Basis Of Presentation [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	BASIS OF PRESENTATION The accompanying unaudited consolidated financial statements of Zions Bancorporation (“the Parent”) and its majority-owned subsidiaries (collectively “the Company,” “Zions,” “we,” “our,” “us”) have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. References to GAAP, including standards promulgated by the Financial Accounting Standards Board (“FASB”), are made according to sections of the Accounting Standards Codification (“ASC”) and to Accounting Standards Updates (“ASU”), which include consensus issues of the Emerging Issues Task Force (“EITF”). In certain cases, ASUs are issued jointly with International Financial Reporting Standards (“IFRS”). Certain prior period amounts have been reclassified to conform with the current period presentation. These reclassifications did not affect net income. Operating results for the three and six months ended June 30, 2015 and 2014 are not necessarily indicative of the results that may be expected in future periods. The consolidated balance sheet at December 31, 2014 is from the audited financial statements at that date, but does not include all of the information and footnotes required by GAAP for complete financial statements. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s 2014 Annual Report on Form 10-K. The Company provides a full range of banking and related services through subsidiary banks in 11 Western and Southwestern states as follows: Zions First National Bank (“Zions Bank”), in Utah, Idaho and Wyoming; Amegy Corporation (“Amegy”) and its subsidiary, Amegy Bank, in Texas; California Bank & Trust (“CB&T”); National Bank of Arizona (“NBAZ”); Nevada State Bank (“NSB”); Vectra Bank Colorado (“Vectra”), in Colorado and New Mexico; and The Commerce Bank of Washington (“TCBW”), in Washington and Oregon. Effective April 1, 2015, The Commerce Bank of Oregon (“TCBO”) was merged into TCBW. The Parent and its subsidiary banks also own and operate certain nonbank subsidiaries that engage in financial services. On June 1, 2015, the Company announced certain efficiency and restructuring initiatives that included, among other things, the consolidation of its seven bank charters into one bank charter. This change is subject to regulatory approval and is currently expected to be completed within the next 6 to 12 months.

Certain Recent Accounting Pronouncements [Abstract]
Certain Recent Accounting Pronouncements [Text Block]	2. RECENT ACCOUNTING PRONOUNCEMENTS Standard Description Date of adoption Effect on the financial statements or other significant matters Standards not yet adopted by the Company ASU 2015-07, Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or its Equivalent), (Topic 820) The guidance eliminates the current requirement to categorize within the fair value hierarchy investments whose fair values are measured at net asset value (“NAV”) using the practical expedient in ASC 820. Fair value disclosure of these investments will be made to facilitate reconciliation to amounts reported on the balance sheet. Other related disclosures will continue when the NAV practical expedient is used. Adoption is retrospective and early adoption is permitted. January 1, 2016 We do not currently expect this new disclosure guidance will have a material impact on the Company’s financial statements. Standard Description Date of adoption Effect on the financial statements or other significant matters Standards not yet adopted by the Company (continued) ASU 2015-05, Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement (Subtopic 350-40) The standard provides guidance to determine whether an arrangement includes a software license. If it does, the customer accounts for it the same way as for other software licenses. If no software license is included, the customer accounts for it as a service contract. Adoption may be retrospective or prospective. Early adoption is permitted. January 1, 2016 We are currently evaluating the impact this new guidance may have on the Company’s financial statements. ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs (Subtopic 835-30) The standard requires that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of the associated debt liability, consistent with debt discounts. Adoption is retrospective and early adoption is permitted. January 1, 2016 We currently include debt issuance costs in other assets. The amount to be reclassified to the debt liability is not material to the Company’s financial statements. ASU 2015-02, Amendments to the Consolidation Analysis (Topic 810) The new standard changes certain criteria in the variable interest model and the voting model to determine whether certain legal entities are variable interest entities (“VIEs”) and whether they should be consolidated. Additional disclosures are required regarding entities not currently considered VIEs, but may become VIEs under the new guidance and may be subject to consolidation. Adoption may be retrospective or modified retrospective with a cumulative effect adjustment. Early adoption is permitted. January 1, 2016 We currently do not consolidate any VIEs and do not expect this new guidance will have a material impact on the Company’s financial statements. ASU 2014-09, Revenue from Contracts with Customers (Topic 606) The core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The banking industry does not expect significant changes because major sources of revenue are from financial instruments that have been excluded from the scope of the new standard, (including loans, derivatives, debt and equity securities, etc.). However, the new standard affects other fees charged by banks, such as asset management fees, credit card interchange fees, deposit account fees, etc. Adoption may be made on a full retrospective basis with practical expedients, or on a modified retrospective basis with a cumulative effect adjustment. Early adoption may be made as of the current effective date, assuming deferral is enacted. January 1, 2017 (FASB announced on July 9, 2015 a one-year deferral from effective date shown above; ASU still to be issued.) While we currently do not expect this standard will have a material impact on the Company’s financial statements, we are still in process of conducting our evaluation. Standards adopted by the Company ASU 2014-14, Classification of Certain Government-Guaranteed Mortgage Loans upon Foreclosure (Subtopic 310-40) The standard addresses the classification of certain foreclosed mortgage loans fully or partially guaranteed under government programs. Under certain such programs, qualifying creditors can extend mortgage loans with a guarantee entitling the creditor to recover all or a portion of the unpaid principal balance from the government if the borrower defaults. A separate other receivable is established that is measured based on the amount of the loans expected to be recovered. January 1, 2015 Our adoption of this standard had no impact on the accompanying financial statements. Standard Description Date of adoption Effect on the financial statements or other significant matters Standards adopted by the Company (continued) ASU 2014-04, Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure (Subtopic 310-40) The standard clarifies that a creditor should be considered to have physical possession of a residential real estate property collateralizing a residential mortgage loan and thus would reclassify the loan to other real estate owned when certain conditions are satisfied. Additional financial statement disclosures will be required. January 1, 2015 Our adoption of this standard added a nominal amount of additional disclosure to Note 6. ASU 2014-01, Accounting for Investments in Qualified Affordable Housing Projects (Topic 323) The standard revised conditions an entity must meet to elect the effective yield method when accounting for qualified affordable housing project investments. The EITF final consensus changed the method of amortizing a Low-Income Housing Tax Credit (“LIHTC”) investment from the effective yield method to a proportional amorti-zation method. Amortization would be proportional to the tax credits and tax benefits received but, under a practical expedient available in certain circumstances, amortization could be proportional to only the tax credits. Reporting entities that invest in LIHTC investments through a limited liability entity could elect the proportional amortization method if certain conditions are met. January 1, 2015 Our adoption of this standard did not have a material impact on the accompanying financial statements.

