Equity Method Investment [Abstract]
Equity Method Investment	Note 3. Equity method investment Upon its initial investment in BHG, Pinnacle Bank accounted for this investment pursuant to the equity method for unconsolidated subsidiaries and recognized its interest in BHG's profits and losses in noninterest income with corresponding adjustments to the BHG investment account. Because BHG has been determined to be a voting interest entity of which Pinnacle Financial and Pinnacle Bank control less than a majority of the board seats following the closing of the additional investment in March 2016, this investment does not require consolidation and will continue to be accounted for pursuant to the equity method of accounting. PINNACLE FINANCIAL PARTNERS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) The equity method of accounting requires that embedded goodwill and intangibles should be identified, tested for impairment and amortized over their useful life within the equity method investment line of the balance sheet. Amortization expense associated with BHG's customer list and data processing capabilities is netted within income from equity method investments. At March 31, 2016, Pinnacle Financial has recorded estimated embedded goodwill of $139.1 million and $16.0 million, net of related amortization, for technology, trade name and customer relationship intangibles compared to $50.6 million and $5.1 million, respectively, as of December 31, 2015. Pinnacle has not yet completed the purchase accounting for the subsequent investment in BHG and the estimates of equity embedded goodwill and intangible assets are considered preliminary as of March 31, 2016. During the first quarter of 2016, Pinnacle Financial recorded earnings of $5.5 million, net of approximately $370,000 in intangible amortization expense compared to recorded earnings of $3.6 million, net of approximately $400,000 in intangible amortization expense for the three months ended March 31, 2015. Earnings from BHG are included in Pinnacle Financial's consolidated tax return. Profit from intercompany transactions are eliminated as a part of consolidation. As part of ongoing business transacted with BHG, Pinnacle Bank purchased loans from BHG totaling $2.2 million during the year ended December 31, 2015. No loans were purchased for the period ended March 31, 2016. A summary of BHG's financial position as of March 31, 2016 and December 31, 2015 and results of operations for the three months ended March 31, 2016 and 2015, were as follows (in thousands): Banker's Healthcare Group ($ in thousands) As of March 31, 2016 December 31, 2015 Assets $ 208,244 220,578 Liabilities 141,445 137,147 Membership interests 66,799 83,431 Total liabilities and membership $ 208,244 220,578 For the three months ended March 31, 2016 March 31, 2015 Revenues $ 31,288 27,045 Net income, pre-tax $ 12,154 14,384

At March 31, 2016 repurchase agreements comprised of secured borrowings totaled $62.8 million and were secured by $ 62.8 million of pledged U.S. government agency securities , municipal securities, asset backed securities, and corporate debentures. The fair value of securities pledged to secure repurchase agreements may decline. As the fair value of securities pledged to secure repurchase agreements may decline, the company regularly evaluates its need to pledge additional securities to remain adequately secured. The amortized cost and fair value of debt securities as of March 31, 2016 by contractual maturity are shown below. Actual maturities may differ from contractual maturities of mortgage- and asset-backed securities since the mortgages and assets underlying the securities may be called or prepaid with or without penalty.

As such, it is possible that a security had a market value that exceeded its amortized cost on other days during the past twelve-month periods ended March 31, 2016 and December 31, 2015, but is in the "Investments with an Unrealized Loss of less than 12 months" category above. As shown in the tables above, at March 31, 2016, Pinnacle Financial had approximately $3.7 million in unrealized losses on $303.3 million of securities. The unrealized losses associated with these investment securities are driven by changes in interest rates and the unrealized loss is recorded as a component of equity. These securities will continue to be monitored as a part of our ongoing impairment analysis, but are expected to perform even if the rating agencies reduce the credit rating of the bond issuers. Management evaluates the financial performance of the issuers on a quarterly basis to determine if it is probable that the issuers can make all contractual principal and interest payments. If a shortfall in future cash flows is identified, a credit loss will be deemed to have occurred and will be recognized as a charge to earnings and a new cost basis for the security will be established. Because Pinnacle Financial currently does not intend to sell those securities that have an unrealized loss at March 31, 2016, and it is not more-likely-than-not that Pinnacle Financial will be required to sell the securities before recovery of their amortized cost bases, which may be maturity, Pinnacle Financial does not consider these securities to be other-than-temporarily impaired at March 31, 2016. Periodically, available-for-sale securities may be sold or the composition of the portfolio realigned to improve yields, quality or marketability, or to implement changes in investment or asset/liability strategy, including maintaining collateral requirements and raising funds for liquidity purposes. Additionally, if an available-for-sale security loses its investment grade or tax-exempt status, the underlying credit support is terminated or collection otherwise becomes uncertain based on factors known to management, Pinnacle Financial will consider selling the security, but will review each security on a case-by-case basis as these factors become known. The carrying values of Pinnacle Financial's investment securities could decline in the future if the financial condition of issuers deteriorates and management determines it is probable that Pinnacle Financial will not recover the entire amortized cost bases of the securities. As a result, there is a risk that other-than-temporary impairment charges may occur in the future. Additionally, there is a risk that other-than-temporary impairment charges may occur in the future if management's intention to hold these securities to maturity and or recovery changes.

