Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of Presentation | The consolidated financial statements include the accounts of Bank of Marin Bancorp (“Bancorp”), a bank holding company, and its wholly-owned bank subsidiary, Bank of Marin (the “Bank”), a California state-chartered commercial bank. References to “we,” “our,” “us” mean Bancorp and the Bank that are consolidated for financial reporting purposes. The accompanying unaudited consolidated interim financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information and note disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles ("GAAP") have been condensed or omitted pursuant to those rules and regulations. Although we believe that the disclosures are adequate and the information presented is not misleading, we suggest that these interim financial statements be read in conjunction with the annual financial statements and the notes thereto included in our 2019 Annual Report on Form 10-K. In the opinion of Management, the unaudited consolidated financial statements reflect all adjustments, which are necessary for a fair presentation of the consolidated financial position, the results of operations, changes in comprehensive income, changes in stockholders’ equity, and cash flows for the periods presented. All material intercompany transactions have been eliminated. The results of these interim periods may not be indicative of the results for the full year or for any other period. The NorCal Community Bancorp Trust II (the "Trust") was formed for the sole purpose of issuing trust preferred securities. Bancorp is not considered the primary beneficiary of the Trust (a variable interest entity), therefore the Trust is not consolidated in our consolidated financial statements, but rather the subordinated debenture is shown as a liability on our consolidated statements of condition. Bancorp's investment in the securities of the Trust is accounted for under the equity method and is included in interest receivable and other assets on the consolidated statements of condition. Refer to Note 6, Borrowings, for additional information on the subordinated debenture due to NorCal Community Bancorp Trust II.
Earnings Per Share | Basic earnings per share (“EPS”) are calculated by dividing net income by the weighted average number of common shares outstanding during each period, excluding unvested restricted stock awards. Diluted EPS are calculated using the weighted average number of potentially dilutive common shares. The number of potentially dilutive common shares included in the quarterly diluted EPS is computed using the average market prices during the three months included in the reporting period under the treasury stock method. The number of potentially dilutive common shares included in year-to-date diluted EPS is a year-to-date weighted average of potentially dilutive common shares included in each quarterly diluted EPS computation. In computing diluted EPS, we exclude anti-dilutive shares such as options whose exercise prices exceed the current common stock price, as they would not reduce EPS under the treasury method. We have two forms of outstanding common stock: common stock and unvested restricted stock awards. Holders of unvested restricted stock awards receive non-forfeitable dividends at the same rate as common shareholders and they both share equally in undistributed earnings. Under the two-class method, the difference in EPS is nominal for these participating securities.
Recently Adopted and Issued Accounting Standards | Accounting Standards Adopted in 2020 In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in this ASU remove, modify, and add disclosure requirements for the fair value reporting of assets and liabilities. The modifications and additions relate to Level 3 fair value measurements at the end of the reporting period. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Entities should disclose and describe the range and weighted-average of significant unobservable inputs used to develop Level 3 fair value measurements. We adopted this ASU prospectively effective January 1, 2020. As the ASU’s requirements only relate to disclosures, the amendments did not impact our financial condition or results of operations. Refer to Note 3, Fair Value of Assets and Liabilities, for additional disclosures. In August 2018, the FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. This standard aligns the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software regardless of whether they convey a license to the hosted software. The accounting for the service element of a hosting arrangement that is a service contract is not affected by this ASU. The amendments are effective for public business entities for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. An entity has the option to apply amendments in the ASU either retrospectively or prospectively to all implementation costs incurred after the date of adoption. We adopted this ASU prospectively on January 1, 2020, which did not impact our financial condition and results of operations. Accounting Standards Not Yet Adopted In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The standard replaces the "incurred