Unrealized losses included in OCI at March 31, 2015 were $148 million . We also received approximately $13 million in paydowns and payoffs of CDO securities during the quarter prior to the sale of the CDOs. During the first quarter of 2015 , we reclassified all of the remaining held-to-maturity (“HTM”) CDO securities, or approximately $79 million at amortized cost, to available-for-sale (“AFS”) securities. The reclassification resulted from increased risk weights for these securities under the new Basel III capital rules, and was made in accordance with applicable accounting guidance that allows for such reclassifications when increased risk weights of debt securities must be used for regulatory risk-based capital purposes. No gain or loss was recognized in the statement of income at the time of reclassification. During the first half of 2014 , we recorded a total of $1,018 million par amount of sales and paydowns of CDO securities, resulting in net gains of approximately $36 million . These sales were made in part as a result of the Volcker Rule (“VR”). Maturities The amortized cost and estimated fair value of investment debt securities are shown subsequently as of June 30, 2015 by expected timing of principal payments. Actual principal payments may differ from contractual or expected principal payments because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

Other-Than-Temporary Impairment Ongoing Policy We review investment securities on a quarterly basis for the presence of other-than-temporary impairment (“OTTI”). We assess whether OTTI is present when the fair value of a debt security is less than its amortized cost basis at the balance sheet date (the majority of the investment portfolio are debt securities). Under these circumstances, OTTI is considered to have occurred if (1) we have formed a documented intent to sell identified securities or initiated such sales; (2) it is “more likely than not” we will be required to sell the security before recovery of its amortized cost basis; or (3) the present value of expected cash flows is not sufficient to recover the entire amortized cost basis. Noncredit-related OTTI in securities we intend to sell is recognized in earnings as is any credit-related OTTI in securities, regardless of our intent. Noncredit-related OTTI on AFS securities not expected to be sold is recognized in OCI. The amount of noncredit-related OTTI in a security is quantified as the difference in a security’s amortized cost after adjustment for credit impairment, and its lower fair value. Presentation of OTTI is made in the statement of income on a gross basis with an offset for the amount of OTTI recognized in OCI. OTTI Conclusions Our 2014 Annual Report on Form 10-K describes in more detail our OTTI evaluation process. The following summarizes the conclusions from our OTTI evaluation by each security type that has significant gross unrealized losses at June 30, 2015 : OTTI – U.S. Government Agencies and Corporations Agency Securities: These securities were issued by the Federal Agricultural Mortgage Corporation (“FAMC”) and the Export-Import Bank of the U.S. These securities are floating-rate and were purchased at premiums or discounts. They have maturity dates from 1 to 25 years and have contractual cash flows guaranteed by agencies of the U.S. Government. Unrealized losses relate to changes in interest rates subsequent to purchase and are not attributable to credit. At June 30, 2015 , we did not have an intent to sell identified securities with unrealized losses or initiate such sales, and we believe it is more likely than not we would not be required to sell such securities before recovery of their amortized cost basis. Therefore, we did not record OTTI for these securities during the second quarter of 2015 . Agency Guaranteed Mortgage-Backed Securities: These pass-through securities are comprised largely of fixed and floating-rate residential mortgage-backed securities issued by the Government National Mortgage Association (“GNMA”), the Federal National Mortgage Association, or the Federal Home Loan Mortgage Corporation. They were generally purchased at premiums with maturity dates from 10 to 15 years for fixed-rate securities and 30 years for floating-rate securities. These securities benefit from certain guarantee provisions or, in the case of GNMA, direct U.S. government guarantees. Unrealized losses relate to changes in interest rates subsequent to purchase and are not attributable to credit. At June 30, 2015 , we did not have an intent to sell identified securities with unrealized losses or initiate such sales, and we believe it is more likely than not we would not be required to sell such securities before recovery of their amortized cost basis. Therefore, we did not record OTTI for these securities during the second quarter of 2015 . Small Business Administration (“SBA”) Loan-Backed Securities: These securities were generally purchased at premiums with maturities from 5 to 25 years and have principal cash flows guaranteed by the SBA. Unrealized losses relate to changes in interest rates subsequent to purchase and are not attributable to credit. At June 30, 2015 , we did not have an intent to sell identified SBA securities with unrealized losses or initiate such sales, and we believe it is more likely than not we would not be required to sell such securities before recovery of their amortized cost basis. Therefore, we did not record OTTI for these securities during the second quarter of 2015 .

Securities are also pledged as collateral for security repurchase agreements. Private Equity Investments Effect of Volcker Rule The VR, as published pursuant to the Dodd-Frank Act in December 2013 and amended in January 2014, significantly restricted certain activities by covered bank holding companies, including restrictions on certain types of securities, proprietary trading, and private equity investing. The Company’s private equity investments (“PEIs”) consist of Small Business Investment Companies (“SBICs”) and non-SBICs. As of December 31, 2014 , the only prohibited investments under the VR requiring divestiture by the Company were certain of its PEIs. Of the recorded PEIs of $131 million at June 30, 2015 , approximately $25 million remain prohibited by the VR. As of June 30, 2015 , we have sold a total of approximately $17 million of PEIs as follows: $4 million during the second quarter of 2015, $5 million during the first quarter of 2015 , and $8 million during 2014 . All of these sales related to prohibited PEIs. The 2015 sales resulted in insignificant amounts of realized gains or losses. We will dispose of the remaining $25 million of prohibited PEIs before the required deadline. However, the required deadline has been extended to July 21, 2016 from July 21, 2015 and the Federal Reserve has announced its intention to act in 2015 to grant an additional one-year extension to July 21, 2017. See other discussions in Notes 10 and 11. As discussed in Note 11, we have $48 million at June 30, 2015 of unfunded commitments for PEIs, of which approximately $7 million relate to prohibited PEIs. Until we dispose of the prohibited PEIs, we expect to fund these commitments if and as the capital calls are made, as allowed under the VR.

