for fair value measurements, are set forth below: September 30, 2016 Carrying Amount Fair Value Total Level 1 Level 2 Level 3 (In Thousands) Financial assets: Cash and cash equivalents $ 68,764 $ 68,771 $ 48,689 $ 4,457 $ 15,625 Securities available-for-sale 154,480 154,480 — 154,480 — Securities held-to-maturity 35,109 35,964 — 35,964 — Loans held for sale 2,627 2,627 — 2,627 — Loans and lease receivables, net 1,438,230 1,475,215 — 13,627 1,461,588 Federal Home Loan Bank and Federal Reserve Bank stock 2,165 2,165 — — 2,165 Bank-owned life insurance 29,028 29,028 29,028 — — Accrued interest receivable 4,448 4,448 4,448 — — Interest rate swaps 1,014 1,014 — 1,014 — Financial liabilities: Deposits $ 1,566,199 $ 1,573,273 $ 1,054,776 $ 518,497 $ — Federal Home Loan Bank and other borrowings 29,946 30,844 — 30,844 — Junior subordinated notes 10,001 6,534 — — 6,534 Interest rate swaps 1,014 1,014 — 1,014 — Accrued interest payable 1,930 1,930 1,930 — — Off-balance-sheet items: Standby letters of credit 50 50 — — 50 December 31, 2015 Carrying Amount Fair Value Total Level 1 Level 2 Level 3 (In Thousands) Financial assets: Cash and cash equivalents $ 113,564 $ 113,564 $ 100,063 $ 4,451 $ 9,050 Securities available-for-sale 140,548 140,548 — 140,548 — Securities held-to-maturity 37,282 37,558 — 37,558 — Loans held for sale 2,702 2,702 — 2,702 — Loans and lease receivables, net 1,414,649 1,445,773 — 11,518 1,434,255 Federal Home Loan Bank and Federal Reserve Bank stock 2,843 2,843 — — 2,843 Cash surrender value of life insurance 28,298 28,298 28,298 — — Accrued interest receivable 4,412 4,412 4,412 — — Interest rate swaps 552 552 — 552 — Financial liabilities: Deposits $ 1,577,231 $ 1,577,838 $ 1,009,762 $ 568,076 $ — Federal Home Loan Bank and other borrowings 34,740 35,353 — 35,353 — Junior subordinated notes 9,990 6,614 — — 6,614 Interest rate swaps 552 552 — 552 — Accrued interest payable 1,766 1,766 1,766 — — Off-balance-sheet items: Standby letters of credit 183 183 — — 183 Disclosure of fair value information about financial instruments, for which it is practicable to estimate that value, is required whether or not recognized in the Consolidated Balance Sheets. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, could not be realized in immediate settlement of the instruments. Certain financial instruments and all non-financial instruments are excluded from the disclosure requirements. Accordingly, the aggregate fair value amounts presented do not necessarily represent the underlying value of the Corporation. Cash and Cash Equivalents: The carrying amounts reported for cash and due from banks, interest-bearing deposits held by the Corporation, accrued interest receivable and accrued interest payable approximate fair value because of their immediate availability and because they do not present unanticipated credit concerns. As of September 30, 2016 and December 31, 2015 , the Corporation held $15.6 million and $9.1 million , respectively, of commercial paper. The fair value of commercial paper is classified as a Level 3 input due to the lack of available independent pricing sources. The carrying value of brokered certificates of deposit purchased is equivalent to the purchase price of the instruments as the Corporation has not elected a fair value option for these instruments. The fair value of brokered certificates of deposits purchased is based on the discounted value of contractual cash flows using a discount rate reflective of rates currently offered for deposits of similar remaining maturities. As of both September 30, 2016 and December 31, 2015 , the Corporation held $4.5 million of brokered certificates of deposits. Securities: The fair value measurements of investment securities are determined by a third-party pricing service which considers observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, trade execution data, market consensus prepayment speeds, credit information and the securities’ terms and conditions, among other things. The fair value measurements are subject to independent verification to another pricing source on a quarterly basis to review for reasonableness. Any significant differences in pricing are reviewed with appropriate members of management who have the relevant technical expertise to assess the results. The Corporation has determined that these valuations are classified in Level 2 of the fair value hierarchy. When the independent pricing service does not provide a fair value measurement for a particular security, the Corporation will estimate the fair value based on specific information about each security. Fair values derived in this manner are classified in Level 3 of the fair value hierarchy. Loans Held for Sale: Loans held for sale, which consist of residential real estate mortgage loans and the guaranteed portion of SBA loans, are carried at the lower of cost or estimated fair value. The estimated fair value was based on what secondary markets are currently offering for portfolios with similar characteristics. Loans and Lease Receivables, net: The fair value estimation process for the loan portfolio uses an exit price concept and reflects discounts that the