Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations	1. NATURE OF OPERATIONS Organization California BanCorp (the “Company”), a California corporation headquartered in Oakland, California, is the bank holding company for its wholly-owned subsidiary California Bank of Commerce (the “Bank”), which offers a broad range of commercial banking services to closely held businesses and professionals located throughout Northern California. The Bank has a full-service branch located in Contra Costa County and 4 loan production offices 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, 2023 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, 2023. The Company’s accounting and reporting policies conform to GAAP and to general practices within the banking industry. Use of Estimates The preparation of financial statements in conformity with GAAP requires management 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 consolidated financial statements, and the reported amounts of revenues and expenses during the reporting periods presented. Actual results may differ from those estimates used in the Consolidated Financial Statements and related notes. Material estimates that are particularly susceptible to significant changes in the near term include estimates relating to: the determination of the allowance for credit losses; certain assets and liabilities carried at fair value; and accounting for income taxes. 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. Subsequent Events Management has reviewed all events through the date the unaudited consolidated financial statements were filed with the SEC and concluded that no event required any adjustment to the balances presented. Goodwill 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”). The Company completed an interim impairment analysis of goodwill as of September 30, 2023 and determined there was no impairment. 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 ACL on loans is a valuation account that is deducted from the amortized cost basis of loans to present the net amount expected to be collected. Amortized cost does not include accrued interest, which management elected to exclude for the estimate of expected credit losses. The ACL on loans is increased by the provision for credit losses on loans, which is charged against current period operating results, and decreased by reversals of credit loss provisions as well as loan charge-offs, net of recoveries. Management’s determination of the ACL on loans is based on an evaluation of the composition of the loan portfolio, current economic conditions, historical loan loss experience, reasonable and supportable forecasts, and other risk factors. Loans with similar risk characteristics are collectively assessed within pools (or segments). The discounted cash flow (“DCF”) method is the primary credit loss estimation methodology used by the Company and involves estimating future cash flows for each individual loan and discounting them back to their present value using the loan’s contractual interest rate, which is adjusted for any net deferred fees, costs, premiums, or discounts existing at the loan’s origination or acquisition date (also referred to as the effective interest rate). The DCF method also considers factors such as loan term, prepayment or curtailment assumptions, and other relevant economic factors that could affect future cash flows. By discounting the cash flows, the method incorporates the time value of money and reflects the credit risk inherent in the loan. The Company utilizes a forecast period of one year and then reverts to the mean of historical loss rates on a straight-line basis over the following one-year Additionally, management considers qualitative and environmental factors that are likely to cause estimated credit losses within the Company’s existing portfolio to differ from historical loss (or peer) experience. Qualitative and environmental factors may include: consideration in trends of delinquencies, nonaccrual loans, and charged-off • Allowance for Credit Losses on Off-Balance The Company maintains an ACL on unfunded loan commitments and other off-balance off-balance • Allowance for Credit Losses on Available for Sale Securities For available for sale securities in an unrealized loss position, the Company initially assesses whether it intends to sell, or it is more likely than not that it will be required to sell, the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost is written down to fair value through income. For available for sale securities that do not meet this criteria, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. If a credit loss exists an allowance for credit losses is recorded, through a charge to the provision to credit losses, to the extent that the fair value is less than the amortized cost basis. Accrued interest receivable on available for sale securities is excluded from the estimate of credit losses. The Company did not have any available for sale securities that required an ACL at September 30, 2023. • Allowance for Credit Losses on Held to Maturity Securities The Company measures expected credit losses on held to maturity investment securities on a collective basis by major security type. Accrued interest receivable on held to maturity investment securities is excluded from the estimate of credit losses. The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. Changes in the ACL for held to maturity securities are recorded through the provision for credit losses in the consolidated statements of income.

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, certain securities are not included in the specific maturity categories above and instead are shown separately as securities not due at a single maturity date. Management monitors the credit quality of the investment portfolio through the use of credit ratings by major credit agencies and analysis of issuer financial information, if available. Additionally, securities issued by government-sponsored agencies, such as FNMA, FHLMC and SBA, have explicit credit guarantees by the United States Federal Government which protect us from credit losses on the contractual cash flows of the securities.

