Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
Nature of Operations and Summary of Significant Accounting and Reporting Policies | 1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING POLICIES Nature of Operations —Prosperity Bancshares, Inc. ® ® As of December 31, 2017, the Bank operated 242 full-service banking locations; with 65 in the Houston area, including The Woodlands; 29 in the South Texas area including Corpus Christi and Victoria; 33 in the Dallas/Fort Worth, Texas area; 22 in the East Texas area; 29 in the Central Texas area, including Austin and San Antonio; 34 in the West Texas area including Lubbock, Midland-Odessa and Abilene; 16 in the Bryan/College Station area; 6 in the Central Oklahoma area; and 8 in the Tulsa, Oklahoma area. Summary of Significant Accounting and Reporting Policies —The accounting and reporting policies of the Company conform to generally accepted accounting principles (“GAAP”) and the prevailing practices within the financial services industry. A summary of significant accounting and reporting policies are as follows: Basis of Presentation —The consolidated financial statements include the accounts of Bancshares and its subsidiaries. Intercompany transactions have been eliminated in consolidation. Operations are managed and financial performance is evaluated on a company-wide basis. Accordingly, all of the Company’s banking operations are considered by management to be aggregated in one reportable operating segment. Because the overall banking operations comprise the vast majority of the consolidated operations, no separate segment disclosures are presented. Use of Estimates —The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Such estimates include, but are not limited to certain fair value measures including the calculation of stock-based compensation, the valuation of goodwill and available for sale and held to maturity securities and the calculation of allowance for credit losses. Actual results could differ from these estimates. Securities —Securities held to maturity are carried at cost, adjusted for the amortization of premiums and the accretion of discounts. Management has the positive intent and the Company has the ability to hold these assets until their estimated maturities. Securities available for sale are carried at fair value. Unrealized gains and losses are excluded from earnings and reported, net of tax, as a separate component of shareholders’ equity until realized. Securities within the available for sale portfolio may be used as part of the Company’s asset/liability strategy and may be sold in response to changes in interest rate risk, prepayment risk or other similar economic factors. For debt securities, when other-than-temporary impairment (“OTTI”) occurs, the amount of the OTTI recognized in earnings depends on whether an entity intends to sell the security or more likely than not will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss. If an entity intends to sell or more likely than not will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss, the OTTI will be recognized in earnings equal to the entire difference between the investment’s amortized cost basis and its fair value at the balance sheet date. If an entity does not intend to sell the security and it is not more likely than not that the entity will be required to sell the security before recovery of its amortized cost basis less any current-period loss, the OTTI will be separated into the amount representing the credit-related portion of the impairment loss (“credit loss”) and the noncredit portion of the impairment loss (“noncredit portion”). The amount of the total OTTI related to the credit loss is determined based on the difference between the present value of cash flows expected to be collected and the amortized cost basis and such difference is recognized in earnings. The amount of the total OTTI related to the noncredit portion is recognized in other comprehensive income, net of applicable taxes. The previous amortized cost basis less the OTTI recognized in earnings shall become the new amortized cost basis of the investment. Premiums and discounts are amortized and accreted to operations using the level-yield method of accounting, adjusted for prepayments as applicable. The specific identification method of accounting is used to compute gains or losses on the sales of these assets. Interest earned on these assets is included in interest income. Loans Held for Sale —Loans held for sale are carried at the lower of aggregate cost or market value. Premiums, discounts and loan fees (net of certain direct loan origination costs) on loans held for sale are deferred until the related loans are sold or repaid. Gains or losses on loan sales are recognized at the time of sale and determined using the specific identification method. Loans Held for Investment —Loans originated and held for investment are stated at the principal amount outstanding, net of unearned fees. The related interest income for multipayment loans is recognized principally by the simple interest method; for single payment loans, such income is recognized using the straight-line method. The Company has two general categories of loans in its portfolio. Loans originated by the Bank and made pursuant to the Company’s loan policy and procedures in effect at the time the loan was made are referred to as “legacy loans” and loans acquired in a business combination are referred to as “acquired loans.” Acquired loans are initially recorded at fair value based on a discounted cash flow valuation methodology that considers, among other things, interest rates, projected default rates, loss given default and recovery rates, with no carryover of any existing allowance for credit losses. Those acquired loans that are renewed or substantially modified after the date of the business combination, thereby subjecting them to the Company’s allowance for credit losses methodology, are referred to as “acquired legacy loans.” Modifications are reviewed for determination of troubled debt restructuring status independently of this process. In certain instances, acquired loans to one borrower may be combined or otherwise re-originated such that they are re-categorized as legacy loans. Acquired loans with a fair value discount or premium at the date of the business combination that remained at the reporting date are referred to as “fair-valued acquired loans.” All fair-valued acquired loans are further categorized into “Non-PCI loans” and “PCI loans” (purchased credit impaired loans). Acquired loans with evidence of credit quality deterioration at acquisition are reviewed to determine if it is probable that the Company will not be able to collect all contractual amounts due, including both principal and interest. When both conditions exist, such loans are accounted for as PCI loans. The Company estimates the total cash flows expected to be collected from the PCI loans, which include undiscounted expected principal and interest, using credit risk, interest rate and prepayment risk assessments that incorporate management’s best estimate of current key assumptions such as default rates, loss severity and payment speeds. The excess of the undiscounted total cash flows expected to be collected over the fair value of the related PCI loans represents the accretable yield, which is recognized as interest income on a level-yield basis over the life of the related loan. The difference between the undiscounted contractual principal and interest and the undiscounted total cash flows expected to be collected is the nonaccretable difference, which reflects the impact of estimated credit losses and other factors. Subsequent increases in expected cash flows will result in a recovery of any previously recorded allowance for credit losses, to the extent applicable, and a reclassification from nonaccretable difference to accretable yield, which is recognized prospectively over the then remaining life of the loan. Subsequent decreases in expected cash flows will result in an impairment charge to the provision for credit losses, resulting in an addition to the allowance for credit losses, and a reclassification from accretable yield to nonaccretable difference. A loan disposal, which may include a loan sale, receipt of payment in full from the borrower or foreclosure, results in removal of the loan from the balance sheet at its allocated carrying amount and accretion of any remaining fair value discount to income. Nonrefundable Fees and Costs Associated with Lending Activities —Loan origination fees in excess of the associated costs are recognized over the life of the related loan as an adjustment to yield using the interest method. Loan commitment fees and loan origination costs are deferred and recognized as an adjustment of yield by the interest method over the related loan life or, if the commitment expires unexercised, recognized in income upon expiration of the commitment. Nonperforming and Past Due Loans —Included in the nonperforming loan category are loans which have been categorized by management as nonaccrual because collection of interest is doubtful and loans which have been restructured to provide a reduction in the interest rate or a deferral of interest or principal payments. When the payment of principal or interest on a loan is delinquent for 90 days, or earlier in some cases, the loan is placed on nonaccrual status unless the loan is in the process of collection and the underlying collateral fully supports the carrying value of the loan. If the decision is made to continue accruing interest on the loan, periodic reviews are made to confirm the accruing status of the loan. When a loan is placed on nonaccrual status, interest accrued but not yet collected prior to the determination of uncollectibility is charged to operations. Interest accrued during prior periods is charged to the allowance for credit losses. Any payments received on nonaccrual loans are applied first to outstanding principal of the loan amount, next to the recovery of charged-off loan amounts and finally, any excess is treated as recovery of lost interest. Restructured loans are those loans on which concessions in terms have been granted because of a borrower’s financial difficulty. Interest is generally not accrued on such loans in accordance with the new terms. Allowance for Credit Losses —The allowance for credit losses is a valuation allowance available for losses incurred on loans. All losses are charged to the allowance when the loss actually occurs or when a determination is made that such a loss is probable and reasonably estimatable. Recoveries are credited to the allowance at the time of recovery. Throughout the year, management estimates the probable level of losses to determine whether the allowance for credit losses is adequate to absorb losses inherent in the loan portfolio. Based on these estimates, an amount is charged to the provision for credit losses and credited to the allowance for credit losses in order to adjust the allowance to a level determined to be adequate to absorb losses. In making its evaluation of the adequacy of the allowance for credit losses, management considers factors such as historical loan loss experience, the amount of nonperforming assets and related collateral, the volume, growth and composition of the Company’s loan portfolio, current economic conditions that may affect the borrower’s ability to pay and the value of collateral, the evaluation of the Company’s loan portfolio through its internal loan review process and other relevant factors. Estimates of credit losses involve an exercise of judgment. While it is possible that in the short term the Company may sustain losses which are substantial in relation to the allowance for credit losses, it is the judgment of management that the allowance for credit losses reflected in the consolidated balance sheets is adequate to absorb probable losses that exist in the loan portfolio as of December 31, 2017. The Company’s allowance for credit losses consists of two elements: (1) specific valuation allowances based on probable losses on impaired loans; and (2) a general valuation allowance based on historical loan loss experience, general economic conditions and other qualitative risk factors both internal and external to the Company. A loan is defined as impaired if, based on current information and events, it is probable that a creditor will be unable to collect all amounts due, both interest and principal, according to the contractual terms of the loan agreement. The allowance for credit losses related to impaired loans is determined based on the difference of carrying value of loans and the present value of expected cash flows discounted at the loan’s effective interest rate or, as a practical expedient, the loan’s observable market price or the fair value of the collateral if the loan is collateral dependent. Loans acquired in business combinations are initially recorded at fair value, which includes an estimate of credit losses expected to be realized over the remaining lives of the loans, and therefore no corresponding allowance for credit losses is recorded for these loans at acquisition. These fair value estimates associated with acquired loans, based on a discounted cash flow model, include estimates related to market interest rates and undiscounted projections of future cash flows that incorporate expectations of prepayments and the amount and timing of principal, interest and other cash flows, as well as any shortfalls thereof. At period-end after acquisition, the fair-valued acquired loans from each acquisition are reassessed to determine whether an addition to the allowance for credit losses is appropriate due to further credit quality deterioration. Methods utilized to estimate any subsequently required allowance for acquired loans not deemed credit impaired at acquisition are similar to originated loans; however, the estimate of loss is based on the unpaid principal balance and then compared to any remaining unaccreted purchase discount. To the extent that the calculated loss is greater than the remaining unaccreted purchase discount, an allowance is recorded for such difference. Premises and Equipment —Premises and equipment are carried at cost less accumulated depreciation. Depreciation expense is computed principally using the straight-line method over the estimated useful lives of the assets which range from three to 39 years. Leasehold improvements are amortized using the straight-line method over the periods of the leases or the estimated useful lives, whichever is shorter. Goodwill —Goodwill is annually assessed for impairment or when events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. Under Accounting Standards Codification (“ASC”) topic 350-20, “Intangibles—Goodwill and Other—Goodwill” If the Company bypasses the qualitative assessment, a two-step goodwill impairment test would be performed. The first step of the goodwill impairment test compares the estimated fair value of the Company’s reporting unit to its carrying value. If the estimated fair value of the reporting unit exceeds its carrying value, goodwill of the reporting unit is not impaired. If the estimated fair value of the reporting unit is less than the carrying value, the second step must be performed to determine the implied fair value of the reporting unit’s goodwill and the amount of goodwill impairment, if any. The Company currently utilizes a qualitative assessment for its annual goodwill impairment analysis. Amortization of Core Deposit Intangibles —Core deposit intangibles are being amortized on a non-pro rata basis over an estimated life of 10 to 15 years. Income Taxes — The Company files a consolidated federal income tax return and a consolidated Oklahoma state income tax return. Since 2014, the Bank files an Arkansas state income tax return. Deferred tax assets and liabilities are recognized for the estimated tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and are recorded in other assets or other liabilities on the Company’s consolidated balance sheets. The Company records uncertain tax positions in accordance with ASC topic 740 “ Income Taxes Realization of net deferred tax assets is based upon the level of historical income and on estimates of future taxable income. Although realization is not assured, management believes it is more likely than not that all of the net deferred tax assets will be realized. Interest and/or penalties related to income taxes are reported as a component of income tax expense. Beginning in 2017, the income tax effects related to settlements of share-based payment awards are reported in earnings as an increase (or decrease) to income tax expense (see Note 11 - Income Taxes). Stock-Based Compensation —The Company accounts for stock-based employee compensation plans using the fair value-based method of accounting. The expense associated