Accounting Policies [Abstract]
Description of Business and Summary of Significant Accounting Policies	Note 1 - Description of Business and Summary of Significant Accounting Policies Nature of operations - Coastal Financial Corporation (Corporation or Company) is a registered bank holding company whose wholly owned subsidiary is Coastal Community Bank (Bank). The Company is a Washington state corporation that was organized in 2003. The Bank was incorporated and commenced operations in 1997 and is a Washington state-chartered commercial bank and Federal Reserve System (Federal Reserve) state member bank. The Company provides a full range of banking services to small and medium-sized businesses, professionals, and individuals throughout the greater Puget Sound area through its 14 branches in Snohomish, Island, and King Counties, the Internet, and its mobile banking application. The Bank’s main branch and the headquarters of the Bank and Company are located in Everett, Washington. The Bank’s deposits are insured in whole or in part by the FDIC. The Bank’s loans and deposits are primarily within the greater Puget Sound area, and the Bank’s primary funding source is deposits from customers. The Bank is subject to regulation by the Federal Reserve and the Washington State Department of Financial Institutions Division of Banks. The Federal Reserve also has supervisory authority over the Company. Financial statement presentation - The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim reporting requirements and with instructions to Form 10-Q and Article 10 of Regulation S-X, and therefore do not include all the information and notes included in the annual consolidated financial statements in conformity with GAAP. These interim condensed consolidated financial statements and accompanying notes should be read in conjunction with the Company’s audited consolidated financial statements and accompanying notes included in the Company’s Annual report on Form 10-K as filed with the U.S. Securities and Exchange Commission (SEC) on March 28, 2019. Operating results for the three and nine months ended September 30, 2019 are not necessarily indicative of the results that may be expected for future periods. Amounts presented in the consolidated financial statements and footnote tables are rounded and presented in thousands of dollars except per-share amounts, which are presented in dollars. In the narrative footnote discussion, amounts are rounded to thousands and presented in dollars. In management’s opinion, all accounting adjustments necessary to accurately reflect the financial position and results of operations on the accompanying consolidated financial statements have been made. These adjustments include normal and recurring accruals considered necessary for a fair and accurate presentation. Principles of consolidation - The consolidated financial statements include the accounts of the Company and the Bank. All significant intercompany accounts have been eliminated in consolidation. Business Segments - The Company is managed by legal entity and not by lines of business. The entity’s primary business is that of a traditional banking institution, gathering deposits and originating loans for portfolio in its market areas. The Bank offers a wide variety of deposit products to its customers. Lending activities include the origination of real estate, commercial and industrial, and consumer loans. Interest income on loans is the Company’s primary source of revenue, and is supplemented by interest income on deposits with other banks, interest income from investment securities, deposit service charges, and other service provided activities. The Company has determined that its current business and operations consist of a single reporting segment and, therefore, segment disclosures are not required. 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 financial statements and the reported amounts of revenues and expenses during the reporting period. Management believes that its critical accounting policies include determining the allowance for loan losses, the fair value of the Company’s investment securities, deferred tax assets, and financial instruments. Actual results could differ significantly from those estimates. Subsequent Events - The Company has evaluated events and transactions subsequent to September 30, 2019 for potential recognition or disclosure. Accounting policies – Our complete accounting policies are described in Note 1, summary of significant accounting policies of the Company’s audited consolidated financial statements as of and for the years ended December 31, 2018 and 2017 included in the Company’s Annual Report Form 10-K filed with the SEC on March 28, 2019. Reclassifications - Certain amounts reported in prior quarters' consolidated financial statements have been reclassified to conform to the current presentation with no effect on stockholders’ equity or net income.

Information pertaining to securities with gross unrealized losses at the dates indicated, aggregated by investment category and length of time that individual securities have been in a continuous loss position, follows: Less Than 12 Months 12 Months or Greater Total Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses (dollars in thousands) September 30, 2019 Available-for-sale U.S. Treasury securities $ 19,959 $ (10 ) $ 4,939 $ (58 ) $ 24,898 $ (68 ) U.S. Government agencies - - 2,993 (8 ) 2,993 (8 ) U.S. Agency collateralized mortgage obligations - - - - - - Municipals - - - - - - U.S. Agency residential mortgage-backed securities - - - - - - Total available-for-sale securities 19,959 (10 ) 7,932 (66 ) 27,891 (76 ) Held-to-maturity U.S. Agency residential mortgage-backed securities 3,144 (24 ) 1,198 (11 ) 4,342 (35 ) Total investment securities $ 23,103 $ (34 ) $ 9,130 $ (77 ) $ 32,233 $ (111 ) December 31, 2018 Available-for-sale U.S. Treasury securities $ - $ - $ 33,241 $ (1,590 ) $ 33,241 $ (1,590 ) U.S. Government agencies - - 2,957 (43 ) 2,957 (43 ) U.S. Agency collateralized mortgage obligations - - 169 (3 ) 169 (3 ) Municipals - - 255 (4 ) 255 (4 ) U.S. Agency residential mortgage-backed securities 38 (1 ) - - 38 (1 ) Total available-for-sale securities 38 (1 ) 36,622 (1,640 ) 36,660 (1,641 ) Held-to-maturity U.S. Agency residential mortgage-backed securities - - 1,205 (57 ) 1,205 (57 ) Total investment securities $ 38 $ (1 ) $ 37,827 $ (1,697 ) $ 37,865 $ (1,698 ) At September 30, 2019 and December 31, 2018, there were seven and 12 securities in an unrealized loss position, respectively. Unrealized losses have not been recognized into income because management does not intend to sell and does not expect that it will be required to sell the investments. The decline is largely due to changes in market conditions and interest rates, rather than credit quality. The fair value is expected to recover as the underlying securities in the portfolio approach maturity date and market conditions improve. The Company does not consider these securities to be other than temporarily impaired at September 30, 2019 and December 31, 2018.

