Accounting Policies [Abstract]
Nature of Business and Summary of Significant Accounting Policies	Nature of Business and Summary of Significant Accounting Policies Nature of Business The accompanying consolidated financial statements include the accounts of Silvergate Capital Corporation, a Maryland corporation and its wholly-owned subsidiary, Silvergate Bank (the “Bank”), collectively referred to as (the “Company” or “Silvergate”). The Bank was incorporated in 1987 and commenced business in 1988 under the California Financial Code as an industrial bank. In February 2009 the Bank converted its charter to a California commercial bank, which gave it the added authority to accept demand deposits. At the same time, the Company also became a registered bank holding company under the federal Bank Holding Company Act. The Bank became a member of the Federal Reserve System in December 2012. The Bank is subject to regulation by the California Department of Business Oversight (“DBO”), and the Federal Reserve Bank of San Francisco (“FRB”), and its deposits are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to applicable legal limits. On November 15, 2018, the Company and the Bank entered into a purchase and assumption agreement to sell the Bank’s retail branch located in San Marcos, California and business loan portfolio to HomeStreet Bank. The Company completed the sale in March 2019, which included the reduction of $115.4 million in loans and $74.5 million in deposits and resulted in a pre-tax gain on sale of $5.5 million . Financial Statement Preparation and Presentation The accompanying interim condensed consolidated financial statements have been prepared by the Company, without audit, in accordance with the instructions to the Quarterly Report on Form 10-Q, and Rule 10-01 of Regulation S-X promulgated by the United States Securities and Exchange Commission (the “SEC”) and, therefore, do not include all information and footnotes necessary for a fair presentation of its consolidated financial statements in accordance with accounting principles generally accepted in the United States (“GAAP”). In the opinion of management, the unaudited financial information for the interim periods presented reflects all adjustments, consisting of only normal and recurring adjustments, necessary for a fair statement of the Company’s condensed consolidated financial statements. These consolidated statements should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2019, included in the Company’s Annual Report on Form 10-K dated March 10, 2020. Operating results for interim periods are not necessarily indicative of operating results for an entire fiscal year. The consolidated financial statements include the accounts of the Company and all other entities in which it has a controlling financial interest. All significant intercompany accounts and transactions have been eliminated in consolidation. Unless the context requires otherwise, all references to the Company include its wholly owned subsidiaries. The accounting and reporting policies of the Company are based upon GAAP and conform to predominant practices within the financial services industry. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts and the disclosure of contingent amounts in the Company’s financial statements and the accompanying notes. We evaluate estimates on an ongoing basis including the economic impact of Coronavirus Disease 2019 (or “COVID-19”). Actual results could materially differ from those estimates. Recently issued accounting pronouncements not yet effective In June 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (or “ASU”) 2016-13, Financial Instruments-Credit Losses (Topic 326) to replace the incurred loss model with an expected loss model, which is referred to as the current expected credit loss (or “CECL”) model. The CECL model is applicable to the measurement of credit losses on financial assets measured at amortized cost, including loan receivables, held to maturity debt securities, and reinsurance receivables. It also applies to off-balance sheet credit exposures not accounted for as insurance (loan commitments, standby letters of credit, financial guarantees, and other similar instruments) and net investments in leases recognized by a lessor. These amendments were initially effective for fiscal years beginning after December 15, 2019 for SEC registrants and after December 15, 2020, for Public Business Entities, or PBEs. In November 2019, the FASB issued ASU 2019-10, Financial Instruments-Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates, which finalized the delay of the effective date for smaller reporting companies, such as the Company, to apply the standards related to CECL, until fiscal years beginning after December 15, 2022. For debt securities with other than temporary impairment (OTTI), the guidance will be applied prospectively and for existing purchased credit impaired (PCI) assets will be grandfathered and classified as purchased credit deteriorated (PCD) assets at the date of adoption. The asset will be grossed up for the allowance for expected credit losses for all PCD assets at the date of adoption and will continue to recognize the noncredit discount in interest income based on the yield such assets as of the adoption date. Subsequent changes in expected credit losses will be recorded through the allowance. For all other assets with the scope of CECL, the cumulative effect adjustment will be recognized in retained earnings as of the beginning of the first reporting period in which the guidance is effective. In November 2018, the FASB issued ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, which clarify that receivables arising from operating leases are not within the scope of Subtopic 326-20. Instead, impairment of receivables arising from operating leases should be accounted for in accordance with Topic 842, Leases. The Company formed a CECL implementation committee in 2018 which prepared a project plan to migrate towards the adoption date. As part of the project plan, the Company contracted a third-party vendor to assist in the application and analysis of ASU 2016-13 as well as a third-party vendor to perform an independent model validation. As part of this process, the Company has determined preliminary loan pool segmentation under CECL, as well as evaluated the key economic loss drivers for each segment. The Company operationalized an initial CECL model during the second quarter of 2019 and is running this preliminary CECL model alongside the existing incurred loss methodology. The Company intends to continue to refine and run the model until the date of adoption. The Company continues to evaluate the effects of ASU 2016-13 on its financial statements and disclosures and whether to early adopt the guidance. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (or “ASU 2020-04”), which provides temporary, optional guidance to ease the potential burden in accounting for, or recognizing the effects of, the transition away from the London Interbank Offered Rate (or “LIBOR”) or other interbank offered rate (reference rates) on financial reporting, which currently is expected to be discontinued by the end of 2021. To help with the transition to new reference rates, the ASU provides optional expedients and exceptions for applying GAAP to affected contract modifications and hedge accounting relationships. The guidance is applicable only to contracts or hedge accounting relationships that reference LIBOR or another reference rate expected to be discontinued. The expedients and exceptions in this update are available to all entities starting March 12, 2020 through December 31, 2022. The Company is evaluating the impact that ASU 2020-04 will have on those financial assets where LIBOR is used as an index rate.

