Chesapeake shares drop as loan increased to $4 billion Tue May 15, 2012 10:40am EDT (Reuters) - Shares in Chesapeake Energy Corp dropped as much as 6.5 percent early Tuesday after sources said the natural gas producer had increased a new bridge loan to $4 billion from $3 billion. The company, which faces a funding shortfall of about $10 billion this year, said on Friday that Goldman Sachs and Jefferies Group would provide it with $3 billion. The move was designed to give the company more breathing room to sell assets. Shares in Chesapeake dropped as low as $14.52, before recovering to $15.18, off 32 cents.
