Summary of Significant Accounting Policies	'
	Note 1.  Summary of Significant Accounting Policies
	Nature of Business — Pinnacle Financial Partners, Inc. (Pinnacle Financial) is a bank holding company whose primary business is conducted by its wholly-owned subsidiary, Pinnacle Bank. Pinnacle Bank is a commercial bank headquartered in Nashville, Tennessee. Pinnacle Bank provides a full range of banking services in its primary market areas of the Nashville-Davidson-Murfreesboro-Franklin, Tennessee and Knoxville, Tennessee Metropolitan Statistical Areas.
	Basis of Presentation — The accompanying unaudited consolidated financial statements have been prepared in accordance with instructions to Form 10-Q and therefore do not include all information and footnotes necessary for a fair presentation of financial position, results of operations, and cash flows in conformity with U.S. generally accepted accounting principles (U.S. GAAP).  All adjustments consisting of normally recurring accruals that, in the opinion of management, are necessary for a fair presentation of the financial position and results of operations for the periods covered by the report have been included.  The accompanying unaudited consolidated financial statements should be read in conjunction with the Pinnacle Financial consolidated financial statements and related notes appearing in the 2013 Annual Report previously filed on Form 10-K.
	These consolidated financial statements include the accounts of Pinnacle Financial and its wholly-owned subsidiaries. PNFP Statutory Trust I, PNFP Statutory Trust II, PNFP Statutory Trust III and PNFP Statutory Trust IV are affiliates of Pinnacle Financial and are included in these consolidated financial statements pursuant to the equity method of accounting. Significant intercompany transactions and accounts are eliminated in consolidation.
	Use of Estimates — The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the balance sheet date and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term include the determination of the allowance for loan losses, any potential impairment of intangible assets, including goodwill and the valuation of deferred tax assets, other real estate owned, and our investment portfolio, including other-than-temporary impairment. These financial statements should be read in conjunction with Pinnacle Financial's Annual Report on Form 10-K for the year ended December 31, 2013. There have been no significant changes to Pinnacle Financial's significant accounting policies as disclosed in Pinnacle Financial's Annual Report on Form 10-K for the year ended December 31, 2013.
	Cash Flow Information — Supplemental cash flow information addressing certain cash and noncash transactions for each of the three months ended March 31, 2014 and 2013 was as follows:
		For the three months ended March 31,
		2014		2013
	Cash Transactions:
	Interest paid	$	3,447,425	$	4,540,692
	Income taxes paid, net		6,100,000		7,100,000
	Noncash Transactions:
	Loans charged-off to the allowance for loan losses		1,503,511		3,557,313
	Loans foreclosed upon and transferred to other real estate owned		1,645,100		550,000
	Available-for-sale securities transferred to held-to-maturity portfolio		-		39,959,647
	Income Per Common Share — Basic net income per common share available to common stockholders (EPS) is computed by dividing net income available to common stockholders by the weighted average common shares outstanding for the period. Diluted EPS reflects the dilution that could occur if securities or other contracts to issue common stock were exercised or converted.  The difference between basic and diluted weighted average shares outstanding is attributable to common stock options, common stock appreciation rights, restricted share awards, and restricted share unit awards. The dilutive effect of outstanding options, common stock appreciation rights, restricted share awards, and restricted share unit awards is reflected in diluted EPS by application of the treasury stock method.
	The following is a summary of the basic and diluted net income per share calculations for the three months ended March 31, 2014 and 2013:
		For the three months ended
		March 31,
		2014		2013
	Basic net income per share calculation:
	Numerator - Net income available to common stockholders	$	16,367,123	$	13,448,125
	Denominator - Average common shares outstanding		34,602,337		33,987,265
	Basic net income per share available to common stockholders	$	0.47	$	0.4
	Diluted net income per share calculation:
	Numerator – Net income available to common stockholders	$	16,367,123	$	13,448,125
	Denominator - Average common shares outstanding		34,602,337		33,987,265
	Dilutive shares contingently issuable		364,263		218,937
	Average diluted common shares outstanding		34,966,600		34,206,202
	Diluted net income per share available to common stockholders	$	0.47	$	0.39

	At March 31, 2014, approximately $621,400.0 million of securities within Pinnacle Financial's investment portfolio were either pledged to secure public funds and other deposits or securities sold under agreements to repurchase.
	During 2013, approximately $40.0 million of available-for-sale securities were transferred to the held-to-maturity portfolio. The transfers of debt securities into the held-to-maturity category from the available-for-sale category were made at fair value at the date of transfer. The unrealized holding gain or loss at the date of transfer was retained in other comprehensive income and in the carrying value of the held-to-maturity securities. Such amounts will be amortized to interest income over the remaining life of the securities.
	The amortized cost and fair value of debt securities as of March 31, 2014 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. Therefore, these securities are not included in the maturity categories in the following summary (in thousands):

