2020 full year results & Business updates

"At the heart of HUTCHMED lies a prolific in-house novel drug discovery and development engine that has produced ten clinical-stage drug candidates and a further seven late-stage preclinical assets in oncology and immunology over the past fifteen years." said Mr. Simon To, Chairman of HUTCHMED. "Our aim is to bring these internally discovered and developed innovations to patients the world-over."

"To support this strategic objective, we have built an oncology and immunology operation with around 1,200 personnel based mainly in our two core markets, China and the U.S. In China, supported by a robust manufacturing infrastructure, our commercial team is now delivering impressive sales results on our first two oncology drugs, ELUNATE(R) in metastatic colorectal cancer and the recently launched SULANDA(R) in neuroendocrine tumors. A New Drug Application was also submitted mid-last year for savolitinib in lung cancer and, subject to approval, it will be our third approved oncology drug and the first-in-class selective MET inhibitor on the market in China."

"Outside China, our fast expanding international organization, led mainly from the U.S., is developing five un-partnered oncology drug candidates. In 2020, it achieved three U.S. Food and Drug Administration fast track designations and initiated the rolling submission of surufatinib, our first U.S. New Drug Application filing."

"Over the next three years, we will continue to grow our R&D and commercial organizations globally to support the anticipated launch of our oncology drugs in China, the U.S. and Europe."

VI. EVOLUTION OF OUR CORPORATE IDENTITY

Today we announce the consolidation of the two corporate identities that we have used since our inception. Hutchison China MediTech, or Chi-Med, has been used as our group identity, while Hutchison MediPharma has been the identity of our novel drug R&D(43) operations under which our oncology products have been developed and are now being marketed. We believe now is the right time to consolidate to a single and ubiquitous corporate identity that captures the history and brand equity we have built over the past twenty years.

Therefore, we have chosen to rename ourselves HUTCHMED. The brand HUTCHMED will immediately replace Chi-Med as our abbreviated name. We plan to formally change our group company name at our Annual General Meeting in April 2021, and the names of our key subsidiary companies over the balance of 2021. Our ticker symbol, HCM, will remain unchanged on the Nasdaq Global Select Market and the AIM market of the London Stock Exchange. We have also changed our website to www.hutch-med.com. The information required pursuant to AIM Rule 26 may be found at this address.

VII. IMPACT OF COVID-19

The COVID-19 outbreak initially posed some challenges to our operations in 2020 resulting from restrictions in travel. Our teams adapted quickly and were able to minimize the effect across our businesses. We will continue to closely monitor the evolving situation.

Full Year 2020 Financial Results

Change in Segment Reporting:

As a consequence of our recent commercialization of both ELUNATE(R) and SULANDA (R) and the possible approval and launch of savolitinib during 2021, we have decided to change the manner in which we report segment results in our financial statements. Effective from the year ended December 31, 2020, we will report two segments, (1) Oncology/Immunology, covering all activities related to oncology/immunology including sales, marketing, manufacturing and research and development with respect to our drugs and drug candidates; and (2) Other Ventures, which includes all other HUTCHMED businesses. We have retrospectively revised prior period segment information to conform to current period presentation in the financial information contained in this announcement.

Cash, Cash Equivalents and Short-Term Investments were $435.2 million as of December 31, 2020 compared to $217.2 million as of December 31, 2019.

-- Adjusted Group (non-GAAP(44) ) net cash flows excluding financing activities were -$78.4 million (2019: -$82.3m) mainly due to Oncology/Immunology R&D spending and partially offset by dividends received from our non-consolidated joint ventures totaling $86.7 million (2019: $28.1m); and

-- Net cash generated from financing activities in 2020 totaled $296.4 million (2019: -$1.5m) mainly resulting from a Nasdaq follow-on offering in January 2020 and two private placements to General Atlantic(45) and CPP Investments(46) completed in July and November 2020 respectively.

Revenues for the year ended December 31, 2020 was $228.0 million compared to $204.9 million in 2019.

-- Oncology/Immunology consolidated revenues were $ 30.2 million (2019 : $26.8m) comprised of $20.0 million (2019: $10.8m) in manufacturing revenues, promotion and marketing service revenues and royalties from the commercial sale of ELUNATE (R) ; and $10.2 million (2019: $16.0m) in research and development service fee revenues primarily from AstraZeneca and Lilly ; and

-- Other Ventures consolidated revenues increased 11% (11% at CER(47) ) to $197.8 million (2019: $178.1m) mainly due to continued sales growth of third-party prescription drug products .

Net Expenses for the year ended December 31, 2020 were $353.7 million compared to $310.9 million in 2019.

-- Cost of Sales were $188.5 million (2019: $160.2m), the majority of which was the cost of third-party prescription drug products marketed through our profitable Other Ventures;

-- R&D Expenses were $174.8 million (2019: $138.2m) mainly as a result of an expansion in the development of our ten novel oncology drug candidates. With six now in global development, our rapidly scaling international clinical and regulatory operations in the U.S. and Europe incurred expenses of $63.3 million (2019: $21.7m) while R&D expense in China was stable at $111.5 million (2019: $116.5m);

-- SG&A(48) Expenses were $61.3 million (2019: $52.9m) primarily due to increases in staff costs and share-based compensation to support expanding operations. This included the build-up of a large-scale national oncology commercial infrastructure in China to support the launch of SULANDA(R) and the assumption of commercial responsibility on ELUNATE(R) ; and

-- Other Items(49) generated net income of $70.9 million (2019: $40.4m) resulting primarily from an increase in our share of equity in the earnings from equity investees under our Other Ventures in China which delivered solid underlying net income growth of 7% (9% at CER) in 2020 and also benefited from a one-time land compensation gain of $28.8 million (2019: nil).

Net Loss attributable to HUTCHMED for the year ended December 31, 2020 was $125.7 million compared to $106.0 million in 2019.

-- As a result, the net loss attributable to HUTCHMED in 2020 was $0.18 per ordinary share / $0.90 per ADS(50) compared to net loss attributable to HUTCHMED of $0.16 per ordinary share / $0.80 per ADS, in 2019.

OPERATIONS REVIEW

Oncology/Immunology

We discover, develop, manufacture and market targeted therapies and immunotherapies for the treatment of cancer and immunological diseases through a fully integrated team of over 600 scientists and staff (December 31, 2019: 500), and an in-house oncology commercial organization of over 420 staff (December 31, 2019: 90).

Currently, we have nine self-discovered oncology drug candidates in clinical trials in China, with six also in clinical development in the U.S. and Europe. Our first two drug candidates, fruquintinib and surufatinib, have been approved and launched by our commercial organization in China.

MARKETED PRODUCT SALES

   Fruquintinib   (ELUNATE(R) in China ) 

ELUNATE(R) was first commercially launched in China, marketed by our partner Lilly, starting in November 2018 for the treatment of advanced CRC. Since launch, Lilly deployed a dedicated team of about 140 oncology commercial personnel to market ELUNATE(R) in China. In January 2020, ELUNATE(R) was included in the NRDL thereby broadening access by advanced CRC patients in China.

In July 2020, we reached an agreement with Lilly for HUTCHMED to take over development and execution of all on-the-ground medical detailing, promotion and local and regional marketing activities for ELUNATE(R) in China. Under the terms of the new agreement, HUTCHMED and Lilly will share gross profits linked to sales target performance. Subject to meeting pre-agreed sales targets, Lilly will pay HUTCHMED an estimated total of 70% to 80% of ELUNATE(R) sales in the form of royalties, manufacturing costs and service payments.

Since taking on these commercial responsibilities in Q4 2020, HUTCHMED has deployed its dedicated team of over 420 oncology commercial personnel to market ELUNATE(R) with sales now increasing rapidly.

* = Unaudited; ** = Represents total sales to third parties as provided by Lilly; *** = Represents manufacturing fees, commercial service fees and royalties paid by Lilly to HUTCHMED, and sales to other third parties invoiced by HUTCHMED.

In 2020, we estimate that ELUNATE(R) achieved approximately 15% penetration (patient share), based on our estimation of the size of the advanced CRC market in China, which would equate to approximately 8,400 patients receiving an average of 4.7 months of treatment (IQVIA).

Driven by inclusion in the NRDL, we are now rapidly expanding hospital pharmacy listings, one of the most important factors affecting broad-scale adoption of ELUNATE(R) in China. In Q4 2020, we increased hospital listings by over 40% to approximately 280 and target to double this level of listings in 2021. Our oncology commercial team currently covers over 2,300 oncology hospitals in China, with ELUNATE(R) prescriptions in hospitals without an in-house pharmacy listing being filled in external retail pharmacies.

We believe that the efficacy and safety benefits of ELUNATE(R) , combined with our deep commercial presence and execution, will position us well to significantly increase our market share in advanced CRC in China in the future.

   Surufatinib   (SULANDA(R) in China ) 

SULANDA(R) was first commercially launched in China in mid-January 2021 for the treatment of advanced non-pancreatic NET. In China, there were an estimated 67,600 newly diagnosed NET patients in 2018, of which an estimated 60% were diagnosed with advanced NETs. Considering the current incidence to prevalence ratio, there may be more than 300,000 patients living with the disease in China.

More than half of NET patients harbor tumors in the gastrointestinal tract. As such, there exists major overlap between the oncology physicians and hospitals in China that treat advanced CRC with ELUNATE(R) and advanced gastrointestinal NETs with SULANDA(R) . We expect that this synergy will enable us to effectively utilize our full oncology commercial organization to market both products.

In January-February 2021, the first two months on the market, the total unaudited sales of SULANDA(R) were $4.9 million.

A number of factors have contributed to the promising start for SULANDA(R) such as, (1) a larger and dedicated oncology commercial team covering over 300 cities in China; (2) extensive pre- and post-launch marketing programs to raise awareness among the over 20,000 oncology physicians in China; and (3) a pricing strategy aimed at maximizing patient access to SULANDA(R) .

Our aim is to have SULANDA(R) included in the 2022 NRDL. Until then we are implementing a broad-scale, means tested, patient access program which could materially reduce out-of-pocket costs for patients. We expect the average duration of treatment for SULANDA(R) for NET patients could be similar to the 9.2 months median PFS(51) in non-pancreatic NET. Competition in the advanced non-pancreatic NET market in China is limited with SULANDA(R) providing a unique mechanism of action against the disease.

With the initiation of rolling NDA submissions to the U.S. FDA for surufatinib in December 2020, we have begun to establish a U.S. oncology commercial organization with the recruitment of a senior leadership team based in New Jersey in preparation for a potential surufatinib U.S. launch in late 2021 or early 2022.

RESEARCH & DEVELOPMENT

savolitinib

Savolitinib is an oral, potent, and highly selective small molecule inhibitor of MET. In global partnership with AstraZeneca, savolitinib has been studied in NSCLC, PRCC and gastric cancer in over 1,100 patients to date, both as a monotherapy and in combinations.

Savolitinib - Lung cancer:

MET plays an important role in NSCLC. The table below shows a summary of the clinical studies for savolitinib in lung cancer patients.

