Accounting Policies [Abstract] | |
Accounting Policies | NOTE 1 — Accounting Policies The condensed consolidated financial statements include the accounts of Cincinnati Financial Corporation and its consolidated subsidiaries, each of which is wholly owned. These statements are presented in conformity with accounting principles generally accepted in the United States of America (GAAP). All intercompany balances and transactions have been eliminated in consolidation. The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect amounts reported in the financial statements and accompanying notes. Our actual results could differ from those estimates. Certain financial information that is normally included in annual financial statements prepared in accordance with GAAP, but that is not required for interim reporting purposes, has been condensed or omitted. Our June 30, 2018 , condensed consolidated financial statements are unaudited. We believe that we have made all adjustments, consisting only of normal recurring accruals, that are necessary for fair presentation. These condensed consolidated financial statements should be read in conjunction with our consolidated financial statements included in our 2017 Annual Report on Form 10-K. The results of operations for interim periods do not necessarily indicate results to be expected for the full year. Adopted Accounting Updates ASU 2014-09 Revenue from Contracts with Customers In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers . ASU 2014-09 requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. Insurance contracts do not fall within the scope of this ASU. The effective date of ASU 2014-09 was for interim and annual reporting periods beginning after December 15, 2017. The company adopted this ASU effective January 1, 2018, and it did not have a material impact on the company's consolidated financial position, cash flows or results of operations. ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10) - Recognition and Measurement of Financial Assets and Financial Liabilities In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10) - Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 revised the accounting related to the classification and measurement of investments in equity securities and the presentation of certain fair value changes for financial liabilities measured at fair value. The effective date of ASU 2016-01 was for interim and annual reporting periods beginning after December 15, 2017. The company adopted this ASU on January 1, 2018, and applied it prospectively without prior period amounts restated. As a result of the adoption, $2.503 billion of after-tax unrealized gains on equity securities was reclassified on January 1, 2018, from accumulated other comprehensive income to retained earnings. Results of operations were impacted as changes in fair value of equity securities are now reported in net income instead of reported in other comprehensive income. As a result of the adoption of this ASU, for the three and six months ended June 30, 2018, net investment gains of $105 million and net investment losses of $86 million in the condensed consolidated statements of income included an increase of $101 million and a decrease of $97 million from the fair value change of equity securities, respectively. ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments . ASU 2016-15 addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The effective date of ASU 2016-15 is for interim and annual reporting periods beginning after December 15, 2017. The company adopted this ASU effective January 1, 2018, and it did not have a material impact on our company's consolidated financial position, cash flows or results of operations. ASU 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost In March 2017, the FASB issued ASU 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Postretirement Benefit Costs . ASU 2017-07 provides guidance on how to present the components of net periodic benefit costs in the income statement for pension plans and other post-retirement benefit plans and allows only the service cost component of net benefit cost to be eligible for capitalization when applicable. The effective date of ASU 2017-07 is for interim and annual reporting periods beginning after December 15, 2017. The company adopted this ASU effective January 1, 2018, and disclosed the line items used in the statements of income to present the service and non-service components of net periodic benefit costs in Note 11, Employee Retirement Benefits, to these consolidated financial statements. The adoption did not have a material impact on our company's consolidated financial position, cash flows or results of operations. ASU 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting. ASU 2017-09 clarifies when to account for a change to the terms or conditions of a share based payment award as a modification. Under the new guidance, modification accounting is required only if the fair value, the vesting conditions, or the classification of the award (as equity or liability) changes as a result of the change in terms or conditions. The effective date of ASU 2017-09 was for interim and annual reporting periods, beginning after December 15, 2017, and was applied prospectively. The company adopted this ASU effective January 1, 2018, and it did not have a material impact on our company's consolidated financial position, cash flows or results of operations. Pending Accounting Updates ASU 2016-02, Leases (Topic 842) In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The main provision of ASU 2016-02 requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous GAAP. The effective date of ASU 2016-02 is for interim and annual reporting periods beginning after December 15, 2018. The ASU has not yet been adopted; however, it is not expected to have a material impact on our company’s consolidated financial position, cash flows or results of operations. ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . ASU 2016-13 amends previous guidance on the impairment of financial instruments by adding an impairment model that allows an entity to recognize expected credit losses as an allowance rather than impairing as they are incurred. The new guidance is intended to reduce complexity of credit impairment models and result in a more timely recognition of expected credit losses. The effective date of ASU 2016-13 is for interim and annual reporting periods beginning after December 15, 2019. The ASU has not yet been adopted. Management is currently evaluating the impact on our company's consolidated financial position, cash flows or results of operations. ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities In March 2017, the FASB issued ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. ASU 2017-08 amends guidance on the amortization period of premiums on certain purchased callable debt securities. The amendments shorten the amortization period of premiums on certain purchased callable debt securities to the earliest call date. The amendments should be applied on a modified retrospective basis through a cumulative-effect adjustment to beginning retained earnings. The effective date of ASU 2017-08 is for interim and annual reporting periods beginning after December 15, 2018. The ASU has not yet been adopted; however, it is not expected to have a material impact on our company's consolidated financial position, cash flows or results of operations. ASU 2018-07, Compensation - Stock Compensation (Topic 718) - Improvements to Nonemployee Share-Based Payment Accounting In June 2018, the FASB issued ASU 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting . ASU 2018-07 expands the scope of Topic 718, Compensation - Stock Compensation, which currently only includes share-based payments issued to employees, to include share-based payments issued to nonemployees for the acquisition of goods and services. The effective date of ASU 2018-07 is for interim and annual reporting periods beginning after December 15, 2018. The ASU has not yet been adopted; however, it is not expected to have a material impact on our company's consolidated financial position, cash flows or results of operations. |

