Dunno if anyone here still owns or cares about these (since OSM maturing very soon, ISM in a year). But the 2016 dividend payments look too low to me. Anyone care to check my math ? Left hand column is per/share payment I computed, right-hand is what I received (for Jan thru Dec):
$0.042760 $0.042713
$0.047149 $0.047027
$0.050686 $0.050553
$0.059017 $0.058867
$0.070337 $0.070140
$0.065138 $0.064966
$0.059641 $0.059490
$0.067417 $0.067228
$0.065233 $0.065048
$0.062789 $0.062621
$0.061259 $0.061090
$0.063998 $0.063834
Not much, amounting over all of 2016 to about a $2.70 shortfall on my 1500 share position. Still, makes me wonder if something fishy is going on. Reminds me of a friend of friend who was working on GIS systems in school, and thought he'd determined that highway contractors were very slightly, but consistently, over-billing the state for miles of road work. (Dunno what ever became of that).
Only thing I can figure is that month-to-month inflation from Sep'14 to Sep'15, which would determine Jan'16 interest payment, was negative, and somehow I'm not allowing for how that might propagate over the remaining of 2016's payments properly. I don't think so though: unless the month-to-month is more negative than the bond's real interest rate (2.05% for ISM), its negativity don't signify).
BTW, I have a huge sense of deja-vu on this, so if I've had this issue before, and was set straight, please be gentle.