Loans and Allowance for Loan Losses	Note 4 - Loans and Allowance for Loan Losses The composition of the loan portfolio is as follows as of the periods indicated: September 30, December 31, 2019 2018 (dollars in thousands) Commercial and industrial loans $ 105,634 $ 90,390 Real estate loans: Construction, land, and land development 86,919 64,045 Residential real estate 100,818 94,745 Commercial real estate 578,607 515,959 Consumer and other loans 3,720 3,584 Gross loans receivable 875,698 768,723 Net deferred origination fees and premiums (1,586 ) (824 ) Loans receivable $ 874,112 $ 767,899 Included in consumer and other loans are overdrafts of $24,000 and $36,000 at September 30, 2019 and December 31, 2018, respectively. The Company has pledged loans totaling $168,175,000 and $155,029,000 at September 30, 2019 and December 31, 2018, respectively, for borrowing lines at the FHLB and Federal Reserve Bank (FRB). The balance of Small Business Administration (SBA) and United States Department of Agriculture (USDA) loans and participations serviced for others totaled $22,446,000 and $24,878,000 at September 30, 2019 and December 31, 2018, respectively. The Company, at times, purchases individual loans at fair value as of the acquisition date. Purchased loans with remaining balances totaled $33,696,000 and $45,368,000 as of September 30, 2019 and December 31, 2018, respectively. Unamortized premiums totaled $533,000 and $701,000 as of September 30, 2019 and December 31, 2018, respectively, and are amortized into interest income over the life of the loans. The Company has purchased participation loans with remaining balances totaling $36,151,000 and $36,561,000 as of September 30, 2019 and December 31, 2018, respectively. The following is a summary of the Company’s loan portfolio segments: Commercial and industrial loans - Commercial and industrial loans are secured by business assets including inventory, receivables and machinery and equipment of businesses located generally in our primary market area. Loan types include revolving lines of credit, term loans, and loans secured by liquid collateral such as cash deposits or marketable securities. We also issue letters of credit on behalf of our customers. Risk arises primarily due to the difference between expected and actual cash flows of the borrowers. In addition, the recoverability of the Company’s investment in these loans is also dependent on other factors primarily dictated by the type of collateral securing these loans. The fair value of the collateral securing these loans may fluctuate as market conditions change. In the case of loans secured by accounts receivable, the recovery of the Company’s investment is dependent upon the borrower’s ability to collect amounts due from its customers. Construction, land and land development loans - We originate loans for the construction of 1-4 family, multifamily, and Commercial Real Estate (CRE) properties in our market area. Construction loans are considered to have higher risks due to construction completion and timing risk, the ultimate repayment being sensitive to interest rate changes, government regulation of real property and the availability of long-term financing. Additionally, economic conditions may impact the Company’s ability to recover its investment in construction loans, as adverse economic conditions may negatively impact the real estate market, which could affect the borrower’s ability to complete and sell the project. Additionally, the fair value of the underlying collateral may fluctuate as market conditions change. We occasionally originate land loans for the purpose of facilitating the ultimate construction of a home or commercial building. The primary risks include the borrower’s ability to pay and the inability of the Company to recover its investment due to a material decline in the fair value of the underlying collateral. Residential real estate loans - Residential real estate loans include various types of loans for which the Company holds real property as collateral. Included in this segment are first lien single family loans, which we occasionally purchase to diversify our loan portfolio, and rental portfolios secured by one-to-four family homes. The primary risks of residential real estate loans include the borrower’s inability to pay, material decreases in the value of the collateral, and significant increases in interest rates which may make the loan unprofitable. Commercial real estate (includes owner occupied and nonowner occupied) loans - Commercial real estate loans include various types of loans for which the Company holds real property as collateral. The primary risks of commercial real estate loans include the borrower’s inability to pay, material decreases in the value of the collateralized real estate and significant increases in interest rates, which may make the real estate loan unprofitable. Commercial real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy. Consumer and other loans - We originate a limited number of consumer loans, generally for banking customers only, which consist primarily of home equity lines of credit, saving account secured loans, and auto loans. This loan category also includes overdrafts. Repayment of these loans is dependent on the borrower’s ability to pay and the fair value of the underlying collateral. The following table illustrates an age analysis of past due loans as of the dates indicated: 30-89 Days Past Due 90 Days or More Past Due Total Past Due