⁽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 three months ended March 31, 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 three months ended March 31, 2018 and 2017, Synovus did not have any transfers between levels in the fair value hierarchy.

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.
