(1)Our consolidated statements of income for the three and nine months ended September 30, 2016 were modified from prior period's presentation to conform to the current period's presentation, which reflects our provision for loan losses and provision for unfunded credit commitments together as our “provision for credit losses”. In prior periods, our provision for unfunded credit commitments were reported as a component of noninterest expense.
(2)Our consolidated statements of income for the three and nine months ended September 30, 2016 were modified from prior period's presentation to conform to the current period's presentation, which reflects a new line item to separately disclose net gains on equity warrant assets. In prior periods, net gains on equity warrant assets were reported as a component of gains on derivative instruments, net. We removed the line item gains on derivative instruments, net and reclassified all other gains on derivative instruments, net to other noninterest income.
(3)Included in income tax expense, net income available to common shareholders, earnings per common share-basic and earnings for common share-diluted, for the three and nine months ended September 30, 2017, are tax benefits recognized associated with the adoption of Accounting Standards Update (“ASU”) 2016-09, Improvements to Employee Share-Based Payment Accounting in the first quarter of 2017. This guidance was adopted on a prospective basis with no change to prior period amounts.

During the first quarter of 2017 we adopted ASU 2016-09, Improvements to Employee Share-Based Payment Accounting. The amendments in this ASU require that all excess tax benefits and tax deficiencies associated with share-based compensation be recognized in income tax expense or benefit in the income statement. Previously, tax effects resulting from changes in the Company's share price subsequent to grant date of share-based compensation awards were recorded through additional paid-in-capital in stockholders' equity at the time of vesting and exercise. This guidance was adopted on a prospective basis with no change to prior period amounts. See Note 1—“Basis of Presentation” of the “Notes to Interim Consolidated Financial Statements (unaudited)” under Part I, Item 1 of this report for additional details.

SVB FINANCIAL GROUP AND SUBSIDIARIES
NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
1.
Basis of Presentation
SVB Financial Group is a diversified financial services company, as well as a bank holding company and a financial holding company. SVB Financial was incorporated in the state of Delaware in March 1999. Through our various subsidiaries and divisions, we offer a variety of banking and financial products and services to support our clients of all sizes and stages throughout their life cycles. In these notes to our consolidated financial statements, when we refer to “SVB Financial Group,” “SVBFG”, the “Company,” “we,” “our,” “us” or use similar words, we mean SVB Financial Group and all of its subsidiaries collectively, including Silicon Valley Bank (the “Bank”), unless the context requires otherwise. When we refer to “SVB Financial” or the “Parent” we are referring only to the parent company, SVB Financial Group (not including subsidiaries).
The accompanying unaudited interim consolidated financial statements reflect all adjustments of a normal and recurring nature that are, in the opinion of management, necessary to fairly present our financial position, results of operations and cash flows in accordance with GAAP. Such unaudited interim consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q pursuant to the rules and regulations of the SEC. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. The results of operations for the three and nine months ended September 30, 2017March 31, 2018 are not necessarily indicative of results to be expected for any future periods. These unaudited interim consolidated financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 20162017 (“20162017 Form 10-K”).
The accompanying unaudited interim consolidated financial statements have been prepared on a consistent basis with the accounting policies described in Consolidated Financial Statements and Supplementary Data—Note 2—“Summary of Significant Accounting Policies” under Part II, Item 8 of our 20162017 Form 10-K.
The preparation of unaudited interim consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Estimates may change as new information is obtained. Significant items that are subject to such estimates include measurements of fair value, the valuation of non-marketable and other equity securities, the valuation of equity warrant assets, the adequacy of the allowance for loan losses and allowance for unfunded credit commitments, and the recognition and measurement of income tax assets and liabilities.
Principles of Consolidation and Presentation
Our consolidated financial statements include the accounts of SVB Financial Group and consolidated entities. We consolidate voting entities in which we have control through voting interests or entities through which we have a controlling financial interest in a variable interest entity (“VIE”). We determine whether we have a controlling financial interest in a VIE by determining if we have: (a) the power to direct the activities of the VIE that most significantly impact the entity’s economic performance, (b) the obligation to absorb the expected losses, or (c) the right to receive the expected returns of the entity. Generally, we have significant variable interests if our commitments to a limited partnership investment represent a significant amount of the total commitments to the entity. We also evaluate the impact of related parties on our determination of variable interests in our consolidation conclusions. We consolidate VIEs in which we are the primary beneficiary based on a controlling financial interest. If we are not the primary beneficiary of a VIE, we record our pro-rata interests or our cost basis in the VIE, as appropriate, based on other accounting guidance within GAAP.our ownership percentage.
VIEs are entities where investors lack sufficient equity at risk for the entity to finance its activities without additional subordinated financial support or equity investors, as a group, lack one of the following characteristics: (a) the power to direct the activities that most significantly impact the entity’s economic performance, (b) the obligation to absorb the expected losses of the entity, or (c) the right to receive the expected returns of the entity. We assess VIEs to determine if we are the primary beneficiary of a VIE.  A primary beneficiary is defined as a variable interest holder that has a controlling financial interest. A controlling financial interest requires both: (a) power to direct the activities that most significantly impact the VIE’s economic performance, and (b) obligation to absorb losses or receive benefits of a VIE that could potentially be significant to a VIE. Under this analysis, we also evaluate kick-out rights and other participating rights which could provide us a controlling financial interest. The primary beneficiary of a VIE is required to consolidate the VIE.
We also evaluate fees paid to managers of our limited partnership investments. We exclude those fee arrangements that are not deemed to be variable interests from the analysis of our interests in our investments in VIEs and the determination of a primary beneficiary, if any. Fee arrangements based on terms that are customary and commensurate with the services provided are deemed not to be variable interests and are, therefore, excluded.

All significant intercompany accounts and transactions with consolidated entities have been eliminated. We have not provided financial or other support during the periods presented to any VIE that we were not previously contractually required to provide.
Adoption of New Accounting Standards
In March 2016, the FASB issued a new accounting standard update (ASU 2016-09, Improvements to Employee Share-Based Payment Accounting (Topic 718)), which includes provisions intended to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. Under the ASU, an entity recognizes all excess tax benefits and tax deficiencies as income tax expense or benefit in the income statement in the period when the awards vest or are settled. The guidance also permits an entity to make an accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. We adopted this guidance on January 1, 2017 and elected to estimate the number of awards that are expected to vest which, is consistent with the previous accounting guidance. In addition, we also elected to apply the amendments related to the presentation of excess tax benefits on the statement of cash flows using the prospective transition method.
Previously, tax effects resulting from changes in the Company's share price subsequent to grant date of share-based compensation awards were recorded through additional paid-in capital in stockholders' equity at the time of vesting and exercise. The adoption of the amended accounting guidance resulted in a $1.3 million and $14.4 million reduction of income tax expense (that previously would have been reflected as additional paid-in capital), or a benefit of $0.02 and $0.27 per diluted common share, for the three and nine months ended September 30, 2017, respectively. We expect the impact of this amendment will vary period to period depending on the volatility of the Company's stock price and the timing of vesting and/or settlement of awards.
Recent Accounting Pronouncements
In May 2014, the FASB issued a new accounting standard update (ASU 2014-09, Revenue from Contracts with Customers (Topic 606)), which provides revenue recognition guidance that is intended to create greater consistency with respect to how and when revenue from contracts with customers is shown in the income statement. The guidance requires that revenue from contracts with customers be recognized when transfer of control over goods or services is passed to customers in the amount of consideration expected to be received. received. Subsequent Accounting Standard Updates have been issued clarifying the original pronouncement (ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2016-20). The new standard and amendments will be effective
On January 1, 2018, either on a full retrospective approachwe adopted the new accounting standard ASU 2014-09, Revenue from Contracts with Customers and all the related amendments ("new revenue standard", "ASC 606" or a modified retrospective approach. We plan to adopt the revenue guidance in the first quarter of 2018"ASU 2014-09") using the modified retrospective transition approachmethod applied to those contracts which arewere not completed as of January 1, 2018. Upon adoption, we will recognizeWe elected to apply the cumulative-effectpractical expedient which allows us to expense costs related to obtaining contracts as incurred because the amortization period would have been one year or less. We recognized the cumulative effect of adopting this guidanceinitially applying the new revenue standard as an adjustment to the opening balance of retained earnings. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods.
We have conductedcompleted a comprehensive scoping exercise to determine the revenue streams that are within the scope of this guidance. The scope of this guidance explicitly excludes net interest income, including interest income earned from our loan and fixed income securities portfolios, as well as certain other noninterest income earned from our lending-, investment- and derivative-related activities. Based on our contract assessments to-date,completed assessment, we havedid not identifiedidentify any material changes to the timing or the amounts of our revenue recognition. We expect minor changesrecognition, however, we identified a change in the timing of recognizing fund management fees in other noninterest income for a portion of our SVB Capital funds. Fund management fees for these certain SVB Capital funds as the fees will now be recognized at the time of distribution which typically occurs later in the life of the fund life than had been previously recognized. Based on our preliminary analysis, we expect theThe cumulative adjustment to retained earnings associated with this change to be from $7was $5.8 million, to $10 million,net of tax, with an immaterial impact to our net income on an ongoing basis.
The timing of revenue recognition may differ from the timing of cash settlements or invoicing to customers. We continuerecord a receivable when revenue is recognized prior to evaluateinvoicing, and unearned revenue when revenue is recognized subsequent to receipt of consideration.These assets and liabilities are reported on the consolidated balance sheets on a contract-by-contract basis at the end of each reporting period. During the three months ended March 31, 2018, changes in our contract assets, contract liabilities and receivables were not material. Additionally, revenues recognized during the three months ended March 31, 2018 that were included in the corresponding contract liability balance at the beginning of the period were not material.
The cumulative effect of the guidance has onchanges to our revenue and the presentation of certain costs associated with our credit card and merchant services and whether these costs are presented in noninterest expense or offset against credit card fees in noninterest income. We currently recognize payment networks costs associated with our credit card and merchant services in noninterest expense. If we determine thatconsolidated balance sheets at January 1, 2018, for the adoption of the guidance results in a change in the presentation of these costs, we estimate that this will result in approximately $10 million to $15 million of annual expenses would be netted against credit card interchange fees and reported in noninterest income instead of other noninterest expense. This change would occur on a prospective basis starting January 1, 2018 and would reduce our non-GAAP core fee income within noninterest income and also reduce noninterest expense with no impact to net income. Furthermore, we continue to evaluate the disaggregation of our significant categories ofnew revenue within the scope of this guidance and plan to expand our qualitative disclosures of our noninterest income within the Consolidated Financial Statements upon adoption in 2018.standard were as follows:

In February 2018, the FASB issued a new accounting standard update (ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (ASU "2018-02")) to address certain stranded income tax effects in accumulated other comprehensive income ("AOCI") resulting from H.R.1, known as the Tax Cuts and Jobs Act (the "TCJ Act"). ASU 2018-02 changed current accounting whereby an entity may elect to reclassify the stranded tax effect from AOCI to retained earnings in each period in which the effect of the change in the U.S. federal corporate income tax rate in the TCJ Act (or portion thereof) is recorded. ASU 2018-02 is effective for periods beginning after December 15, 2018 and early adoption is permitted. We have elected to early adopt ASU 2018-02 and reclassified approximately $0.3 millionfrom accumulated other comprehensive income to retained earnings within our consolidated statements of stockholders' equity for the three months ended March 31, 2018.
On January 1, 2018, we adopted the new accounting standard update ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (Topic 825)), which addresses certain aspects of recognition, measurement, presentation and disclosure of financial instruments. This guidance requires equity investments (except those accounted for under the equity method of accounting) to be measured at fair value with changes in fair value recognized in net income. The adoption ofWe adopted this guidance using the new standard will result in the elimination of costmodified retrospective method accounting for equity investments and will impact our nonmarketable

and other equity securities that are currently carried at cost. This guidance will be effective on January 1, 2018, and our equity investments measuredcarried at cost will be measuredwith readily determinable fair values were re-measured at fair value and the difference between cost and fair value at adoption date will bewas recorded as a cumulative-effect adjustment to opening retained earnings as of the fiscal year of adoption for our cost method venture capital and private equity fund investments with readily determinable fair values.January 1, 2018. The actual adjustment to opening retained earnings will depend upon the fair valuefor these investments was $74.6 million, net of our investments at the adoption date but based on September 30, 2017 and historical values, we expect the transition adjustment to increase capital between $110 million and $120 million on a pre-tax basis. Anytax, with subsequent changes in the fair value will beof these equity securities recorded as unrealized gains or losses in our consolidated statements of income. Additionally, in accordance with this guidance, net unrealized gains of $29.2 million, net of tax, included in accumulated other comprehensive income on January 1, 2018, related to our previously reported available-for-sale equity securities, were reclassified as an adjustment to retained earnings. Subsequent changes in the fair value of these equity securities were recorded as unrealized gains or losses in our consolidated statements of income. Furthermore, for purposes of disclosing the fair value of loans carried at amortized cost, we are evaluating our valuation methods to determine the necessary changesmethodology was updated to conform to an “exit price” concept as required by the standard update. Accordingly,update, resulting in an immaterial change in the fair valuevalue.
In August 2016, the FASB issued a new accounting standard update (ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments), which clarifies the guidance on eight specific cash flow issues. We adopted the new accounting standard, specifically as it relates to distributions from our equity method investments, on January 1, 2018. We elected to adopt the nature of distribution approach and applied the guidance retrospectively. The new guidance had an immaterial impact on the presentation between investing and operating activities within our statements of cash flows related to distributions and net gains from our nonmarketable and other securities portfolio.

In November 2016, the FASB issued a new accounting standard update (ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash), which requires that a statement of cash flows explains the change during the period in the total cash, cash equivalents, and amounts disclosed forgenerally described as restricted cash or restricted cash equivalents.  Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning of period and end of period total amounts shown on the statement of cash flows.  Previous to the update, there had been some diversity in practice.  Given that we had already classified restricted cash such loans may change upon adoption.as cash reserves at the Federal Reserve as part of cash and cash equivalents on the cash flow statement, the update had no impact on how we were already reporting and presenting our statement of cash flows.
Recent Accounting Pronouncements
In February 2016, the FASB issued a new accounting standard update (ASU 2016-02, Leases (Topic 842)), which will require for all operating leases the recognition of a right-of-use asset and a corresponding lease liability, in the statement of financial position. The lease cost will be allocated over the lease term on a straight-line basis. This guidance will be effective on January 1, 2019, on a modified retrospective basis, with early adoption permitted. We plan to adopt the lease accounting guidance in the first quarter of 2019 and are currently evaluating the impact this guidance will have on our consolidated financial statements by reviewing our existing lease contracts and service contracts that may include embedded leases. WeWhile we are continuing to assess potential impacts of the standard, we currently expect to recognize right-of-use assets and related lease liabilities associated predominantly with noncancelable operating leases, as included in the table of minimum future payments, in the amount of $217$226 million as disclosed in Note 1819 of our 20162017 Form 10-K.
In June 2016, the FASB issued a new accounting standard update (ASU 2016-13, Financial Instruments- Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments), which amends the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses over the life of the loan and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. This guidance will be effective January 1, 2020, on a modified retrospective approach, with early adoption permitted, but not before January 1, 2019. We currently have a working project team in place and subject matter experts to assist with our review of key interpretive issues and assist in the assessment of our existing credit loss forecasting models and processes against the new guidance to determine what modifications may be required. We are currently evaluating the impact this guidance will have on our financial position, results of operation and stockholders’ equity.
In August 2016, the FASB issued a new accounting standard update (ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments), which clarifies the guidance on eight specific cash flow issues. This guidance will be effective January 1, 2018 on a full retrospective approach, with early adoption permitted. Our preliminary evaluation has resulted in the expectation that this guidance will primarily impact the presentation between investing and operating activities within our statements of cash flows related to distributions and net gains from our nonmarketable and other securities portfolio. We are continuing to evaluate any further impact of this guidance to the presentation of our operating, investing and financing activities within our statements of cash flows.
Reclassifications
Certain prior period amounts, primarily related to the changes to our income statement presentationadoption of net gains on derivative instruments and provision for unfunded credit commitmentsnew accounting guidance, have been reclassified to conform to current period presentations.

EPS
Basic EPS is the amount of earnings available to each share of common stock outstanding during the reporting period. Diluted EPS is the amount of earnings available to each share of common stock outstanding during the reporting period adjusted to include the effect of potentially dilutive common shares. Potentially dilutive common shares include incremental shares issuable for stock options and restricted stock units outstanding under our 2006 Equity Incentive Plan and our ESPP. Potentially dilutive common shares are excluded from the computation of dilutive EPS in periods in which the effect would be antidilutive. The following is a reconciliation of basic EPS to diluted EPS for the three and nine months ended September 30, 2017March 31, 2018 and 20162017:

(1)Included in our unconsolidated non-marketable and other equity securities portfolio at September 30, 2017March 31, 2018 and December 31, 20162017 are investments in qualified affordable housing projects of $148.0$225.8 million and $112.4$174.2 million, respectively, and related other liabilities consisting of unfunded credit commitments of $91.0$137.8 million and $58.1$100.9 million, respectively.

Non-marketable and other equity securities
Our non-marketable and other equity securities portfolio primarily represents investments in venture capital and private equity funds, SPD Silicon Valley Bank Co., Ltd. (the Bank's joint venture bank in China (“SPD-SVB”)), debt funds, private and public portfolio companies and investments in qualified affordable housing projects. A majority of these investments are through thirdthird- party funds held by SVB Financial in which we do not have controlling or significant variable interests. These investments represent our unconsolidated VIEs in the table above. Our non-marketable and other equity securities portfolio also includes investments from SVB Capital. SVB Capital is the funds management business of SVB Financial Group, which focuses primarily on venture capital investments. The SVB Capital family of funds is comprised of direct venture funds that invest in companies and funds of funds that invest in other venture capital funds. We have a controlling and significant variable interest in four of these SVB Capital funds and consolidate these funds for financial reporting purposes.
All investments are generally nonredeemable and distributions are expected to be received through the liquidation of the underlying investments throughout the life of the investment fund. Investments may only be sold or transferred subject to the notice and approval provisions of the underlying investment agreement. Subject to applicable regulatory requirements, including the Volcker Rule, we also make commitments to invest in venture capital and private equity funds. For additional details, see Note 12—13—“Off-Balance Sheet Arrangements, Guarantees and Other Commitments” of the “Notes to Interim Consolidated Financial Statements (unaudited)” under Part I, Item 1 of this report.
The Bank also has variable interests in low income housing tax credit funds, in connection with fulfilling its responsibilities under the Community Reinvestment Act (“CRA”), that are designed to generate a return primarily through the realization of federal tax credits. These investments are typically limited partnerships in which the general partner, other than the Bank, holds the power over significant activities of the VIE; therefore, these investments are not consolidated. For additional information on our investments in qualified affordable housing projects see Note 6—“Investment Securities" of the “Notes to Interim Consolidated Financial Statements (unaudited)” under Part I, Item 1 of this report.

