Notes to Unaudited Interim Consolidated Financial Statements

Note 1 - Significant Accounting Policies

Business Operations

The accompanying unaudited interim consolidated financial statements of Synovus Financial Corp. include the accounts of the Parent Company and its consolidated subsidiaries. Synovus Financial Corp. is a financial services company based in Columbus, Georgia. Through its wholly-owned subsidiary, Synovus Bank, a Georgia state-chartered bank that is a member of the Federal Reserve System, the company provides commercial and retail banking in addition to a full suite of specialized products and services including private banking, treasury management, wealth management, premium finance and international banking.

Synovus Bank is positioned in some of the highest growth markets in the Southeast, with 250 branches and 334 ATMs in Georgia, Alabama, South Carolina, Florida, and Tennessee.

Basis of Presentation

The accompanying unaudited interim consolidated financial statements have been prepared in accordance with the instructions to the SEC Form 10-Q and Article 10 of Regulation S-X; therefore, they do not include all information and footnotes necessary for a fair presentation of financial position, results of operations, comprehensive income, and cash flows in conformity with GAAP. All adjustments consisting of normally recurring accruals that, in the opinion of management, are necessary for a fair presentation of the consolidated financial position and results of operations for the periods covered by this Report have been included. The accompanying unaudited interim consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes appearing in Synovus' 2017 Form 10-K.

In connection with the adoption of ASU 2016-18, Statement of Cash Flows-Restricted Cash, Synovus changed its presentation of cash and cash equivalents, effective January 1, 2018, to include cash and due from banks as well as interest bearing funds with the Federal Reserve Bank, interest earning deposits with banks, and federal funds sold and securities purchased under resale agreements, which are inclusive of any restricted cash and restricted cash equivalents. Prior to 2018, cash and cash equivalents only included cash and due from banks. Prior periods have been revised to maintain comparability. Excluding the aforementioned presentation change, there have been no significant changes to the accounting policies as disclosed in Synovus' 2017 Form 10-K.

In preparing the unaudited interim consolidated financial statements in accordance with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the respective consolidated balance sheets and the reported amounts of revenues and expenses for the periods presented. Actual results could differ significantly from those estimates.

Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses, the fair value of investment securities, and the fair value of private equity investments.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash and due from banks, interest bearing funds with the Federal Reserve Bank, interest earning deposits with banks, federal funds sold and securities purchased under resale agreements, and is inclusive of any restricted cash and restricted cash equivalents. Restricted cash and restricted cash equivalents primarily relate to cash held on deposit with the Federal Reserve to meet reserve requirements as well as cash posted as collateral for derivatives in a liability position. At June 30, 2018 and December 31, 2017, interest bearing funds with the Federal Reserve Bank included $35.7 million and $8.6 million, respectively, on deposit to meet Federal Reserve Bank requirements. Interest earning deposits with banks include $2.7 million and $5.9 million at June 30, 2018 and December 31, 2017, respectively, which are pledged as collateral in connection with certain letters of credit. Federal funds sold include $30.6 million and $43.8 million at June 30, 2018 and December 31, 2017, respectively, which are pledged to collateralize certain derivative financial instruments. Federal funds sold and securities purchased under resale agreements generally mature in one day.

Income Taxes

On December 22, 2017, Federal Tax Reform was enacted into law. The new legislation included a decrease in the corporate federal income tax rate from 35% to 21% effective January 1, 2018. Under ASC 740, the effects of the changes in tax rates and laws are recognized in the period in which the new legislation is enacted. Therefore, Synovus was required to remeasure its deferred tax assets and liabilities and record the adjustment to income tax expense effective December 22, 2017. In December 2017, the SEC issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (SAB 118), which allowed companies to record provisional amounts during a measurement period not to extend beyond one year of the enactment date. Since Federal Tax Reform was enacted late in 2017, management expects that certain deferred tax assets and liabilities will continue to be evaluated in the context of Federal Tax Reform through the date of the filing of our 2017 federal income tax return, and may change as a result of evolving management interpretations, elections, and assumptions, as well as new guidance that may be issued by the Internal Revenue Service.   Accordingly, the federal income tax expense of $47.2 million

6

recorded in 2017 relating to the effects from Federal Tax Reform is considered provisional. Management expects to complete its analysis within the measurement period in accordance with SAB 118.  

Recently Adopted Accounting Standards Updates

ASU 2014-09, Revenue from Contracts with Customers (Topic 606) issued by the FASB in May 2014, and all subsequent ASUs that modified 606. ASU 2014-09 implements a common revenue standard that establishes principles for reporting information about the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts to provide goods or services to customers. The core principle of the revenue model is that a company will recognize revenue when it transfers control of goods or services to customers at an amount that reflects the consideration to which it expects to be entitled in exchange for those goods or services. The scope of the guidance explicitly excludes net interest income as well as many other revenues from financial assets. Management reviewed its revenue streams and contracts with customers and did not identify material changes to the timing or amount of revenue recognition. Synovus adopted these ASUs on the required effective date of January 1, 2018 utilizing the modified retrospective method of adoption.  The adoption resulted in a cumulative effect adjustment of ($685) thousand to the opening balance of retained earnings.  Beginning January 1, 2018, in connection with the adoption of this standard, Synovus began including merchant discounts and other card-related fees in card fees. For periods prior to January 1, 2018, these amounts were previously presented in other non-interest income and have been reclassified for comparability. See "Part I - Item 1. Financial Statements and Supplementary Data - Note 12 - Non-interest Income" for the required disclosures in accordance with this ASU.

ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. In February 2018, the FASB issued final guidance on reclassification of tax effects stranded in other comprehensive income due to Federal Tax Reform. The guidance provides entities the option to reclassify the tax effects that are stranded in accumulated other comprehensive income, or AOCI, as a result of Federal Tax Reform to retained earnings. The guidance is effective for fiscal years beginning after December 15, 2018; early adoption is permitted. Synovus elected to early adopt ASU 2018-02 as of January 1, 2018 and elected to reclassify the income tax effects of Federal Tax Reform from AOCI to retained earnings. For Synovus, tax effects stranded in AOCI due to Federal Tax Reform totaled $7.6 million at December 31, 2017 and primarily related to unrealized losses on the available-for-sale investment securities portfolio. The reclassification adjustment resulted in an increase to retained earnings as of January 1, 2018 of $7.6 million and a corresponding decrease to AOCI for the same amount.

ASU 2016-01, Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. In January 2016, the FASB issued ASU 2016-01 that included targeted amendments to accounting guidance for recognition, measurement, presentation, and disclosure of financial instruments. ASU 2016-01 requires equity investments (except those accounted for under the equity method of accounting or consolidated) to be measured at fair value with changes in fair value recognized in net income. This ASU requires a cumulative-effect adjustment to retained earnings as of the beginning of the reporting period of adoption to reclassify the cumulative change in fair value of equity securities previously recognized in AOCI. ASU 2016-01 became effective for Synovus on January 1, 2018. The adoption of the guidance resulted in a transfer of investments in mutual funds of $3.2 million, at fair value, from investment securities available for sale to other assets and a $117 thousand cumulative-effect adjustment that decreased retained earnings, with offsetting related adjustments to deferred taxes and AOCI. ASU 2016-01 also emphasizes the existing requirement to use an exit price concept to measure fair value for disclosure purposes in determining the fair value of loans. Determination of the fair value under the exit price method requires judgment because substantially all of the loans within the loan portfolio do not have observable market prices. The adoption of this guidance did not have a significant impact on Synovus' fair value disclosures.

Reclassifications

Prior periods' consolidated financial statements are reclassified whenever necessary to conform to the current periods' presentation.

Note 2 - Acquisitions

Cabela's Transaction

On September 25, 2017, Synovus' wholly owned subsidiary, Synovus Bank, completed the acquisition of certain assets and assumption of certain liabilities of World's Foremost Bank, or WFB. Immediately following the closing of this transaction, Synovus Bank sold WFB’s credit card assets and related liabilities to Capital One Bank (USA), National Association, a bank subsidiary of Capital One Financial Corporation.

Synovus retained WFB’s $1.10 billion brokered time deposits portfolio, which had a weighted average remaining maturity of approximately 2.53 years and a weighted average rate of 1.83% as of September 25, 2017. The transaction was accounted for as an assumption of a liability (accounted for under the asset acquisition model). In accordance with ASC 820, Fair Value Measurements and Disclosures, the brokered time deposit portfolio was recorded at $1.10 billion, which was the amount of cash received for the deposits and represented the estimated fair value of the deposits at the transaction date. Additionally, Synovus received a $75.0 million transaction fee from Cabela’s Incorporated and Capital One, which was recognized into earnings on September 25, 2017 upon closing of the transaction, based on having achieved the recognition criteria outlined in SEC SAB Topic 13.A, Revenue Recognition.

Acquisition of Global One

On October 1, 2016, Synovus completed its acquisition of all of the outstanding stock of Global One. Prior to its acquisition, Global One was an Atlanta-based private specialty financial services company that provided financing primarily to commercial entities, with all loans fully collateralized by cash value life insurance policies and/or annuities issued by investment grade life insurance companies. Under the terms of the merger agreement, Synovus acquired Global One for an up-front payment of $30 million, consisting of the issuance of 821 thousand shares of Synovus common stock valued at $26.6 million and $3.4 million in cash, with additional payments to Global One's former shareholders over a three to five year period based on earnings from the Global One business, as further discussed below.

The acquisition of Global One constituted a business combination. Accordingly, the assets acquired and liabilities assumed were recorded at their estimated fair values on October 1, 2016. The determination of fair value required management to make estimates about discount rates, future expected earnings and cash flows, market conditions, future loan growth, and other future events that are highly subjective in nature and subject to change. During the three months ended September 30, 2017, Synovus completed the determination of the final allocation of the purchase price with respect to the assets acquired and liabilities assumed.

Under the terms of the merger agreement, the purchase price includes additional annual payments ("Earnout Payments") to Global One's former shareholders over a three to five year period, with amounts based on a percentage of "Global One Earnings," as defined in the merger agreement. The Earnout Payments consist of shares of Synovus common stock as well as a smaller cash consideration component. The first annual Earnout Payment of stock and cash valued at $6.4 million was made during November 2017. The balance of the earnout liability at June 30, 2018 was $11.3 million based on the estimated fair value of the remaining Earnout Payments.

Note 3 - Share Repurchase Program

On January 23, 2018, Synovus announced a share repurchase program of up to $150 million to be completed during 2018. As of June 30, 2018, Synovus had repurchased under this program a total of $76.8 million, or 1.5 million shares of its common stock, at an average price of $52.72 per share.

Total investment securities available for sale	$	4,038,239	$	6,107	$	(57,277	)	$	3,987,069

At June 30, 2018 and December 31, 2017, investment securities with a carrying value of $1.35 billion and $2.00 billion, respectively, were pledged to secure certain deposits and securities sold under repurchase agreements as required by law and contractual agreements.

Synovus has reviewed investment securities that are in an unrealized loss position as of June 30, 2018 and December 31, 2017 for OTTI and does not consider any securities in an unrealized loss position to be other-than-temporarily impaired. If Synovus intended to sell a security in an unrealized loss position, the entire unrealized loss would be reflected in earnings. Synovus does not intend to sell investment securities in an unrealized loss position prior to the recovery of the unrealized loss, which may not be until maturity, and has the ability and intent to hold those securities for that period of time. Additionally, Synovus is not currently aware of any circumstances which will require it to sell any of the securities that are in an unrealized loss position prior to the respective securities' recovery of all such unrealized losses.

Declines in the fair value of available for sale securities below their cost that are deemed to have OTTI are reflected in earnings as realized losses to the extent the impairment is related to credit losses. The amount of the impairment related to other factors is recognized in other comprehensive income. Currently, unrealized losses on debt securities are attributable to increases in interest rates on comparable securities from the date of purchase. Synovus regularly evaluates its investment securities portfolio to ensure that there are no conditions that would indicate that unrealized losses represent OTTI. These factors include the length of time the security has been in a loss position, the extent that the fair value is below amortized cost, and the credit standing of the issuer.

9

As of June 30, 2018, Synovus had 80 investment securities in a loss position for less than twelve months and 55 investment securities in a loss position for twelve months or longer.

Gross unrealized losses on investment securities and the fair value of the related securities, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, at June 30, 2018 and December 31, 2017 are presented below.

The amortized cost and fair value by contractual maturity of investment securities available for sale at June 30, 2018 are shown below. The expected life of mortgage-backed securities or CMOs may differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties. For purposes of the maturity table, mortgage-backed securities and CMOs, which are not due at a single maturity date, have been classified based on the final contractual maturity date.

The credit quality of the loan portfolio is reviewed and updated no less frequently than quarterly using the standard asset classification system utilized by the federal banking agencies. These classifications are divided into three groups – Not Criticized (Pass), Special Mention, and Classified or Adverse rating (Substandard, Doubtful, and Loss) and are defined as follows:

Pass- loans which are well protected by the current net worth and paying capacity of the obligor (or guarantors, if any) or by the fair value, less cost to acquire and sell in a timely manner, of any underlying collateral.

Special Mention - loans which have potential weaknesses that deserve management's close attention. These loans are not adversely classified and do not expose an institution to sufficient risk to warrant an adverse classification.

Substandard - loans which are inadequately protected by the current net worth and paying capacity of the obligor or by the collateral pledged, if any. Loans with this classification are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected.

Doubtful - loans which have all the weaknesses inherent in loans classified as Substandard with the added characteristic that the weaknesses make collection or liquidation in full highly questionable and improbable on the basis of currently known facts, conditions, and values.

Loss - loans which are considered by management to be uncollectible and of such little value that their continuance on the institution's books as an asset, without establishment of a specific valuation allowance or charge-off, is not warranted.

In the following tables, consumer loans are generally assigned a risk grade similar to the classifications described above; however, upon reaching 90 days and 120 days past due, they are generally downgraded to Substandard and Loss, respectively, in accordance with the FFIEC Uniform Retail Credit Classification and Account Management Policy. Additionally, in accordance with the Interagency Supervisory Guidance on Allowance for Loan and Lease Losses Estimation Practices for Loans and Lines of Credit Secured by Junior Liens on 1-4 Family Residential Properties, the risk grade classifications of home equity lines and consumer mortgages secured by junior liens on 1-4 family residential properties also consider available information on the payment status of any associated senior liens with other financial institutions.

The average recorded investment in impaired loans was $233.8 million and $232.5 million respectively for the six and three months ended June 30, 2017. Excluding accruing TDRs, there was no interest income recognized for the investment in impaired loans for the six and three months ended June 30, 2017. Interest income recognized for accruing TDRs was $3.5 million and $1.8 million respectively for the six and three months ended June 30, 2017. At June 30, 2018 and December 31, 2017, impaired loans of $63.7 million and $49.0 million, respectively, were on non-accrual status.

Concessions provided in a TDR are primarily in the form of providing a below market interest rate given the borrower's credit risk, a period of time generally less than one year with a reduction of required principal and/or interest payments (e.g., interest only for a period of time), or an extension of the maturity of the loan generally for less than one year. Insignificant periods of reduction of principal and/or interest payments, or one-time deferrals of 3 months or less, are generally not considered to be financial concessions.

The following tables represent, by concession type, the post-modification balance for loans modified or renewed during the six and three months ended June 30, 2018 and 2017 that were reported as accruing or non-accruing TDRs.

⁽²⁾ No net charge-offs were recorded during the six and three months ended June 30, 2017 upon restructuring of these loans.

For both the six and three months ended June 30, 2018 there were eight defaults with a recorded investment of $10.5 million on accruing TDRs restructured during the previous twelve months (defaults are defined as the earlier of the TDR being placed on non-accrual status or reaching 90 days past due with respect to principal and/or interest payments) compared to three defaults for both the six and three months ended June 30, 2017 with a recorded investment of $292 thousand.

If, at the time a loan was designated as a TDR, the loan was not already impaired, the measurement of impairment that resulted from the TDR designation closely approximates the reserve derived through specific loan measurement of impairment in accordance with ASC 310-10-35. Generally, the change in the allowance for loan losses resulting from such TDR designation is not significant. At June 30, 2018, the allowance for loan losses allocated to accruing TDRs totaling $125.3 million was $6.5 million compared to accruing TDRs of $151.3 million with an allocated allowance for loan losses of $8.7 million at December 31, 2017. Non-accrual, non-homogeneous loans (commercial-type impaired loans greater than $1 million) that are designated as TDRs are individually measured for the amount of impairment, if any, both before and after the TDR designation.

In accordance with ASC 740-20-45-11(b), a deferred tax asset valuation allowance associated with unrealized gains and losses not recognized in income is charged directly to other comprehensive income (loss). During the years 2010 and 2011, Synovus recorded a deferred tax asset valuation allowance associated with net unrealized losses not recognized in income directly to other comprehensive income (loss) by applying the portfolio approach for allocation of the valuation allowance. Synovus has consistently applied the portfolio approach which treats derivative instruments and available for sale securities as a single portfolio. As of June 30, 2018, the ending balance in net unrealized gains (losses) on cash flow hedges and net unrealized gains (losses) on investment securities available for sale includes unrealized losses of $12.1 million and $13.3 million, respectively, related to the residual tax effects remaining in OCI due to the previously established deferred tax asset valuation allowance. Under the portfolio approach, these unrealized losses are realized at the time the entire portfolio is sold or disposed.

Note 8 - Fair Value Accounting

Synovus carries various assets and liabilities at fair value based on the fair value accounting guidance under ASC 820, Fair Value Measurements, and ASC 825, Financial Instruments. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an “exit price”) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

Fair Value Hierarchy

Synovus determines the fair value of its financial instruments based on the fair value hierarchy established under ASC 820-10, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the financial instrument's fair value measurement in its entirety. There are three levels of inputs that may be used to measure fair value. The three levels of inputs of the valuation hierarchy are defined below:

Level 1	Quoted prices (unadjusted) in active markets for identical assets and liabilities for the instrument or security to be valued. Level 1 assets include U.S. Treasury securities and mutual funds.
Level 2	Observable inputs other than Level 1 quoted prices, such as quoted prices for similar assets and liabilities in active markets, quoted prices in markets that are not active or model-based valuation techniques for which all significant assumptions are derived principally from or corroborated by observable market data. Level 2 assets and liabilities include debt securities with quoted prices that are traded less frequently than exchange-traded instruments and derivative contracts whose value is determined by using a pricing model with inputs that are observable in the market or can be derived principally from or corroborated by observable market data. U.S. Government sponsored agency securities, mortgage-backed securities issued by GSEs and agencies, obligations of states and municipalities, collateralized mortgage obligations issued by GSEs, and mortgage loans held-for-sale are generally included in this category.
Level 3	Unobservable inputs that are supported by little, if any, market activity for the asset or liability. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow models and similar techniques, and may also include the use of market prices of assets or liabilities that are not directly comparable to the subject asset or liability. These methods of valuation may result in a significant portion of the fair value being derived from unobservable assumptions that reflect Synovus' own estimates for assumptions that market participants would use in pricing the asset or liability. This category primarily includes collateral-dependent impaired loans, other loans held for sale, other real estate, certain corporate securities, private equity investments, GGL/SBA loan servicing assets, and the earnout liability.

See "Part II - Item 8. Financial Statements and Supplementary Data - Note 15 - Fair Value Accounting" to the consolidated financial statements of Synovus' 2017 Form 10-K for a description of valuation methodologies for assets and liabilities measured at fair value on a recurring and non-recurring basis.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The following table presents all financial instruments measured at fair value on a recurring basis as of June 30, 2018 and December 31, 2017, according to the valuation hierarchy included in ASC 820-10. For debt securities, class was determined based on the nature and risks of the investments. Synovus did not have any transfers between levels during the six and three months ended June 30, 2018 and year ended December 31, 2017.

Fair Value Option

The following table summarizes the difference between the fair value and the unpaid principal balance of mortgage loans held for sale measured at fair value and the changes in fair value of these loans. Mortgage loans held for sale are initially measured at fair value with subsequent changes in fair value recognized in earnings. Changes in fair value are recorded as a component of mortgage banking income in the consolidated statements of income. An immaterial portion of these changes in fair value was attributable to changes in instrument-specific credit risk.

Changes in Level 3 Fair Value Measurements and Quantitative Information about Level 3 Fair Value Measurements

As noted above, Synovus uses significant unobservable inputs in determining the fair value of assets and liabilities classified as Level 3 in the fair value hierarchy. The table below includes a roll-forward of the amounts on the consolidated balance sheet for the six and three months ended June 30, 2018 and 2017 (including the change in fair value) for financial instruments of a material nature that are classified by Synovus within Level 3 of the fair value hierarchy and are measured at fair value on a recurring basis. Transfers between fair value levels are recognized at the end of the reporting period in which the associated changes in inputs occur. During the six and three months ended June 30, 2018 and 2017, Synovus did not have any transfers between levels in the fair value hierarchy. For the six and three months ended June 30, 2018, total net losses included in earnings attributable to the change in unrealized losses relating to assets/liabilities still held at June 30, 2018 was $6.2 million and $2.7 million, respectively. For the six and three months ended June 30, 2017, total net losses included in earnings attributable to the change in unrealized losses relating to assets/liabilities still held at June 30, 2017 was $2.4 million and $2.1 million, respectively.

