Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | (1) Summary of Significant Accounting Policies (a) Nature of operations and principles of consolidation The Consolidated Financial Statements of CenterState Bank Corporation (the “Company”) include the accounts of the Company, and its wholly owned subsidiaries CenterState Bank, N.A., R4ALL, Inc. and CSFL Insurance Corp. All significant intercompany accounts and transactions have been eliminated in consolidation. At December 31, 2018, the Company, through its subsidiary bank, operated as a community bank headquartered in the state of Florida, providing traditional retail, commercial, mortgage, wealth management and SBA services throughout its Florida, Georgia and Alabama branch network and customer relationships in neighboring states. The Company’s primary deposit products are checking, savings and term certificate accounts, and its primary lending products include commercial real estate loans, residential real estate loans, commercial loans and consumer loans. Substantially all loans are secured by commercial real estate, residential real estate, business assets or consumer assets. There are no significant concentrations of loans to any one industry or customer. However, the customers’ ability to repay their loans is dependent on the real estate and general economic conditions in the area. The Company also provides correspondent banking and capital markets services to over 600 community banks nationwide. R4ALL, Inc. is a non bank subsidiary incorporated during the third quarter of 2009. The primary purpose of this subsidiary is to purchase, hold, and dispose of troubled assets acquired from the Company’s subsidiary bank. CSFL Insurance Corp. is a non bank subsidiary incorporated during the fourth quarter of 2015. The primary purpose of this subsidiary is to function as a captive insurance subsidiary pursuant to Section 831(b) of the U.S. Tax Code. The following is a description of the basis of presentation and the significant accounting and reporting policies, which the Company follows in preparing and presenting its Consolidated Financial Statements. (b) Use of estimates To prepare financial statements in conformity with U.S. generally accepted accounting principles, management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided. Significant items subject to estimates and assumptions include allowance for loan losses, fair values of financial instruments, useful life of intangibles and valuation of goodwill, fair value estimates of stock-based compensation, fair value estimates of OREO, and deferred tax assets. Actual results could differ from these estimates. (c) Cash flow reporting For purposes of the statement of cash flows, the Company considers cash and due from banks, federal funds sold, money market and non-interest bearing deposits in other banks with a purchased maturity of three months or less to be cash equivalents. Net cash flows are reported for customer loan and deposit transactions, interest bearing deposits in other financial institutions, federal funds purchased, repurchase agreements, proceeds from capital offering and other borrowed funds. (d) Interest bearing deposits in other financial institutions Interest bearing deposits in other financial institutions mature within one year and are carried at cost and are included in Cash and Due From Banks in the Consolidated Balance Sheets. (e) The Company engages in trading activities for its own account. Securities that are held principally for resale in the near term are recorded at fair value with changes in fair value included in earnings. Interest is included in net interest income. (f) Investment Debt Securities Debt securities are classified as held to maturity and carried at amortized cost when management has the positive intent and ability to hold them to maturity. Debt securities not classified as held to maturity or trading are classified as available for sale. Debt s ecurities available for sale are carried at fair value, with unrealized holding gains and losses reported in other comprehensive income, net of tax. Interest income includes amortization of purchase premium or discount. Premiums on securities are amortized to the earliest call date. Discounts on securities are amortized on the level-yield method without anticipating prepayments, except for mortgage backed securities where prepayments are anticipated. Gains and losses on sales are recorded on the trade date and determined using the specific identification method. Securities are evaluated for other-than-temporary impairment (“OTTI”) on at least an annual basis, and more frequently when economic or market conditions warrant such an evaluation. For securities in an unrealized loss position, management considers the extent and duration of the unrealized loss, and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or it is more likely than not that it will be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: 1) OTTI related to credit loss, which must be recognized in the income statement; and 2) other-than-temporary impairment related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. (g) Bond commissions revenue recognition Bond sales transactions and related revenue and expenses are recorded on a settlement date basis. The effect on the financial statements of using the settlement date basis rather than the trade date basis is not material. (h) Loans held for sale Effective January 1, 2018, mortgage loans originated and intended for sale in the secondary market are carried at fair value with changes in fair value recognized in current period earning. For periods prior to December 31, 2018, mortgage loans held for sale were carried at the lower of aggregate cost or fair value, as determined by outstanding commitments from investors. Net unrealized losses, if any, are recorded as a valuation allowance and charged to earnings. Mortgage loans held for sale are generally sold with servicing rights released. Gains and losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold. (i) Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their outstanding unpaid principal balance net of purchase premiums and discounts, deferred loan fees and costs, and an allowance for loan losses. Interest income is accrued on the unpaid principal balance. The recorded investment in a loan excludes accrued interest receivable, deferred fees, and deferred costs because they are not considered material. A loan is considered a troubled debt restructured loan based on individual facts and circumstances. A modification may include either an increase or reduction in interest rate or deferral of principal payments or both. Loans for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties, are considered troubled debt restructurings. The Company classifies troubled debt restructured loans as impaired and evaluates the need for an allowance for loan losses on a loan-by-loan basis. An allowance for loan losses is based on either the present value of estimated future cash flows or the estimated fair value of the underlying collateral. Loans retain their accruing or non-accruing status at the time of modification. Loan origination fees and the incremental direct cost of loan origination, are deferred and recognized in interest income without anticipating prepayments over the contractual life of the loans. If the loan is prepaid, the remaining unamortized fees and costs are charged or credited to interest income. Amortization ceases for non-accrual loans. A loan is moved to non-accrual status in accordance with the Company’s policy typically after 90 days of non-payment, or less than 90 days of non-payment if management determines that the full timely collection of principal and interest becomes doubtful. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on non-accrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. Non-accrual loans and loans past due 90 days still on accrual include both smaller balance homogeneous loans that are collectively evaluated for impairment and individually classified impaired loans. Single family home loans, consumer loans and smaller commercial, land, development and construction loans (less than $ 500 ) are monitored by payment history, and as such, past due payments is generally the triggering mechanism to determine non - accrual status. Larger (greater than $ 500 ) commercial, land, development and construction loans are monitored on a loan level basis, and therefore in these cases it is more likely that a loan may be placed on non - accrual status before it becomes 90 days past due. All interest accrued but not received for loans placed on non-accrual is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Non real estate consumer loans are typically charged off no later than 120 days past due. The Company, considering current information and events regarding the borrower’s ability to repay their obligations, considers a loan to be impaired when it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. When a loan is considered to be impaired, the amount of the impairment is measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, the secondary market value of the loan, or the fair value of the collateral for collateral dependent loans. Interest income on impaired loans is recognized in accordance with the Company’s non-accrual policy. Impaired loans are written down to the extent that principal is judged to be uncollectible and, in the case of impaired collateral dependent loans where repayment is expected to be provided solely by the underlying collateral and there is no other available and reliable sources of repayment, are written down to the lower of cost or collateral value less estimated selling costs. Impairment losses are included in the allowance for loan losses. Large groups of smaller balance homogeneous loans, such as consumer and residential real estate loans, are collectively evaluated for impairment, and accordingly, they are not separately identified for impairment disclosures. (j) Purchased credit-impaired loans As a part of business acquisitions, the Company acquires loans, some of which have shown evidence of credit deterioration since origination. These purchased credit-impaired (“PCI”) loans were determined to be credit impaired based on specific risk characteristics of the loan, including, but not limited to loans on non-accrual status, loans with insufficient cash flow, past due loans, high loan-to-value ratios, loans in process of foreclosure, or any TDR with loss potential. The Company, as a purchaser, is permitted to aggregate credit impaired loans acquired in the same fiscal quarter into one or more pools, provided that the loans have common risk characteristics. A pool is then accounted for as a single asset with a single composite interest rate and an aggregate expectation of cash flows. For the loan portfolios acquired, the Company aggregated the commercial, consumer, and residential loans into pools of loans with common risk characteristics for each institution acquired. These acquired loans were recorded at the acquisition date fair value, and after acquisition, losses are recognized through the allowance for loan losses. The Company estimates the amount and timing of expected cash flows for each acquired loan pool and the expected cash flows in excess of the amount paid is recorded as interest income over the remaining life of the loan pools. As frequently as quarter or as long as annually, the Company updates 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 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 provision for loan losses. Probable and significant increases in expected principal cash flows would first reverse any previously recorded allowance for loan losses; any remaining increases are recognized prospectively as interest income over the life of the pool. 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 over the life of the pool. 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 purchased credit impaired portfolio. (k) Concentration of credit risk Most of the Company’s business activity is with customers located within Southeastern United States largely in Florida, also in Alabama and Georgia. Therefore, the Company’s exposure to credit risk is significantly affected by changes in the economy and the real estate market within Southeast, primarily in Florida. (l) Allowance for loan losses The allowance for loan losses is a valuation allowance for probable incurred credit losses. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Management estimates the allowance balance required using past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, economic conditions, and other factors. Allocations of the allowance may be made for specific loans, but the entire allowance is available for any loan that, in management’s judgment, should be charged-off. The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. The general component covers loans that are not individually classified as impaired and is based on historical loss experience adjusted for current factors. A loan is impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. Loans, for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties, are considered troubled debt restructurings and classified as impaired. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. If a loan is impaired, a portion of the allowance is allocated so that the loan is reported, net, at the present value of estimated future cash flows using the loan’s existing rate or at the fair value of collateral if repayment is expected solely from the collateral. Commercial, commercial real estate, land, acquisition and development, and construction loans over $500 are individually evaluated for impairment. Large groups of smaller balance homogeneous loans, such as consumer and residential real estate loans, are collectively evaluated for impairment, and accordingly, they are not separately identified for impairment disclosures. Troubled debt restructurings are separately identified for impairment disclosures and are measured at the present value of estimated future cash flows using the loan’s effective rate. If a troubled debt restructuring is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of the collateral. For troubled debt restructurings that subsequently default, the Company determines the amount of reserve in accordance with the accounting policy for the allowance for loan losses. The general component covers non-impaired loans and is based on historical loss experience adjusted for current factors. The historical loss experience is determined by portfolio segment and is based on the actual loss history experienced by the Company over the most recent two years. The portfolio segments identified by the Company are residential loans, commercial real estate loans, construction and land development loans, commercial and industrial and consumer and other. This actual loss experience is supplemented with other economic factors based on the risks present for each portfolio segment. These economic factors include consideration of the following: levels of and trends in delinquencies and impaired loans; volume and severity of adversely classified or graded loans; levels of and trends in charge-offs and recoveries; trends in volume and terms of loans; effects of any changes in risk selection and underwriting standards; other changes in lending policies, procedures, and practices; experience, ability, and depth of lending management and other relevant staff; national and local economic trends and conditions; industry conditions; and effects of changes in credit concentrations. The Company segregates and evaluates its loan portfolio through the five portfolio segments: residential real estate, commercial real estate, land/ land development/construction, commercial and consumer/other. Residential real estate loans are a mixture of fixed rate and adjustable rate residential mortgage loans, including first mortgages, second mortgages or home equity lines of credit. As a policy, the Company holds adjustable rate loans and sells a portion of its fixed rate loan originations into the secondary market. Changes in interest rates or market conditions may impact a borrower’s ability to meet contractual principal and interest payments. Residential real estate loans are secured by real property. Commercial real estate loans include loans secured by office buildings, warehouses, retail stores and other property located in or near our markets. These loans are originated based on the borrower’s ability to service the debt and secondarily based on the fair value of the underlying collateral. Land/land development/construction loans include residential and commercial real estate loans and include a mixture of owner occupied and non-owner occupied. The majority of the loans in this category are land related, either undeveloped land, land held for development, residential building lots and commercial building lots. Generally the terms are three to five years, with a potential for renewal at maturity. Commercial loans consist of small-to medium-sized businesses including professional associations, medical services, retail trade, transportation, wholesale trade, manufacturing and tourism. Commercial loans are derived from our market areas and underwritten based on the borrower’s ability to service debt from the business’s underlying cash flows. As a general practice, we obtain collateral such as inventory, accounts receivable, equipment or other assets although such loans may be uncollateralized but guaranteed. Consumer and other loans include automobiles, boats, mobile homes without land, or uncollateralized but personally guaranteed loans. These loans are originated based primarily on credit scores, debt-to-income ratios and loan-to-value ratios. The Company evaluates the loans acquired from the Gulfstream, First Southern, Community Bank, First National, Platinum and Gateway acquisitions that were not PCI loans as individual loan portfolio segments. The Company considered the levels of and trends in non-performing loans, past-due loans, adverse loan grade classification changes, historical loss rates, environmental factors and impaired loans in arriving at its estimate. The general loan loss allowance recorded for these performing loans acquired from Gulfstream is allocated between the five portfolio segments described above in Note 5. (m) Transfer of financial assets Transfers of financial assets are accounted for as sales, when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Company, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. (n) Other repossessed real estate owned Assets acquired through or instead of loan foreclosure are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. If fair value declines subsequent to foreclosure, a valuation allowance is recorded through expense. Operating costs after acquisition are expensed. Repossessed real estate is included in other repossessed real estate owned and other repossessed assets other than real estate is included in Prepaid Expenses and Other Assets in the Consolidated Balance Sheets. (o) Premises and equipment Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation. Depreciation is provided on a straight-line basis over the estimated useful lives of the related assets. Buildings are depreciated over a 39 year period, and furniture, fixtures and equipment are depreciated over their related useful life (3 to 15 years). Leasehold improvements are depreciated over the shorter of their useful lives or the term of the lease. Major renewals and betterments of property are capitalized; maintenance, repairs, and minor renewals and betterments are expensed in the period incurred. Upon retirement or other disposition of the asset, the asset cost and related accumulated depreciation are removed from the accounts, and gains or losses are included in income. (p) Software costs Costs of software developed for internal use, such as those related to software licenses, programming, testing, configuration, direct materials and integration, are capitalized and included in premises and equipment. Included in the capitalized costs are those costs related to both our personnel and third party consultants involved in the software development and installation. Once placed in service, the capitalized asset is amortized on a straight-line basis over its estimated useful life, generally three to five years. Capitalized costs of software developed for internal use are reviewed periodically for impairment. (q) Federal Home Loan Bank (FHLB), Federal Reserve Bank (FRB) and other stock The Company’s subsidiary bank is a member of the FHLB and FRB system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB, FRB and other stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income. (r) Bank owned life insurance (BOLI) The Company, through its subsidiary bank, has purchased life insurance policies on certain key executives or acquired through various bank acquisitions. Bank owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement. (s) Goodwill and other intangible assets Goodwill resulting from business combinations prior to January 1, 2009 represents the excess of the purchase price over the fair value of the net assets of businesses acquired. Goodwill resulting from business combinations after January 1, 2009, is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually. The Company has selected November 30 as the date to perform the annual impairment test. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Goodwill is the only intangible asset with an indefinite life on the Company’s balance sheet. The core deposit intangibles are intangible assets arising from either whole bank acquisitions or branch acquisitions. They are initially measured at fair value and then amortized over a ten-year period on an accelerated basis using the projected decay rates of the underlying core deposits. As a part of normal business operations, the Company originates residential mortgage loans that have been pre-approved by secondary investors. The terms of the loans are set by the secondary investors, and the purchase price that the investor will pay for the loan is agreed to prior to the commitment of the loan by the Company. Generally within three weeks after funding, the loans are transferred to the investor in accordance with the agreed-upon terms. The Company records gains from the sale of these loans on the settlement date of the sale equal to the difference between the proceeds received and the carrying amount of the loan. The gain generally represents the portion of the proceeds attributed to servicing release premiums received from the investors and the realization of origination fees received from borrowers which were deferred as part of the carrying amount of the loan. Between the initial funding of the loans by the Company and the subsequent reimbursement by the investors, the Company carries the loans on its balance sheet at the lower of cost or market. The fair value of the underlying commitment is not material to the Consolidated Financial Statements. The standard structure of mortgage loan sales provides for the Company to retain a portion of the cash flow from the interest payments received on the loan. Fees for servicing loans for investors are based on the outstanding principal balance of the loans serviced and are recognized as income when earned. This cash flow is commonly known as a servicing spread. The servicing spread is recognized as a servicing asset to the extent the spread exceeds adequate compensation for the servicing function and recorded as a component of Other Intangible Assets in the Consolidated Balance Sheets. The fair value of the servicing asset is measured on a recurring basis at the present value of future cash flows using market-based discount assumptions. The future cash flows for each asset are based on their unique characteristics and market-based assumptions for prepayment speeds, default and voluntary prepayments. Adjustments to fair value are recorded as a component of Mortgage Banking Revenue. The value of our servicing portfolio is periodically independently evaluated. (t) FDIC Indemnification Asset The FDIC Indemnification Asset represented the estimated amounts due from the FDIC pursuant to the Loss Share Agreements related to the acquisitions of the three failed banks acquired in 2010, two in 2012 and assumed two additional pursuant to the Company’s 2014 acquisition of First Southern. At acquisition, the FDIC Indemnification Asset represented the discounted value of the FDIC’s reimbursed portion of the estimated losses the Company expects to realize on the loans and other real estate (“Covered Assets”) acquired as a result of the acquisitions. The range of discount rates used on the FDIC Indemnification Asset was 1.21% to 4.53%. As losses were realized on Covered Assets, the portion that the FDIC paid the Company in cash for principal and up to 90 days of interest reduced the FDIC Indemnification Asset. On a quarterly basis, the Company evaluated the FDIC Indemnification Asset to determine if the estimated losses on Covered Assets supported the amount recorded as the FDIC Indemnification Asset. Income accretion was recognized during the loss share period. If the expectation of future losses declined, the income accretion was reduced prospectively over the lesser of the term of the loss share agreement and the estimated remaining life of the Covered Asset. On February 3, 2016, the FDIC bought out the remaining FDIC loss share agreements. As such, the FDIC indemnification asset was written-off effectively accelerating all future FDIC indemnification asset amortization expense as well as ending any future FDIC indemnification income. (u) Loan commitments and related financial instruments Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded. (v) Stock-based compensation Compensation cost is recognized for stock options and restricted stock awards issued to employees, based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the date of grant is used for restricted stock awards. During 2014 the Company initiated a Long-Term Incentive Plan which included Performance Share Units (“PSUs”). The Monte-Carlo Simulation model was used to estimate fair value of the PSUs at the grant date. Compensation cost is recognized over the required service period, generally defined as the vesting period. (w) Income taxes Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. The Company recognizes interest and/or penalties related to income tax matters in other expenses.

