Invesco CurrencyShares^® British Pound Sterling Trust

Notes to Unaudited Financial Statements

September 30, 2019

Note 1 – Background

On September 28, 2017, Guggenheim Capital, LLC (“Guggenheim”) and Invesco Ltd. entered into a Transaction Agreement (the “Transaction Agreement”), pursuant to which Guggenheim agreed to transfer all of the membership interests of Guggenheim Specialized Products, LLC (the “Sponsor”) to Invesco Capital Management LLC (“Invesco Capital Management”).

The Transaction Agreement was consummated on April 6, 2018 (the “Closing”) and immediately following the Closing, Invesco Capital Management changed the name of the Sponsor to Invesco Specialized Products, LLC.

On January 9, 2019, the Sponsor changed the Trust’s fiscal year from the period beginning on November 1 and ending on October 31 to the period beginning on January 1 and ending on December 31. Unless otherwise noted, all references to “years” in this report refer to the twelve-month fiscal year, which prior to November 1, 2018 ended on October 31 and beginning after December 31, 2018 ends on December 31 of each year.

Note 2 – Organization

The Invesco CurrencyShares^® British Pound Sterling Trust (the “Trust”) was formed under the laws of the State of New York on June 8, 2006 when the Sponsor deposited 100 British Pounds Sterling in the Trust’s primary deposit account held by JPMorgan Chase Bank, N.A., London Branch (the “Depository”). The Sponsor is a Delaware limited liability company whose sole member is Invesco Capital Management.

The investment objective of the Trust is for the Trust’s shares (the “Shares”) to reflect the price in U.S. Dollars (“USD”) of the British Pound Sterling plus accrued interest, if any, less the Trust’s expenses and liabilities. The Shares are intended to provide investors with a simple, cost-effective means of gaining investment benefits similar to those of holding British Pounds Sterling. The Trust’s assets primarily consist of British Pounds Sterling on demand deposit in two deposit accounts maintained by the Depository: a primary deposit account which may earn interest and a secondary deposit account which does not earn interest. The secondary deposit account is used to account for any interest that may be received and paid out on creations and redemptions of blocks of 50,000 Shares (“Baskets”). The secondary account is also used to account for interest earned, if any, on the primary deposit account, pay Trust expenses and distribute any excess interest to holders of Shares (“Shareholders”) on a monthly basis.

This Quarterly Report (the “Report”) covers the three and nine months ended September 30, 2019 and 2018. The accompanying unaudited financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions for Form 10-Q and the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”). In the opinion of management, all material adjustments, consisting only of normal recurring adjustments, considered necessary for a fair statement of the interim period financial statements have been made. Interim period results are not necessarily indicative of results for a full-year period. These financial statements and the notes thereto should be read in conjunction with the Trust’s financial statements included in the Form 10-K transition report as filed on March 11, 2019.

Note 3 – Summary of Significant Accounting Policies

A. Basis of Presentation

The financial statements of the Trust have been prepared using U.S. GAAP.

B. Accounting Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates by a significant amount. In addition, the Trust monitors for material events or transactions that may occur or become known after the period-end date and before the date the financial statements are issued.

8

C. Foreign Currency Translation

For Net Asset Value (“NAV”) calculation purposes, British Pound Sterling deposits (cash) are translated at the Closing Spot Rate, which is the British Pound Sterling/USD exchange rate as determined and published by The WM Company at 4:00 PM (London time / London fixing) on each day that NYSE Arca, Inc. (“NYSE Arca”) is open for regular trading.

The Trust maintains its books and records in British Pounds Sterling. For financial statement reporting purposes, the U.S. Dollar is the reporting currency. As a result, the financial records of the Trust are translated from British Pounds Sterling to USD. The Closing Spot Rate on the last day of the period is used for translation in the statements of financial condition. The average Closing Spot Rate for the period is used for translation in the statements of comprehensive income and the statements of cash flows. The redeemable capital Shares are adjusted to redemption value and these adjustments are recorded against retained earnings.

D. Interest Income

Interest on the primary deposit account, if any, accrues daily as earned and is received or paid on a monthly basis. Any interest below zero for the period is reflected as interest expense on currency deposits. The Depository may change the rate at which interest accrues, including reducing the interest rate to zero or below zero, based upon changes in market conditions or based on the Depository’s liquidity needs.

E. Distributions  

To the extent that the interest earned by the Trust, if any, exceeds the sum of the Sponsor’s fee for the prior month plus other Trust expenses, if any, the Trust will distribute, as a dividend (herein referred to as dividends or distributions), the excess interest earned in British Pounds Sterling effective on the first business day of the subsequent month. The Trustee (as defined below) will direct that the excess British Pounds Sterling be converted into USD at the prevailing market rate and the Trustee will distribute the USD as promptly as practicable to Shareholders on a pro-rata basis (in accordance with the number of Shares that they own).

