Basis of Presentation	Note 1 — Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and disclosures required by accounting principles generally accepted in the United States (“GAAP”) for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Certain prior period information has been reclassified to conform to the current period presentation, and these reclassifications had no impact on net income or equity as previously reported. Operating results for the three months ended March 31, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017. The condensed consolidated balance sheet at December 31, 2016 has been derived from the audited financial statements at that date but does not include all of the information and disclosures required by GAAP for complete financial statements.

Recent Accounting and Regulatory Pronouncements	Note 3 — Recent Accounting and Regulatory Pronouncements In March 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2017-08, Receivables-Nonrefundable Fees and Other Cost (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities; (“ASU 2017-08”). ASU 2017-08 shortens the amortization period of the premium for certain callable debt securities, from the contractual maturity date to the earliest call date. The amendments do not require an accounting change for securities held at a discount; an entity will continue to amortize to the contractual maturity date the discount related to callable debt securities. The amendments apply to the amortization of premiums on callable debt securities with explicit, noncontingent call features that are callable at fixed prices on preset dates. For public business entities, ASU 2017-08 is effective in fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. For entities other than public business entities, the amendments are effective in fiscal years beginning after December 15, 2019 and in interim periods in fiscal years beginning after December 15, 2020. Early adoption is permitted for all entities, including in an interim period. The amendments should be applied on a modified retrospective basis, with a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the amendments are adopted. The Company has determined that this guidance will not have a material impact on the Company’s consolidated financial statements. In March 2017, the FASB issued ASU No. 2017-07, Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost; (“ASU 2017-07”). ASU 2017-07 applies to any employer that sponsors a defined benefit pension plan, other postretirement benefit plan, or other types of benefits accounted for under Topic 715. The amendments require that an employer disaggregate the service cost component from the other components of net benefit cost, as follows (1) service cost must be presented in the same line item(s) as other employee compensation costs. These costs are generally included within income from continuing operations, but in some cases may be eligible for capitalization, (2) all other components of net benefit cost must be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented, (3) the amendments permit capitalizing only the service cost component of net benefit cost, assuming such costs meet the criteria required for capitalization by other U.S. GAAP , rather than total net benefit cost which has been permitted under prior GAAP. The guidance is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those years. The amendments should be adopted prospectively and allows a practical expedient that permits an employer to use the amounts disclosed in its pension and other postretirement benefit plan note for the prior periods to apply the retrospective presentation requirements. The Company has determined that this guidance will not have a material impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangible-Goodwill and other (Topic 350): Simplifying the Test for Goodwill Impairment; (“ASU 2017-04”). ASU 2017-04 simplifies the accounting for goodwill impairment for all entities by requiring impairment charges to be based on the first step in today’s two-step impairment test under Accounting Standards Codification (ASC) 350 and eliminating Step 2 from the goodwill impairment test. As amended, the goodwill impairment test will consist of one step comparing the fair value of a reporting unit with its carrying amount. An entity should recognize a goodwill impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. The guidance is effective for public business entities for fiscal years beginning after December 15, 2019, and interim periods within those years. The amendments should be adopted prospectively and early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company has determined that this guidance is not expected to have a material impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-03, Accounting Changes and Error Corrections (Topic 250) and Investments-Equity Method and Joint Ventures (Topic 323); (“ASU 2017-03”). ASU 2017-03 amends the Codification for SEC staff announcements made at two Emerging Issues Task Force (EITF) meetings. At the September 2016 meeting, the SEC staff expressed its expectations about the extent of disclosures registrants should make about the effects of the new FASB guidance (including any amendments issued prior to adoption) on revenue (ASU 2014-09), leases (ASU 2016-02) and credit losses on financial instruments (ASU 2016-13) in accordance with SAB Topic 11.M. That Topic requires registrants to disclose the effect that recently issued accounting standards will have on their financial statements when adopted in a future period. ASU 2017-03 incorporates these SEC staff views into ASC 250 and adds references to that guidance in the transition paragraphs of each of the three new standards. The ASU also conforms ASC 323-740-S99-2, which describes the SEC staff’s views on accounting for investments in qualified affordable housing projects, to the guidance issued in ASU 2014-01. The Company adopted this standard in the fourth quarter of 2016 and will continue to refine its disclosures around the standard. The Company determined that this guidance did not have a material impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business; (“ASU 2017-01”). ASU 2017-01 requires an entity to evaluate if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets; if so, the set of transferred assets and activities is not a business. The guidance also requires a business to include at least one substantive process and narrows the definition of outputs by more closely aligning it with how outputs are described in ASC 606. The guidance is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those years. Early adoption is permitted. The Company has determined that this guidance will not have a material impact on the Company’s consolidated financial statements. In December 2016, the FASB issued ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers ; (“ASU 2016-20”). ASU 2016-20 updates the new revenue standard by clarifying issues that had arisen from ASU 2014-09, but does not change the core principle of the new standard. The issues addressed in this ASU include: 1) Loan guarantee fees, 2) Impairment testing of contract costs, 3) Interaction of impairment testing with guidance in other topics, 4) Provisions for losses on construction-type and production-type contracts, 5) Scope of topic 606, 6) Disclosure of remaining performance obligations, 7) Disclosure of prior-period performance obligations, 8) Contract modifications, 9) Contract asset vs. receivable, 10) Refund liability, 11) Advertising costs, 12) Fixed-odds wagering contracts in the casino industry, 13) Cost capitalization for advisors to private funds and public funds. The updated guidance is effective for interim and annual reporting periods beginning after December 15, 2017. The amendments can be applied retrospectively to each prior reporting period or retrospectively with the cumulative effect of initially applying this new guidance recognized at the date of initial application. Our revenue is comprised of net interest income on financial assets and financial liabilities, which is explicitly excluded from the scope of ASU 2014-09, and non-interest income. ASU 2016-20 and 2014-09 could require us to change how we recognize certain revenue streams within non-interest income, however, we do not expect these changes to have a significant impact on our financial statements. We continue to evaluate the impact of ASU 2016-20 and 2014-09 on our Company and expect to adopt the standard in the first quarter of 2018 with a cumulative effect adjustment to opening retained earnings, if such adjustment is deemed to be significant. In August 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-15 , Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments: (“ASU 2016-15”). ASU 2016-15 addresses eight classification issues related to the statement of cash flows: Debt prepayment or debt extinguishment costs; Settlement of zero-coupon bonds; Contingent consideration payments made after a business combination; Proceeds from the settlement of insurance claims; Proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; Distributions received from equity method investees; Beneficial interests in securitization transactions; and Separately identifiable cash flows and application of the predominance principle. The updated guidance is effective for interim and annual reporting periods beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. Entities will apply the standard's provisions using a retrospective transition method to each period presented. The Company does not believe that this guidance will have a material impact on the Company’s consolidated financial statements. In June 2016, the FASB ASU No. 2016-13 , Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments: (“ASU 2016-13”). ASU 2016-13 requires an entity to utilize a new impairment model known as the current expected credit loss ("CECL") model to estimate its lifetime "expected credit loss" and record an allowance that, when deducted from the amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. The CECL model is expected to result in earlier recognition of credit losses. ASU 2016-13 also requires new disclosures for financial assets measured at amortized cost, loans and available-for-sale debt securities. The updated guidance is effective for interim and annual reporting periods beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. 