CHFC 2018 Annual Report

Condition and Results of Operations and "Market Risk" in Item 7A. Quantitative and Qualitative Disclosures About Market Risk, located elsewhere in this Annual Report, for further discussion related to our management of interest rate risk. We may be required to pay additional deposit insurance premiums to the FDIC, which could negatively impact earnings. The FDIC insures deposits at FDIC-insured depository institutions, such as Chemical Bank, up to $250,000 per account. The amount of a particular institution’s deposit insurance assessment is based on that institution’s risk classification under an FDIC risk-based assessment system. Depending upon the magnitude of future losses that the FDIC deposit insurance fund suffers, there can be no assurance that there will not be additional premium increases or assessments in order to replenish the fund. The FDIC may need to set a higher base rate schedule based on future financial institution failures and updated failure and loss projections. Potentially higher FDIC assessment rates than those currently projected or special assessments could have an adverse impact on our financial condition and results of operations. Our evaluation of investment securities for other-than-temporary impairment involves subjective determinations and could materially impact our financial condition and results of operations. Our evaluation of impairments in our investment securities portfolio involves a quantitative and qualitative process, which is subject to risks and uncertainties and is intended to determine whether declines in the fair value of such investments should be recognized in current period earnings. The risks and uncertainties include changes in general economic conditions, the issuer's net income, projected net income and financial condition or future recovery prospects, the effects of changes in interest rates or credit spreads and the expected recovery period. Estimating future cash flows involves incorporating information received from third- party sources and making internal assumptions and judgments regarding the future performance of the underlying collateral and/ or value of the underlying asset and also assessing the probability that an adverse change in future cash flows has occurred. The determination of the amount of other-than-temporary impairments is based upon our quarterly evaluation and assessment of known and inherent risks associated with the respective asset class. Such evaluations and assessments are revised as conditions change and new information becomes available. Additionally, our management considers a wide range of factors about the security issuer and uses judgment in evaluating the cause of the decline in the estimated fair value of the security and in assessing the prospects for recovery. Inherent in management's evaluation of the security are assumptions and estimates about the operations of the issuer and its future earnings potential. Considerations in the impairment evaluation process include, but are not limited to: (i) the length of time and the extent to which the market value has been less than cost or amortized cost; (ii) the potential for impairments of securities when the issuer is experiencing significant financial difficulties; (iii) the potential for impairments in an entire industry sector or sub-sector; (iv) the potential for impairments in certain economically depressed geographic locations; (v) the potential for impairments of securities where the issuer, series of issuers or industry has suffered a catastrophic type of loss or has exhausted natural resources; (vi) our intent and ability to retain the investment for a period of time sufficient to allow for the recovery of its value; (vii) unfavorable changes in forecasted cash flows on residential mortgage-backed and asset-backed securities; and (viii) other subjective factors, including concentrations and information obtained from regulators and rating agencies. Impairments to the carrying value of our investment securities may need to be taken in the future, which could have a material adverse effect on our financial condition and results of operations. We may be required to recognize an impairment of our goodwill or core deposit intangible assets, or to establish a valuation allowance against our deferred income tax assets, which could have a material adverse effect on our financial condition and results of operations. Goodwill represents the excess of the amounts paid to acquire subsidiaries over the fair value of their net assets at the date of acquisition. We test goodwill at least annually for impairment. Substantially all of our goodwill at December 31, 2018 was recorded on the books of Chemical Bank. The fair value of Chemical Bank is impacted by the performance of its business and other factors. Core deposit intangible ("CDI") assets represent the estimated value of stable customer deposits, excluding time deposits, acquired in business combinations that provide a source of funds belowmarket interest rates. We amortize our CDI assets over the estimated period the corresponding customer deposits are expected to exist. We test our CDI assets periodically for impairment. If we experience higher than expected deposit run-off, our CDI assets could be impaired. If we determined that our goodwill or CDI assets have been impaired, we must recognize a write-down by the amount of the impairment, with a corresponding charge to net income. Such write-downs could have a material adverse effect on our financial condition and results of operations. At December 31, 2018, we had $1.13 billion of goodwill, representing 40.0% of shareholders' equity. We had $28.6 million of CDI assets at December 31, 2018. Deferred income tax represents the tax effect of the differences between the book and tax basis of assets and liabilities. Deferred tax assets are assessed periodically by management to determine if they are realizable. Factors in management's 24