with stock-based compensation is recognized over the vesting period of each individual arrangement. The fair value of stock options granted is estimated at the date of grant using the Black-Scholes option-pricing model. This model requires the input of subjective assumptions. The fair value of restricted stock awards is based on the current market price on the date of grant. Cash and Cash Equivalents —For purposes of reporting cash flows, cash and cash equivalents include cash and due from banks as well as federal funds sold that mature in three days or less. Earnings Per Common Share —Basic earnings per common share are calculated using the two-class method. The two-class method provides that unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and shall be included in the computation of basic earnings per share. Diluted earnings per common share is computed using the weighted-average number of shares determined for the basic earnings per common share computation plus the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock using the treasury stock method. As of December 31, 2017, all outstanding stock options issued by the Company have been exercised and there is no potential dilution of weighted-average shares. The following table illustrates the computation of basic and diluted earnings per share: Year Ended December 31, 2017 2016 2015 Amount Per Share Amount Amount Per Share Amount Amount Per Share Amount (Amounts in thousands, except per share data) Net income $ 272,165 $ 274,466 $ 286,646 Basic: Weighted average shares outstanding 69,484 $ 3.92 69,674 $ 3.94 70,033 $ 4.09 Diluted: Add incremental shares for: Effect of dilutive securities - options — 6 16 Total 69,484 $ 3.92 69,680 $ 3.94 70,049 $ 4.09 There were no stock options exercisable at December 31, 2017, 2016 and 2015 that would have had an anti-dilutive effect on the above computation. New Accounting Standards Accounting Standards Updates (“ASU”) ASU 2018-02, “Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” The amendments of ASU 2018-02 allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. ASU 2018-02 is effective for all entities beginning January 1, 2019 and is not expected to have a significant impact on the Company’s financial statements. ASU 2017-04, ASU 2017-04 simplifies the subsequent measurement of goodwill by eliminating the second step of the goodwill impairment test, which required computing the implied fair value of goodwill. Under the amendments in this update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. ASU 2017-04 will be effective for the Company on January 1, 2020 and is not expected to have a significant impact on the Company’s financial statements. ASU 2017-01, ASU 2017-01 is intended to clarify or correct unintended application of ASU 2017-01 clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. Additionally, the amendments in this update provide a more robust framework to assist entities in evaluating whether a set of assets and activities constitutes a business. Lastly, the amendments in this update narrow the definition of the term output so that the term is consistent with how outputs are described in Topic 606. ASU 2017-01 is effective for the Company on January 1, 2018 and is not expected to have a significant impact on the Company’s financial statements. ASU 2016-18, ASU 2016-18 requires the Statement of Cash Flows to explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. Therefore, restricted cash or cash equivalents should be included with cash and cash equivalents when recording the beginning-of-period and end-of-period total amounts on the Statement of Cash Flows. ASU 2016-18 is effective for the Company on January 1, 2018 and is not expected to have a significant impact on the Company’s financial statements. ASU 2016-15, ASU 2016-15 addresses certain cash receipts and cash payments with the objective of reducing the existing diversity in practice. ASU 2016-15 is effective for the Company on January 1, 2018 and is not expected to have a significant impact on the Company's financial statements. ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326)—Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 requires a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. An entity must use judgment in determining the relevant information and estimation methods that are appropriate in its circumstances. Additionally, available for sale debt securities may realize value either through collection of contractual cash flows or through sale of the security at fair value. Therefore, the amendments limit the amount of the allowance for credit losses to the difference between amortized cost and fair value. ASU 2016-13 will be effective for the Company as of January 1, 2020. The Company is currently evaluating the potential impact of ASU 2016-13 on the Company’s financial statements. ASU 2016-09, “Compensation - Stock Compensation (Topic 718)—Improvements to Employee Share-Based Payment Accounting.” ASU 2016-09 simplifies the accounting for share-based awards paid to employees. The amended guidance 1) requires excess tax benefits and tax deficiencies on share-based awards payments to employees to be recognized directly to income tax expense or benefit in the Consolidated Statement of Income rather than to capital surplus; 2) requires excess tax benefits to be included as operating activities on the Consolidated Statements of Cash Flows; 3) provides entities with the option of making an accounting policy election to account for forfeitures of share-based payments as they occur instead of estimating the awards expected to be forfeited; and 4) changes the threshold to qualify for equity classification to permit withholdings up to the maximum statutory tax rate in the applicable jurisdiction. In addition, excess tax benefits and tax deficiencies are considered discrete items in the reporting period they occur and are not included in the estimate of an entity’s annual effective tax rate. The Company adopted ASU 2016-09 on January 1, 2017 and elected to recognize forfeitures as they occur. Implementation of ASU 2016-09 will add volatility to tax expense as the Company’s stock price changes. The adoption of ASU 2016-09 did not have a significant impact on the Company’s financial statements. ASU 2016-02, "Leases (Topic 842)." ASU 2016-02 requires that lessees and lessors recognize lease assets and lease liabilities on the balance sheet and disclose key information about leasing arrangements. ASU 2016-02 is effective for public companies for annual periods beginning January 1, 2019, including interim periods within those fiscal years. The Company is currently evaluating the potential impact of ASU 2016-02 on the Company’s financial statements. ASU 2016-01 “Financial Instruments—Overall (Subtopic 825-10) Recognition and Measurement of Financial Assets and Financial Liabilities” ASU 2016-01 addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. ASU 2016-01 (1) requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income; (2) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; (3) eliminates the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities; (4) eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet; (5) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; (6) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments; (7) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements; and (8) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. The amendments in this update affect all entities that hold financial assets or owe financial liabilities. ASU 2016-01 is effective for the Company on January 1, 2018 and is not expected to have a significant impact on the Company’s financial statements. ASU 2014-09, “Revenue from Contracts with Customers (Topic 606).” ASU 2014-09 supersedes the revenue recognition requirements in Revenue Recognition (Topic 605), and most industry-specific guidance throughout the Industry Topics of the Codification. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, the FASB has issued targeted updates to clarify specific implementation issues of ASU 2014-09. These updates include ASU 2016-08 - ASU 2016-10 - ASU 2016-12 - and ASU 2016-20 - s. These amendments do not change the core principles in ASU 2014-09. The Company’s primary sources of revenue are comprised of net interest income on financial assets and liabilities, which are not within the scope of ASU 2014-09. ASU 2014-09 is effective for the Company on January 1, 2018, with a cumulative-effect adjustment, and will not have a significant impact on the financial statements. |

Acquisitions | 2. ACQUISITIONS Acquisitions are an integral part of the Company’s growth strategy. All acquisitions were accounted for using the acquisition method of accounting. Accordingly, the assets and liabilities of the acquired entities were recorded at their fair values at the acquisition date. The excess of the purchase price over the estimated fair value of the net assets for tax-free acquisitions was recorded as goodwill, none of which is deductible for tax purposes. The excess of the purchase price over the estimated fair value of the net assets for taxable acquisitions was also recorded as goodwill, and is deductible for tax purposes. The identified core deposit intangibles for each acquisition are being amortized using a non-pro rata basis over an estimated life of 10 to 15 years. The results of operations for each acquisition have been included in the Company’s consolidated financial results beginning on the respective acquisition date. The measurement period for the Company to determine the fair values of acquired identifiable assets and assumed liabilities will end at the earlier of (1) twelve months from the date of the acquisition or (2) as soon as the Company receives the information it was seeking about facts and circumstances that existed as of the acquisition date or learns that more information is not obtainable. The following acquisitions were completed on the dates indicated: 2016 Acquisition Acquisition of Tradition Bancshares, Inc On January 1, 2016, the Company completed the acquisition of Tradition Bancshares, Inc. (“Tradition”) and its wholly-owned subsidiary Tradition Bank, headquartered in Houston, Texas. Tradition Bank operated 7 banking offices in the Houston, Texas area, including its main office in Bellaire, 3 banking centers in Katy and 1 banking center in The Woodlands. The acquisition was not considered significant to the Company’s financial statements and therefore pro forma financial data and related disclosures are not included. The Company acquired loans and deposits with fair values of $239.7 million and $489.7 million, respectively, at acquisition date. Under the terms of the definitive agreement, Bancshares issued 679,528 shares of its common stock plus $39.0 million in cash for all outstanding shares of Tradition capital stock, for total merger consideration of $71.5 million, based on Bancshares’ closing stock price of $47.86 on December 31, 2015. During 2016, the Company recognized goodwill of $32.0 million, which is calculated as the excess of both the consideration exchanged and liabilities assumed as compared to the fair value of identifiable assets acquired, none of which is expected to be deductible for tax purposes. Additionally, the Company recognized $5.6 million of core deposit intangibles during 2016. Merger-Related Expenses: The Company did not incur merger-related expenses during 2017. During 2016, the Company incurred $670 thousand of pre-tax merger-related expenses attributable to the Tradition acquisition. The merger-related expenses are reflected on the Company’s income statement for the applicable periods and are reported primarily in the categories of salaries and benefits, data processing and travel and development. There were no other merger-related costs incurred during 2016. Acquired Loans Acquired loans were preliminarily recorded at fair value based on a discounted cash flow valuation methodology that considers, among other things, interest rates, projected default rates, loss given default and recovery rates, with no carryover of any existing allowance for credit losses from the acquisition completed during 2016. During the valuation process, the Company identified PCI and Non-PCI loans in the acquired loan portfolios. PCI loan identification considers the following factors: payment history and past due status, debt service coverage, loan grading, collateral values and other factors that may indicate deterioration of credit quality since origination. Non-PCI loan identification considers the following factors: account types, remaining terms, annual interest rates or coupons, current market rates, interest types, past delinquencies, timing of principal and interest payments, loan to value ratios, loss exposures and remaining balances. Accretion of purchased discounts on PCI loans will be based on estimated future cash flows, regardless of contractual maturities. Accretion of purchased discounts on Non-PCI loans will be recognized on a level-yield basis based on contractual maturity of individual loans. PCI Loans. The carrying amount of PCI loans included in the consolidated balance sheets and the related outstanding balances at December 31, 2017 and 2016 are presented in the table below. The outstanding balance represents the total amount owed as of December 31, 2017 and 2016. December 31, 2017 December 31, 2016 (Dollars in thousands) PCI loans: Outstanding balance $ 36,199 $ 51,640 Discount (14,215 ) (24,007 ) Recorded investment $ 21,984 $ 27,633 Changes in the accretable yield for PCI loans for the years ended December 31, 2017 and 2016 were as follows: Year Ended December 31, 2017 2016 (Dollars in thousands) Balance at beginning of period $ 9,778 $ 5,664 Additions — 10,222 Reclassifications from nonaccretable 5,401 11,114 Accretion (7,058 ) (17,222 ) Balance at December 31 $ 8,121 $ 9,778 Income recognition on PCI loans is subject to the Company’s ability to reasonably estimate both the timing and amount of future cash flows. PCI loans for which the Company is accruing interest income are not considered non-performing or impaired. The non-accretable difference represents contractual principal and interest the Company does not expect to collect. Non-PCI Loans. The carrying amount of Non-PCI loans included in the consolidated balance sheets and the related outstanding balances at December 31, 2017 and 2016 are presented in the table below. The outstanding balance represents the total amount owed as of December 31, 2017 and 2016. December 31, 2017 December 31, 2016 (Dollars in thousands) Non-PCI loans: Outstanding balance $ 738,706 $ 1,115,061 Discount (20,533 ) (35,401 ) Recorded investment $ 718,173 $ 1,079,660 Changes in the discount accretion for Non-PCI loans for the years ended December 31, 2017 and 2016 were as follows: Year Ended December 31, 2017 2016 (Dollars in thousands) Balance at beginning of period $ 35,401 $ 54,734 Additions — 3,491 Accretion charge-offs (20 ) (1,076 ) Accretion (14,848 ) (21,748 ) Balance at December 31 $ 20,533 $ 35,401 At December 31, 2017, the Company had $34.7 million of total outstanding discounts on Non-PCI and PCI loans, of which $28.7 million was accretable. |

If any such impairment is determined, a write down is recorded. As of December 31, 2017, there was no impairment recorded on goodwill and core deposit intangibles. Core deposit intangibles are being amortized on a non-pro rata basis over their estimated lives, which the Company believes is between 10 and 15 years. The estimated aggregate future amortization expense for core deposit intangibles remaining as of December 31, 2017 is as follows (dollars in thousands): 2018 $ 5,959 2019 5,051 2020 4,483 2021 4,022 Thereafter 19,327 Total $ 38,842 |

