Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Significant Accounting Policies	(1) Organization and Significant Accounting Policies Organization. On July 14, 2014, the Conversion was completed and the Holding Company became the parent holding company for the Bank. A total of 4,232,000 shares of common stock were sold to depositors and the employee stock ownership plan (“ESOP”) at $10.00 per share through which the Holding Company received gross offering proceeds of approximately $42.3 million. The net proceeds received were $37.4 million after offering costs and the allocation of unearned ESOP shares. The Holding Company owns all the outstanding shares of common stock of the Bank. The Conversion was accounted for as a change in corporate form with the historic basis of the Bank’s assets, liabilities and equity unchanged as a result. In connection with the Conversion, the Holding Company implemented an ESOP, to provide eligible employees the opportunity to own the Company’s Common stock. This plan is a tax-qualified retirement plan for the benefit of all Bank employees. A total of 338,560 shares of common stock issued in the Conversion were acquired by the ESOP. The Bank through its eight full-service banking offices and two loan production offices provides a variety of retail community banking services to individuals and businesses primarily in Hillsborough, Polk, Pasco, and Orange Counties, Florida. The Bank’s deposits are insured up to the applicable limits by the Federal Deposit Insurance Corporation (“FDIC”). Our accounting and reporting policies conform to Accounting Principles Generally Accepted in the United States of America (“GAAP”) and general practices within the banking industry and are described in note 1 to the audited consolidated financial statements in our 2014 Annual Report on Form 10-K, as updated by information in this Form 10-Q. While management believes the sources utilized to arrive at the fair value estimates are reliable, different sources or methods could have yielded different fair value estimates. Such different value estimates could affect future earnings through different values being utilized for the disposition or amortization of the underlying assets and liabilities acquired. Acquisition Method of Accounting. Accounting for business combination under GAAP acquisition method prohibits “carrying over” valuation allowances, such as the allowance for loan losses. Uncertainties relating to the expected future cash flows is be reflected in the fair value measurement of the acquired loans and reflected in the purchase price. The Bank will establish loan loss allowances for the acquired loans in periods after the acquisition, but only for losses incurred on these loans due to credit deterioration after acquisition. As a result, the allowance for loan loss reflected in these statements is only that of historical Sunshine Bank. Purchased Credit-Impaired Loans. As a result of the Company’s recent acquisition, the Company individually evaluated three PCI loans. These acquired loans were recorded on the acquisition date at fair value. The Company estimates the amount and timing of expected cash flows for each individually analyzed loan. Estimated cash flows in excess of the amount paid is recorded as interest income over the remaining life of the loan. On a quarterly basis, the Company will update the amount of loan principal and interest cash flows expected to be collected, incorporating assumptions regarding default rates, loss severities, the amounts and timing of prepayments and other factors that are reflective of current market conditions. Probable decreases in expected loan principal cash flows trigger the recognition of impairment, which is then measured as the present value of the expected principal loss plus any related foregone interest cash flows discounted at the pool’s effective interest rate. Impairments that occur after the acquisition date are recognized through the allowance for loan losses. Probable and significant increases in expected cash flows would first reverse any previously recorded allowance for loan losses; any remaining increases are recognized prospectively as interest income. The impacts of (i) prepayments, (ii) changes in variable interest rates, and (iii) any other changes in the timing of expected cash flows are recognized prospectively as adjustments to interest income. Disposals of loans, which may include sales of loans, receipt of payments in full by the borrower, or foreclosure, result in removal of the loan from the PCI portfolio. Goodwill and Core Deposit Intangible Principles of Consolidation. In the opinion of management, the accompanying condensed consolidated financial statements of the Company contain all adjustments (consisting principally of normal recurring accruals) necessary to present fairly the financial position at September 30, 2015, and the results of operations for the three and nine month periods ended September 30, 2015 and 2014. The results of operations for the nine months ended September 30, 2015, are not necessarily indicative of the results to be expected for the full year or any other period.

Business Combinations [Abstract]
Business Combinations	(2) Business Combinations Agreement to Acquire First Federal Bank of Florida Branches. Acquisition of Community Southern Holdings, Inc. Community Southern Bank’s loans were measured at fair value by discounting both expected principal and interest cash flows using an observable discount rate for similar instruments that a market participant would consider in determining fair value. Additionally, consideration was given to management’s best estimates of default rates and payment speeds. At acquisition, Community Southern Bank’s loan portfolio totaled $170.0 million and was recorded at a fair value of $171.5 million.

Securities	(4) Securities Securities have been classified according to management intent. On March 19, 2015 management transferred all securities classified as held to maturity to available for sale at an estimated fair market value of $69.7 million. The transfer was performed to enhance the interest-rate risk position of the Bank and provide liquidity for future loan growth. As a result of the transfer, the Bank is precluded from classifying securities as held to maturity until March 2017.