Owner occupied and commercial real estate (“CRE”) loans include unamortized premiums of approximately $31.1 million at June 30, 2015 and $36.5 million at December 31, 2014 . Municipal loans generally include loans to municipalities with the debt service being repaid from general funds or pledged revenues of the municipal entity, or to private commercial entities or 501(c)(3) not-for-profit entities utilizing a pass-through municipal entity to achieve favorable tax treatment. Land development loans included in the construction and land development loan class were $419.4 million at June 30, 2015 and $484.9 million at December 31, 2014 . Loans with a carrying value of approximately $22.4 billion at June 30, 2015 and $22.5 billion at December 31, 2014 have been pledged at the Federal Reserve and various Federal Home Loan Banks (“FHLBs”) as collateral for potential borrowings. We sold loans with a carrying value of $335.8 million and $636.2 million for the three and six months ended June 30, 2015 , and $260.1 million and $597.7 million , for the three and six months ended June 30, 2014 , respectively, that were classified as loans held for sale. The sold loans were derecognized from the balance sheet. Loans classified as loans held for sale primarily consist of conforming residential mortgages and the guaranteed portion of SBA loans. The principal balance of sold loans for which we retain servicing was approximately $1.2 billion at both June 30, 2015 and December 31, 2014 . Amounts added to loans held for sale during these periods were $359.0 million and $668.7 million for the three and six months ended June 30, 2015 , and $301.6 million and $597.1 million for the three and six months ended June 30, 2014 , respectively. Income from loans sold, excluding servicing, was $4.3 million and $8.9 million for the three and six months ended June 30, 2015 , and $3.6 million and $7.1 million for the three and six months ended June 30, 2014 , respectively. Since 2009, CB&T and NSB have had loss sharing agreements with the Federal Deposit Insurance Corporation (“FDIC”), which provided indemnification for credit losses of acquired loans and foreclosed assets up to specified thresholds. The last of the agreements for commercial loans, which comprised the major portion of the acquired portfolio, expired as of September 30, 2014. The agreements for 1-4 family residential loans will expire in 2019. In previous periods, the FDIC-supported loan balances were presented separately in this footnote and in other disclosures, and included purchased credit-impaired (“PCI”) loans, as subsequently discussed in Purchased Loans. Due to declining balances, for all periods presented herein, the FDIC-supported/PCI loans have been reclassified to their respective loan segments and classes. Allowance for Credit Losses The allowance for credit losses (“ACL”) consists of the allowance for loan and lease losses (“ALLL”) (also referred to as the allowance for loan losses) and the reserve for unfunded lending commitments (“RULC”). Allowance for Loan and Lease Losses The ALLL represents our estimate of probable and estimable losses inherent in the loan and lease portfolio as of the balance sheet date. Losses are charged to the ALLL when recognized. Generally, commercial loans are charged off or charged down when they are determined to be uncollectible in whole or in part, or when 180 days past due unless the loan is well secured and in process of collection. Consumer loans are either charged off or charged down to net realizable value no later than the month in which they become 180 days past due. Closed-end consumer loans that are not secured by residential real estate are either charged off or charged down to net realizable value no later than the month in which they become 120 days past due. We establish the amount of the ALLL by analyzing the portfolio at least quarterly, and we adjust the provision for loan losses so the ALLL is at an appropriate level at the balance sheet date. We determine our ALLL as the best estimate within a range of estimated losses. The methodologies we use to estimate the ALLL depend upon the impairment status and portfolio segment of the loan. The methodology for impaired loans is discussed subsequently. For the commercial and CRE segments, we use a comprehensive loan grading system to assign probability of default (“PD”) and loss given default (“LGD”) grades to each loan. The credit quality indicators discussed subsequently are based on this grading system. In addition, loan officers utilize their experience and judgment in assigning PD and LGD grades, subject to confirmation of the PD and LGD by either credit risk or credit examination. We create groupings of these grades for each subsidiary bank and loan class and calculate historic loss rates using a loss migration analysis that attributes historic realized losses to these loan grade groupings over the period of January 2008 through the most recent full quarter. For the consumer loan segment, we use roll rate models to forecast probable inherent losses. Roll rate models measure the rate at which consumer loans migrate from one delinquency category to the next worse delinquency category, and eventually to loss. We estimate roll rates for consumer loans using recent delinquency and loss experience by segmenting our consumer loan portfolio into separate pools based on common risk characteristics and separately calculating historical delinquency and loss experience for each pool. These roll rates are then applied to current delinquency levels to estimate probable inherent losses. When long-term average losses exceed those losses estimated through roll rates, we use long-term average loss rates for the applicable pools. Roll rates incorporate housing market trends inasmuch as these trends manifest themselves in charge-offs and delinquencies. In addition, our qualitative and environmental factors discussed subsequently incorporate the most recent housing market trends. The current status and historical changes in qualitative and environmental factors may not be reflected in our quantitative models. Thus, after applying historical loss experience, as described above, we review the quantitatively derived level of ALLL for each segment using qualitative criteria and use those criteria to determine our estimate within the range. We track various risk factors that influence our judgment regarding the level of the ALLL across the portfolio segments. These factors primarily include: • Asset quality trends • Risk management and loan administration practices • Risk identification practices • Effect of changes in the nature and volume of the portfolio • Existence and effect of any portfolio concentrations • National economic and business conditions • Regional and local economic and business conditions • Data availability and applicability • Effects of other external factors The magnitude of the impact of these factors on our qualitative assessment of the ALLL changes from quarter to quarter according to changes made by management in its assessment of these factors, the extent these factors are already reflected in historic loss rates, and the extent changes in these factors diverge from one to another. We also consider the uncertainty inherent in the estimation process when evaluating the ALLL. Reserve for Unfunded Lending Commitments We also estimate a reserve for potential losses associated with off-balance sheet commitments, including standby letters of credit. We determine the RULC using the same procedures and methodologies that we use for the ALLL. The loss factors used in the RULC are the same as the loss factors used in the ALLL, and the qualitative adjustments used in the RULC are the same as the qualitative adjustments used in the ALLL. We adjust the Company’s unfunded lending commitments that are not unconditionally cancelable to an outstanding amount equivalent using credit conversion factors, and we apply the loss factors to the outstanding equivalents.

10,113,008 $ 8,506,286 $ 40,063,658 Nonaccrual and Past Due Loans Loans are generally placed on nonaccrual status when payment in full of principal and interest is not expected, or the loan is 90 days or more past due as to principal or interest, unless the loan is both well secured and in the process of collection. Factors we consider in determining whether a loan is placed on nonaccrual include delinquency status, collateral value, borrower or guarantor financial statement information, bankruptcy status, and other information which would indicate that the full and timely collection of interest and principal is uncertain. A nonaccrual loan may be returned to accrual status when all delinquent interest and principal become current in accordance with the terms of the loan agreement; the loan, if secured, is well secured; the borrower has paid according to the contractual terms for a minimum of six months; and analysis of the borrower indicates a reasonable assurance of the ability and willingness to maintain payments. Payments received on nonaccrual loans are applied as a reduction to the principal outstanding. Closed-end loans with payments scheduled monthly are reported as past due when the borrower is in arrears for two or more monthly payments. Similarly, open-end credit such as charge-card plans and other revolving credit plans are reported as past due when the minimum payment has not been made for two or more billing cycles. Other multi-payment obligations (i.e., quarterly, semiannual, etc.), single payment, and demand notes are reported as past due when either principal or interest is due and unpaid for a period of 30 days or more.

Credit Quality Indicators In addition to the past due and nonaccrual criteria, we also analyze loans using loan risk grading systems, which vary based on the size and type of credit risk exposure. The internal risk grades assigned to loans follow our definitions of Pass, Special Mention, Substandard, and Doubtful, which are consistent with published definitions of regulatory risk classifications. Definitions of Pass, Special Mention, Substandard, and Doubtful are summarized as follows: Pass – A Pass asset is higher quality and does not fit any of the other categories described below. The likelihood of loss is considered remote. Special Mention – A Special Mention asset has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the bank’s credit position at some future date. Substandard – A Substandard asset is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified have well-defined weaknesses and are characterized by the distinct possibility that the bank may sustain some loss if deficiencies are not corrected. Doubtful – A Doubtful asset has all the weaknesses inherent in a Substandard asset with the added characteristics that the weaknesses make collection or liquidation in full highly questionable and improbable. We generally assign internal risk grades to commercial and CRE loans with commitments equal to or greater than $750,000 based on financial and statistical models, individual credit analysis, and loan officer judgment. For these larger loans, we assign one of multiple grades within the Pass classification or one of the following four grades: Special Mention, Substandard, Doubtful, and Loss. Loss indicates that the outstanding balance has been charged off. We confirm our internal risk grades quarterly, or as soon as we identify information that affects the credit risk of the loan. For consumer loans or certain small commercial loans with commitments equal to or less than $750,000 , we generally assign internal risk grades similar to those described previously based on automated rules that depend on refreshed credit scores, payment performance, and other risk indicators. These are generally assigned either a Pass or Substandard grade and are reviewed as we identify information that might warrant a grade change.