Loans and Allowance for Loan Losses [Abstract]
Loans and Allowance for Loan Losses	Note 5. Loans and Allowance for Loan Losses For financial reporting purposes, Pinnacle Financial classifies its loan portfolio based on the underlying collateral utilized to secure each loan. This classification is consistent with those utilized in the Quarterly Report of Condition and Income filed with the Federal Deposit Insurance Corporation (FDIC). Pinnacle Financial uses five loan categories: commercial real estate mortgage, consumer real estate mortgage, construction and land development, commercial and industrial, and consumer and other. · Commercial real-estate mortgage loans · Consumer real-estate mortgage loans · Construction and land development loans · Commercial and industrial loans · Consumer and other loans Commercial loans receive risk ratings assigned by a financial advisor and approved by a senior credit officer subject to validation by Pinnacle Financial's independent loan review department. Risk ratings are categorized as pass, special mention, substandard, substandard-nonaccrual or doubtful-nonaccrual. Pinnacle Financial believes that its categories follow those used by Pinnacle Bank's primary regulators. At March 31, 2016, approximately 74.55% of our loan portfolio was analyzed as a commercial loan type with a specifically assigned risk rating in the allowance for loan loss assessment. Consumer loans and small business loans are generally not assigned an individual risk rating but are evaluated as either accrual or nonaccrual based on the performance of the individual loans. However, certain consumer real-estate mortgage loans and certain consumer and other loans receive a specific risk rating due to the loan proceeds being used for commercial purposes even though the collateral may be of a consumer loan nature. Risk ratings are subject to continual review by a financial advisor and a senior credit officer. At least annually, our credit procedures require that every risk rated loan of $500,000 or more be subject to a formal credit risk review process by the assigned financial advisor. Each loan's risk rating is also subject to review by our independent loan review department, which reviews a substantial portion of our risk rated portfolio annually. Included in the coverage are independent loan reviews of loans in targeted higher-risk portfolio segments such as certain commercial and industrial loans, land loans and/or loan types in certain geographies. The following table presents our loan balances by primary loan classification and the amount within each risk rating category. Pass rated loans include all credits other than those included in special mention, substandard, substandard-nonaccrual and doubtful-nonaccrual which are defined as follows:  Special mention loans have 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 Pinnacle Financial's credit position at some future date.  Substandard loans are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified must have a well-defined weakness or weaknesses that jeopardize collection of the debt. Substandard loans are characterized by the distinct possibility that Pinnacle Financial will sustain some loss if the deficiencies are not corrected.  Substandard-nonaccrual loans are substandard loans that have been placed on nonaccrual status.  Doubtful-nonaccrual loans have all the characteristics of substandard-nonaccrual loans with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable.

This definition is believed to be substantially consistent with the standards established by Pinnacle Bank's primary regulators for loans classified as substandard, excluding the impact of nonaccrual loans and troubled debt restructurings. Potential problem loans, which are not included in nonaccrual loans, amounted to approximately $112.5 million at March 31, 2016, compared to $105.0 million at December 31, 2015.

Loans acquired with deteriorated credit quality are recorded pursuant to the provisions of ASC 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality The following table provides a rollforward of purchase credit impaired loans from December 31, 2015 through March 31, 2016 (in thousands): Gross Contractual Receivable Accretable Yield Nonaccretable Yield Carrying Value December 31, 2015 $ 16,274 $ - $ (4,143 ) $ 12,131 Year-to-date settlements (1,484 ) - 154 (1,330 ) Additional fundings 54 - - 54 March 31, 2016 $ 14,855 $ - $ (3,989 ) $ 10,855 These loans have been deemed to be collateral dependent and as such, no accretable yield has been recorded for these loans. At the date of acquisition, the Day 1 Fair Value represents the carrying value. The carrying value is adjusted for additional draws, pursuant to contractual arrangements, offset by loan paydowns. Year-to-date settlements include both loans that were charged-off as well as loans that were paid off, typically as a result of refinancings at other institutions. Impaired loans also include loans that Pinnacle Bank has elected to formally restructure due to the weakening credit status of a borrower. The restructuring may facilitate a repayment plan that seeks to minimize the potential losses that Pinnacle Bank may otherwise incur. If on nonaccrual status as of the date of restructuring, the loans are included in nonaccrual loans. Loans that have been restructured that were performing as of the restructure date and continue to perform in accordance with the restructured terms are reported separately as troubled debt restructurings. At both March 31, 2016 and December 31, 2015, there were $10.0 million and $8.1 million, respectively, of troubled debt restructurings that were performing as of their restructure date and which were accruing interest. These troubled debt restructurings are considered impaired loans pursuant to U.S. GAAP. Troubled commercial loans are restructured by specialists within our Special Assets Group, and all restructurings are approved by committees and credit officers separate and apart from the normal loan approval process. These specialists are charged with reducing Pinnacle Financial's overall risk and exposure to loss in the event of a restructuring by obtaining some or all of the following: improved documentation, additional guaranties, increase in curtailments, reduction in collateral release terms, additional collateral or other similar strategies.

