STATUTORY ACCOUNTING AND DIVIDEND RESTRICTIONS | STATUTORY ACCOUNTING AND DIVIDEND RESTRICTIONS The Company's insurance subsidiaries are required to report their results of operations and financial position to insurance regulatory authorities on the basis of statutory accounting practices prescribed or permitted by such authorities. Statutory accounting practices primarily differ from U.S. GAAP by charging policy acquisition costs to expense as incurred, establishing future policy benefit liabilities using different actuarial assumptions as well as valuing investments and certain assets and accounting for deferred taxes on a different basis. Aflac reports statutory financial statements that are prepared on the basis of accounting practices prescribed or permitted by the Nebraska Department of Insurance (NDOI). The NDOI recognizes statutory accounting principles and practices prescribed or permitted by the state of Nebraska for determining and reporting the financial condition and results of operations of an insurance company, and for determining a company's solvency under Nebraska insurance law. Statutory Accounting Principles (SAP) as detailed by the National Association of Insurance Commissioners' (NAIC) Accounting Practices and Procedures Manual has been adopted by the state of Nebraska as a component of those prescribed or permitted practices. Additionally, the Director of the NDOI has the right to permit other specific practices which deviate from prescribed practices. Prior to the Japan branch conversion on April 1, 2018, Aflac had been given explicit permission by the Director of the NDOI for two such permitted practices. On April 1, 2018, the Company entered into a series of transactions in order to complete the conversion of the Japan branch into a Japanese insurance corporation. As a result of the conversion, the permitted practices were no longer necessary, therefore they were canceled by the NDOI effective April 2, 2018. Aflac had no permitted practices as of December 31, 2019 and 2018. Aflac's capital and surplus as determined by NAIC basis and Nebraska state basis was $2.1 billion and $2.6 billion as of December 31, 2019 and 2018, respectively. As of December 31, 2019, Aflac's capital and surplus significantly exceeded the required company action level capital and surplus of $.4 billion. As determined on a U.S. statutory accounting basis, Aflac's net income was $864 million in 2019, $1.3 billion in 2018 and $2.6 billion in 2017. Aflac Japan must report its results of operations and financial position to the Japanese Financial Services Agency (FSA) on a Japanese regulatory accounting basis as prescribed by the FSA. Capital and surplus of Aflac Japan, based on Japanese regulatory accounting practices, was $7.8 billion at December 31, 2019, compared with $6.4 billion at December 31, 2018. Japanese regulatory accounting practices differ in many respects from U.S. GAAP. Under Japanese regulatory accounting practices, policy acquisition costs are expensed immediately; policy benefit and claim reserving methods and assumptions are different; premium income is recognized on a cash basis; different consolidation criteria apply to VIEs; reinsurance is recognized on a different basis; and investments can have a separate accounting classification and treatment referred to as policy reserve matching bonds (PRM). The Parent Company depends on its subsidiaries for cash flow, primarily in the form of dividends and management fees. Consolidated retained earnings in the accompanying financial statements largely represent the undistributed earnings of the Company's insurance subsidiary. Amounts available for dividends, management fees and other payments to the Parent Company by its insurance subsidiaries may fluctuate due to different accounting methods required by regulatory authorities. These payments are also subject to various regulatory restrictions and approvals related to safeguarding the interests of insurance policyholders. Aflac must maintain adequate RBC for U.S. regulatory authorities, and Aflac Japan must maintain adequate solvency margins for Japanese regulatory authorities. The maximum amount of dividends that can be paid to the Parent Company by Aflac and CAIC without prior approval of Nebraska's director of insurance is the greater of the net income from operations, which excludes net realized investment gains, for the previous year determined under statutory accounting principles, or 10% of statutory capital and surplus as of the previous year-end. Dividends declared by Aflac during 2020 in excess of $864 million would require such approval. Aflac declared dividends of $1.3 billion during 2019. After the Japan branch conversion as of April 1, 2018, Aflac Japan is required to meet certain financial criteria as governed by Japanese corporate law in order to provide dividends to the Parent Company. Under these criteria, dividend capacity at Aflac Japan is basically defined as retained earnings excluding capital reserves, which represent equity generated by capital profits that are statutorily required in Japan, less net after-tax unrealized losses on available-for-sale securities based on the previous fiscal year-end. Prior to April 1, 2018, a portion of Aflac Japan earnings, as determined on a Japanese regulatory accounting basis, could be remitted each year to Aflac U.S. after complying with solvency margin provisions and satisfying various conditions imposed by Japanese regulatory authorities for protecting policyholders. Profit remittances to the U.S. could fluctuate due to changes in the amounts of Japanese regulatory earnings. Among other items, factors affecting regulatory earnings include Japanese regulatory accounting practices and fluctuations in currency translation of Aflac Japan's U.S. dollar-denominated investments and related investment income into yen. Profits remitted by Aflac Japan to the Parent Company, after April 1, 2018, and to Aflac U.S., prior to April 1, 2018, were as follows for the years ended December 31:
| In Dollars |  | In Yen
(In millions of dollars and billions of yen) | 2019 |  | 2018 |  | 2017 |  | 2019 |  | 2018 |  | 2017
Profit remittances |  | $ | 2,070 |  |  |  |  | $ | 808 |  |  |  |  | $ | 1,150 |  |  |  |  | ¥ | 225.2 |  |  |  |  | ¥ | 89.7 |  |  |  |  | ¥ | 129.3 |  |