Available for sale debt securities pledged at December 31, 2018 and 2017 had a carrying amount (estimated fair value) of $961,721 and $255,788, respectively. These securities were pledged primarily to secure public deposits and repurchase agreements. At year-end 2018 and 2017, there were no holdings of available for sale securities of any one issuer, other than the U.S. Government and its agencies, in an amount greater than 10% of shareholders’ equity.

Because the decline in fair value is attributable to changes in interest rates and illiquidity, and not credit quality, and because the Company does not have the intent to sell these mortgage-backed securities and it is likely that it will not be required to sell the securities before their anticipated recovery, the Company does not consider these securities to be other-than-temporarily impaired at December 31, 2018. Municipal securities: Unrealized losses on municipal securities have not been recognized into income because the issuers bonds are of high quality, and because management does not intend to sell these investments or more likely than not will not be required to sell these investments before their anticipated recovery. The fair value is expected to recover as the securities approach maturity.

Loans Receivable Held For Sale Net [Abstract] | |
Loans Held for Sale | (4) For periods prior to December 31, 2017, mortgage loans held for sale were valued at the lower of cost or fair value. Effective January 1, 2018, the Company elected to account for these loans under the fair value option with changes in fair value recognized in current period earnings. At the date of funding of the loan, the funded amount of the loan, the relative derivative asset or liability of the associated interest rate lock commitment, less direct costs, becomes the initial recorded investment in the loan held for sale. Such amount approximates the fair value of the loan. This change was accounted for on a prospective basis. Net gains from changes in estimated fair value of mortgage loans held for sale were $1,081 at December 31, 2018. The total unpaid principal balance of loans held for sale was $39,318 at December 31, 2018. No loans held for sale at December 31, 2018 were past due or on non-accrual. The table below summarizes the activity in mortgage loans held for sale for the years ended December 31, 2018 and 2017. December 31, 2018 2017 Beginning balance $ 19,647 $ 2,285 Effect from acquisitions 8,959 — Loans originated 403,492 93,642 Proceeds from sales (403,583 ) (77,791 ) Change in fair value 1,081 — Net realized gain on sales 10,803 1,511 Ending balance $ 40,399 $ 19,647 As loans are closed, they are typically sold at prices specified in the forward contracts. Gains or losses may arise if the yields of the loans delivered vary from those specified in the forward contracts. Derivative mortgage loan commitments, or interest rate locks, are also utilized and relate to the origination of a mortgage that will be held for sale upon funding. The Company began utilizing these derivative financial instruments on its loans held for sale in year 2018 to manage interest rate risk and not for speculative purposes. The changes in fair value of $1,081, the net realized gain on sales of loans held for sale of $10,803, and the net unrealized gain on mortgage banking derivatives of $614 are the main components of Mortgage Banking Revenue as reported in the Company’s Consolidated Statements of Income and Comprehensive Income. The table below summarizes the notional amounts for interest rate lock commitments, best efforts forward trades and MBS forward trades pertaining to loans held for sale at December 31, 2018. Notional Interest rate lock commitments $ 49,545 Best efforts forward trades 61,865 MBS forward trades 30,000 Total derivative instruments $ 141,410 Mortgage banking derivatives, which are included in Other Assets and Other Liabilities on the Company’s Consolidated Balance Sheets, used in the ordinary course of business consist of forward sales contracts and interest rate lock commitments on residential mortgage loans. Forward sales contracts represent future commitments to deliver loans at a specified price and by a specified date and are used to manage interest rate risk on loan commitments and mortgage loans held for sale. Rate lock commitments represent commitments to fund loans at a specific rate and by a specified expiration date. These derivatives involve underlying items, such as interest rates, and are designed to mitigate risk. Notional amounts are amounts on which calculations and payments are based, but which do not represent credit exposure, as credit exposure is limited to the amounts required to be received or paid. |