The level of the allowance is based upon evaluation of the loan portfolio, current asset quality trends, known and inherent risks in the portfolio, adverse situations that may affect the borrowers' ability to repay (including the timing of future payment), the estimated value of any underlying collateral, composition of the loan portfolio, economic conditions, historical loss experience, industry and peer bank loan quality indications and other pertinent factors, including regulatory recommendations. The allowance for loan losses for purchased loans is calculated similarly to the method utilized for legacy Pinnacle Bank loans. Pinnacle Financial's accounting policy is to compare the computed allowance for loan losses for purchased loans to any remaining fair value adjustment. If the computed allowance is greater than the remaining fair value adjustment, the excess is added to the allowance for loan losses by a charge to the provision for loan losses. Pinnacle Financial analyzes its commercial loan portfolio to determine if a concentration of credit risk exists to any industry. Pinnacle Financial utilizes broadly accepted industry classification systems in order to classify borrowers into various industry classifications. Pinnacle Financial has a credit exposure (loans outstanding plus unfunded lines of credit) exceeding 25% of Pinnacle Bank's total risk-based capital to borrowers in the following industries at March 31, 2016 with the comparative exposures for December 31, 2015 (in thousands): at March 31, 2016 Outstanding Principal Balances Unfunded Commitments Total exposure Total Exposure at December 31, 2015 Lessors of nonresidential buildings $ 874,814 $ 232,748 $ 1,107,562 $ 1,078,211 Lessors of residential buildings 398,569 173,805 572,374 500,266 At March 31, 2016, Pinnacle Bank had granted loans and other extensions of credit amounting to approximately $10.5 million to current directors, executive officers, and their related entities, of which $7.4 million had been drawn upon. At December 31, 2015, Pinnacle Bank had granted loans and other extensions of credit amounting to approximately $14.5 million to directors, executive officers, and their related entities, of which approximately $11.4 million had been drawn upon. None of these loans to directors, executive officers, and their related entities were impaired at March 31, 2016 or December 31, 2015. PINNACLE FINANCIAL PARTNERS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) Residential Lending At March 31, 2016, Pinnacle Financial had approximately $35.4 million of mortgage loans held-for-sale compared to approximately $47.9 million at December 31, 2015. Total loan volumes sold during the three months ended March 31, 2016 were approximately $163.9 million compared to approximately $95.8 million for the three months ended ended March 31, 2015. During the three months ended March 31, 2016, Pinnacle Financial recognized $3.6 million in gains on the sale of these loans, net of commissions paid, compared to $1.9 million during the three months ended March 31, 2015. These mortgage loans held-for-sale are originated internally and are primarily to borrowers in Pinnacle Bank's geographic markets. These sales are typically on a mandatory basis to investors that follow conventional government sponsored entities (GSE) and the Department of Housing and Urban Development/U.S. Department of Veterans Affairs (HUD/VA) guidelines. Each purchaser has specific guidelines and criteria for sellers of loans, and the risk of credit loss with regard to the principal amount of the loans sold is generally transferred to the purchasers upon sale. While the loans are sold without recourse, the purchase agreements require Pinnacle Bank to make certain representations and warranties regarding the existence and sufficiency of file documentation and the absence of fraud by borrowers or other third parties such as appraisers in connection with obtaining the loan. If it is determined that the loans sold were in breach of these representations or warranties, Pinnacle Bank has obligations to either repurchase the loan for the unpaid principal balance and related investor fees or make the purchaser whole for the economic benefits of the loan. To date, repurchase activity pursuant to the terms of these representations and warranties has been insignificant to Pinnacle Bank.

The total amount of interest and penalties recorded in the income statement for the three months ended March 31, 2015 was $9,600. No interest and penalties were recorded for the three months ended March 31, 2016. PINNACLE FINANCIAL PARTNERS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) Pinnacle Financial's effective tax rate for the three months ended March 31, 2016 was 33.1% compared to 33.0% for the three months ended March 31, 2015. The difference between the effective tax rate and the Federal and State income tax statutory rate of 39.23% is primarily attributable to our investments in bank qualified municipal securities, investments in low-rate housing loans that qualify for Tennessee state excise tax credits and bank-owned life insurance, offset in part by meals and entertainment, a portion of which is non-deductible.

Commitments and Contingent Liabilities [Abstract]
Commitments and Contingent Liabilities	Note 7. Commitments and Contingent Liabilities In the normal course of business, Pinnacle Financial has entered into off-balance sheet financial instruments which include commitments to extend credit (i.e., including unfunded lines of credit) and standby letters of credit. Commitments to extend credit are usually the result of lines of credit granted to existing borrowers under agreements that the total outstanding indebtedness will not exceed a specific amount during the term of the indebtedness. Typical borrowers are commercial concerns that use lines of credit to supplement their treasury management functions, and thus their total outstanding indebtedness may fluctuate during any time period based on the seasonality of their business and the resultant timing of their cash flows. Other typical lines of credit are related to home equity loans granted to consumers. Commitments to extend credit generally have fixed expiration dates or other termination clauses and may require payment of a fee. At March 31, 2016, these commitments amounted to $2.5 billion. Standby letters of credit are generally issued on behalf of an applicant (our customer) to a specifically named beneficiary and are the result of a particular business arrangement that exists between the applicant and the beneficiary. Standby letters of credit have fixed expiration dates and are usually for terms of two years or less unless terminated beforehand due to criteria specified in the standby letter of credit. A typical arrangement involves the applicant routinely being indebted to the beneficiary for such items as inventory purchases, insurance, utilities, lease guarantees or other third party commercial transactions. The standby letter of credit would permit the beneficiary to obtain payment from Pinnacle Financial under certain prescribed circumstances. Subsequently, Pinnacle Financial would then seek reimbursement from the applicant pursuant to the terms of the standby letter of credit. At March 31, 2016, these commitments amounted to $100.9 million. Pinnacle Financial follows the same credit policies and underwriting practices when making these commitments as it does for on-balance sheet instruments. Each customer's creditworthiness is evaluated on a case-by-case basis, and the amount of collateral obtained, if any, is based on management's credit evaluation of the customer. Collateral held varies but may include cash, real estate and improvements, marketable securities, accounts receivable, inventory, equipment and personal property. The contractual amounts of these commitments are not reflected in the consolidated financial statements and only amounts drawn upon would be reflected in the future. Since many of the commitments are expected to expire without being drawn upon, the contractual amounts do not necessarily represent future cash requirements. However, should the commitments be drawn upon and should our customers default on their resulting obligation to us, Pinnacle Financial's maximum exposure to credit loss, without consideration of collateral, is represented by the contractual amount of those commitments. At each of March 31, 2016 and December 31, 2015, Pinnacle Financial had accrued $1.4 million for the inherent risks associated with these off-balance sheet commitments. Various legal claims also arise from time to time in the normal course of business. In the opinion of management, the resolution of these claims outstanding at March 31, 2016 will not have a material adverse impact on Pinnacle Financial's consolidated financial condition, operating results or cash flows.