Corporation believes are consistent with liquidity discounts in the market place. Fair values are estimated for portfolios of loans with similar financial characteristics. The fair value of performing and nonperforming loans is calculated by discounting scheduled and expected cash flows through the estimated maturity using estimated market rates that reflect the credit and interest rate risk inherent in the portfolio of loans and then applying a discount factor based upon the embedded credit risk of the loan and the fair value of collateral securing nonperforming loans when the loan is collateral dependent. The estimate of maturity is based on the Banks’ historical experience with repayments for each loan classification, modified, as required, by an estimate of the effect of current economic and lending conditions. Significant unobservable inputs include, but are not limited to, discounts (investor yield premiums) applied to fair value calculations to further determine the exit price value of a portfolio of loans. Federal Home Loan Bank and Federal Reserve Bank Stock: The carrying amount of FHLB and FRB stock equals its fair value because the shares may be redeemed by the FHLB and the FRB at their carrying amount of $100 per share. Bank-owned Life Insurance: The carrying amount of the cash surrender value of life insurance approximates its fair value as the carrying value represents the current settlement amount. Deposits: The fair value of deposits with no stated maturity, such as demand deposits and money market accounts, is equal to the amount payable on demand. The fair value of time deposits is based on the discounted value of contractual cash flows. The discount rate is estimated using the rates currently offered for deposits of similar remaining maturities. The fair value estimates do not include the intangible value that results from the funding provided by deposit liabilities compared to borrowing funds in the market. Borrowed Funds: Market rates currently available to the Corporation and Banks for debt with similar terms and remaining maturities are used to estimate fair value of existing debt. Interest Rate Swaps: The carrying amount and fair value of existing derivative financial instruments are based upon independent valuation models, which use widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative contract. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The Corporation incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Corporation considers the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts and guarantees. Financial Instruments with Off-Balance-Sheet Risks: The fair value of the Corporation’s off-balance-sheet instruments is based on quoted market prices and fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the credit standing of the related counterparty. Commitments to extend credit and standby letters of credit are generally not marketable. Furthermore, interest rates on any amounts drawn under such commitments would generally be established at market rates at the time of the draw. Fair value would principally derive from the present value of fees received for those products. Limitations: Fair value estimates are made at a discrete point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Corporation’s entire holding of a particular financial instrument. Because no market exists for a significant portion of the Corporation’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Fair value estimates are based on existing balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and are not considered in the estimates.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments The Corporation offers interest rate swap products directly to qualified commercial borrowers. The Corporation economically hedges client derivative transactions by entering into offsetting interest rate swap contracts executed with a third party. Derivative transactions executed as part of this program are not designated as accounting hedge relationships and are marked to market through earnings each period. The derivative contracts have mirror-image terms, which results in the positions’ changes in fair value primarily offsetting through earnings each period. The credit risk and risk of non-performance embedded in the fair value calculations is different between the dealer counterparties and the commercial borrowers, which may result in a difference in the changes in the fair value of the mirror-image swaps. The Corporation incorporates credit valuation adjustments to appropriately reflect both its own non-performance risk and the counterparty’s risk in the fair value measurements. When evaluating the fair value of its derivative contracts for the effects of non-performance and credit risk, the Corporation considers the impact of netting and any applicable credit enhancements such as collateral postings, thresholds and guarantees. At September 30, 2016 , the aggregate amortizing notional value of interest rate swaps with various commercial borrowers was $20.0 million . The Corporation receives fixed rates and pays floating rates based upon LIBOR on the swaps with commercial borrowers. These interest