NDA accepted in MET Exon 14 skipping alterations NSCLC (NCT02897479) - An estimated 2-3% of NSCLC patients have MET Exon 14 skipping alterations, which lead to poor prognosis. In late 2019, we completed a 70-patient Phase II registration study that was the basis for NDA, which was accepted by the China NMPA in May 2020. Priority review status was granted in July 2020 and, subject to approval, launch is expected in mid-2021.

Results of the Phase II study were presented at ASCO in June 2020 and showed that as of the March 31, 2020 data cut-off, ORR(54) was 49.2% and DCR(55) was 93.4% in 61 efficacy evaluable patients. Median DoR(56) was 9.6 months (95% CI(57) 5.5-NR(58) ) with maturity of 40%. Median PFS was 6.9 months (95% CI 4.2-19.3) with maturity of 50%. Median OS was 14.0 months (95% CI: 9.7-NR) with maturity of 46%. Clinical data demonstrated an acceptable safety profile with a low AE(59) related discontinuations rate of 14.3%.

EGFR TKI-resistance in NSCLC - MET-amplification is a major mechanism for acquired resistance to both first-generation EGFR TKIs, such as IRESSA(R) and TARCEVA(R) , as well as third-generation EGFR TKIs like TAGRISSO(R) . As many as 30% of EGFR mutation positive NSCLC patients develop MET amplification driven resistance to EGFR TKIs. Savolitinib has been studied extensively in these patients in the TATTON and SAVANNAH studies.

SAVANNAH Phase II study of combination with TAGRISSO (R) in patients who have progressed following TAGRISSO(R) due to MET amplification or overexpression (NCT03778229) - The SAVANNAH study is a global single-arm, open-label study. SAVANNAH followed the successful TATTON study, a Phase Ib/II expansion study of savolitinib in combination with TAGRISSO(R) in over 220 EGFR mutation positive TKI refractory NSCLC patients, with final analysis presented at the virtual 2020 WCLC.

The SAVANNAH study has now fully enrolled the savolitinib 300mg QD(60) cohort, and is currently enrolling two additional cohorts of savolitinib 300mg BID(61) and 600mg QD. The SAVANNAH study will also determine optimal design of the planned global Phase III study regarding optimal biomarker strategy and dosage regimen. Enrollment is expected to complete in mid-2021 and planning for the global Phase III study is now underway.

In-Planning - China Phase III study of combination with TAGRISSO (R) in 2L EGFR TKI refractory, MET amplified NSCLC patients - We intend to initiate a Phase III study in China targeting EGFR TKI refractory second-line NSCLC patient in the second half of 2021.

In-Planning - China Phase III study of combination with TAGRISSO (R) in EGFR mutant and MET positive NSCLC patients - We intend to initiate a Phase III study in China targeting treatment naïve patients who are both EGFR mutation and MET positive in the second half of 2021.

Savolitinib - Kidney cancer:

MET+ PRCC - PRCC is the most common of the non-clear cell RCC, representing approximately 14% of kidney cancer. Approximately 400,000 new cases of kidney cancer were diagnosed globally in 2018, equating to about 56,500 cases of PRCC, with approximately 40% harboring MET driven disease. No targeted therapies have been approved specifically for PRCC.

SAVOIR Phase III in MET-positive PRCC (NCT03091192) - In late 2018, the SAVOIR study, a global Phase III study of savolitinib monotherapy compared with SUTENT(R) (sunitinib) in patients with MET-driven PRCC, was stopped early with 60 patients randomized at the time, due to confounding data from a separate, external, retrospective molecular epidemiology study.

Results from the 60 randomized patients (33 savolitinib, 27 sunitinib) were promising and data was presented at ASCO in May 2020. In terms of OS, savolitinib patients had not reached median OS at data cut-off, compared to 13.2 months for sunitinib patients (HR(63) 0.51; 95% CI: 0.21-1.17; p=0.110). Median PFS was 7.0 months for savolitinib patients, compared to 5.6 for sunitinib patients (HR 0.71; 95% CI 0.37-1.36; p=0.313). Responses were observed in 27% and 7% of savolitinib and sunitinib patients, respectively. This difference did not reach statistical significance due to the small sample size. In terms of safety, Grade >= 3 AEs were reported in 42% of savolitinib patients versus 81% of sunitinib patients, with AEs leading to dose modification in 30% and 74% of savolitinib and sunitinib patients, respectively.

Savolitinib and Immunotherapy Combinations - Evidence is emerging demonstrating that MET plays an important role in the tumor microenvironment, leading to reduced anti-tumor activity of immune cells in many solid tumors. Therefore, combining immunotherapies with a MET inhibitor is hypothesized to enhance anti-tumor activity.

CALYPSO Phase II in combination with IMFINZI(R) PD-L1 inhibitor in RCC (NCT02819596) - The CALYPSO study is an investigator initiated open-label Phase I/II study of savolitinib in combination with IMFINZI(R) . The study is evaluating the safety and efficacy of the savolitinib/IMFINZI(R) combination in patients with PRCC and clear cell RCC at sites in the U.K. and Spain.

CALYPSO PRCC cohort - Interim data for the PRCC cohort of the CALYPSO Phase II study were presented at ASCO GU 2020 reporting an ORR of 27%, median PFS of 4.9 months (95% CI: 2.5, 12.0) and median OS of 12.3 months (95% CI: 5.8, 21.3). Tolerability was in line with established single agent safety profiles.

In-Planning - Phase III in combination with IMFINZI(R) PD-L1 inhibitor in MET-driven, unresectable and locally advanced or metastatic PRCC - Based on the encouraging results of the SAVOIR and CALYPSO studies, we intend to initiate a global Phase III, open-label, randomized, controlled study of savolitinib plus IMFINZI(R) versus sunitinib monotherapy versus IMFINZI(R) monotherapy in patients with MET-driven, unresectable and locally advanced or metastatic PRCC. The study is expected to begin enrollment by mid-2021.

Savolitinib - Gastric cancer:

MET-driven gastric cancer has a very poor prognosis. Multiple Phase II studies have been conducted in Asia to study savolitinib in MET-driven gastric cancer patients. The VIKTORY study is an investigator initiated Phase II umbrella study in gastric cancer in South Korea in which a total of 715 patients were successfully sequenced into 10 molecular-driven patient groups. Patients with MET amplification (25/715, or 3.5% of patients) were treated with savolitinib monotherapy, reporting an ORR of 50% (10/20, 95% CI: 28.0, 71.9), meeting pre-specified 6-week PFS rates and warranting further study.

In-Planning - China Phase II study with potential for registration intent in 2L+ gastric cancer with MET amplification - In mid-2021, we intend to initiate a Phase II registration-intent study in MET-amplified gastric cancer in China. This is a two-stage, single-arm study which targets advanced gastric cancer patients who have failed at least one line of treatment. The primary endpoint is ORR. Subject to the results of the first-stage of this study we will discuss with the CDE(64) of NMPA the appropriate approach and necessary criteria for registration.

Surufatinib

Surufatinib is a novel, oral angio-immuno kinase inhibitor that selectively inhibits the tyrosine kinase activity associated with VEGFR and FGFR, both shown to be involved in tumor angiogenesis, and CSF-1R, which plays a key role in regulating tumor-associated macrophages, promoting the body's immune response against tumor cells. Surufatinib has been studied in over 900 patients to date, both as a monotherapy and in combinations, and is approved in China.

We currently retain all rights to surufatinib worldwide. A summary of the clinical studies of surufatinib is shown in the table below.

Surufatinib - NET:

NETs present in the body's organ system with fragmented epidemiology. About 55-75% of NETs originate in the GI(68) tract and pancreas, 25-30% in the lung or bronchus, and a further 10-20% in other organs or unknown origins.

Global development of surufatinib in NET - In June 2020, we held a pre-NDA meeting with the U.S. FDA for the treatment of patients with advanced NET and reached an agreement that the completed SANET-ep (non-pancreatic NET) and SANET-p (pancreatic NET) studies, along with existing data from surufatinib in U.S. non-pancreatic and pancreatic NET patients, could form the basis to support a U.S. NDA submission. The FDA granted Fast Track Designations for our pancreatic and non-pancreatic NET development programs in April 2020, following Orphan Drug Designation for pancreatic NET in November 2019.

In December 2020, we initiated the filing of a NDA to the U.S. FDA - the first portion of a rolling submission for surufatinib for the treatment of pancreatic and non-pancreatic NET. We plan to complete the NDA submission in the first half of 2021, which would be our first NDA in the U.S. Filing acceptance of the NDA is subject to FDA review of the complete application.

We also plan to file a MAA to the EMA in mid-2021, based on scientific advice from the EMA's CHMP(69) .

U.S. Phase Ib NET cohorts (NCT02549937) - At ASCO 2020, preliminary data presented from the two NET cohorts in the ongoing U.S. Phase Ib trial for surufatinib demonstrated efficacy comparable to China data in heavily pretreated patients, including AFINITOR (R) and SUTENT (R) , with pancreatic or non-pancreatic NETs. The safety profile was also consistent with the larger pool of surufatinib safety data. As of April 21, 2020, 16 patients with pancreatic NET were treated for a median of 7.1 months (range 2.0-17.5) and 16 patients with non-pancreatic NET were treated for a median of 4.9 months (range of 1.0-10.2). All 32 patients have pretreated progressive NETs (median prior lines of treatment: 3; range 1-8). Confirmed response was observed in 18.8% of pancreatic NET patients; all remaining patients had stable disease (including 1 unconfirmed response), for a DCR of 100%. In the non-pancreatic NET cohort all patients had stable disease (including 1 unconfirmed response).

Pharmacokinetic and safety data from these cohorts was presented at AACR 2020, demonstrating similar profiles of surufatinib between Chinese and U.S. patients, meaning that race had minimal effect on exposure.

Surufatinib in SANET-ep (NCT02588170) - In December 2020, surufatinib was granted approval for drug registration by the NMPA for the treatment of non-pancreatic NET. The approval was based on results from the SANET-ep study, a Phase III trial in patients with advanced non-pancreatic NET conducted in China. The study met the pre-defined primary endpoint of PFS at a preplanned interim analysis. The results of this trial were highlighted in an oral presentation at the 2019 ESMO Congress and published in The Lancet Oncology in September 2020. Median PFS for patients treated with surufatinib was 9.2 months, compared to 3.8 months for patients in the placebo group (HR 0.334; 95% CI: 0.223-0.499; p<0.0001). Surufatinib had an acceptable safety profile, with the most common treatment-related adverse events of grade 3 or worse being hypertension (36% of surufatinib patients vs. 13% of placebo patients), proteinuria (19% vs. 0%) and anemia (5% vs. 3%).

Phase III study of surufatinib in SANET-p (NCT02589821) - The SANET-p study is a pivotal Phase III study in patients with low- or intermediate-grade, advanced pancreatic NET in China. In early 2020 it was terminated early as the pre-defined primary endpoint of PFS was met at a preplanned interim analysis, leading to a second NDA accepted by the NMPA in September 2020. The results of this study were presented at the ESMO Virtual Congress 2020 and published simultaneously in The Lancet Oncology.

