A bond provides for the interest rate to be reset every 49 days through an auction by a remarketing agent. The reset of the interest rate occurs by operation of the terms of the bond and is not an alteration described in paragraph (c)(2) of this section. Thus, the reset of the interest rate is not a modification.
The original terms of a bond provide that the bond must be secured by a certain type of collateral having a specified value. The terms also require the issuer to substitute collateral if the value of the original collateral decreases. Any substitution of collateral that is required to maintain the value of the collateral occurs by operation of the terms of the bond and is not an alteration described in paragraph (c)(2) of this section. Thus, such a substitution of collateral is not a modification.
The original terms of a bond provide that the interest rate is 9 percent. The terms also provide that, if the issuer files an effective registration statement covering the bonds with the Securities and Exchange Commission, the interest rate will decrease to 8 percent. If the issuer registers the bond, the resulting decrease in the interest rate occurs by operation of the terms of the bond and is not an alteration described in paragraph (c)(2) of this section. Thus, such a decrease in the interest rate is not a modification.
Under the original terms of a bond issued by a corporation, an acquirer of substantially all of the corporation's assets may assume the corporation's obligations under the bond. Substantially all of the corporation's assets are acquired by another corporation and the acquiring corporation becomes the new obligor on the bond. Under paragraph (c)(2)(i) of this section, the substitution of a new obligor, even though it occurs by operation of the terms of the bond, is a modification.
(i) A corporation issues a 30-year, recourse bond. Under the terms of the bond, the corporation may secure a release of the financial and restrictive covenants by placing in trust government securities as collateral that will provide interest and principal payments sufficient to satisfy all scheduled payments on the bond. The corporation remains obligated for all payments, including the contribution of additional securities to the trust if necessary to provide sufficient amounts to satisfy the payment obligations. Under paragraph (c)(3) of this section, the option to defease the bond is a unilateral option.
(ii) The alterations occur by operation of the terms of the debt instrument and are not described in paragraph (c)(2) of this section. Thus, such a release of the covenants is not a modification.
Under the terms of a recourse bond, the issuer may secure a release of the financial and restrictive covenants by placing in trust government securities that will provide interest and principal payments sufficient to satisfy all scheduled payments on the bond. Upon the creation of the trust, the issuer is released from any recourse liability on the bond and has no obligation to contribute additional securities to the trust if the trust funds are not sufficient to satisfy the scheduled payments on the bond. The release of the issuer is an alteration described in paragraph (c)(2)(i) of this section, and thus is a modification.
(i) A financial institution holds a residential mortgage. Under the original terms of the mortgage, the financial institution has an option to decrease the interest rate. The financial institution anticipates that, if market interest rates decline, it may exercise this option in lieu of the mortgagor refinancing with another lender.
(ii) The financial institution exercises the option to reduce the interest rate. The exercise of the option results in a reduction in scheduled payments and is an alteration described in paragraph (c)(2)(iii) of this section. Thus, the change in interest rate is a modification.
(i) The original terms of a mortgage provide for a variable interest rate, reset annually based on the value of an objective index. Under the terms of the mortgage, the mortgagor may, upon the payment of a fee equal to a specified percentage of the outstanding principal amount of the mortgage, convert to a fixed rate of interest as determined based on the value of a second objective index. The exercise of the option does not require the consent or approval of any person or create a right of the holder to alter the terms of, or to put, the instrument.
(ii) Because the required consideration to exercise the option is a specified amount fixed on the issue date, the exercise of the option is unilateral as defined in paragraph (c)(3) of this section. The conversion to a fixed rate of interest is not an alteration described in paragraph (c)(2) of this section. Thus, the change in the type of interest rate occurs by operation of the terms of the instrument and is not a modification.
(i) A corporation issues an 8-year note to a bank in exchange for cash. Under the terms of the note, the bank has the option to increase the rate of interest by a specified amount if certain covenants in the note are breached. The bank's right to increase the interest rate is a unilateral option as described in paragraph (c)(3) of this section.
(ii) A covenant in the note is breached. The bank exercises its option to increase the rate of interest. The increase in the rate of interest occurs by operation of the terms of the note and does not result in a deferral or a reduction in the scheduled payments or any other alteration described in paragraph (c)(2) of this section. Thus, the change in interest rate is not a modification.
(iii) Applicability date. This Example 9 applies to modifications occurring on or after July 6, 2011.
A corporation issues a 5-year note. Under the terms of the note, interest is payable annually at the rate of 10 percent. The corporation, however, has an option to defer any payment of interest until maturity. For any payments that are deferred, interest will compound at a rate of 12 percent. The exercise of the option, which results in the deferral of payments, does not result from the exercise of an option by the holder. The exercise of the option occurs by operation of the terms of the debt instrument and is not a modification.
