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 diverse set 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 months endedMarch 31, 2019 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, 2018 (“2018 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 2018 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 based on 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) the 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 February 2016, the FASB issued a new accounting standard update (ASU 2016-02, Leases (Topic 842)), which requires for all operating leases the recognition of a right-of-use ("ROU") asset and a corresponding lease liability, in the statement of financial position. For short term leases (term of 12 months or less), a lessee is permitted to make an accounting election not to recognize lease assets and lease liabilities. The lease cost will be allocated over the lease term on a straight-line basis. There were further amendments, including practical expedients, with the issuance of ASU 2018-01, “Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842” in January 2018. In July 2018 the FASB issued ASU No. 2018-11, "Leases (Topic 842): Targeted Improvements", which provides us with the option to apply the new leasing standard to all open leases as of the adoption date, on a prospective basis.

On January 1, 2019, we adopted the new accounting standard ASU 2016-02, Leases (Topic 842) and all the related amendments ("new lease standard", "ASC 842" or "ASU 2016-02") utilizing the practical expedient to apply the new lease standard as of the January 1, 2019 on a prospective basis. We also elected the "package of expedients" and elected as an accounting policy to exclude recording ROU assets and lease liabilities for leases that meet the definition of short-term leases. In addition to excluding short-term leases, we have implemented an accounting policy in which non-lease components are not separated from lease components in the measurement of ROU assets and lease liabilities for all lease contracts. The "package of expedients" allowed us to continue to account for existing leases for which the commencement date is before January 1, 2019, in accordance with the previous guidance, Leases (Topic 840), throughout the lease term, including periods after adoption of the new guidance. We recognized $146 million in ROU assets and $178 million in lease liabilities as a result of applying the new lease standard as an adjustment to our opening consolidated balance sheet on January 1, 2019. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. See Note 9—"Leases" of the “Notes to Interim Consolidated Financial Statements (unaudited)” under Part I, Item 1 of this report for additional disclosures related to our leases.

In March 2017, the FASB issued ASU No. 2017-08, Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities, which amends the amortization period for certain purchased callable debt securities held at a premium. The ASU requires entities to amortize premiums on debt securities by the first call date when the securities have fixed and determinable call dates and prices. The scope of the ASU includes all accounting premiums, such as purchase premiums and cumulative fair value hedge adjustments. The ASU does not change the accounting for discounts, which continue to be recognized over the contractual life of a security. Adoption of the ASU is on a modified retrospective basis through a cumulative effect adjustment to retained earnings as of the beginning of the year of adoption. Adoption of the ASU primarily affected our HTM portfolio of callable state and municipal debt securities. On January 1, 2019, we adopted the ASU and recognized a net reduction to retained earnings of $583 thousand.

Recent Accounting Pronouncements

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 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 2018, the FASB issued a new accounting standard update (ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement). The ASU primarily modifies certain disclosures with respect to Level 3 fair value measurements. This guidance will be effective January 1, 2020, with early adoption permitted. This guidance will not have an impact on our consolidated financial position or results of operations, and we do not expect the adoption of this standard to have a material impact on the disclosures in our Notes to the Consolidated Financial Statements.

Certain prior period amounts, primarily related to presentation changes to our financial statement line items and immaterial changes to our reportable segments, have been reclassified to conform to current period presentations.

2. Business Combination

On January 4, 2019, we completed the acquisition of Leerink Holdings LLC, the Boston-based parent company of healthcare and life science investment bank Leerink Partners LLC, now SVB Leerink Holdings LLC ("SVB Leerink"). The acquisition was previously announced on November 13, 2018. SVB Leerink is an investment bank specializing in Equity & Convertible Capital Markets, Mergers & Acquisitions, Equity Research and Sales & Trading for growth and innovation-minded healthcare and life science companies and operates as a wholly-owned subsidiary of SVB Financial.

The acquisition was accounted for as a business combination and accordingly, the results of SVB Leerink's operations have been included in the Company's consolidated statement of income for the three months ended March 31, 2019 from the date of acquisition. We acquired SVB Leerink for approximately $270.9 million comprised of cash and share-based replacement award liabilities. The previously announced agreed upon purchase price of $280.0 million included $9.1 million of post-combination expenses related to share-based replacement awards. In addition, we provided a retention pool for employees of $60.0 million to be paid over five years comprised of a mix of cash and equity issued under the Company's current Equity Incentive Plan. Refer to Note 4—“Share-Based Compensation” of the “Notes to Interim Consolidated Financial Statements (unaudited)” under Part I, Item 1 of this report for more information. The following table summarizes the allocation of the purchase price to the net assets of SVB Leerink as of January 4, 2019:

(Dollars in thousands)	January 4, 2019
Cash paid	$	263,310
Replacement award liabilities (1)	7,629
Total purchase consideration	$	270,939
Fair value of net assets acquired	135,749
Goodwill	$	135,190

(1) The replacement award liabilities recognized as part of the total purchase consideration and the post-combination expenses of $9.1 million related to share-based replacement awards will be paid out in cash in accordance with SVB Leerink's original grant date vesting schedules.

The following table summarizes the estimated fair value of assets acquired and liabilities assumed at the date of acquisition:

(Dollars in thousands)	January 4, 2019
Assets acquired:
Cash and cash equivalents	$	163,273
Investment securities	32,986
Accounts receivable	37,538

Other liabilities	33,131
Noncontrolling interests	5,256
Total liabilities assumed	194,076
Fair value of net assets acquired	$	135,749

The Company recognized provisional identifiable intangible assets of $60.9 million and goodwill of $135.2 million as a result of the acquisition. The goodwill recorded includes revenue generating synergies expected from collaboration between SVB Leerink and the Company. All reported goodwill amounts have been allocated to the SVB Leerink reporting segment and are expected to be deductible for tax purposes. The Company recorded intangible assets of $60.9 million, which are subject to amortization

over their estimated useful lives. These fair value estimates represent our best estimate of fair value at March 31, 2019. The final amounts are subject to the completion of the fiscal 2018 financial statement audit of Leerink Holdings LLC, which is expected to be completed during the second quarter of 2019. The fair value of the noncontrolling interests in Leerink Holdings LLC represents the noncontrolling ownership percentage for SVB Leerink's consolidated VIE investment securities which are measured at net asset value.

The following table summarizes the fair value and estimated useful lives of the other intangible assets at the date of acquisition:

(Dollars in thousands)	Estimated Fair Value		Weighted Average Estimated Useful Life - in Years
Other intangible assets:
Customer relationships	$	42,000	11.0
Other	18,900		9.9
Total other intangible assets	$	60,900

SVB Leerink's net income from January 4, 2019 through March 31, 2019 was approximately $5.8 million. Supplementary pro forma financial information related to the acquisition is not included because the impact to the Company's consolidated statements of income is not material. The following table represents the amount of revenue and earnings attributable to SVB Leerink that is included in our financial results from January 4, 2019 through March 31, 2019:

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 unit awards 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 months endedMarch 31, 2019 and 2018:

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 qualified affordable housing projects. A majority of these investments are through third- 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 16—“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 7—“Investment Securities" of the “Notes to Interim Consolidated Financial Statements (unaudited)” under Part I, Item 1 of this report.

As of March 31, 2019, our exposure to loss with respect to the consolidated VIEs is limited to our net assets of $227.6 million and our exposure to loss for our unconsolidated VIEs is equal to our investment in these assets of $591.3 million.

6. Cash and Cash Equivalents

The following table details our cash and cash equivalents at March 31, 2019 and December 31, 2018:

(1) As of March 31, 2019, we identified a total of 159 investments that were in unrealized loss positions, of which 151 investments totaling $5.6 billion with unrealized losses of $41.8 million have been in an impaired position for a period of time greater than 12 months. As of March 31, 2019, 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 March 31, 2019, 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.

(1) As of December 31, 2018, we identified a total of 200 investments that were in unrealized loss positions, of which 162 investments totaling $6.0 billion with unrealized losses of $78.9 million have been in an impaired position for a period of time greater than 12 months.

The following table summarizes the fixed income securities, carried at fair value, classified as available-for-sale as of March 31, 2019 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.

(1) As of March 31, 2019, we identified a total of 676 investments that were in unrealized loss positions, of which 659 investments totaling $8.9 billion with unrealized losses of $148.9 million have been in an impaired position for a period of time greater than 12 months. As of March 31, 2019, 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, which is consistent with our classification of these securities. Based on our analysis as of March 31, 2019, we deem all impairments to be temporary. Market valuations and impairment analyses on assets in the held-to-maturity securities portfolio are reviewed and monitored on a quarterly basis.

(2) The carrying value represents investments in 212 and 213 funds (primarily venture capital funds) at March 31, 2019 and December 31, 2018, 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. We 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 investments. For each fund investment, 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 31^st for our March 31^st consolidated financial statements, adjusted for any contributions paid, distributions received from the investment, and significant fund transactions or market events during the reporting period.

(3) 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 endedMarch 31, 2019:

8. 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.

The composition of loans, net of unearned income of $170 million and $173 million at March 31, 2019 and December 31, 2018, respectively, is presented in the following table:

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 full repayment of a criticized loan has been deemed improbable under the original contractual terms but full repayment remains probable overall, the loan is considered to be 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 2018 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.

The following table summarizes the credit quality indicators, broken out by portfolio segment and class of financing receivables as of March 31, 2019 and December 31, 2018:

Troubled Debt Restructurings

As of March 31, 2019, we had 19 TDRs with a total carrying value of $86.9 million where concessions have been granted to borrowers experiencing financial difficulties, in an attempt to maximize collection. There were $3.3 million of unfunded commitments available for funding to the clients associated with these TDRs as of March 31, 2019.

The following table summarizes our loans modified in TDRs, broken out by portfolio segment and class of financing receivables at March 31, 2019 and December 31, 2018:

(Dollars in thousands)	March 31, 2019		December 31, 2018

Consumer loans:
Other consumer loans	—		326
Total loans modified in TDRs during the period (1)	$	5,677	$	3,880

(1) There were $2.2 million of partial charge-offs for the three months endedMarch 31, 2019 and no partial charge-offs during the three months endedMarch 31, 2018.

During the three months endedMarch 31, 2019 and 2018, all new TDRs of $5.7 million and $3.9 million, respectively, were modified through payment deferrals granted to our 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.

33

The following table summarizes the recorded investment in loans modified in TDRs within the previous 12 months that subsequently defaulted during the three months endedMarch 31, 2019 and 2018:

	Three months ended March 31,

Life science/healthcare	5,000		—
Total TDRs modified within the previous 12 months that defaulted in the period	$	5,000	$	3,032

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 for TDRs was necessary to determine the allowance for loan losses as of March 31, 2019.

9. Leases

We have operating leases for our corporate offices, data centers and certain equipment utilized at those properties. We are obligated under a number of noncancelable operating leases for premises and equipment that expire at various dates, through 2030, and in most instances, include options to renew or extend at market rates and terms. Such leases may provide for periodic adjustments of rentals during the term of the lease based on changes in various economic indicators.

At the inception of the lease, the lease is evaluated to determine whether the lease will be accounted for as an operating or a finance lease. There were no significant assumptions or judgments required upon applying the new lease standard. Operating lease ROU assets and operating lease liabilities are included in our consolidated balance sheets. We have no leases that meet the definition of a finance lease under ASC 842 and our lessor accounting treatment for subleases is not material. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods.

Total recorded balances for the lease assets and liabilities are as follows:

(Dollars in thousands)	March 31, 2019
Assets:
Right-of-use assets - operating leases (1)	$	164,659
Liabilities:
Lease liabilities - operating leases (1)	205,167

(1) Included in these amounts are $24.4 million and $33.7 million of ROU assets and lease liabilities, respectively, attributable to the inclusion of SVB Leerink in our financial results at March 31, 2019.

34

The components of our lease cost and other information related to leases for the three months endedMarch 31, 2019 were as follows:

(Dollars in thousands)	Three months ended March 31, 2019
Operating lease cost	$	9,518
Short-term lease cost	263
Variable lease cost	846
Less: sublease income	(1,108		)
Total lease cost, net	$	9,519
Other information:
Weighted-average remaining term (in years) - operating leases	6.40
Weighted-average discount rate - operating leases (1)	3.18		%
Supplemental cash flows information:
Cash paid for operating leases	$	10,354

(1) The incremental borrowing rate used to calculate the lease liability was determined based on the facts and circumstances of the economic environment and the Company’s credit standing as of the effective date of ASC 842. Additionally, the total lease term and total lease payments were also considered in determining the rate. Based on these considerations the Company identified credit terms available under its existing credit lines which represent a collateralized borrowing rate that has varying credit terms that could be matched to total lease terms and total lease payments in ultimately determining the implied borrowing rate in each lease contract.

The following table presents our undiscounted future cash payments for our operating lease liabilities as of March 31, 2019:

(Dollars in thousands)	Operating Leases
2019 (excluding the three months ended March 31, 2019)	$	32,717
2020	40,282
2021	37,458
2022	31,902
2023	30,440
2024 and thereafter	38,577
Total future lease payments (1)	$	211,376
Less: imputed interest	(6,209		)
Total lease liabilities	$	205,167

(1) Securities sold under repurchase agreements are effectively short-term borrowings collateralized by U.S. Treasury securities.

(2) Represents cash collateral received from certain counterparties in relation to market value exposures of derivative contracts in our favor.

Interest expense related to short-term borrowings and long-term debt was $10.2 million for the three months ended March 31, 2019 and $8.4 million for the three months endedMarch 31, 2018. The weighted average interest rate associated with our short-term borrowings was 2.62 percent as of December 31, 2018. There were no overnight short-term borrowings as of March 31, 2019.