Assets Measured at Fair Value on a Non-recurring Basis

Certain assets are recorded at fair value on a non-recurring basis. These assets are not measured at fair value on an ongoing basis. Non-recurring fair value adjustments typically are a result of the application of lower of cost or fair value accounting or a write-down occurring during the period. For example, if the fair value of an asset in these categories falls below its cost basis, it is considered to be at fair value at the end of the period of the adjustment. The following table presents assets measured at fair value on a non-recurring basis as of the dates indicated for which there was a fair value adjustment during the six months ended June 30, 2018 and year ended December 31, 2017.

⁽¹⁾ The range represents management's estimate of the high and low of the value that would be assigned to a particular input. For assets measured at fair value on a non-recurring basis, the weighted average is the measure of central tendencies; it is not the value that management is using for the asset or liability.

⁽²⁾ Synovus also makes adjustments to the values of the assets listed above for reasons including age of the appraisal, information known by management about the property, such as occupancy rates, changes to the physical condition of the property, and other factors.

Fair Value of Financial Instruments

The following table presents the carrying and fair values of financial instruments at June 30, 2018 and December 31, 2017. The fair values represent management’s estimates based on various methodologies and assumptions. For financial instruments that are not recorded at fair value on the balance sheet, such as loans held for investment, interest bearing deposits (including brokered deposits), and long-term debt, the fair value amounts should not be taken as an estimate of the amount that would be realized if all such financial instruments were to be settled immediately.

Note 9 - Derivative Instruments

As part of its overall interest rate risk management activities, Synovus utilizes derivative instruments to manage its exposure to various types of interest rate risk. These derivative instruments generally consist of interest rate swaps, interest rate lock commitments made to prospective mortgage loan customers, and commitments to sell fixed-rate mortgage loans. Interest rate lock commitments represent derivative instruments since it is intended that such loans will be sold.

Synovus may also utilize interest rate swaps to manage interest rate risks primarily arising from its core banking activities. These interest rate swap transactions generally involve the exchange of fixed and floating interest rate payment obligations without the exchange of underlying principal amounts. Swaps may be designated as either cash flow hedges or fair value hedges, as discussed below. As of June 30, 2018 and December 31, 2017, Synovus had no outstanding interest rate swap contracts utilized to manage interest rate risk related to core banking activities.

Synovus is party to master netting arrangements with its dealer counterparties; however, Synovus does not offset assets and liabilities under these arrangements for financial statement presentation purposes.

Counterparty Credit Risk and Collateral

Entering into derivative contracts potentially exposes Synovus to the risk of counterparties’ failure to fulfill their legal obligations, including, but not limited to, potential amounts due or payable under each derivative contract. Notional principal amounts are often used to express the volume of these transactions, but the amounts potentially subject to credit risk are much smaller. Synovus assesses the credit risk of its dealer counterparties by regularly monitoring publicly available credit rating information, evaluating other market indicators, and periodically reviewing detailed financials. Dealer collateral requirements are determined via risk-based policies and procedures and in accordance with existing agreements. Synovus seeks to minimize dealer credit risk by dealing with highly rated counterparties and by obtaining collateral for exposures above certain predetermined limits. Management closely monitors credit conditions within the customer swap portfolio, which management deems to be of higher risk than dealer counterparties. Collateral is secured at origination and credit related fair value adjustments are recorded against the asset value of the derivative as deemed necessary based upon an analysis, which includes consideration of the current asset value of the swap, customer credit rating, collateral value, and customer standing with regards to its swap contractual obligations and other related matters. Such asset values fluctuate based upon changes in interest rates regardless of changes in notional amounts and changes in customer specific risk.

34

Customer Related Derivative Positions

Synovus enters into interest rate swap agreements to facilitate the risk management strategies of a small number of commercial banking customers. Synovus mitigates this risk by entering into equal and offsetting interest rate swap agreements with highly rated counterparties. The interest rate swap agreements are free-standing derivatives and are recorded at fair value on Synovus' consolidated balance sheet. Fair value changes are recorded as a component of non-interest income. As of June 30, 2018, the notional amount of customer related interest rate derivative financial instruments, including both the customer position and the offsetting position, was $1.67 billion, an increase of $201.4 million compared to December 31, 2017.

Visa Derivative

In conjunction with the sale of Class B shares of common stock issued by Visa to Synovus as a Visa USA member, Synovus entered into a derivative contract with the purchaser, which provides for settlements between the parties based upon a change in the ratio for conversion of Visa Class B shares to Visa Class A shares. The conversion ratio changes when Visa deposits funds to a litigation escrow established by Visa to pay settlements for certain litigation, for which Visa is indemnified by Visa USA members. The litigation escrow is funded by proceeds from Visa’s conversion of Class B shares. The fair value of the derivative contract was $5.9 million and $4.3 million at June 30, 2018 and December 31, 2017, respectively. The fair value of the derivative contract is determined based on management's estimate of the timing and amount of the Covered Litigation settlement, and the resulting payments due to the counterparty under the terms of the contract. During the three months ended June 30, 2018, Synovus recorded a $2.3 million valuation adjustment to the Visa derivative following Visa's announcement on June 26, 2018 that it would deposit $600 million into its litigation escrow account. Management believes that the estimate of Synovus' exposure to the Visa indemnification and fees associated with the Visa derivative is adequate based on current information, including Visa's recent announcements and disclosures. However, future developments in the litigation could require potentially significant changes to Synovus' estimate. See "Part II - Item 8. Financial Statements and Supplementary Data - Note 18 - Visa Shares and Related Agreements" of Synovus' 2017 Form 10-K for further information.

Mortgage Derivatives

Synovus originates first lien residential mortgage loans for sale into the secondary market. Mortgage loans are sold by Synovus for conversion to securities and the servicing of these loans is generally sold to a third-party servicing aggregator, or Synovus sells the mortgage loans as whole loans to investors either individually or in bulk on a servicing released basis.

Synovus enters into interest rate lock commitments for residential mortgage loans which commits it to lend funds to a potential borrower at a specific interest rate and within a specified period of time. Interest rate lock commitments that relate to the origination of mortgage loans that, if originated, will be held for sale, are considered derivative financial instruments under applicable accounting guidance. Outstanding interest rate lock commitments expose Synovus to the risk that the price of the mortgage loans underlying the commitments may decline due to increases in mortgage interest rates from inception of the rate lock to the funding of the loan.

At June 30, 2018 and December 31, 2017, Synovus had commitments to fund at a locked interest rate, primarily fixed-rate mortgage loans to customers in the amount of $69.7 million and $49.3 million, respectively. Fair value adjustments related to these commitments resulted in a gain of $366 thousand and a loss of $(416) thousand for the six months ended June 30, 2018 and 2017, respectively, which was recorded as a component of mortgage banking income in the consolidated statements of income.

At June 30, 2018 and December 31, 2017, outstanding commitments to sell primarily fixed-rate mortgage loans amounted to $86.0 million and $72.5 million, respectively. Such commitments are entered into to reduce the exposure to market risk arising from potential changes in interest rates, which could affect the fair value of mortgage loans held for sale and outstanding rate lock commitments, which guarantee a certain interest rate if the loan is ultimately funded or granted by Synovus as a mortgage loan held for sale. The commitments to sell mortgage loans are at fixed prices and are scheduled to settle at specified dates that generally do not exceed 90 days. Fair value adjustments related to these outstanding commitments to sell mortgage loans resulted in a loss of $(119) thousand and $(1.7) million for the six months ended June 30, 2018 and 2017, respectively, which were recorded as a component of mortgage banking income in the consolidated statements of income.

Collateral Requirements

Pursuant to the Dodd-Frank Act, certain derivative transactions have collateral requirements, both at the inception of the trade and as the value of each derivative position changes. As of June 30, 2018, collateral totaling $30.6 million of federal funds sold was pledged to the derivative counterparties to comply with collateral requirements. Effective January 3, 2017, the CME amended its rulebook to legally characterize variation margin cash payments for cleared OTC derivatives as settlement rather than as collateral. As a result, in 2017, Synovus began reducing the corresponding derivative asset and liability balances for CME-cleared OTC derivatives to reflect the settlement of those positions via the exchange of variation margin. At June 30, 2018 and December 31, 2017, Synovus had a variation margin of $8.9 million and $1.5 million, respectively, reducing the derivative asset.

Note 10 - Net Income Per Common Share

The following table displays a reconciliation of the information used in calculating basic and diluted earnings per common share for the six and three months ended June 30, 2018 and 2017.

	Six Months Ended June 30,				Three Months Ended June 30,
(in thousands, except per share data)	2018		2017		2018		2017
Basic Net Income Per Common Share:
Net income available to common shareholders	$	209,229	$	142,742	$	108,622	$	73,444
Weighted average common shares outstanding	118,531		122,251		118,397		122,203
Net income per common share, basic	$	1.77	$	1.17	$	0.92	$	0.60
Diluted Net Income Per Common Share:
Net income available to common shareholders	$	209,229	$	142,742	$	108,622	$	73,444
Weighted average common shares outstanding	118,531		122,251		118,397		122,203
Potentially dilutive shares from outstanding equity-based awards and Earnout Payments	698		792		742		824
Weighted average diluted common shares	119,229		123,043		119,139		123,027
Net income per common share, diluted	$	1.75	$	1.16	$	0.91	$	0.60

Basic net income per common share is computed by dividing net income by the average common shares outstanding for the period. Diluted net income per common share reflects the dilution that could occur if securities or other contracts to issue common stock were exercised or converted. The dilutive effect of outstanding stock options and restricted share units is reflected in diluted net income per common share, unless the impact is anti-dilutive, by application of the treasury stock method.

As of June 30, 2018 and 2017, there were 2.2 million potentially dilutive shares related to the Warrant to purchase shares of common stock that were outstanding during 2018 and 2017 but were not included in the computation of diluted net income per common share because the effect would have been anti-dilutive.

Note 11 - Share-based Compensation

General Description of Share-based Plans

Synovus has a long-term incentive plan under which the Compensation Committee of the Board of Directors has the authority to grant share-based awards to Synovus employees. The 2013 Omnibus Plan authorizes 8.6 million common share equivalents available for grant, where grants of options count as one share equivalent and grants of full value awards (e.g., restricted share units, market restricted share units, and performance share units) count as two share equivalents. Any restricted share units that are forfeited and options that expire unexercised will again become available for issuance under the Plan. At June 30, 2018, Synovus had a total of 4.9 million shares of its authorized but unissued common stock reserved for future grants under the 2013 Omnibus Plan. The Plan permits grants of share-based compensation including stock options, restricted share units, market restricted share units, and performance share units. The grants generally include vesting periods ranging from three to five years and contractual terms of ten years. Vesting for grants made in 2018 accelerates upon retirement for plan participants who have reached age 65 and who also have no less than 10 years of service at the date of their election to retire. Market restricted share units and performance share units are granted at a defined target level and are compared annually to required market and performance metrics to determine actual units vested and compensation expense. Synovus has historically issued new shares to satisfy share option exercises and share unit conversions. Dividend equivalents are paid on outstanding restricted share units, market restricted share units, and performance share units in the form of additional restricted share units that vest over the same vesting period or the vesting period left on the original restricted share unit grant.

Share-based Compensation Expense

Total share-based compensation expense was $8.3 million and $4.4 million for the six and three months ended June 30, 2018, respectively, and $6.8 million and $3.5 million for the six and three months ended June 30, 2017, respectively. Accelerated share-based compensation expense associated with the provision in 2018 of a retirement vesting provision was approximately $200 thousand and $30 thousand for the six and three months ended June 30, 2018 for retirement eligible employees.

Stock Options

No stock option grants were made during the six months ended June 30, 2018. At June 30, 2018, there were 655 thousand outstanding stock options to purchase shares of common stock with a weighted average exercise price of $16.92 per share.

Restricted Share Units, Performance Share Units, and Market Restricted Share Units

During the six months ended June 30, 2018, Synovus awarded 234 thousand restricted share units that have a service-based vesting period of three years and awarded 87 thousand performance share units that vest upon service and performance conditions. Synovus also granted 58 thousand market restricted share units during the six months ended June 30, 2018. The weighted average grant-date fair value of the awarded restricted share units, performance share units and market restricted share units was $47.67 per share. Market restricted share units and performance share units are granted at target and are compared annually to required market and performance metrics. The performance share units vest upon meeting certain service and performance conditions. Return on average assets (ROAA) and return on average tangible common equity (ROATCE) performance is evaluated each year over a three-year performance period, with share distribution determined at the end of the three years. The number of performance share units that will ultimately vest ranges from 0% to 150% of target based on Synovus' three-year weighted average ROAA (as defined) and ROATCE (as defined). The market restricted share units have a three-year service-based vesting component as well as a total shareholder return multiplier. The number of market restricted share units that will ultimately vest ranges from 75% to 125% of target based on Synovus' total shareholder return. At June 30, 2018, including dividend equivalents granted, there were 910 thousand restricted share units, performance share units and market restricted share units outstanding with a weighted average grant-date fair value of $40.82 per share.

⁽¹⁾ Other revenues primarily relate to revenues not derived from contracts with customers.

Following is a discussion of key revenues within the scope of the new revenue guidance:

Service Charges on Deposit Accounts: Revenue from service charges on deposit accounts is earned through cash management, wire transfer, and other deposit-related services, as well as overdraft, non-sufficient funds, account management and other deposit-related fees. Revenue is recognized for these services either over time, corresponding with deposit accounts' monthly cycle, or at a point in time for transaction related services and fees. Payment for service charges on deposit accounts is primarily received immediately or in the following month through a direct charge to customers' accounts.

Fiduciary and Asset Management Fees: Fiduciary and asset management fees are primarily comprised of fees earned from the management and administration of trusts and other customer assets. Synovus' performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based upon the month-end market value of the assets under management and the applicable fee rate. Payment is generally received a few days after month-end through a direct charge to customers' accounts. Synovus does not earn performance-based incentives.

Card Fees: Card fees consist primarily of interchange fees from consumer credit and debit cards processed by card association networks, as well as merchant discounts, and other card related services. Interchange rates are generally set by the credit card associations and based on purchase volumes and other factors. Interchange fees and merchant discounts are recognized concurrently with the delivery of service on a daily basis as transactions occur. Payment is typically received immediately or in the following month. Card fees are reported net of certain associated expense items including loyalty program expenses and network expenses.

40

Brokerage Revenue: Brokerage revenue consists primarily of commissions. Additionally, brokerage revenue includes advisory fees earned from the management of customer assets. Advisory fees for brokerage services are recognized and collected monthly and are based upon the month-end market value of the assets under management at a rate predetermined in the contract. Transactional revenues are based on the size and number of transactions executed at the client's direction and are generally recognized on the trade date with payment received on the settlement date.

Insurance Revenue: Insurance revenue primarily consists of commissions received on annuity and life product sales. The commissions are recognized as revenue when the customer executes an insurance policy with the insurance carrier. In some cases, Synovus receives payment of trailing commissions each year when the customer pays its annual premium. For the six and three months ended June 30, 2018, Synovus recognized an immaterial amount of insurance trailing commissions related to performance obligations satisfied in prior periods.

Other Fees: Other fees primarily consist of revenues generated from safe deposit box rental fees and lockbox services. Fees are recognized over time, on a monthly basis, as Synovus' performance obligation for services is satisfied. Payment is received upfront for safe deposit box rentals and in the following month for lockbox services.

Contract Balances

A contract asset balance occurs when an entity performs a service for a customer before the customer pays consideration (resulting in a contract receivable) or before payment is due (resulting in a contract asset). A contract liability balance is an entity's obligation to transfer a service to a customer for which the entity has already received payment (or payment is due) from the customer. Synovus' non-interest revenue streams are largely based on transactional activity, or standard month-end revenue accruals such as asset management fees based on month-end market values. Consideration is often received immediately or shortly after Synovus satisfies its performance obligation and revenue is recognized. Synovus does not typically enter into long-term revenue contracts with customers, and therefore, does not experience significant contract balances. As of June 30, 2018 and December 31, 2017, Synovus did not have any significant contract balances.

Note 13 - Commitments and Contingencies

In the normal course of business, Synovus enters into commitments to extend credit such as loan commitments and letters of credit to meet the financing needs of its customers. Synovus uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee.

The contractual amount of these financial instruments represents Synovus' maximum credit risk should the counterparty draw upon the commitment, and should the counterparty subsequently fail to perform according to the terms of the contract. Since many of the commitments are expected to expire without being drawn upon, total commitment amounts do not necessarily represent future cash requirements. Additionally, certain commitments (primarily consumer) may generally be canceled by providing notice to the borrower.

41

The allowance for credit losses associated with unfunded commitments and letters of credit is a component of the unfunded commitments reserve recorded within other liabilities on the consolidated balance sheet. Additionally, unearned fees relating to letters of credit are recorded within other liabilities on the consolidated balance sheet. These amounts are not material to Synovus' consolidated balance sheet.

Unfunded letters of credit and lending commitments at June 30, 2018 and December 31, 2017 are presented below.

(in thousands)	June 30, 2018		December 31, 2017
Letters of credit*	$	179,860	$	153,372
Commitments to fund commercial and industrial loans	5,361,671		5,090,827
Commitments to fund commercial real estate, construction, and land development loans	1,652,834		1,567,583
Commitments under home equity lines of credit	1,179,074		1,137,714
Unused credit card lines	743,376		779,254
Other loan commitments	365,861		351,358
Total unfunded lending commitments and letters of credit	$	9,482,676	$	9,080,108

* Represent the contractual amount net of risk participations of approximately $70 million and $77 million at June 30, 2018 and December 31, 2017, respectively.

Merchant Services

In accordance with credit and debit card association rules, Synovus sponsors merchant processing servicers that process credit and debit card transactions on behalf of various merchants. In connection with these services, a liability may arise in the event of a billing dispute between the merchant and a cardholder that is ultimately resolved in the cardholder's favor. If the merchant defaults on its obligation to reimburse the cardholder, the cardholder, through its issuing bank, generally has until six months after the date of the transaction to present a chargeback to the merchant processor, which is primarily liable for any losses on covered transactions. However, if the merchant processor fails to meet its obligation to reimburse the cardholder for disputed transactions, then Synovus, as the sponsor, could be held liable for the disputed amount. Synovus mitigates this risk through its contractual arrangements with the merchant processing servicers and the merchants and by withholding future settlements, by retaining cash reserve accounts or by obtaining other security. During the six months ended June 30, 2018 and 2017, the sponsored entities processed and settled $34.35 billion and $30.42 billion, respectively, in total transactions. For the six months ended June 30, 2018 and 2017, Synovus incurred an immaterial amount of losses in connection with these chargebacks. During July 2018, Synovus began to accrue a receivable for chargebacks associated with one merchant processing relationship.

Legal Proceedings

Synovus and its subsidiaries are subject to various legal proceedings and claims that arise in the ordinary course of its business. Additionally, in the ordinary course of business, Synovus and its subsidiaries are subject to regulatory examinations, information gathering requests, inquiries and investigations. Synovus, like many other financial institutions, has been the target of numerous legal actions and other proceedings asserting claims for damages and related relief for losses. These actions include claims and counterclaims asserted by individual borrowers related to their loans and allegations of violations of state and federal laws and regulations relating to banking practices, including putative class action matters. In addition to actual damages, if Synovus does not prevail in asserted legal actions, credit-related litigation could result in additional write-downs or charge-offs of loans, which could adversely affect Synovus' results of operations during the period in which the write-down or charge-off were to occur.

Synovus carefully examines and considers each legal matter, and, in those situations where Synovus determines that a particular legal matter presents loss contingencies that are both probable and reasonably estimable, Synovus establishes an appropriate accrual. An event is considered to be probable if the future event is likely to occur. While the final outcome of any legal proceeding is inherently uncertain, based on the information currently available, advice of counsel and available insurance coverage, management believes that the amounts accrued with respect to legal matters as of June 30, 2018 are adequate. The actual costs of resolving legal claims may be higher or lower than the amounts accrued.

In addition, where Synovus determines that there is a reasonable possibility of a loss in respect of legal matters, Synovus considers whether it is able to estimate the total reasonably possible loss or range of loss. An event is “reasonably possible” if “the chance of the future event or events occurring is more than remote but less than likely.” An event is “remote” if “the chance of the future event or events occurring is more than slight but less than reasonably possible." In many situations, Synovus may be unable to estimate reasonably possible losses due to the preliminary nature of the legal matters, as well as a variety of other factors and uncertainties. For those legal matters where Synovus is able to estimate a range of reasonably possible losses,

42

management currently estimates the aggregate range from our outstanding litigation is from zero to $5 million in excess of the amounts accrued, if any, related to those matters. This estimated aggregate range is based upon information currently available to Synovus, and the actual losses could prove to be lower or higher. As there are further developments in these legal matters, Synovus will reassess these matters, and the estimated range of reasonably possible losses may change as a result of this assessment. Based on Synovus' current knowledge and advice of counsel, management presently does not believe that the liabilities arising from these legal matters will have a material adverse effect on Synovus' consolidated financial condition, results of operations or cash flows. However, it is possible that the ultimate resolution of these legal matters could have a material adverse effect on Synovus' results of operations for any particular period.