The investment securities portfolio is evaluated for OTTI by segregating the portfolio into two general segments and applying the appropriate OTTI analysis. Investment securities classified as available for sale or held to maturity are evaluated for OTTI under Financial Accounting Standards Board (“FASB”): ASC Topic 320, “Investments—Debt and Equity Securities.” In determining OTTI, management considers many factors, including: (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, (3) whether the market decline was affected by macroeconomic conditions and (4) whether the entity has the intent to sell the debt security or more likely than not will be required to sell the debt security before its anticipated recovery. The assessment of whether an other-than-temporary decline exists involves a high degree of subjectivity and judgment and is based on the information available to management at the time of such determination. When OTTI occurs, the amount of the other-than-temporary impairment recognized in earnings depends on whether an entity intends to sell the security or more likely than not will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss. Management has the ability and intent to hold the securities classified as held-to-maturity until they mature, at which time the Company will receive full value for the securities. Furthermore, as of December 31, 2017, management does not have the intent to sell any of the securities classified as available for sale before a recovery of cost. In addition, management believes it is more likely than not that the Company will not be required to sell any of its investment securities before a recovery of cost. The unrealized losses are largely due to increases in market interest rates over the yields available at the time the underlying securities were purchased. The fair value is expected to recover as the securities approach their maturity date or repricing date or if market yields for such investments decline. Management does not believe any of the securities are impaired due to reasons of credit quality. Accordingly, as of December 31, 2017, management believes any impairment in the Company’s securities is temporary and no impairment loss has been realized in the Company’s consolidated statements of income. Securities with unrealized losses segregated by length of time such securities have been in a continuous loss position were as follows: December 31, 2017 Less than 12 Months More than 12 Months Total Estimated Fair Value Unrealized Losses Estimated Fair Value Unrealized Losses Estimated Fair Value Unrealized Losses (Dollars in thousands) Available for Sale Collateralized mortgage obligations $ 5,753 $ (13 ) $ 2,544 $ (44 ) $ 8,297 $ (57 ) Mortgage-backed securities 42,289 (1,323 ) 2,054 (4 ) 44,343 (1,327 ) Other securities 1,636 (101 ) — — 1,636 (101 ) Total $ 49,678 $ (1,437 ) $ 4,598 $ (48 ) $ 54,276 $ (1,485 ) Held to Maturity U.S. Treasury securities and obligations of U.S. Government agencies $ 4,934 $ (5 ) $ — $ — $ 4,934 $ (5 ) States and political subdivisions 160,392 (773 ) 3,686 (34 ) 164,078 (807 ) Collateralized mortgage obligations 373 (2 ) 100 (3 ) 473 (5 ) Mortgage-backed securities 3,940,075 (34,159 ) 3,883,266 (109,585 ) 7,823,341 (143,744 ) Total $ 4,105,774 $ (34,939 ) $ 3,887,052 $ (109,622 ) $ 7,992,826 $ (144,561 ) December 31, 2016 Less than 12 Months More than 12 Months Total Estimated Fair Value Unrealized Losses Estimated Fair Value Unrealized Losses Estimated Fair Value Unrealized Losses (Dollars in thousands) Available for Sale Collateralized mortgage obligations $ 10,723 $ (119 ) $ — $ — $ 10,723 $ (119 ) Mortgage-backed securities 45,456 (160 ) 2,334 (5 ) 47,790 (165 ) Other securities — — 1,691 (46 ) 1,691 (46 ) Total $ 56,179 $ (279 ) $ 4,025 $ (51 ) $ 60,204 $ (330 ) Held to Maturity U.S. Treasury securities and obligations of U.S. Government agencies — — — — — — States and political subdivisions 115,132 (1,288 ) 5,080 (40 ) 120,212 (1,328 ) Collateralized mortgage obligations 589 (4 ) 44 (1 ) 633 (5 ) Mortgage-backed securities 6,903,919 (195,556 ) 90,293 (3,883 ) 6,994,212 (199,439 ) Total $ 7,019,640 $ (196,848 ) $ 95,417 $ (3,924 ) $ 7,115,057 $ (200,772 ) At December 31, 2017 and 2016 there were 308 securities and 276 securities, respectively, in an unrealized loss position for more than 12 months.

Loans and Allowance for Credit Losses | 6. LOANS AND ALLOWANCE FOR CREDIT LOSSES The loan portfolio consists of various types of loans made principally to borrowers located within the states of Texas and Oklahoma and is categorized by major type as follows: December 31, 2017 2016 (Dollars in thousands) Residential mortgage loans held for sale $ 31,389 $ 26,975 Commercial and industrial 1,479,910 1,539,439 Real estate: Construction, land development and other land loans 1,509,137 1,263,923 1-4 family residential (including home equity) 2,708,471 2,690,856 Commercial real estate (including multi-family residential) 3,315,627 3,162,109 Farmland 502,841 484,588 Agriculture 187,277 187,748 Consumer and other 286,121 266,422 Total loans held for investment 9,989,384 9,595,085 Total $ 10,020,773 $ 9,622,060 Loan Origination/Risk Management. The Company has certain lending policies and procedures in place that are designed to maximize loan income within an acceptable level of risk. Management reviews and approves these policies and procedures on a regular basis. A reporting system supplements the review process by providing management with frequent reports related to loan production, loan quality, concentrations of credit, loan delinquencies and non-performing and potential problem loans. Diversification in the loan portfolio is a means of managing risk associated with fluctuations in economic conditions. Loans to borrowers with aggregate debt relationships over $1.0 million and below $3.5 million are evaluated and acted upon on a daily basis by two of the company-wide loan concurrence officers. Loans to borrowers with aggregate debt relationships above $3.5 million are evaluated and acted upon by an officers’ loan committee that meets weekly. In addition to the officers’ loan committee evaluation, loans to borrowers with aggregate debt relationships from $25.0 million to $50.0 million are evaluated and acted upon by the directors’ loan committee which consists of three directors of the Bank and meets as necessary. Loans to borrowers with aggregate debt relationships over $50.0 million are evaluated and acted upon by the Bank’s Board of Directors either at a regularly scheduled monthly board meeting or by teleconference or written consent. The Company maintains an independent loan review department that reviews and validates the credit risk program on a periodic basis. Results of these reviews are presented to management. The loan review process complements and reinforces the risk identification and assessment decisions made by lenders and credit personnel, as well as the Company’s policies and procedures. (i) Commercial and Industrial Loans . In nearly all cases, the Company’s commercial loans are made in the Company’s market areas and are underwritten on the basis of the borrower’s ability to service the debt from income. As a general practice, the Company takes as collateral a lien on any available real estate, equipment or other assets owned by the borrower and obtains a personal guaranty of the borrower or principal. Working capital loans are primarily collateralized by short-term assets whereas term loans are primarily collateralized by long-term assets. In general, commercial loans involve more credit risk than residential mortgage loans and commercial mortgage loans and, therefore, usually yield a higher return. The increased risk in commercial loans is due to the type of collateral securing these loans as well as the expectation that commercial loans generally will be serviced principally from the operations of the business, and those operations may not be successful. Historical trends have shown these types of loans to have higher delinquencies than mortgage loans. As a result of these additional complexities, variables and risks, commercial loans require more thorough underwriting and servicing than other types of loans. (ii) Commercial Real Estate . The Company makes commercial real estate loans collateralized by owner-occupied and nonowner-occupied real estate to finance the purchase of real estate. The Company’s commercial real estate loans are collateralized by first liens on real estate, typically have variable interest rates (or five year or less fixed rates) and amortize over a 15-to 20-year period. Payments on loans secured by nonowner-occupied properties are often dependent on the successful operation or management of the properties. Accordingly, repayment of these loans may be subject to adverse conditions in the real estate market or the economy to a greater extent than other types of loans. The Company seeks to minimize these risks in a variety of ways, including giving careful consideration to the property’s operating history, future operating projections, current and projected occupancy, location and physical condition in connection with underwriting these loans. The underwriting analysis also includes credit verification, analysis of global cash flow, appraisals and a review of the financial condition of the borrower. At December 31, 2017, approximately 46.0% of the outstanding principal balance of the Company’s commercial real estate loans were secured by owner-occupied properties. (iii) 1-4 Family Residential Loans . The Company’s lending activities also include the origination of 1-4 family residential mortgage loans (including home equity loans) collateralized by owner-occupied residential properties located in the Company’s market areas. The Company offers a variety of mortgage loan portfolio products which generally are amortized over five to 25 years. Loans collateralized by 1-4 family residential real estate generally have been originated in amounts of no more than 89% of appraised value or have mortgage insurance. The Company requires mortgage title insurance and hazard insurance. The Company retains these portfolio loans for its own account rather than selling them into the secondary market. By doing so, the Company incurs interest rate risk as well as the risks associated with nonpayments on such loans. The Company’s Home Loan Center offers a variety of mortgage loan products which are generally amortized over 30 years, including FHA and VA loans. The Company sells the loans originated by the Home Loan Center into the secondary market. (iv) Construction, Land Development and Other Land Loans . The Company makes loans to finance the construction of residential and, to a lesser extent, nonresidential properties. Construction loans generally are collateralized by first liens on real estate and have floating interest rates. The Company conducts periodic inspections, either directly or through an agent, prior to approval of periodic draws on these loans. Underwriting guidelines similar to those described above are also used in the Company’s construction lending activities. Construction loans involve additional risks attributable to the fact that loan funds are advanced upon the security of a project under construction, and the project is of uncertain value prior to its completion. Because of uncertainties inherent in estimating construction costs, the market value of the completed project and the effects of governmental regulation on real property, it can be difficult to accurately evaluate the total funds required to complete a project and the related loan to value ratio. As a result of these uncertainties, construction lending often involves the disbursement of substantial funds with repayment dependent, in part, on the success of the ultimate project rather than the ability of a borrower or guarantor to repay the loan. If the Company is forced to foreclose on a project prior to completion, the Company may not be able to recover all of the unpaid portion of the loan. In addition, the Company may be required to fund additional amounts to complete a project and may have to hold the property for an indeterminate period of time. Although the Company has underwriting procedures designed to identify what it believes to be acceptable levels of risks in construction lending, these procedures may not prevent losses from the risks described above. (v) Agriculture Loans . The Company provides agriculture loans for short-term beef and crop production, including rice, cotton, milo and corn, farm equipment financing and agriculture real estate financing. The Company evaluates agriculture borrowers primarily based on their historical profitability, level of experience in their particular agriculture industry, overall financial capacity and the availability of secondary collateral to withstand economic and natural variations common to the industry. Because agriculture loans present a higher level of risk associated with events caused by nature, the Company routinely makes on-site visits and inspections in order to identify and monitor such risks. (vi) Consumer Loans . Consumer loans made by the Company include direct “A”-credit automobile loans, recreational vehicle loans, boat loans, home improvement loans, personal loans (collateralized and uncollateralized), credit cards and deposit account collateralized loans. The terms of these loans typically range from 12 to 180 months and vary based upon the nature of collateral and size of loan. Generally, consumer loans entail greater risk than do real estate secured loans, particularly in the case of consumer loans that are unsecured or collateralized by rapidly depreciating assets such as automobiles. In such cases, any repossessed collateral for a defaulted consumer loan may not provide an adequate source of repayment for the outstanding loan balance. The remaining deficiency often does not warrant further substantial collection efforts against the borrower beyond obtaining a deficiency judgment. In addition, consumer loan collections are dependent on the borrower’s continuing financial stability, and thus are more likely to be adversely affected by job loss, divorce, illness or personal bankruptcy. Furthermore, the application of various federal and state laws may limit the amount which can be recovered on such loans. The contractual maturity ranges of the Company’s loan portfolio by type of loan and the amount of such loans with predetermined interest rates and floating rates in each maturity range as of December 31, 2017 are summarized in the following table. Contractual maturities are based on contractual amounts outstanding and do not include loan purchase discounts of $34.7 million or loans held for sale of $31.4 million at December 31, 2017: One Year or Less After One Year Through Five Years After Five Years Total (Dollars in thousands) Commercial and industrial $ 515,223 $ 453,988 $ 516,837 $ 1,486,048 Real estate: Construction, land development and other land loans 401,352 267,000 843,226 1,511,578 1-4 family residential (includes home equity) 17,054 115,979 2,581,171 2,714,204 Commercial (includes multi-family residential) 72,072 285,509 2,974,839 3,332,420 Agriculture (includes farmland) 152,082 62,196 478,858 693,136 Consumer and other 78,385 103,458 104,903 286,746 Total $ 1,236,168 $ 1,288,130 $ 7,499,834 $ 10,024,132 Loans with a predetermined interest rate $ 274,095 $ 709,811 $ 3,078,157 $ 4,062,063 Loans with a floating interest rate 962,073 578,319 4,421,677 5,962,069 Total $ 1,236,168 $ 1,288,130 $ 7,499,834 $ 10,024,132 Concentrations of Credit. Most of the Company’s lending activity occurs within the states of Texas and Oklahoma. Commercial real estate loans, 1-4 family residential loans and construction, land development and other land loans make up 75.2% of the Company’s total loan portfolio at December 31, 2017. As of December 31, 2017 and 2016, there were no concentrations of loans related to any single industry in excess of 10% of total loans. Foreign Loans . The Company has U.S. dollar-denominated loans and commitments to borrowers in Mexico. The outstanding balance of these loans and the unfunded amounts available under these commitments was not significant at December 31, 2017 or 2016. Related Party Loans . As of December 31, 2017 and 2016, loans outstanding to directors, officers and their affiliates totaled $2.7 million and $4.5 million, respectively. All transactions between the Company and such related parties are conducted in the ordinary course of business and made on the same terms and conditions as similar transactions with unaffiliated persons. An analysis of activity with respect to these related-party loans is as follows: As of and for the year ended December 31, 2017 2016 (Dollars in thousands) Beginning balance on January 1 $ 4,493 $ 4,063 New loans 175 699 Repayments and reclassified related loans (1,974 ) (269 ) Ending balance $ 2,694 $ 4,493 Nonperforming Assets and Nonaccrual and Past Due Loans. The Company has several procedures in place to assist it in maintaining the overall quality of its loan portfolio. The Company has established underwriting guidelines to be followed by its officers, and the Company also monitors its delinquency levels for any negative or adverse trends. Nevertheless, the Company’s loan portfolio could become subject to increasing pressures from deteriorating borrower credit due to general economic conditions. The Company generally places a loan on nonaccrual status and ceases accruing interest when the payment of principal or interest is delinquent for 90 days, or earlier in some cases, unless the loan is in the process of collection and the underlying collateral fully supports the carrying value of the loan. The Company requires appraisals on loans collateralized by real estate. With respect to potential problem loans, an evaluation of the borrower’s overall financial condition is made to determine the need, if any, for possible writedowns or appropriate additions to the allowance for credit losses.