Short-term Borrowings

We have certain facilities in place to enable us to access short-term borrowings on a secured and unsecured basis. Our secured facilities include collateral pledged to the FHLB of San Francisco and the discount window at the FRB (using both fixed income securities and loans as collateral). Our unsecured facility consists of our uncommitted federal funds lines. As of March 31, 2019, collateral pledged to the FHLB of San Francisco was comprised primarily of fixed income investment securities and loans and had a carrying value of $4.5 billion, of which $4.0 billion was available to support additional borrowings. As of March 31, 2019, collateral pledged to the discount window at the FRB was comprised of fixed income investment securities and had a carrying value of $0.9 billion, all of which was unused and available to support additional borrowings. Our total unused and available borrowing capacity for our uncommitted federal funds lines totaled $1.9 billion at March 31, 2019. Our total unused and available borrowing capacity under our master repurchase agreements with various financial institutions totaled $3.3 billion at March 31, 2019.

12. 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, 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 on our variable-interest rate loan portfolio, we enter into interest rate swap contracts to hedge against future changes in interest rates by using hedging instruments to lock in future cash inflows that would otherwise be impacted by movements in the market interest rates. We designate these interest rate swap contracts as cash flow hedges that qualify for hedge accounting under ASC 815, Derivatives and Hedging ("ASC 815"), and record them in other assets and other liabilities. For qualifying cash flow hedges, changes in the fair value of the derivative are recorded in accumulated other comprehensive income and recognized in earnings as the hedged item affects earnings. Derivative amounts affecting earnings are recognized consistent with the classification of the hedged item in the line item "Loans" as part of interest income, a component of consolidated net income.

We assess hedge effectiveness under ASC 815 on a quarterly basis to ensure all hedges remain highly effective to ensure hedge accounting under ASC 815 can be applied. If the hedging relationship no longer exists or no longer qualifies as a hedge per ASC 815, any amounts remaining as gain or loss in accumulated other comprehensive income are reclassified into earnings in the line item "Loans" as part of interest income, a component of consolidated net income. As of March 31, 2019, no derivatives classified as hedges were terminated or were disqualified for hedge accounting. The maximum length of time over which the forecasted transactions are hedged is approximately five years.

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” 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” 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 2018 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.

(1) Derivative assets and liabilities are included in "Accrued interest receivable and other assets" and "Other liabilities", respectively, on our consolidated balance sheets.

(2) The amount reported for March 31, 2019 reflects rule changes implemented by two central clearing houses that require entities 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 reflect reductions of approximately $3.9 million of derivative liabilities and approximately $0.4 million of derivative assets at March 31, 2019 and December 31, 2018, respectively.

Gains on investment securities, net

Net gains on investment securities include both gains and losses from our non-marketable and other equity securities, which include public equity securities held as a result of exercised equity warrant assets, gains and losses from sales of our AFS debt securities portfolio, when applicable, and carried interest.

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, which include public equity securities held as a result of exercised equity warrant assets and 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.

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, and 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. Though infrequent, sales of debt securities in our AFS securities portfolio may result in net gains or losses and are conducted pursuant to the guidelines of our investment policy related to the management of our liquidity position and interest rate risk.

42

Gains on investment securities are recognized outside of the scope of ASC 606 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 endedMarch 31, 2019 and 2018 is as follows:

	Three months ended March 31,

Total gains on investment securities, net	$	29,028		$	9,058

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 ASC 606 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 endedMarch 31, 2019 and 2018 is as follows:

	Three months ended March 31,

Total net gains on equity warrant assets	$	21,305		$	19,191

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 ASC 606 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 endedMarch 31, 2019 and 2018 is as follows:

	Three months ended March 31,
(Dollars in thousands)	2019		2018
Foreign exchange fees by instrument type:

Forward contract commissions	2,995		2,485
Option premium fees	24		140
Total foreign exchange fees	$	38,048	$	33,827

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.

43

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.

A summary of credit card fees by instrument type for the three months endedMarch 31, 2019 and 2018 is as follows:

	Three months ended March 31,

Merchant service fees	4,534		2,906
Card service fees	1,556		1,226
Total credit card fees	$	27,483	$	21,692

Deposit service charges

Deposit service charges include fees earned from performing cash management activities and other deposit account services. Deposit services include, but are not limited to, the following: receivables services, which include merchant services, remote capture, lockbox, electronic deposit capture, and fraud control services. 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, and are presented in the "Disaggregation of revenue from contracts with customers"table below.

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 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 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. A summary of client investment fees by instrument type for the three months endedMarch 31, 2019 and 2018 is as follows:

	Three months ended March 31,

Lending related fees

Unused commitment fees, minimum finance fees and unused line fees are recognized as earned on a monthly basis. Fees that qualify for syndication treatment are recognized at the completion of the syndicated loan deal for which the fees were received. Lending related fees are recognized outside of the scope of ASC 606 as it explicitly excludes noninterest income earned from our lending-related activities. A summary of lending related fees by instrument type for the three months endedMarch 31, 2019 and 2018 is as follows:

Unused commitment fees	$	9,670	$	8,757
Other	4,267		1,978
Total lending related fees	$	13,937	$	10,735

Letters of credit and standby letters of credit fees

Commercial and standby letters of credit represent conditional commitments issued by us on behalf of a client to guarantee the performance of the client to a third party when certain specified future events have occurred. 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 ASC 606 as it explicitly excludes noninterest income earned from our lending related activities.

Investment banking revenue

The Company earns investment banking revenue from clients for providing services related to securities underwriting, private placements and advisory services on strategic matters such as mergers and acquisitions. Underwriting fees are attributable to public and private offerings of equity and debt securities and are recognized at the point in time when the offering has been deemed to be completed by the lead manager of the underwriting group. Once the offering is completed, the performance obligation has been satisfied and the Company recognizes the applicable management fee as well the underwriting fee, net of consideration payable to customers. Estimated offering expenses are presented gross in our statements of income. The Company recognizes private placement fee revenue at the point in time when the private placement is completed, which is generally when the client accepts capital from the fund raise. Advisory fees from mergers and acquisitions engagements are generally recognized at the point in time when the related transaction is completed. Expenses are deferred only to the extent they are explicitly reimbursable by the client and the related revenue is recognized at a point in time. All other deal-related expenses are expensed as incurred. The Company has determined that it acts as principal in the majority of these transactions and therefore presents expenses gross within other operating expenses.

A summary of investment banking revenue by instrument type for the three months endedMarch 31, 2019 and 2018 is as follows:

	Three months ended March 31,
(Dollars in thousands)	2019		2018
Investment banking revenue:
Underwriting fees	$	35,772	$	—
Advisory fees	12,273		—
Private placements and other	1,750		—
Total investment banking revenue	$	49,795	$	—

Commissions

Commissions include commissions received from customers for the execution of agency-based brokerage transactions in listed and over-the-counter equities. The execution of each trade order represents a distinct performance obligation and the transaction price is fixed at the point in time or trade order execution. Trade execution is satisfied at the point in time that the customer has control of the asset and as such, fees are recorded on a trade date basis. Commissions for the three months endedMarch 31, 2019 were $14.1 million.

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

45

time of a distribution event. As distribution events are not predetermined for these certain funds, management fees are considered variable and constrained under ASC 606.

Other service revenue 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.

A summary of other noninterest income by instrument type for the three months endedMarch 31, 2019 and 2018 is as follows:

	Three months ended March 31,
(Dollars in thousands)	2019			2018

The timing of revenue recognition may differ from the timing of cash settlements or invoicing to customers. We record a receivable when revenue is recognized prior to invoicing, 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, 2019 and 2018, changes in our contract assets, contract liabilities and receivables were not material. Additionally, revenues recognized during the three months ended March 31, 2019 and 2018 that were included in the corresponding contract liability balance at the beginning of the periods were not material.

15. Segment Reporting

We have four reportable segments for management reporting purposes: Global Commercial Bank, SVB Private Bank, SVB Capital and SVB Leerink. SVB Leerink is a new reportable segment and was created as a result of the acquisition of Leerink Holdings LLC effective January 4, 2019. 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 funded loans. FTP is calculated at an instrument level based on account characteristics.

47

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 tax expense 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 four 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, trade finance, and other services. We broadly serve clients within the U.S., 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.

◦ SVBWine 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 products, 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-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.

• SVB Leerink is an investment bank specializing in the equity and convertible capital markets, mergers and acquisitions, equity research and sales and trading for growth and innovation-minded healthcare and life science companies and operates as a wholly-owned subsidiary of SVB Financial. SVB Leerink provides investment banking services across all subsectors of healthcare including: biotechnology, pharmaceuticals, medical devices, diagnostic and life science tools, healthcare services and digital health. SVB Leerink focuses on two primary lines of business: (i) investment banking focused on providing companies with capital-raising services, financial advice on mergers and acquisitions, sales and trading services and equity research, and (ii) sponsorship of private investment funds.

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

(1) Global Commercial Bank’s, SVB Capital’s and SVB Leerink'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 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 $4.9 million and $5.5 million for the three months ended March 31, 2019 and 2018, 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.

(6) Included in the total average assets for SVB Leerink is goodwill of $135.2 million for the three months ended March 31, 2019 related to the acquisition effective January 4, 2019.

16. 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 March 31, 2019:

(Dollars in thousands)	SVBFG Capital Commitments		SVBFG Unfunded     Commitments		SVBFG Ownership   of each Fund (3)
CP I, LP	$	6,000	$	270	10.7	%

Total	$	478,438	$	23,046

(1) Our ownership includes direct ownership of 1.3 percent and indirect ownership interest of 3.8 percent through our investment in Strategic Investors Fund II, LP.

(2) Represents commitments to 215 funds (primarily venture capital funds) where our ownership interest is generally less than five percent of the voting interests of each such fund.

(3) We are subject to the Volcker Rule, which restricts or limits us from sponsoring or having ownership interests in “covered” funds including venture capital and private equity funds. See “Business - Supervision and Regulation” under Part 1, Item 1 of our 2018 Form 10-K.

The following table details the amounts of remaining unfunded commitments to venture capital and private equity funds by our consolidated managed funds of funds (including our interest and the noncontrolling interests) at March 31, 2019:

(Dollars in thousands)	Unfunded Commitments
Strategic Investors Fund, LP	$	1,338
Capital Preferred Return Fund, LP	1,625
Growth Partners, LP	2,516
Total	$	5,479

17. 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 and California tax returns as major tax filings. Our U.S. federal tax returns for 2015 and subsequent tax years remain open to full examination. Our California tax returns for 2015 and subsequent tax years remain open to full examination.

At March 31, 2019, our unrecognized tax benefit was $12.5 million, the recognition of which would reduce our income tax expense by $9.8 million. We do not expect that our unrecognized tax benefit will materially change in the next 12 months.

51

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 months ended March 31, 2019.

18. 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 on 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, foreign government debt 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-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

52

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.

Other equity 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. Certain sales restriction 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.

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.

Interest rate derivative and interest rate swap 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.

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:

Venture capital 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.

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

53

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.

The following table presents quantitative information about the significant unobservable inputs used for certain of our Level 3 fair value measurements at March 31, 2019 and December 31, 2018. We have not included in this table our venture capital and private equity fund investments (fair value accounting) as we use net asset value per share (as obtained from the general partners of the investments) as a practical expedient to determine fair value.

(Dollars in thousands)	Fair value		Valuation Technique	Significant Unobservable Inputs	Weighted  Average

(1) In determining the fair value of our 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.

57

(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 terminations and exercises. At March 31, 2019, the weighted average contractual remaining term was 6.1 years, compared to our estimated remaining life of 2.8 years. On a quarterly basis, a sensitivity analysis is performed on our remaining life assumption.

For the three months endedMarch 31, 2019 and 2018, 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 months endedMarch 31, 2019 and 2018 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.

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 December 31^st, for our March 31^st 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 March 31, 2019:

(Dollars in thousands)	Carrying Amount		Fair Value		Unfunded Commitments
Non-marketable securities (fair value accounting):
Venture capital and private equity fund investments (1)	$	303,418	$	303,418	$	12,540
Non-marketable securities (equity method accounting):
Venture capital and private equity fund investments (2)	148,096		148,096		12,801
Debt funds (2)	5,826		5,826		—
Other investments (2)	15,381		15,381		886
Total	$	472,721	$	472,721	$	26,227

(1) Venture capital and private equity fund investments within non-marketable securities (fair value accounting) include investments made by our managed funds of funds and one of our direct venture funds (consolidated VIEs) and investments in venture capital and private equity fund investments (unconsolidated VIEs). Collectively, these investments in venture capital and private equity funds are primarily in U.S. and global technology and life science/healthcare companies. Included in the fair value and unfunded commitments of fund investments under fair value accounting are $79.4 million and $4.1 million, respectively, attributable to noncontrolling interests. It is estimated that we will receive distributions from the fund investments overthe next 10 to 13 years, depending on the age of the funds and any potential extensions of terms of the funds.

(2) Venture capital and private equity fund investments, debt funds, and other fund investments within non-marketable securities (equity 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.

19. 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.

60

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.

20. 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 17—“Employee Compensation and Benefit Plans" under Part II, Item 8 of our 2018 Form 10-K.

Reclassifications

Certain prior period amounts, primarily related to the adoption of new accounting guidance, presentation changes to our financial statement line items and immaterial changes to our reportable segments, have been reclassified to conform to current period presentations.

Management’s Overview of First Quarter 2019 Performance

Overall, we delivered strong first quarter results in 2019, which was marked by healthy balance sheet growth, stable credit quality, robust core fee income and notable market gains. Noninterest income and noninterest expense increased primarily due to the inclusion of SVB Leerink in our financial results beginning on January 4, 2019. Our core business continued to perform well as a result of our ongoing focus on innovation companies and their investors and continued efforts to secure client relationships. We saw continued success in working with private equity/venture capital firms, our technology and life science/healthcare clients and clients in our private bank division.

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 three months endedMarch 31, 2019 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 2018 Form 10-K.

Results of Operations

Net Interest Income and Margin (Fully Taxable Equivalent Basis)

Net interest income is defined as the difference between: (i) interest earned on loans, fixed income investment in our available-for-sale and held-to-maturity securities portfolios and short-term investment securities, (ii) interest paid on funding sources. Net interest margin is defined as annualized net interest income, on a fully taxable equivalent basis, 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 21.0 percent for the three months endedMarch 31, 2019 and 2018.