At June 30, 2020 , the total fair value of securities issued by four individual issuers, other than the U.S. Government and its agencies, in an amount greater than 10% of shareholders’ equity was $158.6 million . Securities with unrealized losses as of the dates indicated, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, are as follows: Available-for-sale securities Less than 12 Months 12 Months or More Total Fair Value Unrealized Fair Value Unrealized Fair Value Unrealized (Dollars in thousands) June 30, 2020 Residential mortgage-backed securities: Government agency mortgage-backed securities $ 409 $ (1 ) $ — $ — $ 409 $ (1 ) Government agency collateralized mortgage obligation 139,254 (174 ) 62,559 (137 ) 201,813 (311 ) Private-label collateralized mortgage obligation 1,744 (43 ) 8,890 (3,407 ) 10,634 (3,450 ) Asset backed securities: Government sponsored student loan pools — — 241,216 (12,744 ) 241,216 (12,744 ) $ 141,407 $ (218 ) $ 312,665 $ (16,288 ) $ 454,072 $ (16,506 ) Available-for-sale securities Less than 12 Months 12 Months or More Total Fair Value Unrealized Fair Value Unrealized Fair Value Unrealized (Dollars in thousands) December 31, 2019 Residential mortgage-backed securities: Government agency collateralized mortgage obligation $ 143,633 $ (785 ) $ 15,794 $ (52 ) $ 159,427 $ (837 ) Private-label collateralized mortgage obligation 59 (1 ) 15,168 (197 ) 15,227 (198 ) Commercial mortgage-backed securities: Private-label collateralized mortgage obligation 13,142 (177 ) — — 13,142 (177 ) Asset backed securities: Government sponsored student loan pools 62,938 (1,317 ) 188,593 (5,174 ) 251,531 (6,491 ) $ 219,772 $ (2,280 ) $ 219,555 $ (5,423 ) $ 439,327 $ (7,703 ) As indicated in the tables above, as of June 30, 2020 , the Company’s investment securities had gross unrealized losses totaling approximately $16.5 million , compared to approximately $7.7 million at December 31, 2019 . The Company analyzed all of its securities with an unrealized loss position. For each security, the Company analyzed the credit quality and performed a projected cash flow analysis. In analyzing the credit quality, management may consider whether the securities are issued by the federal government, its agencies or its sponsored entities, or non-governmental entities, whether downgrades by bond rating agencies have occurred, and if credit quality has deteriorated. When performing a cash flow analysis the Company uses models that project prepayments, default rates, and loss severities on the collateral supporting the security, based on underlying loan level borrower and loan characteristics and interest rate assumptions. In addition, the Company has contracted with third party companies to perform independent cash flow analyses of its securities portfolio as needed. The unrealized losses on private-label collateralized mortgage obligations are due primarily to increased credit spreads as of June 30, 2020. The Company has an adequate amount of credit enhancement to cover any expected losses at this time. Based on these analyses and reviews conducted by the Company, and assisted by independent third parties, the Company determined that none of its securities required an other-than-temporary impairment charge at June 30, 2020 or December 31, 2019 . Management continues to expect to recover the adjusted amortized cost basis of these bonds. As of June 30, 2020 , the Company had 33 securities whose estimated fair value declined 3.51% from the Company’s amortized cost; at December 31, 2019 , the Company had 33 securities whose estimated fair value declined 1.72% from the Company’s amortized cost. The increase in percentage of unrealized losses is related to market liquidity concerns associated with COVID-19, which persisted though the second quarter of 2020, and widened credit spreads on securities and changes in market interest rates since the purchase dates. Unrecognized losses associated with liquidity concerns as a result of COVID-19 are not expected to remain constant in the future, however, unrecognized losses will continue to vary with general market interest rate fluctuations. Fair values are expected to recover as the securities approach their respective maturity dates and management believes it is not more likely than not it will be required to sell before recovery of the amortized cost basis. For the three months ended June 30, 2020 the Company received $202.3 million in proceeds and recognized a $3.5 million gain and $0.9 million loss on sales of available-for-sale securities. For the six months ended June 30, 2020 the Company received $216.4 million in proceeds and recognized a $4.7 million gain and $0.9 million loss on sales of available-for-sale securities. There were no sales and calls of securities for the three and six months ended June 30, 2019 . There were no credit losses associated with our securities portfolio recognized in earnings for the three and six months ended June 30, 2020 and 2019 .

