Generally, all controlled participants in a CSA taking options on publicly traded stock into account under paragraph (d)(3)(ii), (d)(3)(iii)(A), or (d)(3)(iii)(B) of this section must use that same method of identification, measurement and timing for all options on publicly traded stock with respect to that CSA. Controlled participants may change their method only with the consent of the Commissioner and only with respect to stock options granted during taxable years subsequent to the taxable year in which the Commissioner’s consent is obtained. All controlled participants in the CSA must join in requests for the Commissioner’s consent under this paragraph (d)(3)(iii)(C). Thus, for example, if the controlled participants make the election described in paragraph (d)(3)(iii)(B) of this section upon the formation of the CSA, the election may be revoked only with the consent of the Commissioner, and the consent will apply only to stock options granted in taxable years subsequent to the taxable year in which consent is obtained. Similarly, if controlled participants already have granted stock options that have been or will be taken into account under the general rule of paragraph (d)(3)(iii)(A) of this section, then except in cases specified in the last sentence of paragraph (d)(3)(iii)(B)(4) of this section, the controlled participants may make the election described in paragraph (d)(3)(iii)(B) of this section only with the consent of the Commissioner, and the consent will apply only to stock options granted in taxable years subsequent to the taxable year in which consent is obtained ...

The election described in this paragraph (d)(3)(iii)(B) is made by an explicit reference to the election in the written contract required by paragraph (k)(1) of this section or in a written amendment to the CSA entered into with the consent of the Commissioner pursuant to paragraph (d)(3)(iii)(C) of this section. In the case of a CSA in existence on August 26, 2003, the election by written amendment to the CSA may be made without the consent of the Commissioner if such amendment is entered into not later than the latest due date (with regard to extensions) of a federal income tax return of any controlled participant for the first taxable year beginning after August 26, 2003 ...

For purposes of this paragraph (d)(3)(iii)(B), a financial statement prepared in accordance with a comprehensive body of generally accepted accounting principles other than United States generally accepted accounting principles is considered to be prepared in accordance with United States generally accepted accounting principles provided that either – (i) The fair value of the stock options under consideration is reflected in the reconciliation between such other accounting principles and United States generally accepted accounting principles required to be incorporated into the financial statement by the securities laws governing companies whose stock is regularly traded on United States securities markets; or (ii) In the absence of a reconciliation between such other accounting principles and United States generally accepted accounting principles that reflects the fair value of the stock options under consideration, such other accounting principles require that the fair value of the stock options under consideration be reflected as a charge against income in audited financial statements or disclosed in footnotes to such statements ...

With respect to stock-based compensation in the form of options on publicly traded stock, the controlled participants in a CSA may elect to take into account all IDCs attributable to those stock options in the same amount, and as of the same time, as the fair value of the stock options reflected as a charge against income in audited financial statements or disclosed in footnotes to such financial statements, provided that such statements are prepared in accordance with United States generally accepted accounting principles by or on behalf of the company issuing the publicly traded stock ...

Accordingly, the amount of the deduction that would be allowable (or treated as allowable under this paragraph (d)(3)(iii)(A)) to the controlled participant upon exercise of the stock-based compensation must be taken into account as an IDC as of the date of the expiration or termination of the CSA ...

Solely for purposes of this paragraph (d)(3)(iii)(A), if the repricing or other modification of a stock option is determined, under paragraph (d)(3)(ii) of this section, to constitute the grant of a new stock option not identified with, or reasonably allocable to, the IDA, the stock option that is repriced or otherwise modified will be treated as being exercised immediately before the modification, provided that the stock option is then exercisable and the fair market value of the underlying stock then exceeds the price at which the stock option is exercisable. Accordingly, the amount of the deduction that would be allowable (or treated as allowable under this paragraph (d)(3)(iii)(A)) to the controlled participant upon exercise of the stock option immediately before the modification must be taken into account as an IDC as of the date of the modification ...

...

The determination of whether stock-based compensation is directly identified with, or reasonably allocable to, the IDA is made as of the date that the stock-based compensation is granted. Accordingly, all stock-based compensation that is granted during the term of the CSA and, at date of grant, is directly identified with, or reasonably allocable to, the IDA is included as an IDC under paragraph (d)(1) of this section. In the case of a repricing or other modification of a stock option, the determination of whether the repricing or other modification constitutes the grant of a new stock option for purposes of this paragraph (d)(3)(ii) will be made in accordance with the rules of section 424(h) and related regulations ...

As used in this section, the term stock-based compensation means any compensation provided by a controlled participant to an employee or independent contractor in the form of equity instruments, options to acquire stock (stock options), or rights with respect to (or determined by reference to) equity instruments or stock options, including but not limited to property to which section 83 applies and stock options to which section 421 applies, regardless of whether ultimately settled in the form of cash, stock, or other property ...

On July 27, 2015 the United States Tax Court issued its ruling regarding the petition filed by Altera Corporation and its subsidiaries against the Commissioner of Internal Revenue. The court found in favor of Altera, and concluded that on an arm’s length basis employee profit sharing should not be included in compensation between related parties under Qualified Cost Sharing Agreements. The case was appealed by the Commissioner of Internal Revenueon February 23, 2016. In the appeal the Commissioner argues that the Tax Court erred as a matter of law in holding that the 2003 cost-sharing amendments are invalid to the extent they require the sharing of stock based compensation costs. In July 2018 the Court of Appeal reversed the decision from the Tax Court and found in favor of the Commissioner. And ...