Current Total Loans Recorded Investment 90 Days or More Past Due and Still Accruing (dollars in thousands) September 30, 2019 Commercial and industrial loans $ - $ 1,233 $ 1,233 $ 104,401 $ 105,634 $ - Real estate loans: Construction, land and land development - - - 86,919 86,919 - Residential real estate - 67 67 100,751 100,818 - Commercial real estate 420 - 420 578,187 578,607 - Consumer and other loans 6 - 6 3,714 3,720 - $ 426 $ 1,300 $ 1,726 $ 873,972 $ 875,698 $ - Less net deferred origination fees and premiums (1,586 ) Loans receivable $ 874,112 30-89 Days Past Due 90 Days or More Past Due Total Past Due Current Total Loans Recorded Investment 90 Days or More Past Due and Still Accruing (dollars in thousands) December 31, 2018 Commercial and industrial loans $ 171 $ 494 $ 665 $ 89,725 $ 90,390 $ - Real estate loans: Construction, land and land development 823 - 823 63,222 64,045 - Residential real estate - 72 72 94,673 94,745 - Commercial real estate - - - 515,959 515,959 - Consumer and other loans 2 - 2 3,582 3,584 - $ 996 $ 566 $ 1,562 $ 767,161 768,723 $ - Less net deferred origination fees and premiums (824 ) Loans receivable $ 767,899 A summary of information pertaining to impaired loans as of the period indicated: Unpaid Contractual Principal Balance Recorded Investment With No Allowance Recorded Investment With Allowance Total Recorded Investment Related Allowance (dollars in thousands) September 30, 2019 Commercial and industrial loans $ 1,463 $ 407 $ 826 $ 1,233 $ 230 Real estate loans: Residential real estate 73 67 - 67 - Total $ 1,536 $ 474 $ 826 $ 1,300 $ 230 December 31, 2018 Commercial and industrial loans $ 766 $ 493 $ - $ 493 $ - Real estate loans: Residential real estate 74 72 - 72 - Commercial real estate 1,491 1,261 - 1,261 - Total $ 2,331 $ 1,826 $ - $ 1,826 $ - The following tables summarize our average recorded investment and interest income recognized on impaired loans by loan class for the three and nine months ended September 30, 2019 and 2018: Three Months Ended September 30, 2019 September 30, 2018 Average Recorded Investment Interest Income Recognized Average Recorded Investment Interest Income Recognized (dollars in thousands) Commercial and industrial loans $ 1,406 $ - $ 995 $ 3 Real estate loans: Residential real estate 68 - 74 - Commercial real estate - - 1,284 - Total $ 1,474 $ - $ 2,353 $ 3 Nine Months Ended September 30, 2019 September 30, 2018 Average Recorded Investment Interest Income Recognized Average Recorded Investment Interest Income Recognized (dollars in thousands) Commercial and industrial loans $ 933 $ - $ 1,371 $ 28 Real estate loans: Construction, land and land development - - - - Residential real estate 71 - 306 5 Commercial real estate 315 - 1,296 - Total $ 1,319 $ - $ 2,973 $ 33 The Company grants restructurings in response to borrower financial difficulty, and generally provides for a temporary modification of loan repayment terms. The restructured loans on accrual status represent the only impaired loans accruing interest. In order for a restructured loan to be considered for accrual status, the loan’s collateral coverage generally will be greater than or equal to 100% of the loan balance, the loan is current on payments, and the borrower must either prefund an interest reserve or demonstrate the ability to make payments from a verified source of cash flow for an extended period of time, usually at least six months in duration. The following table presents troubled debt restructurings by accrual versus nonaccrual status and by loan class as of December 31, 2018. The troubled debt restructuring outstanding as of December 31, 2018 was paid off in the first quarter of 2019. Accrual Status Nonaccrual Status Total Restructured Loans (dollars in thousands) December 31, 2018 Commercial real estate $ - $ 1,261 $ 1,261 No loans were restructured in the nine months ended September 30, 2019 and September 30, 2018 that qualified as troubled debt restructurings. The Company has no commitments to loan additional funds to borrowers whose loans were classified as troubled debt restructurings at September 30, 2019, as there were no outstanding troubled debt restructurings at September 30, 2019. When loans are placed on nonaccrual status, all accrued interest is reversed from current period earnings. Payments received on nonaccrual loans are generally applied as a reduction to the loan principal balance. If the likelihood of further loss is removed, the Company will recognize interest on a cash basis only. Loans may be returned to accruing status if the Company believes that all remaining principal and interest is fully collectible and there has been at least six months of sustained repayment performance since the loan was placed on nonaccrual. An analysis of nonaccrual loans by category consisted of the following at the periods indicated: September 30, December 31, 2019 2018 (dollars in thousands) Commercial and industrial loans $ 1,233 $ 493 Real estate loans: Residential real estate 67 72 Commercial real estate - 1,261 Total nonaccrual loans $ 1,300 $ 1,826 Credit Quality and Credit Risk Federal regulations require that the Company periodically evaluate the risks inherent in its loan portfolio. In addition, the Company’s regulatory agencies have authority to identify problem loans and, if appropriate, require them to be reclassified. There are three classifications for problem loans: Substandard, Doubtful, and Loss. Substandard loans have one or more defined weaknesses and