The applicable dates for determining when securities are in an unrealized loss position are March 31, 2014 and December 31, 2013. 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, 2014 and December 31, 2013, 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, 2014, Pinnacle Financial had approximately $17.1 million in unrealized losses on $380.4 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, 2014, 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, 2014.
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. There is also 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 3.  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).
	Commercial loans receive risk ratings by the assigned financial advisor 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, 2014, approximately 74% 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 the loan officer. At least annually, our credit procedures require that every risk rated loan of $250,000 or more be subject to a formal credit risk review process. 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.
	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.
	The following table outlines the amount of each loan classification categorized into each risk rating category as of March 31, 2014 and December 31, 2013 (in thousands):

	-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 substandard nonaccrual loans and substandard troubled debt restructurings. Potential problem loans, which are not included in nonaccrual loans, amounted to approximately $83.9 million at March 31, 2014, compared to $65.0 million at December 31, 2013.
	-2	Troubled debt restructurings are presented as an impaired loan; however, they continue to accrue interest at contractual rates.
	At March 31, 2014 and December 31, 2013, all loans classified as nonaccrual were deemed to be impaired. The principal balances of these nonaccrual loans amounted to $15.6 million and $18.2 million at March 31, 2014 and December 31, 2013, respectively, and are included in the tables above.  For the three months ended March 31, 2014, the average balance of nonaccrual loans was $16.1 million as compared to $21.5 million for the twelve months ended December 31, 2013.  At the date such loans were placed on nonaccrual status, Pinnacle Financial reversed all previously accrued interest income against current year earnings.  Had these nonaccrual loans been on accruing status, interest income would have been higher by $283,000 for the three months ended March 31, 2014 and by $292,000 for the three months ended March 31, 2013.
	The following table details the recorded investment, unpaid principal balance and related allowance and average recorded investment of our nonaccrual loans at March 31, 2014 and December 31, 2013 by loan classification and the amount of interest income recognized on a cash basis throughout the fiscal year-to-date period then ended, respectively, on these loans that remain on the balance sheets (in thousands):

(1)	Collateral dependent loans are typically charged-off to their net realizable value pursuant to requirements of our primary regulators and no specific allowance is carried related to those loans.
Pinnacle Financial's policy is that once a loan is placed on nonaccrual status each subsequent payment is reviewed on a case-by-case basis to determine if the payment should be applied to interest or principal pursuant to regulatory guidelines. Pinnacle Financial recognized no interest income from cash payments received on nonaccrual loans during the three months ended March 31, 2014 or during the year ended December 31, 2013.
Impaired loans also include loans that Pinnacle Bank has elected to formally restructure when, 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 March 31, 2014 and December 31, 2013, there were $15.1 million and $19.6 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 following table outlines the amount of each troubled debt restructuring categorized by loan classification made during the three months ended March 31, 2014 and 2013 (dollars in thousands):
		Three months ended March 31, 2014												Three months ended March 31, 2013

During the three months ended March 31, 2014, Pinnacle Financial did not have any troubled debt restructurings that subsequently defaulted within twelve months of the restructuring. During the three months ended March 31, 2013, two consumer real estate loans totaling $1.0 million which were previously classified as a troubled debt restructuring subsequently defaulted, within twelve months of the restructuring. A default of a troubled debt restructuring is defined as an occurrence which violates the terms of the receivable's contract.
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, 2014 with the comparative exposures for December 31, 2013 (in thousands):
	At March 31, 2014:

The adequacy of the allowance for loan losses is assessed at the end of each calendar quarter.  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.
At March 31, 2014, Pinnacle Financial had granted loans and other extensions of credit amounting to approximately $10.2 million to current directors, executive officers, and their related entities, of which $7.7 million had been drawn upon. At December 31, 2013, Pinnacle Financial had granted loans and other extensions of credit amounting to approximately $11.2 million to directors, executive officers, and their related entities, of which approximately $8.9 million had been drawn upon.  These loans and extensions of credit were made in the ordinary course of business on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable loans to persons not related to Pinnacle Bank and did not involve more that the normal risk of collectability or present other unfavorable features. None of these loans to directors, executive officers, and their related entities were impaired at March 31, 2014 or December 31, 2013.
Residential Lending
At March 31, 2014, Pinnacle Financial had approximately $14.0 million of mortgage loans held-for-sale compared to approximately $12.9 million at December 31, 2013.  During the first quarter of 2014, Pinnacle Financial began delivering loans on a mandatory basis to its approved investors. Mandatory delivery exposes Pinnacle to interest rate risk between the initial rate-lock and the ultimate sale of the loan to a third-party. Pinnacle Financial sells loans to third-party investors and has not entered into any forward commitments with investors for future bulk loan sales.  All of these loan sales transfer servicing rights to the buyer.  During the three months ended March 31, 2014, Pinnacle Financial recognized $952,200 in gains on the sale of these loans, net of commissions paid, compared to $1.8 million during the three months ended March 31, 2013.
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.