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 adopted. We have dedicated staff and resources in place evaluating the Company’s options including evaluating the appropriate model options and collecting and reviewing loan data for use in these models. The Company is currently still assessing the impact that this new guidance will have on its consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share – Based Payment Accounting; (“ASU 2016-09”). ASU 2016-09 introduces targeted amendments intended to simplify the accounting for stock compensation. Specifically, ASU 2016-09 requires all excess tax benefits and tax deficiencies (including tax benefits of dividends on share-based payment awards) to be recognized as income tax expense or benefit in the income statement. The tax effects of exercised or vested awards should be treated as discrete items in the reporting period in which they occur. An entity also should recognize excess tax benefits, and assess the need for a valuation allowance, regardless of whether the benefit reduces taxes payable in the current period. That is, off balance sheet accounting for net operating losses stemming from excess tax benefits would no longer be required and instead such net operating losses would be recognized when they arise. Existing net operating losses that are currently tracked off balance sheet would be recognized, net of a valuation allowance if required, through an adjustment to opening retained earnings in the period of adoption. Entities will no longer need to maintain and track an “APIC pool.” For public business entities, ASU 2016-09 became effective for interim and annual periods beginning after December 15, 2016 which made this ASU effective for the Company starting On January 1, 2017. During the first quarter of 2017, excess tax benefits of $735,000 were recorded against income tax expense in the income statement which previously would have been recorded against surplus on the balance sheet. In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent considerations (Reporting Revenue Gross versus Net); (“ASU 2016-08”). ASU 2016-08 updates the new revenue standard by clarifying the principal versus agent implementation guidance, but does not change the core principle of the new standard. The updates to the principal versus agent guidance: (i) require an entity to determine whether it is a principal or an agent for each distinct good or service (or a distinct bundle of goods or services) to be provided to the customer; (ii) illustrate how an entity that is a principal might apply the control principle to goods, services, or rights to services, when another party is involved in providing goods or services to a customer and (iii) Clarify that the purpose of certain specific control indicators is to support or assist in the assessment of whether an entity controls a good or service before it is transferred to the customer, provide more specific guidance on how the indicators should be considered, and clarify that their relevance will vary depending on the facts and circumstances. For public business entities, the effective date and transition requirements for these amendments are the same as the effective date and transition requirements of ASU 2014-09 which is effective for interim and annual periods beginning after December 15, 2017. The amendments can be applied retrospectively to each prior reporting period or retrospectively with the cumulative effect of initially applying this new guidance recognized at the date of initial application. Our revenue is comprised of net interest income on financial assets and financial liabilities, which is explicitly excluded from the scope of ASU 2014-09, and non-interest income. ASU 2016-08 and 2014-09 could require us to change how we recognize certain revenue streams within non-interest income, however, we do not expect these changes to have a significant impact on our financial statements. We continue to evaluate the impact of ASU 2016-08 and 2014-09 on our Company and expect to adopt the standard in the first quarter of 2018 with a cumulative effect adjustment to opening retained earnings, if such adjustment is deemed to be significant. In March 2016, the FASB issued ASU No. 2016-07, Investments – Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting; (“ASU 2016-07”). ASU 2016-07 requires an investor to initially apply the equity method of accounting from the date it qualifies for that method, i.e., the date the investor obtains significant influence over the operating and financial policies of an investee. The ASU eliminates the previous requirement to retroactively adjust the investment and record a cumulative catch up for the periods that the investment had been held, but did not qualify for the equity method of accounting. For public business entities, the amendments in ASU 2016-05 are effective for interim and annual periods beginning after December 15, 2016. The amendments should be applied prospectively upon their effective date to increases in the level of ownership interest or degree of influence that result in the adoption of the equity method. ASU 2016-07 became effective for the Company on January 1, 2017 and did not have a significant impact on the Company’s consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-05, Derivatives and Hedging (Topic 815): Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships (“ASU 2016-05”). ASU 2016-05 requires an entity to discontinue a designated hedging relationship in certain circumstances, including termination of the derivative hedging instrument or if the entity wishes to change any of the critical terms of the hedging relationship. ASU 2016-05 amends Topic 815 to clarify that novation of a derivative (replacing one of the parties to a derivative instrument with a new party) designated as the hedging instrument would not, in and of itself, be considered a termination of the derivative instrument or a change in critical terms requiring discontinuation of the designated hedging relationship. For public business entities, the amendments in ASU 2016-05 are effective for interim and annual periods beginning after December 15, 2016. An entity has an option to apply the amendments in ASU 2016-05 on either a prospective basis or a modified retrospective basis. ASU 2016-05 became effective for the Company on January 1, 2017 and did not have a significant impact on the Company’s consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”). ASU 2016-02 applies a right-of-use (ROU) model that requires a lessee to record, for all leases with a lease term of more than 12 months, an asset representing its right to use the underlying asset and a liability to make lease payments. For leases with a term of 12 months or less, a practical expedient is available whereby a lessee may elect, by class of underlying asset, not to recognize an ROU asset or lease liability. At inception, lessees must classify all leases as either finance or operating based on five criteria. Balance sheet recognition of finance and operating leases is similar, but the pattern of expense recognition in the income statement, as well as the effect on the statement of cash flows, differs depending on the lease classification. For public business entities, the amendments in ASU 2016-02 are effective for interim and annual periods beginning after December 15, 2018. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach which includes a number of optional practical expedients that entities may elect to apply. The Company has reviewed its outstanding lease agreements and has centrally documented the terms of its leases. The Company is currently evaluating the provisions of ASU 2016-02 in relation to its outstanding leases to determine the potential impact the new standard will have to the Company’s consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments – Overall (Subtopic 825-10); Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”). This update is intended to improve the recognition and measurement of financial instruments and it requires an entity to: (i) measure equity investments at fair value through net income, with certain exceptions; (ii) present in OCI the changes in instrument-specific credit risk for financial liabilities measured using the fair value option; (iii) present financial assets and financial liabilities by measurement category and form of financial asset; (iv) calculate the fair value of financial instruments for disclosure purposes based on an exit price and; (v) assess a valuation allowance on deferred tax assets related to unrealized losses of AFS debt securities in combination with other deferred tax assets. ASU 2016-01 also provides an election to subsequently measure certain nonmarketable equity investments at cost less any impairment and adjusted for certain observable price changes and requires a qualitative impairment assessment of such equity investments and amends certain fair value disclosure requirements. For public business entities, the amendments in ASU 2016-01 are effective for interim and annual periods beginning after December 15, 2017. An entity should apply the amendments by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity securities without readily determinable fair values (including disclosure requirements) should be applied prospectively to equity investments that exist as of the date of adoption of the ASU 2016-01. The Company is currently evaluating the provisions of ASU 2016-01 to determine the potential impact the new standard will have to the Company’s consolidated financial statements. In September 2015, FASB issued ASU No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement Period Adjustments (“ASU 2015-16”). The update simplifies the accounting for adjustments made to provisional amounts recognized in a business combination by eliminating the requirement to retrospectively account for those adjustments. For public companies, this update became effective for interim and annual periods beginning after December 15, 2015, and is to be applied prospectively. ASU 2015-16 became effective for the Company on January 1, 2016 and did not have a significant impact on the Company’s consolidated financial statements. In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. ASU 2014-15 requires management to assess a company’s ability to continue as a going concern and to provide related footnote disclosures in certain circumstances. Before this new standard, there was minimal guidance in U.S. GAAP specific to going concern. Under the new standard, disclosures are required when conditions give rise to substantial doubt about a company’s ability to continue as a going concern within one year from the financial statement issuance date. The new standard applies to all companies and is effective for the annual period ending after December 15, 2016, and all annual and interim periods thereafter. ASU 2014-15 became effective for the Company on December 31, 2016 and did not have an impact on the consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, Topic 606 (“ASU 2014-09”). The new standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In doing so, companies will need to use more judgment and make more estimates than under existing guidance. These may include identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. In August of 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers, Topic 606: Deferral of the Effective Date, deferring the effective date of ASU 2014-09 until annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. The amendments can be applied retrospectively to each prior reporting period or retrospectively with the cumulative effect of initially applying this new guidance recognized at the date of initial application. Our revenue is comprised of net interest income on financial assets and financial liabilities, which is explicitly excluded from the scope of ASU 2014-09, and non-interest income. ASU 2014-09 could require us to change how we recognize certain revenue streams within non-interest income, however, we do not expect these changes to have a significant impact on our financial statements. We continue to evaluate the impact of ASU 2014-09 on our Company and expect to adopt the standard in the first quarter of 2018 with a cumulative effect adjustment to opening retained earnings, if such adjustment is deemed to be significant.