When the Company modifies the terms of a loan, it usually either reduces the monthly payment and/or interest rate for generally twelve to twenty-four months. The Company has not forgiven any material principal amounts on any loan modifications to date. The Company has $9,477 of TDRs. Of this amount $8,475 are performing pursuant to their modified terms, and $1,002 are not performing and have been placed on non-accrual status and included in our non-performing loans (“NPLs”). TDRs as of December 31, 2018 and 2017 quantified by loan type classified separately as accrual (performing loans) and non-accrual (non-performing loans) are presented in the table below. As of December 31, 2018 Accruing Non-Accrual Total Real estate loans: Residential $ 5,848 $ 386 $ 6,234 Commercial 1,837 566 2,403 Land, development, construction 77 41 118 Total real estate loans 7,762 993 8,755 Commercial 577 — 577 Consumer and other 136 9 145 Total TDRs $ 8,475 $ 1,002 $ 9,477 As of December 31, 2017 Accruing Non-Accrual Total Real estate loans: Residential $ 7,737 $ 364 $ 8,101 Commercial 3,286 306 3,592 Land, development, construction 332 — 332 Total real estate loans 11,355 670 12,025 Commercial 556 — 556 Consumer and other 170 28 198 Total TDRs $ 12,081 $ 698 $ 12,779 The Company’s policy is to return non-accrual TDR loans to accrual status when all the principal and interest amounts contractually due, pursuant to its modified terms, are brought current and future payments are reasonably assured. The Company’s policy also considers the payment history of the borrower, but is not dependent upon a specific number of payments. The Company recorded a provision for loan loss expense of $77, $265 and $454 and partial charge offs of $44, $72 and $209 on TDR loans during the periods ending December 31, 2018, 2017 and 2016, respectively. Loans are modified to minimize loan losses when management believes the modification will improve the borrower’s financial condition and ability to repay the loan. The Company typically does not forgive principal. The Company generally either reduces interest rates or decreases monthly payments for a temporary period of time and those reductions of cash flows are capitalized into the loan balance. The Company may also extend maturities, convert balloon loans to longer term amortizing loans, or vice versa, or change interest rates between variable and fixed rate. Each borrower and situation is unique and management tries to accommodate the borrower and minimize the Company’s potential losses. Approximately 89% of the Company’s TDRs are current pursuant to their modified terms, and $1,002, or approximately 11% of the Company’s total TDRs are not performing pursuant to their modified terms. There does not appear to be any significant difference in success rates with one type of concession versus another. Loans modified as TDRs during the twelve month periods ending December 31, 2018, 2017 and 2016 were $1,830, $2,258 and $4,079. The Company recorded a loan loss provision of $9, $14 and $229 for loans modified during the twelve-month periods ending December 31, 2018, 2017 and 2016. The following table presents loans by class modified as TDRs for which there was a payment default within twelve months following the modification during the years ending December 31, 2018, 2017 and 2016.

The Company recorded $8 and $76 in provision for loan loss expense and $8 and $77 in partial charge offs during the years ending December 31, 2017 and 2016, respectively, on TDR loans that subsequently defaulted as described above. The Company has allocated $334 and $601 of specific reserves to customers whose loan terms have been modified in troubled debt restructurings as of December 31, 2018 and 2017. The Company has not committed to lend additional amounts to customers with outstanding loans that are classified as troubled debt restructurings.

The Company analyzes loans individually by classifying the loans as to credit risk. This analysis is performed on at least an annual basis. The Company uses the following definitions for risk ratings: Special Mention: Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date. Substandard: Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Doubtful: Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered to be pass rated loans. As of December 31, 201 8 and 2017 , and based on the most recent analysis performed, the risk category of loans by class of loans, excluding purchased credit - impaired loans accounted for pursuant to ASC Topic 310-30, is presented below. The increase in loans categorized as special mention between the periods presented is due to the acquisitions of Sunshine and Harbor on January 1, 2018 and Charter on September 1 , 201 8 , respectively. As of December 31, 2018 Loan Category Pass Special Mention Substandard Doubtful Residential real estate $ 1,633,810 $ 41,522 $ 26,782 $ — Commercial real estate 4,246,687 160,981 46,430 — Land/dev/construction 610,631 20,586 4,345 — Commercial 1,137,272 40,836 5,272 — Consumer 202,701 247 738 — Total $ 7,831,100 $ 264,172 $ 83,568 $ — As of December 31, 2017 Loan Category Pass Special Mention Substandard Doubtful Residential real estate $ 987,472 $ 20,435 $ 17,396 $ — Commercial real estate 2,411,085 115,942 19,116 — Land/dev/construction 217,555 17,699 562 — Commercial 674,764 14,186 4,551 — Consumer 106,735 139 606 — Total $ 4,397,611 $ 168,401 $ 42,231 $ — The Company considers the performance of the loan portfolio and its impact on the allowance for loan losses. For residential and consumer loan classes, the Company also evaluates credit quality based on the aging status of the loan, which was previously presented, and by payment activity. The following table presents the recorded investment in residential and consumer loans, excluding purchased credit-impaired loans accounted for pursuant to ASC Topic 310-30, based on payment activity as of December 31, 2018 and 2017: As of December 31, 2018 Residential Consumer Performing 1,690,626 203,121 Non-performing 11,488 565 Total 1,702,114 203,686 As of December 31, 2017 Residential Consumer Performing $ 1,018,196 $ 107,107 Non-performing 7,107 373 Total $ 1,025,303 $ 107,480 Purchased Credit - Impaired (“PCI”) Loans: Income is recognized on PCI loans pursuant to ASC Topic 310-30. A portion of the fair value discount has been ascribed as an accretable yield that is accreted into interest income over the estimated remaining life of the loans. The remaining non-accretable difference represents cash flows not expected to be collected. The table below summarizes the total contractually required principal and interest cash payments, management’s estimate of expected total cash payments and carrying value of the loans as of December 31, 2018, 2017 and 2016. Contractually required principal and interest payments have been adjusted for estimated prepayments.

The Company adjusted its estimates of future expected losses, cash flows and renewal assumptions during the current year. These adjustments resulted in an increase in expected cash flows and accretable yield, and a decrease in the non-accretable difference. The Company reclassified approximately $22,469, $4,707 and $6,220 from non-accretable difference to accretable yield during the twelve-month periods ending December 31, 2018, 2017 and 2016, respectively, to reflect the adjusted estimates of future expected cash flows. The Company recognized approximately $35,944 of accretion income during the twelve-month period ending December 31, 2018.

Fair Value Disclosures [Abstract] | |
Fair Value | (7 ) Fair value Generally accepted accounting principles establish a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. The fair values of available for sale debt securities are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs) or matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs). The fair values of corporate debt securities are calculated using market indicators such as broker quotes (Level 2). The fair values of trading securities are determined as follows: (1) for those securities that have traded prior to the date of the consolidated balance sheet but have not settled (date of sale) until after such date, the sales price is used as the fair value; and, (2) for those securities which have not traded as of the date of the consolidated balance sheet, the fair value was determined by broker price indications of similar or same securities. The Company has the rights to service a portfolio of Fannie Mae ("FNMA") and other loans sold on a servicing retained basis. The fair value of mortgage servicing assets are measured when the loan is sold and subsequently measured at fair value on a recurring basis. Management uses a model operated and maintained by a third party to calculate the present value of future cash flows using the third party's market-based assumptions. The future cash flows for each asset are based on the asset's unique characteristics and the third party's market-based assumptions for prepayment speeds, default and voluntary prepayments (Level 2). Adjustments to fair value are recorded as a component of Mortgage Banking Revenue in the Consolidated Statements of Income and Comprehensive Income. Effective January 1, 2018, the Company elected to account for mortgage loans held for sale under the fair value option with changes in fair value recognized in current period earnings. For periods prior to December 31, 2017, these loans were valued at the lower of cost or fair value. These loans are intended for sale and the Company believes that the fair value is the best indicator of the resolution of these loans (Level 2). In conjunction with the fair value election on loans held for sale, Mortgage banking uses derivative forward sales contracts and interest rate lock commitments on residential mortgage loans. Fair values of these mortgage derivatives are estimated based on changes in market prices for mortgage forward trades and mortgage interest rates (Level 2) and estimated pull through percentages from the date the interest on the loan is locked (Level 3). The Company has the rights to service a portfolio of Fannie Mae ("FNMA") and other government guaranteed loans sold on a servicing retained basis. Mortgage servicing assets are measured at fair value when the loan is sold and subsequently measured at fair value on a recurring basis utilizing Level 2 inputs. Management uses a model operated and maintained by a third party to calculate the present value of future cash flows using the third party's market-based assumptions. The future cash flows for each asset are based on the asset's unique characteristics and the third party's market-based assumptions for prepayment speeds, default and voluntary prepayments. Adjustments to fair value are recorded as a component of Mortgage Banking Revenue in the Consolidated Statements of Income and Comprehensive Income. The fair value of interest rate swap derivatives is based on valuation models using observable market data as of the measurement date (Level 2). The derivatives are traded in an over-the-counter market where quoted market prices are not always available. Therefore, fair values of derivatives are determined using quantitative models that utilize multiple market inputs. The inputs will vary based on the type of derivative, but could include interest rates, prices and indices to generate continuous yield or pricing curves, prepayment rates, and volatility factors to value the position. The majority of market inputs are actively quoted and can be validated through external sources, including brokers, market transactions and third-party pricing services. The fair value of impaired loans with specific valuation allowance for loan losses and other real estate owned is based on recent real estate appraisals. For residential real estate impaired loans and other real estate owned, appraised values are based on the comparative sales approach. For commercial and commercial real estate impaired loans and other real estate owned, appraisers may use either a single valuation approach or a combination of approaches such as comparative sales, cost or the income approach. A significant unobservable input in the income approach is the estimated income capitalization rate for a given piece of collateral. At December 31, 2018, the range of capitalization rates utilized to determine the fair value of the underlying collateral ranged from 7% to 10%. Adjustments to comparable sales may be made by the appraiser to reflect local market conditions or other economic factors and may result in changes in the fair value of a given asset over time. As such, the fair value of impaired loans and other real estate owned are considered a Level 3 in the fair value hierarchy. Assets and liabilities measured at fair value on a recurring basis are summarized below.