The Company had $37.5 million in nonperforming assets at December 31, 2017 compared with $48.3 million at December 31, 2016 and $43.5 million at December 31, 2015. Nonperforming assets were 0.37% of total loans and other real estate at December 31, 2017 compared with 0.50% of total loans and other real estate at December 31, 2016 and 0.46% of total loans and other real estate at December 31, 2015. The nonperforming assets consisted of 99 separate credits or other real estate properties at December 31, 2017, compared with 158 at December 31, 2016 and 147 at December 31, 2015. If interest on nonaccrual loans had been accrued under the original loan terms, approximately $2.7 million, $3.2 million, and $3.9 million would have been recorded as income for the years ended December 31, 2017, 2016 and 2015, respectively. Impaired Loans. Loans are considered impaired when, based on current information and events, it is probable the Company will be unable to collect all amounts due in accordance with the original contractual terms of the loan agreement, including scheduled principal and interest payments. Impairment is evaluated in total for smaller-balance loans of a similar nature and on an individual loan basis for other loans. If a loan is impaired, a specific valuation allowance is allocated, if necessary, so that the loan is reported net, at the present value of estimated future cash flows using the loan’s existing rate or at the fair value of collateral if repayment is expected solely from the collateral. Interest payments on impaired loans are typically applied to principal unless collectability of the principal amount is reasonably assured, in which case interest is recognized on a cash basis. Impaired loans, or portions thereof, are charged off when deemed uncollectible. Year-end impaired loans are set forth in the following tables. No interest income was recognized on impaired loans subsequent to their classification as impaired. The average recorded investment presented in the tables below is reported on a year-to-date basis.

As part of the on-going monitoring of the credit quality of the Company’s loan portfolio and methodology for calculating the allowance for credit losses, management assigns and tracks loan grades to be used as credit quality indicators. The following is a general description of the loan grades used: Grade 1 —Credits in this category have risk potential that is virtually nonexistent. These loans may be secured by insured certificates of deposit, insured savings accounts, U.S. Government securities and highly rated municipal bonds. Grade 2 —Credits in this category are of the highest quality. These borrowers represent top-rated companies and individuals with unquestionable financial standing with excellent global cash flow coverage, net worth, liquidity and collateral coverage. Grade 3 —Credits in this category are not immune from risk but are well protected by the collateral and paying capacity of the borrower. These loans may exhibit a minor unfavorable credit factor, but the overall credit is sufficiently strong to minimize the possibility of loss. Grade 4 —Credits in this category are considered to be of acceptable credit quality with moderately greater risk than Grade 3 and receiving closer monitoring. Loans in this category have sources of repayment that remain sufficient to preclude a larger than normal probability of default and secondary sources are likewise currently of sufficient quantity, quality, and liquidity to protect the Company against loss of principal and interest. These borrowers have specific risk factors, but the overall strength of the credit is acceptable based on other mitigating credit and/or collateral factors and can repay the debt in the normal course of business. Grade 5 —Credits in this category constitute an undue and unwarranted credit risk; however, the factors do not rise to a level of substandard. These credits have potential weaknesses and/or declining trends that, if not corrected, could expose the Bank to risk at a future date. These loans are monitored on the Bank’s internally generated watch list and evaluated on a quarterly basis. Grade 6 —Credits in this category are considered “substandard” but “non-impaired” loans in accordance with regulatory guidelines. Loans in this category have well-defined weakness that, if not corrected, could make default of principal and interest possible. Loans in this category are still accruing interest and may be dependent upon secondary sources of repayment and/or collateral liquidation. Grade 7 —Credits in this category are deemed “substandard” and “impaired” pursuant to regulatory guidelines. As such, the Bank has determined that it is probable that less than 100% of the contractual principal and interest will be collected. These loans are individually evaluated for a specific reserve and will typically have the accrual of interest stopped. Grade 8 —Credits in this category include “doubtful” loans in accordance with regulatory guidance. Such loans are no longer accruing interest and factors indicate a loss is imminent. These loans are also deemed “impaired.” While a specific reserve may be in place while the loan and collateral is being evaluated these loans are typically charged down to an amount the Bank estimates is collectible. Grade 9 —Credits in this category are deemed a “loss” in accordance with regulatory guidelines and have been charged off or charged down. The Bank may continue collection efforts and may have partial recovery in the future. The following table presents risk grades and PCI loans by category of loan at December 31, 2017. Impaired loans include loans in risk grades 7, 8 and 9, as well as any PCI loan that has a specific reserve allocated to it.

(2) Of the total PCI loans, $2.7 million were classified as substandard at December 31, 2016, which includes $31 thousand with specific reserves allocated to them. Allowance for Credit Losses. The allowance for credit losses is a valuation established through charges to earnings in the form of a provision for credit losses. Management has established an allowance for credit losses which it believes is adequate as of December 31, 2017 for estimated losses in the Company’s loan portfolio. The amount of the allowance for credit losses is affected by the following: (1) charge-offs of loans that occur when loans are deemed uncollectible and decrease the allowance, (2) recoveries on loans previously charged off that increase the allowance and (3) provisions for credit losses charged to earnings that increase the allowance. Based on an evaluation of the loan portfolio and consideration of the factors listed below, management presents a quarterly review of the allowance for credit losses to the Bank’s Board of Directors, indicating any change in the allowance since the last review and any recommendations as to adjustments in the allowance. Although management believes it uses the best information available to make determinations with respect to the allowance for credit losses, future adjustments may be necessary if economic conditions or the borrower’s performance differ from the assumptions used in making the initial determinations. The Company’s allowance for credit losses consists of two components: (1) a specific valuation allowance based on probable losses on specifically identified loans and (2) a general valuation allowance based on historical loan loss experience, general economic conditions and other qualitative risk factors both internal and external to the Company. In setting the specific valuation allowance, the Company follows a loan review program to evaluate the credit risk in the total loan portfolio and assigns risk grades to each loan. Through this loan review process, the Company maintains an internal list of impaired loans which, along with the delinquency list of loans, helps management assess the overall quality of the loan portfolio and the adequacy of the allowance for credit losses. All loans that have been identified as impaired are reviewed on a quarterly basis in order to determine whether a specific reserve is required. For certain impaired loans, the Company allocates a specific loan loss reserve primarily based on the value of the collateral securing the impaired loan in accordance with ASC Topic 310-10, “Receivables.” In connection with this review of the loan portfolio, the Company considers risk elements attributable to particular loan types or categories in assessing the quality of individual loans. Some of the risk elements include: • for 1-4 family residential mortgage loans, the borrower’s ability to repay the loan, including a consideration of the debt to income ratio and employment and income stability, the loan to value ratio, and the age, condition and marketability of collateral; • for commercial real estate loans and multifamily residential loans, the debt service coverage ratio (income from the property in excess of operating expenses compared to loan payment requirements), operating results of the owner in the case of owner-occupied properties, the loan to value ratio, the age and condition of the collateral and the volatility of income, property value and future operating results typical of properties of that type; • for construction, land development and other land loans, the perceived feasibility of the project including the ability to sell developed lots or improvements constructed for resale or the ability to lease property constructed for lease, the quality and nature of contracts for presale or prelease, if any, experience and ability of the developer and loan to value ratio; • for commercial and industrial loans, the operating results of the commercial, industrial or professional enterprise, the borrower’s business, professional and financial ability and expertise, the specific risks and volatility of income and operating results typical for businesses in that category and the value, nature and marketability of collateral; • for agricultural real estate loans, the experience and financial capability of the borrower, projected debt service coverage of the operations of the borrower and loan to value ratio; and • for non-real estate agricultural loans, the operating results, experience and financial capability of the borrower, historical and expected market conditions and the value, nature and marketability of collateral. In addition, for each category, the Company considers secondary sources of income and the financial strength and credit history of the borrower and any guarantors. In determining the amount of the general valuation allowance, management considers factors such as historical loan loss experience, concentration risk of specific loan types, the volume, growth and composition of the Company’s loan portfolio, current economic conditions that may affect the borrower’s ability to pay and the value of collateral, the evaluation of the Company’s loan portfolio through its internal loan review process, general economic conditions and other qualitative risk factors both internal and external to the Company and other relevant factors in accordance with ASC Topic 450, “ Contingencies.” A change in the allowance for credit losses can be attributable to several factors, most notably (1) specific reserves identified for impaired loans, (2) historical credit loss information, (3) changes in environmental factors and (4) growth in the balance of legacy loans and the renewal or substantial modification of acquired loans (Non-PCI and PCI |

Fair Value Disclosures [Abstract] | |