Mergers and Acquisitions	Note 4 — Mergers and Acquisitions The following are business combinations which have occurred over the past two years: · Bank of America, N.A. (“BOA”) – August 21, 2015 – Branch acquisition which resulted in the purchase of 12 South Carolina branch locations and one Georgia branch location from BOA · Southeastern Bank Financial Corporation (“SBFC”) – January 3, 2017 Park Sterling Corporation Proposed Acquisition On April 26, 2017, South State Corporation, (“SSB”) entered into an Agreement and Plan of Merger with Park Sterling Corporation, a North Carolina corporation ("PSTB) , and a bank holding company headquartered in Charlotte, North Carolina. The Merger Agreement provides that, upon the terms and subject to the conditions set forth therein, PSTB will merge with and into SSB, with SSB as the surviving corporation in the Merger. Immediately following the Merger, PSTB's wholly owned bank subsidiary, Park Sterling Bank ("PSB"), will merge with and into the Bank, with the Bank as the surviving entity in the bank merger. At March 31, 2017, PSTB reported $3.3 billion in total assets, $2.5 billion in loans and $2.5 billion in deposits. PSTB has over 50 full service branches in North Carolina, South Carolina, Georgia and Virginia that serve individuals and businesses. Under the terms of the agreement, shareholders of Park Sterling Corporation will receive 0.14 shares of South State common stock for each share of Park Sterling common stock. The aggregate consideration, which includes “in the money” outstanding stock options (i.e., stock options for which the exercise price of the stock option is below the market price of the underlying stock), is valued at approximately $690.8 million, based on 53,112,726 shares of Park Sterling common stock outstanding as of March 31, 2017 and on South State’s April 26, 2017 closing stock price of $91.90. The transaction is subject to regulatory approvals, the affirmative vote of both SSB’s and PSTB’s shareholders, and other customary closing conditions. The transaction is expected to close during the fourth quarter of 2017. Southeastern Bank Financial Corporation Acquisition On January 3, 2017, the Company acquired all of the outstanding common stock of SBFC, of Augusta, Georgia, the bank holding company for Georgia Bank & Trust Company of Augusta (“GB&T”), in a stock transaction. SBFC common shareholders received 0.7307 shares of the Company’s common stock in exchange for each share of SBFC stock resulting in the Company issuing 4,978,338 shares of its common stock. In total, the purchase price for SBFC was $435.1 million including the value of “in the money” outstanding stock options totaling $490,000. The SBFC transaction was accounted for using the acquisition method of accounting and, accordingly, assets acquired, liabilities assumed and consideration exchanged were recorded at estimated fair value on the acquisition date. The following table presents the assets acquired and liabilities assumed as of January 3, 2017 and their initial fair value estimates, as recorded by the Company on the acquisition date: As Recorded Fair Value As Recorded by (Dollars in thousands) by SBFC Adjustments the Company Assets Cash and cash equivalents $ 72,043 $ — $ 72,043 Investment securities 591,824 (1,770) (a) 590,054 Loans held for sale 13,652 — 13,652 Loans, net of allowance and mark 1,060,618 (10,668) (b) 1,049,950 Premises and equipment 25,419 (2,212) (c) 23,207 Intangible assets 140 17,980 (d) 18,120 Other real estate owned and repossessed assets 580 (30) (e) 550 Bank owned life insurance 44,513 — 44,513 Deferred tax asset 16,247 (687) (f) 15,560 Other assets 7,545 (482) (g) 7,063 Total assets $ 1,832,581 $ 2,131 $ 1,834,712 Liabilities Deposits: Noninterest-bearing $ 262,967 $ — $ 262,967 Interest-bearing 1,257,953 — 1,257,953 Total deposits 1,520,920 — 1,520,920 Federal funds purchased and securities sold under agreements to repurchase 1,014 — 1,014 Other borrowings 110,620 (1,120) (h) 109,500 Other liabilities 19,980 5,553 (i) 25,533 Total liabilities 1,652,534 4,433 1,656,967 Net identifiable assets acquired over (under) liabilities assumed 180,047 (2,302) 177,745 Goodwill — 257,370 257,370 Net assets acquired over liabilities assumed $ 180,047 $ 255,068 $ 435,115 Consideration: South State Corporation common shares issued 4,978,338 Purchase price per share of the Company's common stock $ 87.30 Company common stock issued ($434,609) and cash exchanged for fractional shares ($16) $ 434,625 Cash paid for stock option redemptions 490 Fair value of total consideration transferred $ 435,115 Explanation of fair value adjustments (a)—Adjustment reflects marking the securities portfolio to fair value as of the acquisition date.

Consideration is given to (1) the financial condition and near-term prospects of the issuer, (2) the outlook for receiving the contractual cash flows of the investments, (3) the length of time and the extent to which the fair value has been less than cost, (4) the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value or for a debt security whether it is more-likely-than-not that the Company will be required to sell the debt security prior to recovering its fair value, and (5) the anticipated outlook for changes in the general level of interest rates. All debt securities available for sale in an unrealized loss position as of March 31, 2017 continue to perform as scheduled. All equity securities available for sale in an unrealized loss position as of March 31, 2017 continue to pay dividends. As part of the Company’s evaluation of its intent and ability to hold investments for a period of time sufficient to allow for any anticipated recovery in the market, the Company considers its investment strategy, cash flow needs, liquidity position, capital adequacy and interest rate risk position. The Company does not currently intend to sell the securities within the portfolio and it is not more-likely-than-not that the Company will be required to sell the debt securities; therefore, management does not consider these investments to be other-than-temporarily impaired at March 31, 2017. Management continues to monitor all of these securities with a high degree of scrutiny. There can be no assurance that the Company will not conclude in future periods that conditions existing at that time indicate some or all of these securities may be sold or are other than temporarily impaired, which would require a charge to earnings in such periods.