Median PFS was 10.9 months for patients treated with surufatinib, as compared to 3.7 months for patients in the placebo group (HR 0.491; 95% CI: 0.319-0.755; p=0.0011). ORRs were 19.2% for the efficacy evaluable patients in the surufatinib group versus 1.9% for the placebo group, with a DCR of 80.8% versus 66.0%, respectively. Most patients in the trial had Grade 2 disease with heavy tumor burden, including liver metastasis and multiple organ involvement. Efficacy was also supported by BIIRC(70) assessment, with a median PFS of 13.9 months for surufatinib as compared to 4.6 months for placebo (HR 0.339; 95% CI 0.209-0.549; p<0.0001). The safety profile of surufatinib was manageable and consistent with observations in prior studies. Treatment was well tolerated for most patients, with discontinuation rates as a result of treatment emergent adverse events of 10.6% in the surufatinib group as compared to 6.8% in the placebo group.

The positive SANET-ep and SANET-p Phase III studies now position surufatinib to potentially be approved in the full spectrum of advanced-NET disease in China. We believe that no other approved targeted therapy can address and treat all subtypes of NETs.

Surufatinib - BTC:

Phase IIb/III study of surufatinib monotherapy in second line BTC (NCT03873532) - In March 2019, based on preliminary Phase Ib/IIa data, we initiated a registration-intent Phase IIb/III study comparing surufatinib with capecitabine in patients with unresectable or metastatic BTC whose disease progressed on first-line chemotherapy. The primary endpoint is OS. Enrollment for the BTC monotherapy Phase II portion (80 patients) was completed in 2020, and we expect to conduct an interim analysis for futility in 2021 when OS data are mature. The interim analysis and assessment of the current treatment landscape in BTC will inform our further development strategy.

Surufatinib - Combinations with Checkpoint Inhibitors:

Surufatinib's ability to inhibit angiogenesis, block the accumulation of tumor associated macrophages and promote infiltration of effector T cells into tumors, could help improve the anti-tumor activity of PD-1 antibodies.

In late 2018, we entered into a global collaboration with Junshi to evaluate the combination of surufatinib with TUOYI(R) . We have completed a Phase I dose-finding study and presented the data at the AACR Conference in April 2020. The data showed that surufatinib plus TUOYI (R) were well tolerated with no unexpected safety signals observed. At the RP2D(71) , a DCR of 100% and ORR of 63.6% were reported for 11 efficacy evaluable patients, with 2 unconfirmed PRs(72) . Surufatinib plus TUOYI (R) showed encouraging antitumor activity in patients with advanced solid tumors. A Phase II China study is rapidly enrolling patients in nine solid tumor indications, including NENs, BTC, gastric cancer, thyroid cancer, SCLC, soft tissue sarcoma, endometrial cancer, esophageal cancer and NSCLC.

In the first half of 2021, we expect to start an open-label Phase Ib/II study in the U.S. of surufatinib in combination with tislelizumab evaluating the safety, tolerability, pharmacokinetics and efficacy in patients with advanced solid tumors, including CRC, NET, SCLC, gastric cancer and soft tissue sarcoma.

In addition, we have expanded our collaboration with Innovent and, in July 2020, started a Phase I study in China to evaluate the safety and efficacy of TYVYT(R) in combination with surufatinib.

Surufatinib - Exploratory development:

We are now conducting multiple Phase Ib expansion cohorts in the U.S. to explore surufatinib use in BTC and soft tissue sarcoma. In China, we intend to initiate multiple exploratory studies, both as a single agent, and in combinations, to evaluate efficacy of surufatinib. We are also supporting dozens of investigator-initiated studies in various tumor settings.

Fruquintinib

Fruquintinib is a novel, selective, oral inhibitor of VEGFR 1/2/3 kinases that was designed to improve kinase selectivity to minimize off-target toxicity and thereby improve tolerability. Fruquintinib has been studied in over 2,200 patients to date, both as a monotherapy and in combinations.

We retain all rights to fruquintinib outside of China and are partnered with Lilly in China. The table below shows a summary of the clinical studies for fruquintinib.

Fruquintinib - CRC:

Fruquintinib capsules, sold under the brand name ELUNATE(R) , are approved in China for metastatic CRC patients.

Global development of fruquintinib in metastatic CRC - In June 2020, the U.S. FDA granted Fast Track Designation for the development of fruquintinib, for the treatment of patients with metastatic CRC who have been previously treated with fluoropyrimidine-, oxaliplatin-, and irinotecan-based chemotherapy, a VEGF biological therapy, and, if RAS wild-type, an anti-EGFR therapy.

In July 2020, we initiated a global Phase III registration study, known as the FRESCO-2 study, in refractory metastatic CRC which is expected to enroll over 680 patients from approximately 150 sites in 14 countries. The first patient was dosed in September 2020 in the U.S. and enrollment is targeted to complete in late 2021.

The U.S. FDA, EMA and Japanese PMDA(77) have all acknowledged the totality of the fruquintinib clinical data, including the FRESCO-2 study (if positive), the prior positive Phase III FRESCO study demonstrating improvement in overall survival that led to fruquintinib approval for metastatic CRC in China in 2018, and additional completed and ongoing supporting studies in metastatic CRC, could potentially support an NDA for the treatment of patients with metastatic CRC in the third-line setting.

Encouraging preliminary results of the U.S. Phase I/Ib study were presented at ESMO Congress 2020. As of the data cut-off in August 2020, fruquintinib was generally well-tolerated with preliminary evidence of anti-tumor activity in patients with heavily penetrated refractory metastatic CRC. Among 34 total patients, 16 received prior LONSURF(R) treatment, 8 received STIVARGA(R) treatment and 10 received both LONSURF(R) and STIVARGA(R) treatments. The median duration of fruquintinib treatment was 19.1 weeks, higher than 12.0 weeks of prior LONSURF(R) treatment and 9.2 weeks of prior STIVARGA(R) treatment among patients in this trial. DCR in 31 evaluable patients was 80.6%. The safety profile was consistent with that seen in the FRESCO study.

Fruquintinib - Gastric Cancer:

Phase III study of fruquintinib in combination with paclitaxel in gastric cancer (second-line) (NCT03223376) -The FRUTIGA study is a randomized, double-blind, Phase III study in China to evaluate the efficacy and safety of fruquintinib combined with paclitaxel compared with paclitaxel monotherapy, at a 1:1 ratio, for second-line treatment of advanced gastric cancer. The FRUTIGA study primary endpoint is OS.

In June 2020, the IDMC of the FRUTIGA study completed a second planned interim data review and, based on the preset criteria, the IDMC and Joint Steering Committees recommended that the trial continue with a sample size increase to 700 patients. We expect to complete enrollment of FRUTIGA around the year end of 2021.

Fruquintinib - Combinations with Checkpoint Inhibitors:

Phase Ib/II dose expansion study in China of fruquintinib plus TYVYT(R) is underway in different tumor types, including HCC, endometrial cancer, RCC and GI tumors. Moreover, Phase Ib studies of fruquintinib plus geptanolimab, Genor's(78) anti-PD-1 antibody, in second-line CRC and NSCLC are also underway.

In the first half of 2021, we expect to start an open-label, multi-center, non-randomized, Phase Ib/II study in the U.S. to assess the safety and efficacy of fruquintinib in combination with tislelizumab in patients with advanced, refractory triple negative breast cancer. Another Phase II study is being planned to assess the efficacy and safety of the combination in patients with advanced or metastatic, unresectable gastric cancer and CRC.

Fruquintinib - Exploratory development:

We are conducting multiple Phase Ib expansion cohorts in the U.S. to explore fruquintinib in CRC and breast cancer. In China, we are currently supporting dozens of investigator-initiated studies in various solid tumor settings.

HMPL-689

HMPL-689 is a novel, selective oral inhibitor targeting the isoform PI3K , a component in the B-cell receptor signaling pathway. HMPL-689's pharmacokinetic properties are favorable with good oral absorption, moderate tissue distribution and low clearance in preclinical studies, we therefore anticipate low risk of drug accumulation and drug-to-drug interaction. We currently retain all rights to HMPL-689 worldwide. The table below shows a summary of the clinical studies for HMPL-689.

In December 2020, we presented preliminary results from a Phase I dose escalation study of HMPL-689 in Chinese patients with relapsed/refractory lymphoma at the ASH Annual Meeting. A total of 56 patients were enrolled resulting in an ORR of 51.9% (27/52) and complete response rate of 21.2% (11/52) in efficacy evaluable patients. The median DOR was 9.2 months (3.9-NR). One patient with follicular lymphoma who achieved complete response (per post hoc independent radiologic review) was on treatment for over 19 months. In the nine efficacy evaluable patients treated with the RP2D of 30mg QD orally in Chinese patients, efficacy was encouraging with an ORR of 100% (4/4) in follicular lymphoma, 100% in marginal zone lymphoma (2/2) and 67% (2/3) in diffuse large B cell lymphoma.

HMPL-689 was well tolerated at the RP2D exhibiting dose-proportional pharmacokinetics and a manageable toxicity profile. The most common Grade >= 3 non-hematologic TEAEs(79) were pneumonia and hypertension. Grade >= 3 hematologic TEAEs were neutropenia, and no Grade 5 TEAEs were reported.

The Phase Ib dose expansion study in China is ongoing in multiple sub-categories of indolent non-Hodgkin's lymphoma. Based on the encouraging preliminary results, we are now planning registration studies in select indolent non-Hodgkin's lymphoma in China, which are anticipated to start in mid-2021.

Furthermore, we have initiated a Phase I/Ib study in the U.S. and Europe, with patient enrollment underway. Dose escalation is near complete and we expect to be able to engage with regulatory authorities in mid-2021 to align potential registration pathway with a target to initiate registration studies in 2021.

HMPL-523

In July 2020, we initiated our Phase I development in China. This is a multi-center study to evaluate the safety, pharmacokinetics, pharmacodynamics and efficacy of HMPL-306 in patients of relapsed or refractory hematological malignancies with an IDH1 and/or IDH2 mutation. Multiple sites have been initiated and we anticipate to be able to establish the Phase II dose during 2021.

In the U.S., IND applications for solid tumors and hematologic malignancies were cleared in October 2020. We expect to initiate Phase I development in the U.S. during the first half of 2021.

HMPL-295

HMPL-295, a novel ERK inhibitor, is our 10(th) in-house discovered small molecule oncology drug candidate. ERK is a downstream component of the RAS-RAF-MEK-ERK signaling cascade (MAPK pathway). This is our first of multiple candidates in discovery targeting the MAPK pathway.

RAS and RAF mutations are present in almost 50% of human cancers, predict worse clinical prognosis in a wide variety of tumor types, mediate resistance to targeted therapies, and decrease the response to standard of care, target therapy and immunotherapy. On the MAPK pathway, KRAS inhibitors are under clinical evaluation, and acquired resistance develops for RAF/MEK targeted therapies. ERK inhibition has the potential to overcome or avoid the intrinsic or acquired resistance from upstream mechanisms.

We currently retain all rights to HMPL-295 worldwide. Planning for the Phase I study in China is now underway and set to start in mid-2021.

DISCOVERY RESEARCH & PRECLINICAL DEVELOPMENT

We strive to create differentiated novel oncology and immunology treatments with global potential. These include furthering both small molecule and monoclonal antibody therapies which address aberrant genetic drivers; cancer cell metabolism; modulate tumor immune microenvironment; and target immune cell checkpoints. We design drug candidates with profiles that enable them to be used in innovative combinations with other therapy, such as chemotherapy, immunotherapy and other targeted therapy in order to attack disease simultaneously through multiple modalities and pathways. We believe that this approach can significantly improve treatment outcomes for patients.

