This is the first time...

"This is the first time criminal action has been taken against any senior bankers for events dating to the 2008 financial crisis." (The Guardian.)

This - a subject;

is - a predicator (a linking verb);

the first time criminal action has been taken against any senior bankers for events dating to the 2008 financial crisis - a complement where:

"the first time" is a noun phrase;

"criminal action has been taken against any senior bankers" the complement of "the first time" ;

"for events dating to the 2008 financial crisis" an adjunct (adverbial).

Is my parsing acceptable?
