Reliant FORM 10-K Determining whether an arrangement contains a lease, Stock-based compensation

SOP 97-2. The adoption of EITF 00-21 and EITF 03-5 did not have a material impact on Nortel Networks S.A. results of operations and financial condition.

(f)Amendment of SFAS 133 on derivative instruments and hedging activities

In April 2003, the FASB issued SFAS No. 149, “Amendment of SFAS No. 133 on Derivative Instruments and Hedging Activities” (“SFAS 149”). SFAS 149 amends and clarifies accounting for derivative instruments, including certain derivative instruments embedded in other contracts and hedging activities under SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities” (“SFAS 133”). In particular, SFAS 149: clarifies under what circumstances a contract with an initial net investment meets the characteristic of a derivative as discussed in SFAS 133; clarifies when a derivative contains a financing component; amends the definition of an “underlying” to conform it to the language used in FIN 45; and amends certain other existing pronouncements. SFAS 149 is effective for contracts entered into or modified after June 30, 2003, except as stated below, and for hedging relationships designated after June 30, 2003.

The provisions of SFAS 149 that relate to guidance in SFAS 133 that have been effective for fiscal quarters which began prior to June 15, 2003 continue to be applied in accordance with their respective effective dates. In addition, certain provisions relating to forward purchases or sales of when-issued securities or other securities that do not yet exist are applied to both existing contracts as well as new contracts entered into after June 30, 2003.

Effective July 1, 2003, Nortel Networks S.A. applied the requirements of SFAS 149 on a prospective basis to contracts entered into or modified after June 30, 2003. The adoption of SFAS 149 did not have a material impact on Nortel Networks S.A. results of operations and financial condition.

(g)Determining whether an arrangement contains a lease

In May 2003, the EITF reached a consensus on Issue No. 01-8, “Determining Whether an Arrangement Contains a Lease” (“EITF 01-8”). EITF 01-8 provides guidance on how to determine whether an arrangement contains a lease that is within the scope of FASB Statement No. 13, “Accounting for Leases.” The guidance in EITF 01-8 is based on whether the arrangement conveys to the purchaser (or the lessee) the right to use or control the use of a specific asset, and is effective for Nortel Networks S.A. for arrangements entered into or modified after June 30, 2003. The impact of EITF 01-8 on Nortel Networks S.A. future results of operations and financial condition will depend on the terms contained in contracts signed or contracts amended in the future.

(h)Stock-based compensation

In December 2002, the FASB issued SFAS 148, which amended the transitional provisions of SFAS 123 for companies electing to recognize employee stock-based compensation using the fair value based method. Effective January 1, 2003, Nortel Networks S.A. elected to expense employee stock-based compensation using the fair value based method prospectively for all awards granted, modified, or settled on or after January 1, 2003 (see note 2(s)).

(i)Accounting for goodwill and other intangible assets

In June 2001, the FASB issued SFAS No. 142, “Goodwill and Other Intangible Assets” (“SFAS 142”), effective for fiscal years beginning after December 15, 2001. SFAS 142 changed the accounting for goodwill from an amortization method to an impairment-only approach. Thus, amortization of goodwill, including goodwill recorded in past business combinations and amortization of intangibles with an indefinite life, ceased upon adoption of SFAS 142. For any acquisitions completed after

June 30, 2001, goodwill and intangible assets with an indefinite life are not amortized. Nortel Networks S.A. adopted the provisions of SFAS 142 effective January 1, 2002.
