PART I

Unless this Form 10-K indicates otherwise or the context otherwise requires, the terms "we," "our," "us," "the firm," "Pinnacle Financial Partners," "Pinnacle" or "Pinnacle Financial" as used herein refer to Pinnacle Financial Partners, Inc., and its subsidiaries, including Pinnacle Bank, which we sometimes refer to as "our bank subsidiary" or "our bank" and its other subsidiaries.  References herein to the fiscal years 2011, 2012, 2013, 2014, and 2015 mean our fiscal years ended December 31, 2011, 2012, 2013, 2014, and 2015, respectively.

ITEM 1.  BUSINESS

OVERVIEW

PRODUCTS AND SERVICES

Lending Services

We offer a full range of lending products, including commercial, real estate and consumer loans to individuals and small-to medium-sized businesses and professional entities.  We compete for these loans with competitors who are also well established in our geographic markets.

Pinnacle Bank's loan approval policies provide for various levels of officer lending authority. When the total amount of loans to a single borrower exceeds an individual officer's lending authority, officers with higher lending authority determine whether to approve any new loan requests or renewals of existing loans.  Loans to insiders require approval of the board, and, certain extensions of credit, including loans above certain amounts and certain adversely classified loans, require approval of a committee of the board.

Pinnacle Bank's lending activities are subject to a variety of lending limits imposed by federal and state law. Differing limits apply based on the type of loan or the nature of the borrower, including the borrower's relationship to Pinnacle Bank. In general, however, at December 31, 2015, we were able to loan any one borrower a maximum amount equal to approximately $105.6 million plus an additional $70.4 million, or a total of approximately $176.0 million, for loans that meet certain additional collateral guidelines. These legal limits will increase or decrease as Pinnacle Bank's capital increases or decreases as a result of its earnings or losses, the injection of additional capital, payments of dividends, acquisitions, or for other reasons. Pinnacle Bank's internal loan limit of $30 million is less than the legal lending limit, and Pinnacle Bank currently has three relationships in excess of the internal loan limit. These relationships range from $34.0 million to $40.0 million and were each approved by the Executive Committee of the Board of Directors.

The principal economic risk associated with each category of loans that Pinnacle Bank expects to make is the creditworthiness of the borrower. General economic factors affecting a commercial or consumer borrower's ability to repay include interest, inflation and unemployment rates, as well as other factors affecting a borrower's assets, clients, suppliers and employees.  Many of Pinnacle Bank's commercial loans are made to small- to medium-sized businesses that are sometimes less able to withstand competitive, economic and financial pressures than larger borrowers.  During periods of economic weakness these businesses may be more adversely affected than other enterprises and may cause increased levels of nonaccrual or other problem loans, loan charge-offs and higher provision for loan losses.

Pinnacle Bank's commercial clients borrow for a variety of purposes. The terms of these loans (which include equipment loans and working capital loans) will vary by purpose and by type of any underlying collateral. Commercial loans may be unsecured or secured by accounts receivable or by other business assets. Pinnacle Bank also makes a variety of commercial real estate loans, including both investment properties and business loans secured by real estate.

Pinnacle Bank also makes a variety of loans to individuals for personal, family, investment and household purposes, including secured and unsecured installment and term loans and lines of credit, residential first mortgage loans, home equity loans and home equity lines of credit.

Deposit Services

Pinnacle Bank seeks to establish a broad base of core deposits, including savings, checking, interest-bearing checking, money market and certificate of deposit accounts. To attract deposits, Pinnacle Bank has employed a marketing plan in its current geographic markets primarily based on relationship banking and features a broad product line and competitive rates and services. The primary sources of deposits are individuals and businesses located in those geographic markets. Pinnacle Bank traditionally has obtained these deposits primarily through personal solicitation by its officers and directors, although its use of media advertising has increased in recent years, primarily due to its advertising and banking sponsorship with the Tennessee Titans NFL football team.

Pinnacle Bank also offers its targeted commercial clients a comprehensive array of treasury management services as well as remote deposit services, which allow electronic deposits to be made from the client's place of business.

Investment, Trust and Insurance Services

Pinnacle Bank contracts with Raymond James Financial Services, Inc. (RJFS), a registered broker-dealer and investment adviser, to offer and sell various securities and other financial products to the public from Pinnacle Bank's locations through Pinnacle Bank employees that are also RJFS employees. RJFS is a subsidiary of Raymond James Financial, Inc.

Pinnacle Bank offers, through RJFS, non-FDIC insured investment products in order to assist Pinnacle Bank's clients in achieving their financial objectives consistent with their risk tolerances.  These financial products are offered by RJFS from Pinnacle Bank's main office and many of its other offices. Additionally, we believe that the brokerage and investment advisory program offered by RJFS complements Pinnacle Bank's general banking business, and further supports its business philosophy and strategy of delivering to our clients those products and services that meet their financial needs.  Pursuant to its contract with us, RJFS is primarily responsible for the compliance monitoring of dual employees of RJFS and Pinnacle Bank.  Additionally, Pinnacle Bank has developed its own compliance-monitoring program in an effort to further ensure that Pinnacle Bank personnel deliver these products in a manner consistent with the various regulations governing such activities. Pinnacle Bank receives a percentage of commission credits and fees generated by the program. Pinnacle Bank remains responsible for various expenses associated with the program, including promotional expenses, furnishings and equipment expenses and general personnel costs including commissions paid to licensed brokers.

Pinnacle Bank also maintains a trust department which provides fiduciary and investment management services for individual and commercial clients.  Account types include personal trust, endowments, foundations, individual retirement accounts, pensions and custody.  Pinnacle Advisory Services, Inc., a registered investment advisor, provides investment advisory services to its clients.  Additionally, Miller Loughry Beach Insurance Services, Inc., an insurance agency subsidiary of Pinnacle Bank, provides insurance products, particularly in the property and casualty area, to its clients.

Given client demand for being able to access banking and investment services easily, Pinnacle Bank also offers a broad array of convenience-centered products and services, including 24-hour telephone and online banking, mobile banking,  debit and credit cards, direct deposit, remote deposit and cash management services for small- to medium-sized businesses. Additionally, Pinnacle Bank is associated with a nationwide network of automated teller machines of other financial institutions that our clients are able to use throughout Tennessee and other regions. In many cases, Pinnacle Bank reimburses its clients for any fees that may be charged to the client for using the nationwide ATM network, providing greater convenience as compared to regional competitors.

Competitive Conditions

OTHER INFORMATION

Investment Securities

In addition to loans, Pinnacle Bank has investments primarily in United States agency securities, mortgage-backed securities, and state and municipal securities. No investment in any of those instruments exceeds any applicable limitation imposed by law or regulation. The executive committee of the board of directors reviews the investment portfolio on an ongoing basis in order to ensure that the investments conform to Pinnacle Bank's asset liability management policy as set by the board of directors.

---

Asset and Liability Management

Our Asset Liability Management Committee (ALCO), composed of senior managers of Pinnacle Bank, manages Pinnacle Bank's assets and liabilities and strives to provide a stable, optimized net interest income and margin, adequate liquidity and ultimately a suitable after-tax return on assets and return on equity. ALCO conducts these management functions within the framework of written policies that Pinnacle Bank's board of directors has adopted.  ALCO works to maintain an acceptable position between rate sensitive assets and rate sensitive liabilities.  The executive committee of the board of directors oversees the ALCO function on an ongoing basis.

SUPERVISION AND REGULATION

Both Pinnacle Financial and Pinnacle Bank are subject to extensive state and federal banking laws and regulations that impose restrictions on and provide for general regulatory oversight of Pinnacle Financial's and Pinnacle Bank's operations.  These laws and regulations are generally intended to protect depositors and borrowers, not stockholders.

Pinnacle Financial

Pinnacle Financial is a bank holding company under the federal Bank Holding Company Act of 1956. As a result, it is subject to the supervision, examination, and reporting requirements of the Bank Holding Company Act and the regulations of the Federal Reserve.

Acquisition of Banks. The Bank Holding Company Act requires every bank holding company to obtain the Federal Reserve's prior approval before:

•	Acquiring direct or indirect ownership or control of any voting shares of any bank if, after the acquisition, the bank holding company will directly or indirectly own or control more than 5% of the bank's voting shares;

•	Acquiring all or substantially all of the assets of any bank; or

•	Subject to certain exemptions, merging or consolidating with any other bank holding company.

Additionally, the Bank Holding Company Act provides that the Federal Reserve may not approve any of these transactions if it would substantially lessen competition or otherwise function as a restraint of trade, or result in or tend to create a monopoly, unless the anticompetitive effects of the proposed transaction are clearly outweighed by the public interest in meeting the convenience and needs of the communities to be served. The Federal Reserve is also required to consider the financial and managerial resources and future prospects of the bank holding companies and banks concerned; the effectiveness of the company in combating money laundering; the convenience and needs of the communities to be served; and the extent to which the proposal would result in greater or more concentrated risk to the United States banking or financial system.

Under the Bank Holding Company Act, as amended by the Dodd-Frank Act, if well-capitalized and well managed, a bank holding company located in Tennessee may purchase a bank located outside of Tennessee. Conversely, a well-capitalized and well managed bank holding company located outside of Tennessee may purchase a bank located inside Tennessee. In each case, however, state law restrictions may be placed on the acquisition of a bank that has only been in existence for a limited amount of time or will result in specified concentrations of deposits. For example, Tennessee law currently prohibits a bank holding company from acquiring control of a Tennessee-based financial institution until the target financial institution has been in operation for three years.

Change in Bank Control. Subject to various exceptions, the Bank Holding Company Act and the Federal Change in Bank Control Act, together with related regulations, require Federal Reserve approval prior to any person or company acquiring "control" of a bank holding company. Control is conclusively presumed to exist if an individual or company acquires 25% or more of any class of voting securities of the bank holding company. Control is refutably presumed to exist if a person or company acquires 10% or more, but less than 25%, of any class of voting securities and either:

•	The bank holding company has registered securities under Section 12 of the Securities Exchange Act of 1934; or

•	No other person owns a greater percentage of that class of voting securities immediately after the transaction.

Pinnacle Financial's common stock is registered under Section 12 of the Securities Exchange Act of 1934. The regulations provide a procedure for challenge of the rebuttable control presumption.

Permitted Activities. The Gramm-Leach-Bliley Act of 1999 amended the Bank Holding Company Act and expanded the activities in which bank holding companies and affiliates of banks are permitted to engage. The Gramm-Leach-Bliley Act eliminated many federal and state law barriers to affiliations among banks and securities firms, insurance companies, and other financial service providers, and provided that holding companies which elected to become financial holding companies could engage in activities that are:

•	Financial in nature;

•	Incidental to a financial activity (as determined by the Federal Reserve in consultation with the Secretary of the U.S. Treasury); or

The Gramm-Leach-Bliley Act expressly lists the following activities as financial in nature:

•	Lending, trust and other banking activities;

•	Insuring, guaranteeing, or indemnifying against loss or harm, or providing and issuing annuities, and acting as principal, agent, or broker for these purposes, in any state;

•	Providing financial, investment, or advisory services;

•	Issuing or selling instruments representing interests in pools of assets permissible for a bank to hold directly;

•	Underwriting, dealing in or making a market in securities;

•	Activities that the Federal Reserve has determined to be so closely related to banking or managing or controlling banks as to be a proper incident to banking or managing or controlling banks;

•	Activities permitted outside of the United States that the Federal Reserve has determined to be usual in connection with banking or other financial operations abroad;

•	Merchant banking through securities or insurance affiliates; and

•	Insurance company portfolio investments.

The Gramm-Leach-Bliley Act also authorizes the Federal Reserve, in consultation with the Secretary of the U.S. Treasury, to determine activities in addition to those listed above that are financial in nature or incidental to such financial activity. In determining whether a particular activity is financial in nature or incidental or complementary to a financial activity, the Federal Reserve must consider (1) the purpose of the Bank Holding Company Act and the Gramm-Leach-Bliley Act, (2) changes or reasonably expected changes in the marketplace in which financial holding companies compete and in the technology for delivering financial services, and (3) whether the activity is necessary or appropriate to allow financial holding companies to effectively compete with other financial service providers and to efficiently deliver information and services.  Pinnacle Financial became a financial holding company effective as of February 17, 2016.

