I believe all of the 8-Ks, 10-Ks, and 10-Qs for SIML tells the truth. The revenues to be generated are still in purchase order mode and revenues have not been captured yet, but it's coming.
When such happen, then you will see the revenues reflected within the 10-Ks and 10-Qs. Purchase Orders are legitimate contractual agreements of a promise to execute such business transaction.