Stock Options, Stock Appreciation Rights and Restricted Shares [Abstract]
Stock Options, Stock Appreciation Rights and Restricted Shares	Note 8. Stock Options, Stock Appreciation Rights and Restricted Shares As described more fully in the Annual Report on Form 10-K, as of March 31, 2016, Pinnacle Financial has one equity incentive plan under which it is able to grant awards, the 2014 Equity Incentive Plan (the "2014 Plan") and has assumed the stock option plan (the CapitalMark Option Plan) of CapitalMark in connection with the CapitalMark Merger. In addition, awards previously granted remain outstanding under equity plans previously adopted by Pinnacle Financial's Board of Directors or assumed in connection with acquisitions of Mid-America Bancshares, Inc. and Cavalry Bancorp, Inc. No new awards may be granted under these other plans or the CapitalMark Option Plan. PINNACLE FINANCIAL PARTNERS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) Total shares available for issuance under the 2014 Plan were approximately 918,080 shares as of March 31, 2016, inclusive of shares returned to plan reserves during the three months ended March 31, 2016. The 2014 Plan also permits Pinnacle Financial to reissue awards currently outstanding that are subsequently forfeited, settled in cash or expired unexercised and returned to the 2014 Plan. Common Stock Options and Stock Appreciation Rights As of March 31, 2016, there were 1,096,171 stock options and 2,481 stock appreciation rights outstanding to purchase common shares. A summary of the stock option and stock appreciation rights activity within the equity incentive plans during the three months ended March 31, 2016 and information regarding expected vesting, contractual terms remaining, intrinsic values and other matters is as follows: Number Weighted- Average Exercise Price Weighted- Average Contractual Remaining Term (in years) Aggregate Intrinsic Value (000's) Outstanding at December 31, 2015 1,251,601 $ 21.23 2.54 $ 37,714 (1) Granted - Exercised (152,949 ) Stock appreciation rights exercised - Forfeited - Outstanding at March 31, 2016 1,098,652 $ 21.02 2.58 $ 30,433 (2) Options exercisable at March 31, 2016 1,098,652 $ 21.02 2.58 $ 30,433 (2) (1) The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying awards and the quoted closing price of Pinnacle Financial common stock of $51.36 per common share at December 31, 2015 for the 1,251,601 options and stock appreciation rights that were in-the-money at December 31, 2015. (2) The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying awards and the quoted closing price of Pinnacle Financial common stock of $49.06 per common share at March 31, 2016 for the 1,098,652 options and stock appreciation rights that were in-the-money at March 31, 2016. Compensation costs related to unvested stock options granted under Pinnacle Financial's equity incentive plan had been fully recognized and all outstanding option awards are fully vested. Restricted Share Awards Additionally, the 2014 Plan provides for the granting of restricted share awards and other performance or market-based awards. There were no market-based awards outstanding as of March 31, 2016 under this plan. A summary of activity for unvested restricted share awards for the three months ended March 31, 2016 is as follows: Number Grant Date Weighted-Average Cost Unvested at December 31, 2015 866,314 $ 31.39 Shares awarded 91,033 Conversion of restricted share units to restricted share awards 43,694 Restrictions lapsed and shares released to associates/directors (189,843 ) Shares forfeited (1) (7,265 ) Unvested at March 31, 2016 803,933 $ 33.15 (1) Represents shares forfeited due to employee termination and/or retirement. No shares were forfeited due to failure to meet performance targets. PINNACLE FINANCIAL PARTNERS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) Compensation expense associated with the time-based restricted share awards is recognized over the time period that the restrictions associated with the awards lapse on a straight-line basis based on the total grant date fair value. Compensation expense associated with performance-based restricted share awards is recognized over the time period that the restrictions associated with the awards are anticipated to lapse based on a schedule consistent with the nature of the award. For the three months ended March 31, 2016, Pinnacle Financial recognized approximately $1.9 million in compensation costs attributable to restricted share awards, compared to $1.4 million for the three months ended March 31, 2015. Restricted Share Units Pinnacle Financial grants restricted share units to the senior executive officers and other members of the Leadership Team annually. The senior executive officers' restricted share unit award typically includes a range of shares that may be earned from the target level of performance to the maximum level of performance. The Leadership Team awards are granted at the target level of performance. Restricted share units awarded prior to 2015 will convert to a number of restricted share awards based on the achievement of certain performance metrics for each of the fiscal years to which the award relates, with the restrictions on the restricted shares issued in settlement of the restricted share units lapsing if Pinnacle Bank achieves certain soundness levels in subsequent years. Beginning in 2015, the awards will be settled in shares of freely tradeable common stock of Pinnacle Financial if the one year performance metrics and subsequent one-year service period requirements are met and subsequent soundness targets are achieved. The performance metrics for each of the performance periods is established concurrently with the award of the restricted share unit grants by the Human Resources Compensation Committee. The awards may be issued with a post-vest holding period, as shown below. During the post-vest holding period, the shares will not be released to the recipient and cannot be transferred, subject to limited exceptions, but will continue to accrue dividends until the awards are released, which is expected to be commensurate with the filing of Pinnacle Financial's Annual Report on Form 10-K for the prescribed year. These restricted share units are being expensed based on the requisite service period of the underlying tranche of the award. Each period, the number of shares that is expected to lapse to the recipient is reevaluated and the associated compensation expense is adjusted accordingly. The expense is accrued using an anticipated performance level for the senior executive officers between the target and maximum performance levels and at the target performance level for the Leadership Team.