Contractual loan payments receivable, estimates of amounts not expected to be collected, other fair value adjustments and the resulting carrying values of acquired credit impaired loans as of March 31, 2017, December 31, 2016 and March 31, 2016 are as follows: March 31, December 31, March 31, (Dollars in thousands) 2017 2016 2016 Contractual principal and interest $ 812,892 $ 778,822 $ 912,010 Non-accretable difference (31,273) (17,502) (26,833) Cash flows expected to be collected 781,619 761,320 885,177 Accretable yield (149,723) (155,379) (188,863) Carrying value $ 631,896 $ 605,941 $ 696,314 Allowance for acquired loan losses $ (4,556) $ (3,395) $ (3,877) Income on acquired credit impaired loans that are not impaired at the acquisition date is recognized in the same manner as loans impaired at the acquisition date. A portion of the fair value discount on acquired non-impaired loans has been ascribed as an accretable difference that is accreted into interest income over the estimated remaining life of the loans. The remaining nonaccretable difference represents cash flows not expected to be collected. The following are changes in the carrying value of acquired credit impaired loans: Three Months Ended March 31, (Dollars in thousands) 2017 2016 Balance at beginning of period $ 602,546 $ 733,870 Fair value of acquired loans 55,850 — Net reductions for payments, foreclosures, and accretion (29,895) (41,262) Change in the allowance for loan losses on acquired loans (1,161) (171) Balance at end of period, net of allowance for loan losses on acquired loans $ 627,340 $ 692,437 The table below reflects refined accretable yield balance for acquired credit impaired loans: Three Months Ended March 31, (Dollars in thousands) 2017 2016 Balance at beginning of period $ 155,379 $ 201,538 Addition from the Southeastern acquisition 4,603 — Accretion (15,214) (20,310) Reclass of nonaccretable difference due to improvement in expected cash flows 5,062 7,270 Other changes, net (107) 365 Balance at end of period $ 149,723 $ 188,863 In the first quarter of 2017, the accretable yield balance declined by $15.2 million as loan accretion (income) was recognized. This was partially offset by improved expected cash flows of $5.1 million. Our loan loss policy adheres to generally accepted accounting principles in the United States as well as interagency guidance. The allowance for loan losses is based upon estimates made by management. We maintain an allowance for loan losses at a level that we believe is appropriate to cover estimated credit losses on individually evaluated loans that are determined to be impaired as well as estimated credit losses inherent in the remainder of our loan portfolio. Arriving at the allowance involves a high degree of management judgment and results in a range of estimated losses. We regularly evaluate the adequacy of the allowance through our internal risk rating system, outside credit review, and regulatory agency examinations to assess the quality of the loan portfolio and identify problem loans. The evaluation process also includes our analysis of current economic conditions, composition of the loan portfolio, past due and nonaccrual loans, concentrations of credit, lending policies and procedures, and historical loan loss experience. While management uses available information to recognize losses on loans, future additions to the allowance may be necessary based on, among other factors, changes in economic conditions in our markets. In addition, regulatory agencies, as an integral part of their examination process, periodically review our allowances for losses on loans. These agencies may require management to recognize additions to the allowances based on their judgments about information available to them at the time of their examination. Because of these and other factors, it is possible that the allowances for losses on loans may change. The provision for loan losses is charged to expense in an amount necessary to maintain the allowance at an appropriate level. The allowance for loan losses on non‑acquired loans consists of general and specific reserves. The general reserves are determined by applying loss percentages to the portfolio that are based on historical loss experience for each class of loans and management’s evaluation and “risk grading” of the loan portfolio. Additionally, the general economic and business conditions affecting key lending areas, credit quality trends, collateral values, loan volumes and concentrations, seasoning of the loan portfolio, the findings of internal and external credit reviews and results from external bank regulatory examinations are included in this evaluation. Currently, these adjustments are applied to the non‑acquired loan portfolio when estimating the level of reserve required. The specific reserves are determined on a loan‑by‑loan basis based on management’s evaluation of our exposure for each credit, given the current payment status of the loan and the value of any underlying collateral. These are loans classified by management as doubtful or substandard. For such loans that are also classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. Generally, the need for specific reserve is evaluated on impaired loans, and once a specific reserve is established for a loan, a charge off of that amount occurs in the quarter subsequent to the establishment of the specific reserve. Loans that are determined to be impaired are provided a specific reserve, if necessary, and are excluded from the calculation of the general reserves. Beginning with the First Financial Holdings, Inc. (“FFHI”) acquisition in 2013, the Company segregates the acquired loan portfolio into performing loans (“non‑credit impaired) and purchased credit impaired loans. The performing loans and revolving type loans are accounted for under FASB ASC 310‑20, with each loan being accounted for individually. The allowance for loan losses on these loans will be measured and recorded consistent with non‑acquired loans. The acquired credit impaired loans will follow the description in the next paragraph. In determining the acquisition date fair value of purchased loans, and in subsequent accounting, the Company generally aggregates purchased loans into pools of loans with common risk characteristics. Expected cash flows at the acquisition date in excess of the fair value of loans are recorded as interest income over the life of the loans using a level yield method if the timing and amount of the future cash flows of the pool is reasonably estimable. Subsequent to the acquisition date, increases in cash flows over those expected at the acquisition date are reclassified from the non‑accretable difference to accretable yield and recognized as interest income prospectively. Decreases in expected cash flows after the acquisition date are recognized by recording an allowance for loan losses. Management analyzes the acquired loan pools using various assessments of risk to determine an expected loss. The expected loss is derived based upon a loss given default based upon the collateral type and/or detailed review by loan officers and the probability of default that is determined based upon historical data at the loan level. All acquired loans managed by Special Asset Management are reviewed quarterly and assigned a loss given default. Acquired loans not managed by Special Asset Management are reviewed twice a year in a similar method to the Company’s originated portfolio of loans which follow review thresholds based on risk rating categories. In the fourth quarter of 2015, the Company modified its methodology to a more granular approach in determining loss given default on substandard loans with a net book balance between $100,000 and $500,000 by adjusting the loss given default to 90% of the most current collateral valuation based on appraised value. Substandard loans greater than $500,000 were individually assigned loss given defaults each quarter. Trends are reviewed in terms of accrual status, past due status, and weighted‑average grade of the loans within each of the accounting pools. In addition, the relationship between the change in the unpaid principal balance and change in the mark is assessed to correlate the directional consistency of the expected loss for each pool. Prior to the termination of our loss share agreements in June 2016, offsetting the impact of the provision established for acquired loans covered under FDIC loss share agreements, the receivable from the FDIC was adjusted to reflect the indemnified portion of the post‑acquisition exposure with a corresponding credit to the provision for loan losses. On June 23, 2016, the Bank entered into an early termination agreement with the FDIC with respect to all of its outstanding loss share agreements. The loss share agreements were entered into with the FDIC in 2009, 2010, 2011 and 2012 either by the Bank or by First Federal Bank, acquired by the Bank in July of 2013. As a result of the termination agreement, all assets previously classified as covered became uncovered effective June 23, 2016, and as a result the Bank will now recognize the full amount of future charge-offs, recoveries, gains, losses, and expenses related to these previously covered assets, as the FDIC will no longer share in these amounts.

$ 51,379 $ 298,537 $ 67,612 $ 28,948 $ — $ 696,314 *— The carrying value of acquired credit impaired loans includes a non accretable difference which is primarily associated with the assessment of credit quality of acquired loans. As part of the ongoing monitoring of the credit quality of the Company’s loan portfolio, management tracks certain credit quality indicators, including trends related to (i) the level of classified loans, (ii) net charge-offs, (iii) non-performing loans (see details below), and (iv) the general economic conditions of the markets that we serve. The Company utilizes a risk grading matrix to assign a risk grade to each of its loans. A description of the general characteristics of the risk grades is as follows: · Pass—These loans range from minimal credit risk to average, however, still acceptable credit risk. · Special mention—A special mention loan has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or the institution’s credit position at some future date. · Substandard—A substandard loan is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified must have a well-defined weakness, or weaknesses, that may jeopardize the liquidation of the debt. A substandard loan is characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. · Doubtful—A doubtful loan has all of the weaknesses inherent in one classified as substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of the currently existing facts, conditions and values, highly questionable and improbable.

The Bank recorded a pre-tax charge of $4.4 million, which resulted from a $2.3 million payment to the FDIC as consideration for the early termination, plus the amortization of the remaining FDIC indemnification asset of $2.1 million, net of the clawback, as of March 31, 2016. The entire pre-tax charge was recorded in noninterest income through “Amortization of the FDIC indemnification asset” on the consolidated statements of income. During 2016, the Bank paid a net $853,000 to the FDIC, prior to the termination of the agreements. The indemnification asset was amortized through March 31, 2016. All assets previously classified as covered became uncovered effective June 23, 2016, and as a result the Bank recognizes the full amount of future charge-offs, recoveries, gains, losses, and expenses related to these previously covered assets, as the FDIC will no longer share in these amounts. As of the termination date, covered loans totaled $87.4 million and covered other real estate owned (“OREO”) totaled $3.0 million.

Retirement Plans
Retirement Plans	Note 10 — Retirement Plans The Company and the Bank provide certain retirement benefits to their employees in the form of a non-contributory defined benefit pension plan and an employees’ savings plan. The non-contributory defined benefit pension plan covers all employees hired on or before December 31, 2005, who have attained age 21, and who have completed a year of eligible service. Employees hired on or after January 1, 2006 are not eligible to participate in the non-contributory defined benefit pension plan, but are eligible to participate in the employees’ savings plan. On this date, a new benefit formula applies only to participants who have not attained age 45 or who do not have five years of service. Effective July 1, 2009, the Company suspended the accrual of benefits for pension plan participants under the non-contributory defined benefit plan. The pension plan remained suspended as of March 31, 2017. The components of net periodic pension expense recognized are as follows: Three Months Ended (Dollars in thousands) 2017 2016 Interest cost $ $ Expected return on plan assets Recognized net actuarial loss Net periodic pension benefit $ $ The Company did not contribute to the pension plan for the three months ended March 31, 2017, and does not expect to make any additional contributions during the remainder of 2017. The Company reserves the right to contribute between the minimum required and maximum deductible amounts as determined under applicable federal laws. Under the provisions of Internal Revenue Code Section 401(k), electing employees are eligible to participate in the employees’ savings plan after attaining age 21. Plan participants elect to contribute portions of their annual base compensation as a before tax contribution. Employer contributions may be made from current or accumulated net profits. Participants may elect to contribute 1% to 50% of annual base compensation as a before tax contribution. Employees participating in the plan receive a 100% matching of their 401(k) plan contribution, up to 5% of their salary. Beginning on January 1, 2015, employees are eligible for an additional 1% discretionary matching contribution contingent upon achievement of the Company’s annual financial goals and paid in the first quarter of the following year. The Company is offering the additional 1% discretionary matching contribution again in 2017 upon achievement of the Company’s 2017 financial goals. The Company expensed $1.6 million and $1.3 million for the 401(k) plan during the three months ended March 31, 2017 and 2016. Employees can enter the savings plan on or after the first day of each month. The employee may enter into a salary deferral agreement at any time to select an alternative deferral amount or to elect not to defer in the plan. If the employee does not elect an investment allocation, the plan administrator will select a retirement-based portfolio according to the employee’s number of years until normal retirement age. The plan’s investment valuations are generally provided on a daily basis.