loss" model with a "current expected credit loss" ("CECL") model. The CECL model applies to estimated credit losses on loans receivable, held-to-maturity debt securities, unfunded loan commitments, and certain other financial assets measured at amortized cost. The CECL model is based on lifetime expected losses, rather than incurred losses, and requires the recognition of credit loss expense in the consolidated statement of income and a related allowance for credit losses on the consolidated statement of condition at the time of origination or purchase of a loan receivable or held-to-maturity debt security. In addition, the CECL standard modifies the accounting for purchased loans and requires that an allowance for credit losses be established at the date of acquisition. However, for purchased financial assets with a more-than-insignificant amount of credit deterioration since origination (“PCD assets”) that are measured at amortized cost, the initial allowance for credit losses is added to the purchase price rather than being reported as a credit loss expense. Subsequent changes in the allowance for credit losses on PCD assets are recognized through credit loss expense. Under ASU 2016-13, available-for-sale debt securities are evaluated for impairment if fair value is less than amortized cost. Estimated credit losses are recorded through a credit loss expense and an allowance, rather than a write-down of the investment. Changes in fair value that are not credit-related will continue to be recorded in other comprehensive income. The ASU also expands the disclosure requirements regarding assumptions, models, and methods for estimating the allowance for credit losses. In addition, entities will disclose the amortized cost balance for each class of financial asset by credit quality indicator, disaggregated by the year of origination. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. However, in accordance with the accounting relief provisions of the Coronavirus Aid, Relief and Economic Security ("CARES") Act passed in March 2020, we postponed the adoption of the CECL standard. Implementation is delayed until the end of the national emergency or December 31, 2020, whichever occurs first. Early CECL implementation activities focused on, among other things, capturing and validating data, segmenting the loan portfolio, evaluating various credit loss estimation methodologies, sourcing tools to forecast future economic conditions, running multiple loan loss driver analyses that correlate our credit loss experience with one or more economic factors, and evaluating the qualitative factor framework and assumptions. Based on these activities, we determined that our primary credit loss methodology will utilize a discounted cash flow approach that considers the probability of default and loss given default. Ongoing implementation activities included refining forecast methodologies, running parallel calculations, evaluating and validating results, and documenting internal controls. The Bank has continued to run the CECL model in parallel with the incurred loss model and will adopt the CECL standard as of December 31, 2020. Upon adoption of the CECL standard, we will record a cumulative adjustment to retained earnings in our financial statements, net of taxes, based on economic forecasts and other assumptions as of January 1, 2020. That adjustment will result in an increase to our allowance for credit losses of approximately $1.6 million and an increase to the allowance for off-balance sheet commitments of approximately $122 thousand. These adjustments do not include the subsequent COVID-19 pandemic-related impact. Upon adoption on December 31, 2020, we will recognize the difference between the allowance for credit losses calculated under the CECL model as of December 31, 2020 and the allowance for credit losses calculated under the incurred loss model as of September 30, 2020 as a provision for credit losses and a provision for credit losses on off-balance sheet commitments, as applicable. Based on information available at this time, we do not expect the fourth quarter provision for credit losses to exceed 10% of the September 30, 2020 allowance for credit losses. However, the exact amount will depend on certain forecasts, such as the California unemployment rate, and other assumptions available as of December 31, 2020, which could differ significantly from present levels. In April 2019, the FASB issued ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments that clarifies and improves areas of guidance related to recently issued standards. The provisions of this ASU under Topic 326 will be evaluated in conjunction with the adoption of ASU 2016-13, however, we do not expect it to have a material impact on our financial condition and results of operations. All other provisions under this ASU were adopted as of January 1, 2020 and did not impact our financial condition and results of operations. In May 2019, the FASB issued ASU No. 2019-05, Financial Instruments - Credit Losses (Topic 326): Targeted Transition Relief. This ASU allows an option for entities to irrevocably elect the fair value option on an instrument-by-instrument basis for eligible