Despite prior approval, the Federal Reserve may order a bank holding company or its subsidiaries to terminate any of these activities or to terminate its ownership or control of any subsidiary when it has reasonable cause to believe that the bank holding company's continued ownership, activity or control constitutes a serious risk to the financial safety, soundness, or stability of any of its bank subsidiaries.

Support of Subsidiary Institutions. Pinnacle Financial is required to act as a source of financial strength for its bank subsidiary, Pinnacle Bank, and to commit resources to support Pinnacle Bank. This support can be required at times when it would not be in the best interest of Pinnacle Financial's stockholders or creditors to provide it. In the event of Pinnacle Financial's bankruptcy, any commitment by it to a federal bank regulatory agency to maintain the capital of Pinnacle Bank would be assumed by the bankruptcy trustee and entitled to a priority of payment.

Pinnacle Bank

Pinnacle Financial owns one bank - Pinnacle Bank.  Pinnacle Bank is a state bank chartered under the laws of the State of Tennessee that is not a member of the Federal Reserve. As a result, it is subject to the supervision, examination and reporting requirements and the regulations of the Federal Deposit Insurance Corporation (FDIC) and Tennessee Department of Financial Institutions (TDFI). The TDFI has the authority to approve or disapprove mergers, the issuance of preferred stock and capital notes, the establishment of branches and similar corporate actions.  The TDFI regularly examines state banks like Pinnacle Bank and in connection with its examinations may identify matters necessary to improve a bank's operation in accordance with principles of safety and soundness.  Any matters identified in such examinations are required to be appropriately addressed by the bank. Pinnacle Bank is also subject to numerous state and federal statutes and regulations that will affect its business, activities and operations.

Branching. While the TDFI has authority to approve branch applications, state banks are required by the State of Tennessee to adhere to branching laws applicable to state chartered banks in the states in which they are located. With prior regulatory approval, Tennessee law permits banks based in the state to either establish new or acquire existing branch offices throughout Tennessee. As a result of the Dodd-Frank Act, Pinnacle Bank and any other national or state-chartered bank generally may branch across state lines to the same extent as banks chartered in the state of the branch.

FDIC Insurance. Deposits in Pinnacle Bank are insured by the FDIC up to $250,000 subject to applicable limitations. To offset the cost of this issuance, the FDIC has adopted a risk-based assessment system for insured depository institutions that takes into account the risks attributable to different categories and concentrations of assets and liabilities. Under the Dodd-Frank Act, the FDIC has adopted regulations that base deposit insurance assessments on total assets less capital rather than deposit liabilities and include off-balance sheet liabilities of institutions and their affiliates in risk-based assessments. After an institution's average assets exceed $10 billion over four quarters, the assessment rate increases compared to institutions at lower average asset levels.

At December 31, 2015, Pinnacle Bank's common equity Tier 1 capital ratio was 9.0%, its Tier 1 risk-based capital ratio was 9.0%, its total risk-based capital ratio was 10.6% and its leverage ratio was 8.8%, compared to 10.8%, 11.4%, 12.6% and 10.6% at December 31, 2014, respectively. At December 31, 2015, Pinnacle Financial's common equity Tier 1 capital ratio was 8.6%, its Tier 1 risk-based capital ratio was 9.6%, its total risk-based capital ratio was 11.2% and its leverage ratio was 9.4%, compared to 10.1%, 12.1%, 13.4% and 11.3% at December 31, 2014, respectively.  More information concerning Pinnacle Financial's and Pinnacle Bank's regulatory ratios at December 31, 2015 is included in Note 22 to the "Notes to Consolidated Financial Statements" included elsewhere in this Annual Report on Form 10-K.

Payment of Dividends

Pinnacle Financial is a legal entity separate and distinct from Pinnacle Bank. The principal source of Pinnacle Financial's cash flow, including cash flow to pay interest to its holders of subordinated debentures, and any dividends payable to common stockholders, are dividends that Pinnacle Bank pays to Pinnacle Financial as its sole stockholder. Under Tennessee law, Pinnacle Financial is not permitted to pay dividends if, after giving effect to such payment, it would not be able to pay its debts as they become due in the usual course of business or its total assets would be less than the sum of its total liabilities plus any amounts needed to satisfy any preferential rights if it were dissolving. In addition, in deciding whether or not to declare a dividend of any particular size, Pinnacle Financial's board of directors must consider its and Pinnacle Bank's current and prospective capital, liquidity, and other needs.

In addition to state law limitations on Pinnacle Financial's ability to pay dividends, the Federal Reserve imposes limitations on Pinnacle Financial's ability to pay dividends. As noted above, effective January 1, 2016, Federal Reserve regulations limit dividends, stock repurchases and discretionary bonuses to executive officers if Pinnacle Financial's regulatory capital is below the level of regulatory minimums plus the applicable capital conservation buffer which will increase each year until January 1, 2019.

Statutory and regulatory limitations also apply to Pinnacle Bank's payment of dividends to Pinnacle Financial.  Pinnacle Bank is required by Tennessee law to obtain the prior approval of the Commissioner of the TDFI for payments of dividends if the total of all dividends declared by its board of directors in any calendar year will exceed (1) the total of Pinnacle Bank's net income for that year, plus (2) Pinnacle Bank's retained net income for the preceding two years.  As of December 31, 2015, Pinnacle Bank could pay dividends to us of up to $180.0 million. Generally, federal regulatory policy encourages holding company debt to be serviced by subsidiary bank dividends or additional equity rather than debt issuances.  Pinnacle Financial currently has available cash balances which amounted to approximately $21.7 million at December 31, 2015.

The payment of dividends by Pinnacle Bank and Pinnacle Financial may also be affected by other factors, such as the requirement to maintain adequate capital above statutory and regulatory requirements imposed on Pinnacle Bank or Pinnacle Financial by their regulators. The federal banking agencies have indicated that paying dividends that deplete a depository institution's capital base to an inadequate level would be an unsafe and unsound banking practice. Under the Federal Deposit Insurance Corporation Improvement Act of 1991, a depository institution may not pay any dividend if payment would cause it to become undercapitalized or if it already is undercapitalized. Moreover, the federal agencies have issued policy statements that provide that bank holding companies and insured depository institutions should generally only pay dividends out of current operating earnings, and the new capital rules prohibit the payment of dividends when a holding company or insured depository institution is not in compliance with the capital conservation buffer described elsewhere in this report. See "Capital Adequacy" above.

During the fourth quarter of 2013, Pinnacle Financial Partners initiated a quarterly common stock dividend in the amount of $0.08 per share. During the year ended December 31, 2015, Pinnacle Financial Partners paid $18.3 million in dividends to common shareholders. On January 19, 2016, our Board of Directors declared a $0.14 quarterly cash dividend to common shareholders which should approximate $5.7 million in aggregate dividend payments that will paid on February 26, 2016 to common shareholders of record as of the close of business on February 5, 2016. The amount and timing of all future dividend payments, if any, is subject to Board discretion and will depend on our earnings, capital position, financial condition and other factors, including new regulatory capital requirements, as they become known to us.

Restrictions on Transactions with Affiliates

Both Pinnacle Financial and Pinnacle Bank are subject to the provisions of Section 23A of the Federal Reserve Act. Section 23A places limits on the amount of:

•	A bank's loans or extensions of credit, including purchases of assets subject to an agreement to repurchase, to or for the benefit of affiliates;

•	A bank's investment in affiliates;

•	Assets a bank may purchase from affiliates, except for real and personal property exempted by the Federal Reserve;

•	The amount of loans or extensions of credit to third parties collateralized by the securities or obligations of affiliates;

•	Transactions involving the borrowing or lending of securities and any derivative transaction that results in credit exposure to an affiliate; and

•	A bank's guarantee, acceptance or letter of credit issued on behalf of an affiliate.

The total amount of the above transactions is limited in amount, as to any one affiliate, to 10% of a bank's capital and surplus and, as to all affiliates combined, to 20% of a bank's capital and surplus. In addition to the limitation on the amount of these transactions, each of the above transactions must also meet specified collateral requirements. Pinnacle Bank must also comply with other provisions designed to avoid the taking of low-quality assets.

Pinnacle Financial and Pinnacle Bank are also subject to the provisions of Section 23B of the Federal Reserve Act which, among other things, prohibits an institution from engaging in the above transactions with affiliates unless the transactions are on terms substantially the same, or at least as favorable to the institution or its subsidiaries, as those prevailing at the time for comparable transactions with nonaffiliated companies.

Pinnacle Bank is also subject to restrictions on extensions of credit to its executive officers, directors, principal stockholders and their related interests. These extensions of credit (1) must be made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with third parties, and (2) must not involve more than the normal risk of repayment or present other unfavorable features.

Community Reinvestment

The Community Reinvestment Act (CRA) requires that, in connection with examinations of financial institutions within their respective jurisdictions, the Federal Reserve and the FDIC shall evaluate the record of each financial institution in meeting the credit needs of its local community, including low- and moderate-income neighborhoods. These facts are also considered in evaluating mergers, acquisitions, and applications to open a branch or facility. Failure to adequately meet these criteria could impose additional requirements and limitations on Pinnacle Bank. Additionally, banks are required to publicly disclose the terms of various Community Reinvestment Act-related agreements. Pinnacle Bank received a "satisfactory" CRA rating from its primary federal regulator on its most recent regulatory examination.

Privacy

Under the Gramm-Leach-Bliley Act, financial institutions are required to disclose their policies for collecting and protecting confidential information. Customers generally may prevent financial institutions from sharing personal financial information with nonaffiliated third parties except for third parties that market the institutions' own products and services. Additionally, financial institutions generally may not disclose consumer account numbers to any nonaffiliated third party for use in telemarketing, direct mail marketing or other marketing through electronic mail to consumers. Pinnacle Bank has established a privacy policy that it believes promotes compliance with these federal requirements.

Other Consumer Laws and Regulations

Interest and other charges collected or contracted for by Pinnacle Bank are subject to state usury laws and federal laws concerning interest rates. For example, under the Soldiers' and Sailors' Civil Relief Act of 1940, a lender is generally prohibited from charging an annual interest rate in excess of 6% on any obligations for which the borrower is a person on active duty with the United States military. Pinnacle Bank's loan operations are also subject to federal laws applicable to credit transactions, such as the:

Pinnacle Bank's deposit operations are subject to the:

•	Right to Financial Privacy Act, which imposes a duty to maintain confidentiality of consumer financial records and prescribes procedures for complying with administrative subpoenas of financial records; and

•

Electronic Funds Transfer Act and Regulation E issued by the Federal Reserve to implement that act, which govern automatic deposits to and withdrawals from deposit accounts and customers' rights and liabilities (including with respect to the permissibility of overdraft charges) arising from the use of automated teller machines and other electronic banking services.

Anti-Terrorism Legislation

On October 26, 2001, the President of the United States signed the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism (USA PATRIOT) Act of 2001. Under the USA PATRIOT Act, financial institutions are subject to prohibitions against specified financial transactions and account relationships as well as enhanced due diligence and "know your customer" standards in their dealings with foreign financial institutions and foreign customers.

In addition, the USA PATRIOT Act authorizes the Secretary of the U.S. Treasury to adopt rules increasing the cooperation and information sharing between financial institutions, regulators, and law enforcement authorities regarding individuals, entities and organizations engaged in, or reasonably suspected based on credible evidence of engaging in, terrorist acts or money laundering activities. Any financial institution complying with these rules will not be deemed to have violated the privacy provisions of the Gramm-Leach-Bliley Act, as discussed above. Pinnacle Bank currently has policies and procedures in place designed to comply with the USA PATRIOT Act.

Recent and Proposed Legislation and Regulatory Action

New regulations and statutes are regularly proposed that contain wide-ranging proposals for altering the structures, regulations and competitive relationships of the nation's financial institutions. In 2010, the U.S. Congress passed the Dodd-Frank Act, which includes significant consumer protection provisions related to, among other things, residential mortgage loans that have increased, and are likely to further increase, our regulatory compliance costs. We expect that the Dodd-Frank Act will continue to have a negative impact on our earnings through fee reductions, higher costs and new restrictions, particularly as we approach a level of total assets in excess of $10 billion. Upon consummation of our proposed merger with Avenue, which we expect will cause us to exceed $10 billion in total assets, we will also need to comply with certain additional requirements created by the Dodd-Frank Act that apply only to bank holding companies and banks with $10 billion or more in total assets. Failure to comply with the new requirements would negatively impact our results of operations and financial condition and could limit our growth or expansion activities. While we cannot predict what effect any presently contemplated or future changes in the laws or regulations or their interpretations would have on us, such changes could be materially adverse to our investors.