Earnings Per Share
Earnings Per Share	Note 11 — Earnings Per Share Basic earnings per share are calculated by dividing net income by the weighted-average shares of common stock outstanding during each period, excluding non-vested shares. The Company’s diluted earnings per share are based on the weighted-average shares of common stock outstanding during each period plus the maximum dilutive effect of common stock issuable upon exercise of stock options or vesting of restricted shares. The weighted-average number of shares and equivalents are determined after giving retroactive effect to stock dividends and stock splits. The following table sets forth the computation of basic and diluted earnings per share: Three Months Ended March 31, (Dollars and shares in thousands, except for per share amounts) 2017 2016 Basic earnings per common share: Net income $ 18,264 $ 24,494 Weighted-average basic common shares 28,892 23,969 Basic earnings per common share $ $ Diluted earnings per share: Net income $ 18,264 $ 24,494 Weighted-average basic common shares 28,892 23,969 Effect of dilutive securities 267 222 Weighted-average dilutive shares 29,159 24,191 Diluted earnings per common share $ 0.63 $ 1.01 The calculation of diluted earnings per common share excludes outstanding stock options for which the results would have been anti-dilutive under the treasury stock method as follows: Three Months Ended March 31, (Dollars in thousands) 2017 2016 Number of shares Range of exercise prices $ to $ $ to $

Share-Based Compensation
Share-Based Compensation	Note 12 — Share-Based Compensation The Company’s 2004 and 2012 share-based compensation plans are long-term retention plans intended to attract, retain, and provide incentives for key employees and non-employee directors in the form of incentive and non-qualified stock options, restricted stock, and restricted stock units (“RSUs”). Stock Options With the exception of non-qualified stock options granted to directors under the 2004 and 2012 plans, which in some cases may be exercised at any time prior to expiration and in some other cases may be exercised at intervals less than a year following the grant date, incentive stock options granted under the plans may not be exercised in whole or in part within a year following the date of the grant, as these incentive stock options become exercisable in 25% increments pro ratably over the four-year period following the grant date. The options are granted at an exercise price at least equal to the fair value of the common stock at the date of grant and expire ten years from the date of grant. No options were granted under the 2004 plan after January 26, 2012, and the 2004 plan is closed other than for any options still unexercised and outstanding. The 2012 plan is the only plan from which new share-based compensation grants may be issued. It is the Company’s policy to grant options out of the 1,684,000 shares registered under the 2012 plan, of which no more than 817,476 shares can be granted as restricted stock or RSUs. Activity in the Company’s stock option plans is summarized in the following table. All information has been retroactively adjusted for stock dividends and stock splits. Weighted Weighted Average Aggregate Average Remaining Intrinsic Shares Price (Yrs.)

The following weighted-average assumptions were used in valuing options issued: Three months ended March 31, Dividend yield % % Expected life years years Expected volatility % % Risk-free interest rate % % As of March 31, 2017, there was $1.9 million of total unrecognized compensation cost related to nonvested stock option grants under the plans. The cost is expected to be recognized over a weighted-average period of 1.88 years as of March 31, 2017. The total fair value of shares vested during the three months ended March 31, 2017 was $578,000. Restricted Stock The Company from time-to-time also grants shares of restricted stock to key employees and non-employee directors. These awards help align the interests of these employees and directors with the interests of the shareholders of the Company by providing economic value directly related to increases in the value of the Company’s stock. The value of the stock awarded is established as the fair market value of the stock at the time of the grant. The Company recognizes expenses, equal to the total value of such awards, ratably over the vesting period of the stock grants. Restricted stock grants to employees typically “cliff vest” after four years. Grants to non-employee directors typically vest within a 12-month period. All restricted stock agreements are conditioned upon continued employment. Termination of employment prior to a vesting date, as described below, would terminate any interest in non-vested shares. Prior to vesting of the shares, as long as employed by the Company, the key employees and non-employee directors will have the right to vote such shares and to receive dividends paid with respect to such shares. All restricted shares will fully vest in the event of change in control of the Company or upon the death of the recipient. Nonvested restricted stock for the three months ended March 31, 2017 is summarized in the following table. All information has been retroactively adjusted for stock dividends and stock splits. Weighted- Average Grant-Date Restricted Stock Shares Fair Value Nonvested at January 1, 2017 183,014 $ 51.88 Granted 11,273 91.22 Vested (44,011) 43.49 Nonvested at March 31, 2017 150,276 57.29 As of March 31, 2017, there was $5.3 million of total unrecognized compensation cost related to nonvested restricted stock granted under the plans. This cost is expected to be recognized over a weighted-average period of 2.64 years as of March 31, 2017. The total fair value of shares vested during the three months ended March 31, 2017 was $2.0 million. Restricted Stock Units The Company from time-to-time also grants performance and discretionary RSUs to key employees. These awards help align the interests of these employees with the interests of the shareholders of the Company by providing economic value directly related to the performance of the Company. Some performance RSU grants contain a three-year performance period while others contain a one-year performance period and a time vested requirement (generally four years from grant date). The Company communicates threshold, target, and maximum performance RSU awards and performance targets to the applicable key employees at the beginning of a performance period. Discretionary RSUs are based upon prior performance and typically cliff-vest from the grant date over four years. Dividends are not paid in respect to the awards during the performance or the vesting period. The value of the RSUs awarded is established as the fair market value of the stock at the time of the grant. The Company recognizes expenses on a straight-line basis typically over the performance and vesting periods based upon the probable performance target that will be met. For the three months ended March 31, 2017, the Company accrued for 80% of the RSUs granted, based on Management’s expectations of performance. Nonvested RSUs for the three months ended March 31, 2017 is summarized in the following table. Weighted- Average Grant-Date Restricted Stock Units Shares Fair Value Nonvested at January 1, 2017 107,876 $ 66.37 Granted 61,193 89.40 LTIP Adjustment (3,951) 63.93 Nonvested at March 31, 2017 165,118 74.96 As of March 31, 2017, there was $6.2 million of total unrecognized compensation cost related to nonvested RSUs granted under the plan. This cost is expected to be recognized over a weighted-average period of 2.2 years as of March 31, 2017. The total fair value of RSUs vested during the three months ended March 31, 2017 was $2.3 million. During the three months ended March 31, 2017, 57,455 vested restricted stock units were issued to the participants in the 2014 Long-Term Incentive Plan.

Commitments and Contingent Liabilities
Commitments and Contingent Liabilities	Note 13 — Commitments and Contingent Liabilities In the normal course of business, the Company makes various commitments and incurs certain contingent liabilities, which are not reflected in the accompanying financial statements. The commitments and contingent liabilities include guarantees, commitments to extend credit, and standby letters of credit. At March 31, 2017, commitments to extend credit and standby letters of credit totaled $2.0 billion. The Company does not anticipate any material losses as a result of these transactions. The Company has been named as defendant in various legal actions, arising from its normal business activities, in which damages in various amounts are claimed. The Company is also exposed to litigation risk related to the prior business activities of banks acquired through whole bank acquisitions as well as banks from which assets were acquired and liabilities assumed in FDIC-assisted transactions. Although the amount of any ultimate liability with respect to such matters cannot be determined, in the opinion of management, any such liability will not have a material effect on the Company’s consolidated financial statements.