For our non-purchased credit-impaired loans, if a nonaccrual loan has a balance greater than $1 million , or if a loan is a troubled debt restructuring (“TDR”), including TDRs that subsequently default, or if the loan is no longer reported as a TDR, we individually evaluate the loan for impairment and estimate a specific reserve for the loan for all portfolio segments under applicable accounting guidance. Smaller nonaccrual loans are pooled for ALLL estimation purposes. PCI loans are included in impaired loans and are accounted for under separate accounting guidance. See subsequent discussion under Purchased Loans. When a loan is impaired, we estimate a specific reserve for the loan based on the projected present value of the loan’s future cash flows discounted at the loan’s effective interest rate, the observable market price of the loan, or the fair value of the loan’s underlying collateral. The process of estimating future cash flows also incorporates the same determining factors discussed previously under nonaccrual loans. When we base the impairment amount on the fair value of the loan’s underlying collateral, we generally charge off the portion of the balance that is impaired, such that these loans do not have a specific reserve in the ALLL. Payments received on impaired loans that are accruing are recognized in interest income, according to the contractual loan agreement. Payments received on impaired loans that are on nonaccrual are not recognized in interest income, but are applied as a reduction to the principal outstanding. The amount of interest income recognized on a cash basis during the time the loans were impaired within the three and six months ended June 30, 2015 and 2014 was not significant. Information on impaired loans individually evaluated is summarized as follows at June 30, 2015 and December 31, 2014 , including the average recorded investment and interest income recognized for the three and six months ended June 30, 2015 and 2014 : June 30, 2015 (In thousands) Unpaid principal balance Recorded investment Total recorded investment Related allowance with no allowance with allowance Commercial: Commercial and industrial $ 212,734 $ 39,539 $ 142,328 $ 181,867 $ 31,670 Owner occupied 164,116 89,799 53,931 143,730 4,804 Municipal 1,471 992 — 992 — Total commercial 378,321 130,330 196,259 326,589 36,474 Commercial real estate: Construction and land development 50,251 9,300 24,579 33,879 973 Term 174,299 99,624 46,443 146,067 2,127 Total commercial real estate 224,550 108,924 71,022 179,946 3,100 Consumer: Home equity credit line 29,015 15,390 10,361 25,751 497 1-4 family residential 81,050 28,841 39,264 68,105 9,732 Construction and other consumer real estate 3,232 1,216 1,123 2,339 190 Other 4,673 — 3,751 3,751 173 Total consumer loans 117,970 45,447 54,499 99,946 10,592 Total $ 720,841 $ 284,701 $ 321,780 $ 606,481 $ 50,166 December 31, 2014 (In thousands) Unpaid principal balance Recorded investment Total recorded investment Related allowance with no allowance with allowance Commercial: Commercial and industrial $ 185,520 $ 43,257 $ 103,565 $ 146,822 $ 22,852 Owner occupied 198,231 83,179 86,382 169,561 6,087 Municipal 1,535 1,056 — 1,056 — Total commercial 385,286 127,492 189,947 317,439 28,939 Commercial real estate: Construction and land development 60,993 16,500 26,977 43,477 1,773 Term 203,788 96,351 63,740 160,091 2,345 Total commercial real estate 264,781 112,851 90,717 203,568 4,118 Consumer: Home equity credit line 30,209 14,798 11,883 26,681 437 1-4 family residential 86,575 37,096 35,831 72,927 8,494 Construction and other consumer real estate 3,902 1,449 1,410 2,859 233 Other 6,580 — 5,254 5,254 133 Total consumer loans 127,266 53,343 54,378 107,721 9,297 Total $ 777,333 $ 293,686 $ 335,042 $ 628,728 $ 42,354 Three Months Ended Six Months Ended (In thousands) Average recorded investment Interest income recognized Average recorded investment Interest income recognized Commercial: Commercial and industrial $ 174,911 $ 2,831 $ 155,584 $ 4,255 Owner occupied 144,613 3,186 142,817 6,970 Municipal 1,008 — 1,021 — Total commercial 320,532 6,017 299,422 11,225 Commercial real estate: Construction and land development 35,562 1,628 36,215 2,177 Term 144,054 5,063 142,439 10,038 Total commercial real estate 179,616 6,691 178,654 12,215 Consumer: Home equity credit line 25,400 416 24,948 821 1-4 family residential 69,874 534 68,464 1,041 Construction and other consumer real estate 2,497 22 2,529 64 Bankcard and other revolving plans — 1 1 100 Other 4,176 230 4,463 516 Total consumer loans 101,947 1,203 100,405 2,542 Total $ 602,095 $ 13,911 $ 578,481 $ 25,982 Three Months Ended Six Months Ended (In thousands) Average recorded investment Interest income recognized Average recorded investment Interest income recognized Commercial: Commercial and industrial $ 194,683 $ 4,212 $ 188,136 $ 6,802 Owner occupied 232,662 4,532 236,250 9,286 Municipal 9,270 — 9,615 — Total commercial 436,615 8,744 434,001 16,088 Commercial real estate: Construction and land development 61,957 1,394 64,265 4,932 Term 245,827 6,618 260,749 20,568 Total commercial real estate 307,784 8,012 325,014 25,500 Consumer: Home equity credit line 25,854 372 25,470 774 1-4 family residential 82,353 512 81,909 1,052 Construction and other consumer real estate 3,164 36 3,166 74 Bankcard and other revolving plans — 1 5 1 Other 7,314 421 7,854 930 Total consumer loans 118,685 1,342 118,404 2,831 Total $ 863,084 $ 18,098 $ 877,419 $ 44,419 Modified and Restructured Loans Loans may be modified in the normal course of business for competitive reasons or to strengthen the Company’s position. Loan modifications and restructurings may also occur when the borrower experiences financial difficulty and needs temporary or permanent relief from the original contractual terms of the loan. These modifications are structured on a loan-by-loan basis and, depending on the circumstances, may include extended payment terms, a modified interest rate, forgiveness of principal, or other concessions. Loans that have been modified to accommodate a borrower who is experiencing financial difficulties, and for which the Company has granted a concession that it would not otherwise consider, are considered TDRs. We consider many factors in determining whether to agree to a loan modification involving concessions, and seek a solution that will both minimize potential loss to the Company and attempt to help the borrower. We evaluate borrowers’ current and forecasted future cash flows, their ability and willingness to make current contractual or proposed modified payments, the value of the underlying collateral (if applicable), the possibility of obtaining additional security or guarantees, and the potential costs related to a repossession or foreclosure and the subsequent sale of the collateral. TDRs are classified as either accrual or nonaccrual loans. A loan on nonaccrual and restructured as a TDR will remain on nonaccrual status until the borrower has proven the ability to perform under the modified structure for a minimum of six months, and there is evidence that such payments can and are likely to continue as agreed. Performance prior to the restructuring, or significant events that coincide with the restructuring, are included in assessing whether the borrower can meet the new terms and may result in the loan being returned to accrual at the time of restructuring or after a shorter performance period. If the borrower’s ability to meet the revised payment schedule is uncertain, the loan remains classified as a nonaccrual loan. A TDR loan that specifies an interest rate that at the time of the restructuring is greater than or equal to the rate the bank is willing to accept for a new loan with comparable risk may not be reported as a TDR or an impaired loan in the calendar years subsequent to the restructuring if it is in compliance with its modified terms.

