| Marketable Securities                                     | Marketable SecuritiesMarketable securities can consist of certificates of deposits, commercial paper, corporate bonds and other investments with established commercial banking institutions with readily determinable fair values and stated maturities of greater than three months.  We determine the appropriate classification of our investments in marketable securities at the time of purchase and reevaluate such designation at each balance sheet date.  Our marketable securities are classified as available for sale and have original maturity dates from 90 to 365 days.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        |
| Adopted and Recently Issued Accounting Pronouncements     | Adopted and Recently Issued Accounting PronouncementsIn June 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period, which provides guidance requiring that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. This is effective for the fiscal years and interim reporting periods beginning after December 15, 2015. We are currently evaluating the impact that the adoption of ASU 2014-12 will have on our consolidated financial statements or related disclosures.In May 2014, FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which converges the FASB and the International Accounting Standards Board standard on revenue recognition. Areas of revenue recognition that will be affected include, but are not limited to, transfer of control, variable consideration, allocation of transfer pricing, licenses, time value of money, contract costs and disclosures. This is effective for the fiscal years and interim reporting periods beginning after December 15, 2016. We are currently evaluating the impact that the adoption of ASU 2014-09 will have on our consolidated financial statements or related disclosures.In April 2014, FASB issued ASU No. 2014-08, Presentation of Financial Statements and Property, Plant and Equipment: Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, which requires only disposals representing a strategic shift in operations that have a major effect on operations and financial results to be presented as discontinued operations. The guidance also requires expanded financial disclosures about discontinued operations and significant disposals that do not qualify as discontinued operations. This is effective for the fiscal years and interim reporting periods beginning after December 15, 2014. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements or related disclosures.In July 2013, FASB issued ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. ASU 2013-11 clarifies guidance and eliminates diversity in practice on the presentation of unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists at the reporting date. This new guidance is effective on a prospective basis for fiscal years and interim reporting periods within those years, beginning after December 15, 2013. We adopted the provisions of ASU 2013-11 beginning April 1, 2014.  The adoption of the ASU did not have any impact on our financial statements.  Management continually evaluates the potential impact, if any, of all recent accounting pronouncements on our consolidated financial statements or related disclosures and, if significant, makes the appropriate disclosures required by such new accounting pronouncements. |

Disclosure of accounting policy for investments in debt and equity securities that have readily determinable fair values (marketable securities). At a minimum, the disclosure might address accounting policies for investments classified as trading, available for sale, or held to maturity and may include how the entity determines whether impairments of available for sale or held to maturity investments are other than temporary, how the fair values of the entity's securities are determined, and the entity's accounting treatment for transfers between investment categories.
