Try putting a "http://" in front.

I.e.

<a href="http://www.exx.com" target="_blank">AnnualBudget</a>

"www" is not a protocol/scheme. HTTPS or HTTP are protocols.

Absolute URLs have to have a "scheme" in front, see details about URLs on Wikipedia.

Alternatively, this would also work:

<a href="//www.exx.com" target="_blank">AnnualBudget</a>

Update 1:

Since you comment that your input comes from the user, let me add this one:

enter image description here

(Although this refers to SQL injection, the same would be true for all user input).

Update 2:

To check the input for an absolute URL, do something like:

// Read from user input, e.g. (WebForms syntax!):
string my = MyTextBox.Text.Trim();

// Do some checking (this has be done much more thoroughly in real-life!)
if ( !my.StartsWith("http://") && !my.StartsWith("https://") )
{
    my = "http://" + my;
}

// Do something with "my", e.g. (again, WebForms syntax only):
MyHyperLink.NavigateUrl = my;

(Please note that I'm no MVC expert, the above pseudo-code uses WebForms syntax instead)
