comment What are current interest rates on senior/junior/mezzanine loans for e.g. real estate developers?
inginvestment.com/idc/groups/public/documents/… Here, for example, I found a value of 4.5% for a senior loan (page5), but it does not say anything on the runtime, the conditions, etc.

Okay thanks, but that is not part of the exercise! Let's assume there is no such future! -Marie

I forgot that we always know that $Z=100$. Thank you very much.

comment Calculate the “ten year zero rate” given two bonds with two prices
Okay, so that confirms my initial thought, but how exactly do you get $\approx 3.57\%$, because I only get a value of $\approx -0.311$ when I type this into Mathematica as follows: $\verb{NSolve[{0.04*Z*Sum[Exp[-y*k], {k, 1, 10}] == 10,70 == Exp[-y*10]*Z},{y, Z}]}$ Does anyone see what I do wrong?

comment Calculate the “ten year zero rate” given two bonds with two prices
I'm especially curious now because, when I try to solve this system, I only get $y\approx -0.311$, and I don't think that $y$ should have a negative value here...

comment What are the limits of bond portfolio immunization against interest rate changes?
Hello, the article is called "Duration, Convexity, and Time Value" by christensen and Sorensen, taken from The Journal of Portfolio Management, page 58.