F. Routine Operational, Administrative and Other Ordinary Expenses

The Sponsor is responsible for all routine operational, administrative and other ordinary expenses of the Trust, including, but not limited to, the Trustee’s monthly fee, NYSE Arca listing fees, SEC registration fees, typical maintenance and transaction fees of the Depository, printing and mailing costs, audit fees and expenses, up to $100,000 per year in legal fees and expenses, and applicable license fees. The Trust does not reimburse the Sponsor for the routine operational, administrative and other ordinary expenses of the Trust. Accordingly, such expenses are not reflected in the Statements of Comprehensive Income of the Trust.

G. Non-Recurring Fees and Expenses

In certain exceptional cases the Trust will pay for some expenses in addition to the Sponsor’s fee. These exceptions include expenses not assumed by the Sponsor (i.e., expenses other than those identified in the preceding paragraph), expenses resulting from negative interest rates, taxes and governmental charges, expenses and costs of any extraordinary services performed by the Trustee or the Sponsor on behalf of the Trust or action taken by the Trustee or the Sponsor to protect the Trust or the interests of Shareholders, indemnification of the Sponsor under the Depositary Trust Agreement, audit fees and legal expenses in excess of $100,000 per year. The only expense of the Trust during the three and nine months ended September 30, 2019 was the Sponsor’s fee.

H. Federal Income Taxes

The Trust is treated as a “grantor trust” for federal income tax purposes and, therefore, no provision for federal income taxes is required. Interest, gains and losses are passed through to the Shareholders.

Shareholders generally will be treated, for U.S. federal income tax purposes, as if they directly owned a pro-rata share of the assets held in the Trust. Shareholders also will be treated as if they directly received their respective pro-rata portion of the Trust’s income, if any, and as if they directly incurred their respective pro-rata portion of the Trust’s expenses. The acquisition of Shares by a U.S. Shareholder as part of a creation of a Basket will not be a taxable event to the Shareholder.

The Sponsor’s fee accrues daily and is payable monthly. For U.S. federal income tax purposes, an accrual-basis U.S. Shareholder generally will be required to take into account as an expense its allocable portion of the USD-equivalent of the amount of the Sponsor’s fee that is accrued on each day, with such USD-equivalent being determined by the currency exchange rate that is in effect on the respective day. To the extent that the currency exchange rate on the date of payment of the accrued amount of the Sponsor’s fee differs from the currency exchange rate in effect on the day of accrual, the U.S. Shareholder will recognize a currency gain or loss for U.S. federal income tax purposes.

9

The Trust does not expect to generate taxable income except for interest income (if any) and gain (if any) upon the sale of British Pounds Sterling. A non-U.S. Shareholder generally will not be subject to U.S. federal income tax with respect to gain recognized upon the sale or other disposition of Shares, or upon the sale of British Pounds Sterling by the Trust, unless: (1) the non-U.S. Shareholder is an individual and is present in the United States for 183 days or more during the taxable year of the sale or other disposition, and the gain is treated as being from United States sources; or (2) the gain is effectively connected with the conduct by the non-U.S. Shareholder of a trade or business in the United States.

A non-U.S. Shareholder’s portion of any interest income earned by the Trust generally will not be subject to U.S. federal income tax unless the Shares owned by such non-U.S. Shareholder are effectively connected with the conduct by the non-U.S. Shareholder of a trade or business in the United States.

Note 4 – British Pound Sterling Deposits

British Pound Sterling principal deposits are held in a British Pound Sterling-denominated, interest-bearing demand account. The interest rate in effect as of September 30, 2019 was an annual nominal rate of 0.35%. For the nine months ended September 30, 2019, there were British Pound Sterling principal deposits of 72,735,398, British Pound Sterling principal redemptions of 53,342,369 and British Pound Sterling withdrawals (to pay expenses) of 38,129, resulting in an ending British Pound Sterling principal balance of 126,061,024. This equates to 155,344,945 USD. For the two months ended December 31, 2018, there were British Pound Sterling principal deposits of 19,401,440, British Pound Sterling principal redemptions of 29,102,021 and British Pound Sterling withdrawals (to pay expenses) of 9,701, resulting in an ending British Pound Sterling principal balance of 106,706,125. This equates to 135,900,899 USD.

Net interest, if any, associated with creation and redemption activity is held in a British Pound Sterling-denominated non-interest-bearing account, and any balance is distributed in full as part of the monthly income distributions, if any.

