Line of Credit	9. Line of Credit On May 26, 2016, the Company and certain of its subsidiaries entered into a credit agreement with Wells Fargo Bank, N.A. (the "Wells Fargo"). The credit agreement provides for a five-year senior secured revolving line of credit (the ‘‘line of credit") of $75.0 million. Availability under the line of credit is subject to a borrowing base which is redetermined from time to time based on certain percentage of certain eligible U.S. assets, including accounts receivable, inventory, real property, as well as machinery and equipment. The agreement includes sublimits of up to $25.0 million for letters of credit and $7.5 million of swing loans at the time there is more than one lender under the credit agreement. The line of credit expires on May 26, 2021 with all outstanding principal and interest due and payable on such date or an earlier date if declared due and payable on such earlier date pursuant to the terms of the credit agreement (by acceleration or otherwise). Subject to certain conditions of the credit agreement, the net cash proceeds from sales of certain collateral during the term of the arrangement are required to be used to prepay borrowings under the line of credit. The Company may also voluntarily prepay certain amounts under the line of credit without penalty or premium. There were no amounts outstanding under the line of credit as of September 30, 2017 and 2016. Borrowings under the line of credit bear an annual interest rate equal to, at the Company’s option, the base rate or the LIBOR rate plus, in each case, an applicable margin determined based on the Company’s liquidity as of the first day of each fiscal quarter. LIBOR rate is reset at the beginning of each selected interest period based on the rate then in effect. The base rate is a fluctuating interest rate equal to the highest of (i) the federal funds rate plus 0.50%, (ii) the one month LIBOR rate plus 1.00% and (iii) the prime lending rate announced by Wells Fargo. In addition to interest on any outstanding borrowings under the credit agreement, the Company is required to pay monthly fees of 0.25% per year related to unused portion of the revolver commitment amounts. The amount of such fees incurred during fiscal years ended September 30, 2017 and 2016 was insignificant. All outstanding borrowings under the credit agreement are guaranteed by the Company along with certain U.S. subsidiaries and secured by a first priority perfected security interest in substantially all of the Company’s and guarantor’s assets in the U.S., subject to certain exceptions. Additionally, the Company granted Wells Fargo a mortgage lien on certain company-owned real properties. The line of credit contains certain customary representations and warranties, a financial covenant, affirmative and negative covenants, as well as events of default. In the event in which the Company’s liquidity is less than the greater of (i) 12.5% of the commitments under the line of credit, and (ii) $9.4 million, and continuing until the time such liquidity during a 60‑consecutive day period has been equal to or greater than the greater of (a) 12.5% of the commitments under the line of credit, and (b) $9.4 million, the Company is required to maintain a fixed charge coverage ratio of at least 1.0 to 1.0 measured as of the last day of each fiscal month ending during such period. Liquidity is defined as a sum of (a) excess availability under the credit agreement; and (b) unrestricted cash and cash equivalents located in bank accounts in the United States that are subject to a control agreement in favor of Wells Fargo, limited to a maximum amount of 50% of liquidity. Negative covenants limit the Company’s ability to incur additional indebtedness, liens, sell assets, consolidate or merge with or into other entities, pay non-cash dividends (and cash dividends if the Company fails to meet certain payment conditions), make certain investments, prepay, redeem or retire subordinated debt, and enter into certain types of transactions with the Company’s affiliates. If any of the events of default occur and are not waived or cured within applicable grace periods, any unpaid amounts under the credit agreement, including principal and interest, may be declared immediately due and payable and the credit agreement may be terminated. The Company was in compliance with the line of credit covenants as of September 30, 2017 and 2016. On October 4, 2017, the Company entered into a $200.0 million Senior Secured Term Loan Facility (the “term loan”) with Morgan Stanley Senior Funding, Inc., JPMorgan Chase Bank, N.A. and Wells Fargo Securities, LLC (collectively, the “lenders”). Coincident with the entry into the term loan agreement, the Company amended certain terms and conditions of the credit agreement and entered into an arrangement with Wells Fargo Bank, N.A. and JPMorgan Chase Bank, N.A. Based on the amended terms of the credit agreement, the line of credit continues to provide for revolving credit financing of up to $75.0 million, subject to borrowing base availability. The line of credit matures on October 4, 2022 and expires no less than 90 days prior to the term loan expiration. Borrowing base availability under the amended line of credit excludes collateral related to fixed assets and is redetermined periodically based on certain percentage of certain eligible U.S. assets, including accounts receivable and inventory. The sublimits for letters of credit were reduced to $7.5 million under the amended terms of the credit agreement. All outstanding borrowings under the credit agreement are guaranteed by the Company and BioStorage Technologies, Inc., its wholly-owned subsidiary (“Guarantor”), and subordinated to the obligations under the term loan which are secured by a first priority lien on substantially all of the assets of the Company and the Guarantor, other than accounts receivable and inventory.
