ASU 2016-16 Income Taxes [Member]
Interim Statement Presentation [Line Items]
New Accounting Pronouncement or Change in Accounting Principle, Name	ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other than Inventory
New Accounting Pronouncement or Change in Accounting Principle, Description	provides new guidance regarding when an entity should recognize the income tax consequences of certain intra-entity asset transfers. Prior to the adoption of ASU 2016-16, U.S. GAAP prohibited entities from recognizing the income tax consequences of intercompany asset transfers, including transfers of intellectual property. The seller deferred any net tax effect, and the buyer was prohibited from recognizing a deferred tax asset on the difference between the newly created tax basis of the asset in its tax jurisdiction and its financial statement carrying amount as reported in the consolidated financial statements. ASU 2016-16 requires entities to recognize these tax consequences in the period in which the transfer takes place, with the exception of inventory transfers

ASU 2014-09 will replace most existing revenue recognition guidance in U.S. GAAP. The new standard introduces a five-step process to be followed in determining the amount and timing of revenue recognition. It also provides guidance on accounting for costs incurred to obtain or fulfill contracts with customers, and establishes disclosure requirements which are more extensive than those required under existing U.S. GAAP

Such guidance will impact how premiums are amortized on our available-for-sale investments. ASU 2017-08 is effective for the Company in the first quarter of 2019, with early adoption permitted.