Fair Value
Fair Value	Note 14 — Fair Value FASB ASC 820, Fair Value Measurements and Disclosures , defines fair value, establishes a framework for measuring fair value under accounting principles generally accepted in the United States, and enhances disclosures about fair value measurements. FASB ASC 820 clarifies that fair value should be based on the assumptions market participants would use when pricing an asset or liability and establishes a fair value hierarchy that prioritizes the information used to develop those assumptions. The Company utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Available for sale securities, derivative contracts, and mortgage servicing rights are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may be required to record at fair value other assets on a nonrecurring basis, such as impaired loans, OREO, and certain other assets. These nonrecurring fair value adjustments typically involve application of lower of cost or market accounting or write-downs of individual assets. FASB ASC 820 establishes a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value as follows: Level 1 Observable inputs such as quoted prices in active markets; Level 2 Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and Level 3 Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. The following is a description of valuation methodologies used for assets recorded at fair value. Investment Securities Securities available for sale are valued on a recurring basis at quoted market prices where available. If quoted market prices are not available, fair values are based on quoted market prices of comparable securities. Level 1 securities include those traded on an active exchange, such as the New York Stock Exchange and The NASDAQ Stock Market, or U.S. Treasury securities that are traded by dealers or brokers in active over-the-counter markets and money market funds. Level 2 securities include mortgage-backed securities and debentures issued by government sponsored entities, municipal bonds and corporate debt securities. Securities held to maturity are valued at quoted market prices or dealer quotes similar to securities available for sale. The carrying value of FHLB stock approximates fair value based on the redemption provisions. Mortgage Loans Held for Sale Mortgage loans held for sale are carried at fair value. The fair values of mortgage loans held for sale are based on commitments on hand from investors within the secondary market for loans with similar characteristics. As such, the fair value adjustments for mortgage loans held for sale are recurring Level 2. Loans The Company does not record loans at fair value on a recurring basis. However, from time to time, a loan may be considered impaired and an allowance for loan losses may be established. Loans for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement are considered impaired. Once a loan is identified as individually impaired, management measures impairment using estimated fair value methodologies. The fair value of impaired loans is estimated using one of several methods, including collateral value, market value of similar debt, enterprise value, liquidation value and discounted cash flows. Those impaired loans not requiring an allowance represent loans for which the fair value of the expected repayments or collateral exceed the recorded investments in such loans. At March 31, 2017, substantially all of the impaired loans were evaluated based on the fair value of the collateral because such loans were considered collateral dependent. Impaired loans, where an allowance is established based on the fair value of collateral; require classification in the fair value hierarchy. When the fair value of the collateral is based on an observable market price or a current appraised value, the Company considers the impaired loan as nonrecurring Level 2. When an appraised value is not available or management determines the fair value of the collateral is further impaired below the appraised value and there is no observable market price, the Company considers the impaired loan as nonrecurring Level 3. Other Real Estate Owned (“OREO”) Typically OREO, consisting of properties obtained through foreclosure or in satisfaction of loans, is reported at fair value, determined on the basis of current appraisals, comparable sales, and other estimates of value obtained principally from independent sources, adjusted for estimated selling costs (Level 2). However, OREO is considered Level 3 in the fair value hierarchy because management has qualitatively applied a discount due to the size, supply of inventory, and the incremental discounts applied to the appraisals. Management also considers other factors, including changes in absorption rates, length of time the property has been on the market and anticipated sales values, which have resulted in adjustments to the collateral value estimates indicated in certain appraisals. At the time of foreclosure, any excess of the loan balance over the fair value of the real estate held as collateral is treated as a charge against the allowance for loan losses. Gains or losses on sale and generally any subsequent adjustments to the value are recorded as a component of OREO expense. Derivative Financial Instruments Fair value is estimated using pricing models of derivatives with similar characteristics; accordingly, the derivatives are classified within Level 2 of the fair value hierarchy (see Note 16—Derivative Financial Instruments for additional information). Mortgage servicing rights (“MSRs”) The estimated fair value of MSRs is obtained through an independent derivatives dealer analysis of future cash flows. The evaluation utilizes assumptions market participants would use in determining fair value including market discount rates, prepayment speeds, servicing income, servicing costs, default rates and other market driven data, as well as the market’s perception of future interest rate movements. MSRs are classified as Level 3.

However, since Level 3 financial instruments typically include, in addition to the unobservable or Level 3 components, observable components (that is, components that are actively quoted and can be validated to external sources), the gains and losses below include changes in fair value due in part to observable factors that are part of the valuation methodology. There were no changes in hierarchy classifications of Level 3 assets or liabilities for the three months ended March 31, 2017.

In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those models are significantly affected by the assumptions used, including the discount rates and estimates of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, could not be realized in immediate settlement of the instrument. The use of different methodologies may have a material effect on the estimated fair value amounts. The fair value estimates presented herein are based on pertinent information available to management as of March 31, 2017, December 31, 2016 and March 31, 2016. Such amounts have not been revalued for purposes of these consolidated financial statements since those dates and, therefore, current estimates of fair value may differ significantly from the amounts presented herein. The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value: Cash and Cash Equivalents — The carrying amount is a reasonable estimate of fair value. Investment Securities — Securities held to maturity are valued at quoted market prices or dealer quotes. The carrying value of FHLB stock approximates fair value based on the redemption provisions. The carrying value of the Company’s investment in unconsolidated subsidiaries approximates fair value. See Note 5—Investment Securities for additional information, as well as page 39 regarding fair value. Loans held for sale — The fair values disclosed for loans held for sale are based on commitments from investors for loans with similar characteristics. Loans — For variable-rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values. Fair values for certain mortgage loans (e.g., one-to-four family residential) and other consumer loans are estimated using discounted cash flow analyses based on the Company’s current rates offered for new loans of the same type, structure and credit quality. Fair values for other loans (e.g., commercial real estate and investment property mortgage loans, commercial and industrial loans) are estimated using discounted cash flow analyses, using interest rates currently being offered by the Company for loans with similar terms to borrowers of similar credit quality. Fair values for non-performing loans are estimated using discounted cash flow analyses or underlying collateral values, where applicable. FDIC Receivable for Loss Share Agreements — The fair value is estimated based on discounted future cash flows using current discount rates which has been applied to the expected receipts from the FDIC (which are reduced from revised credit projections) and are less than the clawback estimate. Deposit Liabilities — The fair values disclosed for demand deposits (e.g., interest and non-interest bearing checking, passbook savings, and certain types of money market accounts) are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amounts). The carrying amounts of variable-rate, fixed-term money market accounts, and certificates of deposit approximate their fair values at the reporting date. Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits. Federal Funds Purchased and Securities Sold Under Agreements to Repurchase — The carrying amount of federal funds purchased, borrowings under repurchase agreements, and other short-term borrowings maturing within ninety days approximate their fair values. Other Borrowings — The fair value of other borrowings is estimated using discounted cash flow analysis on the Company’s current incremental borrowing rates for similar types of instruments. Accrued Interest — The carrying amounts of accrued interest approximate fair value. Derivative Financial Instruments — The fair value of derivative financial instruments (including interest rate swaps) is estimated using pricing models of derivatives with similar characteristics. Commitments to Extend Credit, Standby Letters of Credit and Financial Guarantees — The fair values of commitments to extend credit are estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counterparties. For fixed-rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates. The fair values of guarantees and letters of credit are based on fees currently charged for similar agreements or on the estimated costs to terminate them or otherwise settle the obligations with the counterparties at the reporting date. The estimated fair value, and related carrying amount, of the Company’s financial instruments are as follows: Carrying Fair (Dollars in thousands) Amount Value Level 1 Level 2 Level 3 March 31, 2017 Financial assets: Cash and cash equivalents $ 663,126 $ 663,126 $ 663,126 $ — $ — Investment securities 1,400,609 1,400,731 16,267 1,384,464 — Loans held for sale 46,988 46,988 — 46,988 — Loans, net of allowance for loan losses 7,868,840 7,936,291 — — 7,936,291 FDIC receivable for loss share agreements — — — — — Accrued interest receivable 22,823 22,823 — 5,558 17,265 Mortgage servicing rights 30,063 30,063 — — 30,063 Interest rate swap - non-designated hedge 133 133 — 133 — Other derivative financial instruments (mortgage banking related) 2,280 2,280 — 2,280 — Financial liabilities: Deposits 9,033,438 8,462,144 — 8,462,144 — Federal funds purchased and securities sold under agreements to repurchase 352,431 352,431 — 352,431 — Other borrowings 107,988 109,470 — 109,470 — Accrued interest payable 1,452 1,452 — 1,452 — Interest rate swap - non-designated hedge 121 121 — 121 — Interest rate swap - cash flow hedge 426 426 — 426 — Other derivative financial instruments (mortgage banking related) 387 387 — 387 — Off balance sheet financial instruments: Commitments to extend credit — 16,756 — 16,756 — December 31, 2016 Financial assets: Cash and cash equivalents $ 374,448 $ 374,448 $ 374,448 $ — $ — Investment securities 1,014,981 1,015,137 12,041 1,003,096 — Loans held for sale 50,572 50,572 — 50,572 — Loans, net of allowance for loan losses 6,643,326 6,649,575 — — 6,649,575 FDIC receivable for loss share agreements — — — — — Accrued interest receivable 18,618 18,618 — 3,642 14,976 Mortgage servicing rights 29,037 29,037 — — 29,037 Interest rate swap - non-designated hedge 203 203 — 203 — Other derivative financial instruments (mortgage banking related) 2,403 2,403 — 2,403 — Financial liabilities: Deposits 7,334,423 6,935,867 — 6,935,867 — Federal funds purchased and securities sold under agreements to repurchase 313,773 313,773 — 313,773 — Other borrowings 55,358 54,379 — 54,379 — Accrued interest payable 1,359 1,359 — 1,359 — Interest rate swap - non-designated hedge 181 181 — 181 — Interest rate swap - cash flow hedge — — Other derivative financial instruments (mortgage banking related) 51 51 — 51 — Off balance sheet financial instruments: Commitments to extend credit — 1,587 — 1,587 — March 31, 2016 Financial assets: Cash and cash equivalents $ 697,277 $ 697,277 $ 697,277 $ — $ — Investment securities 995,506 995,866 12,075 983,791 — Loans held for sale 34,933 34,933 — 34,933 — Loans, net of allowance for loan losses 6,129,228 6,257,082 — — 6,257,082 FDIC receivable for loss share agreements 2,091 (4,224) — — (4,224) Accrued interest receivable 18,023 18,023 — 3,964 14,059 Mortgage servicing rights 23,697 23,697 — — 23,697 Other derivative financial instruments (mortgage banking related) 3,439 3,439 — 3,439 — Financial liabilities: Deposits 7,161,948 6,950,947 — 6,950,947 — Federal funds purchased and securities sold under agreements to repurchase 312,034 312,034 — 312,034 — Other borrowings 55,210 49,230 — 49,230 — Accrued interest payable 1,926 1,926 — 1,926 — Interest rate swap - cash flow hedge — — Other derivative financial instruments (mortgage banking related) 611 611 — 611 — Off balance sheet financial instruments: Commitments to extend credit — 33,260 — 33,260 —