Regulatory Matters [Abstract]
Regulatory Matters	Note 9. Regulatory Matters Pursuant to Tennessee banking law, Pinnacle Bank may not, without the prior consent of the Commissioner of the Tennessee Department of Financial Institutions (TDFI), pay any dividends to Pinnacle Financial in a calendar year in excess of the total of Pinnacle Bank's retained net income for that year plus the retained net income for the preceding two years. During the three months ended March 31, 2016, Pinnacle Bank paid $6.4 million in dividends to Pinnacle Financial. As of March 31, 2016, Pinnacle Bank could pay approximately $146.9 million of additional dividends to Pinnacle Financial without prior approval of the Commissioner of the TDFI. Pinnacle Financial increased its quarterly dividend to $0.14 beginning in the first quarter of 2016. The amount and timing of all future dividend payments, if any, is subject to Board discretion and will depend on Pinnacle Financial's earnings, capital position, financial condition and other factors, including new regulatory capital requirements, as they become known to us. Pinnacle Financial and Pinnacle Bank are subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary actions, by regulators that, if undertaken, could have a direct material effect on the financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, Pinnacle Financial and Pinnacle Bank must meet specific guidelines that involve quantitative measures of the assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The minimum capital level requirements applicable to bank holding companies and banks are: (i) a new common equity Tier 1 capital ratio of 4.5%; (ii) a Tier 1 risk-based capital ratio of 6% (increased from 4%); (iii) a total risk-based capital ratio of 8% (unchanged from current rules); (iv) a Tier 1 leverage ratio of 4% for all institutions. The capital level requirements also establish a "capital conservation buffer" of 2.5% (to be phased in over three years) above the new regulatory minimum risk-based capital ratios, and result in the following required ratios once the capital conservation buffer is fully phased in: PINNACLE FINANCIAL PARTNERS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) (i) a common equity Tier 1 risk-based capital ratio of 7%, (ii) a Tier 1 risk-based capital ratio of 8.5%, and (iii) a total risk-based capital ratio of 10.5%. As of January 1, 2016, compliance with the capital conservation buffer is determined by increasing the capital ratio minimum by 0.625% for the capital ratio with the least spread between regulatory minimum and calculated ratios. The buffer will increase each year until fully implemented in January 2019. An institution will be subject to limitations on paying dividends, engaging in share repurchases and paying discretionary bonuses if capital levels fall below minimum levels plus the buffer amounts. These limitations establish a maximum percentage of eligible retained income that could be utilized for such actions. To be considered well capitalized under applicable banking regulations following January 1, 2015, Pinnacle Financial and Pinnacle Bank must maintain the following minimum capital ratios and not be subject to a written agreement, order or directive to maintain a higher capital level: (i) a common equity Tier 1 capital ratio of 6.5% (ii) a Tier 1 risk based capital ratio of 8% (iii) a Total risk based capital ratio of 10%, and (iv) in the case of Pinnacle Bank, a Tier 1 leverage ratio of 5% Under current capital level requirements, Tier 1 capital generally consists of common stock (plus related surplus) and retained earnings, limited amounts of minority interest in the form of additional Tier 1 capital instruments, and non-cumulative preferred stock and related surplus, subject to certain eligibility standards, less goodwill and other specified intangible assets and other regulatory deductions. Cumulative preferred stock and trust preferred securities issued after May 19, 2010, will no longer qualify as Tier 1 capital, but such securities issued prior to May 19, 2010, including in the case of bank holding companies with less than $15.0 billion in total assets, trust preferred securities issued prior to that date, will continue to count as Tier 1 capital subject to certain limitations. As a result, Pinnacle Financial's Trust Preferred Securities continue to qualify as Tier 1 capital. The definition of Tier 2 capital is generally unchanged for most banking organizations, subject to certain new eligibility criteria. Common equity Tier 1 capital generally consists of common stock (plus related surplus) and retained earnings plus limited amounts of minority interest in the form of common stock, less goodwill and other specified intangible assets and other regulatory deductions. The current capital level requirements allow banks and their holding companies with less than $250 billion in assets a one-time opportunity to opt-out of a requirement to include unrealized gains and losses in accumulated other comprehensive income in their capital calculation. Pinnacle Financial has opted-out of this requirement. Management believes, as of March 31, 2016, that Pinnacle Financial and Pinnacle Bank met all capital adequacy requirements to which they are subject. To be categorized as well-capitalized under applicable banking regulations, Pinnacle Financial and Pinnacle Bank must maintain minimum total risk-based, Tier I risk-based, common equity Tier I and Tier I leverage ratios as set forth in the following table and not be subject to a written agreement, order or directive to maintain a higher capital level.

Derivative Instruments [Abstract]
Derivative Instruments	Note 10. Derivative Instruments Financial derivatives are reported at fair value in other assets or other liabilities. The accounting for changes in the fair value of a derivative depends on whether it has been designated and qualifies as part of a hedging relationship. For derivatives not designated as hedges, the gain or loss is recognized in current period earnings. Non-hedge derivatives Pinnacle Financial enters into interest rate swaps (swaps) to facilitate customer transactions and meet their financing needs. Upon entering into these instruments to meet customer needs, Pinnacle Financial enters into offsetting positions in order to minimize the risk to Pinnacle Financial. These swaps are derivatives, but are not designated as hedging instruments. Interest rate swap contracts involve the risk of dealing with counterparties and their ability to meet contractual terms. When the fair value of a derivative instrument contract is positive, this generally indicates that the counter party or customer owes Pinnacle Financial, and results in credit risk to Pinnacle Financial. When the fair value of a derivative instrument contract is negative, Pinnacle Financial owes the customer or counterparty and therefore, has no credit risk. A summary of Pinnacle Financial's interest rate swaps related to customers as of March 31, 2016 and December 31, 2015 is included in the following table (in thousands): March 31, 2016 December 31, 2015 Notional Amount Estimated Fair Value Notional Amount Estimated Fair Value Interest rate swap agreements: Pay fixed / receive variable swaps $ 470,055 $ 28,356 $ 396,112 $ 16,130 Pay variable / receive fixed swaps 470,055 (28,716 ) 396,112 (16,329 ) Total $ 940,110 $ (360 ) $ 792,224 $ (199 ) PINNACLE FINANCIAL PARTNERS, INC.

