Hi, I would please ask you if the expressions in bold are correct in the following:
I also appreciate X Inc.'s demonstrated capacity/capability to successfully tackle the issues that the project finance industry has experienced/(been experiencing) in/over the last few years which have seen a shift/trend from social infrastructure investments to economic infrastructure projects, which tend to be more complicated and present more risks (than (the former/social infrastructure deals). do you need it?).

Thank you, FounDit, for your suggestions. I only have a couple of questions.
Why do you suggest using which have shifted rather than which have seen a shift? Is it the latter expression incorrect, or is it just a matter of style?
Is which have shifted referred to issues or to years?
Which of the adverbs in bold (if any) you think is the most appropriate in: ... from social infrastructure investments to generally/basically more complicated and riskier economic infrastructure projects.

Thank you, FounDit. I thought that you need an adverb to not lose the meaning of tend to, that otherwise would not be conveyed in the modified expression ... to more complicated and riskier economic infrastructure projects. What do you think?

I saw that description as being unnecessary to the main ideas. The fact that something "tends" or has a "tendency" to be a certain way simply means it has a predisposition for that.

That being so, I simply stated that as a fact rather than describing it as "tends" to be that way. Omitting it made the sentence shorter, but still left the ideas intact.
