(Level 1) and the lowest priority to unobservable inputs (Level 3).
The three levels of the fair value hierarchy are described below: ?
Level 1—Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.  ?
Level 2—Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (e. g. , interest rates); and inputs that are derived principally from or corroborated by observable market data by correlation or other means.  ?
Level 3—Inputs that are both significant to the fair value measurement and unobservable.
The carrying values and fair values of Arconic’s financial instruments were as follows:
## Table 0 ##
The following methods were used to estimate the fair values of financial instruments: Cash and cash equivalents, Restricted cash, Short-term borrowings, and Commercial paper.
The carrying amounts approximate fair value because of the short maturity of the instruments.
The fair value amounts for Cash and cash equivalents, Restricted cash, and Commercial paper were classified in Level 1, and Short-term borrowings were classified in Level 2.
Derivatives.
The fair value of derivative contracts classified as Level 1 was based on identical unrestricted assets and liabilities.
The fair value of derivative contracts classified as Level 2 was based on inputs other than quoted prices that are observable for the asset or liability (e. g.  interest rates).
Noncurrent receivables.
The fair value of noncurrent receivables was based on anticipated cash flows, which approximates carrying value, and was classified in Level 2 of the fair value hierarchy.
Available-for-sale securities.
The fair value of such securities was based on quoted market prices.
These financial instruments consist of exchange-traded fixed income and equity securities, which are carried at fair value and were classified in Level 1 of the fair value hierarchy.

In July 2018, the Company announced it had signed a new long-term contract with Boeing to supply aluminum sheet and plate for all models produced by Boeing Commercial Airplanes.
The multiyear contract, which extends and adds to the Companies’ 2014 contract, is the largest to date and captures growth in the build rate increases of the Boeing 737 program.
On October 31, 2018, the Company sold its Texarkana, Texas rolling mill and cast house to Ta Chen International, Inc.  for $302 million in cash, subject to post-closing adjustments, plus additional contingent consideration of up to $50 million.
The contingent consideration relates to the achievement of various milestones within 36 months of the transaction closing date associated with operationalizing the rolling mill equipment.
The Texarkana rolling mill facility had previously been idle since late 2009.
In early 2016, the Company restarted the Texarkana cast house to meet demand for aluminum slab.
As part of the agreement, the Company will continue to produce aluminum slab at the facility for a period of 18 months through a lease back of the cast house building and equipment, after which time, Ta Chen will perform toll processing of metal for the Company for a period of six months.
The Company will supply Ta Chen with cold-rolled aluminum coil during this 24-month period.
In February 2019, the Company announced an investment of approximately $100 million to expand its hot mill capability and add downstream equipment capabilities to manufacture industrial and automotive aluminum products in its Tennessee Operations facility near Knoxville, Tennessee.
The project, which is expected to create 70 new jobs, is already underway and is expected to be complete by the fourth quarter of 2020.
