COMPONENTS OF THE LOAN PORTFOLIO The loan portfolio is disaggregated into segments and then further disaggregated into classes for certain disclosures. GAAP defines a portfolio segment as the level at which an entity develops and documents a systematic method for determining its allowance for credit losses. A class is generally determined based on the initial measurement attribute (i.e., amortized cost or purchased credit-impaired), risk characteristics of the loan, and FHN’s method for monitoring and assessing credit risk. Commercial loan portfolio segments include commercial, financial and industrial (“C&I”) and commercial real estate ("CRE"). Commercial classes within C&I include general C&I, loans to mortgage companies, the trust preferred loans (“TRUPS”) (i.e. long-term unsecured loans to bank and insurance-related businesses) portfolio and purchased credit-impaired (“PCI”) loans. Loans to mortgage companies include commercial lines of credit to qualified mortgage companies primarily for the temporary warehousing of eligible mortgage loans prior to the borrower’s sale of those mortgage loans to third party investors. Commercial classes within CRE include income CRE, residential CRE and PCI loans. Consumer loan portfolio segments include consumer real estate, permanent mortgage, and the credit card and other portfolio. Consumer classes include home equity lines of credit (“HELOCs”), real estate (“R/E”) installment and PCI loans within the consumer real estate segment, permanent mortgage (which is both a segment and a class), and credit card and other. Concentrations FHN has a concentration of residential real estate loans (24 percent of total loans), the majority of which is in the consumer real estate segment (23 percent of total loans). Loans to finance and insurance companies total $2.9 billion (18 percent of the C&I portfolio, or 10 percent of the total loans). FHN had loans to mortgage companies totaling $2.1 billion (13 percent of the C&I segment, or 8 percent of total loans) as of December 31, 2017. As a result, 31 percent of the C&I segment is sensitive to impacts on the financial services industry. Restrictions On December 31, 2017, $4.6 billion of commercial loans were pledged to secure potential discount window borrowings from the Federal Reserve Bank. Additionally, as of December 31, 2017 and 2016, FHN pledged all of its first and second lien mortgages and HELOCs, excluding restricted real estate loans to secure potential borrowings from the FHLB-Cincinnati. Restricted loans secure borrowings associated with consolidated VIEs. See Note 21 - Variable Interest Entities for additional discussion. Acquisition On November 30, 2017, FHN completed its acquisition of CBF. The acquisition included $7.6 billion in unpaid balance of loans with a fair value of $7.4 billion of which $132.8 million is held-for-sale. Generally, the fair value for the acquired loans is estimated using a discounted cash flow analysis with significant unobservable inputs (Level 3) including adjustments for expected credit losses, prepayment speeds, current market rates for similar loans, and an adjustment for investor-required yield given product-type and various risk characteristics. At acquisition, FHN designated certain loans as PCI with the remaining loans accounted for under ASC 310-20, “Nonrefundable Fees and Other Costs”. Of the loans designated as PCI at acquisition, $5.0 million is held-for-sale. For loans accounted for under ASC 310-20, the difference between each loan’s book value and the estimated fair value at the time of the acquisition will be accreted into interest income over its remaining contractual life and the subsequent accounting and reporting will be similar to a loan in FHN’s originated portfolio. The following tables reflect FHN's contractually required payments receivable, cash flows expected to be collected and the fair value of the acquired loans at the acquisition date of November 30, 2017. These amounts are considered provisional as management continues to identify and assess information regarding the nature of these assets and reviews the associated valuation assumptions and methodologies.

Asset Quality Indicators FHN employs a dual grade commercial risk grading methodology to assign an estimate for the probability of default (“PD”) and the loss given default (“LGD”) for each commercial loan using factors specific to various industry, portfolio, or product segments that result in a rank ordering of risk and the assignment of grades PD 1 to PD 16. This credit grading system is intended to identify and measure the credit quality of the loan portfolio by analyzing the migration of loans between grading categories. It is also integral to the estimation methodology utilized in determining the allowance for loan losses since an allowance is established for pools of commercial loans based on the credit grade assigned. Each PD grade corresponds to an estimated one-year default probability percentage; a PD 1 has the lowest expected default probability, and probabilities increase as grades progress down the scale. PD 1 through PD 12 are “pass” grades. PD grades 13-16 correspond to the regulatory-defined categories of special mention (13), substandard (14), doubtful (15), and loss (16). Pass loan grades are required to be reassessed annually or earlier whenever there has been a material change in the financial condition of the borrower or risk characteristics of the relationship. All commercial loans over $1 million and certain commercial loans over $500,000 that are graded 13 or worse are reassessed on a quarterly basis. Loan grading discipline is regularly reviewed internally by Credit Assurance Services to determine if the process continues to result in accurate loan grading across the portfolio. FHN may utilize availability of guarantors/sponsors to support lending decisions during the credit underwriting process and when determining the assignment of internal loan grades. LGD grades are assigned based on a scale of 1-12 and represent FHN’s expected recovery based on collateral type in the event a loan defaults. See Note 5 – Allowance for Loan Losses for further discussion on the credit grading system. The following tables provide the balances of commercial loan portfolio classes with associated allowance, disaggregated by PD grade as of December 31, 2017 and 2016:

The consumer portfolio is comprised primarily of smaller-balance loans which are very similar in nature in that most are standard products and are backed by residential real estate. Because of the similarities of consumer loan-types, FHN is able to utilize the Fair Isaac Corporation (“FICO”) score, among other attributes, to assess the credit quality of consumer borrowers. FICO scores are refreshed on a quarterly basis in an attempt to reflect the recent risk profile of the borrowers. Accruing delinquency amounts are indicators of asset quality within the credit card and other consumer portfolio. The following table reflects the percentage of balances outstanding by average, refreshed FICO scores for the HELOC, real estate installment, and permanent mortgage classes of loans as of December 31, 2017 and 2016:
|  | December 31, 2017 |  | December 31, 2016

(a) TRUPS is presented net of the valuation allowance of $25.5 million. Troubled Debt Restructurings As part of FHN’s ongoing risk management practices, FHN attempts to work with borrowers when necessary to extend or modify loan terms to better align with their current ability to repay. Extensions and modifications to loans are made in accordance with internal policies and guidelines which conform to regulatory guidance. Each occurrence is unique to the borrower and is evaluated separately. A modification is classified as a TDR if the borrower is experiencing financial difficulty and it is determined that FHN has granted a concession to the borrower. FHN may determine that a borrower is experiencing financial difficulty if the borrower is currently in default on any of its debt, or if it is probable that a borrower may default in the foreseeable future. Many aspects of a borrower’s financial situation are assessed when determining whether they are experiencing financial difficulty. Concessions could include extension of the maturity date, reductions of the interest rate (which may make the rate lower than current market for a new loan with similar risk), reduction or forgiveness of accrued interest, or principal forgiveness. The assessments of whether a borrower is experiencing (or is likely to experience) financial difficulty, and whether a concession has been granted, are subjective in nature and management’s judgment is required when determining whether a modification is classified as a TDR. For all classes within the commercial portfolio segment, TDRs are typically modified through forbearance agreements (generally 6 to 12 months). Forbearance agreements could include reduced interest rates, reduced payments, release of guarantor, or entering into short sale agreements. FHN’s proprietary modification programs for consumer loans are generally structured using parameters of U.S. government-sponsored programs such as the former Home Affordable Modification Program (“HAMP”). Within the HELOC and R/E installment loans classes of the consumer portfolio segment, TDRs are typically modified by reducing the interest rate (in increments of 25 basis points to a minimum of 1 percent for up to 5 years) and a possible maturity date extension to reach an affordable housing debt-to-income ratio. After 5 years, the interest rate generally returns to the original interest rate prior to modification; for certain modifications, the modified interest rate increases 2 percent per year until the original interest rate prior to modification is achieved. Permanent mortgage TDRs are typically modified by reducing the interest rate (in increments of 25 basis points to a minimum of 2 percent for up to 5 years) and a possible maturity date extension to reach an affordable housing debt-to-income ratio. After 5 years, the interest rate steps up 1 percent every year until it reaches the Federal Home Loan Mortgage Corporation Weekly Survey Rate cap. Contractual maturities may be extended to 40 years on permanent mortgages and to 30 years for consumer real estate loans. Within the credit card class of the consumer portfolio segment, TDRs are typically modified through either a short-term credit card hardship program or a longer-term credit card workout program. In the credit card hardship program, borrowers may be granted rate and payment reductions for 6 months to 1 year. In the credit card workout program, customers are granted a rate reduction to 0 percent and term extensions for up to 5 years to pay off the remaining balance. Despite the absence of a loan modification, the discharge of personal liability through bankruptcy proceedings is considered a concession. As a result, FHN classifies all non-reaffirmed residential real estate loans discharged in Chapter 7 bankruptcy as nonaccruing TDRs. On December 31, 2017 and 2016, FHN had $234.4 million and $285.2 million of portfolio loans classified as TDRs, respectively. For TDRs in the loan portfolio, FHN had loan loss reserves of $37.3 million, or 16 percent as of December 31, 2017, and $44.9 million, or 16 percent as of December 31, 2016. Additionally, $63.2 million and $69.3 million of loans held-for-sale as of December 31, 2017 and 2016, respectively, were classified as TDRs. The following tables reflect portfolio loans that were classified as TDRs during the year ended December 31, 2017 and 2016:
