There is nothing wrong with your code, but it is not extensive enough. Try using the code below, this covers every aspect of your Leverage Browser Caching. Except for external files.:

<IfModule mod_expires.c>
ExpiresActive On

## IMAGES ##
ExpiresByType image/jpg "access plus 1 year"
ExpiresByType image/jpeg "access plus 1 year"
ExpiresByType image/gif "access plus 1 year"
ExpiresByType image/png "access plus 1 year"
ExpiresByType image/x-icon "access plus 1 year"

## CSS ##
ExpiresByType text/css "access plus 1 month"

## HTML ##
ExpiresByType text/html "access plus 1 month"

## JAVASCRIPT ##
ExpiresByType text/javascript "access plus 1 month"
ExpiresByType text/x-javascript "access plus 1 month"
ExpiresByType application/javascript "access plus 1 month"
ExpiresByType application/json "access plus 1 month"
ExpiresByType application/x-javascript "access plus 1 month"
ExpiresByType application/x-shockwave-flash "access plus 1 month"

</ifModule>