It is expected that the securities would not be settled at a price less than the par value of the investments. Because the decline in fair value was attributable to market conditions and not credit quality, and because the Company has the ability and intent to hold these investments until a market price recovery or maturity, these investments are not considered other-than-temporarily The Bank pledged securities with a fair market value of approximately $24.2 million at September 30, 2015 and $25.6 million at December 31, 2014 to secure public funds and other borrowings.

All loans are underwritten in accordance with policies set forth and approved by the Company’s board of directors. The portfolio segments identified by the Company are as follows: Real Estate Mortgage Loans. One-to four-family residential real estate loans are underwritten based on repayment capacity and source, value of the underlying property, credit history and stability. Commercial real estate loans are secured by the subject property. Underwriting standards include, among other factors, loan to value limits, cash flow coverage and general creditworthiness of the obligors. Multi-family real estate loans follow the same underwriting criteria as commercial real estate loans. These loans are generally considered to have more credit risk than traditional one-to four-family residential loans because these loans tend to involve larger loan balances and their repayment is typically dependent upon the successful operation and management of the underlying real estate. Land and construction loans are to finance the construction of owner-occupied and lease properties. These loans are categorized as construction loans during the construction period, later converting to commercial or one-to four-family residential real estate loans after the construction is complete and amortization of the loan begins. Land and construction loans are approved based on an analysis of the borrower and guarantor, the viability of the project and on an acceptable percentage of the appraised value of the property securing the loan. Land and construction loan funds are disbursed periodically based on the percentage of construction completed. The Company carefully monitors these loans with on-site inspections and requires the receipt of lien waivers on funds advanced. Land and construction loans are typically secured by the properties under development or construction, and personal guarantees are typically obtained. Further, to assure that reliance is not placed solely on the value of the underlying property, the Company considers the market conditions and feasibility of proposed projects, the financial condition and reputation of the borrower and guarantors, the amount of the borrower’s equity in the project, independent appraisals, cost estimates and pre-construction sale information. The Company also makes commercial loans on occasion for the purchase of land for future development by the borrower. The Company carefully analyzes the borrower and the intended use of the property and the viability thereof. Commercial Loans. Consumer Loans.

Loans classified as substandard or special mention are reviewed quarterly by the Company for further deterioration or improvement to determine if they are appropriately classified and whether there is any impairment. All loans are graded upon initial issuance. Further, commercial loans over $500,000 are typically reviewed at least annually to determine the appropriate loan grading. In addition, during the renewal process of any loan, as well as if a loan becomes past due, the Company will determine the appropriate loan grade. Loans excluded from the review process above are generally classified as pass credits until: (a) they become past due; (b) management becomes aware of a deterioration in the credit worthiness of the borrower; or (c) the borrower contacts the Company for a modification. In these circumstances, the loan is specifically evaluated for potential classification as to special mention, substandard or even charged-off as a loss. The Company uses the following definitions for risk ratings: Pass Special Mention Substandard Doubtful Loss The following summarizes the loan credit quality (in thousands): Real Estate Mortgage Loans One-to Four-Family Commercial Multi- Land and Commercial Consumer Total Credit Risk Profile by Internally Assigned Grade: At September 30, 2015: Grade: Pass $ 77,013 150,511 16,075 25,471 40,310 4,325 $ 313,705 Special mention 1,369 1,349 — 955 3,312 33 7,018 Substandard 660 828 98 254 352 — 2,192 Total $ 79,042 152,688 16,173 26,680 43,974 4,358 $ 322,915 At December 31, 2014: Grade: Pass $ 52,392 21,385 10,498 6,864 15,788 1,398 $ 108,325 Special mention 316 413 — 211 94 — 1,034 Substandard — 245 124 — 891 — 1,260 Total $ 52,708 22,043 10,622 7,075 16,773 1,398 $ 110,619 The Company 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, credit documentation, public information, and current economic trends, among other factors.