	Note 4.  Income Taxes
	Accounting Standards Codification (ASC) 740, Income Taxes, defines the threshold for recognizing the benefits of tax return positions in the financial statements as "more-likely-than-not" to be sustained by the taxing authority.  As of March 31, 2014, Pinnacle Financial had no unrecognized tax benefits related to Federal or State income tax matters and does not currently anticipate any material increase or decrease in unrecognized tax benefits relative to any tax positions taken prior to March 31, 2014. As of March 31, 2014, Pinnacle Financial has accrued no interest and no penalties related to uncertain tax positions.
	Pinnacle Financial's effective tax rate for the three months ended March 31, 2014 was 33.2% compared to 32.9% for the three months ended March 31, 2013.  The effective tax rate differs from the Federal income tax statutory rate of 35% and state income tax rate of 6.50% primarily due to our investments in bank qualified municipal securities, bank-owned life insurance, and tax savings from our captive insurance subsidiary, PNFP Insurance Inc., offset in part by meals and entertainment and executive compensation expense, portions of which are non-deductible.

Commitments and Contingent Liabilities	'
	Note 5.  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, 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, 2014, these commitments amounted to $1.3 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, 2014, these commitments amounted to $68.4 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 March 31, 2014, and December 31, 2013, Pinnacle Financial had accrued $1.4 million for the inherent risks associated with these off balance sheet commitments.
	During the fourth quarter of 2011, a customer of Pinnacle Bank filed a putative class action lawsuit (styled John Higgins, et al, v. Pinnacle Financial Partners, Inc., d/b/a Pinnacle National Bank) in Davidson County, Tennessee Circuit Court against Pinnacle Bank and Pinnacle Financial, on his own behalf, as well as on behalf of a purported class of Pinnacle Bank's customers within the State of Tennessee alleging that Pinnacle Bank's method of ordering debit card transactions had caused customers of Pinnacle Bank to incur higher overdraft charges than had a different method been used. In April 2014, an order was entered giving final approval to the settlement, and providing a release of claims against Pinnacle Bank and Pinnacle Financial. The order will become final absent the filing of an appeal on or before the thirtieth day following its issuance. Pinnacle Financial does not believe that any liability arising from this legal matter will have a material adverse effect on Pinnacle Financial's consolidated financial condition, operating results, or cash flows.
	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, 2014 will not have a material impact on Pinnacle Financial's consolidated financial condition, operating results or cash flows.

Stock Options, Stock Appreciation Rights and Restricted Shares	'
	Note 6.  Stock Options, Stock Appreciation Rights and Restricted Shares
	As described more fully in the Annual Report on Form 10-K, Pinnacle Financial had two equity incentive plans that had been approved by its shareholders at March 31, 2014.  Additionally, Pinnacle Financial had assumed equity plans in connection with acquisitions of Cavalry Bancorp, Inc. (Cavalry) and Mid-America Bancshares, Inc. (Mid-America) under which it had granted stock options and stock appreciation rights to its employees to purchase common stock at or above the fair market value on the date of grant and granted restricted share awards to employees and directors. At March 31, 2014, there were approximately 413,000 shares available for future issuances under the plans that have not expired.
	At Pinnacle Financial's annual shareholders' meeting on April 15, 2014, the shareholders of Pinnacle Financial voted in favor of a proposal that adopted the 2014 Equity Incentive Plan (the "2014 Plan").  The issuance of the 2014 Plan proposal addressed the following matters:
	(i)	Consolidation of the two existing equity incentive plans, the Pinnacle Financial Partners, Inc. 2004 Amended and Restated Equity Incentive Plan (the "2004 Plan") and the Mid-America Bancshares, Inc. 2006 Omnibus Equity Incentive Plan (the "Mid-America Plan") including approximately 396,000 shares in the aggregate that remain available for issuance under those two plans; and
	(ii)	Increased the maximum number of shares of common stock that may be issued to associates and directors by an additional 930,000 shares.
	As a result of the adoption of the 2014 Equity Incentive Plan, total shares available for issuance under the 2014 Plan increased to approximately 1,343,000 as of April 15, 2014. 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, 2014, there were 860,593 stock options and 4,716 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, 2014 and information regarding expected vesting, contractual terms remaining, intrinsic values and other matters is as follows:
			Number				Weighted-		Weighted-		Aggregate
							Average		Average		Intrinsic
							Exercise		Contractual		Value
							Price		Remaining Term		(000's)