Synovus intends to vigorously pursue all available defenses to these legal matters, but will also consider other alternatives, including settlement, in situations where there is an opportunity to resolve such legal matters on terms that Synovus considers to be favorable, including in light of the continued expense and distraction of defending such legal matters. Synovus maintains insurance coverage, which may be available to cover legal fees, or potential losses that might be incurred in connection with such legal matters. The above-noted estimated range of reasonably possible losses does not take into consideration insurance coverage which may or may not be available for the respective legal matters.

Note 14 - Subsequent Events

Pending Acquisition of FCB Financial Holdings, Inc.

On July 23, 2018, Synovus entered into the Merger Agreement by and among Synovus, FCB and Azalea Merger Sub Corp.  pursuant to which Synovus will acquire FCB in a reverse triangular merger. At the effective time of the Merger, each outstanding share of FCB Class A common stock, par value $0.001 per share, will be converted into the right to receive, without interest, 1.055 shares of Synovus common stock, par value $1.00 per share.  The Merger Agreement has been unanimously approved by both companies’ Board of Directors.  The transaction is subject to customary closing conditions, including approval of Synovus and FCB shareholders and approval of state and federal regulators, and is expected to close by the first quarter of 2019. 

FCB operates 50 full service banking centers through its wholly-owned banking subsidiary, Florida Community Bank.  Following closing, Florida Community Bank will merge with and into Synovus Bank and operate under the Synovus brand.   

Redemption of Series C Preferred Stock

On August 1, 2018, Synovus redeemed all 5,200,000 outstanding shares of Series C Preferred Stock for a cash price of $25.00 per share, without interest, for an aggregate redemption price of $130 million and paid a dividend of $2.6 million on the Series C Preferred Stock. The redemption of the Series C Preferred Stock was funded primarily with proceeds from Synovus' public offering of $200 million of Series D Preferred Stock completed on June 21, 2018. Concurrent with the redemption, Synovus will recognize an extinguishment loss of $4.1 million to net income available to common shareholders. The $4.1 million extinguishment loss will be recognized in a manner similar to the treatment of dividends paid on preferred stock during the three months ending September 30, 2018.

(18) the impact on our financial results, reputation, and business if we are unable to comply with all applicable federal and state regulations or other supervisory actions or directives and any necessary capital initiatives;

Results for the Six and Three Months EndedJune 30, 2018

Net income available to common shareholders for the first six months of 2018 was $209.2 million, or $1.75 per diluted common share, an increase of 46.6% and 51.3%, respectively, compared to the first six months of 2017. Net income available to common shareholders for the second quarter of 2018 was $108.6 million, or $0.91 per diluted common share, an increase of 47.9% and 52.7%, respectively, compared to the second quarter of 2017. Return on average assets for the six months ended June 30, 2018 was 1.38%, up 40 basis points from the same period of 2017, and return on average assets for the second quarter of 2018 was 1.42%, up 42 basis points from the second quarter of 2017. Results for the first half of 2018 were driven by revenue growth and also reflect the benefit from a lower effective tax rate, due to the reduction of the Federal tax rate.

Total revenues, excluding investment securities losses, for the first half of 2018 were $700.6 million, up 12.3% compared to the same period in 2017. Total revenues, excluding investment securities losses, for the second quarter were $359.3 million, up 12.3% compared to the second quarter a year ago. Net interest income for the first half of 2018 was $558.9 million, an increase of $67.8 million, or 13.8%, compared to $491.0 million for the same period in 2017. The net interest margin was 3.82% for the six months ended June 30, 2018, an increase of 36 basis points from 3.46% for the six months ended June 30, 2017. The yield on earning assets was 4.39%, up 46 basis points compared to the six months ended June 30, 2017 and the effective cost of funds increased 10 basis points to 0.57%. The yield on loans was 4.79%, an increase of 48 basis points from the six months ended June 30, 2017 and the yield on investment securities was 2.34%, an increase of 25 basis points from the six months ended June 30, 2017. On a sequential quarter basis, net interest income increased by $10.3 million and the net interest margin increased by 8 basis points to 3.86%. The yield on earning assets was 4.47%, up 16 basis points from the first quarter of 2018. This increase was driven by an 18 basis point increase in loan yields. The effective cost of funds was 0.61% for the second quarter of 2018, up 8 basis points from the first quarter of 2018. The recent rate increases favorably impacted net interest income and net interest margin for 2018.

Non-interest income for the first six months of 2018 was $140.4 million compared to $140.5 million for the first six months of 2017. Non-interest income for the second quarter of 2018 was $73.4 million, up $4.7 million, or 6.8%, compared to the second quarter of 2017. Adjusted non-interest income, which excludes investment securities gains (losses) and decrease in fair value of private equity investments, was up $8.8 million, or 6.5%, for the first six months of 2018 compared to 2017 and up $4.7 million, or 6.7%, for the second quarter of 2018 compared to the second quarter of 2017. Synovus experienced growth in multiple categories during the first half of 2018 compared to the same time period in 2017 including an increase of $6.6 million, or 16.0%, in combined fiduciary and asset management fees, brokerage, and insurance revenues. See "Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Non-GAAP Financial Measures" of this Report for applicable reconciliation to GAAP measure.

Non-interest expense for the first six months of 2018 increased $10.1 million, or 2.6%, compared to the first six months of 2017 and non-interest expense for the second quarter of 2018 increased $12.3 million, or 6.4%, compared to the second quarter of 2017. The second quarter of 2018 included a $2.3 million expense for a valuation adjustment to the Visa derivative, offset in part by a $1.4 million benefit from a recovery of litigation settlement expense. The first quarter of 2018 included a $2.6 million reduction in litigation contingency accruals and the first quarter of 2017 included $6.5 million in restructuring charges. Adjusted non-interest expense, which excludes valuation adjustment to Visa derivative, restructuring charges, net, amortization of intangibles, and litigation settlement/contingency expense, increased $18.5 million, or 4.8%, for the first half of 2018 compared to the first half of 2017. Strong operating leverage for the first half of 2018 resulted in an efficiency ratio of 56.97%, improved from 62.31% for the first half of 2017. The adjusted efficiency ratio for the first six months of 2018 was 56.90%, down 397 basis points from the same period a year ago. See "Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Non-GAAP Financial Measures" of this Report for applicable reconciliation to GAAP measures.

Credit quality metrics continued to be favorable during the second quarter of 2018 with a reduction in both the non-performing loan ratio and non-performing asset ratio. Non-performing loans were $117.3 million at June 30, 2018, down $2.8 million, or 2.3%, from the prior quarter and down $42.0 million from June 30, 2017. The non-performing loan ratio was 0.47% at June 30, 2018, as compared to 0.48% in the prior quarter and 0.65% a year ago. Total non-performing assets were $126.3 million at June 30, 2018, down $4.8 million, or 3.7%, from the prior quarter and down $52.6 million, or 29.4%, from a year ago. The non-performing assets ratio was 0.50% at June 30, 2018, down 3 basis points from the prior quarter and down 23 basis points from a year ago. Net charge-offs for the six months ended June 30, 2018 were $22.1 million, or 0.18% as a percentage of average loans annualized, compared to $22.6 million, or 0.19%, as a percentage of average loans annualized for the six months ended June 30, 2017. Loans past due over 90 days were 0.01% of total loans at June 30, 2018 as compared to 0.02% at June 30, 2017. For the six months ended June 30, 2018, the provision for loan losses was $24.6 million, an increase of $5.6 million, or 29.7%, compared to the six months ended June 30, 2017. The increase in provision expense for the six months ended June 30, 2018 compared to the six months ended June 30, 2017 is primarily due to loan growth as well as a slightly increased level of charge-offs above reserves.The allowance for loan losses at June 30, 2018 was $251.7 million, or 1.00% of total loans, compared to $249.3 million, or 1.01% of total loans, at December 31, 2017 and $248.1 million, or 1.02% of total loans, at June 30, 2017.

49

At June 30, 2018, total loans were $25.13 billion, an increase of $346.6 million, or 2.8% annualized, and $703.5 million or 2.9%, compared to December 31, 2017 and June 30, 2017, respectively. Year-over-year loan growth was driven by a $532.5 million or 4.5% increase in C&I loans and a $945.8 million or 17.9% increase in consumer loans, with our lending partnerships growing $744.4 million and mortgage loans growing $280.3 million. This growth was partially offset by a $778.1 million or 10.5% decline in CRE loans.

During the second quarter of 2018, total average deposits increased $480.0 million, or 7.5% annualized, compared to the first quarter of 2018, and increased $1.28 billion, or 5.1%, compared to the second quarter of 2017. Average brokered deposits declined $29.0 million compared to the prior quarter. Average core deposits, during the second quarter of 2018, increased $509.0 million, or 8.6% annualized, compared to the prior quarter, and increased $733.0 million, or 3.1%, compared to the second quarter of 2017. During the first quarter of 2018, Synovusobtained FDIC approval to report deposits related to our sweep money market product, offered by Synovus Securities, as a component of core deposits. This product was reported as a brokered deposit through February of 2018. The second quarter average balance in these accounts totaled $310.0 million, and resulted in an increase of $198.0 million in average core deposits for the quarter, due to the reclassification. See “Non-GAAP Financial Measures” in this Report for the applicable reconciliation to the most comparable GAAP measure.

On June 21, 2018, Synovus completed a public offering of $200 million of Fixed-to-Floating Rate Non-Cumulative Perpetual Preferred Stock, Series D. The offering generated net proceeds of $195 million, which were largely used to fund the redemption of all of the outstanding shares of Series C Preferred Stock on August 1, 2018 for an aggregate redemption price of $130 million.

On January 23, 2018, Synovus announced a share repurchase program of up to $150 million to be completed during 2018.

⁽¹⁾ Percentage changes are annualized

At June 30, 2018, total loans were $25.13 billion, an increase of $346.6 million, or 2.8% annualized, and $703.5 million or 2.9%, compared to December 31, 2017 and June 30, 2017, respectively. Year-over-year loan growth was driven by a $532.5 million or 4.5% increase in C&I loans and a $945.8 million or 17.9% increase in consumer loans, with our lending partnerships growing $744.4 million and mortgage loans growing $280.3 million. This growth was partially offset by a $778.1 million or 10.5% decline in CRE loans.

Commercial Loans

Total commercial loans (which are comprised of C&I and CRE loans) at June 30, 2018 were $18.92 billion or 75.3% of the total loan portfolio, compared to $18.96 billion, or 76.5%, at December 31, 2017 and $19.17 billion, or 78.4%, at June 30, 2017.

At June 30, 2018 and December 31, 2017, Synovus had 30 and 25, respectively, commercial loan relationships with total commitments of $50 million or more (including amounts funded). The average funded balance of these relationships was approximately $35 million for both June 30, 2018 and December 31, 2017.

Commercial and Industrial Loans

The C&I loan portfolio represents the largest category of Synovus' total loan portfolio. The following table shows the composition of the C&I portfolio aggregated by NAICS code. The portfolio is relationship focused and, as a result, Synovus' lenders have in-depth knowledge of the borrowers, most of which have guaranty arrangements. C&I loans are originated through Synovus' local markets and the Corporate Banking Group to commercial customers primarily to finance capital expenditures, including real property, plant and equipment, or as a source of working capital. In accordance with Synovus' lending policy, each loan undergoes a detailed underwriting process which incorporates uniform underwriting standards and oversight in proportion to the size and complexity of the lending relationship. As of June 30, 2018, approximately 93% of Synovus' C&I loans are secured by real estate, business equipment, inventory, and other types of collateral. C&I loans of $12.28 billion, representing 48.8% of the total loan portfolio, grew $251.8 million, or 4.2% annualized, from December 31, 2017 and$532.5 million, or 4.5%, from June 30, 2017. The growth in C&I loans was broad-based, driven by small business, premium finance, and senior housing.

⁽¹⁾ Loan balance in each category expressed as a percentage of total C&I loans.

At June 30, 2018, $7.27 billion of C&I loans, or 28.9% of the total loan portfolio, represented loans originated for the purpose of financing commercial, financial, and agricultural business activities. The primary source of repayment on these loans is revenue generated from products or services offered by the business or organization. The secondary source of repayment is the collateral, which consists primarily of equipment, inventory, accounts receivable, time deposits, cash surrender value of life insurance, and other business assets.

At June 30, 2018, $5.00 billion of C&I loans, or 19.9% of the total loan portfolio, represented loans originated for the purpose of financing owner-occupied properties. The financing of owner-occupied facilities is considered a C&I loan even though there is improved real estate as collateral. This treatment is a result of the credit decision process, which focuses on cash flow from operations of the business to repay the debt. The secondary source of repayment on these loans is the underlying real estate. These loans are predominately secured by owner-occupied and other real estate, and to a lesser extent, other types of collateral.

Commercial Real Estate Loans

Total CRE loans consist of investment properties loans, 1-4 family properties loans, as well as land and development loans. These loans are subject to the same uniform lending policies referenced above. CRE loans of $6.64 billion, representing 26.4% of the total loan portfolio, decreased $291.1 million, or 8.5% annualized, from December 31, 2017 and decreased $778.1 million, or 10.5%, from June 30, 2017. The $291.1 million decline was driven by a $160.5 million decrease in the Investment Properties portfolio and a $69.7 million decrease in the non-strategic Land and Development portfolio. The decline in CRE is largely the result of the continued higher velocity of pay-off activity across the portfolio.

Investment Properties Loans

Investment properties loans consist of construction and mortgage loans for income producing properties and are primarily made to finance multi-family properties, hotels, office buildings, shopping centers, warehouses, and other commercial development properties. Total investment properties loans as of June 30, 2018 were $5.51 billion, or 82.9% of the total CRE portfolio and 21.9% of the total loan portfolio, compared to $5.67 billion, or 81.8% of the total CRE portfolio and 22.9% of the total loan portfolio at December 31, 2017, a decrease of $160.5 million, or 5.7% annualized primarily due to a decline in office buildings and multi-family properties. Synovus' investment properties portfolio is well diversified by property type, geography (primarily within Synovus' primary market areas of Georgia, Alabama, South Carolina, Florida, and Tennessee), and tenants. The investment properties loans are primarily secured by the property being financed by the loans; however, these loans may also be secured by real estate or other assets beyond the property being financed.

1-4 Family Properties Loans

1-4 family properties loans include construction loans to homebuilders and commercial mortgage loans to real estate investors and are almost always secured by the underlying property being financed by such loans. These properties are primarily located

52

in the markets served by Synovus. Construction loans are generally interest-only loans and typically have maturities of three years or less, and commercial mortgage loans generally have maturities of three to five years, with amortization periods of up to fifteen to twenty years. At June 30, 2018, 1-4 family properties loans totaled $720.7 million, or 10.8% of the total CRE portfolio and 2.9% of the total loan portfolio, compared to $781.6 million, or 11.3% of the total CRE portfolio and 3.2% of the total loan portfolio at December 31, 2017.

Land and Development Loans

Land and development loans include commercial and residential development as well as land acquisition loans and are secured by land held for future development, typically in excess of one year. These loans have short-term maturities and are typically unamortized. Properties securing these loans are substantially within the Synovus footprint, and loan terms generally include personal guarantees from the principals. Loans in this portfolio are underwritten based on the LTV of the collateral and the capacity of the guarantor(s). Total land and development loans were $413.9 million at June 30, 2018, or 1.6% of the total loan portfolio, a decline of $69.7 million, or 29.1% annualized, from December 31, 2017. Synovus continues to strategically reduce its exposure to these types of loans.

Consumer Loans

The consumer loan portfolio consists of a wide variety of loan products offered through Synovus' banking network as well as third-party lending partnerships, including first and second residential mortgages, home equity lines, credit card loans, home improvement loans, student loans, and other consumer loans. The majority of Synovus' consumer loans are consumer mortgages and home equity lines secured by first and second liens on residential real estate primarily located in the markets served by Synovus.

Consumer loans at June 30, 2018 totaled $6.24 billion, representing 24.8% of the total loan portfolio compared to $5.85 billion, or 23.6% of the total loan portfolio at December 31, 2017, and $5.29 billion, or 21.7% of the total loan portfolio at June 30, 2017. Consumer loans increased $383.3 million, or 13.2% annualized, from December 31, 2017 and $945.8 million, or 17.9%, from June 30, 2017. Consumer mortgages grew $117.4 million or 9.0% annualized, from December 31, 2017, and $280.3 million, or 11.3%, from June 30, 2017 given solid production in the private wealth management and physician categories as well as the continued addition of mortgage loan originators. HELOCs decreased $60.4 million or 8.0% from December 31, 2017. Credit card loans totaled $238.4 million at June 30, 2018, including $67.8 million of commercial credit card loans.

Other consumer loans increased $320.5 million, or 43.9% annualized, from December 31, 2017, and $762.3 million, or 73.9%, from June 30, 2017 primarily due to two consumer-based lending partnerships. One lending partnership, which began in the third quarter of 2015, is a program that provides merchants and contractors nationwide with the ability to offer term financing to their customers for major purchases and home improvement projects. The other lending partnership, which began in the second quarter of 2016, primarily provides qualified borrowers the ability to refinance student loan debt. As of June 30, 2018, these partnerships had combined balances of $1.4 billion, or 5.7% of the total loan portfolio.

Consumer loans, including those through our lending partnerships, are subject to uniform lending policies and consist primarily of loans with strong borrower credit scores. Synovus makes consumer lending decisions based upon a number of key credit risk determinants including FICO scores as well as loan-to-value and debt-to-income ratios. Risk levels 1-6 (descending) are assigned to consumer loans based upon a risk score matrix. At least annually, the consumer loan portfolio data is sent to a consumer credit reporting agency for a refresh of customers' credit scores so that management can evaluate ongoing consistency or negative migration in the quality of the portfolio, which impacts the allowance for loan losses. The most recent credit score refresh was completed as of December 31, 2017. Revolving lines of credit were reviewed for any material change in financial circumstances, and when appropriate, the line of credit may be suspended for further advances. FICO scores within the residential real estate portfolio have generally remained stable over the last several years.

As of the most recent FICO score refresh on March 31, 2018, weighted-average FICO scores within the residential real estate portfolio were 774 for HELOCs and 785 for consumer mortgages.HELOC utilization rates (total amount outstanding as a percentage of total available lines) were 53.7% and 55.6% atJune 30, 2018andDecember 31, 2017, respectively. Additionally, we maintained loan-to-value ratios based upon prudent guidelines to ensure consistency with Synovus' overall risk philosophy. At June 30, 2018, 35% of home equity line balances were secured by a first lien, and 65% were secured by a second lien. Apart from credit card loans and unsecured loans, Synovus does not originate loans with LTV ratios greater than 100% at origination except for infrequent situations provided that certain underwriting requirements are met. Additionally, at origination, loan maturities are determined based on the borrower's ability to repay (cash flow or earning power that represents the primary source of repayment) and the collateralization of the loan, including the economic life of the asset being pledged. Collateral securing these loans provides a secondary source of repayment in that the collateral may be liquidated. Synovus determines the need for collateral on a case-by-case basis. Factors considered include the purpose of the loan, current and prospective credit-worthiness of the customer, terms of the loan, and economic conditions.

Higher-risk consumer loans as defined by the FDIC are consumer loans (excluding consumer loans defined as nontraditional mortgage loans) where, as of the origination date or, if the loan has been refinanced, as of the refinance date, the probability of

53

default within two years is greater than 20%, as determined using a defined historical stress period. These loans are not a part of Synovus' consumer lending strategy, and Synovus does not currently develop or offer specific sub-prime, alt-A, no documentation or stated income residential real estate loan products. Synovus estimates that, as of June 30, 2018, it had $83.7 million of higher-risk consumer loans (1.3% of the consumer portfolio and 0.3% of the total loan portfolio) compared to $100.7 million as of June 30, 2017. Included in these amounts as of June 30, 2018 and 2017 are approximately $9 million and $12 million, respectively, of accruing TDRs.

During the second quarter of 2018, total average deposits increased $480.0 million, or 7.5% annualized, compared to the first quarter of 2018, and increased $1.28 billion, or 5.1%, compared to the second quarter of 2017. Average brokered deposits declined $29.0 million compared to the prior quarter. Average core deposits, during the second quarter of 2018, increased $509.0 million, or 8.6% annualized, compared to the prior quarter, and increased $733.0 million, or 3.1%, compared to the second quarter of 2017. During the first quarter of 2018, Synovusobtained FDIC approval to report deposits related to our sweep money market product, offered by Synovus Securities, as a component of core deposits. This product was reported as a brokered deposit through February of 2018. The second quarter average balance in these accounts totaled $310.0 million, and resulted in an increase of $198.0 million in average core deposits for the quarter, due to the reclassification. See “Non-GAAP Financial Measures” in this Report for the applicable reconciliation to the most comparable GAAP measure.

Average non-interest bearing demand deposits as a percentage of total average deposits were 28.7% for both the three months ended June 30, 2018 and three months ended March 31, 2018 and 29.2% for the three months ended June 30, 2017.

Average time deposits of $100,000 and greater for the three months ended June 30, 2018, March 31, 2018, and June 30, 2017 were $3.68 billion, $3.42 billion, and $2.86 billion, respectively, and included average brokered time deposits of $1.66 billion, $1.53 billion, and $815.5 million, respectively. These larger deposits represented 14.0%, 13.3%, and 11.4% of total average deposits for the three months ended June 30, 2018, March 31, 2018, and June 30, 2017, respectively, and included brokered time deposits which represented 6.3%, 5.9%, and 3.3% of total average deposits for the three months ended June 30, 2018, March 31, 2018, and June 30, 2017, respectively.