The Company recorded a provision for loan loss expense of $1,363 and $842 on these loans during the years ending 2018 and 2017, respectively. Other real estate owned had a decline in fair value of $482 and $682 during the twelve-month periods ending December 31, 2018 and 2017, respectively. Changes in fair value were recorded directly as an adjustment to current earnings through non-interest expense. Bank property held for sale represents certain branch office buildings which the Company has closed and consolidated with other existing branches or acquired through various acquisitions. The real estate was transferred out of the Bank Premises and Equipment category into Bank Property Held For Sale at the lower of amortized cost or fair value less estimated costs to sell. The fair values were based upon appraisals.

Excluding the net operating losses not subject to expiration, the Company had approximately $51,830 of net operating loss carryforwards at December 31, 2018, which will begin to expire as follows: 2027 $ 2,418 2028 1,996 2029 11,826 2030 13,681 2031 7,246 2032 6,841 2033 7,063 2035 759 $ 51,830 As a result of the enactment of the Tax Act on December 22, 2017, the Company evaluated its deferred tax assets and deferred tax liabilities to account for the future impact of lower corporate tax rates on its deferred tax assets. The reduction in the federal corporate tax rate resulted in a one-time charge to the Company’s earnings and reduction to its net deferred tax assets of approximately $ 18,575 , which was recorded in 2017. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. In performing this analysis, the Company considers all evidence currently available, both positive and negative, in determining whether based on the weight of that evidence, it is more likely than not the deferred tax asset will be realized. Based on management’s analysis, it was determined that it is more likely than not that the net deferred tax asset, net of the one-time charge mentioned above, will be realized as of December 31, 2018 and 2017. The Company and its subsidiaries are subject to U.S. federal income tax as well as income tax of the states of Florida, Georgia, Alabama, California, Colorado, North Carolina and Tennessee. CSFL Insurance Corp. files a tax return in South Carolina. The Company is no longer subject to examination by taxing authorities for the years before 2015. The Company has not recorded any material interest or penalties on its income tax liabilities for the years 2018, 2017 and 2016. A reconciliation between the actual tax expense and the “expected” tax expense, computed by applying the U.S. federal corporate rate of 21 percent for 2018 and 35 percent for 2017 and 2016 is as follows: December 31, 2018 2017 2016 “Expected” tax expense $ 41,466 $ 38,246 $ 22,488 Tax exempt interest, net (3,177 ) (4,104 ) (2,364 ) Bank owned life insurance (1,167 ) (1,251 ) (825 ) State income taxes, net of federal income tax benefits 7,827 4,077 2,347 Stock based compensation 17 40 81 Merger and acquisition related expenses 610 1,049 388 Excess tax benefit from stock based compensation (5,095 ) (3,007 ) — Revaluation of net deferred tax asset due to change in federal income tax rate — 18,575 — Other, net 543 (145 ) (205 ) $ 41,024 $ 53,480 $ 21,910 |

Banking And Thrift [Abstract] | |
Regulatory Capital Matters | (1 7 ) Regulatory Capital Matters The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. The final rules implementing Basel Committee on Banking Supervision’s capital guidelines for U.S. banks (Basel III rules) became effective for the Company on January 1, 2015 with full compliance with all of the requirements being phased in over a multi-year schedule, and fully phased in by January 1, 2019. Under these rules, banks are required to maintain a minimum CET1 ratio of 4.5 %, a minimum Tier 1 capital to risk-weighted assets of 6 %, a total risk-based capital ratio of 8 %, and a minimum leverage capital ratio of 4 %. In addition, the rules require a capital conservation buffer of up to 2.5 % above each of CET1, tier 1, and total risk-based capital which must be met for a bank to be able to pay dividends, engage in share buybacks or make discretionary bonus payments to executive management without restriction. This capital conservation buffer is being phased in over a four-year period starting on January 1, 2016. The capital conservation buffer was % in 2018 and % as of January 1, 2019 . When fully implemented, a banking organization would need to maintain a CET1 capital ratio of at least 7 %, a total Tier 1 capital ratio of at least 8.5 % and a total risk-based capital ratio of at least 10.5 %. The net unrealized gain or loss on available for sale securities is not included in computing regulatory capital. Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth in the table below) of total capital, Tier I capital and CET1 (as defined in the regulations) to risk-weighted assets. Management believes, as of December 31, 2018, that the Company and the Bank meet all capital adequacy requirements to which they are subject. As of December 31, 2018 and 2017, the most recent notifications from the Office of Comptroller of the Currency (“OCC”) categorized the Bank as “well capitalized” under the regulatory framework for prompt corrective action. To be categorized as “well capitalized,” the Bank must maintain total risk-based, Tier I risk-based, common equity Tier 1 risk-based and Tier I leverage ratios as set forth in the table. There are no conditions or events since that notification that management believes have changed the institution’s category. A summary of actual, required, and capital levels necessary for capital adequacy purposes for the Company as of December 31, 2018 and 2017, are presented in the table below.

As of December 31, 2018, the total remaining unrecognized compensation cost related to non-vested stock options was approximately $42 and will be recognized over the next 4 years. The weighted average period over which this expense is expected to be recognized is approximately 4.8 years . As of December 31, 2018, the total remaining unrecognized compensation cost related to non-vested RSAs, net of estimated forfeitures, was approximately $4,012 and will be recognized over the next 9 years. The weighted average period over which this expense is expected to be recognized is approximately 2.4 years. As of December 31, 2018, the total remaining unrecognized compensation cost related to non-vested PSUs, net of estimated forfeitures, was approximately $1,674 and will be recognized over the next 3 years. The weighted average period over which this expense is expected to be recognized is approximately 1.8 years. As of December 31, 2018 the total remaining unrecognized compensation cost related to non-vested RSUs, net of estimated forfeitures, was approximately $1,601 and will be recognized over the next 3 years. The weighted average period over which this expense is expected to be recognized is approximately 1.8 years. The Company did not grant any stock options during 2016, 2017 and 2018. However, the Company converted all outstanding Gateway stock options into CenterState options for 1,150,517 shares of common stock on the May 1, 2017 acquisition date pursuant to the Company’s agreement to acquire Gateway. The Company also converted all outstanding Sunshine and HCBF stock options into CenterState options for 590,345 and 1,621,543 shares of common stock, respectively, on the January 1, 2018 acquisition date pursuant to the Company’s respective agreements to acquire Sunshine and HCBF. The estimated fair value of options granted, or acquired in the case of Gateway, Sunshine and HCBF, during these periods were calculated as of the grant date, or the acquisition date in the case of Gateway, Sunshine and HCBF, using the Black-Scholes option-pricing model. The Company determined the expected life of the stock options using the simplified method approach allowed for plain-vanilla share options as described in SAB 107. The risk-free interest rate is based on the U.S. Treasury yield curve in effect as of the grant date. Expected volatility was determined using historical volatility. ASC 718 requires the recognition of stock-based compensation for the number of awards that are ultimately expected to vest. However, with the adoption of ASU 2016-09 in 2017, the Company made an entity-wide accounting policy election to account for forfeitures when they occur. The weighted-average estimated fair value of stock options granted, or acquired in the case of Sunshine and HCBF, during the twelve-month period ended December 31, 2018 was $14.81 per share.

In addition, the Company may also make additional contributions to the plan each year, subject to profitability and other factors, and based solely on the discretion of the Board of Directors. For the years ended December 31, 2018, 2017 and 2016, the Company’s contributions to the plan were $3,444, $2,249 and $1,849, respectively, which are included in Salary, Wages and Employee Benefits on the Consolidated Statements of Income and Comprehensive Income. The Company has since amended its 401(k) defined contribution retirement plan’s participation eligibility requirement to the first month following the date of employment effective January 1, 2019. In 2008, the Company entered into a salary continuation agreement with its then chief executive officer. Five additional Company executive officers entered into salary continuation agreements during 2010. In 2007, an additional four pre-existing salary continuation agreements with certain Valrico State Bank’s executive officers were assumed as part of the acquisition. In 2018, the Company assumed pre-existing supplemental executive retirement plan agreements pursuant to the acquisition of Charter. The plans are nonqualified deferred compensation arrangements that are designed to provide supplemental retirement income benefits to participants. The Company expensed $641, $568 and $609 for the accrual of future salary continuation benefits in 2018, 2017 and 2016, respectively. Other liabilities included salary continuation benefits payable of $7,966, $4,834 and $4,211 at December 31, 2017, 2016 and 2015, respectively. In 2007, the Company entered into deferred compensation arrangements, through Rabbi Trust agreements, with two Valrico State Bank’s executive officers pursuant to the acquisition. The Rabbi Trust asset is included in other assets, and the related deferred compensation payable is included in other liabilities. In 2018, one of the executive officers retired and received the applicable funds from the agreement. The Rabbi Trust asset and the related deferred compensation payable at December 31, 2018, 2017 and 2016 were $307, $1,761 and $1,560, respectively. Earnings from the Rabbi Trust increase the asset and increase the deferred compensation payable. Losses from the Rabbi Trust decrease the asset and decrease the deferred compensation payable. There was no net income statement effect other than the administration expenses of the Trust which approximates $5 per year. |

