The iShares website currently reports 30 day SEC yield at 5.63% for TIP, and 6.09% for STIP which I'm considering instead for its lower interest rate risk. Historically, the STIP distributions have been lower than TIP as would expect, but how can the current SEC yield be higher? Is there something like contango happening with their yield curve? And does the SEC yield being higher than the trailing distribution yield imply that upcoming distributions will be higher?
With regard to your request, the information we have on the calculation is the definition that is posted in the box next to the figure on the website. The short of what it says is the figure represents interest earned during the period after deducting the fund’s expenses for the period.

Not much help from i-shares in their reply, just points to the info in the box next to the yield on their site.
