Entry #2, we like where you are headed with this design, The i inside the K is really neat. Please try a more deep vibrant blue, this blue is a little pale and boring, and perhaps play the with the design a bit. We like the font used for Kronos. International Investments needs to be larger.
#4 We like the logo, however we feel that it has been done before... Perhaps play with the design and come up with something more unique? Also the International investments is too small to read.
