  • Sell Transaction

The total merger consideration is $219.4333 per GW Pharmaceuticals share. This is $200 in cash and $19.4333 in Jazz Pharmaceuticals shares (0.12036 x 161.50). The opening price of Jazz Pharmaceuticals on the day after the merger completion date was $161.50. Calculate the total value received for your GW Pharmaceuticals shares by multiplying 219.4333 by the total shares of GW Pharmaceuticals owned.

  • Total Proceeds = [219.4333 x (# of GW Pharmaceuticals shares owned)] – (Reorganization fee).
  • For example, if you owned 100 GWPH shares your total proceeds would be (21943.33 – Reorganization fee).
  • Use the Suspense account to receive the sale proceeds.
  • Date this transaction 5/5/2021.


  • Transfer Cash Received

Transfer from the Suspense account to the Broker account (or bank if appropriate), all merger consideration cash received from this merger transaction. This will be the amount of the $200 per GW Pharmaceuticals share minus any reorganization fee charged.  If your Suspense account balance was zero when you entered the sell transaction above, then the balance after transferring the merger cash received will be the total purchase price of the Jazz Pharmaceuticals shares you received in this merger. For example, if you owned 100 GW Pharmaceuticals shares  your cash portion of the merger consideration was $20,000.00 – reorganization fee. ([200 x 100] –reorganization fee).

Any fractional shares received in this merger will likely be sold by your broker.

Enter a Sell transaction for the fractional shares dated 5/6/2021.

Note: In Merger with cash transactions, realized capital gains and the cost basis of the new shares have a component dependent on the price per share entered in the entry screens. In our experience brokers tend to use the price per share published by the companies on their websites in their guidance to shareholders. If the companies publish guidance with a share price, we use that share price in our instructions to minimize possible differences between the accounting records and broker information. In cases where no guidance is available, we will choose the lower of the opening or closing price on the effective date. Either of these prices is acceptable to the IRS and by choosing the lower price some realized capital gains will be deferred to a later date. However, there is always the chance the price we choose will not be the price chosen by your broker. The gain from the merger and cost basis of the new shares recorded in your accounting records will then differ from your broker information. Because of the lack of detail in the tax code, both our choice and your broker’s choice would be reasonable estimates of market value for the shares received. Your records are NOT incorrect because they differ from your broker. Tax return forms do have specific areas to report these usually small differences. Our tax printer software handles these adjustment entries automatically in the normal operation of the software.
