This model calculates an expected life-of-loan loss percentage for each loan category by considering the forecasted PD, which is the probability that a borrower will default, adjusted for relevant forecasted macroeconomic factors comprising multiple weighted scenarios representing different plausible outcomes, and LGD, which is the estimate of the amount of net loss in the event of default.</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-align:justify;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Expected credit losses are estimated over the contractual term of the loan, adjusted for expected prepayments and curtailments when appropriate. Management's determination of the contract term excludes expected extensions, renewals, and modifications unless either of the following applies: there is a reasonable expectation at the reporting date that a TDR will be executed with an individual borrower, or an extension or renewal option is included in the contract at the reporting date that is not unconditionally cancellable by Synovus.</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-align:justify;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">To the extent the lives of the loans in the portfolio extend beyond the period for which a reasonable and supportable forecast can be made (which is two years for Synovus), the Company reverts, on a straight-line basis back to the historical rates over a one year period.</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-align:justify;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Life-of-loan loss percentages may also be adjusted, as necessary, for certain quantitative and qualitative factors that in management's judgment are necessary to reflect losses expected in the portfolio. These adjustments address inherent limitations in the quantitative model including uncertainty and limitations, among others.</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-align:justify;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The above reflects the ALL estimation process for most commercial and consumer sub-pools. In some cases, Synovus may apply other acceptable loss rate models to smaller sub-pools.</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-align:justify;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Loans that do not share risk characteristics are individually evaluated on a loan-by-loan basis with specific reserves, if any, recorded as appropriate. Specific reserves are determined based on two methods: discounted cash flow based upon the loan's contractual effective interest rate or at the fair value of the collateral, less costs to sell if the loan is collateral-dependent.</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-align:justify;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">For individually evaluated loans, under the DCF method, resulting expected credit losses are recorded as a specific reserve with a charge-off for any portion of the expected credit loss that is determined not to be recoverable. The reserve is reassessed each quarter and adjusted as appropriate based on changes in estimated cash flows. Additionally, where guarantors are determined to be a source of repayment, an assessment of the guarantee is required. This guarantee assessment would include, but not be limited to, factors such as type and feature of the guarantee, consideration for the guarantor's financial strength and capacity to service the loan in combination with the guarantor's other financial obligations as well as the guarantor's willingness to assist in servicing the loan.</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-align:justify;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">For individually evaluated loans, if the loan is collateral-dependent, then the fair value of the loan's collateral, less estimated selling costs, is compared to the loan's carrying amount to determine impairment. Fair value is estimated using appraisals performed by a certified or licensed appraiser. Management also considers other factors or recent developments, such as changes in absorption rates or market conditions at the time of valuation, selling costs and anticipated sales values, taking into account management's plans for disposition, which could result in adjustments to the fair value estimates indicated in the appraisals. The assumptions used in determining the amount of the impairment are subject to significant judgment. Use of different assumptions, for example, changes in the fair value of the collateral or management's plans for disposition could have a significant impact on the amount of impairment.</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Purchased Loans with Credit Deterioration</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-align:justify;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Purchased loans are evaluated upon acquisition in order to determine if the loan, or pool of loans, has experienced more-than-insignificant deterioration in credit quality since origination or issuance. In the performance of this evaluation, Synovus considers migration of the credit quality of the loans at origination in comparison to the credit quality at acquisition.</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-align:justify;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Purchased loans classified as PCD are recognized in accordance with ASC 326-20-30, whereby the amortized cost basis of the PCD asset is ‘grossed-up’ by the initial estimate of credit losses with an offset to the ALL.

This allowance is included in other liabilities on the consolidated balance sheets with associated expense recognized as a component of the provision for credit losses on the consolidated statements of income. The reserve for off-balance-sheet credit exposures considers the likelihood that funding will occur and estimates the expected credit losses on resulting commitments expected to be funded over their estimated life using the estimated loss rates on loans held for investment.</span></div><div style="margin-bottom:6pt;margin-top:6pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Commercial Loans - Risk Ratings </span></div><div style="margin-bottom:6pt;margin-top:6pt;text-align:justify;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Synovus utilizes two primary methods for risk assessment of the commercial loan portfolio: SRR Assessment and DRR Assessment. DRR is a statistical model approach to risk rating that includes a PD and a LGD. The SRR model is an expert judgment based model that results in a blended (i.e. single) rating. The single and dual risk ratings are based on the borrowers' </span></div><div style="margin-bottom:6pt;margin-top:6pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">credit risk profile, considering factors such as debt service history, current and estimated prospective cash flow information, collateral supporting the credit, source of repayment as well as other variables, as appropriate.</span></div><div style="margin-bottom:6pt;margin-top:6pt;text-align:justify;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Each loan is assigned a risk rating during its initial approval process. Commercial loans include classifications of pass, special mention, substandard, doubtful, and loss consistent with bank regulatory classifications. </span></div><div style="margin-bottom:6pt;margin-top:6pt;text-align:justify;text-indent:18pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The loan rating (for both SRR and DRR loans) is subject to approvals from other members of management, regional credit and/or loan committees depending on the size of the loan and credit attributes. Loan ratings are regularly re-evaluated based upon annual scheduled credit reviews or on a more frequent basis if determined prudent by management. Additionally, an independent loan review function evaluates Synovus' risk rating processes on a continuous basis. The primary determinants of the risk ratings for commercial loans are the reliability of the primary source of repayment and the borrower's expected performance. Expected performance is based upon a full analysis of the borrower's historical financial results, current financial strength and future prospects, which includes any external drivers. </span></div><div style="margin-bottom:6pt;margin-top:6pt;text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Consumer Loans – Risk Ratings </span></div>Consumer loans 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. Consumer loans are generally assigned a risk rating based on credit bureau scores. At 90 days past due, a loan grade substandard non-accrual is applied and at 120 days past due, the loan is generally charged-off. The consumer loan portfolio is sent on a quarterly basis to a consumer credit reporting agency for a refresh of clients' credit scores so that management can evaluate ongoing consistency or negative migration in the quality of the portfolio. Revolving lines of credit are reviewed for a material change in financial circumstances and, when appropriate, the line of credit may be suspended for further advances.