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 mix 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 March 31, 2019 and 2018

Net interest income increased by $94.6 million to $515.8 million for the three months endedMarch 31, 2019, compared to $421.2 million for the comparable 2018 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 loan portfolio as well as increases from our life science/healthcare and private bank loan portfolios and rate increases subsequent to March 31, 2018. In addition, we saw an increase in interest yields 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. These increases were partially offset by an increase in interest paid on our interest-bearing deposits due to the increase in average interest-bearing deposits as well as market rate adjustments on our interest-bearing deposits.

The main factors affecting interest income for the three months endedMarch 31, 2019, compared to the comparable 2018 period are discussed below:

• Interest income for the three months endedMarch 31, 2019 increased by $120.2 million due primarily to:

◦ A $97.1 million increase in interest income on loans to $394.1 million for the three months endedMarch 31, 2019, compared to $297.1 million for the comparable 2018 period. The increase was reflective of an increase in average loan balances of $4.6 billion and an increase in the overall loan yield of 57 basis points to 5.63 percent from 5.06 percent. Gross loan yields, excluding loan interest recoveries and loan fees, increased 56 basis points to 5.10 percent from 4.54 percent, reflective primarily of the benefit of interest rate increases. Loan fee yields were relatively flat, 52 basis points for the three months endedMarch 31, 2019, compared to 51 basis points for the comparable 2018 period,

◦ A $9.6 million increase in interest income on fixed income investment securities to $140.6 million for the three months endedMarch 31, 2019, compared to $130.9 million for the comparable 2018 period. The increase was reflective of an increase in our fixed income investment securities yield of 37 basis points to 2.58 percent from 2.21 percent resulting primarily from higher reinvestment yields on maturing fixed income investments as well as sales and maturities of lower yielding securities during the quarter, and

66

◦ A $13.5 million increase in interest income from our interest-earning cash and short-term investment securities. The increase was due to the benefit from the impact of the increases in the Federal Funds target rate since March 31, 2018 as well as an increase of $1.7 billion in average interest-earning Federal Reserve cash balances.

• Interest expense for the three months endedMarch 31, 2019 increased by $25.6 milliondue primarily to:

◦ A $23.8 million increase in interest expense on deposits due primarily to an increase in interest paid on our interest-bearing money market and foreign sweep deposits as a result of market rate adjustments as well as growth in average interest-bearing deposits of $3.3 billion, and

◦ A $1.8 million increase in interest expense on borrowings primarily due to a $0.2 billion increase in our average short-term borrowings during the three months ended March 31, 2019 to fund loan growth as a result of the timing of loan funding and deposit activities.

Net Interest Margin (Fully Taxable Equivalent Basis)

Three months ended March 31, 2019 and 2018

• Our net interest margin increased by 43 basis points to 3.81 percent for the three months endedMarch 31, 2019, compared to 3.38 percent for the comparable 2018 period. The higher margin during the first quarter of 2019 was reflective primarily of the increases in the Federal Funds target rate since March 31, 2018 as well as a shift in the mix of the growth in our interest-earning assets to higher-yielding loans from our fixed income investment securities portfolio. Average loans represented 51.7 percent of average interest earnings assets for the three months ended March 31, 2019, compared to 47.1 percent for the comparable 2018 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 months endedMarch 31, 2019 and 2018:

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 months endedMarch 31, 2019 and 2018:

Three months ended March 31, 2019 and 2018

Our provision for credit losses was $28.6 million for the three months endedMarch 31, 2019, consisting of a provision for loan losses of $25.8 million and a provision for unfunded credit commitments of $2.7 million. Our provision for credit losses was $28.0 million for the three months endedMarch 31, 2018, consisting of a provision for loan losses of $27.0 million and a provision for unfunded credit commitments of $1.0 million.

The provision for loan losses of $25.8 million for the three months ended March 31, 2019 reflects primarily an increase of $27.4 million in net new specific reserves for nonaccrual loans, $4.1 million in additional reserves for period-end loan growth and $4.9 million for charge-offs not specifically reserved for, partially offset by a decrease of $8.2 million for our performing loans reserve.

The provision for unfunded credit commitments of $2.7 million was driven primarily by growth in unfunded credit commitments of $1.4 billion for three months ended March 31, 2019.

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

69

The provision for unfunded credit commitments of $1.0 million for three months endedMarch 31, 2018 was driven primarily by an increase in qualitative reserves for funded loans.

Gross loan charge-offs were $9.0 million for the three months endedMarch 31, 2019, of which $4.9 million was not specifically reserved for at December 31, 2018. Gross loan charge-offs were primarily due to $8.3 million from our software/internet loan portfolio driven by three mid-stage clients and one early-stage client.

Gross loan charge-offs were $10.6 million for the three months endedMarch 31, 2018, of which $3.4 million was not specifically reserved for at December 31, 2017. Gross loan charge-offs included $6.1 million from early-stage client loans, mostly in our software/internet and hardware portfolios of $3.2 million from a late-stage client loan in our software/internet portfolio.

See “Consolidated Financial Condition—Credit Quality and Allowance for Loan Losses” below and Note 8—“Loans, Allowance for Loan Losses and Allowance for Unfunded Credit Commitments” of the “Notes to Interim Consolidated Financial Statements (unaudited)” under Part I, Item 1 of this report for further details on our allowance for loan losses.

Noninterest Income

For the three months endedMarch 31, 2019, noninterest income was $280.4 million, compared to $155.5 million for the comparable 2018 period. For the three months endedMarch 31, 2019, non-GAAP noninterest income, net of noncontrolling interests was $277.1 million, compared to $142.5 million for the comparable 2018 period. For the three months endedMarch 31, 2019, non-GAAP core fee income including investment banking revenue and commissions was $218.1 million, compared to $115.0 million for the comparable 2018 period. For the three months endedMarch 31, 2019, non-GAAP core fee income was $154.2 million, compared to $115.0 million for the comparable 2018 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 core fee income including investment banking revenue and commissions, non-GAAP noninterest income, and 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 certain other 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, and 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, 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, lending related fees, client investment fees and letters of credit and letters of credit fees.

Core fee income including investment banking revenue and commissions is a non-GAAP measure, which represents GAAP noninterest income, but excludes certain line items where performance is typically subject to market or other conditions beyond our control.

(2) Non-GAAP core fee income represents noninterest income, but excludes certain line items where performance is typically subject to market or other conditions beyond our control, as well as our investment banking revenue and commissions, and includes foreign exchange fees, credit card fees, deposit service charges, lending related fees, client investment fees and letters of credit and standby letters of credit fees.

Gains on Investment Securities, Net

Net gains on investment securities include gains and losses from our non-marketable and other equity securities, which include public equity securities held as a result of exercised equity warrant assets, as well as gains and losses from sales of our AFS debt securities portfolio, when applicable.

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 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 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 (e.g. lock-up agreements), changes in prevailing market prices, market conditions, the actual sales or distributions of securities, and 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.

71

Our AFS 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. Though infrequent, sales of debt securities in our AFS securities portfolio may result in net gains or losses and are conducted pursuant to the guidelines of our investment policy related to the management of our liquidity position and interest rate risk.

Three months ended March 31, 2019 and 2018

For the three months endedMarch 31, 2019, we had net gains on investment securities of $29.0 million, compared to $9.1 million for the comparable 2018 period. Non-GAAP net gains on investment securities, net of noncontrolling interests, were $25.6 million for the three months endedMarch 31, 2019, compared to non-GAAP net losses, net of controlling interest of $3.8 million for the comparable 2018 period.

Non-GAAP net gains on investment securities, net of noncontrolling interests, of $25.6 million for the three months endedMarch 31, 2019 were driven by the following:

• Gains of $15.0 million from our strategic and other investments portfolio, comprised primarily of net unrealized valuation increases in public companies held in our strategic venture capital funds and an unrealized valuation increase for one company in our direct equity portfolio due to M&A activity, and

• Gains of $9.6 million from our public equity securities portfolio primarily attributable to the sale of our shares from exercised warrants in one company which were sold as soon as practicable following the lock-up period expiration, partially offset by

• Losses of $3.6 million from our AFS securities portfolio due to realized losses on the sale of approximately $1.2 billion of U.S. Treasury securities.

Gains on Equity Warrant Assets, Net

Three months ended March 31, 2019 and 2018

Net gains on equity warrant assets were $21.3 million for the three months endedMarch 31, 2019, compared to net gains of $19.2 million for the comparable 2018 period. Net gains on equity warrant assets for the three months endedMarch 31, 2019 consisted of:

72

• Net gains of $16.2 million from increases in warrant valuations compared to net gains of $10.2 million, driven by valuation increases in our private company warrant portfolio during the three months ended March 31, 2019, and

• Net gains of $5.5 million from the exercise of equity warrant assets compared to net gains of $9.9 million, primarily driven by decreased IPO activity as a result of the government shutdown during the three months ended March 31, 2019

A summary of gains on equity warrant assets, net, for the three months endedMarch 31, 2019 and 2018 is as follows:

The total fair value of our warrant portfolio was $162.2 million at March 31, 2019 and $135.7 million at March 31, 2018. Warrants in 26 companies each had fair values greater than $1.0 million and collectively represented $56.8 million, or 35.0 percent, of the fair value of the total warrant portfolio at March 31, 2019. Warrants in 13 companies each had fair values greater than $1.0 million and collectively represented $31.0 million, or 22.8 percent, of the fair value of the total warrant portfolio at March 31, 2018.

Foreign Exchange Fees

Foreign exchange fees were $38.0 million for the three months endedMarch 31, 2019, compared to $33.8 million for the comparable 2018 period. The increase in foreign exchange fees were driven primarily by increases in spot contract commissions driven by increased volume of trades for the three months endedMarch 31, 2019 compared to the 2018 period. The volume of trades for spot contracts increased 10.6 percent for the three months ended March 31, 2019, respectively, compared to the comparable 2018 period reflective primarily of our global expansion initiative and increased client engagement efforts. A summary of foreign exchange fee income by instrument type for the three months endedMarch 31, 2019 and 2018 is as follows:

Credit Card Fees

Credit card fees were $27.5 million for the three months endedMarch 31, 2019, compared to $21.7 million for the comparable 2018 period. The increase was primarily due to higher gross interchange fee income driven by an increase in transaction volume reflective of higher spending by our commercial clients and our focus on our credit card business as a key area targeted for growth. The increase in gross interchange fee income was partially offset by an increase in rebates/rewards expense for the three months endedMarch 31, 2019. A summary of credit card fees by instrument type for the three months endedMarch 31, 2019 and 2018 is as follows:

	Three months ended March 31,

Total credit card fees	$	27,483	$	21,692	26.7

Deposit Service Charges

Deposit service charges were $20.9 million for the three months endedMarch 31, 2019, compared to $17.7 million for the comparable 2018 period. The increase was reflective of higher deposit client counts, as well as higher volumes of our transaction-based fee products, during the three months endedMarch 31, 2019.

Client Investment Fees

Client investment fees were $44.5 million for the three months endedMarch 31, 2019, compared to $22.9 million for the comparable 2018 period. The increase was reflective of the large increase in average client investment funds driven by our clients’ increased utilization of our off-balance sheet sweep money market funds and products managed by SVB Asset Management. Client investment fees also benefited from improved spreads on our client investment funds due to increases in general market rates and the reintroduction of fees that had been previously waived due to the low rate environment. A summary of client investment fees by instrument type for the three months endedMarch 31, 2019 and 2018 is as follows:

Lending Related Fees

Lending related fees were $13.9 million for the three months endedMarch 31, 2019, compared to $10.7 million for the comparable 2018 period. The increase was due to an increase in unused commitment fees and higher syndication fee income. A summary of lending related fees by instrument type for the three months endedMarch 31, 2019 and 2018 is as follows:

	Three months ended March 31,
(Dollars in thousands)	2019		2018		% Change

Letters of Credit and Standby Letters of Credit Fees

Letters of credit and standby letters of credit fees were $9.4 million for the three months endedMarch 31, 2019, compared to $8.2 millionfor the comparable2018period.The increase was primarily driven by increases in deferred fee income reflective of larger letter of credit issuances.

Investment banking revenue

The Company earns investment banking revenue from clients for providing services related to securities underwriting, private placements and advisory services on strategic matters such as mergers and acquisitions. Underwriting fees are attributable to public and private offerings of equity and debt securities and are recognized at the point in time when the offering has been deemed to be completed by the lead manager of the underwriting group. Once the offering is completed, the performance obligation has been satisfied and the Company recognizes the applicable management fee as well the underwriting fee, net of consideration payable to customers. Estimated offering expenses are presented gross in our statements of income. The Company recognizes private placement fee revenue at the point in time when the private placement is completed, which is generally when the client accepts capital from the fund raise. Advisory fees from mergers and acquisitions engagements are generally recognized at the point in time when the related transaction is completed. Expenses are deferred only to the extent they are explicitly reimbursable by the client and the related revenue is recognized at a point in time. All other deal-related expenses are expensed

75

as incurred. The Company has determined that it acts as principal in the majority of these transactions and therefore presents expenses gross within other operating expenses.

A summary of investment banking revenue by instrument type for the three months endedMarch 31, 2019 and 2018 is as follows:

	Three months ended March 31,
(Dollars in thousands)	2019		2018		% Change

Commissions

Commissions include commissions received from customers for the execution of agency-based brokerage transactions in listed and over-the-counter equities. The execution of each trade order represents a distinct performance obligation and the transaction price is fixed at the point in time or trade order execution. Trade execution is satisfied at the point in time that the customer has control of the asset and as such, fees are recorded on a trade date basis. Revenue is recognized for direct payments received by the Company equity research services at a point in time when access to research has been provided, the transaction price is determined, it is probable that a significant reversal of revenue will not occur and uncertainty related to variability is resolved. Commissions for the three months endedMarch 31, 2019 were $14.1 million.

Other Noninterest Income

Total other noninterest income was $11.9 million for the three months endedMarch 31, 2019, compared to $12.3 millionfor the comparable2018period. The decrease of $0.4 million was due primarily to a decrease in other service revenue partially offset by an increase in fund management fees due to the inclusion of SVB Leerink in our financial results as of January 4, 2019.

