|Accounting Policies [Abstract]|
|Revenue [Policy Text Block]||Net revenue includes gross revenue less sales discounts, customer rebates, sales incentives, and product returns, all of which require the Company to make estimates for the portion of these allowances that have yet to be credited or paid to customers. The Company estimates these allowances using the expected value method, which is based upon historical rates and projections of customer purchases toward contractual rebate thresholds.|
|Revenue Recognition, Deferred Revenue [Policy Text Block]||
The balance in receivables from long-term manufacturing contracts at December 31, 2020 and September 30, 2020 was $158.9 and $138.1, respectively. The change was driven by the impact of net revenue recognized prior to billings. The balance in the liabilities from long-term manufacturing contracts and advances at December 31, 2020 and September 30, 2020 was $214.1 and $189.1, respectively, and consists primarily of cash payments received or due in advance of satisfying performance obligations. The revenue recognized for the three months ended December 31, 2020 and 2019 related to liabilities from long-term manufacturing contracts and advances as of September 30, 2020 and 2019 was $80.1 and $55.3, respectively.