Fair Value | 7. FAIR VALUE The Company uses fair value measurements to record fair value adjustments to certain assets and to determine fair value disclosures. Fair values represent the estimated price that would be received from selling an asset or paid to transfer a liability, otherwise known as an “exit price.” Securities available for sale are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may be required to record at fair value other assets on a nonrecurring basis. These nonrecurring fair value adjustments typically involve application of lower-of-cost-or-market accounting or write downs of individual assets. ASC Topic 820, “Fair Value Measurements and Disclosures” Fair Value Hierarchy The Company groups financial assets and financial liabilities measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are: • Level 1—Quoted prices in active markets for identical assets or liabilities. • Level 2—Other significant observable inputs (including quoted prices in active markets for similar assets or liabilities) or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. In estimating fair value, the Company utilizes valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. Such valuation techniques are consistently applied. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. The fair value disclosures below represent the Company’s estimates based on relevant market information and information about the financial instruments. Fair value estimates are based on judgments regarding current economic conditions, risk characteristics of the various instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in the above methodologies and assumptions could significantly affect the estimates. The following tables present fair values for assets measured at fair value on a recurring basis: As of December 31, 2017 Level 1 Level 2 Level 3 Total (Dollars in thousands) Available for sale securities: States and political subdivisions $ — $ 1,820 $ — $ 1,820 Collateralized mortgage obligations — 100,061 — 100,061 Mortgage-backed securities — 103,489 — 103,489 Other securities 12,500 — — 12,500 As of December 31, 2016 Level 1 Level 2 Level 3 Total (Dollars in thousands) Available for sale securities: States and political subdivisions $ — $ 1,920 $ — $ 1,920 Collateralized mortgage obligations — 120,599 — 120,599 Mortgage-backed securities — 85,863 — 85,863 Other securities 12,794 — — 12,794 Certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). These instruments include other real estate owned, repossessed assets, held to maturity debt securities, loans held for sale, and impaired loans. For the year ended December 31, 2017, the Company had additions to other real estate owned of $1.6 million, of which $923 thousand were outstanding as of December 31, 2017. For the year ended December 31, 2017, the Company had additions to impaired loans of $20.9 million, of which $17.6 million were outstanding as of December 31, 2017. The remaining financial assets and liabilities measured at fair value on a non-recurring basis that were recorded in 2017 and remained outstanding at December 31, 2017 were not significant. The following tables summarize the carrying values and estimated fair values of certain financial instruments not recorded at fair value on a recurring basis: As of December 31, 2017 Carrying Estimated Fair Value Amount Level 1 Level 2 Level 3 Total (Dollars in thousands) Assets Cash and due from banks $ 391,616 $ 391,616 $ — $ — $ 391,616 Federal funds sold 697 697 — — 697 Held to maturity securities 9,454,246 — 9,323,482 — 9,323,482 Loans held for sale 31,389 — 31,389 — 31,389 Loans held for investment, net of allowance 9,905,343 — — 9,923,556 9,923,556 Other real estate owned 11,152 — 11,152 — 11,152 Liabilities Deposits: Noninterest-bearing $ 5,623,322 $ — $ 5,623,322 $ — $ 5,623,322 Interest-bearing 12,198,138 — 12,173,164 — 12,173,164 Other borrowings 505,223 — 505,390 — 505,390 Securities sold under repurchase agreements 324,154 — 324,118 — 324,118 As of December 31, 2016 Carrying Estimated Fair Value Amount Level 1 Level 2 Level 3 Total (Dollars in thousands) Assets Cash and due from banks $ 436,203 $ 436,203 $ — $ — $ 436,203 Federal funds sold 1,178 1,178 — — 1,178 Held to maturity securities 9,504,910 — 9,339,455 — 9,339,455 Loans held for sale 26,975 — 26,975 — 26,975 Loans held for investment, net of allowance 9,509,759 — — 9,533,310 9,533,310 Other real estate owned 15,463 — 15,463 — 15,463 Liabilities Deposits: Noninterest-bearing $ 5,190,973 $ — $ 5,190,973 $ — $ 5,190,973 Interest-bearing 12,116,329 — 12,121,157 — 12,121,157 Other borrowings 990,781 — 991,181 — 991,181 Securities sold under repurchase agreements 320,430 — 320,428 — 320,428 Entities may choose to measure eligible financial instruments at fair value at specified election dates. The fair value measurement option (1) may be applied instrument by instrument, with certain exceptions, (2) is generally irrevocable and (3) is applied only to entire instruments and not to portions of instruments. Unrealized gains and losses on items for which the fair value measurement option has been elected must be reported in earnings at each subsequent reporting date. During the reported periods, the Company had no financial instruments measured at fair value under the fair value measurement option. The fair value estimates presented herein are based on pertinent information available to management as of the dates indicated. Although management is not aware of any factors that would significantly affect the estimated fair value amounts, such amounts have not been comprehensively revalued for purposes of these financial statements since those dates and, therefore, current estimates of fair value may differ significantly from the amounts presented herein. The following is a description of valuation methodologies used for assets and liabilities recorded at fair value, non-financial assets and non-financial liabilities, and for estimating fair value for financial instruments not recorded at fair value: Cash and due from banks —For these short-term instruments, the carrying amount is a reasonable estimate of fair value. The Company classifies the estimated fair value of these instruments as Level 1. Federal funds sold —For these short-term instruments, the carrying amount is a reasonable estimate of fair value. The Company classifies the estimated fair value of these instruments as Level 1. Securities —Fair value measurements based upon quoted prices are considered Level 1 inputs. Level 1 securities consist of U.S. Treasury securities and certain equity securities which are included in the available for sale portfolio. For all other available for sale and held to maturity securities, if quoted prices are not available, fair values are measured using Level 2 inputs. For these securities, the Company generally obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. The Company reviews the prices supplied by the independent pricing service, as well as their underlying pricing methodologies, for reasonableness. Securities available for sale are recorded at fair value on a recurring basis. Loans held for sale —Loans held for sale are carried at the lower of cost or estimated fair value. Fair value for consumer mortgages held for sale is based on commitments on hand from investors or prevailing market prices. As such, the Company classifies loans subjected to nonrecurring fair value adjustments as Level 2. Loans held for investment —The Company does not record loans at fair value on a recurring basis. As such, valuation techniques discussed herein for loans are primarily for estimating fair value disclosures. However, from time to time, the Company records nonrecurring fair value adjustments to impaired loans to reflect (1) partial write downs that are based on the observable market price or current appraised value of the collateral, or (2) the full charge-off of the loan carrying value. Where appraisals are not available, estimated cash flows are discounted using a rate commensurate with the credit risk associated with those cash flows. Assumptions regarding credit risk, cash flows and discount rates are judgmentally determined using available market information and specific borrower information. The estimated fair value approximates carrying value for variable-rate loans that reprice frequently and with no significant change in credit risk. The fair value of fixed-rate loans and variable-rate loans which reprice on an infrequent basis is estimated by discounting future cash flows using the current interest rates at which similar loans with similar terms would be made to borrowers of similar credit quality. An overall valuation adjustment is made for specific credit risks as well as general portfolio credit risk. The Company classifies the estimated fair value of loans held for investment as Level 3. Other real estate owned —Other real estate owned is primarily foreclosed properties securing residential loans and commercial real estate. Foreclosed assets are adjusted to fair value less estimated costs to sell upon transfer of the loans to other real estate owned. Subsequently, these assets are carried at the lower of carrying value or fair value less estimated costs to sell. Other real estate carried at fair value based on an observable market price or a current appraised value is classified by the Company as Level 2. When management determines that the fair value of other real estate requires additional adjustments, either as a result of a non-current appraisal or when there is no observable market price, the Company classifies the other real estate as Level 3. Deposits —The fair value of demand deposits, savings accounts and certain money market deposits is the amount payable on demand at the reporting date. The fair value of fixed-maturity certificates of deposit is estimated using the rates currently offered for deposits of similar remaining maturities. Deposits fair value measurements utilize Level 2 inputs. Other borrowings —Rates currently available to the Company for debt with similar terms and remaining maturities are used to estimate the fair value of other borrowings using a discounted cash flows methodology and are measured utilizing Level 2 inputs. Securities sold under repurchase agreements —The fair value of securities sold under repurchase agreements is the amount payable on demand at the reporting date and are measured utilizing Level 2 inputs. Off-balance sheet financial instruments —The fair value of commitments to extend credit and standby letters of credit is estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreement and the present creditworthiness of the counterparties. The Company has reviewed the unfunded portion of commitments to extend credit as well as standby and other letters of credit, and has determined that the fair value of such financial instruments is not material. The Company classifies the estimated fair value of credit-related financial instruments as Level 3. |

OTHER BORROWINGS AND SECURITIES SOLD UNDER REPURCHASE AGREEMENTS The Company utilizes borrowings to supplement deposits to fund its lending and investment activities. Borrowings consist of funds from the Federal Home Loan Bank (“FHLB”) and securities sold under repurchase agreements. The following table presents the Company’s borrowings at December 31, 2017 and 2016: December 31, 2017 2016 (Dollars in thousands) FHLB advances $ 500,000 $ 985,000 FHLB long-term notes payable 5,223 5,781 Total other borrowings 505,223 990,781 Securities sold under repurchase agreements 324,154 320,430 Total $ 829,377 $ 1,311,211 FHLB advances and long-term notes payable —The Company has an available line of credit with the FHLB of Dallas, which allows the Company to borrow on a collateralized basis. FHLB advances are considered short-term borrowings and used to manage liquidity as needed. Maturing advances are replaced by drawing on available cash, making additional borrowings or through increased customer deposits. At December 31, 2017, the Company had total funds of $5.77 billion available under this agreement, of which a total amount of $505.2 million was outstanding at December 31, 2017. FHLB advances were $500.0 million at December 31, 2017, with a weighted average interest rate of 1.21%. Long-term notes payable were $5.2 million at December 31, 2017, with a weighted average interest rate of 5.70%. The maturity dates on the FHLB notes payable range from the years 2018 to 2027 and have interest rates ranging from 4.51% to 6.10%. Securities sold under repurchase agreements with Company customers —At December 31, 2017, the Company had $324.2 million in securities sold under repurchase agreements compared with $320.4 million at December 31, 2016, with average rates paid of 0.39% and 0.29% for the years ended December 31, 2017 and 2016, respectively.