Receivables [Abstract]
Loans	Loans The following disclosure reports the Company’s loan portfolio segments and classes. Segments are groupings of similar loans at a level in which the Company has adopted systematic methods of documentation for determining its allowance for loan and credit losses. Classes are a disaggregation of the portfolio segments. The Company’s loan portfolio segments are: Real estate loans. Real estate includes loans for which the Company holds one-to-four family, multi-family, commercial and construction real property as collateral. Commercial real estate lending activity is typically restricted to owner-occupied properties or to investor properties that are owned by customers with a current banking relationship. The primary risks of real estate mortgage loans include the borrower’s inability to pay, material decreases in the value of the real estate that is being held as collateral and significant increases in interest rates, which may make the real estate mortgage loan unprofitable. Real estate loans also may be adversely affected by conditions in the real estate markets or in the general economy. Commercial and industrial . Commercial and industrial loans consist of loans and lines of credit to small and medium-sized businesses in a wide variety of industries, including distributors, manufacturers, software developers, business services companies and independent finance companies. Commercial and industrial loans are generally collateralized by accounts receivable, inventory, equipment, loan and lease receivables, and other commercial assets, and may be supported by other credit enhancements such as personal guarantees. Risk may arise from differences between expected and actual cash flows and/or liquidity levels of the borrowers, as well as the type of collateral securing these loans and the reliability of the conversion thereof to cash. Since the March 2019 sale of the business loan portfolio, commercial and industrial loans consist primarily of asset based loans. In the first quarter of 2020, the Company began offering a new pilot product called SEN Leverage, which will allow Silvergate customers to obtain U.S. dollar loans collateralized by bitcoin held at select digital currency exchanges or custodians that are also Silvergate customers. The Company plans to expand this offering in the latter part of 2020. The outstanding balance of SEN Leverage loans was $20.0 million as of June 30, 2020 . Consumer and other. Consumer loans consist of consumer loans and other loans secured by personal property. Reverse mortgage. From 2012 to 2014, the Company purchased home equity conversion mortgage (“HECM”) loans (also known as reverse mortgage loans) which are a special type of home loan, for homeowners aged 62 years or older, that requires no monthly mortgage payments. Reverse mortgage loan insurance is provided by the U.S. Federal Housing Administration through the HECM program which protects lenders from losses due to non-repayment of the loans. In mid-2014, the Company ceased purchases of reverse mortgage loans and, began selling its remaining loans in the secondary market. Mortgage warehouse. The Company’s mortgage warehouse lending division provides short-term interim funding for single-family residential mortgage loans originated by mortgage bankers or other lenders pending the sale of such loans in the secondary market. The Company’s risk is mitigated by comprehensive policies, procedures, and controls governing this activity, partial loan funding by the originating lender, guaranties or additional monies pledged to the Company as security, and the short holding period of funded loans on the Company’s balance sheet. In addition, the loss rates of this portfolio have historically been minimal, and these loans are all subject to written purchase commitments from takeout investors or are hedged. The Company’s mortgage warehouse loans may either be held-for-investment or held-for-sale depending on the underlying contract. The Company sold approximately $20.2 million and $36.8 million of loans to participants during the three months ended June 30, 2020 and 2019 , respectively. The Company sold approximately $41.9 million and $100.6 million of loans to participants during the six months ended June 30, 2020 and 2019 , respectively. At June 30, 2020 and December 31, 2019 , gross mortgage warehouse loans were approximately $477.1 million and $405.0 million , respectively. A summary of loans as of the periods presented are as follows: June 30, December 31, (Dollars in thousands) Real estate loans: One-to-four family $ 216,038 $ 193,367 Multi-family 72,007 81,233 Commercial 316,815 331,052 Construction 10,822 7,213 Commercial and industrial 24,707 14,440 Consumer and other 243 122 Reverse mortgage 1,309 1,415 Mortgage warehouse 155,308 39,247 Total gross loans held-for-investment 797,249 668,089 Deferred fees, net 3,062 2,724 Total loans held-for-investment 800,311 670,813 Allowance for loan losses (6,763 ) (6,191 ) Total loans held-for-investment, net $ 793,548 $ 664,622 Total loans held-for-sale (1) $ 321,835 $ 375,922 ________________________ (1) Loans held-for-sale included $321.8 million and $365.8 million of mortgage warehouse loans at June 30, 2020 and December 31, 2019 , respectively. At June 30, 2020 and December 31, 2019 , approximately $617.0 million and $614.3 million , respectively, of the Company’s loan portfolio were collateralized by various forms of real estate. A significant percentage of such loans are collateralized by properties located in California ( 74.1% and 64.8% as of June 30, 2020 and December 31, 2019 , respectively) and Arizona ( 6.5% and 10.2% as of June 30, 2020 and December 31, 2019 , respectively) with no other state greater than 5%. The Company attempts to address and mitigate concentrations of credit risk by making loans that are diversified by collateral type, placing limits on the amounts of various categories of loans relative to total Company capital, and conducting quarterly reviews of its portfolio by collateral type, geography, and other characteristics. While management believes that the collateral presently securing its portfolio and the recorded allowance for loan losses are adequate to absorb potential losses, there can be no assurances that significant deterioration in the California and Arizona real estate markets would not expose the Company to significantly greater credit risk. Recorded investment in loans excludes accrued interest receivable, loan origination fees, net and unamortized premium or discount, net due to immateriality. Accrued interest on loans held-for-investment totaled approximately $2.6 million and $2.2 million and deferred fees totaled approximately $3.1 million and $2.7 million at June 30, 2020 and December 31, 2019 , respectively. Allowance for Loan Losses During the three and six months ended June 30, 2020, the Company recorded a provision for loan losses of $0.2 million and $0.6 million , respectively, and t he ratio of the allowance for loan losses to gross loans held-for-investment at June 30, 2020 was 0.85% . The level of the allowance was based on modest increases in loan portfolio balances, Silvergate’s historically strong credit quality and minimal loan charge-offs, and the low to moderate loan-to-value margins in the Company's commercial, multi-family and one-to-four family real estate loans, as evidenced by weighted average loan-to-value ratios, based on last required appraisal value, in the low- to mid-50% range as of June 30, 2020. Although there is significant uncertainty in the current economic environment due to the impact of the COVID-19 pandemic, the Company believes the relatively low to moderate loan-to-value ratios provides a lower probability of loss in the event of defaults in the Company’s loan portfolio. The Company will continue to monitor trends in its portfolio segments for any known or probable adverse conditions with an emphasis on retail and hospitality loans within the commercial real estate loan portfolio. As of June 30, 2020, the Company enhanced its qualitative adjustment framework within the calculation of the allowance for loan losses to ensure consistency in the calculation. The change provided a structured framework using Company and peer historical data covering a full credit cycle to determine the range of potential loss for each qualitative adjustment. The overall change was not material to the overall allowance, however within loan segments the allowance was reallocated based on the weighted qualitative adjustment specific for each loan segment. The following tables present the allocation of the allowance for loan losses, as well as the activity in the allowance by loan class, and recorded investment in loans held-for-investment as of and for

