In addition, we have made such other examinations of law and fact as we have considered necessary in order to form a basis of the opinions hereinafter expressed. In connection with such investigation, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, and the conformity to originals of all documents submitted to us as photocopies or conformed copies. We have relied as to matters of fact upon declarations and certificates of officers of the Company.