As of September 30, 2017,March 31, 2018, our exposure to loss with respect to the consolidated VIEs is limited to our net assets of $197.4$205.0 million and our exposure to loss for our unconsolidated VIEs is equal to our investment in these assets of $323.3$501.8 million.

As of September 30, 2017March 31, 2018, we identified a total of 202281 investments that were in unrealized loss positions, of which 6352 investments totaling $477.7 million1.1 billion with unrealized losses of $9.78.4 million have been in an impaired position for a period of time greater than 12 months. As of September 30, 2017March 31, 2018, we do not intend to sell any of our impaired securities prior to recovery of our adjusted cost basis, and it is more likely than not that we will not be required to sell any of our securities prior to recovery of our adjusted cost basis. Based on our analysis as of September 30, 2017March 31, 2018, we deem all impairments to be temporary, and therefore changes in value for our temporarily impaired securities as of the same date are included in other comprehensive income. Market valuations and impairment analyses on assets in the available-for-sale securities portfolio are reviewed and monitored on a quarterly basis.

As of December 31, 20162017, we identified a total of 174268 investments that were in unrealized loss positions, of which 2046 investments totaling $233.5713.3 million with unrealized losses of $6.75.8 million have been in an impaired position for a period of time greater than 12 months.

The following table summarizes thefixed income securities, carried at fair value, classified as available-for-sale as of September 30, 2017March 31, 2018 by the remaining contractual principal maturities. For U.S. Treasury securities and U.S. agency debentures, the expected maturity is the actual contractual maturity of the notes. Expected maturities for mortgage-backed securities may differ significantly from their contractual maturities because mortgage borrowers have the right to prepay outstanding loan obligations with or without penalties. Mortgage-backed securities classified as available-for-sale typically have original contractual maturities from 10 to 30 years whereas expected average lives of these securities tend to be significantly shorter and vary based upon structure and prepayments in lower interest rate environments.

Expected maturities for mortgage-backed securities may differ significantly from their contractual maturities because mortgage borrowers have the right to prepay outstanding loan obligations with or without penalties. Mortgage-backed securities classified as held-to-maturity typically have original contractual maturities from 10 to 30 years whereas expected average lives of these securities tend to be significantly shorter and vary based upon structure and prepayments in lower interest rate environments.

Effective January 1, 2018 we adopted ASU 2016-01 Recognition and Measurement of Financial Assets and Financial Liabilities which eliminated the concept of cost method accounting. On a prospective basis we will carry our unconsolidated venture capital and private equity fund investments at fair value accounting):based on the fund investments' net asset values per share as obtained from the general partners of the investments. We adjust the net asset value per share for differences between our measurement date and the date of the fund investment’s net asset value by using the most recently available financial information from the investee general partner, for example December 31st, for our March 31st consolidated financial statements, adjusted for any contributions paid, distributions received from the investment, and significant fund transactions or market events during the reporting period. We recorded a cumulative adjustment to opening retained earnings on January 1, 2018 for the difference between fair value and cost for these fund investments. The estimated fair value and carrying value of these venture capital and private equity fund investments was $205.7 million as of March 31, 2018. As of December 31, 2017, these investments were carried at cost and had a carrying value of $98.5 million.

(3)Effective January 1, 2018 we adopted ASU 2016-01 Recognition and Measurement of Financial Assets and Financial Liabilities which eliminated the concept of cost method accounting. On a prospective basis we will report our other investments in the line item "Other investments without a readily determinable fair value". These investments include direct equity investments in private companies. The carrying value is based on the price at which the investment was acquired plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments. We consider a range of factors when adjusting the fair value of these investments, including, but not limited to, the term and nature of the investment, local market conditions, values for comparable securities, current and projected operating performance, exit strategies, financing transactions subsequent to the acquisition of the investment and a discount for certain investments that have lock-up restrictions or other features that indicate a discount to fair value is warranted. The following table shows the changes to the carrying amount of other investments without a readily determinable fair value for the three months ended March 31, 2018:

(4)Investments classified as other equity securities (fair value accounting) represent shares held in public companies as a result of exercising public equity warrant assets and direct public equity investments in public companies held by our consolidated funds. Effective January 1, 2018 we adopted ASU 2016-01 Recognition and Measurement of Financial Assets and Financial Liabilities which requires equity securities to be measured at fair value with changes in the fair value recognized through net income. Prior to January 1, 2018 we reported equity securities in public companies that we held as a result of exercising public equity warrant assets in available-for-sale securities. On a prospective basis, these equity securities will be reported in non-marketable and other equity securities.

7.Loans, Allowance for Loan Losses and Allowance for Unfunded Credit Commitments
We serve a variety of commercial clients in the technology, life science/healthcare, private equity/venture capital and premium wine industries. Our technology clients generally tend to be in the industries of hardware (semiconductors, communications, data, storage, and electronics), software/internet (such as infrastructure software, applications, software services, digital content and advertising technology), and energy and resource innovation (“ERI”). Because of the diverse nature of ERI products and services, for our loan-related reporting purposes, ERI-related loans are reported under our hardware, software/internet, life science/healthcare and other commercial loan categories, as applicable. Our life science/healthcare clients primarily tend to be in the industries of biotechnology, medical devices, healthcare information technology and healthcare services. Loans made to private equity/venture capital firm clients typically enable them to fund investments prior to their receipt

of funds from capital calls. Loans to the premium wine industry focus on vineyards and wineries that produce grapes and wines of high quality.
In addition to commercial loans, we make consumer loans through SVB Private Bank and provide real estate secured loans to eligible employees through our EHOP. Our private banking clients are primarily private equity/venture capital professionals and executive leaders in the innovation companies they support. These products and services include real estate secured home equity lines of credit, which may be used to finance real estate investments and loans used to purchase, renovate or refinance personal residences. These products and services also include restricted stock purchase loans and capital call lines of credit.
We also provide community development loans made as part of our responsibilities under the Community Reinvestment Act. These loans are included within “Construction loans” below and are primarily secured by real estate.

Credit Quality Indicators
For each individual client, we establish an internal credit risk rating for that loan, which is used for assessing and monitoring credit risk as well as performance of the loan and the overall portfolio. Our internal credit risk ratings are also used to summarize the risk of loss due to failure by an individual borrower to repay the loan. For our internal credit risk ratings, each individual loan is given a risk rating of 1 through 10. Loans risk-rated 1 through 4 are performing loans and translate to an internal rating of “Pass”, with loans risk-rated 1 being cash secured. Loans risk-rated 5 through 7 are performing loans, however, we consider them as demonstrating higher risk, which requires more frequent review of the individual exposures; these translate to an internal rating of “Performing (Criticized)”. When a significant payment delay occurs onfull repayment of a criticized loan has been deemed improbable under the original contractual terms but full repayment remains probable overall, the loan is impaired. The loan is also considered for nonaccrual status if full repayment is determined to be improbable.a “Performing Impaired (Criticized)” loan. All of our nonaccrual loans are risk-rated 8 or 9 and are classified under the nonperforming impaired category. (For further description of nonaccrual loans, refer to Note 2—“Summary of Significant Accounting Policies” under Part II, Item 8 of our 20162017 Form 10-K). Loans rated 10 are charged-off and are not included as part of our loan portfolio balance. We review our credit quality indicators for performance and appropriateness of risk ratings as part of our evaluation process for our allowance for loan losses.

During the three and nine months ended September 30, 2017March 31, 2018 all new TDRs of $11.3$3.9 million and $26.6 million, respectively, were modified through payment deferrals granted to our clients.
During the three months ended September 30, 2016, $12.0 million ofMarch 31, 2017, all new TDRs of $6.3 million were modified through payment deferrals granted to our clients and $0.1 million were modified through partial forgiveness of principal. During the nine months ended September 30, 2016, $17.6 million of new TDRs were modified through payment deferrals granted to our clients and $0.3 million were modified through partial forgiveness of principal.clients.
The related allowance for loan losses for the majority of our TDRs is determined on an individual basis by comparing the carrying value of the loan to the present value of the estimated future cash flows, discounted at the pre-modification contractual interest rate. For certain TDRs, the related allowance for loan losses is determined based on the fair value of the collateral if the loan is collateral dependent.

The following table summarizes the recorded investment in loans modified in TDRs within the previous 12 months that subsequently defaulted during the three and nine months ended September 30, 2017March 31, 2018 and September 30, 2016.2017:

Charge-offs and defaults on previously restructured loans are evaluated to determine the impact to the allowance for loan losses, if any. The evaluation of these defaults may impact the assumptions used in calculating the reserve on other TDRs and impaired loans as well as management’s overall outlook of macroeconomic factors that affect the reserve on the loan portfolio as a whole. After evaluating the charge-offs and defaults experienced on our TDRs we determined that no change to our reserving methodology was necessary to determine the allowance for loan losses as of September 30, 2017.March 31, 2018.

Our 6.05% Subordinated Notes were repaid on June 1, 2017 and therefore, the interest rate swap agreement related to this issuance was terminated upon repayment of the 6.05% Subordinated Notes. At December 31, 2016, included in the carrying value of our 6.05% Subordinated Notes were $0.8 million related to hedge accounting associated with the notes.
Interest expense related to short-term borrowings and long-term debt was $9.0$0.4 million and $27.2$8.0 million for the three and nine months ended September 30, 2017March 31, 2018, respectively, and $9.7 million and $28.2 million for the three and nine months ended September 30, 2016, respectively. Interest expense is net of the hedge accounting impact from our interest rate swap agreement related to our 6.05% Subordinated Notes through June 1, 2017. The weighted average interest rate associated with our short-term borrowings was 1.061.82 percent as of September 30, 2017March 31, 2018 and 0.591.39 percent as of December 31, 2016.2017.

Available Lines of Credit
We have certain facilities in place to enable us to access short-term borrowings on a secured (using high-quality fixed incomeloans and AFS securities as collateral) and an unsecured basis. These include repurchase agreements and uncommitted federal funds lines with various financial institutions. As of September 30, 2017March 31, 2018, we did not have anyhad borrowings of $395.0 million outstanding against our uncommitted federal funds lines. We also pledge securities to the FHLB of San Francisco and the discount window at the Federal Reserve Bank.FRB. The fair value of collateral pledged to the FHLB of San Francisco (comprised primarily of loans and U.S. Treasury securities) at September 30, 2017March 31, 2018 totaled $1.93.8 billion, all of which $3.1 billion was unused and available to support additional borrowings. The fair value of collateral pledged at the discount window of the Federal Reserve BankFRB (comprised primarily of U.S. Treasury securities and U.S. agency debentures) at September 30, 2017March 31, 2018 totaled $0.71.0 billion, all of which was unused and available to support additional borrowings.

9.Derivative Financial Instruments
We primarily use derivative financial instruments to manage interest rate risk, currency exchange rate risk and to assist customers with their risk management objectives.objectives, which may include currency exchange rate risks and interest rate risks. Also, in connection with negotiating credit facilities and certain other services, we often obtain equity warrant assets giving us the right to acquire stock in private, venture-backed companies in the technology and life science/healthcare industries.
Interest Rate Risk
Interest rate risk is our primary market risk and can result from timing and volume differences in the repricing of our interest rate sensitive assets and liabilities and changes in market interest rates. To manage interest rate risk for our 6.05% Subordinated Notes, we entered into a fixed-for-floating interest rate swap agreement at the time of debt issuance based upon LIBOR with matched-terms. The net cash benefit associated with our interest rate swap is recorded as a reduction in “Interest expense—Borrowings,” a component of net interest income. The fair value of our interest rate swaps is calculated using a discounted cash flow method and adjusted for credit valuation associated with counterparty risk. Changes in fair value of the interest rate swaps are reflected in either other assets (for swaps in an asset position) or other liabilities (for swaps in a liability position). On June 1, 2017, our interest rate swap was terminated upon repayment of the 6.05% Subordinated Notes.
Currency Exchange Risk
We enter into foreign exchange forward contracts to economically reduce our foreign exchange exposure risk associated with the net difference between foreign currency denominated assets and liabilities. We do not designate any foreign exchange forward contracts as derivative instruments that qualify for hedge accounting. Gains or losses from changes in currency rates on foreign currency denominated instruments are recorded in the line item “Other”“other” as part of noninterest income, a component of consolidated net income. We may experience ineffectiveness in the economic hedging relationship, because the instruments are revalued based upon changes in the currency’s spot rate on the principal value, while the forwards are revalued on a discounted cash flow basis. We record forward agreements in gain positions in other assets and loss positions in other liabilities, while net changes in fair value are recorded in the line item “Other”“other” as part of noninterest income, a component of consolidated net income.
Other Derivative Instruments
Also included in our derivative instruments are equity warrant assets and client forward and option contracts, and client interest rate contracts. For further description of these other derivative instruments, refer to Note 2-“Summary of Significant Accounting Policies" under Part II, Item 8 of our 20162017 Form 10-K.
Counterparty Credit Risk
We are exposed to credit risk if counterparties to our derivative contracts do not perform as expected. We mitigate counterparty credit risk through credit approvals, limits, monitoring procedures and obtaining collateral, as appropriate. With respect to measuring counterparty credit risk for derivative instruments, we measure the fair value of a group of financial assets and financial liabilities on a net risk basis by counterparty portfolio.

Derivative assets and liabilities are included in relation to market value exposures of derivative contracts in our favor is recorded as a component of “short-term borrowings”"other interest receivables and other assets" and "other liabilities", respectively, on our consolidated balance sheets.
(2)Net exposure
The amount reported for contractsMarch 31, 2018 reflects rule changes implemented by two central clearing houses that allow entities to elect to treat derivative assets, liabilities and the related variation margin as settlement of the related derivative fair values for legal and accounting purposes, as opposed to presenting gross derivative assets and liabilities. As a result, client interest rate derivatives at March 31, 2018, reflect reductions of approximately $8.6 million of derivative assets that previously would have been reported on a gross basis and approximately $433.6 million in a gain position reflects the replacement cost in the event of nonperformance by all such counterparties. The credit ratings of our institutional counterparties as of September 30, 2017 remain at investment grade or higher and there were no material changes in their credit ratings during the three and nine months ended September 30, 2017.related notional amounts for these derivative assets cleared through central clearing houses.

Gains on investment securities, net
Net gains on investment securities include both gains and losses from our non-marketable and other equity securities, including carried interest, as well as gains and losses from sales of our available-for-sale securities portfolio, when applicable.
Our non-marketable and other equity securities portfolio primarily represents investments in venture capital and private equity funds, our China Joint Venture, debt funds, private and public portfolio companies and investments in qualified affordable housing projects. We experience variability in the performance of our non-marketable and other equity securities from period to period, which results in net gains or losses on investment securities (both realized and unrealized). This variability is due to a number of factors, including unrealized changes in the values of our investments, changes in the amount of realized gains from distributions, changes in liquidity events and general economic and market conditions. Unrealized gains from non-marketable and other equity securities for any single period are typically driven by valuation changes, and are therefore subject to potential increases or decreases in future periods. Such variability may lead to volatility in the gains or losses from investment securities. As such, our results for a particular period are not necessarily indicative of our expected performance in a future period.
The extent to which any unrealized gains or losses will become realized is subject to a variety of factors, including, among other things, the expiration of certain sales restrictions to which these equity securities may be subject to (i.e. lock-up agreements), changes in prevailing market prices, market conditions, the actual sales or distributions of securities, the timing of such actual sales or distributions, which, to the extent such securities are managed by our managed funds, are subject to our funds' separate discretionary sales/distributions and governance processes.
Carried interest is comprised of preferential allocations of profits recognizable when the return on assets of our individual managed fund of funds and direct venture funds exceeds certain performance targets and is payable to us, as the general partners of the managed funds. The carried interest we earn is often shared with employees, who are also members of the general partner entities. We record carried interest on a quarterly basis by measuring fund performance to date versus the performance target.  For our unconsolidated managed funds, carried interest is recorded as gains on investment securities, net. For our consolidated managed funds, it is recorded as a component of net income attributable to noncontrolling interests.  Carried interest allocated to others is recorded as a component of net income attributable to noncontrolling interests. Any carried interest paid to us (or our employees) may be subject to reversal to the extent fund performance declines to a level where inception to date carried interest is lower than actual payments made by the funds. The limited partnership agreements for our funds provide that carried interest is generally not paid to the general partners until the funds have provided a full return of contributed capital to the limited partners. Accrued, but unpaid carried interest may be subject to reversal to the extent that the fund performance declines to a level where inception-to-date carried interest is less than prior amounts recognized. Carried interest income is accounted for under an ownership model based on ASC 323 — Equity Method of Accounting and ASC 810 — Consolidation.
Our available-for-sale securities portfolio is a fixed income investment portfolio that is managed with the objective of earning an appropriate portfolio yield over the long-term while maintaining sufficient liquidity and credit diversification as well as addressing our asset/liability management objectives. These sales are conducted pursuant to the guidelines of our investment policy related to the management of our liquidity position and interest rate risk. Though infrequent, sales of debt securities in our AFS securities portfolio may result in net gains or losses and are also conducted pursuant to the guidelines of our investment policy.
Gains on investment securities are outside of the scope of the new revenue standard as it explicitly excludes noninterest income earned from our investment-related activities. A summary of gains and losses on investment securities for the three months ended March 31, 2018 and 2017, is as follows:

Gains on equity warrant assets, net
In connection with negotiating credit facilities and certain other services, we often obtain rights to acquire stock in the form of equity warrant assets in primarily private, venture-backed companies in the technology and life science/healthcare industries. Any changes in fair value from the grant date fair value of equity warrant assets will be recognized as increases or decreases to other assets on our balance sheet and as net gains or losses on equity warrant assets, in noninterest income, a component of consolidated net income. Gains on equity warrant assets are recognized outside of the scope of the new revenue standard as it explicitly excludes noninterest income earned from our derivative-related activities. A summary of net gains on equity warrant assets for the three months ended March 31, 2018 and 2017, is as follows:

Foreign exchange fees
Foreign exchange fees represent the income differential between purchases and sales of foreign currency on behalf of our clients, primarily from spot contracts. Foreign exchange spot contract fees are recognized upon the completion of the single performance obligation, the execution of a spot trade in exchange for a fee. In line with customary business practice, the legal right transfers to the client upon execution of a foreign exchange contract on the trade date, and as such, we currently recognize our fees based on the trade date and are typically settled within two business days.
Forward contract and option premium fees are recognized outside of the scope of the new revenue standard as it explicitly excludes noninterest income earned from our derivative-related activities. A summary of foreign exchange fee income by instrument type for the three months ended March 31, 2018 and 2017, is as follows:

Credit card fees
Credit card fees include interchange income from credit and debit cards and fees earned from processing transactions for merchants. Interchange income is earned after satisfying our performance obligation of providing nightly settlement services to a payment network. Costs related to rewards programs are recorded when the rewards are earned by the customer and presented as a reduction to interchange fee income. Rewards programs continue to be accounted for under ASC 310 - Receivables. Our performance obligations for merchant service fees are to transmit data and funds between the merchant and the payment network. Credit card interchange and merchant service fees are earned daily upon completion of transaction settlement services.
Annual card service fees are recognized on a straight-line basis over a 12-month period and continue to be accounted for under ASC 310 - Receivables.