In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. The Company has granted a concession when, as a result of the restructuring, it does not expect to collect all amounts due or within the time periods originally due under the original contract, including one or a combination of the following: a reduction of the stated interest rate of the loan; an extension of the maturity date at a stated rate of interest lower than the current market rate for new debt with similar risk; or a temporary forbearance with regard to the payment of principal or interest. All troubled debt restructurings are reviewed for potential impairment. Generally, a nonaccrual loan that is restructured remains on nonaccrual status for a minimum period of six months to demonstrate that the borrower can perform under the restructured terms. If the borrower’s performance under the new terms is not reasonably assured, the loan remains classified as a nonaccrual loan. Loans classified as TDRs are reported as impaired loans. As of June 30, 2020 and December 31, 2019 , the Company had a recorded investment in TDR’s of $1.6 million and $1.8 million , respectively. The Company has not allocated any amount of specific allowance for those loans at June 30, 2020 and December 31, 2019 . The Company has not committed to lend additional amounts to these TDRs. No loans were modified as TDRs during the three and six months ended June 30, 2020 . Modifications of loans classified as TDRs during the periods presented, are as follows: Three and Six Months Ended June 30, 2019 Number of Pre- Post- (Dollars in thousands) Troubled debt restructurings: Real estate loans: One-to-four family 2 $ 1,018 $ 1,114 Commercial and industrial 1 494 494 3 1,512 1,608 The TDR’s described above had no impact the allowance for loan losses and charge-offs during the three and six months ended June 30, 2019 . A loan is considered to be in payment default once it is 30 days contractually past due under the modified terms. There were no loans modified as TDRs for which there was a payment default within twelve months during the three and six months ended June 30, 2020 or 2019 . There was no provision for loan loss or charge-offs for TDR’s that subsequently defaulted during the three and six months ended June 30, 2020 or 2019 . COVID-19 Related Modifications In March 2020, various regulatory agencies, including the Board of Governors of the Federal Reserve System and the Federal Deposit Insurance Corporation, (“the agencies”) issued an interagency statement on loan modifications for financial institutions working with customers affected by the Coronavirus. The interagency statement was effective immediately and impacted accounting for loan modifications. Under Accounting Standards Codification 310-40, “Receivables—Troubled Debt Restructurings by Creditors” a restructuring of debt constitutes a TDR if the creditor, for economic or legal reasons related to the debtor’s financial difficulties, grants a concession to the debtor that it would not otherwise consider. The agencies confirmed with the staff of the FASB that short-term modifications made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief, are not to be considered TDRs. This includes short-term (e.g., six months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are insignificant. Loans qualifying for these modifications will not be required to be reported as delinquent, nonaccrual, impaired or criticized solely as a result of a COVID-19 loan modification for the months of payment deferrals. Borrowers considered current are those that are less than 30 days past due on their modified contractual payments. A revised statement issued in April 2020, further clarified the interaction between the interagency statement and the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) that was signed into law in March 2020. The Company elected to adopt these provisions of the CARES Act for the temporary modifications described above. In April 2020, the Company implemented a short-term loan modification program for customers impacted financially by the COVID-19 pandemic to provide temporary relief to certain borrowers who meet the program’s qualifications. The program was offered to borrowers to modify their existing loans to temporarily defer principal and/or interest payments for a specified period of time, extend loan maturity dates and/or waive certain loan covenants. Deferred payments may be extended for continued hardship but are not to exceed a total of six months. The majority of short-term loan modifications for commercial real estate loan borrowers consist of deferred payments which may include principal, interest and escrow. Deferred interest is capitalized to the loan balance and deferred principal is added to the maturity or payoff date. For one-to-four family loans, the majority of short-term modifications consist of deferring full monthly payment of principal, interest and escrow, with deferred payments due at maturity or payoff of the loan. During the six months ended June 30, 2020, the Company modified 49 loans representing $136.8 million in loan balances, or 17% , of total gross loans held-for-investment as of June 30, 2020. All loans modified under these programs are maintained on full accrual status during the deferral period. No specific loan loss reserve allocation was deemed necessary for these modified loans. None of the modified loans met the criteria of a TDR under the CARES Act or the related interagency statement. Loans modified that were not classified as TDRs during the period presented, are as follows: Six Months Ended June 30, 2020 Number of Loan Balance At Period End (Dollars in thousands) COVID-19 related modifications: Real estate loans: One-to-four family 19 $ 11,970 Commercial 28 123,499 Commercial and industrial 2 1,373 Total COVID-19 related modifications 49 $ 136,842 Credit Quality Indicators The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, collateral adequacy, credit documentation, and current economic trends, among other factors. This analysis typically includes larger, nonhomogeneous loans such as commercial real estate and commercial and industrial loans. This analysis is performed on an ongoing basis as new information is obtained. The Company uses the following definitions for risk ratings: Pass : Loans in all classes that are not adversely rated, are contractually current as to principal and interest, and are otherwise in compliance with the contractual terms of the loan agreement. Management believes that there is a low likelihood of loss related to those loans that are considered pass. Special mention : Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date. Substandard : Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Doubtful : Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Loss : Credits rated as loss are charged-off. Management has no expectation of the recovery of any payments in respect of credits rated as loss. The following tables present by portfolio class the Company’s internal risk grading system as well as certain other information concerning the credit quality of the Company’s recorded investment in loans held-for-investment as of the periods presented. No assets were classified as loss or doubtful during the periods presented.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative and Hedging Activities	Derivative and Hedging Activities The Company is exposed to certain risks relating to its ongoing business operations. The Company utilizes interest rate derivatives as part of its asset liability management strategy to help manage its interest rate risk position. The notional amount of the derivative does not represent amounts exchanged by the parties. The amount exchanged is determined by reference to the notional amount and the other terms of the individual derivative agreements. In accordance with accounting guidance, changes in the fair value of derivatives designated and that qualify as cash flow hedges are initially recorded in other comprehensive income (“OCI”), reclassified into earnings in the same period or periods during which the hedged transaction affects earnings and is presented in the same income statement line item as the earnings effect of the hedged item. The Company assesses the effectiveness of each hedging relationship by comparing the changes in cash flows of the derivative hedging instrument with the changes in cash flows of the designated hedged transactions. The initial fair value of hedge components excluded from the assessment of effectiveness is recognized in the statement of financial condition under a systematic and rational method over the life of the hedging instrument and is presented in the same income statement line