	Options exercisable at March 31, 2014			865,309			$	26.6		2.41	$	8,858	(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 $32.53 per common share at December 31, 2013 for the approximately 931,425 options and stock appreciation rights that were in-the-money at December 31, 2013.
	-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 $37.49 per common share at March 31, 2014 for the approximately 865,309 options and stock appreciation rights that were in-the-money at March 31, 2014.
	During the three months ended March 31, 2014, Pinnacle Financial recorded no stock option compensation expense compared to $13,000 during the three months ended March 31, 2013. Compensation costs related to unvested stock options granted under Pinnacle Financial's equity incentive plans had been fully recognized at the end of the first quarter of 2013.  All outstanding option awards are fully vested.
	Restricted Share Awards
	Additionally, the 2004 plan, certain of the plans assumed in connection with the acquisition of Mid-America and the recently adopted 2014 plan provide 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, 2014 under any of these plans.
	A summary of activity for unvested restricted share awards for the three months ended March 31, 2014 is as follows:
			Number				Grant Date Weighted-Average Cost
	Unvested at December 31, 2013			821,695			$	19.18
	Shares awarded			90,979				32.28
	Conversion of restricted share units to restricted share awards			186,943				31.68
	Restrictions lapsed and shares released to associates/directors			(189,014	)			19.05
	Shares forfeited(1)			(16,985	)			21.11
	Unvested at March 31, 2014			893,618			$	23.12
	(1)	Represents shares forfeited due to employee termination and/or retirement. No shares were forfeited due to failure to meet performance targets.
	Pinnacle Financial grants restricted share awards to associates, executive management and outside directors with a combination of time and, in the case of executive management, performance vesting criteria. The following table outlines restricted stock grants that were made, grouped by similar vesting criteria, during the three months ended March 31, 2014:
	Grant	Group(1)	Vesting	Shares	Restrictions Lapsed and shares released to participants	Shares Forfeited by participants(5)	Shares Unvested
	Year		Period in years	awarded
	Time Based Awards(2)
	2014	Associates	5	78,780	-	274	78,506
	Performance Based Awards(3)
	2014	Leadership team	5	186,943	-	3,096	183,847
	Outside Director Awards(4)
	2014	Outside directors	1	12,199	-	-	12,199
	(1)	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 the 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 are subject to clawback at the time of termination. For performance-based awards, dividends are placed into escrow until the forfeiture restrictions on such shares lapse.
	-2	The forfeiture restrictions on these restricted share awards lapse  in equal annual installments on the anniversary date of the grant.
	-3	The forfeiture restrictions on these restricted share awards lapse in separate equal installments should Pinnacle Financial achieve certain earnings and soundness targets over each year of the subsequent vesting period.
	-4	Restricted share awards are issued to the outside members of the board of directors in accordance with their board compensation plan.  Restrictions lapse on the one year anniversary date of the award based on each individual board member meeting their attendance goals for the various board and board committee meetings to which each member was scheduled to attend.
	-5	These shares represent forfeitures resulting from terminations during the year-to-date period ended March 31, 2014. Any dividends paid on shares for which the forfeiture restrictions do not lapse are subject to clawback.
	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 cost of the award.  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, 2014, Pinnacle Financial recognized approximately $1.2 million in compensation costs attributable to all restricted share awards, compared to $951,000 for the three months ended March 31, 2013.
	Restricted Share Units
	Pinnacle Financial granted restricted share units to the senior executive officers and other members of the leadership team in the first quarter of 2014. The senior executive officers' restricted share unit award included a range from 58,404 units at the target compensation level to 102,209 units at the maximum compensation level.  These restricted share units will convert to a number of restricted share awards based on the achievement of certain performance metrics.  The Leadership Team restricted share unit award of 29,087 units was granted at a target level of performance.  For both senior executive officers and the Leadership Team, approximately one-third of these awards are eligible for conversion to restricted share awards based on the achievement of certain predetermined goals for each of the fiscal years ended December 31, 2014, 2015 and 2016, respectively.  Once converted to restricted share awards, the restrictions on these shares will lapse in 50% increments based on the attainment of certain soundness targets in fiscal 2017 and 2018.  The performance metrics and soundness criteria for each of the impacted fiscal years were established concurrently with the restricted share unit grants in January 2014 by the Human Resources and Compensation Committee of Pinnacle Financial's board of directors (HRCC).  These restricted share units are being expensed based on the requisite service period of the underlying traunche 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.  For the three months ended March 31, 2014, Pinnacle Financial recognized expense associated with the first traunche of this award totaling $52,000. The expense is being accrued at the mid-point of the range between target and maximum performance level for the senior executive officers and the target performance level for the Leadership Team.

