As well, our websites resource in our Russian organization is now up to $700 billion, down from around a great mil dollars on yearend.
And the currency translation improvement, or CTA, associated with the net money really stands during the a great billion dollars. nine million, with about $1 mil having head exposures to Russia and one just as much as $900 billion for larger has an effect on because of the macroenvironment.
