Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations	1. NATURE OF OPERATIONS Organization California BanCorp (the “Company”, or ‘we”), a California corporation headquartered in Oakland, California, is the bank holding company for its wholly-owned subsidiary California Bank of Commerce (the “Bank”). The Bank has 2 full service branches in California located in Contra Costa County and Santa Clara County and 4 loan production offices in California located in Alameda County, Contra Costa County, Sacramento County, and Santa Clara County. Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q 10-K The results of operations for the three and nine months ended September 30, 2020 are not necessarily indicative of the results of operations that may be expected for any other interim period or for the year ending December 31, 2020. The Company’s accounting and reporting policies conform to GAAP and to general practices within the banking industry. Subsequent Events Management has reviewed all events through the date the unaudited consolidated financial statements were filed with the SEC. See Note 7 to the unaudited consolidated financial statements for additional information regarding the COVID-19 pandemic. Use of Estimates Management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates and assumptions affect the amounts reported in the unaudited consolidated financial statements and the disclosures provided, and actual results could differ. The estimates utilized to determine the appropriate allowance for loan losses at September 30, 2020 may be materially different from actual results due to the COVID-19 pandemic. See Note 7 to the unaudited consolidated financial statements for additional information regarding the COVID-19 pandemic. Reclassifications Certain prior balances in the unaudited consolidated financial statements may have been reclassified to conform to current year presentation. These reclassifications had no effect on prior year net income or shareholders’ equity. Specifically, we have modified how we disclose our loan segments to be purpose-based versus collateral-based (as previously disclosed) so that there is more transparency to our SBA loan portfolio which now consists largely of Paycheck Protection Program loans under the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”). As a result, prior balances for both the current and prior year in the unaudited consolidated statements have been reclassified. These reclassifications had no effect on current or prior year net income, shareholders’ equity, total gross loan balances, or the overall balance of the allowance for credit losses. Earnings Per Share (“EPS”) Basic earnings per common share represents the amount of earnings for the period available to each share of common stock outstanding during the reporting period. Basic EPS is computed based upon net income divided by the weighted average number of common shares outstanding during the period. In determining the weighted average number of shares outstanding, vested restricted stock units are included. Diluted EPS represents the amount of earnings for the period available to each share of common stock outstanding including common stock that would have been outstanding assuming the issuance of common shares for all dilutive potential common shares outstanding during each reporting period. Diluted EPS is computed based upon net income divided by the weighted average number of common shares outstanding during each period, adjusted for the effect of dilutive potential common shares, such as restricted stock awards and units, calculated using the treasury stock method.

The Company purchased 8 securities for $35.4 million and sold 6 available for sale securities for total proceeds of $7.7 million during the nine months ended September 30, 2020. The Company did not purchase or sell available for sale investment securities during the nine months ended September 30, 2019. The following table summarizes securities with unrealized losses at September 30, 2020 and December 31, 2019 aggregated by major security type and length of time in a continuous unrealized loss position.

Management believes that changes in the market value since purchase are primarily attributable to changes in interest rates and relative illiquidity. Because the Company does not intend to sell and is unlikely to be required to sell until a recovery of fair value, which may be at maturity, the Company did not consider those investments to be other-than-temporarily impaired at September 30, 2020. At December 31, 2019, the Company’s investment security portfolio consisted of 21 securities, two of which were in an unrealized loss position at year end. One security was a government agency security issued by the Small Business Administration. One security was a Mortgage-Backed-Security. Management believes that changes in the market value of its Mortgage-Backed-Securities since purchase are primarily attributable to changes in interest rates and relative illiquidity and not credit quality. Because the Company does not intend to sell and unlikely to be required to sell until a recovery of fair value, which may be at maturity, the Company did not consider those investments to be other-than-temporarily impaired at December 31, 2019. The following table summarizes the scheduled maturities of available for sale investment securities as of September 30, 2020. September 30, 2020 Amortized Fair (Dollars in thousands) Cost Value Available for sale securities: Less that one year $ — $ — One to five years — — Five to ten years — — Beyond ten years 15,535 15,818 Securities not due at a single maturity date 34,259 35,088 Total available for sale securities $ 49,794 $ 50,906 The amortized cost and fair value of debt securities are shown by contractual maturity. Expected maturities may differ from contractual maturities if borrowers have the right to call or prepay obligations with or without call or prepayment penalties. As such, mortgage backed securities and government agencies are not included in the maturity categories above and instead are shown separately as securities not due at a single maturity date.