Is there problems with using a class like this?

I want to extend the scope of a particular object to all of my classes.  This is a single threaded application.  Is this a bad approach?  and if so what suggestions would you have for me(i.e. examples)?  What if any are is the downside to this approach?  What is the normally accepted approach to this issue?
using System;
using System.Collections.Generic;
using System.Text;
using System.Data;
using nsoftware.IBizQB;
 
namespace myExampleClass
{
    class Example
    {
        private bool InitializeQBCustomer()
        {
            bool bSuccess = false;
            try
            {
                if (AC.CustomerMain == null)
                { AC.CustomerMain = new Customer(); }
                else
                { AC.CustomerMain.Reset(); }
                bSuccess = true;
            }
            catch
            {
                //handle problems
            }
            return bSuccess;
        }
    }
}
 
//In separate class
 
using System;
using System.Collections.Generic;
using System.Text;
using System.Data;
using nsoftware.IBizQB;
 
namespace myExampleClass
{
    class AC
    {
        public static nsoftware.IBizQB.Customer CustomerMain;
    }
}

If your app is SINGLE threaded then there should be no problem at all...

Can't see any problems.
Really, the approach is very similar to a singleton pattern.
You just added resetting to it.

Just in case - here is an interesting article on multythreaded singleton:

Thanks for the affirmation.  I just wanted to be sure I was coding this correctly.