are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Doubtful loans have the weaknesses of loans classified as Substandard, with additional characteristics that suggest the weaknesses make collection or recovery in full after liquidation of collateral questionable on the basis of currently existing facts, conditions, and values. There is a high possibility of loss in loans classified as Doubtful. A loan classified as Loss is considered uncollectible and of such little value that continued classification of the credit as a loan is not warranted. If a loan or a portion thereof is classified as Loss, it must be charged-off, meaning the amount of the loss is charged against the allowance for loan losses, thereby reducing that reserve. The Company also classifies some loans as Watch or Other Loans Especially Mentioned (OLEM). Loans classified as Watch are performing assets and classified as pass credits but have elements of risk that require more monitoring than other performing loans and are reported in the Pass column in the following table. Loans classified as OLEM are assets that continue to perform but have shown deterioration in credit quality and require close monitoring. Loans by credit quality risk rating are as follows as of the periods indicated: Pass Other Loans Especially Mentioned Sub- Standard Doubtful Total (dollars in thousands) September 30, 2019 Commercial and industrial loans $ 97,923 $ 2,579 $ 5,132 $ - $ 105,634 Real estate loans: Construction, land, and land development 86,919 - - - 86,919 Residential real estate 100,333 418 67 - 100,818 Commercial real estate 575,895 2,712 - - 578,607 Consumer and other loans 3,720 - - - 3,720 $ 864,790 $ 5,709 $ 5,199 $ - 875,698 Less net deferred origination fees (1,586 ) Loans receivable $ 874,112 December 31, 2018 Commercial and industrial loans $ 84,859 $ 3,908 $ 1,623 $ - $ 90,390 Real estate loans: Construction, land, and land development 55,666 8,379 - - 64,045 Residential real estate 94,548 125 72 - 94,745 Commercial real estate 512,151 2,547 1,261 - 515,959 Consumer and other loans 3,584 - - 3,584 $ 750,808 $ 14,959 $ 2,956 $ - 768,723 Less net deferred origination fees (824 ) Loans receivable $ 767,899 Allowance for Loan Losses The Company’s allowance for loan losses (ALLL) covers estimated credit losses on individually evaluated loans that are determined to be impaired as well as estimated probable losses inherent in the remainder of the loan portfolio. The ALLL is prepared using the information provided by the Company’s credit review process together with data from peer institutions and economic information gathered from published sources. The loan portfolio is segmented into groups of loans with similar risk profiles. Each segment possesses varying degrees of risk based on the type of loan, the type of collateral, and the sensitivity of the borrower or industry to changes in external factors such as economic conditions. An estimated loss rate calculated the Company’s actual historical loss rates adjusted for current portfolio trends, economic conditions, and other relevant internal and external factors, is applied to each group’s aggregate loan balances. The following tables summarize the allocation of the ALLL, as well as the activity in the ALLL attributed to various segments in the loan portfolio, as of and for the three and nine months ended September 30, 2019: Commercial and Industrial Construction, Land, and Land Development Residential Real Estate Commercial Real Estate Consumer and Other Unallocated Total (dollars in thousands) Three months ended September 30, 2019 Balance, June 30, 2019 $ 2,482 $ 2,386 $ 1,814 $ 2,845 $ 67 $ 849 $ 10,443 Provision for loan losses or (recapture) 195 136 140 107 22 37 637 2,677 2,522 1,954 2,952 89 886 11,080 Loans charged-off (118 ) (75 ) - - (3 ) - (196 ) Recoveries of loans previously charged-off 2 - - - 2 - 4 Net (charge-offs) recoveries (116 ) (75 ) - - (1 ) - (192 ) Balance, September 30, 2019 $ 2,561 $ 2,447 $ 1,954 $ 2,952 $ 88 $ 886 $ 10,888 Nine months ended September 30, 2019 Balance, December 31, 2018 $ 2,039 $ 1,806 $ 1,647 $ 2,648 $ 77 $ 1,190 $ 9,407 Provision for loan losses or (recapture) 643 716 307 333 29 (304 ) 1,724 2,682 2,522 1,954 2,981 106 886 11,131 Loans charged-off (125 ) (75 ) - (29 ) (23 ) - (252 ) Recoveries of loans previously charged-off 4 - - - 5 - 9 Net (charge-offs) recoveries (121 ) (75 ) - (29 ) (18 ) - (243 ) Balance, September 30, 2019 $ 2,561 $ 2,447 $ 1,954 $ 2,952 $ 88 $ 886 $ 10,888 As of September 30, 2019 ALLL amounts allocated to Individually evaluated for impairment $ 230 $ - $ - $ - $ - $ - $ 230 Collectively evaluated for impairment 2,331 2,447 1,954 2,952 88 886 10,658 ALLL balance, September 30, 2019 $ 2,561 $ 2,447 $ 1,954 $ 2,952 $ 88 $ 886 $ 10,888 Loans individually evaluated for impairment $ 1,233 $ - $ 67 $ - $ - $ 1,300 Loans collectively evaluated for impairment 104,401 86,919 100,751 578,607 3,720 874,398 Loan balance, September 30, 2019 $ 105,634 $ 86,919 $ 100,818 $ 578,607 $ 3,720 $ 875,698 The following tables summarize the allocation of the ALLL, as well as the activity in the ALLL attributed to various segments in the loan portfolio, as of and for the three and nine months ended September 30, 2018: Commercial and Industrial Construction, Land, and Land Development Residential Real Estate Commercial Real Estate Consumer and Other Unallocated Total (dollars in thousands) Three Months Ended September 30, 2018 ALLL balance, June 30, 2018 $ 1,821 $ 1,238 $ 1,395 $ 2,303 $ 52 $ 1,731 $ 8,540 Provision for loan losses or (recapture) (10 ) 423 7 164 39 (115 ) 508 1,811 1,661 1,402 2,467 91 1,616 9,048 Loans charged-off - - - - (6 ) - (6 ) Recoveries of loans previously charged-off 1 - 65 - 3 - 69 Net (charge-offs) recoveries 1 - 65 - (3 ) - 63 ALLL balance, September 30, 2018 $ 1,812 $ 1,661 $ 1,467 $ 2,467 $ 88 $ 1,616 $ 9,111 Nine Months Ended September 30, 2018 ALLL balance, December 31, 2017 $ 1,864 $ 1,063 $ 1,343 $ 2,014 $ 43 $ 1,690 $ 8,017 Provision for loan losses or (recapture) 226 598 59 537 55 (74 ) 1,401 2,090 1,661 1,402 2,551 98 1,616 9,418 Loans charged-off (281 ) - - (84 ) (20 ) - (385 ) Recoveries of loans previously charged-off 3 - 65 - 10 - 78 Net (charge-offs) recoveries (278 ) - 65 (84 ) (10 ) - (307 ) ALLL balance, September 30, 2018 $ 1,812 $ 1,661 $ 1,467 $ 2,467 $ 88 $ 1,616 $ 9,111 Commercial and Industrial Construction, Land, and Land Development Residential Real Estate Commercial Real Estate Consumer and Other Unallocated Total (dollars in thousands) As of December 31, 2018 ALLL amounts allocated to Individually evaluated for impairment $ - $ - $ - $ - $ - $ - $ - Collectively evaluated for impairment 2,039 1,806 1,647 2,648 77 1,190 9,407 ALLL balance, December 31, 2018 $ 2,039 $ 1,806 $ 1,647 $ 2,648 $ 77 $ 1,190 $ 9,407 Loans individually evaluated for impairment $ 493 $ - $ 72 $ 1,261 $ - $ 1,826 Loans collectively evaluated for impairment 89,897 64,045 94,673 514,698 3,584 766,897 Loan balance, December 31, 2018 $ 90,390 $ 64,045 $ 94,745 $ 515,959 $ 3,584 $ 768,723

Leases

Leases [Abstract]
Leases	Note 6 - Leases The Company has committed to rent premises used in business operations under non-cancelable operating leases and determines if an arrangement meets the definition of a lease upon inception. The Company adopted the provisions of ASU 2016-02 (Topic 842) on January 1, 2019. Operating lease right-of-use (“ROU”) assets represent a right to use an underlying asset for the contractual lease term. Operating lease liabilities represent an obligation to make lease payments arising from the lease. Upon adoption, operating lease ROU assets totaling $9.4 million and operating lease liabilities totaling $9.6 million were recognized in our Unaudited Consolidated Balance Sheets for leases that existed at the adoption date, based on the present value of lease payments over the remaining lease term. ROU assets are further adjusted for lease incentives. Operating leases entered into after the adoption date will be recognized as an operating lease ROU asset and operating lease liability at the commencement date of the new lease. The Company’s leases do not provide an implicit interest rate, therefore the Company used its incremental collateralized borrowing rates commensurate with the underlying lease terms to determine the present value of operating lease liabilities. The weighted average discount rate used to discount operating lease liabilities at September 30, 2019 was 3.5%. The Company’s operating lease agreements contain both lease and non-lease components, which are generally accounted for separately. The Company’s lease agreements do not contain any residual value guarantees. Operating leases with terms of 12 months or less are not included in ROU assets and operating lease liabilities recorded in our consolidated balance sheets. Operating lease terms include options to extend when it is reasonably certain that the Company will exercise such options, determined on a lease-by-lease basis. During the third quarter of 2019 the Bank entered into a new lease in Arlington, WA, that will serve as a new branch location. The Arlington property was purchased through a LLC owned by the Company, and the Bank will lease that property from the LLC. We do not expect this lease to have a financial statement impact on a consolidated basis. As of September 30, 2019, the Company does not have any leases that have not yet commenced. At September 30, 2019, lease expiration dates ranged from two to 26 years, with additional renewal options on certain leases typically ranging from 5 to 10 years. At September 30, 2019, the weighted average remaining lease term for the Company’s operating leases was 9.7 years. Rental expense for operating leases is recognized on a straight-line basis over the lease term and amounted to $1.1 million and $853,000, respectively, for the nine months ended September 30, 2019 and 2018. Variable lease components, such as fair market value adjustments, are expensed as incurred and not included in ROU assets and operating lease liabilities. The following table presents the minimum annual lease payments under the terms of these leases, inclusive of renewal options that the Company is reasonably certain to renew, at September 30, 2019: September 30, (dollars in thousands) 2019 October 1, 2019 to December 31, 2019 $ 325 2020 1,304 2021 1,291 2022 1,296 2023 1,306 2024 and thereafter 4,936 Total lease payments 10,458 Less: amounts representing interest 1,611 Present value of lease liabilities $ 8,847 The following table presents the components of total lease expense and operating cash flows for the nine months ended September 30, 2019: September 30, (dollars in thousands) 2019 Lease expense: Operating lease expense $ 991 Variable lease expense 98 Total lease expense (1) $ 1,089 Cash paid: Cash paid reducing operating lease liabilities $ 1,074 (1) Included in net occupancy expense in the Condensed Consolidated Statements of Income (Unaudited).

