The Man page says:

ENV    If this variable is set, then parameter expansion, command substitution, and arithmetic substitution are performed on the value to generate the pathname of the script that will be exe
                     cuted  when  the shell is invoked interactively (see Invocation below).  This file is typically used for alias and function definitions.  The default value is $HOME/.kshrc.  On systems
                     that support a system wide  /etc/ksh.kshrc initialization file, if the filename generated by the expansion of ENV begins with /./ or ././ the system wide initialization file  will  not
                     be executed.

When I run echo $ENV It outputs /usr/share/Modules/init/profile.sh which says:
Code:
# get current shell name by querying shell variables or looking at parent
# process name
if [ -n "${BASH:-}" ]; then
   shell=${BASH##*/}
elif [ -n "${ZSH_NAME:-}" ]; then
   shell=$ZSH_NAME
else
   shell=$(/usr/bin/basename $(/usr/bin/ps -p $$ -ocomm=))
fi

if [ -f /usr/share/Modules/init/$shell ]; then
   . /usr/share/Modules/init/$shell
else
   . /usr/share/Modules/init/sh
fi

shells(4)							   File Formats 							 shells(4)

NAME

       shells - shell database

SYNOPSIS

       /etc/shells

DESCRIPTION

       The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
       shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.

       A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by  the  routines
       which search the file. Blank lines are also ignored.

       The  following  default	shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh,
       /bin/tcsh,  /bin/zsh,  /sbin/jsh,  /sbin/sh,  /usr/bin/bash,  /usr/bin/csh,  /usr/bin/jsh,  /usr/bin/ksh,  /usr/bin/pfcsh,  /usr/bin/pfksh,
       /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh. Note that /etc/shells overrides the default list.

       Invalid shells in /etc/shells may cause unexpected behavior (such as being unable to log in by way of ftp(1)).

FILES

       /etc/shells	       lists shells on system