Payment and cash management products and services include wire transfer and automated clearing house payment services to enable clients to transfer funds more quickly, as well as business bill pay, business credit and debit cards, account analysis, and disbursement services. Deposit service charges are recognized over the period in which the related performance obligation is provided, generally on a monthly basis.
Client investment fees
Client investment fees include fees earned from discretionary investment management services for substantially all clients, managing clients’ portfolios based on their investment policies, strategies and objectives and receives investment advisory fees. Revenue is recognized on a monthly basis upon completion of our performance obligation and consideration is typically received in the subsequent month. Included in our sweep money market fees are Rule 12(b)-1 fees, revenue sharing and from customer transactional based fees. Rule 12(b)-1 fees and revenue sharing are recognized as earned based on client funds that are invested in the period, typically monthly. Transactional based fees are earned and recognized on fixed income securities when the transaction is executed on the clients' behalf. Amounts paid to third-party service providers are predominantly expensed, such that client investment fees are recorded gross of payments made to third parties.

Fees generated from letters of credit and standby letters of credit are deferred as a component of other liabilities and recognized in noninterest income over the commitment period using the straight-line method, based on the likelihood that the commitment being drawn down will be remote. Letters of credit and standby letters of credit fees are recognized outside of the scope of the new revenue standard as it explicitly excludes noninterest income earned from our lending-related activities.
Other
Other noninterest income primarily includes income from fund management fees and service revenue. Fund management fees are comprised of fees charged directly to our managed funds of funds and direct venture funds. Fund management fees are based upon the contractual terms of the limited partnership agreements and are generally recognized as earned over the specified contract period, which is generally equal to the life of the individual fund. Fund management fees are calculated as a percentage of committed capital and collected in advance and are received quarterly. Fund management fees for certain of our limited partnership agreements are calculated as a percentage of distributions made by the funds and revenue is recorded only at the time of a distribution event. As distribution events are not predetermined for these certain funds, management fees are considered variable and constrained under the new revenue standard.
Other noninterest income primarily consists of dividend income on FHLB/FRB stock, correspondent bank rebate income, incentive fees related to carried interest and other fee income. We recognize revenue when our performance obligations are met and record revenues on a daily/monthly basis, quarterly, semi-annually or annual basis. For event driven revenue sources, we recognize revenue when: (i) persuasive evidence of an arrangement exists, (ii) we have performed the service, provided we have no other remaining obligations to the customer, (iii) the fee is fixed or determinable and (iv) collectability is probable.

11.12.Segment Reporting
We have three reportable segments for management reporting purposes: Global Commercial Bank, SVB Private Bank and SVB Capital. The results of our operating segments are based on our internal management reporting process.
Our Global Commercial Bank and SVB Private Bank segments' primary source of revenue is from net interest income, which is primarily the difference between interest earned on loans, net of funds transfer pricing (“FTP”), and interest paid on deposits, net of FTP. Accordingly, these segments are reported using net interest income, net of FTP. FTP is an internal measurement framework designed to assess the financial impact of a financial institution’s sources and uses of funds. It is the mechanism by which a funding credit is given for deposits raised, and a funding charge is made for loans funded. FTP is calculated at an instrument level based on account characteristics.
We also evaluate performance based on provision for credit losses, noninterest income and noninterest expense, which are presented as components of segment operating profit or loss. In calculating each operating segment’s noninterest expense, we consider the direct costs incurred by the operating segment as well as certain allocated direct costs. As part of this review, we allocate certain corporate overhead costs to a corporate account. We do not allocate income taxes or the provision for

unfunded credit commitments (included in provision for credit losses) to our segments. Additionally, our management reporting model is predicated on average asset balances; therefore, period-end asset balances are not presented for segment reporting purposes. Changes in an individual client’s primary relationship designation have resulted, and in the future may result, in the inclusion of certain clients in different segments in different periods.

Unlike financial reporting, which benefits from the comprehensive structure provided by GAAP, our internal management reporting process is highly subjective, as there is no comprehensive, authoritative guidance for management reporting. Our management reporting process measures the performance of our operating segments based on our internal operating structure, which is subject to change from time to time, and is not necessarily comparable with similar information for other financial services companies.
For reporting purposes, SVB Financial Group has three operating segments for which we report our financial information:
Global Commercial Bank is comprised of results from the following:
Our Commercial Bank products and services are provided by the Bank and its subsidiaries to commercial clients in the technology, life science/healthcare and private equity/venture capital industries. The Bank provides solutions to the financial needs of commercial clients, through credit, global treasury management, foreign exchange, global trade finance, and other services. It serves clients within the United States, as well as non-U.S. clients in key international innovation markets. In addition, the Bank and its subsidiaries offer a variety of investment services and solutions to its clients that enable them to effectively manage their assets. 
Our Private Equity Division provides banking products and services primarily to our private equity and venture capital clients.
Our Wine practice provides banking products and services to our premium wine industry clients, including vineyard development loans. 
SVB Analytics previously provided equity valuation services and currently provides research for investors and companies in the global innovation economy. In September 2017, SVB Analytics sold its equity valuation services business.
Debt Fund Investments is comprised of our investments in certain debt funds in which we are a strategic investor.
SVB Private Bank is the private banking division of the Bank, which provides a range of personal financial solutions for consumers. Our clients are primarily private equity/venture capital professionals and executive leaders of the innovation companies they support. We offer a customized suite of private banking services, including mortgages, home equity lines of credit, restricted stock purchase loans, capital call lines of credit and other secured and unsecured lending, as well as cash and wealth management services. 
SVB Capital is the funds management business of SVBFG, which focuses primarily on venture capital investments. SVB Capital manages funds (primarily venture capital funds) on behalf of third partythird-party limited partners and, on a more limited basis, SVB Financial Group. The SVB Capital family of funds is comprised of direct venture funds that invest in companies and funds of funds that invest in other venture capital funds. SVB Capital generates income for the Company primarily from investment returns (including carried interest allocations) and management fees.

The summary financial results of our operating segments are presented along with a reconciliation to our consolidated interim results.

(1)Global Commercial Bank’s and SVB Capital’s components of net interest income, noninterest income, noninterest expense and total average assets are shown net of noncontrolling interests for all periods presented. Noncontrolling interest is included within “Other Items”.
(2)The “Other Items” column reflects the adjustments necessary to reconcile the results of the operating segments to the consolidated financial statements prepared in conformity with GAAP. Net interest income consists primarily of interest earned from our fixed income investment portfolio, net of FTP. Noninterest income consists primarily of gains on equity warrant assets and gains or losses on the sale of fixed income securities.investments and equity securities from exercised warrant assets. Noninterest expense consists primarily of expenses associated with corporate support functions such as finance, human resources, marketing, legal and other expenses.
(3)
The Global Commercial Bank segment includes direct depreciation and amortization of $5.95.5 million and $6.46.1 million for the three months ended September 30, 2017March 31, 2018 and 2016, respectively, and $19.1 million and $18.3 million for the nine months endedSeptember 30, 2017 and 2016, respectively.

(4)The internal reporting model used by management to assess segment performance does not calculate income tax expense by segment. Our effective tax rate is a reasonable approximation of the segment rates.
(5)Total average assets equal the greater of total average assets or the sum of total average liabilities and total average stockholders’ equity for each segment to reconcile the results to the consolidated financial statements prepared in conformity with GAAP.
12.13.Off-Balance Sheet Arrangements, Guarantees and Other Commitments
In the normal course of business, we use financial instruments with off-balance sheet risk to meet the financing needs of our customers. These financial instruments include commitments to extend credit, commercial and standby letters of credit and commitments to invest in venture capital and private equity fund investments. These instruments involve, to varying degrees, elements of credit risk. Credit risk is defined as the possibility of sustaining a loss because other parties to the financial instrument fail to perform in accordance with the terms of the contract.

Commitments to Invest in Venture Capital and Private Equity Funds
Subject to applicable regulatory requirements, including the Volcker Rule, we make commitments to invest in venture capital and private equity funds, which generally makes investments in privately-held companies. Commitments to invest in these funds are generally made for a 10-year period from the inception of the fund. Although the limited partnership agreements governing these investments typically do not restrict the general partners from calling 100% of committed capital in one year, it is customary for these funds to call most of the capital commitments over 5 to 7 years, and in certain cases, the funds may not call 100% of committed capital. The actual timing of future cash requirements to fund these commitments is generally dependent upon the investment cycle, overall market conditions, and the nature and type of industry in which the privately held companies operate. The following table details our total capital commitments, unfunded capital commitments, and our ownership percentage in each fund at September 30, 2017March 31, 2018:

13.14.Income Taxes
We are subject to income tax in the U.S. federal jurisdiction and various state and foreign jurisdictions and have identified our federal tax return and California tax returns as major tax filings. Our U.S. federal tax returns for 2014 and subsequent tax years remain open to full examination. Our California tax returns for 2013 and subsequent tax years remain open to full examination.

At September 30, 2017,March 31, 2018, our unrecognized tax benefit was $6.3$12.8 million, the recognition of which would reduce our income tax expense by $3.8$9.9 million. We do not expect that our unrecognized tax benefit will materially change in the next 12 months.


We recognize interest and penalties related to income tax matters as part of income before income taxes. Interest and penalties were not material for the three and nine months ended September 30, 2017.March 31, 2018.
14.15.Fair Value of Financial Instruments
Fair Value Measurements
Our available-for-sale securities, derivative instruments and certain non-marketable and other equity securities are financial instruments recorded at fair value on a recurring basis. We make estimates regarding valuation of assets and liabilities measured at fair value in preparing our interim consolidated financial statements.
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (the “exit price”) in an orderly transaction between market participants at the measurement date. There is a three-level hierarchy for disclosure of assets and liabilities recorded at fair value. The classification of assets and liabilities within the hierarchy is based on whether the inputs to the valuation methodology used for measurement are observable or unobservable and the significance of those inputs in the fair value measurement. Observable inputs reflect market-derived or market-based information obtained from independent sources, while unobservable inputs reflect our estimates about market data and views of market participants. The three levels for measuring fair value are based on the reliability of inputs and are as follows:
Level 1
Fair value measurements based on quoted prices in active markets for identical assets or liabilities that we have the ability to access. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these instruments does not entail a significant degree of judgment. Assets utilizing Level 1 inputs include U.S. Treasury securities, exchange-traded equity securities and certain marketable securities accounted for under fair value accounting.
Level 2
Fair value measurements based on quoted prices in markets that are not active or for which all significant inputs are observable, directly or indirectly. Valuations for the available-for-sale securities are provided by independent pricing service providers who have experience in valuing these securities and by comparison to and/or average of quoted market prices obtained from independent brokers. We perform a monthly analysis on the values received from third parties to ensure that the prices represent a reasonable estimate of the fair value. The procedures include, but are not limited to, initial and ongoing review of third partythird-party pricing methodologies, review of pricing trends and monitoring of trading volumes. Additional corroboration, such as obtaining a non-binding price from a broker, may be obtained depending on the frequency of trades of the security and the level of liquidity or depth of the market. We ensure prices received from independent brokers represent a reasonable estimate of the fair value through the use of observable market inputs including comparable trades, yield curve, spreads and, when available, market indices. As a result of this analysis, if the Company determines that there is a more appropriate fair value based upon the available market data, the price received from the third party is adjusted accordingly. Below is a summary of the significant inputs used for each class of Level 2 assets and liabilities:
U.S. agency debentures: Fair value measurements of U.S. agency debentures are based on the characteristics specific to bonds held, such as issuer name, coupon rate, maturity date and any applicable issuer call option features. Valuations are based on market spreads relative to similar term benchmark market interest rates, generally U.S. Treasury securities.
Agency-issued mortgage-backed securities: Agency-issued mortgage-backed securities are pools of individual conventional mortgage loans underwritten to U.S. agency standards with similar coupon rates, tenor, and other attributes such as geographic location, loan size and origination vintage. Fair value measurements of these securities are based on observable price adjustments relative to benchmark market interest rates taking into consideration estimated loan prepayment speeds.
Agency-issued collateralized mortgage obligations: Agency-issued collateralized mortgage obligations are structured into classes or tranches with defined cash flow characteristics and are collateralized by U.S. agency-issued mortgage pass-through securities. Fair value measurements of these securities incorporate similar characteristics of mortgage pass-through securities such as coupon rate, tenor, geographic location, loan size and origination vintage, in addition to incorporating the effect of estimated prepayment speeds on the cash flow structure of the class or tranche. These measurements incorporate observable market spreads over an estimated average life after considering the inputs listed above.
Agency-issued commercial mortgage-backed securities: Fair value measurements of these securities are based on spreads to benchmark market interest rates (usually U.S. Treasury rates or rates observable in the swaps market), prepayment speeds, loan default rate assumptions and loan loss severity assumptions on underlying loans.
Municipal bonds and notes: Bonds issued by municipal governments generally have stated coupon rates, final maturity dates and are subject to being called ahead of the final maturity date at the option of the issuer. Fair value measurements

of these securities are priced based on spreads to other municipal benchmark bonds with similar characteristics; or, relative to market rates on U.S. Treasury bonds of similar maturity.
Interest rate derivative assets and liabilities: Fair value measurements of interest rate derivatives are priced considering the coupon rate of the fixed leg of the contract and the variable coupon on the floating leg of the contract. Valuation is based on both spot and forward rates on the swap yield curve and the credit worthiness of the contract counterparty.
Foreign exchange forward and option contract assets and liabilities: Fair value measurements of these assets and liabilities are priced based on spot and forward foreign currency rates and option volatility assumptions.
Equity warrant assets (public portfolio): Fair value measurements of equity warrant assets of publicly-traded portfolio companies are valued based on the Black-Scholes option pricing model. The model uses the price of publicly-traded companies (underlying stock price), stated strike prices, warrant expiration dates, the risk-free interest rate and market-observable option volatility assumptions.
Level 3
The fair value measurement is derived from valuation techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect our own estimates of assumptions we believe market participants would use in pricing the asset. Below is a summary of the valuation techniques used for each class of Level 3 assets:
Other ventureVenture capital investments:and private equity fund investments not measured at net asset value: Fair value measurements are based on consideration of a range of factors including, but not limited to, the price at which the investment was acquired, the term and nature of the investment, local market conditions, values for comparable securities, and as it relates to the private company, the current and projected operating performance, exit strategies and financing transactions subsequent to the acquisition of the investment. The significant unobservable inputs used in the fair value measurement include the information about each portfolio company, including actual and forecasted results, cash position, recent or planned transactions and market comparable companies. Significant changes to any one of these inputs in isolation could result in a significant change in the fair value measurement, however, we generally consider all factors available through ongoing communication with the portfolio companies and venture capital fund managers to determine whether there are changes to the portfolio company or the environment that indicate a change in the fair value measurement.
Other securities: Fair value measurements of equity securities of public companies are priced based on quoted market prices less a discount if the securities are subject to certain sales restrictions. Marketability discounts generally range from 10 percent to 20 percent depending on the duration of the sale restrictions which typically range from three to six months.
Equity warrant assets (public portfolio): Fair value measurements of equity warrant assets of publicly-traded portfolio companies are valued based on the Black-Scholes option pricing model. The model uses the price of publicly-traded companies (underlying stock price), stated strike prices, warrant expiration dates, the risk-free interest rate and market-observable option volatility assumptions. Modeled asset values are further adjusted by applying a discount of up to 20 percent for certain warrants that have lock-up restrictions or other features that indicate a discount to fair value is warranted. As a lock-up term nears, and other sale restrictions are lifted, discounts are adjusted downward to zero percent once all restrictions expire or are removed.
Equity warrant assets (private portfolio): Fair value measurements of equity warrant assets of private portfolio companies are priced based on a Black-Scholes option pricing model to estimate the asset value by using stated strike prices, option expiration dates, risk-free interest rates and option volatility assumptions. Option volatility assumptions used in the model are based on public market indices whose members operate in similar industries as companies in our private company portfolio. Option expiration dates are modified to account for estimates to actual life relative to stated expiration. Overall model asset values are further adjusted for a general lack of liquidity due to the private nature of the associated underlying company. There is a direct correlation between changes in the volatility and remaining life assumptions in isolation and the fair value measurement while there is an inverse correlation between changes in the liquidity discount assumption and the fair value measurement.
It is our policy to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements. When available, we use quoted market prices to measure fair value. If market prices are not available, fair value measurement is based upon valuation techniques that use primarily market-based or independently-sourced market parameters, including interest rate yield curves, prepayment speeds, option volatilities and currency rates. Substantially all of our financial instruments use the foregoing methodologies, and are categorized as a Level 1 or Level 2 measurement in the fair value hierarchy. However, in certain cases, when market observable inputs for our valuation techniques may not be readily available, we are required to make judgments about assumptions we believe market participants would use in estimating the fair value of the financial instrument, and based on the significance of those judgments, the measurement may be determined to be a Level 3 fair value measurement.

