The accompanying unaudited Condensed Consolidated Financial Statements include the accounts of ProAssurance Corporation and its consolidated subsidiaries (ProAssurance, PRA or the Company). The financial statements have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation, consisting of normal recurring adjustments, have been included. ProAssurance’s results for the six months ended June 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019. The accompanying Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and Notes contained in ProAssurance’s December 31, 2018 report on Form 10-K. In connection with its preparation of the Condensed Consolidated Financial Statements, ProAssurance evaluated events that occurred subsequent to June 30, 2019 for recognition or disclosure in its financial statements and notes to financial statements.

Beginning in the third quarter of 2018, ProAssurance operates in five reportable segments as follows: Specialty P&C, Workers' Compensation Insurance, Segregated Portfolio Cell Reinsurance, Lloyd's Syndicates and Corporate. For more information on the Company's segment reporting, including the nature of products and services provided and financial information by segment, refer to Note 14.

ProAssurance is involved in a number of leases, primarily for office facilities. The Company determines if an arrangement is a lease at the inception date of the contract and classifies all leases as either financing or operating. Operating leases are included in operating lease ROU assets and operating lease liabilities on the Condensed Consolidated Balance Sheet as of June 30, 2019. The ROU asset represents the right to use the underlying asset for the lease term. As of June 30, 2019, ProAssurance has no leases that are classified as financing leases.

Operating ROU assets and operating lease liabilities are initially recognized as of the lease commencement date based on the present value of the remaining lease payments, discounted over the term of the lease using a discount rate determined based on information available as of the commencement date. As the majority of ProAssurance's lessors do not provide an implicit discount rate, the Company uses its collateralized incremental borrowing rate in determining the present value of remaining lease payments. Due to the adoption of ASU 2016-02 (see further discussion that follows), the Company used its collateralized incremental borrowing rate as of January 1, 2019 for operating leases that commenced prior to that date. Subsequent to the initial recognition, the operating ROU asset is amortized over the lease term on a straight-line basis as operating lease expense which is included as a component of operating expense on the Condensed Consolidated Statements of Income and Comprehensive Income for the three and six months ended June 30, 2019 and 2018. Leases with an initial term of twelve months or less are considered short-term and are not recorded on the Condensed Consolidated Balance Sheet; lease expense for these leases is also recognized on a straight-line basis over the lease term. Additionally, for leases entered into or reassessed after the adoption of ASU 2016-02, ProAssurance accounts for lease and non-lease components of a contract as a single lease component.

Operating lease ROU assets are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. The carrying amount of a ROU asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use of the underlying leased asset over the remaining lease term. That assessment is based on the carrying amount of the ROU asset at the date it is tested for recoverability and an impairment loss is measured and recognized as the amount by which the carrying amount of the ROU asset exceeds its fair value.

Effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years, the FASB issued guidance that requires a lessee to recognize for all leases (with the exception of short-term leases) a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis, and a right-of-use asset, which is an asset that represents the lessee's right to use, or control the use of, a specified asset for the lease term. ProAssurance adopted the guidance as of January 1, 2019 using a modified retrospective application and elected the transition option provided that allows companies to continue to apply legacy GAAP in comparative periods. Also, ProAssurance elected the package of practical expedients permitted under the guidance, which allowed the Company to carryforward its historical lease classification, its assessment on whether a contract is or contains a lease and its initial direct costs for any leases that existed prior to adoption of the new standard. Furthermore, ProAssurance elected to combine lease and non-lease components and to keep leases with an initial term of 12 months or less off the Condensed Consolidated Balance Sheet and recognize the associated lease payments in the Condensed Consolidated Statements of Income and Comprehensive Income on a straight-line basis over the lease term. ProAssurance recognized total ROU assets and total lease liabilities of approximately $19 million on the Condensed Consolidated Balance Sheet as of January 1, 2019 which relate to ProAssurance's real estate operating leases; the Company does not consider these leases to be material to its financial position. Adoption of this guidance had no material impact on ProAssurance's results of operation or cash flows.

ProAssurance's Revolving Credit Agreement contains a financial covenant regarding permitted leverage ratios based upon Consolidated Funded Indebtedness to Consolidated Total Capitalization; however, adoption of this guidance had no material impact on this covenant. ProAssurance’s Mortgage Loans also contain a financial covenant regarding permitted leverage ratios, principally based upon SAP Consolidated Net Worth; however, as the NAIC did not adopt the principles found in ASU 2016-02, adoption of the guidance had no impact on this covenant.

Effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years, the FASB issued guidance that will require the premium for certain callable debt securities to be amortized over a shorter period than is currently required. Currently amortization is permitted over the contractual life of the instrument and the guidance shortens the amortization to the earliest call date. The purpose of the guidance is to more closely align the amortization period of premiums to expectations incorporated in market pricing on the underlying securities. ProAssurance adopted the guidance as of January 1, 2019. As ProAssurance amortizes premium on callable debt securities to the earliest call date, adoption of the guidance had no material effect on ProAssurance’s results of operations, financial position or cash flows.

Effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years, the FASB issued guidance to improve financial reporting of hedging relationships to better portray the entity's risk management activities in the consolidated financial statements. The new guidance eliminates the requirement to separately measure and report hedge ineffectiveness and requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. ProAssurance adopted the guidance as of January 1, 2019. ProAssurance's derivative instrument at June 30, 2019 is not designated as a hedging instrument; therefore, adoption had no effect on ProAssurance's results of operations, financial position or cash flows.

Effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years, the FASB issued guidance which reduces the complexity in accounting for nonemployee share-based payment awards. The new guidance substantially aligns the accounting for nonemployee share-based payment awards with the accounting guidance for employee share-based payment awards with certain exceptions, including the inputs used in estimating the fair value of the nonemployee awards and the period of time and pattern of expense recognition. ProAssurance adopted the guidance as of January 1, 2019 using a modified retrospective application and recorded a cumulative-effect adjustment of approximately $0.4 million to beginning retained earnings in the Condensed Consolidated Statement of Changes in Capital for the six months ended June 30, 2019. Adoption had no material effect of ProAssurance's results of operations or cash flows.

Effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years, the FASB issued new guidance that permits the use of the Overnight Index Swap Rate based on the Secured Financing Rate as a U.S. benchmark interest rate for hedge accounting purposes. ProAssurance adopted the guidance as of January 1, 2019. As of June 30, 2019, ProAssurance's derivative instrument is not designated as a hedging instrument; therefore, adoption had no effect on ProAssurance's results of operations, financial position or cash flows.

Effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years, the FASB issued guidance that replaces the incurred loss impairment methodology, which delays recognition of credit losses until a probable loss has been incurred, with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. Under the new guidance, credit losses are required to be recorded through an allowance for credit losses account and the income statement will reflect the initial recognition of lifetime expected credit losses for any newly recognized financial assets as well as increases or decreases of expected credit losses that have taken place during the period. Credit losses on available-for-sale fixed maturity securities will be required to be presented as an allowance, rather than as a write-down of the asset, limited to the amount by which the fair value is below amortized cost. Adoption of this guidance is not expected to have a material impact on ProAssurance's available-for-sale fixed maturity portfolio. In addition, ProAssurance's premiums receivable and receivables from reinsurers are also included in the scope of this new guidance; however, ProAssurance has not historically experienced material credit losses due to the financial condition of an insured or reinsurer. ProAssurance plans to adopt the guidance beginning January 1, 2020 and is in the process of evaluating the effect the new guidance would have on its results of operations and financial position.

Effective for the fiscal years beginning after December 15, 2019 and interim periods within those fiscal years, the FASB issued guidance that simplifies the requirements to test goodwill for impairment for business entities that have goodwill reported in their financial statements. The guidance eliminates the second step of the impairment test which measures a goodwill impairment loss by comparing the implied fair value of a reporting unit's goodwill with the carrying amount. In addition, the guidance also eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment. ProAssurance plans to adopt the guidance beginning January 1, 2020. Adoption is not expected to have a material effect on ProAssurance’s results of operations, financial position or cash flows.

Effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years, the FASB issued guidance that eliminates, modifies and adds certain disclosure requirements related to fair value measurements. The new guidance eliminates the requirements to disclose the transfers between Level 1 and Level 2 of the fair value hierarchy, the policy for the timing of transfers between levels of the fair value hierarchy and the valuation process for Level 3 fair value measurements while it modifies existing disclosure requirements related to measurement uncertainty and the requirement to disclose the timing of liquidation of an investee's assets for investments in certain entities that calculate NAV. The new guidance also adds requirements to disclose changes in unrealized gains and losses included in OCI for recurring Level 3 fair value measurements as well as the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. An entity is permitted to early adopt any eliminated or modified disclosure requirements and delay adoption of the additional disclosure requirements until the guidance is effective. During the third quarter of 2018, ProAssurance elected to early adopt the provisions that eliminate and modify certain disclosure requirements within Note 2 on a retrospective basis and adoption of these certain provisions had no material effect on ProAssurance’s results of operations, financial position or cash flows as it affected disclosures only. ProAssurance plans to adopt the additional disclosure requirements beginning January 1, 2020 and adoption is not expected to have a material effect on ProAssurance’s results of operations, financial position or cash flows.

Effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years, the FASB amended the new standard regarding accounting for implementation costs in cloud computing arrangements. The amended guidance substantially aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. ProAssurance plans to adopt the guidance beginning January 1, 2020. Adoption is not expected to have a material effect on ProAssurance’s results of operations, financial position or cash flows.

Effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years, the FASB amended guidance which improves the consistency of the application of the VIE guidance for common control arrangements. The amended guidance requires an entity to consider indirect interests held through related parties under common control on a proportional basis rather than as the equivalent of a direct interest in its entirety when determining whether a decision-making fee is a variable interest. ProAssurance plans to adopt the guidance beginning January 1, 2020. As of June 30, 2019 ProAssurance does not have any material indirect interests held through related parties under common control; therefore, adoption is not expected to have a material effect on ProAssurance’s results of operations, financial position or cash flows.

Effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years, the FASB issued new guidance which clarifies how to assess whether certain transactions between participants in a collaborative arrangement should be accounted for under the revenue from contracts with customers accounting standard when the counterpart is a customer. In addition, the guidance precludes an entity from presenting consideration from a transaction in a collaborative arrangement as revenue from contracts with customers if the counterparty is not a customer for that transaction. ProAssurance plans to adopt the guidance beginning January 1, 2020 and adoption is not expected to have a material effect on ProAssurance’s results of operations, financial position or cash flows.