item as the earnings effect of the hedged item. Any difference between the change in the fair value of the hedge components excluded from the assessment of effectiveness and the amounts recognized in earnings is recorded as a component of other comprehensive income. For a fair value hedge, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item, are recognized in current earnings as fair values change. The changes in fair value of the hedged item is recorded as a basis adjustment to the hedged assets or liabilities. The amount included as basis adjustments would be reclassified to current earnings on a straight-line basis over the original life of the hedged item should the hedges no longer be considered effective. Interest rate swap. In 2020, the Company entered into two pay-fixed/receive floating rate interest rate swaps (the “Swap Agreements”) for a notional amount of $14.3 million that were designated as fair value hedges of certain available-for-sale securities. The Swap Agreements were determined to be fully effective during the periods presented and therefore no amount of ineffectiveness has been included in net income. The Swap Agreements are based on three-month LIBOR and expire in 2030 and 2031. The Company expects the Swap Agreements to remain effective during the remaining term of the Swap Agreements. Interest rate floor. In 2019, the Company entered into 20 interest rate floor agreements (the "Floor Agreements") for a total notional amount of $400.0 million to hedge cash flow receipts on cash and securities or loans, if needed. The original Floor Agreements expire on various dates in April 2024 and July 2029. The Company utilizes one-month LIBOR and three-month LIBOR interest rate floors as hedges against adverse changes in cash flows on the designated cash, securities or loans attributable to fluctuations in the federal funds rate or three-month LIBOR below 2.50% or 2.25% , as applicable. The Floor Agreements were determined to be fully effective during all periods presented and, as such, no amount of ineffectiveness has been included in net income. The upfront fee paid to the counterparty in entering into these Floor Agreements was approximately $20.8 million . During the three months ended March 31, 2020, the Company sold $200.0 million of its total $400.0 million notional amount of interest rate floors for $13.0 million , which resulted in a net gain of $8.4 million , to be recognized over the weighted average remaining term of 4.1 years. The remaining agreements are one-month LIBOR floors with a strike price of 2.25% and expire in July 2029. Interest rate cap. In 2012, the Company entered into a $12.5 million and a $3.0 million notional forward interest rate cap agreement (the “Cap Agreements”) to hedge its variable rate subordinated debentures. The Cap Agreements expire July 25, 2022 and March 15, 2022, respectively. The Company utilizes interest rate caps as hedges against adverse changes in cash flows on the designated preferred trusts attributable to fluctuations in three-month LIBOR beyond 0.50% for the $3.0 million subordinated debenture and six-month LIBOR beyond 0.75% for the $12.5 million subordinated debenture. The Cap Agreements were determined to be fully effective during all periods presented and, as such, no amount of ineffectiveness has been included in net income. The upfront fee paid to the counterparty in entering into these Cap Agreements was approximately $2.5 million .

The increase was primarily related to higher net income. The effective tax rates for the three months ended June 30, 2020 and 2019 were 25.0% and 24.7% , respectively. The Company’s effective tax rate for the three months ended June 30, 2020 benefited from tax-exempt income earned on certain municipal bonds that were purchased beginning in late March 2020. The effective tax rate for the three months ended June 30, 2019 benefited from the recognition of tax benefits, including excess benefit from stock-based compensation. Income tax expense was $3.6 million for the six months ended June 30, 2020 compared to $5.7 million for the six months ended June 30, 2019 . The decrease was primarily related to reduced pre-tax income for the six months ended June 30, 2020 when compared to the six months ended June 30, 2019 . The effective tax rates for the six months ended June 30, 2020 and 2019 were 26.7% and 28.1% , respectively. The decrease in the Company’s effective tax rate was primarily related to tax-exempt income earned on certain municipal bonds. The deferred tax liability balance as of June 30, 2020 was $11.8 million compared to $0.4 million as of December 31, 2019 . The primary change in balance was due to the increase in unrealized gains on derivative assets and available-for-sale securities portfolio.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Off-Balance Sheet Items In the normal course of business, the Company enters into various transactions, which, in accordance with GAAP, are not included in the consolidated statements of financial condition. The Company enters into these transactions to meet the financing needs of its customers. These transactions include commitments to extend credit and issue letters of credit, which involve, to varying degrees, elements of credit risk and interest rate risk exceeding the amounts recognized on the consolidated statements of financial condition. The Company’s exposure to credit loss is represented by the contractual amounts of these commitments. The same credit policies and procedures are used in making these commitments as for on-balance sheet instruments. The Company is not aware of any accounting loss to be incurred by funding these commitments, however, an allowance for off-balance sheet credit risk is recorded in other liabilities on the statements of financial condition. The allowance for these commitments amounted to approximately $0.1 million as of June 30, 2020 and December 31, 2019 , respectively. The Company’s commitments associated with outstanding letters of credit and commitments to extend credit expiring by period as of the date indicated are summarized below. Since commitments associated with letters of credit and commitments to extend credit may expire unused, the amounts shown do not necessarily reflect the actual future cash funding requirements. June 30, December 31, (Dollars in thousands) Unfunded lines of credit $ 45,458 $ 47,433 Letters of credit 540 655 Total credit extension commitments $ 45,998 $ 48,088 Unfunded lines of credit represent unused credit facilities to the Company’s current borrowers that represent no change in credit risk that exist in the Company’s portfolio. Lines of credit generally have variable interest rates. Letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. In the event of nonperformance by the customer in accordance with the terms of the agreement with the third party, the Company would be required to fund the commitment. The maximum potential amount of future payments the Company could be required to make is represented by the contractual amount of the commitment. If the commitment is funded, the Company would be entitled to seek recovery from the client from the underlying collateral, which can include commercial real estate, physical plant and property, inventory, receivables, cash and/or marketable securities. The Company’s policies generally require that letter of credit arrangements contain security and debt covenants like those contained in loan agreements and our credit risk associated with issuing letters of credit is essentially the same as the risk involved in extending loan facilities to customers. The Company minimizes its exposure to loss under letters of credit and credit commitments by subjecting them to the same credit approval and monitoring procedures used for on-balance sheet instruments. The effect on the Company’s revenue, expenses, cash flows and liquidity of the unused portions of these letters of credit commitments cannot be precisely predicted because there is no guarantee that the lines of credit will be used. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract, for a specific purpose. Commitments generally have variable interest rates, fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts disclosed above do not necessarily represent future cash requirements. The Company evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained if deemed necessary by the Company is based on management’s credit evaluation of the customer. Litigation The Company is involved in various matters of litigation which have arisen in the ordinary course of its business. In the opinion of management, the disposition of such pending litigation will not have a material adverse effect on the Company’s financial statements.