The degree of management judgment involved in determining the fair value of a financial instrument is dependent upon the availability of quoted market prices or observable market parameters. For financial instruments that trade actively and have quoted market prices or observable market parameters, there is minimal subjectivity involved in measuring fair value. When

observable market prices and parameters are not fully available, management judgment is necessary to estimate fair value. For inactive markets, there is little information, if any, to evaluate if individual transactions are orderly. Accordingly, we are required to estimate, based upon all available facts and circumstances, the degree to which orderly transactions are occurring and provide more weighting to price quotes that are based upon orderly transactions. In addition, changes in the market conditions may reduce the availability of quoted prices or observable data. For example, reduced liquidity in the capital markets or changes in secondary market activities could result in observable market inputs becoming unavailable. Therefore, when market data is not available, we use valuation techniques requiring more management judgment to estimate the appropriate fair value measurement. Accordingly, the degree of judgment exercised by management in determining fair value is greater for financial assets and liabilities categorized as Level 3.

(1)In determining the fair value of our other venture capital and private equity fund investment portfolio (not measured at net asset value), we evaluate a variety of factors related to each underlying private portfolio company including, but not limited to, actual and forecasted results, cash position, recent or planned transactions and market comparable companies. Additionally, we have ongoing communication with the portfolio companies and venture capital fund managers, to determine whether there is a material change in fair value. We use company provided valuation reports, if available, to support our valuation assumptions. These factors are specific to each portfolio company and a weighted average or range of values of the unobservable inputs is not meaningful.

(2)
We adjust quoted market prices of public companies, which are subject to certain sales restrictions. Sales restriction discounts generally range from 10 percent to 20 percent depending on the duration of the sales restrictions, which typically range from three to six months.

(3)Our marketability discount is applied to all private company warrants to account for a general lack of liquidity due to the private nature of the associated underlying company. The quantitative measure used is based upon various option-pricing models. On a quarterly basis, a sensitivity analysis is performed on our marketability discount.
(4)
We adjust the contractual remaining term of private company warrants based on our estimate of the actual remaining life, which we determine by utilizing historical data on cancellations and exercises. At September 30, 2017March 31, 2018, the weighted average contractual remaining term was 5.96.0 years, compared to our estimated remaining life of 2.7 years. On a quarterly basis, a sensitivity analysis is performed on our remaining life assumption.
For the three and nine months ended September 30,March 31, 2018 and 2017, and 2016, we did not have any transfers between Level 2 and Level 1 or transfers between Level 3 and Level 1. All transfers from Level 3 to Level 2 for the three and nine months ended September 30,March 31, 2018 and 2017 and 2016 were due to the transfer of equity warrant assets from our private portfolio to our public portfolio (see our Level 3 reconciliation above). All amounts reported as transfers represent the fair value as of the date of the change in circumstances that caused the transfer.

Financial Instruments not Carried at Fair Value
FASB guidance over financial instruments requires that we disclose estimated fair values for our financial instruments not carried at fair value. Fair value estimates, methods and assumptions, set forth below for our financial instruments, are made solely to comply with these requirements.
Fair values are based on estimates or calculations at the transaction level using present value techniques in instances where quoted market prices are not available. As broadly traded markets do not exist for many of our financial instruments, the fair value calculations attempt to incorporate the effect of current market conditions at a specific time. The aggregation of the fair value calculations presented herein does not represent, and should not be construed to represent, the underlying value of the Company.
The following describes the methods and assumptions used in estimating the fair values of financial instruments for which carrying value approximates fair value and estimated fair values of financial instruments not recorded at fair value on a recurring basis and excludes financial instruments and assets and liabilities already recorded at fair value as described above.
Financial Instruments for which Carrying Value Approximates Fair Value
Certain financial instruments that are not carried at fair value on the Consolidated Balance Sheets are carried at amounts that approximate fair value, due to their short-term nature and generally negligible credit risk. These instruments include cash and cash equivalents; FHLB and FRB stock; accrued interest receivable; short-term borrowings; short-term time deposits; and accrued interest payable. In addition, U.S. GAAP requires that the fair value of deposit liabilities with no stated maturity (i.e., demand, savings and certain money market deposits) be equal to their carrying value; recognition of the inherent funding value of these instruments is not permitted.

Estimated Fair Values of Financial Instruments Not Recorded at Fair Value on a Recurring Basis
Held-to-Maturity Securities
Held-to-maturity securities include similar investments held in our available-for-sale securities portfolio and are valued using the same methodologies. All securities included in our held-to-maturity securities portfolio are valued using Level 2 inputs. Refer to Level 2 fair value measurements above for significant inputs used in the valuation of our held-to-maturity investment securities.
Non-Marketable Securities (Cost and Equity Method Accounting)
Non-marketable securities includes other investments (equity method accounting), venture capital and private equity fund investments (cost method accounting), and other venture capital investments (cost method accounting). Other investments (equity method accounting) includes our investment in SPD-SVB, our joint venture bank in China. At this time, the carrying value of our investment in SPD-SVB is a reasonable estimate of fair value. The fair value of the remaining other investments (equity method accounting) and the fair value of venture capital and private equity fund investments (cost method accounting) and other venture capital investments (cost method accounting) is based on financial information obtained from the fund investments' or debt fund investments' respective general partners. For private company investments, estimated fair value is based on consideration of a range of factors including, but not limited to, the price at which the investment was acquired, the term and nature of the investment, local market conditions, values for comparable securities, current and projected operating performance, exit strategies, and financing transactions subsequent to the acquisition of the investment. For our fund investments, we utilize the net asset value per share as obtained from the general partners of the investments. We adjust the net asset value per share for differences between our measurement date and the date of the fund investment’s net asset value by using the most recently available financial information from the investee general partner, for example June 30th, for our September 30th consolidated

financial statements, adjusted for any contributions paid, distributions received from the investment, and significant fund transactions or market events during the reporting period.
Loans
The fair value of fixed and variable rate loans is estimated by discounting contractual cash flows using rates that reflect current pricing for similar loans and the projected forward yield curve. This method is not based on the exit price concept of fair value required under ASC 820, Fair Value Measurements and Disclosures.
Long-Term Deposits
The fair value of long-term time deposits is estimated by discounting the cash flows using our cost of borrowings and the projected forward yield curve over their remaining contractual term.
Long-Term Debt
The fair value of long-term debt is generally based on quoted market prices, when available, or is estimated based on calculations utilizing third-party pricing services and current market spread, price indications from reputable dealers or observable market prices of the underlying instrument(s), whichever is deemed more reliable. Also included in the estimated fair value of our 6.05% Subordinated Notes are amounts related to hedge accounting associated with the notes.
Off-Balance Sheet Financial Instruments
The fair value of net available commitments to extend credit is estimated based on the average amount we would receive or pay to execute a new agreement with identical terms and pricing, while taking into account the counterparties’ credit standing.
Letters of credit are carried at their fair value, which was equivalent to the residual premium or fee at September 30, 2017 and December 31, 2016. Commitments to extend credit and letters of credit typically result in loans with a market interest rate if funded.
The following fair value hierarchy table presents the estimated fair values of our financial instruments that are not carried at fair value at September 30, 2017March 31, 2018 and December 31, 20162017:

Investments in Entities that Calculate Net Asset Value Per Share
FASB guidance over certain fund investments requires that we disclose the fair value of funds, significant investment strategies of the investees, redemption features of the investees, restrictions on the ability to sell investments, estimate of the period of time over which the underlying assets are expected to be liquidated by the investee, and unfunded commitments related to the investments.
Our investments in debt funds and venture capital and private equity fund investments generally cannot be redeemed. Alternatively, we expect distributions, if any, to be received primarily through IPO and M&A activity of the underlying assets of the fund. Subject to applicable requirements under the Volcker Rule, we do not have any plans to sell any of these fund investments. If we decide to sell these investments in the future, the investee fund’s management must approve of the buyer before the sale of the investments can be completed. The fair values of the fund investments have been estimated using the net asset value per share of the investments, adjusted for any differences between our measurement date and the date of the fund investment’s net asset value by using the most recently available financial information from the investee general partner, for example June 30December 31thst, for our September 30March 31thst consolidated financial statements, adjusted for any contributions paid, distributions received from the investment, and significant fund transactions or market events during the reporting period.
The following table is a summary of the estimated fair values of these investments and remaining unfunded commitments for each major category of these investments as of September 30, 2017March 31, 2018:

Venture capital and private equity fund investments, debt funds, and other fund investments within non-marketable securities (equity and cost method accounting) include funds that invest in or lend money to primarily U.S. and global technology and life science/healthcare companies. It is estimated that we will receive distributions from the funds over the next 5 to 8 years, depending on the age of the funds and any potential extensions of the terms of the funds.
15.16.Legal Matters
Certain lawsuits and claims arising in the ordinary course of business have been filed or are pending against us and/or our affiliates, and we may from time to time be involved in other legal or regulatory proceedings. In accordance with applicable accounting guidance, we establish accruals for all such matters, including expected settlements, when we believe it is probable that a loss has been incurred and the amount of the loss is reasonably estimable. When a loss contingency is not both probable and estimable, we do not establish an accrual. Any such loss estimates are inherently uncertain, based on currently available information and are subject to management’s judgment and various assumptions. Due to the inherent subjectivity of these estimates and unpredictability of outcomes of legal proceedings, any amounts accrued may not represent the ultimate resolution of such matters.

To the extent we believe any potential loss relating to such matters may have a material impact on our liquidity, consolidated financial position, results of operations, and/or our business as a whole and is reasonably possible but not probable, we aim to disclose information relating to such potential loss. We also aim to disclose information relating to any material potential loss that is probable but not reasonably estimable. In such cases, where reasonably practicable, we aim to provide an estimate of loss or range of potential loss. No disclosures are generally made for any loss contingencies that are deemed to be remote.

Based upon information available to us, our review of lawsuits and claims filed or pending against us to date and consultation with our outside legal counsel, we have not recognized a material accrual liability for any such matters, nor do we currently expect that these matters will result in a material liability to the Company. However, the outcome of litigation and other legal and regulatory matters is inherently uncertain, and it is possible that one or more of such matters currently pending or threatened could have an unanticipated material adverse effect on our liquidity, consolidated financial position, results of operations, and/or our business as a whole, in the future.
16.17.Related Parties
We have no material related party transactions requiring disclosure. In the ordinary course of business, the Bank may extend credit to related parties, including executive officers, directors, principal shareholders and their related interests. Additionally, we provide real estate secured loans to eligible employees through our EHOP. For additional details, see Note 16—17—“Employee Compensation and Benefit Plans" under Part II, Item 8 of our 20162017 Form 10-K.

ITEM 2.  MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
Forward-Looking Statements
This Quarterly Report on Form 10-Q, including in particular “Management’s Discussion and Analysis of Financial Condition and Results of Operations” under Part I, Item 2 of this report, contains forward-looking statements within the meaning of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. In addition, management has in the past and might in the future make forward-looking statements orally to analysts, investors, the media and others. Forward-looking statements are statements that are not historical facts. Broadly speaking, forward-looking statements include, but are not limited to, the following:
Financial projections, including with respect to our net interest income, noninterest income, earnings per share, noninterest expenses (including professional services, compliance, compensation and other costs), cash flows, balance sheet positions, capital expenditures, liquidity and capitalization or other financial items;
Descriptions of our strategic initiatives, plans or objectives for future operations, including pending sales or acquisitions;
Forecasts of private equity/venture capital funding and investment levels;
Forecasts of future interest rates, economic performance, and income from investments;
Forecasts of expected levels of provisions for loan losses, nonperforming loans, loan growth and client funds; and
Descriptions of assumptions underlying or relating to any of the foregoing.
You can identify these and other forward-looking statements by the use of words such as “becoming,” “may,” “will,” “should,” "could," "would," “predict,” “potential,” “continue,” “anticipate,” “believe,” “estimate,” “assume,” “seek,” “expect,” “plan,” “intend,” the negative of such words, or comparable terminology. Forward-looking statements are neither historical facts nor assurances of future performance. Although we believe that the expectations reflected in these forward-looking statements are reasonable, we have based these expectations on our current beliefs as well as our assumptions, and such expectations may prove to be incorrect. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of our control. Our actual results of operations and financial performance could differ significantly from those expressed in or implied by our management’s forward-looking statements. Important factors that could cause our actual results and financial condition to differ from the expectations stated in the forward-looking statements include, among others:
Market and economic conditions, including the interest rate environment, and the associated impact on us;
The credit profile and credit quality of our loan portfolio and volatility of our levels of nonperforming assets and charge-offs;
The adequacy of our allowance for loan losses and the need to make provisions for loan losses for any period;
The borrowing needs of our clients;
The sufficiency of our capital and liquidity positions;
The levels of loans, deposits and client investment fund balances;

The performance of our portfolio investments; the general condition of the public and private equity and mergers and acquisitions markets and their impact on our investments, including equity warrant assets, venture capital and private equity funds and direct equity investments;
Our overall investment plans and strategies; the realization, timing, valuation and performance of our equity or other investments;
The levels of public offerings, mergers and acquisitions and venture capital investment activity of our clients that may impact the borrowing needs of our clients;

The occurrence of fraudulent activity, including breaches of our information security or cyber security-related incidents;
Business disruptions and interruptions due to natural disasters and other external events;
The impact on our reputation and business from our interactions with business partners, counterparties, service providers and other third parties;
Expansion of our business internationally, and the impact of international market and economic events on us;
The impact of governmental policy, legal requirements and regulations, including the Dodd-Frank Act, promulgated by the Federal Reserve and other regulatory requirements;
The impact of lawsuits and claims, as well as legal or regulatory proceedings;
The impact of changes in accounting standards and tax laws, (including any tax reform, such asincluding the proposedimpact of the Tax Cuts and Jobs Act);Act;
The levels of equity capital available to our client or portfolio companies;
The effectiveness of our risk management framework and quantitative models;
The sale of impaired assets;
Our ability to maintain or increase our market share, including through successfully implementing our business strategy and undertaking new business initiatives; and
Other factors as discussed in “Risk Factors” under Part I, Item 1A in our 20162017 Form 10-K.

We urge investors to consider all of these factors carefully in evaluating the forward-looking statements contained in this Quarterly Report on Form 10-Q. All subsequent written or oral forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by these cautionary statements. The forward-looking statements included in this filing are made only as of the date of this filing. We assume no obligation and do not intend to revise or update any forward-looking statements contained in this Quarterly Report on Form 10-Q, except as required by law.
The following discussion and analysis of financial condition and results of operations should be read in conjunction with our unaudited interim consolidated financial statements and accompanying notes as presented in Part I, Item 1 of this report and in conjunction with our 20162017 Form 10-K.

Overall, we had an outstanding thirdfirst quarter in 2017,2018, which was marked by higher net interest and core fee income, increased warrant gains, strong total client funds growth, healthy loan growth and stable credit quality. Additionally, we saw higher noninterest expense, primarily from increased compensation and benefits expenses as well as professional services expenses reflective of increased expenses to support our increasing regulatory, risk and compliance initiatives to support our domestic and global expansion as well as investments made in projects, systems and technology to support our revenue growth and related initiatives and other operating costs.expansion.

Critical Accounting Policies and Estimates
The accompanying management’s discussion and analysis of results of operations and financial condition is based upon our unaudited interim consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these financial statements in accordance with GAAP requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosure of contingent assets and liabilities. Management evaluates estimates and assumptions on an ongoing basis. Management bases its estimates on historical experiences and various other factors and assumptions that are believed to be reasonable under the circumstances. Actual results may differ materially from these estimates under different assumptions or conditions.
There have been no significant changes during the ninethree months ended September 30, 2017March 31, 2018 to the items that we disclosed as our critical accounting policies and estimates in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” under Part II, Item 7 of our 20162017 Form 10-K.
Results of Operations
Net Interest Income and Margin (Fully Taxable Equivalent Basis)
Net interest income is defined as the difference between interest earned on loans, fixed income investment portfolio (available-for-sale and held-to-maturity securities), short-term investment securities and interest paid on funding sources. Net interest income is our principal source of revenue. Net interest margin is defined as the amount of annualized net interest income, on a fully taxable equivalent basis, expressed as a percentage of average interest-earning assets. Net interest income and net interest margin are presented on a fully taxable equivalent basis to consistently reflect income from taxable loans and securities and tax-exempt securities based on the federal statutory tax rate of 35 percent.21.0 percent for the three months ended March 31, 2018 and 35.0 percent for the three months ended March 31, 2017.
Analysis of Net Interest Income Changes Due to Volume and Rate (Fully Taxable Equivalent Basis)
Net interest income is affected by changes in the amount and composition of interest-earning assets and interest-bearing liabilities, referred to as “volume change.” Net interest income is also affected by changes in yields earned on interest-earning assets and rates paid on interest-bearing liabilities, referred to as “rate change.” The following table sets forth changes in interest income for each major category of interest-earning assets and interest expense for each major category of interest-bearing liabilities. The table also reflects the amount of simultaneous changes attributable to both volume and rate changes for the periods indicated. For this table, changes that are not solely due to either volume or rate are allocated in proportion to the percentage changes in average volume and average rate.

