Contingencies Liabilities for loss contingencies arising from claims, assessments, litigation, fines, penalties and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. At each reporting date the Company evaluates whether or not a potential loss amount or a potential loss range is probable and reasonably estimable under the provisions of the authoritative guidelines that address accounting for contingencies. The Company expenses costs as incurred in relation to such legal proceedings. The Company is not currently involved in any legal matters arising in the normal course of business. Under the terms of their respective employment agreements, each of the executive officers is eligible to receive severance payments and benefits upon a termination without cause or due to permanent disability, or upon resignation for good reason, contingent upon the named executive officers continued performance for the Company.
