Loan balances are presented net of unearned income and fees, which amounted to $144.1 million at September 30, 2015 and $144.7 million at December 31, 2014.
Owner occupied and commercial real estate (“CRE”) loans include unamortized premiums of approximately $28.8 million at September 30, 2015 and $36.5 million at December 31, 2014.
Municipal loans generally include loans to municipalities with the debt service being repaid from general funds or pledged revenues of the municipal entity, or to private commercial entities or 501(c)(3) not-for-profit entities utilizing a pass-through municipal entity to achieve favorable tax treatment.
Land development loans included in the construction and land development loan class were $383.1 million at September 30, 2015 and $484.9 million at December 31, 2014.
Loans with a carrying value of approximately $22.3 billion at September 30, 2015 and $22.5 billion at December 31, 2014 have been pledged at the Federal Reserve and various Federal Home Loan Banks (“FHLBs”) as collateral for potential borrowings.
We sold loans with a carrying value of $434.1 million and $1,070.2 million for the three and nine months ended September 30, 2015, and $341.3 million and $939.0 million, for the three and nine months ended September 30, 2014, respectively, that were classified as loans held for sale. The sold loans were derecognized from the balance sheet. Loans classified as loans held for sale primarily consist of conforming residential mortgages and the guaranteed portion of SBA loans. The principal balance of sold loans for which we retain servicing was approximately $1.2 billion at both September 30, 2015 and December 31, 2014.

Amounts added to loans held for sale during these periods were $442.4 million and $1,111.0 million for the three and nine months ended September 30, 2015, and $297.8 million and $894.9 million for the three and nine months ended September 30, 2014, respectively. Income from loans sold, excluding servicing, was $5.0 million and $13.9 million for the three and nine months ended September 30, 2015, and $4.2 million and $11.3 million for the three and nine months ended September 30, 2014, respectively.

Since 2009, CB&T and NSB have had loss sharing agreements with the Federal Deposit Insurance Corporation (“FDIC”), which provided indemnification for credit losses of acquired loans and foreclosed assets up to specified thresholds. The last of the agreements for commercial loans, which comprised the major portion of the acquired portfolio, expired as of September 30, 2014. The agreements for 1-4 family residential loans will expire in 2019. In previous periods, the FDIC-supported loan balances were presented separately in this footnote and in other disclosures, and included purchased credit-impaired (“PCI”) loans, as subsequently discussed in Purchased Loans. Due to declining balances, for all periods presented herein, the FDIC-supported/PCI loans have been reclassified to their respective loan segments and classes.

Allowance for Credit Losses
The allowance for credit losses (“ACL”) consists of the allowance for loan and lease losses (“ALLL”) (also referred to as the allowance for loan losses) and the reserve for unfunded lending commitments (“RULC”).

Allowance for Loan and Lease Losses
The ALLL represents our estimate of probable and estimable losses inherent in the loan and lease portfolio as of the balance sheet date. Losses are charged to the ALLL when recognized. Generally, commercial and CRE loans are charged off or charged down when they are determined to be uncollectible in whole or in part, or when 180 days past due unless the loan is well secured and in process of collection. Consumer loans are either charged off or charged down to net realizable value no later than the month in which they become 180 days past due. Closed-end consumer loans that are not secured by residential real estate are either charged off or charged down to net realizable value no later than the month in which they become 120 days past due. We establish the amount of the ALLL by analyzing the portfolio at least quarterly, and we adjust the provision for loan losses so the ALLL is at an appropriate level at the balance sheet date.

We determine our ALLL as the best estimate within a range of estimated losses. The methodologies we use to estimate the ALLL depend upon the impairment status and portfolio segment of the loan. The methodology for impaired loans is discussed subsequently. For the commercial and CRE segments, we use a comprehensive loan grading system to assign probability of default (“PD”) and loss given default (“LGD”) grades to each loan. The credit quality indicators discussed subsequently are based on this grading system. In addition, loan officers utilize their experience and judgment in assigning PD and LGD grades, subject to confirmation of the PD and LGD by either credit risk or credit examination. We create groupings of these grades for each subsidiary bank and loan class and calculate historic loss rates using a loss migration analysis that attributes historic realized losses to these loan grade groupings over the period of January 2008 through the most recent full quarter.
For the consumer loan segment, we use roll rate models to forecast probable inherent losses. Roll rate models measure the rate at which consumer loans migrate from one delinquency category to the next worse delinquency category, and eventually to loss. We estimate roll rates for consumer loans using recent delinquency and loss experience by segmenting our consumer loan portfolio into separate pools based on common risk characteristics and separately calculating historical delinquency and loss experience for each pool. These roll rates are then applied to current delinquency levels to estimate probable inherent losses. When long-term average losses exceed those losses estimated through roll rates, we use long-term average loss rates for the applicable pools. Roll rates incorporate housing market trends inasmuch as these trends manifest themselves in charge-offs and delinquencies. In addition, our qualitative and environmental factors discussed subsequently incorporate the most recent housing market trends.
The current status and historical changes in qualitative and environmental factors may not be reflected in our quantitative models. Thus, after applying historical loss experience, as described above, we review the quantitatively derived level of ALLL for each segment using qualitative criteria and use those criteria to determine our estimate within the range. We track various risk factors that influence our judgment regarding the level of the ALLL across the portfolio segments. These factors primarily include:
Asset quality trends
Risk management and loan administration practices
Risk identification practices
Effect of changes in the nature and volume of the portfolio
Existence and effect of any portfolio concentrations
National economic and business conditions
Regional and local economic and business conditions
Data availability and applicability
Effects of other external factors
The magnitude of the impact of these factors on our qualitative assessment of the ALLL changes from quarter to quarter according to changes made by management in its assessment of these factors, the extent these factors are already reflected in historic loss rates, and the extent changes in these factors diverge from one to another. We also consider the uncertainty inherent in the estimation process when evaluating the ALLL.