A summary of other noninterest income for the three months endedMarch 31, 2019 and 2018 is as follows:

Non-GAAP Noninterest Expense

We use and report non-GAAP noninterest expense, non-GAAP taxable equivalent revenue and non-GAAP core 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.

Compensation and Benefits Expense

The following table provides a summary of our compensation and benefits expense for the three months endedMarch 31, 2019 and 2018:

	Three months ended March 31,
(Dollars in thousands, except employees)	2019		2018		% Change
Compensation and benefits:
Salaries and wages	$	101,200	$	73,039	38.6	%
Incentive compensation & ESOP	70,552		43,633		61.7
Other employee incentives and benefits (1)	66,309		49,134		35.0
Total compensation and benefits	$	238,061	$	165,806	43.6
Period-end full-time equivalent employees	3,250		2,512		29.4
Average full-time equivalent employees	3,228		2,498		29.2

(1) Other employee incentives and benefits includes employer payroll taxes, group health and life insurance, share-based compensation, 401(k), warrant and retention plans, agency fees and other employee-related expenses.

Compensation and benefits expense was $238.1 million for the three months endedMarch 31, 2019, compared to $165.8 million for the comparable 2018 period. The key changes in factors affecting compensation and benefits expense were as follows:

• An increase of $28.2 million in salaries and wages reflective primarily of the increase in the number of average FTE by 730 to 3,228 for the first quarter of 2019, of which 233 FTEs were attributable to the acquisition of SVB Leerink compared to the same period in 2018, as well as annual pay raises,

• An increase of $26.9 million in incentive compensation and ESOP expense reflective primarily of the inclusion of SVB Leerink in our financial results, accounting for $25.6 million of the increase, and

• An increase of $17.2 million in other employee incentives and benefits primarily driven by seasonal expenses relating to additional 401(k) matching contributions as a result of the 2018 annual incentive compensation plan payments and an increase in employer payroll taxes reflective of our increased headcount since the first quarter of 2018, driven by our continued growth initiatives as well as the inclusion of SVB Leerink FTEs mentioned above.

Our variable compensation plans consist primarily of our Incentive Compensation Plan, Direct Drive Incentive Compensation Plan, 401(k) and ESOP Plan, Retention Program and Warrant Incentive Plan (see descriptions in our 2018 Form 10-K). Total costs incurred under these plans were $87.7 million for the three months endedMarch 31, 2019, compared to $53.1 million for the comparable 2018 period. These amounts are included in total compensation and benefits expense discussed above.

Professional Services

Professional services expense was $37.0 million for the three months endedMarch 31, 2019, compared to $28.7 million for the comparable 2018 period. The increase was primarily related to enhancements in our regulatory, risk and compliance infrastructure to support our momentum as we continue to grow both domestically and globally as well as an increase in legal and consulting costs related to the acquisition of SVB Leerink.

Net Occupancy

Net occupancy expense was $16.0 million for the three months endedMarch 31, 2019, compared to $13.6 million for the comparable 2018 period. The increase was primarily due to lease renewals at higher costs, reflective of market conditions, and the expansion of certain offices to support our growth as well as a $1.8 million increase directly attributable to the inclusion of SVB Leerink in our financial results effective January 1, 2019.

FDIC and State Assessments

FDIC and state assessments expense was $4.0 million for the three months endedMarch 31, 2019, compared to $9.4 million for the comparable 2018 period. The decrease was due primarily to the elimination of the FDIC surcharge for banks effective October 1, 2018, reflective of the deposit insurance fund reserve ratio reaching its minimum funding requirements.

79

Business Development and Travel

Business development and travel expense was $15.4 million for the three months endedMarch 31, 2019, compared to $11.2 million for the comparable 2018 period. The increase was to support expansion initiatives as we continue to grow both domestically and globally.

Other Noninterest Expense

Total other noninterest expense was $33.5 million for the three months endedMarch 31, 2019, compared to $18.1 millionfor the comparable2018period. The $15.4 million increase in other noninterest expense for the three months endedMarch 31, 2019was driven primarily by the inclusion of SVB Leerink in our financial results effective January 4, 2019, which contributed $9.6 million to the overall increase related to new expenses for investment banking and trade order execution costs as well as amortization of intangible assets recorded as part of the acquisition.

A summary of other noninterest expense for the three months endedMarch 31, 2019 and 2018 is as follows:

	Three months ended March 31,
(Dollars in thousands)	2019		2018		% Change
Lending and other client related processing costs	$	5,177	$	3,201	61.7	%

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 managed funds’ general partners. A summary of net income attributable to noncontrolling interests for the three months endedMarch 31, 2019 and 2018 is as follows:

	Three months ended March 31,
(Dollars in thousands)	2019			2018			% Change
Net interest income (1)	$	(11	)	$	(9	)	22.2	%
Noninterest income (1)	(2,270		)	(9,522		)	(76.2	)
Noninterest expense (1)	379			(32		)	NM
Carried interest allocation (2)	(978		)	(3,502		)	(72.1	)
Net income attributable to noncontrolling interests	$	(2,880	)	$	(13,065	)	(78.0	)

NM—Not meaningful

(1) Represents noncontrolling interests’ share in net interest income, noninterest income or loss and noninterest expense.

80

(2) Represents the preferred allocation of income (or change in income) earned by us as the general partner of certain consolidated funds.

Three months endedMarch 31, 2019 and 2018

Net income attributable to noncontrolling interests was $2.9 million for the three months endedMarch 31, 2019, compared to $13.1 million for the comparable 2018 period. Net income attributable to noncontrolling interests of $2.9 million for the three months endedMarch 31, 2019 was primarily a result of net gains on investment securities (including carried interest allocation) from our managed funds of funds in the portfolio, related primarily to net unrealized valuation increases for public and private company investments held by the funds in the portfolio. See “Results of Operations—Noninterest Income—Gains on Investment Securities, Net”.

Income Taxes

Our effective income tax expense rate was 27.1 percent for the three months endedMarch 31, 2019, compared to 27.5 percent for the comparable 2018 period. 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 reduction in the effective tax rate for the three months endedMarch 31, 2019 was due primarily to a decrease in non-deductible FDIC premiums due to the elimination of the FDIC surcharge for banks effective October 1, 2018.

Operating Segment Results

We have four segments for which we report our financial information: Global Commercial Bank, SVB Private Bank, SVB Capital and SVB Leerink. SVB Leerink is a new reportable segment for 2019 as a result of the acquisition of SVB Leerink effective January 4, 2019.

We report segment information based on the “management” approach. The management approach designates the internal reporting used by management for making decisions and assessing performance as the source of our reporting segments. Please refer to Note 15—“Segment Reporting” of the “Notes to Interim Consolidated Financial Statements (unaudited)” under Part I, Item 1 of this report for additional details.

The following is our reportable segment information for the three months endedMarch 31, 2019 and 2018:

Global Commercial Bank

	Three months ended March 31,
(Dollars in thousands)	2019			2018			% Change
Net interest income	$	445,876		$	369,867		20.6	%

Total average assets	55,883,000			49,953,396			11.9
Total average deposits	47,596,868			44,041,634			8.1

Three months endedMarch 31, 2019 and 2018

Income before income tax expense from our Global Commercial Bank (“GCB”) increased to $346.7 million for the three months endedMarch 31, 2019, compared to $256.5 million for the comparable 2018 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 endedMarch 31, 2019 compared to the comparable 2018 period are discussed below.

Net interest income from GCB increased by $76.0 million for the three months endedMarch 31, 2019, 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 $26.8 million for the three months endedMarch 31, 2019, compared to $25.3 million for the comparable 2018 period. The provision of $26.8 million for the three months ended March 31, 2019 reflects primarily $27.4 million in net new specific reserves for nonaccrual loans, $4.1 million in additional reserves for period-end loan

81

growth and $4.9 million for charge-offs not specifically reserved for, partially offset by a decrease in the qualitative component of our performing loan reserves of $5.3 million reflective of the continued growth of larger, higher credit quality private equity/venture capital loans as a percentage of total gross loans.

The provision of $25.3 million for the three months endedMarch 31, 2018 primarily reflected $11.3 million in net new specific reserves for nonaccrual loans and a $14.0 million increase in reserves for period-end loan growth.

Noninterest income increased by $27.5 million for the three months endedMarch 31, 2019 related primarily to an overall increase in our non-GAAP core fee income (higher client investment fees, credit card fees and foreign exchange fees). These increases were 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 $11.8 million for the three months endedMarch 31, 2019, due primarily to increased compensation and benefits expense. Compensation and benefits expense increased as a result of higher salaries and wages expenses and higher other employee compensation and 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 351 to 2,252 FTEs for the three months ended March 31, 2019, compared to 1,901 FTEs for the comparable 2018 period.

SVB Private Bank

	Three months ended March 31,

Total average deposits	1,491,234			1,572,424			(5.2	)

Three months endedMarch 31, 2019 and 2018

Net interest income from our SVB Private Bank decreased by $4.3 million for the three months endedMarch 31, 2019, due primarily to higher interest paid on interest-bearing deposits due to market rate adjustments for the three months ended March 31, 2019 as compared to the 2018 comparable period.

Noninterest expense increased by $0.8 million for the three months endedMarch 31, 2019, due primarily to increased compensation and benefits expense. Compensation and benefits expense increased as a result of increased salaries and wages, reflective of the increase in number of average FTE since the first quarter of 2018, and higher incentive compensation expenses, reflective primarily of our strong 2019 full-year expected performance as compared to 2018.

SVB Capital

Income before income tax expense	$	19,069		$	23,871		(20.1	)
Total average assets	$	378,732		$	373,322		1.4

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 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

82

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.

Three months endedMarch 31, 2019 and 2018

SVB Capital had noninterest income of $24.8 million for the three months ended March 31, 2019, compared to $28.9 million for the comparable 2018 period. The decrease in noninterest income was due primarily to lower net gains on investment securities compared to the comparable 2018 period. SVB Capital’s components of noninterest income primarily include the following:

• Net gains on investment securities of $15.9 million for the three months ended March 31, 2019, compared to net gains of $22.9 million for the comparable 2018 period. The net gains on investment securities of $15.9 million were related primarily to gains from our strategic venture capital fund investments reflective of net unrealized valuation increases in public company securities held in our strategic venture capital funds, and

• Fund management fees of $6.7 million for the three months ended March 31, 2019, compared to $5.7 million for the comparable 2018 period.

SVB Leerink’s components of noninterest income primarily include investment banking revenue, commissions and 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 discussed below are net of noncontrolling interests.

Three months endedMarch 31, 2019

SVB Leerink had noninterest income of $68.1 million for the three months ended March 31, 2019, primarily driven by $49.8 million of investment banking revenue, $14.1 million of commissions and $1.4 million in fund management fees.

SVB Leerink had noninterest expense $60.5 million for the three months ended March 31, 2019, primarily driven by $42.9 million in compensation and benefits expense and $10.9 million in other noninterest expense, driven by investment banking and trade order execution costs as well as amortization of intangible assets recorded as part of the acquisition.

Consolidated Financial Condition

Our total assets, and total liabilities and stockholders' equity, were $60.2 billion at March 31, 2019 compared to $56.9 billion at December 31, 2018, an increase of $3.3 billion, or 5.7 percent. Refer below to a summary of the individual components driving the changes in total assets, total liabilities and stockholders' equity.

Cash and Cash Equivalents

Cash and cash equivalents totaled $7.1 billion at March 31, 2019, an increase of $3.5 billion, or 97.9 percent, compared to $3.6 billion at December 31, 2018. As of March 31, 2019, $4.7 billion 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 $1.4 billion. As of December 31, 2018, $1.7 billion 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 $1.2 billion.

83

Investment Securities

Investment securities totaled $22.8 billion at March 31, 2019, a decrease of $1.4 billion, or 5.9 percent, compared to $24.2 billion at December 31, 2018. Our investment securities portfolio is comprised of: (i) an available-for-sale securities portfolio and a held-to-maturity securities portfolio, both of which represent interest earning fixed income investment securities; and (ii) a non-marketable and other equity securities portfolio, which represents primarily investments managed as part of our funds management business as well as public equity securities held as a result of equity warrant assets exercised.

Available-for-Sale Securities

Period-end available-for-sale securities were $6.8 billion at March 31, 2019 compared to $7.8 billion at December 31, 2018, a decrease of $1.0 billion, or 13.3 percent. The $1.0 billion decrease in period-end AFS securities balances from December 31, 2018 to March 31, 2019, was due primarily to the sale of $1.2 billion of AFS securities comprised of U.S. Treasury notes, partially offset by purchases of $0.2 billion.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 2019, the AFS portfolio had unrealized gains of $46.8 million ($33.8 million net of tax), driven primarily by decreases in 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 March 31, 2019. 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, U.S. agency debentures and foreign government debt securities, 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.

Held-to-Maturity Securities

Period-end held-to-maturity securities were $15.1 billion at March 31, 2019 compared to $15.5 billion at December 31, 2018, a decrease of $0.4 billion, or 2.8 percent. The $0.4 billion decrease in period-end HTM security balances from December 31, 2018 to March 31, 2019 was due primarily to pay downs and maturities.

84

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 March 31, 2019. 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 21.0 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. The estimated weighted-average duration of our fixed income investment securities portfolio was 3.7 years and 3.8 years at March 31, 2019 and December 31, 2018, 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 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 equity securities compared to the amounts attributable to SVBFG.