Our earnings are affected by domestic economic conditions and the monetary and fiscal policies of the United States government and its agencies. The Federal Reserve's monetary policies have had, and are likely to continue to have, an important impact on the operating results of commercial banks through the Federal Reserve's statutory power to implement national monetary policy in order, among other things, to curb inflation or combat a recession. The Federal Reserve, through its monetary and fiscal policies, affects the levels of bank loans, investments and deposits through its control over the issuance of United States government securities, its regulation of the discount rate applicable to member banks and its influence over reserve requirements to which member banks are subject. We cannot predict the nature or impact of future changes in monetary and fiscal policies.

ITEM 1A.  RISK FACTORS

Investing in our common stock involves various risks which are particular to our company, our industry and our market areas. If any of the following risks were to occur, we may not be able to conduct our business as currently planned and our financial condition or operating results could be materially and negatively impacted.  These matters could cause the trading price of our common stock to decline in future periods.

Fluctuations in interest rates could reduce our profitability.

The absolute level of interest rates as well as changes in interest rates may affect our level of interest income, the primary component of our gross revenue, as well as the level of our interest expense. Interest rate fluctuations are caused by many factors which, for the most part, are not under our control. For example, national monetary policy plays a significant role in the determination of interest rates. Additionally, competitor pricing and the resulting negotiations that occur with our customers also impact the rates we collect on loans and the rates we pay on deposits.

In December 2015, the Federal Reserve Board of Governors decided to raise the target range for the federal funds rate from 0% to 0.25% to 0.50%. As interest rates change, we expect that we will periodically experience "gaps" in the interest rate sensitivities of our assets and liabilities, meaning that either our interest-bearing liabilities (usually deposits and borrowings) will be more sensitive to changes in market interest rates than our interest-earning assets (usually loans and investment securities), or vice versa. In either event, if market interest rates should move contrary to our position, this "gap" may work against us, and our earnings may be negatively affected. During 2014 and 2015, and in anticipation of expected additional increases in short term interest rates in 2016, we reduced the amount of variable rate loans with interest rate floors by approximately $462 million. We believe that the reduction in the amount of variable rate loans with interest rate floors should better position our balance sheet for a rising rate environment. In the event that short-term interest rates don't continue to rise in 2016, or those rates rise more slowly than we are anticipating, our efforts to transition our balance sheet to a more asset sensitive position may negatively impact our results of operations as we may earn less interest on these loans than we would have had we maintained these loan floors.

Changes in the level of interest rates also may negatively affect our ability to originate loans, the value of our assets and our ability to realize gains from the sale of our assets, all of which ultimately affect our earnings. A decline in the market value of our assets may limit our ability to borrow additional funds. As a result, we could be required to sell some of our loans and investments under adverse market conditions, upon terms that are not favorable to us, in order to maintain our liquidity. If those sales are made at prices lower than the amortized costs of the investments, we will incur losses. Because we continue to have a significant number of loans with interest rate floors above current rates, in a rising rate environment our liabilities may reprice faster than our loans, which would negatively impact our results of operations.

We have entered into certain hedging transactions including interest rate swaps, which are designed to lessen elements of our interest rate exposure. In the event that interest rates do not change in the manner anticipated, such transactions may not be effective.

We have a concentration of credit exposure to borrowers in certain industries, and we also target small to medium-sized businesses.

We have meaningful credit exposures to borrowers in certain businesses, including commercial and residential building lessors, new home builders, and land subdividers. These industries experienced adversity during 2008 through 2010 as a result of sluggish economic conditions, and, as a result, an increased level of borrowers in these industries were unable to perform under their loan agreements with us, or suffered loan downgrades which negatively impacted our results of operations. If the economic environment in our markets weakens in 2016 or beyond, these industry concentrations could result in increased deterioration in credit quality, past dues, loan charge offs and collateral value declines, which could cause our earnings to be negatively impacted. Furthermore, any of our large credit exposures that deteriorate unexpectedly could cause us to have to make significant additional loan loss provisions, negatively impacting our earnings.

A substantial focus of our marketing and business strategy is to serve small to medium-sized businesses in our market areas. As a result, a relatively high percentage of our loan portfolio consists of commercial loans primarily to small to medium-sized businesses. At December 31, 2015, our commercial and industrial loans accounted for almost 34.1% of our total loans, up from 31.5% at December 31, 2010. Additionally, approximately, 16.6% of our loans at December 31, 2015 are owner-occupied commercial real estate loans, which are loans to businesses secured by the businesses' real estate. We expect to seek to expand the amount of such loans in our portfolio in 2016. During periods of lower economic growth like those we have experienced in recent years, small to medium-sized businesses may be impacted more severely and more quickly than larger businesses. Consequently, the ability of such businesses to repay their loans may deteriorate, and in some cases this deterioration may occur quickly, which would adversely impact our results of operations and financial condition.

Despite recent acquisitions we have made, we remain principally geographically concentrated in the Nashville, Tennessee and Knoxville, Tennessee MSAs, and changes in local economic conditions impact our profitability.

Prior to our acquisitions of CapitalMark and Magna, we operated primarily in the Nashville, Tennessee and Knoxville, Tennessee MSAs, and most of our borrowers, depositors and other customers lived or had operations in these areas. With our acquisitions of CapitalMark and Magna, we have increased our presence in the Knoxville MSA and expanded our operations into the Chattanooga, Tennessee – Georgia MSA and surrounding counties and the Memphis, Tennessee – Mississippi – Arkansas MSA, but the significant majority of our borrowers remain situated in the Nashville, Tennessee and Knoxville, Tennessee MSAs, and our proposed acquisition of Avenue will further increase the number of borrowers we have in the Nashville, Tennessee MSA. Our success significantly depends upon the growth in population, income levels, deposits and housing starts in our markets, along with the continued attraction of business ventures to these areas, and our profitability is impacted by the changes in general economic conditions in these markets. We cannot assure you that economic conditions, including loan demand, in our markets will improve during 2016 or thereafter, and in that case, we may not be able to grow our loan portfolio in line with our expectations, the ability of our customers to repay their loans to us may be negatively impacted and our financial condition and results of operations could be negatively impacted.

Even with our acquisitions of CapitalMark and Magna, compared to regional or national financial institutions, we are less able to spread the risks of unfavorable local economic conditions across a large number of diversified economies as we remain dependent on the economic environment within the State of Tennessee. Moreover, we cannot give any assurance that we will benefit from any market growth or return of more favorable economic conditions in our primary market areas if they do occur.

Our acquisitions and future expansion may result in additional risks.

In 2015, we completed the acquisitions of CapitalMark and Magna. On January 28, 2016 we announced the signing of a definitive merger agreement which provides for the merger of Avenue with and into Pinnacle Financial with Pinnacle Financial continuing as the surviving corporation. Avenue Bank and Pinnacle Bank will likewise merge if that transaction is consummated. We currently expect to consummate the Avenue merger in late second quarter or early third quarter in 2016.

We expect to continue to expand in Knoxville, Chattanooga and Memphis through additional branches and also may consider expansion within these markets and Nashville through additional acquisitions of all or part of other financial institutions. These types of expansions involve various risks, including:

Management of Growth .  We may be unable to successfully:

·	maintain loan quality in the context of significant loan growth;

·	avoid diversion or disruption of our existing operations or management as well as those of the acquired institution;

·	maintain adequate management personnel and systems to oversee such growth;

·	maintain adequate internal audit, loan review and compliance functions; and

·	implement additional policies, procedures and operating systems required to support such growth.

Operating Results .  There is no assurance that existing offices or future offices will maintain or achieve deposit levels, loan balances or other operating results necessary to avoid losses or produce profits. Our growth strategy necessarily entails growth in overhead expenses as we routinely add new offices and staff. Our historical results may not be indicative of future results or results that may be achieved as we continue to increase the number and concentration of our branch offices in our newer markets.

Development of Offices .  There are considerable costs involved in opening branches, and new branches generally do not generate sufficient revenues to offset their costs until they have been in operation for at least a year or more. Accordingly, any new branches we establish can be expected to negatively impact our earnings for some period of time until they reach certain economies of scale. The same is true for our efforts to expand in these markets with the hiring of additional seasoned professionals with significant experience in that market. Our expenses could be further increased if we encounter delays in opening any of our new branches. We may be unable to accomplish future branch expansion plans due to a lack of available satisfactory sites, difficulties in acquiring such sites, increased expenses or loss of potential sites due to complexities associated with zoning and permitting processes, higher than anticipated merger and acquisition costs or other factors. Finally, we have no assurance any branch will be successful even after it has been established or acquired, as the case may be.

Regulatory and Economic Factors .  Our growth and expansion plans may be adversely affected by a number of regulatory and economic developments or other events. Failure to obtain required regulatory approvals, changes in laws and regulations or other regulatory developments and changes in prevailing economic conditions or other unanticipated events may prevent or adversely affect our continued growth and expansion. Such factors may cause us to alter our growth and expansion plans or slow or halt the growth and expansion process, which may prevent us from entering our expected markets or allow competitors to gain or retain market share in our existing markets.

Failure to successfully address these and other issues related to our expansion could have a material adverse effect on our financial condition and results of operations, and could adversely affect our ability to successfully implement our business strategy. Also, if our growth occurs more slowly than anticipated or declines, our operating results could be materially adversely affected.

If our allowance for loan losses is not sufficient to cover losses inherent in our portfolio, our earnings will decrease.

If loan customers with significant loan balances fail to repay their loans, our earnings and capital levels will suffer. We make various assumptions and judgments about the probable losses in our loan portfolio, including the creditworthiness of our borrowers and the value of any collateral securing the loans. We maintain an allowance for loan losses to cover our estimate of the probable losses in our loan portfolio. In determining the size of this allowance, we utilize estimates  based on analyses of volume and types of loans, internal loan classifications, trends in classifications, volume and trends in delinquencies, nonaccruals and charge-offs, loss experience of various loan categories, national and local economic conditions, industry and peer bank loan quality indications, and other pertinent factors and information. If our assumptions are inaccurate, our current allowance may not be sufficient to cover potential loan losses, and additional provisions may be necessary which would decrease our earnings.

In addition, federal and state regulators periodically review our loan portfolio and may require us to increase our allowance for loan losses or recognize loan charge-offs. Their conclusions about the quality of a particular borrower or our entire loan portfolio may be different than ours. Any increase in our allowance for loan losses or loan charge offs as required by these regulatory agencies could have a negative effect on our operating results. Moreover, additions to the allowance may be necessary based on changes in economic and real estate market conditions, new information regarding existing loans, (including those we acquired in the Mergers) identification of additional problem loans, accounting rule changes and other factors, both within and outside of our management's control. These additions may require increased provision expense which would negatively impact our results of operations.

Negative developments in the U.S. and local economy may adversely impact our results in the future.

Economic conditions in the markets in which we operate deteriorated significantly between early 2008 and the middle of 2010. These challenges manifested themselves primarily in the form of increased levels of provisions for loan losses and other real estate expense related to declining collateral values in our real estate loan portfolio and increased costs associated with our portfolio of other real estate owned. Although economic conditions appear to have stabilized and strengthened in our markets in the more recent periods and we have refocused our efforts on growing our earning assets, we believe that we will continue to experience a slower growth economic environment in 2016. Accordingly, we expect that our results of operations could be negatively impacted by economic conditions, including reduced loan demand, in 2016. There can be no assurance that the economic conditions that have adversely affected the financial services industry, and the capital, credit and real estate markets, generally, or us in particular, will improve materially, or at all, in the near future, or thereafter, in which case we could experience reduced earnings or again experience significant losses and write-downs of assets, and could face capital and liquidity constraints or other business challenges.

We may not be able to successfully integrate CapitalMark, Magna or Avenue or to realize the anticipated benefits of the mergers.