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	6. FAIR VALUE MEASUREMENTS Fair Value Hierarchy The Company groups its assets and liabilities measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. Valuations within these levels are based upon: Level 1—Quoted market prices for identical instruments traded in active exchange markets. Level 2—Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable or can be corroborated by observable market data. Level 3—Model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect the Company’s estimates of assumptions that market participants would use on pricing the asset or liability. Valuation techniques include management judgment and estimation which may be significant. Management monitors the availability of observable market data to assess the appropriate classification of financial instruments within the fair value hierarchy. Changes in economic conditions or model-based valuation techniques may require the transfer of financial instruments from one fair value level to another. In such instances, the transfer is reported at the beginning of the reporting period. Management evaluates the significance of transfers between levels based upon the nature of the financial instrument and size of the transfer relative to total assets, total liabilities or total earnings. The carrying amounts and estimated fair values of financial instruments at September 30, 2020 and December 31, 2019 are as follows: Carrying Fair Value Measurements (Dollars in thousands) Amount Level 1 Level 2 Level 3 Total As of September 30, 2020 Financial assets: Cash and due from banks $ 503,894 $ 503,894 $ — $ — $ 503,894 Securities available for sale 50,906 — 50,906 — 50,906 Loans, net 1,340,725 — — 1,343,541 1,343,541 Accrued interest receivable 6,488 — 103 6,385 6,488 Financial liabilities: Deposits $ 1,437,232 $ 1,301,370 $ 135,875 $ — $ 1,437,245 Other borrowings 352,703 — — 352,824 352,824 Subordinated debt 24,990 — — 24,633 24,633 Accrued interest payable 640 — 51 589 640 As of December 31, 2019 Financial assets: Cash and due from banks $ 114,342 $ 114,342 $ — $ — $ 114,342 Securities available for sale 28,555 — 28,555 — 28,555 Loans, net 941,132 — — 940,944 940,944 Accrued interest receivable 3,398 — 168 3,230 3,398 Financial liabilities: Deposits $ 988,236 $ 870,495 $ 121,136 $ — $ 991,631 Other borrowings 10,000 — — 10,032 10,032 Subordinated debt 4,977 — — 5,112 5,112 Accrued interest payable 400 — 326 74 400 These estimates do not reflect any premium or discount that could result from offering the Company’s entire holdings of a particular financial instrument for sale at one time, nor do they attempt to estimate the value of anticipated future business related to the instruments. In addition, the tax ramifications related to the realization of unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in any of these estimates. The methods and assumptions used to estimate fair values are described as follows: Cash and Due from banks—The carrying amounts of cash and short-term instruments approximate fair values and are classified as Level 1. Investment Securities—Since quoted prices are generally not available for identical securities, fair values are calculated based on market prices of similar securities on similar dates, resulting in Level 2 classification. FHLB, IBFC, PCBB Stock—It is not practical to determine the fair value of these correspondent bank stocks due to restrictions placed on their transferability. Loans—Fair values of loans for September 30, 2020 and December 31, 2019 are estimated on an exit price basis with contractual cash flow, prepayments, discount spreads, credit loss and liquidity premium assumptions. Loans with similar characteristics such as prepayment rates, terms and rate indexed are aggregated for purposes of the calculations. Impaired loans—Impaired loans are evaluated on a quarterly basis for additional impairment and adjusted accordingly. The fair value of impaired loans with specific allocations of the allowance for loan losses that are secured by real property is generally based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. The methods utilized to estimate the fair value of impaired loans do not necessarily represent an exit price. Deposits—The fair values disclosed for demand deposits (e.g., interest and non-interest FHLB Advances—FHLB Advances are included in Other Borrowings. Fair values for FHLB Advances are estimated using discounted cash flow analyses using interest rates offered at each reporting date by correspondent banks for advances with similar maturities resulting in Level 3 classification. Paycheck Protection Program Liquidity Facility (PPPLF)—The fair value of PPPLF is estimated using a discounted cash flow based on the remaining contractual term and current rates at which similar advances would be obtained resulting in Level 3 classification. Senior Notes—Fair values for senior notes are estimated using a discounted cash flow calculation based on current rates for similar types of debt which may be unobservable, and considering recent trading activity of similar