Reserve for Unfunded Lending Commitments
We also estimate a reserve for potential losses associated with off-balance sheet commitments, including standby letters of credit. We determine the RULC using the same procedures and methodologies that we use for the ALLL. The loss factors used in the RULC are the same as the loss factors used in the ALLL, and the qualitative adjustments used in the RULC are the same as the qualitative adjustments used in the ALLL. We adjust the Company’s unfunded lending commitments that are not unconditionally cancelable to an outstanding amount equivalent using credit conversion factors, and we apply the loss factors to the outstanding equivalents.
Changes in the allowance for credit losses are summarized as follows:

Nonaccrual and Past Due Loans
Loans are generally placed on nonaccrual status when payment in full of principal and interest is not expected, or the loan is 90 days or more past due as to principal or interest, unless the loan is both well secured and in the process of collection. Factors we consider in determining whether a loan is placed on nonaccrual include delinquency status, collateral value, borrower or guarantor financial statement information, bankruptcy status, and other information which would indicate that the full and timely collection of interest and principal is uncertain.
A nonaccrual loan may be returned to accrual status when all delinquent interest and principal become current in accordance with the terms of the loan agreement; the loan, if secured, is well secured; the borrower has paid according to the contractual terms for a minimum of six months; and analysis of the borrower indicates a reasonable assurance of the ability and willingness to maintain payments. Payments received on nonaccrual loans are applied as a reduction to the principal outstanding.
Closed-end loans with payments scheduled monthly are reported as past due when the borrower is in arrears for two or more monthly payments. Similarly, open-end credit such as charge-card plans and other revolving credit plans are reported as past due when the minimum payment has not been made for two or more billing cycles. Other multi-payment obligations (i.e., quarterly, semiannual, etc.), single payment, and demand notes are reported as past due when either principal or interest is due and unpaid for a period of 30 days or more.

Represents nonaccrual loans that are not past due more than 30 days; however, full payment of principal and interest is still not expected.

Credit Quality Indicators
In addition to the past due and nonaccrual criteria, we also analyze loans using loan risk grading systems, which vary based on the size and type of credit risk exposure. The internal risk grades assigned to loans follow our definitions of Pass, Special Mention, Substandard, and Doubtful, which are consistent with published definitions of regulatory risk classifications.

Definitions of Pass, Special Mention, Substandard, and Doubtful are summarized as follows:
Pass – A Pass asset is higher quality and does not fit any of the other categories described below. The likelihood of loss is considered remote.
Special Mention A Special Mention asset has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the bank’s credit position at some future date.
Substandard – A Substandard asset is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified have well-defined weaknesses and are characterized by the distinct possibility that the bank may sustain some loss if deficiencies are not corrected.
Doubtful – A Doubtful asset has all the weaknesses inherent in a Substandard asset with the added characteristics that the weaknesses make collection or liquidation in full highly questionable and improbable.

We generally assign internal risk grades to commercial and CRE loans with commitments equal to or greater than $750,000 based on financial and statistical models, individual credit analysis, and loan officer judgment. For these larger loans, we assign one of multiple grades within the Pass classification or one of the following four grades: Special Mention, Substandard, Doubtful, and Loss. Loss indicates that the outstanding balance has been charged off. We confirm our internal risk grades quarterly, or as soon as we identify information that affects the credit risk of the loan.

For consumer loans or certain small commercial loans with commitments equal to or less than $750,000, we generally assign internal risk grades similar to those described previously based on automated rules that depend on refreshed credit scores, payment performance, and other risk indicators. These are generally assigned either a Pass or Substandard grade and are reviewed as we identify information that might warrant a grade change.