Share-based Payment Arrangement [Abstract]
Stock-based Compensation	Stock-based Compensation In June 2018, the Company adopted the 2018 Equity Compensation Plan, or 2018 Plan, that permits the Compensation Committee, in its sole discretion, to grant various forms of incentive awards. Under the 2018 Plan, the Compensation Committee has the power to grant stock options, stock appreciation rights, or SARs, restricted stock and restricted stock units. The number of shares that may be issued pursuant to awards under the 2018 Plan is 1,596,753 . In 2010, the Company adopted an equity compensation plan, or 2010 Plan, that provides for the grant of stock options to employees, directors, and other persons referred to in Rule 701 under the U.S. Securities Act of 1933. The number of shares that may be issued pursuant to awards under the 2010 Plan is 730,784 . The Compensation Committee of the Company’s Board of Directors is responsible for administrating the 2010 Plan and determining the terms of all awards under it, including their vesting, except that in the case of a change in control of the Company all options granted under the 2010 Plan shall become 100% vested. As of June 30, 2020 , there are no shares available for issuance under the 2010 Plan. In accordance with authoritative guidance for stock-based compensation, compensation expense is recognized only for those shares expected to vest, based on the Company’s historical experience and future expectations. The Company has elected a policy of estimating expected forfeitures. Total stock-based compensation expense was $0.2 million and $30,000 for the three months ended June 30, 2020 and 2019 , respectively.

Regulatory Capital	Jun. 30, 2020
Banking and Thrift [Abstract]
Regulatory Capital	Regulatory Capital Banks and bank holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action. The final rules implementing Basel Committee on Banking Supervision’s capital guidelines for U.S. banks (Basel III rules) became effective for the Company on January 1, 2015 with full compliance with all of the requirements being phased in over a multi-year schedule, and fully phased in by January 1, 2019. Under the Basel III rules, the Company must hold a capital conservation buffer above the adequately capitalized risk-based capital ratios. As of January 1, 2019, the capital conservation buffer had fully phased in to 2.50%. Management believes, as of June 30, 2020 , the Company and the Bank meet all capital adequacy requirements to which they are subject. Prompt corrective action regulations provide five classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. For the periods presented, the most recent regulatory notifications categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the institution’s category. Actual capital amounts and ratios for the Company (assuming minimum capital adequacy ratios were applicable to the Company) and the Bank as of June 30, 2020 and December 31, 2019 , are presented in the following tables: Actual Minimum capital To be well Amount Ratio Amount Ratio Amount Ratio (Dollars in thousands) June 30, 2020 The Company Tier 1 leverage ratio $ 250,335 11.57 % $ 86,543 4.00 % N/A N/A Common equity tier 1 capital ratio 234,835 23.32 % 45,317 4.50 % N/A N/A Tier 1 risk-based capital ratio 250,335 24.86 % 60,423 6.00 % N/A N/A Total risk-based capital ratio 257,213 25.54 % 80,564 8.00 % N/A N/A The Bank Tier 1 leverage ratio 236,281 10.92 % 86,519 4.00 % $ 108,149 5.00 % Common equity tier 1 capital ratio 236,281 23.48 % 45,279 4.50 % 65,404 6.50 % Tier 1 risk-based capital ratio 236,281 23.48 % 60,373 6.00 % 80,497 8.00 % Total risk-based capital ratio 243,159 24.17 % 80,497 8.00 % 100,621 10.00 % Actual Minimum capital To be well Amount Ratio Amount Ratio Amount Ratio (Dollars in thousands) December 31, 2019 The Company Tier 1 leverage ratio $ 240,135 11.23 % $ 85,501 4.00 % N/A N/A Common equity tier 1 capital ratio 224,635 24.52 % 41,233 4.50 % N/A N/A Tier 1 risk-based capital ratio 240,135 26.21 % 54,978 6.00 % N/A N/A Total risk-based capital ratio 246,447 26.90 % 73,304 8.00 % N/A N/A The Bank Tier 1 leverage ratio 224,605 10.52 % 85,399 4.00 % $ 106,749 5.00 % Common equity tier 1 capital ratio 224,605 24.55 % 41,163 4.50 % 59,458 6.50 % Tier 1 risk-based capital ratio 224,605 24.55 % 54,884 6.00 % 73,179 8.00 % Total risk-based capital ratio 230,917 25.24 % 73,179 8.00 % 91,474 10.00 % The Bank is restricted as to the amount of dividends that it can pay to the Company. Dividends declared in excess of the lesser of the Bank’s undivided profits or the Bank’s net income for its last three fiscal years less the amount of any distribution made to the Bank’s shareholders during the same period must be approved by the California DBO. Also, the Bank may not pay dividends that would result in capital levels being reduced below the minimum requirements shown above.