During the second quarter of 2018, total average brokered deposits represented 7.3% of total average deposits compared to 7.6% and 5.5% of total average deposits the previous quarter and the second quarter a year ago, respectively.

Non-interest Income

Non-interest income for the first six months of 2018 was $140.4 million compared to $140.5 million for the first six months of 2017. Non-interest income for the second quarter of 2018 was $73.4 million, up $4.7 million, or 6.8%, compared to the second quarter of 2017. Adjusted non-interest income, which excludes investment securities gains (losses) and decrease in fair value of private equity investments, was up $8.8 million, or 6.5%, for the first six months of 2018 compared to 2017 and up $4.7 million, or 6.7%, for the second quarter of 2018 compared to the second quarter of 2017. Synovus experienced growth in multiple categories during the first half of 2018 compared to the same time period in 2017 including an increase of $6.6 million, or 16.0%, in combined fiduciary and asset management fees, brokerage, and insurance revenues. See "Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Non-GAAP Financial Measures" of this Report for applicable reconciliation to GAAP measure.

Principal Components of Non-interest Income

Service charges on deposit accounts for the six and three months ended June 30, 2018 were down $432 thousand, or 1.1%, and down $253 thousand, or 1.2%, respectively, compared to the six and three months ended June 30, 2017. Service charges on deposit accounts consist of NSF fees, account analysis fees, and all other service charges. NSF fees for the six and three months ended June 30, 2018 were down $267 thousand, or 1.5%, and $241 thousand, or 2.7%, respectively, compared to the six and three months ended June 30, 2017. Account analysis fees for the six and three months ended June 30, 2018 were up $171 thousand, or 1.4%, and $284 thousand, or 4.6%, respectively, compared to the six and three months ended June 30, 2017. All other service charges on deposit accounts, which consist primarily of monthly fees on retail demand deposit and saving accounts, for the six and three months ended June 30, 2018 were down $336 thousand, or 3.3%, and $297 thousand, or 5.8%, compared to the same periods in 2017.

Fiduciary and asset management fees are derived from providing estate administration, personal trust, corporate trust, corporate bond, investment management, and financial planning services. Fiduciary and asset management fees increased $2.7 million, or 11.1%, and $1.5 million, or 11.6%, for the six and three months ended June 30, 2018, respectively, compared to the six and three months ended June 30, 2017. The increase was driven by growth in assets under management. Total assets under management (including brokerage assets under management) increased by 16% year-over-year to approximately $14.4 billion, due to overall market conditions, increased productivity as well as the addition of new talent.

Card fees totaled $21.0 million and $10.8 million for the six and three months ended June 30, 2018, respectively, compared to $19.9 million and $10.0 million for the same periods in 2017. Card fees consist primarily of credit card interchange fees, debit card interchange fees, and merchant discounts. Card fees are reported net of certain associated expense items including customer loyalty program expenses and network expenses.

Brokerage revenue was $17.6 million and $8.9 million for the six and three months ended June 30, 2018, respectively, up $3.2 million, or 21.9%, and up $1.7 million, or 23.4%, compared to the six and three months ended June 30, 2017, respectively. The increase in 2018 from 2017 was largely driven by growth in brokerage assets under management due primarily to new talent additions. Brokerage revenue consists primarily of brokerage commissions. Additionally, brokerage revenue includes advisory fees earned from the management of customer assets.

55

Mortgage banking income decreased $1.7 million, or 14.4%, and $945 thousand, or 16.3%, compared to the six and three months ended June 30, 2017, respectively, reflecting softer production volume in a rising interest rate environment.

Income from bank-owned life insurance increased $1.6 million, or 25.6%, and $461 thousand, or 14.1%, compared to the six and three months ended June 30, 2017, respectively, due to additional investments in bank-owned life insurance policies during the first quarter of 2017, increases in the cash surrender value of these policies, and death benefits.

Investment securities losses of $1.3 million for the six and three months ended June 30, 2018 included a loss of $1.3 million from a strategic sale to improve portfolio performance. Investment securities gains, net of $7.7 million for the six months ended June 30, 2017 included a $3.4 million gain on the sale of an equity position and a $4.3 million gain from the repositioning of the investment securities portfolio during the first quarter of 2017.

Private equity investments consist of an equity method investment in a venture capital fund. The net loss of $3.1 million for the first half of 2018 consisted mostly of net unrealized losses on certain investments within the fund. The net loss of $3.2 million during the first half of 2017 consisted mostly of realized losses on sales of investments within the fund.

Other fee income includes fees for letters of credit and unused lines of credit, safe deposit box fees, access fees for automated teller machine use, customer swap dealer fees, and other service charges. Other fee income was lower by $1.2 million, or 10.5%, and $905 thousand, or 14.7%, compared to the six and three months ended June 30, 2017, respectively, due primarily to higher customer swap dealer fees and syndication arranger fees in 2017.

The main components of other non-interest income are income from insurance commissions, gains from sales of GGL/SBA loans, and other miscellaneous items. Other non-interest income was up $3.4 million, or 43.3%, and $2.4 million, or 49.2%, compared to the six and three months ended June 30, 2017, respectively, due primarily to higher insurance commissions, higher gains on sales of GGL/SBA loans, and miscellaneous items.

Non-interest Expense

Non-interest expense for the first six months of 2018 increased $10.1 million, or 2.6%, compared to the first six months of 2017 and non-interest expense for the second quarter of 2018 increased $12.3 million, or 6.4%, compared to the second quarter of 2017. The second quarter of 2018 included a $2.3 million expense for a valuation adjustment to the Visa derivative offset in part by a $1.4 million benefit from a recovery of litigation settlement expense. The first quarter of 2018 included a $2.6 million reduction in litigation contingency accruals and the first quarter of 2017 included $6.5 million in restructuring charges. Adjusted non-interest expense, which excludes valuation adjustment to Visa derivative, restructuring charges, net, amortization of intangibles, and litigation settlement/contingency expense increased $18.5 million, or 4.8%, for the first half of 2018 compared to the first half of 2017. Strong operating leverage for the first half of 2018 resulted in an efficiency ratio of 56.97%, improved from 62.31% for the first half of 2017. The adjusted efficiency ratio for the first six months of 2018 was 56.90%, down 397 basis points from the same period a year ago. See "Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Non-GAAP Financial Measures" of this Report for applicable reconciliation to GAAP measures.

The following table summarizes the components of non-interest expense.

Total non-interest expense	$	399,234		$	389,133	2.6	%	$	204,057		$	191,747	6.4	%

Salaries and other personnel expenses increased $13.2 million, or 6.2%, and $6.7 million, or 6.3%, for the six and three months ended June 30, 2018, respectively, compared to the same periods in 2017, primarily due to talent additions and higher incentive compensation expense.

Net occupancy and equipment expense increased $4.9 million, or 8.2%, and $2.7 million, or 9.1%, during the six and three months ended June 30, 2018, respectively, compared to the same periods in 2017 driven primarily by costs associated with growth in technology investments.

Third-party processing expense includes all third-party core operating system and processing charges as well as third-party servicing charges. Third-party processing expense increased $2.8 million, or 10.6%, and $1.4 million, or 10.6%, during the six and three months ended June 30, 2018, respectively, compared to the same periods in 2017. The increase is primarily due to an increase of $2.5 million and $1.1 million for the six and three months ended June 30, 2018, respectively, compared to the same periods in 2017, from servicing fees associated with loan growth from Synovus' two consumer-based lending partnerships.

During the three months ended June 30, 2018, Synovus recorded a $2.3 million valuation adjustment to the Visa derivative following Visa's announcement on June 26, 2018 that it would deposit $600 million into its litigation escrow account.

For the six months ended June 30, 2018, Synovus recorded net lease termination accrual reversals of $377 thousand related to branches closed in prior years offset somewhat by other property related charges of $165 thousand. During the six months ended June 30, 2017, Synovus recorded severance charges of $6.5 million including $6.2 million for termination benefits incurred in conjunction with a voluntary early retirement program offered to Synovus employees during the first quarter of 2017.

Other operating expenses for the six and three months ended June 30, 2018 included a benefit of $4.0 million and $1.4 million, respectively, from recoveries and reductions in litigation contingency accruals. Other operating expenses for the six and three months ended June 30, 2017 included a $2.4 million gain from the settlement of a contingent receivable.

Income Tax Expense

Income tax expense was $61.1 million and $30.9 million for the six and three months ended June 30, 2018, respectively, representing an effective tax rate of 22.2% and 21.8% for the respective periods. Income tax expense was $75.6 million and $41.8 million for the six and three months ended June 30, 2017, respectively, representing an effective tax rate of 33.8% and 35.5% for the respective periods. The effective tax rate is lower for the six and three months ended June 30, 2018 due to Federal Tax Reform that reduced the federal statutory rate from 35% to 21% for tax years beginning after December 31, 2017.

The effective tax rate is affected by many factors including, but not limited to, the level of pre-tax income, bank-owned life insurance, tax-exempt interest and nondeductible expenses. In addition, the effective tax rate is affected by items that may occur in any given period but are not consistent from period-to-period, such as tax benefits related to share-based compensation, jurisdiction statutory tax rate changes, valuation allowance changes and changes to unrecognized tax benefits. Accordingly, the comparability of the effective tax rate between periods may be impacted.

The effective income tax rate for the six months ended June 30, 2018 included a net discrete income tax benefit of $2.8 million predominantly resulting from tax benefits associated with the exercise and vesting of employee equity awards.

CREDIT QUALITY, CAPITAL RESOURCES AND LIQUIDITY

Credit Quality

Synovus continuously monitors the quality of its loan portfolio by industry, property type, geography, as well as credit quality metrics and maintains an allowance for loan losses that management believes is sufficient to absorb probable losses inherent in its loan portfolio. Credit quality metrics have remained favorable during the first six months of 2018.

The table below includes selected credit quality metrics.

⁽¹⁾ Represent only impaired loans that have been specifically identified to be sold. Impaired loans held for sale are carried at the lower of cost or fair value, less costs to sell, based primarily on estimated sales proceeds net of selling costs.

Non-performing Assets

Total NPAs were $126.3 million at June 30, 2018, a $4.2 million, or 3.3%, decrease from $130.6 million at December 31, 2017 and a $52.6 million, or 29.4%, decrease from $178.9 million at June 30, 2017. The year-over-year decline in non-performing assets was driven by the continued resolution of problem assets, including accelerated dispositions in conjunction with the balance sheet restructuring actions in the third quarter of 2017. Total non-performing assets as a percentage of total loans, other loans held for sale, and other real estate were 0.50% at June 30, 2018 compared to 0.53% at December 31, 2017 and 0.73% at June 30, 2017.

Troubled Debt Restructurings

Accruing TDRs were $125.3 million at June 30, 2018, compared to $151.3 million at December 31, 2017 and $167.4 million at June 30, 2017. Accruing TDRs declined $26.0 million, or 17.2%, from December 31, 2017 and $42.1 million, or 25.1%, from a year ago primarily due to continued decline in TDR inflows, fewer loans qualifying for removal of TDR designation upon subsequent renewal, refinance, or modification, and pay-offs.

At June 30, 2018, the allowance for loan losses allocated to these accruing TDRs was $6.5 million compared to $8.7 millionat December 31, 2017 and $8.5 million at June 30, 2017. Accruing TDRs are considered performing because they are performing in accordance with the restructured terms. At June 30, 2018 and December 31, 2017, 97% and 99%, respectively, of accruing TDRs were current. In addition, subsequent defaults on accruing TDRs (defaults defined as the earlier of the TDR being placed on non-accrual status or reaching 90 days past due with respect to principal and/or interest payments within twelve months of the TDR designation) have remained at low levels. There were eight defaults for the six months ended June 30, 2018 and three defaults for the six months ended June 30, 2017.

Non-accruing TDRs were $30.4 million at June 30, 2018 compared to $11.7 million at December 31, 2017. Non-accruing TDRs generally may be returned to accrual status if there has been a period of performance, consisting usually of at least a six month sustained period of repayment performance in accordance with the terms of the agreement.

Potential Problem Loans

Potential problem loans are defined by management as being certain performing loans with a well-defined weakness where there is known information about possible credit problems of borrowers which causes management to have concerns about the ability of such borrowers to comply with the present repayment terms of such loans. Potential problem commercial loans consist of commercial Substandard accruing loans but exclude loans 90 days past due and still accruing interest and accruing TDRs

58

classified as Substandard since these loans are disclosed separately. Potential problem commercial loans were $153.5 million at June 30, 2018 compared to $103.3 million and $149.2 million at December 31, 2017 and June 30, 2017, respectively. Synovus cannot predict whether these potential problem loans ultimately will become non-performing loans or result in losses.

Net Charge-offs

Net charge-offs for the six months ended June 30, 2018 were $22.1 million, or 0.18% as a percentage of average loans annualized, compared to $22.6 million, or 0.19%, as a percentage of average loans annualized for the six months ended June 30, 2017.

Provision for Loan Losses and Allowance for Loan Losses

For the six months ended June 30, 2018, the provision for loan losses was $24.6 million, an increase of $5.6 million, or 29.7%, compared to the six months ended June 30, 2017. The increase in provision expense for the six months ended June 30, 2018 compared to the six months ended June 30, 2017 is primarily due to loan growth as well as a slightly increased level of charge-offs above reserves.

The allowance for loan losses at June 30, 2018 was $251.7 million, or 1.00% of total loans, compared to $249.3 million, or 1.01% of total loans, at December 31, 2017 and $248.1 million, or 1.02% of total loans, at June 30, 2017.

Capital Resources

Synovus and Synovus Bank are required to comply with capital adequacy standards established by their primary federal regulator, the Federal Reserve. Synovus and Synovus Bank measure capital adequacy using the standardized approach to the Basel III Final Rule. Synovus has always placed great emphasis on maintaining a solid capital base and continues to satisfy applicable regulatory capital requirements.

At June 30, 2018, Synovus and Synovus Bank's capital levels remained strong and each exceeded well-capitalized requirements currently in effect. The following table presents certain ratios used to measure Synovus and Synovus Bank's capitalization.

The Basel III capital rules became effective January 1, 2015 for Synovus and Synovus Bank, subject to a transition period for several aspects, including the capital conservation buffer and certain regulatory capital adjustments and deductions, as described below. Under the Basel III capital rules, the minimum capital requirements for Synovus and Synovus Bank include a common equity Tier 1 (CET1) ratio of 4.5%; Tier 1 capital ratio of 6%; total capital ratio of 8%; and leverage ratio of 4%. When fully phased-in on January 1, 2019, the Basel III capital rules include a capital conservation buffer of 2.5% that is added on top of each of the minimum risk-based capital ratios. The implementation of the capital conservation buffer began on January 1, 2016 at the 0.625% level and will be phased-in over a three-year period (increasing by that amount on each subsequent January 1 until it reaches 2.5% on January 1, 2019). As a financial holding company, Synovus and its subsidiary bank, Synovus Bank, are required to maintain capital levels required for a well-capitalized institution as defined by federal banking regulations. Under the Basel III capital rules, Synovus and Synovus Bank are well-capitalized if each has a CET1 ratio of 6.5% or greater, a Tier 1 risk-based capital ratio of 8% or greater, a total risk-based capital ratio of 10% or greater, a leverage ratio of 5% or greater, and are not subject to any written agreement, order, capital directive, or prompt corrective action directive from a federal and/or state banking regulatory agency to meet and maintain a specific capital level for any capital measure.

On June 21, 2018, Synovus completed a public offering of $200 million of Fixed-to-Floating Rate Non-Cumulative Perpetual Preferred Stock, Series D. The offering generated net proceeds of $195 million, which were largely used to fund the redemption of all of the outstanding shares of Series C Preferred Stock on August 1, 2018 for an aggregate redemption price of $130 million.

On January 23, 2018, Synovus announced a share repurchase program of up to $150 million to be completed during 2018. As of June 30, 2018, Synovus had repurchased under this program a total of $76.8 million, or 1.5 million shares of its common stock, at an average price of $52.72 per share. As of June 30, 2018 and August 6, 2018, the remaining authorization under this program was $73.2 million and $44.6 million, respectively.

As of June 30, 2018, total disallowed deferred tax assets were $63.6 million or 0.23% of risk-weighted assets, compared to $70.4 million, or 0.25% of risk-weighted assets, at December 31, 2017. Disallowed deferred tax assets for CET1 were $50.9 million at June 30, 2018 compared to $56.3 million at December 31, 2017. See "Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Income Taxes" in Synovus' 2017 Form 10-K for more information on Synovus' net deferred tax asset.

At June 30, 2018, Synovus' CET1 ratio was 10.12% under the Basel III transitional provisions, and the estimated fully phased-in CET1 ratio was 10.06%, both of which are well in excess of regulatory requirements including the capital conservation buffer. On November 21, 2017, federal banking regulators adopted a final rule to extend the regulatory capital transition for certain items applicable during 2017 to future periods for banking organizations (such as Synovus) that are not subject to the advanced approaches capital rule. This reduced the capital impact to Synovus in 2018 from the fully phased-in implementation of Basel III that was originally required. See "Non-GAAP Financial Measures" in this Report for the applicable reconciliation to the most comparable GAAP measure. Management currently believes, based on internal capital analyses and earnings projections, that Synovus' capital position is adequate to meet current and future regulatory minimum capital requirements.

Dividends

Synovus has historically paid a quarterly cash dividend to the holders of its common stock. Management and the Board of Directors closely monitor current and projected capital levels, liquidity (including dividends from subsidiaries), financial markets and other economic trends, as well as regulatory requirements regarding the payment of dividends. During the first quarter of 2018, Synovus increased the quarterly common stock dividend by 67% to $0.25 per share effective with the quarterly dividend declared during the first quarter of 2018.

Synovus' ability to pay dividends on its capital stock, consisting of the common stock and the preferred stock, is primarily dependent upon dividends and distributions that it receives from its bank and non-banking subsidiaries, which are restricted by various regulations administered by federal and state bank regulatory authorities, as further discussed below. During the six months ended June 30, 2018, Synovus Bank paid upstream cash dividends to Synovus totaling $110.0 million. For the year ended December 31, 2017, Synovus Bank and non-bank subsidiaries made upstream cash distributions to the Parent Company totaling $451.0 million including cash dividends of $283.2 million.

    Synovus declared dividends of $0.50 and $0.30 per common share for the six months ended June 30, 2018 and six months ended June 30, 2017, respectively. In addition to dividends paid on its common stock, Synovus paid dividends of $5.1 million on its Series C Preferred Stock during both the six months ended June 30, 2018 and 2017.

On June 21, 2018, Synovus completed a public offering of $200 million of Fixed-to-Floating Rate Non-Cumulative Perpetual Preferred Stock, Series D. The offering generated net proceeds of $195 million, which were largely used to fund the redemption of all of the outstanding shares of Series C Preferred Stock on August 1, 2018 for an aggregate redemption price of $130 million.

Liquidity

Liquidity represents the extent to which Synovus has readily available sources of funding needed to meet the needs of depositors, borrowers and creditors, to support asset growth, and to otherwise sustain operations of Synovus and its subsidiaries, at a reasonable cost, on a timely basis, and without adverse consequences. ALCO monitors Synovus' economic, competitive, and regulatory environment and is responsible for measuring, monitoring, and reporting on liquidity and funding risk, interest rate risk, and market risk and has the authority to establish policies relative to these risks. ALCO, operating under liquidity and funding policies approved by the Board of Directors, actively analyzes contractual and anticipated cash flows in order to properly manage Synovus’ liquidity position.

Contractual and anticipated cash flows are analyzed under normal and stressed conditions to determine forward looking liquidity needs and sources. Synovus analyzes liquidity needs under various scenarios of market conditions and operating performance. This analysis includes stress testing and measures expected sources and uses of funds under each scenario. Emphasis is placed on maintaining numerous sources of current and potential liquidity to allow Synovus to meet its obligations to depositors, borrowers, and creditors on a timely basis.

Liquidity is generated primarily through maturities and repayments of loans by customers, maturities and sales of investment securities, deposit growth, and access to sources of funds other than deposits. Management continuously monitors and maintains appropriate levels of liquidity so as to provide adequate funding sources to manage customer deposit withdrawals, loan requests, and funding maturities. Liquidity is also enhanced by the acquisition of new deposits. Each of the local markets monitors deposit flows and evaluates local market conditions in an effort to retain and grow deposits.

Synovus Bank also generates liquidity through the national deposit markets through the issuance of brokered certificates of deposit and money market accounts. Synovus Bank accesses these funds from a broad geographic base to diversify its sources of funding and liquidity. On September 25, 2017, Synovus Bank completed the Cabela's Transaction and thereby retained WFB's $1.10 billion brokered time deposit portfolio with a weighted average remaining maturity of approximately 2.53 years and a weighted average rate of 1.83 percent. Synovus Bank has the capacity to access funding through its membership in the FHLB system. At June 30, 2018, based on currently pledged collateral, Synovus Bank had access to incremental funding of $1.26 billion, subject to FHLB credit policies, through utilization of FHLB advances.