Note 5 – Concentration Risk

All of the Trust’s assets are British Pounds Sterling, which creates a concentration risk associated with fluctuations in the price of the British Pound Sterling. Accordingly, a decline in the British Pound Sterling to USD exchange rate will have an adverse effect on the value of the Shares. Factors that may have the effect of causing a decline in the price of the British Pound Sterling include national debt levels and trade deficits, domestic and foreign inflation rates, domestic and foreign interest rates, investment and trading activities of institutions and global or regional political, economic or financial events and situations. Substantial sales of British Pounds Sterling by the official sector (central banks, other governmental agencies and related institutions that buy, sell and hold British Pounds Sterling as part of their reserve assets) could adversely affect an investment in the Shares.

All of the Trust’s British Pounds Sterling are held by the Depository. Accordingly, a risk associated with the concentration of the Trust’s assets in accounts held by a single financial institution exists and increases the potential for loss by the Trust and the Trust’s beneficiaries in the event that the Depository becomes insolvent.

Note 6 – Service Providers and Related Party Agreements

The Trustee

The Bank of New York Mellon (the “Trustee”), a banking corporation with trust powers organized under the laws of the State of New York, serves as the Trustee. The Trustee is responsible for the day-to-day administration of the Trust, including keeping the Trust’s operational records.

The Sponsor

The Sponsor of the Trust generally oversees the performance of the Trustee and the Trust’s principal service providers. The Sponsor is Invesco Specialized Products, LLC, a Delaware limited liability company and a related party of the Trust.  The Trust pays the Sponsor a Sponsor’s fee, which accrues daily at an annual nominal rate of 0.40% of the British Pounds Sterling in the Trust (including all unpaid interest but excluding unpaid fees, each as accrued through the immediately preceding day) and is paid monthly.

Note 7 – Share Purchases and Redemptions

Shares are issued and redeemed continuously in Baskets in exchange for British Pounds Sterling. Individual investors cannot purchase or redeem Shares in direct transactions with the Trust. Only Authorized Participants (as defined below) may place orders to create and redeem Baskets. An Authorized Participant is a Depository Trust Company (“DTC”) participant that is a registered broker-dealer or other institution eligible to settle securities transactions through the book-entry facilities of the DTC and which has entered into a contractual arrangement with the Trust and the Sponsor governing, among other matters, the creation and redemption process. Authorized Participants may redeem their Shares at any time in Baskets.

10

Due to expected continuing creations and redemptions of Baskets and the two-day period for settlement of each creation or redemption, the Trust reflects Shares created as a receivable on the trade date. Shares redeemed are reflected as a liability on the trade date. Outstanding Shares are reflected at redemption value, which is the NAV per Share at the period end date. Adjustments to redeemable capital Shares at redemption value are recorded directly to redeemable capital shares and retained earnings.

The Trustee calculates the Trust’s NAV each business day. To calculate the NAV, the Trustee subtracts the Sponsor’s accrued fee through the previous day from the British Pounds Sterling held by the Trust (including all unpaid interest, if any, accrued through the preceding day) and calculates the value of the British Pounds Sterling in USD based upon the Closing Spot Rate. If, on a particular evaluation day, the Closing Spot Rate has not been determined and announced by 6:00 PM (London time), then the most recent Closing Spot Rate will be used to determine the NAV of the Trust unless the Trustee, in consultation with the Sponsor, determines that such price is inappropriate to use as the basis for the valuation. If the Trustee and the Sponsor determine that the most recent Closing Spot Rate is not an appropriate basis for valuation of the Trust’s British Pounds Sterling, they will determine an alternative basis for the valuation. The Trustee also determines the NAV per Share, which equals the NAV of the Trust, divided by the number of outstanding Shares. Shares deliverable under a purchase order are considered outstanding for purposes of determining NAV per Share; Shares deliverable under a redemption order are not considered outstanding for this purpose.

Note 8 – Commitments and Contingencies

The Trust’s organizational documents provide for the Trust to indemnify the Sponsor and any affiliate of the Sponsor that provides services to the Trust to the maximum extent permitted by applicable law, subject to certain exceptions for disqualifying conduct by the Sponsor or such an affiliate. The Trust’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Trust that have not yet occurred. Further, the Trust has not had prior claims or losses pursuant to these contracts. Accordingly, the Sponsor expects the risk of loss to be remote.

Overview/Introduction

The Invesco CurrencyShares^® British Pound Sterling Trust (the “Trust”) is a grantor trust that was formed on June 8, 2006. The Trust issues shares (the “Shares”) in blocks of 50,000 (a “Basket”) in exchange for deposits of British Pound Sterling and distributes British Pound Sterling in connection with the redemption of Baskets. The Shares commenced trading on the New York Stock Exchange under the ticker symbol “FXB” on June 26, 2006. The primary listing of the Shares was transferred to NYSE Arca on October 30, 2007.

