Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	(6) Commitments and Contingencies Customer Supply Agreement During 2016, the Company entered into a supply agreement and a side agreement (together, the Supply Agreement) and a joint development agreement (the JDA) with BASF SE (BASF). Pursuant to the Supply Agreement, the Company will sell exclusively to BASF the Company’s Spaceloft ^® A2 product at annual volumes to be specified by BASF, subject to certain volume limits. The Supply Agreement will terminate on December 31, 2027. Upon expiration of the Supply Agreement, the Company will be subject to a post-termination supply commitment for an additional two years. The JDA is designed to facilitate the collaboration between the parties on the development and commercialization of new products. In addition, under the terms of the Supply Agreement, BASF will make a non-interest bearing prepayment to the Company in the aggregate amount of $22 million during the construction of the Company’s planned manufacturing facility in Statesboro, Georgia (Plant Two), subject to the Company’s prior satisfaction of certain preconditions, including securing a debt commitment from a third party lender for at least $30 million. BASF is obligated to pay the prepayment to the Company in eight equal consecutive quarterly installments commencing on the first day of the calendar quarter following the date on which the preconditions are met. Once commenced, BASF’s obligation to make such quarterly payments shall be subject to postponement in the event of delays of three months or more in the projected date of completion of Plant Two by a commensurate number of months. After October 1, 2018, the Company will, at BASF’s instruction, credit up to 25.3% of any amounts invoiced by the Company for Spaceloft ^® A2 product sold to BASF against the prepayment balance. However, BASF has no obligation to purchase products under the Supply Agreement. If any of the prepayment remains uncredited against amounts invoiced by the Company as of September 30, 2023, BASF may request that the Company repay the uncredited amount to BASF in four equal quarterly installments beginning on December 31, 2023. The repayment obligation will be secured by a security interest in real estate, plant and equipment at the Company’s Rhode Island and Georgia manufacturing facilities. As of March 31, 2017, the Company anticipates that the impact of constrained capital investment and low activity levels in the global energy markets will continue through 2017. With this view of the market, the Company has elected to temporarily delay the board approved Plant Two project and its related financing to better align the capacity expansion with the Company’s assessment of demand for the 2018 to 2020 period. As a result, the Company has yet to fulfill the prepayment preconditions and commencement of the quarterly prepayments from BASF will be delayed until the preconditions are satisfied. Revolving Line of Credit The Company entered into an Amended and Restated Loan and Security Agreement with Silicon Valley Bank (Loan Agreement), on August 31, 2014, which has been subsequently amended from time to time. On January 27, 2017, the Loan Agreement was amended to extend the maturity date of the revolving credit facility to January 28, 2018. Under the Loan Agreement, the Company may borrow up to $20 million subject to compliance with certain covenants and borrowing base limitations. At the Company’s election, the interest rate applicable to borrowings may be based on the prime rate or LIBOR. Prime rate-based rates vary from prime rate plus 0.75% per annum to prime rate plus 1.75% per annum, while LIBOR-based rates vary from LIBOR plus 3.75% per annum to LIBOR plus 4.25% per annum. In addition, the Company is required to pay a monthly unused line fee of 0.5% per annum of the average unused portion of the facility. The Company’s obligations under the Loan Agreement are secured by a first priority security interest in all assets of the Company, including those at the East Providence facility, except for certain exclusions. At March 31, 2017 and December 31, 2016, the Company had no amounts drawn on the revolving credit facility. Under the Loan Agreement, the Company is required to comply with both non-financial and financial covenants, including minimum Adjusted EBITDA and minimum Adjusted Quick Ratio, as defined.

As of January 31, 2017, these obligations were released by the landlord. In addition, the Company has been required to provide certain customers with letters of credit securing obligations under commercial contracts. The Company had outstanding letters of credit backed by the revolving credit facility of $2.4 million and $2.7 million at March 31, 2017 and December 31, 2016, respectively, which reduce the funds otherwise available to the Company under the facility. Based on the available borrowing base, the effective amount available to the Company under the revolving credit facility at March 31, 2017 was $9.7 million after consideration of the $2.4 million of outstanding letters of credit.