60

In addition to bank level liquidity management, Synovus must manage liquidity at the parent company level for various operating needs including the servicing of debt, the payment of dividends on our common stock and preferred stock, share repurchases, payment of general corporate expenses and potential capital infusions into subsidiaries. The primary source of liquidity for Synovus consists of dividends from Synovus Bank, which is governed by certain rules and regulations of the GA DBF and the Federal Reserve Bank. During the six months ended June 30, 2018, Synovus Bank paid upstream cash dividends to Synovus totaling $110.0 million. For the year ended December 31, 2017, Synovus Bank and non-bank subsidiaries made upstream cash distributions to the Parent Company totaling $451.0 million including cash dividends of $283.2 million. Synovus' ability to receive dividends from Synovus Bank in future periods will depend on a number of factors, including, without limitation, Synovus Bank's future profits, asset quality, liquidity, and overall condition. In addition, GA DBF rules and related statutes contain limitations on payments of dividends by Synovus without the approval of the GA DBF.

On June 21, 2018, Synovus completed a public offering of $200 million of Fixed-to-Floating Rate Non-Cumulative Perpetual Preferred Stock, Series D. The offering generated net proceeds of $195 million, which were largely used to fund the redemption of all of the outstanding shares of Series C Preferred Stock on August 1, 2018 for an aggregate redemption price of $130 million.

On November 1, 2017, Synovus issued $300.0 million aggregate principal amount of 3.125% senior notes maturing in 2022 in a public offering with aggregate proceeds of $296.9 million, net of discount and debt issuance costs. On November 9, 2017, Synovus redeemed all of the $300.0 million aggregate principal amount of its 7.875% senior notes due 2019 at a "make whole" premium. 2017 results included a loss of $23.2 million related to early extinguishment of these notes. Additionally, during 2017, Synovus paid off the remaining balance of $278.6 million of its subordinated notes at their maturity date of June 15, 2017.

Synovus presently believes that the sources of liquidity discussed above, including existing liquid funds on hand, are sufficient to meet its anticipated funding needs. However, if economic conditions were to significantly deteriorate, regulatory capital requirements for Synovus or Synovus Bank increase as the result of regulatory directives or otherwise, or Synovus believes it is prudent to enhance current liquidity levels, then Synovus may seek additional liquidity from external sources. See "Part I – Item 1A. Risk Factors - Changes in the cost and availability of funding due to changes in the deposit market and credit market may adversely affect our capital resources, liquidity and financial results." ofSynovus' 2017 Form 10-K. Furthermore, Synovus may, from time to time, take advantage of attractive market opportunities to refinance its existing debt, redeem its preferred stock, which is redeemable beginning on August 1, 2018, or strengthen its liquidity or capital position.

Earning Assets and Sources of Funds

Average total assets for the six months ended June 30, 2018 increased $838.0 million or 2.7%, to $31.37 billion as compared to $30.54 billion for the first six months of 2017. Average earning assets increased $968.6 million, or 3.4%, in the first six months of 2018 compared to the same period in 2017 and represented 94.3% of average total assets at June 30, 2018, as compared to 93.7% at June 30, 2017. The increase in average earning assets resulted from a $708.9 million increase in average loans, net, and a $242.8 million increase in average taxable investment securities. Average interest bearing liabilities increased $632.9 million, or 3.1%, to $20.76 billion for the first six months of 2018 compared to the same period in 2017. The increase in average interest bearing liabilities was driven by a $672.8 million increase in average time deposits and a $206.0 million increase in average interest bearing demand deposits. These increases were partially offset by a $238.2 million decrease in average long-term debt. Average non-interest bearing demand deposits increased $229.1 million, or 3.2%, to $7.47 billion for the first six months of 2018 compared to the same period in 2017.

Net interest income for the six months ended June 30, 2018 was $558.9 million, an increase of $67.8 million, or 13.8%, compared to $491.0 million for the six months ended June 30, 2017.

The net interest margin was 3.82% for the six months ended June 30, 2018, an increase of 36 basis points from 3.46% for the six months ended June 30, 2017. The yield on earning assets was 4.39%, up 46 basis points compared to the six months ended June 30, 2017 and the effective cost of funds increased 10 basis points to 0.57%. The yield on loans was 4.79%, an increase of 48 basis points from the six months ended June 30, 2017 and the yield on investment securities was 2.34%, an increase of 25 basis points from the six months ended June 30, 2017.

On a sequential quarter basis, net interest income increased by $10.3 million and the net interest margin increased by 8 basis points to 3.86%. The increase in net interest income was driven by an $81.3 million increase in average loans, net. The increase in net interest income for the quarter was also driven by margin expansion. Additionally, the rate increases in March and June favorably impacted net interest income and the net interest margin for the three months ended June 30, 2018 compared to the previous quarter. The yield on earning assets was 4.47%, up 16 basis points from the first quarter of 2018. This increase was driven by an 18 basis point increase in loan yields. The effective cost of funds was 0.61% for the second quarter of 2018, up 8 basis points from the first quarter of 2018.

Market Risk Analysis

Interest rate risk is the primary market risk to which Synovus is potentially exposed. Synovus measures its sensitivity to changes in market interest rates through the use of a simulation model. Synovus uses this simulation model to determine a baseline net interest income forecast and the sensitivity of this forecast to changes in interest rates. These simulations include all of Synovus’ earning assets and liabilities. Forecasted balance sheet changes, primarily reflecting loan and deposit growth forecasts, are included in the periods modeled. Anticipated deposit mix changes in each interest rate scenario are also included in the periods modeled. Assumptions utilized in the model are updated on an ongoing basis and are reviewed and approved by ALCO and the Risk Committee of the Board of Directors.

Synovus has modeled its baseline net interest income forecast assuming a flat interest rate environment with the federal funds rate at the Federal Reserve’s current targeted range of 1.75% to 2.00% and the current prime rate of 5.00%. Synovus has modeled the impact of a gradual increase in short-term rates of 100 and 200 basis points and a gradual decline of 100 basis points to determine the sensitivity of net interest income for the next twelve months. Synovus continues to maintain a modestly asset sensitive position which would be expected to benefit net interest income in a rising interest rate environment and reduce net interest income in a declining interest rate environment. The following table represents the estimated sensitivity of net interest income to these changes in short-term interest rates at June 30, 2018, with comparable information for December 31, 2017.

	Estimated % Change in Net Interest Income as Compared to Unchanged Rates (for the next twelve months)
Change in Short-term Interest Rates (in basis points)	June 30, 2018	December 31, 2017
+200	3.0%	3.6%
+100	1.4%	1.9%
Flat	—%	—%
-100	-3.7%	-4.7%

Several factors could serve to diminish or eliminate this asset sensitivity in a rising rate environment. These factors include a higher than projected level of deposit customer migration to higher cost deposits, such as certificates of deposit, which would increase total interest expense and serve to reduce the realized level of asset sensitivity. Another factor which could impact the realized interest rate sensitivity is the repricing behavior of interest bearing non-maturity deposits. Assumptions for repricing are expressed as a beta relative to the change in the prime rate. For instance, a 50% beta would correspond to a deposit rate that would increase 0.5% for every 1% increase in the prime rate. Projected betas for interest bearing non-maturity deposit repricing are a key component of determining the Company's interest rate risk positioning. Projected betas are based on historical analysis, current product features, and deposit mix. These projected betas reflect an assumption that realized betas will increase as short-term rates increase. Should realized betas be higher than projections, the expected benefit from higher interest rates would be diminished. The following table presents an example of the potential impact of an increase in repricing betas on Synovus' realized interest rate sensitivity position.

	As of June 30, 2018
Change in Short-term Interest Rates (in basis points)	Base Scenario	15% Increase in Average Repricing Beta
+200	3.0%	1.4%
+100	1.4%	0.7%

The net interest income simulation model is the primary tool utilized to evaluate potential interest rate risks over a shorter term time horizon. Synovus also evaluates potential longer term interest rate risk through modeling and evaluation of EVE. Simulation modeling is utilized to measure the economic value of equity and its sensitivity to immediate changes in interest rates. This EVE modeling allows Synovus to capture longer-term repricing risk and options risk embedded in the balance sheet. These simulations value only the current balance sheet and do not incorporate growth assumptions used in the net interest income simulation. The economic value of equity is the net fair value of assets, liabilities, and off-balance sheet financial instruments derived from the present value of future cash flows discounted at current market interest rates. From this baseline valuation, Synovus evaluates changes in the value of each of these items in various interest rate scenarios to determine the net impact on the economic value of equity. Key assumptions utilized in the model, namely loan prepayments, investment security prepayments, deposit repricing betas, and non-maturity deposit duration have a significant impact on the results of the EVE simulations. As illustrated in the table below, the EVE model indicates that, compared with a valuation assuming stable rates, EVE is projected to increase by 1.6% and by 1.5%, assuming an immediate and sustained increase in interest rates of 100 and 200 basis points, respectively. Assuming an immediate 100 basis point decline in rates, EVE is projected to decrease by 14.7%. These metrics reflect a relatively stable long term interest rate risk position as compared to December 31, 2017.

	Estimated Change in EVE
Immediate Change in Interest Rates (in basis points)	June 30, 2018	December 31, 2017
+200	1.5%	-0.2%
+100	1.6%	1.6%
-100	-14.7%	-16.9%

ADDITIONAL DISCLOSURES

Recently Issued Accounting Standards

Several accounting standards will be effective in fiscal year 2019 or later. Synovus is currently evaluating the requirements of these new ASUs to determine the impact on the consolidated financial statements:

• ASU 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities

• ASU 2017-08, Receivables-Nonrefundable Fees and Other Costs: Premium Amortization on Purchased Callable Debt Securities

• ASU 2017-04, Intangibles-Goodwill and Other, Simplifying the Test for Goodwill Impairment

• ASU 2016-13, Financial Instruments-Credit Losses (CECL)

• ASU 2016-02, Leases

The ASUs with the most significant impact on Synovus are ASU 2016-13, Financial Instruments-Credit Losses (CECL), effective in 2020 and ASU 2016-02, Leases, effective in 2019.

ASU 2016-13,Financial Instruments--Credit Losses (CECL).In June 2016, the FASB issued the new guidance related to credit losses. The new guidance replaces the existing incurred loss impairment guidance with an expected credit loss methodology. The new guidance will require management’s estimate of credit losses over the full remaining expected life of loans and other financial instruments. For Synovus, the standard will apply to loans, unfunded loan commitments, and debt securities available for sale. The standard is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted on January 1, 2019.  Upon adoption, Synovus will record a cumulative effect adjustment to retained earnings as of the beginning of the reporting period of adoption.  

Synovus has begun its implementation efforts which are led by a cross-functional steering committee.  Management expects that the allowance for loan losses will be higher under the new standard; however, management is still in the process of determining the magnitude of the impact on its financial statements and regulatory capital ratios.  Additionally, the extent of the expected increase on the allowance for loan losses will depend upon the composition of the loan portfolio upon adoption of the standard, as well as economic conditions and forecasts at that time.

ASU 2016-02,Leases.In February 2016, the FASB issued ASU 2016-02, its new standard on lease accounting. ASU 2016-02 introduces a lessee model that brings most leases on the balance sheet. Under the new standard, all lessees will recognize a right-of-use asset and a lease liability, including operating leases, with a lease term greater than 12 months. From a lessor perspective, the accounting model is largely unchanged, though the new standard does include certain targeted improvements to align, where necessary, lessor accounting with the lessee accounting model and the revenue recognition guidance in ASC Topic 606 (those related to evaluating when profit can be recognized). For Synovus, the impact of this ASU will primarily relate to its accounting and reporting of leases as a lessee. The new ASU will be effective for Synovus beginning January 1, 2019. Synovus will adopt this ASU retrospectively, at the beginning of the period of adoption, through a cumulative-effect adjustment to retained earnings. The standard also requires additional disclosures regarding leasing arrangements.

Synovus is currently evaluating the potential financial statement impact from the implementation of this standard by reviewing its existing lease contracts and other contracts that may include embedded leases. Synovus currently expects to recognize lease liabilities and corresponding right-of-use assets (at their present value) related to substantially all of the $230 million of future minimum lease commitments as disclosed in Note 7 of Synovus' 2017 Form 10-K. However, the population of contracts requiring balance sheet recognition and their initial measurement continues to be under evaluation.

See "Note 1 - Significant Accounting Policies" in this Report for a discussion of recently adopted accounting standards updates.

Critical Accounting Policies

The accounting and financial reporting policies of Synovus are in accordance with GAAP and conform to the accounting and reporting guidelines prescribed by bank regulatory authorities. Synovus has identified certain of its accounting policies as “critical accounting policies,” consisting of those related to the allowance for loan losses and determination of the fair value of financial instruments. In determining which accounting policies are critical in nature, Synovus has identified the policies that require significant judgment or involve complex estimates. It is management's practice to discuss critical accounting policies with the Board of Directors' Audit Committee, including the development, selection, implementation and disclosure of the critical accounting policies. The application of these policies has a significant impact on Synovus’ unaudited interim consolidated financial statements. Synovus’ financial results could differ significantly if different judgments or estimates are used in the application of these policies. All accounting policies described in "Part II - Item 8. Financial Statements and Supplementary Data - Note 1 - Summary of Significant Accounting Policies" in Synovus' 2017 Form 10-K should be reviewed for a greater understanding of how we record and report our financial performance. In connection with the adoption of ASU 2016-18, Statement of Cash Flows-Restricted Cash, Synovus changed its presentation of cash and cash equivalents, effective January 1, 2018, to include cash and due from banks as well as interest bearing funds with the Federal Reserve Bank, interest earning deposits with banks, and federal funds sold and securities purchased under resale agreements, which are inclusive of any restricted cash and restricted cash equivalents. Prior to 2018, cash and cash equivalents only included cash and due from banks. Prior periods have been revised to maintain comparability. Excluding the aforementioned presentation change, there have been no significant changes to the accounting policies, estimates and assumptions, or the judgments affecting the application of these estimates and assumptions from those disclosed in Synovus' 2017 Form 10-K.

Non-GAAP Financial Measures

The measures entitled adjusted non-interest income; adjusted non-interest expense; adjusted efficiency ratio; adjusted net income per common share, diluted; adjusted return on average assets; adjusted return on average common equity; adjusted return on average tangible common equity; average core deposits; tangible common equity ratio; and common equity Tier 1 (CET1) ratio (fully phased-in) are not measures recognized under GAAP and therefore are considered non-GAAP financial measures. The most comparable GAAP measures to these measures are total non-interest income; total non-interest expense; efficiency ratio; net income per common share, diluted; return on average assets; return on average common equity; total average deposits; the ratio of total shareholders' equity to total assets; and the CET1 ratio, respectively.

Management believes that these non-GAAP financial measures provide meaningful additional information about Synovus to assist management and investors in evaluating Synovus’ operating results, financial strength, the performance of its business, and the strength of its capital position. However, these non-GAAP financial measures have inherent limitations as analytical tools and should not be considered in isolation or as a substitute for analyses of operating results or capital position as reported under GAAP. The non-GAAP financial measures should be considered as additional views of the way our financial measures are affected by significant items and other factors, and since they are not required to be uniformly applied, they may not be comparable to other similarly titled measures at other companies. Adjusted non-interest income is a measure used by management to evaluate non-interest income exclusive of net investment securities gains/losses and changes in fair value of private equity investments, net. Adjusted non-interest expense and the adjusted efficiency ratio are measures utilized by management to measure the success of expense management initiatives focused on reducing recurring controllable operating costs. Adjusted net income per common share, diluted, adjusted return on average assets, and adjusted return on average common equity are measurements used by management to evaluate operating results exclusive of items that management believes are not indicative of ongoing operations and impact period-to-period comparisons. The adjusted return on average tangible common equity is a measure used by management to compare Synovus' performance with other financial institutions because it calculates the return available to common shareholders without the impact of intangible assets and their related amortization, thereby allowing management to evaluate the performance of the business consistently. Average core deposits is a measure used by management to evaluate organic growth of deposits and the quality of deposits as a funding source. The tangible common equity ratio and common equity Tier 1 (CET1) ratio (fully phased-in) are used by management and bank regulators to assess the strength of our capital position. The computations of these measures are set forth in the tables below.

ITEM 3. – QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The information presented in the Market Risk Analysis section of the Management's Discussion and Analysis of Financial Condition and Results of Operations is incorporated herein by reference.

ITEM 4. – CONTROLS AND PROCEDURES

In connection with the preparation of this Quarterly Report on Form 10-Q, an evaluation was carried out by Synovus' management, with the participation of Synovus' Chief Executive Officer and Chief Financial Officer, of the effectiveness of Synovus' disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Disclosure controls and procedures are designed to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and that such information is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosures. Based on that evaluation, Synovus' Chief Executive Officer and Chief Financial Officer have concluded that, as of June 30, 2018, Synovus' disclosure controls and procedures were effective.     

There have been no material changes in Synovus' internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that occurred during the quarter ended June 30, 2018 that have materially affected, or are reasonably likely to materially affect, Synovus' internal control over financial reporting.

71

PART II. – OTHER INFORMATION

ITEM 1. – LEGAL PROCEEDINGS

Synovus and its subsidiaries are subject to various legal proceedings, claims and disputes that arise in the ordinary course of its business. Additionally, in the ordinary course of its business, Synovus and its subsidiaries are subject to regulatory examinations, information gathering requests, inquiries and investigations. Synovus, like many other financial institutions, has been the target of legal actions and other proceedings asserting claims for damages and related relief for losses. These actions include mortgage loan and other loan put-back claims, claims and counterclaims asserted by individual borrowers related to their loans and allegations of violations of state and federal laws and regulations relating to banking practices, including putative class action matters. In addition to actual damages, if Synovus does not prevail in such asserted legal actions, credit-related litigation could result in additional write-downs or charge-offs of assets, which could adversely affect Synovus' results of operations during the period in which the write-down or charge-off were to occur.

Based on Synovus' current knowledge and advice of counsel, management presently does not believe that the liabilities arising from these legal matters will have a material adverse effect on Synovus' consolidated financial condition, results of operations or cash flows. However, it is possible that the ultimate resolution of these legal matters could have a material adverse effect on Synovus' results of operations and financial condition for any particular period. For additional information, see "Note 13 - Commitments and Contingencies" of this Report, which Note is incorporated herein by this reference.

ITEM 1A. – RISK FACTORS

In addition to the other information set forth in this Report, you should carefully consider the factors discussed in "Part I - Item IA - Risk Factors” of Synovus’ 2017 Form 10-K which could materially affect its business, financial position, results of operations, cash flows, or future results. Please be aware that these risks may change over time and other risks may prove to be important in the future. New risks may emerge at any time, and we cannot predict such risks or estimate the extent to which they may affect our business, financial condition or results of operations, or the trading price of our securities.

As a result of Synovus entering into the Merger Agreement with FCB, certain risk factors, as provided below, have been identified in addition to those previously reported in Synovus’ 2017 10-K. These risks and the other risks associated with the proposed Merger will be more fully discussed in the joint proxy statement/prospectus that will be included in the registration statement on Form S-4 that Synovus will file with the SEC in connection with the Merger. We urge you to read the registration statement on Form S-4 once it becomes available because it will contain important information about the Merger, including relevant risk factors.

The consummation of the Merger is contingent upon the satisfaction of a number of conditions, including shareholder and regulatory approvals, that are outside of our or FCB’s control and that we and FCB may be unable to satisfy or obtain or which may delay the consummation of the Merger or result in the imposition of conditions that could reduce the anticipated benefits from the Merger or cause the parties to abandon the Merger.

Consummation of the Merger is contingent upon the satisfaction of a number of conditions, some of which are beyond our and FCB’s control, including, among others: (i) the adoption of the Merger Agreement by the holders of FCB’s class A common stock, (ii) the approval of the issuance of shares of our common stock to be issued to the FCB stockholders in the Merger by our shareholders, (iii) the authorization for listing on the New York Stock Exchange of the shares our common stock to be issued to the FCB stockholders in the Merger, (iv) the effectiveness of the registration statement registering our common stock to be issued to FCB stockholders in the Merger, (v) the absence of any order, injunction or other legal restraint preventing the completion of the Merger or making the consummation of the Merger illegal and (vi) the receipt of required regulatory approvals, including the approval of the Board of Governors of the Federal Reserve System and the Georgia Department of Banking and Finance. Furthermore, each party’s obligation to complete the Merger is also subject to certain additional customary conditions, including (i) subject to certain exceptions, the accuracy of the representations and warranties of the other party, generally subject to a material adverse effect qualification, (ii) performance in all material respects by the other party of its obligations under the Merger Agreement and (iii) receipt by such party of an opinion from its counsel to the effect that the Merger will qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended.

These conditions to the closing of the Merger may not be fulfilled in a timely manner or at all, and, accordingly, the Merger may not be completed. In addition, the parties can mutually decide to terminate the Merger Agreement at any time, before or after receipt of the requisite approvals by our shareholders or FCB's stockholders, or we or FCB may elect to terminate the Merger Agreement in certain other circumstances.

72

In addition, we and FCB may be subject to lawsuits challenging the Merger, and adverse rulings in these lawsuits may delay or prevent the Merger from being completed or require us or FCB to incur significant costs to defend or settle these lawsuits. Any delay in completing the Merger could cause us not to realize, or to be delayed in realizing, some or all of the benefits that we expect it to achieve if the Merger is successfully completed within its expected time frame.

We may fail to realize all of the anticipated benefits of the Merger, or those benefits may take longer to realize than expected. We may also encounter significant difficulties in integrating FCB.