(i) A corporation issues a 10-year note to a bank in exchange for cash. Interest on the note is payable semi-annually. Under the terms of the note, the bank may grant the corporation the right to defer all or part of the interest payments. For any payments that are deferred, interest will compound at a rate 150 basis points greater than the stated rate of interest.
(ii) The corporation encounters financial difficulty and is unable to satisfy its obligations under the note. The bank exercises its option under the note and grants the corporation the right to defer payments. The exercise of the option results in a right of the corporation to defer scheduled payments and, under paragraph (c)(3)(i) of this section, is not a unilateral option. Thus, the alteration is described in paragraph (c)(2)(iii) of this section and is a modification.
The original terms of a bond include a provision that the issuer may extend the maturity of the bond with the consent of the holder. Because any extension pursuant to this term requires the consent of both parties, such an extension does not occur by the exercise of a unilateral option (as defined in paragraph (c)(3) of this section) and is a modification.
Under the terms of a bond, if the issuer fails to make a scheduled payment, the full principal amount of the bond is due and payable immediately. Following the issuer's failure to make a scheduled payment, the holder temporarily waives its right to receive the full principal for a period ending one year from the date of the issuer's default to allow the issuer to obtain additional financial resources. Under paragraph (c)(4)(ii) of this section, the temporary waiver in this situation is not a modification. The result would be the same if the terms provided the holder with the right to demand the full principal amount upon the failure of the issuer to make a scheduled payment and, upon such a failure, the holder exercised that right and then waived the right to receive the payment for one year.
(i) Under the terms of a 30-year, fixed-rate bond, the issuer can call the bond for 102 percent of par at the end of ten years or for 101 percent of par at the end of 20 years. At the end of the eighth year, the holder of the bond pays the issuer to waive the issuer's right to call the bond at the end of the tenth year. On the date of the modification, the issuer's credit quality is approximately the same as when the bond was issued, but market rates of interest have declined from that date.
(ii) The holder's payment to the issuer changes the yield on the bond. Whether the change in yield is a significant modification depends on whether the yield on the modified bond varies from the yield on the original bond by more than the change in yield as described in paragraph (e)(2)(ii) of this section.
(iii) If the change in yield is not a significant modification, the elimination of the issuer's call right must also be tested for significance. Because the specific rules of paragraphs (e)(2) through (e)(6) of this section do not address this modification, the significance of the modification must be determined under the general rule of paragraph (e)(1) of this section.
(iv) Applicability date. This Example 1 applies to modifications occurring on or after July 6, 2011.
(i) A zero-coupon bond has an original maturity of ten years. At the end of the fifth year, the parties agree to extend the maturity for a period of two years without increasing the stated redemption price at maturity (i.e., there are no additional payments due between the original and extended maturity dates, and the amount due at the extended maturity date is equal to the amount due at the original maturity date).
(ii) The deferral of the scheduled payment at maturity is tested under paragraph (e)(3) of this section. The safe-harbor period under paragraph (e)(3)(ii) of this section starts with the date the payment that is being deferred is due. For this modification, the safe-harbor period starts on the original maturity date, and ends five years from this date. All payments deferred within this period are unconditionally payable before the end of the safe-harbor period. Thus, the deferral of the payment at maturity for a period of two years is not a material deferral under the safe-harbor rule of paragraph (e)(3)(ii) of this section and thus is not a significant modification.
(iii) Even though the extension of maturity is not a significant modification under paragraph (e)(3)(ii) of this section, the modification also decreases the yield of the bond. The change in yield must be tested under paragraph (e)(2) of this section.
(i) A debt instrument issued at par has an original maturity of ten years and provides for the payment of $100,000 at maturity with interest payments at the rate of 10 percent payable at the end of each year. At the end of the fifth year, and after the annual payment of interest, the issuer and holder agree to reduce the amount payable at maturity to $80,000. The annual interest rate remains at 10 percent but is payable on the reduced principal.
(ii) In applying the change in yield rule of paragraph (e)(2) of this section, the yield of the instrument after the modification (measured from the date that the parties agree to the modification to its final maturity date) is computed using the adjusted issue price of $100,000. With four annual payments of $8,000, and a payment of $88,000 at maturity, the yield on the instrument after the modification for purposes of determining if there has been a significant modification under paragraph (e)(2)(i) of this section is 4.332 percent. Thus, the reduction in principal is a significant modification.
(i) A 20-year debt instrument issued at par provides for the payment of $100,000 at maturity with annual interest payments at the rate of 10 percent. At the beginning of the eleventh year, the issuer and holder agree to defer all remaining interest payments until maturity with compounding. The yield of the modified instrument remains at 10 percent.