Commitments And Contingencies Disclosure [Abstract] | |
Credit Commitments | (2 2 ) Credit Commitments The Company has outstanding at any time a significant number of commitments to extend credit. These arrangements are subject to strict credit control assessments and each customer’s credit worthiness is evaluated on a case-by-case basis. A summary of commitments to extend credit and standby letters of credit written at December 31, 2018 and 2017, are as follows: December 31, 2018 2017 Standby letters of credit $ 28,964 $ 15,740 Available lines of credit 1,514,359 824,958 Unfunded loan commitments – fixed 153,680 140,750 Unfunded loan commitments – variable 65,880 35,814 Commitments to make loans are generally made for periods of 30 days or less. At December 31, 2018, the fixed rate loan commitments have interest rates ranging from 3.27% to 8.35% and maturities ranging from 1 year to 20 years. Because many commitments expire without being funded in whole or part, the contract amounts are not estimates of future cash flows. Credit risk represents the accounting loss that would be recognized at the reporting date if counterparties failed completely to perform as contracted. The credit risk amounts are equal to the contractual amounts, assuming that the amounts are fully advanced and that the collateral or other security is of no value. The Company’s policy is to require customers to provide collateral prior to the disbursement of approved loans. The amount of collateral obtained, if it is deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the counterparty. Collateral held varies but may include accounts receivable, inventory, real estate and income providing commercial properties. Standby letters of credit are contractual commitments issued by the Company to guarantee the performance of a customer to a third party. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. Outstanding commitments are deemed to approximate fair value due to the variable nature of the interest rates involved and the short-term nature of the commitments. |

Risks And Uncertainties [Abstract] | |
Concentrations of Credit Risk | (2 3 ) Concentrations of Credit Risk Most of the Company’s business activity is with customers located throughout Southeastern United States including Florida, Georgia and Alabama. The majority of commercial and mortgage loans are granted to customers doing business or residing in these areas. Generally, commercial loans are secured by real estate, and mortgage loans are secured by either first or second mortgages on residential or commercial property. As of December 31, 2018, substantially all of the Company’s loan portfolio was secured. Although the Company has a diversified loan portfolio, a substantial portion of its debtors’ ability to honor their contracts is dependent upon the economy of those areas listed above. The Company does not have significant exposure to any individual customer or counterparty. |

The pro-forma information for the twelve-month period ending December 31, 2018 assumes the Charter acquisition occurred at the beginning of 2017. Years ended December 31, 2018 2017 Net interest income $ 450,847 $ 421,556 Net income available to common shareholders $ 178,746 $ 96,633 EPS - basic $ 1.88 $ 1.04 EPS - diluted $ 1.85 $ 1.02 The disclosures regarding the results of operations for Community, Hometown, Platinum, Gateway, Sunshine, HCBF and Charter subsequent to their respective acquisition dates are omitted as this information is not practical to obtain.

Although the Company did not convert HCBF’s core system in the first quarter of 2018 or Charter’s core system in the third quarter of 2018, the majority of the fixed costs and purchase accounting entries were booked on the Company’s core system making it impractical to determine HCBF or Charter’s results of operation on a stand-alone basis. Announced Acquisition of National Commerce Corporation On November 23, 2018, the Company entered into a definitive agreement to acquire National Commerce Corporation (“NCC”), whereby NCC will merge with and into the Company, with the Company continuing as the surviving corporation in the merger. Immediately after the merger, the Company’s subsidiary bank and NCC’s subsidiary bank, National Bank of Commerce (“NBC”), will merge with CenterState Bank as the surviving bank. Under the terms of the agreement, each outstanding share of NCC common stock will convert into the right to receive 1.65 shares of the Company’s common stock, provided that cash in lieu of any fractional shares of CenterState common stock will be paid. The transaction was unanimously approved by the boards of directors of both companies. The transaction is expected to close in the second quarter of 2019 subject to customary closing conditions, including receipt of all applicable regulatory approvals and shareholder approval of the Company and stockholder approval of NCC. The Company’s primary reasons for the transaction are to expand its core growth markets of Orlando, Tampa, Jacksonville and Atlanta, further solidify its market share in Florida, Georgia and Alabama, expand its customer base to enhance deposit fee income and leverage operating cost through economies of scale. NCC, which is headquartered in Birmingham, Alabama, operates 37 banking locations. As of December 31, 2018, NCC reported total assets of $4,210,541, total loans of $3,317,965 and total deposits of $3,432,289. |

Derivative Instruments And Hedging Activities Disclosure [Abstract] | |
Interest Rate Swap Derivatives | (2 7 ) Interest Rate Swap Derivatives The Company enters into interest rate swaps in order to provide commercial loan clients the ability to swap from fixed to variable interest rates. Under these agreements, the Company enters into a fixed-rate loan with a client in addition to a swap agreement. This swap agreement effectively converts the client’s fixed rate loan into a variable rate. The Company then enters into a matching swap agreement with a third party dealer in order to offset its exposure on the customer swap. At years ended December 31, 2018 and 2017, the notional amount of such arrangements was $5,743,283 and $3,740,430, respectively. Due to new regulations effective in 2017, the Company pledged $28,345 and $16,991 of cash as collateral to the third party dealers at December 31, 2018 and 2017, respectively. At December 31, 2017, in addition to the cash collateral, investment securities with a fair value of $19,048 was pledged. As the interest rate swaps with the clients and third parties are not designated as hedges under ASC 815, changes in market values are reported in earnings. Summary information about the derivative instruments is as follows: 2018 2017 Notional amount $ 5,743,283 $ 3,740,430 Weighted average pay rate on interest-rate swaps 3.64 % 3.00 % Weighted average receive rate on interest rate swaps 3.64 % 3.00 % Weighted average maturity (years) 11 11 Fair value of interest rate swap derivatives (asset) 92,475 42,480 Fair value of interest rate swap derivatives (liability) 92,892 43,259 |

Revenue From Contract With Customer [Abstract] | |
Revenue from Contracts with Customers | (2 8 ) Revenue from Contracts with Customers On January 1, 2018, the Company adopted 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”). ASU 2014-09 implements a common revenue standard that clarifies the principles for recognizing revenue. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract and (v) recognize revenue when (or as) the entity satisfies a performance obligation. The There are two reasons ASU 2014-09 did not have an impact to the Company. First, the majority of revenues are interest earned and gain on sales of loans, investment securities and other financial instruments, all of which are unaffected as they are outside the scope of ASU 2014-09. Secondly, the Company’s non-interest income revenue streams such as service charges on deposits, treasury management fees, wealth advisory fees, fixed income sales, and correspondent bank fees, are all within the scope of ASU 2014-09. However, ASC Topic 606 focuses on revenues from contracts earned over time, but all of these in-scope noninterest income revenue streams are governed by agreements that do not have an enforceable, contractual term. Given the cancellable-at-will structure, ASC Topic 606 views these contracts as agreements-at-will without a defined term, the revenues of which are immediately recognized. The revenue recognition timing is identical compared to previous revenue recognition standards. All of the Company’s revenue from contracts with customers in the scope of ASC 606 is recognized within Non-Interest Income. ASU 2014-09 requires disclosure of sufficient information to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. A description of the Company’s revenue streams accounted for under ASC 606 as well as an explanation of why they are not impacted are as follows: Revenues by Operating Segment/Line of Business Correspondent Banking Capital Markets Revenue - Fixed Income Sales The company earns commission revenues from the sale of fixed income securities to institutional investors. These revenues are earned and collected at each individual sale, and the sale is the sole performance obligation. There are no minimum orders or future performance obligations or deferred recognition requirements. Other Correspondent Banking Related Revenue The company earns revenues from a variety of services to other financial institutions including but not limited to correspondent banking, cash and clearing, safekeeping, wire transfers, international services, bond accounting, and others. Fixed income sales are discussed separately. While there is a significant variety of a la carte services, all (except fixed income sales) are either billed as incurred or are subject to monthly billing, at which point the performance obligation have been fulfilled. Even though a Correspondent agreement may provide for services over an indefinite period of time, the customer is free to end the agreement at will without penalty. This structure is viewed as an at-will agreement under ASC 606, the revenues of which are recognized immediately. Service Charges on Deposit Accounts The Company earns fees from its deposit customers for transaction-based, account maintenance, and overdraft services. Transaction-based fees, which include but are not limited to: services such as ATM use fees, stop payment charges, statement rendering, ACH fees, are recognized at the time the transaction is executed as that is the point in time the Company fulfills the customer’s request. Maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which the Company satisfies the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are withdrawn from the customer’s account balance. Wealth Management Related Revenue - Treasury Management The Company earns fees for Treasury Management products and services which include but are not limited to online cash management, remote deposit capture, positive pay, and lockboxes. Similar to the above service charges on deposit accounts above, these fees are also recognized at either the time the transaction or at the end of the month in the case where service obligations are provided over the course of each month. Even though a customer’s Treasury Management agreement may provide for services over an indefinite period of time, the customer is free to end the agreement at will without penalty. This structure is viewed as an at-will agreement under ASC 606, the revenues of which are recognized immediately. Wealth Management Related Revenue - Wealth Management & Advisory The Company has contracted with a third party to provide wealth management and investment brokerage services on behalf of the Company. All fees earned by the Company from Wealth Management and Advisory activities are in the form of a revenue sharing agreement. The Company acts as agent in this agreement, and as such, ASC 606 deems the third party to be the customer of the Company as opposed to those individual and entities receiving the wealth advisory services. The agreed-upon portion of revenues generated by the third party for services provided other entities and individuals are owed and remitted to the Company at the end of each month, at which time all performance obligations of the Company are fulfilled. Wealth Management Related Revenue - Trust The Company sold its Trust Department in December 2017. While there would have been ASC Topic 606 revenue recognition timing implications, the sale prior to December 31, 2017 removed these revenues from consideration. Trust revenues are displayed for prior periods only. Debit, Prepaid, ATM and Merchant Card Related Fees - Prepaid Cards The Company earns revenues from prepaid card interchange fees and maintenance fees. Interchange fees from cardholder transactions represent a portion of the underlying transaction value and are recognized daily, concurrently with the transaction processing services to the cardholder. Similar to fees from deposits accounts, maintenance fees are earned over the performance obligation period, after which all obligations have been fulfilled. Debit, Prepaid, ATM and Merchant Card Related Fees - Credit Cards The Company earns revenues from a revenue sharing agreement with a third party who provides credit card services for Company customers. Similar to the Wealth Management and Advisory revenue sharing agreement discussed above, the Company is the agent and the third party is the customer. The revenue sharing agreement calculates fees owed to the Company based on interchange and application amounts and levels. These share of fees are remitted to the Company each month, at which time the performance obligation is fulfilled. Debit, Prepaid, ATM and Merchant Card Related Fees - Debit Card Interchange Income The Company earns interchange fees from debit cardholder transactions through the MasterCard payment network. Interchange fees form cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. Gains/Losses on Sales of Repossessed Real Estate (“OREO”) The Company records a gain or loss from the sale of OREO when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. There are no ASC 606 implications unless the Company finances the sale of OREO. There are no instances of the Company financing the sale of one of its OREO properties as of September 30, 2018. Contract Balances The Contract Balances disclosure requirement is not relevant, as no revenues are earned over time that would require the monitoring of contract balances. The Performance Obligations disclosure requirements call for a description of when performance obligations are satisfied, significant payment terms, nature of goods or services promised, and obligations for returns, refunds, and warranties. |