Our ability to realize the anticipated benefits of the Merger will depend, to a large extent, on our ability to successfully integrate the acquired businesses. The integration and combination of the acquired businesses is a complex, costly and time-consuming process. As a result, we will be required to devote significant management attention and resources to integrating their business practices and operations with ours. The integration process may disrupt our business and the business of FCB and, if implemented ineffectively, could limit the full realization of the anticipated benefits of the acquisition. The failure to meet the challenges involved in integrating the acquired businesses and to realize the anticipated benefits of the Merger could cause an interruption of, or a loss of momentum in, our business activities or those of FCB and could adversely impact our business, financial condition and results of operations. In addition, the overall integration of the businesses may result in material unanticipated problems, expenses, liabilities, loss of customers and diversion of our management’s and employees’ attention. The challenges of combining the operations of the companies include, among others:

• difficulties in achieving anticipated cost savings, synergies, business opportunities and growth prospects from the acquisition;

• difficulties in the integration of operations and systems;

• difficulties in the assimilation of employees;

• difficulties in managing the expanded operations of a larger and more complex company;

• challenges in keeping existing customers and obtaining new customers;

• challenges in attracting and retaining key personnel, including personnel that are considered key to the future success of FCB’s businesses; and

• challenges in keeping key business relationships in place.

Many of these factors will be outside of our control and any one of them could result in increased costs and liabilities, decreases in the amount of expected income and diversion of management’s time and energy, which could have a material adverse effect on our business, financial condition and results of operations.

In addition, even if the operations of FCB are integrated successfully with our business, the full benefits of the transaction may not be realized, including the synergies, cost savings, growth opportunities or earnings accretion that are expected. These benefits may not be achieved within the anticipated time frame, or at all, and additional unanticipated costs may be incurred in the integration of the businesses. Furthermore, FCB may have unknown or contingent liabilities that we would assume in the acquisition and that were not discovered during the course of our due diligence. These liabilities could include exposure to unexpected asset quality problems, compliance and regulatory violations, key employee and client retention problems and other problems that could result in significant costs to us.

All of these factors could cause dilution to our earnings per share, decrease or delay the expected accretive effect of the transaction, negatively impact the price of our common stock, or have a material adverse effect on our business, financial condition and results of operations.

Failure to complete the Merger could negatively impact our stock price and the future business and financial results.

Completion of the Merger is not assured. If the Merger is not completed, our ongoing business and financial results may be adversely affected and we will be subject to several risks, including the following:

• the price of our common stock may decline to the extent that current market prices reflect a market assumption that the Merger will be completed;

• having to pay significant costs relating to the Merger without receiving the benefits of the Merger, including, in certain circumstances, a termination fee of $93.5 million;

• negative reactions from customers, shareholders, market analysts, employees and future acquisition partners;

• the possible loss of employees necessary to operate our business;

• we will have been subject to certain restrictions on the conduct of our business, which may have prevented us from making certain acquisitions or dispositions or pursuing certain business opportunities while the Merger was pending; and

73

• the diversion of the focus of our management to the Merger instead of on pursuing other opportunities that could have been beneficial to us and our business.

If the Merger is not completed, we cannot assure our shareholders that these risks will not materialize and will not materially adversely affect our business, financial results, and stock price. Additionally, if the Merger is not completed, we will not recognize the anticipated benefits of the Merger, yet will still incur significant expenses.

While the Merger is pending, we will be subject to business uncertainties and contractual restrictions that could adversely affect our business and operations.

Uncertainty about the effect of the Merger on employees, customers and other persons with whom we or FCB have a business relationship may have an adverse effect on our business, operations and stock price. In connection with the pendency of the acquisition, existing customers of FCB could decide to no longer do business with FCB, reducing the anticipated benefits of the Merger. Synovus is also subject to certain restrictions on the conduct of its business while the Merger is pending. As a result, certain other projects may be delayed or ceased and business decisions could be deferred. Employee retention at FCB, and also at Synovus, may be challenging during the pendency of the Merger, as certain employees may experience uncertainty about their future roles with the combined company. If key employees depart because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with Synovus, FCB or the combined company, the benefits of the Merger could be materially diminished.

In addition, shareholders and market analysts could also have a negative perception of the Merger, which could cause a material reduction in our stock price and could also result in (i) our not achieving the requisite vote to approve the issuance of our shares in the Merger and/or (ii) FCB not achieving the requisite vote to adopt the Merger Agreement.

The Merger may not be accretive and may cause dilution of our adjusted earnings per share following the Merger, which may negatively affect the market price of our common stock.

We currently anticipate that the Merger will be accretive to shareholders of the combined company on an earnings per share basis in 2020. This expectation is based on preliminary estimates, which may materially change. We could also encounter additional transaction and integration-related costs or other factors resulting in the failure to realize all of the benefits anticipated in the Merger. All of these factors could cause dilution of our adjusted earnings per share or decrease or delay the expected accretive effect of the Merger and cause a decrease in the market value of our common stock.

We are expected to incur substantial expenses related to the Merger and our integration with FCB.

Both Synovus and FCB will incur substantial expenses in connection with the Merger and our integration with FCB. There are a large number of processes, policies, procedures, operations, technologies, and systems that must be integrated. While we have assumed that a certain level of expenses would be incurred, there are many factors beyond our control that could affect the total amount or the timing of the integration expenses. Moreover, many of the expenses that will be incurred are, by their nature, difficult to estimate accurately. These expenses could, particularly in the near term, exceed the savings that we expect to achieve from the elimination of duplicative expenses and the realization of economies of scale and cost savings. These integration expenses likely will result in us taking significant charges against earnings following the completion of the Merger, and the amount and timing of such charges are uncertain at present.

Our future results will suffer if we do not effectively manage our expanded operations following the Merger.

Following the Merger, the size of our business will increase significantly beyond its current size. Our future success depends, in part, upon our ability to manage this expanded business, which will pose substantial challenges for our management, including challenges related to the management and monitoring of new operations and associated increased costs and complexity. There can be no assurances we will be successful or that we will realize the expected operating efficiencies, cost savings and other benefits currently anticipated from the Merger.

Current Synovus shareholders may have a reduced ownership and voting interest in the combined company after the Merger.

Synovus expects to issue or reserve for issuance approximately 52 million shares of Synovus common stock to FCB stockholders in connection with the Merger (including shares of Synovus common stock to be issued in connection with outstanding FCB equity awards). Upon completion of the Merger, each Synovus shareholder will remain a shareholder of Synovus with a percentage ownership of the combined company that may be smaller than the shareholder's percentage of Synovus prior to the transaction, depending upon such shareholder's current ownership of Synovus shares. As a result of these potentially reduced ownership

percentages, Synovus shareholders may have less voting power in the combined company than they now have with respect to Synovus.

Accounting Policies [Abstract]

Significant Accounting Policies

Note 1 - Significant Accounting Policies

Business Operations

The accompanying unaudited interim consolidated financial statements of Synovus Financial Corp. include the accounts of the Parent Company and its consolidated subsidiaries. Synovus Financial Corp. is a financial services company based in Columbus, Georgia. Through its wholly-owned subsidiary, Synovus Bank, a Georgia state-chartered bank that is a member of the Federal Reserve System, the company provides commercial and retail banking in addition to a full suite of specialized products and services including private banking, treasury management, wealth management, premium finance and international banking.

Synovus Bank is positioned in some of the highest growth markets in the Southeast, with 250 branches and 334 ATMs in Georgia, Alabama, South Carolina, Florida, and Tennessee.

Basis of Presentation

The accompanying unaudited interim consolidated financial statements have been prepared in accordance with the instructions to the SEC Form 10-Q and Article 10 of Regulation S-X; therefore, they do not include all information and footnotes necessary for a fair presentation of financial position, results of operations, comprehensive income, and cash flows in conformity with GAAP. All adjustments consisting of normally recurring accruals that, in the opinion of management, are necessary for a fair presentation of the consolidated financial position and results of operations for the periods covered by this Report have been included. The accompanying unaudited interim consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes appearing in Synovus' 2017 Form 10-K.

In connection with the adoption of ASU 2016-18, Statement of Cash Flows-Restricted Cash, Synovus changed its presentation of cash and cash equivalents, effective January 1, 2018, to include cash and due from banks as well as interest bearing funds with the Federal Reserve Bank, interest earning deposits with banks, and federal funds sold and securities purchased under resale agreements, which are inclusive of any restricted cash and restricted cash equivalents. Prior to 2018, cash and cash equivalents only included cash and due from banks. Prior periods have been revised to maintain comparability. Excluding the aforementioned presentation change, there have been no significant changes to the accounting policies as disclosed in Synovus' 2017 Form 10-K.

In preparing the unaudited interim consolidated financial statements in accordance with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the respective consolidated balance sheets and the reported amounts of revenues and expenses for the periods presented. Actual results could differ significantly from those estimates.

Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses, the fair value of investment securities, and the fair value of private equity investments.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash and due from banks, interest bearing funds with the Federal Reserve Bank, interest earning deposits with banks, federal funds sold and securities purchased under resale agreements, and is inclusive of any restricted cash and restricted cash equivalents. Restricted cash and restricted cash equivalents primarily relate to cash held on deposit with the Federal Reserve to meet reserve requirements as well as cash posted as collateral for derivatives in a liability position. At June 30, 2018 and December 31, 2017, interest bearing funds with the Federal Reserve Bank included $35.7 million and $8.6 million, respectively, on deposit to meet Federal Reserve Bank requirements. Interest earning deposits with banks include $2.7 million and $5.9 million at June 30, 2018 and December 31, 2017, respectively, which are pledged as collateral in connection with certain letters of credit. Federal funds sold include $30.6 million and $43.8 million at June 30, 2018 and December 31, 2017, respectively, which are pledged to collateralize certain derivative financial instruments. Federal funds sold and securities purchased under resale agreements generally mature in one day.

Income Taxes

On December 22, 2017, Federal Tax Reform was enacted into law. The new legislation included a decrease in the corporate federal income tax rate from 35% to 21% effective January 1, 2018. Under ASC 740, the effects of the changes in tax rates and laws are recognized in the period in which the new legislation is enacted. Therefore, Synovus was required to remeasure its deferred tax assets and liabilities and record the adjustment to income tax expense effective December 22, 2017. In December 2017, the SEC issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (SAB 118), which allowed companies to record provisional amounts during a measurement period not to extend beyond one year of the enactment date. Since Federal Tax Reform was enacted late in 2017, management expects that certain deferred tax assets and liabilities will continue to be evaluated in the context of Federal Tax Reform through the date of the filing of our 2017 federal income tax return, and may change as a result of evolving management interpretations, elections, and assumptions, as well as new guidance that may be issued by the Internal Revenue Service.   Accordingly, the federal income tax expense of $47.2 million recorded in 2017 relating to the effects from Federal Tax Reform is considered provisional. Management expects to complete its analysis within the measurement period in accordance with SAB 118.  

Recently Adopted Accounting Standards Updates

ASU 2014-09, Revenue from Contracts with Customers (Topic 606) issued by the FASB in May 2014, and all subsequent ASUs that modified 606. ASU 2014-09 implements a common revenue standard that establishes principles for reporting information about the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts to provide goods or services to customers. The core principle of the revenue model is that a company will recognize revenue when it transfers control of goods or services to customers at an amount that reflects the consideration to which it expects to be entitled in exchange for those goods or services. The scope of the guidance explicitly excludes net interest income as well as many other revenues from financial assets. Management reviewed its revenue streams and contracts with customers and did not identify material changes to the timing or amount of revenue recognition. Synovus adopted these ASUs on the required effective date of January 1, 2018 utilizing the modified retrospective method of adoption.  The adoption resulted in a cumulative effect adjustment of ($685) thousand to the opening balance of retained earnings.  Beginning January 1, 2018, in connection with the adoption of this standard, Synovus began including merchant discounts and other card-related fees in card fees. For periods prior to January 1, 2018, these amounts were previously presented in other non-interest income and have been reclassified for comparability. See "Part I - Item 1. Financial Statements and Supplementary Data - Note 12 - Non-interest Income" for the required disclosures in accordance with this ASU.

ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. In February 2018, the FASB issued final guidance on reclassification of tax effects stranded in other comprehensive income due to Federal Tax Reform. The guidance provides entities the option to reclassify the tax effects that are stranded in accumulated other comprehensive income, or AOCI, as a result of Federal Tax Reform to retained earnings. The guidance is effective for fiscal years beginning after December 15, 2018; early adoption is permitted. Synovus elected to early adopt ASU 2018-02 as of January 1, 2018 and elected to reclassify the income tax effects of Federal Tax Reform from AOCI to retained earnings. For Synovus, tax effects stranded in AOCI due to Federal Tax Reform totaled $7.6 million at December 31, 2017 and primarily related to unrealized losses on the available-for-sale investment securities portfolio. The reclassification adjustment resulted in an increase to retained earnings as of January 1, 2018 of $7.6 million and a corresponding decrease to AOCI for the same amount.

ASU 2016-01, Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. In January 2016, the FASB issued ASU 2016-01 that included targeted amendments to accounting guidance for recognition, measurement, presentation, and disclosure of financial instruments. ASU 2016-01 requires equity investments (except those accounted for under the equity method of accounting or consolidated) to be measured at fair value with changes in fair value recognized in net income. This ASU requires a cumulative-effect adjustment to retained earnings as of the beginning of the reporting period of adoption to reclassify the cumulative change in fair value of equity securities previously recognized in AOCI. ASU 2016-01 became effective for Synovus on January 1, 2018. The adoption of the guidance resulted in a transfer of investments in mutual funds of $3.2 million, at fair value, from investment securities available for sale to other assets and a $117 thousand cumulative-effect adjustment that decreased retained earnings, with offsetting related adjustments to deferred taxes and AOCI. ASU 2016-01 also emphasizes the existing requirement to use an exit price concept to measure fair value for disclosure purposes in determining the fair value of loans. Determination of the fair value under the exit price method requires judgment because substantially all of the loans within the loan portfolio do not have observable market prices. The adoption of this guidance did not have a significant impact on Synovus' fair value disclosures.

Acquisitions

Note 2 - Acquisitions

Cabela's Transaction

On September 25, 2017, Synovus' wholly owned subsidiary, Synovus Bank, completed the acquisition of certain assets and assumption of certain liabilities of World's Foremost Bank, or WFB. Immediately following the closing of this transaction, Synovus Bank sold WFB’s credit card assets and related liabilities to Capital One Bank (USA), National Association, a bank subsidiary of Capital One Financial Corporation.

Synovus retained WFB’s $1.10 billion brokered time deposits portfolio, which had a weighted average remaining maturity of approximately 2.53 years and a weighted average rate of 1.83% as of September 25, 2017. The transaction was accounted for as an assumption of a liability (accounted for under the asset acquisition model). In accordance with ASC 820, Fair Value Measurements and Disclosures, the brokered time deposit portfolio was recorded at $1.10 billion, which was the amount of cash received for the deposits and represented the estimated fair value of the deposits at the transaction date. Additionally, Synovus received a $75.0 million transaction fee from Cabela’s Incorporated and Capital One, which was recognized into earnings on September 25, 2017 upon closing of the transaction, based on having achieved the recognition criteria outlined in SEC SAB Topic 13.A, Revenue Recognition.

Acquisition of Global One

On October 1, 2016, Synovus completed its acquisition of all of the outstanding stock of Global One. Prior to its acquisition, Global One was an Atlanta-based private specialty financial services company that provided financing primarily to commercial entities, with all loans fully collateralized by cash value life insurance policies and/or annuities issued by investment grade life insurance companies. Under the terms of the merger agreement, Synovus acquired Global One for an up-front payment of $30 million, consisting of the issuance of 821 thousand shares of Synovus common stock valued at $26.6 million and $3.4 million in cash, with additional payments to Global One's former shareholders over a three to five year period based on earnings from the Global One business, as further discussed below.

The acquisition of Global One constituted a business combination. Accordingly, the assets acquired and liabilities assumed were recorded at their estimated fair values on October 1, 2016. The determination of fair value required management to make estimates about discount rates, future expected earnings and cash flows, market conditions, future loan growth, and other future events that are highly subjective in nature and subject to change. During the three months ended September 30, 2017, Synovus completed the determination of the final allocation of the purchase price with respect to the assets acquired and liabilities assumed.

Under the terms of the merger agreement, the purchase price includes additional annual payments ("Earnout Payments") to Global One's former shareholders over a three to five year period, with amounts based on a percentage of "Global One Earnings," as defined in the merger agreement. The Earnout Payments consist of shares of Synovus common stock as well as a smaller cash consideration component. The first annual Earnout Payment of stock and cash valued at $6.4 million was made during November 2017. The balance of the earnout liability at June 30, 2018 was $11.3 million based on the estimated fair value of the remaining Earnout Payments.

At June 30, 2018 and December 31, 2017, investment securities with a carrying value of $1.35 billion and $2.00 billion, respectively, were pledged to secure certain deposits and securities sold under repurchase agreements as required by law and contractual agreements.

Synovus has reviewed investment securities that are in an unrealized loss position as of June 30, 2018 and December 31, 2017 for OTTI and does not consider any securities in an unrealized loss position to be other-than-temporarily impaired. If Synovus intended to sell a security in an unrealized loss position, the entire unrealized loss would be reflected in earnings. Synovus does not intend to sell investment securities in an unrealized loss position prior to the recovery of the unrealized loss, which may not be until maturity, and has the ability and intent to hold those securities for that period of time. Additionally, Synovus is not currently aware of any circumstances which will require it to sell any of the securities that are in an unrealized loss position prior to the respective securities' recovery of all such unrealized losses.

Declines in the fair value of available for sale securities below their cost that are deemed to have OTTI are reflected in earnings as realized losses to the extent the impairment is related to credit losses. The amount of the impairment related to other factors is recognized in other comprehensive income. Currently, unrealized losses on debt securities are attributable to increases in interest rates on comparable securities from the date of purchase. Synovus regularly evaluates its investment securities portfolio to ensure that there are no conditions that would indicate that unrealized losses represent OTTI. These factors include the length of time the security has been in a loss position, the extent that the fair value is below amortized cost, and the credit standing of the issuer. As of June 30, 2018, Synovus had 80 investment securities in a loss position for less than twelve months and 55 investment securities in a loss position for twelve months or longer.

Gross unrealized losses on investment securities and the fair value of the related securities, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, at June 30, 2018 and December 31, 2017 are presented below.

The credit quality of the loan portfolio is reviewed and updated no less frequently than quarterly using the standard asset classification system utilized by the federal banking agencies. These classifications are divided into three groups – Not Criticized (Pass), Special Mention, and Classified or Adverse rating (Substandard, Doubtful, and Loss) and are defined as follows:

Pass- loans which are well protected by the current net worth and paying capacity of the obligor (or guarantors, if any) or by the fair value, less cost to acquire and sell in a timely manner, of any underlying collateral.

Special Mention - loans which have potential weaknesses that deserve management's close attention. These loans are not adversely classified and do not expose an institution to sufficient risk to warrant an adverse classification.

Substandard - loans which are inadequately protected by the current net worth and paying capacity of the obligor or by the collateral pledged, if any. Loans with this classification are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected.

Doubtful - loans which have all the weaknesses inherent in loans classified as Substandard with the added characteristic that the weaknesses make collection or liquidation in full highly questionable and improbable on the basis of currently known facts, conditions, and values.

Loss - loans which are considered by management to be uncollectible and of such little value that their continuance on the institution's books as an asset, without establishment of a specific valuation allowance or charge-off, is not warranted.

In the following tables, consumer loans are generally assigned a risk grade similar to the classifications described above; however, upon reaching 90 days and 120 days past due, they are generally downgraded to Substandard and Loss, respectively, in accordance with the FFIEC Uniform Retail Credit Classification and Account Management Policy. Additionally, in accordance with the Interagency Supervisory Guidance on Allowance for Loan and Lease Losses Estimation Practices for Loans and Lines of Credit Secured by Junior Liens on 1-4 Family Residential Properties, the risk grade classifications of home equity lines and consumer mortgages secured by junior liens on 1-4 family residential properties also consider available information on the payment status of any associated senior liens with other financial institutions.

The average recorded investment in impaired loans was $233.8 million and $232.5 million respectively for the six and three months ended June 30, 2017. Excluding accruing TDRs, there was no interest income recognized for the investment in impaired loans for the six and three months ended June 30, 2017. Interest income recognized for accruing TDRs was $3.5 million and $1.8 million respectively for the six and three months ended June 30, 2017. At June 30, 2018 and December 31, 2017, impaired loans of $63.7 million and $49.0 million, respectively, were on non-accrual status.

Concessions provided in a TDR are primarily in the form of providing a below market interest rate given the borrower's credit risk, a period of time generally less than one year with a reduction of required principal and/or interest payments (e.g., interest only for a period of time), or an extension of the maturity of the loan generally for less than one year. Insignificant periods of reduction of principal and/or interest payments, or one-time deferrals of 3 months or less, are generally not considered to be financial concessions.

The following tables represent, by concession type, the post-modification balance for loans modified or renewed during the six and three months ended June 30, 2018 and 2017 that were reported as accruing or non-accruing TDRs.

⁽²⁾ No net charge-offs were recorded during the six and three months ended June 30, 2017 upon restructuring of these loans.