Period-end non-marketable and other equity securities were $975.0 million at March 31, 2019 compared to $941.1 million at December 31, 2018, an increase of $33.9 million, or 3.6 percent. Non-marketable and other equity securities, net of noncontrolling interests were $840.8 million at March 31, 2019, compared to $806.1 million at December 31, 2018.The increase was primarily attributable to $31.6 million in additional non-marketable and other equity securities reflective of the inclusion of SVB Leerink in our financial results beginning on January 4, 2019. The following table summarizes the carrying value (as reported) of non-marketable and other equity securities compared to the amounts attributable to SVBFG (which generally represents the carrying value times our ownership percentage) at March 31, 2019 and December 31, 2018:

(2) The carrying value represents investments in 212 and 213 funds (primarily venture capital funds) at March 31, 2019 and December 31, 2018, 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.Our unconsolidated venture capital and private equity fund investments are carried at fair value based on the fund investments' net asset values per share as obtained from the general partners of the funds. For each fund

86

investment, 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 31^st, for our March 31^st consolidated financial statements, adjusted for any contributions paid, distributions received from the investment, and significant fund transactions or market events during the reporting period.

(3) Investments classified as "Other investments without a readily determinable fair value" 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 7—“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 equity investments in public companies held by our consolidated funds. Changes in the fair value recognized through net income.

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.

87

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 March 31, 2019, such prohibited investments had an estimated aggregate carrying value and fair value of approximately $224.7 million. (For more information about the Volcker Rule, see “Business—Supervision and Regulation” under Part 1, Item 1 of our 2018 Form 10-K.)

Loans

Loans, net of unearned income, increased by $0.5 billion to $28.9 billion at March 31, 2019, compared to $28.3 billion at December 31, 2018. Unearned income was $170 million at March 31, 2019 and $173 million at December 31, 2018. Total gross loans were $29.0 billion at March 31, 2019, an increase of $0.5 billion, compared to $28.5 billion at December 31, 2018. Period-end loans increased compared to December 31, 2018, driven primarily by loan growth in our private equity/venture capital portfolio as well as from our life science/healthcare, private bank and premium wine portfolios.

At December 31, 2018, gross loans equal to or greater than $20 million to any single client (individually or in the aggregate) totaled $14.5 billion, or 50.8 percent of our total gross loan portfolio. These loans represented 361 clients, and of these loans, $27.5 million were on nonaccrual status as of December 31, 2018.

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 the various 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 March 31, 2019 and December 31, 2018. 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 the 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 nine percent and eight percent of total gross loans at March 31, 2019 and December 31, 2018, respectively. 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, represented two and one percent of total gross loans at both March 31, 2019 and December 31, 2018. 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, represented 15 percent of total gross loans at March 31, 2019, compared to 16 percent at December 31, 2018. 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

90

of all fixed charges associated with operating the business. Sponsored buyout loans represented seven percent of total gross loans at March 31, 2019 compared to eight percent at December 31, 2018. 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 March 31, 2019, our lending to private equity/venture capital firms and funds represented 49 percent of total gross loans, compared to 50 percent of total gross loans at December 31, 2018. 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 March 31, 2019 and December 31, 2018. Many of these clients have mortgages, which represented 86 percent of this portfolio at March 31, 2019; 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 28 percent and 11 percent of our outstanding total gross loan balances as of March 31, 2019 were to borrowers based in California and New York, respectively, compared to 28 percent and 10 percent as of December 31, 2018. Other than California and New York, there are no states with gross loan balances greater than or equal to 10 percent.

See generally “Risk Factors–Credit Risks” set forth under Part I, Item 1A in our 2018 Form 10-K.

Credit Quality Indicators

As of March 31, 2019 and December 31, 2018, our total criticized loans and impaired loans both represented four percentof our total gross loans. Criticized and impaired loans to early-stage clients represented 19 percent of our total criticized and impaired loan balances at both March 31, 2019 and December 31, 2018.Loans to early-stage clients represent a relatively small percentage of our overall portfolio at six percent of total gross loans at both March 31, 2019 and December 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:

(Dollars in thousands)	March 31, 2019			December 31, 2018
Gross nonperforming, past due, and restructured loans:
Nonaccrual loans	$	133,623		$	94,142
Loans past due 90 days or more still accruing interest	2,148			1,964

(1) The “allowance for unfunded credit commitments” is included as a component of other liabilities and any provision is included in the “provision for credit losses” in the statement of income. See “Provision for Credit Losses” for a discussion of the changes to the allowance.

(2) Includes unfunded loan commitments and letters of credit.

Our allowance for loan losses as a percentage of total gross loans increased 4 basis points to 1.03 percent at March 31, 2019, compared to 0.99 percent at December 31, 2018 reflective of an increase in reserves for nonaccrual loans of 8 basis points offset by a decrease in the reserves for gross performing loans of 4 basis points.

Our allowance for loan losses for performing loans was $238.9 million at March 31, 2019, compared to $243.0 million at December 31, 2018.The $4.1 million decrease in reserves for performing loans was driven primarily by an $8.2 million decrease reflective of the continued growth in our private equity/venture capital loans, which tend to be of higher credit quality, partially offset by $4.1 million in additional reserves for period-end loan growth.

Our allowance for loan losses for nonaccrual loans was $61.2 million at March 31, 2019, compared to $37.9 million at December 31, 2018.The $23.3 million increase in the reserves for nonaccrual loans was due to new nonaccrual loan reserves of $33.4 million driven primarily by two clients in our life science/healthcare loan portfolio, partially offset by $10.1 million of repayments and charge-offs.

The following table presents a summary of changes in nonaccrual loans for the three months endedMarch 31, 2019 and 2018: 

	Three months ended March 31,
(Dollars in thousands)	2019			2018
Balance, beginning of period	$	94,142		$	119,259
Additions	50,857			21,803
Paydowns	(6,430		)	(17,248		)
Charge-offs	(4,895		)	(7,112		)
Other reductions	(51		)	(35		)
Balance, end of period	$	133,623		$	116,667

Our nonaccrual loans as of March 31, 2019 included $102.6 million from six clients (three software/internet clients represented $54.6 million and three life science/healthcare clients represented $48.0 million).Two of these loans are sponsored buyout loans that were added to our nonaccrual portfolio in 2015, another is a Corporate Finance client that was added during 2016, one is a Growth client that was added during 2018 and two are new nonaccrual loans added during 2019 from our Growth practice. The total credit exposure for these six largest nonaccrual loans was $104.1 million as of March 31, 2019, for which we have specifically reserved $47.5 million.

Average nonaccrual loans for the three months endedMarch 31, 2019 were $106.4 millioncompared to $111.6 million for the comparable 2018 period.The $5.2 million decrease in average nonaccrual loans for the three months ended March 31, 2019 compared to March 31, 2018 was primarily from our software/internet and hardware loan portfolios partially offset by increases in the average nonaccrual loans in our life science/healthcare and private equity/venture capital loan portfolios. If the nonaccrual loans had not been nonperforming, $1.7 million in interest income would have been recorded for the three months endedMarch 31, 2019 compared to $1.9 million for the comparable 2018 period.

Accrued Interest Receivable and Other Assets

A summary of accrued interest receivable and other assets at March 31, 2019 and December 31, 2018 is as follows:

(1) See “Derivatives” section below.

Foreign Exchange Spot Contract Assets

Foreign exchange spot contract assets represent unsettled client trades at the end of the period. The increase of $223.3 million was primarily due to an overall increase in activity at period-end as compared to December 31, 2018.

Other Assets

Other assets includes various asset amounts for other operational transactions. The increase of $65.5 million was primarily due to $33.3 million in other assets attributable to the inclusion of SVB Leerink in our financial results beginning January 4, 2019. Prepaid assets increased $16.0 million primarily due to the annual timing of prepaid software agreement renewals and merchant card receivable increased $16.8 million due to the timing of settlement.

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 March 31, 2019, we held warrants in 2,149 companies, compared to 2,095 companies at December 31, 2018. Warrants in 26 companies each had values greater than $1.0 million and collectively represented $56.8 million, or 35.0 percent, of the fair value of the total warrant portfolio at March 31, 2019. 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 months endedMarch 31, 2019 and 2018: 

	Three months ended March 31,
(Dollars in thousands)	2019			2018
Balance, beginning of period	$	149,238		$	123,763
New equity warrant assets	4,471			5,099
Non-cash changes in fair value, net	16,238			10,186
Exercised equity warrant assets	(7,317		)	(2,457		)
Terminated equity warrant assets	(415		)	(922		)
Balance, end of period	$	162,215		$	135,669

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, net of cash collateral, was $28.5 million at March 31, 2019 and $20.7 million at December 31, 2018. For additional information on our foreign exchange forward contracts and foreign currency option contracts, see Note 12—“Derivative Financial Instruments” of the “Notes to Interim Consolidated Financial Statements (unaudited)” under Part I, Item 1 of this report.

94

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, net of cash collateral, was $11.6 million at March 31, 2019 and $8.7 million at December 31, 2018. For additional information on our client interest rate derivatives, see Note 12—“Derivative Financial Instruments” of the “Notes to Interim Consolidated Financial Statements (unaudited)” under Part I, Item 1 of this report.

Interest Rate Swaps

To manage interest rate risk on our variable-interest rate loan portfolio, we enter into interest rate swap contracts to hedge against future changes in interest rates by using hedging instruments to lock in future cash inflows that would otherwise be impacted by movements in the market interest rates. We designate these interest rate swap contracts as cash flow hedges that qualify for hedge accounting under ASC 815 and record them in other assets and other liabilities. For additional information on our interest rate swaps, see Note 12—“Derivative Financial Instruments” of the “Notes to Interim Consolidated Financial Statements (unaudited)” and "Quantitative and Qualitative Disclosures about Market Risk" under Part I, Item 1 of this report.

Deposits

Deposits were $52.3 billion at March 31, 2019, an increase of $3.0 billion, or 6.1 percent, compared to $49.3 billion at December 31, 2018. The increase in deposits was driven primarily by growth across a majority of our portfolio segments. The leading contributors were our Technology and Life Science client portfolios, attributable primarily to a healthy equity funding environment, tempered growth in the IPO and secondary public offering markets as well as continued healthy new client acquisition.

At March 31, 2019, the aggregate balance of time deposit accounts individually equal to or greater than $100,000 totaled $44 million, compared to $46 million at December 31, 2018. At March 31, 2019, all the time deposit accounts individually equal to or greater than $100,000 were scheduled to mature within one year. No material portion of our deposits has been obtained from a single depositor and the loss of any one depositor would not materially affect our business. Approximately 15 percent and 16 percent of our total deposits at March 31, 2019 and December 31, 2018, respectively, were from our clients in Asia.

Short-Term Borrowings

As of March 31, 2019, we had no overnight borrowings and $14.5 million in other short-term borrowings consisting of cash collateral received from certain counterparties in relation to market value exposures of derivative contracts in our favor. As of December 31, 2018, we had $0.6 billion in short-term borrowings, consisting of $0.3 billion in advances from the FHLB and $0.3 billion in securities sold under an agreement to repurchase. For more information on our short-term debt, see Note 11—“Short-Term Borrowings and Long-Term Debt” of the “Notes to Interim Consolidated Financial Statements (unaudited)” under Part I, Item 1 of this report.

Long-Term Debt

Our long-term debt was $696.7 million at March 31, 2019 and $696.5 million at December 31, 2018. As of March 31, 2019, long-term debt included our 3.50% Senior Notes and 5.375% Senior Notes. For more information on our long-term debt, see Note 11—“Short-Term Borrowings and Long-Term Debt” of the “Notes to Interim Consolidated Financial Statements (unaudited)” under Part I, Item 1 of this report.

Other Liabilities

A summary of other liabilities at March 31, 2019 and December 31, 2018 is as follows:

(Dollars in thousands)	March 31, 2019		December 31, 2018		% Change
Foreign exchange spot contract liabilities, gross	$	562,773	$	170,355	NM

(1) See “Derivatives” section above.

Foreign Exchange Spot Contract Liabilities

Foreign exchange spot contract liabilities represent unsettled client trades at the end of the period. The increase of $392.4 million was due primarily to increased client trade activity at period-end as compared to December 31, 2018.

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 $108.5 million was primarily the result of the payout of our 2018 incentive compensation plans during the first quarter of 2019, partially offset by higher accruals for the three months ended March 31, 2019 primarily due to the increase in the number of average FTEs for the first quarter of 2019.

Other Liabilities

Other liabilities includes various accrued liability amounts for other operational transactions. The increase of $146.3 million was reflective primarily of a $64.3 million increase in current taxes payable, an increase in accrued accounts payable for $39.7 million and a $17.5 million increase in new commitments for our qualified affordable tax credit funds at March 31, 2019 as compared to December 31, 2018. In addition, an increase of $29.9 million in other liabilities was attributable to the inclusion of SVB Leerink in our financial results effective January 4, 2019.

Noncontrolling Interests

Noncontrolling interests totaled $141.1 million and $148.6 million at March 31, 2019 and December 31, 2018, respectively. The $7.5 million decrease was due primarily to net distributions of $15.7 million to limited partners from various managed funds of funds, offset by income attributable to noncontrolling interests of $2.9 million as well as an additional $5.3 million attributable to the inclusion of SVB Leerink in our financial results for the three months endedMarch 31, 2019.

Fair Value Measurements

The following table summarizes our financial assets and liabilities that are measured at fair value on a recurring basis as of March 31, 2019 and December 31, 2018:

	March 31, 2019						December 31, 2018
(Dollars in thousands)	Total Balance			Level 3			Total Balance			Level 3
Assets carried at fair value	$	7,338,938		$	157,784		$	8,388,011		$	146,278
As a percentage of total assets	12.2		%	0.3		%	14.7		%	0.3		%
Liabilities carried at fair value	$	91,612		$	—		$	98,050		$	—
As a percentage of total liabilities	0.2		%	—		%	0.2		%	—		%
As a percentage of assets carried at fair value				2.1		%				1.7		%

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 18—“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 2018 Form 10-K.

96

During the three months endedMarch 31, 2019, the Level 3 assets that are measured at fair value on a recurring basis experienced net realized and unrealized gains of $19.1 million, primarily reflective of valuation increases from our private company warrant portfolio driven by healthy funding rounds and net gains realized on exercised warrant assets due to IPO activity. During the three months endedMarch 31, 2018, the Level 3 assets that are measured at fair value on a recurring basis experienced net realized and unrealized gains of $18.7 million, attributable primarily to net gains from exercises of equity warrant assets driven by M&A activity and valuation increases in our private company warrant portfolio.