The investment objective of the Trust is for the Shares to reflect the price in USD of the British Pound Sterling plus accrued interest, if any, less the expenses of the Trust’s operations. The Shares are intended to offer investors an opportunity to participate in the market for the British Pound Sterling through an investment in securities. The Shares are intended to provide institutional and retail investors with a simple, cost-effective means of gaining investment benefits similar to those of holding the British Pound Sterling. The Shares are bought and sold on NYSE Arca like any other exchange-listed security. The Shares are backed by the assets of the Trust, which does not hold or use derivative products. The Trust is a passive investment vehicle and does not have any officers, directors or employees. The Trust does not engage in any activities designed to obtain profit from, or ameliorate losses caused by, changes in the price of the British Pound Sterling. Investing in the Shares does not insulate the investor from certain risks, including price volatility. The value of the holdings of the Trust is reported on the Trust’s website, www.invesco.com/etfs, each business day.

Definition of Net Asset Value

The Trustee calculates, and the Sponsor publishes, the Trust’s Net Asset Value (“NAV”) each business day. To calculate the NAV, the Trustee adds to the amount of British Pounds Sterling in the Trust at the end of the preceding day accrued but unpaid interest, if any, British Pounds Sterling receivable under pending purchase orders and the value of other Trust assets, and subtracts the accrued but unpaid Sponsor’s fee, British Pounds Sterling payable under pending redemption orders and other Trust expenses and liabilities, if any. The NAV is expressed in USD based on the British Pound Sterling/USD exchange rate as determined by The WM Company at 4:00 PM (London time / London fixing) (the “Closing Spot Rate”) on each day that NYSE Arca is open for regular trading. If, on a particular evaluation day, the Closing Spot Rate has not been determined and announced by 6:00 PM (London time), then the most recent Closing Spot Rate is used to determine the NAV of the Trust unless the Trustee, in consultation with the Sponsor, determines that such price is inappropriate to use as the basis for the valuation.

The Trustee also determines the NAV per Share, which equals the NAV of the Trust divided by the number of outstanding Shares. The NAV of the Trust and the NAV per Share are published by the Sponsor on each day that NYSE Arca is open for regular trading and are posted on the Trust’s website, www.invesco.com/etfs.

Movements in the Price of the British Pound Sterling

The investment objective of the Trust is for the Shares to reflect the price in USD of the British Pound Sterling plus accrued interest, if any, less the expenses of the Trust’s operations. The Shares are intended to provide institutional and retail investors with a simple, cost-effective means of gaining investment benefits similar to those of holding British Pounds Sterling. Each outstanding Share represents a proportional interest in the British Pounds Sterling held by the Trust. The following chart provides recent trends on the price of the British Pound Sterling. The chart illustrates movements in the price of the British Pound Sterling in USD and is based on the Closing Spot Rate:

NAV per Share; Valuation of the British Pound Sterling

The following chart illustrates the movement in the price of the Shares based on (1) NAV per Share, (2) the “bid” and “ask” midpoint offered on NYSE Arca and (3) the Closing Spot Rate, expressed as a multiple of 100 British Pounds Sterling:

Liquidity

The Sponsor is not aware of any trends, demands, conditions or events that are reasonably likely to result in material changes to the Trust’s liquidity needs. The Trust’s Depository, JPMorgan Chase Bank, N.A., London Branch, maintains two deposit accounts for the Trust, a primary deposit account that may earn interest and a secondary deposit account that does not earn interest. Interest on the primary deposit account, if any, accrues daily and is paid monthly. The interest rate in effect as of September 30, 2019 was an annual nominal rate of 0.35%. The following chart provides the daily rate paid by the Depository since September 30, 2014:

In exchange for a fee, the Sponsor bears most of the expenses incurred by the Trust. As a result, the only ordinary expense of the Trust during the period covered by this report was the Sponsor’s fee. Each month the Depository deposits into the secondary deposit account accrued but unpaid interest, if any, and the Trustee withdraws British Pounds Sterling from the secondary deposit account to pay the accrued Sponsor’s fee for the previous month plus other Trust expenses, if any. When the interest deposited, if any, exceeds the sum of the Sponsor’s fee for the prior month plus other Trust expenses, if any, the Trustee converts the excess into USD at the prevailing market rate and distributes the USD as promptly as practicable to Shareholders on a pro-rata basis (in accordance with the number of Shares that they own). The Trust did not make any distributions during the quarter ended September 30, 2019.

Critical Accounting Policies

The financial statements and accompanying notes are prepared in accordance with U.S. GAAP. The preparation of these financial statements relies on estimates and assumptions that impact the Trust’s financial position and results of operations. These estimates and assumptions affect the Trust’s application of accounting policies. In addition, please refer to Note 3 to the financial statements of the Trust for further discussion of the Trust’s accounting policies and Item 7 – Management’s Discussions and Analysis of Financial Condition and Results of Operations – Critical Accounting Estimates in the Form 10-K transition report of the Trust for the period ended December 31, 2018.