In addition to the ten clinical-stage assets, we have three more novel oncology drug candidates in late-preclinical stage, including HMPL-653 (targeting solid tumors), HMPL-A83 (targeting solid tumors and hematological malignancies) and HMPL-760 (targeting hematological malignancies). We retain all worldwide rights to these assets and are targeting dual U.S. and China IND submissions during 2021.

NEW MANUFACTURING FACILITY IN SHANGHAI

In December 2020, we held a ground-breaking ceremony in Zhangjiang Hi-Tech Park, Shanghai, commencing construction of a large-scale manufacturing plant for innovative drugs. The $130 million Shanghai factory will be our largest manufacturing facility, with production capacity estimated to be five times that of our manufacturing plant in Suzhou. The Shanghai factory site spans approximately 28,700 square meters. Constructed in two phases, the buildings will have a total floorplan of almost 55,000 square meters. The first phase will be primarily for small molecule production, with production capacity expected to be able to produce 250 million tablets and capsules per year, five-fold the capacity of our current Suzhou facility. The second phase will include expansion into large molecule production.

The current Suzhou site is a GMP(80) -certified production facility, supplying drug candidates for clinical trials and the commercialization of ELUNATE(R) and SULANDA(R) . We plan to continue to invest resources in the Suzhou facility, expanding the production team in phases.

IMMUNOLOGY COLLABORATION WITH INMAGENE

In January 2021, we entered into a strategic partnership with Inmagene, a clinical development stage company with a focus on immunological diseases, to further develop four novel preclinical drug candidates discovered by us for the potential treatment of multiple immunological diseases. Funded by Inmagene, we will work together to move the drug candidates towards IND. If successful, Inmagene will then advance the drug candidates through global clinical development.

OTHER VENTURES

Our Other Ventures include drug marketing and distribution platforms covering about 320 cities and towns in China with around 4,800 mainly manufacturing and commercial personnel. Built over the past 20 years, it primarily focuses on prescription drug and consumer health products through several joint ventures and subsidiary companies.

In 2020, our Other Ventures delivered encouraging growth with consolidated revenues up 11% (11% at CER) to $197.8 million (2019: $178.1m). Consolidated net income attributable to HUTCHMED from our Other Ventures increased by 75% (77% at CER) to $72.8 million (2019: $41.5m), and excluding the one-time gain of $28.8 million in 2020 (2019: nil) from land compensation, net income attributable to HUTCHMED grew by 6% (8% at CER) to $44.0 million (2019: $41.5m).

SHPL(81) : Our own-brand prescription drugs business, operated through our non-consolidated joint venture SHPL grew sales by 2% (3% at CER) to $276.4 million (2019: $272.1m). This sales growth and favorable product mix led to an increase of 9% (12% at CER) in net income attributable to HUTCHMED to $33.5 million (2019: $30.7m).

The SHPL operation is large-scale, with a commercial team of about 2,2 00 staff managing the medical detailing and marketing of its products not just in hospitals in provincial capitals and medium-sized cities, but also in the majority of county-level hospitals in China. SHPL's GMP-certified factory holds 74 drug product manufacturing licenses and is operated by over 530 manufacturing staff .

SXBX(82) pill : SHPL's main product is SXBX pill, an oral vasodilator prescription therapy for coronary artery disease. SXBX pill is the third largest botanical prescription drug in this indication in China, with a national market share in 2020 of 18.2% (2019: 18.0%) . Sales increased by 4% (6% at CER) to $250.0 million in 2020 (2019: $239.5m).

SXBX pill is protected by a formulation patent that expires in 202 9 and is one of less than two dozen proprietary prescription drugs represented on China's National Essential Medicines List, which means that all Chinese state-owned health care institutions are required to carry it. SXBX pill is fully reimbursed in all China .

Hutchison Sinopharm(83) : Our prescription drugs commercial services business, which in addition to providing certain commercial services for our own products, provides services to third-party pharmaceutical companies in China and sales grew by 15% (15% at CER) to $165.1 million (2019: $143.7m) in 2020.

Hutchison Sinopharm has a dedicated team of over 120 commercial staff focused on two key areas of operation. First, a team that markets third-party prescription drug products directly to over 500 public and private hospitals in the Shanghai region and through a network of over 40 distributors to cover all other provinces in China. Second, a team that markets HUTCHMED's science-based infant nutrition products through a network over 29,000 promoters in China.

HBYS: Our own-brand OTC(84) drugs business, operated through our non-consolidated joint venture HBYS grew sales 8% (8% at CER) to $232.4 million (2019: $215.4m), mainly as a result of a 30% increase in sales of Banlangen, an anti-viral product, in 2020 due to COVID-19. This growth combined with the land compensation detailed below led to an increase of 361% (361% at CER) in net income attributable to HUTCHMED to $36.5 million (2019: $7.9m) including a one-time land compensation gain of $28.8 million (2019: nil) .

HBYS' Bai Yun Shan brand is a market-leading, household name, known by the majority of Chinese consumers with 185 drug product licenses . In addition to about 1,000 manufacturing staff in Guangdong and Anhui, HBYS has a co mmercial team of about 900 commercial staff that cove r the national retail pharmacy channel in China .

HBYS property update: In June 2020, we entered into an agreement with the Guangzhou government for the return of HBYS's remaining 34 years' land-use rights on its 30,000 square meters unused site in Guangzhou in return for cash compensation of up to approximately $100 million. In 2020, HBYS received about $40 million and is expected to receive about $43 million in 2021. In addition, subject to the Guangzhou government's confirmation of completion of the remaining administrative procedures before June 2021, HBYS will be further entitled to receive about $17 million in compensation. The land return had no impact on HBYS manufacturing operations, which continue to be conducted at larger sites in Guangzhou and Bozhou, Anhui province.

Other Ventures dividends: The profits of our various Other Ventures businesses are passed to the HUTCHMED Group through dividend payments primarily from our non-consolidated joint ventures, SHPL and HBYS. In 2020, dividends of $86.7 million (2019: $28.1m) were paid from these joint ventures to the HUTCHMED Group level with aggregate dividends received since inception of over $300 million.

USE OF NON-GAAP FINANCIAL MEASURES AND RECONCILIATION

In addition to financial information prepared in accordance with U.S. GAAP, this announcement also contains certain non-GAAP financial measures based on management's view of performance including:

   --      Adjusted Group net cash flows excluding financing activities 
   --      CER 

Management uses such measures internally for planning and forecasting purposes and to measure the HUTCHMED Group's overall performance. We believe these adjusted financial measures provide useful and meaningful information to us and investors because they enhance investors' understanding of the continuing operating performance of our business and facilitate the comparison of performance between past and future periods. These adjusted financial measures are non-GAAP measures and should be considered in addition to, but not as a substitute for, the information prepared in accordance with U.S. GAAP. Other companies may define these measures in different ways.

Adjusted Group net cash flows excluding financing activities: We include the change in short-term investments for the period to the change in cash and cash equivalents for the period, and exclude the net cash (generated from)/used in financing activities for the period to derive our adjusted Group net cash flows excluding financing activities. We believe the presentation of adjusted Group net cash flows excluding financing activities provides useful and meaningful information about the change in our cash resources excluding those from financing activities which may present significant period-to-period differences.

CER: We remove the effects of currency movements from year-to-year comparisons by retranslating the current year's performance at previous year's foreign currency exchange rates. Because we have significant operations in China, the RMB to U.S. dollar exchange rates used for translation may have a significant effect on our reported results. We believe the presentation at CER provides useful and meaningful information because it facilitates year-to-year comparisons of our results and increases the transparency of our underlying performance.

Reconciliation of GAAP change in cash and cash equivalents and short-term investments to Adjusted Group net cash flows excluding financing activities:

Notes to the Consolidated Financial Statements

1. Organization and Nature of Business

Hutchison China MediTech Limited (the "Company") and its subsidiaries (together the "Group") are principally engaged in researching, developing, manufacturing and marketing pharmaceutical products. The Group and its equity investees have research and development facilities and manufacturing plants in the People's Republic of China (the "PRC") and sell their products mainly in the PRC, including Hong Kong. In addition, the Group has established international operations in the United States of America (the "U.S.") and Europe.

The Company was incorporated in the Cayman Islands on December 18, 2000 as an exempted company with limited liability under the Companies Law (2000 Revision), Chapter 22 of the Cayman Islands. The address of its registered office is P.O. Box 309, Ugland House, Grand Cayman, KY1-1104, Cayman Islands.

The Company's ordinary shares are listed on the AIM market of the London Stock Exchange, and its American depositary shares ("ADS"), each representing five ordinary shares, are traded on the Nasdaq Global Select Market.

Liquidity

As at December 31, 2020, the Group had accumulated losses of US$ 415,591,000 primarily due to its spending in drug research and development activities. The Group regularly monitors current and expected liquidity requirements to ensure that it maintains sufficient cash balances and adequate credit facilities to meet its liquidity requirements in the short and long term. As at December 31, 2020, the Group had cash and cash equivalents of US$235,630,000, short-term investments of US$199,546,000 and unutilized bank borrowing facilities of US$69,359,000. Short-term investments comprised of bank deposits maturing over three months. The Group's operating plan includes the continued receipt of dividends from certain of its equity investees. Dividends received from equity investees for the years ended December 31, 2020, 2019 and 2018 were US$86,708,000, US$28,135,000 and US$35,218,000 respectively.

Based on the Group's operating plan, the existing cash and cash equivalents, short-term investments and unutilized bank borrowing facilities are considered to be sufficient to meet the cash requirements to fund planned operations and other commitments for at least the next twelve months (the look-forward period used), and it is appropriate for the Group to prepare the consolidated financial statements on a going concern basis.

Notes:

(a) HHOL is regarded as a subsidiary of the Company, as while both its shareholders have equal representation at the board, in the event of a deadlock, the Group has a casting vote and is therefore able to unilaterally control the financial and operating policies of HHOL.

(b) The 50% equity interest in HBYS is held by an 80% owned subsidiary of the Group. The effective equity interest of the Group in HBYS is therefore 40% for the years presented.

3. Summary of Significant Accounting Policies

Principles of Consolidation and Basis of Presentation

The accompanying consolidated financial statements reflect the accounts of the Company and all of its subsidiaries in which a controlling interest is maintained. Investments in equity investees over which the Group has significant influence are accounted for using the equity method. All inter-company balances and transactions have been eliminated in consolidation. The consolidated financial statements have been prepared in conformity with generally accepted accounting principles in U.S. ("U.S. GAAP").

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period.

Foreign Currency Translation

The Company's presentation currency is the U.S. dollar ("US$"). The financial statements of the Company and its subsidiaries with a functional currency other than the US$ have been translated into the Company's presentation currency. All assets and liabilities of the subsidiaries are translated using year-end exchange rates and revenues and expenses are translated at average exchange rates for the year. Translation adjustments are reflected in accumulated other comprehensive (loss)/income in shareholders' equity.

