RadioShack has adequate liquidity, with $566 million in cash and cash equivalents and an unused $450 million credit facility as of March 31, 2012. The credit facility expires on Jan. 4, 2016. Availability on the facility would be reduced by 12.5% ($56.3 million) if the fixed charge coverage ratio drops below 1x, though this would not have a material impact on RadioShack's liquidity. Fitch notes that the calculation of fixed charge coverage has been amended to exclude the $49.6 million dividend payment made on Dec. 15, 2011, providing some near-term relief to this covenant.