We are still in the process of integrating CapitalMark and Magna, and, upon consummation of the proposed Avenue merger, will begin the process of integrating Avenue. A successful integration of these banks' operations with our operations will depend substantially on our ability to consolidate operations, corporate cultures, systems and procedures and to eliminate redundancies and costs. We may not be able to combine our operations with the operations of CapitalMark, Magna and Avenue without encountering difficulties, such as:

·	the loss of key employees;

·	the disruption of operations and business;

·	inability to maintain and increase competitive presence;

·	loan and deposit attrition, customer loss and revenue loss;

·	possible inconsistencies in standards, control procedures and policies;

·	unexpected problems with costs, operations, personnel, technology and credit; and/or

·	problems with the assimilation of new operations, sites or personnel, which could divert resources from regular banking operations.

Additionally, general market and economic conditions or governmental actions affecting the financial industry generally may inhibit our successful integration of CapitalMark, Magna and Avenue.

Further, we acquired CapitalMark and Magna, and have entered into the definitive agreement to acquire Avenue, with the expectation that these mergers will result in various benefits including, among other things, benefits relating to enhanced revenues, a strengthened market position for the combined company, cross selling opportunities, technology, cost savings and operating efficiencies. Achieving the anticipated benefits of these mergers is subject to a number of uncertainties, including whether we integrate CapitalMark, Magna and Avenue in an efficient and effective manner, and general competitive factors in the marketplace. Failure to achieve these anticipated benefits could result in a reduction in the price of our shares as well as in increased costs, decreases in the amount of expected revenues and diversion of management's time and energy and could materially and adversely affect our business, financial condition and operating results. Additionally, we made fair value estimates of certain assets and liabilities in recording the CapitalMark and Magna mergers, and, upon consummation of the proposed Avenue merger, will make such estimates in recording the Avenue merger. Actual values of these assets and liabilities could differ from our estimates, which could result in our not achieving the anticipated benefits of such mergers. Finally, any cost savings that are realized may be offset by losses in revenues or other charges to earnings.

The combined company will incur significant transaction and merger-related costs in connection with the mergers of CapitalMark and Avenue.

We expect to incur significant costs associated with combining the operations of CapitalMark (for whom we have scheduled systems conversions for March 2016) and Avenue with our operations. We continue to work diligently to finalize detailed integration plans to deliver anticipated cost savings, but additional unanticipated costs may be incurred in the integration of our business with the businesses of CapitalMark, Magna and Avenue. Although we expect that the elimination of duplicative costs, as well as the realization of other efficiencies related to the integration of the businesses, may offset incremental transaction and merger-related costs over time, this net benefit may not be achieved in the near term, or at all.

Whether or not the Avenue merger is consummated, we will incur substantial expenses, such as legal, accounting and financial advisory fees, in pursuing the Avenue merger which will adversely impact our earnings until after the acquisition has been completed. Completion of the Avenue merger is conditioned upon the receipt of all material governmental authorizations, consents, orders and approvals, including approval by federal banking regulators. We and Avenue intend to pursue all required approvals in accordance with the merger agreement.

Failure to complete the Avenue merger could cause our stock price to decline.

If the Avenue merger is not completed for any reason, our stock price may decline because costs related to the Avenue merger, such as legal, accounting and financial advisory fees, must be paid even if the Avenue merger is not completed. In addition, if the Avenue merger is not completed, our stock price may decline to the extent that the current market price reflects a market assumption that the Avenue merger will be completed.

We may face risks with respect to future acquisitions.

When we attempt to expand our business through mergers and acquisitions (as we have aggressively done in 2015 and 2016), we seek targets that are culturally similar to us, have experienced management and possess either significant market presence or have potential for improved profitability through economies of scale or expanded services. In addition to the general risks associated with our growth plans which are highlighted above, in general acquiring other banks, businesses or branches involves various risks commonly associated with acquisitions, including, among other things:

·	the time and costs associated with identifying and evaluating potential acquisition and merger targets;

·	inaccuracies in the estimates and judgments used to evaluate credit, operations, management and market risks with respect to the target institution;

·	the time and costs of evaluating new markets, hiring experienced local management and opening new bank locations, and the time lags between these activities and the generation of sufficient assets and deposits to support the costs of the expansion;

·	our ability to finance an acquisition and possible dilution to our existing shareholders;

·	the diversion of our management's attention to the negotiation of a transaction;

·	the incurrence of an impairment of goodwill associated with an acquisition and adverse effects on our results of operations;

·	entry into new markets where we lack experience; and

·	risks associated with integrating the operations and personnel of the acquired business.

We expect to continue to evaluate merger and acquisition opportunities that are presented to us in our current and expected markets and conduct due diligence activities related to possible transactions with other financial institutions. As a result, merger or acquisition discussions and, in some cases, negotiations may take place and future mergers or acquisitions involving cash, debt or equity securities may occur at any time. Generally, acquisitions of financial institutions involve the payment of a premium over book and market values, and, therefore, some dilution of our book value and fully diluted earnings per share may occur in connection with any future transaction. Failure to realize the expected revenue increases, cost savings, increases in product presence and/or other projected benefits from an acquisition could have a material adverse effect on our financial condition and results of operations.

Implementation of the various provisions of the Dodd-Frank Act may increase our operating costs or otherwise have a material effect on our business, financial condition or results of operations.

On July 21, 2010, President Obama signed the Dodd-Frank Act. This landmark legislation includes, among other things, (i) the creation of a Financial Services Oversight Counsel to identify emerging systemic risks and improve interagency cooperation; (ii) the elimination of the Office of Thrift Supervision and the transfer of oversight of federally chartered thrift institutions and their holding companies to the Office of the Comptroller of the Currency and the Federal Reserve; (iii) the creation of a Consumer Financial Protection Agency authorized to promulgate and enforce consumer protection regulations relating to financial products that would affect banks and non-bank finance companies; (iv) the establishment of new capital and prudential standards for banks and bank holding companies; (v) the termination of investments by the U.S. Treasury under TARP; (vi) enhanced regulation of financial markets, including the derivatives, securitization and mortgage origination markets; (vii) the elimination of certain proprietary trading and private equity investment activities by banks; (viii) the elimination of barriers to de novo interstate branching by banks; (ix) a permanent increase of FDIC deposit insurance to $250,000; (x) the authorization of interest-bearing transaction accounts; and (xi) changes in how the FDIC deposit insurance assessments will be calculated and an increase in the minimum designated reserve ratio for the Deposit Insurance Fund.

Certain provisions of the legislation were not immediately effective or are subject to required studies and implementing regulations. Further, community banks with less than $10 billion in assets (like us at December 31, 2015) are exempt from certain provisions of the legislation. However, we currently expect to exceed $10 billion in assets upon consummation of our proposed merger with Avenue, which will cause us to become subject to these additional regulations, and, as described below, our results of operations may be materially impacted by the additional costs to comply with these additional regulations as well as the higher costs associated with increased deposit insurance premiums.

The Dodd-Frank Act and its implementing regulations impose various additional requirements on bank holding companies with $10 billion or more in total assets, including compliance with portions of the Federal Reserve's enhanced prudential oversight requirements and annual stress testing requirements. In addition, banks with $10 billion or more in total assets are primarily examined by the CFPB with respect to various federal consumer financial protection laws and regulations. Currently, Pinnacle Bank is subject to regulations adopted by the CFPB, but the FDIC is primarily responsible for examining our compliance with consumer protection laws and those CFPB regulations. As a relatively new agency with evolving regulations and practices, there is uncertainty as to how the CFPB's examination and regulatory authority might impact our business.

Once our assets exceed $10 billion, we will be required, under the Dodd-Frank Act, to submit annually a stress test to the Federal Reserve that projects our performance in various economic scenarios provided by the Federal Reserve. The Dodd-Frank Act stress tests are forward-looking exercises conducted by the Federal Reserve and financial companies regulated by the Federal Reserve to help ensure institutions have sufficient capital to absorb losses and support operations during adverse economic conditions. Once we become required to perform these stress tests, we will be required to make certain assumptions in modeling future performance and must support these assumptions through statistical analysis and observed market behavior where applicable.  The outcome of the Federal Reserve's analysis of our projected performance (to include capital, earnings, and balance sheet changes) will be used in supervision of us and will assist the Federal Reserve in assessing our risk profile and capital adequacy. The results of any stress test that we are required to perform could hinder our ability to pay quarterly cash dividends to shareholders as has been our practice, and could also impact decisions made by the Federal Reserve and other bank regulators regarding future acquisitions or investments by us or Pinnacle Bank.

In addition, once our assets exceed $10 billion, we will be subject to the Durbin Amendment promulgated under the Dodd-Frank Act. Under the Durbin Amendment, interchange fees for debit card transactions are capped at $0.21 plus five basis points. This limitation on interchange fees will adversely impact our results of operations.

Compliance with these requirements that will become applicable to us once we exceed $10 billion in total assets may necessitate that we hire additional compliance or other personnel, design and implement additional internal controls, or incur other significant expenses, any of which could have a material adverse effect on our business, financial condition or results of operations. Compliance with the annual stress testing requirements, part of which must be publicly disclosed, may also be misinterpreted by the market generally or our customers and, as a result, may adversely affect our stock price or our ability to retain our customers or effectively compete for new business opportunities. To ensure compliance with these heightened requirements when effective, our regulators may require us to fully comply with these requirements or take actions to prepare for compliance even before our total assets equal or exceed $10 billion. As a result, we may incur compliance-related costs before we might otherwise be required, including if we are unable to consummate our merger with Avenue or do not continue to grow at the rate we expect or at all. Our regulators may also consider our preparation for compliance with these regulatory requirements when examining our operations generally or considering any request for regulatory approval we may make, even requests for approvals on unrelated matters.

Although several regulations implementing portions of the Dodd-Frank Act have been promulgated, we are still unable to predict how this significant legislation may be interpreted and enforced or how implementing regulations and supervisory policies may affect us. There can be no assurance that these or future reforms will not significantly increase our compliance or operating costs or otherwise have a significant impact on our business, financial condition and results of operations.

Our ability to declare and pay dividends is limited.

While our board of directors has approved the payment of a quarterly cash dividend on our common stock since the fourth quarter of 2013, there can be no assurance of whether or when we may pay dividends on our common stock in the future. Future dividends, if any, will be declared and paid at the discretion of our board of directors and will depend on a number of factors. Our principal source of funds used to pay cash dividends on our common stock will be dividends that we receive from Pinnacle Bank. Although Pinnacle Bank's asset quality, earnings performance, liquidity and capital requirements will be taken into account before we declare or pay any future dividends on our common stock, our board of directors will also consider our liquidity and capital requirements and our board of directors could determine to declare and pay dividends without relying on dividend payments from Pinnacle Bank.

Federal and state banking laws and regulations and state corporate laws restrict the amount of dividends we may declare and pay. For example, Federal Reserve Board regulations implementing the capital rules required under Basel III do not permit dividends unless capital levels exceed certain higher levels applying capital conservation buffers that began to apply on January 1, 2016 and are being phased in over three years.

In addition, the terms of the indentures pursuant to which our subordinated debentures have been issued, and the terms of the subordinated notes Pinnacle Financial will assume upon the consummation of the Avenue merger, prohibit us from paying dividends on our common stock at times when we are deferring the payment of interest on our subordinated debentures or the subordinated notes Pinnacle Financial will assume upon consummation of the Avenue merger.

Our ability to grow our loan portfolio may be limited by, among other things, economic conditions, competition within our market areas, the timing of loan repayments and seasonality.

Our ability to continue to improve our operating results is dependent upon, among other things, aggressively growing our loan portfolio. While we believe that our strategy to grow our loan portfolio is sound and our growth targets are achievable over an extended period of time, competition within our market areas is significant, particularly for borrowers whose businesses have been less negatively impacted by the challenging economic conditions of the last few years.  We compete with both large regional and national financial institutions, who are sometimes able to offer more attractive interest rates and other financial terms than we choose to offer, and smaller community-based financial institutions who seek to offer a similar level of service to that which we offer.  This competition can make loan growth challenging, particularly if we are unwilling to price loans at levels that would cause unacceptable levels of compression of our net interest margin or if we are unwilling to structure a loan in a manner that we believe results in a level of risk to us that we are not willing to accept.  Moreover, loan growth throughout the year can fluctuate due in part to seasonality of the businesses of our borrowers and potential borrowers and the timing on loan repayments, particularly those of our borrowers with significant relationships with us, resulting from, among other things, excess levels of liquidity.