financial assets measured at amortized cost basis upon adoption of the credit loss standards. This amendment provides relief for those entities electing the fair value option on newly originated or purchased financial assets, while maintaining existing similar financial assets at amortized cost, avoiding the requirement to maintain dual measurement methods for similar assets. The fair value option does not apply to held-to-maturity debt securities. The effective date for this ASU is the same as for ASU 2016-13, as discussed above. We will evaluate this ASU in conjunction with the adoption of ASU 2016-13 to determine its impact on our financial condition and results of operations. However, at this time we do not expect to elect the fair value option for our financial assets. In November 2019, the FASB issued ASU No. 2019-11, Codification Improvements to Topic 326, Financial Instruments - Credit Losses. This ASU, among other narrow-scope improvements, clarifies guidance around how to report expected recoveries. “Expected recoveries” describes a situation in which an organization recognizes a full or partial write-off of the amortized cost basis of a financial asset, but then later determines that the amount written off, or a portion of that amount, will in fact be recovered. This ASU permits organizations to record expected recoveries on PCD assets. Additionally, this ASU reinforces existing guidance that prohibits organizations from recording negative allowances for available-for-sale debt securities. ASU 2019-11 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The amendments should be applied on a modified retrospective basis by means of a cumulative-effect adjustment to the opening retained earnings balance in the statement of financial position as of the date of adoption. The effective date for this ASU is the same as for ASU 2016-13, as discussed above. We will evaluate this ASU in conjunction with the adoption of ASU 2016-13 to determine its impact on our financial condition and results of operations. Accounting Standards Not Yet Effective In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This ASU is intended to reduce the cost and complexity related to accounting for income taxes by removing certain exceptions to the guidance in Topic 740 related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and simplifying aspects of the accounting for franchise taxes and enacted changes in tax laws or rates. This ASU is effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. Early adoption is permitted. As this ASU is narrow in scope and applicability to us will likely be minimal, we do not expect that the ASU will have a material impact on our financial condition or results of operations. In January 2020, the FASB issued ASU No. 2020-01, Investments - Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) - Clarifying the Interactions between Topic 321, Topic 323, and Topic 815. Among other things, this ASU clarifies that a company should consider observable transactions that require a company to either apply or discontinue the equity method of accounting under Topic 323, for the purposes of applying the measurement alternative in accordance with Topic 321. This ASU is effective for fiscal years beginning after December 15, 2020. Early adoption is permitted. ASU No. 2020-01 should be applied prospectively at the beginning of the interim period that includes adoption. We do not expect that the ASU will have a material impact on our financial condition or results of operations. In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848). The amendments in this ASU are elective and provide optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform. The amendments in this ASU provide optional expedients and exceptions for applying generally accepted accounting principles (GAAP) to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The amendments in this ASU may be elected as of March 12, 2020 through December 31, 2022. An entity may choose to elect the amendments in this update at an interim period subsequent to March 12, 2020 with adoption methods varying based on transaction type. We have not elected to apply these amendments, however, we will assess the applicability of the ASU to us and continue to monitor guidance for reference rate reform from FASB and its impact on our financial condition and results of operations. In October 2020, the FASB issued ASU No. 2020-08, Codification Improvements to Subtopic 310-20, Receivables—Nonrefundable Fees and Other Costs. This ASU was issued as part of the Board's ongoing project to improve codification or correct unintended application. This ASU adds clarification to ASU 2017-08, which the Bank early adopted in 2017, and delineates whether an entity with callable debt securities that have multiple call dates should amortize the amount above that which is repayable, to the next call date. This ASU is effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years, on a prospective basis. Early adoption is not permitted. As this ASU is narrow in scope and for clarification purposes, we do not expect this ASU will have a material impact on our financial condition and results of operations.
