SAC Capital decreased its MNTA holding from 2.94M shares on 3/11/14 to 2.40M shares now, according to a 13G/A filed today:

http://www.sec.gov/Archives/edgar/data/1235010/000089914014000378/m11658447.htm

Using the SEC formula for ownership stake, SAC now owns 4.6% of MNTA, and hence it no longer meets the 5% threshold for reporting on Form 13G. Thus, we won’t see further form 13G filings from SAC unless it buys back enough shares to exceed the 5% threshold. (SAC’s MNTA holding will still be able to be tracked quarterly, with a 45-day delay, on Form 13F-HR.)

Primecap Management owned 2.77M shares of MNTA as of 4/30/14, according to a 13G filing today:

Primcap’s holding constitutes a 5.3% equity stake using the SEC’s formula and a 5.1% stake using the 54.3M diluted share count I use for valuation purposes (#msg-76922372). This is the first time Primecap has been a 5%+ shareholder of MNTA.

MNTA Major Shareholders

[Updated for 13G filings since 3/12/14 (previous version of table).]


The table below shows the shareholdings of all MNTA shareholders
who filed SEC Form 13G during the past 12 months; the table
entries are not updated from quarterly filings on Form 13F-HR,
and hence they may not coincide precisely with the amounts shown
on Form 13F-HR; however, the figures in the table below should be
close enough for investment purposes.

The percentages in the table are based on 54.3M diluted shares
(#msg-76922372) and do not concur with the percentages on
SEC Form 13G, which uses a different formula.