Pinnacle Financial has seven interest rate swap agreements designated as cash flow hedges intended to protect against the variability of cash flows on selected LIBOR based loans. The swaps hedge the interest rate risk, wherein Pinnacle Financial receives a fixed rate of interest from a counterparty and pays a variable rate, based on one month LIBOR. The terms of the respective swaps range from seven to ten years and started on July 1, 2014. The swaps were entered into with a counterparty that met Pinnacle Financial's credit standards and the agreements contain collateral provisions protecting the at-risk party. Pinnacle Financial believes that the credit risk inherent in the contract is not significant.

Fair Value of Financial Instruments [Abstract]
Fair Value of Financial Instruments	Note 11. Fair Value of Financial Instruments FASB ASC 820, Fair Value Measurements and Disclosures Valuation Hierarchy FASB ASC 820 establishes a three-level valuation hierarchy for disclosure of fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The three levels are defined as follows:  Level 1 – inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.  Level 2 – inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.  Level 3 – inputs to the valuation methodology are unobservable and significant to the fair value measurement. A financial instrument's categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Following is a description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of such assets and liabilities pursuant to the valuation hierarchy. Assets Securities available-for-sale identical PINNACLE FINANCIAL PARTNERS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) Other investments – Included in other investments are certain investments recorded at fair value primarily in certain nonpublic private equity funds. The valuation of nonpublic private equity investments requires management judgment due to the absence of observable quoted market prices, inherent lack of liquidity and the long-term nature of such assets. These investments are valued initially based upon transaction price. The carrying values of other investments are adjusted either upwards or downwards from the transaction price to reflect expected exit values as evidenced by financing and sale transactions with third parties, or when determination of a valuation adjustment is confirmed through ongoing reviews by senior investment managers. A variety of factors are reviewed and monitored to assess positive and negative changes in valuation including, but not limited to, current operating performance and future expectations of the particular investment, industry valuations of comparable public companies and changes in market outlook and the third-party financing environment over time. In determining valuation adjustments resulting from the investment review process, emphasis is placed on current company performance and market conditions. These investments are included in Level 3 of the valuation hierarchy as these funds are not widely traded and the underlying investments of such funds are often privately-held and/or start-up companies for which market values are not readily available.

PINNACLE FINANCIAL PARTNERS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) In the case of the investment securities portfolio, Pinnacle Financial monitors the portfolio to ascertain when transfers between levels have been affected. The nature of the remaining assets and liabilities is such that transfers in and out of any level are expected to be rare. For the three months ended March 31, 2016, there were no transfers between Levels 1, 2 or 3. The table below includes a rollforward of the balance sheet amounts for the three months ended March 31, 2016 (including the change in fair value) for financial instruments classified by Pinnacle Financial within Level 3 of the valuation hierarchy for assets and liabilities measured at fair value on a recurring basis. When a determination is made to classify a financial instrument within Level 3 of the valuation hierarchy, the determination is based upon the significance of the unobservable factors to the overall fair value measurement. However, since Level 3 financial instruments typically include, in addition to the unobservable or Level 3 components, observable components (that is, components that are actively quoted and can be validated to external sources), the gains and losses in the table below include changes in fair value due in part to observable factors that are part of the valuation methodology (in thousands): For the three months ended March 31, 2016 2015 Other assets Other liabilities Other assets Other liabilities Fair value, January 1 $ 9,764 $ - $ 8,004 $ - Total realized gains (losses) included in income 177 - 95 - Change in unrealized gains/losses included in other comprehensive income for assets and liabilities still held at period end - - - - Purchases 325 - 121 - Issuances - - - - Settlements (138 ) - (470 ) - Transfers out of Level 3 - - - - Fair value, March 31 10,128 - 7,750 - The amount of gains for the period included in earnings attributable to the change in unrealized gains relating to assets still held at the reporting date $ 177 $ - $ 95 $ - The following methods and assumptions were used by Pinnacle Financial in estimating its fair value disclosures for financial instruments that are not measured at fair value. In cases where quoted market prices are not available, fair values are based on estimates using discounted cash flow models. Those models are significantly affected by the assumptions used, including the discount rates, estimates of future cash flows and borrower creditworthiness. The fair value estimates presented herein are based on pertinent information available to management as of March 31, 2016 and December 31, 2015. Such amounts have not been revalued for purposes of these consolidated financial statements since those dates and, therefore, current estimates of fair value may differ significantly from the amounts presented herein. Securities held-to-maturity Loans, net PINNACLE FINANCIAL PARTNERS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) For variable-rate loans that reprice frequently and have no significant change in credit risk, fair values approximate carrying values. Fair values for impaired loans are estimated using discounted cash flow models or based on the fair value of the underlying collateral. For other loans, fair values are estimated using discounted cash flow models, using current market interest rates offered for loans with similar terms to borrowers of similar credit quality. The values derived from the discounted cash flow approach for each of the above portfolios are then further discounted to incorporate credit risk to determine the exit price. Mortgage loans held-for-sale - Deposits, securities sold under agreements to repurchase, Federal Home Loan Bank (FHLB) advances, subordinated debt and other borrowings Off-balance sheet instruments PINNACLE FINANCIAL PARTNERS, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) The following table presents the carrying amounts, estimated fair value and placement in the fair value hierarchy of Pinnacle Financial's financial instruments at March 31, 2016 and December 31, 2015. This table excludes financial instruments for which the carrying amount approximates fair value. For short-term financial assets such as cash and cash equivalents, the carrying amount is a reasonable estimate of fair value due to the relatively short time between the origination of the instrument and its expected realization. For financial liabilities such as non-interest bearing demand, interest-bearing demand, and savings deposits, the carrying amount is a reasonable estimate of fair value due to these products having no stated maturity (dollars in thousands).