Our investment in BHG may not produce the contribution to our results of operations that we expect.

On February 4, 2015 we acquired a 30% interest in BHG for $75 million in cash. On January 19, 2016, we entered into a definitive purchase agreement to acquire an additional 19% interest in BHG for $114.0 million payable in a mix of cash and shares of our common stock. We currently expect, subject to the satisfaction of customary closing conditions, to close the additional investment in early March. Although we have made other investments in businesses that we do not control, this is the largest investment of this type that we have made. While we have a significant stake in BHG, are entitled to designate one member of BHG's four person board of managers (and upon the closing of the additional investment, we will be entitled to designate two of the five members of BHG's board of managers) and in some instances have protective rights to block BHG from engaging in certain activities, we do not control BHG and the other managers and members of BHG may make most decisions regarding BHG's operations without our consent or approval, including a decision to sell BHG subject to the satisfaction of certain conditions (although, upon the closing of the additional investment, the board of managers of BHG will not be permitted to validly approve a sale of BHG without the consent of one of the two managers appointed by us for four years). Any sale of all or a portion of our interest in BHG would adversely affect our noninterest income. Moreover, there are certain limitations on our ability to sell our interest in BHG without first offering BHG and the other members a right of first refusal, and, upon the closing of the additional investment, we will be prohibited from transferring any portion of our interest without the consent of the other members of BHG for five years, other than transfers in connection with an acquisition of Pinnacle Financial or Pinnacle Bank or as a result of a change in applicable law that forces us and/or Pinnacle Bank to divest our or Pinnacle Bank's ownership interests in BHG.

A significant portion of BHG's revenue (and correspondingly our interest in any of BHG's net profits) comes from the sale of loans originated by BHG to community banks. Moreover, the purchase price we paid to acquire our interest in BHG (including the amount we agreed to pay in connection with the additional investment) was based on our expectation that BHG will continue to grow its business and increase the amount of loans that it is able to originate and sell.  In the event that BHG's loan growth slows over historical levels or its loan sales decrease (including as a result of regulatory restrictions on banks that are the principal purchasers of BHG's loans), its results of operations and our non-interest income would be adversely affected.  BHG currently operates in most states without the need for a permit or any other license.  In the event that BHG was required to register or become licensed in any state in which it operates, or regulations are adopted that seek to limit BHG's ability to operate in any jurisdiction or that seek to limit the amounts of interest that BHG can charge on its loans, BHG's results of operations (and our and Pinnacle Bank's interest in BHG's net profits) could be materially and adversely affected.

BHG's business, while not regulated directly by any federal bank regulators, may become subject to increased scrutiny as it grows or as a result of our investment. The FDIC has published guidance related to the operation of marketplace lenders and banks' business relationship with such lenders. Were BHG to become subject to direct regulation by any state or federal banking regulators, its compliance costs may increase and its loan yields may be negatively impacted, which would negatively impact its results of operations and our and Pinnacle Bank's interest in BHG's net profits. Were banks that are examined by the FDIC restricted in their ability to buy loans originated by BHG, BHG's business would be negatively impacted, which would negatively impact our interest in BHG's profits.

Our loan portfolio includes a meaningful amount of real estate construction and development loans, which have a greater credit risk than residential mortgage loans.

Although we have made meaningful progress over the last three years in reducing our concentration of real estate construction and development loans, the percentage of these loans in Pinnacle Bank's portfolio was approximately 11.4% of total loans at December 31, 2015. These loans make up approximately 25.9% of our non-performing loans at December 31, 2015. This type of lending is generally considered to have relatively high credit risks because the principal is concentrated in a limited number of loans with repayment dependent on the successful completion and operation of the related real estate project. The credit quality of many of these loans deteriorated during the challenging economic period of 2008 to 2012 due to the adverse conditions in the real estate market during that period and that type of deterioration could occur again. Weakness in residential real estate market prices as well as demand could result in price reductions in home and land values adversely affecting the value of collateral securing the construction and development loans that we hold. Should we experience the return of these adverse economic and real estate market conditions we may again experience increases in non-performing loans and other real estate owned, increased losses and expenses from the management and disposition of non-performing assets, increases in provision for loan losses, and increases in operating expenses as a result of the allocation of management time and resources to the collection and work out of loans, all of which would negatively impact our financial condition and results of operations.

Changes to capital requirements for bank holding companies and depository institutions that became effective January 1, 2015 and continue to be phased in may negatively impact Pinnacle Financial's and Pinnacle Bank's results of operations.

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, which became effective on January 1, 2015, implement the Basel III regulatory capital reforms 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 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 risk-based 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); and (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 beginning January 1, 2016) 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 being phased in at 0.625% of risk-weighted assets in 2016 and will increase by a like amount each year until fully implemented in January 2019. We will be subject to limitations on paying dividends, engaging in share repurchases and paying discretionary bonuses if our capital levels fall below these minimums 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 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, 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 at that date, trust preferred securities issued prior to that date, 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 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 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. Both Pinnacle Financial and Pinnacle Bank opted-out of this requirement.

The application of more stringent capital requirements for Pinnacle Financial and Pinnacle Bank, like those adopted to implement the Basel III reforms, could, among other things, result in lower returns on invested capital, require the raising of additional capital, (like the subordinated notes we issued in connection with our mergers with CapitalMark and Magna) and result in regulatory actions if we were to be unable to comply with such requirements.  Furthermore, the imposition of liquidity requirements in connection with the implementation of Basel III could result in our having to lengthen the term of our funding, restructure our business models and/or increase our holdings of liquid assets.

Implementation of changes to asset risk weightings for risk based capital calculations, items included or deducted in calculating regulatory capital and/or additional capital conservation buffers could result in management modifying its business strategy and could limit our ability to make distributions, including paying dividends or buying back shares.

We are dependent on our information technology and telecommunications systems and third-party servicers, and systems failures, interruptions or breaches of security could have an adverse effect on our financial condition and results of operations.

Our operations rely on the secure processing, storage and transmission of confidential and other information in our computer systems and networks. Although we take protective measures and endeavor to modify these systems as circumstances warrant, the security of our computer systems, software and networks may be vulnerable to breaches, unauthorized access, misuse, computer viruses or other malicious code and other events that could have a security impact.  We outsource many of our major systems, such as data processing, loan servicing and deposit processing systems. The failure of these systems, or the termination of a third-party software license or service agreement on which any of these systems is based, could interrupt our operations. Because our information technology and telecommunications systems interface with and depend on third-party systems, we could experience service denials if demand for such services exceeds capacity or such third-party systems fail or experience interruptions. If sustained or repeated, a system failure or service denial could result in a deterioration of our ability to process new and renewal loans, gather deposits and provide customer service, compromise our ability to operate effectively, damage our reputation, result in a loss of customer business and/or subject us to additional regulatory scrutiny and possible financial liability, any of which could have a material adverse effect on our financial condition and results of operations.

In addition, we provide our customers the ability to bank remotely, including over the Internet or through their mobile device. The secure transmission of confidential information is a critical element of remote and mobile banking. Our network could be vulnerable to unauthorized access, computer viruses, phishing schemes, spam attacks, human error, natural disasters, power loss and other security breaches. We may be required to spend significant capital and other resources to protect against the threat of security breaches and computer viruses, or to alleviate problems caused by security breaches or viruses. To the extent that our activities or the activities of our customers involve the storage and transmission of confidential information, security breaches (including breaches of security of customer systems and networks) and viruses could expose us to claims, litigation and other possible liabilities. Any inability to prevent security breaches or computer viruses could also cause existing customers to lose confidence in our systems and could adversely affect our reputation, results of operations and ability to attract and maintain customers and businesses. In addition, a security breach could also subject us to additional regulatory scrutiny, expose us to civil litigation and possible financial liability and cause reputational damage.

Environmental liability associated with commercial lending could result in losses.

In the course of business, Pinnacle Bank may acquire, through foreclosure, or deed in lieu of foreclosure, properties securing loans it has originated or purchased which are in default. Particularly in commercial real estate lending, there is a risk that hazardous substances could be discovered on these properties. In this event, we, or Pinnacle Bank, might be required to remove these substances from the affected properties at our sole cost and expense. The cost of this removal could substantially exceed the value of affected properties. We may not have adequate remedies against the prior owner or other responsible parties and could find it difficult or impossible to sell the affected properties. These events could have a material adverse effect on our business, results of operations and financial condition.

National or state legislation or regulation may increase our expenses and reduce earnings.

Bank regulators are increasing regulatory scrutiny, and additional restrictions (including those originating from the Dodd-Frank Act) on financial institutions have been proposed or adopted by regulators and by Congress. Changes in tax law, federal legislation, regulation or policies, such as bankruptcy laws, deposit insurance, consumer protection laws, and capital requirements, among others, can result in significant increases in our expenses and/or charge-offs, which may adversely affect our earnings. Changes in state or federal tax laws or regulations can have a similar impact. State and municipal governments, including the State of Tennessee, could seek to increase their tax revenues through increased tax levies which could have a meaningful impact on our results of operations.  Furthermore, financial institution regulatory agencies are expected to continue to be very aggressive in responding to concerns and trends identified in examinations, including the continued issuance of additional formal or informal enforcement or supervisory actions.   These actions, whether formal or informal, could result in our agreeing to limitations or to take actions that limit our operational flexibility, restrict our growth or increase our capital or liquidity levels. Failure to comply with any formal or informal regulatory restrictions, including informal supervisory actions, could lead to further regulatory enforcement actions. Negative developments in the financial services industry and the impact of recently enacted or new legislation in response to those developments could negatively impact our operations by restricting our business operations, including our ability to originate or sell loans, and adversely impact our financial performance. In addition, industry, legislative or regulatory developments may cause us to materially change our existing strategic direction, capital strategies, compensation or operating plans.

Our ability to maintain required capital levels and adequate sources of funding and liquidity could be impacted by changes in the capital markets and deteriorating economic and market conditions.

We, and Pinnacle Bank, are required to maintain certain capital levels established by banking regulations or specified by bank regulators, including those capital maintenance standards imposed on us as a result of the Dodd-Frank Act, and we are required to serve as a source of strength to Pinnacle Bank. We must also maintain adequate funding sources in the normal course of business to support our operations and fund outstanding liabilities. Our ability to maintain capital levels, sources of funding and liquidity could be impacted by changes in the capital markets in which we operate and deteriorating economic and market conditions. Pinnacle Bank is required to obtain regulatory approval in order to pay dividends to us unless the amount of such dividends does not exceed its net income for that calendar year plus retained net income for the preceding two years. Any restriction on the ability of Pinnacle Bank to pay dividends to us could impact our ability to continue to pay dividends on our common stock. Moreover, failure by our bank subsidiary to meet applicable capital guidelines or to satisfy certain other regulatory requirements could subject our bank subsidiary to a variety of enforcement remedies available to the federal regulatory authorities.

Certain of our deposits and other funding sources may be volatile and impact our liquidity.

In addition to the traditional core deposits, such as demand deposit accounts, interest checking, money market savings and certificates of deposits less than $250,000, we utilize or in the past have utilized several noncore funding sources, such as brokered certificates of deposit, Federal Home Loan Bank (FHLB) of Cincinnati advances, federal funds purchased and other sources. We utilize these noncore funding sources to fund the ongoing operations and growth of Pinnacle Bank. The availability of these noncore funding sources is subject to broad economic conditions and to investor assessment of our financial strength and, as such, the cost of funds may fluctuate significantly and/or be restricted, thus impacting our net interest income, our immediate liquidity and/or our access to additional liquidity. We have somewhat similar risks to the extent high balance core deposits exceed the amount of deposit insurance coverage available.

We impose certain internal limits as to the absolute level of noncore funding we will incur at any point in time. Should we exceed those limitations, we may need to modify our growth plans, liquidate certain assets, participate loans to correspondents or execute other actions to allow for us to return to an acceptable level of noncore funding within a reasonable amount of time.

If the federal funds and interbank funding rates remain at current extremely low levels, our net interest margin, and consequently our net earnings, may be negatively impacted .

