Freeport-McMoRan in a World of Debt

FCX, which saw its last quarterly earnings growth drop by almost 22%, moves from being a company with around $3.5 billion in total debt to now having (according to Yu) more than $16 billion. Yu reportedly said this gigantic increase in debt is manageable with some capital spending maneuvers.

The market reaction created an enormous amount of selling of FCX shares on over 10 times average daily volume. FCX's $1.25 annual dividend, which had represented a payout ratio of 37% of the company's earnings, is the first big question mark many investors will face.

Unless renegotiated, Freeport will pay around $50 a share in cash and stock for Plains, representing a takeover premium of nearly 39% based on the company's closing share price, according to a statement by the company made on Wednesday.

Shareholders of McMoRan stock will get $14.75 in cash and 1.15 units of a royalty trust for each share. The terms of the transactions are supposed to close by the second quarter of 2013.

Part of the shock was how abruptly this mega-transaction was announced, and that it was at a time when FCX, the world's largest publicly traded copper company, has seen its share price performance matched by competitors like Southern Copper (SCCO) , which doesn't have the gold production and reserves that FCX has.