Net foreign currency exchange gains of US$3,265,000 and US$246,000 and net foreign exchanges losses of US$233,000 were recorded in other income and other expense in the consolidated statements of operations for the years ended December 31, 2020, 2019 and 2018 respectively.

Cash and Cash Equivalents

The Group considers all highly liquid investments purchased with original maturities of three months or less to be cash equivalents. Cash and cash equivalents consist primarily of cash on hand and bank deposits and are stated at cost, which approximates fair value.

Short-term Investments

Short-term investments include deposits placed with banks with original maturities of more than three months but less than one year.

Concentration of Credit Risk

Financial instruments that potentially expose the Group to concentrations of credit risk consist primarily of cash and cash equivalents, short-term investments, accounts receivable, other receivables and amounts due from related parties.

The Group places substantially all of its cash and cash equivalents and short-term investments in major financial institutions, which management believes are of high credit quality. The Group has a practice to limit the amount of credit exposure to any particular financial institution.

The Group has no significant concentration of credit risk. The Group has policies in place to ensure that sales are made to customers with an appropriate credit history and the Group performs periodic credit evaluations of its customers. Normally the Group does not require collateral from trade debtors.

Foreign Currency Risk

The Group's operating transactions and its assets and liabilities in the PRC are mainly denominated in Renminbi ("RMB"), which is not freely convertible into foreign currencies. The Group's cash and cash equivalents denominated in RMB are subject to government controls. The value of the RMB is subject to fluctuations from central government policy changes and international economic and political developments that affect the supply and demand of RMB in the foreign exchange market. In the PRC, certain foreign exchange transactions are required by law to be transacted only by authorized financial institutions at exchange rates set by the People's Bank of China (the "PBOC"). Remittances in currencies other than RMB by the Group in the PRC must be processed through the PBOC or other PRC foreign exchange regulatory bodies which require certain supporting documentation in order to complete the remittance.

Accounts Receivable

Accounts receivable are stated at the amount management expects to collect from customers based on their outstanding invoices. The allowance for credit losses reflects the Group's current estimate of credit losses expected to be incurred over the life of the receivables. The Group considers various factors in establishing, monitoring, and adjusting its allowance for credit losses including the aging of the accounts and aging trends, the historical level of charge-offs, and specific exposures related to particular customers. The Group also monitors other risk factors and forward-looking information, such as country risk, when determining credit limits for customers and establishing adequate allowances for credit losses. Accounts receivable are written off after all reasonable means to collect the full amount (including litigation, where appropriate) have been exhausted.

Inventories

Inventories are stated at the lower of cost or net realizable value. Cost is determined using the weighted average cost method. The cost of finished goods comprises raw materials, direct labor, other direct costs and related production overheads (based on normal operating capacity). Net realizable value is the estimated selling price in the ordinary course of business, less applicable variable selling expenses. A provision for excess and obsolete inventory will be made based primarily on forecasts of product demand and production requirements. The excess balance determined by this analysis becomes the basis for excess inventory charge and the written-down value of the inventory becomes its cost. Written-down inventory is not written up if market conditions improve.

Property, Plant and Equipment

Property, plant and equipment consist of buildings, leasehold improvements, plant and equipment, furniture and fixtures, other equipment and motor vehicles. Property, plant and equipment are stated at cost, net of accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the depreciable assets.

 
 Buildings                                 20 years 
 Plant and equipment                       5-10 years 
 Furniture and fixtures, other equipment 
  and motor vehicles                       4-5 years 
 Leasehold improvements                    Shorter of (a) 5 years or (b) remaining 
                                            term of lease 
 

Additions and improvements that extend the useful life of an asset are capitalized. Repairs and maintenance costs are expensed as incurred.

Impairment of Long-Lived Assets

The Group evaluates the recoverability of long-lived assets in accordance with authoritative guidance on accounting for the impairment or disposal of long-lived assets. The Group evaluates long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. If indicators of impairment exist, the first step of the impairment test is performed to assess if the carrying value of the net assets exceeds the undiscounted cash flows of the assets. If yes, the second step of the impairment test is performed in order to determine if the carrying value of the net assets exceeds the fair value. If yes, impairment is recognized for the excess.

Leasehold Land

Leasehold land represents fees paid to acquire the right to use the land on which various plants and buildings are situated for a specified period of time from the date the respective right was granted and are stated at cost less accumulated amortization and impairment loss, if any. Amortization is computed using the straight-line basis over the lease period of 50 years.

Goodwill

Goodwill represents the excess of the purchase price plus fair value of non-controlling interests over the fair value of identifiable assets and liabilities acquired. Goodwill is not amortized, but is tested for impairment at the reporting unit level on at least an annual basis or when an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. When performing an evaluation of goodwill impairment, the Group has the option to first assess qualitative factors, such as significant events and changes to expectations and activities that may have occurred since the last impairment evaluation, to determine if it is more likely than not that goodwill might be impaired. If as a result of the qualitative assessment, that it is more likely than not that the fair value of the reporting unit is less than its carrying amount, the quantitative fair value test is performed to determine if the fair value of the reporting unit exceeds its carrying value.

Other Intangible Assets

Other intangible assets with finite useful lives are carried at cost less accumulated amortization and impairment loss, if any. Amortization is computed using the straight-line basis over the estimated useful lives of the assets.

Borrowings

Borrowings are recognized initially at fair value, net of debt issuance costs incurred. Borrowings are subsequently stated at amortized cost; any difference between the proceeds (net of debt issuance costs) and the redemption value is recognized in the consolidated statements of operations over the period of the borrowings using the effective interest method.

Ordinary Shares

The Company's ordinary shares are stated at par value of US$0.10 per ordinary share. The difference between the consideration received, net of issuance cost, and the par value is recorded in additional paid-in capital.

Treasury Shares

The Group accounts for treasury shares under the cost method. The treasury shares are purchased for the purpose of the LTIP and held by a trustee appointed by the Group (the "Trustee") prior to vesting.

Share-Based Compensation

Share options

The Group recognizes share-based compensation expense on share options granted to employees and directors based on their estimated grant date fair value using the Polynomial model. This Polynomial pricing model uses various inputs to measure fair value, including estimated market value of the Company's underlying ordinary shares at the grant date, contractual terms, estimated volatility, risk-free interest rates and expected dividend yields. The Group recognizes share-based compensation expense in the consolidated statements of operations on a graded vesting basis over the requisite service period, and accounts for forfeitures as they occur.

Share options are classified as equity-settled awards. Share-based compensation expense, when recognized, is charged to the consolidated statements of operations with the corresponding entry to additional paid-in capital.

LTIP

The Group recognizes the share-based compensation expense on the LTIP awards based on a fixed or determinable monetary amount on a straight-line basis for each annual tranche awarded over the requisite period. For LTIP awards with performance targets, prior to their determination date, the amount of LTIP awards that is expected to vest takes into consideration the achievement of the performance conditions and the extent to which the performance conditions are likely to be met. Performance conditions vary by awards, including targets for shareholder returns, free cash flows, revenues, net profit after taxes and/or the achievement of clinical and regulatory milestones.

These LTIP awards are classified as liability-settled awards before the determination date (i.e. the date when the achievement of any performance conditions are known), as they settle in a variable number of shares based on a determinable monetary amount, which is determined upon the actual achievement of performance targets. As the extent of achievement of the performance targets is uncertain prior to the determination date, a probability based on management's assessment of the achievement of the performance targets has been assigned to calculate the amount to be recognized as an expense over the requisite period.

After the determination date or if the LTIP awards have no performance conditions, the LTIP awards are classified as equity-settled awards. If the performance target is achieved, the Group will pay the determined monetary amount to the Trustee to purchase ordinary shares of the Company or the equivalent ADS. Any cumulative compensation expense previously recognized as a liability will be transferred to additional paid-in capital, as an equity-settled award. If the performance target is not achieved, no ordinary shares or ADS of the Company will be purchased and the amount previously recorded in the liability will be reversed and included in the consolidated statements of operations.

Defined Contribution Plans

The Group's subsidiaries in the PRC participate in a government-mandated multi-employer defined contribution plan pursuant to which certain retirement, medical and other welfare benefits are provided to employees. The relevant labor regulations require the Group's subsidiaries in the PRC to pay the local labor and social welfare authority's monthly contributions at a stated contribution rate based on the monthly basic compensation of qualified employees. The relevant local labor and social welfare authorities are responsible for meeting all retirement benefits obligations and the Group's subsidiaries in the PRC have no further commitments beyond their monthly contributions. The contributions to the plan are expensed as incurred.

The Group also makes payments to other defined contribution plans for the benefit of employees employed by subsidiaries outside the PRC. The defined contribution plans are generally funded by the relevant companies and by payments from employees.

The Group's contributions to defined contribution plans for the years ended December 31, 2020, 2019 and 2018 amounted to US$2,660,000, US$3,479,000 and US$2,878,000 respectively.

Revenue Recognition

Revenue is measured based on consideration specified in a contract with a customer, and excludes any sales incentives and amounts collected on behalf of third parties. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Group from a customer, are also excluded from revenue. The Group recognizes revenue when it satisfies a performance obligation by transferring control over a good, service or license to a customer.

Nature of goods and services

The following is a description of principal activities, separated by reportable segments, from which the Company generates its revenue:

   (i)   Oncology/Immunology 

The Oncology/Immunology reportable segment principally generates revenue from license and collaboration contracts as well as revenues related to the sale of Marketed Products developed from Oncology/Immunology (which was represented under Oncology/Immunology in these consolidated financial statements; refer to Note 26). The license and collaboration contracts generally contain multiple performance obligations including (1) the license to the commercialization rights of a drug compound and (2) the research and development services for each specified treatment indication, which are accounted for separately if they are distinct, i.e. if a product or service is separately identifiable from other items in the arrangement and if a customer can benefit from it on its own or with other resources that are readily available to the customer.

The transaction price generally includes fixed and variable consideration in the form of upfront payment, research and development cost reimbursements, contingent milestone payments and sales-based royalties. Contingent milestone payments are not included in the transaction price until it becomes probable that a significant reversal of revenue will not occur, which is generally when the specified milestone is achieved. The allocation of the transaction price to each performance obligation is based on the relative standalone selling prices of each performance obligation determined at the inception of the contract. The Group estimates the standalone selling prices based on the income approach. Control of the license to the drug compounds transfers at the inception date of the collaboration agreements and consequently, amounts allocated to this performance obligation are generally recognized at a point in time. Conversely, research and development services for each specified indication are performed over time and amounts allocated to these performance obligations are generally recognized over time using cost inputs as a measure of progress. The Group has determined that research and development expenses provide an appropriate depiction of measure of progress for the research and development services. Changes to estimated cost inputs may result in a cumulative catch-up adjustment. Royalty revenues are recognized as future sales occur as they meet the requirements for the sales-usage based royalty exception.

Deferred revenue is recognized if allocated consideration is received in advance of the Group rendering research and development services. Accounts receivable is recognized based on the terms of the contract and when the Group has an unconditional right to bill the customer, which is generally when research and development services are rendered.

Revenue recognition from the sales of goods and provision of services for Marketed Products developed from Oncology/Immunology follows revenue recognition policies in Other Ventures below.

