Net loans include net discounts on acquired loans of $42.3 million and $43.7 million as of March 31, 2016 and December 31, 2015 , respectively. Purchased credit-impaired loans and purchased non-credit-impaired loans. Purchased loans, including loans acquired in business combinations, are recorded at their fair value at the acquisition date. Credit discounts are included in the determination of fair value; therefore, an allowance for loan and lease losses is not recorded at the acquisition date. Acquired loans are evaluated upon acquisition and classified as either purchased credit-impaired or purchased non-credit-impaired. PCI loans reflect credit deterioration since origination such that it is probable at acquisition that the Company will be unable to collect all contractually required payments. The outstanding contractual unpaid principal balance of purchased credit-impaired loans, excluding acquisition accounting adjustments, was $76.6 million at March 31, 2016 and $83.4 million at December 31, 2015 . The carrying balance of purchased credit-impaired loans was $53.3 million at March 31, 2016 and $58.6 million at December 31, 2015 . The following table presents the changes in the accretable yield for purchased credit-impaired loans for the three months ended March 31, 2016 and 2015 (in thousands): Three Months Ended 2016 2015 Balance, beginning of period $ 10,375 $ — Additions — 2,239 Accretion to interest income (1,931 ) (35 ) Disposals (18 ) — Reclassifications from non-accretable difference 2,291 — Balance, end of period $ 10,717 $ 2,204 As of March 31, 2016 and December 31, 2015 , the non-accretable difference between the contractually required payments and cash flows expected to be collected were $25.3 million and $29.5 million , respectively. Impaired Loans and the Allowance for Loan Losses. A loan is considered impaired when, based on current information and circumstances, the Company determines it is probable that it will be unable to collect all amounts due according to the contractual terms of the loan agreement, including scheduled interest payments. Factors involved in determining impairment include, but are not limited to, the financial condition of the borrower, the value of the underlying collateral and the current status of the economy. Impaired loans are comprised of loans on nonaccrual, troubled debt restructures (TDRs) that are performing under their restructured terms, and loans that are 90 days or more past due, but are still on accrual. Purchased credit-impaired loans are considered performing within the scope of the purchased credit-impaired accounting guidance and are not included in the impaired loan tables. The following tables provide information on impaired loans, excluding purchased credit impaired loans, with and without allowance reserves at March 31, 2016 and December 31, 2015 .

(2) Includes general reserves for loans evaluated in pools of homogeneous loans and loans with a specific allowance reserve. Loans with a specific allowance reserve have been individually evaluated for impairment using either a discounted cash flow analysis or, for collateral dependent loans, current appraisals less costs to sell to establish realizable value. The following tables summarize our average recorded investment and interest income recognized on impaired loans by loan class for the three months ended March 31, 2016 and 2015 (in thousands): Three Months Ended Three Months Ended Average Recorded Investment Interest Income Recognized Average Recorded Investment Interest Income Recognized Commercial real estate: Owner-occupied $ 2,116 $ 4 $ 2,698 $ 3 Investment properties 8,415 75 6,490 77 Multifamily real estate 356 4 975 11 Commercial construction — — — — One- to four-family construction 1,610 27 3,097 31 Land and land development: Residential 1,988 10 2,547 16 Commercial 1,027 — 1,624 — Commercial business 2,495 8 1,172 9 Agricultural business/farmland 1,215 5 2,317 5 One- to four-family residential 15,181 126 24,025 204 Consumer: Consumer secured by one- to four-family 1,042 3 1,209 3 Consumer—other 455 4 773 4 $ 35,900 $ 266 $ 46,927 $ 363 Troubled Debt Restructures (TDRs). Some of the Company’s loans are reported as TDRs. Loans are reported as TDRs when the bank grants one or more concessions to a borrower experiencing financial difficulties that it would not otherwise consider. Examples of such concessions include forgiveness of principal or accrued interest, extending the maturity date(s) or providing a lower interest rate than would be normally available for a transaction of similar risk. Our TDRs have generally not involved forgiveness of amounts due, but almost always include a modification of multiple factors; the most common combination includes interest rate, payment amount and maturity date. As a result of these concessions, restructured loans are impaired as the Company will not collect all amounts due, both principal and interest, in accordance with the terms of the original loan agreement. Loans identified as TDRs are accounted for in accordance with the Company's impaired loan accounting policies. The following tables present TDRs at March 31, 2016 and December 31, 2015 (in thousands): March 31, 2016 Accrual Status Nonaccrual Status Total TDRs Commercial real estate: Owner-occupied $ 181 $ 102 $ 283 Investment properties 5,792 6 5,798 Multifamily real estate 355 — 355 Commercial construction — — — One- to four-family construction 1,644 — 1,644 Land and land development: Residential 762 472 1,234 Commercial — — — Commercial business 561 — 561 Agricultural business, including secured by farmland 563 243 806 One- to four-family residential 9,277 1,401 10,678 Consumer: Consumer secured by one- to four-family 146 12 158 Consumer—other 169 — 169 $ 19,450 $ 2,236 $ 21,686 December 31, 2015 Accrual Status Nonaccrual Status Total TDRs Commercial real estate: Owner-occupied $ 181 $ 104 $ 285 Investment properties 5,834 13 5,847 Multifamily real estate 357 — 357 One- to four-family construction 1,741 — 1,741 Land and land development: Residential 1,151 483 1,634 Commercial business 624 — 624 Agricultural business, including secured by farmland 545 277 822 One- to four-family residential 11,025 1,428 12,453 Consumer: Consumer secured by one- to four-family 147 14 161 Consumer—other 172 — 172 $ 21,777 $ 2,319 $ 24,096 As of March 31, 2016 and December 31, 2015 , the