Regulatory Matters [Abstract]	'
Regulatory Matters	'
	Note 7.  Regulatory Matters
	Pursuant to Tennessee banking law, Pinnacle Bank may not, without the prior consent of the Commissioner of the 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, 2014, Pinnacle Bank paid $4.9 million in dividends to Pinnacle Financial.  As of March 31, 2014, Pinnacle Bank could pay approximately $76.5 million of additional dividends to Pinnacle Financial without prior approval of the Commissioner of the TDFI. Pinnacle Financial initiated payment of a quarterly dividend of $0.08 per share of common stock in the fourth quarter of 2013 and has since declared two subsequent dividend payments.  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 capital guidelines that involve quantitative measures of the assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices.
	Quantitative measures established by regulation to ensure capital adequacy require Pinnacle Financial and Pinnacle Bank to maintain minimum amounts and ratios of Total and Tier I capital to risk-weighted assets and for Pinnacle Bank of Tier I capital to average assets. Management believes, as of March 31, 2014, 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, 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.  Pinnacle Financial's and Pinnacle Bank's actual capital amounts and ratios are presented in the following table (in thousands):
		Actual					Minimum Capital					Minimum
							Requirement					To Be Well-Capitalized
		Amount		Ratio			Amount		Ratio			Amount			Ratio
	At March 31, 2014
	Total capital to risk weighted assets:
	Pinnacle Financial	$	636,469		13.5	%	$	378,473		8	%	$	474,055			10	%
	Pinnacle Bank	$	610,921		12.9	%	$	377,709		8	%	$	473,112			10	%

	Pinnacle Bank	$	551,782		11.7	%	$	188,854		4	%	$	283,867			6	%

	(*) Average assets for the above calculations were based on the most recent quarter.
	In July 2013, the Federal Reserve Board and the FDIC approved final rules that substantially amend the regulatory risk-based capital rules applicable to Pinnacle Bank and Pinnacle Financial. The final rules implement the regulatory capital reforms of the Basel Committee on Banking Supervision reflected in "Basel III: A Global Regulatory Framework for More Resilient Banks and Banking Systems" (Basel III) and changes required by the Dodd-Frank Act.
	Under these rules, the leverage and risk-based capital ratios of bank holding companies may not be lower than the leverage and risk-based capital ratios for insured depository institutions. The final rules implementing the Basel III regulatory capital reforms will become effective as to Pinnacle Financial and Pinnacle Bank on January 1, 2015, and include new minimum risk-based capital and leverage ratios. Moreover, these rules refine the definition of what constitutes "capital" for purposes of calculating those ratios, including the definitions of Tier 1 capital and Tier 2 capital. The new minimum capital level requirements applicable to bank holding companies and banks subject to the rules 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 rules 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 minimum ratios once the capital conservation buffer is fully phased in: (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%. The capital conservation buffer requirement is to be phased in beginning in January 2016 at 0.625% of risk-weighted assets and would 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 plus the buffer amounts. These limitations establish a maximum percentage of eligible retained income that could be utilized for such actions.
	Under these new rules, Tier 1 capital will generally consist 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. The definition of Tier 2 capital is generally unchanged for most banking organizations, subject to certain new eligibility criteria.
	Common equity Tier 1 capital will generally consist 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 final rules 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 expects that it will opt-out of this requirement.

Derivative Instruments	'
	Note 8.  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 earnings.  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 with a large U.S. financial institution 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, 2014 and December 31, 2013 is included in the following table (in thousands):
			31-Mar-14							31-Dec-13
			Notional			Estimated				Notional				Estimated Fair Value
			Amount			Fair Value				Amount
	Interest rate swap agreements:
	Pay fixed / receive variable swaps		$	280,806		$	13,099			$	294,486			$	13,296

	Total		$	561,612		$	(377	)		$	588,972			$	(374	)
	Pinnacle Financial has a forward cash flow hedge relationship to manage future interest rate exposure. The hedging strategy converts the LIBOR based variable interest rate on forecasted borrowings to a fixed interest rate and protects Pinnacle Financial from floating interest rate variability.  The terms of the individual contracts within the relationship are as follows (in thousands):
												31-Mar-14						31-Dec-13

	-1	Pinnacle Financial will pay the fixed interest rate and the counterparties pay Pinnacle Financial the variable rate.
	-2	No cash will be exchanged prior to the term.
	The cash flow hedges were determined to be fully effective during the period presented. And therefore, no amount of ineffectiveness has been included in net income. The aggregate fair value of the swaps is recorded in other assets with changes in fair value recorded in accumulated other comprehensive (loss) income, net of tax. If a hedge was deemed to be ineffective, the amount included in accumulated other comprehensive (loss) income would be reclassified to current earnings. The hedge would no longer be considered effective if a portion of the hedge becomes ineffective, the item hedged is no longer in existence or Pinnacle Financial discontinues hedge accounting. Pinnacle Financial expects the hedges to remain fully effective during the remaining terms of the swaps. Pinnacle Financial does not expect any amounts to be reclassified from accumulated other comprehensive (loss) income related to these swaps over the next twelve months.