Investments [Abstract] | |
Investments | Investments On January 1, 2018, we adopted ASU 2016-01, which resulted in changes in the fair value of equity securities still held, being reported in net income instead of being reported in other comprehensive income. See Note 1, Accounting Policies, for additional discussion. The following table provides cost or amortized cost, gross unrealized gains, gross unrealized losses and fair value for our fixed-maturity and equity securities: (Dollars in millions) Cost or amortized cost Gross unrealized Fair value At June 30, 2018 gains losses Fixed maturity securities: Corporate $ 5,625 $ 110 $ 57 $ 5,678 States, municipalities and political subdivisions 4,316 78 36 4,358 Commercial mortgage-backed 283 2 4 281 Government-sponsored enterprises 277 — 8 269 United States government 41 — 1 40 Foreign government 10 — — 10 Total $ 10,552 $ 190 $ 106 $ 10,636 At December 31, 2017 Fixed maturity securities: Corporate $ 5,420 $ 246 $ 13 $ 5,653 States, municipalities and political subdivisions 4,316 155 6 4,465 Commercial mortgage-backed 280 7 1 286 Government-sponsored enterprises 257 1 4 254 United States government 31 — — 31 Foreign government 10 — — 10 Subtotal 10,314 409 24 10,699 Equity securities: Common equities 2,918 3,135 14 6,039 Nonredeemable preferred equities 176 34 — 210 Subtotal 3,094 3,169 14 6,249 Total $ 13,408 $ 3,578 $ 38 $ 16,948 The net unrealized investment gains in our fixed-maturity portfolio at June 30, 2018 , are primarily the result of the continued low interest rate environment that increased the fair value of our fixed-maturity portfolio. Our commercial mortgage-backed securities had an average rating of Aa1/AA at June 30, 2018 , and December 31, 2017 . At June 30, 2018 , Apple Inc.

Fair Value Disclosures [Abstract] | |
Fair Value Measurements | Fair Value Measurements In accordance with accounting guidance for fair value measurements and disclosures, we categorized our financial instruments, based on the priority of the observable and market-based data for the valuation technique used, into a three-level fair value hierarchy. The fair value hierarchy gives the highest priority to quoted prices with readily available independent data in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable market inputs (Level 3). When various inputs for measurement fall within different levels of the fair value hierarchy, the lowest observable input that has a significant impact on fair value measurement is used. Our valuation techniques have not changed from those used at December 31, 2017 , and ultimately management determines fair value. See our 2017 Annual Report on Form 10-K, Item 8, Note 3, Fair Value Measurements, Page 132, for information on characteristics and valuation techniques used in determining fair value. Fair Value Disclosures for Assets The following tables illustrate the fair value hierarchy for those assets measured at fair value on a recurring basis at June 30, 2018 , and December 31, 2017 . We do not have any liabilities carried at fair value. There were no transfers between Level 1 and Level 2.

Total Level 3 assets continue to be less than 1 percent of financial assets measured at fair value in the condensed consolidated balance sheets. Assets presented in the table below were valued based primarily on broker/dealer quotes for which there is a lack of transparency as to inputs used to develop the valuations. Transfers out of Level 3 included situations where a broker quote was used without observable inputs or data that could be corroborated by our pricing vendors in the prior period and significant other observable inputs were identified in the current period. The quantitative detail of these unobservable inputs is neither provided nor reasonably available to us.

The actuarial estimate is subject to review and adjustment by an inter-departmental committee that includes actuarial, claims, underwriting, loss prevention and accounting management. This committee is familiar with relevant company and industry business, claims and underwriting trends, as well as general economic and legal trends that could affect future loss and loss expense payments. The amount we will actually have to pay for claims can be highly uncertain. This uncertainty, together with the size of our reserves, makes the loss and loss expense reserves our most significant estimate. The reserve for loss and loss expenses in the condensed consolidated balance sheets also included $45 million at June 30, 2018 , and $68 million at June 30, 2017 , for certain life and health loss and loss expense reserves. For the three months ended June 30, 2018 , we experienced $31 million of favorable development on prior accident years, including $42 million of favorable development in commercial lines, $17 million of unfavorable development in personal lines, $4 million of favorable development in excess and surplus lines and $2 million of favorable development in our reinsurance assumed operations. Within commercial lines, we recognized favorable reserve development of $18 million for the workers' compensation line, $14 million for the commercial casualty line, $7 million for the commercial property line and $8 million for the other commercial lines due to reduced uncertainty of prior accident year loss and loss adjustment expense for these lines. This was partially offset by unfavorable reserve development of $5 million for the commercial auto line. Within personal lines, we recognized unfavorable reserve development of $14 million for the homeowner line of business due primarily to higher-than-anticipated loss emergence on known claims. For the six months ended June 30, 2018 , we experienced $79 million of favorable development on prior accident years, including $77 million of favorable development in commercial lines, $16 million of unfavorable development in personal lines, $14 million of favorable development in excess and surplus lines and $4 million of favorable development in our reinsurance assumed operations. This included $7 million from favorable development of catastrophe losses. Within commercial lines, we recognized favorable reserve development of $31 million for the workers' compensation line, $28 million for the commercial property line, $10 million for the commercial casualty line and $12 million for the other commercial lines due to reduced uncertainty of prior accident year loss and loss adjustment expense for these lines. This was partially offset by unfavorable reserve development of $4 million for the commercial auto line. Within personal lines, we recognized unfavorable reserve development of $17 million for the homeowner line of business due primarily to higher-than-anticipated loss emergence on known claims. For the three months ended June 30, 2017, we experienced $38 million of favorable development on prior accident years, including $26 million of favorable development in commercial lines, $3 million of favorable development in personal lines and $9 million of favorable development in excess and surplus lines. This included $3 million from favorable development of catastrophe losses. Within commercial lines, we recognized favorable reserve development of $12 million for the workers' compensation line, $7 million for the commercial casualty line, $5 million for the commercial property line and $11 million for the other commercial lines due to reduced uncertainty of prior accident year loss and loss adjustment expense for these lines. This was partially offset by unfavorable reserve development of $9 million for the commercial auto line. For the six months ended June 30, 2017 , we experienced $76 million of favorable development on prior accident years, including $37 million of favorable development in commercial lines, $13 million of favorable development in personal lines, $22 million of favorable development in excess and surplus lines and $4 million of favorable development in our reinsurance assumed operations. This included $14 million from favorable development of catastrophe losses. Within commercial lines, we recognized favorable reserve development of $31 million for the workers' compensation line, $15 million for the commercial property line and $19 million for the other commercial lines due to reduced uncertainty of prior accident year loss and loss adjustment expenses for these lines. This was partially offset by unfavorable reserve development of $20 million for the commercial auto line and $8 million for the commercial casualty line. Commercial auto developed unfavorably due to higher loss cost effects in recent accident years, resulting in an increase of our reserve estimate for claims that have not yet been settled. The unfavorable reserve development for commercial casualty reflected higher than usual large loss activity. |

Liability for Future Policy Benefits [Abstract] | |
Life Policy And Investment Contract Reserves | Life Policy and Investment Contract Reserves We establish the reserves for traditional life insurance policies based on expected expenses, mortality, morbidity, withdrawal rates, timing of claim presentation and investment yields, including a provision for uncertainty. Once these assumptions are established, they generally are maintained throughout the lives of the contracts. We use both our own experience and industry experience, adjusted for historical trends, in arriving at our assumptions for expected mortality, morbidity and withdrawal rates as well as for expected expenses. We base our assumptions for expected investment income on our own experience adjusted for current economic conditions. We establish reserves for the company’s deferred annuity, universal life and structured settlement policies equal to the cumulative account balances, which include premium deposits plus credited interest less charges and withdrawals. Some of our universal life policies contain no-lapse guarantee provisions. For these policies, we establish a reserve in addition to the account balance, based on expected no-lapse guarantee benefits and expected policy assessments.

Reinsurance Disclosures [Abstract] | |
Reinsurance | Reinsurance Primary components of our property casualty reinsurance assumed operations include involuntary and voluntary assumed risks as well as contracts from our reinsurance assumed operations, known as Cincinnati Re. Primary components of our ceded reinsurance include a property per risk treaty, property excess treaty, casualty per occurrence treaty, casualty excess treaty, property catastrophe treaty and catastrophe bonds and retrocessions on our reinsurance assumed operations. Management's decisions about the appropriate level of risk retention are affected by various factors, including changes in our underwriting practices, capacity to retain risks and reinsurance market conditions.

See our 2017 Annual Report on Form 10-K, Item 8, Note 11, Income Taxes, Page 153, which discusses enactment of the Tax Cuts and Jobs Act (the “Tax Act”) on December 22, 2017, and its impact on our financial results for that period. Interpretive guidance of the Tax Act will be received throughout 2018, and we expect to update our estimates and our disclosure on a quarterly basis as interpretative guidance is received within each quarter that it is received. During the period ended June 30, 2018, the U.S. Treasury Department and the Internal Revenue Service have not issued further clarification or guidance for the items for which our accounting for the Tax Act is incomplete. We expect to complete determination of the effects of the Tax Act on our deferred tax assets and liabilities as part of the annual income tax return filing process. As of June 30, 2018 , we had no operating or capital loss carryforwards. |

The above table shows the number of anti-dilutive share-based awards for the three and six months ended June 30, 2018 and 2017 . These share-based awards were not included in the computation of net income per common share (diluted) because their exercise would have anti-dilutive effects. |

Commitments and Contingencies Disclosure [Abstract] | |
Commitments And Contingent Liabilities | Commitments and Contingent Liabilities In the ordinary course of conducting business, the company and its subsidiaries are named as defendants in various legal proceedings. Most of these proceedings are claims litigation involving the company's insurance subsidiaries in which the company is either defending or providing indemnity for third-party claims brought against insureds or litigating first-party coverage claims. The company accounts for such activity through the establishment of unpaid loss and loss expense reserves. We believe that the ultimate liability, if any, with respect to such ordinary-course claims litigation, after consideration of provisions made for potential losses and costs of defense, is immaterial to our consolidated financial condition, results of operations and cash flows. The company and its subsidiaries also are occasionally involved in other legal and regulatory proceedings, some of which assert claims for substantial amounts. These actions include, among others, putative class actions seeking certification of a state or national class. Such proceedings have alleged, for example, breach of an alleged duty to search national databases to ascertain unreported deaths of insureds under life insurance policies. The company's insurance subsidiaries also are occasionally parties to individual actions in which extra-contractual damages, punitive damages or penalties are sought, such as claims alleging bad faith handling of insurance claims or writing unauthorized coverage or claims alleging discrimination by former or current associates. On a quarterly basis, we review these outstanding matters. Under current accounting guidance, we establish accruals when it is probable that a loss has been incurred and we can reasonably estimate its potential exposure. The company accounts for such probable and estimable losses, if any, through the establishment of legal expense reserves. Based on our quarterly review, we believe that our accruals for probable and estimable losses are reasonable and that the amounts accrued do not have a material effect on our consolidated financial condition or results of operations. However, if any one or more of these matters results in a judgment against us or settlement for an amount that is significantly greater than the amount accrued, the resulting liability could have a material effect on the company's consolidated results of operations or cash flows. Based on our most recent review, our estimate for any other matters for which the risk of loss is not probable, but more than remote, is immaterial. |