Derivative Instruments And Hedging Activities	6 Months Ended

Summary of Derivative Instruments [Abstract]
Derivative Instruments And Hedging Activities	DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES Objectives Our objectives in using derivatives are to add stability to interest income or expense, to modify the duration of specific assets or liabilities as we consider advisable, to manage exposure to interest rate movements or other identified risks, and/or to directly offset derivatives sold to our customers. To accomplish these objectives, we use interest rate swaps as part of our cash flow hedging strategy. These derivatives are used to hedge the variable cash flows associated with designated commercial loans. Interest rate swap agreements designated as cash flow hedges involve the receipt of fixed-rate amounts in exchange for variable rate payments over the life of the agreements without exchange of the underlying principal amount. Derivatives not designated as accounting hedges, including basis swap agreements, are not speculative and are used to economically manage our exposure to interest rate movements and other identified risks, but do not meet the strict hedge accounting requirements. Accounting We record all derivatives on the balance sheet at fair value. Note 10 discusses the process to estimate fair value for derivatives. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and the resulting designation. Derivatives used to hedge the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives used to hedge the exposure to variability in expected cash flows, or other types of forecasted transactions, are considered cash flow hedges. For derivatives designated as fair value hedges, changes in the fair value of the derivative are recognized in earnings together with changes in the fair value of the related hedged item. The net amount, if any, representing hedge ineffectiveness, is reflected in earnings. In previous years, we used fair value hedges to manage interest rate exposure to certain long-term debt. These hedges have been terminated and their remaining balances are being amortized into earnings, as discussed subsequently. For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivative are recorded in OCI and recognized in earnings when the hedged transaction affects earnings. The ineffective portion of changes in the fair value of cash flow hedges is recognized directly in earnings. No derivatives have been designated for hedges of investments in foreign operations. We assess the effectiveness of each hedging relationship by comparing the changes in fair value or cash flows on the derivative hedging instrument with the changes in fair value or cash flows on the designated hedged item or transaction. For derivatives not designated as accounting hedges, changes in fair value are recognized in earnings. The remaining balances of any derivative instruments terminated prior to maturity, including amounts in accumulated other comprehensive income (“AOCI”) for swap hedges, are accreted or amortized to interest income or expense over the period to their previously stated maturity dates. Amounts in AOCI are reclassified to interest income as interest is earned on variable rate loans and as amounts for terminated hedges are accreted or amortized to earnings. For the 12 months following June 30, 2015 , we estimate that an additional $8.7 million will be reclassified. Collateral and Credit Risk Exposure to credit risk arises from the possibility of nonperformance by counterparties. Financial institutions which are well capitalized and well established are the counterparties for those derivatives entered into for asset liability management and to offset derivatives sold to our customers. The Company reduces its counterparty exposure for derivative contracts by centrally clearing all eligible derivatives. For those derivatives that are not centrally cleared, the counterparties are typically financial institutions or customers of the Company. For those that are financial institutions, we manage our credit exposure through the use of a Credit Support Annex (“CSA”) to International Swaps and Derivative Association (“ISDA”) master agreements. Eligible collateral types are documented by the CSA and are controlled under the Company’s general credit policies and are typically monitored on a daily basis. A valuation haircut policy reflects the fact that collateral may fall in value between the date the collateral is called and the date of liquidation or enforcement. In practice, all of the Company’s collateral held as credit risk mitigation under a CSA is cash. We offer interest rate swaps to our customers to assist them in managing their exposure to changing interest rates. Upon issuance, all of these customer swaps are immediately offset through matching derivative contracts, such that the Company minimizes its interest rate risk exposure resulting from such transactions. Most of these customers do not have the capability for centralized clearing. Therefore we manage the credit risk through loan underwriting which includes a credit risk exposure formula for the swap, the same collateral and guarantee protection applicable to the loan and credit approvals, limits, and monitoring procedures. Fee income from customer swaps is included in other service charges, commissions and fees. No significant losses on derivative instruments have occurred as a result of counterparty nonperformance. Nevertheless, the related credit risk is considered and measured when and where appropriate. See Note 6 for further discussion of our underwriting, collateral requirements, and other procedures used to address credit risk. Our derivative contracts require us to pledge collateral for derivatives that are in a net liability position at a given balance sheet date. Certain of these derivative contracts contain credit-risk-related contingent features that include the requirement to maintain a minimum debt credit rating. We may be required to pledge additional collateral if a credit-risk-related feature were triggered, such as a downgrade of our credit rating. However, in past situations, not all counterparties have demanded that additional collateral be pledged when provided for under their contracts. At June 30, 2015 , the fair value of our derivative liabilities was $60.2 million , for which we were required to pledge cash collateral of approximately $46.3 million in the normal course of business. If our credit rating were downgraded one notch by either Standard & Poor’s or Moody’s at June 30, 2015 , the additional amount of collateral we could be required to pledge is approximately $1.7 million . As a result of the Dodd-Frank Act, all newly eligible derivatives entered into are cleared through a central clearinghouse. Derivatives that are centrally cleared do not have credit-risk-related features that require additional collateral if our credit rating were downgraded. Derivative Amounts Selected information with respect to notional amounts and recorded gross fair values at June 30, 2015 and December 31, 2014 , and the related gain (loss) of derivative instruments for the three and six months ended June 30, 2015 and 2014 is summarized as follows: June 30, 2015 December 31, 2014 Notional amount Fair value Notional amount Fair value (In thousands) Other assets Other liabilities Other assets Other liabilities Derivatives designated as hedging instruments Cash flow hedges: Interest rate swaps $ 737,500 $ 3,379 $ 398 $ 275,000 $ 1,508 $ 123 Total derivatives designated as hedging instruments 737,500 3,379 398 275,000 1,508 123 Derivatives not designated as hedging instruments Interest rate swaps for customers 2 2,984,909 43,968 45,598 2,770,052 48,287 50,669 Foreign exchange 315,300 16,615 14,249 443,721 16,625 15,272 Total derivatives not designated as hedging instruments 3,300,209 60,583 59,847 3,213,773 64,912 65,941 Total derivatives $ 4,037,709 $ 63,962 $ 60,245 $ 3,488,773 $ 66,420 $ 66,064 Three Months Ended June 30, 2015 Six Months Ended June 30, 2015 Amount of derivative gain (loss) recognized/reclassified (In thousands) OCI Reclassified 3 Noninterest income (expense) Offset to interest expense OCI Reclassified from AOCI to interest income 3 Noninterest income (expense) Offset to interest expense Derivatives designated as hedging instruments Asset derivatives Cash flow hedges 1 : Interest rate swaps $ (424 ) $ 1,218 $ 3,829 $ 2,234 (424 ) 1,218 3,829 2,234 Liability derivatives Fair value hedges: Terminated swaps on long-term debt $ 465 $ 933 Total derivatives designated as hedging instruments (424 ) 1,218 465 3,829 2,234 933 Derivatives not designated as hedging instruments Interest rate swaps for customers 2 $ 3,873 $ 4,390 Futures contracts — 1 Foreign exchange 1,697 4,432 Total derivatives not designated as hedging instruments 5,570 8,823 Total derivatives $ (424 ) $ 1,218 $ 5,570 $ 465 $ 3,829 $ 2,234 $ 8,823 $ 933 Three Months Ended June 30, 2014 Six Months Ended June 30, 2014 Amount of derivative gain (loss) recognized/reclassified (In thousands) OCI Reclassified 3 Noninterest income (expense) Offset to interest expense OCI Reclassified from AOCI to interest income 3 Noninterest income (expense) Offset to interest expense Derivatives designated as hedging instruments Asset derivatives Cash flow hedges 1 : Interest rate swaps $ 1,988 $ 577 $ 2,526 $ 928 1,988 577 2,526 928 Liability derivatives Fair value hedges: Terminated swaps on long-term debt $ 608 $ 1,326 Total derivatives designated as hedging instruments 1,988 577 608 2,526 928 1,326 Derivatives not designated as hedging instruments Interest rate swaps $ 348 $ 354 Interest rate swaps for customers 2 (377 ) (926 ) Foreign exchange 1,998 3,709 Total return swap (467 ) (7,894 ) Total derivatives not designated as hedging instruments 1,502 (4,757 ) Total derivatives $ 1,988 $ 577 $ 1,502 $ 608 $ 2,526 $ 928 $ (4,757 ) $ 1,326 Note: These schedules are not intended to present at any given time the Company’s long/short position with respect to its derivative contracts. 1 Amounts recognized in OCI and reclassified from AOCI represent the effective portion of the derivative gain. 2 Notional amounts include both the customer swaps and the offsetting derivative contracts. 3 Amounts for the three and six months ended June 30 , of $1.2 million and $2.2 million in 2015 , and $0.6 million and $0.9 million in 2014 , respectively, are the amounts of reclassification to earnings from AOCI presented in Note 8. At June 30, the fair values of derivative assets and liabilities were reduced by net credit valuation adjustments of $1.7 million and $0.1 million in 2015 , and $1.9 million and $0.5 million in 2014 , respectively. These adjustments are required to reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk.

