On April 23, 2012, the Company amended its revolving line of credit facility to (i) extend the maturity date of such facility by two years to April 30, 2014, (ii) decrease the unused revolving line commitment fee from 0.1875% per annum to 0.10% per annum, and (iii) reduce the minimum interest rate on borrowings from 5.75% to 3.0% per annum. The instrument governing the line of credit facility includes certain financial covenants regarding tangible net worth. The revolving line of credit agreement includes a provision for the issuance of commercial or standby letters of credit by the bank on behalf of the Company. The value of all letters of credit outstanding reduces the total line of credit available. The revolving line of credit is collateralized by a blanket lien on all of the Company’s domestic assets excluding intellectual property and real estate. The minimum borrowing interest rate is 3.0% per annum. Borrowing is limited to the lesser of (a) $7.5 million plus the borrowing base, or (b) $20 million. The borrowing base available as of December 29, 2012 was $13.5 million. As of December 29, 2012, the Company was not in breach of any restrictive covenants in connection with this line of credit. There were no outstanding amounts drawn on this facility as of December 29, 2012. Although management has no current plans to request advances under this credit facility, the Company may use the proceeds of any future borrowing for general corporate purposes, future acquisitions or expansion of the Company's business. In July 2008, the Company entered into a mortgage agreement with General Electric Commercial Finance ("GE") pursuant to which it borrowed $13.5 million. The mortgage initially bears interest at the rate of 7.18% per annum, which rate will be reset after five years to 3.03% over the then weekly average yield of five-year U.S. Dollar Interest Rate Swaps as published by the Federal Reserve. Monthly principal and interest payments are based on a twenty year amortization for the first sixty months and fifteen year amortization thereafter. The remaining principal balance of the mortgage and any accrued but unpaid interest will be due on August 1, 2018. The mortgage is secured, in part, by a lien on and security interest in the building and land comprising the Company’s principal offices in Milpitas, California. GE subsequently sold the mortgage on March 31, 2011 to Sterling Savings Bank; however, no changes were made to the terms of the original loan agreement with GE as a result of the sale. According to the terms of the loan agreement, the Company can make annual pre-payments of up to 20% of the outstanding principal balance without incurring any penalty. In July 2011, the Company prepaid $1.95 million, representing 20% of the outstanding balance. In July 2012, the Company prepaid $1.4 million, representing 20% of the outstanding balance. At December 29, 2012, future annual maturities of all debt obligations were as follows (in thousands):
Fiscal years | Amount
2013 | $ | 928 |
2014 | 998 |

The Company estimates the fair value of its debt based on discounted cash flows with inputs that are observable in the market or that could be derived from, or corroborated with observable market data (referred to as Level 2), including interest rates based on yield curves of similar debt issued by parties with credit ratings similar to the Company. The estimated fair value of the debt as of December 29, 2012 and December 31, 2011 was $5.7 million and $8.3 million, respectively.