Net Interest Income (Fully Taxable Equivalent Basis)
Three months ended September 30,March 31, 2018 and 2017 and 2016
Net interest income increased by $85.2$110.9 million to $374.6$421.2 million for the three months ended September 30, 2017,March 31, 2018, compared to $289.4$310.3 million for the comparable 20162017 period. Overall, our net interest income increased primarily from interest earned on loans, reflective of higher average loan balances driven by strong loan growth from our private equity/venture capital and SVB Private Banksoftware/internet loan portfolios and rate increases subsequent to September 30, 2016.March 31, 2017. In addition, we saw an increase in interest earned on our fixed income investment securities portfolio reflective of higher average fixed income investment securities balances driven by higher average deposit balances as well as an increase in yield from rate increases.
The main factors affecting interest income for the three months ended September 30, 2017,March 31, 2018, compared to the comparable 20162017 period are discussed below:
Interest income for the three months ended September 30, 2017March 31, 2018 increased by $85.2$112.5 million due primarily to:
A $54.2$69.7 million increase in interest income on loans to $268.4297.1 million for the three months ended September 30, 2017March 31, 2018, compared to $214.2227.3 million for the comparable 20162017 period. The increase was reflective of an increase in average loan balances of $2.93.7 billion and an increase in the overall loan yield of 3647 basis points to 4.935.06 percent from 4.574.59 percent. Gross loan yields, excluding loan interest recoveries and loan fees, increased 3749 basis points to 4.304.52 percent from 3.934.03 percent, reflective primarily of the benefit of interest rate increases. Loan fee yields were flat at 61down four basis points to 51 basis points for both the three months ended September 30, 2017 and 2016.March 31, 2018.
A $27.0$40.1 million increase in interest income on fixed income investment securities to $111.2130.9 million for the three months ended September 30, 2017March 31, 2018, compared to $84.390.8 million for the comparable 20162017 period. The increase was reflective of an increase in average fixed income investments of $2.4$2.8 billion due to growth in average deposit balances and an increase in our fixed income investment securities yield of 2947 basis points to 1.912.21 percent from 1.62 percent resulting primarily from higher reinvestment yields on maturing fixed income investments as well as higher yields on new purchases due to interest rate increases.

A $4.0 million increase in interest income from our interest earning cash and short-term investment securities. The increase was due primarily to an increase of $0.9 billion in average interest-earning cash balances as a result of a $6.1 billion increase in average deposit balances and from the impact of the recent increases in the Federal Funds target rate.
The main factors affecting interest income and interest expense for the nine months ended September 30, 2017, compared to the comparable 2016 period are discussed below:
Interest income for the nine months endedSeptember 30, 2017 increased by $174.6 million due primarily to:
A $128.5 million increase in interest income on loans to $746.0 million for the nine months endedSeptember 30, 2017, compared to $617.5 million for the comparable 2016 period. The increase was reflective of an increase in average loan balances of $2.8 billion and an increase in the overall loan yield of 22 basis points to 4.81 percent from 4.59 percent. Gross loan yields, excluding loan interest recoveries and loan fees, increased to 4.18 percent from 3.99 percent, reflective of the benefit of interest rate increases, partially offset by the strong growth of our lower yielding private equity/venture capital and Private Bank loan portfolios. Our private equity/venture capital loan portfolio represented 43.1 percent and 38.8 percent of our total gross loan portfolio at September 30, 2017 and 2016, respectively. Our Private Bank loan portfolio represented 11.2 percent and 10.8 percent of our total gross loan portfolio at September 30, 2017 and 2016, respectively.
Loan fee yields increased two basis points to 60 basis points from 58 basis points in the comparable 2016 period. The increase in loan fee yields was primarily a result of higher income from loan prepayments.
A $35.2 million increase in interest income on fixed income investment securities to $298.9 million for the nine months endedSeptember 30, 2017, compared to $263.7 million for the comparable 2016 period. The increase was primarily reflective of an increase in our fixed income investment securities yield of 21 basis points to 1.82 percent from 1.611.74 percent resulting primarily from higher reinvestment yields on maturing fixed income investments as well as higher yields on new purchases due to interest rate increases.
A $10.9$2.6 million increase in interest income from our interest earning cash and short-term investment securities. The increase was due primarily to an increase of $1.1 billion in average interest-earning cash balanceshigher yields as a result of a $3.6 billion increase in average deposit balances. We also saw a benefit from the impact of the recent increases in the Federal Funds target rate.

Interest expensefor the ninethree months ended September 30, 2017March 31, 2018 increased by $1.3$1.6 million due primarily due to:
AnA $2.4 million increase in deposits interest expense, of $2.2 million, due primarily to an increase in interest paid on our interest-bearing money market deposits as a result of market rate adjustments.
A $0.8 million decrease in borrowings interest expense, due mostly to the repayment of our 6.05% Subordinated Notes and the redemption of our Junior Subordinated Debentures in 2017.
Net Interest Margin (Fully Taxable Equivalent Basis)
Three months ended September 30,March 31, 2018 and 2017 and 2016
Our net interest margin increased by 3550 basis points to 3.103.38 percent for the three months ended September 30, 2017March 31, 2018, compared to 2.752.88 percent for the comparable 20162017 period. The higher margin during the thirdfirst quarter of 20172018 was reflective primarily of the increases in the Federal Funds target rate since the thirdfirst quarter of 2016.2017 as well as a shift in the mix of interest-earning assets to higher-yielding loans from our fixed income investment securities.
Nine months ended September 30, 2017 and 2016
Our net interest margin increased by 27 basis points to 2.99 percent for the nine months endedSeptember 30, 2017, compared to 2.72 percent for the comparable 2016 period. Our net interest margin increased primarily as a result of the impact of rising interest rates and a higher level of loans as a percentage of our interest-earning assets portfolio during the nine months ended September 30, 2017. Average loans represented 45 percent of year-to-date interest earning assets compared to 43 percent for the comparable 2016 period.



Average Balances, Yields and Rates Paid (Fully Taxable Equivalent Basis)
The average yield earned on interest-earning assets is the amount of annualized fully taxable equivalent interest income expressed as a percentage of average interest-earning assets. The average rate paid on funding sources is the amount of annualized interest expense expressed as a percentage of average funding sources. The following tables set forth average assets, liabilities, noncontrolling interests and SVBFG stockholders’ equity, interest income, interest expense, annualized yields and rates, and the composition of our annualized net interest margin for the three and nine months ended September 30, 2017March 31, 2018 and 20162017:

Provision for Credit Losses
The provision for credit losses is the combination of both the provision for loan losses and the provision for unfunded credit commitments. Our provision for loan losses is a function of our reserve methodology, which is used to determine an appropriate allowance for loan losses for the period. Our reserve methodology is based on our evaluation of the existing allowance for loan losses in relation to total gross loans using historical and other objective information, and on our qualitative assessment of the inherent and identified credit risk of the loan portfolio. Our provision for unfunded credit commitments is determined using a methodology that is similar to the methodology used for calculating the allowance for loan losses, adjusted for factors specific to binding commitments, including the probability of funding and exposure at funding. Our provision for credit losses equals our best estimate of probable credit losses that are inherent in the portfolios at the balance sheet date.
The following table summarizes our allowance for loan losses and the allowance for unfunded credit commitments for the three and nine months ended September 30, 2017March 31, 2018 and 2016:2017:

The provision for loan losses of $22.4$27.0 million for the three months ended September 30, 2017March 31, 2018 primarily reflects $13.8 million in net new specific reserves for nonaccrual loans and a $10.9$14.0 million increase in reserves for period-end loan growth and $11.3 million in specific reserves for net new nonaccrual loans.

offset by a benefit from overall improved credit quality of ourGross loan portfolio and the continued shift in our loan portfolio to private equity/venture capital loans, which tend to be of higher credit quality.

The net increase in reserves for nonaccrual loans included a $5.5 million partial reserve release for one of our non-performing sponsored buyout loans due to credit improvement.
Gross loan charge-offs were $12.3 million for three months ended September 30, 2017,March 31, 2018, of which $6.3$3.4 million was not specifically previously reserved for.for at December 31, 2017.

Noninterest Income
For the three and nine months ended September 30, 2017,March 31, 2018, noninterest income was $158.8$155.5 million, and $405.0 million, respectively, compared to $144.1 million and $343.1$117.7 million for the comparable 2016 periods.2017 period. For the three and nine months ended September 30, 2017,March 31, 2018, non-GAAP noninterest income, net of noncontrolling interests was $153.2$142.5 million, and $383.3 million, respectively, compared to $139.5 million and $339.4$111.1 million for the comparable 2016 periods.2017 period. For the three and nine months ended September 30, 2017,March 31, 2018, non-GAAP core fee income was $102.7$115.0 million, and $272.6 million, respectively, compared to $80.5 million and $231.5$82.6 million for the comparable 2016 periods.2017 period. (See reconciliations of non-GAAP measures used below under “Use of Non-GAAP Financial Measures”.)
Use of Non-GAAP Financial Measures
To supplement our unaudited interim consolidated financial statements presented in accordance with GAAP, we use certain non-GAAP measures of financial performance (including, but not limited to, non-GAAP core fee income, non-GAAP noninterest income, non-GAAP net gains on investment securities). These supplemental performance measures may vary from, and may not be comparable to, similarly titled measures by other companies in our industry. Non-GAAP financial measures are not in accordance with, or an alternative for, GAAP. Generally, a non-GAAP financial measure is a numerical measure of a company’s performance that either excludes or includes amounts that are not normally excluded or included in the most directly comparable

measure calculated and presented in accordance with GAAP. A non-GAAP financial measure may also be a financial metric that is not required by GAAP or other applicable requirement.
We believe these non-GAAP financial measures, when taken together with the corresponding GAAP financial measures, provide meaningful supplemental information regarding our performance by excluding items that represent income attributable to investors other than us and our subsidiaries and other certain non-recurring items. Our management uses, and believes that investors benefit from referring to, these non-GAAP financial measures in assessing our operating results and when planning, forecasting and analyzing future periods. However, these non-GAAP financial measures should be considered in addition to, not as a substitute for or preferable to, financial measures prepared in accordance with GAAP.
Included in net income is income and expense attributable to noncontrolling interests. We recognize, as part of our investment funds management business through SVB Capital, the entire income or loss from funds consolidated in accordance with ASC Topic 810 as discussed in Note 1—“Basis of Presentation” of the “Notes to Interim Consolidated Financial Statements (unaudited)” under Part I, Item 1 of this report. We are required under GAAP to consolidate 100% of the results of these entities, even though we may own less than 100% of such entities. The relevant amounts attributable to investors other than us are reflected under “Net Income Attributable to Noncontrolling Interests” on our statements of income. Where applicable, the tables below for noninterest income and net gains on investment securities exclude noncontrolling interests.
Core fee income is a non-GAAP financial measure, which represents GAAP noninterest income, but excludes certain line items where performance is typically subject to market or other conditions beyond our control.control, primarily our net gains (losses) on investment securities and equity warrant assets. Core fee income includes foreign exchange fees, credit card fees, deposit service charges, credit card fees, lending related fees, client investment fees and letters of credit and standby letters of credit fees.
The following table provides a reconciliation of GAAP noninterest income to non-GAAP noninterest income, net of noncontrolling interests, for the three and nine months ended September 30, 2017March 31, 2018 and 2016:2017:

Gains on Investment Securities, Net
Net gains and losses on investment securities include gains and losses from our non-marketable and other equity securities, as well as gains and losses from sales of our available-for-saleAFS securities portfolio, when applicable.
Our available-for-sale securities portfolio represents primarily interest-earning fixed income investment securities and is managed to earn an appropriate portfolio yield over the long-term while maintaining sufficient liquidity and addressing our asset/liability management objectives. Sales of equity securities held as a result of our exercised warrants, result in net gains or losses on investment securities. These sales are conducted pursuant to the guidelines of our investment policy related to the

management of our liquidity position and interest rate risk. Though infrequent, sales of investment securities in our available-for-sale securities portfolio may result in net gains or losses and are also conducted pursuant to the guidelines of our investment policy.
Our non-marketable and other equity securities portfolio primarily represents investments in venture capital and private equity funds, SPD Silicon Valley Bank Co., Ltd. (the Bank's joint venture bank in China (“SPD-SVB”)), debt funds, private and public portfolio companies and investments in qualified affordable housing projects. We experience variability in the performance of our non-marketable and other equity securities from quarterperiod to quarter,period, which results in net gains or losses on investment securities (both realized and unrealized). This variability is due to a number of factors, including unrealized changes in the values of our investments, changes in the amount of realized gains and losses from distributions, changes in liquidity events and general economic and market conditions. Unrealized gains or losses from non-marketable and other equity securities for any single period are typically driven by valuation changes, and are therefore subject to potential increases or decreases in future periods. Such variability may lead to volatility in the gains or losses from investment securities. As such, our results for a particular period are not necessarily indicative of our expected performance in a future period.
The extent to which any unrealized gains or losses will become realized is subject to a variety of factors, including, among other things, the expiration of certain sales restrictions to which these equity securities may be subject to (i.e. lock-up agreements), changes in prevailing market prices, market conditions, the actual sales or distributions of securities, the timing of such actual sales or distributions, which, to the extent such securities are managed by our managed funds, are subject to our funds' separate discretionary sales/distributions and governance processes.
Our AFS securities portfolio represents primarily interest-earning fixed income investment securities and is managed to earn an appropriate portfolio yield over the long-term while maintaining sufficient liquidity and addressing our asset/liability management objectives. Sales of equity securities held as a result of our exercised warrants, result in net gains or losses on investment securities. These sales are conducted pursuant to the guidelines of our investment policy related to the management of our liquidity position and interest rate risk. Though infrequent, sales of investment securities in our AFS securities portfolio may result in net gains or losses and are also conducted pursuant to the guidelines of our investment policy.
Three months ended September 30,March 31, 2018 and 2017 and 2016
For the three months ended September 30, 2017,March 31, 2018, we had net gains on investment securities of $15.2$9.1 million, compared to $23.2$16.0 million for the comparable 20162017 period.

Three months ended September 30, 2017 and 2016
Total other noninterest income was $15.9 million for the three months ended September 30, 2017, compared to $18.9 million for the comparable 2016 period. The decrease of $3.0 million in other noninterest income was due to the following:
Service-based fee income of $0.5 million compared to $2.0 million for the comparable 2016 period. The $1.5 million decrease was primarily due to the sale of our equity valuation services business during the third quarter of 2017, and
Other noninterest income of $10.3 million compared to $11.4 million for the comparable 2016 period. The $1.1 million decrease was primarily attributable to higher carried interest income earned from one of our unconsolidated fund investments during the third quarter of 2016 as compared to the third quarter of 2017.
Nine months ended September 30, 2017 and 2016
Total other noninterest income was $41.1 million for the nine months endedSeptember 30, 2017, compared $36.5 million for the comparable 2016 period. The increase of $4.6 million in other noninterest income was due to the following:
Fund management fees of $15.9 million compared to fees of $14.1 million for the comparable 2016 period. The increase was due primarily to the addition of new managed funds at SVB Capital,
Service-based fee income of $3.9 million compared to $6.3 million for the comparable 2016 period. The $2.4 million decrease was primarily due to the sale of our equity valuation services business during the third quarter of 2017,
Net gains of $0.5 million on client foreign exchange forward contracts and the revaluation of client foreign currency denominated cash for the nine months ended September 30, 2017, compared to net losses of $1.8 million for the comparable 2016 period. The net losses for the nine months ended September 30, 2016 was primarily due to a reclassification of $2.8 million in unrealized gains on forward contracts to foreign exchange fee income reflecting fees earned on forward contracts executed on behalf of our clients that were previously recorded in gains on derivative instruments, and

Net gains of $0.9 million on internal foreign exchange forward contracts and the revaluation of internal foreign currency denominated cash for the nine months ended September 30, 2017, compared to net losses of $1.2 million for the comparable 2016 period. The net losses of $1.2 million for the nine months ended September 30, 2016 were primarily due to the strengthening of the U.S. dollar against various foreign currencies during the nine months ended September 30, 2016.

(1)Our consolidated statements of income were modified from prior periods' presentation to the current period presentation, which reflects our provision for loan losses and provision for unfunded credit commitments together as our “provision for credit losses”. In prior periods, our provision for unfunded credit commitments were reported separately as a component of noninterest expense.
Included in noninterest expense is expense attributable to noncontrolling interests. See below for a description and reconciliation of non-GAAP noninterest expense and non-GAAP operating efficiency ratio, both of which exclude noncontrolling interests.
Non-GAAP Noninterest Expense
We use and report non-GAAP noninterest expense, non-GAAP taxable equivalent revenue and non-GAAP operating efficiency ratio, which excludes noncontrolling interests. We believe these non-GAAP financial measures, when taken together with the corresponding GAAP financial measures, provide meaningful supplemental information regarding our performance by: (i) excluding certain items that represent expenses attributable to investors other than us and our subsidiaries, or certain items that do not occur every reporting period; or (ii) providing additional information used by management that is not otherwise required by GAAP or other applicable requirements. Our management uses, and believes that investors benefit from referring to, these non-GAAP financial measures in assessing our operating results and when planning, forecasting and analyzing future periods. However, these non-GAAP financial measures should be considered in addition to, not as a substitute for or preferable to, financial measures prepared in accordance with GAAP.