instruments in market which can be inactive and accordingly are classified within in the Level 3 classification. Subordinated Debt—Fair values for subordinated debt are calculated based on its terms and were discounted to the date of the valuation to calculate the fair value on the debt. A market rate based on recent debt offering by peer bank was used to discount cash flow until reprice date and subsequently cash flow were discounted at Prime plus 2% for its security. These assumptions which may be unobservable, and considering recent trading activity of similar instruments in market which can be inactive and accordingly are classified within the Level 3 classification. Accrued Interest Receivable—The carrying amounts of accrued interest receivable approximate fair value resulting in a Level 2 classification for accrued interest receivable on investment securities and a Level 3 classification for accrued interest receivable on loans since investment securities are generally classified using Level 2 inputs and loans are generally classified using Level 3 inputs. Accrued Interest Payable—The carrying amounts of accrued interest payable approximate fair value resulting in a Level 2 classification, since accrued interest payable is from deposits that are generally classified using Level 2 inputs. Off Balance Sheet Instruments—Fair values for off-balance Assets Recorded at Fair Value on a Recurring Basis The Company is required or permitted to record the following assets at fair value on a recurring basis. (Dollars in thousands) Fair Value Level 1 Level 2 Level 3 As of September 30, 2020 Investments available for sale: Mortgage backed securities $ 32,649 $ — $ 32,649 $ — Government agencies 2,439 — 2,439 — Corporate bonds 15,818 — 15,818 — Total assets measured at fair value on a recurring basis $ 50,906 $ — $ 50,906 $ — As of December 31, 2019 Investments available for sale: Mortgage backed securities $ 20,722 $ — $ 20,722 $ — Government agencies 7,833 — 7,833 — Corporate bonds — — — — Total assets measured at fair value on a recurring basis $ 28,555 $ — $ 28,555 $ — Fair values for available-for-sale Assets Recorded at Fair Value on a Non-Recurring The Company may be required, from time to time, to measure certain assets at fair value on a non-recurring non-recurring Carrying Fair Value Measurements (Dollars in thousands) Amount Level 1 Level 2 Level 3 As of September 31, 2020 Impaired loans - Commercial $ 346 $ — $ — $ 346 Impaired loans - SBA $ 234 $ — $ — $ 234 Total assets measured at fair value on a non-recurring $ 580 $ — $ — $ 580 As of December 31, 2019 Impaired loans - Commercial $ 2,474 $ — $ — $ 2,474 Impaired loans - Real estate other 705 705 Impaired loans - SBA 296 296 Total assets measured at fair value on a non-recurring $ 3,475 $ — $ — $ 3,475 The fair value of impaired loans is based upon independent market prices, estimated liquidation values of loan collateral or appraised value of the collateral as determined by third-party independent appraisers, less selling costs, generally.

Business Impact Of Covid-19

Text Block [Abstract]
Business Impact Of Covid-19	7. BUSINESS IMPACT OF COVID-19 In December 2019, a novel strain of coronavirus, COVID-19, was reported in Wuhan, China. The COVID-19 virus continues to aggressively spread globally and has spread to over 185 countries, including all 50 states in the United States. A prolonged COVID-19 outbreak, or any other epidemic that harms the global economy, U.S. economy, or the economies in which we operate could adversely affect our operations. While the spread of the COVID-19 virus has minimally impacted our operations as of September 30, 2020, it has caused significant economic disruption throughout the United States as state and local governments issued “shelter at home” orders along with the closing of non-essential Investments Management has analyzed the investment portfolio and determined that any impairment would be temporary based on the type of investments the company holds. As part of the Company’s assessment of other-than-temporary-impairment (OTTI), management considered coronavirus COVID-19 and determined that the significant change in the general economic environment and financial markets represents an interim impairment indicator that will require continued evaluation. As a result, there is a reasonable possibility that OTTI could occur in the near term. Loan Portfolio The Company has taken measures to both support customers affected by the pandemic and to maintain strong asset quality, including implementing a broad-based risk management strategy to manage credit segments on a real-time basis, and monitoring portfolio risk and related mitigation strategies also by segment. The CARES Act and the revised interagency guidance issued in April 2020, “Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working With Customers Affected by the Coronavirus (Revised)”, provide banks the option to temporarily suspend certain requirements under GAAP related to Troubled Debt Restructurings (“TDRs”) for a limited time to account for the effects of COVID-19. As a result, the Company will not be recognizing eligible COVID-19 loan modifications as TDRs. Additionally, 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. However, management continues to evaluate these loans for performance criteria separate from their respective COVID-19 loan modification status. Through the date of this filing, the Company has not experienced any loan charge-offs caused by the economic impact from COVID-19. Management has evaluated events related to COVID-19 that have occurred subsequent to September 30, 2020 and