For both the six and three months ended June 30, 2018 there were eight defaults with a recorded investment of $10.5 million on accruing TDRs restructured during the previous twelve months (defaults are defined as the earlier of the TDR being placed on non-accrual status or reaching 90 days past due with respect to principal and/or interest payments) compared to three defaults for both the six and three months ended June 30, 2017 with a recorded investment of $292 thousand.

If, at the time a loan was designated as a TDR, the loan was not already impaired, the measurement of impairment that resulted from the TDR designation closely approximates the reserve derived through specific loan measurement of impairment in accordance with ASC 310-10-35. Generally, the change in the allowance for loan losses resulting from such TDR designation is not significant. At June 30, 2018, the allowance for loan losses allocated to accruing TDRs totaling $125.3 million was $6.5 million compared to accruing TDRs of $151.3 million with an allocated allowance for loan losses of $8.7 million at December 31, 2017. Non-accrual, non-homogeneous loans (commercial-type impaired loans greater than $1 million) that are designated as TDRs are individually measured for the amount of impairment, if any, both before and after the TDR designation.

In accordance with ASC 740-20-45-11(b), a deferred tax asset valuation allowance associated with unrealized gains and losses not recognized in income is charged directly to other comprehensive income (loss). During the years 2010 and 2011, Synovus recorded a deferred tax asset valuation allowance associated with net unrealized losses not recognized in income directly to other comprehensive income (loss) by applying the portfolio approach for allocation of the valuation allowance. Synovus has consistently applied the portfolio approach which treats derivative instruments and available for sale securities as a single portfolio. As of June 30, 2018, the ending balance in net unrealized gains (losses) on cash flow hedges and net unrealized gains (losses) on investment securities available for sale includes unrealized losses of $12.1 million and $13.3 million, respectively, related to the residual tax effects remaining in OCI due to the previously established deferred tax asset valuation allowance. Under the portfolio approach, these unrealized losses are realized at the time the entire portfolio is sold or disposed.

Fair Value Disclosures [Abstract]

Fair Value Accounting

Note 8 - Fair Value Accounting

Synovus carries various assets and liabilities at fair value based on the fair value accounting guidance under ASC 820, Fair Value Measurements, and ASC 825, Financial Instruments. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an “exit price”) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

Fair Value Hierarchy

Synovus determines the fair value of its financial instruments based on the fair value hierarchy established under ASC 820-10, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the financial instrument's fair value measurement in its entirety. There are three levels of inputs that may be used to measure fair value. The three levels of inputs of the valuation hierarchy are defined below:

Level 1	Quoted prices (unadjusted) in active markets for identical assets and liabilities for the instrument or security to be valued. Level 1 assets include U.S. Treasury securities and mutual funds.
Level 2	Observable inputs other than Level 1 quoted prices, such as quoted prices for similar assets and liabilities in active markets, quoted prices in markets that are not active or model-based valuation techniques for which all significant assumptions are derived principally from or corroborated by observable market data. Level 2 assets and liabilities include debt securities with quoted prices that are traded less frequently than exchange-traded instruments and derivative contracts whose value is determined by using a pricing model with inputs that are observable in the market or can be derived principally from or corroborated by observable market data. U.S. Government sponsored agency securities, mortgage-backed securities issued by GSEs and agencies, obligations of states and municipalities, collateralized mortgage obligations issued by GSEs, and mortgage loans held-for-sale are generally included in this category.
Level 3	Unobservable inputs that are supported by little, if any, market activity for the asset or liability. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow models and similar techniques, and may also include the use of market prices of assets or liabilities that are not directly comparable to the subject asset or liability. These methods of valuation may result in a significant portion of the fair value being derived from unobservable assumptions that reflect Synovus' own estimates for assumptions that market participants would use in pricing the asset or liability. This category primarily includes collateral-dependent impaired loans, other loans held for sale, other real estate, certain corporate securities, private equity investments, GGL/SBA loan servicing assets, and the earnout liability.

See "Part II - Item 8. Financial Statements and Supplementary Data - Note 15 - Fair Value Accounting" to the consolidated financial statements of Synovus' 2017 Form 10-K for a description of valuation methodologies for assets and liabilities measured at fair value on a recurring and non-recurring basis.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The following table presents all financial instruments measured at fair value on a recurring basis as of June 30, 2018 and December 31, 2017, according to the valuation hierarchy included in ASC 820-10. For debt securities, class was determined based on the nature and risks of the investments. Synovus did not have any transfers between levels during the six and three months ended June 30, 2018 and year ended December 31, 2017.

⁽¹⁾ Based on an analysis of the nature and risks of these investments, Synovus has determined that presenting these investments as a single asset class is appropriate.

⁽²⁾ Mortgage derivatives consist of customer interest rate lock commitments that relate to the potential origination of mortgage loans, which would be classified as held for sale and forward loan sales commitments with third-party investors.

⁽³⁾ Earnout liability consists of contingent consideration obligation related to the Global One acquisition.

Fair Value Option

The following table summarizes the difference between the fair value and the unpaid principal balance of mortgage loans held for sale measured at fair value and the changes in fair value of these loans. Mortgage loans held for sale are initially measured at fair value with subsequent changes in fair value recognized in earnings. Changes in fair value are recorded as a component of mortgage banking income in the consolidated statements of income. An immaterial portion of these changes in fair value was attributable to changes in instrument-specific credit risk.

Changes in Level 3 Fair Value Measurements and Quantitative Information about Level 3 Fair Value Measurements

As noted above, Synovus uses significant unobservable inputs in determining the fair value of assets and liabilities classified as Level 3 in the fair value hierarchy. The table below includes a roll-forward of the amounts on the consolidated balance sheet for the six and three months ended June 30, 2018 and 2017 (including the change in fair value) for financial instruments of a material nature that are classified by Synovus within Level 3 of the fair value hierarchy and are measured at fair value on a recurring basis. Transfers between fair value levels are recognized at the end of the reporting period in which the associated changes in inputs occur. During the six and three months ended June 30, 2018 and 2017, Synovus did not have any transfers between levels in the fair value hierarchy. For the six and three months ended June 30, 2018, total net losses included in earnings attributable to the change in unrealized losses relating to assets/liabilities still held at June 30, 2018 was $6.2 million and $2.7 million, respectively. For the six and three months ended June 30, 2017, total net losses included in earnings attributable to the change in unrealized losses relating to assets/liabilities still held at June 30, 2017 was $2.4 million and $2.1 million, respectively.

Assets Measured at Fair Value on a Non-recurring Basis

Certain assets are recorded at fair value on a non-recurring basis. These assets are not measured at fair value on an ongoing basis. Non-recurring fair value adjustments typically are a result of the application of lower of cost or fair value accounting or a write-down occurring during the period. For example, if the fair value of an asset in these categories falls below its cost basis, it is considered to be at fair value at the end of the period of the adjustment. The following table presents assets measured at fair value on a non-recurring basis as of the dates indicated for which there was a fair value adjustment during the six months ended June 30, 2018 and year ended December 31, 2017.

The table below provides an overview of the valuation techniques and significant unobservable inputs used in those techniques to measure financial instruments that are classified within Level 3 of the valuation hierarchy and are measured at fair value on a non-recurring basis. The range of sensitivities that management utilized in its fair value calculations is deemed acceptable in the industry with respect to the identified financial instruments.

⁽¹⁾ The range represents management's estimate of the high and low of the value that would be assigned to a particular input. For assets measured at fair value on a non-recurring basis, the weighted average is the measure of central tendencies; it is not the value that management is using for the asset or liability.

⁽²⁾ Synovus also makes adjustments to the values of the assets listed above for reasons including age of the appraisal, information known by management about the property, such as occupancy rates, changes to the physical condition of the property, and other factors.

Fair Value of Financial Instruments

The following table presents the carrying and fair values of financial instruments at June 30, 2018 and December 31, 2017. The fair values represent management’s estimates based on various methodologies and assumptions. For financial instruments that are not recorded at fair value on the balance sheet, such as loans held for investment, interest bearing deposits (including brokered deposits), and long-term debt, the fair value amounts should not be taken as an estimate of the amount that would be realized if all such financial instruments were to be settled immediately.

The carrying and estimated fair values of financial instruments, as well as the level within the fair value hierarchy, as of June 30, 2018 and December 31, 2017 are as follows:

Summary of Derivative Instruments [Abstract]

Derivative Instruments

Note 9 - Derivative Instruments

As part of its overall interest rate risk management activities, Synovus utilizes derivative instruments to manage its exposure to various types of interest rate risk. These derivative instruments generally consist of interest rate swaps, interest rate lock commitments made to prospective mortgage loan customers, and commitments to sell fixed-rate mortgage loans. Interest rate lock commitments represent derivative instruments since it is intended that such loans will be sold.

Synovus may also utilize interest rate swaps to manage interest rate risks primarily arising from its core banking activities. These interest rate swap transactions generally involve the exchange of fixed and floating interest rate payment obligations without the exchange of underlying principal amounts. Swaps may be designated as either cash flow hedges or fair value hedges, as discussed below. As of June 30, 2018 and December 31, 2017, Synovus had no outstanding interest rate swap contracts utilized to manage interest rate risk related to core banking activities.

Synovus is party to master netting arrangements with its dealer counterparties; however, Synovus does not offset assets and liabilities under these arrangements for financial statement presentation purposes.

Counterparty Credit Risk and Collateral

Entering into derivative contracts potentially exposes Synovus to the risk of counterparties’ failure to fulfill their legal obligations, including, but not limited to, potential amounts due or payable under each derivative contract. Notional principal amounts are often used to express the volume of these transactions, but the amounts potentially subject to credit risk are much smaller. Synovus assesses the credit risk of its dealer counterparties by regularly monitoring publicly available credit rating information, evaluating other market indicators, and periodically reviewing detailed financials. Dealer collateral requirements are determined via risk-based policies and procedures and in accordance with existing agreements. Synovus seeks to minimize dealer credit risk by dealing with highly rated counterparties and by obtaining collateral for exposures above certain predetermined limits. Management closely monitors credit conditions within the customer swap portfolio, which management deems to be of higher risk than dealer counterparties. Collateral is secured at origination and credit related fair value adjustments are recorded against the asset value of the derivative as deemed necessary based upon an analysis, which includes consideration of the current asset value of the swap, customer credit rating, collateral value, and customer standing with regards to its swap contractual obligations and other related matters. Such asset values fluctuate based upon changes in interest rates regardless of changes in notional amounts and changes in customer specific risk.

Customer Related Derivative Positions

Synovus enters into interest rate swap agreements to facilitate the risk management strategies of a small number of commercial banking customers. Synovus mitigates this risk by entering into equal and offsetting interest rate swap agreements with highly rated counterparties. The interest rate swap agreements are free-standing derivatives and are recorded at fair value on Synovus' consolidated balance sheet. Fair value changes are recorded as a component of non-interest income. As of June 30, 2018, the notional amount of customer related interest rate derivative financial instruments, including both the customer position and the offsetting position, was $1.67 billion, an increase of $201.4 million compared to December 31, 2017.

Visa Derivative

In conjunction with the sale of Class B shares of common stock issued by Visa to Synovus as a Visa USA member, Synovus entered into a derivative contract with the purchaser, which provides for settlements between the parties based upon a change in the ratio for conversion of Visa Class B shares to Visa Class A shares. The conversion ratio changes when Visa deposits funds to a litigation escrow established by Visa to pay settlements for certain litigation, for which Visa is indemnified by Visa USA members. The litigation escrow is funded by proceeds from Visa’s conversion of Class B shares. The fair value of the derivative contract was $5.9 million and $4.3 million at June 30, 2018 and December 31, 2017, respectively. The fair value of the derivative contract is determined based on management's estimate of the timing and amount of the Covered Litigation settlement, and the resulting payments due to the counterparty under the terms of the contract. During the three months ended June 30, 2018, Synovus recorded a $2.3 million valuation adjustment to the Visa derivative following Visa's announcement on June 26, 2018 that it would deposit $600 million into its litigation escrow account. Management believes that the estimate of Synovus' exposure to the Visa indemnification and fees associated with the Visa derivative is adequate based on current information, including Visa's recent announcements and disclosures. However, future developments in the litigation could require potentially significant changes to Synovus' estimate. See "Part II - Item 8. Financial Statements and Supplementary Data - Note 18 - Visa Shares and Related Agreements" of Synovus' 2017 Form 10-K for further information.

Mortgage Derivatives

Synovus originates first lien residential mortgage loans for sale into the secondary market. Mortgage loans are sold by Synovus for conversion to securities and the servicing of these loans is generally sold to a third-party servicing aggregator, or Synovus sells the mortgage loans as whole loans to investors either individually or in bulk on a servicing released basis.

Synovus enters into interest rate lock commitments for residential mortgage loans which commits it to lend funds to a potential borrower at a specific interest rate and within a specified period of time. Interest rate lock commitments that relate to the origination of mortgage loans that, if originated, will be held for sale, are considered derivative financial instruments under applicable accounting guidance. Outstanding interest rate lock commitments expose Synovus to the risk that the price of the mortgage loans underlying the commitments may decline due to increases in mortgage interest rates from inception of the rate lock to the funding of the loan.

At June 30, 2018 and December 31, 2017, Synovus had commitments to fund at a locked interest rate, primarily fixed-rate mortgage loans to customers in the amount of $69.7 million and $49.3 million, respectively. Fair value adjustments related to these commitments resulted in a gain of $366 thousand and a loss of $(416) thousand for the six months ended June 30, 2018 and 2017, respectively, which was recorded as a component of mortgage banking income in the consolidated statements of income.

At June 30, 2018 and December 31, 2017, outstanding commitments to sell primarily fixed-rate mortgage loans amounted to $86.0 million and $72.5 million, respectively. Such commitments are entered into to reduce the exposure to market risk arising from potential changes in interest rates, which could affect the fair value of mortgage loans held for sale and outstanding rate lock commitments, which guarantee a certain interest rate if the loan is ultimately funded or granted by Synovus as a mortgage loan held for sale. The commitments to sell mortgage loans are at fixed prices and are scheduled to settle at specified dates that generally do not exceed 90 days. Fair value adjustments related to these outstanding commitments to sell mortgage loans resulted in a loss of $(119) thousand and $(1.7) million for the six months ended June 30, 2018 and 2017, respectively, which were recorded as a component of mortgage banking income in the consolidated statements of income.

Collateral Requirements

Pursuant to the Dodd-Frank Act, certain derivative transactions have collateral requirements, both at the inception of the trade and as the value of each derivative position changes. As of June 30, 2018, collateral totaling $30.6 million of federal funds sold was pledged to the derivative counterparties to comply with collateral requirements. Effective January 3, 2017, the CME amended its rulebook to legally characterize variation margin cash payments for cleared OTC derivatives as settlement rather than as collateral. As a result, in 2017, Synovus began reducing the corresponding derivative asset and liability balances for CME-cleared OTC derivatives to reflect the settlement of those positions via the exchange of variation margin. At June 30, 2018 and December 31, 2017, Synovus had a variation margin of $8.9 million and $1.5 million, respectively, reducing the derivative asset.

The impact of derivative instruments on the Consolidated Balance Sheets at June 30, 2018 and December 31, 2017 is presented below.

Note 10 - Net Income Per Common Share

The following table displays a reconciliation of the information used in calculating basic and diluted earnings per common share for the six and three months ended June 30, 2018 and 2017.

Net income per common share, diluted	$	1.75	$	1.16	$	0.91	$	0.60

Basic net income per common share is computed by dividing net income by the average common shares outstanding for the period. Diluted net income per common share reflects the dilution that could occur if securities or other contracts to issue common stock were exercised or converted. The dilutive effect of outstanding stock options and restricted share units is reflected in diluted net income per common share, unless the impact is anti-dilutive, by application of the treasury stock method.

As of June 30, 2018 and 2017, there were 2.2 million potentially dilutive shares related to the Warrant to purchase shares of common stock that were outstanding during 2018 and 2017 but were not included in the computation of diluted net income per common share because the effect would have been anti-dilutive.

Share-based Compensation [Abstract]

Share-based Compensation

Note 11 - Share-based Compensation

General Description of Share-based Plans

Synovus has a long-term incentive plan under which the Compensation Committee of the Board of Directors has the authority to grant share-based awards to Synovus employees. The 2013 Omnibus Plan authorizes 8.6 million common share equivalents available for grant, where grants of options count as one share equivalent and grants of full value awards (e.g., restricted share units, market restricted share units, and performance share units) count as two share equivalents. Any restricted share units that are forfeited and options that expire unexercised will again become available for issuance under the Plan. At June 30, 2018, Synovus had a total of 4.9 million shares of its authorized but unissued common stock reserved for future grants under the 2013 Omnibus Plan. The Plan permits grants of share-based compensation including stock options, restricted share units, market restricted share units, and performance share units. The grants generally include vesting periods ranging from three to five years and contractual terms of ten years. Vesting for grants made in 2018 accelerates upon retirement for plan participants who have reached age 65 and who also have no less than 10 years of service at the date of their election to retire. Market restricted share units and performance share units are granted at a defined target level and are compared annually to required market and performance metrics to determine actual units vested and compensation expense. Synovus has historically issued new shares to satisfy share option exercises and share unit conversions. Dividend equivalents are paid on outstanding restricted share units, market restricted share units, and performance share units in the form of additional restricted share units that vest over the same vesting period or the vesting period left on the original restricted share unit grant.

Share-based Compensation Expense

Total share-based compensation expense was $8.3 million and $4.4 million for the six and three months ended June 30, 2018, respectively, and $6.8 million and $3.5 million for the six and three months ended June 30, 2017, respectively. Accelerated share-based compensation expense associated with the provision in 2018 of a retirement vesting provision was approximately $200 thousand and $30 thousand for the six and three months ended June 30, 2018 for retirement eligible employees.

Stock Options

No stock option grants were made during the six months ended June 30, 2018. At June 30, 2018, there were 655 thousand outstanding stock options to purchase shares of common stock with a weighted average exercise price of $16.92 per share.

Restricted Share Units, Performance Share Units, and Market Restricted Share Units

During the six months ended June 30, 2018, Synovus awarded 234 thousand restricted share units that have a service-based vesting period of three years and awarded 87 thousand performance share units that vest upon service and performance conditions. Synovus also granted 58 thousand market restricted share units during the six months ended June 30, 2018. The weighted average grant-date fair value of the awarded restricted share units, performance share units and market restricted share units was $47.67 per share. Market restricted share units and performance share units are granted at target and are compared annually to required market and performance metrics. The performance share units vest upon meeting certain service and performance conditions. Return on average assets (ROAA) and return on average tangible common equity (ROATCE) performance is evaluated each year over a three-year performance period, with share distribution determined at the end of the three years. The number of performance share units that will ultimately vest ranges from 0% to 150% of target based on Synovus' three-year weighted average ROAA (as defined) and ROATCE (as defined). The market restricted share units have a three-year service-based vesting component as well as a total shareholder return multiplier. The number of market restricted share units that will ultimately vest ranges from 75% to 125% of target based on Synovus' total shareholder return. At June 30, 2018, including dividend equivalents granted, there were 910 thousand restricted share units, performance share units and market restricted share units outstanding with a weighted average grant-date fair value of $40.82 per share.

⁽¹⁾ Other revenues primarily relate to revenues not derived from contracts with customers.

Following is a discussion of key revenues within the scope of the new revenue guidance:

Service Charges on Deposit Accounts: Revenue from service charges on deposit accounts is earned through cash management, wire transfer, and other deposit-related services, as well as overdraft, non-sufficient funds, account management and other deposit-related fees. Revenue is recognized for these services either over time, corresponding with deposit accounts' monthly cycle, or at a point in time for transaction related services and fees. Payment for service charges on deposit accounts is primarily received immediately or in the following month through a direct charge to customers' accounts.

Fiduciary and Asset Management Fees: Fiduciary and asset management fees are primarily comprised of fees earned from the management and administration of trusts and other customer assets. Synovus' performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based upon the month-end market value of the assets under management and the applicable fee rate. Payment is generally received a few days after month-end through a direct charge to customers' accounts. Synovus does not earn performance-based incentives.

Card Fees: Card fees consist primarily of interchange fees from consumer credit and debit cards processed by card association networks, as well as merchant discounts, and other card related services. Interchange rates are generally set by the credit card associations and based on purchase volumes and other factors. Interchange fees and merchant discounts are recognized concurrently with the delivery of service on a daily basis as transactions occur. Payment is typically received immediately or in the following month. Card fees are reported net of certain associated expense items including loyalty program expenses and network expenses.

Brokerage Revenue: Brokerage revenue consists primarily of commissions. Additionally, brokerage revenue includes advisory fees earned from the management of customer assets. Advisory fees for brokerage services are recognized and collected monthly and are based upon the month-end market value of the assets under management at a rate predetermined in the contract. Transactional revenues are based on the size and number of transactions executed at the client's direction and are generally recognized on the trade date with payment received on the settlement date.

Insurance Revenue: Insurance revenue primarily consists of commissions received on annuity and life product sales. The commissions are recognized as revenue when the customer executes an insurance policy with the insurance carrier. In some cases, Synovus receives payment of trailing commissions each year when the customer pays its annual premium. For the six and three months ended June 30, 2018, Synovus recognized an immaterial amount of insurance trailing commissions related to performance obligations satisfied in prior periods.