Fair Value of Financial Instruments [Abstract]	'
Fair Value of Financial Instruments	'
	Note 9.  Fair Value of Financial Instruments
	FASB ASC 820, Fair Value Measurements and Disclosures, which defines fair value, establishes a framework for measuring fair value in U.S. GAAP and expands disclosures about fair value measurements.  The definition of fair value focuses on the exit price, i.e., the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, not the entry price, i.e., the price that would be paid to acquire the asset or received to assume the liability at the measurement date.  The statement emphasizes that fair value is a market-based measurement; not an entity-specific measurement.  Therefore, the fair value measurement should be determined based on the assumptions that market participants would use in pricing the asset or liability.
	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 – Where quoted prices are available for identical securities in an active market, securities are classified within Level 1 of the valuation hierarchy. Level 1 securities include highly liquid government securities and certain other financial products. If quoted market prices are not available, then fair values are estimated by using pricing models that use observable inputs or quoted prices of securities with similar characteristics and are classified within Level 2 of the valuation hierarchy. In certain cases where there is limited activity or less transparency around inputs to the valuation and more complex pricing models or discounted cash flows are used, securities are classified within Level 3 of the valuation hierarchy.
	Other equity investments – Included in other investments are other equity investments 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 underling investments of such funds are often privately-held and/or start-up companies for which market values are not readily available.
	Other assets – Included in other assets are certain assets carried at fair value, including interest rate swap agreements, the cash flow hedge and interest rate locks associated with the mortgage loan pipeline.  The carrying amount of interest rate swap agreements is based on Pinnacle Financial's pricing models that utilize observable market inputs. The fair value of the cash flow hedge is determined by calculating the difference between the discounted fixed rate cash flows and the discounted variable rate cash flows.  The fair value of the mortgage loan pipeline is based upon the projected sales price of the underlying loans, taking into account market interest rates and other market factors at the measurement date, net of the projected fallout rate.  Pinnacle Financial reflects these assets within Level 2 of the valuation hierarchy as these assets are valued using similar transactions that occur in the market.
	Nonaccrual loans – A loan is classified as nonaccrual when it is probable Pinnacle Financial will be unable to collect all principal and interest payments due in accordance with the contractual terms of the loan agreement. Nonaccrual loans are measured based on the present value of expected payments using the loan's original effective rate as the discount rate, the loan's observable market price, or the fair value of the collateral less selling costs if the loan is collateral dependent. If the recorded investment in the nonaccrual loan exceeds the measure of fair value, a valuation allowance may be established as a component of the allowance for loan losses or the difference may be recognized as a charge-off. Nonaccrual loans are classified within Level 3 of the hierarchy due to the unobservable inputs used in determining their fair value such as collateral values and the borrower's underlying financial condition.
	Other real estate owned – Other real estate owned (OREO) represents real estate foreclosed upon by Pinnacle Bank through loan defaults by customers or acquired by deed in lieu of foreclosure.  Substantially all of these amounts relate to lots, homes and development projects that are either completed or are in various stages of construction for which Pinnacle Financial believes it has adequate collateral. Upon foreclosure, the property is recorded at the lower of cost or fair value, based on appraised value, less selling costs estimated as of the date acquired with any loss recognized as a charge-off through the allowance for loan losses.  Additional OREO losses for subsequent valuation downward adjustments are determined on a specific property basis and are included as a component of noninterest expense along with holding costs.  Any gains or losses realized at the time of disposal are also reflected in noninterest expense, as applicable.  OREO is included in Level 3 of the valuation hierarchy due to the lack of observable market inputs into the determination of fair value.  Appraisal values are property-specific and sensitive to the changes in the overall economic environment.
	Liabilities
	Other liabilities – Pinnacle Financial has certain liabilities carried at fair value including certain interest rate swap agreements to facilitate customer transactions.  The fair value of these liabilities is based on Pinnacle Financial's pricing models that utilize observable market inputs and is reflected within Level 2 of the valuation hierarchy.
	The following tables present financial instruments measured at fair value on a recurring basis as of March 31, 2014 and December 31, 2013, by caption on the consolidated balance sheets and by FASB ASC 820 valuation hierarchy (as described above) (in thousands):

	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, 2014, 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, 2014 (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):

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, 2014 and December 31, 2013. 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- Estimated fair values for investment securities are based on quoted market prices where available.  If quoted market prices are not available, then fair values are estimated by using pricing models that use observable inputs or quoted prices of securities with similar characteristics.
Loans, net - The fair value of our loan portfolio includes a credit risk factor in the determination of the fair value of our loans.  This credit risk assumption is intended to approximate the fair value that a market participant would realize in a hypothetical orderly transaction.  Our loan portfolio is initially fair valued using a segmented approach. We divide our loan portfolio into the following categories: variable rate loans, impaired loans and all other loans. The results are then adjusted to account for credit risk.
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 - Mortgage loans held-for-sale are carried at the lower of cost or fair value.  The estimate of fair value is based on pricing models and other information.
Deposits, securities sold under agreements to repurchase, Federal Home Loan Bank (FHLB) advances, subordinated debt and other borrowings - The carrying amounts of demand deposits, savings deposits, securities sold under agreements to repurchase, floating rate advances from the FHLB, floating rate subordinated debt and other borrowings, and floating rate loans approximate their fair values due to having no stated maturity. Fair values for certificates of deposit, fixed rate advances from the FHLB and fixed rate subordinated debt are estimated using discounted cash flow models, using current market interest rates offered on certificates, advances and other borrowings with similar remaining maturities.  For fixed rate subordinated debt, the maturity is assumed to be as of the earliest date that the indebtedness will be repriced.
Off-balance sheet instruments - The fair values of Pinnacle Financial's off-balance-sheet financial instruments are based on fees charged to enter into similar agreements. However, commitments to extend credit do not represent a significant value to Pinnacle Financial until such commitments are funded.
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, 2014 and December 31, 2013.  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 (in thousands).