Outstanding loan balances (accruing and nonaccruing) categorized by these credit quality indicators are summarized as follows:

Impaired Loans
Loans are considered impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due in accordance with the contractual terms of the loan agreement, including scheduled interest payments. For our non-purchased credit-impaired loans, if a nonaccrual loan has a balance greater than $1 million, or if a loan is a troubled debt restructuring (“TDR”), including TDRs that subsequently default, or if the loan is no longer reported as a TDR, we individually evaluate the loan for impairment and estimate a specific reserve for the loan for all portfolio segments under applicable accounting guidance. Smaller nonaccrual loans are pooled for ALLL estimation purposes. PCI loans are included in impaired loans and are accounted for under separate accounting guidance. See subsequent discussion under Purchased Loans.

When a loan is impaired, we estimate a specific reserve for the loan based on the projected present value of the loan’s future cash flows discounted at the loan’s effective interest rate, the observable market price of the loan, or the fair value of the loan’s underlying collateral. The process of estimating future cash flows also incorporates the same determining factors discussed previously under nonaccrual loans. When we base the impairment amount on the fair value of the loan’s underlying collateral, we generally charge off the portion of the balance that is impaired, such that these loans do not have a specific reserve in the ALLL. Payments received on impaired loans that are accruing are recognized in interest income, according to the contractual loan agreement. Payments received on impaired loans that are on nonaccrual are not recognized in interest income, but are applied as a reduction to the principal outstanding. The amount of interest income recognized on a cash basis during the time the loans were impaired within the three and nine months ended September 30, 2015 and 2014 was not significant.

Information on impaired loans individually evaluated is summarized as follows at September 30, 2015 and December 31, 2014, including the average recorded investment and interest income recognized for the three and nine months ended September 30, 2015 and 2014:

Modified and Restructured Loans
Loans may be modified in the normal course of business for competitive reasons or to strengthen the Company’s position. Loan modifications and restructurings may also occur when the borrower experiences financial difficulty and needs temporary or permanent relief from the original contractual terms of the loan. These modifications are structured on a loan-by-loan basis and, depending on the circumstances, may include extended payment terms, a modified interest rate, forgiveness of principal, or other concessions. Loans that have been modified to accommodate a borrower who is experiencing financial difficulties, and for which the Company has granted a concession that it would not otherwise consider, are considered TDRs.

We consider many factors in determining whether to agree to a loan modification involving concessions, and seek a solution that will both minimize potential loss to the Company and attempt to help the borrower. We evaluate borrowers’ current and forecasted future cash flows, their ability and willingness to make current contractual or proposed modified payments, the value of the underlying collateral (if applicable), the possibility of obtaining additional security or guarantees, and the potential costs related to a repossession or foreclosure and the subsequent sale of the collateral.

TDRs are classified as either accrual or nonaccrual loans. A loan on nonaccrual and restructured as a TDR will remain on nonaccrual status until the borrower has proven the ability to perform under the modified structure for a minimum of six months, and there is evidence that such payments can and are likely to continue as agreed. Performance prior to the restructuring, or significant events that coincide with the restructuring, are included in assessing whether the borrower can meet the new terms and may result in the loan being returned to accrual at the time of restructuring or after a shorter performance period. If the borrower’s ability to meet the revised payment schedule is uncertain, the loan remains classified as a nonaccrual loan. A TDR loan that specifies an interest rate that at the time of the restructuring is greater than or equal to the rate the bank is willing to accept for a new loan with comparable risk may not be reported as a TDR or an impaired loan in the calendar years subsequent to the restructuring if it is in compliance with its modified terms.

Selected information on TDRs that includes the recorded investment on an accruing and nonaccruing basis by loan class and modification type is summarized in the following schedules:

Calculated based on the difference between the modified rate and the premodified rate applied to the recorded investment.
On an ongoing basis, we monitor the performance of all TDRs according to their restructured terms. Subsequent payment default is defined in terms of delinquency, when principal or interest payments are past due 90 days or more for commercial loans, or 60 days or more for consumer loans.
The recorded investment of accruing and nonaccruing TDRs that had a payment default during the period listed below (and are still in default at period end) and are within 12 months or less of being modified as TDRs is as follows:

Note: Total loans modified as TDRs during the 12 months previous to September 30, 2015 and 2014 were $93.4 million and $97.3 million, respectively.

As of September 30, 2015, the amount of foreclosed residential real estate property held by the Company was approximately $1.6 million, and the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure was approximately $9.3 million.