Stock-Based Compensation	Note 7 - Stock-Based Compensation Stock Options and Restricted Stock On April 30, 2018, the Company’s shareholders approved the Coastal Financial Corporation 2018 Omnibus Incentive Plan (2018 Plan). The 2018 Plan authorizes the Company to grant awards, including but not limited to, stock options and restricted stock awards, to eligible employees, directors or individuals that provide service to the Company, up to an aggregate of 500,000 shares of common stock. The 2018 Plan replaces both the Company’s 2006 Stock Option and Equity Compensation Plan (2006 Plan) and its Directors’ Stock Bonus Plan. Existing awards will vest under the terms granted and no further awards will be made under the previous plans. Shares available to be granted under the 2018 Plan totaled 361,311 at September 30, 2019. Stock Option Awards In January 2019, the Company granted 26,737 nonqualified stock options under the 2018 Plan to an employee, which vest ratably over 10 years. In January 2019, the Company also granted 99,100 qualified stock options under the 2018 Plan to employees, which vest ratably over 10 years. The fair value of each option award is estimated on the date of grant using the Black-Scholes option pricing model that uses the assumptions noted in the following table. Expected volatilities are based on historical volatility of the Company’s stock and other factors. The Company uses the vesting term and contractual life to determine the expected life. The risk-free interest rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. Compensation expense related to unvested stock option awards is reversed at date of forfeiture. The following assumptions were used to estimate the value of options granted under the 2006 Plan and the 2018 Plan as applicable in the periods indicated: Nine months ended September 30, 2019 Nine months ended September 30, 2018 Expected term 10.0 years 10.0 years Expected stock price volatility 48.79 % 41.89 % Risk-free interest rate 2.74 % 2.66 % Expected dividends Zero Zero Weighted average grant date fair value $ 9.22 $ 3.95 A summary of stock option activity under the 2018 Plan and 2006 Plan during the nine months ended September 30, 2019: Options Shares Weighted- Average Exercise Price Weighted- Average Remaining Contractual Term (Years) Aggregate Intrinsic Value (dollars in thousands, except per share amounts) Outstanding at December 31, 2018 688,310 $ 6.39 6.38 Granted 125,837 14.91 Exercised (17,760 ) 6.15 Forfeited or expired (10,130 ) 8.78 Outstanding at September 30, 2019 786,257 $ 7.72 6.20 $ 5,815 Vested or expected to vest at September 30, 2019 786,257 $ 7.72 6.20 $ 5,815 Exercisable at September 30, 2019 261,232 $ 6.01 4.49 $ 2,376 The total intrinsic value (which is the amount by which the stock price exceeds the exercise price) of options exercised during the three and nine months ended September 30, 2019 was $35,000 and $170,000, respectively and was $106,000 and $173,000 for the three and nine months ended September 30, 2018. As of September 30, 2019, there was $2,422,000 of total unrecognized compensation cost related to nonvested stock options granted under the 2018 Plan and 2006 Plan. Total unrecognized compensation costs are adjusted for unvested forfeitures. The Company expects to recognize that cost over a weighted-average period of approximately 7.7 years. Compensation expense recorded related to stock options was $101,000 and $295,000 for the three and nine months ended September 30, 2019, respectively, and $71,000 and $207,000 for the three and nine months ended September 30, 2018, respectively. Restricted Stock Awards The fair value of restricted stock awards is equal to the fair value of the Company’s stock at the date of grant. Compensation expense is recognized over the vesting period that the awards are based. Restricted stock awards are participating securities. As of September 30, 2019 there was $54,000 of total unrecognized compensation cost related to nonvested restricted stock awards. The Company expects to recognize that cost over the remaining weighted-average vesting period of approximately 7.3 years. Compensation expense recorded related to restricted stock awards was $2,000 and $5,000 for the three and nine months ended September 30, 2019 and was nominal for the three and nine months ended September 30, 2018. A summary of the Company’s nonvested shares at September 30, 2019 and changes during the nine-month period is presented below: Nonvested shares Shares Weighted- Average Grant Date Fair Value Aggregate Intrinsic Value (all amounts in dollars except per share amounts) Nonvested shares at December 31, 2018 5,200 $ 12.32 Granted - - Forfeited (1,200 ) 6.25 Vested - - Nonvested shares at September 30, 2019 4,000 $ 15.35 $ - Director’s Stock Bonus The Company adopted and subsequently amended the Director’s Stock Bonus Plan (Bonus Plan). The Bonus Plan would have expired on May 31, 2018 but was replaced on April 30, 2018, when the shareholders approved the 2018 Plan. Under the Bonus Plan, the Company could grant up to 50,000 shares. Stock was granted to directors who attended at least 75% of the scheduled board meetings during the prior year. Grants cliff vest over two years from date awarded, contingent on the director still being a director of the Company. During the vesting period, the grants are considered participating securities. Grants also immediately vest when a director has attained the retirement age of 72 and retires from the Board. The Bonus Plan granted shares with a total market value of $5,000 per director, per year, with the exception of the board chairman receiving $7,500 per year, and committee chairmen receiving $6,250 per year. The amended Bonus Plan would have expired on May 31, 2018 and it was replaced on April 30, 2018 by the 2018 Plan. Awards previously granted under the Bonus Plan will vest under the term granted. Under the 2018 Plan, eligible directors are granted stock with a total market value of $5,000. Directors unable to receive stock will receive cash in lieu upon completion of the vesting period. Cash awards are recognized over the vesting period and recorded in other liabilities until paid. In January 2019, there were 2,352 shares granted to seven directors at an estimated fair value of $14.91 per share. In January 2018, there were 4,405 shares granted to five directors at an estimated fair value of $7.10 per share. Compensation expense recorded related to the Bonus Plan totaled $8,000 and $25,000 for the three and nine months ended September 30, 2019, respectively, and $8,000 and $23,000 for the three and nine months ended September 30, 2018, respectively.

