NVS’ 10b5-1 selling has (as of 8/26/16) reduced NVS’ holding in MNTA to 3.32M shares: https://www.sec.gov/Archives/edgar/data/1114448/000110465916142120/a16-17495_1sc13da.htm On 8/10/16 (the date of the previous 13D filing), NVS owned 4.45M shares. p.s. Now that NVS’ equity stake in MNTA has fallen below 5%, no additional 13D filings are necessary, as far as I know.