During the three months ended June 30, 2015 , we redeemed $3.1 million of trust preferred securities and the entire $22 million of FHLB advances; the FHLB redemption resulted in debt extinguishment cost of $2.4 million . Basel III Capital Framework Effective January 1, 2015, we adopted the new Basel III capital framework that was issued by the Federal Reserve for U.S. banking organizations. We adopted the new capital rules on a 2015 phase-in basis and will adopt the fully phased-in requirements effective January 1, 2019. During the first quarter, we made the “opt-out” election with respect to the regulatory capital treatment of AOCI under the Basel III framework. Among other things, the new rules revise capital adequacy guidelines and the regulatory framework for prompt corrective action, and they modify specified quantitative measures of our assets, liabilities, and capital. The impact of these new rules will require the Company to maintain capital in excess of current “well-capitalized” regulatory standards.

Income Taxes

Income Taxes	6 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES The effective income tax rate for the three and six months ended June 30, 2015 and 2014 was lower than the blended statutory rate of 38.25% primarily because of an increase in the proportion of nontaxable items relative to pretax income. Net deferred tax assets were approximately $202 million at June 30, 2015 and $224 million at December 31, 2014 . We evaluate deferred tax assets on a regular basis to determine whether an additional valuation allowance is required. Based on this evaluation, and considering the weight of the positive evidence compared to the negative evidence, we have concluded that an additional valuation allowance is not required as of June 30, 2015 .

Fair Value

Fair Value Disclosures [Abstract]
Fair Value	Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. To measure fair value, a hierarchy has been established that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs. This hierarchy uses three levels of inputs to measure the fair value of assets and liabilities as follows: Level 1 – Quoted prices in active markets for identical assets or liabilities in active markets that the Company has the ability to access; Level 2 – Observable inputs other than Level 1 including quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in less active markets, observable inputs other than quoted prices that are used in the valuation of an asset or liability, and inputs that are derived principally from or corroborated by observable market data by correlation or other means; and Level 3 – Unobservable inputs supported by little or no market activity for financial instruments whose value is determined by pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. The level in the fair value hierarchy within which the fair value measurement is classified is determined based on the lowest level input that is significant to the fair value measure in its entirety. Market activity is presumed to be orderly in the absence of evidence of forced or disorderly sales, although such sales may still be indicative of fair value. Applicable accounting guidance precludes the use of blockage factors or liquidity adjustments due to the quantity of securities held by an entity. We use fair value to measure certain assets and liabilities on a recurring basis when fair value is the primary measure for accounting. Fair value is used on a nonrecurring basis to measure certain assets when adjusting carrying values, such as the application of lower of cost or fair value accounting, including recognition of impairment on assets. Fair value is also used when providing required disclosures for certain financial instruments. Fair Value Policies and Procedures We have various policies, processes and controls in place to ensure that fair values are reasonably developed, reviewed and approved for use. These include a Securities Valuation Committee (“SVC”) comprised of executive management appointed by the Board of Directors. The SVC reviews and approves on a quarterly basis the key components of fair value estimation, including critical valuation assumptions for Level 3 modeling. A Model Risk Management Group conducts model validations, including internal models, and sets policies and procedures for revalidation, including the timing of revalidation. Third Party Service Providers We use a third party pricing service to provide pricing for approximately 91% of our AFS Level 2 securities. Fair values for other AFS Level 2 and for Level 3 securities generally use certain inputs corroborated by market data and include standard form discounted cash flow modeling. For Level 2 securities, the third party pricing service provides documentation on an ongoing basis that presents market corroborative data, including detail pricing information and market reference data. The documentation includes benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data, including information from the vendor trading platform. We review, test and validate this information as appropriate. Absent observable trade data, we do not adjust prices from our third party sources. The following describes the hierarchy designations, valuation methodologies, and key inputs to measure fair value on a recurring basis for designated financial instruments: Available-for-Sale U.S. Treasury, Agencies and Corporations U.S. Treasury securities are measured under Level 1 using quoted market prices when available. U.S. agencies and corporations are measured under Level 2 generally using the previously discussed third party pricing service. Municipal Securities Municipal securities are measured under Level 2 generally using the third party pricing service. Valuation inputs include Baa municipal curves, as well as FHLB and London Interbank Offered Rate (“LIBOR”) swap curves. Mutual Funds and Other Mutual funds and other securities are measured under Level 1 or Level 2. For Level 1, quoted market prices are used which may include net asset values or their equivalents. Level 2 valuations generally use quoted prices for similar securities. Trading Account Securities in the trading account are measured under Level 1 using quoted market prices. If not available, quoted prices under Level 2 for similar securities are used. Bank-Owned Life Insurance Bank-owned life insurance (“BOLI”) is measured under Level 2 according to cash surrender values (“CSVs”) of the insurance policies that are provided by a third party service. Nearly all policies are general account policies with CSVs based on the Company’s claims on the assets of the insurance companies. The insurances companies’ investments include predominantly fixed income securities consisting of investment-grade corporate bonds and various types of mortgage instruments. Management regularly reviews its BOLI investment performance, including concentrations among insurance providers. Private Equity Investments Private equity investments are measured under Level 3. The Equity Investments Committee, consisting of executives familiar with the investments, reviews periodic financial information, including audited financial statements when available. Certain analytics may be employed that include current and projected financial performance, recent financing activities, economic and market conditions, market comparables, market liquidity, sales restrictions, and other factors. The amount of unfunded commitments to invest is disclosed in Note 11. Certain restrictions apply for the redemption of these investments and certain investments are prohibited by the Volcker Rule. See discussions in Notes 5 and 11. Agriculture Loan Servicing This asset results from our servicing of agriculture loans approved and funded by FAMC. We provide this servicing under an agreement with Farmer Mac for loans they own. The asset’s fair value represents our projection of the present value of future cash flows measured under Level 3 using discounted cash flow methodologies. Interest-Only Strips Interest-only strips are created as a by-product of the securitization process. When the guaranteed portions of SBA 7(a) loans are pooled, interest-only strips may be created in the pooling process. The asset’s fair value represents our projection of the present value of future cash flows measured under Level 3 using discounted cash flow methodologies. Deferred Compensation Plan Assets and Obligations Invested assets in the deferred compensation plan consist of shares of registered investment companies. These mutual funds are valued under Level 1 at quoted market prices, which represents the NAV of shares held by the plan at the end of the period. Derivatives Derivatives are measured according to their classification as either exchange-traded or over-the-counter (“OTC”). Exchange-traded derivatives consist of foreign currency exchange contracts measured under Level 1 because they are traded in active markets. OTC derivatives, including those for customers, consist of interest rate swaps and options. These derivatives are measured under Level 2 using third party services. Observable market inputs include yield curves (the LIBOR swap curve and relevant overnight index swap curves), foreign exchange rates, commodity prices, option volatilities, counterparty credit risk, and other related data. Credit valuation adjustments are required to reflect nonperformance risk for both the Company and the respective counterparty. These adjustments are determined generally by applying a credit spread to the total expected exposure of the derivative. Securities Sold, Not Yet Purchased Securities sold, not yet purchased, included in “Federal funds and other short-term borrowings” on the balance sheet, are measured under Level 1 using quoted market prices. If not available, quoted prices under Level 2 for similar securities are used.