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (that is, not a forced liquidation or distressed sale). GAAP establishes a consistent framework for measuring fair value and disclosure requirements about fair value measurements. Among other things, the accounting standard requires the reporting entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s estimates for market assumptions. These two types of inputs create the following fair value hierarchy: • Level 1 – Quoted prices in active markets for identical instruments. An active market is a market in which transactions occur with sufficient frequency and volume to provide pricing information on an ongoing basis. A quoted price in an active market provides the most reliable evidence of fair value and shall be used to measure fair value whenever available. • Level 2 – Observable inputs other than Level 1 including quoted prices in active markets for similar instruments, quoted prices in less active markets for identical or similar instruments, or other observable inputs that can be corroborated by observable market data. • Level 3 – Unobservable inputs supported by little or no market activity for financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation; also includes observable inputs from nonbinding single dealer quotes not corroborated by observable market data. The estimated fair value amounts of financial instruments have been determined by the Company using available market information and appropriate valuation methodologies. However, considerable judgment is required to interpret data to develop the estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could realize at a future date. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. In addition, reasonable comparability between financial institutions may not be likely due to the wide range of permitted valuation techniques and numerous estimates that must be made given the absence of active secondary markets for certain financial instruments. This lack of uniform valuation methodologies also introduces a greater degree of subjectivity to these estimated fair values. Items measured at fair value on a recurring basis – The following fair value hierarchy table presents information about the Company’s assets that are measured at fair value on a recurring basis at the dates indicated: Level 1 Level 2 Level 3 Total Fair Value (dollars in thousands) September 30, 2019 Available-for-sale U.S. Treasury securities $ 24,899 $ - $ - $ 24,899 U.S. Government agencies - 2,992 - 2,992 U.S. Agency collateralized mortgage obligations - 138 - 138 U.S. Agency residential mortgage-backed securities - 30 - 30 Municipals - 260 - 260 $ 24,899 $ 3,420 $ - $ 28,319 December 31, 2018 Available-for-sale U.S. Treasury securities $ 33,241 $ - $ - $ 33,241 U.S. Government agencies - 2,957 - 2,957 U.S. Agency collateralized mortgage obligations - 169 - 169 U.S. Agency residential mortgage-backed securities - 38 - 38 Municipals - 255 - 255 $ 33,241 $ 3,419 $ - $ 36,660 The following methods were used to estimate the fair value of the class of financial instruments above: Investment securities - The fair value of securities is based on quoted market prices, pricing models, quoted prices of similar securities, independent pricing sources, and discounted cash flows. Limitations: The fair value estimates presented herein are based on pertinent information available to management as of September 30, 2019 and December 31, 2018. The factors used in the fair values estimates are subject to change subsequent to the dates the fair value estimates are completed, therefore, current estimates of fair value may differ significantly from the amounts presented herein. Assets measured at fair value using significant unobservable inputs (Level 3) The following table provides a description of the valuation technique, unobservable inputs, and qualitative information about the unobservable inputs for the Company’s assets and liabilities classified as Level 3 and measured at fair value on a nonrecurring basis at the dates indicated: Valuation Technique Unobservable Inputs September 30, 2019 Weighted Average Rate December 31, 2018 Weighted Average Rate Impaired loans Collateral valuations Discount to appraised value 10 % 9 % Items measured at fair value on a nonrecurring basis – The following table presents financial assets and liabilities measured at fair value on a nonrecurring basis and the level within the fair value hierarchy of the fair value measurements for those assets at the dates indicated: Level 1 Level 2 Level 3 Total Fair Value (dollars in thousands) September 30, 2019 Impaired loans $ - $ - $ 1,073 $ 1,073 Total $ - $ - $ 1,073 $ 1,073 December 31, 2018 Impaired loans $ - $ - $ 493 $ 493 Total $ - $ - $ 493 $ 493 The amounts disclosed above represent the fair values at the time the nonrecurring fair value measurements were made, and not necessarily the fair value as of the dates reported on. Impaired loans - A loan is considered impaired when it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement. Impairment is measured based on the fair value of the underlying collateral or the discounted cash expected future cash flows. Subsequent changes in the value of impaired loans are included within the provision for loan losses in the same manner in which impairment initially was recognized or as a reduction in the provision that would otherwise be reported. Impaired loans are evaluated quarterly to determine if valuation adjustments should be recorded. The need for valuation adjustments arises when observable market prices or current appraised values of collateral indicate a shortfall in collateral value compared to current carrying values of the related loan. If the Company determines that the value of the impaired loan is less than the carrying value of the loan, the Company either establishes an impairment reserve as a specific component of the allowance for loan losses or charges off the impairment amount. These valuation adjustments are considered nonrecurring fair value adjustments.