(ii) Other Ventures

The Other Ventures reportable segment principally generates revenue from (1) sales of goods, which are the manufacture or purchase and distribution of pharmaceutical products and other consumer health products, and (2) provision of services, which are the provision of sales, distribution and marketing services to pharmaceutical manufacturers. The Group evaluates whether it is the principal or agent for these contracts. Where the Group obtains control of the goods for distribution, it is the principal (i.e. recognizes sales of goods on a gross basis). Where the Group does not obtain control of the goods for distribution, it is the agent (i.e. recognizes provision of services on a net basis). Control is primarily evidenced by taking physical possession and inventory risk of the goods.

Revenue from sales of goods is recognized when the customer takes possession of the goods. This usually occurs upon completed delivery of the goods to the customer site. The amount of revenue recognized is adjusted for expected sales incentives as stipulated in the contract, which are generally issued to customers as direct discounts at the point-of-sale or indirectly in the form of rebates. Sales incentives are estimated using the expected value method. Additionally, sales are generally made with a limited right of return under certain conditions. Revenues are recorded net of provisions for sales discounts and returns.

Revenue from provision of services is recognized when the benefits of the services transfer to the customer over time, which is based on the proportionate value of services rendered as determined under the terms of the relevant contract. Additionally, when the amounts that can be invoiced correspond directly with the value to the customer for performance completed to date, the Group recognizes revenue from provision of services based on amounts that can be invoiced to the customer.

Deferred revenue is recognized if consideration is received in advance of transferring control of the goods or rendering of services. Accounts receivable is recognized if the Group has an unconditional right to bill the customer, which is generally when the customer takes possession of the goods or services are rendered. Payment terms differ by subsidiary and customer, but generally range from 45 to 180 days from the invoice date.

Research and Development Expenses

Research and development costs are expensed as incurred.

Collaborative Arrangements

The Group enters into collaborative arrangements with collaboration partners that fall under the scope of Accounting Standards Codification ("ASC") 808, Collaborative Arrangements ("ASC 808"). The Group records all expenditures for such collaborative arrangements in research and development expenses as incurred, including payments to third party vendors and reimbursements to collaboration partners, if any. Reimbursements from collaboration partners are recorded as reductions to research and development expenses and accrued when they can be contractually claimed.

Government Grants

Grants from governments are recognized at their fair values. Government grants that are received in advance are deferred and recognized in the consolidated statements of operations over the period necessary to match them with the costs that they are intended to compensate. Government grants in relation to the achievement of stages of research and development projects are recognized in the consolidated statements of operations when amounts have been received and all attached conditions have been met. Non-refundable grants received without any further obligations or conditions attached are recognized immediately in the consolidated statements of operations.

Leases

Summary of impact of applying ASC 842

The Group applied ASC 842 to its various leases at the date of initial application of January 1, 2019. As a result, the Group has changed its accounting policy for leases as detailed below. The core principle of ASC 842 is that a lessee should recognize the assets and liabilities that arise from leases. Therefore, the Group recognizes in the consolidated balance sheets liabilities to make lease payments (the lease liabilities) and right-of-use assets representing its right to use the underlying assets for their lease terms. The Group applied ASC 842 using the optional transition method by recognizing the cumulative effect as an adjustment to opening accumulated losses as at January 1, 2019. The comparative information prior to January 1, 2019 has not been adjusted and continues to be reported under ASC 840, Leases ("ASC 840").

The Group assessed lease agreements as at January 1, 2019 under ASC 842, except for short-term leases. The Group elected the short-term lease exception for leases with a term of 12 months or less and recognizes lease expenses for such leases on a straight-line basis over the lease term and does not recognize right-of-use assets or lease liabilities accordingly. As a result of this assessment, the Group recorded an aggregate US$0.7 million in additional lease expenses as a cumulative adjustment to opening accumulated losses upon adoption. Additionally, the Group recognized right-of-use assets and lease liabilities of US$5.7 million and US$6.4 million respectively as at January 1, 2019.

The lease liabilities were measured at the present value of the remaining lease payments, discounted using the lessees' incremental borrowing rate as at January 1, 2019. The Group's weighted average incremental borrowing rate applied on January 1, 2019 was 3.97% per annum.

A reconciliation of the Group's reported operating lease commitments as at December 31, 2018 and the Group's lease liabilities recognized upon adoption of ASC 842 as at January 1, 2019 is as follows:

 
                                                                   (in US$'000)

(b) The Group leases its corporate offices in Hong Kong through a support service agreement with an indirect subsidiary of CK Hutchison Holdings Limited ("CK Hutchison"), which is the Company's indirect major shareholder. The support service agreement may be terminated by giving 3-month advance notice; therefore, there was no lease commitment beyond the 3-month advance notice period as at December 31, 2018. This termination option is not considered probable of exercise for the purposes of applying ASC 842.

The Group recognized right-of-use assets as at January 1, 2019 measured at their carrying amounts as if ASC 842 had been applied since their commencement dates, but discounted using the lessees' incremental borrowing rate as at January 1, 2019.

Recognized right-of-use assets upon adoption were as follows:

 
              (in US$'000) 
 Offices             4,877 
 Factories             383 
 Others                487 
             ------------- 
                     5,747 
             ============= 
 

There were no adjustments to net cash generated from/(used in) operating activities, investing activities or financing activities in the consolidated statement of cash flows.

In applying ASC 842 for the first time, the Group has used the following practical expedients permitted by the standard: (i) no reassessment of whether any expired or existing contracts are or contain leases; (ii) no reassessment of the lease classification for any expired or existing leases; (iii) the exclusion of initial direct costs for the measurement of the right-of-use assets at the date of initial application; and (iv) the use of hindsight in determining the lease term where the contract contains options to extend or terminate the lease.

Updated accounting policy-ASC 842

In an operating lease, a lessee obtains control of only the use of the underlying asset, but not the underlying asset itself. An operating lease is recognized as a right-of-use asset with a corresponding liability at the date which the leased asset is available for use by the Group. The Group recognizes an obligation to make lease payments equal to the present value of the lease payments over the lease term. The lease terms may include options to extend or terminate the lease when it is reasonably certain that the Group will exercise that option.

Lease liabilities include the net present value of the following lease payments: (i) fixed payments; (ii) variable lease payments; and (iii) payments of penalties for terminating the lease if the lease term reflects the lessee exercising that option, if any. Lease liabilities exclude the following payments that are generally accounted for separately: (i) non-lease components, such as maintenance and security service fees and value added tax, and (ii) any payments that a lessee makes before the lease commencement date. The lease payments are discounted using the interest rate implicit in the lease or if that rate cannot be determined, the lessee's incremental borrowing rate being the rate that the lessee would have to pay to borrow the funds in its currency and jurisdiction necessary to obtain an asset of similar value, economic environment and terms and conditions.

An asset representing the right to use the underlying asset during the lease term is recognized that consists of the initial measurement of the operating lease liability, any lease payments made to the lessor at or before the commencement date less any lease incentives received, any initial direct cost incurred by the Group and any restoration costs.

After commencement of the operating lease, the Group recognizes lease expenses on a straight-line basis over the lease term. The right-of-use asset is subsequently measured at cost less accumulated amortization and any impairment provision. The amortization of the right-of-use asset represents the difference between the straight-line lease expense and the accretion of interest on the lease liability each period. The interest amount is used to accrete the lease liability and to amortize the right-of-use asset. There is no amount recorded as interest expense.

Payments associated with short-term leases are recognized as lease expenses on a straight-line basis over the period of the leases.

Subleases of right-of-use assets are accounted for similar to other leases. As an intermediate lessor, the Group separately accounts for the head-lease and sublease unless it is relieved of its primary obligation under the head-lease. Sublease income is recorded on a gross basis separate from the head-lease expenses. If the total remaining lease cost on the head-lease is more than the anticipated sublease income for the lease term, this is an indicator that the carrying amount of the right-of-use asset associated with the head-lease may not be recoverable, and the right-of-use asset will be assessed for impairment.

Prior accounting policy-ASC 840

Leases in which a significant portion of the risks and rewards of ownership are retained by the lessor are classified as operating leases. Payments made under operating leases are charged to the consolidated statements of operations on a straight-line basis over the period of the leases.

Total operating lease rentals for factories and offices for the year ended December 31, 2018 amounted to US$3,759,000. Sublease rentals for the year ended December 31, 2018 amounted to US$254,000.

Income Taxes

The Group accounts for income taxes under the liability method. Under the liability method, deferred income tax assets and liabilities are determined based on the differences between the financial reporting and income tax bases of assets and liabilities and are measured using the income tax rates that will be in effect when the differences are expected to reverse. A valuation allowance is recorded when it is more likely than not that some of the net deferred income tax asset will not be realized.

The Group accounts for an uncertain tax position in the consolidated financial statements only if it is more likely than not that the position is sustainable based on its technical merits and consideration of the relevant tax authority's widely understood administrative practices and precedents. If the recognition threshold is met, the Group records the largest amount of tax benefit that is greater than 50 percent likely to be realized upon ultimate settlement.

The Group recognizes interest and penalties for income taxes, if any, under income tax payable on its consolidated balance sheets and under other expenses in its consolidated statements of operations.

Losses Per Share

Basic losses per share is computed by dividing net loss attributable to the Company by the weighted average number of outstanding ordinary shares in issue during the year. Weighted average number of outstanding ordinary shares in issue excludes treasury shares.

Diluted losses per share is computed by dividing net loss attributable to the Company by the weighted average number of outstanding ordinary shares in issue and dilutive ordinary share equivalents outstanding during the year. Dilutive ordinary share equivalents include ordinary shares and treasury shares issuable upon the exercise or settlement of share-based awards or warrants issued by the Company using the treasury stock method. The computation of diluted losses per share does not assume conversion, exercise, or contingent issuance of securities that would have an anti-dilutive effect.

Segment Reporting

Operating segments are reported in a manner consistent with the internal reporting provided to the chief executive officer who is the Group's chief operating decision maker. The chief operating decision maker reviews the Group's internal reporting in order to assess performance and allocate resources and determined that the Group's reportable segments are as disclosed in Note 26.

Profit Appropriation and Statutory Reserves

The Group's subsidiaries and equity investees established in the PRC are required to make appropriations to certain non-distributable reserve funds.

In accordance with the relevant laws and regulations established in the PRC, the Company's subsidiaries registered as wholly-owned foreign enterprise have to make appropriations from their after-tax profits (as determined under generally accepted accounting principles in the PRC ("PRC GAAP")) to reserve funds including general reserve fund, enterprise expansion fund and staff bonus and welfare fund. The appropriation to the general reserve fund must be at least 10% of the after-tax profits calculated in accordance with PRC GAAP. Appropriation is not required if the general reserve fund has reached 50% of the registered capital of the company. Appropriations to the enterprise expansion fund and staff bonus and welfare fund are made at the respective company's discretion. For the Group's equity investees, the amount of appropriations to these funds are made at the discretion of their respective boards.

In addition, Chinese domestic companies must make appropriations from their after-tax profits as determined under PRC GAAP to non-distributable reserve funds including statutory surplus fund and discretionary surplus fund. The appropriation to the statutory surplus fund must be 10% of the after-tax profits as determined under PRC GAAP. Appropriation is not required if the statutory surplus fund has reached 50% of the registered capital of the company. Appropriation to the discretionary surplus fund is made at the respective company's discretion.

