In a move that comes as a bit of a head-scratcher, Cedar Fair (NYSE:FUN) announced that it would be raising as much as $250 million in a secondary offering of its limited partnership units.

Don't get me wrong here. Cedar Fair can certainly use the money after agreeing to buy the entire Paramount Parks chain from CBS (NYSE:CBS) for $1.24 billion last month. The thing is that the company had also secured $2 billion in debt financing to seal that deal. Cedar Fair plans to use the money from the offering to partially repay the earlier debt financing.

Isn't stock financing preferable to taking on debt in these interest-rate-sensitive days? Sometimes. Not this time.

One of the primary attractions about Cedar Fair is its beefy quarterly distributions. The units are yielding a huge 7.1%, and during last month's conference call, company officials expressed their commitment to keep the chunky payouts coming. It's one of the reasons why Mathew Emmert was drawn to the well-run regional amusement park operator, recommending the units to Income Investor newsletter service subscribers last year.

So what's going on here? A company in Cedar Fair's position would be paying hundreds of basis points more through more conventional financing, but printing new units won't come free. It will still be on the hook for more quarterly distributions. So excuse me for blurring clarity with cynicism, but why is Cedar Fair diluting its unitholders and enriching the offering's underwriters?

I was at both the company's flagship Cedar Point park and Paramount's Kings Island park (a key park in the Paramount purchase) last week. I really like how the pieces will fit together and I will be back Thursday to elaborate on my trek through six amusement parks and four indoor water parks. I just don't like it when a high-yielding investment like Cedar Fair chooses equity over debt when the realized savings won't be as great as if a company like rival Six Flags (NYSE:SIX) -- with a yield of nil on its common stock -- were doing the same thing.