Fair Value

Fair Value	Jun. 30, 2020
Fair Value Disclosures [Abstract]
Fair Value	Fair Value Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. This standard’s fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value: Level 1— Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2— Significant observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3— Significant unobservable inputs that reflect a Company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. Financial Instruments Required To Be Carried At Fair Value The following is a description of valuation methodologies used for assets and liabilities recorded at fair value: Securities available-for-sale . The fair values of securities available-for-sale are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1) or matrix pricing, which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted prices for specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2). Derivatives . The Company’s derivative assets and liabilities are carried at fair value as required by GAAP. The estimated fair values of the derivative assets and liabilities are based on current market prices for similar instruments. Given the meaningful level of secondary market activity for derivative contracts, active pricing is available for similar assets and accordingly, the Company classifies its derivative assets and liabilities as Level 2. Impaired loans (collateral-dependent) . The Company does not record impaired loans at fair value on a recurring basis. However, from time to time, fair value adjustments are recorded on these loans to reflect (1) partial write-downs, through charge-offs or specific allowances, that are based on the current appraised or market-quoted value of the underlying collateral or (2) the full charge-off of the loan carrying value. In some cases, the properties for which market quotes or appraised values have been obtained are located in areas where comparable sales data is limited, outdated, or unavailable. Fair value estimates for collateral-dependent impaired loans are obtained from real estate brokers or other third-party consultants. These appraisals may utilize a single valuation approach or a combination of approaches, which generally include various Level 3 inputs. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available and such adjustments are typically significant. Appraisals may be adjusted by management for qualitative factors such as economic factors and estimated liquidation expenses. The range of these possible adjustments may vary. Impaired loans presented in the table below as of the periods presented include impaired loans with specific allowances as well as impaired loans that have been partially charged-off. Other real estate owned . Fair value estimates for foreclosed real estate are obtained from real estate brokers or other third-party consultants (Level 3). When a current appraised value is not available or management determines the fair value of the collateral is further impaired below the appraised value as a result of known changes in the market or the collateral and there is no observable market price, such valuation inputs result in a fair value measurement that is categorized as a Level 3 measurement. To the extent a negotiated sales price or reduced listing price represents a significant discount to an observable market price, such valuation input would result in a fair value measurement that is also considered a Level 3 measurement. The following tables provide the hierarchy and fair value for each class of assets and liabilities measured at fair value at June 30, 2020 and December 31, 2019 . As of June 30, 2020 and December 31, 2019 , assets and liabilities measured at fair value on a recurring basis are as follows: Fair Value Measurements Using Quoted Prices Significant Other Significant Level 1 Level 2 Level 3 Total (Dollars in thousands) June 30, 2020 Assets Securities available-for-sale $ — $ 951,094 $ — $ 951,094 Derivative assets — 35,770 — 35,770 $ — $ 986,864 $ — $ 986,864 Fair Value Measurements Using Quoted Prices Significant Other Significant Level 1 Level 2 Level 3 Total (Dollars in thousands) December 31, 2019 Assets Securities available-for-sale $ — $ 897,766 $ — $ 897,766 Derivative assets — 23,440 — 23,440 $ — $ 921,206 $ — $ 921,206 As of June 30, 2020 and December 31, 2019 , assets measured at fair value on a non-recurring basis are summarized as follows: Fair Value Measurements Using Quoted Prices Significant Other Significant Level 1 Level 2 Level 3 Total (Dollars in thousands) June 30, 2020 Assets Impaired loans: Reverse mortgage $ — $ — $ 311 $ 311 Other real estate owned — — 51 51 $ — $ — $ 362 $ 362 Fair Value Measurements Using Quoted Prices Significant Other Significant Level 1 Level 2 Level 3 Total (Dollars in thousands) December 31, 2019 Assets Impaired loans: Real estate: One-to-four family $ — $ — $ 56 $ 56 Reverse mortgage — — 308 308 Other real estate owned — — 128 128 $ — $ — $ 492 $ 492 Quantitative Information about Level 3 Fair Value Measurements The following table presents the valuation methodology and unobservable inputs for Level 3 assets measured at fair value on a nonrecurring basis as of the date indicated: Fair Value Valuation Technique(s) Significant Range Weighted Average (1) (Dollars in thousands) June 30, 2020 Collateral-dependent impaired loans $ 311 Market comparable properties Marketability discount 10.0 % 10.0 % Selling cost 8.0 % 8.0 % Other real estate owned 51 Market comparable properties Sales commission 6.0 % 6.0 % Other selling costs 2.0 % 2.0 % ________________________ (1) Unobservable inputs were weighted by the relative fair value of the instruments. Financial Instruments Not Required To Be Carried At Fair Value FASB ASC Topic 825, Financial Instruments , requires the disclosure of the estimated fair value of financial instruments. The Company’s estimated fair value amounts have been determined by the Company using available market information and appropriate valuation methodologies. However, considerable judgment is required to develop the estimates of fair value. Accordingly, the estimates are not necessarily indicative of the amounts the Company could have realized in a current market exchange. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. The following tables present information about the Company’s assets and liabilities that are not measured at fair value in the consolidated statements of financial condition as of the dates presented: Carrying Fair Value Measurements Using Level 1 Level 2 Level 3 Total (Dollars in thousands) June 30, 2020 Financial assets: Cash and due from banks $ 13,777 $ 13,777 $ — $ — $ 13,777 Interest earning deposits 185,667 185,667 — — 185,667 Loans held-for-sale 321,835 — 321,835 — 321,835 Loans held-for-investment, net 793,548 — — 795,748 795,748 Accrued interest receivable 7,700 3 2,063 5,634 7,700 Financial liabilities: Deposits $ 1,670,909 $ — $ 1,769,100 $ — $ 1,769,100 FHLB advances 360,000 — 360,000 — 360,000 Subordinated debentures 15,823 — 15,038 — 15,038 Accrued interest payable 322 — 322 — 322 Carrying Fair Value Measurements Using Level 1 Level 2 Level 3 Total (Dollars in thousands) December 31, 2019 Financial assets: Cash and due from banks $ 1,579 $ 1,579 $ — $ — $ 1,579 Interest earning deposits 132,025 132,025 — — 132,025 Loans held-for-sale 375,922 — 376,126 — 376,126 Loans held-for-investment, net 664,622 — — 666,272 666,272 Accrued interest receivable 5,950 86 3,643 2,221 5,950 Financial liabilities: Deposits $ 1,814,654 $ — $ 1,826,100 $ — $ 1,826,100 Notes payable 3,714 — 3,714 — 3,714 Subordinated debentures 15,816 — 15,203 — 15,203 Accrued interest payable 559 — 559 — 559

Accounting Policies [Abstract]
Nature of Business	Nature of Business The accompanying consolidated financial statements include the accounts of Silvergate Capital Corporation, a Maryland corporation and its wholly-owned subsidiary, Silvergate Bank (the “Bank”), collectively referred to as (the “Company” or “Silvergate”). The Bank was incorporated in 1987 and commenced business in 1988 under the California Financial Code as an industrial bank. In February 2009 the Bank converted its charter to a California commercial bank, which gave it the added authority to accept demand deposits. At the same time, the Company also became a registered bank holding company under the federal Bank Holding Company Act. The Bank became a member of the Federal Reserve System in December 2012. The Bank is subject to regulation by the California Department of Business Oversight (“DBO”), and the Federal Reserve Bank of San Francisco (“FRB”), and its deposits are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to applicable legal limits.