(ii) The safe-harbor period of paragraph (e)(3)(ii) of this section begins at the end of the eleventh year, when the interest payment for that year is deferred, and ends at the end of the sixteenth year. However, the payments deferred during this period are not unconditionally payable by the end of that 5-year period. Thus, the deferral of the interest payments is not within the safe-harbor period.
(iii) This modification materially defers the payments due under the instrument and is a significant modification under paragraph (e)(3)(i) of this section.
(i) A recourse debt instrument with a 9 percent annual yield is secured by an office building. Under the terms of the instrument, a purchaser of the building may assume the debt and be substituted for the original obligor if the purchaser is equally or more creditworthy than the original obligor and if the interest rate on the instrument is increased by one-half percent (50 basis points). The building is sold, the purchaser assumes the debt, and the interest rate increases by 50 basis points.
(ii) If the purchaser's acquisition of the building does not satisfy the requirements of paragraph (e)(4)(i)(B) or paragraph (e)(4)(i)(C) of this section, the substitution of the purchaser as the obligor is a significant modification under paragraph (e)(4)(i)(A) of this section.
(iii) If the purchaser acquires substantially all of the assets of the original obligor, the assumption of the debt instrument will not result in a significant modification if there is not a change in payment expectations and the assumption does not result in a significant alteration.
(iv) The change in the interest rate, if tested under the rules of paragraph (e)(2) of this section, would result in a significant modification. The change in interest rate that results from the transaction is a significant alteration. Thus, the transaction does not meet the requirements of paragraph (e)(4)(i)(C) of this section and is a significant modification under paragraph (e)(4)(i)(A) of this section.
(v) Applicability date. This Example 5 applies to modifications occurring on or after July 6, 2011.
(i) A recourse debt instrument is secured by a building. In connection with the sale of the building, the purchaser of the building assumes the debt and is substituted as the new obligor on the debt instrument. The purchaser does not acquire substantially all of the assets of the original obligor.
(ii) The transaction does not satisfy any of the exceptions set forth in paragraph (e)(4)(i) (B) or (C) of this section. Thus, the substitution of the purchaser as the obligor is a significant modification under paragraph (e)(4)(i)(A) of this section.
(iii) Section 1274(c)(4), however, provides that if a debt instrument is assumed in connection with the sale or exchange of property, the assumption is not taken into account in determining if section 1274 applies to the debt instrument unless the terms and conditions of the debt instrument are modified in connection with the sale or exchange. Because the purchaser assumed the debt instrument in connection with the sale of property and the debt instrument was not otherwise modified, the debt instrument is not retested to determine whether it provides for adequate stated interest.
(i) The interest rate on a 30-year debt instrument issued by a corporation provides for a variable rate of interest that is reset annually on June 1st based on an objective index.
(ii) In the tenth year, the issuer merges (in a transaction to which section 381(a) applies) into another corporation that becomes the new obligor on the debt instrument. The merger occurs on June 1st, at which time the interest rate is also reset by operation of the terms of the instrument. The new interest rate varies from the previous interest rate by more than the greater of 25 basis points and 5 percent of the annual yield of the unmodified instrument. The substitution of a new obligor does not result in a change in payment expectations.
(iii) The substitution of the new obligor occurs in a section 381(a) transaction and does not result in a change in payment expectations. Although the interest rate changed by more than the greater of 25 basis points and 5 percent of the annual yield of the unmodified instrument, this alteration did not occur as a result of the transaction and is not a significant alteration under paragraph (e)(4)(i)(E) of this section. Thus, the substitution meets the requirements of paragraph (e)(4)(i)(B) of this section and is not a significant modification.
(i) Under the terms of a recourse debt instrument, the issuer's obligations are secured by a letter of credit from a specified bank. The debt instrument does not contain any provision allowing a substitution of a letter of credit from a different bank. The specified bank, however, encounters financial difficulty. The issuer and holder agree that the issuer will substitute a letter of credit from another bank.
(ii) Under paragraph (e)(4)(iv)(A) of this section, the substitution of a different credit enhancement contract is not a significant modification of a recourse debt instrument unless the substitution results in a change in payment expectations. While the substitution of a new letter of credit by a different bank does not itself result in a change in payment expectations, such a substitution may result in a change in payment expectations under certain circumstances (for example, if the obligor's capacity to meet payment obligations is dependent on the letter of credit and the substitution substantially enhances that capacity from primarily speculative to adequate).
(iii) Applicability date. This Example 8 applies to modifications occurring on or after July 6, 2011.
A parcel of land and its improvements, a shopping center, secure a nonrecourse debt instrument. The obligor expands the shopping center with the construction of an additional building on the same parcel of land. After the construction, the improvements that secure the nonrecourse debt include the new building. The building is an improvement to the property securing the nonrecourse debt instrument and its inclusion in the collateral securing the debt is not a significant modification under paragraph (e)(4)(iv)(B) of this section.