No allowances for credit losses have been recognized, individually or collectively, on available for sale securities in an unrealized loss position, as management does not believe any of the securities are impaired due to reasons of credit quality at September 30, 2023. The Company measures expected credit losses on held to maturity securities collectively by major security type sharing similar risk characteristics, and considers historical credit loss information that is adjusted for current conditions along with reasonable and supportable forecasts. As of September 30, 2023, the Company determined that an allowance for credit losses of $81,000 was required for held to maturity securities. The allowance for credit losses pertained to corporate bonds and was presented as a reduction to the amortized cost of held to maturity securities outstanding. The following table presents the balance and activity in the allowance for credit losses on held to maturity securities for the three and nine months ended September 30, 2023. September 30, 2023 Three Nine (Dollars in thousands) Months Ended Months Ended Beginning balance $ 58 $ — Adoption of new accounting standard — 110 Provision for credit losses 23 (29 ) Net charge-offs — — Balance at September 30, 2023 $ 81 $ 81 On a quarterly basis, the Company utilizes a comprehensive risk assessment which includes an external rating methodology to identify, measure, and monitor risks associated with our held to maturity loan portfolio. The provision for credit losses in the third quarter of 2023 was primarily driven by an increase in the risk of default pertaining to certain securities in the held to maturity portfolio, and was identified as part of the comprehensive quarterly analysis.

Loans and Allowance For Credit Losses	3. LOANS AND ALLOWANCE FOR CREDIT LOSSES Outstanding loans as of September 30, 2023 and December 31, 2022 are summarized below. Certain loans have been pledged to secure borrowing arrangements (see Note 4). September 30, December 31, (Dollars in thousands) 2023 2022 Commercial and industrial $ 633,902 $ 634,535 Real estate - other 858,611 848,241 Real estate - construction and land 40,003 63,730 SBA 4,415 7,220 Other 36,184 39,695 Total loans, gross 1,573,115 1,593,421 Deferred loan origination costs, net 1,312 2,040 Allowance for credit losses (15,921 ) (17,005 ) Total loans, net $ 1,558,506 $ 1,578,456 The Company categorizes its loan portfolio into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans individually to classify the loans as to credit risk. The Company uses the following definitions for risk ratings: Special Mention: A Special Mention credit has potential weaknesses that require management’s close attention. If left uncorrected, these potential weaknesses may result in the deterioration of the repayment prospects for the asset or in the Company’s credit position at some future date. Special Mention assets are not adversely classified and do not expose the Company to sufficient risk to warrant adverse classification. Substandard: Substandard credits are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified must have a well-defined weakness or weaknesses that jeopardize 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: A Doubtful credit has all the weaknesses inherent in Substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently known facts, conditions and values, highly questionable and improbable. Loans not meeting the criteria above that are analyzed individually, as part of the above described process, are considered to be pass-rated loans. The following table reflects the Company’s recorded investment in loans by credit quality indicators and by year of origination as of September 30, 2023.

Loans that do not share risk characteristics are evaluated on an individual basis. When management determines that foreclosure is probable and the borrower is experiencing financial difficulty, the expected credit losses are based on the fair value of collateral at the reporting dated and adjusted for selling costs as appropriate. At September 30, 2023 and December 31, 2022, the Company determined that certain loans did not share risk characteristics with other loans in the portfolio and therefore evaluated these loans for expected credit losses/impairment on an individual basis. The loans individually evaluated were classified as nonaccrual and were all collateral dependent. For collateral dependent loans, the Company has adopted the practical expedient under ASC 326 to measure the allowance for credit losses based on the fair value of collateral. The allowance for credit losses is calculated on an individual loan basis based on the shortfall between the fair value of the loan’s collateral, which is adjusted for liquidation costs/discounts, and amortized cost. If the fair value of the collateral exceeds the amortized cost, no allowance is required. None of the individually evaluated loans required an allowance for credit losses as of the respective reporting dates. The following table reflects the recorded investment and unpaid principal balance for loans individually evaluated for expected credit losses/impairment as of September 30, 2023 and December 31, 2022 under ASC 326 and the previous accounting standard, respectively.

The starting point for the estimate of the allowance for credit losses is historical loss information, which includes losses from modifications of receivables to borrowers experiencing financial difficulty. The Company uses a probability of default/loss given default model to determine the allowance for credit losses. An assessment of whether a borrower is experiencing financial difficulty is made on the date of a modification. The effect of most modifications made to borrowers experiencing financial difficulty is already included in the allowance for credit losses because of the measurement methodologies used to estimate the allowance, therefore a change to the allowance for credit losses is generally not recorded upon modification. In some cases, the Company will modify a certain loan by providing multiple types of concessions. Typically, one type of concession, such as a term extension, is granted initially. If the borrower continues to experience financial difficulty, another concession, such as an interest rate reduction or principal forgiveness, may be granted. Upon the Company’s determination that a modified loan (or a portion of a loan) has subsequently been deemed uncollectible, the loan (or a portion of that loan) is written off. Therefore, the amortized cost basis of the loan is reduced by the uncollectible amount and the allowance for credit losses is adjusted by the same amount. At September 30, 2023, the Company had one loan with a recorded investment or commitment with terms that had been modified due to the borrower experiencing financial difficulties. This loan had no payments that were considered past due as of the reporting date. The following table reflects the type of concession granted and the financial effect of the modification. (Dollars in thousands) Amortized % of Total Financial Effect SBA $ 50 1.13 % Term Extension - extended forbearance expiration from March 31, 2023 to April 1, 2024 Total modified loans $ 50 The Company had no loan modifications resulting from a borrower experiencing financial difficulties with a subsequent payment default within twelve months following the modification during the three and nine months ended September 30, 2023.