The Bank was incorporated and commenced operations in 1997 and is a Washington state-chartered commercial bank and Federal Reserve System (Federal Reserve) state member bank. The Company provides a full range of banking services to small and medium-sized businesses, professionals, and individuals throughout the greater Puget Sound area through its 14 branches in Snohomish, Island, and King Counties, the Internet, and its mobile banking application. The Bank’s main branch and the headquarters of the Bank and Company are located in Everett, Washington. The Bank’s deposits are insured in whole or in part by the FDIC. The Bank’s loans and deposits are primarily within the greater Puget Sound area, and the Bank’s primary funding source is deposits from customers. The Bank is subject to regulation by the Federal Reserve and the Washington State Department of Financial Institutions Division of Banks. The Federal Reserve also has supervisory authority over the Company.
Financial Statement Preparation	Financial statement presentation - The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim reporting requirements and with instructions to Form 10-Q and Article 10 of Regulation S-X, and therefore do not include all the information and notes included in the annual consolidated financial statements in conformity with GAAP. These interim condensed consolidated financial statements and accompanying notes should be read in conjunction with the Company’s audited consolidated financial statements and accompanying notes included in the Company’s Annual report on Form 10-K as filed with the U.S. Securities and Exchange Commission (SEC) on March 28, 2019. Operating results for the three and nine months ended September 30, 2019 are not necessarily indicative of the results that may be expected for future periods. Amounts presented in the consolidated financial statements and footnote tables are rounded and presented in thousands of dollars except per-share amounts, which are presented in dollars. In the narrative footnote discussion, amounts are rounded to thousands and presented in dollars. In management’s opinion, all accounting adjustments necessary to accurately reflect the financial position and results of operations on the accompanying consolidated financial statements have been made. These adjustments include normal and recurring accruals considered necessary for a fair and accurate presentation.
Principles of Consolidation	Principles of consolidation - The consolidated financial statements include the accounts of the Company and the Bank. All significant intercompany accounts have been eliminated in consolidation.
Business Segments	Business Segments - The Company is managed by legal entity and not by lines of business. The entity’s primary business is that of a traditional banking institution, gathering deposits and originating loans for portfolio in its market areas. The Bank offers a wide variety of deposit products to its customers. Lending activities include the origination of real estate, commercial and industrial, and consumer loans. Interest income on loans is the Company’s primary source of revenue, and is supplemented by interest income on deposits with other banks, interest income from investment securities, deposit service charges, and other service provided activities. The Company has determined that its current business and operations consist of a single reporting segment and, therefore, segment disclosures are not required.
Estimates	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 financial statements and the reported amounts of revenues and expenses during the reporting period. Management believes that its critical accounting policies include determining the allowance for loan losses, the fair value of the Company’s investment securities, deferred tax assets, and financial instruments. Actual results could differ significantly from those estimates.
Subsequent Events	Subsequent Events - The Company has evaluated events and transactions subsequent to September 30, 2019 for potential recognition or disclosure.
Accounting Policies	Accounting policies – Our complete accounting policies are described in Note 1, summary of significant accounting policies of the Company’s audited consolidated financial statements as of and for the years ended December 31, 2018 and 2017 included in the Company’s Annual Report Form 10-K filed with the SEC on March 28, 2019.
Reclassifications	Reclassifications - Certain amounts reported in prior quarters' consolidated financial statements have been reclassified to conform to the current presentation with no effect on stockholders’ equity or net income.
Accounting Standards Adopted in 2019	Accounting Standards Adopted in 2019 In February 2016, FASB issued ASU 2016-02, Leases (Topic 842) Our operating leases relate primarily to office space and bank branches.