Previous to their sale in these periods, we recognized impairment on these properties of $0.3 million and $0.4 million in 2015 and $0.3 million and $0.5 million in 2014 . Private equity investments carried at cost were measured at fair value for impairment purposes according to the methodology previously discussed for these investments. Amounts of private equity investments carried at cost were $29.6 million at June 30, 2015 and $39.1 million at December 31, 2014 . Amounts of other noninterest-bearing investments carried at cost were $244.1 million at June 30, 2015 and $250.7 million at December 31, 2014 , which were comprised of Federal Reserve, Federal Home Loan Bank, and Farmer Mac stock. Impaired (or nonperforming) loans that are collateral-dependent were measured at fair value based on the fair value of the collateral. OREO was measured initially at fair value based on property appraisals at the time of transfer and subsequently at the lower of cost or fair value. Measurement of fair value for collateral-dependent loans and OREO was based on third party appraisals that utilize one or more valuation techniques (income, market and/or cost approaches). Any adjustments to calculated fair value were made based on recently completed and validated third party appraisals, third party appraisal services, automated valuation services, or our informed judgment. Evaluations were made to determine that the appraisal process met the relevant concepts and requirements of applicable accounting guidance. Automated valuation services may be used primarily for residential properties when values from any of the previous methods were not available within 90 days of the balance sheet date. These services use models based on market, economic, and demographic values. The use of these models has only occurred in a very few instances and the related property valuations have not been significant to consider disclosure under Level 3 rather than Level 2. Impaired loans not collateral-dependent were measured at fair valued based on the present value of future cash flows discounted at the expected coupon rates over the lives of the loans. Because the loans were not discounted at market interest rates, the valuations do not represent fair value and have been excluded from the nonrecurring fair value balance in the preceding schedules. Fair Value of Certain Financial Instruments Following is a summary of the carrying values and estimated fair values of certain financial instruments: June 30, 2015 December 31, 2014 (In thousands) Carrying value Estimated fair value Level Carrying value Estimated fair value Level Financial assets: HTM investment securities $ 570,869 $ 578,327 3 $ 647,252 $ 677,196 3 Loans and leases (including loans held for sale), net of allowance 39,567,057 39,296,460 3 39,591,499 39,426,498 3 Financial liabilities: Time deposits 2,263,146 2,265,320 2 2,406,924 2,408,550 2 Foreign deposits 372,106 372,069 2 328,391 328,447 2 Long-term debt (less fair value hedges) 1,050,367 1,091,173 2 1,090,778 1,159,287 2 This summary excludes financial assets and liabilities for which carrying value approximates fair value. For financial assets, these include cash and due from banks and money market investments. For financial liabilities, these include demand, savings and money market deposits, and federal funds purchased and security repurchase agreements. The estimated fair value of demand, savings and money market deposits is the amount payable on demand at the reporting date. Carrying value is used because the accounts have no stated maturity and the customer has the ability to withdraw funds immediately. Also excluded from the summary are financial instruments recorded at fair value on a recurring basis, as previously described. HTM investment securities primarily consist of municipal securities. They were measured at fair value according to the methodologies previously discussed for these investment types. Loans are measured at fair value according to their status as nonimpaired or impaired. For nonimpaired loans, fair value is estimated by discounting future cash flows using the LIBOR yield curve adjusted by a factor which reflects the credit and interest rate risk inherent in the loan. These future cash flows are then reduced by the estimated “life-of-the-loan” aggregate credit losses in the loan portfolio. These adjustments for lifetime future credit losses are derived from the methods used to estimate the ALLL for our loan portfolio and are adjusted quarterly as necessary to reflect the most recent loss experience. Impaired loans are already considered to be held at fair value, except those whose fair value is determined by discounting cash flows, as discussed previously. See Impaired Loans in Note 6 for details on the impairment measurement method for impaired loans. Loans, other than those held for sale, are not normally purchased and sold by the Company, and there are no active trading markets for most of this portfolio. Time and foreign deposits, and any other short-term borrowings, are measured at fair value by discounting future cash flows using the LIBOR yield curve to the given maturity dates. Long-term debt is measured at fair value based on actual market trades (i.e., an asset value) when available, or discounting cash flows to maturity using the LIBOR yield curve adjusted for credit spreads. These fair value disclosures represent our best estimates based on relevant market information and information about the financial instruments. Fair value estimates are based on judgments regarding current economic conditions, future expected loss experience, risk characteristics of the various instruments, and other factors. These estimates are subjective in nature, involve uncertainties and matters of significant judgment, and cannot be determined with precision. Changes in these methodologies and assumptions could significantly affect the estimates.

Guarantees, Commitments And Contingencies [Abstract]
Guarantees, Commitments And Contingencies	COMMITMENTS, GUARANTEES AND CONTINGENT LIABILITIES Commitments and Guarantees Contractual amounts of off-balance sheet financial instruments used to meet the financing needs of our customers are as follows: (In thousands) June 30, December 31, Net unfunded commitments to extend credit 1 $ 16,678,282 $ 16,658,757 Standby letters of credit: Financial 677,693 745,895 Performance 193,710 183,482 Commercial letters of credit 37,674 32,144 Total unfunded lending commitments $ 17,587,359 $ 17,620,278 1 Net of participations The Company’s 2014 Annual Report on Form 10-K contains further information about these commitments and guarantees including their terms and collateral requirements. At June 30, 2015 , the Company had recorded approximately $14.7 million as a liability for the guarantees associated with the standby letters of credit, which consisted of $11.9 million attributable to the RULC and $2.8 million of deferred commitment fees. At June 30, 2015 , the Parent has guaranteed $15.0 million of debt of affiliated trusts issuing trust preferred securities. At June 30, 2015 , we had unfunded commitments for private equity investments of approximately $48 million . These obligations have no stated maturity. Certain PEIs related to these commitments are prohibited by the Volcker Rule. See related discussions about these investments in Notes 5 and 10. Legal Matters We are subject to litigation in court and arbitral proceedings, as well as proceedings, investigations, examinations and other actions brought or considered by governmental and self-regulatory agencies. Litigation may relate to lending, deposit and other customer relationships, vendor and contractual issues, employee matters, intellectual property matters, personal injuries and torts, regulatory and legal compliance, and other matters. While most matters relate to individual claims, we are also subject to putative class action claims and similar broader claims. Proceedings, investigations, examinations and other actions brought or considered by governmental and self-regulatory agencies may relate to our banking, investment advisory, trust, securities, and other products and services; our customers’ involvement in money laundering, fraud, securities violations and other illicit activities or our policies and practices relating to such customer activities; and our compliance with the broad range of banking, securities and other laws and regulations applicable to us. At any given time, we may be in the process of responding to subpoenas, requests for documents, data and testimony relating to such matters and engaging in discussions to resolve the matters. As of June 30, 2015 , we were subject to the following material litigation and governmental inquiries: • a class action case, Reyes v. Zions First National Bank, et. al., which was brought in the United States District Court for the Eastern District of Pennsylvania in early 2010. This case relates to our banking relationships with customers that allegedly engaged in wrongful telemarketing practices. The plaintiff is seeking a trebled monetary award under the federal RICO Act. In the third quarter of 2013, the District Court denied the plaintiff’s motion for class certification in the Reyes case. The plaintiff appealed the District Court decision to the Third Circuit Court of Appeals. The Third Circuit had not ruled on the appeals as of August 2015. • a governmental inquiry into possible money laundering activities of a customer of one of our subsidiary banks and the anti-money laundering practices of that bank (conducted by the United States Attorney’s Office for the Southern District of New York). Our first contact with the United States Attorney’s Office relating to this matter occurred in early 2012. We are unclear about the status of this inquiry. • a governmental inquiry into the practices of our subsidiary, Zions Bank; our former subsidiary, NetDeposit, LLC; and possibly other of our affiliates relating primarily to payment processing for allegedly fraudulent telemarketers and other customer types (conducted by the Department of Justice). This inquiry has been directed towards the banking industry generally, including numerous banks unrelated to us, and has led to a number of enforcement actions. Our first contact with the Department of Justice relating to this matter occurred in early 2013. We are unclear about the status of the inquiry as it relates to us. At least quarterly, we review outstanding and new legal matters, utilizing then available information. In accordance with applicable accounting guidance, if we determine that a loss from a matter is probable and the amount of the loss can be reasonably estimated, we establish an accrual for the loss. In the absence of such a determination, no accrual is made. Once established, accruals are adjusted to reflect developments relating to the matters. In our review, we also assess whether we can determine the range of reasonably possible losses for significant matters in which we are unable to determine that the likelihood of a loss is remote. Because of the difficulty of predicting the outcome of legal matters, discussed subsequently, we are able to meaningfully estimate such a range only for a limited number of matters. Based on information available as of June 30, 2015 , we estimated the aggregate range of reasonably possible losses for those matters to be from $0 million to roughly $50 million in excess of amounts accrued. The matters underlying the estimated range will change from time to time, and actual results may vary significantly from this estimate. Those matters for which an estimate is not possible are not included within this estimated range and, therefore, this estimated range does not represent our maximum loss exposure. Based on our current knowledge, we believe that our current estimated liability for litigation and other legal actions and claims, reflected in our accruals and determined in accordance with applicable accounting guidance, is adequate and that liabilities in excess of the amounts currently accrued, if any, arising from litigation and other legal actions and claims for which an estimate as previously described is possible, will not have a material impact on our financial condition, results of operations, or cash flows. However, in light of the significant uncertainties involved in these matters, and the very large or indeterminate damages sought in some of these matters, an adverse outcome in one or more of these matters could be material to our financial condition, results of operations, or cash flows for any given reporting period. Any estimate or determination relating to the future resolution of litigation, arbitration, governmental or self-regulatory examinations, investigations or actions or similar matters is inherently uncertain and involves significant judgment. This is particularly true in the early stages of a legal matter, when legal issues and facts have not been well articulated, reviewed, analyzed, and vetted through discovery, preparation for trial or hearings, substantive and productive mediation or settlement discussions, or other actions. It is also particularly true with respect to class action and similar claims involving multiple defendants, matters with complex procedural requirements or substantive issues or novel legal theories, and examinations, investigations and other actions conducted or brought by governmental and self-regulatory agencies, in which the normal adjudicative process is not applicable. Accordingly, we usually are unable to determine whether a favorable or unfavorable outcome is remote, reasonably likely, or probable, or to estimate the amount or range of a probable or reasonably likely loss, until relatively late in the course of a legal matter, sometimes not until a number of years have elapsed. Accordingly, our judgments and estimates relating to claims will change from time to time in light of developments and actual outcomes will differ from our estimates. These differences may be material.