The assumptions used to estimate the fair values are intended to approximate those that a market-participant would realize in a hypothetical orderly transaction. (2) At the end of each quarter, Pinnacle Financial evaluates the inherent risks of the outstanding off-balance sheet commitments. In making this evaluation, Pinnacle Financial evaluates the credit worthiness of the borrower, the collateral supporting the commitments and any other factors similar to those used to evaluate the inherent risks of our loan portfolio. Additionally, Pinnacle Financial evaluates the probability that the outstanding commitment will eventually become a funded loan. As a result, at March 31, 2016 and December 31, 2015, Pinnacle Financial included in other liabilities $0.9 million and $1.0 million, respectively, representing the inherent risks associated with these off-balance sheet commitments. (3) At March 31, 2016 and December 31, 2015, the fair value of Pinnacle Financial's standby letters of credit was $451,000 and $354,000, respectively. This amount represents the unamortized fee associated with these standby letters of credit and is included in the consolidated balance sheet of Pinnacle Financial and is believed to approximate fair value. This fair value will decrease over time as the existing standby letters of credit approach their expiration dates.

Rollforward of the Balance Sheet Amounts, Unobservable Input Reconciliation	The table below includes a rollforward of the balance sheet amounts for the three months ended March 31, 2016 (including the change in fair value) for financial instruments classified by Pinnacle Financial within Level 3 of the valuation hierarchy for assets and liabilities measured at fair value on a recurring basis. When a determination is made to classify a financial instrument within Level 3 of the valuation hierarchy, the determination is based upon the significance of the unobservable factors to the overall fair value measurement. However, since Level 3 financial instruments typically include, in addition to the unobservable or Level 3 components, observable components (that is, components that are actively quoted and can be validated to external sources), the gains and losses in the table below include changes in fair value due in part to observable factors that are part of the valuation methodology (in thousands): For the three months ended March 31, 2016 2015 Other assets Other liabilities Other assets Other liabilities Fair value, January 1 $ 9,764 $ - $ 8,004 $ - Total realized gains (losses) included in income 177 - 95 - Change in unrealized gains/losses included in other comprehensive income for assets and liabilities still held at period end - - - - Purchases 325 - 121 - Issuances - - - - Settlements (138 ) - (470 ) - Transfers out of Level 3 - - - - Fair value, March 31 10,128 - 7,750 - The amount of gains for the period included in earnings attributable to the change in unrealized gains relating to assets still held at the reporting date $ 177 $ - $ 95 $ -
Carrying Amounts, Estimated Fair Value and Placement in the Fair Value hierarchy of Financial Instruments	The following table presents the carrying amounts, estimated fair value and placement in the fair value hierarchy of Pinnacle Financial's financial instruments at March 31, 2016 and December 31, 2015. This table excludes financial instruments for which the carrying amount approximates fair value. For short-term financial assets such as cash and cash equivalents, the carrying amount is a reasonable estimate of fair value due to the relatively short time between the origination of the instrument and its expected realization. For financial liabilities such as non-interest bearing demand, interest-bearing demand, and savings deposits, the carrying amount is a reasonable estimate of fair value due to these products having no stated maturity (dollars in thousands). March 31, 2016 Carrying/ Notional Amount Estimated Fair Value (1) Quoted market prices in an active market (Level 1) Models with significant observable market parameters (Level 2) Models with significant unobservable market parameters (Level 3) Financial assets: Securities held-to-maturity $ 31,089 $ 31,521 $ - $ 31,521 $ - Loans, net 6,765,690 6,678,330 - - 6,678,330 Mortgage loans held-for-sale 35,437 36,188 - 36,188 - Loans held-for-sale 10,504 10,722 - 10,722 - Financial liabilities: Deposits and securities sold under agreements to repurchase 7,143,014 6,770,220 - - 6,770,220 Federal Home Loan Bank advances 616,290 616,636 - - 616,636 Subordinated debt and other borrowings 210,708 189,239 - - 189,239 Off-balance sheet instruments: Commitments to extend credit (2) 2,529,273 886 - - 886 Standby letters of credit (3) 100,940 451 - - 451 December 31, 2015 Financial assets: Securities held-to-maturity $ 31,377 $ 31,586 $ - $ 31,586 $ - Loans, net 6,477,803 6,379,153 - - 6,379,153 Mortgage loans held for sale 47,930 48,365 - 48,365 - Financial liabilities: Deposits and securities sold under agreements to repurchase 7,050,498 6,562,509 - - 6,562,509 Federal Home Loan Bank advances 300,305 299,214 - - 299,214 Subordinated debt and other borrowings 142,476 131,494 - - 131,494 Off-balance sheet instruments: Commitments to extend credit (2) 2,218,784 1,017 - - 1,017 Standby letters of credit (3) 93,534 354 - - 354 (1) Estimated fair values are consistent with an exit-price concept. The assumptions used to estimate the fair values are intended to approximate those that a market-participant would realize in a hypothetical orderly transaction. (2) At the end of each quarter, Pinnacle Financial evaluates the inherent risks of the outstanding off-balance sheet commitments. In making this evaluation, Pinnacle Financial evaluates the credit worthiness of the borrower, the collateral supporting the commitments and any other factors similar to those used to evaluate the inherent risks of our loan portfolio. Additionally, Pinnacle Financial evaluates the probability that the outstanding commitment will eventually become a funded loan. As a result, at March 31, 2016 and December 31, 2015, Pinnacle Financial included in other liabilities $0.9 million and $1.0 million, respectively, representing the inherent risks associated with these off-balance sheet commitments. (3) At March 31, 2016 and December 31, 2015, the fair value of Pinnacle Financial's standby letters of credit was $451,000 and $354,000, respectively. This amount represents the unamortized fee associated with these standby letters of credit and is included in the consolidated balance sheet of Pinnacle Financial and is believed to approximate fair value. This fair value will decrease over time as the existing standby letters of credit approach their expiration dates.