The table below provides a summary of non-GAAP noninterest expense and non-GAAP operating efficiency ratio, both net of noncontrolling interests for the three and nine months ended September 30, 2017March 31, 2018 and 20162017:

Net Income Attributable to Noncontrolling Interests
Included in net income is income and expense attributable to noncontrolling interests. The relevant amounts allocated to investors in our consolidated subsidiaries, other than us, are reflected under “Net income attributable to noncontrolling interests” on our statements of income.
In the table below, noninterest income consists primarily of net investment gains and losses from our consolidated funds. Noninterest expense is primarily related to management fees paid by our managed funds to SVB Financial’s subsidiaries as the funds’ general partners. A summary of net income attributable to noncontrolling interests for the three and nine months ended September 30,March 31, 2018 and 2017 and 2016 is as follows:

Three months ended September 30,March 31, 2018 and 2017 and 2016
Net income attributable to noncontrolling interests was $5.513.1 million for the three months ended September 30, 2017,March 31, 2018, compared to $4.6$6.4 million for the comparable 20162017 period. Net income attributable to noncontrolling interests of $5.5$13.1 million for the three months ended September 30, 2017March 31, 2018 was primarily a result of net gains on investment securities (including carried interest allocation) from our managed funds of funds portfolio duerelated to net unrealized valuation increases ofin the investments held by the funds driven primarily by IPO and M&A activity.during the first quarter of 2018. See “Results of Operations—Noninterest Income—Gains on Investment Securities, Net”.
Nine months ended September 30, 2017 and 2016
Net income attributable to noncontrolling interests was $21.2 million for the nine months ended September 30, 2017, compared to $3.4 million for the comparable 2016 period. Net income attributable to noncontrolling interests of $21.2 million for the nine months ended September 30, 2017 was primarily a result of net gains on investment securities (including carried interest allocation) from our managed funds of funds portfolio due to net unrealized valuation increases of investments held by the funds driven by IPO, M&A and private equity-backed financing activity. See “Results of Operations—Noninterest Income—Gains on Investment Securities, Net”.
Income Taxes
On December 22, 2017, the TCJ Act was signed into law. The TCJ Act amends the Internal Revenue Code to, among other things, reduce tax rates, and make changes to credits and deductions for individuals and businesses. For businesses, the TCJ Act permanently lowers the Federal corporate tax rate to 21 percent from the prior maximum rate of 35 percent, effective for tax years including or commencing January 1, 2018.
The Company has also considered the provisions of the TCJ Act related to non-U.S. operations which would potentially impact the Company’s income tax provision. Such provisions include the one-time transition tax (“TT”) on foreign earnings and the new base erosion anti-avoidance tax (“BEAT”). Based on analyses performed by the Company as of March 31, 2018, the impact of both of these provisions will have an immaterial impact on the Company’s income tax provision.
Our effective income tax expense rate was 39.6 percent and 37.127.5 percent for the three and nine months ended September 30, 2017, respectively,March 31, 2018, compared to 40.9 percent and 40.833.6 percent for the three and nine months ended September 30, 2016, respectively.March 31, 2017. Our effective tax rate is calculated by dividing income tax expense by the sum of income before income tax expense and the net income attributable to noncontrolling interests.
The reductionsreduction in the effective tax rate for the three and nine months ended September 30,March 31, 2018 is primarily due to the lower Federal corporate tax rate as a result of the TCJ Act effective January 1, 2018, partially offset by the period-over-period reduction in tax benefits associated with employee stock transactions and a one-time benefit of $4.7 million recorded in the period ended March 31, 2017, resulted fromfor the return of tax funds related to a prior year's tax return. The effective tax rate for the three months ended March 31, 2018, and March 31, 2017, also included the recognition of a tax benefitbenefits of $1.3$2.5 million and $14.4$6.1 million, respectively, due to the adoption and implementation of Accounting Standards Update (“ASU”)ASU 2016-09 Improvements to Employee Share-Based Payment Accounting, in the first quarter of 2017. 
The new guidance requires tax impacts from employee share-based transactions to be recognized inCompany has considered the provision for income taxes rather than additional paid-in-capital in stockholders' equity required under the previous guidance. Additionally, our effective income tax expense rate for the nine months ended September 30, 2017 included the recognitionprovisions of a tax benefit of $4.7 million reflective of the return of tax funds related to a prior years' tax return.
Additionally, in early November 2017, draft tax reform legislation entitled the Tax Cuts and Jobs Act (the “TCJ Act”) was introduced.  If enacted, the TCJ Act would make significant changesand analyzed for potential impact to its income tax provision for the U.S. Internal Revenue Codefiscal year ending December 31, 2018. Aside from the items noted above, the Company is not aware of 1986, including corporate taxation provisions.  Such changes underany further items which could materially impact its financial statements for the TCJ Act or any other similar tax reform could have a material impact on our results of operations or financial condition.quarter ended March 31, 2018.
Excluding the impact of the tax benefit items discussed above and any tax reform, we expect the annual effective tax rate for 2017 to be comparable to the full-year 2016 effective tax rate.

Three months ended September 30,March 31, 2018 and 2017 and 2016
Income before income tax expense from our Global Commercial Bank (“GCB”) increased to $237.2$259.2 million for the three months ended September 30, 2017,March 31, 2018, compared to $165.3$153.6 million for the comparable 20162017 period, which reflected the continued acquisition of new clients and growth of our core commercial business. The key components of GCB's performance for the three months ended September 30, 2017March 31, 2018 compared to the comparable 20162017 period are discussed below.
Net interest income from GCB increased by $75.4$94.0 million for the three months ended September 30, 2017,March 31, 2018, due primarily to an increase in loan interest income resulting mainly from higher average loan balances, as well as from an increase in loan yields as a result of rate increases.
GCB had a provision for credit losses of $20.9$25.3 million for the three months ended September 30, 2017,March 31, 2018, compared to $17.0$28.9 million for the comparable 20162017 period. The provision of $20.9$25.3 million for the three months ended September 30, 2017March 31, 2018 primarily reflected $13.8$11.3 million in net new specific reserves for nonaccrual loans and a $10.9$14.0 million increase in reserves for period-end loan growth, partially offset by a benefit from overall improved credit quality of our loan portfolio and the continued shift in our loan portfolio to private equity/venture capital loans, which tend to be of higher credit quality.growth.
The provision of $17.0$28.9 million for the three months ended September 30, 2016March 31, 2017 primarily reflected $8.0$25.4 million ofin specific reserves for performingnet new accrual loans $5.5and a $5.0 million increase in charge-offs that did not previously have a specific reserve, $3.0 million net reserves for nonaccrual loans and $2.8 million forperiod-end loan growth.
Noninterest income increased by $18.0$19.8 million for the three months ended September 30, 2017,March 31, 2018, related primarily to an increase across our non-GAAP core fee income (higher foreign exchange fees, client investment fees and credit card fees). This increase was due primarily to the continued growth of our client base and work with larger global companies reflective of investments in our platform, capabilities and global reach.
Noninterest expense increased by $17.5$11.8 million for the three months ended September 30, 2017,March 31, 2018, due primarily to increased professional services expense and compensation and benefits expense. Professional services expenses were higher due to enhancements in our risk and compliance infrastructure to support our momentum as we continue to grow both domestically and globally as well as investments made in projects, systems and technology to support our revenue growth and related initiatives and other operating costs. Compensation and benefits expense increased as a result of increased salaries and wages and other employee benefits. The increase in GCB salaries and wages was due primarily to an increase in the average number of FTEs at GCB, which increased by 11183 to 1,8811,929 FTEs for the three months ended September 30, 2017,March 31, 2018, compared to 1,7701,846 FTEs for the comparable 20162017 period. The increase in total other employee benefits was related to various expenses, particularly personnel contracting expenses, to support our growth both domestically and globally, and employer payroll taxes reflective of our increased headcount since the thirdfirst quarter 2016.
Nine months ended September 30, 2017 and 2016
Net interest income from our GCB increased by $151.4 million for the nine months ended September 30, 2017, due primarily to an increase in loan interest income resulting mainly from higher average loan balances as well as from an increase in loan yields as a result of rate increases.2017.

GCB had a provision for credit losses of $65.0 million for the nine months ended September 30, 2017, compared to a provision of $86.1 million for the comparable 2016 period. The provision of $65.0 million for the nine months ended September 30, 2017 was reflective primarily of $51.9 million in net new specific reserves for nonaccrual loans and $20.9 million from period-end loan growth, partially offset by a benefit from overall improved credit quality of our loan portfolio and the continued shift in our loan portfolio to private equity/venture capital loans, which tend to be of higher credit quality.
The provision of $86.1 million for the nine months ended September 30, 2016 was reflective of $33.0 million in charge-offs that did not previously have a specific reserve and $23.0 million from period-end loan growth, with the remaining provision due primarily to reserves for new nonaccrual loans.
Noninterest income increased by $29.4 million for the nine months ended September 30, 2017, related primarily to an increase across our non-GAAP core fee income (higher foreign exchange fees, credit card fees and client investment fees). This increase was due primarily to the continued growth of our client base and work with larger global companies reflective of investments in our platform, capabilities and global reach.
Noninterest expense increased by $62.8 million for the nine months ended September 30, 2017, due primarily to increased expenses for compensation and benefits and professional services. Compensation and benefits expense increased as a result of higher incentive compensation expenses, increased salaries and wages and higher other employee benefits. The increase in incentive compensation expenses was due to the expectation of our performance to exceed budget for 2017. The increase in our salaries and wages expenses was due primarily to an increase in the average number of FTEs at GCB, which increased by 124 to 1,857 FTEs for the nine months ended September 30, 2017, compared to 1,733 FTEs for the comparable 2016 period. The increase in total other employee incentives and benefits was related to various expenses, particularly personnel contracting expenses, to support our growth both domestically and globally as well as group health and life insurance and employer payroll taxes reflective of our increased headcount since the nine months ended September 30, 2016. Professional services expenses were higher due to enhancements in our risk and compliance infrastructure to support our momentum as we continue to grow both domestically and globally as well as investments made in projects, systems and technology to support our revenue growth and related initiatives and other operating costs.

SVB Capital’s components of noninterest income primarily include net gains and losses on non-marketable and other equity securities, carried interest and fund management fees. All components of income before income tax expense and average assets discussed below are net of noncontrolling interests.
We experience variability in the performance of SVB Capital from quarter to quarter due to a number of factors, including changes in the values of our funds’ underlying investments, changes in the amount of distributions and general economic and market conditions. Such variability may lead to volatility in the gains and losses from investment securities and cause our results to differ from period to period.

The increaseslight decrease in period-end cash balances wasrelated primarily due to growth in our deposit balancesthe reinvestment of maturing fixed income securities during the ninethree months ended September 30, 2017.March 31, 2018.
As of September 30, 2017 and DecemberMarch 31, 2016, $1.62018, $0.4 billion and $1.1 billion, respectively, of our cash and due from banks was deposited at the Federal Reserve Bank and was earning interest at the Federal Funds target rate, and interest-earning deposits in other financial institutions were $1.21.1 billion.

Period-end available-for-sale securities were $12.6$10.1 billion at September 30, 2017March 31, 2018 compared to $12.6$11.1 billion at December 31, 2016,2017, a decrease of $17.1 million,$1.0 billion, or 0.19.4 percent. The $17.1 million$1.0 billion decrease in period-end AFS securities balances from the fourth quarter of 20162017 to the thirdfirst quarter of 20172018 was due primarily to $2.4$0.9 billion in portfolio paydowns and maturities offset by purchases of $2.4 billion of agency backed mortgage securities and U.S. Treasury securities.
maturities. Securities classified as available-for-sale are carried at fair value with changes in fair value recorded as unrealized gains or losses in a separate component of stockholders' equity. During the first quarter of 2018 the AFS portfolio had unrealized losses of $58.0 million ($42.1 million net of tax), primarily driven by increases in period-end market interest rates.
The following table summarizes the remaining contractual principal maturities and fully taxable equivalent yields on fixed income securities, carried at fair value, classified as available-for-sale as of September 30, 2017.March 31, 2018. The weighted average yield is computed using the amortized cost of fixed income investment securities, which are reported at fair value. For U.S. Treasury securities and U.S. agency debentures, the expected maturity is the actual contractual maturity of the notes. Expected remaining maturities for certain U.S. agency debentures may occur earlier than their contractual maturities because the note issuers have the right to call outstanding amounts ahead of their contractual maturity. Expected maturities for mortgage-backed securities may differ significantly from their contractual maturities because mortgage borrowers have the right to prepay outstanding loan obligations with or without penalties. Mortgage-backed securities classified as available-for-sale typically have original contractual maturities from 10 to 30 years whereas expected average lives of these securities tend to be significantly shorter and vary based upon structure and prepayments in lower interest rate environments. The weighted average yield on mortgage-backed securities is based on prepayment assumptions at the purchase date. Actual yields earned may differ significantly based upon actual prepayments.

The $2.7$1.8 billion increase in period-end HTM security balances from the fourth quarter of 2016December 31, 2017 to the third quarter of 2017March 31, 2018 was due to new purchases of $3.9$2.4 billion, primarily inwith $1.9 billion of agency backed mortgage securities purchases and $0.3 billion of municipal bond purchases, partially offset by $1.2$0.5 billion in portfolio paydowns and maturities.
Securities classified as held-to-maturity are accounted for at cost with no adjustments for changes in fair value. For securities previously re-designated as held-to-maturity from available-for-sale, the net unrealized gains at the date of transfer will continue to be reported as a separate component of shareholders' equity and amortized over the life of the securities in a manner consistent with the amortization of a premium or discount.
The following table summarizes the remaining contractual principal maturities and fully taxable equivalent yields on fixed income investment securities classified as held-to-maturity as of September 30, 2017.March 31, 2018. Interest income on certain municipal bonds and notes (non-taxable investments) are presented on a fully taxable equivalent basis using the federal statutory tax rate of 3521 percent. The weighted average yield is computed using the amortized cost of fixed income investment securities. For U.S. agency

debentures, the expected maturity is the actual contractual maturity of the notes. Expected maturities for mortgage-backed securities may differ significantly from their

contractual maturities because mortgage borrowers have the right to prepay outstanding loan obligations with or without penalties. Mortgage-backed securities classified as held-to-maturity typically have original contractual maturities from 10 to 30 years whereas expected average lives of these securities tend to be significantly shorter and vary based upon structure and prepayments in lower interest rate environments. The weighted average yield on mortgage-backed securities is based on prepayment assumptions at the purchase date. Actual yields earned may differ significantly based upon actual prepayments.

Portfolio duration is a standard measure used to approximate changes in the market value of fixed income instruments due to a change in market interest rates. The measure is an estimate based on the level of current market interest rates, expectations for changes in the path of forward rates and the effect of forward rates on mortgage prepayment speed assumptions. As such, portfolio duration will fluctuate with changes in market interest rates. Changes in portfolio duration are also impacted by changes in the mix of longer versus shorter term-to-maturity securities. Our estimated fixed income investment securities portfolio duration was 2.73.4 years and 2.53.0 years at September 30, 2017March 31, 2018 and December 31, 2016,2017, respectively.

Non-Marketable and Other Equity Securities
Our non-marketable and other equity securities portfolio primarily represents investments in venture capital and private equity funds, SPD Silicon Valley Bank Co., Ltd. (the Bank's joint venture bank in China (“SPD-SVB”)), debt funds, private and public portfolio companies, including public equity securities held as a result of equity warrant assets exercised, and investments in qualified affordable housing projects. Included in our non-marketable and other equity securities carried under fair value accounting are amounts that are attributable to noncontrolling interests. We are required under GAAP to consolidate 100% of these investments that we are deemed to control, even though we may own less than 100% of such entities. See below for a summary of the carrying value (as reported) of non-marketable and other securities compared to the amounts attributable to SVBFG.
Period-end non-marketable and other equity securities were $627.5$824.9 million at September 30, 2017March 31, 2018 compared to $622.6$651.1 million at December 31, 2016,2017, an increase of $4.9$173.8 million, or 0.826.7 percent. Non-marketable and other equity securities, net of noncontrolling interests were $506.1$699.4 million at September 30, 2017,March 31, 2018, compared to $500.1$530.6 million at December 31, 2016.2017. The increase was mostly attributable to accounting changes related to the adoption of ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, which requires equity investments (except those accounted for under the equity method of accounting) to be measured at fair value and eliminated the cost method of accounting. As part of this adoption we recorded an adjustment to opening retained earnings for cost method investments measured at NAV and increased the carrying value of our unconsolidated venture capital and private equity fund investments. We also increased our investment in qualified affordable housing projects by $51.6 million for additional tax benefits as part of our strategy to reduce our effective tax rate. The following table summarizes the carrying value (as reported) of non-marketable and other securities compared to the amounts attributable to SVBFG (which generally represents the carrying value times our ownership percentage) at September 30, 2017March 31, 2018 and December 31, 2016:2017:

The following table shows the amounts of othercarrying value represents investments in 229 and 235 funds (primarily venture capital investments held by the following consolidated funds and amounts attributable to SVBFG for each fundfunds) at September 30, 2017March 31, 2018 and December 31, 20162017:, respectively, where our ownership interest is typically less than 5% of the voting interests of each such fund and in which we do not have the ability to exercise significant influence over the partnerships' operating activities and financial policies. Effective January 1, 2018, we adopted ASU 2016-01 Recognition and Measurement of Financial Assets and Financial Liabilities which eliminated the concept of cost method accounting. On a prospective basis we will carry our unconsolidated venture capital and private equity fund investments at fair value based on the fund investments' net asset values per share as obtained from the general partners of the funds. We will adjust the net asset value per share for differences between our measurement date and the date of the fund investment’s net asset value by using the most recently available financial information from the investee general partner, for example, December 31st, for our March 31st consolidated financial statements, adjusted for any contributions paid, distributions received from the investment, and significant fund transactions or market events during the reporting period. We recorded a cumulative adjustment to opening retained earnings on January 1, 2018 for the difference between fair value and cost for these fund investments. The estimated fair value and carrying value of these venture capital and private equity fund investments was $205.7 million as of March 31, 2018. As of December 31, 2017, these investments were carried at cost and had a carrying value of $98.5 million.

Effective January 1, 2018, we adopted ASU 2016-01 Recognition and Measurement of Financial Assets and Financial Liabilities which eliminated the concept of cost method accounting. On a prospective basis we will report our other investments in the line item "Other investments without a readily determinable fair value". These investments include direct equity investments in private companies. The carrying value is based on the price at which the investment was acquired plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments. We consider a range of factors when adjusting the fair value of these investments, including, but not limited to, the term and nature of the investment, local market conditions, values for comparable securities, current and projected operating performance, exit strategies, financing transactions subsequent to the acquisition of the investment and a discount for certain investments that have lock-up restrictions or other features that indicate a discount to fair value is warranted. For further details on the carrying value of these investments refer to Note 6—“Investment Securities" of the “Notes to Interim Consolidated Financial Statements (unaudited)” under Part I, Item 1 of this report.

(4)Investments classified as other equity securities (fair value accounting) represent shares held in public companies as a result of exercising public equity warrant assets and direct public equity investments in public companies held by our consolidated funds. Effective January 1, 2018 we adopted ASU 2016-01 Recognition and Measurement of Financial Assets and Financial Liabilities which requires equity securities to be measured at fair value with changes in the fair value recognized through net income. Prior to January 1, 2018 we reported equity securities in public companies that we held as a result of exercising public equity warrant assets in available-for-sale securities. On a prospective basis, these equity securities will be reported in non-marketable and other securities.