As a result of the new law, which is more fully discussed below, the Company recognized a net tax expense totaling $1.4 million, as presented in the table above. During 2017, the Company adopted a new accounting standard that requires the income tax effects associated with stock-based compensation to be recognized as a component of income tax expense. The Company recognized net tax benefits related to stock-based compensation totaling $442 thousand in 2017, as presented in the table above. See Note 1 - Significant Accounting Policies for additional information related to the accounting for the income tax effects of stock-based compensation. Year-end deferred taxes are presented in the table below. As a result of the Tax Cuts and Jobs Act enacted on December 22, 2017, deferred taxes as of December 31, 2017 are based on the newly enacted U.S. statutory federal corporate income tax rate of 21%. Deferred taxes as of December 31, 2016 are based on the previously enacted U.S. statutory federal corporate income tax rate of 35%. December 31, 2017 2016 (Dollars in thousands) Deferred tax assets: Loan purchase discounts $ 7,297 $ 20,793 Allowance for credit losses 16,897 28,745 Accrued liabilities 1,476 2,985 Restricted stock 5,640 10,088 Deferred compensation 2,433 4,100 Certificates of Deposit 22 113 Net operating losses 129 424 ORE write-downs 710 — Investments in partnerships 106 213 Unrealized loss on available for sale securities 30 — Other 19 162 Total deferred tax assets 34,759 67,623 Deferred tax liabilities: Goodwill and core deposit intangibles (22,664 ) (35,813 ) Bank premises and equipment (7,252 ) (13,504 ) Securities (494 ) (1,517 ) Unrealized gain on available for sale securities — (760 ) Prepaid expenses (566 ) (1,295 ) Deferred loan fees and costs (4,091 ) (5,300 ) Total deferred tax liabilities (35,067 ) (58,189 ) Net deferred tax (liabilities) assets $ (308 ) $ 9,434 The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. Based upon the level of historical taxable income and estimates of future taxable income over the periods for which the deferred tax assets are deductible, management believes it is more likely than not the Company will realize the benefits of these deductible differences at December 31, 2017. Benefits from tax positions are recognized in the financial statements only when it is more likely than not that the tax position will be sustained upon examination by the appropriate taxing authority that would have full knowledge of all relevant information. A tax position that meets the more-likely-than-not recognition threshold is measured at the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. Tax positions that previously failed to meet the more-likely-than-not recognition threshold are recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not recognition threshold are derecognized in the first subsequent financial reporting period in which that threshold is no longer met. The Company had no tax positions at December 31, 2017 or December 31, 2016 that did not meet the more-likely-than not recognition threshold. ASC Topic 740 “Income Taxes” Tax Cuts and Jobs Act. The Tax Cuts and Jobs Act was enacted on December 22, 2017. Among other things, the new law (i) establishes a new, flat federal statutory corporate income tax rate of 21%, (ii) eliminates the corporate alternative minimum tax and allows the use of any such carryforwards to offset regular tax liability for any taxable year, (iii) limits the deduction for net interest expense incurred by U.S. corporations, (iv) allows businesses to immediately expense, for tax purposes, the cost of new investments in certain qualified depreciable assets, (v) eliminates or reduces certain deductions related to meals and entertainment expenses, (vi) modifies the limitation on excessive employee remuneration to eliminate the exception for performance-based compensation and clarifies the definition of a covered employee and (vii) limits the deductibility of deposit insurance premiums. The Tax Cuts and Jobs Act also significantly changes U.S. tax law related to foreign operations, however, such changes do not currently impact the Company. As stated above, as a result of the enactment of the Tax Cuts and Jobs Act on December 22, 2017, the Company remeasured its deferred tax assets and liabilities based upon the newly enacted U.S. statutory federal corporate income tax rate of 21%, which is the tax rate at which these assets and liabilities are expected to reverse in the future. The Company is still analyzing certain aspects of the new law and refining its calculations, which could affect the measurement of these deferred tax assets and liabilities or give rise to new deferred tax amounts. The Company recognized a one-time non-cash income tax expense related to the remeasurement of its deferred tax assets and liabilities totaling $1.4 million during the year ended December 31, 2017. |

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract] | |
Stock Incentive Programs | 12. STOCK INCENTIVE PROGRAMS At December 31, 2017, the Company had two stock-based employee compensation plans with awards outstanding. One of these plans has expired and therefore no additional awards may be issued under that plan. The Company accounts for stock-based employee compensation plans using the fair value-based method of accounting. The Company recognized stock-based compensation expense of $6.9 million, $9.5 million and $11.1 million for the years ended December 31, 2017, 2016 and 2015, respectively. There was approximately $2.4 million, $3.3 million and $3.9 million of income tax benefit recorded for the stock-based compensation expense for the same periods, respectively. In December 2004, Bancshares’ Board of Directors established the Prosperity Bancshares, Inc. 2004 Stock Incentive Plan (the “2004 Plan”), which was approved by Bancshares’ shareholders on February 23, 2005. The 2004 Plan authorized the issuance of up to 1,250,000 shares of common stock upon the exercise of options granted under the 2004 Plan or upon the grant or exercise, as the case may be, of other awards granted under the 2004 Plan. The 2004 Plan provided for grants of incentive and nonqualified stock options to employees and nonqualified stock options to directors who are not employees. The 2004 Plan also provided for grants of shares of restricted stock, stock appreciation rights, phantom stock awards and performance awards on substantially similar terms. A total of 191,625 options and 793,218 shares of restricted stock have been granted under the 2004 Plan as of December 31, 2017. No options granted under the 2004 Plan were outstanding at December 31, 2017. The 2004 Plan has expired and therefore no additional shares may be issued under the 2004 Plan. On February 22, 2012, Bancshares’ Board of Directors adopted the Prosperity Bancshares, Inc. 2012 Stock Incentive Plan (the “2012 Plan”), which was approved by Bancshares’ shareholders on April 17, 2012. The 2012 Plan authorizes the issuance of up to 1,250,000 shares of common stock upon the exercise of options granted under the 2012 Plan or pursuant to the grant or exercise, as the case may be, of other awards granted under the 2012 Plan, including restricted stock, stock appreciation rights, phantom stock awards and performance awards. A total of 359,133 shares of restricted stock have been granted under the 2012 Plan as of December 31, 2017. Stock Options Stock options are issued at the current market price on the date of the grant, subject to a pre-determined vesting period with a contractual term of 10 years. Options assumed in connection with acquisitions have contractual terms as established in the original option grant agreements entered into prior to acquisition. The fair value of stock options granted is estimated at the date of grant using the Black-Scholes option-pricing model. The Black-Scholes pricing model utilizes certain assumptions including expected life of the option, risk free interest rate, volatility and dividend yield. Stock-based compensation expense is recognized ratably over the requisite service period for all awards. There were no options issued for the years ended December 31, 2017, 2016 and 2015 and the Company had no options outstanding at December 31, 2017. A summary of changes in outstanding vested and unvested options during the three-year period ended December 31, 2017 is set forth below: Number of Options Weighted Average Exercise Price Weighted Average Contractual Term Aggregate Intrinsic Value (In thousands) (In years) (In thousands) Options outstanding, December 31, 2014 53 $ 27.68 2.69 $ 1,473 Options granted — — Options forfeited (15 ) 27.15 Options exercised (9 ) 29.92 Options outstanding, December 31, 2015 29 $ 32.14 2.60 453 Options granted — — Options forfeited — — Options exercised (24 ) 32.65 Options outstanding, December 31, 2016 5 $ 29.69 2.75 210 Options granted — — Options forfeited — — Options exercised (5 ) 29.69 Options outstanding, December 31, 2017 — $ — — $ — Shares vested or expected to vest, December 31, 2017 — $ — — $ — Shares exercisable, December 31, 2017 — $ — — $ — The total intrinsic value of the options exercised during the years ended December 31, 2017 and 2016 was $202 thousand and $931 thousand, respectively. No options vested during the year ended December 31, 2017, as all options vested prior to 2017. There were no unvested options forfeited during the years ended December 31, 2017 and 2016. The Company received $148 thousand, $778 thousand and $290 thousand in cash from the exercise of stock options during the years ended December 31, 2017, 2016 and 2015, respectively. There was no tax benefit realized from exercises of the stock-based compensation arrangements during the years ended December 31, 2017, 2016 and 2015. Restricted Stock The Company has granted shares of restricted stock pursuant to the 2004 and 2012 Plans. These shares of restricted stock generally vest over a period of one to five years. The Company accounts for restricted stock grants by recording the fair value of the grant as compensation expense over the vesting period. Compensation expense related to restricted stock was $6.9 million, $9.5 million and $11.1 million for the years ended December 31, 2017, 2016 and 2015, respectively. A summary of the status of nonvested shares of restricted stock as of December 31, 2017, and changes during the year then ended is as follows: Number of Shares Weighted Average Grant Date Fair Value (Shares in thousands) Nonvested share awards outstanding, December 31, 2016 503 $ 45.35 Share awards granted 21 66.52 Unvested share awards forfeited (26 ) 60.99 Share awards vested (80 ) 53.90 Nonvested share awards outstanding, December 31, 2017 418 $ 56.53 The total fair value of restricted stock awards that fully vested during the year ended December 31, 2017 was $5.4 million. As of December 31, 2017, there was $28.8 million of total unrecognized compensation expense related to stock-based compensation arrangements. That cost is expected to be recognized over a weighted average period of 1.94 years. |

Off-Balance Sheet Arrangements, Commitments and Contingencies | 15. OFF-BALANCE SHEET ARRANGEMENTS, COMMITMENTS AND CONTINGENCIES The following table summarizes the Company’s contractual obligations and other commitments to make future payments as of December 31, 2017 (other than deposit obligations and securities sold under repurchase agreements). The Company’s future cash payments associated with its contractual obligations pursuant to its FHLB notes payable and operating leases as of December 31, 2017 are summarized below. The future interest payments were calculated using the current rate in effect at December 31, 2017. Payments for FHLB notes payable include interest of $364 thousand that will be paid over the future periods. Payments related to leases are based on actual payments specified in underlying contracts. 1 year or less More than 1 year but less than 3 years 3 years or more but less than 5 years 5 years or more Total (Dollars in thousands) Federal Home Loan Bank notes payable $ 504,330 $ 980 $ 125 $ 152 $ 505,587 Operating leases 5,019 7,781 4,106 6,256 23,162 Total $ 509,349 $ 8,761 $ 4,231 $ 6,408 $ 528,749 Off-Balance Sheet Items In the normal course of business, the Company enters into various transactions, which, in accordance with GAAP, are not included in its consolidated balance sheets. The Company enters into these transactions to meet the financing needs of its customers. These transactions include commitments to extend credit and standby letters of credit, which involve, to varying degrees, elements of credit risk and interest rate risk in excess of the amounts recognized in the consolidated balance sheets. The Company’s commitments associated with outstanding standby letters of credit and commitments to extend credit expiring by period as of December 31, 2017 are summarized below. 1 year or less More than 1 year but less than 3 years 3 years or more but less than 5 years 5 years or more Total (Dollars in thousands) Standby letters of credit $ 64,799 $ 7,133 $ 488 $ — $ 72,420 Commitments to extend credit 908,606 394,752 211,191 864,275 2,378,824 Total $ 973,405 $ 401,885 $ 211,679 $ 864,275 $ 2,451,244 Standby Letters of Credit. Standby letters of credit are written conditional commitments issued by the Company to guarantee the payment by or performance of a customer to a third party. In the event the customer does not perform in accordance with the terms of the agreement with the third party, the Company would be required to fund the commitment. The maximum potential amount of future payments the Company could be required to make is represented by the contractual amount of the commitment. If the commitment is funded, the Company would be entitled to seek recovery from the customer. The Company’s policies generally require that standby letter of credit arrangements contain security and debt covenants similar to those contained in loan agreements. Commitments to Extend Credit. The Company enters into contractual commitments to extend credit, normally with fixed expiration dates or termination clauses, at specified rates and for specific purposes. Substantially all of the Company’s commitments to extend credit are contingent upon customers maintaining specific credit standards at the time of loan funding. The Company minimizes its exposure to loss under these commitments by subjecting them to credit approval and monitoring procedures. Management assesses the credit risk associated with certain commitments to extend credit in determining the level of the allowance for credit losses. Since many of the commitments are expected to expire without being fully drawn upon, the total commitment amounts disclosed above do not necessarily represent future cash funding requirements. At December 31, 2017, $225.2 million of commitments to extend credit and standby letters of credit have fixed rates ranging from 1.6% to 21.0%. The Company evaluates customer creditworthiness on a case-by-case basis. The amount of collateral obtained, if considered necessary by the Company upon extension of credit, is based on management’s credit evaluation of the customer. Leases —The following table presents a summary of non-cancelable future operating lease commitments as of December 31, 2017 (dollars in thousands): 2018 $ 5,019 2019 4,345 2020 3,436 2021 2,353 2022 1,753 Thereafter 6,256 $ 23,162 It is expected that in the normal course of business, expiring leases will be renewed or replaced by leases on other property or equipment. Rent expense under all noncancelable operating lease obligations aggregated approximately $6.7 million for the year ended December 31, 2017, $7.4 million for the year ended December 31, 2016 and $7.4 million for the year ended December 31, 2015. Litigation —The Company and the Bank are defendants, from time to time, in legal actions arising from transactions conducted in the ordinary course of business. After consultations with legal counsel, the Company and the Bank believe that the ultimate liability, if any, arising from such actions will not have a material adverse effect on their financial statements. |