Fair Value Hierarchy and Fair Value Measurement | We group our assets and liabilities that are measured at fair value in three levels within the fair value hierarchy, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are: Level 1: Valuations are based on unadjusted quoted prices in active markets for identical assets or liabilities. Level 2: Valuations are based on quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-based valuations for which all significant assumptions are observable or can be corroborated by observable market data. Level 3: Valuations are based on unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Values are determined using pricing models and discounted cash flow models and may include significant Management judgment and estimation. Available-for-sale securities are recorded at fair value on a recurring basis. When available, quoted market prices (Level 1) are used to determine the fair value of available-for-sale securities. If quoted market prices are not available, we obtain pricing information from a reputable third-party service provider, who may utilize valuation techniques that use current market-based or independently sourced parameters, such as bid/ask prices, dealer-quoted prices, interest rates, benchmark yield curves, prepayment speeds, probability of default, loss severity and credit spreads (Level 2). Level 2 securities include obligations of state and political subdivisions, U.S. agencies or government-sponsored agencies' debt securities, mortgage-backed securities, government agency-issued, privately-issued collateralized mortgage obligations, and corporate bonds.Held-to-maturity securities may be written down to fair value as a result of other-than-temporary impairmentOn a recurring basis, derivative financial instruments are recorded at fair value, which is based on the income approach using observable Level 2 market inputs, reflecting market expectations of future interest rates as of the measurement date. Standard valuation techniques are used to calculate the present value of the future expected cash flows assuming an orderly transaction. Valuation adjustments may be made to reflect both our own credit risk and the counterparties’ credit risk in determining the fair value of the derivatives. Level 2 inputs for the valuations are limited to observable market prices for London Interbank Offered Rate ("LIBOR") and Overnight Index Swap ("OIS") rates (for the very short term), quoted prices for LIBOR futures contracts, observable market prices for LIBOR and OIS swap rates, and one-month and three-month LIBOR basis spreads at commonly quoted intervals. Mid-market pricing of the inputs is used as a practical expedient in the fair value measurements. We project spot rates at reset days specified by each swap contract to determine future cash flows, then discount to present value using OIS curves as of the measurement date. When the value of any collateral placed with counterparties is less than the interest rate derivative liability, a credit valuation adjustment ("CVA") is applied to reflect the credit risk we pose to counterparties. We have used the spread between the Standard & Poor's BBB rated U.S. Bank Composite rate and LIBOR for the closest maturity term corresponding to the duration of the swaps to derive the CVA. A similar credit risk adjustment, correlated to the credit standing of the counterparty, is made when collateral posted by the counterparty does not fully cover their liability to us. For further discussion on our methodology in valuing our derivative financial instruments, refer to Note 9, Derivative Financial Instruments and Hedging Activities.Certain financial assets may be measured at fair value on a non-recurring basis. These assets are subject to fair value adjustments that result from the application of the lower of cost or fair value accounting or write-downs of individual assets, such as impaired loans that are collateral dependent and other real estate owned ("OREO").
Finance, Loan and Lease Receivables, Held-for-investment, Allowance and Nonperforming Loans | We generally make commercial loans to established small and mid-sized businesses to provide financing for their growth and working capital needs, equipment purchases and acquisitions. Management examines historical, current, and projected cash flows to determine the ability of the borrower to repay obligations as agreed. Commercial loans are made based primarily on the identified cash flows of the borrower and secondarily on the underlying collateral and guarantor support. The cash flows of borrowers, however, may not occur as expected, and the collateral securing these loans may fluctuate in value. Most commercial and industrial loans are secured by the assets being financed, such as accounts receivable and inventory, and typically include personal guarantees. We target stable businesses with guarantors who provide additional sources of repayment and have proven to be resilient in periods of economic stress. Pursuant to the CARES Act, the Bank funded over 1,800 loans to eligible small businesses and non-profit organizations who participated in the Paycheck Protection Program (“PPP”) administered by the U.S. Small Business Administration (“SBA”). PPP loans have terms of two to five years and earn interest at 1%. In addition, the Bank received a fee of 1%-5% from the SBA depending on the loan amount, which was netted with loan origination costs and amortized into interest income under the effective yield method over the contractual life of the loan. The recognition of fees and costs is accelerated when the loan is forgiven by the SBA and/or paid off prior to maturity. PPP loans are fully guaranteed by the SBA and are expected to be forgiven by the SBA if they meet the requirements of the program. PPP loans totaling $301.7 million at September 30, 2020 are included in commercial and industrial loan balances. The Bank ended its origination of new PPP loans on June 30, 2020. On June 5, 2020, the PPP Flexibility Act was signed into law that modified, among other things, rules governing the PPP payment deferral period. In October 2020, due to the continued delay in the PPP forgiveness process, the Bank modified the first payment due dates for PPP loans that originated prior to June 5, 2020 and extended the payment deferral period from six to sixteen months. The extended payment deferral period will affect the timing over which the accretion of PPP net loan origination fees are