Debt securities not classified as held to maturity or trading are classified as available for sale. Debt s ecurities available for sale are carried at fair value, with unrealized holding gains and losses reported in other comprehensive income, net of tax. Interest income includes amortization of purchase premium or discount. Premiums on securities are amortized to the earliest call date. Discounts on securities are amortized on the level-yield method without anticipating prepayments, except for mortgage backed securities where prepayments are anticipated. Gains and losses on sales are recorded on the trade date and determined using the specific identification method. Securities are evaluated for other-than-temporary impairment (“OTTI”) on at least an annual basis, and more frequently when economic or market conditions warrant such an evaluation. For securities in an unrealized loss position, management considers the extent and duration of the unrealized loss, and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or it is more likely than not that it will be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: 1) OTTI related to credit loss, which must be recognized in the income statement; and 2) other-than-temporary impairment related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. |
Bond Commissions Revenue Recognition | (g) Bond commissions revenue recognition Bond sales transactions and related revenue and expenses are recorded on a settlement date basis. The effect on the financial statements of using the settlement date basis rather than the trade date basis is not material. |
Loans Held for Sale | (h) Loans held for sale Effective January 1, 2018, mortgage loans originated and intended for sale in the secondary market are carried at fair value with changes in fair value recognized in current period earning. For periods prior to December 31, 2018, mortgage loans held for sale were carried at the lower of aggregate cost or fair value, as determined by outstanding commitments from investors. Net unrealized losses, if any, are recorded as a valuation allowance and charged to earnings. Mortgage loans held for sale are generally sold with servicing rights released. Gains and losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold. |
Loans | (i) Loans Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their outstanding unpaid principal balance net of purchase premiums and discounts, deferred loan fees and costs, and an allowance for loan losses. Interest income is accrued on the unpaid principal balance. The recorded investment in a loan excludes accrued interest receivable, deferred fees, and deferred costs because they are not considered material. A loan is considered a troubled debt restructured loan based on individual facts and circumstances. A modification may include either an increase or reduction in interest rate or deferral of principal payments or both. Loans for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties, are considered troubled debt restructurings. The Company classifies troubled debt restructured loans as impaired and evaluates the need for an allowance for loan losses on a loan-by-loan basis. An allowance for loan losses is based on either the present value of estimated future cash flows or the estimated fair value of the underlying collateral. Loans retain their accruing or non-accruing status at the time of modification. Loan origination fees and the incremental direct cost of loan origination, are deferred and recognized in interest income without anticipating prepayments over the contractual life of the loans. If the loan is prepaid, the remaining unamortized fees and costs are charged or credited to interest income. Amortization ceases for non-accrual loans. A loan is moved to non-accrual status in accordance with the Company’s policy typically after 90 days of non-payment, or less than 90 days of non-payment if management determines that the full timely collection of principal and interest becomes doubtful. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on non-accrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. Non-accrual loans and loans past due 90 days still on accrual include both smaller balance homogeneous loans that are collectively evaluated for impairment and individually classified impaired loans. Single family home loans, consumer loans and smaller commercial, land, development and construction loans (less than $ 500 ) are monitored by payment history, and as such, past due payments is generally the triggering mechanism to determine non - accrual status. Larger (greater than $ 500 ) commercial, land, development and construction loans are monitored on a loan level basis, and therefore in these cases it is more likely that a loan may be placed on non - accrual status before it becomes 90 days past due. All interest accrued but not received for loans placed on non-accrual is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Non real estate consumer loans are typically charged off no later than 120 days past due. The Company, considering current information and events regarding the borrower’s ability to repay their obligations, considers a loan to be impaired when it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. When a loan is considered to be impaired, the amount of the impairment is measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, the secondary market value of the loan, or the fair value of the collateral for collateral dependent loans. Interest income on impaired loans is recognized in accordance with the Company’s non-accrual policy. Impaired loans are written down to the extent that principal is judged to be uncollectible and, in the case of impaired collateral dependent loans where repayment is expected to be provided solely by the underlying collateral and there is no other available and reliable sources of repayment, are written down to the lower of cost or collateral value less estimated selling costs. Impairment losses are included in the allowance for loan losses. Large groups of smaller balance homogeneous loans, such as consumer and residential real estate loans, are collectively evaluated for impairment, and accordingly, they are not separately identified for impairment disclosures. |
Purchased Credit-Impaired Loans | (j) Purchased credit-impaired loans As a part of business acquisitions, the Company acquires loans, some of which have shown evidence of credit deterioration since origination. These purchased credit-impaired (“PCI”) loans were determined to be credit impaired based on specific risk characteristics of the loan, including, but not limited to loans on non-accrual status, loans with insufficient cash flow, past due loans, high loan-to-value ratios, loans in process of foreclosure, or any TDR with loss potential. The Company, as a purchaser, is permitted to aggregate credit impaired loans acquired in the same fiscal quarter into one or more pools, provided that the loans have common risk characteristics. A pool is then accounted for as a single asset with a single composite interest rate and an aggregate expectation of cash flows. For the loan portfolios acquired, the Company aggregated the commercial, consumer, and residential loans into pools of loans with common risk characteristics for each institution acquired. These acquired loans were recorded at the acquisition date fair value, and after acquisition, losses are recognized through the allowance for loan losses. The Company estimates the amount and timing of expected cash flows for each acquired loan pool and the expected cash flows in excess of the amount paid is recorded as interest income over the remaining life of the loan pools. As frequently as quarter or as long as annually, the Company updates 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 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 provision for loan losses. Probable and significant increases in expected principal cash flows would first reverse any previously recorded allowance for loan losses; any remaining increases are recognized prospectively as interest income over the life of the pool. 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 over the life of the pool. 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 purchased credit impaired portfolio. |
Concentration of Credit Risk | (k) Concentration of credit risk Most of the Company’s business activity is with customers located within Southeastern United States largely in Florida, also in Alabama and Georgia. Therefore, the Company’s exposure to credit risk is significantly affected by changes in the economy and the real estate market within Southeast, primarily in Florida. |
Allowance for Loan Losses | (l) Allowance for loan losses The allowance for loan losses is a valuation allowance for probable incurred credit losses. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Management estimates the allowance balance required using past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, economic conditions, and other factors. Allocations of the allowance may be made for specific loans, but the entire allowance is available for any loan that, in management’s judgment, should be charged-off. The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. The general component covers loans that are not individually classified as impaired and is based on historical loss experience adjusted for current factors. A loan is impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. Loans, for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties, are considered troubled debt restructurings and classified as impaired. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. If a loan is impaired, a portion of the allowance is allocated so that the loan is reported, net, at the present value of estimated future cash flows using the loan’s existing rate or at the fair value of collateral if repayment is expected solely from the collateral. Commercial, commercial real estate, land, acquisition and development, and construction loans over $500 are individually evaluated for impairment. Large groups of smaller balance homogeneous loans, such as consumer and residential real estate loans, are collectively evaluated for impairment, and accordingly, they are not separately identified for impairment disclosures. Troubled debt restructurings are separately identified for impairment disclosures and are measured at the present value of estimated future cash flows using the loan’s effective rate. If a troubled debt restructuring is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of the collateral. For troubled debt restructurings that subsequently default, the Company determines the amount of reserve in accordance with the accounting policy for the allowance for loan losses. The general component covers non-impaired loans and is based on historical loss experience adjusted for current factors. The historical loss experience is determined by portfolio segment and is based on the actual loss history experienced by the Company over the most recent two years. The portfolio segments identified by the Company are residential loans, commercial real estate loans, construction and land development loans, commercial and industrial and consumer and other. This actual loss experience is supplemented with other economic factors based on the risks present for each portfolio segment. These economic factors include consideration of the following: levels of and trends in delinquencies and impaired loans; volume and severity of adversely classified or graded loans; levels of and trends in charge-offs and recoveries; trends in volume and terms of loans; effects of any changes in risk selection and underwriting standards; other changes in lending policies, procedures, and practices; experience, ability, and depth of lending management and other relevant staff; national and local economic trends and conditions; industry conditions; and effects of changes in credit concentrations. The Company segregates and evaluates its loan portfolio through the five portfolio segments: residential real estate, commercial real estate, land/ land development/construction, commercial and consumer/other. Residential real estate loans are a mixture of fixed rate and adjustable rate residential mortgage loans, including first mortgages, second mortgages or home equity lines of credit. As a policy, the Company holds adjustable rate loans and sells a portion of its fixed rate loan originations into the secondary market. Changes in interest rates or market conditions may impact a borrower’s ability to meet contractual principal and interest payments. Residential real estate loans are secured by real property. Commercial real estate loans include loans secured by office buildings, warehouses, retail stores and other property located in or near our markets. These loans are originated based on the borrower’s ability to service the debt and secondarily based on the fair value of the underlying collateral. Land/land development/construction loans include residential and commercial real estate loans and include a mixture of owner occupied and non-owner occupied. The majority of the loans in this category are land related, either undeveloped land, land held for development, residential building lots and commercial building lots. Generally the terms are three to five years, with a potential for renewal at maturity. Commercial loans consist of small-to medium-sized businesses including professional associations, medical services, retail trade, transportation, wholesale trade, manufacturing and tourism. Commercial loans are derived from our market areas and underwritten based on the borrower’s ability to service debt from the business’s underlying cash flows. As a general practice, we obtain collateral such as inventory, accounts receivable, equipment or other assets although such loans may be uncollateralized but guaranteed. Consumer and other loans include automobiles, boats, mobile homes without land, or uncollateralized but personally guaranteed loans. These loans are originated based primarily on credit scores, debt-to-income ratios and loan-to-value ratios. The Company evaluates the loans acquired from the Gulfstream, First Southern, Community Bank, First National, Platinum and Gateway acquisitions that were not PCI loans as individual loan portfolio segments. The Company considered the levels of and trends in non-performing loans, past-due loans, adverse loan grade classification changes, historical loss rates, environmental factors and impaired loans in arriving at its estimate. The general loan loss allowance recorded for these performing loans acquired from Gulfstream is allocated between the five portfolio segments described above in Note 5. |
Transfer of Financial Assets | (m) Transfer of financial assets Transfers of financial assets are accounted for as sales, when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Company, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. |