rate swaps mature in August, 2018 through February, 2023 . Commercial borrower swaps are completed independently with each borrower and are not subject to master netting arrangements. These commercial borrower swaps were reported on the unaudited Consolidated Balance Sheets as a derivative asset of $1.0 million and are included in accrued interest receivable and other assets. In the event of default on a commercial borrower interest rate swap by the counterparty, a right of offset exists to allow the commercial borrower to set off amounts due against the related commercial loan. As of September 30, 2016 , no interest rate swaps were in default and therefore all values for the commercial borrower swaps are recorded on a gross basis within the Corporation’s financial position. At September 30, 2016 , the aggregate amortizing notional value of interest rate swaps with dealer counterparties was also $20.0 million . The Corporation pays fixed rates and receives floating rates based upon LIBOR on the swaps with dealer counterparties. These interest rate swaps mature in August, 2018 through February, 2023 . Dealer counterparty swaps are subject to master netting agreements among the contracts within each of the Banks and are reported on the unaudited Consolidated Balance Sheets as a net derivative liability of $1.0 million , included in accrued interest payable and other liabilities as of September 30, 2016 . The gross amount of dealer counterparty swaps was also $1.0 million as no right of offset existed with the dealer counterparty swaps as of September 30, 2016 . The table below provides information about the location and fair value of the Corporation’s derivative instruments as of September 30, 2016 and December 31, 2015 .

All changes in the fair value of these instruments are recorded in other non-interest income . Given the mirror-image terms of the outstanding derivative portfolio, the change in fair value for the nine months ended September 30, 2016 and 2015 had an insignificant impact on the unaudited Consolidated Statements of Income.

Regulatory Capital

Regulatory Capital Requirements [Abstract]
Regulatory Capital	Regulatory Capital The Corporation and the Banks are subject to various regulatory capital requirements administered by Federal, State of Wisconsin and State of Kansas banking agencies. Failure to meet minimum capital requirements can result in certain mandatory, and possibly additional discretionary actions on the part of regulators, that if undertaken, could have a direct material effect on the Banks’ assets, liabilities and certain off-balance-sheet items as calculated under regulatory practices. The Corporation’s and the Banks’ capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. The Corporation regularly reviews and updates when appropriate its Capital and Liquidity Action Plan (the “Capital Plan”), which is designed to help ensure appropriate capital adequacy, to plan for future capital needs and to ensure that the Corporation serves as a source of financial strength to the Banks. The Corporation’s and the Banks’ Boards of Directors and management teams adhere to the appropriate regulatory guidelines on decisions which affect their respective capital positions, including but not limited to, decisions relating to the payment of dividends and increasing indebtedness. As a bank holding company, the Corporation’s ability to pay dividends is affected by the policies and enforcement powers of the Board of Governors of the Federal Reserve system (the “Federal Reserve”). Federal Reserve guidance urges companies to strongly consider eliminating, deferring or significantly reducing dividends if: (i) net income available to common shareholders for the past four quarters, net of dividends previously paid during that period, is not sufficient to fully fund the dividend; (ii) the prospective rate of earnings retention is not consistent with the bank holding company’s capital needs and overall current prospective financial condition; or (iii) the bank holding company will not meet, or is in danger of not meeting, its minimum regulatory capital ratios. Management intends, when appropriate under regulatory guidelines, to consult with the Federal Reserve Bank of Chicago and provide it with information on the Corporation’s then-current and prospective earnings and capital position in advance of declaring any cash dividends. As a Wisconsin corporation, the Corporation is subject to the limitations of the Wisconsin Business Corporation Law, which prohibit the Corporation from paying dividends if such payment would: (i) render the Corporation unable to pay its debts as they become due in the usual course of business, or (ii) result in the Corporation’s assets being less than the sum of its total liabilities plus the amount needed to satisfy the preferential rights upon dissolution of any stockholders with preferential rights superior to those stockholders receiving the dividend. The Banks are also subject to certain legal, regulatory and other restrictions on their ability to pay dividends to the Corporation. As a bank holding company, the payment of dividends by the Banks to the Corporation is one