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 months ended March 31, 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 March 31, 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. Three months ended March 31, (Dollars in thousands, except per share data) 2023 2022 Net income available to common shareholders $ 5,451 $ 3,673 Weighted average basic common shares outstanding 8,339,080 8,276,761 Add: dilutive potential common shares 152,987 116,041 Weighted average diluted common shares outstanding 8,492,067 8,392,802 Basic earnings per share $ 0.65 $ 0.44 Diluted earnings per share $ 0.64 $ 0.44 Adoption of New Accounting Standards and Related Accounting Policies On January 1, 2023, the Company adopted ASU 2022-02, Financial Instruments—Credit Losses (Topic 326) 310-40, Receivables—Troubled 326-20, Financial On January 1, 2023, the Company adopted ASU 2016-13 held-to-maturity off-balance The Company adopted ASC 326, and all related subsequent amendments thereto, using the modified retrospective approach for all financial assets measured at amortized cost and off-balance The following accounting policies have been updated/implemented in connection with the adoption of CECL and should be read in conjunction with the significant accounting policies contained in our 2022 Form 10-K • Allowance for Credit Losses on Loans The ACL on loans represents the Company’s estimate of expected lifetime credit losses for its loans at the time of origination or acquisition and is maintained at a level deemed appropriate by management to provide for expected lifetime credit losses in the portfolio as of the date of the consolidated statements of financial condition. 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 March 31, 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.

At the time of adoption, the Company had no available for sale securities that required an allowance for credit losses under ASC 326, and had held to maturity securities that required an allowance for credit losses of $110,000. The allowance for credit losses pertained primarily to corporate bonds and was presented as a reduction to held to maturity securities outstanding. During the first quarter of 2023, there were no charge-offs or recoveries of securities and no additional provision for credit losses was required. At March 31, 2023, the Company had no securities held to maturity that were past due 30 days or more as to principal or interest payments, nor did the Company have any securities held to maturity that were classified as non-accrual. The Company did not purchase any investment securities during the three months ended March 31, 2023. The Company purchased 7 available for sale securities for $34.2 million and 10 held to maturity securities for $40.8 million during the three months ended March 31, 2022. The Company did not sell any investment securities during the three months ended March 31, 2023 and 2022. During the first quarter of 2022, the Company re-designated re-designated Net unrealized losses on available for sale investment securities totaling $1.5 million were recorded, net of deferred tax assets, as accumulated other comprehensive income within shareholders’ equity at March 31, 2023. Net unrealized gains on available for sale investment securities totaling $1.9 million were recorded, net of deferred tax liabilities, as accumulated other comprehensive income within shareholders’ equity at December 31, 2022. The following table summarizes unrealized losses for investment securities at March 31, 2023 and December 31, 2022 aggregated by major security type and length of time in a continuous unrealized loss position. Investment securities at March 31, 2023 reflect the disclosure requirements required by the Company’s adoption of ASC 326, and investment securities at December 31, 2022 are presented based upon prior accounting standards.

At December 31, 2022 the Company’s investment security portfolio consisted of 60 securities, 55 of which were in an 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 determined that there was no expected credit loss at March 31, 2023 and did not consider any investments to be other-than-temporarily impaired at December 31, 2022.

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.

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 weakness that deserves 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 institution’s credit position at some future date. Special Mention assets are not adversely classified and do not expose an institution to sufficient risk to warrant adverse classification. Substandard: Substandard credits are assets 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 March 31, 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 unadjusted for selling costs as appropriate. As of March 31, 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 collateral dependent. The following table reflects the evaluation methodology applied to gross loans by portfolio segment and the related allowance for credit losses as of March 31, 2023 and allowance for loan losses as of December 31, 2022 under ASC 326 and the previous accounting standard, respectively.

There was no interest recognized on a cash-basis on loans individually evaluated for expected credit losses/impairment during the three months ended March 31, 2023 and 2022 under ASC 326 and the previous accounting standard, respectively. Modifications Made to Borrowers Experiencing Financial Difficulty The allowance for credit losses incorporates an estimate of lifetime expected credit losses and is recorded on each asset upon asset origination or acquisition. 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. At March 31, 2023 and December 31, 2022, the Company had no recorded investments or commitments related to loans with terms that had been modified to borrowers experiencing financial difficulties. Additionally, the Company had no loan modifications with a subsequent payment default within twelve months following the modification during the three months ended March 31, 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 March 31, 2023 and December 31, 2022, the Company had outstanding unfunded commitments for loans of approximately $592.4 million and $644.1 million, respectively.

Fair Value Measurements

Fair Value Measurements	3 Months Ended

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 March 31, 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 March 31, 2023: Financial assets: Cash and cash equivalents $ 213,925 $ 213,925 $ — $ — $ 213,925 Investment securities: Available for sale 46,240 — 46,240 — 46,240 Held to Maturity 107,529 89,136 7,391 96,527 Loans, net 1,603,646 — — 1,546,878 1,546,878 Accrued interest receivable 8,340 — 884 7,456 8,340 Financial liabilities: Deposits $ 1,717,610 $ 1,388,313 $ 329,217 $ — $ 1,717,530 Other borrowings 75,000 — — 75,000 75,000 Subordinated debt 54,186 — — 48,943 48,943 Accrued interest payable 2,365 — 2,259 106 2,365 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 Other borrowings — — — — — Subordinated debt 54,152 — — 49,027 49,027 Accrued interest payable 1,678 — 1,007 671 1,678 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. 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 March 31, 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 considering recent trading activity of similar instruments in market which can be inactive and accordingly are classified within in the Level 3 classification. Junior Subordinated Debt Securities - 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.
