| Effective Income Tax Rate Reconciliation, at Federal Statutory Income Tax Rate | 4.60% | 39.90% | |

| Incometax Uncertainties Description | The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount which is more than 50% likely of being realized upon ultimate settlement. The Company reevaluates these tax positions quarterly and makes adjustments as required. | ||
