While we have developed contingency plans to flex and shift production in the case of temporary shutdowns or closures of our manufacturing facilities, we may be unable to shift all impacted operations to alternatives sites. If we are unable to generate sufficient cash flow to meet our debt service obligations, we will have to pursue one or more alternatives, such as reducing or delaying capital or other expenditures, refinancing debt, selling assets, or raising equity capital. Non-GAAP financial measures have limitations as analytical tools and should not be considered in isolation from, or solely as alternatives to, financial measures prepared in accordance with GAAP.

We may also experience increased competition from companies that offer products based on alternative technologies and processes that may cause us to lose customers. Based on the current funded status of the plan, our pension asset investment allocation guidelines are to invest 60% to 70% in fixed income securities, 30% to 40% in equity securities and 0% to 10% in alternative investments and cash. These alternative investments may include funds of multiple asset investment strategies and funds of hedge funds.

ColorMatrix™ Lactra™ SX additive provides high-performance light-blocking technology that enables a recyclable alternative to long-life dairy packaging. If we are unable to generate sufficient cash flow to meet our debt service obligations, we will have to pursue one or more alternatives, such as reducing or delaying capital or other expenditures, refinancing debt, selling assets, or raising equity capital. Depending upon the results of future testing, the ultimate remediation alternatives undertaken, changes in regulations, new information, newly discovered conditions and other factors, it is reasonably possible that we could incur additional costs in excess of the amount accrued.

We may also experience increased competition from companies that offer products based on alternative technologies and processes that may be more competitive or better in price or performance, causing us to lose customers. Based on the current funded status of the plan, our pension asset investment allocation guidelines are to invest 70% to 80% in fixed income securities, 20% to 30% in equity securities and 0% to 10% in alternative investments and cash. These alternative investments may include funds of multiple asset investment strategies and funds of hedge funds.