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, including the joint agency rules implementing the "Basel III" capital rules. 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 $5.3 billion at March 31, 2019, an increase of $226.6 million, or 4.4 percent, compared to $5.1 billion at December 31, 2018. This increase was due primarily to net income of $288.7 million and a decrease in accumulated other comprehensive loss reflective primarily of a $46.8 million ($33.8 million net of tax) increase in the fair value of our AFS securities portfolio driven by decreases in period-end market interest rates. The increases were partially offset by a $116.0 million decrease in SVBFG stockholders' equity related to the repurchase of our outstanding common stock.

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 March 31, 2019 and December 31, 2018. Capital ratios for SVB Financial and the Bank, compared to the minimum regulatory ratios applicable to bank holding companies and banks to be considered “well capitalized” and “adequately capitalized," are set forth below:

					Minimum Ratios under Applicable Regulatory Capital Adequacy Requirements
	March 31, 2019		December 31, 2018		“Well Capitalized”		“Adequately  Capitalized”
SVB Financial:
CET 1 risk-based capital ratio	12.89	%	13.41	%	6.5	%	4.5	%
Tier 1 risk-based capital ratio	13.04		13.58		8.0		6.0
Total risk-based capital ratio	13.94		14.45		10.0		8.0
Tier 1 leverage ratio	9.10		9.06		N/A		4.0
Tangible common equity to tangible assets ratio (1)	8.59		8.99		N/A		N/A
Tangible common equity to risk-weighted assets ratio (1)	12.86		13.28		N/A		N/A
Bank:
CET 1 risk-based capital ratio	12.35	%	12.41	%	6.5	%	4.5	%
Tier 1 risk-based capital ratio	12.35		12.41		8.0		6.0
Total risk-based capital ratio	13.29		13.32		10.0		8.0
Tier 1 leverage ratio	8.38		8.10		5.0		4.0
Tangible common equity to tangible assets ratio (1)	7.99		8.13		N/A		N/A
Tangible common equity to risk-weighted assets ratio (1)	12.32		12.28		N/A		N/A

97

(1) See below for a reconciliation of non-GAAP tangible common equity to tangible assets and tangible common equity to risk-weighted assets.

Risk-based capital ratios (CET 1, tier 1, and total risk-based capital) for SVB Financial decreased as of March 31, 2019, compared to the same ratios as of December 31, 2018 as a result of an increase in risk-weighted assets, primarily driven by increases in funded loans and loan commitments.

Risk-based capital ratios (CET 1, tier 1, and total risk-based capital) for the Bank decreased as of March 31, 2019, compared to the same ratios as of December 31, 2018. The decrease in the Bank's capital ratios reflected $167.0 million of cash dividends paid by the Bank to our bank holding company, SVB Financial, during the three months ended March 31, 2019.

Both SVB Financial and the Bank's tier 1 leverage ratios increased as of March 31, 2019, compared to December 31, 2018, due to proportionally higher capital from net income as well as a decrease in average assets during the first quarter of 2019. 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 following table provides a reconciliation of non-GAAP financial measures with financial measures defined by GAAP for SVB Financial and the Bank for the periods ended March 31, 2019 and December 31, 2018:

	SVB Financial						Bank
Non-GAAP tangible common equity and tangible assets    (Dollars in thousands, except ratios)	March 31, 2019			December 31, 2018			March 31, 2019			December 31, 2018
GAAP SVBFG stockholders’ equity	$	5,342,773		$	5,116,209		$	4,696,564		$	4,554,814
Less: intangible assets	193,219			—			—			—
Tangible common equity	$	5,149,554		$	5,116,209		$	4,696,564		$	4,554,814
GAAP total assets	$	60,160,285		$	56,927,979		$	58,774,326		$	56,047,134
Less: intangible assets	193,219			—			—			—
Tangible assets	$	59,967,066		$	56,927,979		$	58,774,326		$	56,047,134
Risk-weighted assets	$	40,048,892		$	38,527,853		$	38,132,316		$	37,104,080
Non-GAAP tangible common equity to tangible assets	8.59		%	8.99		%	7.99		%	8.13		%
Non-GAAP tangible common equity to risk-weighted assets	12.86			13.28			12.32			12.28

The tangible common equity to tangible assets ratio decreased for the Bank primarily as a result of the $167.0 million in cash dividends paid by the Bank to our bank holding company, SVB Financial Group, during the three months ended March 31, 2019. The tangible common equity to risk-weighted assets ratio decreased for the Bank as a result of the proportionally higher increase in risk-weighted assets relative to the increase in tangible common equity. The growth in period-end risk-weighted assets was primarily due to increases in cash and cash equivalents and period-end loan growth.

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 16—“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 16—“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 March 31, 2019, our period-end total deposit balances were $52.3 billion, compared to $49.3 billion at December 31, 2018.

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 and unsecured basis. Our secured facilities include collateral pledged to the FHLB of San Francisco and the discount window at the FRB (using both fixed income securities and loans as collateral). Our unsecured facility consists of our uncommitted federal funds lines. As of March 31, 2019, collateral pledged to the FHLB of San Francisco was comprised primarily of fixed income investment securities and loans and had a carrying value of $4.5 billion, of which $4.0 billion was available to support additional borrowings. As of March 31, 2019, collateral pledged to the discount window at the FRB was comprised of fixed income investment securities and had a carrying value of $0.9 billion, all of which was unused and available to support additional borrowings. Our total unused and available borrowing capacity for our uncommitted federal funds lines totaled $1.9 billion at March 31, 2019. Our total unused and available borrowing capacity under our master repurchase agreements with various financial institutions totaled $3.3 billion at March 31, 2019.

On a stand-alone basis, SVB Financial’s primary liquidity channels include dividends from the Bank, its portfolio of liquid assets, and its ability to raise debt and capital. Consistent with recent prior quarters, the Bank has paid a quarterly dividend to SVB Financial. For the three months endedMarch 31, 2019, the dividend amount paid was $167.0 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 2018 Form 10-K.

Consolidated Summary of Cash Flows

Below is a summary of our average cash position and statement of cash flows for the three months endedMarch 31, 2019 and 2018. For further details, see our “Interim Consolidated Statements of Cash Flows (Unaudited)” under Part I, Item 1 of this report.

Average cash and cash equivalents increased by $1.9 billion, or 60.2 percent, to $5.0 billion for the three months endedMarch 31, 2019, compared to $3.1 billion for the comparable 2018 period.

Cash provided by operating activities was $340.8 million for the three months endedMarch 31, 2019, reflective primarily of net income before noncontrolling interests of $291.6 million and $49.1 million net increase in adjustments to reconcile net income to net cash.

Cash provided by investing activities of $0.9 billion for the three months endedMarch 31, 2019was driven by net cash flows of $1.5 billion driven by sales and maturities from our fixed income securities portfolio, partially offset by a $0.5 billion increase in loans and a net cash outflow, adjusted for cash acquired, of $100.0 million for the purchase of SVB Leerink.

Cash provided by financing activities was $2.3 billion for the three months endedMarch 31, 2019, reflective primarily of a net increase of $3.0 billion in deposits, partially offset by $0.6 billion in paydowns of our short-term overnight borrowings and a $0.1 billion outflow related to repurchases of our outstanding common stock.

Cash and cash equivalents were $7.1 billion and $2.6 billion, respectively, at March 31, 2019 and 2018.

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.

100

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. 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. For the NII simulation, market rates as well as the size and composition of the balance sheet are held constant over the simulation horizon. Simulated cash flows during the scenario horizon are assumed to be replaced as they occur, which maintains the balance sheet at its current size and composition. 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 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 percent, which means deposit repricing is assumed to be approximately 35 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.

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 ("bps") at March 31, 2019 and December 31, 2018:

Change in interest rates (bps) (Dollars in thousands)	Estimated		Estimated Increase/(Decrease) in EVE					Estimated		Estimated Increase/(Decrease) in NII

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.

101

Our base EVE as of March 31, 2019 decreased from December 31, 2018 by $11 million, driven by changes in balance sheet composition as well as changes in interest rates, including the shape of the yield curve, which was inverted from the 12-month point to the 10-year point relative to short-term rates. At March 31, 2019, as compared to December 31, 2018, total loan balances increased by $0.5 billion, primarily in Prime and LIBOR indexed variable rate loans. Total fixed income securities decreased by $1.5 billion due primarily to an increase in cash holdings driven by total deposit growth of approximately $3.0 billion during the three months ended March 31, 2019.

Overall balance sheet growth contributed to a $199 million increase in total base EVE, however, this was offset by a decrease of $210 million as a result of lower LIBOR/swap rates across the curve. Due to liquidity needs, approximately $1.2 billion of U.S. Treasury securities were sold during the first quarter of 2019. This caused a $142 million increase in EVE sensitivity in the -200 bps rate shock scenario because the remaining securities have greater prepayment exposure as rates move down. Changes to EVE sensitivity in the other scenarios were relatively small compared to December 31, 2018.

12-Month Net Interest Income Simulation

Our static 12-month NII forecast at March 31, 2019 decreased compared to December 31, 2018 by $48 million, primarily due to changes in our balance sheet composition. Specifically, interest bearing deposit balances increased by $2.8 billion during the three months ended March 31, 2019, resulting in an increase in the simulated 12-month base case interest expense of approximately $86 million. In addition, decreased fixed income securities, as previously mentioned above, combined with increased cash balances at March 31, 2019, translated into simulated 12-month interest income growth of approximately $24 million.

A majority of our loans are indexed to Prime and LIBOR. In the positive parallel simulated rate shock scenarios, interest income on assets that are tied to variable rate indexes, primarily our variable rate loans, are expected to benefit our base 12-month NII projections. The opposite is true for negative rate shock scenarios.

The 12-month NII simulations include repricing assumptions on our interest bearing deposit products which we set 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 amount of simulated changes in short-term market interest rates.

NII sensitivity is measured as the percentage change in projected 12-month net interest income earned in +/- 100 and +/- 200 basis point interest rate shock scenarios compared to a base scenario where balances and interest rates are held constant over the forecast horizon. At March 31, 2019, NII sensitivity was 14.3 percent in the +100 bps interest rate scenario, compared to 13.1 percent at December 31, 2018. Our NII sensitivity in the +200 bps interest rate shock scenario was 28.7 percent compared to 26.1 percent at December 31, 2018.NII sensitivity in the -100 bps scenario of negative 14.4 percent was higher at March 31, 2019 compared to a negative 13.3 percent at December 31, 2018. The -200 bps scenario currently indicates a higher percentage change in NII of negative 28.8 percent at March 31, 2019 compared to negative 26.7 percent at December 31, 2018. At March 31, 2019, NII sensitivity percentages are inclusive of the income or expense associated with interest rate swaps that are part of our hedging initiatives which began during the three months ended March 31, 2019, in an effort to reduce the impact of potential decreasing rates on NII. The changes in NII sensitivity are primarily the result of the changes in balance sheet composition described previously.

The simulation model used in the above analysis incorporates embedded floors on loans, where present, 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 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.

102

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

Except 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, 2019, we implemented ASC 842, Leases. Although the new lease standard had an immaterial impact on our consolidated financial statements, we did implement changes to our processes related to recognition and the control activities to properly identify and record them.  These included the development of new policies, new controls, new training, ongoing contract review requirements, and gathering of information provided for disclosures.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

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 diverse set 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 months endedMarch 31, 2019 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, 2018 (“2018 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 2018 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 based on 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) the 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 February 2016, the FASB issued a new accounting standard update (ASU 2016-02, Leases (Topic 842)), which requires for all operating leases the recognition of a right-of-use ("ROU") asset and a corresponding lease liability, in the statement of financial position. For short term leases (term of 12 months or less), a lessee is permitted to make an accounting election not to recognize lease assets and lease liabilities. The lease cost will be allocated over the lease term on a straight-line basis. There were further amendments, including practical expedients, with the issuance of ASU 2018-01, “Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842” in January 2018. In July 2018 the FASB issued ASU No. 2018-11, "Leases (Topic 842): Targeted Improvements", which provides us with the option to apply the new leasing standard to all open leases as of the adoption date, on a prospective basis.

On January 1, 2019, we adopted the new accounting standard ASU 2016-02, Leases (Topic 842) and all the related amendments ("new lease standard", "ASC 842" or "ASU 2016-02") utilizing the practical expedient to apply the new lease standard as of the January 1, 2019 on a prospective basis. We also elected the "package of expedients" and elected as an accounting policy to exclude recording ROU assets and lease liabilities for leases that meet the definition of short-term leases. In addition to excluding short-term leases, we have implemented an accounting policy in which non-lease components are not separated from lease components in the measurement of ROU assets and lease liabilities for all lease contracts. The "package of expedients" allowed us to continue to account for existing leases for which the commencement date is before January 1, 2019, in accordance with the previous guidance, Leases (Topic 840), throughout the lease term, including periods after adoption of the new guidance. We recognized $146 million in ROU assets and $178 million in lease liabilities as a result of applying the new lease standard as an adjustment to our opening consolidated balance sheet on January 1, 2019. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. See Note 9—"Leases" of the “Notes to Interim Consolidated Financial Statements (unaudited)” under Part I, Item 1 of this report for additional disclosures related to our leases.

In March 2017, the FASB issued ASU No. 2017-08, Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities, which amends the amortization period for certain purchased callable debt securities held at a premium. The ASU requires entities to amortize premiums on debt securities by the first call date when the securities have fixed and determinable call dates and prices. The scope of the ASU includes all accounting premiums, such as purchase premiums and cumulative fair value hedge adjustments. The ASU does not change the accounting for discounts, which continue to be recognized over the contractual life of a security. Adoption of the ASU is on a modified retrospective basis through a cumulative effect adjustment to retained earnings as of the beginning of the year of adoption. Adoption of the ASU primarily affected our HTM portfolio of callable state and municipal debt securities. On January 1, 2019, we adopted the ASU and recognized a net reduction to retained earnings of $583 thousand.