Other Repossessed Real Estate Owned | (n) Other repossessed real estate owned Assets acquired through or instead of loan foreclosure are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. If fair value declines subsequent to foreclosure, a valuation allowance is recorded through expense. Operating costs after acquisition are expensed. Repossessed real estate is included in other repossessed real estate owned and other repossessed assets other than real estate is included in Prepaid Expenses and Other Assets in the Consolidated Balance Sheets. |
Premises and Equipment | (o) Premises and equipment Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation. Depreciation is provided on a straight-line basis over the estimated useful lives of the related assets. Buildings are depreciated over a 39 year period, and furniture, fixtures and equipment are depreciated over their related useful life (3 to 15 years). Leasehold improvements are depreciated over the shorter of their useful lives or the term of the lease. Major renewals and betterments of property are capitalized; maintenance, repairs, and minor renewals and betterments are expensed in the period incurred. Upon retirement or other disposition of the asset, the asset cost and related accumulated depreciation are removed from the accounts, and gains or losses are included in income. |
Software Costs | (p) Software costs Costs of software developed for internal use, such as those related to software licenses, programming, testing, configuration, direct materials and integration, are capitalized and included in premises and equipment. Included in the capitalized costs are those costs related to both our personnel and third party consultants involved in the software development and installation. Once placed in service, the capitalized asset is amortized on a straight-line basis over its estimated useful life, generally three to five years. Capitalized costs of software developed for internal use are reviewed periodically for impairment. |
Federal Home Loan Bank (FHLB), Federal Reserve Bank (FRB) and Other Stock | (q) Federal Home Loan Bank (FHLB), Federal Reserve Bank (FRB) and other stock The Company’s subsidiary bank is a member of the FHLB and FRB system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB, FRB and other stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income. |
Bank Owned Life Insurance (BOLI) | (r) Bank owned life insurance (BOLI) The Company, through its subsidiary bank, has purchased life insurance policies on certain key executives or acquired through various bank acquisitions. Bank owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement. |
Goodwill and Other Intangible Assets | (s) Goodwill and other intangible assets Goodwill resulting from business combinations prior to January 1, 2009 represents the excess of the purchase price over the fair value of the net assets of businesses acquired. Goodwill resulting from business combinations after January 1, 2009, is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually. The Company has selected November 30 as the date to perform the annual impairment test. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Goodwill is the only intangible asset with an indefinite life on the Company’s balance sheet. The core deposit intangibles are intangible assets arising from either whole bank acquisitions or branch acquisitions. They are initially measured at fair value and then amortized over a ten-year period on an accelerated basis using the projected decay rates of the underlying core deposits. As a part of normal business operations, the Company originates residential mortgage loans that have been pre-approved by secondary investors. The terms of the loans are set by the secondary investors, and the purchase price that the investor will pay for the loan is agreed to prior to the commitment of the loan by the Company. Generally within three weeks after funding, the loans are transferred to the investor in accordance with the agreed-upon terms. The Company records gains from the sale of these loans on the settlement date of the sale equal to the difference between the proceeds received and the carrying amount of the loan. The gain generally represents the portion of the proceeds attributed to servicing release premiums received from the investors and the realization of origination fees received from borrowers which were deferred as part of the carrying amount of the loan. Between the initial funding of the loans by the Company and the subsequent reimbursement by the investors, the Company carries the loans on its balance sheet at the lower of cost or market. The fair value of the underlying commitment is not material to the Consolidated Financial Statements. The standard structure of mortgage loan sales provides for the Company to retain a portion of the cash flow from the interest payments received on the loan. Fees for servicing loans for investors are based on the outstanding principal balance of the loans serviced and are recognized as income when earned. This cash flow is commonly known as a servicing spread. The servicing spread is recognized as a servicing asset to the extent the spread exceeds adequate compensation for the servicing function and recorded as a component of Other Intangible Assets in the Consolidated Balance Sheets. The fair value of the servicing asset is measured on a recurring basis at the present value of future cash flows using market-based discount assumptions. The future cash flows for each asset are based on their unique characteristics and market-based assumptions for prepayment speeds, default and voluntary prepayments. Adjustments to fair value are recorded as a component of Mortgage Banking Revenue. The value of our servicing portfolio is periodically independently evaluated. |
FDIC Indemnification Asset | (t) FDIC Indemnification Asset The FDIC Indemnification Asset represented the estimated amounts due from the FDIC pursuant to the Loss Share Agreements related to the acquisitions of the three failed banks acquired in 2010, two in 2012 and assumed two additional pursuant to the Company’s 2014 acquisition of First Southern. At acquisition, the FDIC Indemnification Asset represented the discounted value of the FDIC’s reimbursed portion of the estimated losses the Company expects to realize on the loans and other real estate (“Covered Assets”) acquired as a result of the acquisitions. The range of discount rates used on the FDIC Indemnification Asset was 1.21% to 4.53%. As losses were realized on Covered Assets, the portion that the FDIC paid the Company in cash for principal and up to 90 days of interest reduced the FDIC Indemnification Asset. On a quarterly basis, the Company evaluated the FDIC Indemnification Asset to determine if the estimated losses on Covered Assets supported the amount recorded as the FDIC Indemnification Asset. Income accretion was recognized during the loss share period. If the expectation of future losses declined, the income accretion was reduced prospectively over the lesser of the term of the loss share agreement and the estimated remaining life of the Covered Asset. On February 3, 2016, the FDIC bought out the remaining FDIC loss share agreements. As such, the FDIC indemnification asset was written-off effectively accelerating all future FDIC indemnification asset amortization expense as well as ending any future FDIC indemnification income. |
Loan Commitments and Related Financial Instruments | (u) Loan commitments and related financial instruments Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded. |
Stock-Based Compensation | (v) Stock-based compensation Compensation cost is recognized for stock options and restricted stock awards issued to employees, based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the date of grant is used for restricted stock awards. During 2014 the Company initiated a Long-Term Incentive Plan which included Performance Share Units (“PSUs”). The Monte-Carlo Simulation model was used to estimate fair value of the PSUs at the grant date. Compensation cost is recognized over the required service period, generally defined as the vesting period. |
Income Taxes | (w) Income taxes Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. The Company recognizes interest and/or penalties related to income tax matters in other expenses. On December 22, 2017, the U.S. federal government enacted a tax bill, H.R1 (“Tax Act”) which reduced the federal corporate tax rates effective for fiscal year 2018. As a result of this new tax bill, the Company evaluated its deferred tax assets and deferred tax liabilities to account for the future impact of lower corporate tax rates on its deferred tax assets. The reduction in the federal corporate tax rate resulted in a one-time charge to the Company’s 2017 earnings and reduction to its net deferred tax assets. See Note 14 for more details regarding Income Taxes. |
Retirement Plans | (x) Retirement plans Employee 401(k) plan expense is the amount of matching contributions. Deferred compensation and supplemental retirement plan expense allocates the benefits over years of service. |
Marketing and Advertising Costs | (y) Marketing and advertising costs Marketing and advertising costs are expensed as incurred. |
Earnings Per Common Share | (z) Basic earnings per common share is net income divided by the weighted average number of common shares outstanding during the period. All outstanding unvested share-based payment awards that contain rights to nonforfeitable dividends are considered participating securities for this calculation. Diluted earnings per common share includes the dilutive effect of additional potential common shares issuable under stock options and unvested restricted stock awards where shares are not issued until vested. Earnings and dividends per share are restated for all stock splits and stock dividends through the date of issuance of the financial statements. |
Comprehensive Income | (aa) Comprehensive income Comprehensive income consists of net income and other comprehensive income. Other comprehensive income includes unrealized gains and losses on securities available for sale, which are also recognized as separate components of shareholders’ equity. |
Loss Contingencies | (ab) Loss contingencies Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there now are such matters that will have a material effect on the financial statements. |
Restrictions on Cash | (ac) Restrictions on cash Cash on hand or on deposit with the Federal Reserve Bank is generally required to meet regulatory reserve and clearing requirements. Cash is required to be pledged as collateral to the third party dealers for the interest rate swap derivatives. |
Dividend Restriction | (ad) Dividend restriction Banking regulations require maintaining certain capital levels and may limit the dividends paid by the bank to the holding company or by the holding company to shareholders. |
Fair Value of Financial Instruments | (ae) Fair value of financial instruments Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in a separate note. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect the estimates. |
Segment Reporting | (af) Segment reporting The Company’s correspondent banking and capital markets division represents a distinct reportable segment which differs from the Company’s primary business of commercial and retail banking in Florida, Georgia and Alabama. Accordingly, a reconciliation of reportable segment revenues, expenses and profit to the Company’s consolidated total has been presented in Note 25. |
Derivatives | (ag) Derivatives The Company enters into interest rate swaps in order to provide commercial loan clients the ability to swap from fixed to variable interest rates. Under these agreements, the Company enters into a fixed-rate loan with a client in addition to a swap agreement. This swap agreement effectively converts the client’s fixed rate loan into a variable rate. The Company then enters into a matching swap agreement with a third party dealer in order to offset its exposure on the customer swap. The Company does not use derivatives for trading purposes. The derivative transactions are considered instruments with no hedging designation, otherwise known as stand-alone derivatives. Changes in the fair value of the derivatives are reported currently in earnings. |
Reclassifications | (ah) Reclassifications Some items in the prior year financial statements were reclassified to conform to the current presentation. Reclassifications had no effect on prior years’ net income or shareholders’ equity. |
Effect of New Pronouncements | (ai ) Effect of new pronouncements In January 2016, the FASB issued ASU No. 2016-01, "Recognition and Measurement of Financial Assets and Financial Liabilities." This ASU addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments by making targeted improvements to GAAP as follows: (1) require equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. However, an entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer; (2) simplify the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. When a qualitative assessment indicates that impairment exists, an entity is required to measure the investment at fair value; ( 3 ) eliminate the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet; ( 4 ) require public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; ( ( 5 ) require separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet or the accompanying Notes to the Financial Statements ; and ( 6 ) clarify that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. ASU No. 2016-01 is effective for interim and annual reporting periods beginning after December 15, 2017. Starting with the first quarter of 2018, the Company began using an exit price notion when measuring the fair value of its loan portfolio, excluding loans held for sale, for disclosure purposes. The new guidance did not impact the Company's Consolidated Financial Statements. In February 2016, the FASB issued ASU No. 2016-02, "Leases." Under this guidance, lessees will be required to recognize the following for all leases (with the exception of short-term leases): 1) a lease liability, which is the present value of a lessee's obligation to make lease payments, and 2) a right-of-use asset, which is an asset that represents the lessee's right to use, or control the use of, a specified asset for the lease term. Lessor accounting under the new guidance remains largely unchanged as it is substantially equivalent to existing guidance for sales-type leases, direct financing leases, and operating leases. Leveraged leases have been eliminated, although lessors can continue to account for existing leveraged leases using the current accounting guidance. Other limited changes were made to align lessor accounting with the lessee accounting model and the new revenue recognition standard. All entities will classify leases to determine how to recognize lease-related revenue and expense. Quantitative and qualitative disclosures will be required by lessees and lessors to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The intention is to require enough information to supplement the