[1]	The amount represents the adjustment of the book value of CapitalMark's investment securities to their estimated fair value on the date of acquisition.
[2]	The amount represents the adjustment of the net book value of CapitalMark's loans to their estimated fair value based on current interest rates and expected cash flows, which includes estimates of expected credit losses inherent in the portfolio.
[3]	The amount represents the fair value of the core deposit intangible asset created in the acquisition.
[4]	The adjustment is necessary because the weighted average interest rate of CapitalMark's deposits exceeded the cost of similar funding at the time of acquisition. The fair value adjustment will be amortized to reduce future interest expense over the life of the portfolio.
[5]	The adjustment is necessary because the weighted average interest rate of CapitalMark's FHLB advances exceeded the cost of similar funding at the time of acquisition. The fair value adjustment will be amortized to reduce future interest expense over the life of the portfolio.

[1]	Potential problem loans represent those loans with a well-defined weakness and where information about possible credit problems of borrowers has caused management to have doubts about the borrower's ability to comply with present repayment terms. This definition is believed to be substantially consistent with the standards established by Pinnacle Bank's primary regulators for loans classified as substandard, excluding the impact of nonaccrual loans and troubled debt restructurings. Potential problem loans, which are not included in nonaccrual loans, amounted to approximately $112.5 million at March 31, 2016, compared to $105.0 million at December 31, 2015.
[2]	Included in nonaccrual loans at March 31, 2016 and December 31, 2015 are $10.8 million and $12.1 million, respectively, in loans acquired with deteriorated credit quality.
[3]	Troubled debt restructurings are presented as impaired loans; however, they continue to accrue interest at contractual rates

[1]	Potential problem loans represent those loans with a well-defined weakness and where information about possible credit problems of borrowers has caused management to have doubts about the borrower's ability to comply with present repayment terms. This definition is believed to be substantially consistent with the standards established by Pinnacle Bank's primary regulators for loans classified as substandard, excluding the impact of nonaccrual loans and troubled debt restructurings. Potential problem loans, which are not included in nonaccrual loans, amounted to approximately $112.5 million at March 31, 2016, compared to $105.0 million at December 31, 2015.
[2]	Included in nonaccrual loans at March 31, 2016 and December 31, 2015 are $10.8 million and $12.1 million, respectively, in loans acquired with deteriorated credit quality.
[3]	Troubled debt restructurings of $10.0 million and $8.1 million as of both March 31, 2016 and December 31, 2015, respectively, are classified as impaired loans pursuant to U.S. GAAP; however, these loans continue to accrue interest at contractual rates.

Share-based Compensation Arrangement by Share-based Payment Award [Line Items]
Shares available for issuances (in shares)							918,080
[1]	Represents shares forfeited due to employee termination and/or retirement. No shares were forfeited due to failure to meet performance targets.
[2]	The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying awards and the quoted closing price of Pinnacle Financial common stock of $51.36 per common share at December 31, 2015 for the 1,251,601 options and stock appreciation rights that were in-the-money at December 31, 2015.
[3]	The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying awards and the quoted closing price of Pinnacle Financial common stock of $49.06 per common share at March 31, 2016 for the approximately 1,098,652 options and stock appreciation rights that were in-the-money at March 31, 2016.
[4]	The forfeiture restrictions on these restricted share awards lapse in equal annual installments on the anniversary date of the grant.
[5]	These shares represent forfeitures resulting from recipients whose employment terminated during the year-to-date period ended March 31, 2016. Any dividends paid on shares for which the forfeiture restrictions do not lapse will be recouped by the Company at the time of termination.
[6]	Groups include employees (referred to as associates above), the leadership team which includes our named executive officers and other key senior leadership members, and outside directors. When restricted shares are awarded, a participant receives voting rights and forfeitable dividend rights with respect to the shares, but is not able to transfer the shares until the restrictions have lapsed. Once the restrictions lapse, the participant is taxed on the value of the award and may elect to sell some shares to pay the applicable income taxes associated with the award. For time-based restricted share awards, dividends paid on shares for which the forfeiture restrictions do not lapse will be recouped by the Company at the time of termination. For performance-based awards, dividends are placed into escrow until the forfeiture restrictions on such shares lapse.
[7]	Reflects conversion of restricted share units issued in prior years to restricted share awards.

[1]	At the end of each quarter, Pinnacle Financial evaluates the inherent risks of the outstanding off-balance sheet commitments. In making this evaluation, Pinnacle Financial evaluates the credit worthiness of the borrower, the collateral supporting the commitments and any other factors similar to those used to evaluate the inherent risks of our loan portfolio. Additionally, Pinnacle Financial evaluates the probability that the outstanding commitment will eventually become a funded loan. As a result, at March 31, 2016 and December 31, 2014, Pinnacle Financial included in other $0.9 million and $1.0 million, respectively, representing the inherent risks associated with these off-balance sheet commitments.
[2]	At March 31, 2016 and December 31, 2015, the fair value of Pinnacle Financial's standby letters of credit was $451,000 and $354,000, respectively. This amount represents the unamortized fee associated with these standby letters of credit and is included in the consolidated balance sheet of Pinnacle Financial and is believed to approximate fair value. This fair value will decrease over time as the existing standby letters of credit approach their expiration dates.
[3]	Estimated fair values are consistent with an exit-price concept. The assumptions used to estimate the fair values are intended to approximate those that a market-participant would realize in a hypothetical orderly transaction.