Company had commitments to advance funds related to TDRs up to additional amounts of $197,000 and $237,000 , respectively. No new TDRs occurred during the three months ended March 31, 2016 . The following table presents new TDRs that occurred during the three months ended March 31, 2015 (dollars in thousands): Three Months Ended March 31, 2015 Number of Contracts Pre-modification Outstanding Recorded Investment Post-modification Outstanding Recorded Investment Recorded Investment (1) (2) One- to four-family construction 2 592 592 Agricultural business/farmland 2 288 288 4 $ 880 $ 880 (1) Since these loans were already considered classified and/or on nonaccrual status prior to restructuring, the modifications did not have a material effect on the Company’s determination of the allowance for loan losses. (2) The majority of these modifications do not fit into one separate type, such as rate, term, amount, interest-only or payment, but instead are a combination of multiple types of modifications; therefore, they are disclosed in aggregate. There were no TDRs which incurred a payment default within twelve months of the restructure date during the three -month periods ended March 31, 2016 and 2015 . A default on a TDR results in either a transfer to nonaccrual status or a partial charge-off, or both. Credit Quality Indicators : To appropriately and effectively manage the ongoing credit quality of the Company’s loan portfolio, management has implemented a risk-rating or loan grading system for its loans. The system is a tool to evaluate portfolio asset quality throughout each applicable loan’s life as an asset of the Company. Generally, loans and leases are risk rated on an aggregate borrower/relationship basis with individual loans sharing similar ratings. There are some instances when specific situations relating to individual loans will provide the basis for different risk ratings within the aggregate relationship. Loans are graded on a scale of 1 to 9. A description of the general characteristics of these categories is shown below: Overall Risk Rating Definitions : Risk-ratings contain both qualitative and quantitative measurements and take into account the financial strength of a borrower and the structure of the loan or lease. Consequently, the definitions are to be applied in the context of each lending transaction and judgment must also be used to determine the appropriate risk rating, as it is not unusual for a loan or lease to exhibit characteristics of more than one risk-rating category. Consideration for the final rating is centered in the borrower’s ability to repay, in a timely fashion, both principal and interest. There were no material changes in the risk-rating or loan grading system in the three months ended March 31, 2016 . Risk Rating 1: Exceptional A credit supported by exceptional financial strength, stability, and liquidity. The risk rating of 1 is reserved for the Company’s top quality loans, generally reserved for investment grade credits underwritten to the standards of institutional credit providers. Risk Rating 2: Excellent A credit supported by excellent financial strength, stability and liquidity. The risk rating of 2 is reserved for very strong and highly stable customers with ready access to alternative financing sources. Risk Rating 3: Strong A credit supported by good overall financial strength and stability. Collateral margins are strong; cash flow is stable although susceptible to cyclical market changes. Risk Rating 4: Acceptable A credit supported by the borrower’s adequate financial strength and stability. Assets and cash flow are reasonably sound and provide for orderly debt reduction. Access to alternative financing sources will be more difficult to obtain. Risk Rating 5: Watch A credit with the characteristics of an acceptable credit which requires, however, more than the normal level of supervision and warrants formal quarterly management reporting. Credits in this category are not yet criticized or classified, but due to adverse events or aspects of underwriting require closer than normal supervision. Generally, credits should be watch credits in most cases for six months or less as the impact of stress factors are analyzed. Risk Rating 6: Special Mention A credit with potential weaknesses that deserves management’s close attention is risk rated a 6. If left uncorrected, these potential weaknesses will result in deterioration in the capacity to repay debt. A key distinction between Special Mention and Substandard is that in a Special Mention credit, there are identified weaknesses that pose potential risk(s) to the repayment sources, versus well defined weaknesses that pose risk(s) to the repayment sources. Assets in this category are expected to be in this category no more than 9 - 12 months as the potential weaknesses in the credit are resolved. Risk Rating 7: Substandard A credit with well defined weaknesses that jeopardize the ability to repay in full is risk rated a 7. These credits are inadequately protected by either the sound net worth and payment capacity of the borrower or the value of pledged collateral. These are credits with a distinct possibility of loss. Loans headed for foreclosure and/or legal action due to deterioration are rated 7 or worse. Risk Rating 8: Doubtful A credit with an extremely high probability of loss is risk rated 8. These credits have all the same critical weaknesses that are found in a substandard loan; however, the weaknesses are elevated to the point that based upon current information, collection or liquidation in full is improbable. While some loss on doubtful credits is expected, pending events may strengthen a credit making the amount and timing of any loss indeterminable. In these situations taking the loss is inappropriate until it is clear that the pending event has failed to strengthen the credit and improve the capacity to repay debt. Risk Rating 9: Loss A credit that is considered to be currently uncollectible or of such little value that it is no longer a viable Bank asset is risk rated 9. Losses should be taken in the accounting period in which the credit is determined to be uncollectible. Taking a loss does not mean that a credit has absolutely no recovery or salvage value but, rather, it is not practical or desirable to defer writing off the credit, even though partial recovery may occur in the future.