Banking and Thrift [Abstract]
Regulatory Matters	(12) Regulatory Matters Effective January 1, 2015, the Bank became subject to new capital requirements set forth by federal banking regulations. These changes were designed to ensure capital positions remain strong during the events of economic downturns or unforeseen losses. The Company is exempt from consolidated capital requirements as the Federal Reserve Board amended its “small bank holding company” policy statement to generally exempt savings and loan holding companies with less than $1.0 billion in assets from capital requirements. These new requirements create a new capital ratio for common equity Tier 1 capital and increase the Tier 1 capital ratio requirements. Under the new capital regulation for the Bank, the minimum capital ratios consist of a common equity tier 1 ratio of 4.5% of risk-weighted assets, a tier 1 capital ratio of 6.0% of risk-weighted assets, a total capital ratio of 8.0% of risk weighted assets, and a leverage ratio of 4.0%. Common equity tier 1 generally comprises of common stock, additional paid in capital, and retained income. There were changes in the risk weighting of certain assets to better reflect the risk associated with those assets, such as the risk weighting for non-performing loans and certain high volatility commercial real estate acquisitions, development and construction loans. The changes also include additional limitations on the inclusion of deferred tax asset in capital. The Bank made a one-time election to exclude accumulated other comprehensive income from regulatory capital in order to reduce the impact of market volatility on regulatory capital. The following table shows the Bank’s capital amounts and ratios and regulatory thresholds at September 30, 2015 (dollars in thousands): Actual Minimum Minimum To Be Well Amount % Amount % Amount % Common Equity Tier 1 Capital to Risk – Weighted Assets $ 47,679 13.75 % $ 15,604 4.50 % $ 22,539 6.50 % Tier I Capital to Risk-Weighted Assets 47,679 13.75 20,805 6.00 27,741 8.00 Total Capital to Risk-Weighted Assets 49,626 14.31 27,743 8.00 34,679 10.00 Tier I Capital to Total Assets 47,679 10.59 18,009 4.00 22,511 5.00 As of September 30, 2015, the Bank was well capitalized under all capital ratios.

Organization	Organization. On July 14, 2014, the Conversion was completed and the Holding Company became the parent holding company for the Bank. A total of 4,232,000 shares of common stock were sold to depositors and the employee stock ownership plan (“ESOP”) at $10.00 per share through which the Holding Company received gross offering proceeds of approximately $42.3 million. The net proceeds received were $37.4 million after offering costs and the allocation of unearned ESOP shares. The Holding Company owns all the outstanding shares of common stock of the Bank. The Conversion was accounted for as a change in corporate form with the historic basis of the Bank’s assets, liabilities and equity unchanged as a result. In connection with the Conversion, the Holding Company implemented an ESOP, to provide eligible employees the opportunity to own the Company’s Common stock. This plan is a tax-qualified retirement plan for the benefit of all Bank employees. A total of 338,560 shares of common stock issued in the Conversion were acquired by the ESOP. The Bank through its eight full-service banking offices and two loan production offices provides a variety of retail community banking services to individuals and businesses primarily in Hillsborough, Polk, Pasco, and Orange Counties, Florida. The Bank’s deposits are insured up to the applicable limits by the Federal Deposit Insurance Corporation (“FDIC”). Our accounting and reporting policies conform to Accounting Principles Generally Accepted in the United States of America (“GAAP”) and general practices within the banking industry and are described in note 1 to the audited consolidated financial statements in our 2014 Annual Report on Form 10-K, as updated by information in this Form 10-Q. While management believes the sources utilized to arrive at the fair value estimates are reliable, different sources or methods could have yielded different fair value estimates. Such different value estimates could affect future earnings through different values being utilized for the disposition or amortization of the underlying assets and liabilities acquired.
Acquisition Method of Accounting	Acquisition Method of Accounting. Accounting for business combination under GAAP acquisition method prohibits “carrying over” valuation allowances, such as the allowance for loan losses. Uncertainties relating to the expected future cash flows is be reflected in the fair value measurement of the acquired loans and reflected in the purchase price. The Bank will establish loan loss allowances for the acquired loans in periods after the acquisition, but only for losses incurred on these loans due to credit deterioration after acquisition. As a result, the allowance for loan loss reflected in these statements is only that of historical Sunshine Bank.
Purchased Credit-Impaired Loans	Purchased Credit-Impaired Loans. As a result of the Company’s recent acquisition, the Company individually evaluated three PCI loans. These acquired loans were recorded on the acquisition date at fair value. The Company estimates the amount and timing of expected cash flows for each individually analyzed loan. Estimated cash flows in excess of the amount paid is recorded as interest income over the remaining life of the loan. On a quarterly basis, the Company will update the amount of loan principal and interest cash flows expected to be collected, incorporating assumptions regarding default rates, loss severities, the amounts and timing of prepayments and other factors that are reflective of current market conditions. Probable decreases in expected loan principal cash flows trigger the recognition of impairment, which is then measured as the present value of the expected principal loss plus any related foregone interest cash flows discounted at the pool’s effective interest rate. Impairments that occur after the acquisition date are recognized through the allowance for loan losses. Probable and significant increases in expected cash flows would first reverse any previously recorded allowance for loan losses; any remaining increases are recognized prospectively as interest income. The impacts of (i) prepayments, (ii) changes in variable interest rates, and (iii) any other changes in the timing of expected cash flows are recognized prospectively as adjustments to interest income. Disposals of loans, which may include sales of loans, receipt of payments in full by the borrower, or foreclosure, result in removal of the loan from the PCI portfolio.