Operating Segment Information [Abstract]
Operating Segment Information	. OPERATING SEGMENT INFORMATION We manage our operations and prepare management reports and other information with a primary focus on geographical area. As of June 30, 2015 , we operate seven community/regional banks in distinct geographical areas. Performance assessment and resource allocation are based upon this geographical structure. Zions Bank operates 101 branches in Utah, 25 branches in Idaho, and one branch in Wyoming. Amegy operates 79 branches in Texas. CB&T operates 94 branches in California. NBAZ operates 66 branches in Arizona. NSB operates 50 branches in Nevada. Vectra operates 36 branches in Colorado and one branch in New Mexico. TCBW operates one branch in Washington and one branch in Oregon. Effective April 1, 2015, TCBO was merged into TCBW. Note 1 discusses the upcoming consolidation of the seven bank charters into one bank charter. When completed, this consolidation will affect the presentation of segment reporting, although certain geographical information will continue. The operating segment identified as “Other” includes the Parent, Zions Management Services Company (“ZMSC”), certain nonbank financial service subsidiaries, and eliminations of transactions between segments. The Parent’s operations are significant to the Other segment. Net interest income is substantially affected by the Parent’s interest on long-term debt. ZMSC provides internal technology and operational services to affiliated operating businesses of the Company. ZMSC charges most of its costs to the affiliates on an approximate break-even basis. The accounting policies of the individual operating segments are the same as those of the Company.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	BASIS OF PRESENTATION The accompanying unaudited consolidated financial statements of Zions Bancorporation (“the Parent”) and its majority-owned subsidiaries (collectively “the Company,” “Zions,” “we,” “our,” “us”) have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. References to GAAP, including standards promulgated by the Financial Accounting Standards Board (“FASB”), are made according to sections of the Accounting Standards Codification (“ASC”) and to Accounting Standards Updates (“ASU”), which include consensus issues of the Emerging Issues Task Force (“EITF”). In certain cases, ASUs are issued jointly with International Financial Reporting Standards (“IFRS”). Certain prior period amounts have been reclassified to conform with the current period presentation. These reclassifications did not affect net income. Operating results for the three and six months ended June 30, 2015 and 2014 are not necessarily indicative of the results that may be expected in future periods. The consolidated balance sheet at December 31, 2014 is from the audited financial statements at that date, but does not include all of the information and footnotes required by GAAP for complete financial statements. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s 2014 Annual Report on Form 10-K. The Company provides a full range of banking and related services through subsidiary banks in 11 Western and Southwestern states as follows: Zions First National Bank (“Zions Bank”), in Utah, Idaho and Wyoming; Amegy Corporation (“Amegy”) and its subsidiary, Amegy Bank, in Texas; California Bank & Trust (“CB&T”); National Bank of Arizona (“NBAZ”); Nevada State Bank (“NSB”); Vectra Bank Colorado (“Vectra”), in Colorado and New Mexico; and The Commerce Bank of Washington (“TCBW”), in Washington and Oregon. Effective April 1, 2015, The Commerce Bank of Oregon (“TCBO”) was merged into TCBW. The Parent and its subsidiary banks also own and operate certain nonbank subsidiaries that engage in financial services. On June 1, 2015, the Company announced certain efficiency and restructuring initiatives that included, among other things, the consolidation of its seven bank charters into one bank charter. This change is subject to regulatory approval and is currently expected to be completed within the next 6 to 12 months.

Segment Reporting Information [Line Items]
Operating Segment Information	. OPERATING SEGMENT INFORMATION We manage our operations and prepare management reports and other information with a primary focus on geographical area. As of June 30, 2015 , we operate seven community/regional banks in distinct geographical areas. Performance assessment and resource allocation are based upon this geographical structure. Zions Bank operates 101 branches in Utah, 25 branches in Idaho, and one branch in Wyoming. Amegy operates 79 branches in Texas. CB&T operates 94 branches in California. NBAZ operates 66 branches in Arizona. NSB operates 50 branches in Nevada. Vectra operates 36 branches in Colorado and one branch in New Mexico. TCBW operates one branch in Washington and one branch in Oregon. Effective April 1, 2015, TCBO was merged into TCBW. Note 1 discusses the upcoming consolidation of the seven bank charters into one bank charter. When completed, this consolidation will affect the presentation of segment reporting, although certain geographical information will continue. The operating segment identified as “Other” includes the Parent, Zions Management Services Company (“ZMSC”), certain nonbank financial service subsidiaries, and eliminations of transactions between segments. The Parent’s operations are significant to the Other segment. Net interest income is substantially affected by the Parent’s interest on long-term debt. ZMSC provides internal technology and operational services to affiliated operating businesses of the Company. ZMSC charges most of its costs to the affiliates on an approximate break-even basis. The accounting policies of the individual operating segments are the same as those of the Company. Transactions between operating segments are primarily conducted at fair value, resulting in profits that are eliminated for reporting consolidated results of operations.