Banking And Thrift [Abstract] | |
Regulatory Matters | 17. REGULATORY MATTERS The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Any institution that fails to meet its minimum capital requirements is subject to actions by regulators that could have a direct material effect on the Company’s financial statements. Under the capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines based on the Bank’s assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The Company’s and the Bank’s capital amounts and the Bank’s classification under the regulatory framework for prompt corrective action are also subject to qualitative judgments by the regulators about the components, risk weightings and other factors. The Basel III Capital Rules adopted by the federal regulatory authorities in 2013 substantially revised the risk-based capital requirements applicable to the Company and the Bank. The Basel III Capital Rules became effective for the Company and the Bank on January 1, 2015, subject to a phase-in period for certain provisions. Among other things, the Basel III Capital Rules introduced a new capital measure called “Common Equity Tier 1” (“CET1”), which is a comparison of the sum of certain equity capital components to total risk-weighted assets, and revised the risk-weighting approach of the capital ratios with a more risk-sensitive approach that expanded the risk-weighting categories from the previous Basel I derived categories to a much larger and more risk-sensitive number of categories, depending on the nature of the assets. To meet the capital adequacy requirements, the Company and the Bank must maintain minimum capital amounts and ratios of CET1, Tier 1 and Total capital to risk weighted assets, and of Tier 1 capital to adjusted quarterly average assets as defined in the regulations. As of December 31, 2017, the Company and the Bank met all capital adequacy requirements to which they were subject. The Basel III Capital Rules require a “capital conservation buffer,” composed entirely of CET1, in addition to the minimum risk-weighted asset capital ratios. The implementation of the capital conservation buffer began on January 1, 2016 at the 0.625% level and is being phased in over a four-year period (increasing by that amount on each subsequent January 1, until it reaches 2.5% on January 1, 2019). The required phase-in buffer during 2017 was 1.25%. The CET1, Tier 1 and total capital ratios are calculated by dividing the respective capital amounts by risk weighted assets. Risk weighted assets include total assets, excluding goodwill and other intangible assets, allocated by risk weight category, and certain off-balance-sheet items. The leverage ratio is calculated by dividing Tier 1 capital by adjusted quarterly average total assets, excluding goodwill and other intangible assets. As of December 31, 2017, the most recent notification from the FDIC categorized the Bank as “well capitalized” under the regulatory framework for prompt corrective action. There have been no conditions or events since that notification which management believes have changed the Bank’s category. To be categorized as well capitalized the Bank must maintain minimum CET1 risk-based, Tier 1 risk-based, total risk-based and Tier 1 leverage ratios as set forth in the table below. The following is a summary of the Company’s and the Bank’s capital ratios at December 31, 2017 and 2016: Actual Minimum Required For Capital Adequacy Purposes Minimum Required Plus Capital Conservation Buffer for 2017 To Be Categorized As Well Capitalized Under Prompt Corrective Action Provisions Amount Ratio Amount Ratio Amount Ratio Amount Ratio (Dollars in thousands) CONSOLIDATED: As of December 31, 2017 (1) CET1 Capital (to Risk Weighted Assets) $ 1,898,009 15.08 % $ 566,568 4.50 % $ 723,948 5.750 % N/A N/A Tier 1 Capital (to Risk Weighted Assets) 1,898,009 15.08 % 755,424 6.00 % 912,805 7.250 % N/A N/A Total Capital (to Risk Weighted Assets) 1,982,051 15.74 % 1,007,233 8.00 % 1,164,613 9.250 % N/A N/A Tier 1 Capital (to Average Tangible Assets) 1,898,009 9.31 % 815,633 4.00 % 815,633 4.000 % N/A N/A As of December 31, 2016 (1) CET1 Capital (to Risk Weighted Assets) $ 1,721,055 14.48 % $ 534,852 4.50 % $ 609,136 5.125 % N/A N/A Tier 1 Capital (to Risk Weighted Assets) 1,721,055 14.48 % 713,135 6.00 % 787,420 6.625 % N/A N/A Total Capital (to Risk Weighted Assets) 1,806,382 15.20 % 950,847 8.00 % 1,025,132 8.625 % N/A N/A Tier 1 Capital (to Average Tangible Assets) 1,721,055 8.68 % 793,457 4.00 % 793,457 4.000 % N/A N/A BANK ONLY: As of December 31, 2017 (1) CET1 Capital (to Risk Weighted Assets) $ 1,884,811 14.98 % $ 566,260 4.50 % $ 723,554 5.750 % $ 817,931 6.50 % Tier 1 Capital (to Risk Weighted Assets) 1,884,811 14.98 % 755,013 6.00 % 912,308 7.250 % 1,006,684 8.00 % Total Capital (to Risk Weighted Assets) 1,968,852 15.65 % 1,006,684 8.00 % 1,163,979 9.250 % 1,258,355 10.00 % Tier 1 Capital (to Average Tangible Assets) 1,884,811 9.25 % 815,199 4.00 % 815,199 4.000 % 1,018,999 5.00 % As of December 31, 2016 (1) CET1 Capital (to Risk Weighted Assets) $ 1,704,620 14.35 % $ 534,392 4.50 % $ 608,613 5.125 % $ 771,899 6.50 % Tier 1 Capital to Risk Weighted Assets) 1,704,620 14.35 % 712,522 6.00 % 786,743 6.625 % 950,030 8.00 % Total Capital (to Risk Weighted Assets) 1,789,946 15.07 % 950,030 8.00 % 1,024,251 8.625 % 1,187,537 10.00 % Tier 1 Capital (to Average Tangible Assets) 1,704,620 8.60 % 793,006 4.00 % 793,006 4.000 % 991,257 5.00 % (1) Calculated pursuant to the phase-in provisions of the Basel III Capital Rules.

Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
Nature of Operations | Nature of Operations —Prosperity Bancshares, Inc . ® ® As of December 31, 2017, the Bank operated 242 full-service banking locations; with 65 in the Houston area, including The Woodlands; 29 in the South Texas area including Corpus Christi and Victoria; 33 in the Dallas/Fort Worth, Texas area; 22 in the East Texas area; 29 in the Central Texas area, including Austin and San Antonio; 34 in the West Texas area including Lubbock, Midland-Odessa and Abilene; 16 in the Bryan/College Station area; 6 in the Central Oklahoma area; and 8 in the Tulsa, Oklahoma area. |
Summary of Significant Accounting and Reporting Policies | Summary of Significant Accounting and Reporting Policies — The accounting and reporting policies of the Company conform to generally accepted accounting principles (“GAAP”) and the prevailing practices within the financial services industry. A summary of significant accounting and reporting policies are as follows: |
Basis of Presentation | Basis of Presentation — The consolidated financial statements include the accounts of Bancshares and its subsidiaries. Intercompany transactions have been eliminated in consolidation. Operations are managed and financial performance is evaluated on a company-wide basis. Accordingly, all of the Company’s banking operations are considered by management to be aggregated in one reportable operating segment. Because the overall banking operations comprise the vast majority of the consolidated operations, no separate segment disclosures are presented. |
Use of Estimates | Use of Estimates — The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Such estimates include, but are not limited to certain fair value measures including the calculation of stock-based compensation, the valuation of goodwill and available for sale and held to maturity securities and the calculation of allowance for credit losses. Actual results could differ from these estimates. |
Securities | Securities —Securities held to maturity are carried at cost, adjusted for the amortization of premiums and the accretion of discounts. Management has the positive intent and the Company has the ability to hold these assets until their estimated maturities. Securities available for sale are carried at fair value. Unrealized gains and losses are excluded from earnings and reported, net of tax, as a separate component of shareholders’ equity until realized. Securities within the available for sale portfolio may be used as part of the Company’s asset/liability strategy and may be sold in response to changes in interest rate risk, prepayment risk or other similar economic factors. For debt securities, when other-than-temporary impairment (“OTTI”) occurs, the amount of the OTTI recognized in earnings depends on whether an entity intends to sell the security or more likely than not will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss. If an entity intends to sell or more likely than not will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss, the OTTI will be recognized in earnings equal to the entire difference between the investment’s amortized cost basis and its fair value at the balance sheet date. If an entity does not intend to sell the security and it is not more likely than not that the entity will be required to sell the security before recovery of its amortized cost basis less any current-period loss, the OTTI will be separated into the amount representing the credit-related portion of the impairment loss (“credit loss”) and the noncredit portion of the impairment loss (“noncredit portion”). The amount of the total OTTI related to the credit loss is determined based on the difference between the present value of cash flows expected to be collected and the amortized cost basis and such difference is recognized in earnings. The amount of the total OTTI related to the noncredit portion is recognized in other comprehensive income, net of applicable taxes. The previous amortized cost basis less the OTTI recognized in earnings shall become the new amortized cost basis of the investment. Premiums and discounts are amortized and accreted to operations using the level-yield method of accounting, adjusted for prepayments as applicable. The specific identification method of accounting is used to compute gains or losses on the sales of these assets. Interest earned on these assets is included in interest income. |
Loans Held for Sale | Loans Held for Sale —Loans held for sale are carried at the lower of aggregate cost or market value. Premiums, discounts and loan fees (net of certain direct loan origination costs) on loans held for sale are deferred until the related loans are sold or repaid. Gains or losses on loan sales are recognized at the time of sale and determined using the specific identification method. |
Loans Held for Investment | Loans Held for Investment —Loans originated and held for investment are stated at the principal amount outstanding, net of unearned fees. The related interest income for multipayment loans is recognized principally by the simple interest method; for single payment loans, such income is recognized using the straight-line method. The Company has two general categories of loans in its portfolio. Loans originated by the Bank and made pursuant to the Company’s loan policy and procedures in effect at the time the loan was made are referred to as “legacy loans” and loans acquired in a business combination are referred to as “acquired loans.” Acquired loans are initially recorded at fair value based on a discounted cash flow valuation methodology that considers, among other things, interest rates, projected default rates, loss given default and recovery rates, with no carryover of any existing allowance for credit losses. Those acquired loans that are renewed or substantially modified after the date of the business combination, thereby subjecting them to the Company’s allowance for credit losses methodology, are referred to as “acquired legacy loans.” Modifications are reviewed for determination of troubled debt restructuring status independently of this process. In certain instances, acquired loans to one borrower may be combined or otherwise re-originated such that they are re-categorized as legacy loans. Acquired loans with a fair value discount or premium at the date of the business combination that remained at the reporting date are referred to as “fair-valued acquired loans.” All fair-valued acquired loans are further categorized into “Non-PCI loans” and “PCI loans” (purchased credit impaired loans). Acquired loans with evidence of credit quality deterioration at acquisition are reviewed to determine if it is probable that the Company will not be able to collect all contractual amounts due, including both principal and interest. When both conditions exist, such loans are accounted for as PCI loans. The Company estimates the total cash flows expected to be collected from the PCI loans, which include undiscounted expected principal and interest, using credit risk, interest rate and prepayment risk assessments that incorporate management’s best estimate of current key assumptions such as default rates, loss severity and payment speeds. The excess of the undiscounted total cash flows expected to be collected over the fair value of the related PCI loans represents the accretable yield, which is recognized as interest income on a level-yield basis over the life of the related loan. The difference between the undiscounted contractual principal and interest and the undiscounted total cash flows expected to be collected is the nonaccretable difference, which reflects the impact of estimated credit losses and other factors. Subsequent increases in expected cash flows will result in a recovery of any previously recorded allowance for credit losses, to the extent applicable, and a reclassification from nonaccretable difference to accretable yield, which is recognized prospectively over the then remaining life of the loan. Subsequent decreases in expected cash flows will result in an impairment charge to the provision for credit losses, resulting in an addition to the allowance for credit losses, and a reclassification from accretable yield to nonaccretable difference. A loan disposal, which may include a loan sale, receipt of payment in full from the borrower or foreclosure, results in removal of the loan from the balance sheet at its allocated carrying amount and accretion of any remaining fair value discount to income. |
Nonrefundable Fees and Costs Associated with Lending Activities | Nonrefundable Fees and Costs Associated with Lending Activities —Loan origination fees in excess of the associated costs are recognized over the life of the related loan as an adjustment to yield using the interest method. Loan commitment fees and loan origination costs are deferred and recognized as an adjustment of yield by the interest method over the related loan life or, if the commitment expires unexercised, recognized in income upon expiration of the commitment. |
Nonperforming and Past Due Loans | Nonperforming and Past Due Loans —Included in the nonperforming loan category are loans which have been categorized by management as nonaccrual because collection of interest is doubtful and loans which have been restructured to provide a reduction in the interest rate or a deferral of interest or principal payments. When the payment of principal or interest on a loan is delinquent for 90 days, or earlier in some cases, the loan is placed on nonaccrual status unless the loan is in the process of collection and the underlying collateral fully supports the carrying value of the loan. If the decision is made to continue accruing interest on the loan, periodic reviews are made to confirm the accruing status of the loan. When a loan is placed on nonaccrual status, interest accrued but not yet collected prior to the determination of uncollectibility is charged to operations. Interest accrued during prior periods is charged to the allowance for credit losses. Any payments received on nonaccrual loans are applied first to outstanding principal of the loan amount, next to the recovery of charged-off loan amounts and finally, any excess is treated as recovery of lost interest. Restructured loans are those loans on which concessions in terms have been granted because of a borrower’s financial difficulty. Interest is generally not accrued on such loans in accordance with the new terms. |