The use of the general reserve fund, enterprise expansion fund, statutory surplus fund and discretionary surplus fund is restricted to the offsetting of losses or increases to the registered capital of the respective company. The staff bonus and welfare fund is a liability in nature and is restricted to fund payments of special bonus to employees and for the collective welfare of employees. All these reserves are not permitted to be transferred to the company as cash dividends, loans or advances, nor can they be distributed except under liquidation.

Recent Accounting Pronouncements

The Group has adopted ASU 2016-13 Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ("ASU 2016-13") on January 1, 2020, which replaced the incurred loss methodology with an expected loss methodology that was referred to as the current expected credit loss ("CECL") methodology. The measurement of expected credit losses under the CECL methodology was applicable to financial assets measured at amortized cost, including cash and cash equivalents, short-term investments, accounts receivable and other receivables. The adoption of ASU 2016-13 did not have a material impact on the Group's consolidated financial statements.

The Group has adopted ASU 2017-04 - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment ("ASU 2017-04") on January 1, 2020, which eliminated step two from the goodwill impairment test and instead requires an entity to recognize an impairment charge for the amount by which the carrying value exceeds the reporting unit's fair value, limited to the total amount of goodwill allocated to that reporting unit. The Group applied ASU 2017-04 prospectively and the adoption did not have a material impact on the Group's consolidated financial statements.

Amendments that have been issued by the Financial Accounting Standards Board or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the Group's consolidated financial statements.

Accounts receivable, other receivables, amounts due from related parties, accounts payable, other payables and amounts due to related parties are carried at cost, which approximates fair value due to the short-term nature of these financial instruments, and are therefore excluded from the above table. Bank borrowings are floating rate instruments and carried at amortized cost, which approximates their fair values, and are therefore excluded from the above table.

Notes:

(a) In June 2020, HBYS entered into an agreement with the government to return the land use right for a plot of land in Guangzhou to the government for cash consideration of up to RMB683.0 million (approximately US$101.2 million) (the "Land Compensation Agreement"). In November 2020, HBYS completed all material obligations as stipulated in the Land Compensation Agreement including the deregistration of the land use right certificate. Therefore, HBYS has recorded the return of leasehold land to the government for RMB569.2 million (approximately US$86 .1 million), resulting in a gain of RMB559.7 million (approximately US$8 4.7 million) after deducting costs of RMB1.7 million (approximately US$0.3 million) to HBYS or RMB475.7 million, net of tax (approximately US$72.0 million). The remaining RMB11 3.8 million (approximately US$ 17.4 million) of cash consideration is conditional upon the receipt of a completion confirmation from the government within 12 months from the date of the Land Compensation Agreement and therefore has not been recognized as at December 31, 2020.

(b) The main entities within each of the HBYS and SHPL groups have been granted the High and New Technology Enterprise ("HNTE") status (the latest renewal of this status covers the years from 2020 to 2022). These entities were eligible to use a preferential income tax rate of 15% for the year ended December 31, 2020 on this basis.

For the years ended December 31, 2020 and 2019, other equity investees had net losses of approximately US$194,000 and net income of approximately US$294,000 respectively. For the year ended December 31, 2018, other equity investees had net losses of approximately US$37,962,000, primarily from Nutrition Science Partners Limited ("NSPL") which incurred research and development expenses and recorded an impairment provision of US$30,000,000 on its intangible assets. In December 2019, the Group acquired the remaining 50% shareholding in NSPL from the equity investee partner and, after the acquisition, it became a subsidiary.

Notes:

(a) The Company calculated its expected volatility with reference to the historical volatility prior to the issuances of share options.

(b) For share options exercisable into ordinary shares, the risk-free interest rates reference the sovereign yield of the United Kingdom because the Company's ordinary shares are currently listed on AIM and denominated in GBP. For share options exercisable into ADS, the risk-free interest rates reference the U.S. Treasury yield curves because the Company's ADS are currently listed on the NASDAQ and denominated in US$.

(c) The Company has not declared or paid any dividends and does not currently expect to do so in the foreseeable future, and therefore uses an expected dividend yield of zero in the Polynomial model.

The Company will issue new shares to satisfy share option exercises. The following table summarizes the Company's share option exercises:

(ii) LTIP

The Company grants awards under the LTIP to participating directors and employees, giving them a conditional right to receive ordinary shares of the Company or the equivalent ADS (collectively the "Awarded Shares") to be purchased by the Trustee up to a cash amount. Vesting will depend upon continued employment of the award holder with the Group and will otherwise be at the discretion of the Board of Directors of the Company. Additionally, some awards are subject to change based on annual performance targets prior to their determination date.

LTIP awards prior to the determination date

Performance targets vary by award, and may include targets for shareholder returns, free cash flows, revenues, net profit after taxes and the achievement of clinical and regulatory milestones. As the extent of achievement of the performance targets is uncertain prior to the determination date, a probability based on management's assessment on the achievement of the performance target has been assigned to calculate the amount to be recognized as an expense over the requisite period with a corresponding entry to liability.

LTIP awards after the determination date

Upon the determination date, the Company will pay a determined monetary amount, up to the maximum cash amount based on the actual achievement of the performance target specified in the award, to the Trustee to purchase the Awarded Shares. Any cumulative compensation expense previously recognized as a liability will be transferred to additional paid-in capital, as an equity-settled award. If the performance target is not achieved, no Awarded Shares of the Company will be purchased and the amount previously recorded in the liability will be reversed through share-based compensation expense.

Granted awards under the LTIP are as follows:

 
                       Maximum cash amount per annum         Covered         Performance target 
 Grant date                  (in US$ millions)           financial years     determination date

Notes:

(a) The annual performance target determination date is the date of the announcement of the Group's annual results for the covered financial year and vesting occurs two business days after the announcement of the Group's annual results for the financial year falling two years after the covered financial year to which the LTIP award relates.

(b) This award does not stipulate performance targets and is subject to a vesting schedule of 25% on each of the first, second, third and fourth anniversaries of the date of grant.

(c) This award does not stipulate performance targets and will be vested on the first anniversary of the date of grant.

(d) This award does not stipulate performance targets and vesting occurs two business days after the announcement of the Group's annual results for the financial year falling two years after the covered financial year to which the LTIP award relates.

The Trustee has been set up solely for the purpose of purchasing and holding the Awarded Shares during the vesting period on behalf of the Company using funds provided by the Company. On the determination date, if any, the Company will determine the cash amount, based on the actual achievement of each annual performance target, for the Trustee to purchase the Awarded Shares. The Awarded Shares will then be held by the Trustee until they are vested.

The Trustee's assets include treasury shares and funds for additional treasury shares, trustee fees and expenses. The number of treasury shares (in the form of ordinary shares or ADS of the Company) held by the Trustee were as follows:

License and collaboration agreement with Eli Lilly

On October 8, 2013, the Group entered into a licensing, co-development and commercialization agreement in China with Eli Lilly and Company ("Lilly") relating to Elunate ("Lilly Agreement"), also known as fruquintinib, a targeted oncology therapy for the treatment of various types of solid tumors. Under the terms of the Lilly Agreement, the Group is entitled to receive a series of payments up to US$86.5 million, including upfront payments and development and regulatory approval milestones. Development costs after the first development milestone are shared between the Group and Lilly. Elunate was successfully commercialized in China in November 2018, and the Group receives tiered royalties in the range of 15% to 20% on all sales in China.

In December 2018, the Group entered into various amendments to the Lilly Agreement (the "2018 Amendment"). Under the terms of the 2018 Amendment, the Group is entitled to determine and conduct future life cycle indications ("LCI") development of Elunate in China beyond the three initial indications specified in the Lilly Agreement and will be responsible for all associated development costs. In return, the Group will receive additional regulatory approval milestones of US$20 million for each LCI approved, for up to three LCI or US$60 million in aggregate, and will increase tiered royalties to a range of 15% to 29% on all Elunate sales in China upon the commercial launch of the first LCI. Additionally, through the 2018 Amendment, Lilly has provided consent, and freedom to operate, for the Group to enter into joint development collaborations with certain third-party pharmaceutical companies to explore combination treatments of Elunate and various immunotherapy agents. The 2018 Amendment also provided the Group rights to promote Elunate in provinces that represent 30% to 40% of the sales of Elunate in China upon the occurrence of certain commercial milestones by Lilly. Such rights were further amended below.

In July 2020, the Group entered an amendment to the Lilly Agreement (the "2020 Amendment") relating to the expansion of the Group's role in the commercialization of Elunate across all of China. Under the terms of the 2020 Amendment, the Group is responsible for providing promotion and marketing services, including the development and execution of all on-the-ground medical detailing, promotion and local and regional marketing activities, in return for service fees on sales of Elunate made by Lilly. In October 2020, the Group commenced such promotion and marketing services. In addition, development and regulatory approval milestones for an initial indication under the Lilly Agreement were increased by US$10 million in lieu of cost reimbursement.

Upfront and cumulative milestone payments according to the Lilly Agreement received up to December 31, 2020 are summarized as follows:

 
                                           (in US$'000) 
Upfront payment                                   6,500 
Development milestone payments achieved          40,000 
                                           ============ 
 

Under ASC 606, the Group identified the following performance obligations under the Lilly Agreement: (1) the license for the commercialization rights to Elunate and (2) the research and development services for the specified indications. The transaction price includes the upfront payment, research and development cost reimbursements, milestone payments and sales-based royalties. Milestone payments were not included in the transaction price until it became probable that a significant reversal of revenue would not occur, which is generally when the specified milestone is achieved. The allocation of the transaction price to each performance obligation was based on the relative standalone selling prices of each performance obligation determined at the inception of the contract. Based on this estimation, proportionate amounts of transaction price to be allocated to the license to Elunate and the research and development services were 90% and 10% respectively. Control of the license to Elunate transferred at the inception date of the agreement and consequently, amounts allocated to this performance obligation were recognized at inception. Conversely, research and development services for each specified indication are performed over time and amounts allocated are recognized over time using the prior and estimated future development costs for Elunate as a measure of progress. Royalties are recognized as future sales occur as they meet the requirements for the sales-usage based royalty exception.

The 2018 Amendment is a separate contract under ASC 606 as it added distinct research and development services for the LCIs to the Lilly Agreement. As at December 31, 2020, no LCI regulatory approval milestones were achieved. The 2020 Amendment related to the promotion and marketing services is a separate contract under ASC 606 as it added distinct services to the Lilly Agreement. Such promotion and marketing services are recognized over time based on amounts that can be invoiced to Lilly. The 2020 Amendment related to the additional development and regulatory approval milestone amounts is a modification under ASC 606 as it only affected the transaction price of research and development services for a specific indication under the Lilly Agreement, and therefore, such additional milestone amounts will be included in the transaction price accounted under the Lilly Agreement once the specified milestones are achieved. As at December 31, 2020, no additional development and regulatory approval milestone amounts were achieved.

Revenue recognized under the Lilly Agreement by transaction price type is as follows:

 
                                                                    Year Ended December 31,

Note: During the years ended December 31, 2020 and 2019, no milestones were achieved. During the year ended December 31, 2018, the Group achieved milestones in relation to the acceptance and approval respectively, of a new drug application by the National Medical Products Administration of China for Elunate as a treatment of patients with advanced colorectal cancer.