Commitments and Contingent Liabilities	5. COMMITMENTS AND CONTINGENT LIABILITIES Financial Instruments with Off-Balance The Company is a party to financial instruments with off-balance 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. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since some of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case At September 30, 2023 and December 31, 2022, the Company had outstanding unfunded commitments for loans of approximately $643.4 million and $644.1 million, respectively. The outstanding unfunded commitments for loans at September 30, 2023 was comprised of fixed rate commitments of approximately $43.0 million and variable rate commitments of approximately $600.4 million. The following table reflects the interest rate and maturity ranges for the unfunded fixed rate loan commitments as of September 30, 2023.

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, 2023 and December 31, 2022 are as follows: Carrying Fair Value Measurements (Dollars in thousands) Amount Level 1 Level 2 Level 3 Total As of September 30, 2023: Financial assets: Cash and cash equivalents $ 198,982 $ 198,982 $ — $ — $ 198,982 Investment securities: Available for sale 44,227 — 44,227 — 44,227 Held to maturity 105,017 83,675 7,197 90,872 Loans, net 1,558,506 — — 1,478,998 1,478,998 Accrued interest receivable 9,020 — 1,096 7,924 9,020 Financial liabilities: Deposits $ 1,707,081 $ 1,387,376 $ 320,344 $ — $ 1,707,720 Subordinated debt 54,256 — — 49,803 49,803 Accrued interest payable 4,024 — 3,922 102 4,024 As of December 31, 2022: Financial assets: Cash and due from banks $ 232,382 $ 232,382 $ — $ — $ 232,382 Investment securities: Available for sale 47,012 — 47,012 — 47,012 Held to maturity 108,866 89,433 7,450 96,883 Loans, net 1,578,456 — 1,519,903 1,519,903 Accrued interest receivable 7,769 — 926 6,843 7,769 Financial liabilities: Deposits $ 1,791,740 $ 1,520,502 $ 271,178 $ — $ 1,791,680 Subordinated debt 54,152 — — 49,027 49,027 Accrued interest payable 1,678 — 1,007 671 1,678 These e s 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. For securities where market prices of similar securities are not available, fair values are calculated using discounted cash flows or other market indicators, resulting in Level 3 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, 2023 and December 31, 2022 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. Loans are generally classified using Level 3 inputs. Loans individually evaluated for expected credit losses/impairment—Certain loans are individually evaluated on a quarterly basis for additional expected credit losses/impairment and adjusted accordingly. The fair value of loans that are individually evaluated with specific allocations of the allowance for credit 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 individually evaluated 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. 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 by considering recent trading activity of similar instruments in the market, which may be inactive. Accordingly, senior notes are classified within the Level 3 classification. Junior Subordinated Debt Securities - Fair values for subordinated debt are calculated based on their respective terms and discounted to the date of the valuation. A market rate based on recent debt offerings by peer banks, which may be unobservable, is used to discount the cash flows until the repricing date and the subsequent cash flows are discounted at Prime plus 2%. Additionally, the Company considers recent trading activity of similar instruments in the market, which may be inactive. Accordingly, junior subordinated debt securities 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 as of September 30, 2023 and December 31, 2022. (Dollars in thousands) Fair Value Level 1 Level 2 Level 3 As of September 30, 2023: Investments available for sale: Mortgage backed securities $ 15,175 $ — $ 15,175 $ — Government agencies 29,052 — 29,052 — Total assets measured at fair value on a recurring basis $ 44,227 $ — $ 44,227 $ — As of December 31, 2022: Investments available for sale: Mortgage backed securities $ 17,758 $ — $ 17,758 $ — Government agencies 28,766 — 28,766 — Corporate bonds 488 — 488 — Total assets measured at fair value on a recurring basis $ 47,012 $ — $ 47,012 $ — Fair values for available-for-sale no 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 30, 2023: Individually evaluated loans - Commercial $ 1,183 $ — $ — $ 1,183 Individually evaluated loans - SBA 53 — — 53 Total assets measured at fair value on a non-recurring $ 1,236 $ — $ — $ 1,236 As of December 31, 2022: Impaired loans - Commercial $ 1,028 $ — $ — $ 1,028 Impaired loans - SBA 222 — — 222 Total assets measured at fair value on a non-recurring $ 1,250 $ — $ — $ 1,250 The fair value of individually evaluated 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. Level 3 fair value measurement includes other real estate owned that has been measured at fair value upon transfer to foreclosed assets and loans collateralized by real property and other business asset collateral where a specific reserve has been established or a charge-off
