Research and development (R&D) expenses for the first quarter 2013 totaled $9.2 million, representing a $0.3 million decrease from the $9.5 million recorded in the fourth quarter of 2012. First quarter 2013 R&D expenses increased $0.8 million from $8.4 million recorded in the first quarter 2012, mainly due to higher payroll and related expenses.
General and administrative (G&A) expenses for the first quarter of 2013 were $14.7 million, a decrease of $5.5 million from the $20.2 million recorded in the fourth quarter of 2012, primarily due to start-up activities related to the Columbus facility reported as part of G&A through February 2013. First quarter 2013 G&A expenses increased $6.6 million from $8.1 million reported in the first quarter 2012, due to $4.7 million higher start-up related activities at the Columbus facility and $1.9 million higher payroll and related expenses.
Capital investments during the first quarter were $4.8 million, primarily related to front end engineering and design of KiOR's 1,500 bone dry ton per day project in Natchez, Mississippi.
KiOR had cash and cash equivalents of $11.1 million at March 31, 2013, which represents a $29.8 million decrease from the December 31, 2012 balance. This decrease was primarily driven by operating uses of cash and capital expenditures on the Natchez facility. Net long-term debt stood at $120 million as of quarter-end. During the first quarter of 2013, the Company amended its 4-year-term loan to, among other things, extend KiOR's ability to pay interest in kind, defer principal amortizations, and increase the facility to $125 million to provide additional operating liquidity. As of the end of the first quarter of 2013, $50 million of this expanded facility remained undrawn and available upon the Company's request.