of the sources of funds the Corporation could use to pay dividends, if any, in the future and to make other payments. Future dividend decisions by the Banks and the Corporation will continue to be subject to compliance with various legal, regulatory and other restrictions as defined from time to time. Qualitative measures established by regulation to ensure capital adequacy require the Corporation and the Banks to maintain minimum amounts and ratios of Total, Common Equity Tier 1 and Tier 1 capital to risk-weighted assets and of Tier 1 capital to adjusted total assets. These risk-based capital requirements presently address credit risk related to both recorded and off-balance-sheet commitments and obligations. Management believes, as of September 30, 2016 , that the Corporation and the Banks met all applicable capital adequacy requirements. In July 2013, the FRB and the FDIC approved the final rules implementing the Basel Committee on Banking Supervision’s (“BCBS”) capital guidelines for U.S. banks. These rules are applicable to all financial institutions that are subject to minimum capital requirements, including federal and state banks and savings and loan associations, as well as bank and savings and loan holding companies other than “small bank holding companies” (generally non-publicly traded bank holding companies with consolidated assets of less than $1 billion). Under the final rules, minimum requirements will increase for both the quantity and quality of capital held by the Corporation. The rules include a new Common Equity Tier 1 capital to risk-weighted assets minimum ratio of 4.5%, raise the minimum ratio of Tier 1 capital to risk-weighted assets from 4.0% to 6.0%, require a minimum ratio of Total Capital to risk-weighted assets of 8.0%, and require a minimum Tier 1 leverage ratio of 4.0%. The rules also permit banking organizations with less than $15 billion to retain, through a one-time election, the existing treatment for accumulated other comprehensive income, which would not affect regulatory capital. The Corporation elected to retain this treatment, which reduces the volatility of regulatory capital ratios. A new capital conservation buffer, comprised of Common Equity Tier 1 capital, is also established above the regulatory minimum capital requirements. This capital conservation buffer will be phased in beginning January 1, 2016 at 0.625% of risk-weighted assets and increase each subsequent year by an additional 0.625% until reaching its final level of 2.5% on January 1, 2019 .

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation. The accompanying unaudited Consolidated Financial Statements were prepared in accordance with GAAP and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the Corporation’s Consolidated Financial Statements and footnotes thereto included in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2015 .
Principles of Consolidation	he unaudited Consolidated Financial Statements include the accounts of the Corporation and its wholly owned subsidiaries. In accordance with the provisions of Accounting Standards Codification (“ASC”) Topic 810, the Corporation’s ownership interest in FBFS Statutory Trust II (“Trust II”) has not been consolidated into the financial statements. All significant intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Management of the Corporation is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements as well as reported amounts of revenues and expenses during the reporting period. Actual results could differ significantly from those estimates. Material estimates that could significantly change in the near-term include the value of lease residuals, property under operating leases, securities, income taxes, goodwill and the level of the allowance for loan and lease losses.
Reclassification	rtain amounts in prior periods may have been reclassified to conform to the current presentation. S
Subsequent Events	Subsequent events have been evaluated through the date of the issuance of the unaudited Consolidated Financial Statements. No significant subsequent events have occurred through this date requiring adjustment to the financial statements or disclosures. T

Earnings Per Share [Abstract]
Earnings Per Share	Earnings per common share are computed using the two-class method. Basic earnings per common share are computed by dividing net income allocated to common shares by the weighted average number of shares outstanding during the applicable period, excluding outstanding participating securities. Participating securities include unvested restricted shares. Unvested restricted shares are considered participating securities because holders of these securities receive non-forfeitable dividends, or dividend equivalents, at the same rate as holders of the Corporation’s common stock. Diluted earnings per share are computed by dividing net income allocated to common shares, adjusted for reallocation of undistributed earnings of unvested restricted shares, by the weighted average number of shares determined for the basic earnings per common share computation plus the dilutive effect of common stock equivalents using the treasury stock method.