License and collaboration agreement with AstraZeneca

On December 21, 2011, the Group and AstraZeneca AB (publ) ("AZ") entered into a global licensing, co-development, and commercialization agreement for savolitinib ("AZ Agreement"), a novel targeted therapy and a highly selective inhibitor of the c-Met receptor tyrosine kinase for the treatment of cancer. Under the terms of the AZ Agreement, the Group is entitled to receive a series of payments up to US$140 million, including upfront payments and development and first-sale milestones. Additionally, the AZ Agreement contains possible significant future commercial sale milestones. Should savolitinib be successfully commercialized outside China, the Group would receive tiered royalties from 9% to 13% on all sales outside of China. Should savolitinib be successfully commercialized in China, the Group would receive fixed royalties of 30% based on all sales in China. Development costs for savolitinib in China will be shared between the Group and AZ, with the Group continuing to lead the development in China. AZ will lead and pay for the development of savolitinib for the rest of the world.

In August 2016 (as amended in December 2020), the Group entered into an amendment to the AZ Agreement whereby the Group shall pay the first approximately US$50 million of phase III clinical trial costs related to developing savolitinib for renal cell carcinoma ("RCC"), and remaining costs will be shared between the Group and AZ. Subject to approval of savolitinib in RCC, the Group would receive additional tiered royalties on all sales outside of China, with the incremental royalty rates determined based on actual sharing of development costs.

Upfront and cumulative milestone payments according to the AZ Agreement received up to December 31, 2020 are summarized as follows:

 
                                          (in US$'000) 
Upfront payment                                 20,000 
Development milestone payments achieved         25,000 
 

Under ASC 606, the Group identified the following performance obligations under the AZ Agreement: (1) the license for the commercialization rights to savolitinib and (2) the research and development services for the specified indications. The transaction price includes the upfront payment, research and development cost reimbursements, milestone payments and sales-based royalties. Milestone payments were not included in the transaction price until it became probable that a significant reversal of revenue would not occur, which is generally when the specified milestone is achieved. The allocation of the transaction price to each performance obligation was based on the relative standalone selling prices of each performance obligation determined at the inception of the contract. Based on this estimation, proportionate amounts of transaction price to be allocated to the license to savolitinib and the research and development services were 95% and 5% respectively. Control of the license to savolitinib transferred at the inception date of the agreement and consequently, amounts allocated to this performance obligation were recognized at inception. Conversely, research and development services for each specified indication are performed over time and amounts allocated are recognized over time using the prior and estimated future development costs for savolitinib as a measure of progress.

Revenue recognized under the AZ Agreement by transaction price type is as follows:

Notes:

(a) The Company, three subsidiaries incorporated in the British Virgin Islands and its Hong Kong subsidiaries are subject to Hong Kong profits tax. In March 2018, the Hong Kong two-tiered profits tax rates regime was signed into law under which the first HK$2.0 million (US$0.3 million) of assessable profits of qualifying corporations will be taxed at 8.25%, with the remaining assessable profits taxed at 16.5%. Hong Kong profits tax has been provided for at the relevant rates on the estimated assessable profits less estimated available tax losses, if any, of these entities as applicable.

(b) Taxation in the PRC has been provided for at the applicable rate on the estimated assessable profits less estimated available tax losses, if any, in each entity. Under the PRC Enterprise Income Tax Law (the "EIT Law"), the standard enterprise income tax rate is 25%. In addition, the EIT Law provides for a preferential tax rate of 15% for companies which qualify as HNTE. HMPL and its wholly-owned subsidiary Hutchison MediPharma (Suzhou) Limited qualify as a HNTE up to December 31, 2022 and 2020 respectively.

Pursuant to the EIT law, a 10% withholding tax is levied on dividends paid by PRC companies to their foreign investors. A lower withholding tax rate of 5% is applicable under the China-HK Tax Arrangement if direct foreign investors with at least 25% equity interest in the PRC companies are Hong Kong tax residents, and meet the conditions or requirements pursuant to the relevant PRC tax regulations regarding beneficial ownership. Since the equity holders of the equity investees of the Company are Hong Kong incorporated companies and Hong Kong tax residents, and meet the aforesaid conditions or requirements, the Company has used 5% to provide for deferred tax liabilities on retained earnings which are anticipated to be distributed. As at December 31 , 2020, 2019 and 2018, the amounts accrued in deferred tax liabilities relating to withholding tax on dividends were determined on the basis that 100% of the distributable reserves of the equity investees operating in the PRC will be distributed as dividends.

(c) The Company's subsidiary in the U.S. with operations in New Jersey and New York states is subject to U.S. taxes, primarily federal and state taxes, which have been provided for at approximately 21% (federal) and 9% to 16.55% (state tax) on the estimated assessable profit over the reporting years. Certain income receivable by the Company is subject to U.S. withholding tax of 30%. One of the Group's subsidiaries is subject to corporate tax in EU countries at 19% or 20% on the estimated assessable profits in relation to its permanent establishment in these countries in 2020 and/or 2019.

The reconciliation of the Group's reported income tax expense to the theoretical tax amount that would arise using the tax rates of the Company against the Group's loss before income taxes and equity in earnings of equity investees is as follows:

 
                                                                         Year Ended December 31,

The Company believes that it is more likely than not that future operations will not generate sufficient taxable income to realize the benefit of the deferred tax assets. The Company's subsidiaries have had sustained tax losses, which will expire within five years if not utilized in the case of PRC subsidiaries (ten years for HNTEs), and which will not be utilized in the case of Hong Kong subsidiaries as they do not generate taxable profits. Accordingly, a valuation allowance has been recorded against the relevant deferred tax assets arising from the tax losses.

The table below summarizes changes in the deferred tax valuation allowance:

Notes:

25. Losses Per Share

   (i)   Basic losses per share 

Basic losses per share is calculated by dividing the net loss attributable to the Company by the weighted average number of outstanding ordinary shares in issue during the year. Treasury shares held by the Trustee are excluded from the weighted average number of outstanding ordinary shares in issue for purposes of calculating basic losses per share.

 
                                                                         Year Ended December 31, 
                                                                     2020         2019         2018 
Weighted average number of outstanding ordinary shares in issue   697,931,437  665,683,145  664,263,820 
Net loss attributable to the Company (US$'000)                      (125,730)    (106,024)     (74,805) 
Losses per share attributable to the Company (US$ per share)           (0.18)       (0.16)       (0.11) 
 

(ii) Diluted losses per share

Diluted losses per share is calculated by dividing net loss attributable to the Company by the weighted average number of outstanding ordinary shares in issue and dilutive ordinary share equivalents outstanding during the year. Dilutive ordinary share equivalents include shares issuable upon the exercise or settlement of share option, LTIP awards and warrants issued by the Company using the treasury stock method.

For the years ended December 31, 2020, 2019 and 2018, the share options, LTIP awards and warrants issued by the Company were not included in the calculation of diluted losses per share because of their anti-dilutive effect. Therefore, diluted losses per share were equal to basic losses per share for the years ended December 31, 2020, 2019 and 2018.

26. Segment Reporting

The Group's operating segments are as follows:

(i) Oncology/Immunology: focuses on discovering, developing, and commercializing targeted therapies and immunotherapies for the treatment of cancer and immunological diseases. Oncology/Immunology is further segregated into two core business areas:

(a) R&D: comprises research and development activities covering drug discovery, development, manufacturing and regulatory functions as well as administrative activities to support research and development operations; and

(b) Marketed Products: comprises the sales, marketing, manufacture and distribution of drug developed from research and development activities.

(ii) Other Ventures: comprises other commercial businesses which include the sales, marketing, manufacture and distribution of other prescription drugs and over-the-counter pharmaceuticals as well as consumer health products.

The performance of the reportable segments is assessed based on segment operating (loss)/profit.

In the second half of 2020, the Group (1) renamed the Innovation Platform to Oncology/Immunology segment and Commercial Platform to Other Ventures segment; and began (2) separately presenting R&D activities in the U.S. and other locations under Oncology/Immunology segment, (3) including the results from manufacturing and commercializing Elunate under Marketed Products in Oncology/Immunology segment, and (4) aggregating the remaining commercial businesses under Other Ventures segment with Hong Kong included within the PRC. These changes are consistent with the chief operating decision maker's view of the business. The segment information below as at and for the years ended December 31, 2019 and 2018 have been revised so that all segment disclosures are comparable.

28. Litigation

From time to time, the Group may become involved in litigation relating to claims arising from the ordinary course of business. The Group believes that there are currently no claims or actions pending against the Group, the ultimate disposition of which could have a material adverse effect on the Group's results of operations, financial position or cash flows. However, litigation is subject to inherent uncertainties and the Group's view of these matters may change in the future. When an unfavorable outcome occurs, there exists the possibility of a material adverse impact on the Group's financial position and results of operations for the periods in which the unfavorable outcome occurs, and potentially in future periods.

On May 17, 2019, Luye Pharma Hong Kong Ltd. ("Luye") issued a notice to the Group purporting to terminate a distribution agreement that granted the Group exclusive commercial rights to Seroquel in the PRC for failure to meet a pre-specified target. The Group disagrees with this assertion and believes that Luye have no basis for termination. As a result, the Group commenced legal proceedings in 2019 in order to seek damages. As at December 31, 2020, the legal proceedings are still in progress. Accordingly, no adjustment has been made to Seroquel-related balances as at December 31, 2020, including accounts receivable, long-term prepayment, accounts payable and other payables of US$1.2 million, US$1.0 million, US$0.9 million and US$1.2 million respectively.

29. Restricted Net Assets

Relevant PRC laws and regulations permit payments of dividends by the Company's subsidiaries in the PRC only out of their retained earnings, if any, as determined in accordance with PRC accounting standards and regulations. In addition, the Company's subsidiaries in the PRC are required to make certain appropriations of net after-tax profits or increases in net assets to the statutory surplus fund prior to payment of any dividends. In addition, registered share capital and capital reserve accounts are restricted from withdrawal in the PRC, up to the amount of net assets held in each subsidiary. As a result of these and other restrictions under PRC laws and regulations, the Company's subsidiaries in the PRC are restricted in their ability to transfer their net assets to the Group in terms of cash dividends, loans or advances, with restricted portions amounting to US$0.2 million and US$0.3 million as at December 31, 2020 and 2019 respectively, which excludes the Company's subsidiaries with a shareholders' deficit. Even though the Group currently does not require any such dividends, loans or advances from the PRC subsidiaries, for working capital and other funding purposes, the Group may in the future require additional cash resources from the Company's subsidiaries in the PRC due to changes in business conditions, to fund future acquisitions and development, or merely to declare and pay dividends to make distributions to shareholders.

In addition, the Group has certain investments in equity investees in the PRC, where the Group's equity in undistributed earnings amounted to US$99.9 million and US$61.6 million as at December 31, 2020 and 2019 respectively.

30. Subsequent Events

The Group evaluated subsequent events through March 4, 2021, which is the date when the consolidated financial statements were issued.

In January 2021, the Group entered into a contract with a third party contractor for approximately US$46.8 million in connection with the construction of a factory in Shanghai.