Recent Accounting Pronouncements

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 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 2018, the FASB issued a new accounting standard update (ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement). The ASU primarily modifies certain disclosures with respect to Level 3 fair value measurements. This guidance will be effective January 1, 2020, with early adoption permitted. This guidance will not have an impact on our consolidated financial position or results of operations, and we do not expect the adoption of this standard to have a material impact on the disclosures in our Notes to the Consolidated Financial Statements.

Business Combinations [Abstract]

Business Combination

Business Combination

On January 4, 2019, we completed the acquisition of Leerink Holdings LLC, the Boston-based parent company of healthcare and life science investment bank Leerink Partners LLC, now SVB Leerink Holdings LLC ("SVB Leerink"). The acquisition was previously announced on November 13, 2018. SVB Leerink is an investment bank specializing in Equity & Convertible Capital Markets, Mergers & Acquisitions, Equity Research and Sales & Trading for growth and innovation-minded healthcare and life science companies and operates as a wholly-owned subsidiary of SVB Financial.

The acquisition was accounted for as a business combination and accordingly, the results of SVB Leerink's operations have been included in the Company's consolidated statement of income for the three months ended March 31, 2019 from the date of acquisition. We acquired SVB Leerink for approximately $270.9 million comprised of cash and share-based replacement award liabilities. The previously announced agreed upon purchase price of $280.0 million included $9.1 million of post-combination expenses related to share-based replacement awards. In addition, we provided a retention pool for employees of $60.0 million to be paid over five years comprised of a mix of cash and equity issued under the Company's current Equity Incentive Plan. Refer to Note 4—“Share-Based Compensation” of the “Notes to Interim Consolidated Financial Statements (unaudited)” under Part I, Item 1 of this report for more information. The following table summarizes the allocation of the purchase price to the net assets of SVB Leerink as of January 4, 2019:

(Dollars in thousands)	January 4, 2019
Cash paid	$	263,310
Replacement award liabilities (1)	7,629
Total purchase consideration	$	270,939
Fair value of net assets acquired	135,749
Goodwill	$	135,190

(1) The replacement award liabilities recognized as part of the total purchase consideration and the post-combination expenses of $9.1 million related to share-based replacement awards will be paid out in cash in accordance with SVB Leerink's original grant date vesting schedules.

The following table summarizes the estimated fair value of assets acquired and liabilities assumed at the date of acquisition:

(Dollars in thousands)	January 4, 2019
Assets acquired:
Cash and cash equivalents	$	163,273
Investment securities	32,986
Accounts receivable	37,538
Intangible assets	60,900
Other assets	35,128
Total assets acquired	329,825
Liabilities assumed:

Other liabilities	33,131
Noncontrolling interests	5,256
Total liabilities assumed	194,076
Fair value of net assets acquired	$	135,749

The Company recognized provisional identifiable intangible assets of $60.9 million and goodwill of $135.2 million as a result of the acquisition. The goodwill recorded includes revenue generating synergies expected from collaboration between SVB Leerink and the Company. All reported goodwill amounts have been allocated to the SVB Leerink reporting segment and are expected to be deductible for tax purposes. The Company recorded intangible assets of $60.9 million, which are subject to amortization over their estimated useful lives. These fair value estimates represent our best estimate of fair value at March 31, 2019. The final amounts are subject to the completion of the fiscal 2018 financial statement audit of Leerink Holdings LLC, which is expected to be completed during the second quarter of 2019. The fair value of the noncontrolling interests in Leerink Holdings LLC represents the noncontrolling ownership percentage for SVB Leerink's consolidated VIE investment securities which are measured at net asset value.

The following table summarizes the fair value and estimated useful lives of the other intangible assets at the date of acquisition:

(Dollars in thousands)	Estimated Fair Value		Weighted Average Estimated Useful Life - in Years
Other intangible assets:
Customer relationships	$	42,000	11.0
Other	18,900		9.9
Total other intangible assets	$	60,900

SVB Leerink's net income from January 4, 2019 through March 31, 2019 was approximately $5.8 million. Supplementary pro forma financial information related to the acquisition is not included because the impact to the Company's consolidated statements of income is not material. The following table represents the amount of revenue and earnings attributable to SVB Leerink that is included in our financial results from January 4, 2019 through March 31, 2019:

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 unit awards 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 months endedMarch 31, 2019 and 2018:

Our involvement with VIEs includes our investments in venture capital and private equity funds, debt funds, private and public portfolio companies and qualified affordable housing projects.

The following table presents the carrying amounts and classification of significant variable interests in consolidated and unconsolidated VIEs as of March 31, 2019 and December 31, 2018:

(1) Included in our unconsolidated non-marketable and other equity securities portfolio at March 31, 2019 and December 31, 2018 are investments in qualified affordable housing projects of $339.9 million and $318.6 million, respectively, and related other liabilities consisting of unfunded credit commitments of $223.2 million and $205.7 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 qualified affordable housing projects. A majority of these investments are through third- 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 16—“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 7—“Investment Securities" of the “Notes to Interim Consolidated Financial Statements (unaudited)” under Part I, Item 1 of this report.

As of March 31, 2019, our exposure to loss with respect to the consolidated VIEs is limited to our net assets of $227.6 million and our exposure to loss for our unconsolidated VIEs is equal to our investment in these assets of $591.3 million.

Investment Securities

Our investment securities portfolio consists of: (i) an available-for-sale securities portfolio and a held-to-maturity securities portfolio, both of which represent interest-earning investment securities, and (ii) a non-marketable and other equity securities portfolio, which primarily represents investments managed as part of our funds management business as well as public equity securities held as a result of equity warrant assets exercised.

(1) As of March 31, 2019, we identified a total of 159 investments that were in unrealized loss positions, of which 151 investments totaling $5.6 billion with unrealized losses of $41.8 million have been in an impaired position for a period of time greater than 12 months. As of March 31, 2019, 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 March 31, 2019, 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.

The following table summarizes the fixed income securities, carried at fair value, classified as available-for-sale as of March 31, 2019 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.

(2) The carrying value represents investments in 212 and 213 funds (primarily venture capital funds) at March 31, 2019 and December 31, 2018, 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. We 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 investments. For each fund investment, 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 31^st for our March 31^st consolidated financial statements, adjusted for any contributions paid, distributions received from the investment, and significant fund transactions or market events during the reporting period.

(3) 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.

Loans, Allowance for Loan Losses and Allowance for Unfunded Credit Commitments

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.

The composition of loans, net of unearned income of $170 million and $173 million at March 31, 2019 and December 31, 2018, respectively, is presented in the following table:

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 full repayment of a criticized loan has been deemed improbable under the original contractual terms but full repayment remains probable overall, the loan is considered to be 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 2018 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.

The following table summarizes the credit quality indicators, broken out by portfolio segment and class of financing receivables as of March 31, 2019 and December 31, 2018:

Troubled Debt Restructurings

As of March 31, 2019, we had 19 TDRs with a total carrying value of $86.9 million where concessions have been granted to borrowers experiencing financial difficulties, in an attempt to maximize collection. There were $3.3 million of unfunded commitments available for funding to the clients associated with these TDRs as of March 31, 2019.

The following table summarizes our loans modified in TDRs, broken out by portfolio segment and class of financing receivables at March 31, 2019 and December 31, 2018:

(1) There were $2.2 million of partial charge-offs for the three months endedMarch 31, 2019 and no partial charge-offs during the three months endedMarch 31, 2018.

During the three months endedMarch 31, 2019 and 2018, all new TDRs of $5.7 million and $3.9 million, respectively, were modified through payment deferrals granted to our 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 months endedMarch 31, 2019 and 2018:

Life science/healthcare	5,000		—
Total TDRs modified within the previous 12 months that defaulted in the period	$	5,000	$	3,032

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 for TDRs was necessary to determine the allowance for loan losses as of March 31, 2019.

Leases

Leases [Abstract]

Leases

Leases

We have operating leases for our corporate offices, data centers and certain equipment utilized at those properties. We are obligated under a number of noncancelable operating leases for premises and equipment that expire at various dates, through 2030, and in most instances, include options to renew or extend at market rates and terms. Such leases may provide for periodic adjustments of rentals during the term of the lease based on changes in various economic indicators.

At the inception of the lease, the lease is evaluated to determine whether the lease will be accounted for as an operating or a finance lease. There were no significant assumptions or judgments required upon applying the new lease standard. Operating lease ROU assets and operating lease liabilities are included in our consolidated balance sheets. We have no leases that meet the definition of a finance lease under ASC 842 and our lessor accounting treatment for subleases is not material. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods.

Total recorded balances for the lease assets and liabilities are as follows:

(Dollars in thousands)	March 31, 2019
Assets:
Right-of-use assets - operating leases (1)	$	164,659
Liabilities:
Lease liabilities - operating leases (1)	205,167

(1) Included in these amounts are $24.4 million and $33.7 million of ROU assets and lease liabilities, respectively, attributable to the inclusion of SVB Leerink in our financial results at March 31, 2019.

The components of our lease cost and other information related to leases for the three months endedMarch 31, 2019 were as follows:

(Dollars in thousands)	Three months ended March 31, 2019

(1) The incremental borrowing rate used to calculate the lease liability was determined based on the facts and circumstances of the economic environment and the Company’s credit standing as of the effective date of ASC 842. Additionally, the total lease term and total lease payments were also considered in determining the rate. Based on these considerations the Company identified credit terms available under its existing credit lines which represent a collateralized borrowing rate that has varying credit terms that could be matched to total lease terms and total lease payments in ultimately determining the implied borrowing rate in each lease contract.

The following table presents our undiscounted future cash payments for our operating lease liabilities as of March 31, 2019:

Interest expense related to short-term borrowings and long-term debt was $10.2 million for the three months ended March 31, 2019 and $8.4 million for the three months endedMarch 31, 2018. The weighted average interest rate associated with our short-term borrowings was 2.62 percent as of December 31, 2018. There were no overnight short-term borrowings as of March 31, 2019.

Short-term Borrowings

We have certain facilities in place to enable us to access short-term borrowings on a secured and unsecured basis. Our secured facilities include collateral pledged to the FHLB of San Francisco and the discount window at the FRB (using both fixed income securities and loans as collateral). Our unsecured facility consists of our uncommitted federal funds lines. As of March 31, 2019, collateral pledged to the FHLB of San Francisco was comprised primarily of fixed income investment securities and loans and had a carrying value of $4.5 billion, of which $4.0 billion was available to support additional borrowings. As of March 31, 2019, collateral pledged to the discount window at the FRB was comprised of fixed income investment securities and had a carrying value of $0.9 billion, all of which was unused and available to support additional borrowings. Our total unused and available borrowing capacity for our uncommitted federal funds lines totaled $1.9 billion at March 31, 2019. Our total unused and available borrowing capacity under our master repurchase agreements with various financial institutions totaled $3.3 billion at March 31, 2019.

Derivative Financial Instruments

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

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, 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 on our variable-interest rate loan portfolio, we enter into interest rate swap contracts to hedge against future changes in interest rates by using hedging instruments to lock in future cash inflows that would otherwise be impacted by movements in the market interest rates. We designate these interest rate swap contracts as cash flow hedges that qualify for hedge accounting under ASC 815, Derivatives and Hedging ("ASC 815"), and record them in other assets and other liabilities. For qualifying cash flow hedges, changes in the fair value of the derivative are recorded in accumulated other comprehensive income and recognized in earnings as the hedged item affects earnings. Derivative amounts affecting earnings are recognized consistent with the classification of the hedged item in the line item "Loans" as part of interest income, a component of consolidated net income.

We assess hedge effectiveness under ASC 815 on a quarterly basis to ensure all hedges remain highly effective to ensure hedge accounting under ASC 815 can be applied. If the hedging relationship no longer exists or no longer qualifies as a hedge per ASC 815, any amounts remaining as gain or loss in accumulated other comprehensive income are reclassified into earnings in the line item "Loans" as part of interest income, a component of consolidated net income. As of March 31, 2019, no derivatives classified as hedges were terminated or were disqualified for hedge accounting. The maximum length of time over which the forecasted transactions are hedged is approximately five years.

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” 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” 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 2018 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.

The total notional or contractual amounts and fair value of our derivative financial instruments at March 31, 2019 and December 31, 2018 were as follows:

Gains on investment securities, net

Net gains on investment securities include both gains and losses from our non-marketable and other equity securities, which include public equity securities held as a result of exercised equity warrant assets, gains and losses from sales of our AFS debt securities portfolio, when applicable, and carried interest.

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, which include public equity securities held as a result of exercised equity warrant assets and 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.

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, and 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. Though infrequent, sales of debt securities in our AFS securities portfolio may result in net gains or losses and are conducted pursuant to the guidelines of our investment policy related to the management of our liquidity position and interest rate risk.

Gains on investment securities are recognized outside of the scope of ASC 606 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 endedMarch 31, 2019 and 2018 is as follows:

	Three months ended March 31,
(Dollars in thousands)	2019			2018

Total gains on investment securities, net	$	29,028		$	9,058

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 ASC 606 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 endedMarch 31, 2019 and 2018 is as follows:

	Three months ended March 31,
(Dollars in thousands)	2019			2018

Changes in fair value, net	16,238			10,186
Total net gains on equity warrant assets	$	21,305		$	19,191

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 ASC 606 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 endedMarch 31, 2019 and 2018 is as follows:

	Three months ended March 31,
(Dollars in thousands)	2019		2018
Foreign exchange fees by instrument type:
Spot contract commissions	$	35,029	$	31,202
Forward contract commissions	2,995		2,485
Option premium fees	24		140
Total foreign exchange fees	$	38,048	$	33,827

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.

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 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 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. A summary of client investment fees by instrument type for the three months endedMarch 31, 2019 and 2018 is as follows:

Unused commitment fees, minimum finance fees and unused line fees are recognized as earned on a monthly basis. Fees that qualify for syndication treatment are recognized at the completion of the syndicated loan deal for which the fees were received. Lending related fees are recognized outside of the scope of ASC 606 as it explicitly excludes noninterest income earned from our lending-related activities. A summary of lending related fees by instrument type for the three months endedMarch 31, 2019 and 2018 is as follows:

Letters of credit and standby letters of credit fees

Commercial and standby letters of credit represent conditional commitments issued by us on behalf of a client to guarantee the performance of the client to a third party when certain specified future events have occurred. 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 ASC 606 as it explicitly excludes noninterest income earned from our lending related activities.