-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, 2014 and December 31, 2013, Pinnacle Financial included in other liabilities $1.3 million representing the inherent risks associated with these off-balance sheet commitments.
-3	At March 31, 2014 and December 31, 2013, the fair value of Pinnacle Financial's standby letters of credit was $320,000 and $331,000, 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.

Note 10.  Variable Interest Entities

Under ASC 810, Pinnacle Financial is deemed to be the primary beneficiary and required to consolidate a variable interest entity (VIE) if it has a variable interest in the VIE that provides it with a controlling financial interest. For such purposes, the determination of whether a controlling financial interest exists is based on whether a single party has both the power to direct the activities of the VIE that most significantly impact the VIE's economic performance and the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. ASC 810 requires continual reconsideration of conclusions reached regarding which interest holder is a VIE's primary beneficiary and disclosures surrounding those VIE's which have not been consolidated. The consolidation methodology provided in this footnote for the quarter ended March 31, 2014, and the year ended December 31, 2013, has been prepared in accordance with ASC 810.

At March 31, 2014, Pinnacle Financial did not have any consolidated VIEs to disclose but did have several nonconsolidated VIEs.  As discussed more fully in its Annual Report on Form 10-K for the fiscal year ended December 31, 2013, Pinnacle Financial has the following non-consolidated variable interest entities: low income housing partnerships, trust preferred issuances and accruing restructured commercial loans.

The following table summarizes VIE's that are not consolidated by Pinnacle Financial as of March 31, 2014 and December 31, 2013 (in thousands):

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2014
Summary of Significant Accounting Policies [Abstract]	'
Basis of Presentation	'
	Basis of Presentation — The accompanying unaudited consolidated financial statements have been prepared in accordance with instructions to Form 10-Q and therefore do not include all information and footnotes necessary for a fair presentation of financial position, results of operations, and cash flows in conformity with U.S. generally accepted accounting principles (U.S. GAAP).  All adjustments consisting of normally recurring accruals that, in the opinion of management, are necessary for a fair presentation of the financial position and results of operations for the periods covered by the report have been included.  The accompanying unaudited consolidated financial statements should be read in conjunction with the Pinnacle Financial consolidated financial statements and related notes appearing in the 2013 Annual Report previously filed on Form 10-K.
	These consolidated financial statements include the accounts of Pinnacle Financial and its wholly-owned subsidiaries. PNFP Statutory Trust I, PNFP Statutory Trust II, PNFP Statutory Trust III and PNFP Statutory Trust IV are affiliates of Pinnacle Financial and are included in these consolidated financial statements pursuant to the equity method of accounting. Significant intercompany transactions and accounts are eliminated in consolidation.
Use of Estimates	'
	Use of Estimates — The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the balance sheet date and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term include the determination of the allowance for loan losses, any potential impairment of intangible assets, including goodwill and the valuation of deferred tax assets, other real estate owned, and our investment portfolio, including other-than-temporary impairment. These financial statements should be read in conjunction with Pinnacle Financial's Annual Report on Form 10-K for the year ended December 31, 2013. There have been no significant changes to Pinnacle Financial's significant accounting policies as disclosed in Pinnacle Financial's Annual Report on Form 10-K for the year ended December 31, 2013.
Cash Flow Information	'
	Cash Flow Information — Supplemental cash flow information addressing certain cash and noncash transactions for each of the three months ended March 31, 2014 and 2013 was as follows:
		For the three months ended March 31,
		2014		2013
	Cash Transactions:
	Interest paid	$	3,447,425	$	4,540,692
	Income taxes paid, net		6,100,000		7,100,000
	Noncash Transactions:
	Loans charged-off to the allowance for loan losses		1,503,511		3,557,313
	Loans foreclosed upon and transferred to other real estate owned		1,645,100		550,000
	Available-for-sale securities transferred to held-to-maturity portfolio		-		39,959,647
Income per Common Share Policy	'
	Income Per Common Share — Basic net income per common share available to common stockholders (EPS) is computed by dividing net income available to common stockholders by the weighted average common shares outstanding for the period. Diluted EPS reflects the dilution that could occur if securities or other contracts to issue common stock were exercised or converted.  The difference between basic and diluted weighted average shares outstanding is attributable to common stock options, common stock appreciation rights, restricted share awards, and restricted share unit awards. The dilutive effect of outstanding options, common stock appreciation rights, restricted share awards, and restricted share unit awards is reflected in diluted EPS by application of the treasury stock method.