Volcker Rule
On June 6, 2017, we received notice that the Board of Governors of the Federal Reserve System approved the Company’s application for an extension of the permitted conformance period for the Company’s investments in “illiquid” covered funds. The approval extends the deadline by which the Company must sell, divest, restructure or otherwise conform such investments to the provisions of the Volcker Rule until the earlier of (i) July 21, 2022, or (ii) the date by which each fund matures by its terms or is otherwise conformed to the Volcker Rule.
As implemented under the Dodd-Frank Wall Street Reform and Consumer Protection Act, the Volcker Rule prohibits, subject to certain exceptions, a banking entity, such as the Company, from sponsoring or investing in covered funds, defined to include many venture capital and private equity funds.  As noted above, the Company currently maintains certain investments deemed to be prohibited investments in “illiquid” covered funds, which are now covered under the approved extension. As of September 30, 2017,March 31, 2018, such prohibited investments had an estimated aggregate carrying value of approximately $147 million (and an aggregateand fair value of approximately $249 million).$250 million. (For more information about the Volcker Rule, see “Business—Supervision and Regulation” under Part 1, Item 1 of Part 1 of our 20162017 Form 10-K.)

At December 31, 2016,2017, gross loans equal to or greater than $20 million to any single client (individually or in the aggregate) totaled $8.9$10.5 billion, or 44.445.3 percent of our portfolio. These loans represented 233277 clients, and of these loans, $79.7$52.1 million were on nonaccrual status as of December 31, 2016.2017.
The credit profile of our loan portfolio clients varies based on the nature of the lending we do for different market segments. Our three main market segments include (i) technology (software/internet and hardware) and life science/healthcare, (ii) private equity/venture capital, and (iii) SVB Private Bank.
(i) Technology and Life Science/Healthcare
Our technology and life science/healthcare loan portfolios include loans to clients at all stages of their life cycles and represent the largest segments of our loan portfolio. The primary underwriting method for our technology and life science/healthcare portfolios are classified as investor dependent, balance sheet dependent or cash flow dependent.
Investor dependent loans represent a relatively small percentage of our overall portfolio at 11 percent of total gross loans at both September 30, 2017March 31, 2018 and December 31, 2016.2017. These loans are made to companies in both our Accelerator (early-stage) and Growth practices. Investor dependent loans typically have modest or negative cash flows and no established record of profitable operations. Repayment of these loans may be dependent upon receipt by borrowers of additional equity financing from venture capital firms or others, or in some cases, a successful sale to a third party or an IPO. Venture capital firms may provide financing selectively, at reduced amounts, or on less favorable terms, which may have an adverse effect on our borrowers' ability to repay their loans to us. When repayment is dependent upon the next round of venture investment and there is an indication that further investment is unlikely or will not occur, it is often likely that the company would need to be sold to repay debt in full. If reasonable efforts have not yielded a likely buyer willing to repay all debt at the close of the sale or on commercially viable terms, the account will most likely be deemed to be impaired.
Balance sheet dependent loans, which includes asset-based loans, represented 109 percent of total gross loans at September 30, 2017March 31, 2018 compared to 1310 percent at December 31, 2016.2017. Balance sheet dependent loans are structured to require constant current asset coverage (i.e. cash, cash equivalents, accounts receivable and, to a much lesser extent, inventory) in an amount that exceeds the outstanding debt. These loans are generally made to companies in our Growth and Corporate Finance practices. Our asset-based lending, which includes working capital lines and accounts receivable financing, both represented threetwo percent of total gross loans as of September 30, 2017March 31, 2018, and five percent and twoboth represented three percent of total gross loans at December 31, 2016, respectively.2017. The repayment of these arrangements is dependent on the financial condition, and payment ability, of third parties with whom our clients do business.
Cash flow dependent loans, which include sponsored buyout lending, represent our largest source of repayment within our technology and life science/healthcare loan portfolios at approximatelyrepresented 19 percent of total gross loans at September 30, 2017, compared to 22 percent of total gross loans atboth March 31, 2018 and December 31, 2016.2017. Cash flow dependent loans require the borrower

to maintain cash flow from operations that is sufficient to service all debt. Borrowers must demonstrate normalized cash flow in excess of all fixed

charges associated with operating the business. Sponsored buyout loans represented 10nine percent of total gross loans at September 30, 2017, compared to 11 percent of total gross loans atboth March 31, 2018 and December 31, 2016.2017. These loans are typically used to assist a select group of experienced private equity sponsors with the acquisition of businesses, are larger in size, and repayment is generally dependent upon the cash flows of the acquired company. The acquired companies are typically established, later-stage businesses of scale and characterized by reasonable levels of leverage and loan structures that include meaningful financial covenants. The sponsor's equity contribution is often 50 percent or more of the acquisition price.

(ii) Private Equity/Venture Capital
We also provide financial services to clients in the private equity/venture capital community. At September 30, 2017,March 31, 2018, our lending to private equity/venture capital firms and funds represented 4345 percent of total gross loans, compared to 3943 percent of total gross loans at December 31, 2016.2017. The vast majority of this portfolio consists of capital call lines of credit, the repayment of which is dependent on the payment of capital calls by the underlying limited partner investors in the funds managed by these firms. These facilities are generally governed by meaningful financial covenants oriented towards ensuring that the funds' remaining callable capital is sufficient to repay the loan, and larger commitments (typically provided to larger private equity funds) are often secured by an assignment of the general partner's right to call capital from the fund's limited partner investors.

(iii) SVB Private Bank
Our SVB Private Bank clients are primarily private equity/venture capital professionals and executive leaders of the innovation companies they support. Our lending to SVB Private Bank clients represented 11 percent of total gross loans at both September 30, 2017March 31, 2018 and December 31, 2016.2017. Many of these clients have mortgages, which represented 8587 percent of this portfolio at September 30, 2017;March 31, 2018; the balance of this portfolio consisted of home equity lines of credit, restricted stock purchase loans, capital call lines of credit, and other secured and unsecured lending.

State Concentrations
Approximately 3130 percent and 1110 percent of our outstanding total gross loan balances at both September 30, 2017 and Decemberas of March 31, 20162018 were to borrowers based in California and New York.York, respectively, compared to 31 percent and 10 percent as of December 31, 2017. Other than California and New York, there are no states with gross loan balances greater than 10 percent. In October 2017, wildfires impacted regions of Northern California where some of our premium wine clients are located. As of September 30, 2017, our total loans outstanding for our wine portfolio was $925 million (4% of total loan portfolio) with loans outstanding to clients in the impacted regions of approximately $700 million. We do not currently believe there will be a material effect on the credit quality of our wine portfolio in the near term; however, we will continue to monitor this segment of our portfolio closely.

See generally “Risk Factors–Credit Risks” set forth under Part I, Item 1A Part I in our 20162017 Form 10-K.

Credit Quality Indicators
As of September 30, 2017March 31, 2018 and December 31, 2016,2017, our total criticized loans and impaired loans both represented four percent and six percent of our total gross loans, respectively.loans. Criticized and impaired loans to early-stage clients represented 1720 percent and 22 percent of our total criticized and impaired loan balances at both September 30, 2017March 31, 2018 and December 31, 2016.2017, respectively. Loans to early-stage clients represent a relatively small percentage of our overall portfolio at six percent of total gross loans at September 30, 2017.March 31, 2018. It is common for an early-stage client’s remaining liquidity to fall temporarily below the threshold for a pass-rated credit during its capital-raising period for a new round of funding. Based on our experience, for most early-stage clients, this situation typically lasts one to two quarters and generally resolves itself with a subsequent round of venture funding, though there are exceptions, from time to time. As a result, we expect that each of our early-stage clients will reside in our criticized portfolio during a portion of their life cycle.

Credit Quality and Allowance for Loan Losses
Nonperforming assets consist of loans on nonaccrual status, loans past due 90 days or more still accruing interest, and Other Real Estate Owned (“OREO”) and other foreclosed assets. We measure all loans placed on nonaccrual status for impairment based on the fair value of the underlying collateral or the net present value of the expected cash flows. The table below sets forth certain data and ratios between nonperforming loans, nonperforming assets and the allowance for loan losses:

The decreaseincrease of one basis point was reflective primarily of the decreaseincrease in our allowance for performing loans as a percentage of total gross loans which decreasedincreased by two basis points to 0.92 percent, partially offset by an increase of one basis point in the allowanceto 0.93 percent at March 31, 2018. The one basis point increase was reflective primarily of higher qualitative reserves for nonaccrual loans as a percentage of total gross loans at September 30, 2017.our performing loan portfolio.
Our allowance for loan losses for nonaccrual loans was $43.8$44.3 million at September 30, 2017,March 31, 2018, compared to $37.3$41.8 million at December 31, 2016.2017. The $6.5$2.5 million increase in the allowance for nonaccrual loans included $48.0$11.5 million of new nonaccrual loan reserves, partially offset by $41.4$9.0 million of charge-offs and reserve releases. New nonaccrual loan reserves of $48.0$11.5 million were mostly attributable to our software/internet loan portfolio.

Foreign Exchange Spot Contract Assets

Foreign exchange spot contract assets represent unsettled client trades at the end of the period. The increase of $94.2$47.0 million was due primarily to an overall increase in activity at period-end as compared to December 31, 2016.2017.
Accrued Interest Receivable
The increase of $10.5 million in accrued interest was primarily reflective of the strong growth of our loans. Period-end loan balances were $24.6 billion, an increase of $1.5 billion, or 6.4 percent, as compared to March 31, 2017.
Other
Other includes various asset amounts for other operational transactions. The increase of $47.4 million was primarily due to a $45.2 million increase in warrant receivables related to the sale of our Roku shares during the three months ended March 31, 2018.

Equity Warrant Assets
In connection with negotiating credit facilities and certain other services, we often obtain rights to acquire stock in the form of equity warrant assets in primarily private, venture-backed companies in the technology and life science/healthcare industries. At September 30, 2017,March 31, 2018, we held warrants in 1,8421,929 companies, compared to 1,7391,868 companies at December 31, 2016.2017. Warrants in 1613 companies each had values greater than $1.0 million and collectively represented $51.7$31.0 million, or 36.522.9 percent, of the fair value of the total warrant portfolio at September 30, 2017.March 31, 2018. The change in fair value of equity warrant assets is recorded in gains on equity warrant assets, net, in noninterest income, a component of consolidated net income. The following table provides a summary of transactions and valuation changes for equity warrant assets for the three and nine months ended September 30, 2017March 31, 2018 and 2016:2017:

Foreign Exchange Forward and Foreign Currency Option Contracts
We enter into foreign exchange forward contracts and foreign currency option contracts with clients involved in foreign activities, either as the purchaser or seller, depending upon the clients’ needs. For each forward or option contract entered into with our clients, we enter into an opposite way forward or option contract with a correspondent bank, which mitigates the risk of fluctuations in currency rates. We also enter into forward contracts with correspondent banks to economically reduce our foreign exchange exposure related to certain foreign currency denominated instruments. Net gains and losses on the revaluation of foreign currency denominated instruments are recorded in the line item “Other” as part of noninterest income, a component of consolidated net income. We have not experienced nonperformance by any of our counterparties and therefore have not incurred any related losses. Further, we anticipate performance by all counterparties. Our net exposure for foreign exchange forward and foreign currency option contracts was $4.2 million at September 30, 2017 was $1.1 millionMarch 31, 2018 and our net exposurezero at December 31, 2016 was $0.8 million.2017. For additional information on our foreign exchange forward contracts and foreign currency option contracts, see Note 9—“Derivative Financial Instruments” of the “Notes to Interim Consolidated Financial Statements (unaudited)” under Part I, Item 1 of this report.

Client Interest Rate Derivatives

We sell interest rate contracts to clients who wish to mitigate their interest rate exposure. We economically reduce the interest rate risk from this business by entering into opposite way contracts with correspondent banks. Our net exposure for client interest rate derivative contracts was zero at September 30, 2017both March 31, 2018 and our net exposure at December 31, 2016 was $0.3 million.2017. For additional information on

Foreign Exchange Spot Contract Liabilities
Foreign exchange spot contract liabilities represent unsettled client trades at the end of the period. The increase of $181.2$181.7 million was due primarily to increased client trade activity at period-end as compared to December 31, 2016.2017.
Accrued Compensation
Accrued compensation includes amounts for our Incentive Compensation Plan, Direct Drive Incentive Compensation Plan, Retention Program, Warrant Incentive Plan, ESOP and other compensation arrangements. The decrease of $106.4 million was primarily the result of the payout of our 2017 incentive compensation plans during the first quarter of 2018, partially offset by higher accruals for the three months ended March 31, 2018 primarily due to the increase in the number of average FTEs for the first quarter of 2018.

Other
Other includes various accrued liability amounts for other operational transactions. The increase of $163.3$209.4 million was reflective primarily of a $145.3$98.5 million increase in unsettled investment securities purchases, a $62.3 million increase in current taxes payable and a $55.8 million increase in FX trade liability at September 30, 2017March 31, 2018 as compared to December 31, 2016.2017.
Noncontrolling Interests
Noncontrolling interests totaled $137.5$144.3 million and $134.5$139.6 million at September 30, 2017March 31, 2018 and December 31, 2016,2017, respectively. The $3.0$4.7 million increase was due primarily to income attributable to noncontrolling interests of $21.2$13.1 million, partially offset by net distributions of $18.2$8.4 million to limited partners from various managed funds of funds for the ninethree months ended September 30, 2017.March 31, 2018.

Financial assets valued using Level 3 measurements consist of our non-marketable investment securities in shares of private company stock and equity warrant assets (rights to shares of private and public company capital stock). The valuation methodologies of our non-marketable securities carried under fair value accounting and equity warrant assets involve a significant degree of management judgment. Refer to Note 14—15—“Fair Value of Financial Instruments” of the “Notes to Interim Consolidated Financial Statements (unaudited)” under Part I, Item 1 of this report for a summary of the valuation techniques and significant inputs used for each class of Level 3 assets.
The inherent uncertainty in the process of valuing securities for which a ready market does not exist may cause our estimated values of these securities to differ significantly from the values that would have been derived had a ready market for the securities existed, and those differences could be material. The timing and amount of changes in fair value, if any, of these financial instruments depend upon factors beyond our control, including the performance of the underlying companies, fluctuations in the market prices of the preferred or common stock of the underlying companies, general volatility and interest rate market factors, and legal and contractual restrictions. The timing and amount of actual net proceeds, if any, from the disposition of these financial instruments depend upon factors beyond our control, including investor demand for IPOs, levels of M&A activity, legal and contractual restrictions on our ability to sell, and the perceived and actual performance of portfolio companies. All of these factors are difficult to predict and there can be no assurances that we will realize the full value of these securities, which could result in significant losses. See “Risk Factors” set forth in our 20162017 Form 10-K.
During the three and nine months ended September 30, 2017,March 31, 2018, the Level 3 assets that are measured at fair value on a recurring basis experienced net realized and unrealized gains of $24.4 million and $41.4$18.7 million primarily due to realized and unrealized net gains on equity warrant assets due primarily to M&A and IPO activity. During the three and nine months ended September 30, 2016,March 31, 2017, the Level 3 assets that are measured at fair value on a recurring basis experienced net realized and unrealized gains of $21.1 million and $33.1$6.6 million primarily due to valuation increases from our public and private company warrant portfolios and net gains realized on exercised warrant assets due to IPO and M&A activity.

Capital Resources
We maintain an adequate capital base to support anticipated asset growth, operating needs and credit and other business risks, and to provide for SVB Financial and the Bank to be in compliance with all regulatory capital guidelines. Our primary sources of new capital include retained earnings and proceeds from the sale and issuance of our capital stock or other securities. In consultation with the Finance Committee of our Board of Directors, management engages in regular capital planning processes in an effort to optimize the use of capital available to us and to appropriately plan for our future capital needs. The capital plan considers capital needs for the foreseeable future and allocates capital to both existing and future business activities. Expected future use or activities for which capital may be set aside include balance sheet growth and associated relative increases in market or credit exposure, investment activity, potential product and business expansions, acquisitions and strategic or infrastructure investments. In addition, we conduct capital stress tests as part of our annual capital planning process. The capital stress tests allow us to assess the impact of adverse changes in the economy and interest rates on our capital adequacy position.
SVBFG Stockholders’ Equity
SVBFG stockholders’ equity totaled $4.1$4.4 billion at September 30, 2017,March 31, 2018, an increase of $417.3$236 million, or 11.55.6 percent, compared to $3.6$4.2 billion at December 31, 2016.2017. This increase was due primarily to net income of $373.3$195 million for the ninethree months ended September 30, 2017March 31, 2018 and ana net increase to equity of $68.8 million related to the adoption of new accounting guidance partially offset by a decrease in additional paid-in capitalthe fair value of $51.8our AFS securities portfolio of $42.1 million, attributable primarily to amortizationnet of share-based compensation expense and common stock issued under employee benefit plans.tax, driven by increases in period-end market interest rates.
Funds generated through retained earnings are a significant source of capital and liquidity and are expected to continue to be so in the future.
Capital Ratios
Both SVB Financial and the Bank are subject to various regulatory capital requirements administered by state and federal banking agencies.
Regulatory capital ratios for SVB Financial and the Bank exceeded minimum federal regulatory guidelines for a well-capitalized depository institution as of September 30, 2017March 31, 2018 and December 31, 2016.2017.

