Accounting Policies [Abstract]
General	(1) General Prime Meridian Holding Company (“PMHG”) owns 100% of the outstanding common stock of Prime Meridian Bank (the “Bank”) (collectively the “Company”). PMHG’s primary activity is the operation of the Bank. The Bank is a Florida state-chartered commercial bank. The deposit accounts of the Bank are insured up to the applicable limits by the Federal Deposit Insurance Corporation (“FDIC”). The Bank offers a variety of community banking services to individual and corporate clients through its three banking offices located in Tallahassee and Crawfordville, Florida and its online banking platform. In the opinion of management, the accompanying condensed consolidated financial statements of the Company contain all adjustments (consisting principally of normal recurring accruals) necessary to present fairly the financial position at June 30, 2016, and the results of operations for the three and six month periods ended June 30, 2016 and 2015. The results of operations for the three months ended June 30, 2016 and the six months ended June 30, 2016, respectively, are not necessarily indicative of the results to be expected for the full year. Comprehensive Income. Stock-Based Compensation. Mortgage Banking Revenue. Recent Accounting Standards Update. (continued) The ASU requires enhanced disclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s portfolio. These disclosures include qualitative and quantitative requirements that provide additional information about the amounts recorded in the financial statements. Additionally, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The ASU will take effect for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early application will be permitted for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018.

It is expected that the securities would not be settled at a price less than the par value of the investments. Because the decline in fair value is attributable to market conditions and not credit quality, and because the Company has the ability and intent to hold these investments until a market price recovery or maturity, these investments are not considered other-than-temporarily impaired.

All loans are underwritten based upon standards set forth in the policies approved by the Company’s Board of Directors. The Company identifies the portfolio segments and classes as follows: Real Estate Mortgage Loans. Commercial. Residential and Home Equity. Construction. Commercial Loans. Additionally, there may be refinancing risk if a commercial loan includes a balloon payment which must be refinanced or paid off at loan maturity. In reference to our risk management process, our commercial loan portfolio presents a higher risk profile than our consumer real estate and consumer loan portfolios. Therefore, we require that all loans to businesses must have a clearly stated and reasonable payment plan to allow for timely retirement of debt, unless secured by liquid collateral or as otherwise justified. Consumer and Other Loans.

The Company analyzes loans individually by classifying the loans as to credit risk. Loans classified as substandard or special mention are reviewed quarterly by the Company for further deterioration or improvement to determine if they are appropriately classified and whether there is any impairment. All loans are graded upon initial issuance. Furthermore, construction loans, non-owner occupied commercial real estate loans, and commercial loan relationships in excess of $500,000 are reviewed at least annually. The Company determines the appropriate loan grade during the renewal process and reevaluates the loan grade in situations when a loan becomes past due. Loans excluded from the review process above are generally classified as pass credits until: (a) they become past due; (b) management becomes aware of deterioration in the credit worthiness of the borrower; or (c) the client contacts the Company for a modification. In these circumstances, the loan is specifically evaluated for potential classification as to special mention, substandard or even charged-off. The Company uses the following definitions for risk ratings: Pass Special Mention Substandard Doubtful Loss At June 30, 2016, there were three loans on nonaccrual.

Until a bank holding company’s assets reach $1 billion, the risk-based capital and leverage guidelines issued by the Federal Reserve are applied to bank holding companies on a nonconsolidated basis, unless the bank holding company is engaged in nonbank activities involving significant leverage, or it has a significant amount of outstanding debt held by the general public. Instead, a bank holding company with less than $1 billion in assets generally applies the risk-based capital and leverage capital guidelines on a bank-only basis and must only meet a debt-to-equity ratio at the holding company level. The FDIC risk-based capital guidelines apply directly to insured state banks, regardless of whether they are subsidiaries of a bank holding company. Both agencies’ requirements, which are substantially similar, establish minimum capital ratios in relation to assets, both on an aggregate basis as adjusted for credit risks and off-balance sheet exposures. The risk weights assigned to assets are based primarily on credit risks. A particular asset is assigned to a risk category depending upon its severity of risk. Under the guidelines, capital is compared to the relative risk related to the balance sheet. To derive the risk included in the balance sheet, risk weights (from 0% to 1,250%) are applied to different balance sheet and off-balance sheet assets, primarily based on the relative credit risk of the counterparty. The assignment of risk weightings to certain assets are also subject to qualitative judgments by our regulators. Capital is then classified into three categories, Common Equity Tier 1, Additional Tier 1, and Tier 2. Common Equity Tier 1 Capital (“CET1”) is the sum of common stock instruments and related surplus net of treasury stock, retained earnings, and qualifying minority interests, less applicable regulatory adjustments and deductions that include Accumulated Other Comprehensive Income (“AOCI”). Mortgage-servicing assets, deferred tax assets, and investments in financial institutions are limited to an aggregate of 15% of CET1 and 10% of CET1 individually. Additional Tier 1 Capital includes noncumulative perpetual preferred stock, Tier 1 minority interests, grandfathered trust preferred securities, and Troubled Asset Relief Program instruments, less applicable regulatory adjustments and deductions. Tier 2 Capital includes subordinated debt and preferred stock, total capital minority interests not included in Tier 1, and ALLL not exceeding 1.25% percent of risk-weighted assets, less applicable regulatory adjustments and deductions. The Bank is also subject to the Basel III capital level threshold requirements under the FDIC’s Prompt Corrective Action regulations. These regulations are intended to ensure that banks maintain strong capital positions even in the event of severe economic downturns or unforeseen losses. Changes that could affect the Bank going forward include additional constraints on the inclusion of deferred tax assets in capital and increased risk weightings for nonperforming loans and acquisition/development loans in regulatory capital. Under those regulations, the Company elected an irreversible one-time opt-out to exclude AOCI from regulatory capital in the first quarter of 2015. The following is a summary at June 30, 2016 and December 31, 2015 of the regulatory capital requirements to be considered “well-capitalized” and the Bank’s capital position (dollars in thousands). Actual For Capital Adequacy Purposes For Well Capitalized Purposes Amount Percentage Amount Percentage Amount Percentage As of June 30, 2016: Tier 1 Leverage Capital Ratio $ 24,630 9.16 % $ 10,757 4.00 % $ 13,446 5.00 % Common Equity Tier 1 Risk-Based Capital Ratio 24,630 11.70 9,476 4.50 13,687 6.50 Tier 1 Risk-Based Capital Ratio 24,630 11.70 12,634 6.00 16,845 8.00 Total Risk-Based Capital Ratio 27,263 12.95 16,845 8.00 21,057 10.00 As of December 31, 2015: Tier 1 Leverage Capital Ratio $ 23,511 9.48 % $ 9,918 4.00 % $ 12,398 5.00 % Common Equity Tier 1 Risk-Based Capital Ratio 23,511 12.79 8,269 4.50 11,945 6.50 Tier 1 Risk-Based Capital Ratio 23,511 12.79 11,026 6.00 14,701 8.00 Total Risk-Based Capital Ratio 25,810 14.05 14,701 8.00 18,377 10.00 At June 30, 2016, the Bank was well-capitalized with all capital ratios exceeding the well-capitalized requirement.
