What are these 2 的s doing here? I have 2 的s in my text which are confusing. 


"可以明确的是实习生与企业间不是劳动关系，。。。“
"我九月份进的这家公司，老板说前面几个月是作为实习期的。“


In 1. I think '的‘ nominalizes, but I'm not sure what it nominalizes. Maybe there is a ‘所’ understood and unspoken, '(所）可以明确的‘ = （that which） （we) can be sure of'。I don't really think '明确的‘ or '可以明确的‘ are nouns, neither in English nor in Chinese.

In 2. I can't see what 的 does. Nothing? Or is there a missing 是 ‘我是九月份进的这家公司’？Or is it just for the rhythm of speech? Or can I rewrite as '这家我九月份进的公司，‘? That doesn't seem right! Maybe '这家我九月份进的公司的老板说，‘
