| Revenue Recognition, Policy [Policy Text Block]               | 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 is for annual reporting periods beginning after December 15, 2017. In July 2015, the FASB decided to defer by one year the effective date of this ASU. The ASU has not yet been adopted and will not have a material impact on our company’s financial position, cash flows or results of operations.                                                                                                                                                                                                                                                                                                                                                                                                             |

ASU 2014-12 requires that performance targets that affect vesting and that could be achieved after the requisite service period be treated as performance conditions. The effective date of ASU 2014-12 is for interim and annual reporting periods beginning after December 15, 2015. The ASU has not yet been adopted and will not have a material impact on our company’s financial position, cash flows or results of operations.                                                                                                                                                                                                                                                                                                                                                                                                                           |

The effective date of ASU 2015-02 is for interim and annual reporting periods beginning after December 15, 2015. The ASU has not yet been adopted and will not have a material impact on our company’s financial position, cash flows or results of operations.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         |
| Interest Capitalization, Policy [Policy Text Block]           | ASU 2015-03, Interest-Imputation of InterestIn April 2015, the FASB Issued ASU 2015-03, Interest-Imputation of Interest. ASU 2015-03 reduces the complexity of disclosing debt issuance costs and debt discount and premium on the balance sheet by requiring that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The effective date of ASU 2015-03 is for interim and annual reporting periods beginning after December 15, 2015. The ASU has not yet been adopted and will not have a material impact on our company’s financial position, cash flows or results of operations.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                |

| - Definition
Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.