Concentrations of Credit Risk
Credit risk is the possibility of loss from the failure of a borrower, guarantor, or another obligor to fully perform under the terms of a credit-related contract. Credit risks (whether on- or off-balance sheet) may occur when individual borrowers, groups of borrowers, or counterparties have similar economic characteristics, including industries, geographies, collateral types, sponsors, etc., and are similarly affected by changes in economic or other conditions. Credit risk also includes the loss that would be recognized subsequent to the reporting date if counterparties failed to perform as contracted. See Note 7 for a discussion of counterparty risk associated with the Company’s derivative transactions.

We perform an ongoing analysis of our loan portfolio to evaluate whether there is any significant exposure to any concentrations of credit risk. Based on this analysis, we believe that the loan portfolio is generally well diversified; however, there are certain significant concentrations in CRE and energy-related lending. Further, we cannot guarantee that we have fully understood or mitigated all risk concentrations or correlated risks. We have adopted and adhere to concentration limits on various types of CRE lending, particularly construction and land development lending, leveraged and enterprise value lending, municipal lending, and energy-related lending. All of these limits are continually monitored and revised as necessary.

Purchased Loans
Background and Accounting
We purchase loans in the ordinary course of business and account for them and the related interest income based on their performing status at the time of acquisition. PCI loans have evidence of credit deterioration at the time of acquisition and it is probable that not all contractual payments will be collected. Interest income for PCI loans is accounted for on an expected cash flow basis. Certain other loans acquired by the Company that are not credit-impaired include loans with revolving privileges and are excluded from the PCI tabular disclosures following. Interest income for these loans is accounted for on a contractual cash flow basis. Upon acquisition, in accordance with applicable accounting guidance, the acquired loans were recorded at their fair value without a corresponding ALLL. Certain acquired loans with similar characteristics such as risk exposure, type, size, etc., are grouped and accounted for in loan pools.

Outstanding Balances and Accretable Yield
The outstanding balances of all required payments and the related carrying amounts for PCI loans are as follows:

At the time of acquisition of PCI loans, we determine the loan’s contractually required payments in excess of all cash flows expected to be collected as an amount that should not be accreted (nonaccretable difference). With respect to the cash flows expected to be collected, the portion representing the excess of the loan’s expected cash flows over our initial investment (accretable yield) is accreted into interest income on a level yield basis over the remaining expected life of the loan or pool of loans. The effects of estimated prepayments are considered in estimating the expected cash flows.

Certain PCI loans are not accounted for as previously described because the estimation of cash flows to be collected involves a high degree of uncertainty. Under these circumstances, the accounting guidance provides that interest income is recognized on a cash basis similar to the cost recovery methodology for nonaccrual loans. The net carrying amounts in the preceding schedule also include the amounts for these loans. There were no amounts of these loans at September 30, 2015 and $5.3 million at December 31, 2014.
Changes in the accretable yield for PCI loans were as follows:

Note: Amounts have been adjusted based on refinements to the original estimates of the accretable yield.
The primary drivers of reclassification to accretable yield from nonaccretable difference and increases in disposals and other resulted primarily from (1) changes in estimated cash flows, (2) unexpected payments on nonaccrual loans, and (3) recoveries on zero balance loans pools. See subsequent discussion under changes in cash flow estimates.

ALLL Determination
For all acquired loans, the ALLL is only established for credit deterioration subsequent to the date of acquisition and represents our estimate of the inherent losses in excess of the book value of acquired loans. The ALLL for acquired loans is included in the overall ALLL in the balance sheet.

During the three and nine months ended September 30, 2015, we adjusted the ALLL for acquired loans by recording a provision for loan losses of $0.8 million and $0.3 million, respectively. No adjustment was made during the three months ended September 30, 2014 and $(2.5) million was made during the nine months ended September 30, 2014. The provision is net of the ALLL reversals discussed subsequently.

Changes in the provision for loan losses and related ALLL are driven in large part by the same factors that affect the changes in reclassification from nonaccretable difference to accretable yield, as discussed under changes in cash flow estimates.

Changes in Cash Flow Estimates
Over the life of the loan or loan pool, we continue to estimate cash flows expected to be collected. We evaluate quarterly at the balance sheet date whether the estimated present values of these loans using the effective interest rates have decreased below their carrying values. If so, we record a provision for loan losses.

For increases in carrying values that resulted from better-than-expected cash flows, we use such increases first to reverse any existing ALLL. During the three and nine months ended September 30, total reversals to the ALLL, including the impact of increases in estimated cash flows, were $0.6 million and $3.1 million in 2015 and $0.8 million and $4.4 million in 2014, respectively. When there is no current ALLL, we increase the amount of accretable yield on a prospective basis over the remaining life of the loan and recognize this increase in interest income.

For the three and nine months ended September 30, the impact of increased cash flow estimates recognized in the statement of income for acquired loans with no ALLL was approximately $5.4 million and $22.1 million in 2015 and $7.7 million and $37.9 million in 2014, respectively, of additional interest income.