Results of Operations

As of December 31, 2018, the number of British Pounds Sterling owned by the Trust was 106,706,125 resulting in a redeemable capital Share value of $135,895,374. During the nine months ended September 30, 2019, an additional 750,000 Shares were created in exchange for 72,735,398 British Pounds Sterling and 550,000 Shares were redeemed in exchange for 53,342,369 British Pounds Sterling. In addition, 38,129 British Pound Sterling were withdrawn to pay the portion of the Sponsor’s fee that exceeded the interest earned. As of September 30, 2019, the number of British Pounds Sterling owned by the Trust was 126,061,024, resulting in a redeemable capital Share value of $155,338,536.

An increase in the Trust’s redeemable capital Share value from $135,895,374 at December 31, 2018 to $155,338,536 at September 30, 2019 was primarily the result of an increase in the number of Shares outstanding from 1,100,000 at December 31, 2018

14

to 1,300,000 at September 30, 2019, but was partially offset by a decrease in the Closing Spot Rate from 1.2736 at December 31, 2018 to 1.2323 at September 30, 2019.

Interest income increased from $98,533 for the three months ended September 30, 2018 to $124,468 for the three months ended September 30, 2019, and increased from $181,512 for the nine months ended September 30, 2018 to $354,238 for the nine months ended September 30, 2019, attributable primarily to an increase in the annual nominal interest rate paid by the Depository, as set forth in the chart above.

The Sponsor’s fee accrues daily at an annual nominal rate of 0.40% of the British Pounds Sterling in the Trust. Due primarily to a decrease in the weighted-average British Pounds Sterling in the Trust, the Sponsor’s fee decreased from $158,523 for the three months ended September 30, 2018 to $142,248 for the three months ended September 30, 2019, and decreased from $530,421 for the nine months ended September 30, 2018 to $403,803 for the nine months ended September 30, 2019. The only expense of the Trust during the three and nine months ended September 30, 2019 was the Sponsor’s fee.

The Trust’s net comprehensive income (loss) for the three months ended September 30, 2019 was $(17,780) due to the Sponsor’s fee of $142,248 exceeding interest income of $124,468. The Trust’s net comprehensive income (loss) for the nine months ended September 30, 2019 was $(49,565) due to the Sponsor’s fee of $403,803 exceeding interest income of $354,238.

Cash dividends were not paid by the Trust during the nine months ended September 30, 2018 and the nine months ended September 30, 2019, as the Trust’s interest income did not exceed the Trust’s expenses during those periods.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Except as described above with respect to fluctuations in the British Pound Sterling/USD exchange rate and changes in the nominal annual interest rate paid by the Depository on British Pounds Sterling held by the Trust, the Trust is not subject to market risk. The Trust does not hold securities and does not invest in derivative products.

Item 4. Controls and Procedures

Under the supervision and with the participation of the management of the Sponsor, including Daniel Draper, its Principal Executive Officer, and Kelli Gallegos, its Principal Financial and Accounting Officer, Investment Pools, the Trust carried out an evaluation of the effectiveness of the design and operation of its disclosure controls and procedures (as defined in Rule 13a-15(e) or 15d-15(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this Quarterly Report, and, based upon that evaluation, Daniel Draper, the Principal Executive Officer of the Sponsor, and Kelli Gallegos, the Principal Financial and Accounting Officer, Investment Pools, of the Sponsor, concluded that the Trust's disclosure controls and procedures were effective to provide reasonable assurance that information the Trust is required to disclose in the reports that it files or submits with the Securities and Exchange Commission (the “SEC”) under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC's rules and forms, and to provide reasonable assurance that information required to be disclosed by the Trust in the reports that it files or submits under the Exchange Act is accumulated and communicated to management of the Sponsor, including its Principal Executive Officer and Principal Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There has been no change in internal control over financial reporting (as defined in the Rules 13a-15(f) and 15d-15(f) of the Exchange Act) that occurred during the Trust's quarter ended September 30, 2019 that has materially affected, or is reasonably likely to materially affect, the Trust's internal control over financial reporting.

Note 8 – Commitments and Contingencies

The Trust’s organizational documents provide for the Trust to indemnify the Sponsor and any affiliate of the Sponsor that provides services to the Trust to the maximum extent permitted by applicable law, subject to certain exceptions for disqualifying conduct by the Sponsor or such an affiliate. The Trust’s maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Trust that have not yet occurred. Further, the Trust has not had prior claims or losses pursuant to these contracts. Accordingly, the Sponsor expects the risk of loss to be remote.

For the two months ended December 31, 2018, there were British Pound Sterling principal deposits of 19,401,440, British Pound Sterling principal redemptions of 29,102,021 and British Pound Sterling withdrawals (to pay expenses) of 9,701, resulting in an ending British Pound Sterling principal balance of 106,706,125. This equates to 135,900,899 USD.

Net interest, if any, associated with creation and redemption activity is held in a British Pound Sterling-denominated non-interest-bearing account, and any balance is distributed in full as part of the monthly income distributions, if any.

Summary of Significant Accounting Policies (Policies)

9 Months Ended

Sep. 30, 2019

Accounting Policies [Abstract]

Basis of Presentation

A. Basis of Presentation

The financial statements of the Trust have been prepared using U.S. GAAP.

Accounting Estimates

B. Accounting Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates by a significant amount. In addition, the Trust monitors for material events or transactions that may occur or become known after the period-end date and before the date the financial statements are issued.

Foreign Currency Translation

C. Foreign Currency Translation

For Net Asset Value (“NAV”) calculation purposes, British Pound Sterling deposits (cash) are translated at the Closing Spot Rate, which is the British Pound Sterling/USD exchange rate as determined and published by The WM Company at 4:00 PM (London time / London fixing) on each day that NYSE Arca, Inc. (“NYSE Arca”) is open for regular trading.

The Trust maintains its books and records in British Pounds Sterling. For financial statement reporting purposes, the U.S. Dollar is the reporting currency. As a result, the financial records of the Trust are translated from British Pounds Sterling to USD. The Closing Spot Rate on the last day of the period is used for translation in the statements of financial condition. The average Closing Spot Rate for the period is used for translation in the statements of comprehensive income and the statements of cash flows. The redeemable capital Shares are adjusted to redemption value and these adjustments are recorded against retained earnings.

Interest Income

D. Interest Income

Interest on the primary deposit account, if any, accrues daily as earned and is received or paid on a monthly basis. Any interest below zero for the period is reflected as interest expense on currency deposits. The Depository may change the rate at which interest accrues, including reducing the interest rate to zero or below zero, based upon changes in market conditions or based on the Depository’s liquidity needs.

Distributions

E. Distributions  

To the extent that the interest earned by the Trust, if any, exceeds the sum of the Sponsor’s fee for the prior month plus other Trust expenses, if any, the Trust will distribute, as a dividend (herein referred to as dividends or distributions), the excess interest earned in British Pounds Sterling effective on the first business day of the subsequent month. The Trustee (as defined below) will direct that the excess British Pounds Sterling be converted into USD at the prevailing market rate and the Trustee will distribute the USD as promptly as practicable to Shareholders on a pro-rata basis (in accordance with the number of Shares that they own).

Routine Operational, Administrative and Other Ordinary Expenses

F. Routine Operational, Administrative and Other Ordinary Expenses

The Sponsor is responsible for all routine operational, administrative and other ordinary expenses of the Trust, including, but not limited to, the Trustee’s monthly fee, NYSE Arca listing fees, SEC registration fees, typical maintenance and transaction fees of the Depository, printing and mailing costs, audit fees and expenses, up to $100,000 per year in legal fees and expenses, and applicable license fees. The Trust does not reimburse the Sponsor for the routine operational, administrative and other ordinary expenses of the Trust. Accordingly, such expenses are not reflected in the Statements of Comprehensive Income of the Trust.

Non-Recurring Fees and Expenses

G. Non-Recurring Fees and Expenses

In certain exceptional cases the Trust will pay for some expenses in addition to the Sponsor’s fee. These exceptions include expenses not assumed by the Sponsor (i.e., expenses other than those identified in the preceding paragraph), expenses resulting from negative interest rates, taxes and governmental charges, expenses and costs of any extraordinary services performed by the Trustee or the Sponsor on behalf of the Trust or action taken by the Trustee or the Sponsor to protect the Trust or the interests of Shareholders, indemnification of the Sponsor under the Depositary Trust Agreement, audit fees and legal expenses in excess of $100,000 per year. The only expense of the Trust during the three and nine months ended September 30, 2019 was the Sponsor’s fee.

Federal Income Taxes

H. Federal Income Taxes

The Trust is treated as a “grantor trust” for federal income tax purposes and, therefore, no provision for federal income taxes is required. Interest, gains and losses are passed through to the Shareholders.

Shareholders generally will be treated, for U.S. federal income tax purposes, as if they directly owned a pro-rata share of the assets held in the Trust. Shareholders also will be treated as if they directly received their respective pro-rata portion of the Trust’s income, if any, and as if they directly incurred their respective pro-rata portion of the Trust’s expenses. The acquisition of Shares by a U.S. Shareholder as part of a creation of a Basket will not be a taxable event to the Shareholder.