Capital ratios (CET 1, tier 1, and total risk-based capital and tier 1 leverage)capital) for SVB Financial increased as of September 30, 2017,March 31, 2018, compared to the same ratios as of December 31, 2016. The changes were driven by an2017 primarily as a result of the adoption of new accounting guidance that resulted in a net increase in capital during the nine months ended September 30, 2017, primarily from net income. Anof $68.8 million. This increase in additional paid-in capital from share-based compensation expense duringin addition to net income of $195.0 million, more than offset the nine months ended September 30, 2017 also resulted in a benefit to the capital ratios. The

increases in capital were partially offset by an increase in risk-weighted assets dueprimarily attributable to period-endour robust loan growth and higher investment and cash balances driven by increases in deposits.for the first quarter of 2018. Overall, excluding

the impact of the adoption of new accounting guidance, SVB Financial Group's risk-based capital and tier 1 leverage) for the Bankratios would have decreased as of September 30, 2017,March 31, 2018, compared to the same ratios as of December 31, 2016.2017.
Capital ratios (CET 1, tier 1, and total risk-based capital) for the Bank decreased as of March 31, 2018, compared to the same ratios as of December 31, 2017. The decrease in the Bank's capital ratios reflected $60.0$25.0 million of cash dividends paid by the Bank to our bank holding company, SVB Financial, during the ninethree months ended September 30, 2017.March 31, 2018.
Both SVB Financial and the Bank's tier 1 leverage ratios increased as of March 31, 2018, compared to December 31, 2017, due to proportionally higher capital from net income to average assets growth during the first quarter of 2018. All of our reported capital ratios remain above the levels considered to be “well capitalized” under applicable banking regulations.
The tangible common equity to tangible assets ratio and the tangible common equity to risk-weighted assets ratios are not required by GAAP or applicable bank regulatory requirements. However, we believe these ratios provide meaningful supplemental information regarding our capital levels. Our management uses, and believes that investors benefit from referring to, these ratios in evaluating the adequacy of the Company’s capital levels; however, these financial measures should be considered in addition to, not as a substitute for or preferable to, comparable financial measures prepared in accordance with GAAP. These ratios are calculated by dividing total SVBFG stockholders' equity, by total period-end assets and risk-weighted assets, after reducing both amounts by acquired intangibles, if any. The manner in which this ratio is calculated varies among companies. Accordingly, our ratio is not necessarily comparable to similar measures of other companies.

The growth in period-end risk-weighted assets was primarily due to period-end loan growth and higher investment and cash balances driven by increases in deposits. The decrease for the Bank was a result of $60.0 million in cash dividends paid by the Bank to our bank holding company, SVB Financial, during the nine months ended September 30, 2017. See “SVBFG Stockholders’ Equity” above for further details on changes to the individual components of our equity balance.
Off-Balance Sheet Arrangements
In the normal course of business, we use financial instruments with off-balance sheet risk to meet the financing needs of our customers. These financial instruments include commitments to extend credit, commercial and standby letters of credit and commitments to invest in venture capital and private equity fund investments. These instruments involve, to varying degrees, elements of credit risk. Credit risk is defined as the possibility of sustaining a loss because other parties to the financial instrument fail to perform in accordance with the terms of the contract. For details of our commitments to extend credit, and commercial and standby letters of credit, please refer to Note 12—13—“Off-Balance Sheet Arrangements, Guarantees and Other Commitments” of the “Notes to Interim Consolidated Financial Statements (unaudited)” under Part I, Item 1 of this report.
Commitments to Invest in Venture Capital and Private Equity Funds
Subject to applicable regulatory requirements, including the Volcker Rule, we make investments. We make commitments to invest in venture capital and private equity funds, which in turn make investments generally in, or in some cases make loans to, privately-held companies. Commitments to invest in these funds are generally made for a 10-year period from the inception of the fund. Although the limited partnership agreements governing these investments typically do not restrict the general partners from calling 100% of committed capital in one year, it is customary for these funds to generally call most of the capital

commitments over 5 to 7 years; however in certain cases, the funds may not call 100% of committed capital over the life of the

fund. The actual timing of future cash requirements to fund these commitments is generally dependent upon the investment cycle, overall market conditions, and the nature and type of industry in which the privately held companies operate.
For further details on our commitments to invest in venture capital and private equity funds, refer to Note 12—13—“Off-Balance Sheet Arrangements, Guarantees and Other Commitments” of the “Notes to Interim Consolidated Financial Statements (unaudited)” under Part I, Item 1 of this report.
Liquidity
The objective of liquidity management is to ensure that funds are available in a timely manner to meet our financial obligations, including, as necessary, paying creditors, meeting depositors’ needs, accommodating loan demand and growth, funding investments, repurchasing securities and other operating or capital needs, without incurring undue cost or risk, or causing a disruption to normal operating conditions.
We regularly assess the amount and likelihood of projected funding requirements through a review of factors such as historical deposit volatility and funding patterns, present and forecasted market and economic conditions, individual client funding needs, and existing and planned business activities. Our Asset/Liability Committee (“ALCO”), which is a management committee, provides oversight to the liquidity management process and recommends policy guidelines for the approval of the Finance Committee of our Board of Directors, and courses of action to address our actual and projected liquidity needs. Additionally, we routinely conduct liquidity stress testing as part of our liquidity management practices.
Our deposit base is, and historically has been, our primary source of liquidity. Our deposit levels and cost of deposits may fluctuate from time to time due to a variety of factors, including market conditions, prevailing interest rates, changes in client deposit behaviors, availability of insurance protection, and our offering of deposit products. We may also offer more investment alternatives for our off-balance sheet products which may impact deposit levels. At September 30, 2017,March 31, 2018, our period-end total deposit balances were $44.8$45.9 billion, compared to $39.0$44.3 billion at December 31, 2016.2017.
Our liquidity requirements can also be met through the use of our portfolio of liquid assets. Our definition of liquid assets includes cash and cash equivalents in excess of the minimum levels necessary to carry out normal business operations, short-term investment securities maturing within one year, available-for-sale securities eligible and available for financing or pledging purposes with a maturity in excess of one year and anticipated near-term cash flows from investments.
We have certain facilities in place to enable us to access short-term borrowings on a secured (using high-quality fixed incomeloans and AFS securities as collateral) and an unsecured basis. These include repurchase agreements and uncommitted federal funds lines with various financial institutions. We also pledge securities to the FHLB of San Francisco and the discount window at the Federal Reserve Bank. The fair value of collateral pledged to the FHLB of San Francisco (comprised primarily of loans and U.S. Treasury securities) at September 30, 2017March 31, 2018 totaled $1.9$3.8 billion, all of which $3.1 billion was unused and available to support additional borrowings. The fair value of collateral pledged at the discount window of the Federal Reserve BankFRB (comprised primarily of U.S. Treasury securities and U.S. agency debentures) at September 30, 2017March 31, 2018 totaled $0.7$1.0 billion, all of which was unused and available to support additional borrowings.
On a stand-alone basis, SVB Financial’s primary liquidity channels include cash flow from investments and interest in financial assets (including equity warrants) held by SVB Financial or its operating subsidiaries other than the Bank; to the extent declared, dividends from the Bank;Bank, its portfolio of liquid assets, and its ability to the extent needed, capital market transactions offeringraise debt and equity instruments in the public and private markets.capital. Consistent with recent prior quarters, the Bank has paid a quarterly dividend to SVB Financial. For the three and nine months ended September 30, 2017,March 31, 2018, the dividend amount paid was $20 million and $60 million, respectively.
$25.0 million. The ability of the Bank to pay dividends is subject to certain regulations described in “Business—Supervision and Regulation—Restriction on Dividends” under Part I, Item 1 of our 20162017 Form 10-K.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Interest Rate Risk Management
Market risk is defined as the risk of adverse fluctuations in the market value of financial instruments due to changes in market interest rates. Interest rate risk is our primary market risk and can result from timing and volume differences in the repricing of our rate-sensitive assets and liabilities, widening or tightening of credit spreads, changes in the general level of market interest rates and changes in the shape and level of the benchmark LIBOR/SWAP yield curve. Additionally, changes in interest rates can influence the rate of principal prepayments on mortgage securities, which affects the rate of amortization of purchase premiums and discounts. Other market risks include foreign currency exchange risk, equity price risk, including the effect of competition on product pricing. While all of these risks are important considerations, all are inherently difficult to predict, and it is equally difficult to assess the impact of each on the overall simulation results. Consequently, simulations used to analyze sensitivity of net interest income to interest rate risk will differ from actual results due to differences in the timing, frequency, and magnitude of changes in market rates, the impact of competition, fluctuating business conditions, and the impact of strategies taken by management to mitigate these risks.
Interest rate risk is managed by our ALCO. ALCO reviews the sensitivity of the market valuation on earning assets and funding liabilities and 12-month forward looking net interest income from changes in interest rates, structural changes in investment and funding portfolios, loan and deposit activity and current market conditions. Adherence with relevant metrics included in our Interest Rate Risk Policy, which is approved by the Finance Committee of our Board of Directors, is monitored on an ongoing basis.
Management of interest rate risk is carried out primarily through strategies involving our fixed income securities portfolio, available funding channels and capital market activities. In addition, our policies permit the use of off-balance sheet derivatives to assist in managing interest rate risk.
We utilize a simulation model to perform sensitivity analysis on the economic value of our equity and our net interest income under a variety of interest rate scenarios, balance sheet forecasts and business strategies. The simulation model provides a dynamic assessment of interest rate sensitivity embedded within our balance sheet which measures the potential variability in economic value and net interest income relating solely to changes in market interest rates over time. We review our interest rate risk position and sensitivity to market rates on a quarterly basis at a minimum.    

Model Simulation and Sensitivity Analysis
A specific application of our simulation model involves measurement of the impact of changes in market interest rates on our economic value of equity (“EVE”). EVE is defined as the market value of assets, less the market value of liabilities, adjusted for any off-balance sheet items, if any. Another application of the simulation model measures the impact of changes in market interest rates on our net interest income (“NII”) assuming a static balance sheet as of the period-end reporting date. Meaning, the size and composition of earning assets and funding liabilities are held constant over the simulation horizon. Simulated cash flows during the scenario horizon are assumed to be replaced as they occur, which restores the balance sheet to its original size and composition. More specifically, with respect to earning assets, loan maturities, principal maturities, paydowns and calls on investments are added back as replacement balances as they occur during the simulation horizon. Yield and spread assumptions on cash and investment balances reflect current market rates. Yield and spread assumptions on loans reflect recent market impacts on product pricing. Similarly, we make certain deposit decay rate assumptions on demand deposits and interest bearing deposits, which are replenished to hold the level and mix of funding liabilities constant. Changes in market interest rates that affect us are principally short-term interest rates and include the following benchmark indexes: (i) National and SVB Prime rates, (ii) 1-month and 3-month LIBOR, and (iii) the Federal Funds target rate. Changes in these short-term rates impact interest earned on our variable rate loans, variable rate investment securities and balances held as cash and cash equivalents. Additionally, simulated changes in deposit pricing relative to changes in market rates, commonly referred to as deposit beta, generally follow overall changes in short-term interest rates, although actual changes may lag in terms of timing and magnitude. Overall, the assumed weighted deposit beta on interest bearing deposits is approximately 35.0 percent, which means deposit repricing is assumed to be approximately 35.0 percent of a given change in short-term interest rates. This repricing is reflected as a change in interest expense on interest bearing deposit balances.
For the three months ended September 30, 2017, our results include two key modeling assumption changes relating to our non-maturity deposits and prepayments on outstanding commercial loans. The impact was seen primarily in our EVE sensitivity profile and, to a lesser degree, on our NII sensitivity.
For non-maturity deposits, the assumed deposit decay rate is greater in current modeled results compared to assumptions used in prior periods. The impact of the change in assumptions in all rate simulations resulted in greater market value sensitivity of deposits and greater EVE sensitivity overall. Prepayment rate assumptions on commercial loans are also greater in current modeled results compared to assumptions used in prior periods. The impact of the change in assumptions resulted in lower market value sensitivity on commercial loans but the impact on overall EVE sensitivity was minimal in comparison to the overall changes in EVE sensitivity.
The following table presents our EVE and NII sensitivity exposure related to an instantaneous and sustained parallel shift in market interest rates of 100 and 200 basis points at September 30, 2017March 31, 2018 and at December 31, 2016 (as revised based on the assumptions noted above):2017:

Economic Value of Equity
The estimated EVE in the preceding table is based on a combination of valuation methodologies including a discounted cash flow analysis and a multi-path lattice based valuation. Both methodologies use publicly available market interest rates to

determine discounting factors on projected cash flows. The model simulations and calculations are highly assumption-dependent and will change regularly as the composition of earning assets and funding liabilities change (including the impact of changes in the value of interest rate derivatives, if any), as interest rate environments evolve, and as we change our assumptions in response to relevant market conditions, competition or business circumstances. These calculations do not reflect forecast changes in our balance sheet or changes we may make to reduce our EVE exposure as a part of our overall interest rate risk management strategy.
As with any method of measuring interest rate risk, certain limitations are inherent in the method of analysis presented in the preceding table. We are exposed to yield curve risk, prepayment risk, basis risk, and yield spread compression, which cannot be fully modeled and expressed using the above methodology. Accordingly, the results in the preceding table should not be relied upon as a precise indicator of actual results in the event of changing market interest rates. Additionally, the resulting EVE and NII estimates are not intended to represent, and should not be construed to represent our estimate of the underlying value of equity or forecast of NII.

Our base case EVE as of September 30, 2017March 31, 2018 increased from December 31, 20162017 by $0.8 billion primarily due to$546 million, driven by changes in balance sheet mix changescomposition as well as the assumption model changes discussed above. As of September 30, 2017, period-end loans, net of unearned income increased $2.3 billionrising interest rates. At March 31, 2018, as compared to December 31, 2016. Comparing the same periods, period-end2017, total loan balances increased by $1.5 billion primarily in Prime-based variable rate loans. Total fixed income investment securities increased $2.6 billion and period-end cash and cash equivalentsalso increased by $1.0$0.8 billion driven primarilydue to purchases of fixed rate long maturity instruments such as pass-through mortgage-backed securities and municipal debt securities combined with run-off of shorter maturity U.S. Treasury securities. Additionally, total deposits increased by an increase$1.6 billion.
Marginally higher LIBOR/swap rates in deposits balances of $5.8 billion.
Higher short-term LIBOR rates as of September 30, 2017, with marginally lower long-term rates, contributedthe 3- to 24-month tenors continue to drive a flattening of therelatively flat yield curve compared to December 31, 2016. Changes in nominal2017. These higher rates and acontributed $349 million of the $546 million total change in the shape of the yield curve resulted inbase EVE, mainly impacting the market value of deposits decreasing proportionally higher than assets. However, as noted above, non-maturity deposit modeling assumption changes weredeposits. Increased holdings of 30-year pass-through mortgage-backed securities and municipal securities resulted in a $90 million decrease in EVE sensitivity in the primary driver of a higher base case EVE as of September 30, 2017.+100 bps rate shock scenario. Compared to December 31, 2016, proportional growth in loans, investments, and deposits did not significantly impact2017, EVE sensitivity measures in the +100 bps-100 and +200-200 bps rate shock scenarios as of September 30, 2017. The changeincreased $252 million and $421 million, respectively. This represents a decrease in EVEthe sensitivity, can be attributed primarily due to changes in the non-maturity assumptions changes asinvestment portfolio composition described above.
12-Month Net Interest Income Simulation
Our simulatedestimated 12-month base case NII forecast at September 30, 2017March 31, 2018 increased from December 31, 20162017 by $286$163 million, primarily due to increased balances of higher yielding loans and investments as described in the impactEVE section above. As rates rise, the proportionately greater amounts of variable rate loans are expected to benefit our base 12-month NII projections. In addition, the 12-month NII simulations include repricing assumptions on our interest bearing deposit products which are applied at our discretion based on client needs and our overall funding mix. Repricing of interest bearing deposits impacts estimated interest expense. As noted previously, repricing deposit rates are generally assumed to be less than one-half of the loan prepayment assumptionsamount of simulated changes described above, higher rates on LIBOR and Prime rate based loans, higher period-end loan growth as noted above, and a higher level of earning assets at September 30, 2017.in short-term market interest rates.
NII sensitivity as of September 30, 2017at March 31, 2018 in the +100 and -100 bps rate shock scenarios is nearly symmetrical at +14.7% and -14.7%, respectively. This profile is as expected, given the composition of floating rate loans in our balance sheet. NII sensitivity in the +200 and -200 bps interest rate shock scenarios still shows asymmetry,increased $11 million and $23 million, respectively, as compared to December 31, 2017. These changes are due primarily to the changing composition of the balance sheet as noted above. Specifically, a relative increase in variable rate loans, coupled with less sensitivitya higher proportion of non-interest bearing deposit balances is expected to result in the -200 bpsan increased NII in a rising rate shock scenario due to floors on loans.environment.
The simulation model used in the above analysis incorporates embedded floors on loans in our interest rate scenarios, which prevent model benchmark rates from moving below zero percent in the down rate scenarios. The embedded floors are also a factor in the up rate scenarios to the extent a simulated increase in rates is needed before floored rates are cleared. In addition, we assume different deposit balance decay rates for each interest rate scenario based on a historical deposit study of our clients. These assumptions may change in future periods based on changes in client behavior and at management's discretion. Actual changes in our deposit pricing strategies may differ from our current model assumptions and may have an impact on our actual sensitivity overall.
ITEM 4. CONTROLS AND PROCEDURES
Disclosure Controls and Procedures
Disclosure controls and procedures are the controls and other procedures that are designed to ensure that information required to be disclosed in the reports that we file or submit under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms. Disclosure controls and procedures include, among other things, processes, controls and procedures designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.
We carried out an evaluation, under the supervision and with the participation of management, including the Chief Executive Officer and the Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of our most recently completed fiscal quarter, pursuant to Exchange Act Rule 13a-15(b). Based upon this evaluation, the Chief

Executive Officer and Chief Financial Officer have concluded that, as of the end of the period covered by this report, the Company’s disclosure controls and procedures were effective.

Changes in Internal Control
ThereExcept as set forth below, there were no changes in our internal control over financial reporting identified in management’s evaluation pursuant to Rules 13a-15(d) or 15d-15(d) of the Exchange Act during the period covered by this Quarterly Report on Form 10-Q that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
Beginning January 1, 2018, we implemented ASC 606, Revenue from Contracts with Customers.  Although the new revenue standard is expected to have an immaterial impact on our ongoing net income, we did implement changes to our processes related to revenue recognition and the control activities within them.  These included the development of new policies based on the five-step model provided in the new revenue standard, new training, ongoing contract review requirements, and gathering of information provided for disclosures.