Financial Statement Preparation and Presentation	Financial Statement Preparation and Presentation The accompanying interim condensed consolidated financial statements have been prepared by the Company, without audit, in accordance with the instructions to the Quarterly Report on Form 10-Q, and Rule 10-01 of Regulation S-X promulgated by the United States Securities and Exchange Commission (the “SEC”) and, therefore, do not include all information and footnotes necessary for a fair presentation of its consolidated financial statements in accordance with accounting principles generally accepted in the United States (“GAAP”). In the opinion of management, the unaudited financial information for the interim periods presented reflects all adjustments, consisting of only normal and recurring adjustments, necessary for a fair statement of the Company’s condensed consolidated financial statements. These consolidated statements should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2019, included in the Company’s Annual Report on Form 10-K dated March 10, 2020. Operating results for interim periods are not necessarily indicative of operating results for an entire fiscal year. The consolidated financial statements include the accounts of the Company and all other entities in which it has a controlling financial interest. All significant intercompany accounts and transactions have been eliminated in consolidation. Unless the context requires otherwise, all references to the Company include its wholly owned subsidiaries. The accounting and reporting policies of the Company are based upon GAAP and conform to predominant practices within the financial services industry. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts and the disclosure of contingent amounts in the Company’s financial statements and the accompanying notes. We evaluate estimates on an ongoing basis including the economic impact of Coronavirus Disease 2019 (or “COVID-19”). Actual results could materially differ from those estimates.
Recently issued accounting pronouncements not yet effective	Recently issued accounting pronouncements not yet effective In June 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (or “ASU”) 2016-13, Financial Instruments-Credit Losses (Topic 326) to replace the incurred loss model with an expected loss model, which is referred to as the current expected credit loss (or “CECL”) model. The CECL model is applicable to the measurement of credit losses on financial assets measured at amortized cost, including loan receivables, held to maturity debt securities, and reinsurance receivables. It also applies to off-balance sheet credit exposures not accounted for as insurance (loan commitments, standby letters of credit, financial guarantees, and other similar instruments) and net investments in leases recognized by a lessor. These amendments were initially effective for fiscal years beginning after December 15, 2019 for SEC registrants and after December 15, 2020, for Public Business Entities, or PBEs. In November 2019, the FASB issued ASU 2019-10, Financial Instruments-Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates, which finalized the delay of the effective date for smaller reporting companies, such as the Company, to apply the standards related to CECL, until fiscal years beginning after December 15, 2022. For debt securities with other than temporary impairment (OTTI), the guidance will be applied prospectively and for existing purchased credit impaired (PCI) assets will be grandfathered and classified as purchased credit deteriorated (PCD) assets at the date of adoption. The asset will be grossed up for the allowance for expected credit losses for all PCD assets at the date of adoption and will continue to recognize the noncredit discount in interest income based on the yield such assets as of the adoption date. Subsequent changes in expected credit losses will be recorded through the allowance. For all other assets with the scope of CECL, the cumulative effect adjustment will be recognized in retained earnings as of the beginning of the first reporting period in which the guidance is effective. In November 2018, the FASB issued ASU 2018-19, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, which clarify that receivables arising from operating leases are not within the scope of Subtopic 326-20. Instead, impairment of receivables arising from operating leases should be accounted for in accordance with Topic 842, Leases. The Company formed a CECL implementation committee in 2018 which prepared a project plan to migrate towards the adoption date. As part of the project plan, the Company contracted a third-party vendor to assist in the application and analysis of ASU 2016-13 as well as a third-party vendor to perform an independent model validation. As part of this process, the Company has determined preliminary loan pool segmentation under CECL, as well as evaluated the key economic loss drivers for each segment. The Company operationalized an initial CECL model during the second quarter of 2019 and is running this preliminary CECL model alongside the existing incurred loss methodology. The Company intends to continue to refine and run the model until the date of adoption. The Company continues to evaluate the effects of ASU 2016-13 on its financial statements and disclosures and whether to early adopt the guidance. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (or “ASU 2020-04”), which provides temporary, optional guidance to ease the potential burden in accounting for, or recognizing the effects of, the transition away from the London Interbank Offered Rate (or “LIBOR”) or other interbank offered rate (reference rates) on financial reporting, which currently is expected to be discontinued by the end of 2021. To help with the transition to new reference rates, the ASU provides optional expedients and exceptions for applying GAAP to affected contract modifications and hedge accounting relationships. The guidance is applicable only to contracts or hedge accounting relationships that reference LIBOR or another reference rate expected to be discontinued. The expedients and exceptions in this update are available to all entities starting March 12, 2020 through December 31, 2022. The Company is evaluating the impact that ASU 2020-04 will have on those financial assets where LIBOR is used as an index rate.

Financing Receivable Credit Quality Indicators Description	The Company uses the following definitions for risk ratings: Pass : Loans in all classes that are not adversely rated, are contractually current as to principal and interest, and are otherwise in compliance with the contractual terms of the loan agreement. Management believes that there is a low likelihood of loss related to those loans that are considered pass. Special mention : Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date. Substandard : Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Doubtful : Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Loss : Credits rated as loss are charged-off. Management has no expectation of the recovery of any payments in respect of credits rated as loss.
