I finally found it!
Johnson Controls International PLC FORM 8-K/A
(Amended Current report filing)
Filed 10/03/16 for the Period Ending 09/02/16 from http://investors.johnsoncontrols.com/financial-information/johnson-sec-filings, says on page II-6: (my emphasis for the relevant paragraph)
On September 2, 2016, Johnson Controls and Tyco completed their
combination pursuant to the Agreement and Plan of Merger (the “Merger
Agreement”), dated as of January 24, 2016, as amended by Amendment No.
1, dated as of July 1, 2016, by and among Johnson Controls, Tyco and
certain other parties named therein, including Jagara Merger Sub LLC, an
indirect wholly owned subsidiary of Tyco (“Merger Sub”).
Pursuant to the terms of the Merger Agreement, on September 2, 2016,
Merger Sub merged with and into Johnson Controls with Johnson Controls
being the surviving corporation in the merger and a wholly owned,
indirect subsidiary of Tyco (the “merger”).
Following the merger, Tyco changed its name to “Johnson Controls
International plc.”
Immediately prior to the merger and in connection
therewith, Tyco shareholders received 0.955 ordinary shares of Tyco
(which shares are now referred to as “combined company ordinary shares”)
for each Tyco ordinary share they held by virtue of a 0.955-for-one
share consolidation. In the merger, each outstanding share of common
stock, par value $1.00 per share, of Johnson Controls (“Johnson Controls
common stock”) (other than shares held by Johnson Controls, Tyco and
certain of their subsidiaries) was converted into the right to receive
either the cash consideration or the share consideration (each as
described below), at the election of the holder, subject to proration
procedures described in the Merger Agreement and applicable withholding
taxes.
The election to receive the cash consideration was undersubscribed. As a
result, holders of shares of Johnson Controls common stock that elected
to receive the share consideration and holders of shares of Johnson
Controls common stock that made no election (or failed to properly make
an election) became entitled to receive, for each such share of Johnson
Controls common stock, $5.7293 in cash, without interest, and 0.8357
combined company ordinary shares, subject to applicable withholding
taxes.
Holders of shares of Johnson Controls common stock that elected to
receive the cash consideration became entitled to receive, for each such
share of Johnson Controls common stock, $34.88 in cash, without
interest, subject to applicable withholding taxes.
In the merger, Johnson Controls shareholders received, in the aggregate,
approximately $3.864 billion in cash. Immediately after the closing of,
and giving effect to, the merger, former Johnson Controls shareholders
owned approximately 56% of the issued and outstanding combined company
ordinary shares and former Tyco stockholders owned approximately 44% of
the issued and outstanding combined company ordinary shares.
This answers what actually happened in the transaction; as far as my cost basis in the new JCI, it's a little more obscure; on page II-7 it says:
For pro forma purposes, the valuation of consideration transferred is
based on, amongst other things, the adjusted share price of Johnson
Controls on September 2, 2016 of $47.67 per share
and on page II-8:
Johnson Controls adjusted share price as of September 2, 2016 (2): $47.67
(2) Amount equals Johnson Control closing share price and market
capitalization at September 2, 2016 ($45.45 and $29,012 million,
respectively) adjusted for the Tyco $3,864 million cash contribution
used to purchase 110.8 million shares of Johnson Controls stock for
$34.88 per share.
and both agree with the information posted at http://www.secinfo.com/dpdtb.w6n.2n.htm#1stPage (R66 Merger Transaction Fair Value of Consideration Transferred (Details)) which I can't seem to find on an "official" website but it purports to post from the SEC EDGAR database.
So for each share of JCI, it had a fair value of $47.67 prior to the acquisition, and transformed into $5.7293 in cash, plus 0.8357 of "new" JCI shares with a basis of $47.67 - $5.7293 = $41.9407. Stated in terms of "new" JCI shares, this is $50.1863 (=$41.9407/0.8357) per "new" JCI share.
(I'm not really 100% sure of this calculation though.)
I also found JCI's Form 8937 which states
Fair market value generally is the price at which property would change hands between a willing buyer and a willing seller, neither being under any compulsion to buy or sell and both having reasonable knowledge of the facts. U.S. federal income tax law does not specifically prescribe how former JCI shareholders should determine the fair market value of the Tyco ordinary shares received in the merger.
One possible method of determining the fair market value of one Tyco ordinary share is to use the average of the high and low trading prices on the date of the merger, which was $45.69.
Other methods for determining the fair market value of Tyco ordinary shares are possible. Former JCI shareholders are not bound by the approach described above and may, in consultation with their tax advisors, use another approach.
as well as similar text on the IRS website:
One possible method of determining the fair market value of one Tyco ordinary share is to use the average of the high and low trading prices on the date of the merger, which was $45.69.
Using this figure, former JCI shareholders that elected to receive shares in the merger would receive cash and Tyco ordinary shares worth approximately $43.91 per share of JCI common stock exchanged in the merger (assuming no cash received in lieu of fractional shares).