Allowance for Credit Losses | Allowance for Credit Losses — The allowance for credit losses is a valuation allowance available for losses incurred on loans. All losses are charged to the allowance when the loss actually occurs or when a determination is made that such a loss is probable and reasonably estimatable. Recoveries are credited to the allowance at the time of recovery. Throughout the year, management estimates the probable level of losses to determine whether the allowance for credit losses is adequate to absorb losses inherent in the loan portfolio. Based on these estimates, an amount is charged to the provision for credit losses and credited to the allowance for credit losses in order to adjust the allowance to a level determined to be adequate to absorb losses. In making its evaluation of the adequacy of the allowance for credit losses, management considers factors such as historical loan loss experience, the amount of nonperforming assets and related collateral, the volume, growth and composition of the Company’s loan portfolio, current economic conditions that may affect the borrower’s ability to pay and the value of collateral, the evaluation of the Company’s loan portfolio through its internal loan review process and other relevant factors. Estimates of credit losses involve an exercise of judgment. While it is possible that in the short term the Company may sustain losses which are substantial in relation to the allowance for credit losses, it is the judgment of management that the allowance for credit losses reflected in the consolidated balance sheets is adequate to absorb probable losses that exist in the loan portfolio as of December 31, 2017. The Company’s allowance for credit losses consists of two elements: (1) specific valuation allowances based on probable losses on impaired loans; and (2) a general valuation allowance based on historical loan loss experience, general economic conditions and other qualitative risk factors both internal and external to the Company. A loan is defined as impaired if, based on current information and events, it is probable that a creditor will be unable to collect all amounts due, both interest and principal, according to the contractual terms of the loan agreement. The allowance for credit losses related to impaired loans is determined based on the difference of carrying value of loans and the present value of expected cash flows discounted at the loan’s effective interest rate or, as a practical expedient, the loan’s observable market price or the fair value of the collateral if the loan is collateral dependent. Loans acquired in business combinations are initially recorded at fair value, which includes an estimate of credit losses expected to be realized over the remaining lives of the loans, and therefore no corresponding allowance for credit losses is recorded for these loans at acquisition. These fair value estimates associated with acquired loans, based on a discounted cash flow model, include estimates related to market interest rates and undiscounted projections of future cash flows that incorporate expectations of prepayments and the amount and timing of principal, interest and other cash flows, as well as any shortfalls thereof. At period-end after acquisition, the fair-valued acquired loans from each acquisition are reassessed to determine whether an addition to the allowance for credit losses is appropriate due to further credit quality deterioration. Methods utilized to estimate any subsequently required allowance for acquired loans not deemed credit impaired at acquisition are similar to originated loans; however, the estimate of loss is based on the unpaid principal balance and then compared to any remaining unaccreted purchase discount. To the extent that the calculated loss is greater than the remaining unaccreted purchase discount, an allowance is recorded for such difference. |
Premises and Equipment | Premises and Equipment —Premises and equipment are carried at cost less accumulated depreciation. Depreciation expense is computed principally using the straight-line method over the estimated useful lives of the assets which range from three to 39 years. Leasehold improvements are amortized using the straight-line method over the periods of the leases or the estimated useful lives, whichever is shorter. |
Goodwill | Goodwill —Goodwill is annually assessed for impairment or when events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. Under Accounting Standards Codification (“ASC”) topic 350-20, “Intangibles—Goodwill and Other—Goodwill” If the Company bypasses the qualitative assessment, a two-step goodwill impairment test would be performed. The first step of the goodwill impairment test compares the estimated fair value of the Company’s reporting unit to its carrying value. If the estimated fair value of the reporting unit exceeds its carrying value, goodwill of the reporting unit is not impaired. If the estimated fair value of the reporting unit is less than the carrying value, the second step must be performed to determine the implied fair value of the reporting unit’s goodwill and the amount of goodwill impairment, if any. The Company currently utilizes a qualitative assessment for its annual goodwill impairment analysis. |
Amortization of Core Deposit Intangibles | Amortization of Core Deposit Intangibles —Core deposit intangibles are being amortized on a non-pro rata basis over an estimated life of 10 to 15 years. |
Income Taxes | Income Taxes — The Company files a consolidated federal income tax return and a consolidated Oklahoma state income tax return. Since 2014, the Bank files an Arkansas state income tax return. Deferred tax assets and liabilities are recognized for the estimated tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and are recorded in other assets or other liabilities on the Company’s consolidated balance sheets. The Company records uncertain tax positions in accordance with ASC topic 740 “ Income Taxes Realization of net deferred tax assets is based upon the level of historical income and on estimates of future taxable income. Although realization is not assured, management believes it is more likely than not that all of the net deferred tax assets will be realized. Interest and/or penalties related to income taxes are reported as a component of income tax expense. Beginning in 2017, the income tax effects related to settlements of share-based payment awards are reported in earnings as an increase (or decrease) to income tax expense (see Note 11 - Income Taxes). |
Stock-Based Compensation | Stock-Based Compensation —The Company accounts for stock-based employee compensation plans using the fair value-based method of accounting. The expense associated with stock-based compensation is recognized over the vesting period of each individual arrangement. The fair value of stock options granted is estimated at the date of grant using the Black-Scholes option-pricing model. This model requires the input of subjective assumptions. The fair value of restricted stock awards is based on the current market price on the date of grant. |
Cash and Cash Equivalents | Cash and Cash Equivalents — For purposes of reporting cash flows, cash and cash equivalents include cash and due from banks as well as federal funds sold that mature in three days or less. |
Earnings Per Common Share | Earnings Per Common Share —Basic earnings per common share are calculated using the two-class method. The two-class method provides that unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and shall be included in the computation of basic earnings per share. Diluted earnings per common share is computed using the weighted-average number of shares determined for the basic earnings per common share computation plus the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock using the treasury stock method. As of December 31, 2017, all outstanding stock options issued by the Company have been exercised and there is no potential dilution of weighted-average shares. The following table illustrates the computation of basic and diluted earnings per share: Year Ended December 31, 2017 2016 2015 Amount Per Share Amount Amount Per Share Amount Amount Per Share Amount (Amounts in thousands, except per share data) Net income $ 272,165 $ 274,466 $ 286,646 Basic: Weighted average shares outstanding 69,484 $ 3.92 69,674 $ 3.94 70,033 $ 4.09 Diluted: Add incremental shares for: Effect of dilutive securities - options — 6 16 Total 69,484 $ 3.92 69,680 $ 3.94 70,049 $ 4.09 There were no stock options exercisable at December 31, 2017, 2016 and 2015 that would have had an anti-dilutive effect on the above computation. |
New Accounting Standards | New Accounting Standards Accounting Standards Updates (“ASU”) ASU 2018-02, “Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” The amendments of ASU 2018-02 allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. ASU 2018-02 is effective for all entities beginning January 1, 2019 and is not expected to have a significant impact on the Company’s financial statements. ASU 2017-04, ASU 2017-04 simplifies the subsequent measurement of goodwill by eliminating the second step of the goodwill impairment test, which required computing the implied fair value of goodwill. Under the amendments in this update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. ASU 2017-04 will be effective for the Company on January 1, 2020 and is not expected to have a significant impact on the Company’s financial statements. ASU 2017-01, ASU 2017-01 is intended to clarify or correct unintended application of ASU 2017-01 clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. Additionally, the amendments in this update provide a more robust framework to assist entities in evaluating whether a set of assets and activities constitutes a business. Lastly, the amendments in this update narrow the definition of the term output so that the term is consistent with how outputs are described in Topic 606. ASU 2017-01 is effective for the Company on January 1, 2018 and is not expected to have a significant impact on the Company’s financial statements. ASU 2016-18, ASU 2016-18 requires the Statement of Cash Flows to explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. Therefore, restricted cash or cash equivalents should be included with cash and cash equivalents when recording the beginning-of-period and end-of-period total amounts on the Statement of Cash Flows. ASU 2016-18 is effective for the Company on January 1, 2018 and is not expected to have a significant impact on the Company’s financial statements. ASU 2016-15, ASU 2016-15 addresses certain cash receipts and cash payments with the objective of reducing the existing diversity in practice. ASU 2016-15 is effective for the Company on January 1, 2018 and is not expected to have a significant impact on the Company's financial statements. ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326)—Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 requires a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. An entity must use judgment in determining the relevant information and estimation methods that are appropriate in its circumstances. Additionally, available for sale debt securities may realize value either through collection of contractual cash flows or through sale of the security at fair value. Therefore, the amendments limit the amount of the allowance for credit losses to the difference between amortized cost and fair value. ASU 2016-13 will be effective for the Company as of January 1, 2020. The Company is currently evaluating the potential impact of ASU 2016-13 on the Company’s financial statements. ASU 2016-09, “Compensation - Stock Compensation (Topic 718)—Improvements to Employee Share-Based Payment Accounting.” ASU 2016-09 simplifies the accounting for share-based awards paid to employees. The amended guidance 1) requires excess tax benefits and tax deficiencies on share-based awards payments to employees to be recognized directly to income tax expense or benefit in the Consolidated Statement of Income rather than to capital surplus; 2) requires excess tax benefits to be included as operating activities on the Consolidated Statements of Cash Flows; 3) provides entities with the option of making an accounting policy election to account for forfeitures of share-based payments as they occur instead of estimating the awards expected to be forfeited; and 4) changes the threshold to qualify for equity classification to permit withholdings up to the maximum statutory tax rate in the applicable jurisdiction. In addition, excess tax benefits and tax deficiencies are considered discrete items in the reporting period they occur and are not included in the estimate of an entity’s annual effective tax rate. The Company adopted ASU 2016-09 on January 1, 2017 and elected to recognize forfeitures as they occur. Implementation of ASU 2016-09 will add volatility to tax expense as the Company’s stock price changes. The adoption of ASU 2016-09 did not have a significant impact on the Company’s financial statements. ASU 2016-02, "Leases (Topic 842)." ASU 2016-02 requires that lessees and lessors recognize lease assets and lease liabilities on the balance sheet and disclose key information about leasing arrangements. ASU 2016-02 is effective for public companies for annual periods beginning January 1, 2019, including interim periods within those fiscal years. The Company is currently evaluating the potential impact of ASU 2016-02 on the Company’s financial statements. ASU 2016-01 “Financial Instruments—Overall (Subtopic 825-10) Recognition and Measurement of Financial Assets and Financial Liabilities” ASU 2016-01 addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. ASU 2016-01 (1) requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income; (2) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; (3) eliminates the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities; (4) eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet; (5) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; (6) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments; (7) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements; and (8) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. The amendments in this update affect all entities that hold financial assets or owe financial liabilities. ASU 2016-01 is effective for the Company on January 1, 2018 and is not expected to have a significant impact on the Company’s financial statements. ASU 2014-09, “Revenue from Contracts with Customers (Topic 606).” ASU 2014-09 supersedes the revenue recognition requirements in Revenue Recognition (Topic 605), and most industry-specific guidance throughout the Industry Topics of the Codification. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, the FASB has issued targeted updates to clarify specific implementation issues of ASU 2014-09. These updates include ASU 2016-08 - ASU 2016-10 - ASU 2016-12 - and ASU 2016-20 - s. These amendments do not change the core principles in ASU 2014-09. The Company’s primary sources of revenue are comprised of net interest income on financial assets and liabilities, which are not within the scope of ASU 2014-09. ASU 2014-09 is effective for the Company on January 1, 2018, with a cumulative-effect adjustment, and will not have a significant impact on the financial statements. |