Because of significant competitive pressures in our market and the negative impact of these pressures on our deposit and loan pricing, coupled with the fact that a significant portion of our loan portfolio has variable rate pricing that moves in concert with changes to the Federal Reserve Board of Governors' federal funds rate or the London Interbank Offered Rate (LIBOR) (both of which are at extremely low levels as a result of current economic conditions), our net interest margin may be negatively impacted. Additionally, the amount of non-accrual loans and other real estate owned has been and may continue to be elevated. We also expect loan pricing to remain competitive in 2016 and believe that economic factors affecting broader markets will likely result in reduced yields for our investment securities portfolio.  As a result, our net interest margin, and consequently our profitability, may continue to be negatively impacted in 2016 and beyond.

A decline in our stock price or expected future cash flows, or a material adverse change in our results of operations or prospects, could result in impairment of our goodwill.

A significant and sustained decline in our stock price and market capitalization below book value, a significant decline in our expected future cash flows, a significant adverse change in the business climate, slower growth rates or other factors could result in impairment of our goodwill. At December 31, 2015, our goodwill and other identifiable intangible assets totaled approximately $442.8 million. If we were to conclude that a write-down of our goodwill is necessary, then the appropriate charge would likely cause a material loss. Any significant loss would further adversely impact the capacity of Pinnacle Bank to pay dividends to us without seeking prior regulatory approval, which could adversely affect our ability to pay required interest payments.

Competition with other banking institutions could adversely affect our profitability.

A number of banking institutions in our geographic markets have higher lending limits, more banking offices, and a larger market share of loans or deposits than we do. In addition, our asset management division competes with numerous brokerage firms and mutual fund companies which are also much larger. In some respects, this may place these competitors in a competitive advantage. This competition may limit or reduce our profitability, reduce our growth and adversely affect our results of operations and financial condition.

Inability to retain senior management and key employees or to attract new experienced financial services professionals could impair our relationship with our customers, reduce growth and adversely affect our business.

We have assembled a senior management team which has substantial background and experience in banking and financial services in the Nashville, Knoxville, Memphis and Chattanooga markets. Moreover, much of our organic loan growth in 2012 through 2015 was the result of our ability to attract experienced financial services professionals who have been able to attract customers from other financial institutions.  Inability to retain these key personnel (including key personnel of CapitalMark or Magna) or to continue to attract experienced lenders with established books of business could negatively impact our growth because of the loss of these individuals' skills and customer relationships and/or the potential difficulty of promptly replacing them.

We are subject to certain litigation, and our expenses related to this litigation may adversely affect our results.

We are from time to time subject to certain litigation in the ordinary course of our business. These claims and legal actions, including supervisory actions by our regulators, could involve large monetary claims and significant defense costs. The outcome of these cases is uncertain. Substantial legal liability or significant regulatory action against us could have material adverse financial effects or cause significant reputational harm to us, which in turn could seriously harm our business prospects.

We may issue additional common stock or other equity securities in the future which could dilute the ownership interest of existing shareholders.

In order to maintain our or Pinnacle Bank's capital at desired or regulatory-required levels, we may issue additional shares of common stock, or securities convertible into, exchangeable for or representing rights to acquire shares of common stock. We may sell these shares at prices below the current market price of shares, and the sale of these shares may significantly dilute shareholder ownership. We could also issue additional shares in connection with acquisitions of other financial institutions or investments in fee-related businesses such as BHG, which would also dilute shareholder ownership.

Even though our common stock is currently traded on the Nasdaq Stock Market's Global Select Market, it has less liquidity than many other stocks quoted on a national securities exchange.

The trading volume in our common stock on the Nasdaq Global Select Market has been relatively low when compared with larger companies listed on the Nasdaq Global Select Market or other stock exchanges.  Although we have experienced increased liquidity in our stock, we cannot say with any certainty that a more active and liquid trading market for our common stock will continue to develop. Because of this, it may be more difficult for stockholders to sell a substantial number of shares for the same price at which stockholders could sell a smaller number of shares.

We cannot predict the effect, if any, that future sales of our common stock in the market, or the availability of shares of common stock for sale in the market, will have on the market price of our common stock. We can give no assurance that sales of substantial amounts of common stock in the market, or the potential for large amounts of sales in the market, would not cause the price of our common stock to decline or impair our future ability to raise capital through sales of our common stock.

The market price of our common stock has fluctuated significantly, and may fluctuate in the future. These fluctuations may be unrelated to our performance. General market or industry price declines or overall market volatility in the future could adversely affect the price of our common stock, and the current market price may not be indicative of future market prices.

Holders of Pinnacle Financial's and Pinnacle Bank's indebtedness and junior subordinated debentures have rights that are senior to those of Pinnacle Financial's stockholders.

Pinnacle Financial has issued trust preferred securities from special purpose trusts and accompanying junior subordinated debentures. At December 31, 2015, Pinnacle Financial had outstanding trust preferred securities and accompanying junior subordinated debentures totaling $82.5 million. Payments of the principal and interest on the trust preferred securities of these trusts are conditionally guaranteed by Pinnacle Financial. Further, the accompanying junior subordinated debentures Pinnacle Financial issued to the trusts are senior to Pinnacle Financial's shares of common stock. As a result, Pinnacle Financial must make payments on the junior subordinated debentures before any dividends can be paid on common stock and, in the event of Pinnacle Financial's bankruptcy, dissolution or liquidation, the holders of the junior subordinated debentures must be satisfied before any distributions can be made on Pinnacle Financial's common stock. Pinnacle Financial has the right to defer distributions on its junior subordinated debentures (and the related trust preferred securities) for up to five years, during which time no dividends may be paid on its common stock. If our financial condition deteriorates or if we do not receive required regulatory approvals, we may be required to defer distributions on our junior subordinated debentures.

On July 30, 2015, Pinnacle Bank issued $60 million of subordinated notes due July 30, 2025 in a private placement to certain institutional accredited investors. These notes are obligations of Pinnacle Bank, and not Pinnacle Financial, and the notes rank senior to shares of Pinnacle Bank's common stock, all of which are owned by Pinnacle Financial.  In the event of a liquidation or winding up of Pinnacle Bank, these notes, along with Pinnacle Bank's other indebtedness, would have to be repaid before Pinnacle Financial and its shareholders would be entitled to receive any of the assets of Pinnacle Bank.

Upon consummation of the proposed merger with Avenue, Pinnacle Financial will assume Avenue's obligations under its outstanding $20.0 million subordinated notes issued in December 2014 that mature in December 2024. These notes bear interest at a rate of 6.75% per annum until January 1, 2020 and may not be repaid prior to such date. Beginning on January 1, 2020, if not redeemed on such date, these notes will bear interest at a floating rate equal to the three-month LIBOR determined on the determination date of the applicable interest period plus 495 basis points. The terms of these notes will prohibit Pinnacle Financial from declaring or paying any dividends or distributions on its common stock or redeeming, purchasing, acquiring or making a principal payment on these notes, at any time when payment of interest on these notes has not been timely made and while any such accrued and unpaid interest remains unpaid. Moreover, the notes will rank senior to shares of Pinnacle Financial's common stock. In the event of a liquidation or winding up of Pinnacle Financial, these notes, along with Pinnacle Financial's other indebtedness, would have to be repaid before Pinnacle Financial's shareholders would be entitled to receive any of the assets of Pinnacle Financial.

Pinnacle Financial or Pinnacle Bank may from time to time issue additional subordinated indebtedness that would have to be repaid before Pinnacle Financial's shareholders would be entitled to receive any of the assets of Pinnacle Financial or Pinnacle Bank.

Our business is dependent on technology, and an inability to invest in technological improvements may adversely affect our results of operations and financial condition.

The financial services industry is undergoing rapid technological changes with frequent introductions of new technology-driven products and services. In addition to better serving customers, the effective use of technology increases efficiency and enables financial institutions to reduce costs. We have made significant investments in data processing, management information systems and internet banking accessibility. Our future success will depend in part upon our ability to create additional efficiencies in our operations through the use of technology. Many of our competitors have substantially greater resources to invest in technological improvements. We cannot make assurances that our technological improvements will increase our operational efficiency or that we will be able to effectively implement new technology-driven products and services or be successful in marketing these products and services to our customers.

We are subject to various statutes and regulations that may impose additional costs or limit our ability to take certain actions.

We operate in a highly regulated industry and are subject to examination, supervision, and comprehensive regulation by various regulatory agencies. Our compliance with these regulations is costly and restricts certain of our activities, including payment of dividends, mergers and acquisitions, investments, loans and interest rates charged on loans, interest rates paid on deposits and locations of offices. We are also subject to capital requirements established by our regulators, which require us to maintain specified levels of capital. It is possible that our FDIC assessments may increase in the future. Any future assessment increases could negatively impact our results of operations. Significant changes in laws and regulations applicable to the banking industry have been recently adopted and others are being considered in Congress.  We cannot predict the effects of these changes on our business and profitability. Because government regulation greatly affects the business and financial results of commercial banks and bank holding companies, our cost of compliance could adversely affect our ability to operate profitably.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following is a discussion of our financial condition at December 31, 2015 and 2014 and our results of operations for each of the years in the three-year period ended December 31, 2015.  The purpose of this discussion is to focus on information about our financial condition and results of operations which is not otherwise apparent from the consolidated financial statements.  The following discussion and analysis should be read along with our consolidated financial statements and the related notes included elsewhere herein.

Overview

General. Our fully diluted net income per common share for the year ended December 31, 2015 was $2.52 compared to fully diluted net income  per common share of $2.01 and $1.67 for the years ended December 31, 2014 and 2013, respectively.  At December 31, 2015, loans had increased by $1.953 billion as compared to the end of 2014.

We acquired a 30% membership interest in Bankers Healthcare Group, LLC (BHG) on February 1, 2015 for $75.0 million. We acquired CapitalMark Bank and Trust (CapitalMark) on July 31, 2015 and Magna Bank (Magna) on September 1, 2015. At the acquisition date, CapitalMark had net assets of $67.6 million, including loans of $857.3 million and deposits valued at $953.2 million. At the acquisition date, Magna had net assets of $51.9 million, including loans of $442.0 million and deposits valued at $452.7 million. These acquisitions further expand the Pinnacle footprint into East and West Tennessee.

Results of operations. Our results of operations for 2015 include the impact of our acquired entities for the period between their respective acquisition dates and December 31, 2015. Our net interest income increased to $236.6 million for 2015 compared to $193.0 million for 2014 and $175.9 million for 2013. The net interest margin (the ratio of net interest income to average earning assets) for 2015 was 3.72% compared to 3.75% and 3.77% for 2014 and 2013, respectively.  Our net interest margin for all periods presented reflects the contraction in our earning asset yields, which is primarily attributable to reduced yields in our securities portfolio.

Our provision for loan losses was $9.2 million for 2015 compared to $3.6 million in 2014 and $7.9 million in 2013. Our net charge-offs were $11.1 million during 2015 compared to $4.2 million in 2014 and $9.3 million in 2013. During 2015, we decreased our allowance for loan losses as a percentage of loans from 1.47% at December 31, 2014 to 1.00% at December 31, 2015. The overall methodology used to estimate the allowance for loan losses for legacy Pinnacle loans is consistent with prior periods ; however,  the allowance for loan losses at each of  CapitalMark and Magna was eliminated as a component of purchase accounting as these entities' loans were recorded at fair value upon acquisition. As such, the allowance as a percentage of total loans decreased significantly between December 31, 2014 and December 31, 2015. For purchased loans, the allowance for loan losses subsequent to the acquisition date is similar to that utilized for legacy Pinnacle loans. Our accounting policy is to compare the computed allowance for loan losses on purchased loans to the remaining fair value adjustment at the individual loan level. If the computed allowance is greater than the remaining fair value adjustment, the excess is added to the allowance for loan losses by a provision for loan losses.

Noninterest income for 2015 compared to 2014 increased by $33.9 million, or 64.5%. The increase was primarily due to income from our 30% equity method investment in BHG, which was $20.6 million for the year ended December 31, 2015. The additional growth was attributable to increased interchange revenues as well as increased production in our fee-based products such as investments, insurance and trust. Noninterest income for 2014 compared to 2013 increased by $5.5 million, or 11.7%, which was primarily attributable to increased interchange revenues as well as increased production in our fee-based products such as investments, insurance and trust.

