Ok, just did a quick read of the actual SEC instructions, and my earlier post appears correct. As long as SLTD's public float was $75 million or greater w/in 60 days of filing, it was eligible to file the S3 without being subject to the 1/3 rule and also despite being traded OTC.
If you look at the instructions, you can verify this by seeing SLTD would qualify under provision 1.B.1. (on top of pg. 4), and therefore need not qualify under the alternative in provision 1.B.6. (bottom of pg. 5- top of pg. 6). http://www.sec.gov/about/forms/forms-3.pdf
Also, the preliminary-type filing that SLTD did is permissible under 1.B.1. qualification, but does not appear permissible under a 1.B.6. qualification. (Per 2.F. on bottom of pg. 8)