The Sponsor’s fee accrues daily and is payable monthly. For U.S. federal income tax purposes, an accrual-basis U.S. Shareholder generally will be required to take into account as an expense its allocable portion of the USD-equivalent of the amount of the Sponsor’s fee that is accrued on each day, with such USD-equivalent being determined by the currency exchange rate that is in effect on the respective day. To the extent that the currency exchange rate on the date of payment of the accrued amount of the Sponsor’s fee differs from the currency exchange rate in effect on the day of accrual, the U.S. Shareholder will recognize a currency gain or loss for U.S. federal income tax purposes.

The Trust does not expect to generate taxable income except for interest income (if any) and gain (if any) upon the sale of British Pounds Sterling. A non-U.S. Shareholder generally will not be subject to U.S. federal income tax with respect to gain recognized upon the sale or other disposition of Shares, or upon the sale of British Pounds Sterling by the Trust, unless: (1) the non-U.S. Shareholder is an individual and is present in the United States for 183 days or more during the taxable year of the sale or other disposition, and the gain is treated as being from United States sources; or (2) the gain is effectively connected with the conduct by the non-U.S. Shareholder of a trade or business in the United States.

A non-U.S. Shareholder’s portion of any interest income earned by the Trust generally will not be subject to U.S. federal income tax unless the Shares owned by such non-U.S. Shareholder are effectively connected with the conduct by the non-U.S. Shareholder of a trade or business in the United States.

Concentration Risk

Sep. 30, 2019

Risks And Uncertainties [Abstract]

Concentration Risk

Note 5 – Concentration Risk

All of the Trust’s assets are British Pounds Sterling, which creates a concentration risk associated with fluctuations in the price of the British Pound Sterling. Accordingly, a decline in the British Pound Sterling to USD exchange rate will have an adverse effect on the value of the Shares. Factors that may have the effect of causing a decline in the price of the British Pound Sterling include national debt levels and trade deficits, domestic and foreign inflation rates, domestic and foreign interest rates, investment and trading activities of institutions and global or regional political, economic or financial events and situations. Substantial sales of British Pounds Sterling by the official sector (central banks, other governmental agencies and related institutions that buy, sell and hold British Pounds Sterling as part of their reserve assets) could adversely affect an investment in the Shares.

All of the Trust’s British Pounds Sterling are held by the Depository. Accordingly, a risk associated with the concentration of the Trust’s assets in accounts held by a single financial institution exists and increases the potential for loss by the Trust and the Trust’s beneficiaries in the event that the Depository becomes insolvent.

Share Purchases and Redemptions

9 Months Ended

Sep. 30, 2019

Federal Home Loan Banks [Abstract]

Share Purchases and Redemptions

Note 7 – Share Purchases and Redemptions

Shares are issued and redeemed continuously in Baskets in exchange for British Pounds Sterling. Individual investors cannot purchase or redeem Shares in direct transactions with the Trust. Only Authorized Participants (as defined below) may place orders to create and redeem Baskets. An Authorized Participant is a Depository Trust Company (“DTC”) participant that is a registered broker-dealer or other institution eligible to settle securities transactions through the book-entry facilities of the DTC and which has entered into a contractual arrangement with the Trust and the Sponsor governing, among other matters, the creation and redemption process. Authorized Participants may redeem their Shares at any time in Baskets.

Due to expected continuing creations and redemptions of Baskets and the two-day period for settlement of each creation or redemption, the Trust reflects Shares created as a receivable on the trade date. Shares redeemed are reflected as a liability on the trade date. Outstanding Shares are reflected at redemption value, which is the NAV per Share at the period end date. Adjustments to redeemable capital Shares at redemption value are recorded directly to redeemable capital shares and retained earnings.

The Trustee calculates the Trust’s NAV each business day. To calculate the NAV, the Trustee subtracts the Sponsor’s accrued fee through the previous day from the British Pounds Sterling held by the Trust (including all unpaid interest, if any, accrued through the preceding day) and calculates the value of the British Pounds Sterling in USD based upon the Closing Spot Rate. If, on a particular evaluation day, the Closing Spot Rate has not been determined and announced by 6:00 PM (London time), then the most recent Closing Spot Rate will be used to determine the NAV of the Trust unless the Trustee, in consultation with the Sponsor, determines that such price is inappropriate to use as the basis for the valuation. If the Trustee and the Sponsor determine that the most recent Closing Spot Rate is not an appropriate basis for valuation of the Trust’s British Pounds Sterling, they will determine an alternative basis for the valuation. The Trustee also determines the NAV per Share, which equals the NAV of the Trust, divided by the number of outstanding Shares. Shares deliverable under a purchase order are considered outstanding for purposes of determining NAV per Share; Shares deliverable under a redemption order are not considered outstanding for this purpose.