Noninterest expense for 2015 compared to 2014 increased by $34.6 million, or 25.4%, primarily due to an increase in salaries and employee benefits expense. Salaries and employee benefits expense increased $17.6 million, resulting from annual merit increases awarded in the first quarter of 2015, new hires resulting from our organic growth and mergers with CapitalMark and Magna and the overall increase in our associate base. Pinnacle Financial had 1,058.5 full-time equivalent employees at December 31, 2015 and has identified approximately 40 positions that are slated for elimination after the technology conversion is completed at CapitalMark, which we expect to occur in the first quarter of 2016. We also realized increases in equipment and occupancy costs due to our mergers with CapitalMark and Magna, partly offset by decreased other real estate owned expense.   Merger expenses accounted for approximately $4.8 million of expenses in 2015.  Noninterest expense for 2014 compared to 2013 increased by $7.0 million, or 5.5%, primarily due to an increase in salaries and employee benefits expense, which increased by $5.7 million. We also had higher equipment and occupancy costs due to the expansion of our corporate headquarters in Nashville, TN as well as the addition of an office in Knoxville, TN during the fourth quarter of 2014. These increases were partly offset by decreased other real estate owned expense. The number of full-time equivalent employees increased from 751.0 at December 31, 2013 to 764.0 at December 31, 2014 and 1,058.5 at December 31, 2015.

During the three years ended December 31, 2015, 2014 and 2013, Pinnacle Financial recorded income tax expense of $47.6 million, $35.2 million and $28.2 million, respectively. Pinnacle's effective tax rate for the three years ended December 31, 2015, 2014 and 2013, was 33.3%, 33.3% and 32.8%, respectively, and differs from the combined federal and state income statutory rate primarily due to a state excise tax expense, investments in bank qualified municipal securities, our real estate investment trust, participation in the Community Investment Tax Credit (CITC) program, bank owned life insurance and tax savings from our captive insurance subsidiary, PNFP Insurance, Inc. offset in part by the limitation on deductibility of meals and entertainment expense.

Our efficiency ratio (the ratio of noninterest expense to the sum of net interest income and noninterest income) was 52.9%, 55.5% and 58.0% for the three years ended December 31, 2015, 2014 and 2013, respectively. The efficiency ratio measures the amount of expense that is incurred to generate a dollar of revenue.

Net income for 2015 was $95.5 million compared to $70.5 million in net income in 2014 and $57.7 million in 2013.  Fully-diluted net income per common share available to common stockholders was $2.52 for 2015 compared to $2.01 for 2014 and $1.67 for 2013.

Financial Condition. Our loan balances increased by $1.953 billion during 2015 compared to an increase of $445.5 million in 2014. Our loan balances increased by $1.299 billion upon the acquisition of CapitalMark and Magna.  The remaining increase in 2015 is attributable to a growing economy in the Middle Tennessee market, increases in the number of relationship advisors in our other markets and increased focus on attracting new customers to our Company.

Total deposits increased from $4.783 billion at December 31, 2014 to $6.971 billion at December 31, 2015.  Within our deposits, the ratio of core funding to total deposits decreased slightly from 84.8% at December 31, 2014 to 84.5% at December 31, 2015. Our deposit balances increased $1.406 billion upon the acquisition of CapitalMark and Magna. The remaining increase in 2015 is attributable to a growing economy in the Middle Tennessee market and increases in the number of relationship advisors in our other markets.

We believe we have hired experienced relationship managers that have significant client portfolios and longstanding reputations within the communities we serve.  As such, we believe they will attract more relationship managers to our firm as well as loans and deposits from new and existing small-and middle-market clients as the economies in our principal markets continue to expand.

Capital and Liquidity. At December 31, 2015 and 2014, our capital ratios, including our bank's capital ratios, exceeded regulatory minimum capital requirements and we would be considered "well capitalized" pursuant to regulatory requirements.  From time to time we may be required to support the capital needs of our bank subsidiary. At December 31, 2015, we had approximately $21.7 million of cash at the holding company which could be used to support our bank. We believe we and our bank subsidiary have various capital raising techniques available to provide for the capital needs of our bank, if necessary.

Critical Accounting Estimates

The accounting principles we follow and our methods of applying these principles conform with U.S. generally accepted accounting principles and with general practices within the banking industry.  In connection with the application of those principles, we have made judgments and estimates which, in the case of the determination of our allowance for loan losses, the valuation of other real estate owned, the assessment of the valuation of deferred tax assets and the assessment of impairment of intangibles, has been critical to the determination of our financial position and results of operations.

Allowance for Loan Losses (allowance). Our management assesses the adequacy of the allowance prior to the end of each calendar quarter. This assessment includes procedures to estimate the allowance and test the adequacy and appropriateness of the resulting balance. The level of the allowance is based upon management's evaluation of the loan portfolio, loan loss experience, asset quality trends, known and inherent risks in the portfolio, adverse situations that may affect the borrowers' ability to repay the loan (including the timing of future payment), the estimated value of any underlying collateral, composition of the loan portfolio, economic conditions, industry and peer bank loan quality indications and other pertinent factors, including regulatory recommendations.  The level of allowance maintained is believed by management to be adequate to absorb probable losses inherent in the loan portfolio at the balance sheet date. The allowance is increased by provisions charged to expense and decreased by charge-offs, net of recoveries of amounts previously charged-off.  Allocation of the allowance may be made for specific loans, but the entire allowance is available for any loan that, in management's judgment, is deemed to be uncollectible.

In assessing the adequacy of the allowance, we also consider the results of our ongoing independent loan review process. We undertake this process both to ascertain those loans in the portfolio with elevated credit risk and to assist in our overall evaluation of the risk characteristics of the entire loan portfolio.  Our loan review process includes the judgment of management, independent internal loan reviewers, and reviews that may have been conducted by third-party reviewers primarily regulatory examiners. We incorporate relevant loan review results in the allowance.

The ASC 450-20 component of the allowance for loan losses begins with a migration analysis based on our internal system of risk rating, if applicable, and historical loss data in our portfolio, by loan type. The migration analysis accumulates losses realized over a rolling four-quarter cycle and is utilized to determine an annual loss rate for each category for each quarter-end in our look-back period. The look-back period in our migration analysis includes 24 quarters as we believe this period is representative of an economic cycle. The loss rates for each category are then averaged and applied to the end of period loan portfolio balances to determine estimated losses.  The estimated losses by category are then adjusted by a specifically-determined loss emergence period for each type of loan in our portfolio. A loss emergence period represents the length of time from the initial event which triggered the loss to the recognition of the loss by Pinnacle Bank. Combined, th e loss rates and loss emergence period provide a quantitative estimate of credit losses inherent in our end of period loan portfolio based on our actual loss experience.

The estimated loan loss allocation for all loan segments also considers management's estimate of probable losses for a number of qualitative factors that have not been considered in the loan migration analysis. The qualitative categories and the measurements used to quantify the risks within each of these categories are subjectively selected by management, but measured by objective measurements period over period.  The data for each measurement may be obtained from internal or external sources.  The current period measurements are evaluated and assigned a factor commensurate with the current level of risk relative to past measurements over time. The resulting factor is applied to the non-impaired loan portfolio.  This amount represents estimated probable inherent credit losses which exist, but have not yet been identified either in our risk rating or impairment process, as of the balance sheet date, and is based upon quarterly trend assessments in portfolio concentrations, policy exceptions, economic conditions, lending staff performance, independent loan review results, collateral considerations, credit quality, competition and regulatory requirements, enterprise wide risk assessments, and peer group credit quality. The qualitative allowance allocation, as determined by the processes noted above, is increased or decreased for each loan segment based on the assessment of these various qualitative factors.

The allowance for loan losses for purchased loans is calculated similar to that utilized for legacy Pinnacle loans. Our accounting policy is to compare the computed allowance for loan losses for purchased loans to any remaining fair value adjustment on a loan-by-loan basis. If the computed allowance is greater than the remaining fair value adjustment, the excess is added to the allowance for loan losses by a provision for loan losses.

The ASC 450-20 portion of the allowance also includes a small unallocated component.  We believe that the unallocated amount is warranted for inherent factors that cannot be practically assigned to individual loan categories, such as the imprecision in the overall loss allocation measurement process, the subjectivity risk of not considering all relevant environmental categories and related measurements and imprecision in our credit risk ratings process.  The appropriateness of the unallocated component of the allowance is assessed each quarter end based on upon changes in the overall business environment not otherwise captured.

The second component of the allowance for loan losses is determined pursuant to ASC 310-10-35. Loans are impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due according to the contractual terms of the loan agreement. Collection of all amounts due according to the contractual terms means collecting all interest and principal payments of a loan as scheduled in the loan agreement. This evaluation is inherently subjective as it requires material estimates including the amounts and timing of future cash flows expected to be received on impaired loans that may be susceptible to significant change. Loan losses are charged off when management believes that the full collectability of the loan is unlikely. A loan may be partially charged-off after a "confirming event" has occurred which serves to validate that full repayment pursuant to the terms of the loan is unlikely.

An impairment allowance is recognized if the fair value of the loan is less than the recorded investment in the loan (recorded investment in the loan is the principal balance plus any accrued interest, net of deferred loan fees or costs and unamortized premium or discount). The impairment is recognized through the provision for loan losses and is a component of the allowance. Loans that are impaired are recorded at the present value of expected future cash flows discounted at the loan's effective interest rate, or if the loan is collateral dependent, at the fair value of the collateral, less estimated disposal costs. If the loan is collateral dependent, the principal balance of the loan is charged-off in an amount equal to the impairment measurement. The fair value of collateral dependent loans is derived primarily from collateral appraisals performed by independent third-party appraisers.  Management believes it follows appropriate accounting and regulatory guidance in determining impairment and accrual status of impaired loans.

Pursuant to the guidance set forth in ASU No. 2011-02, A Creditor's Determination of Whether a Restructuring is a Troubled Debt Restructuring, the above impairment methodology is also applied to those loans identified as troubled debt restructurings.

We then test the resulting allowance by comparing the balance in the allowance to historical trends and industry and peer information. Our management then evaluates the result of the procedures performed, including the results of our testing, and decides on the appropriateness of the balance of the allowance in its entirety. The audit committee of our board of directors approves the allowance for loan loss policy annually and reviews the methodology and approves the resultant allowance prior to the filing of quarterly and annual financial information.

While our policies and procedures used to estimate the allowance for loan losses, as well as the resultant provision for loan losses charged to operations, are considered adequate by management and are reviewed from time to time by our regulators, they are necessarily approximate and inherently imprecise. There are factors beyond our control, such as conditions in the local, national, and international economy, a local real estate market or particular industry conditions which may negatively impact materially our asset quality and the adequacy of our allowance for loan losses and thus the resulting provision for loan losses.

Other Real Estate Owned. Other real estate owned (OREO), which consists of properties obtained through foreclosure or through deed in lieu of foreclosure in satisfaction of loans, is reported 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 downward valuation adjustments are determined on a specific property basis and are included as a component of other noninterest expense along with holding costs. The fair value of other real estate owned is derived primarily from independent appraisers. Our internal policies generally require OREO properties to be appraised annually.  Any net gains or losses on disposal realized at the time of disposal are reflected, net, in noninterest income or noninterest expense, as applicable.  Significant judgments and complex estimates are required in estimating the fair value of other real estate owned, and the period of time within which such estimates can be considered current is significantly shortened during periods of market volatility. As a result, the net proceeds realized from sales transactions could differ significantly from appraisals, comparable sales, and other estimates used to determine the fair value of other real estate owned.

Impairment of Intangible Assets. Long-lived assets, including purchased intangible assets such as our core deposit intangible asset subject to amortization as well as intangible assets recorded as a component of our equity method investment in BHG are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of would be separately presented in the balance sheet and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. There are no such assets to be disposed of at December 31, 2015.

Goodwill is evaluated for impairment annually and more frequently if events and circumstances indicate that the asset might be impaired.  Our annual assessment date is September 30.  An impairment loss is recognized to the extent that the carrying amount exceeds the asset's fair value.