	(1)	Represents shares forfeited due to employee termination and/or retirement. No shares were forfeited due to failure to meet performance targets.
	Pinnacle Financial grants restricted share awards to associates, executive management and outside directors with a combination of time and, in the case of executive management, performance vesting criteria. The following table outlines restricted stock grants that were made, grouped by similar vesting criteria, during the three months ended March 31, 2014:
	Grant	Group(1)	Vesting	Shares	Restrictions Lapsed and shares released to participants	Shares Forfeited by participants(5)	Shares Unvested
	Year		Period in years	awarded
	Time Based Awards(2)
	2014	Associates	5	78,780	-	274	78,506
	Performance Based Awards(3)
	2014	Leadership team	5	186,943	-	3,096	183,847
	Outside Director Awards(4)
	2014	Outside directors	1	12,199	-	-	12,199
	(1)	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 the 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 are subject to clawback at the time of termination. For performance-based awards, dividends are placed into escrow until the forfeiture restrictions on such shares lapse.
	-2	The forfeiture restrictions on these restricted share awards lapse  in equal annual installments on the anniversary date of the grant.
	-3	The forfeiture restrictions on these restricted share awards lapse in separate equal installments should Pinnacle Financial achieve certain earnings and soundness targets over each year of the subsequent vesting period.
	-4	Restricted share awards are issued to the outside members of the board of directors in accordance with their board compensation plan.  Restrictions lapse on the one year anniversary date of the award based on each individual board member meeting their attendance goals for the various board and board committee meetings to which each member was scheduled to attend.
	-5	These shares represent forfeitures resulting from terminations during the year-to-date period ended March 31, 2014. Any dividends paid on shares for which the forfeiture restrictions do not lapse are subject to clawback.

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, 2014 (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):

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, 2014 and December 31, 2013.  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 (in thousands).

	-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, 2014 and December 31, 2013, Pinnacle Financial included in other liabilities $1.3 million representing the inherent risks associated with these off-balance sheet commitments.
	-3	At March 31, 2014 and December 31, 2013, the fair value of Pinnacle Financial's standby letters of credit was $320,000 and $331,000, 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]	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 borrowerbs ability to comply with present repayment terms. This definition is believed to be substantially consistent with the standards established by Pinnacle Bankbs primary regulators for loans classified as substandard, excluding the impact of substandard nonaccrual loans and substandard troubled debt restructurings. Potential problem loans, which are not included in nonaccrual loans, amounted to approximately $83.9 million at March 31, 2014, compared to $65.0 million at December 31, 2013.
[2]	Troubled debt restructurings are presented as an impaired loan; however, they continue to accrue interest at contractual rates

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 $32.53 per common share at December 31, 2013 for the approximately 931,425 options and stock appreciation rights that were in-the-money at December 31, 2013.

[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 $37.49 per common share at March 31, 2014 for the approximately 865,309 options and stock appreciation rights that were in-the-money at March 31, 2014.

[3]

The forfeiture restrictions on these restricted share awards lapse in equal annual installments on the anniversary date of the grant.

[4]

The forfeiture restrictions on these restricted share awards lapse in separate equal installments should Pinnacle Financial achieve certain earnings and soundness targets over each year of the subsequent vesting period (or alternatively, the cumulative vesting period).

[5]

Restricted share awards are issued to the outside members of the board of directors in accordance with their board compensation plan. Restrictions lapse on the one year anniversary date of the award based on each individual board member meeting their attendance goals for the various board and board committee meetings to which each member was scheduled to attend.

[6]

Represents shares forfeited due to employee termination and/or retirement. No shares were forfeited due to failure to meet performance targets.

[7]

These shares represent forfeitures resulting from associate terminations during the year-to-date period ended March 31, 2014.

[8]

Groups include our employees (referred to as associates above), the leadership team - which includes our named executive officers and other key senior leadership members and, outside directors.B When the 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 are subject to clawback at the time of termination. For performance-based awards, dividends are placed into escrow until the forfeiture restrictions on such shares lapse.

Amount is net of a valuation allowance of $1.3 million at March 31, 2014 and $1.2 million at December 31, 2013 as required by ASC 310-10, bReceivables.b

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.

[3]

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, 2014 and December 31, 2013, Pinnacle Financial included in other liabilities $1.3 million and $1.2 million, respectively, representing the inherent risks associated with these off-balance sheet commitments.

[4]

At March 31, 2014 and December 31, 2013, the fair value of Pinnacle Financialbs standby letters of credit was $320,000 and $331,000, 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.