Adopted Accounting Updates and Pending Accounting Updates | Adopted Accounting Updates ASU 2014-09 Revenue from Contracts with Customers In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers . ASU 2014-09 requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. Insurance contracts do not fall within the scope of this ASU. The effective date of ASU 2014-09 was for interim and annual reporting periods beginning after December 15, 2017. The company adopted this ASU effective January 1, 2018, and it did not have a material impact on the company's consolidated financial position, cash flows or results of operations. ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10) - Recognition and Measurement of Financial Assets and Financial Liabilities In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10) - Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 revised the accounting related to the classification and measurement of investments in equity securities and the presentation of certain fair value changes for financial liabilities measured at fair value. The effective date of ASU 2016-01 was for interim and annual reporting periods beginning after December 15, 2017. The company adopted this ASU on January 1, 2018, and applied it prospectively without prior period amounts restated. As a result of the adoption, $2.503 billion of after-tax unrealized gains on equity securities was reclassified on January 1, 2018, from accumulated other comprehensive income to retained earnings. Results of operations were impacted as changes in fair value of equity securities are now reported in net income instead of reported in other comprehensive income. As a result of the adoption of this ASU, for the three and six months ended June 30, 2018, net investment gains of $105 million and net investment losses of $86 million in the condensed consolidated statements of income included an increase of $101 million and a decrease of $97 million from the fair value change of equity securities, respectively. ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments . ASU 2016-15 addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The effective date of ASU 2016-15 is for interim and annual reporting periods beginning after December 15, 2017. The company adopted this ASU effective January 1, 2018, and it did not have a material impact on our company's consolidated financial position, cash flows or results of operations. ASU 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost In March 2017, the FASB issued ASU 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Postretirement Benefit Costs . ASU 2017-07 provides guidance on how to present the components of net periodic benefit costs in the income statement for pension plans and other post-retirement benefit plans and allows only the service cost component of net benefit cost to be eligible for capitalization when applicable. The effective date of ASU 2017-07 is for interim and annual reporting periods beginning after December 15, 2017. The company adopted this ASU effective January 1, 2018, and disclosed the line items used in the statements of income to present the service and non-service components of net periodic benefit costs in Note 11, Employee Retirement Benefits, to these consolidated financial statements. The adoption did not have a material impact on our company's consolidated financial position, cash flows or results of operations. ASU 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting. ASU 2017-09 clarifies when to account for a change to the terms or conditions of a share based payment award as a modification. Under the new guidance, modification accounting is required only if the fair value, the vesting conditions, or the classification of the award (as equity or liability) changes as a result of the change in terms or conditions. The effective date of ASU 2017-09 was for interim and annual reporting periods, beginning after December 15, 2017, and was applied prospectively. The company adopted this ASU effective January 1, 2018, and it did not have a material impact on our company's consolidated financial position, cash flows or results of operations. Pending Accounting Updates ASU 2016-02, Leases (Topic 842) In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The main provision of ASU 2016-02 requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous GAAP. The effective date of ASU 2016-02 is for interim and annual reporting periods beginning after December 15, 2018. The ASU has not yet been adopted; however, it is not expected to have a material impact on our company’s consolidated financial position, cash flows or results of operations. ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . ASU 2016-13 amends previous guidance on the impairment of financial instruments by adding an impairment model that allows an entity to recognize expected credit losses as an allowance rather than impairing as they are incurred. The new guidance is intended to reduce complexity of credit impairment models and result in a more timely recognition of expected credit losses. The effective date of ASU 2016-13 is for interim and annual reporting periods beginning after December 15, 2019. The ASU has not yet been adopted. Management is currently evaluating the impact on our company's consolidated financial position, cash flows or results of operations. ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities In March 2017, the FASB issued ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. ASU 2017-08 amends guidance on the amortization period of premiums on certain purchased callable debt securities. The amendments shorten the amortization period of premiums on certain purchased callable debt securities to the earliest call date. The amendments should be applied on a modified retrospective basis through a cumulative-effect adjustment to beginning retained earnings. The effective date of ASU 2017-08 is for interim and annual reporting periods beginning after December 15, 2018. The ASU has not yet been adopted; however, it is not expected to have a material impact on our company's consolidated financial position, cash flows or results of operations. ASU 2018-07, Compensation - Stock Compensation (Topic 718) - Improvements to Nonemployee Share-Based Payment Accounting In June 2018, the FASB issued ASU 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting . ASU 2018-07 expands the scope of Topic 718, Compensation - Stock Compensation, which currently only includes share-based payments issued to employees, to include share-based payments issued to nonemployees for the acquisition of goods and services. The effective date of ASU 2018-07 is for interim and annual reporting periods beginning after December 15, 2018. The ASU has not yet been adopted; however, it is not expected to have a material impact on our company's consolidated financial position, cash flows or results of operations. |