recognized. Commercial real estate loans are subject to underwriting standards and processes similar to commercial loans discussed above. We underwrite these loans to be repaid from cash flow and to be supported by real property collateral. Underwriting standards for commercial real estate loans include, but are not limited to, debt coverage and loan-to-value ratios. Furthermore, a large majority of our loans are guaranteed by the owners of the properties. Conditions in the real estate markets or in the general economy may adversely affect our commercial real estate loans. In the event of a vacancy, we expect guarantors to carry the loans until they find a replacement tenant. The owner's substantial equity investment provides a strong economic incentive to continue to support the commercial real estate projects. As such, we have generally experienced a relatively low level of loss and delinquencies in this portfolio. Construction loans are generally made to developers and builders to finance construction, renovation and occasionally land acquisitions in anticipation of near-term development. Construction loans include interest reserves that are used for the payment of interest during the development and marketing periods and are capitalized as part of the loan balance. When a construction loan is placed on nonaccrual status before the depletion of the interest reserve, we apply the interest funded by the interest reserve against the loan's principal balance. These loans are underwritten after evaluation of the borrower's financial strength, reputation, prior track record, and independent appraisals. We monitor all construction projects to determine whether they are on schedule, completed as planned and in accordance with the approved construction budgets. Significant events can affect the construction industry, including: the inherent volatility of real estate markets and vulnerability to delays due to weather, change orders, inability to obtain construction permits, labor or material shortages, and price changes. Estimates of construction costs and value associated with the completed project may be inaccurate. Repayment of construction loans is largely dependent on the ultimate success of the project. Consumer loans primarily consist of home equity lines of credit, other residential loans and floating homes, along with a small number of installment loans. Our other residential loans include tenancy-in-common fractional interest loans ("TIC") located almost entirely in San Francisco County. We originate consumer loans utilizing credit score information, debt-to-income ratio and loan-to-value ratio analysis. Diversification among consumer loan types, coupled with relatively small loan amounts that are spread across many individual borrowers, mitigates risk. We do not originate sub-prime residential mortgage loans, nor is it our practice to underwrite loans commonly referred to as "Alt-A mortgages," the characteristics of which are reduced documentation, borrowers with low FICO scores or collateral with high loan-to-value ratios. We use a risk rating system to evaluate asset quality, and to identify and monitor credit risk in individual loans, and in the loan portfolio. Our definitions of “Special Mention” risk graded loans, or worse, are consistent with those used by the Federal Deposit Insurance Corporation ("FDIC"). Our internally assigned grades are as follows: Pass and Watch: Loans to borrowers of acceptable or better credit quality. Borrowers in this category demonstrate fundamentally sound financial positions, repayment capacity, credit history, and management expertise. Loans in this category must have an identifiable and stable source of repayment and meet the Bank’s policy regarding debt-service-coverage ratios. These borrowers are capable of sustaining normal economic, market or operational setbacks without significant financial consequences. Negative external industry factors are generally not present. The loan may be secured, unsecured or supported by non-real estate collateral for which the value is more difficult to determine and/or marketability is more uncertain. This category also includes “Watch” loans, where the primary source of repayment has been delayed. “Watch” is intended to be a transitional grade, with either an upgrade or downgrade within a reasonable period. Special Mention: Potential weaknesses that deserve close attention. If left uncorrected, those potential weaknesses may result in deterioration of the payment prospects for the asset. Special Mention assets do not present sufficient risk to warrant adverse classification. Substandard: Inadequately protected by either the current sound worth and paying capacity of the obligor or the collateral pledged, if any. A Substandard asset has a well-defined weakness or weaknesses that jeopardize(s) the liquidation of the debt. Substandard assets are characterized by the distinct possibility that we will sustain some loss if such weaknesses or deficiencies are not corrected. Well-defined weaknesses include adverse trends or developments of the borrower’s financial condition, managerial weaknesses and/or significant collateral deficiencies. Doubtful: Critical weaknesses that make collection or liquidation in full improbable. There may be specific pending events that work to strengthen the asset; however, the amount or timing of the loss may not be determinable. Pending events generally occur within one year of the asset being classified as Doubtful. Examples include: merger, acquisition, or liquidation; capital injection; guarantee; perfecting liens on additional collateral; and refinancing. Such loans are placed on non-accrual status and usually are collateral-dependent. We regularly review our credits for accuracy of risk grades whenever we receive new information. Borrowers are generally required to submit financial information at regular intervals. Typically, commercial borrowers with lines of credit are required to submit financial information with reporting intervals ranging from monthly to annually depending on credit size, risk and complexity. In addition, investor commercial real estate borrowers with loans exceeding a certain dollar threshold are usually required to submit rent rolls or property income statements annually. We monitor construction loans monthly. We review home equity and other consumer loans based on delinquency. We also review loans graded “Watch” or worse, regardless of loan type, no less than quarterly.
