CUSIP & Stock Splits

I believe Quicken uses CUSIP numbers to link downloaded stock data to tickers in your data file. I also believe the CUSIP number changes (last 3 characters) when a stock splits.

Now this results in the same ticker being listed twice in the security list (different CUSIP numbers).

When you enter a stock split transaction you get to pick 'security name', the number of 'new shares' and the number of 'old shares'.

How is this supposed to work?

Is 'security name' the old entry in the security list or the new entry?

Stock data should be sourced from old security list entry before the split (and adjusted appropriately) and from the new security list entry after the stock split. How is this possible if you only specify one the security list entry in your stock split transaction?

I guess I could ask what is the proper way of handling stock splits (assuming CUSIP changed)? What kind of account transactions should I have in my account register?

I see some of my downloaded accounts (Pershing and Fidelity) have 3 transactions: The split transaction which has no impact on the account value & holdings, a remove stock transactions (old CUSIP) and a add stock transaction (new CUSIP). This seems to do the job but also seems cumbersome. Now to compute performance you would to remember to include all the security entries associated with a particular ticker. Quicken must have a better way to handle this?