Share-based Compensation, Option and Incentive Plans	Restricted Stock Under the Plan, the Corporation may grant restricted stock to plan participants, subject to forfeiture upon the occurrence of certain events until the dates specified in the participant’s award agreement. While restricted stock is subject to forfeiture, with the exception of restricted stock units, which do not have voting rights and are provided dividend equivalents, restricted stock participants may exercise full voting rights and will receive all dividends and other distributions paid with respect to the restricted shares. The restricted stock granted under the Plan is typically subject to a vesting period. Compensation expense is recognized over the requisite service period of generally four years for the entire award on a straight-line basis. Upon vesting of restricted share awards, the benefit of tax deductions in excess of recognized compensation expense is recognized as a financing cash flow activity. The Corporation adopted the 2012 Equity Incentive Plan (the “Plan”) during the quarter ended June 30, 2012. The Plan is administered by the Compensation Committee of the Board of Directors of the Corporation and provides for the grant of equity ownership opportunities through incentive stock options and nonqualified stock options (together, “Stock Options”), restricted stock, restricted stock units, dividend equivalent units and any other type of award permitted by the Plan. As of September 30, 2016 , 273,737 shares were available for future grants under the Plan. Shares covered by awards that expire, terminate or lapse will again be available for the grant of awards under the Plan. The Corporation may issue new shares and shares from its treasury stock for shares delivered under the Plan.

Receivables [Abstract]
Loans and Leases Receivable, Allowance for Loan Losses	To determine the level and composition of the allowance for loan and lease losses, the Corporation categorizes the portfolio by segments and risk ratings. First, the Corporation evaluates loans and leases for potential impairment classification. The Corporation analyzes each loan and lease determined to be impaired on an individual basis to determine a specific reserve based upon the estimated value of the underlying collateral for collateral-dependent loans, or alternatively, the present value of expected cash flows. The Corporation applies historical trends from established risk factors to each category of loans and leases that has not been individually evaluated for the purpose of establishing the general portion of the allowance.

Fair Value Disclosures (Policie

Fair Value Disclosures (Policies)	9 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	The Corporation determines the fair values of its financial instruments based on the fair value hierarchy established in ASC Topic 820, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Fair value is defined as the price that would be received in an orderly transaction that is not a forced liquidation or distressed sale at the measurement date and is based on exit prices. Fair value includes assumptions about risk, such as nonperformance risk in liability fair values, and is a market-based measurement, not an entity-specific measurement. The standard describes three levels of inputs that may be used to measure fair value. Level 1 — Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Corporation has the ability to access at the measurement date. Level 2 — Level 2 inputs are inputs, other than quoted prices included with Level 1, that are observable for the asset or liability either directly or indirectly, 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 for substantially the full term of the assets or liabilities. Level 3 — Level 3 inputs are supported by little or no market activity and are significant to the fair value of the assets or liabilities. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Corporation’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. Impaired loans were written down to the fair value of their underlying collateral less costs to sell of $14.6 million and $17.8 million at September 30, 2016 and December 31, 2015 , respectively, through the establishment of specific reserves or by recording charge-offs when the carrying value exceeded the fair value of the underlying collateral of impaired loans. Valuation techniques consistent with the market approach, income approach or cost approach were used to measure fair value and primarily included observable inputs for the individual impaired loans being evaluated such as current appraisals, recent sales of similar assets or other observable market data, and are reflected within Level 2 of the hierarchy. In cases where an input is unobservable, specifically when discounts are applied to appraisal values to adjust such values to current market conditions or to reflect net realizable value, the impaired loan balance is reflected within Level 3 of the hierarchy. The quantification of unobservable inputs for Level 3 impaired loan values range from 15% - 93% . The weighted average of those unobservable inputs as of the measurement date of September 30, 2016 was 48% . The majority of the impaired loans in the Level 3 category are considered collateral dependent loans. Loan servicing rights represent the asset retained upon sale of the guaranteed portion of certain SBA loans. When SBA loans are sold, servicing rights are initially recorded at fair value