Accounting Policies [Abstract]

Basis of Presentation

Basis of presentation

The accompanying condensed consolidated financial statements and notes have been prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP") for interim financial information and do not contain all of the information and footnotes required by U.S. GAAP for complete financial statements. For a more complete description of the Company’s business and accounting policies, these condensed consolidated interim financial statements should be read in conjunction with the audited consolidated financial statements of Kinsale Capital Group, Inc. and its wholly owned subsidiaries (the "Company") included in the Annual Report on Form 10-K for the year ended December 31, 2018. In the opinion of management, all adjustments necessary for a fair presentation of the condensed consolidated financial statements have been included. Such adjustments consist only of normal recurring items. All significant intercompany balances and transactions have been eliminated in consolidation. Interim results are not necessarily indicative of results of operations for the full year.

Use of Estimates

Use of estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Management periodically reviews its estimates and assumptions.

ASU 2016-02, Leases (Topic 842)

In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)" to improve the financial reporting of leasing transactions. Under this ASU, lessees will recognize a right-of-use ("ROU") asset and corresponding liability on the balance sheet for all leases, except for leases covering a period of 12 months or less. The lessee’s income statement treatment for leases will vary depending on the nature and classification of the lease. Effective January 1, 2019, the Company adopted this ASU and recorded a ROU asset and corresponding lease liability of approximately $0.9 million. The ROU and operating lease liability are included in "other assets" and "other liabilities," respectively, in the accompanying consolidated balance sheet.

The Company elected the package of practical expedients permitted under the adoption of the new standard, which allowed the Company to account for existing leases under their current classification, as well as omit any new costs classified as initial direct costs, under the new standard. This election kept the existing agreements as operating leases. The Company also elected the practical expedient allowing an accounting policy election by class of underlying asset, to account for separate lease and nonlease components as a single lease component. In addition, the Company has implemented the necessary internal controls relating to the adoption of the standard.

ASU 2017-08, Premium Amortization on Purchased Callable Debt Securities

In March 2017, the FASB issued ASU 2017-08, "Premium Amortization on Purchased Callable Debt Securities," which shortens the amortization period of the premium for certain callable debt securities, from the contractual maturity date to the earliest call date.

ASU 2016-13, Financial Instruments – Credit Losses (Topic 326)

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments – Credit Losses (Topic 326)" to provide more useful information about the expected credit losses on financial instruments. Current GAAP delays the recognition of credit losses until it is probable a loss has been incurred. The update will require a financial asset measured at amortized cost to be presented at the net amount expected to be collected by means of an allowance for credit losses that runs through net income. Credit losses relating to available-for-sale debt securities will also be recorded through an allowance for credit losses. However, the amendments would limit the amount of the allowance to the amount by which fair value is below amortized cost. The measurement of credit losses on available-for-sale securities is similar under current GAAP, but the update requires the use of the allowance account through which amounts can be reversed, rather than through an irreversible write-down. This ASU is effective for annual and interim reporting periods beginning after December 15, 2019. Early adoption is permitted beginning after December 15, 2018. Upon adoption, the update will be applied using the modified-retrospective approach, by which a cumulative-effect adjustment will be made to retained earnings as of the beginning of the first reporting period presented. The Company is currently evaluating the impact of the adoption on its consolidated financial statements.

There are no other prospective accounting standards which, upon their effective date, would have a material impact on the Company's consolidated financial statements.