amounts recorded in the financial statements so that users can understand more about the nature of an entity’s leasing activities. ASU No. 2016-02 is effective for interim and annual reporting periods beginning after December 15, 2018; early adoption is permitted. All entities are required to use a modified retrospective approach for leases. Management is electing the effective date method of the modified retrospective transition approach. Under the effective date method, all lease accounting transitions to ASC 842 as of January 1, 2019 through a one-time recognition of previously off-balance sheet leases as well as a one-time offset to retained earnings for measurement differences. Under the effective date transition approach, all comparative periods presented prior to January 1, 2019 will remain in accordance with legacy lease accounting of ASC 840. The Company leases certain properties and equipment under operating leases that will result in the recognition of right-of-use lease assets of approximately $21 million and lease liabilities of approximately $24 million In June 2016, the FASB issued ASU No. 2016-13, “Measurement of Credit Losses on Financial Instruments.” This ASU significantly changes how entities will measure credit losses for most financial assets and certain other instruments that aren’t measured at fair value through net income. In issuing the standard, the FASB is responding to criticism that today’s guidance delays recognition of credit losses. The standard will replace today’s “incurred loss” approach with an “expected loss” model. The new model, referred to as the current expected credit loss (“CECL”) model, will apply to: (1) financial assets subject to credit losses and measured at amortized cost, and (2) certain off-balance sheet credit exposures. This includes, but is not limited to, loans, leases, held-to-maturity securities, loan commitments, and financial guarantees. The CECL model does not apply to available-for-sale (“AFS”) debt securities. For AFS debt securities with unrealized losses, entities will measure credit losses in a manner similar to what they do today, except that the losses will be recognized as allowances rather than reductions in the amortized cost of the securities. As a result, entities will recognize improvements to estimated credit losses immediately in earnings rather than as interest income over time, as they do today. The ASU also simplifies the accounting model for purchased credit-impaired debt securities and loans. ASU 2016-13 also expands the disclosure requirements regarding an entity’s assumptions, models, and methods for estimating the allowance for loan and lease losses. In addition, entities will need to disclose the amortized cost balance for each class of financial asset by credit quality indicator, disaggregated by the year of origination. ASU No. 2016-13 is effective for interim and annual reporting periods beginning after December 15, 2019; early adoption is permitted for interim and annual reporting periods beginning after December 15, 2018. Entities will apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (i.e., modified retrospective approach). The Company formed a CECL committee to assist with the implementation process . It has selected a third-party vendor to assist with the allowance for loan loss methodology as well as advisory services related to the implementation of the amendments of ASU 2016-13. The Company continues to work with the third-party vendor to develop the CECL model and evaluate the impact to the Company’s Consolidated Financial Statements. The standard will add new disclosures related to factors that influenced management’s estimate, including current expected credit losses, the changes in those factors, and reasons for the changes as well as the method applied to revert to historical credit loss experience, and the Company expects to recognize a one-time cumulative effect adjustment to the allowance for loan losses as of the beginning of the first reporting period in which the new standard is effective, but has not yet determined the magnitude of any such one-time adjustment or the overall impact on the Company’s Financial Statements . In January 2017, the FASB issued ASU No. 2017-04, “Simplifying the Test for Goodwill Impairment,” to simplify how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. In In May 2017, the FASB issued ASU 2017-09, “Scope of Modification Accounting,” to provide clarity and reduce both (1) diversity in practice and (2) cost and complexity when applying the guidance in Topic 718, “Compensation—Stock Compensation,” to a change to the terms or conditions of a share-based payment award. The amendments in this update provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. An entity should account for the effects of a modification unless all the following are met: (1) the fair value (or calculated value or intrinsic value, if such an alternative measurement method is used) of the modified award is the same as the fair value (or calculated value or intrinsic value, if such an alternative measurement method is used) of the original award immediately before the original award is modified. If the modification does not affect any of the inputs to the valuation technique that the entity uses to value the award, the entity is not required to estimate the value immediately before and after the modification; (2) the vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified; (3) the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified. The current disclosure requirements in Topic 718 apply regardless of whether an entity is required to apply modification accounting under the amendments in this update . In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities.” The amendments in this update more closely align the results of cash flow and fair value hedge accounting with risk management activities through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results in the financial statements. The amendments address specific limitations in current GAAP by expanding hedge accounting for both nonfinancial and financial risk components and by refining the measurement of hedge results to better reflect an entity’s hedging strategies. Thus, the amendments will enable an entity to report more faithfully the economic results of hedging activities for certain fair value and cash flow hedges and will avoid mismatches in earnings by allowing for greater precision when measuring changes in fair value of the hedged item for certain fair value hedges. Additionally, by aligning the timing of recognition of hedge results with the earnings effect of the hedged item for cash flow and net investment hedges, and by including the earnings effect of the hedging instrument in the same income statement line item in which the earnings effect of the hedged item is presented, the results of an entity’s hedging program and the cost of executing that program will be more visible to users of financial statements. Overall, those amendments are an improvement because an entity’s financial statements will reflect more accurately and comprehensively the intent and outcome of its hedging strategies. The tabular disclosure related to effects on the income statement of fair value and cash flow hedges and the disclosure of cumulative basis adjustments for fair value hedges provide users with a more complete picture of the effect of hedge accounting on an entity’s income statement and balance sheet. When considered together, the amendments to presentation and disclosures are an improvement because they will provide users with more decision-useful information about the effect of an entity’s risk management activities on the financial statements. Additionally, the amendments in this Update should ease the operational burden of applying hedge accounting by allowing more time to prepare hedge documentation and, allowing effectiveness assessments to be performed on a qualitative basis after hedge inception. For public business entities, the amendments in this update become effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted, including adoption in an interim period. All transition requirements and elections should be applied to hedging relationships existing (that is, hedging relationships in which the hedging instrument has not expired, been sold, terminated, or exercised or the entity has not removed the designation of the hedging relationship) on the date of adoption. The effect of adoption should be reflected as of the beginning of the fiscal year of adoption (that is, the initial application date). For cash flow and net investment hedges existing at the date of adoption, an entity should apply a cumulative-effect adjustment related to eliminating the separate measurement of ineffectiveness to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings as of the beginning of the fiscal year that an entity adopts the amendments in this Update. The amended presentation and disclosure guidance is required only prospectively. The Company evaluated the impact of adopting the new guidance on the Consolidated Financial Statements, but it does not have a material impact. In February 2018, the FASB issued ASU 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. On December 22, 2017, the U.S. federal government enacted the Tax Act. Stakeholders in the banking and insurance industries expressed concern about the guidance in current generally accepted accounting principles (GAAP) that requires deferred tax liabilities and assets to be adjusted for the effect of a change in tax laws or rates with the effect included in income from continuing operations in the reporting period that includes the enactment date. That guidance is applicable even in situations in which the related income tax effects of items in accumulated other comprehensive income were originally recognized in other comprehensive income (rather than in income from continuing operations). Those stakeholders asserted that because the adjustment of deferred taxes due to the reduction of the historical corporate income tax rate to the newly enacted corporate income tax rate is required to be included in income from continuing operations, the tax effects of items within accumulated other comprehensive income (referred to as stranded tax effects) do not reflect the appropriate tax rate. The amendments in this update affect any entity that is required to apply the provisions of Topic 220, Income Statement—Reporting Comprehensive Income, and has items of other comprehensive income for which the related tax effects are presented in other comprehensive income as required by GAAP. The amendments in this update allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Act. Consequently, the amendments eliminate the stranded tax effects resulting from the Tax Act and will improve the usefulness of information reported to financial statement users. The amendments only relate to the reclassification of the income tax effects of the Tax Act; the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not affected. The amendments in this update also require certain disclosures about stranded tax effects. The amendments in this update are effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. The amendments in this update should be applied either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Act is recognized. The Company early adopted this update which resulted in a reclassification of $1,241 In June 2018, the FASB issued ASU No. 2018-07, “Compensation – Stock Compensation (Topic 718) - Improvements to Nonemployee Share-Based Payment Accounting,” to include share based payment transactions for acquiring goods and services from nonemployees. An entity should apply the requirements of Topic 718 to nonemployee awards except for specific guidance on inputs to an option pricing model and the attribution of cost (that is, the period of time over which share-based payment awards vest and the pattern of cost recognition over that period). The amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The amendments also clarify that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The amendments in this update become effective for annual periods and interim periods within those annual periods beginning after December 15, 2018 but no earlier than an entity’s adoption date of Topic 606. The Company evaluated the impact of adopting the new guidance on the Consolidated Financial Statements, but it does not have a material impact. In August 2018, the FASB issued ASU No. 2018-13, “Fair Value Measurement (Topic 820) - Changes to the Disclosure Requirements for Fair Value Measurement,” to modify the disclosure requirements on fair value measurements in Topic 820 based on the concepts in the Concepts Statement, including the consideration of costs and benefits. The following disclosure requirements were removed from Topic 820: (1) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy; (2) the policy for timing of transfers between levels; (3) the valuation processes for Level 3 fair value measurements; and (4) for nonpublic entities, the changes in unrealized gains and losses for the period included in earnings for recurring Level 3 fair value measurements held at the end of the reporting period. The following disclosure requirements were modified in Topic 820: (1) in lieu of a rollforward for Level 3 fair value measurements, a nonpublic entity is required to disclose transfers into and out of Level 3 of the fair value hierarchy and purchases and issues of Level 3 assets and liabilities; (2) for investments in certain entities that calculate net asset value, an entity is required to disclose the timing of liquidation of an investee’s assets and the date when restrictions from redemption might lapse only if the investee has communicated the timing to the entity or announced the timing publicly; and (3) the amendments clarify that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date. The following disclosure requirements were added to Topic 820: (1) the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period; (2) the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. For certain unobservable inputs, an entity may disclose other quantitative information (such as the median or arithmetic average) in lieu of the weighted average if the entity determines that other quantitative information would be a more reasonable and rational method to reflect the distribution of unobservable inputs used to develop Level 3 fair value measurements. The amendments in this update are effective for annual periods and interim periods within those annual periods beginning after December 15, 2019. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted upon issuance of this update. An entity is permitted to early adopt any removed or modified disclosures upon issuance of this update and delay adoption of the additional disclosures until their effective date. The Company is currently evaluating the impact of adopting the new guidance on the Consolidated Financial Statements, but it is not expected to have a material impact. |