has concluded there are no matters that would require recognition in the accompanying unaudited consolidated financial statements. Proactive Deferral Program: As a result of the novel coronavirus COVID-19, through September 30, 2020 the Company granted payment deferments on approximately 385 loans with an aggregate outstanding balance of approximately $323.9 million and aggregate monthly principal and interest payments of approximately $3.7 million, none of which are considered to be TDRs, based on the relief provided under the CARES Act described above. The payment deferments were granted initially for up to 90 days, and the Company has considered an additional 90 days based on the circumstances on both a macro and micro level at the time. Of the initial deferments, 6 borrowers with 8 loans totaling $12.5 million have applied for an additional 90 day extension. As of the date of this filing, with the exception of these 8 loans, all loans that encompassed the original deferment pool have returned to a normal payment schedule. Paycheck Protection Program (PPP): The Company is also participating in the SBA Paycheck Protection Program (PPP). Key Features of the PPP include: • 24-month • Interest-rate of 1%, deferred payments for the first 6-months • The loan will be fully forgiven if the funds are used for payroll costs, interest on mortgages, rent, and utilities (due to likely high subscription, at least 75% of the forgiven amount must have been used for payroll). No collateral or personal guarantees are required. Neither the government nor lenders will charge any fees. • Forgiveness is based on the employer maintaining or quickly rehiring employees and maintaining salary levels. Forgiveness will be reduced if full-time headcount declines, or if salaries and wages decrease. • Loans are guaranteed by the United States Treasury Department The Company processed 100% of the approximately 737 applications received and all of the eligible applications that were submitted to the SBA received approval. At September 30, 2020, the balance of the loans funded under the PPP was $362.0 million. The following table reflects the concentration of loans funded through the Paycheck Protection Program Liquidity Facility (PPPLF) as of September 30, 2020. Number of Principal Number of Loans as a % of Principal Balance as a % of (Dollars in millions) Loans Balance PPP Loans Gross Loans PPP Loans Gross Loans Dental services 284 $ 42.8 39 % 14 % 12 % 3 % Contractors 114 138.0 16 % 6 % 38 % 10 % Other 333 181.2 46 % 15 % 50 % 13 % Total 731 $ 362.0 100 % 35 % 100 % 26 % The PPP loans categorized above as “other” are comprised of multiple sectors, including professional/scientific services, retail, manufacturing, finance, wholesale, and real estate. The SBA began accepting client applications for loan forgiveness in August 2020. The Company has submitted 43 client applications to the SBA totaling $32.2 million. As of the date of this filing, clients representing an additional 174 loans totaling $120.7 million are in the process of completing loan forgiveness applications. Impact of Response to COVID-19 Pandemic Specific impacts of the COVID-19 macroeconomic environment on our operating results for the third quarter and first nine months of 2020 include the following: • Funding of loans under the PPP and related borrowing under the Paycheck Protection Program Liquidity Facility (PPPLF) provided net benefit to net interest income of $1.4 million and $2.8 million during the third quarter and nine months ended September 30, 2020, respectively, including the impact of amortization of deferred fees and origination costs. • The Company received $9.1 million in fees year-to-date related to the origination of PPP loans. Recognition of the fees was deferred at origination and is being recognized over the 24 month term of the loans. For the third quarter and nine months ended September 30, 2020, the Company amortized into interest income approximately $1.1 million and $2.3 million, respectively. As clients are accepted for loan forgiveness by the SBA, the remaining fees will be recognized at the time of payoff of the loan. • The Company deferred loan origination costs of approximately $2.5 million year-to-date year-to-date • The continued uncertainty regarding the severity and duration of the pandemic and related economic effects considered in our qualitative assessment of the allowance for loan losses resulted in a gross increase in the provision for the third quarter and nine months ended September 30, 2020 of approximately million, respectively. Our overall analysis of the allowance for loan losses considers multiple qualitative factors that may, in part, offset the gross impact on the provision specifically related to COVID-19. Goodwill The Company completed an impairment analysis of goodwill as of September 30, 2020 and determined there was no impairment. Goodwill impairment exists when a reporting unit’s carrying value exceeds its fair value, which is determined through a qualitative assessment whether it is more likely than not that the fair value of equity of the reporting unit exceeds the carrying value (“Step Zero”). As part of the Company’s qualitative assessment of goodwill impairment, management considered the triggering event of coronavirus COVID-19 and determined that the significant change in the general economic environment and financial markets, including our market capitalization, represents an interim impairment indicator that will require continued evaluation. However, we do not believe that it is more likely than not that a goodwill impairment exists as of September 30, 2020.
