Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Significant Accounting Policies	(1) Organization and Significant Accounting Policies Organization. Sunshine Bank is a federal stock savings bank. It was first organized in 1954 as a federal mutual savings and loan association under the name First Federal Savings and Loan Association of Plant City. In 1975, the Bank changed its name to Sunshine State Federal Savings and Loan Association. In 2014, the Bank changed its name to Sunshine Bank. The Bank through its eighteen full service banking offices provides a variety of retail community banking services to individuals and businesses primarily in Hillsborough, Polk, Manatee, Sarasota, Pasco, Orange, Brevard, Osceola, and Seminole Counties, Florida. 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 2016 Annual Report on Form 10-K, as updated by information in this Form 10-Q. These condensed consolidated financial statements and notes are presented in accordance with the instructions for Form 10-Q, and accordingly, certain information and disclosures normally included in audited consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. 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 June 30, 2017, and the results of operations for the three and six month periods ended June 30, 2017 and 2016. The results of operations for the three and six month periods ended June 30, 2017, are not necessarily indicative of the results to be expected for the full year or any other period. The preparation of financial statements in conformity with GAAP requires the use of estimates and assumptions that affect the reported amounts in the consolidated financial statements and notes. While management believes the sources utilized to arrive at the estimates are reliable, different sources or methods could have yielded different 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. Material estimates that are particularly susceptible to significant changes include the allowance for loan losses, the valuation of goodwill and other intangibles, deferred income taxes, and purchase accounting related adjustments. Principles of Consolidation. Share-based Compensation. Comprehensive Income. Recent Accounting Standards Update. During May 2017, the FASB issued new guidance related to Stock Compensation, Scope of Modification Accounting During March 2017, the Financial Accounting Standards Board (“FASB”) issued new guidance new guidance related to Premium Amortization on Purchased Callable Debt Securities During January 2017, the FASB issued new guidance new guidance related to, Simplifying the Test for Goodwill Impairment.

As of June 30, 2017 one security has been in a loss position for greater than twelve months. As of December 31, 2016 no security was in a loss position for greater than twelve months. In considering the credit quality of the issuers, the nature and cause of the unrealized loss, the severity and length of time in an unrealized loss position, and other factors, it is expected that the securities would not be settled at a price less than the par value of the investments. Management determined that the decline in fair value is attributable to fluctuations in interest rates and other market conditions and not a deterioration of the credit quality of the issuers. 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 impaired. The Company pledged securities with a fair market value of approximately $39.8 million at June 30, 2017 and $22.1 million at December 31, 2016 to secure public funds and other borrowings. Securities available for sale sold, are summarized as follows (in thousands) For the three months ended For the six months ended June 30, 2017 June 30, 2016 June 30, 2017 June 30, 2016 Proceeds received from sale $ — $ 8,872 $ — $ 12,920 Gross Gains on sale $ — $ 105 $ — $ 131

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 Loans. One-to-four-family residential real estate loans are underwritten based on the borrower’s repayment capacity and source, value of the underlying property, credit history and stability. Commercial and multifamily real estate loans are secured by the subject property and are underwritten based on loan to value limits, cash flow coverage and general creditworthiness of the obligors. 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. Construction and Land 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 loans after the construction is complete and amortization of the loan begins. Real estate development 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. Construction loan funds are disbursed periodically based on the percentage of construction or development completed. The Company carefully monitors these loans with on-site inspections and requires the receipt of lien waivers on funds advanced. Construction and land 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 loans on occasion for the purchase of land for future development by the borrower. Land loans are extended for the future development for either commercial or residential use by the borrower. The Company carefully analyzes the intended use of the property and the viability thereof. Home equity loans consists of either revolving line of credit, term, or second mortgage loans secured by one-to-four residential real estate. These loans have similar risk characteristics to one-to-four family loans and are secured by a first or second mortgage on the borrower’s principal residence or their second/vacation home (excluding investment/rental property). There are minimum credit score standards, maximum debt to income ratios and credit requirements on each home equity product. Home equity lines of credit are variable rate based on an index of Wall Street Journal prime rate with a margin. Commercial Loans. Consumer Loans.

The Company analyzes loans individually by classifying the loans as to credit risk. 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, multi-family and commercial real estate loans are generally reviewed periodically 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.

Regulatory Matters

Banking and Thrift [Abstract]
Regulatory Matters	(11) 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 nonperforming 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. In order to avoid limitations on distributions, including dividend payments, and certain discretionary bonus payments to executive officers, an institution must hold a capital conservation buffer above its minimum risk-based capital requirements. As of June 30, 2017 the Bank’s capital conservation buffer was 5.43% exceeding the minimum of 1.25% for 2017. The following table shows the Bank’s capital amounts and ratios and regulatory thresholds at June 30, 2017 and December 31, 2016.

Organization	Organization. Sunshine Bank is a federal stock savings bank. It was first organized in 1954 as a federal mutual savings and loan association under the name First Federal Savings and Loan Association of Plant City. In 1975, the Bank changed its name to Sunshine State Federal Savings and Loan Association. In 2014, the Bank changed its name to Sunshine Bank. The Bank through its eighteen full service banking offices provides a variety of retail community banking services to individuals and businesses primarily in Hillsborough, Polk, Manatee, Sarasota, Pasco, Orange, Brevard, Osceola, and Seminole Counties, Florida. 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 2016 Annual Report on Form 10-K, as updated by information in this Form 10-Q. These condensed consolidated financial statements and notes are presented in accordance with the instructions for Form 10-Q, and accordingly, certain information and disclosures normally included in audited consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. 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 June 30, 2017, and the results of operations for the three and six month periods ended June 30, 2017 and 2016. The results of operations for the three and six month periods ended June 30, 2017, are not necessarily indicative of the results to be expected for the full year or any other period. The preparation of financial statements in conformity with GAAP requires the use of estimates and assumptions that affect the reported amounts in the consolidated financial statements and notes. While management believes the sources utilized to arrive at the estimates are reliable, different sources or methods could have yielded different 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. Material estimates that are particularly susceptible to significant changes include the allowance for loan losses, the valuation of goodwill and other intangibles, deferred income taxes, and purchase accounting related adjustments.
