Hi Yaroslav,
On one hand, there is a limit in redirect chains where GoogleBot is capable of handling: Up to 5 redirects.
Matt Cutts said it in these videos:
Can too many redirects from a single URL have a negative effect on crawling? Is there a limit to how many 301 (Permanent) redirects I can do on a site?
On the other hand, being under that 5 redirects, I do believe that the authority is passed through redirections. Also believe that there is some minimum loss there, as always the best case scenario is to not have any redirection, arround 5-10% in the whole chain.
There are two discussions here.
- Google saying that Any 30x redirect pass the whole authority, just another way of saying that redirects dont lose PageRank.
- Some studies and experts confirming that there is some lost in authority/PageRank in any redirect.
As this is an old discussion, I do recommend you to read the post from the greatest Cyrus Sheperd about those two arguments:

Hope it helps.
Best luck.