Note 2 – Organization

The Invesco CurrencyShares^® British Pound Sterling Trust (the “Trust”) was formed under the laws of the State of New York on June 8, 2006 when the Sponsor deposited 100 British Pounds Sterling in the Trust’s primary deposit account held by JPMorgan Chase Bank, N.A., London Branch (the “Depository”). The Sponsor is a Delaware limited liability company whose sole member is Invesco Capital Management.

The investment objective of the Trust is for the Trust’s shares (the “Shares”) to reflect the price in U.S. Dollars (“USD”) of the British Pound Sterling plus accrued interest, if any, less the Trust’s expenses and liabilities. The Shares are intended to provide investors with a simple, cost-effective means of gaining investment benefits similar to those of holding British Pounds Sterling. The Trust’s assets primarily consist of British Pounds Sterling on demand deposit in two deposit accounts maintained by the Depository: a primary deposit account which may earn interest and a secondary deposit account which does not earn interest. The secondary deposit account is used to account for any interest that may be received and paid out on creations and redemptions of blocks of 50,000 Shares (“Baskets”). The secondary account is also used to account for interest earned, if any, on the primary deposit account, pay Trust expenses and distribute any excess interest to holders of Shares (“Shareholders”) on a monthly basis.

This Quarterly Report (the “Report”) covers the three and nine months ended September 30, 2019 and 2018. The accompanying unaudited financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions for Form 10-Q and the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”). In the opinion of management, all material adjustments, consisting only of normal recurring adjustments, considered necessary for a fair statement of the interim period financial statements have been made. Interim period results are not necessarily indicative of results for a full-year period. These financial statements and the notes thereto should be read in conjunction with the Trust’s financial statements included in the Form 10-K transition report as filed on March 11, 2019.

Summary of Significant Accounting Policies

Note 3 – Summary of Significant Accounting Policies

A. Basis of Presentation

The financial statements of the Trust have been prepared using U.S. GAAP.

B. Accounting Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates by a significant amount. In addition, the Trust monitors for material events or transactions that may occur or become known after the period-end date and before the date the financial statements are issued.

C. Foreign Currency Translation

For Net Asset Value (“NAV”) calculation purposes, British Pound Sterling deposits (cash) are translated at the Closing Spot Rate, which is the British Pound Sterling/USD exchange rate as determined and published by The WM Company at 4:00 PM (London time / London fixing) on each day that NYSE Arca, Inc.

The Closing Spot Rate on the last day of the period is used for translation in the statements of financial condition. The average Closing Spot Rate for the period is used for translation in the statements of comprehensive income and the statements of cash flows. The redeemable capital Shares are adjusted to redemption value and these adjustments are recorded against retained earnings.

D. Interest Income

Interest on the primary deposit account, if any, accrues daily as earned and is received or paid on a monthly basis.

The Trust does not reimburse the Sponsor for the routine operational, administrative and other ordinary expenses of the Trust. Accordingly, such expenses are not reflected in the Statements of Comprehensive Income of the Trust.

G. Non-Recurring Fees and Expenses

In certain exceptional cases the Trust will pay for some expenses in addition to the Sponsor’s fee. These exceptions include expenses not assumed by the Sponsor (i.e., expenses other than those identified in the preceding paragraph), expenses resulting from negative interest rates, taxes and governmental charges, expenses and costs of any extraordinary services performed by the Trustee or the Sponsor on behalf of the Trust or action taken by the Trustee or the Sponsor to protect the Trust or the interests of Shareholders, indemnification of the Sponsor under the Depositary Trust Agreement, audit fees and legal expenses in excess of $100,000 per year. The only expense of the Trust during the three and nine months ended September 30, 2019 was the Sponsor’s fee.

H. Federal Income Taxes

The Trust is treated as a “grantor trust” for federal income tax purposes and, therefore, no provision for federal income taxes is required. Interest, gains and losses are passed through to the Shareholders.

The acquisition of Shares by a U.S. Shareholder as part of a creation of a Basket will not be a taxable event to the Shareholder.

The Sponsor’s fee accrues daily and is payable monthly. For U.S. federal income tax purposes, an accrual-basis U.S. Shareholder generally will be required to take into account as an expense its allocable portion of the USD-equivalent of the amount of the Sponsor’s fee that is accrued on each day, with such USD-equivalent being determined by the currency exchange rate that is in effect on the respective day. To the extent that the currency exchange rate on the date of payment of the accrued amount of the Sponsor’s fee differs from the currency exchange rate in effect on the day of accrual, the U.S. Shareholder will recognize a currency gain or loss for U.S. federal income tax purposes.

A non-U.S. Shareholder’s portion of any interest income earned by the Trust generally will not be subject to U.S. federal income tax unless the Shares owned by such non-U.S. Shareholder are effectively connected with the conduct by the non-U.S. Shareholder of a trade or business in the United States.
