Debt interest terms The Credit Facility is subject to a borrowing base, calculated using a formula based upon eligible receivables and inventory, minus certain reserves and subject to restrictions. The borrowing base as of March 29, 2014 was approximately $390.0 million. Borrowings under the Credit Facility will bear interest at an index based on LIBOR or, at the option of the Company, the Base Rate (defined as the highest of (a) the SunTrust prime rate, (b) the Federal Funds Rate plus 0.5% and (c) one-month LIBOR plus 1.00%), plus, in either case, an applicable margin based on the Company’s total outstanding borrowings. Such applicable margin for LIBOR-based borrowings fluctuates between 1.25%-1.75% (and was 0% at March 29, 2014) and such applicable margin for Base Rate borrowings fluctuates between 0.25%-0.75% (and was 0% at March 29, 2014).
