Oct 17, 2011. /Lesprom Network/. Louisiana-Pacific Corporation has executed a fourth amendment, dated October 14, 2011, to its loan and security agreement (the “Revolving Credit Agreement”), dated March 10, 2009, with the lenders party thereto and Bank of America, N.A., as administrative agent, as the company said in a press release received by Lesprom Network. “We are very pleased with this amendment and the strong support LP has received from our banks,” Treasurer Mark Tobin said. “This facility, as amended, provides LP with greater flexibility over a longer term and at attractive pricing. As we continue to navigate through a very difficult housing market, it is important to have the certainty that stable, long-term liquidity lines provide. We believe this to be crucial to our operations and investors as we move forward.” Louisiana-Pacific Corporation is a leading manufacturer of quality engineered wood building materials including OSB, structural framing products, and exterior siding for use in residential, industrial and light commercial construction.