ASC 350, Intangibles — Goodwill and Other , provides authoritative guidance related to testing goodwill for impairment, including embedded goodwill recorded as a component of our equity method investment in BHG. The standard provides an entity the option to first perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If an entity does a qualitative assessment and determines it is necessary, or if a qualitative assessment is not performed, it is required to perform a two-step goodwill impairment test to identify potential goodwill impairment and measure the amount of goodwill impairment loss to be recognized for that reporting unit (if any). If, based on a qualitative assessment, an entity determines that the fair value of a reporting unit is more than its carrying amount, the two-step goodwill impairment test is not required. The results of our qualitative assessment indicated that the fair value of our reporting unit was more than its carrying value, and accordingly, the two-step goodwill impairment test was not performed.

Should our common stock price decline or other impairment indicators become known, additional impairment testing of goodwill may be required. Should it be determined in a future period that the goodwill has become impaired, then a charge to earnings will be recorded in the period such determination is made. While we believe that the assumptions utilized in our testing were appropriate, they may not reflect actual outcomes that could occur.  Specific factors that could negatively impact the assumptions used include the following: a change in the control premium being realized in the market or a meaningful change in the number of mergers and acquisitions occurring; the amount of expense savings that may be realized in an acquisition scenario;  significant fluctuations in our asset/liability balances or the composition of our balance sheet; a change in the overall valuation of the stock market, specifically bank stocks; performance of Southeast U.S. Banks; and Pinnacle Financial's performance relative to peers.  Changing these assumptions, or any other key assumptions, could have a material impact on the amount of goodwill impairment, if any.

Net Interest Income. Net interest income represents the amount by which interest earned on various earning assets exceeds interest paid on deposits and other interest bearing liabilities and is the most significant component of our revenues. For the year ended December 31, 2015, we recorded net interest income of approximately $236.6 million, which resulted in a net interest margin (net interest income divided by the average balance of interest earning assets) of 3.72%.  For the year ended December 31, 2014, we recorded net interest income of approximately $193.0 million, which resulted in a net interest margin of 3.75%. For the year ended December 31, 2013, we recorded net interest income of approximately $175.9 million, which resulted in a net interest margin of 3.77%.

The following table sets forth the amount of our average balances, interest income or interest expense for each category of interest-earning assets and interest-bearing liabilities and the average interest rate for total interest-earning assets and total interest-bearing liabilities, net interest spread and net interest margin for each of the years in the three-year period ended December 31, 2015 (in thousands):

Net interest spread (3)							3.55	%							3.65	%							3.65	%
Net interest margin (4)							3.72	%							3.75	%							3.77	%

For the year ended December 31, 2015, our net interest spread was 3.55%, while the net interest margin was 3.72% compared to a net interest spread of 3.65% for each of the years ended December 31, 2014 and 2013, and a net interest margin of 3.75% and 3.77%, respectively. The net interest margin has been greatly impacted by management's efforts to increase low cost customer deposits and increase loan volumes.  Our loan yields grew only slightly between 2015 and 2014 as the competition for quality loans continues to be intense and the market dictates the rate necessary to grow volumes. During the year ended December 31, 2015, total deposit and liabilities funding rates were more than those rates for the year ended December 31, 2014 by 3 basis points and were less than those rates for the year ended December 31, 2013 by 4 basis points.  The net increase in 2015 when compared to 2014 was the result of increased rates in our savings and money market deposits and the rate paid on our increased balance of subordinated debt and other borrowings offset in part by a reduction of the rate paid on FHLB borrowings.

We continue to deploy various asset liability management strategies to manage our risk to interest rate fluctuations.  We believe margin expansion over both the short and the long term will be challenging due to continued pressure on earning asset yields during this extended period of a low interest rates. Loan pricing for creditworthy borrowers is very competitive in our markets and has limited our ability to increase pricing on new and renewed loans over the last several quarters. We anticipate that this challenging competitive environment will continue in 2016. However, we believe our net interest income should increase in 2016 compared to 2015 primarily due to an increase in average earning asset volumes, primarily loans as well as the incremental amounts attributable for CapitalMark and Magna. We anticipate funding these increased earning assets by continuing to grow our core deposits, with wholesale funding limited to that required to fund the shortfall, if any.

Rate and Volume Analysis. Net interest income increased by $43.6 million between the years ended December 31, 2014 and 2015 and by $17.1 million between the years ended December 31, 2013 and 2014. The following is an analysis of the changes in our net interest income comparing the changes attributable to rates and those attributable to volumes (in thousands):

Net interest income		$	(664	)		$	47,169			$	43,647			$	(2,418	)		$	19,714			$	17,086

Changes in net interest income are attributed to either changes in average balances (volume change) or changes in average rates (rate change) for earning assets and sources of funds on which interest is received or paid.  Volume change is calculated as change in volume times the previous rate while rate change is change in rate times the previous volume.  The change attributed to rates and volumes (change in rate times change in volume) is considered above as a change in volume.

Provision for Loan Losses. The provision for loan losses represents a charge to earnings necessary to establish an allowance for loan losses that, in our management's evaluation, we believe to be adequate to provide coverage for the inherent losses on outstanding loans. The provision for loan losses amounted to approximately $9.2 million, $3.6 million, and $7.9 million for the years ended December 31, 2015, 2014, and 2013, respectively.

Impacting the provision for loan losses in any accounting period are several factors including the change in outstanding loan balances, the level of charge-offs and recoveries, the changes in the amount of impaired loans, changes in the risk ratings assigned to our loans, results of regulatory examinations, credit quality comparison to peer banks, the industry at large, and, ultimately, the results of our quarterly assessment of the inherent risks of our loan portfolio including past loan loss experience.

Provision expense for the year ended December 31, 2015 has increased as compared to 2014, primarily due to increased charge-offs in our consumer portfolio, although the overall amount of the allowance declined. Provision expense for the year ended December 31, 2014 decreased as compared to 2013, primarily due to a reduction in both net charge-offs and the overall amount of the allowance for loan losses. As a result of the loans acquired from CapitalMark and Magna being recorded at fair value upon their acquisition date, these loans had a minimal impact on our provision expense for the year ended December 31, 2015.

Our allowance for loan losses is adjusted to an amount deemed appropriate to adequately cover probable losses in the loan portfolio based on our allowance for loan loss methodology.  Our allowance for loan losses as a percentage of loans decreased from 1.47% at December 31, 2014 to 1.00% at December 31, 2015, primarily attributable to improvements in the credit quality of our legacy Pinnacle Bank portfolio and as a result of our acquired loan portfolios being recorded at fair value upon acquisition, thus no allowance for loan losses is assigned to these loans as of the date of acquisition. An allowance for loan losses is recorded for purchased loans that have experienced credit deterioration subsequent to acquisition or increases in balances outstanding.  Based upon our evaluation of the loan portfolio, we believe the allowance for loan losses to be adequate to absorb our estimate of inherent losses existing in the loan portfolio at December 31, 2015.  While our policies and procedures used to estimate the allowance for loan losses, as well as the resultant provision for loan losses charged to operations, are considered adequate by management, they are necessarily approximate and imprecise.  There are factors beyond our control, such as conditions in the local and national economy, local real estate market or a particular industry or borrower which may negatively impact, materially, our asset quality and the adequacy of our allowance for loan losses and, thus, the resulting provision for loan losses.

Noninterest Income. Our noninterest income is composed of several components, some of which vary significantly between annual periods.  Service charges on deposit accounts and other noninterest income generally reflect our growth, while investment services, fees from the origination of mortgage loans, income from our equity method investment in BHG, swap fees and gains on the sale of securities will often reflect market conditions and fluctuate from period to period.

The following is our noninterest income for the years ended December 31, 2015, 2014, and 2013 (in thousands):

		Years ended December 31,								2015-2014 Percent Increase				Year ended December 31,				2014-2013 Percent Increase

The increase in service charges on deposit accounts in 2015 compared to 2014 and 2013 is primarily related to increased analysis fees due to an increase in the volume and number of commercial client checking accounts resulting mainly from the growth in such accounts due to our acquisitions of CapitalMark and Magna.

Also included in noninterest income are commissions and fees from investment services at our financial advisory unit, Pinnacle Asset Management, a division of Pinnacle Bank. At December 31, 2015, Pinnacle Asset Management was receiving commissions and fees in connection with approximately $1.78 billion in brokerage assets held with Raymond James Financial Services, Inc. compared to $1.70 billion at December 31, 2014. Insurance commissions earned by our insurance subsidiary were approximately $4.8 million during 2015 and $4.6 million during 2014. Included in insurance revenues for the year ended December 31, 2015 were approximately $412,000 of contingent income received based on 2014 sales production compared to $270,000 recorded in the same period prior year. Additionally, at December 31, 2015, our trust department was receiving fees on approximately $916 million and $675 million of managed and custodied assets, respectively, compared to approximately $765 million and $861 million at December 31, 2014.

Gains on mortgage loans sold consists of fees from the origination and sale of mortgage loans.  These mortgage fees are for loans originated in our current markets that are subsequently sold to third-party investors. Substantially all of these loan sales transfer servicing rights to the buyer. We acquired a mortgage servicing operation in conjunction with our acquisition of Magna; however, during the first quarter of 2016, we entered into a letter of intent to sell this operation. Generally, mortg age origination fees increase in lower interest rate environments and more robust housing markets and decrease in rising interest rate environments and more challenging housing markets. Mortgage origination fees will fluctuate from quarter to quarter as the rate environment changes. Gains on mortgage loans sold, net, were $7.7 million during the year ended December 31, 2015 compared to $5.6 million and $6.2 million, respectively, for the years ended December 31, 2014 and 2013.

During the year ended December 31, 2013, we recognized an other-than-temporary-impairment charge in the third quarter of 2013 of $1.4 million on approximately $22.1 million of bonds that were subsequently sold during the fourth quarter. To better manage our securities portfolio, we elected to sell these securities due to their relative underperformance compared to the market, in order to minimize small dollar investments in our portfolio and due to OTTI concerns on investment securities in certain municipalities. The net gains we recognized during the years ended December 31, 2015 and 2014 on bond sales were $552,000 and $29,000, respectively.

Income from equity-method investment is comprised of income from our 30% equity-method investment in BHG, which was made during the first quarter of 2015, and was $20.6 million for the year ended December 31, 2015. Income from this equity-method investment is recorded net of any associated expenses, including amortization expense of $1.3 million for the year ended December 31, 2015.  During the year ended December 31, 2015, Pinnacle Bank received $7.1 million in dividends from BHG, which pursuant to the equity method of accounting reduced the carrying amount of our investment in BHG. On January 19, 2016, Pinnacle Financial and Pinnacle Bank agreed to acquire an additional 19% interest in BHG. We expect this additional investment to close in early March 2016. The income associated with this equity-method investment may fluctuate from period to period.

Included in other noninterest income are interchange and other consumer fees, gains from bank-owned life insurance, swap fees earned for the facilitation of derivative transactions for our clients and other items. Interchange revenues increased as a result of increased debit and credit card transactions as compared to the comparable period in 2014. Other noninterest income included changes in the cash surrender value of bank-owned life insurance which was $2.5 million for the year ended December 31, 2015 compared to $2.4 million for the year ended December 31, 2014. The increase in earnings on these bank-owned life insurance policies resulted primarily from the additional $17.0 million in bank-owned life insurance with terms similar to our existing policies which were added upon acquisition of CapitalMark. The assets that support these policies are administered by the life insurance carriers and the income we receive (i.e., increases or decreases in the cash surrender value of the policies) on these policies is dependent upon the returns the insurance carriers are able to earn on the underlying investments that support the policies. Earnings on these policies generally are not taxable. Loan swap fees, which are also included in other noninterest income, increased by $1.9 million when compared to the year ended December 31, 2014 as a result of increased market demand for these products in the current rate environment. Also included in other noninterest income are the results from our mortgage servicing division which was acquired upon our acquisition of Magna and amounted to $1.7 million for the year ended December 31, 2015. In the first quarter of 2016, Pinnacle entered into a letter of intent to sell the servicing rights to approximately $830 million Fannie Mae mortgage loans in a transaction expected to be completed in the second quarter of 2016. Pinnacle Financial does not anticipate the sale of this servicing portfolio to have a material impact on its financial condition or its results of operations.
