"That is a very strange disconnect between SP, divi yield and NAV which I really don't understand."
I like to focus on the NAV, as that's based on a discounted cash flow (DCF) calculation, so should take into account the longer term, and not just the current yield and cover.
If you buy at NAV and if the cash flows turn out as assumed (and if they've done the maths correctly) then the rate of return (IRR) should equal the discount rate used in the DCF calculation. The latest published NAV per share was 90.6p, and the weighted average discount rate (levered) was stated to be 9.4%. As seems to be standard for other infrastructure funds I've looked at, the management fees (about 1% of NAV) are not included in the DCF calculation, so we need to deduct those, leaving an annual return (on NAV) of 8.4%. This is nominal, so I adjust for inflation by subtracting the long term inflation rate that is assumed in the DCF, namely 2%, to give a real return of 6.4%. But buying at the current 40% discount to NAV, this rises to 6.4/(1 - 0.4) = 10.6%. (This simplistic way of accounting for the discount is not strictly accurate, since it doesn't take into account the "duration" of the investment, but I believe it is erring on the low, conservative, side.)
Note that this assumes long term inflation of 2%. Personally I'm pessimistic about future inflation, and I think it's wise to consider the effect of higher inflation, let's say 5%. Based on SEIT's own sensitivity analysis, I reckon (very roughly) that 5% inflation would reduce the real returns to about 9%.
On this basis, the current yield of about 11.5% is probably not sustainable in real terms, but the expected returns are still very good.
Of course all of this assumes that the future cash flows turn out as assumed in the NAV calculation. Unfortunately I'm not able to make any assessment of those assumptions.But there are certain respects in which the NAV calculation and my calculation are conservative, and hopefully that will help to balance any over-optimism in the cash flow assumptions. Also, I'd be very happy with a real return of just 7%, so there's some margin of safety in that respect.
