The stock split assistant treats cash-in-lieu as a straight payment and prompts for accounts to pay the amount into and an income account to balance it. This is wrong.

Cash-in-lieu is a sale of the fractional shares remaining after a split. For example, if one has 137 shares of XYZ and it splits 3:1, one gets 45 2/3 shares after the split, but stocks don't generally provide fractional shares unless kept as book-keeping entry when participating in a company-sponsored dividend reinvestment program (DRIP), so the company buys the 2/3 of a share, usually at the price the stock trades at at the instant after the split. The stock assistant should either ask for or calculate the residual shares and make the price-in-lieu splits reflect an asset exchange.