Investment banking revenue

The Company earns investment banking revenue from clients for providing services related to securities underwriting, private placements and advisory services on strategic matters such as mergers and acquisitions. Underwriting fees are attributable to public and private offerings of equity and debt securities and are recognized at the point in time when the offering has been deemed to be completed by the lead manager of the underwriting group. Once the offering is completed, the performance obligation has been satisfied and the Company recognizes the applicable management fee as well the underwriting fee, net of consideration payable to customers. Estimated offering expenses are presented gross in our statements of income. The Company recognizes private placement fee revenue at the point in time when the private placement is completed, which is generally when the client accepts capital from the fund raise. Advisory fees from mergers and acquisitions engagements are generally recognized at the point in time when the related transaction is completed. Expenses are deferred only to the extent they are explicitly reimbursable by the client and the related revenue is recognized at a point in time. All other deal-related expenses are expensed as incurred. The Company has determined that it acts as principal in the majority of these transactions and therefore presents expenses gross within other operating expenses.

A summary of investment banking revenue by instrument type for the three months endedMarch 31, 2019 and 2018 is as follows:

	Three months ended March 31,
(Dollars in thousands)	2019		2018

Commissions

Commissions include commissions received from customers for the execution of agency-based brokerage transactions in listed and over-the-counter equities. The execution of each trade order represents a distinct performance obligation and the transaction price is fixed at the point in time or trade order execution. Trade execution is satisfied at the point in time that the customer has control of the asset and as such, fees are recorded on a trade date basis. Commissions for the three months endedMarch 31, 2019 were $14.1 million.

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 ASC 606.

Other service revenue 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.

A summary of other noninterest income by instrument type for the three months endedMarch 31, 2019 and 2018 is as follows:

The timing of revenue recognition may differ from the timing of cash settlements or invoicing to customers. We record a receivable when revenue is recognized prior to invoicing, 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, 2019 and 2018, changes in our contract assets, contract liabilities and receivables were not material. Additionally, revenues recognized during the three months ended March 31, 2019 and 2018 that were included in the corresponding contract liability balance at the beginning of the periods were not material.

Segment Reporting [Abstract]

Segment Reporting

Segment Reporting

We have four reportable segments for management reporting purposes: Global Commercial Bank, SVB Private Bank, SVB Capital and SVB Leerink. SVB Leerink is a new reportable segment and was created as a result of the acquisition of Leerink Holdings LLC effective January 4, 2019. 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 funded loans. 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 tax expense 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 four 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, trade finance, and other services. We broadly serve clients within the U.S., 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.

◦ SVBWine 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 products, 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-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.

• SVB Leerink is an investment bank specializing in the equity and convertible capital markets, mergers and acquisitions, equity research and sales and trading for growth and innovation-minded healthcare and life science companies and operates as a wholly-owned subsidiary of SVB Financial. SVB Leerink provides investment banking services across all subsectors of healthcare including: biotechnology, pharmaceuticals, medical devices, diagnostic and life science tools, healthcare services and digital health. SVB Leerink focuses on two primary lines of business: (i) investment banking focused on providing companies with capital-raising services, financial advice on mergers and acquisitions, sales and trading services and equity research, and (ii) sponsorship of private investment funds.

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

(1) Global Commercial Bank’s, SVB Capital’s and SVB Leerink'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 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 $4.9 million and $5.5 million for the three months ended March 31, 2019 and 2018, 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.

(6) Included in the total average assets for SVB Leerink is goodwill of $135.2 million for the three months ended March 31, 2019 related to the acquisition effective January 4, 2019.

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 March 31, 2019:

(Dollars in thousands)	SVBFG Capital Commitments		SVBFG Unfunded     Commitments		SVBFG Ownership   of each Fund (3)

Fair Value of Financial Instruments

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 on 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, foreign government debt 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-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.

Other equity 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. Certain sales restriction 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.

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.

Interest rate derivative and interest rate swap 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.

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:

Venture capital 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.

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.

The following fair value hierarchy table presents information about our assets and liabilities that are measured at fair value on a recurring basis as of March 31, 2019:

The following table presents quantitative information about the significant unobservable inputs used for certain of our Level 3 fair value measurements at March 31, 2019 and December 31, 2018. We have not included in this table our venture capital and private equity fund investments (fair value accounting) as we use net asset value per share (as obtained from the general partners of the investments) as a practical expedient to determine fair value.

(Dollars in thousands)	Fair value		Valuation Technique	Significant Unobservable Inputs	Weighted  Average

				Remaining life assumption (4)	45.0

(1) In determining the fair value of our 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 terminations and exercises. At March 31, 2019, the weighted average contractual remaining term was 6.1 years, compared to our estimated remaining life of 2.8 years. On a quarterly basis, a sensitivity analysis is performed on our remaining life assumption.

For the three months endedMarch 31, 2019 and 2018, 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 months endedMarch 31, 2019 and 2018 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.

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 December 31^st, for our March 31^st 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 March 31, 2019:

(Dollars in thousands)	Carrying Amount		Fair Value		Unfunded Commitments
Non-marketable securities (fair value accounting):
Venture capital and private equity fund investments (1)	$	303,418	$	303,418	$	12,540
Non-marketable securities (equity method accounting):
Venture capital and private equity fund investments (2)	148,096		148,096		12,801
Debt funds (2)	5,826		5,826		—
Other investments (2)	15,381		15,381		886
Total	$	472,721	$	472,721	$	26,227

(1) Venture capital and private equity fund investments within non-marketable securities (fair value accounting) include investments made by our managed funds of funds and one of our direct venture funds (consolidated VIEs) and investments in venture capital and private equity fund investments (unconsolidated VIEs). Collectively, these investments in venture capital and private equity funds are primarily in U.S. and global technology and life science/healthcare companies. Included in the fair value and unfunded commitments of fund investments under fair value accounting are $79.4 million and $4.1 million, respectively, attributable to noncontrolling interests. It is estimated that we will receive distributions from the fund investments overthe next 10 to 13 years, depending on the age of the funds and any potential extensions of terms of the funds.

(2) Venture capital and private equity fund investments, debt funds, and other fund investments within non-marketable securities (equity 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.

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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

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 diverse set 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 months endedMarch 31, 2019 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, 2018 (“2018 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 2018 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

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 based on 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) the 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 and Recent Accounting Pronouncements

Adoption of New Accounting Standards

In February 2016, the FASB issued a new accounting standard update (ASU 2016-02, Leases (Topic 842)), which requires for all operating leases the recognition of a right-of-use ("ROU") asset and a corresponding lease liability, in the statement of financial position. For short term leases (term of 12 months or less), a lessee is permitted to make an accounting election not to recognize lease assets and lease liabilities. The lease cost will be allocated over the lease term on a straight-line basis. There were further amendments, including practical expedients, with the issuance of ASU 2018-01, “Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842” in January 2018. In July 2018 the FASB issued ASU No. 2018-11, "Leases (Topic 842): Targeted Improvements", which provides us with the option to apply the new leasing standard to all open leases as of the adoption date, on a prospective basis.

On January 1, 2019, we adopted the new accounting standard ASU 2016-02, Leases (Topic 842) and all the related amendments ("new lease standard", "ASC 842" or "ASU 2016-02") utilizing the practical expedient to apply the new lease standard as of the January 1, 2019 on a prospective basis. We also elected the "package of expedients" and elected as an accounting policy to exclude recording ROU assets and lease liabilities for leases that meet the definition of short-term leases. In addition to excluding short-term leases, we have implemented an accounting policy in which non-lease components are not separated from lease components in the measurement of ROU assets and lease liabilities for all lease contracts. The "package of expedients" allowed us to continue to account for existing leases for which the commencement date is before January 1, 2019, in accordance with the previous guidance, Leases (Topic 840), throughout the lease term, including periods after adoption of the new guidance. We recognized $146 million in ROU assets and $178 million in lease liabilities as a result of applying the new lease standard as an adjustment to our opening consolidated balance sheet on January 1, 2019. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. See Note 9—"Leases" of the “Notes to Interim Consolidated Financial Statements (unaudited)” under Part I, Item 1 of this report for additional disclosures related to our leases.

In March 2017, the FASB issued ASU No. 2017-08, Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities, which amends the amortization period for certain purchased callable debt securities held at a premium. The ASU requires entities to amortize premiums on debt securities by the first call date when the securities have fixed and determinable call dates and prices. The scope of the ASU includes all accounting premiums, such as purchase premiums and cumulative fair value hedge adjustments. The ASU does not change the accounting for discounts, which continue to be recognized over the contractual life of a security. Adoption of the ASU is on a modified retrospective basis through a cumulative effect adjustment to retained earnings as of the beginning of the year of adoption. Adoption of the ASU primarily affected our HTM portfolio of callable state and municipal debt securities. On January 1, 2019, we adopted the ASU and recognized a net reduction to retained earnings of $583 thousand.

Recent Accounting Pronouncements

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 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 2018, the FASB issued a new accounting standard update (ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement). The ASU primarily modifies certain disclosures with respect to Level 3 fair value measurements. This guidance will be effective January 1, 2020, with early adoption permitted. This guidance will not have an impact on our consolidated financial position or results of operations, and we do not expect the adoption of this standard to have a material impact on the disclosures in our Notes to the Consolidated Financial Statements.

(1) As of March 31, 2019, we identified a total of 159 investments that were in unrealized loss positions, of which 151 investments totaling $5.6 billion with unrealized losses of $41.8 million have been in an impaired position for a period of time greater than 12 months. As of March 31, 2019, 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 March 31, 2019, 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.

Summary of Remaining Contractual Principal Maturities and Fully Taxable Equivalent Yields on Securities

The following table summarizes the fixed income securities, carried at fair value, classified as available-for-sale as of March 31, 2019 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.

(2) The carrying value represents investments in 212 and 213 funds (primarily venture capital funds) at March 31, 2019 and December 31, 2018, 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. We 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 investments. For each fund investment, 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 31^st for our March 31^st consolidated financial statements, adjusted for any contributions paid, distributions received from the investment, and significant fund transactions or market events during the reporting period.

(3) 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 endedMarch 31, 2019:

Leases [Abstract]

Schedule of Lease Assets and Liabilities

Total recorded balances for the lease assets and liabilities are as follows:

(Dollars in thousands)	March 31, 2019
Assets:
Right-of-use assets - operating leases (1)	$	164,659
Liabilities:
Lease liabilities - operating leases (1)	205,167

(1) Included in these amounts are $24.4 million and $33.7 million of ROU assets and lease liabilities, respectively, attributable to the inclusion of SVB Leerink in our financial results at March 31, 2019.

Lease Expense Components

The components of our lease cost and other information related to leases for the three months endedMarch 31, 2019 were as follows:

(Dollars in thousands)	Three months ended March 31, 2019
Operating lease cost	$	9,518
Short-term lease cost	263
Variable lease cost	846
Less: sublease income	(1,108		)
Total lease cost, net	$	9,519
Other information:
Weighted-average remaining term (in years) - operating leases	6.40
Weighted-average discount rate - operating leases (1)	3.18		%
Supplemental cash flows information:
Cash paid for operating leases	$	10,354

(1) The incremental borrowing rate used to calculate the lease liability was determined based on the facts and circumstances of the economic environment and the Company’s credit standing as of the effective date of ASC 842. Additionally, the total lease term and total lease payments were also considered in determining the rate. Based on these considerations the Company identified credit terms available under its existing credit lines which represent a collateralized borrowing rate that has varying credit terms that could be matched to total lease terms and total lease payments in ultimately determining the implied borrowing rate in each lease contract.

Lessee, Operating Lease, Liability, Maturity

The following table presents our undiscounted future cash payments for our operating lease liabilities as of March 31, 2019:

(1) Global Commercial Bank’s, SVB Capital’s and SVB Leerink'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 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 $4.9 million and $5.5 million for the three months ended March 31, 2019 and 2018, respectively.

Quantitative Information About Significant Unobservable Inputs

The following table presents quantitative information about the significant unobservable inputs used for certain of our Level 3 fair value measurements at March 31, 2019 and December 31, 2018. We have not included in this table our venture capital and private equity fund investments (fair value accounting) as we use net asset value per share (as obtained from the general partners of the investments) as a practical expedient to determine fair value.

(Dollars in thousands)	Fair value		Valuation Technique	Significant Unobservable Inputs	Weighted  Average
March 31, 2019:
Venture capital and private equity fund investments (fair value accounting)	$	1,035	Private company equity pricing	(1)	(1	)
Equity warrant assets (public portfolio)	6,505		Black-Scholes option pricing model	Volatility	54.2	%
				Risk-Free interest rate	2.3
				Sales restrictions discount (2)	15.3
Equity warrant assets (private portfolio)	150,244		Black-Scholes option pricing model	Volatility	38.6
				Risk-Free interest rate	2.2
				Marketability discount (3)	17.7
				Remaining life assumption (4)	45.0
December 31, 2018:
Venture capital and private equity fund investments (fair value accounting)	$	1,079	Private company equity pricing	(1)	(1	)
Equity warrant assets (public portfolio)	2,757		Black-Scholes option pricing model	Volatility	54.7	%
				Risk-Free interest rate	2.6
				Sales restrictions discount (2)	18.5
Equity warrant assets (private portfolio)	142,442		Black-Scholes option pricing model	Volatility	38.5
				Risk-Free interest rate	2.5
				Marketability discount (3)	17.7
				Remaining life assumption (4)	45.0

(1) In determining the fair value of our 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 terminations and exercises. At March 31, 2019, the weighted average contractual remaining term was 6.1 years, compared to our estimated remaining life of 2.8 years. On a quarterly basis, a sensitivity analysis is performed on our remaining life assumption.