Derivative Financial Instruments
Derivative Financial Instruments	Note 16 — Derivative Financial Instruments Cash Flow Hedge of Interest Rate Risk The Company utilizes an interest rate swap agreement to essentially convert a portion of its variable-rate debt to a fixed rate (cash flow hedge). For derivatives designated as hedging exposure to variable cash flows of a forecasted transaction (cash flow hedge), the effective portion of the derivative’s gain or loss is initially reported as a component of other comprehensive income and subsequently reclassified into earnings when the forecasted transaction affects earnings or when the hedge is terminated. The ineffective portion of the gain or loss is reported in earnings immediately. For derivatives that are not designated as hedging instruments, changes in the fair value of the derivatives are recognized in earnings immediately. When applying hedge accounting for derivatives, the Company establishes a method for assessing the effectiveness of the hedging derivative and a measurement approach for determining the ineffective aspect of the hedge upon the inception of the hedge. During 2009, the Company entered into a forward starting interest rate swap agreement with a notional amount of $8.0 million to manage interest rate risk due to periodic rate resets on its junior subordinated debt issued by SCBT Capital Trust II, an unconsolidated subsidiary of the Company established for the purpose of issuing trust preferred securities. The Company hedges the variable rate cash flows of subordinated debt against future interest rate increases by using an interest rate swap that effectively fixed the rate on the debt beginning on June 15, 2010, at which time the debt contractually converted from a fixed interest rate to a variable interest rate. This hedge expires on June 15, 2019. The notional amount on which the interest payments are based will not be exchanged. This derivatives contract calls for the Company to pay a fixed rate of 4.06% on $8.0 million notional amount and receive a variable rate of three-month LIBOR on the $8.0 million notional amount. The Company recognized an after-tax unrealized gain on its cash flow hedge in other comprehensive income of $44,000 for the three months ended March 31, 2017, compared to an unrealized loss of $49,000 for the three months ended March 31, 2016. The Company recognized a $426,000 cash flow hedge liability in other liabilities on the balance sheet at March 31, 2017, compared to a $797,000 liability at March 31, 2016. There was no ineffectiveness in the cash flow hedge during the three months ended March 31, 2017 and 2016. On January 3, 2017, the Company, through its merger with Southeastern Banking Financial Corporation (“SBFC”), acquired two forward starting interest rate swaps with a total notational amount of $10.0 million which was used to manage interest rate risk by SBFC on its $20.6 million in junior subordinated debt issued by capital trusts. Like the Company, SBFC was using the swaps to hedge the variable rate cash flows of subordinated debt against future interest rate increases by using an interest rate swap that effectively fixed the rate on the debt. The subordinated debt was paying interest at three month LIBOR plus 1.40% (2.36% at the time of the merger) while the interest rate swaps were providing a fixed rate of approximately 5.35% on $10.0 million of the junior subordinated debt. During the first quarter of 2017, the Company decided to terminate the interest rate swaps acquired through the merger with SBFC with an immaterial effect to net income. Credit risk related to the derivative arises when amounts receivable from the counterparty (derivatives dealer) exceed those payable. The Company controls the risk of loss by only transacting with derivatives dealers that are national market makers whose credit ratings are strong. Each party to the interest rate swap is required to provide collateral in the form of cash or securities to the counterparty when the counterparty’s exposure to a mark-to-market replacement value exceeds certain negotiated limits. These limits are typically based on current credit ratings and vary with ratings changes. As of March 31, 2017 and 2016, the Company provided $550,000 and $850,000 of collateral, which is included in cash and cash equivalents on the balance sheet as interest-bearing deposits with banks. Also, the Company has a netting agreement with the counterparty. Non-designated Hedges of Interest Rate Risk Customer Swap On December 28, 2016, the Company entered into two interest rate swap contracts that were classified as non-designated hedges and are not speculative in nature. One of the derivatives is an interest rate swap that was executed with a commercial borrower to facilitate a respective risk management strategy and allow the customer to pay a fixed rate of interest to the Company. This interest rate swap was simultaneously hedged by executing an offsetting interest rate swap that was entered into with a derivatives dealer to minimize the net risk exposure to the Company resulting from the transactions and allow the Company to receive a variable rate of interest. As the interest rate swaps associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. As of March 31, 2017, the interest rate swaps had an aggregate notional amount of approximately $27.5 million and the fair value of these two interest rate swap derivatives are recorded in other assets and in other liabilities for a net asset carrying value of $12,000, which was recorded through earnings. Mortgage Banking The Company also has derivatives contracts that are classified as non-designated hedges. These derivatives contracts are a part of the Company’s risk management strategy for its mortgage banking activities. These instruments may include financial forwards, futures contracts, and options written and purchased, which are used to hedge mortgage servicing rights; while forward sales commitments are typically used to hedge the mortgage pipeline. Such instruments derive their cash flows, and therefore their values, by reference to an underlying instrument, index or referenced interest rate. The Company does not elect hedge accounting treatment for any of these derivative instruments and as a result, changes in fair value of the instruments (both gains and losses) are recorded in the Company’s consolidated statements of income in mortgage banking income. Mortgage Servicing Rights Derivatives contracts related to mortgage servicing rights are used to help offset changes in fair value and are written in amounts referred to as notional amounts. Notional amounts provide a basis for calculating payments between counterparties but do not represent amounts to be exchanged between the parties, and are not a measure of financial risk. On March 31, 2017, the Company had derivative financial instruments outstanding with notional amounts totaling $98.0 million related to mortgage servicing rights, compared to $121.0 million on March 31, 2016. The estimated net fair value of the open contracts related to the mortgage servicing rights was recorded as a gain of $214,000 at March 31, 2017, compared to a loss of $150,000 at March 31, 2016.