with the income statement effect recorded in gains on sales of loans. The servicing rights are subsequently measured using the amortization method, which requires amortization into non-interest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans. The Corporation periodically reviews this portfolio for impairment and engages a third-party valuation firm to assess the fair value of the overall servicing rights portfolio. Loan servicing rights do not trade in an active, open market with readily observable prices. While sales of loan servicing rights do occur, the precise terms and conditions typically are not readily available to allow for a “quoted price for similar assets” comparison. Accordingly, the Corporation utilizes an independent valuation from a third party which uses a discounted cash flow model to estimate the fair value of its loan servicing rights. The valuation model incorporates prepayment assumptions to project loan servicing rights cash flows based on the current interest rate scenario, which is then discounted to estimate an expected fair value of the loan servicing rights. The valuation model considers portfolio characteristics of the underlying serviced portion of the SBA loans and uses the following significant unobservable inputs: (1) constant prepayment rate (“CPR”) assumptions based on the SBA sold pools historical CPR as quoted in Bloomberg and (2) a discount rate of 10%. Due to the nature of the valuation inputs, loan servicing rights are classified in Level 3 of the fair value hierarchy. As of September 30, 2016 and December 31, 2015 , the estimated fair value of the Corporation’s loan servicing asset was $1.9 million and $1.6 million , respectively. Foreclosed properties, upon initial recognition, are re-measured and reported at fair value through a charge-off to the allowance for loan and lease losses, if deemed necessary, based upon the fair value of the foreclosed property. The fair value of a foreclosed property, upon initial recognition, is estimated using a market approach or Level 2 inputs based on observable market data, typically a current appraisal, or Level 3 inputs based upon assumptions specific to the individual property or equipment. Level 3 inputs typically include unobservable inputs such as management-applied discounts used to further reduce values to a net realizable value and may be used in situations when observable inputs become stale. Foreclosed property fair value inputs may transition to Level 1 upon receipt of an accepted offer for the sale of the related foreclosed property. As of September 30, 2016 and December 31, 2015 , there were no foreclosed properties supported by a Level 3 valuation. Subsequent impairments of foreclosed properties are recorded as a loss on foreclosed properties. For the nine months ended September 30, 2016 , $23,000 of subsequent impairment losses were recognized.
Fair Value Measurement	Disclosure of fair value information about financial instruments, for which it is practicable to estimate that value, is required whether or not recognized in the Consolidated Balance Sheets. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, could not be realized in immediate settlement of the instruments. Certain financial instruments and all non-financial instruments are excluded from the disclosure requirements. Accordingly, the aggregate fair value amounts presented do not necessarily represent the underlying value of the Corporation. Cash and Cash Equivalents: The carrying amounts reported for cash and due from banks, interest-bearing deposits held by the Corporation, accrued interest receivable and accrued interest payable approximate fair value because of their immediate availability and because they do not present unanticipated credit concerns. As of September 30, 2016 and December 31, 2015 , the Corporation held $15.6 million and $9.1 million , respectively, of commercial paper. The fair value of commercial paper is classified as a Level 3 input due to the lack of available independent pricing sources. The carrying value of brokered certificates of deposit purchased is equivalent to the purchase price of the instruments as the Corporation has not elected a fair value option for these instruments. The fair value of brokered certificates of deposits purchased is based on the discounted value of contractual cash flows using a discount rate reflective of rates currently offered for deposits of similar remaining maturities. As of both September 30, 2016 and December 31, 2015 , the Corporation held $4.5 million of brokered certificates of deposits. Securities: The fair value measurements of investment securities are determined by a third-party pricing service which considers observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, trade execution data, market consensus prepayment speeds, credit information and the securities’ terms and conditions, among other things. The fair value measurements are subject to independent verification to another pricing source on a quarterly basis to review for reasonableness. Any significant differences in pricing are reviewed with appropriate members of management who have the relevant technical expertise to assess the results. The Corporation has determined that these valuations are classified in Level 2 of the fair value hierarchy. When the independent pricing service does not provide a fair value measurement for a particular security, the Corporation will estimate the fair value based on specific information