Troubled Debt Restructuring | Our loan portfolio includes certain loans modified in a troubled debt restructuring (“TDR”), where we have granted economic concessions to borrowers experiencing financial difficulties. These concessions typically result from our loss mitigation activities and could include reductions in the interest rate, payment extensions, forgiveness of principal, forbearance or other actions. TDRs on non-accrual status at the time of restructure may be returned to accruing status after Management considers the borrower’s sustained repayment performance for a reasonable period, generally nine months, and obtains reasonable assurance of repayment and performance. We may remove a loan from TDR designation if it meets all of the following conditions: •The loan is subsequently refinanced or restructured at current market interest rates and the new terms are consistent with the treatment of creditworthy borrowers under regular underwriting standards; •The borrower is no longer considered to be in financial difficulty; •Performance on the loan is reasonably assured; and •Existing loan did not have any forgiveness of principal or interest. The same Management level that approved the loan classification upgrade must approve the removal of TDR status.

- Definition Describes an entity's accounting policy and methodology for estimating its allowance for loan and lease losses, and its accounting policy for nonperforming loans. The description identifies the factors that influenced management of the entity in establishing the level of the allowance (for example, historical losses and existing economic conditions) and also may include discussion of the risk elements relevant to particular categories of receivables. The disclosure also may describe any liability the entity has recorded for off-balance sheet credit losses and may include the basis for determining each element of the allowance for loan and lease losses. The disclosure also could discuss the entity's policy for (1) placing loans on nonaccrual status (or discontinuing accrual of interest) and recording payments received on nonaccrual loans, and the policy for resuming accrual of interest, (2) charging-off uncollectible loans, and (3) determining past due or delinquency status (that is, whether past due status is based on how recently payments have been received or contractual terms). + References Reference 1: http://fasb.org/us-gaap/role/ref/legacyRef -Publisher FASB -Name Accounting Standards Codification -Topic 310 -SubTopic 10 -Section 50 -Paragraph 6 -URI http://asc.fasb.org/extlink&oid=121611835&loc=d3e5093-111524 Reference 2: http://fasb.org/us-gaap/role/ref/legacyRef -Publisher FASB -Name Accounting Standards Codification -Topic 235 -SubTopic 10 -Section 50 -Paragraph 3 -URI http://asc.fasb.org/extlink&oid=84158767&loc=d3e18780-107790 Reference 3: http://fasb.org/us-gaap/role/ref/legacyRef -Publisher FASB -Name Accounting Standards Codification -Topic 310 -SubTopic 10 -Section 50 -Paragraph 11B -Subparagraph (b) -URI http://asc.fasb.org/extlink&oid=121611835&loc=SL6953423-111524 Reference 4: http://fasb.org/us-gaap/role/ref/legacyRef -Publisher FASB -Name Accounting Standards Codification -Topic 310 -SubTopic 10 -Section 50 -Paragraph 9 -URI http://asc.fasb.org/extlink&oid=121611835&loc=d3e5144-111524 Reference 5: http://fasb.org/us-gaap/role/ref/legacyRef -Publisher FASB -Name Accounting Standards Codification -Topic 942 -SubTopic 210 -Section S99 -Paragraph 1 -Subparagraph (SX 210.9-03(7)) -URI http://asc.fasb.org/extlink&oid=120398452&loc=d3e534808-122878 + Details