Other Fees: Other fees primarily consist of revenues generated from safe deposit box rental fees and lockbox services. Fees are recognized over time, on a monthly basis, as Synovus' performance obligation for services is satisfied. Payment is received upfront for safe deposit box rentals and in the following month for lockbox services.

Contract Balances

A contract asset balance occurs when an entity performs a service for a customer before the customer pays consideration (resulting in a contract receivable) or before payment is due (resulting in a contract asset). A contract liability balance is an entity's obligation to transfer a service to a customer for which the entity has already received payment (or payment is due) from the customer. Synovus' non-interest revenue streams are largely based on transactional activity, or standard month-end revenue accruals such as asset management fees based on month-end market values. Consideration is often received immediately or shortly after Synovus satisfies its performance obligation and revenue is recognized. Synovus does not typically enter into long-term revenue contracts with customers, and therefore, does not experience significant contract balances. As of June 30, 2018 and December 31, 2017, Synovus did not have any significant contract balances.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Note 13 - Commitments and Contingencies

In the normal course of business, Synovus enters into commitments to extend credit such as loan commitments and letters of credit to meet the financing needs of its customers. Synovus uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee.

The contractual amount of these financial instruments represents Synovus' maximum credit risk should the counterparty draw upon the commitment, and should the counterparty subsequently fail to perform according to the terms of the contract. Since many of the commitments are expected to expire without being drawn upon, total commitment amounts do not necessarily represent future cash requirements. Additionally, certain commitments (primarily consumer) may generally be canceled by providing notice to the borrower.

The allowance for credit losses associated with unfunded commitments and letters of credit is a component of the unfunded commitments reserve recorded within other liabilities on the consolidated balance sheet. Additionally, unearned fees relating to letters of credit are recorded within other liabilities on the consolidated balance sheet. These amounts are not material to Synovus' consolidated balance sheet.

Unfunded letters of credit and lending commitments at June 30, 2018 and December 31, 2017 are presented below.

(in thousands)	June 30, 2018		December 31, 2017

Merchant Services

In accordance with credit and debit card association rules, Synovus sponsors merchant processing servicers that process credit and debit card transactions on behalf of various merchants. In connection with these services, a liability may arise in the event of a billing dispute between the merchant and a cardholder that is ultimately resolved in the cardholder's favor. If the merchant defaults on its obligation to reimburse the cardholder, the cardholder, through its issuing bank, generally has until six months after the date of the transaction to present a chargeback to the merchant processor, which is primarily liable for any losses on covered transactions. However, if the merchant processor fails to meet its obligation to reimburse the cardholder for disputed transactions, then Synovus, as the sponsor, could be held liable for the disputed amount. Synovus mitigates this risk through its contractual arrangements with the merchant processing servicers and the merchants and by withholding future settlements, by retaining cash reserve accounts or by obtaining other security. During the six months ended June 30, 2018 and 2017, the sponsored entities processed and settled $34.35 billion and $30.42 billion, respectively, in total transactions. For the six months ended June 30, 2018 and 2017, Synovus incurred an immaterial amount of losses in connection with these chargebacks. During July 2018, Synovus began to accrue a receivable for chargebacks associated with one merchant processing relationship.

Legal Proceedings

Synovus and its subsidiaries are subject to various legal proceedings and claims that arise in the ordinary course of its business. Additionally, in the ordinary course of business, Synovus and its subsidiaries are subject to regulatory examinations, information gathering requests, inquiries and investigations. Synovus, like many other financial institutions, has been the target of numerous legal actions and other proceedings asserting claims for damages and related relief for losses. These actions include claims and counterclaims asserted by individual borrowers related to their loans and allegations of violations of state and federal laws and regulations relating to banking practices, including putative class action matters. In addition to actual damages, if Synovus does not prevail in asserted legal actions, credit-related litigation could result in additional write-downs or charge-offs of loans, which could adversely affect Synovus' results of operations during the period in which the write-down or charge-off were to occur.

Synovus carefully examines and considers each legal matter, and, in those situations where Synovus determines that a particular legal matter presents loss contingencies that are both probable and reasonably estimable, Synovus establishes an appropriate accrual. An event is considered to be probable if the future event is likely to occur. While the final outcome of any legal proceeding is inherently uncertain, based on the information currently available, advice of counsel and available insurance coverage, management believes that the amounts accrued with respect to legal matters as of June 30, 2018 are adequate. The actual costs of resolving legal claims may be higher or lower than the amounts accrued.

In addition, where Synovus determines that there is a reasonable possibility of a loss in respect of legal matters, Synovus considers whether it is able to estimate the total reasonably possible loss or range of loss. An event is “reasonably possible” if “the chance of the future event or events occurring is more than remote but less than likely.” An event is “remote” if “the chance of the future event or events occurring is more than slight but less than reasonably possible." In many situations, Synovus may be unable to estimate reasonably possible losses due to the preliminary nature of the legal matters, as well as a variety of other factors and uncertainties. For those legal matters where Synovus is able to estimate a range of reasonably possible losses, management currently estimates the aggregate range from our outstanding litigation is from zero to $5 million in excess of the amounts accrued, if any, related to those matters. This estimated aggregate range is based upon information currently available to Synovus, and the actual losses could prove to be lower or higher. As there are further developments in these legal matters, Synovus will reassess these matters, and the estimated range of reasonably possible losses may change as a result of this assessment. Based on Synovus' current knowledge and advice of counsel, management presently does not believe that the liabilities arising from these legal matters will have a material adverse effect on Synovus' consolidated financial condition, results of operations or cash flows. However, it is possible that the ultimate resolution of these legal matters could have a material adverse effect on Synovus' results of operations for any particular period.

Synovus intends to vigorously pursue all available defenses to these legal matters, but will also consider other alternatives, including settlement, in situations where there is an opportunity to resolve such legal matters on terms that Synovus considers to be favorable, including in light of the continued expense and distraction of defending such legal matters. Synovus maintains insurance coverage, which may be available to cover legal fees, or potential losses that might be incurred in connection with such legal matters. The above-noted estimated range of reasonably possible losses does not take into consideration insurance coverage which may or may not be available for the respective legal matters.

Note 14 - Subsequent Events

Pending Acquisition of FCB Financial Holdings, Inc.

On July 23, 2018, Synovus entered into the Merger Agreement by and among Synovus, FCB and Azalea Merger Sub Corp.  pursuant to which Synovus will acquire FCB in a reverse triangular merger. At the effective time of the Merger, each outstanding share of FCB Class A common stock, par value $0.001 per share, will be converted into the right to receive, without interest, 1.055 shares of Synovus common stock, par value $1.00 per share.  The Merger Agreement has been unanimously approved by both companies’ Board of Directors.  The transaction is subject to customary closing conditions, including approval of Synovus and FCB shareholders and approval of state and federal regulators, and is expected to close by the first quarter of 2019. 

FCB operates 50 full service banking centers through its wholly-owned banking subsidiary, Florida Community Bank.  Following closing, Florida Community Bank will merge with and into Synovus Bank and operate under the Synovus brand.   

Redemption of Series C Preferred Stock

On August 1, 2018, Synovus redeemed all 5,200,000 outstanding shares of Series C Preferred Stock for a cash price of $25.00 per share, without interest, for an aggregate redemption price of $130 million and paid a dividend of $2.6 million on the Series C Preferred Stock. The redemption of the Series C Preferred Stock was funded primarily with proceeds from Synovus' public offering of $200 million of Series D Preferred Stock completed on June 21, 2018. Concurrent with the redemption, Synovus will recognize an extinguishment loss of $4.1 million to net income available to common shareholders. The $4.1 million extinguishment loss will be recognized in a manner similar to the treatment of dividends paid on preferred stock during the three months ending September 30, 2018.

Significant Accounting Policies (Policies)

Jun. 30, 2018

Accounting Policies [Abstract]

Basis of Presentation

The accompanying unaudited interim consolidated financial statements have been prepared in accordance with the instructions to the SEC Form 10-Q and Article 10 of Regulation S-X; therefore, they do not include all information and footnotes necessary for a fair presentation of financial position, results of operations, comprehensive income, and cash flows in conformity with GAAP. All adjustments consisting of normally recurring accruals that, in the opinion of management, are necessary for a fair presentation of the consolidated financial position and results of operations for the periods covered by this Report have been included. The accompanying unaudited interim consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes appearing in Synovus' 2017 Form 10-K.

In connection with the adoption of ASU 2016-18, Statement of Cash Flows-Restricted Cash, Synovus changed its presentation of cash and cash equivalents, effective January 1, 2018, to include cash and due from banks as well as interest bearing funds with the Federal Reserve Bank, interest earning deposits with banks, and federal funds sold and securities purchased under resale agreements, which are inclusive of any restricted cash and restricted cash equivalents. Prior to 2018, cash and cash equivalents only included cash and due from banks. Prior periods have been revised to maintain comparability. Excluding the aforementioned presentation change, there have been no significant changes to the accounting policies as disclosed in Synovus' 2017 Form 10-K.

In preparing the unaudited interim consolidated financial statements in accordance with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the respective consolidated balance sheets and the reported amounts of revenues and expenses for the periods presented. Actual results could differ significantly from those estimates.

Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses, the fair value of investment securities, and the fair value of private equity investments.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash and due from banks, interest bearing funds with the Federal Reserve Bank, interest earning deposits with banks, federal funds sold and securities purchased under resale agreements, and is inclusive of any restricted cash and restricted cash equivalents. Restricted cash and restricted cash equivalents primarily relate to cash held on deposit with the Federal Reserve to meet reserve requirements as well as cash posted as collateral for derivatives in a liability position. At June 30, 2018 and December 31, 2017, interest bearing funds with the Federal Reserve Bank included $35.7 million and $8.6 million, respectively, on deposit to meet Federal Reserve Bank requirements. Interest earning deposits with banks include $2.7 million and $5.9 million at June 30, 2018 and December 31, 2017, respectively, which are pledged as collateral in connection with certain letters of credit. Federal funds sold include $30.6 million and $43.8 million at June 30, 2018 and December 31, 2017, respectively, which are pledged to collateralize certain derivative financial instruments. Federal funds sold and securities purchased under resale agreements generally mature in one day.

Income Taxes

On December 22, 2017, Federal Tax Reform was enacted into law. The new legislation included a decrease in the corporate federal income tax rate from 35% to 21% effective January 1, 2018. Under ASC 740, the effects of the changes in tax rates and laws are recognized in the period in which the new legislation is enacted. Therefore, Synovus was required to remeasure its deferred tax assets and liabilities and record the adjustment to income tax expense effective December 22, 2017. In December 2017, the SEC issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (SAB 118), which allowed companies to record provisional amounts during a measurement period not to extend beyond one year of the enactment date. Since Federal Tax Reform was enacted late in 2017, management expects that certain deferred tax assets and liabilities will continue to be evaluated in the context of Federal Tax Reform through the date of the filing of our 2017 federal income tax return, and may change as a result of evolving management interpretations, elections, and assumptions, as well as new guidance that may be issued by the Internal Revenue Service.   Accordingly, the federal income tax expense of $47.2 million recorded in 2017 relating to the effects from Federal Tax Reform is considered provisional. Management expects to complete its analysis within the measurement period in accordance with SAB 118.  

Recently Adopted Accounting Standards Updates

ASU 2014-09, Revenue from Contracts with Customers (Topic 606) issued by the FASB in May 2014, and all subsequent ASUs that modified 606. ASU 2014-09 implements a common revenue standard that establishes principles for reporting information about the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts to provide goods or services to customers. The core principle of the revenue model is that a company will recognize revenue when it transfers control of goods or services to customers at an amount that reflects the consideration to which it expects to be entitled in exchange for those goods or services. The scope of the guidance explicitly excludes net interest income as well as many other revenues from financial assets. Management reviewed its revenue streams and contracts with customers and did not identify material changes to the timing or amount of revenue recognition. Synovus adopted these ASUs on the required effective date of January 1, 2018 utilizing the modified retrospective method of adoption.  The adoption resulted in a cumulative effect adjustment of ($685) thousand to the opening balance of retained earnings.  Beginning January 1, 2018, in connection with the adoption of this standard, Synovus began including merchant discounts and other card-related fees in card fees. For periods prior to January 1, 2018, these amounts were previously presented in other non-interest income and have been reclassified for comparability. See "Part I - Item 1. Financial Statements and Supplementary Data - Note 12 - Non-interest Income" for the required disclosures in accordance with this ASU.

ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. In February 2018, the FASB issued final guidance on reclassification of tax effects stranded in other comprehensive income due to Federal Tax Reform. The guidance provides entities the option to reclassify the tax effects that are stranded in accumulated other comprehensive income, or AOCI, as a result of Federal Tax Reform to retained earnings. The guidance is effective for fiscal years beginning after December 15, 2018; early adoption is permitted. Synovus elected to early adopt ASU 2018-02 as of January 1, 2018 and elected to reclassify the income tax effects of Federal Tax Reform from AOCI to retained earnings. For Synovus, tax effects stranded in AOCI due to Federal Tax Reform totaled $7.6 million at December 31, 2017 and primarily related to unrealized losses on the available-for-sale investment securities portfolio. The reclassification adjustment resulted in an increase to retained earnings as of January 1, 2018 of $7.6 million and a corresponding decrease to AOCI for the same amount.

ASU 2016-01, Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. In January 2016, the FASB issued ASU 2016-01 that included targeted amendments to accounting guidance for recognition, measurement, presentation, and disclosure of financial instruments. ASU 2016-01 requires equity investments (except those accounted for under the equity method of accounting or consolidated) to be measured at fair value with changes in fair value recognized in net income. This ASU requires a cumulative-effect adjustment to retained earnings as of the beginning of the reporting period of adoption to reclassify the cumulative change in fair value of equity securities previously recognized in AOCI. ASU 2016-01 became effective for Synovus on January 1, 2018. The adoption of the guidance resulted in a transfer of investments in mutual funds of $3.2 million, at fair value, from investment securities available for sale to other assets and a $117 thousand cumulative-effect adjustment that decreased retained earnings, with offsetting related adjustments to deferred taxes and AOCI. ASU 2016-01 also emphasizes the existing requirement to use an exit price concept to measure fair value for disclosure purposes in determining the fair value of loans. Determination of the fair value under the exit price method requires judgment because substantially all of the loans within the loan portfolio do not have observable market prices. The adoption of this guidance did not have a significant impact on Synovus' fair value disclosures.

Reclassifications

Prior periods' consolidated financial statements are reclassified whenever necessary to conform to the current periods' presentation.

Revenue from Contracts with Customers

Following is a discussion of key revenues within the scope of the new revenue guidance:

Service Charges on Deposit Accounts: Revenue from service charges on deposit accounts is earned through cash management, wire transfer, and other deposit-related services, as well as overdraft, non-sufficient funds, account management and other deposit-related fees. Revenue is recognized for these services either over time, corresponding with deposit accounts' monthly cycle, or at a point in time for transaction related services and fees. Payment for service charges on deposit accounts is primarily received immediately or in the following month through a direct charge to customers' accounts.

Fiduciary and Asset Management Fees: Fiduciary and asset management fees are primarily comprised of fees earned from the management and administration of trusts and other customer assets. Synovus' performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based upon the month-end market value of the assets under management and the applicable fee rate. Payment is generally received a few days after month-end through a direct charge to customers' accounts. Synovus does not earn performance-based incentives.

Card Fees: Card fees consist primarily of interchange fees from consumer credit and debit cards processed by card association networks, as well as merchant discounts, and other card related services. Interchange rates are generally set by the credit card associations and based on purchase volumes and other factors. Interchange fees and merchant discounts are recognized concurrently with the delivery of service on a daily basis as transactions occur. Payment is typically received immediately or in the following month. Card fees are reported net of certain associated expense items including loyalty program expenses and network expenses.

Brokerage Revenue: Brokerage revenue consists primarily of commissions. Additionally, brokerage revenue includes advisory fees earned from the management of customer assets. Advisory fees for brokerage services are recognized and collected monthly and are based upon the month-end market value of the assets under management at a rate predetermined in the contract. Transactional revenues are based on the size and number of transactions executed at the client's direction and are generally recognized on the trade date with payment received on the settlement date.

Insurance Revenue: Insurance revenue primarily consists of commissions received on annuity and life product sales. The commissions are recognized as revenue when the customer executes an insurance policy with the insurance carrier. In some cases, Synovus receives payment of trailing commissions each year when the customer pays its annual premium. For the six and three months ended June 30, 2018, Synovus recognized an immaterial amount of insurance trailing commissions related to performance obligations satisfied in prior periods.

Other Fees: Other fees primarily consist of revenues generated from safe deposit box rental fees and lockbox services. Fees are recognized over time, on a monthly basis, as Synovus' performance obligation for services is satisfied. Payment is received upfront for safe deposit box rentals and in the following month for lockbox services.

Contract Balances

A contract asset balance occurs when an entity performs a service for a customer before the customer pays consideration (resulting in a contract receivable) or before payment is due (resulting in a contract asset). A contract liability balance is an entity's obligation to transfer a service to a customer for which the entity has already received payment (or payment is due) from the customer. Synovus' non-interest revenue streams are largely based on transactional activity, or standard month-end revenue accruals such as asset management fees based on month-end market values. Consideration is often received immediately or shortly after Synovus satisfies its performance obligation and revenue is recognized. Synovus does not typically enter into long-term revenue contracts with customers, and therefore, does not experience significant contract balances. As of June 30, 2018 and December 31, 2017, Synovus did not have any significant contract balances.

⁽¹⁾ Based on an analysis of the nature and risks of these investments, Synovus has determined that presenting these investments as a single asset class is appropriate.

⁽²⁾ Mortgage derivatives consist of customer interest rate lock commitments that relate to the potential origination of mortgage loans, which would be classified as held for sale and forward loan sales commitments with third-party investors.

⁽³⁾ Earnout liability consists of contingent consideration obligation related to the Global One acquisition.

Changes in Fair Value Included in Consolidated Statements of Income

The following table summarizes the difference between the fair value and the unpaid principal balance of mortgage loans held for sale measured at fair value and the changes in fair value of these loans. Mortgage loans held for sale are initially measured at fair value with subsequent changes in fair value recognized in earnings. Changes in fair value are recorded as a component of mortgage banking income in the consolidated statements of income. An immaterial portion of these changes in fair value was attributable to changes in instrument-specific credit risk.

Changes in Level 3 Fair Value Measurements

The table below includes a roll-forward of the amounts on the consolidated balance sheet for the six and three months ended June 30, 2018 and 2017 (including the change in fair value) for financial instruments of a material nature that are classified by Synovus within Level 3 of the fair value hierarchy and are measured at fair value on a recurring basis. Transfers between fair value levels are recognized at the end of the reporting period in which the associated changes in inputs occur. During the six and three months ended June 30, 2018 and 2017, Synovus did not have any transfers between levels in the fair value hierarchy. For the six and three months ended June 30, 2018, total net losses included in earnings attributable to the change in unrealized losses relating to assets/liabilities still held at June 30, 2018 was $6.2 million and $2.7 million, respectively. For the six and three months ended June 30, 2017, total net losses included in earnings attributable to the change in unrealized losses relating to assets/liabilities still held at June 30, 2017 was $2.4 million and $2.1 million, respectively.

⁽²⁾Effective January 1, 2017, Synovus elected the fair value option for determining the value of the GGL/SBA loans servicing asset. Prior to 2017, Synovus accounted for the GGL/SBA loans servicing asset using the amortization method.

Fair Value Inputs, Assets, Quantitative Information

The table below provides an overview of the valuation techniques and significant unobservable inputs used in those techniques to measure financial instruments that are classified within Level 3 of the valuation hierarchy and are measured at fair value on a non-recurring basis. The range of sensitivities that management utilized in its fair value calculations is deemed acceptable in the industry with respect to the identified financial instruments.

			June 30, 2018	December 31, 2017
	Valuation Technique	Significant Unobservable Input	Range (Weighted Average)(1)	Range (Weighted Average)(1)
Assets measured at fair value on a non-recurring basis
Collateral dependent impaired loans	Third-party appraised value of collateral less estimated selling costs	Discount to appraised value (2) Estimated selling costs	0% - 68% (38%) 0% - 10% (7%)	0%-50% (15%) 0%-10% (7%)
Other loans held for sale	Third-party appraised value of collateral less estimated selling costs	Discount to appraised value (2) Estimated selling costs	N/A N/A	5% - 99% (54%) 0% - 10% (2%)
Other real estate	Third-party appraised value of real estate less estimated selling costs	Discount to appraised value (2) Estimated selling costs	N/A N/A	0%-85% (35%) 0%-10% (7%)
Other assets held for sale	Third-party appraised value less estimated selling costs or BOV	Discount to appraised value (2) Estimated selling costs	27%-43% (42%) 0%-10% (7%)	21%-52% (25%) 0%-10% (7%)

⁽¹⁾ The range represents management's estimate of the high and low of the value that would be assigned to a particular input. For assets measured at fair value on a non-recurring basis, the weighted average is the measure of central tendencies; it is not the value that management is using for the asset or liability.

⁽²⁾ Synovus also makes adjustments to the values of the assets listed above for reasons including age of the appraisal, information known by management about the property, such as occupancy rates, changes to the physical condition of the property, and other factors.

The table below provides an overview of the valuation techniques and significant unobservable inputs used in those techniques to measure financial instruments that are classified within Level 3 of the valuation hierarchy and are measured at fair value on a recurring basis.