Capital Ratios
Capital Ratios	Note 17 — Capital Ratios The Company is subject to regulations with respect to certain risk-based capital ratios. These risk-based capital ratios measure the relationship of capital to a combination of balance sheet and off-balance sheet risks. The values of both balance sheet and off-balance sheet items are adjusted based on the rules to reflect categorical credit risk. In addition to the risk-based capital ratios, the regulatory agencies have also established a leverage ratio for assessing capital adequacy. The leverage ratio is equal to Tier 1 capital divided by total consolidated on-balance sheet assets (minus amounts deducted from Tier 1 capital). The leverage ratio does not involve assigning risk weights to assets. In July 2013, the Federal Reserve announced its approval of a final rule to implement the regulatory capital reforms developed by the Basel Committee on Banking Supervision (“Basel III”), among other changes required by the Dodd-Frank Wall Street Reform and Consumer Protection Act. The new rules became effective January 1, 2015, subject to a phase-in period for certain aspects of the new rules. As applied to the Company and the Bank, the new rules include a new minimum ratio of common equity Tier 1 capital ("CET1") to risk-weighted assets of 4.5%. The new rules also raised the minimum required ratio of Tier 1 capital to risk-weighted assets from 4% to 6%. The minimum required leverage ratio under the new rules is 4%. The minimum required total capital to risk-weighted assets ratio remains at 8% under the new rules. In order to avoid restrictions on capital distributions and discretionary bonus payments to executives, under the new rules a covered banking organization is also required to maintain a “capital conservation buffer” in addition to its minimum risk-based capital requirements. This buffer is required to consist solely of common equity Tier 1, and the buffer applies to all three risk-based measurements (CET1, Tier 1 capital and total capital). The capital conservation buffer will be phased in incrementally over time, beginning January 1, 2016 and becoming fully effective on January 1, 2019, and will ultimately consist of an additional amount of Tier 1 common equity equal to 2.5% of risk-weighted assets. The Bank is also subject to the regulatory framework for prompt corrective action, which identifies five capital categories for insured depository institutions (well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized) and is based on specified thresholds for each of the three risk-based regulatory capital ratios (CET1, Tier 1 capital and total capital) and for the leverage ratio. The following table presents actual and required capital ratios as of March 31, 2017, December 31, 2016 and March 31, 2016 for the Company and the Bank under the Basel III capital rules. The minimum required capital amounts presented include the minimum required capital levels as of March 31, 2017 based on the phase-in provisions of the Basel III Capital Rules and the minimum required capital levels as of January 1, 2019 when the Basel III Capital Rules have been fully phased-in.

Servicing loans for others generally consists of collecting mortgage payments, maintaining escrow accounts and disbursing payments to investors. The amount of contractually specified servicing fees earned by the Company during the three months ended March 31, 2017 and March 31, 2016 was $1.8 million and $1.5 million, respectively. Servicing fees are recorded in mortgage banking income in the Company’s consolidated statements of income. At March 31, 2017, December 31, 2016, and March 31, 2016, mortgage servicing rights (“MSRs”) were $30.1 million, $29.0 million, and $23.7 million on the Company’s consolidated balance sheets, respectively. MSRs are recorded at fair value with changes in fair value recorded as a component of mortgage banking income in the consolidated statements of income. The market value adjustments related to MSRs recorded in mortgage banking income for the three months ended March 31, 2017 and March 31, 2016 were a gain of $444,000 and a loss of $2.6 million, respectively. The Company has used various free standing derivative instruments to mitigate the income statement effect of changes in fair value due to changes in market value adjustments and to changes in valuation inputs and assumptions related to MSRs. See Note 14 — Fair Value for the changes in fair value of MSRs. The following table presents the changes in the fair value of the offsetting hedge. Three Months Ended (Dollars in thousands) March 31, 2017 March 31, 2016 Increase (decrease) in fair value of MSRs $ $ (2,606) Decay of MSRs (780) Gains related to derivatives $ $ 3,045 Net effect on statements of income $ $ (341) The fair value of MSRs is highly sensitive to changes in assumptions and fair value is determined by estimating the present value of the asset’s future cash flows utilizing market-based prepayment rates, discount rates and other assumptions validated through comparison to trade information, industry surveys and with the use of independent third party appraisals. Changes in prepayment speed assumptions have the most significant impact on the fair value of MSRs. Generally, as interest rates decline, mortgage loan prepayments accelerate due to increased refinance activity, which results in a decrease in the fair value of the MSR. Measurement of fair value is limited to the conditions existing and the assumptions utilized as of a particular point in time, and those assumptions may not be appropriate if they are applied at a different time. See Note 14 — Fair Value for additional information regarding fair value. The characteristics and sensitivity analysis of the MSR are included in the following table. March 31, December 31, March 31, (Dollars in thousands) 2017 2016 2016 Composition of residential loans serviced for others Fixed-rate mortgage loans 99.6 % 99.6 % 99.4 % Adjustable-rate mortgage loans 0.4 % 0.4 % 0.6 % Total 100.0 % 100.0 % 100.0 % Weighted average life years years 6.10 years Constant Prepayment rate (CPR) 7.8 % 7.7 % 11.8 % Weighted average discount rate 9.8 % 9.8 % 9.8 % Effect on fair value due to change in interest rates 25 basis point increase $ 1,375 $ 1,399 $ 1,884 50 basis point increase 2,431 2,557 3,532 25 basis point decrease (1,746) (1,713) (2,206) 50 basis point decrease (3,774) (3,670) (4,477) The sensitivity calculations in the previous table are hypothetical and should not be considered to be predictive of future performance. Changes in fair value based on adverse changes in assumptions generally cannot be extrapolated because the relationship of the changes in assumptions to fair value may not be linear. Also, the effects of an adverse variation in a particular assumption on the fair value of the MSRs is calculated without changing any other assumptions, while in reality, changes in one factor may result in changing another, which may magnify or contract the effect of the change. Custodial escrow balances maintained in connection with the loan servicing were $18.2 million and $16.4 million at March 31, 2017 and March 31, 2016, respectively. Mandatory cash forwards and whole loan sales were $177.7 million and $135.9 million for the three months ended March 31, 2017 and March 31, 2016, respectively, of which $120.6 million and $93.3 million, or 67.9% and 68.7%, respectively, were sold with the servicing rights retained by the company. Loans held for sale have historically been comprised of residential mortgage loans awaiting sale in the secondary market, which generally settle in 15 to 45 days. Loans held for sale, which consists primarily of residential mortgage loans to be sold in the secondary market, were $47.0 million, $50.6 million, and $34.9 million at March 31, 2017, December 31, 2016, and March 31, 2016, respectively.

Disclosure of Repurchase Agreements [Abstract]
Repurchase Agreements	Note 21 – Repurchase Agreements Securities sold under agreements to repurchase ("repurchase agreements") represent funds received from customers, generally on an overnight or continuous basis, which are collateralized by investment securities owned or, at times, borrowed and re-hypothecated by the Company. Repurchase agreements are subject to terms and conditions of the master repurchase agreements between the Company and the client and are accounted for as secured borrowings. Repurchase agreements are included in federal funds purchased and securities sold under agreements to repurchase on the condensed consolidated balance sheets. At March 31, 2017, December 31, 2016 and March 31, 2016, the Company's repurchase agreement totaled $272.4 million, $238.3 million, and $257.4 million, respectively. All of the Company’s repurchase agreements were overnight or continuous (until-further-notice) agreements at March 31, 2017, December 31, 2016 and March 31, 2016. These borrowings were collateralized with government, government-sponsored enterprise, or state and political subdivision-issued securities with a carrying value of $272.4 million, $238.3 million and $257.4 million at March 31, 2017, December 31, 2016 and March 31, 2016, respectively. Declines in the value of the collateral would require the Company to increase the amounts of securities pledged.