about each security. Fair values derived in this manner are classified in Level 3 of the fair value hierarchy. Loans Held for Sale: Loans held for sale, which consist of residential real estate mortgage loans and the guaranteed portion of SBA loans, are carried at the lower of cost or estimated fair value. The estimated fair value was based on what secondary markets are currently offering for portfolios with similar characteristics. Loans and Lease Receivables, net: The fair value estimation process for the loan portfolio uses an exit price concept and reflects discounts that the Corporation believes are consistent with liquidity discounts in the market place. Fair values are estimated for portfolios of loans with similar financial characteristics. The fair value of performing and nonperforming loans is calculated by discounting scheduled and expected cash flows through the estimated maturity using estimated market rates that reflect the credit and interest rate risk inherent in the portfolio of loans and then applying a discount factor based upon the embedded credit risk of the loan and the fair value of collateral securing nonperforming loans when the loan is collateral dependent. The estimate of maturity is based on the Banks’ historical experience with repayments for each loan classification, modified, as required, by an estimate of the effect of current economic and lending conditions. Significant unobservable inputs include, but are not limited to, discounts (investor yield premiums) applied to fair value calculations to further determine the exit price value of a portfolio of loans. Federal Home Loan Bank and Federal Reserve Bank Stock: The carrying amount of FHLB and FRB stock equals its fair value because the shares may be redeemed by the FHLB and the FRB at their carrying amount of $100 per share. Bank-owned Life Insurance: The carrying amount of the cash surrender value of life insurance approximates its fair value as the carrying value represents the current settlement amount. Deposits: The fair value of deposits with no stated maturity, such as demand deposits and money market accounts, is equal to the amount payable on demand. The fair value of time deposits is based on the discounted value of contractual cash flows. The discount rate is estimated using the rates currently offered for deposits of similar remaining maturities. The fair value estimates do not include the intangible value that results from the funding provided by deposit liabilities compared to borrowing funds in the market. Borrowed Funds: Market rates currently available to the Corporation and Banks for debt with similar terms and remaining maturities are used to estimate fair value of existing debt. Interest Rate Swaps: The carrying amount and fair value of existing derivative financial instruments are based upon independent valuation models, which use widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative contract. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The Corporation incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Corporation considers the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts and guarantees. Financial Instruments with Off-Balance-Sheet Risks: The fair value of the Corporation’s off-balance-sheet instruments is based on quoted market prices and fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the credit standing of the related counterparty. Commitments to extend credit and standby letters of credit are generally not marketable. Furthermore, interest rates on any amounts drawn under such commitments would generally be established at market rates at the time of the draw. Fair value would principally derive from the present value of fees received for those products. Limitations: Fair value estimates are made at a discrete point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Corporation’s entire holding of a particular financial instrument. Because no market exists for a significant portion of the Corporation’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Fair value estimates are based on existing balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and are not considered in the estimates.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	The Corporation offers interest rate swap products directly to qualified commercial borrowers. The Corporation economically hedges client derivative transactions by entering into offsetting interest rate swap contracts executed with a third party. Derivative transactions executed as part of this program are not designated as accounting hedge relationships and are marked to market through earnings each period. The derivative contracts have mirror-image terms, which results in the positions’ changes in fair value primarily offsetting through earnings each period. The credit risk and risk of non-performance embedded in the fair value calculations is different between the dealer counterparties and the commercial borrowers, which may result in a difference in the changes in the fair value of the mirror-image swaps. The Corporation incorporates credit valuation adjustments to appropriately reflect both its own non-performance risk and the counterparty’s risk in the fair value measurements. When evaluating the fair value of its derivative contracts for the effects of non-performance and credit risk, the Corporation considers the impact of netting and any applicable credit enhancements such as collateral postings, thresholds and guarantees.
